Description

Technical Field

[0001] This utility model belongs to the field of building expansion joint technology, and in particular relates to a double-layer sealed expansion joint for building structures. Background Technology

[0002] Double-layer sealing expansion joints are expansion joint structures that improve waterproofing, dustproofing, and shock absorption performance through a double-sealing layer design. The core principle is to use two layers of sealing materials of different materials or structures to work together to compensate for the defects of a single seal and enhance overall reliability. The main types include material combination double seals and structural double seals. Structural double seals are designed with two layers of metal plates (such as stainless steel plates, aluminum alloy plates) or composite material plates to form a "sandwich" structure, with an elastic sealing layer (such as rubber gaskets or sealant) in the middle. The outer metal plate resists external loads and environmental corrosion, while the inner metal plate fixes the sealing material and assists in the installation of the outer metal plate. The two layers work together to improve sealing reliability and structural strength.

[0003] Currently, most buildings use double-layer sealed expansion joints for construction. These joints typically use an inner metal plate to fix the sealing material. After a period of use, the sealing material will age and need to be replaced. However, the installation and positioning of the inner metal plate in a double-layer sealed expansion joint is quite troublesome. Therefore, there is a need for a double-layer sealed expansion joint that can fix the sealing material through a fixed structure, avoiding the need for users to disassemble and reassemble the inner metal plate when replacing the sealing material, thus improving the speed of sealing material replacement. Utility Model Content

[0004] The purpose of this utility model is to provide a double-layer sealed expansion joint for building structures, which can fix the sealing material through a fixing structure, avoiding the need for users to disassemble and reassemble the inner metal plate when replacing the sealing material, thus improving the speed of sealing material replacement and solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A double-layer sealed expansion joint for building structures includes a sliding plate disposed between two concrete slabs. Each of the two concrete slabs has an installation base plate on one opposite side. Each of the two installation base plates has a locking member fixedly connected to one opposite side. Locking blocks are fixedly connected to both sides of the sliding plate. The locking members and locking blocks are compatible. A positioning plate is fixedly connected to the side of the installation base plate away from the concrete slab. A sealing sheet is disposed on the side of the installation base plate close to the concrete slab. A row of identical fixing screws is provided through the side of the installation base plate away from the concrete slab. A plate and a sealing sheet are threadedly connected to a concrete slab. A sealing strip is provided between the two concrete slabs. Two symmetrical positioning plates are provided between the two concrete slabs. The positioning plates are in contact with the sealing strip. A row of identical fixing screws is provided through the side of the positioning plate away from the sealing strip. The fixing screws pass through the positioning plates and the sealing strip and are threadedly connected to the concrete slab. A protective cover is provided on the top of the two concrete slabs. A row of longitudinal fixing screws is provided through the top of the protective cover. The fixing screws pass through the protective cover and are threadedly connected to the sliding plate. The top of the protective cover has multiple identical drainage channels.

[0006] Preferably, a sealing gasket is provided on the top of each of the two concrete slabs, and the top of the sealing gasket is in contact with the bottom of the protective cover.

[0007] Preferably, the card block is cylindrical, the second positioning plate is L-shaped, and the bottom of the second positioning plate is in contact with the sealing strip.

[0008] Preferably, both sides of the protective cover are inclined surfaces, and a row of identical mounting holes are opened at the bottom of the protective cover, with the second fixing screw located in the inner cavity of the mounting hole.

[0009] Preferably, a sealing ring is fitted on the surface of the second fixing screw, the sealing ring is located in the inner cavity of the mounting hole, and the corners of the sealing gasket are rounded.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a fixing screw to fix the mounting base plate to one side of two concrete slabs, and then places the sealing strip between the two symmetrical concrete slabs, so that the positioning plate two is attached to the surface of the sealing strip. The top of the positioning plate two pushes one side of the sealing strip into the inner cavity of the sealing gasket. The positioning plate two is fixed by the fixing screw, so that the sealing material can be fixed by the fixing structure. This avoids the need for the user to disassemble and reassemble the inner metal plate when replacing the sealing material, thus improving the speed of sealing material replacement.

[0012] 2. By setting a sealing gasket, when the protective cover is fixed on the top of the concrete slab, the sealing gasket will seal the gap between the concrete slab and the protective cover, preventing rainwater from seeping into the space between the two concrete slabs and providing the protective cover with a tight seal.

[0023] Working principle: When using this utility model, the user places the mounting base 3 between two symmetrical concrete slabs 1, and then places the sealing plate 7 on the side of the mounting base 3 closest to the concrete slab 1. The fixing screw 8 passes through the mounting base 3 and the sealing plate 7 and is threadedly connected to the concrete slab 1, thus fixing the mounting base 3 to the concrete slab 1. Then, the sealing strip 9 is placed between the two concrete slabs 1, so that the positioning plate 10 fits against the sealing strip 9. The top of the positioning plate 10 pushes the sealing strip 9 into the bottom of the positioning plate 6, thereby allowing the fixing screw 8 to pass through the positioning plate 10 and the sealing strip 9 and be threadedly connected to the concrete slab 1. This completes the installation of the sealing strip 9, avoiding the need for the user to disassemble and reassemble the inner metal plate when replacing the sealing material, and improving the speed of sealing material replacement.

[0024] In summary, this building structure features a double-layer sealed expansion joint. The mounting base 3 is fixed to one side of two opposing concrete slabs 1 using a fixing screw 8. A sealing strip 9 is then placed between the two symmetrical concrete slabs 1, allowing a positioning plate 10 to adhere to the surface of the sealing strip 9. The top of the positioning plate 10 pushes one side of the sealing strip 9 into the inner cavity of the sealing gasket 14. The positioning plate 10 is then fixed using the fixing screw 8. This structure effectively secures the sealing material, eliminating the need for users to disassemble and reassemble the inner metal plate when replacing the sealing material, thus improving the speed of sealing material replacement.
