The Knowledge of Steel Structure Engineering Construction

Mar. 12, 2020

Steel structure engineering is a structure made mainly of steel, which is one of the main types of building structures. Steel structure is one of the more common structural forms in modern building engineering.

At present, the application of steel structure has greatly developed, both in quantity and quality far exceed the past.

It has reached a high level in terms of design, manufacturing and installation technology, mastered the design and construction technology of various complex buildings, and has built many large-scale and complex-structure steel structure workshops and large-span steel structures for civilian use Construction and railway bridges.

Road bridges and so on.

The floor of the prefabricated house is composed of cold-formed thin-walled steel frames or composite beams, OSB structural panels on the floor, supports, and connectors. The materials used are oriented particle board, cement fiberboard, and plywood. These lightweight floors can withstand loads of 316 to 365 kg per square meter. The weight of the floor structure system of maite prefabricated houses is only one-fourth to one-sixth that of the traditional domestic concrete floor system.

The residential roof system is composed of roof trusses, structural OSB panels, waterproof layers, and light roof tiles (metal or asphalt tiles). The roofs of prefabricated houses in Meite can be combined in many ways. There are also many materials. Under the premise of ensuring the waterproof technology, there are many options for the appearance.

2. Wall structure of custom steel construction warehouse

The wall of the prefabricated house is mainly composed of wall frame columns, wall top beams, wall bottom beams, wall supports, wall panels and connectors. Maite building prefabricated houses generally use internal cross walls as load-bearing walls of the structure, and the wall columns are shaped light steel members. The wall thickness is determined by the load. It is usually 0.84 ~ 2 mm, and the distance between the wall columns is 400 ~ 600 mm, Maite Building Prefabricated House This kind of wall structure layout can withstand and transfer vertical loads, and it is convenient to arrange, but Maite Building Prefabricated House's wall structure cannot bear horizontal loads.

3. Low-cost prefabricated house building insulation energy saving technology

In order to ensure the insulation effect of prefabricated houses, the thermal insulation materials used in the exterior walls and roofs of buildings can be used for a long time and can be thermally insulated. In addition to filling fiberglass between the pillars of the wall, the prefabricated house of Maite Building is generally affixed with a layer of insulation material on the outside of the wall. , Reduce the heat transfer through the floor, all interior wall walls are filled with glass fiber between the columns, reducing the heat transfer between the walls of the house.

4. Building fire protection technology

One of the key problems of prefabricated houses is the application of fire protection technology. The fire resistance rating of Maite's prefabricated houses is Grade 4. The matte building prefabricated house is affixed with fire-resistant gypsum board on both sides of the wall and the ceiling of the floor. For ordinary firewalls and individual walls, it is protected by 25.4 mm thick 1-inch gypsum board to meet the fire protection requirements for one hour. The fiberglass filled between the wall pillars and the floor joists also plays an active role in protecting fire and heat.

5. Building sound insulation technology

The prefabricated house is filled with glass wool between the inner and outer walls and the floor joist to prevent the audio part transmitted through the air. For the impact sound transmitted through the solid, the following structural treatments are used: Two walls in the middle gap; and for the small keel of the fixed gypsum board for the ceiling, the elastic structure with small cutouts is used to effectively reduce the solid sound transmission between floors.
