Problems solved by technology

[0002] The floor system of the existing prefabricated house structure can be divided into cast-in-situ concrete floor, profiled steel plate composite floor, steel bar truss composite floor, and concrete laminated slab floor. Templates, steel bars, scaffolding, etc.), there are many operators on site, the construction speed is slow, large environmental pollution is generated, the cost of safety protection is high, and the energy saving and environmental protection indicators are low
[0003] The porous prefabricated panels used in the past have been banned because they are easy to fall off and collapse under the horizontal action of earthquakes and winds.

Embodiment Construction

[0028] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0029] see Figure 1-4 , The invention discloses a fully prefabricated concrete floor slab for building.

[0030] Preferably, the installation process of the fully prefabricated concrete floor slab includes:

[0031] A. Install steel structural columns and U-shaped steel beams 102 (including concrete beams).

[0032] B. Install the fully prefabricated concrete floor slab 101 on the U-shaped steel beam 102 .

[0033] C. When there is a steel plate shear wall, place the section steel 106 (such as channel steel, angle steel, etc.) embedded in the fully prefabricated concrete floor 101 on the angle steel 107, and weld and fix it with the steel plate shear wall 105 at the same time. The steel plate shear wall 105 is welded and fixed.

[0034] D. Post-pouring concrete 103 between beam strip concrete and slab seams.

[0035] E. in Figure 5 In...

Abstract

The invention relates to a prefabricated concrete floorslab for building. The floor work on the construction site is concentrated in the factory, and the work of pouring concrete on site is only back strips among a few plates. The prefabricated concrete floorslab extends into a recurved anchorage beam in a U-shaped beam through a top rebar and is connected with the steel plate shear wall structure through the connection structure in the plate, which solves the problems of collapse of the prefabricated plate, and transfer of the horizontal force, and realizes hogging moment on the top generated by loading in the bearing stage, and no cracking of the floorslab top after the deformation of the floorslab is guaranteed.

Description

technical field [0001] The invention relates to a prefabricated component of a building floor system, in particular to a fully prefabricated concrete floor slab for a building. Background technique [0002] The floor system of the existing prefabricated house structure can be divided into cast-in-situ concrete floor, profiled steel plate composite floor, steel bar truss composite floor, and concrete laminated slab floor. Templates, steel bars, scaffolding, etc.), there are many operators on site, the construction speed is slow, large environmental pollution is generated, the cost of safety protection is high, and the indicators of energy conservation and environmental protection are low. [0003] The porous prefabricated panels used in the past have been banned because they are easy to fall off and collapse under the horizontal action of earthquakes and winds. [0004] In addition to meeting the force and structural integrity of the prefabricated floor system, it should als...
