Description

Technical Field

[0001] The invention relates to the technical field of building facilities, and in particular to a deformation joint covering device. Background Art

[0002] Deformation joints are a general term for expansion joints, settlement joints and seismic joints. Buildings often deform under the influence of external factors, resulting in cracks or even damage. Deformation joints are structural joints reserved for this situation. Under normal circumstances, deformation joints need to be covered with deformation joint covering devices during construction. Existing deformation joint covering devices generally include a base and a cover plate set on the edges of both sides of the deformation joint. The cover plate is generally V-shaped and W-shaped. The cover plate can slide up and down between the two sides and the base. When the building is settling, the base and the cover plate fixed to the building can slide relative to each other, and will not damage the deformation joint covering device itself and the building. When the width of the deformation joint changes due to temperature changes and other factors between the buildings, the V-shaped or W-shaped cover plate can be elastically deformed in the horizontal direction to adapt to the change in the width of the joint. However, when the cover plate is deformed in the horizontal direction, the fixing devices such as nails used to fix the base will be subjected to greater stress. When the width of the joint changes greatly, the nails may fall off. In severe cases, the deformation joint covering device may slip, the tiles on the surface of the building may fall off, and water may leak, which poses a great safety hazard.

[0003] Therefore, how to solve the problem in the prior art that V-shaped or W-shaped cover plates are used to adapt to the change in seam width at temperature, which causes the fixing devices such as nails to be subjected to greater stress, has become a technical problem that technical personnel in this field urgently need to solve.

[0029] Optionally, the above-mentioned base 3 may include a bottom plate 301, the above-mentioned sliding connection structure is arranged on a side of the bottom plate 301 away from the deformation joint 1, the fixing device 5 is used to fix the bottom plate 301 on the building, and the fixing device can be arranged at a position between the sliding connection structure and the deformation joint 1. When the cover plate 4 is connected to the base 3, the fixing device 5 is covered on the inner side of the cover plate 4, so that the outer side of the cover plate 4 is smoother.

[0030] In implementation, the above-mentioned sliding connection structure may include a slide groove 6 fixedly connected to the base plate 301 and a sliding portion 7 arranged on both sides of the cover plate 4. The slide groove 6 is arranged on the side of the base plate 301 away from the deformation joint 1. The sliding portion 7 is inserted into the slide groove 6 and slides in the slide groove 6 along the length direction of the deformation joint 1. The width of the slide groove 6 in the left and right direction is greater than the width of the sliding portion 7 in the left and right direction. Therefore, the sliding portion 7 can slide left and right in the slide groove 6. When the width of the deformation joint 1 changes due to temperature changes, the base 3 and the cover plate 4 can slide in the left and right direction.

[0031] Specifically, the above-mentioned slide groove 6 can be a rectangular groove with a rectangular cross-section and the slide groove 6 extends along the length direction of the deformation joint 1.

When in use, the bottom plate 301 with the rectangular groove is fixed to the building, and then the cover plate 4 with the folded edge is slid into one end of the rectangular groove for connection.

[0032] During implementation, since the slide groove 6 is a rectangular groove, there is a certain height difference between the side of the slide groove 6 away from the building and the outer side of the cover plate 4. There will be a groove above the cover plate 4 between the two slide grooves 6. A rubber plate 8 can be arranged in the groove.

The left and right edges of the V-shaped aluminum plate 9 are located below the base 3. Waterproof sealant can be set between the bottom of the V-shaped aluminum plate 9 and the ground, between the top of the V-shaped aluminum plate 9 and the waterproof layer 10, and between the waterproof layer 10 and the base 3.
