Embodiment Construction

[0030] Attached below Figure 1~5 The specific implementation manner of the height-adjustable prefabricated concrete laminated floor slab of the present invention is described.

[0031] As shown in the drawings, a height-adjustable assembled prefabricated concrete laminated floor slab of the present invention includes angle steel 1 , soft material 2 , steel bar truss 3 , L-shaped screw rod 4 , concrete 5 and nut 6 .

[0032] Concrete 5 and steel bar truss 3 are poured together to form member A1, and steel bar truss 3 is distributed at the bottom of the prefabricated slab as stress reinforcement, and member A1 reserves holes along both sides of the beam direction during pouring; soft material 2 is pasted on the corner of angle steel 1 Component A2 is composed of one side of the short side, and angle steel 1 is slotted at the position corresponding to the hole of component A1; components A1 and A2 are both manufactured in the factory; before site hoisting, component A2 is placed...

Abstract

A height-adjustable fabricated concrete composite floor slab comprises angle steel, a flexible material, a steel bar truss, an L-shaped lead screw, concrete and nuts. A component A1 is poured throughthe concrete and the steel bar truss jointly. The flexible material is pasted on one side of the short edge of the angle steel to constitute a component A2, holes are reserved in the corresponding positions of the component A1 and the component A2, and the component A1 and the component A2 are manufactured in a factory. A vertical rod of the L-shaped lead screw on site penetrates through the holesin the component A1 and the component A2 and is screwed down through the nuts, and a cross rod is hung on the upper surface of a beam. The height of a prefabricated slab is adjusted by adjusting thenuts on the lead screw to ensure that the lower surfaces of all the floor slab bodies are flush, and the assembly problem caused by the uneven surfaces of the concrete components is solved. Part of the beam height is invisible through the connecting mode, and thus spatial arrangement of the structure is more flexible and more beautiful. The angle steel and the prefabricated slab serve as a bottomformwork, a gap is filled with the flexible material, and formwork erecting pouring of post-pour layers of the composite floor slab bodies is facilitated. Bonding force of new and old concrete layersis increased through the steel bar truss in the prefabricated slab, and the overall performance of the composite floor slab bodies is improved.

Description

technical field [0001] The invention belongs to the field of building structural components and is suitable for prefabricated concrete buildings. Background technique [0002] Precast concrete laminated slab refers to an assembled integral floor slab formed by superimposing the upper cast-in-place layer with precast concrete thin slabs at the bottom. This laminated floor slab has good integrity, high rigidity, and crack resistance Good, does not increase the consumption of steel bars, saves formwork, etc., and can be constructed in the form of prefabrication to the greatest extent, which represents the development direction of the national construction industrialization. The existing precast concrete laminated floor forms have the following shortcomings: [0003] 1) The laminated floor slab is placed on the beam through studs or bolts welded to the upper flange of the beam, and the entire beam height is exposed to the outside, which reduces the net height of the structural l...
