Lamination plate

Abstract

The present invention relates to a kind of laminated plate. It includes reinforced concrete and laminated inverted T-shaped plate, the laminated inverted T-shaped plate is placed in the bottom portion of floor slab. The laminated inverted T-shaped plate includes baseplate and longitudinal rib, said longitudinal rib is set on the baseplate, and its is characterized by that on the baseplate at least one transverse recessed groove is set, at least one side of said longitudinal rib has a plate transverse groove, at least one, two and three groove-connecting holes are communicated with the plate transverse groove, so that the cast-in-situ concrete can be fed into recessed groove, and can be solidified and hardened, the laminated inverted T-shaped plate and cast-in-situ concrete structure can be firmly combined together so as to ensure quality of laminated plate. It is applicable to various floor, roof, wall body, foundation bedplate and bridge.

Description

(1) Technical field [0001] The invention relates to a laminated board. (2) Background technology [0002] At present, the domestically used reinforced concrete floor slabs include cast-in-place floor slabs and pre-cast floor slabs. The cast-in-place floor slab has good integrity, but requires on-site formwork and then pouring the concrete. The construction period is difficult, the formwork loss is large, and the cost is high. Precast floor slabs do not need on-site Formwork, short construction period, low cost, but prefabricated components are heavy, difficult to hoist, component splicing parts are prone to cracks, poor integrity, such as the patent number ZL0322765.2, the name is a kind of reinforced concrete assembly floor patent, which discloses A prefabricated reinforced concrete component. The prefabricated component is composed of slabs and ribs. The ribs have holes through which steel bars are inserted. The thickness of this slab is large, which greatly reduces the effecti...

AI Technical Summary

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 is poor. For example, the patent number is ZL0322765. 2. The patent titled a reinforced concrete assembled floor slab discloses a reinforced concrete prefabricated component. The prefabricated component is composed of plates and ribs, and the ribs have holes for piercing steel bars. The effective height of the steel bars in the pouring concrete is greatly reduced, which affects the two-way force balance of the floor slab, and it is difficult to form an equivalent two-way slab, etc.
