Steel prefabricated houses are becoming the choice of more and more people

The safety of the house is the first premise of building a house. The firmness of the house is the key issue that the residents are concerned about. If an earthquake strikes, can your house stand on that land after the disaster?

The following basic requirements are put forward for the seismic design of houses

1. Structure Type of steel prefab house

Common structural systems of steel structure housing include frame structure, frame-support structure, frame-seismic wallboard structure, simplified structure and mega-frame structure. The seismic performance of steel structure housing depends on the type selection of structure. In actual engineering design, various factors need to be comprehensively considered to optimize the scheme, and the appropriate structural system should be determined in the optimization process.

2. Principles of Structural Arrangement of steel structure housing

The choice of steel structure housing’s structural system and structural arrangement is related to the safety, applicability and economy of the structure. Like other types of building structures, multi-storey and high-rise steel structure housing should try to adopt regular building schemes. When the structure is complicated and the plane elevation is especially irregular, shockproof continuation can be arranged at appropriate positions according to actual needs, thus forming a plurality of more regular lateral force resistant structural units. As the structural deformation that the steel structure can withstand is larger than that of the concrete structure, generally speaking, it is not appropriate to set up anti-seismic joints. When necessary, the width of the anti-seismic joints should not be less than 1.5 times of the corresponding reinforced concrete structure houses.

3. Maximum height and aspect ratio applicable to steel structure housing

According to the overall height of the structure and the seismic fortification intensity, the structure type and the maximum applicable height are determined. The aspect ratio of the structure is an important parameter that affects the overall stability and seismic performance of the structure. It has a direct impact on the stiffness, lateral displacement and vibration form of the structure. Height ratio refers to the ratio of the total height of the house to the smaller width of the plane. When the aspect ratio value is large, on the one hand, the structure will produce large horizontal displacement and P – A effect, and on the other hand, the overturning moment will produce large axial force on the column. Therefore, it is necessary to set a limit value for the maximum aspect ratio of steel structure housing, which should not be greater than a reasonable limit value. In case of exceeding the limit value, special research should be conducted and necessary anti-seismic measures should be taken.

With people’s continuous understanding of earthquakes, in order to prevent the occurrence of serious earthquake disasters, causing property losses and casualties. People’s seismic requirements for high-rise steel structure housing are constantly improving. In the seismic design of high-rise steel structure housing, we should first start with conceptual design and formulate a more reasonable design scheme to ensure the realization of the seismic fortification target of the building.

Prefabricated houses look like houses built on site

In a standing-room-only presentation at the Malibu Library Sunday, local residents and fire victims flocked to hear presentations from three LA-area prefabricated homes manufacturers. Prefabricated homes are built in sections in large warehouse-like facilities, eliminating weather damage or delays, then moved to the site and assembled. They’ve come a long way from the “manufactured homes” of yesteryear and the industry has evolved to the point where their homes look the same as homes built on-site.

The “prefab” or “modular” option is apparently being looked at seriously by a number of Malibu’s fire burnouts, not only as primary residences, but as temporary residences and accessory dwelling units, or “granny flats,” as they’re sometimes called. Some of the biggest reasons for their appeal are that prefabs cost less and are faster to build than an on-site construction, but have comparable quality.

The industry reps say that one of the first steps someone should take when considering a prefab is to request a site survey to make sure the property and the road leading up to it will facilitate the structure. The modules built by some companies are 16 feet wide and would need a road at least that wide to be transported to the property. Other companies make housing modules only eight feet wide. All of the companies make units small enough to fit City of Malibu rules for the size of a temporary residence and/or ADU.

The prefab companies all maintain that their building materials and designs are as fireproof as possible. “We use steel frames and bolts, metal siding, roof sprinklers and a continuous membrane across the roof,” one said, “as well as roof designs without eves or overhangs that could let embers in.” “Any new homes, including ours, are going to be a thousand times more fire resistant than anything built in the 1940s or 50s,” one added, “just because of all the new regulations.”

In addition, they say their homes have to meet California seismic standards for earthquakes, and that “being quake-proof also means they’re wind-proof.”

In response to questions about cost, some give a ballpark price of about $250/square foot, and costs are quoted up front. Most companies will allow buyers to tour their factories and see their homes being built. Some are willing to competitively bid the pre-delivery site work.

Light steel frame is accepted and favored by more and more owners

Abundant agriculture has a strong foundation, rich farmers have a prosperous country, and stable rural areas have a stable society. With the continuous development and progress of the society, the development strategies of industry supporting agriculture and city supporting rural areas have been gradually implemented. The construction of new rural areas has been raised to a new height. More and more new rural villas have sprung up in China.

Light steel villa house is accepted and favored by more and more owners for its advantages of stable structure, low cost, short construction period and large space span. At the same time, the light steel structure has a light weight, and its weight per unit area is only 1/4 of the weight of brick-concrete structure with the same area, so its foundation treatment is simple and suitable for most geological conditions. It can be seen that it is the general trend for light steel structure housing to replace brick-concrete structure and wood structure housing with its revolutionary advantages.

Putian light steel frame is a light steel structure residential building independently developed, designed, manufactured and installed by PTH. PTH Light steel villa is a kind of modular house, consisting of cold form, thin-walled light steel keel system.

The key lies in how to organize industrial production

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.

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.

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.
