Background

The fabricated building is a building fabricated by assembling factory-prefabricated components on a construction site, and is rapidly popularized all over the world since the sixties of the twentieth century because of the advantages of high construction speed, low production cost, small seasonal influence and the like. The bearing wall (also called shear wall) is an important component of an assembled building, and is mainly used for bearing horizontal load and vertical load (gravity) caused by wind load or vibration and preventing the shearing (shearing) damage of a building structure. At present, reinforced concrete slabs are mostly adopted for load-bearing walls in fabricated buildings, for example, external wall panels are generally reinforced concrete composite boards with heat insulation layers, and the requirements of light wall boards are difficult to meet due to the large weight of the external wall panels; meanwhile, the wall body of the existing reinforced concrete plate structure also has the problem that the heat-insulating layer is easy to fall off; in addition, in order to make the cement mortar easily hung on the surface of the wall body, a calcium silicate board is also needed to be paved on the wall body.

Disclosure of Invention

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a prefabricated heat-insulating load-bearing wallboard frame structure comprises a reinforcing steel bar net piece, a lacing wire, an extruded sheet and a ribbed expansion net; the reinforcing mesh is of a grid structure formed by welding a plurality of longitudinally and transversely crossed reinforcing steel bars; the tie bars are arranged in a plurality of groups in parallel, vertically penetrate through the grid pores of the steel bar net piece, and are welded and fixed with the steel bar net piece to form a supporting framework; the ribbed expansion net is arranged on two sides of the reinforcing mesh sheet and fixed in a welding mode with two ends of the lacing wires, and the inner side of the ribbed expansion net is provided with an extruded sheet.

In the frame structure of the prefabricated heat-insulation load-bearing wallboard, the extruded sheet is a polystyrene rigid foam plastic board added with heat-insulation and flame-retardant materials.

According to the prefabricated heat-insulation load-bearing wallboard frame structure, the reinforcing mesh is located in the middle of the wall body frame, the longitudinal reinforcing steel bars and the transverse reinforcing steel bars are arranged at certain intervals and form right angles with each other, and the longitudinal reinforcing steel bars and the transverse reinforcing steel bars are welded and fixed at the intersection points.

According to the frame structure of the prefabricated heat-insulation bearing wallboard, the ribbed expansion net is made of pre-galvanized strip steel or 304 stainless steel, the steel strip is formed into a steel plate net through a steel strip cutting, expanding and drawing process, reinforcing ribs are uniformly arranged on the net surface of the steel plate net, and the distance between every two adjacent reinforcing ribs is not more than 110 mm.

The utility model relates to a prefabricated heat preservation bearing wall panel frame construction, it forms frame construction's support chassis with the lacing wire welding that reinforcing bar net piece and perpendicular passed reinforcing bar net piece to at lacing wire both ends fixed assembly extruded sheet and have muscle expansion net to form hollow panel frame, consequently can be at the job site with a plurality of panel frame attach as an organic whole after, the bearing wall body of prefabricated building is found to the pouring foaming concrete in its hollow structure. The extruded sheet of the utility model adopts the material of polystyrene hard foam plastic board, not only has the functions of heat preservation and flame retardance, but also can be matched with a ribbed expansion net to prevent the frame structure from being expanded by grouting pressure in the pouring process; the utility model discloses set up the muscle expansion net in the extruded sheet outside, strengthened frame construction's intensity on the one hand, its wire side structure of on the other hand more is favorable to wall body surface to hang cement mortar. Therefore, the utility model discloses not only satisfied assembled building wall lightweight requirement, still solved the heat preservation and drop and be difficult for hanging the problem of cement mortar.
