Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, and specifically relates to a cantilevered expansion joint cover. Background Technology

[0002] Expansion joints, also known as building expansion joints, are structural joints artificially created at specific locations along the construction joint direction of a building or structure to prevent cracks or damage caused by changes in climate temperature (thermal expansion and contraction). Expansion joints divide building components above the foundation, such as walls, floors, and roofs (except for wooden roofs), into two independent parts, allowing the building or structure to expand and contract horizontally perpendicular to the joint direction.

[0003] According to patent CN213390615U, an expansion joint cover plate is disclosed, including an insert plate and a cover plate. The insert plate is inserted into both ends of the bottom surface of the cover plate along the axial direction. The top surface of the cover plate has several through holes at equal intervals along the axial direction. The bottom surface of the cover plate has several buffer mechanisms installed at equal intervals along the axial direction. The beneficial effects of this invention are that the insert plate of the expansion joint cover plate is used to install the entire cover plate, and the rubber material can also compensate for the expansion and contraction movement of the expansion joint perpendicular to the axial direction, avoiding impact damage caused by the rigid connection between the cover plate and the expansion joint surface. Secondly, the expansion joint of this invention has compression springs arranged on the bottom surface to compensate for external force impact perpendicular to the bottom surface of the expansion joint. Finally, the through holes on the cover plate improve the drainage performance of the cover plate and prevent water accumulation in buildings or structures from being unable to drain.

[0004] Existing expansion joint cover methods all have certain drawbacks. When the cover is exposed, the facade design is inconsistent. The insulation and decorative layer is separated by the cover at the expansion joint, which greatly reduces the appearance. On the other hand, if the expansion joint cover is concealed, the vertical joint is very prone to cracking during the temperature stress shrinkage deformation of the main structure or earthquakes, and the repair is difficult. Summary of the Invention

[0005] The purpose of this invention is to provide a cantilevered expansion joint cover for existing devices, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cantilever expansion joint cover plate, including a web plate, wherein the back of the web plate is provided with an I-shaped connector for connecting to the wall, and the I-shaped connector is connected to the finished expansion joint cover plate by self-tapping screws, and the surface of the web plate is provided with a fiber cement pressure plate.

[0007] The present invention further illustrates that the I-shaped connector is made of aluminum alloy and the thickness of the I-shaped connector is 2mm.

[0008] The present invention further describes that the web is made of aluminum alloy plate by stamping and grinding, the height of the web is 60cm, the thickness of the web is 3mm, and the width of the web is 25cm.

[0009] The present invention further illustrates that the fiber cement pressure board has a thickness of 10cm, a length of 60cm, and a width of 20cm.

[0010] The present invention further illustrates that the fiber cement pressure board is connected by strong adhesive and self-tapping screws respectively.

[0011] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention,

[0012] By setting I-shaped connectors and fiber cement pressure boards on both sides of the web, a local improvement was made, and a cantilevered integrated insulation panel expansion joint cover was invented. While ensuring the uniform appearance of the exterior integrated insulation panel decoration, the expansion joint position of the insulation board is increased with the deformation of the main structure, and the probability of vertical glue cracking after caulking is reduced.

[0018] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention.

[0019] Please see Figure 1-3The present invention provides a technical solution: a cantilever expansion joint cover plate, including a web plate 2, an I-shaped connector 1 for connecting to the wall on the back of the web plate 2, and the I-shaped connector 1 is connected to the finished expansion joint cover plate by self-tapping screws, and a fiber cement pressure plate 3 is provided on the surface of the web plate 2.

[0020] By setting I-shaped connectors 1 and fiber cement pressure boards 3 on both sides of the web 2, a local improvement was made, and a cantilevered integrated insulation board expansion joint cover was invented. While ensuring the uniform appearance of the exterior integrated insulation board decoration surface, the expansion joint position of the insulation board is increased with the deformation of the main structure, and the probability of vertical glue cracking after applying glue is reduced.

[0021] The I-beam connector 1 is made of aluminum alloy and has a thickness of 2mm. The web plate 2 is made of aluminum alloy sheet by stamping and grinding. The height of the web plate 2 is 60cm, the thickness of the web plate 2 is 3mm, and the width of the web plate 2 is 25cm. The fiber cement pressure plate 3 has a thickness of 10cm, a length of 60cm, and a width of 20cm. The fiber cement pressure plate 3 is connected to the other components by strong adhesive and self-tapping screws.

[0022] Based on the design drawings, after calculating the thickness of the insulation board and adhesive mortar, design and fabricate I-beam connector 1 to ensure that the integrated insulation board panels are on the same plane. Install the prefabricated structural expansion joint cover plate on the structural surface. The expansion joint cover plate is fixed to the exterior wall of the main structure according to the design requirements. Adhere the decorative integrated insulation board and cantilever cover plate. Fix the I-beam connector 1 to the prefabricated expansion joint cover plate using self-tapping screws. Leave a 1-2cm gap between the insulation board base layer and the aluminum alloy web plate 2 as a space for shrinkage deformation. Install the expansion joint cover plate surface layer and apply adhesive. Use adhesive mortar on the cement board to adhere the integrated insulation board panel, which is generally 5mm thick, to the cement pressure board. The mortar thickness is adjusted according to the plane of the integrated insulation board surface layers on both sides to ensure that they are on the same plane. The adhesive joint width is 25mm.
