DETAILED DESCRIPTION

[0023] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0024] like Figure 1-Figure 4 As shown, a basement floor steel lattice column waterproof structure of the utility model includes a concrete layer 1. The lattice column 2 is inserted into the concrete layer 1. Then, under the action of the protective component 5 and the water-stop component, the connection gap between each component 2 and the structural floor 4 can be made tighter, thereby improving the waterproof performance.

[0025] Specifically, a vertically arranged lattice column 2 is provided on the concrete layer 1 , and an insertion groove 3 for the lattice column 2 to be inserted and with the opening facing upward is opened on the concrete layer 1 , and the lattice column 2 is inserted into the insertion groove 3 through the structural bottom plate 4 .

[0026] A structural base plate 4 is provided above the lattice column 2. The structural base plate 4 is provided with plugging holes which are transparent from top to bottom and for the lattice column 2 to be plugged in. The lattice column 2 can pass through the structural base plate 4 so that the lattice column 2 and the structural base plate 4 are connected. After the lattice column 2 passes through the structural base plate 4, the protective component 5 can be applied to the connection between the lattice column 2 and the structural base plate 4.

[0027] In order to improve the waterproof performance, in this embodiment, a protective component 5 is provided between the concrete layer 1 and the structural base plate 4. In order to ensure the waterproof performance of the connection gap between the lattice column 2 and the structural base plate 4 and prevent moisture penetration from causing corrosion or other damage, the protective component 5 is applied to the lower side of the structural base plate 4, so that the overall waterproof effect can be improved. In addition, the protective component 5 can also increase the durability of the structure and extend the service life of the building. The protective component 5 includes a waterproof protective layer 501 and a cement-based penetrating crystalline waterproof coating layer 502. In this embodiment, the waterproof protective layer 501 can be either a positive corner waterproof layer or a negative corner waterproof layer, or a combination of a positive corner waterproof layer and a negative corner waterproof layer. The waterproof protective layer 501 is applied on the upper side of the concrete layer 1, and the cement-based penetrating crystalline waterproof coating layer 502 is applied on the upper side of the waterproof protective layer 501. During the application process, the cement-based penetrating crystalline waterproof coating layer 502 is covered on the lattice column 2 and the structural base plate 4, so that the connection seam between the lattice column 2 and the structural base plate 4 can be closed to improve the waterproof effect.

[0028] The cement-based penetrating crystalline waterproof coating layer 502 in this embodiment has strong adaptability and is compatible with other materials. After being applied, it can improve the density of concrete and reduce its own shrinkage and cracking.

[0029] The waterproof protective layer 501 is composed of two layers and is laid up and down. A waterproof roll material 7 is arranged inside the waterproof protective layer 501. The cement-based penetrating crystalline waterproof coating layer 502 overlaps the waterproof roll material 7. By laying the roll material 7, water penetration can be prevented, thereby protecting the structural safety and use function of the building.

[0030] The cement-based penetrating crystalline waterproof coating layer 502 is spread on the inside of the lattice column 2 to improve the waterproof effect of the lattice column 2 .

[0031] In order to prevent moisture from seeping out from the connection between the lattice column 2 and the structural base plate 4, in the present embodiment, a water-stop assembly is fixedly connected between the lattice column 2 and the structural base plate 4. The water-stop assembly includes a clamping assembly 601 and a square plate 602. There are two clamping assemblies 601, which are arranged opposite to each other. After the lattice column 2 is inserted into the concrete layer 1, the clamping assembly 601 can be welded to the lattice column 2.

[0032] The square plate 602 and the clamping assembly 601 are both fixed in the lattice column 2 to prevent moisture from seeping out from the junction between the lattice column 2 and the structural bottom plate 4. When the square plate 602 and the clamping assembly 601 are welded to the lattice column 2, moisture can be prevented from seeping out from the connection between the lattice column 2 and the structural bottom plate 4, thereby ensuring the waterproof performance of the structure.

[0033] Each clamping assembly 601 includes an angle steel 6011 and a blocking plate 6012. There are two angle steels 6011 that are symmetrically arranged, and the blocking plate 6012 is a U-shaped structure.

[0034] The two angle steels 6011 are both fixedly connected to the blocking plate 6012, and the angle steel 6011 is fixedly connected to the lattice column 2, and the joint between the waterproof membrane and the angle steel 6011 is sealed with a sealant.

[0035] The two blocking plates 6012 are spliced ​​together to form a water stop plate structure.

[0036] The protection component 5 and the water-stop component cooperate with each other to prevent water seepage at the contact joint between the lattice column 2 and the structural bottom plate 4 .

[0037] Working principle: Surface cleaning: First, the surface of the lattice column 2 needs to be thoroughly cleaned to remove oil, dust, loose objects, etc., to ensure that the surface is clean, solid, and free of cracks and holes.

[0038] Install the water-stop assembly: install the square plate 602 inside the lattice column 2, and install the clamping assembly 601 on the outer wall of the lattice column 2. The thickness and width of the blocking plate 6012 should meet the design requirements and must be fully welded to the lattice column plate surface. The height of the blocking plate 6012 should be located in the middle of the thickness of the structural base plate 4.

[0039] Welding operation: Weld a blocking plate 6012 on the outer wall of the lattice column 2 through the central position of the structural bottom plate 4, and weld a square plate 602 inside the inner wall.

[0040] Sealing treatment: Apply the waterproof protective layer 501 evenly on the surface and surrounding of the lattice column 2. After the waterproof protective layer 501 is dry, lay the waterproof membrane 7 on the waterproof protective layer 501 and the waterproof membrane 7 to the root of the lattice column 2. Then, use sealant to seal the joint between the waterproof membrane 7 and the angle steel 6011. Then, apply the cement-based penetrating crystalline waterproof coating layer 502 on the waterproof membrane 7 to enhance the waterproof effect. The end of the waterproof membrane 7 is overlapped with the cement-based penetrating crystalline waterproof coating layer 502.

[0041] Before pouring concrete, the structural base plate 4 and the lattice column 2 are processed and the base plate reinforcement is tied.

[0042] Concrete pouring: Finally pour the concrete to ensure that the concrete strength and waterproof performance meet the standards.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is limited by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
