Abstract
Description
Technical Field
[0001] This utility model relates to the field of civil engineering construction technology, and in particular to a water control structure that combines a horizontal tongue and groove joint of a basement exterior wall with a drainage floor. Background Technology
[0002] In the traditional construction of basement waterproofing, the exterior walls are often poured to a height of 300mm-500mm during the construction of the basement slab, and steel plate waterstops are installed. Due to the high height of the formwork, the difficulty of reinforcement, and the slow construction speed of the traditional method, the formwork is prone to bursting during the vibration of the poured concrete. The quality of the upturned concrete is difficult to guarantee, and the structural self-waterproofing can only rely on the steel plate waterstop to prevent leakage. In this case, the formwork is difficult to install, and it is difficult to form the upturned joint and the base slab in one go. The construction progress is slow, the self-waterproofing effect is poor, and there are quality and safety hazards of water seepage in the exterior walls later. In this case, the water seeping from the exterior walls can easily flow from the construction joints to the floor surface, making the floor surface smooth and damp, which is prone to moisture and mold growth. Utility Model Content
[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a water control structure that combines the horizontal tongue and groove joint of the basement exterior wall with the drainage floor, which can effectively waterproof and also effectively drain water seepage generated by the later construction joints, thus avoiding dampness and mold on the basement floor.
[0004] This utility model is achieved by the following technical solution:

The construction joint tongue-and-groove formwork structure includes a water-stop steel plate, a steel formwork, and a concrete base slab. The steel formwork is vertically mounted on the concrete base slab, with a water-stop steel plate in the middle. The upper end of the steel formwork is configured with an upward-facing tongue-and-groove joint, forming the construction joint tongue-and-groove formwork structure. The drainage floor structure includes a PVC drainage pipe, a concrete surface layer, a double-layer membrane isolation layer, a bluestone filter layer, and a drainage ditch. The bluestone filter layer, the double-layer membrane isolation layer, and the concrete surface layer are sequentially arranged on the concrete base slab. The PVC drainage pipe is embedded in the bluestone filter layer. A drainage ditch is provided on the concrete base slab of the basement, and the outlet of the PVC drainage pipe is connected to the drainage ditch. The basement exterior wall formed by the construction joint tongue-and-groove formwork structure is flush with the edge of the drainage floor structure.
[0006] Furthermore, the drainage floor structure also includes a waterproof concrete raft slab; the waterproof concrete raft slab is set on a concrete base slab located on the basement floor; the bluestone filter layer and drainage ditch are both set on the upper surface of the waterproof concrete raft slab.
[0007] Furthermore, concrete curbs are provided on both sides of the drainage ditch; one end of the PVC drainage pipe is placed in the bluestone filter layer and a filter screen is provided at the port, while the other end passes through the concrete curb and connects to the drainage ditch.

The construction joint tongue-and-groove formwork structure includes a water-stop steel plate 4, a steel formwork 6, and a concrete base slab 1. The steel formwork 6 is vertically mounted on the concrete base slab 1, with a water-stop steel plate 4 positioned in the middle of the formwork 6. The upper end of the steel formwork 6 is configured as an upward-facing tongue-and-groove joint 7, forming the construction joint tongue-and-groove formwork structure. The drainage floor structure includes a PVC drainage pipe 8, a concrete surface layer 11, a double-layer membrane isolation layer 12, a bluestone filter layer 13, and a drainage ditch 15. A bluestone filter layer 13, a double-layer membrane isolation layer 12, and a concrete surface layer 11 are sequentially arranged on the concrete base slab 1. The bluestone filter layer 13 and the concrete surface layer 11 are 100mm thick, and the double-layer membrane isolation layer 12 is 2mm thick to prevent water seepage and dampness from causing the basement floor surface to become damp. The PVC drainage pipe 8 is pre-embedded in the bluestone filter layer 13. A drainage ditch 15 is provided on the concrete base slab 1 of the basement, and the outlet of the PVC drainage pipe 8 is connected to the drainage ditch 15. The basement exterior wall formed by the construction joint tongue-and-groove formwork structure is attached to the edge of the drainage floor structure. This utility model adopts a construction structure that combines a horizontal construction joint tongue-and-groove formwork structure with a drainage floor structure for basement exterior walls. This not only makes formwork hoisting more convenient and ensures that the upward-turned tongue-and-groove 7 is formed in one step with the concrete base slab 1, but also extends the seepage path, significantly improves the self-waterproofing effect of the structure, improves project quality, and speeds up construction progress. Through the drainage floor structure, water seeping from the basement exterior walls can be guided to the drainage ditch 15 through the drainage pipe 8, keeping the ground dry and preventing the growth of moisture and mold.

The bluestone filter layer 13 can ensure that seepage water can flow from the PVC drainage pipe 8 into the drainage ditch 15, while the waterproof concrete raft slab 14 prevents seepage water from seeping into the floor slab below, thus improving the waterproof performance.
[0023] As a preferred embodiment, such as Figure 1 and Figure 2 As shown, concrete curbs 9 are provided on both sides of the drainage ditch 15 to increase the waterproof effect; one end of the PVC drainage pipe 8 is set in the bluestone filter layer 13 and a filter screen 10 is provided at the port, and the other end passes through the concrete curb 9 and connects to the drainage ditch 15, which can prevent the PVC drainage pipe 8 from being blocked.
[0024] As a preferred embodiment, such as Figure 1 and Figure 3 As shown, the construction joint tongue-and-groove formwork structure is equipped with external wall horizontal reinforcement 2 and external wall vertical reinforcement 3, and the external wall horizontal reinforcement 2 is located between the steel formwork 6 and the external wall vertical reinforcement 3. Figure 1 and Figure 5 As shown, the side of the steel formwork 6 is tied to the vertical steel reinforcement 3 of the basement exterior wall by passing through the opening 61 of the steel formwork with tie wire. The water-stop steel plate 4 is vertically welded to the vertical steel reinforcement 3 of the exterior wall by fixing connecting bars 5, which ensures the stability of the structure.
[0025] As a preferred embodiment, such as Figure 6 As shown, the water-stop steel plate 4 includes a straight section 41 and an inclined section 42, thereby extending the waterproof path and significantly improving the self-waterproofing effect of the structure.
