Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a waterproof structure of a staircase sliding support. Background Art

[0002] Stair sliding bearings play an important role in construction projects. They can form a movable joint between the floor and the stair sections, so that when the floor moves, the stair sections can slide along the surface of the floor to avoid damage between the floor and the stair sections.

[0003] Figure 1 The schematic diagram of the installation of the stair sliding support 3 between the floor 1 and the stair section 2 in the prior art is shown. The sliding support 3 is a long plate-shaped structure, which is arranged between the bottom surface of the lower end of the stair section 2 and the upper surface of the end of the floor 1. The existing stair sliding support 3 is often designed without considering the waterproofing problem, which results in that during use, water will penetrate between the floor 1 and the stair section 2 along the gap between the sliding support 3 and the floor 1 and the gap between the sliding support 3 and the bottom surface of the lower end of the stair section 2, causing water seepage and leakage, which seriously affects the service life and safety of the building.

[0004] At present, some existing waterproof technologies include using waterproof gaskets around the stair sliding support 3, etc. These methods may have a certain effect on preventing leakage, but they cannot completely solve the problem because when the stair sliding support 3 is displaced, the waterproof gasket may break or fall off, causing the waterproof layer to lose its function.

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described below with reference to the accompanying drawings.

[0024] The utility model discloses a waterproof structure for a staircase sliding support, such as Figure 2 As shown, the stair sliding support 3 is installed between the bottom surface of the lower end of the stair section 2 and the upper surface of one end of the floor 1, and the stair sliding support 3 is arranged at the intersection of the stair section 2 and the floor 1, wherein the floor 1 refers to the rest platform floor connected between the upper and lower stair sections 2.

[0025] A waterproof layer is provided on the vertical skirting surface 21 connected to the floor 1 at the lower end of the stair section 2 and on the floor 1. The material of the waterproof layer is an aluminum alloy cover plate 5 and a synthetic polymer waterproof membrane 4.

[0026] A synthetic polymer waterproof membrane 4 is arranged on the surface of the vertical skirting surface 21 connected to the floor 1 at the lower end of the stair section 2, and a synthetic polymer waterproof membrane 4 is arranged on the upper surface of the floor 1 close to the stair sliding support 3; an aluminum alloy cover plate 5 is arranged on the vertical skirting surface 21 connected to the floor 1 at the lower end of the stair section 2 and on the upper surface of the floor 1 close to the stair sliding support 3, and the aluminum alloy cover plate 5 is arranged on the synthetic polymer waterproof membrane 4, and the aluminum alloy cover plate 5 covers the polymer waterproof membrane 4; a sealing material 6 is arranged at the junction of the aluminum alloy cover plate 5 on the floor 1 and the aluminum alloy cover plate 5 on the skirting surface 21, and a caulking glue 7 is arranged at the junction of the surface layer of the floor 1, the sealing material 6 and the surface layer of the skirting surface 21.

[0027] The sliding support plate 2 is a polytetrafluoroethylene plate with an elongated plate-shaped structure, and the sliding support plate 2 is as wide as the bottom surface of the lower end of the ladder section 2 .

[0028] The polytetrafluoroethylene plate has good sliding properties. When there is an earthquake or other external forces, the stair section 2 can slide left and right along the surface of the floor 1, thereby eliminating the adverse effects of the diagonal brace of the stair section 2 on the frame column, so that the stair itself does not participate in the vibration of the entire structure; the polytetrafluoroethylene is resistant to acids and alkalis, and various organic solvents, and is almost insoluble in all solvents. Polytetrafluoroethylene is resistant to high temperatures and has an extremely low friction coefficient, so it can be used as a lubricant and also becomes an ideal coating for the inner layer of easy-to-clean water pipes. Polytetrafluoroethylene stair treads are mainly used in engineering stairs. They are a kind of hard polytetrafluoroethylene stair bearings, which are quite widely used in current stairs. Because the stairwell does not participate in the overall seismic calculation of the structure, sliding bearings need to be designed according to the traffic restrictions. The types and specifications of the polytetrafluoroethylene plates used in the stairs must meet the design requirements and construction specifications. The surface of the PTFE sheet is required to be flat and clean. Usage: The thickness of the PTFE sheet for stairs is 5mm, its length is equal to the length of the bottom surface of the lower end of the stair section 2, and its width is equal to the width of the bottom surface of the lower end of the stair section 2; the PTFE sheet for stairs needs to be cut using a profile cutting machine.

