Problems solved by technology

Compared with cast-in-place slabs, prefabricated slabs have the advantages of convenient construction and low cost, but the strength of prefabricated slabs is lower than that of cast-in-place slabs, and because prefabricated slabs are strip-shaped, they need to be spliced ​​and formed and filled with cement or cement in the gaps during on-site construction. concrete
The strength of the existing prefabricated slab itself is low, and because the concrete in the gap is filled in the later stage, the strength of the joint of the prefabricated slab is low, and the joint of the prefabricated slab is prone to breakage during vibration, which affects the quality of the entire spliced ​​floor. strength

Embodiment 1

[0038] Such as Figure 1-Figure 3 As shown, the present invention is a kind of anti-seismic prefabricated slab for building, comprising pouring slab body 4, covering layer attached to the surface of pouring slab body 4, and internal frame arranged in pouring slab body 4; The internal frame includes two layers Relatively arranged steel bar frame, the steel bar frame includes a number of longitudinal steel bar 1 arranged in parallel and a number of horizontal steel bar 2 arranged in parallel at intervals, the longitudinal steel bar 1 is arranged along the length extension direction of the pouring plate body 4, and the horizontal steel bar 2 and the longitudinal steel bar 1 is vertically arranged, the two ends of the horizontal steel bar 2 respectively protrude from the surface of both sides of the pouring plate body 4, and the two ends of the longitudinal steel bar 1 respectively protrude from the two ends of the pouring plate body 4; the middle part of the pouring plate body 4 ...

Embodiment 2

[0066] The difference between this embodiment and Embodiment 1 is that: the transverse reinforcement rod 2 is arc-shaped, the arc-shaped openings of the transverse reinforcement rod 2 of the two-layer reinforcement frame are oppositely arranged, and the arc of the transverse reinforcement rod 2 is 3.05.

[0067] The concrete is made of the following raw materials in parts by weight: 350 parts by weight of cement, 103 parts by weight of water, 800 parts by weight of recycled concrete aggregate, 1.5 parts by weight of modified starch, 0.4 parts by weight of sugar retarder, and the amount of nylon fiber by weight It is 1 / 150 of the weight of concrete dosage.

Embodiment 3

[0069] The transverse reinforcing bar 2 is arc-shaped, and the arc-shaped openings of the transverse reinforcing bar 2 of the two-layer steel frame are oppositely arranged, and the arc of the transverse reinforcing bar 2 is 3.05.

[0070] The concrete is made of the following raw materials in parts by weight: 335 parts by weight of cement, 103 parts by weight of water, 763 parts by weight of recycled concrete aggregate, 1 part by weight of modified starch, and 0.33 parts by weight of sugar retarder.

Abstract

The invention discloses an anti-seismic prefabricated board for a building. The anti-seismic prefabricated board comprises a pouring board body (4), a covering layer attached to the surface of the pouring board body (4), and an internal frame arranged in the pouring board body (4); the internal frame comprises two layers of oppositely-arranged steel bar frameworks which each comprise a plurality of longitudinal steel bar rods (1) arranged in parallel and a plurality of transverse steel bar rods (2) arranged in parallel and at intervals, the longitudinal steel bar rods (1) are arranged in the length extension direction of the pouring board body (4), and the transverse steel bar rods (2) are perpendicular to the longitudinal steel bar rods (1). The anti-seismic prefabricated board has the advantages of being capable of overcoming the defects of the prior art and reasonable and novel in structure design.

Description

technical field [0001] The invention relates to an anti-seismic prefabricated panel for building and a manufacturing method thereof, belonging to the field of construction. Background technique [0002] Prefabricated slabs are concrete prefabricated parts produced and processed in the prefabricated field, which are directly transported to the construction site for installation. Now prefabricated panels are generally used as roof capping panels for multi-storey buildings. Compared with cast-in-place slabs, prefabricated slabs have the advantages of convenient construction and low cost, but the strength of prefabricated slabs is lower than that of cast-in-place slabs, and because prefabricated slabs are strip-shaped, they need to be spliced ​​and formed and filled with cement or cement in the gaps during on-site construction. concrete. The strength of the existing prefabricated slab itself is low, and because the concrete in the gap is filled in the later stage, the strength...
