The steel structure quality of Putian House can definitely stand the test

Steel structure is a structural composed of steel materials, which is one of the main building structure types. Steel structure warehouses installation quickly , the structure is mainly composed of steel beams, steel columns, steel trusses and other components made of shaped steel and steel plate, etc., and usually welded, bolted or riveted joints are used between each member or component , because of its light weight and simple construction, is widely used in large factory buildings, venues, super high-rise and other fields.

  1. Before the steel structure is installed, all kinds of records and reports should be checked, such as quality certificate of components, material test report, non-destructive inspection report of welding seam, etc., and the appearance of components should be checked to see if they conform to the design requirements, and the problems should be corrected immediately.
  2. The installation flow chart of the steel structure is drawn and installed according to the flow chart. The precision of all anchor bolts should be checked before installation, and the spatial position and design drawing should be corrected timely to ensure the accuracy of anchor bolts.
  3. The mounting sequence of the components should be carefully designed to form a rigid body as soon as possible so that the installation can be continued in a stable state, and also to eliminate errors in the installation of the steel structure.
  4. Component assembly should undertake the necessary checking calculation. The lateral stiffness of small component measures should be taken to avoid the distortion and damage.
  5. In the process of columns or steel structure installation, beam and steel support should be installed in a timely manner, temporary fixed cable wind rope should be added when necessary.
  6. It should pay attention to controlling the influence of temperature difference on the perpendicularity of components for the installation of steel column, adjust the lateral quantity to the perpendicularity of the first determined standard column, and check other columns.
  7. When the column is installed, the positioning axis of each column must be directly drawn from the control axis on the ground, and the top axis of the column of the next column shall not be used as the positioning axis of the upper column.
  8. Steel structure installation spot welding environment, welding position, high altitude, air temperature and humidity adverse effects for susceptible to weld defect, therefore, must take appropriate measures to overcome the impact of these unfavorable factors. The unqualified weld rework repair is not allowed to exceed twice.
  9. High strength bolts using torque wrench must be correction calibration before use, should check after use, once found that the torque error exceed the permitted range, the twist of the wrench bolt were all unqualified.

The high-strength bolts should be tested after final screw, and the nuts can be tested one by one by means of small hammering. Torque should also be sampled check.

  1. After the Steel structure installation is completed, and correct after correction, it should do the second grouting in time for the space between the column bottom and top of the base to make sure the surface contact base plate and foundation top tight.
  2. After completion of the whole steel structure installation, it should be according to “the steel structure engineering construction quality acceptance standard “(GB 50205-2001) requirements for acceptance.

Light steel villas have excellent quality and friendly prices

We all have a dream that we can own a villa of our own, which is not necessarily very big, but must be comfortable, must be beautiful and must not cost too much. Which villa is cheap, comfortable and beautiful? That is light steel villa house, a stunning new product.

The biggest characteristics of this kind of house are safety, comfort and fast construction speed. Because his load-bearing structure is light steel structure and its shape is particularly beautiful, this new type of house is called a light steel villa.

Then why is the cost of light steel villa low?

Our traditional house building needs steel, cement, red brick and other main materials. The price of these building materials is getting higher and higher with the development of economy. In addition, a lot of human resources are needed in the construction process. The labor cost is also very high now. The combination of various factors results in the cost of an ordinary house reaching more than 100,000 or even higher. With the advancement of time, the cost of traditional houses will continue to rise.

Light steel villas have three characteristics. One is that the components of the houses are all produced in workshops, with high degree of mechanization, high production efficiency, good quality and relatively low price. Second, the materials are all new materials that are green and environment – friendly. They are heat-insulating and very light in weight. 90% of the materials can be recycled. Third, the installation speed is fast, and the construction period of a 200 square meter villa does not exceed 2 months, which saves a lot of labor costs.

Light steel villas are not only beautiful, the service life of the main structure is 90 years, but our traditional houses have become dilapidated buildings after more than 30 years of use, with almost no aesthetic feeling to speak of. From a long-term perspective, light steel villas are very cost – effective.

Light gauge steel villas are loved by more and more ordinary people for their excellent quality and friendly prices. They are recognized and promoted by the government for their advantages of energy conservation and environmental protection. It can be predicted that in the near future, farmers across the country will be able to live in safe and comfortable light gauge steel villas and realize the goal of building ” beautiful countryside”.

Prefabricated houses comply with the same strict legal requirements as traditional houses

New Waverley Street house trucked in and constructed in eight hours. Bicyclists in the area stop to watch as construction worker use a large crane to hoist and install a prefabricated house piece on Waverley Stree.

A crane lowers the third of six prefabricated house pieces onto the concrete foundation on Wavelery Street in Palo Alto where a home was replaced in eight hours.

While images of trailer parks with shoddy construction and design may come to mind when people hear the word “prefabricated,” today’s pre-built homes are anything but. Prefabs are required by law to adhere to the same stringent requirements as conventionally-built homes, and many home builders are using state-of-the art design and construction methods.