[0029] The synthetic polymer waterproofing roll 4 is made of synthetic rubber, synthetic resin or a blend of the two as the base material, with appropriate amounts of chemical additives and fillers added. It is processed through different processes to form a rollable sheet waterproof material; or the above materials are compounded with synthetic fibers to form two or more layers of rollable sheet waterproof materials. It can be made of terpolymer rubber waterproofing roll, chloroprene rubber roll, chloroprene rubber ethylene waterproofing roll, chlorinated polyethylene waterproofing roll or chlorinated polyethylene rubber blended roll. The synthetic polymer waterproofing roll 4 is pasted on the vertical skirting surface 21 connected to the floor 1 at the lower end of the stair section 2, and on the upper surface of the floor 1 close to the stair sliding support 3; the thickness of the synthetic polymer waterproofing roll 4 is 1.2 mm.

[0030] The aluminum alloy cover plate 5 is a 1mm thick aluminum alloy plate, which is waterproof at the deformation joint. Aluminum alloy cover plate is a common industrial product with the advantages of corrosion resistance, light weight, high strength, and easy processing. Aluminum alloy cover plates are usually made of high-quality aluminum alloy materials such as 6061-T6 and 6063-T5, which have good corrosion resistance and oxidation resistance and can be used in various environmental conditions; aluminum alloy has good corrosion resistance and can be used in corrosive environments such as acid, alkali, and salt to protect facilities from damage; aluminum alloy cover plates can be recycled and reused, meeting environmental protection requirements; the aluminum alloy cover plate 5 is fixed to the vertical skirting surface 21 or the upper surface of the floor 1 by expansion bolts 8.

[0031] The aluminum alloy cover plate 5 on the upper surface of the floor 1 extends toward one end of the stair section 2 toward the bottom end of the stair section 2, and the lower end of the aluminum alloy cover plate 5 on the vertical skirting surface 21 extends toward the direction of the floor 1. When there is an earthquake or other external force, in order to facilitate the stair section 2 to slide left and right along the surface of the floor 1, the aluminum alloy cover plate 5 on the upper surface of the floor 1 and the aluminum alloy cover plate 5 on the straight skirting surface 21 are not designed to be integrated. There is a gap at the intersection of the aluminum alloy cover plate 5 on the upper surface of the floor 1 and the aluminum alloy cover plate 5 on the skirting surface 21. The intersection of the aluminum alloy cover plate 5 on the upper surface of the floor 1 and the aluminum alloy cover plate 5 on the straight skirting surface 21 is the intersection of the bottom end of the stair section 2 and the upper surface of the floor 1, and the gap where the aluminum alloy cover plate 5 on the upper surface of the floor 1 and the aluminum alloy cover plate 5 on the skirting surface 21 meet is coated with sealing material 6.

[0032] The sealing material 6 can be selected from modified asphalt paste, polyurethane building sealant, acrylic building sealant, etc.

[0033] Except for the portion where the sealing material 6 is applied to the junction between the aluminum alloy cover plate 5 on the upper surface of the floor slab 1 and the upper surface of the floor slab 1, the other junction portions between the aluminum alloy cover plate 5 on the upper surface of the floor slab 1 and the upper surface of the floor slab 1 are all coated with building sealant 9.

[0034] Except for the portion where the sealing material 6 is applied to the junction between the aluminum alloy cover plate 5 of the skirting surface 21 and the skirting surface 21 , the other junction portions between the aluminum alloy cover plate 5 on the skirting surface 21 and the skirting surface 21 are all coated with a building sealant 9 .

[0035] The construction sealant 9 can be polyurethane construction sealant, acrylic construction sealant, etc.

[0036] When the synthetic polymer waterproof membrane 4 and the aluminum alloy cover plate 5 are laid or installed on the floor 1 and the skirting surface 21, and the sealing material 6 and the building sealant 9 are applied, a surface layer 10 can be set on the floor 1 and the skirting surface 21. The surface layer 10 is designed separately according to the design situation, and the surface layer 10 can be ceramic tiles or cement, etc.

[0037] There is a gap at the intersection of the surface layer of the floor slab 1, the sealing material 6 and the surface layer of the skirting surface 21, and a caulking glue 7 is applied to the gap at the intersection of the surface layer of the floor slab 1, the sealing material 6 and the surface layer of the skirting surface 21.

[0038] The caulking glue 7 is made of modified petroleum asphalt sealing material or synthetic polymer sealing material. The joint sealing and waterproofing design should ensure that the sealing part is watertight, and the joint sealing and waterproofing should match the main body waterproof layer. The embedding depth of the caulking glue 7 is preferably 50% to 70% of the joint width.

[0039] Finally, it should be noted that the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field. The above description is only the preferred embodiment of the utility model and is not used to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
