Description

Technical Field

[0001] The utility model relates to a construction structure for preventing seepage at the joint of laminated plates, belonging to the technical field of laminated plate construction. Background Art

[0002] A laminated plate is an assembled monolithic floor slab formed by laminating a precast slab and a cast-in-place reinforced concrete layer. The laminated 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. It is suitable for high-rise buildings and large-span buildings with high requirements for overall stiffness.

[0003] CN218149158U discloses a construction structure for preventing seepage at the joint of laminated plates. In the comparative document, the U-shaped structural member is a waterproof pad made of asphalt waterproof coiled material, which is wrapped around one end of the precast slab, and only uses the waterproof performance of the conventional waterproof pad to achieve the anti-seepage effect. The long-term anti-seepage effect of this method is poor, so improvement is needed. Summary of the Utility Model

[0004] In order to solve the above problems existing in the prior art, the utility model provides a construction structure for preventing seepage at the joint of laminated plates, which can have a good anti-seepage effect.

[0005] The technical solution of the utility model is as follows:

[0006] A construction structure for preventing seepage at the joint of laminated plates includes two laminated plates. C-shaped connectors are预埋 at the connecting ends of the two laminated plates. The two C-shaped connectors are spliced at the joint of the laminated plates. Each of the two C-shaped connectors includes two integrally formed embedded end plates and a joint panel. The two embedded end plates are vertically connected to the joint panel to form a C shape. The two embedded end plates are embedded and fixed into the laminated plates. The two joint panels are adhesively connected. The connection gaps on the upper and lower sides of the two joint panels are both connected by full welding. Waterstop rubber strips are arranged on the upper and lower sides of the C-shaped connector and filled into the joint of the laminated plates. A fixing pressure plate is pressed and fixed outside the waterstop rubber strip.

[0007] Wherein, embedded bolts are fixedly arranged on the embedded end plates, and the fixing pressure plate is provided with mounting holes. The threaded ends of the embedded bolts extend out of the laminated plate through the mounting holes, and the embedded bolts press and fix the fixing pressure plate through locking nuts.

[0008] Wherein, one of the joint panels is provided with a positioning protrusion, and the other joint panel is provided with a positioning groove, and the positioning protrusion and the positioning groove are matched.

[0009] Wherein, the mounting holes are waist-shaped holes.

[0010] The utility model has the following beneficial effects:

[0011] The utility model achieves anti-seepage through a combination of technical means such as U-shaped connectors, embedded connections, and full-weld connections. The U-shaped connectors are embedded on one side of the precast slab to transfer the gap to the connection surface of the two connectors. By utilizing the stable waterproof effect of full welding and then realizing its sealing performance through the connection advantage of full welding, the anti-seepage effect at the joint of the laminated slab can be improved, as well as the long-term anti-seepage stability. At the same time, its durability is far superior to other waterproof materials. The anti-seepage structure of this application has excellent performance in terms of weather resistance, temperature resistance, durability, etc. BRIEF DESCRIPTION OF THE DRAWINGS