“Prefabrication is a more predictable way to build,” said tobylongdesign’s CEO Toby Long. “The building is designed and specified completely before the construction process starts, which is not how conventional projects go. Prefab also can be faster than conventional building. We overlap the building and the site work with construction. It can happen simultaneously.”

The Waverley home only took a matter of months from the moment the homeowners decided to build to move-in day. Most conventional home builds can take more than a year to complete, Long added.

Long also surmises that there’s a growing interest from consumers and sees prefabricated buildings as not only part of the future of construction, but as part of the present. I think that prefab is going to become part of our mainstream construction language.

Green Building System of Light Steel Houses Conforming to Sustainable Development Policy

Prefabricated houses, i.e. houses built in prefab housing, use industrialized production methods. Some or all components of houses are prefabricated in factories and then transported to the construction site. Houses built by assembling components through reliable connection methods are called Residential industrialization or industrialized houses in Europe, America and Japan. Prefabricated houses are mainly divided into three development modes: prefabricated reinforced concrete structure, prefabricated lightweight steel structure and prefabricated Container house.

Today, let’s talk about prefabricated steel structure housing.

Steel structures in advanced foreign countries have exceeded 50%, Japan has reached 70%, while in China less than 10%, more than 90% are still RC structures. China’s steel structure residential buildings must be vigorously developed. Chinese real estate developers should be able to see business opportunities from it. The key lies in how to organize industrial production.

Industrialized production will surely promote new growth points in China’s economic development. If the development of RC structure makes the construction from manual to mechanized, then the application of steel structure will certainly modernize the residential construction.

Light gauge steel house has the characteristics of light weight, large span, good wind and earthquake resistance, excellent thermal insulation, sound insulation and other indicators. It is a green building system with high efficiency, energy saving, environmental protection and in line with the policy of sustainable development.

It is suitable for villas, multi-storey houses, holiday villages, clubs and other civil buildings as well as building floors, flat roofs, light internal partitions and so on. Can be pre-assembled, the wall includes pre-installed exterior wall enclosure, insulation and windows. The roof truss system can also be provided to developers in the form of pre-assembly, which greatly shortens the construction period compared with traditional construction methods.

Low cost prefab house fully demonstrated the creativity of architects

One of the biggest factors that can restrict or constrain a project is the budget. Low budget requires architects to make more efforts to ensure the quality of the whole project. Since the construction budget of most houses is lower than the requirements of architects, we think it is necessary to discuss several outstanding cases in which architects have fully demonstrated the creativity of architects by creating high-quality solutions to solve the “problems” of low budget.

The following is an introduction to these low cost prefab houses.

  1. Casa Vila Matilde residence in sã o paulo/terraetuma arquitos associados

At the beginning of 2014, the residential building became even more dilapidated and crumbling. For this reason, Ms. Dalva who lives here can only rent the house of her relatives in inside. The renovation of the old house must be stepped up, otherwise she will soon use up all her savings. According to our latest experience, we have transformed the original building into a low-cost residential building with accurate design and good flexibility.

2.Bovero residence/German Müller

The tight budget allowed the architect to decide not to carry out exterior wall decoration after completion, but to display all kinds of building materials during construction. These materials determine the color and texture of the building, which also shows the stealth technology in this process.

3.Casa dos Caseiros self-built house/24.7 arquitetura design

“Casa dos Caseiros” residential project is the first private order project built for social benefit residential projects, and many such projects will be built in some cities in Rio de Janeiro state.

4.House in La Prosperina residential project/Fabrica Nativa Arquitectura

Due to limited budget, we have made great determination to use some recycled materials in the construction of the project. We re-used the original 4.80m× 5.50m building: roof, sanitary facilities, three flour in four flour The Wall, bathroom, half floor made of wood and particleboard.

5.Gutter House slum/Nú cleo de Arquiteta Expemental

After the site was selected, the biggest challenge we encountered was how to overcome the limitations of Brazilian residential buildings, such as the “My Life, My Home” housing plan in Minha Casa Minha Vida, etc., which enabled these new houses to have modern architectural concepts, functions, technologies and aesthetic qualities. However, the low cost requires more dexterity in the construction of houses, and the choice of building materials and new building technologies are used to optimize the internal space.

What are the advantages and disadvantages of Container architecture?

Expandable container houses is a kind of convenient movable house. This kind of reformed house is gradually accepted by everyone for this kind of building. So, what are the advantages and disadvantages of this kind of Container architecture?

Advantages and Disadvantages of Container architecture

The advantages of containers are as follows:

1. Dimension Standard

Container has standardized size due to its own characteristics, so it has stronger adaptability in modular application, and can freely combine in various forms to create more diverse modes. Moreover, by utilizing the characteristics, the application organization design of the container is more standard, the manufacturing process is simpler and more convenient, the manufacturing cost is saved, and greater benefits can be obtained.

