Laminated plate

Abstract

The present invention relates to a laminated slab. It includes reinforced concrete and laminated inverted T-shaped slab. Said laminated inverted T-shaped slab is set in the bottom portion of floor slab. Said laminated inverted T-shaped slab includes base slab and longitudinal rib, the longitudinal rib is set on the base slab. It is characterized by that on the base slab at least one transverse slab slot is set, said slab slot is set at two sides of said longitudinal rib, and on the longitudinal rib at least one, two or three slot-connecting holes are set, and can be used for connecting with slab slot. The invented laminated slab is applicable to cast-in-situ reinforced concrete or prestressed reinforced concrete laminated floor, roof, wall body, foundation bedplate and bridge, etc.

Description

(1) Technical field [0001] The invention relates to a laminated board. (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-place concrete, which aff...

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.
