Steel Shed: What is the technical performance of the steel structure?

The editor will tell you about the technical performance of steel structure today. Steel structure is a structure composed of steel materials. It is the main structure of steel shed. It is a relatively common structural form in construction engineering. It has light weight and good rigidity. It has strong deformation ability, simple and convenient construction, and is widely used in large workshops, venues, super high-rises and other fields. The technical performance is also remarkable, with good heat preservation and energy saving technology, fire protection technology and sound insulation technology. Let's take a closer look below.

(1) First of all, let's learn about the thermal insulation and energy saving technology of steel structure. In order to achieve the effect of thermal insulation, the thermal insulation materials used in the exterior walls and roofs of buildings can be used for a long time and Keep warm. In addition to filling the glass fiber mesh between the wall columns, the steel structure building will paste a layer of thermal insulation material on the outside of the wall, which effectively cuts off the thermal bridge from the wall column to the outer wall panel; the joists between floors are filled with glass Fibers to reduce heat transfer through floors; glass fibers are filled between the wall columns of all interior walls to reduce heat transfer between household walls.

(2) Fire protection technology One of the most critical issues in light steel structure is the application of fire protection technology. The fire resistance level of light steel structure residential buildings is four. The light steel structure residential building is covered with fireproof gypsum board on both sides of the wall and the ceiling of the floor. For ordinary fire walls and sub-family walls, 25.4 mm thick (1 inch) gypsum board is used to maintain the fire protection requirements of 1 hour. Fiberglass filling between wall studs and floor joists also plays an active maintenance role with regard to fire protection and heat transfer.

(3) Sound insulation technology The light steel structure is filled with glass wool between the inner and outer walls and the joists of the floor, which effectively prevents the audio parts that pass through the air. The following structural treatment: for the household wall, two wall columns are used to form a second wall with an intermediate space; for the small keel used for the fixed gypsum board for the ceiling, an elastic structure with a small cut groove is used to effectively reduce the floor space. solid-state sound propagation.

Nowadays, the adoption of prefab houses in container frame industry is quite common.

Lida Group will continue to bring our industry nuances of style and approaches to prefab houses which are consistent with our evolving aspirations.

Lida Group deems prefab houses as evolutionary rather than revolutionary. We've always had these 'social commerce' marketplaces in some form.
