Description

Technical Field

[0001] This utility model relates to the field of building construction, and more specifically, to a waterproofing structure for expansion joints in basement shear walls. Background Technology

[0002] Currently, when building a basement, in order to prevent cracks from appearing in the shear walls due to long-term thermal expansion and contraction, expansion joints are usually installed in the shear walls of the basement.

[0003] However, currently, expansion joints are simply covered with a layer of waterstop or waterproof structural adhesive after construction, resulting in poor waterproof performance. In addition, because it is easy to install the waterstop, the frame structure of the expansion joint is not easy to install, thus increasing the difficulty of construction for workers.

[0004] Therefore, it is necessary to propose a waterproofing structure for expansion joints in basement shear walls to solve the above problems. Utility Model Content

[0005] To overcome at least one of the defects (deficiencies) of the prior art, this utility model provides a waterproofing structure for expansion joints in basement shear walls.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a waterproof treatment structure for expansion joints of basement shear walls, including a supporting positioning outer frame, a supporting positioning inner frame, and a snap-fit ​​positioning device;

[0007] The outer support positioning frame is disposed outside the inner support positioning frame, and the outer support positioning frame and the inner support positioning frame are connected by a plurality of interconnected arc-shaped connecting pieces.

[0008] The snap-fit ​​locator is located on the inner side of the supporting positioning inner frame, and the snap-fit ​​locator is equipped with a water-stop strip;

[0009] The inner support positioning frame has a recessed cavity containing waterproof structural adhesive, which is separate from the waterstop. Since the outer and inner support positioning frames are connected by multiple interconnected arc-shaped connecting pieces, during installation of the waterproofing structure for the basement shear wall expansion joints, if the expansion joint is wide, its width can be increased by tapping the arc-shaped connecting pieces; if the expansion joint is narrow, the curvature of the connecting pieces can be compressed further. This facilitates the installation of the waterproofing structure. Furthermore, to better address the waterproofing issue, the simultaneous use of the waterstop and waterproof structural adhesive provides simultaneous waterproofing, thereby enhancing the waterproofing effect of the basement shear wall.

[0010] Furthermore, the snap-fit ​​locator includes a first fixed snap-fit ​​groove, a second fixed snap-fit ​​groove, and a snap-fit ​​sliding block;

[0011] The first fixing slot and the second fixing slot are sequentially arranged on the inner side of the support positioning inner frame;

[0012] A connecting protrusion is provided between the first fixing slot and the second fixing slot.

[0013] The snap-fit ​​sliding block is disposed on the first fixed snap-fit ​​groove and / or the second fixed snap-fit ​​groove. The snap-fit ​​sliding block is connected to the waterstop. By sequentially disposing of the first fixed snap-fit ​​groove and the second fixed snap-fit ​​groove on the inner side of the supporting positioning inner frame, the snap-fit ​​sliding block can be disposed on the first fixed snap-fit ​​groove and / or the second fixed snap-fit ​​groove as needed. The setting of the connecting protrusion strengthens the connection strength between the first fixed snap-fit ​​groove and the second fixed snap-fit ​​groove.

[0014] Furthermore, a sealing gasket is provided at the connection between the snap-fit ​​sliding block and the first fixed snap-fit ​​groove and / or the second fixed snap-fit ​​groove. The sealing gasket facilitates the installation of the snap-fit ​​sliding block with the first fixed snap-fit ​​groove and / or the second fixed snap-fit ​​groove, while also providing a sealing function.

[0015] Furthermore, the inner side of the supporting positioning inner frame is provided with reinforcing ribs, which effectively enhances the connection strength between the supporting positioning inner frame and the arc-shaped connecting piece.

[0016] Furthermore, the outer support positioning frame, inner support positioning frame, arc-shaped connecting piece, reinforcing rib, and concave cavity are an integrated structure. This integrated structure effectively simplifies the overall structure of the waterproofing treatment for expansion joints in basement shear walls.

[0017] Furthermore, the outer support positioning frame, the inner support positioning frame, the arc-shaped connecting piece, the reinforcing rib, and the concave cavity are all made of metal or alloy materials. In practical applications, metal or alloy materials can be selected as needed, which are all readily apparent to those skilled in the art.

[0018] Furthermore, the waterproof structural adhesive is a neutral silicone waterproof structural adhesive. In practical applications, other waterproof materials can also be used as substitutes, all of which are readily apparent to those skilled in the art.

[0019] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0020] The waterproofing structure for expansion joints in basement shear walls disclosed in this utility model connects the outer and inner support positioning frames via multiple interconnected arc-shaped connecting pieces. Therefore, during installation, if the expansion joint is wide, the arc-shaped connecting pieces can be tapped to widen it to some extent; if the expansion joint is narrow, the curvature of the connecting pieces can be compressed further. This facilitates the installation of the waterproofing structure. Furthermore, to better address the waterproofing issue, the simultaneous application of waterstops and waterproof structural adhesive provides simultaneous waterproofing, thereby enhancing the waterproofing effect of the basement shear wall.

