Description

Technical Field

[0001] This application relates to the field of building engineering technology, and in particular to a floor separation joint structure. Background Technology

[0002] Floor expansion joints are artificial gaps specially designed during the construction of flooring (such as concrete flooring, epoxy flooring, asphalt flooring, etc.) to cope with the material's own characteristics and the influence of the external environment. Their core function is to release stress, control cracks, and ensure the stability and durability of the flooring structure.

[0003] Existing floor expansion joints are mostly made of extruded polystyrene (XPS) boards. XPS boards are lightweight, high-strength, easy to cut and transport, and can be laid quickly after the ground is leveled, thus shortening the construction cycle.

[0004] The existing technical solutions mentioned above have the following defects: when using extruded polystyrene boards to separate the floor expansion joints, water and corrosive media may seep into the floor base layer through the damaged expansion joints, causing the floor to sand, become hollow, and the steel bars to rust. Utility Model Content

[0005] In order to reduce the seepage of liquids into the subfloor and ensure the structural stability of the floor, this application provides a floor expansion joint structure.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: A floor expansion joint structure includes a surface layer and a subbase layer. An expansion joint is provided on the surface layer, and an extruded polystyrene board is embedded in the expansion joint. A waterproof strip is fixed to the extruded polystyrene board, and a placement groove is provided on the extruded polystyrene board. An absorbent strip is embedded in the placement groove.

[0007] By adopting the above technical solutions, the extruded polystyrene board has high compressive strength to support the waterproof strip, and the extruded polystyrene board has a certain degree of elasticity, which can buffer the stress caused by the thermal expansion and contraction of the floor. The waterproof strip can form an elastic sealing layer, which can reduce the liquid seepage into the gap between the extruded polystyrene board and the surface layer. The extruded polystyrene board supports the elastic waterproof strip, and the absorbent strip can absorb liquid, reducing the liquid seeping into the floor base layer and ensuring the structural stability of the floor.

[0008] Optionally, the absorbent strip is made of a water-absorbing and swelling material.

[0009] By adopting the above technical solution, the absorbent strip can absorb liquid and expand, which can reduce the gap between the extruded board and the surface layer, prevent liquid from flowing into the subfloor along the extruded board, reduce the liquid seeping into the subfloor base layer, and ensure the structural stability of the floor.

[0010] Optionally, a tensile tube is provided inside the surface layer, and the tensile tube is inserted into the extruded board.

[0011] By adopting the above technical solutions, tensile tubes can improve the tensile strength of the surface layer, reduce the risk of uneven stress damage to the surface layer caused by thermal expansion and contraction of the floor, reduce the extension of cracks in the surface layer, and ensure the structural stability of the floor.

[0012] Optionally, a waterproof membrane is provided at the bottom of the surface layer, and the waterproof membrane is located below the expansion joint and covers the expansion joint.

[0013] By adopting the above technical solutions, the waterproof membrane can reduce the flow of liquid into the subfloor layer, thus ensuring the structural stability of the floor.

[0014] Optionally, the extruded board has a water-retaining groove for the waterproof strip to be embedded in.

[0015] By adopting the above technical solutions, the water-retaining groove can increase the contact area between the waterproof strip and the extruded polystyrene board, improve the stability of the connection between the waterproof strip and the extruded polystyrene board, and ensure the structural stability of the floor.

[0016] Optionally, a water baffle is fixedly attached to the extruded board.

[0017] By adopting the above technical solution, the water barrier can deform with the thermal expansion and contraction of the expansion joint, ensuring the stability of the connection between the side wall of the waterproof strip and the surface layer.

[0018] Optionally, a sponge rod is inserted inside the tensile tube.

[0019] By adopting the above technical solution, the sponge rod can absorb the liquid in the tensile tube, reduce the liquid seeping into the subfloor base layer from the surface layer, and ensure the structural stability of the floor.

[0020] Optionally, a wire mesh is provided inside the padding layer.

[0021] By adopting the above technical solutions, steel wire mesh can improve the overall structural strength of the subfloor, reduce the dangers of liquid seepage causing sanding and hollowing of the subfloor, and ensure the structural stability of the floor.

[0022] In summary, this application has the following technical effects: By incorporating extruded polystyrene (XPS) boards, waterproof strips, and absorbent strips, the XPS boards, with their elasticity, can buffer the stress caused by the thermal expansion and contraction of the floor. The waterproof strips form an elastic sealing layer, reducing liquid penetration into the gaps between the XPS boards and the surface layer. The XPS boards support the elastic waterproof strips, and the absorbent strips absorb liquid, reducing the amount of liquid penetrating into the floor base layer and ensuring the structural stability of the floor. By installing tensile tubes, the tensile strength of the surface layer can be improved, reducing the risk of uneven stress damage caused by thermal expansion and contraction of the floor, reducing the extension of cracks in the surface layer, and ensuring the structural stability of the floor. By installing a waterproof membrane, the amount of liquid flowing into the subfloor can be reduced, thus ensuring the structural stability of the floor. Attached Figure Description