2, the availability of resources is strong

If the container is 12m in length and 29m2 in area, the price is about 15000 yuan. If the same area is constructed with brick-concrete structure, the cost price will reach 800 yuan /m2 and the total cost will reach 23200 yuan. However, if the container is constructed with steel-concrete construction materials, the cost price will be higher, reaching 29000 yuan per square meter in 1000 yuan.

3. simple structure

As the Container architecture is built based on the container structure, it has a simpler construction environment, greatly shortens the construction Period, can be conveniently disassembled and assembled, and can be moved to any place, just like building blocks, and only needs to fully and firmly fix the container structure together with steel members.

In addition to its advantages, there are also some disadvantages. Here are some of them to introduce to you:

1. The main reason for the high house price is the high price of land. If you buy a housing box, you should consider renting the land when you put containers in it. Have you considered the price? At present, there are two kinds of housing boxes. One is the foam sandwich panel used in the side panel, which is very weak, has a short service life and does not prevent theft. Although the anti-theft effect is much better if the traditional container is refitted, the heat insulation and sound insulation effects are relatively poor and the interior decoration is required.

2. The whole housing box is made of steel, so the decoration is more difficult than that of ordinary houses. The decoration cost is high. 4. The area of a single container is very small. If you use multiple containers for splicing, the waterproofing at the splicing place is not good and needs regular maintenance.

3. At present, domestic container paints are all made in Oil Paint, which is quite harmful to human body.

Some Characteristics of Steel Structure Warehouse

The steel structures warehouse mainly means that the main load-bearing members are composed of steel. Including steel pillars, steel beams, steel structure foundations, steel roof trusses (basically now are steel structure trusses ), steel roofs, steel walls can also be maintained with brick walls. Due to the increase in steel production of China, many have begun to adopt steel structure warehouses, and can also be divided into light and heavy steel structure warehouses. Industrial and civil construction facilities constructed of steel are called steel structures.

The steel structure warehouse has a lightweight, high strength, good overall rigidity, and strong deformation ability. The building’s own weight is only one-fifth of the brick-concrete structure, which can withstand hurricanes of 70 meters per second, so that life and property can be effectively protected. The steel structure residential structure is composed of cold-formed thin-walled steel component system. The steel bone is made of super anti-corrosion high-strength cold-rolled galvanized sheet, which effectively avoids the influence of corrosion of the steel plate during construction and use, and increases the service life of the light steel component. The structural life can reach 100 years.

The sound insulation effect is an important indicator for evaluating the house. The windows installed in the steel system are all made of insulating glass. The sound insulation effect is good, and the sound insulation is more than 40 decibels. The wall made up of light steel keel and thermal insulation gypsum board can have a sound insulation effect of up to 60. Decibel The steel wall adopts an energy-efficient system, has a breathing function, and can adjust the indoor air dry humidity; the roof has a ventilation function, which can form a flowing air between the interior of the house to ensure the ventilation and heat dissipation requirements inside the roof.

When the surface temperature of the steel is within 150 ° C, the strength of the steel changes little, so the steel structures are suitable for use for/of a hot shop. When the temperature exceeds 150 ° C, its strength is significantly reduced. When the temperature reaches 500-600t, the intensity is almost zero. Therefore, in the event of a fire, the steel structure has a short fire-resisting time and a sudden collapse occurs. For steel structures of special requirements. Insulation and fire resistance measure is required.

There are many reasons for the difficulty in guaranteeing the quality of steel structure engineering. It is also complicated. It has problems caused by improper process, problems caused by violation of process operation, problems caused by the technical level and responsibility of construction workers and decision makers. Quality problems caused by mistake.

Prefabrication is getting more and more attention from the market

It is not breaking news that the building industry is one of the biggest pollutant and energy users, globally. But, as industry heads have experienced the market’s reaction and changing priorities, we’ve seen a substantial shift in production methods. This evolution has given birth to a Green or sustainable building movement, along with the emergence of standards and certifications that raise the bar for even more creative and sustainable architecture.

As well, advancements in factory production technologies and building methods have led to the emergence of a new prefab and modular building trend. This prefab trend allows for hyper-efficient production, optimally efficient homes, integration of leading edge technologies, and ultimately a more sustainable way of living.China prefabricated homes have developed quite well over the years.

In years past, prefab homes were known for poor quality and inferior design. Today however, prefab developers are designing award-winning, luxurious, smart, sustainable homes and buildings.

This inflection of the modular manufacturing trend can be traced back to the emergence of various manufacturing technologies, increased demand for more sustainable structures, and communities need affordable housing solutions after natural disasters. The solutions had to go beyond temporary disaster-relief housing.

In recent years, China has also followed the world’s footsteps and begun to be interested in sustainable reconstruction. They have promulgated policies to support the prefabrication field, so that architects and modular design of housing solutions are consistent and green and high-performance building standards are achieved.
