Description

Technical Field

[0001] This utility model relates to the field of floor slab technology, and in particular to a leak-proof floor slab. Background Technology

[0002] In the construction field, composite floor slab technology is widely used for the reinforcement and expansion of building structures. However, in practical applications, since the adjacent floor slabs are simply laid on the frame, the adjacent floor slabs cannot be sealed to a high degree, resulting in large gaps between the precast slabs and frequent leakage. This not only reduces the structural strength of the building, but also affects its service life.

[0003] Therefore, how to quickly and effectively solve the problem of leakage in composite floor slab structures has become a technical challenge to be solved in this field. To this end, this application proposes a leak-proof floor slab. Utility Model Content

A first U-shaped plate and a second U-shaped plate are integrally formed and connected to each other on the side of the two precast slabs that are close to each other. Multiple bolts are connected through the first U-shaped plate and the second U-shaped plate on the side that are close to each other. The first U-shaped plate and the second U-shaped plate are fixedly connected to each other by bolts. An extension strip is integrally formed and connected to the top of the side of the second U-shaped plate that is close to the first U-shaped plate. A rubber pad is filled between the extension strip and the first U-shaped plate.

[0006] Preferably, the first U-shaped plate and the second U-shaped plate are integrally formed and connected on their respective sides that are close to each other, with the first protrusion located above the second protrusion.

[0007] Preferably, the first U-shaped plate and the second U-shaped plate are respectively provided with a first groove and a second groove on the side that are close to each other. The first groove is located above the second protrusion, and the second groove is located below the first protrusion. The first protrusion and the second protrusion are respectively adapted to be inserted into the first groove and the second groove.

[0008] Preferably, the first U-shaped plate and the second U-shaped plate are provided with multiple bolt holes on the side that are close to each other, and two adjacent bolt holes on the left and right are connected to each other, and the bolts pass through the bolt holes.

[0010] Compared with related technologies, the waterproof floor slab provided by this utility model has the following beneficial effects:

[0011] By integrally forming and connecting the first U-shaped plate and the second U-shaped plate on both sides of the precast slab, and fastening the first U-shaped plate and the second U-shaped plate with bolts, and with the cooperation of the first protrusion, the first groove, the second protrusion, the second groove, the extension strip and the rubber pad, the first U-shaped plate and the second U-shaped plate are highly sealed.

[0017] Implementation examples, by Figure 1-4 The present invention comprises two precast slabs 1 adjacent to each other. A first U-shaped plate 2 and a second U-shaped plate 3 are integrally formed and connected to each other on the side of the two precast slabs 1 that are close to each other. A plurality of bolts 10 are connected through the first U-shaped plate 2 and the second U-shaped plate 3 on the side of the two precast slabs 10. The first U-shaped plate 2 and the second U-shaped plate 3 are fixedly connected to each other by bolts 10. An extension strip 4 is integrally formed and connected to the top of the side of the second U-shaped plate 3 that is close to the first U-shaped plate 2. A rubber gasket 5 is filled between the extension strip 4 and the first U-shaped plate 2. The extension strip 4 presses on the top of the first U-shaped plate 2, and there is also a rubber gasket 5 between the extension strip 4 and the first U-shaped plate 2, which effectively improves the sealing performance.

[0018] The first U-shaped plate 2 and the second U-shaped plate 3 are integrally formed and connected on their respective sides. The first protrusion 8 and the first protrusion 6 are located above the second protrusion 8. The first groove 7 and the second groove 9 are respectively formed on their respective sides. The first groove 7 is located above the second protrusion 8 and the second groove 9 is located below the first protrusion 6. The first protrusion 6 and the second protrusion 8 are respectively adapted to be inserted into the first groove 7 and the second groove 9. The first protrusion 6 is inserted into the first groove 7 and the second protrusion 8 is inserted into the second groove 9, which further improves the anti-leakage function between the first U-shaped plate 2 and the second U-shaped plate 3.

[0019] Multiple bolt holes 12 are provided on the side of the first U-shaped plate 2 and the second U-shaped plate 3 that are close to each other, and two adjacent bolt holes 12 are connected to each other. The bolts 10 pass through the bolt holes 12 and are used to fasten the first U-shaped plate 2 and the second U-shaped plate 3 together, so that the gap between them is better sealed and the leakage prevention effect is improved.

[0020] Multiple reinforcing bar holes 13 are provided on both sides of the first U-shaped plate 2 and the second U-shaped plate 3. The bolt holes 12 and the reinforcing bar holes 13 are distributed alternately. A connecting reinforcing bar 11 is connected through the inside of the reinforcing bar hole 13. The connecting reinforcing bar 11 passes through the first U-shaped plate 2 and the second U-shaped plate 3, which can improve the firmness between adjacent precast plates 1 when the concrete is finally poured.

[0021] Working principle:

[0022] When prefabricating the precast slab 1, the first U-shaped plate 2 and the second U-shaped plate 3 are integrally prefabricated on both sides of the precast slab 1. When assembling the two precast slabs 1, the first U-shaped plate 2 and the second U-shaped plate 3 between the two precast slabs 1 will be fitted together. It is only necessary to align and assemble the first protrusion 6 and the first groove 7, the second protrusion 8 and the second groove 9, and then use bolts 10 to fasten the first U-shaped plate 2 and the second U-shaped plate 3. At this time, the extension strip 4 presses on the top of the side of the first U-shaped plate 2 near the second U-shaped plate 3, and a rubber gasket 5 is filled between the first U-shaped plate 2 and the extension strip 4 to improve the sealing. At this time, the first U-shaped plate 2 and the second U-shaped plate 3 have very good sealing, thus achieving the effect of preventing leakage. As for the connecting steel bar 11 passing through the first U-shaped plate 2 and the second U-shaped plate 3, it can improve the firmness between the two adjacent precast slabs 1 after the concrete is poured.
