Problems solved by technology

[0002] At present, the reinforced concrete floor slabs used in China include cast-in-place floor slabs and prefabricated floor slabs. The difficulty is high, the loss of the formwork is large, and the cost is high. The prefabricated floor does not require on-site formwork, the construction period is short, and the cost is low. However, the prefabricated components are heavy and difficult to hoist. Cracks are prone to occur at the splicing parts of the components, and the integrity

Embodiment Construction

[0092] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0093] As shown in the drawings, the present invention includes a bottom plate 1 and a longitudinal rib 2. The longitudinal rib 2 is arranged on the bottom plate 1. It is characterized in that there is at least one transverse groove 3 on the bottom plate 1, and at least one side of the longitudinal rib 2 has a plate transverse groove. Groove 4 has at least one, two, three connecting groove holes 5 and the horizontal groove 4 of the plate, and the top surface of the connecting groove holes 5 and the top surface of the base plate 1 are flat or high or low. In each accompanying drawing, 1 is a base plate, 2 is a longitudinal rib, 3 is a groove, 4 is a plate transverse groove, and 5 is a connecting groove hole 5. In the following accompanying drawings, those with the same numbering have the same description. As shown in Figure 1, the laminated inverted T-sh...

Abstract

Disclosed is a superposed reverse-T shaped board comprising bottom boards (1), longitudinal ribs (2) arranged on the bottom boards (1), characterized in that the bottom boards (3) are provided with at least one transverse grooves (5), at least one side of the longitudinal rib (2) is provided with a transverse plate groove (4) and at least one, two or three horizontal board grooves (4) connected by the groove-linking holes (5), the top of the groove-linking holes is at a same level, or higher or lower with the top of the bottom board (1). The invention can be applied to storied building roofings, house roofings, walls, foundation bedplates and bridges.

Description

(1) Technical field [0001] The invention relates to a superimposed inverted T-shaped plate. (2) Background technology [0002] At present, the reinforced concrete floor slabs used in China include cast-in-place floor slabs and prefabricated floor slabs. The cast-in-place floor slabs have good integrity, but they need to be molded on site, and then concrete is poured. The construction period is difficult, the loss of the formwork is large, and the cost is high. formwork, short construction period and low cost, but the prefabricated components are self-heavy, difficult to hoist, cracks are prone to occur at the splicing parts of the components, and the integrity is poor, such as the patent No. ZL0322765. A reinforced concrete prefabricated component. The prefabricated component is composed of slabs and ribs, and the ribs have holes for passing steel bars. The thickness of the slab is large, which greatly reduces the effective height of the steel bars placed in the cast-in-plac...
