Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a simple deformation joint cover plate structure. Background Art

[0002] At present, expansion joints are often required in building structures. Expansion joints can absorb or buffer the stress caused by factors such as temperature difference, settlement and vibration, and reduce the deformation and cracking of buildings. At the same time, expansion joints are also the "weak parts" of building waterproofing. The existing expansion joint treatment method is to make a cover plate on site through a concrete cover plate, steel plate or iron sheet, cover the expansion joint with the cover plate, and embed sealant in the expansion joint. However, these methods have a relatively complicated construction process, and the overlap of different materials will produce more gaps, which is not only unsightly, but also has a general waterproof effect. Once a leak occurs, it will affect the appearance and use of the building structure. At the same time, the complex construction process also brings a lot of trouble to the repair process. Therefore, the expansion joint sealing and leakage prevention work must not only achieve good results, but also take into account the difficulty of later repairs. Utility Model Content

[0003] The utility model aims to provide a simple deformation joint cover plate structure to solve the technical problems described in the background technology.

[0004] In order to achieve the above technical purpose, the utility model adopts the following technical solutions:

[0005] A simple deformation joint cover plate structure comprises a sealing cover plate, which is made of metal material and comprises an integrally connected groove portion and a flange portion, wherein the width of the groove portion matches the width of the deformation joint, the groove portion is embedded in the deformation joint, and the groove portion is filled with a flexible supporting material, and the groove walls on both sides of the groove portion extend along the structural anti-ridges on both sides of the deformation joint in a direction away from the deformation joint to form a flange portion, and the flange portion is sealed and fixed on the structural anti-ridge.

[0006] Preferably, a folded edge portion bent toward one side of the structural counter-ridge is provided at the end of the flange portion, and the folded edge portion is embedded in the structural counter-ridge and is sealed and fixed to the structural counter-ridge by a sealant.

[0007] Preferably, the flexible supporting material is a polyethylene rod, the polyethylene rod is embedded in the groove portion, and the gap between the polyethylene rod and the wall plate of the groove portion is filled with sealant.

[0008] Preferably, the sealing cover plate is made of stainless steel, galvanized steel or aluminum alloy.

[0009] Preferably, the groove portion is embedded in the deformation joint to a depth of not less than 60 mm, and the folded edge portion is embedded in the structural anti-ridge to a depth of not less than 10 mm.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model has a simple structure and ingenious design. The sealing cover plate can be deformed along with the structure by embedding the groove portion of the deformation joint, thereby ensuring the sealing and water-stopping performance of the sealing cover plate. Moreover, the flexible supporting material embedded in the groove portion can enhance the sealing cover plate's resistance to plastic deformation, thereby avoiding the groove portion from being excessively squeezed to produce plastic deformation that cannot be restored, resulting in water leakage problems in the later stage. At the same time, the utility model is simple to process and manufacture, and is very convenient to install, construct and maintain in the later stage. It can be applied to the sealing treatment of various forms of horizontal deformation joints and vertical deformation joints, and has strong applicability. BRIEF DESCRIPTION OF THE DRAWINGS

The embodiments are only used to explain the present invention and are not intended to limit the scope of the present invention. Figure 1-3 , the preferred embodiments of the utility model are further described in detail:

[0020] like Figure 1-2As shown, a preferred simple deformation joint cover plate structure of the utility model includes a sealing cover plate 1, which is made of metal material and includes a groove portion 101, a flange portion 102 and a folded edge portion 103 that are connected in one piece. The groove portion 101 is U-shaped. The U-shaped groove portion 101 improves the deformation ability of the sealing cover plate 1, and can deform with the structure without being constrained. The width of the groove portion 101 matches the width of the deformation joint 5. The groove portion 101 is embedded in the deformation joint 5. In order to ensure that the groove portion 101 can be effectively embedded in the deformation joint 5 so that the sealing cover plate 1 can be deformed synchronously with the structure, the depth of the groove portion 101 embedded in the deformation joint 5 should not be less than 60 mm. At the same time, the specific width of the groove portion 101 needs to be determined according to the width of the deformation joint 5. In order to ensure that it can be easily inserted into the joint during installation, 150 mm needs to be reserved between each side of the groove portion 101 and the side wall of the deformation joint 5. The groove portion 101 is filled with a flexible supporting material 2, and the flexible supporting material 2 is preferably a deformable polyethylene rod, the polyethylene rod is embedded in the groove portion 101, and the gap between the polyethylene rod and the wall plate of the groove portion 101 is filled with a sealant 3, the sealant 3 can ensure that the polyethylene rod is tightly combined with the groove portion 101 to prevent the polyethylene rod from being accidentally squeezed out, and the groove walls on both sides of the groove portion 101 extend along the structural anti-ridges 4 on both sides of the deformation seam 5 in a direction away from the deformation seam 5 to form a flange portion 102 that fits on the structural anti-ridge 4, and the end of the flange portion 102 is provided with a folding portion 103 bent toward one side of the structural anti-ridge 4, the folding portion 103 is embedded in the structural anti-ridge 4 and is sealed and fixed on the structural anti-ridge 4 by the sealant 3, and the depth of the folding portion 103 embedded in the structural anti-ridge 4 is not less than 10 mm to ensure that the folding portion 103 is effectively fixed on the structural anti-ridge 4 without relative displacement with the structural anti-ridge 4;

[0021] Since the sealing cover plate 1 is mainly used for waterproofing, the sealing cover plate 1 needs to have sufficiently good anti-rust performance. Therefore, the sealing cover plate 1 is preferably made of stainless steel, galvanized steel or aluminum alloy.

[0022] The specific construction method of the utility model is as follows, which mainly includes the following steps:

[0023] Step 1: Clean the base layer at the position of expansion joint 5;

[0024] Step 2: Positioning and laying out the sealing cover plate 1, as shown in Figure 3 As shown, the sealing cover plates 1 at the horizontal deformation joint and the vertical deformation joint are sealed and connected by welding to ensure the sealing and water-stopping performance;

[0025] Step 3: The folded edges 103 at both ends of the sealing cover plate 1 are embedded in the structural anti-ridge 4, and the gaps are filled with sealant 3 to prevent leakage at the "weak position". The grooves for accommodating the folded edges 103 can be set in advance during the pouring stage of the structural anti-ridge 4, or can be set by excavation after positioning and laying out;

[0026] Step 4: embed a deformable polyethylene rod into the groove 101 and fill the groove with a sealant 3;

[0027] Step 5: Construct waterproof layer 6 and upper part according to the design drawings.
