Folding inverted T shaped plate

Abstract

A folding inverted T-shaped plate includes below floor (1), longitudinal ribs (2), and longitudinal ribs (2) setting on the motherboard (1). It is characterized that it has at least one horizontal slot (3) on below board (1). Thus, the Inverted T-shaped plate longitudinal stiffness is great, which is difficult to break or deformation, and is advantageous for installation of the support on the inverted T-shaped plate, fully guarantee the safety of construction, reduce wear and tear cost savings, and by setting up horizontal slot, folding inverted T-shaped plate and the combination of cast-in-place concrete. Cast-in-place concrete into the slot condensation sclerosis, folding inverted T-shaped plate and cast-in-place concrete structure firmly bonded to composite solid riveting, difficult to crack, fully guarantee the quality of the composite plate, so as to achieve the purpose of this invention. It is applicable to the cast-in-place reinforced concrete or preparing dint reinforced concrete composite floor, roof, walls, foundation floor and bridge infrastructure use, particularly applicable to the use of composite floor.

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...

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.