[0025] The present application will be further described in detail below with reference to the accompanying drawings. Example

[0026] Embodiment 1 of this application discloses a floor expansion joint structure, referring to... Figure 1 The floor expansion joint structure includes a surface layer 1 and a subbase layer 2. The surface layer 1 is located above the subbase layer 2. An expansion joint 11 is provided on the surface layer 1. An extruded polystyrene board 3 is embedded in the expansion joint 11. The extruded polystyrene board 3 is a strip-shaped board. The extruded polystyrene board 3 is located in the expansion joint 11 and both sides of the board are attached to the surface layer 1. A waterproof strip 4 is provided on the side of the extruded polystyrene board 3 away from the subbase layer 2. In this embodiment, the waterproof strip 4 is a waterproof strip 4 made of waterproof sealant. One side of the waterproof strip 4 is flush with the top surface of the surface layer 1.

[0027] Reference Figure 1 and Figure 2 A waterproof membrane 5 is provided at the bottom of the surface layer 1. The waterproof membrane 5 is located between the surface layer 1 and the padding layer 2. In this embodiment, the waterproof membrane 5 is made of waterproof roll material. The waterproof membrane 5 is located below the expansion joint 11 and can cover the expansion joint 11. Tensile tubes 6 are provided inside the surface layer 1. Multiple tensile tubes 6 are provided at intervals. In this embodiment, the tensile tubes 6 are made of polyethylene material. The tensile tubes 6 pass through the extruded polystyrene board 3 and the expansion joint 11.

[0028] When using the floor expansion joint structure, the high compressive strength of the extruded polystyrene board 3 can support the waterproof strip 4, and the extruded polystyrene board 3 has a certain degree of elasticity, which can buffer the stress caused by the thermal expansion and contraction of the floor. The waterproof strip 4 can form an elastic sealing layer, which can reduce the liquid seepage into the gap between the extruded polystyrene board 3 and the surface layer 1. By supporting the elastic waterproof strip 4 through the extruded polystyrene board 3, the liquid seeping into the floor base layer is reduced, ensuring the structural stability of the floor.

[0029] The waterproof membrane 5 reduces the inflow of liquid into the subfloor layer 2, ensuring the structural stability of the floor. The tensile tube 6, which passes through the extruded polystyrene board 3 and the expansion joint 11, improves the tensile strength of the surface layer 1, reduces the risk of uneven stress damage to the surface layer 1 caused by thermal expansion and contraction of the floor, reduces the extension of cracks within the surface layer 1, and ensures the structural stability of the floor. Example

[0030] The difference between Embodiment 2 and Embodiment 1 of this application is that, referring to... Figure 1 and Figure 2 A water-blocking groove 31 is provided on the side of the extruded polystyrene board 3 away from the padding layer 2. The water-blocking groove 31 is arranged along the length direction of the extruded polystyrene board 3. The waterproof strip 4 is embedded in the water-blocking groove 31. Water-blocking plates 32 are glued to both sides of the groove near the surface layer 1. In this embodiment, the water-blocking plate 32 is made of elastic material. The water-blocking plate 32 is arranged along the length direction of the water-blocking groove 31. The side of the water-blocking plate 32 away from the water-blocking groove 31 abuts against the surface layer 1.

[0031] The water-retaining groove 31 increases the contact area between the waterproof strip 4 and the extruded polystyrene board 3, improves the stability of the connection between the waterproof strip 4 and the extruded polystyrene board 3, and ensures the structural stability of the floor. The water-retaining plate 32 can deform with the thermal expansion and contraction of the expansion joint 11, ensuring the stability of the connection between the side wall of the waterproof strip 4 and the surface layer 1.

[0032] Reference Figure 1 and Figure 2 On both sides of the extruded polystyrene board 3 near the waterproof strip 4, there are placement grooves 33. The placement grooves 33 are set along the length of the extruded polystyrene board 3. A water-absorbing strip 7 is embedded in the placement groove 33. In this embodiment, the water-absorbing strip 7 is made of water-absorbing and expanding material. One side of the water-absorbing strip 7 extends out of the groove of the placement groove 33 and abuts against the surface layer 1. A sponge rod 61 is inserted into the tensile tube 6. The sponge rod 61 is set along the length of the tensile tube 6. A wire mesh 21 is set in the padding layer 2.

[0033] When liquid flows into expansion joint 11 along extruded polystyrene board 3, the absorbent strip 7 in the groove 33 can absorb the liquid and expand, which can reduce the gap between extruded polystyrene board 3 and surface layer 1, prevent liquid from flowing into subbase 2 along extruded polystyrene board 3, reduce the liquid seeping into the subbase of the floor, and ensure the structural stability of the floor.

[0034] The sponge rod 61 can absorb the liquid in the tensile tube 6, reduce the liquid seeping into the subfloor base layer from the surface layer 1, and ensure the structural stability of the floor.

[0035] The wire mesh 21 inside the subbase 2 can improve the overall structural strength of the subbase 2, reduce the danger of liquid seepage causing the subbase 2 to become sandy or hollow, and ensure the structural stability of the floor.

[0036] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
