Description

Technical Field

[0001] The utility model relates to the technical field of anti-leakage of laminated plates, and more specifically, to an anti-leakage structure for prefabricated roof laminated plates. Background Technique

[0002] A composite floor slab is an assembled monolithic floor slab formed by laminating a precast slab at the bottom and a cast-in-place reinforced concrete layer at the upper layer. The composite floor slab has good integrity, high stiffness, can save formwork, and the upper and lower surfaces of the slab are flat, which is convenient for the decoration of the finishing layer, and is suitable for high-rise buildings and large-span buildings with high requirements for overall stiffness.

[0003] The patent document with the publication number of CN219548123U discloses an anti-leakage connection structure for a composite floor slab, which includes a composite floor slab body and a wall. A connecting piece is arranged at the bottom of the composite floor slab body. A screw penetrates through one side of the connecting piece, and the screw is threadedly connected with the wall. The top of the connecting piece abuts against the top of the composite floor slab body. A convex strip is fixedly connected to the bottom of the composite floor slab body, and a groove matching the convex strip is opened at the top of the connecting piece; in this anti-leakage connection structure for a composite floor slab, the composite floor slab body and the wall are connected through a connecting piece, which can make the connection between the composite floor slab body and the wall more firm. Through the convex strip fixedly connected to the bottom of the composite floor slab body and the groove opened at the top of the connecting piece, the convex strip can be clamped into the groove. When construction workers pour concrete onto the composite floor slab, through the clamping between the convex strip and the groove, a better anti-leakage effect can be achieved. However, in the prior art, when pouring concrete onto the composite floor slab, the concrete flows into the through holes. After the composite floor slab is installed, the through holes are located on the wall, and the water in the concrete directly contacts the wall, and still has a high probability of flowing out from the joint between the wall and the composite floor slab; moreover, if there is moisture between the connection structure and the composite floor slab, it cannot be collected and discharged.

[0014] Further, a groove is formed in the connecting member along the length direction, and a rib adapted to the groove is fixedly connected to the lower end surface of the laminated slab body.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

Specific implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Specific embodiments:

[0027] Such as Figures 1 - 6As shown in the figure, a leak-proof structure for an assembled roof composite slab includes a connecting member 3 fitted at the joint of a wall 1 and a composite slab body 2. A screw 4 passes through the connecting member 3, and the screw 4 is threadedly connected to the wall 1. A water stop strip (not shown in the figure) is provided between the gap between the connecting member 3 and the wall 1. On one side of the connecting member 3 that fits against the composite slab body 2, a water collecting groove 31 is provided. The water collecting groove 31 is arranged along the length direction of the connecting member 3. On one side of the connecting member 3 that fits against the composite slab body 2, a plurality of water draining grooves 32 communicating with the water collecting groove 31 are also provided. In this embodiment, two water draining grooves 32 are provided. A vertical rod 5 is fixedly connected inside the water draining groove 32. A positioning rod 6 is fixedly connected to the upper end of the vertical rod 5. A through hole 21 adapted to the vertical rod 5 is provided on the composite slab body 2. The through hole 21 and the vertical rod 5 have the same diameter. The diameter of the positioning rod 6 is smaller than the diameters of the vertical rod 5 and the through hole 21. After the composite slab body 2 is installed, the upper end surface of the positioning rod 6 is flush with the upper end surface of the composite slab body 2. When installing the composite slab body 2, first, the connecting member 3 is installed on the wall 1 through the screw 4. Since the diameter of the positioning rod 6 is smaller than the diameter of the through hole 21, it is convenient for the staff to put the through hole 21 on the positioning rod 6 when installing the composite slab body 2 for preliminary positioning of the composite slab body 2. During the process of lowering the composite slab body 2, the through hole 21 is put on the vertical rod 5. The vertical rod 5 and the through hole 21 have the same diameter, and the through hole 21 closes the through hole 21. When pouring concrete on the composite slab body 2, the concrete flows into the through hole 21, making the connection between the composite slab body 2 and the connecting member 3 (the positioning rod 6 and the vertical rod 5) tighter. The vertical rod 5 and the positioning rod 6 are arranged on the connecting member 3, and the connection is more firm. If the water in the concrete flows in through the gap between the vertical rod 5 and the through hole 21, the water will enter the water draining groove 32 and then enter the water collecting groove 31 from the water draining groove 32; the water in the gap between the composite slab body 2 and the wall 1 enters the gap between the connecting member 3 and the composite slab body 2 and then enters the water collecting groove 31 for collection.

[0028] As Figures 1 - 6 shown, first inclined surfaces 7 are provided on the water collecting groove 31 along the vertical direction of the length direction of the connecting member 3, which helps the water between the connecting member 3 and the composite slab body 2 to enter the water collecting groove 31 for collection.

[0029] As Figures 1 - 6 shown, a drain hole 8 communicating with the connecting member 3 is provided on the bottom wall of the water collecting groove 31. A water stop plug 9 is inserted into the drain hole 8. A second inclined surface 10 with the lowest point of the inclined surface facing the adjacent drain hole 8 is provided on the bottom wall of the water collecting groove 31. After the concrete is poured, a container is prepared in advance below the drain hole 8. The water stop plug 9 is pulled out, and the water in the water collecting groove 31 is drained through the drain hole 8. After draining, sealant (such as polyurethane foam sealant) is added into the water collecting groove 31 through the drain hole 8 to fill the water collecting groove 31.

[0030] As Figures 1 - 6As shown in the figure, a drip line 11 is provided on the side of the connecting member 3 away from the laminated slab body 2. There are multiple drip lines 11. If the water in the water collecting tank 31 overflows, the drip line 11 helps to reduce the probability of water contacting the wall 1.

[0031] As Figures 1 - 6 shown in the figure, the cross-section of the connecting member 3 is L-shaped, and a plurality of reinforcing ribs 13 are fixedly connected inside the opening to enhance the support strength of the connecting member 3. By providing the connecting member 3, the connection stability between the laminated slab body 2 and the wall 1 after pouring can be improved.

[0032] As Figures 1 - 6 shown in the figure, a groove 33 is provided on the connecting member 3 along the length direction, and a rib 12 adapted to the groove 33 is fixedly connected to the lower end surface of the laminated slab body 2. After the laminated slab body 2 is installed, the rib 12 is inserted into the groove 33, which can play a certain anti-leakage effect and improve the connection stability between the laminated slab body 2 and the connecting member 3.

[0033] The slopes of the first inclined surface 7 and the second inclined surface 10 are at least 3%.

[0034] The working principle of an anti-leakage structure for an assembled roof laminated slab in this embodiment is as follows: When pouring concrete on the laminated slab body 2, if the water in the concrete flows into the through hole 21 through the gap between the vertical rod 5 and the through hole 21, the water will enter the water drainage groove 32 and then enter the water collecting tank 31 from the water drainage groove 32; the water in the gap between the laminated slab body 2 and the wall 1 enters the gap between the connecting member 3 and the laminated slab body 2, and then enters the water collecting tank 31 for collection; after the concrete is poured, a container is prepared in advance below the drainage hole 8, the water stop plug 9 is pulled out, and the water in the water collecting tank 31 is discharged through the drainage hole 8. After the drainage is completed, caulking agent is added to the water collecting tank 31 through the drainage hole 8 to fill the water collecting tank 31.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
