Abstract
Description
Technical Field
[0001] This utility model relates to the field of exterior wall construction technology, and in particular to an exterior wall expansion joint cover plate structure. Background Technology
[0002] An exterior wall expansion joint is a type of structural joint used primarily to prevent cracks or damage to the exterior walls of buildings caused by factors such as temperature changes, uneven foundation settlement, and earthquakes. It ensures sufficient space for deformation by leaving gaps in deformation-sensitive areas of the exterior wall, thereby protecting the building's integrity and stability.
[0003] Exterior wall expansion joints are widely used in various modern buildings, especially super high-rise and large-scale building projects. They can cope with the deformation caused by thermal expansion and contraction, settlement and earthquakes, protecting the integrity and aesthetics of the building;
[0004] Expansion joints in exterior walls are subject to environmental influences and may exhibit some movement. However, most expansion joints are concealed using sealant. But after a period of use, the sealant dries and hardens, and the expansion joint is prone to peeling off entirely due to thermal expansion and contraction, thus reducing its service life. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned problems and shortcomings by proposing an exterior wall expansion joint cover plate structure. Hidden plate one and hidden plate two are respectively attached to the expansion groove and the adhesive groove. After the adhesive dries, hidden plate one and hidden plate two are respectively fixed to the exterior decorative panel, which facilitates the concealment of the expansion joint, allows for thermal expansion and contraction, and improves service life.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An exterior wall expansion joint cover structure includes a wall and an expansion joint on the outer wall of the wall. The outer wall of the wall has equally spaced fixing grooves and an exterior decorative panel. The exterior decorative panel has an installation component at the fixing groove and an expansion component at the expansion joint. The installation component includes an insertion protrusion on the outer wall of the exterior decorative panel at the fixing groove, an installation groove on the outer wall of the exterior decorative panel at the insertion protrusion, and an installation hole on the outer wall of the exterior decorative panel at one end of the installation groove and in the wall at the fixing groove. The expansion component includes an expansion groove on the outer wall of the exterior decorative panel near the expansion joint, an adhesive groove on the outer wall of the expansion groove, and a first hidden plate and a second hidden plate respectively located at the expansion groove.
[0008] Preferably, the protrusion on the exterior panel is slidably connected to the outer wall of the fixing groove in the wall, and expansion screws are provided in the mounting holes in the wall and the exterior panel.
[0009] Preferably, the outer wall of the outer trim panel located at one end of the mounting groove has an annular groove, and a cap is inserted into the outer wall of the outer trim panel at the mounting groove.
[0010] Preferably, both the first hidden plate and the second hidden plate are welded with adhesive strips at the adhesive groove, and the outer walls of the adhesive strips and the outer walls of the first hidden plate and the second hidden plate are coated with adhesive.
[0011] Preferably, a sliding groove is provided on the outer wall of one end of the hidden plate one, and a sliding strip is provided on the outer wall of one end of the hidden plate two, the sliding strip being slidably connected in the sliding groove.
[0012] Preferably, the outer trim panel has an "L" shaped cross-section, and the outer wall of the outer trim panel located at the adhesive groove is located in the expansion joint.
[0013] Preferably, the adhesive strip is inserted into the inner wall of the adhesive groove, and the outer walls of the first and second hidden plates are attached to the outer wall of the expansion groove.
[0014] The beneficial effects of this utility model are as follows:
[0015] 1. Attach Hidden Plate 1 and Hidden Plate 2 to the expansion groove and adhesive groove respectively. After the adhesive dries, Hidden Plate 1 and Hidden Plate 2 are fixed to the outer trim panel respectively. This facilitates the concealment of the expansion joint, allows for thermal expansion and contraction, improves service life, and reduces the chance of falling off.
[0016] 2. An installation hole is made in the wall by inserting the installation groove into the center of the protrusion. Then, one end of the expansion screw is inserted into the installation hole. After the expansion screw is tightened, the outer panel is firmly fixed to the outer wall, improving the installation stability and firmness. Attached Figure Description

The mounting hole 8 is opened on the wall 1 through the center of the mounting groove 7 in the extension protrusion. Then, one end of the expansion screw 9 is inserted into the mounting hole 8. After the expansion screw 9 is tightened, the exterior panel 4 is firmly fixed to the outer wall of the wall 1, improving the installation stability and firmness.
[0026] The protrusion on the exterior panel 4 is slidably connected to the outer wall of the fixing groove 2 of the wall 1, and expansion screws 9 are provided in the mounting holes 8 on the wall 1 and the exterior panel 4.
[0027] The outer wall of the exterior trim panel 4 located at one end of the mounting groove 7 has an annular groove 10, and a cap 11 is inserted into the outer wall of the exterior trim panel 4 at the mounting groove 7. One end of the cap 11 is inserted into the annular groove 10 of the mounting groove 7. The cap 11 seals and hides the mounting groove 7 to prevent rainwater from entering and corroding the expansion screw 9.
