Description

Technical Field

[0001] The utility model relates to the technical field of waterproofing of prefabricated stairs, in particular to a waterproof structure of a joint of a prefabricated staircase. Background Art

[0002] Stairs are components used for vertical transportation between floors in a building. They are used for transportation between floors and when there is a large height difference. At present, reinforced concrete stairs are the most commonly used. There are two construction methods for reinforced concrete stairs: cast-in-place and prefabricated assembly. Cast-in-place stairs have better rigidity, but the template consumption is large, the construction period is long, and manual grooves and roughening are required on the surface of the stairs, which is labor-intensive and generates serious sewage dust and noise.

[0003] The prefabricated stairs are prefabricated in the factory in advance and can be directly installed at the construction site. There is no need to set up formwork and water maintenance, which saves water resources and maintenance time, and is conducive to shortening the construction period. When the prefabricated stairs and the building wall are spliced, the prefabricated stairs and the building wall are usually sealed with sealant on the outside of the splicing seam to ensure the waterproofness of the splicing seam between the prefabricated stairs and the building wall. However, as the sealing effect of the sealant of this waterproof structure deteriorates over time, a small amount of water will still enter the wall, making it difficult to effectively waterproof. The waterproof performance is poor, which affects the quality of the splicing end of the prefabricated stairs and the building wall, thereby reducing the service life of the prefabricated stairs. Therefore, a waterproof structure for the splicing seam of prefabricated stairs is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-2The waterproof structure of the prefabricated stair joint in this embodiment includes a floor main body 1 and a prefabricated stair main body 2, and a waterproof structure 3 is provided on the top of the floor main body 1 and the prefabricated stair main body 2.

[0020] See also Figure 2-3 The waterproof structure 3 in this embodiment includes a waterproof board 31 arranged at the top of the floor body 1 and the prefabricated stair body 2. The waterproof board 31 includes an anti-slip layer 311, a wear-resistant layer 312, a corrosion-resistant layer 313, a waterproof coating 314, a waterproof membrane 315 and a base plate 316. The waterproof structure 3 also includes a connecting component arranged on the waterproof board 31 for connecting the floor body 1 and the prefabricated stair body 2.

[0021] Among them, the waterproof membrane 315 is fixed to the outside of the bottom plate 316, the waterproof coating 314 is fixed to the outside of the waterproof membrane 315, the corrosion-resistant layer 313 is fixed to the top of the waterproof membrane 315, the wear-resistant layer 312 is fixed to the top of the corrosion-resistant layer 313, the wear-resistant layer 312 is fixed to the top of the anti-slip layer 311, and the anti-slip layer 311, the wear-resistant layer 312, the corrosion-resistant layer 313, the waterproof coating 314, the waterproof membrane 315 and the bottom plate 316 are combined in sequence from top to bottom to form a waterproof board 31.

[0022] In addition, the anti-skid layer 311 is a PVC film, which is also called a polyvinyl chloride film. It has good anti-skid and wear resistance. Due to its special surface treatment and the added anti-skid agent, it can maintain stable friction in dry, wet or sweaty conditions, effectively reducing the risk of slipping, and can enhance the anti-skid property of the base plate 316, reducing the phenomenon of passers-by slipping due to the slippery waterproof board 31. The wear-resistant layer 312 is a wear-resistant rubber film, which is made of silicone rubber. Silicone rubber is a polymer material with the characteristics of wear resistance, high elasticity, aging resistance, radiation resistance, and high and low temperature resistance, thereby enhancing the wear resistance of the base plate 316. The corrosion-resistant layer 313 is a polyurethane anti-corrosion paint. The polyurethane anti-corrosion paint is a paint base composed of hydroxyl resin, various pigments, additives and organic solvents, and is developed into an anti-corrosion paint with aliphatic polyisocyanate as a curing agent, so that the waterproof board 31 can reduce the corrosion caused by the external environment when in use.

[0023] Meanwhile, the waterproof coating 314 is an acrylic waterproof coating, which is a single-component water-emulsion waterproof coating made by adding other additives to pure acrylic polymer emulsion as the base material. The waterproof film formed by the waterproof coating after curing has certain elongation, elasticity, crack resistance, impermeability and weather resistance, and can play a role in waterproofing, anti-seepage and protection. The waterproof film 315 is a polyethylene waterproof film, also known as a PE film waterproof roll, which has good waterproofness, high mechanical strength, aging resistance, strong puncture resistance, large friction coefficient, flexibility, corrosion resistance and other characteristics.

[0024] See also Figure 2In this embodiment, the connection assembly includes a plurality of connection blocks 32 fixed at the left and right ends of the lower end of the bottom plate 316, and the connection assembly also includes a plurality of connection grooves 33 arranged on the top of the floor body 1 and the prefabricated staircase body 2.

[0025] Secondly, the connecting block 32 is located inside the connecting groove 33, and the connecting block 32 and the connecting groove 33 are plugged in. The waterproof board 31 can be inserted into the multiple connecting grooves 33 on the floor main body 1 and the prefabricated stair main body 2 through the connecting blocks 32 at the left and right ends, so that the waterproof board 31 can be firmly installed on the floor main body 1 and the prefabricated stair main body 2, so that the waterproof board 31 can cover the splicing seam between the floor main body 1 and the prefabricated stair main body 2, and can ensure the waterproofness of the splicing seam between the floor main body 1 and the prefabricated stair main body 2.

[0026] The working principle of the above embodiment is:

[0027] When in use, the bottom plate 316 can be plugged and installed in the connecting groove 33 between the floor main body 1 and the prefabricated stair main body 2 through two groups of connecting blocks 32. The waterproof property of the bottom plate 316 can be enhanced by the waterproof coating 314 and the waterproof membrane 315, so that the bottom plate 316 can become a waterproof plate 31, so that the waterproof plate 31 can cover the splicing seam between the floor main body 1 and the prefabricated stair main body 2, so as to waterproof the splicing seam between the floor main body 1 and the prefabricated stair main body 2, avoid affecting the quality of the splicing end of the prefabricated stair main body 2 and the floor main body 1, thereby reducing the service life of the prefabricated stair main body 2, and the waterproof plate 31 can reduce the phenomenon of passers-by slipping due to the slippery waterproof plate 31 through the anti-slip layer 311, and the wear resistance of the waterproof plate 31 can be enhanced through the wear-resistant layer 312, which can enhance the wear resistance of the waterproof plate 31, and the waterproof plate 31 can reduce the phenomenon of corrosion of the waterproof plate 31 caused by the external environment through the corrosion-resistant layer 313, thereby enhancing the service life of the waterproof plate 31.