Detailed Implementation

[0027] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0029] like Figure 1-5 As shown, a waterproofing structure for expansion joints in basement shear walls includes a supporting positioning outer frame 1, a supporting positioning inner frame 2, and a snap-fit ​​locator 3. The supporting positioning outer frame is located outside the supporting positioning inner frame, and the outer and inner frames are connected by multiple interconnected arc-shaped connecting pieces 4. The snap-fit ​​locator is located inside the supporting positioning inner frame and has a waterstop 5. The supporting positioning inner frame has a recessed cavity 6, and a waterproof structural adhesive 7 is placed inside the recessed cavity. The waterproof structural adhesive and the waterstop are separate. The expansion joints of the basement shear walls are connected by multiple interlocking arc-shaped connecting pieces. Therefore, during the installation of the waterproofing structure for the expansion joints of the basement shear walls, if the expansion joints are wide, the width can be increased to a certain extent by tapping the arc-shaped connecting pieces. If the expansion joints are narrow, the curvature of the multiple arc-shaped connecting pieces can be compressed again, thus facilitating the installation of the waterproofing structure for the expansion joints of the basement shear walls. In order to better solve the waterproofing problem, waterstops and waterproof structural adhesives are installed simultaneously, which can play a waterproofing role at the same time, thereby enhancing the waterproofing effect of the basement shear walls.

[0030] In this utility model, the snap-fit ​​positioning device includes a first fixed snap-fit ​​groove 8, a second fixed snap-fit ​​groove 9, and a snap-fit ​​sliding block 10; the first fixed snap-fit ​​groove and the second fixed snap-fit ​​groove are sequentially arranged on the inner side of the supporting positioning inner frame; a connecting protrusion 13 is provided between the first fixed snap-fit ​​groove and the second fixed snap-fit ​​groove; the snap-fit ​​sliding block is disposed on the first fixed snap-fit ​​groove and / or the second fixed snap-fit ​​groove, and the snap-fit ​​sliding block is connected to the waterstop. This is achieved by sequentially arranging the first fixed snap-fit ​​groove and the second fixed snap-fit ​​groove on the supporting positioning inner frame. The inner side of the inner frame allows the snap-fit ​​sliding block to be installed on the first fixed snap-fit ​​groove and / or the second fixed snap-fit ​​groove as needed. The connection protrusion strengthens the connection between the first fixed snap-fit ​​groove and the second fixed snap-fit ​​groove. A sealing gasket 11 is provided at the connection between the snap-fit ​​sliding block and the first fixed snap-fit ​​groove and / or the second fixed snap-fit ​​groove. The sealing gasket facilitates the installation of the snap-fit ​​sliding block and the first fixed snap-fit ​​groove and / or the second fixed snap-fit ​​groove, while also providing a sealing function.

[0031] In addition, a reinforcing rib 12 is provided on the inner side of the inner support positioning frame. The reinforcing rib effectively strengthens the connection strength between the inner support positioning frame and the arc-shaped connecting piece. The outer support positioning frame, inner support positioning frame, arc-shaped connecting piece, reinforcing rib, and concave cavity are an integrated structure. The integrated outer support positioning frame, inner support positioning frame, arc-shaped connecting piece, reinforcing rib, and concave cavity effectively simplify the overall structure of the waterproof treatment structure for the expansion joint of the basement shear wall. The outer support positioning frame, inner support positioning frame, arc-shaped connecting piece, reinforcing rib, and concave cavity are all made of metal or alloy materials. In practical applications, metal or alloy materials can be selected as needed, which are all easily conceived by those skilled in the art. In this utility model, the waterproof structural adhesive is a neutral silicone waterproof structural adhesive. In practical applications, other waterproof materials can also be used as substitutes, which are all easily conceived by those skilled in the art.

[0032] Example

[0033] In this embodiment, since an outer support positioning frame and an inner support positioning frame are provided, and the waterstop is set on the inner support positioning frame, and the outer support positioning frame and the inner support positioning frame are connected by multiple interconnected arc-shaped connecting pieces, when installing the waterproof treatment structure for the expansion joint of the basement shear wall, if the expansion joint is wide, its width can be widened to a certain extent by tapping the arc-shaped connecting pieces; if the expansion joint is narrow, the curvature of the multiple arc-shaped connecting pieces can be compressed again, thereby facilitating the installation of the waterproof treatment structure for the expansion joint of the basement shear wall. In order to better solve the waterproofing problem, the simultaneous setting of the waterstop and waterproof structural adhesive can play a waterproofing role at the same time, thereby enhancing the waterproof treatment effect of the basement shear wall.

[0034] The positional relationships described in the figures are for illustrative purposes only and should not be construed as limiting this patent. Clearly, the above embodiments of this utility model are merely examples to clearly illustrate the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
