Embodiment Construction

[0009] Below in conjunction with accompanying drawing, describe the specific embodiment of the present invention in detail:

[0010] Such as figure 1 As shown, the leak-proof prefabricated panel of the present invention includes: a panel body 1 and longitudinal reinforcement bars 2 and transverse reinforcement bars 3 poured in the panel body 1, the transverse reinforcement bars 3 rest on the longitudinal reinforcement bars 2, and the panel body 1 The side surfaces on both sides of the board are sloped, so that the cross-section of the board body 1 is a trapezoidal shape with a left-right symmetry and a narrow top and a wide bottom. mm.

[0011] After laying, the transverse steel bars 3 are firstly welded in one-to-one correspondence to form a welding portion 5 between the end surfaces of two corresponding transverse steel bars 3, and then fill the inverted space formed between two adjacent boards 1 with concrete. The triangular gap forms a junction 4 connecting two adjacent ...

Abstract

The invention discloses an anti-leakage precast slab, which can be used for lowering the labor intensity, improving the plugging effect and improving the anti-cracking and anti-vibration performance. The anti-leakage precast slab comprises a slab body, longitudinal reinforcing steel bars and lateral reinforcing steel bars, wherein the longitudinal reinforcing steel bars and the lateral reinforcing steel bars are cast in the slab body; two side surfaces of the slab body are both slopes; the cross section of the slab body is a bilateral-symmetry trapezoid with a narrow top and a wide bottom; the lateral reinforcing steel bars extend out of the slab body; and the end surface of the lateral reinforcing steel bar is far away from the lower edge end line of the trapezoid on the same side for 1.5-3mm. According to the anti-leakage precast slab disclosed by the invention, in the precast slab overlaying process, the lower edges of two adjacent precast slabs are guaranteed to be tightly close together, and the precast slabs are very convenient to overlay, thereby lowering the labor intensity, and improving the overlaying efficiency. In addition, an inverse-triangle gap formed by adjacent precast slabs can be used for greatly improving the plugging effect. In addition, the lateral reinforcing steel bars can be correspondingly welded together one by one so as to improve the anti-cracking and anti-vibration performance of the whole floor.

Description

technical field [0001] The invention relates to a prefabricated board, in particular to a leak-proof prefabricated board. Background technique [0002] The structure of the current prefabricated slab includes: a slab body and longitudinal reinforcement and transverse reinforcement cast in the slab body, and the cross section of the slab body is rectangular. When this kind of prefabricated slab is used to lay the floor, a straight seam will be formed between adjacent prefabricated slabs. Moreover, in order to facilitate sealing, this straight seam must be suitable, too large or too small, so it must be installed during the laying process. Continuous adjustment increases labor intensity and affects laying efficiency. In addition, the prefabricated panels are independent of each other, which makes the crack resistance and earthquake resistance of the entire floor poor. In addition, although after laying, the straight joints between adjacent prefabricated panels will be sealed...
