Has the advantages that:

1. the self weight of the traditional reinforced concrete floor per square meter is about 220 kilograms, and the self weight is larger. According to the relevant national regulations, the movable load of the residential floor is 200 kilograms per square meter. Half of the gravity borne by the traditional floor slab is from the self weight, and more than half of the material capacity is wasted in internal consumption. The groove bearing plate has the advantages that the weight per square meter is about 20 kilograms, the self weight is light, the groove bearing plate mainly bears the movable load generated in the using process, and the material function is reasonably exerted.

2. The groove bearing plate can be produced on a production line, realizes the industrialization of building products, greatly reduces the production cost, and simultaneously can reduce the use of high energy consumption materials such as cement, gravel and the like and reduce the pollution to the environment.

3. The groove is designed in a sinking mode, the end head of the groove is a blind end, two sides of a steel plate are flat in the design, and a force bearing edge can be manufactured by utilizing a production line in a rolling forming mode.

4. The sunken grooves on the two sides of the bearing edge can increase the rigidity of the bearing edge, enhance the deformation resistance of the bearing edge, ensure that the bearing edge is not unstable when stressed, and simultaneously can transmit the movable load in the middle of the two bearing edges to the bearing edge and then to the wall or the horizontal beam through the bearing edge.

When the groove is used as a floor slab, the groove is a blind hole groove, the length direction of the groove is perpendicular to the length direction of the bearing edge, and therefore, the floor load can be transferred. Secondly, the width of the groove type steel floor can be ensured to the maximum extent. The maximum width of the existing sheet steel specification is 1.25m, and the length can reach several hundred meters. The transverse arrangement of the grooves has small influence on the width in the transverse direction, so that the width of a single floor slab can be maximized.

8. Due to the lack of the structural theory of wall joints, the steel plate wall building has not realized breakthrough all the time. When the groove bearing plate is used as a wall body, horizontal assembly holes and right-angle assembly holes are arranged on the bearing edge, different combinations can be realized between the plane type groove bearing plates or between the plane type groove bearing plate and the right-angle type groove bearing plate through the horizontal assembly holes and the right-angle assembly holes, an L-shaped or T-shaped or cross-shaped node wall body is formed, the difficult problem of a wall body node connection structure is thoroughly solved, and the construction of a steel plate wall body building can be realized.

9. Through theoretical calculation and experiments, the optimal technical parameters of the bearing edge and the groove are determined as follows: the height of the bearing edge is 80-500mm, the depth of the groove is 15-70mm, the width of the groove is 30-180mm, the center distance of the groove is 70-360mm, and the thickness of the steel plate is 1.2-6.0 mm.

The butt joint holes on the bearing edges are symmetrically arranged in double rows or staggered in double rows, so that surface-to-surface connection can be formed during connection between the bearing edges, and the phenomenon that the connection surface is opened after the bearing edges are connected in a single row and stressed is avoided.

11. The end beam can be an integral end beam formed by bending a rectangular steel plate, and the integral rigidity is good. The end beam can be used as a connecting beam of a floor slab when the bending direction of the end beam is inward.

12. The utility model can form floor slabs through different angle combination of the groove bearing plates, can also form a linear or L-shaped or T-shaped or cross-shaped node wall body, can form buildings by self combination, does not need to additionally use members such as beams or columns, is extremely convenient to install, can be produced in large batch through a production line, reduces the cost, and has wide market prospect.
