Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and in particular to a fixing device for a water-stop copper sheet. Background Art

[0002] In the construction of water conservancy projects, such as flood discharge and sand discharge tunnels, energy dissipation steps must be constructed in stages and cannot be poured continuously. In order to prevent water from seeping into the construction joint between the upper concrete structure and the lower concrete structure, water-stop copper sheets are used for anti-seepage. The water-stop copper sheet is in sheet form, including a U-shaped nose in the middle and water-stop flange plates on both sides. During the construction of the concrete structure, the water-stop copper sheet will be pre-embedded in the concrete structure constructed earlier, and one side flange plate of the water-stop copper sheet will be pre-embedded in the concrete structure constructed earlier, and the other side flange plate will be embedded in the concrete structure constructed later when the concrete structure constructed later is constructed.

[0003] Since the construction interval between the early concrete structure and the later concrete structure is relatively long, the water-stop copper sheets exposed outside the early concrete structure are easily bruised and damaged, and are difficult to repair. Once the water-stop copper sheets are bruised and damaged, the anti-seepage effect will be greatly reduced. Therefore, protecting the exposed water-stop copper sheets plays an important role in maintaining the quality of the anti-seepage system of the water conservancy project.

[0004] In the prior art, most prefabricated wooden boxes or iron boxes are used to wrap the water-stop copper sheets for protection. However, the prefabricated wooden boxes or iron boxes need to be customized, have complex structures, and are time-consuming and labor-intensive to install and disassemble, and have high costs. Summary of the invention

[0005] In order to solve the technical problem that in the prior art, most prefabricated wooden boxes or iron boxes are used to wrap the water-stop copper sheets for protection, but the prefabricated wooden boxes or iron boxes need to be customized, have complex structures, are time-consuming and labor-intensive to install and disassemble, and have high costs, the present invention provides a fixing device for the water-stop copper sheets.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A fixing device for a water-stop copper sheet comprises a supporting structure, wherein the supporting structure comprises two connecting sheets, the two connecting sheets are respectively located on both sides of the water-stop copper sheet in a vertical direction, the connecting sheets are detachably connected to a concrete structure, the two connecting sheets are connected via a fixing structure, the fixing structure is U-shaped, and the two ends of the U-shaped fixing structure are respectively connected to one side of the two connecting sheets away from the concrete structure; a plurality of fixing devices are installed on the side of the water-stop copper sheet pre-embedded in the concrete structure, and all the fixing devices are arranged along the length direction of the water-stop copper sheet.

[0008] By adopting the above-mentioned structural scheme, all the connecting plates are installed on the sides of the pre-buried water-stop copper plates of the concrete structure, and arranged on the upper and lower sides of the water-stop copper plates, and then all the U-shaped fixed structures are installed, and the exposed water-stop copper plates are encircled by the U-shaped fixed structures, and the exposed water-stop copper plates are protected in the U-shaped space of the U-shaped fixed structure. The U-shaped fixed structure can withstand some external interference damage, such as collisions with larger construction facilities, and the side of the U-shaped fixed structure is a smooth arc, which can improve construction safety. The present invention has a simple structure, is easy to install, saves time and effort, and is suitable for concrete structures of various sizes, does not require customization, and has low cost. When the next section of the concrete structure is to be poured, the upper cover plate, the lower cover plate and the side cover plate are taken down together, and then the U-shaped fixed structure and the connecting plates are removed in turn, which is easy to remove and saves time and effort.

[0009] As a preferred implementation method of a fixing device for a water-stop copper sheet, a first reserved hole is opened on the side of the water-stop copper sheet embedded in the concrete structure, and a connecting hole corresponding to the first reserved hole is opened on the connecting sheet, and the connecting hole is connected to the first reserved hole by a fastening bolt.

[0010] The above structural solution is adopted, and the installation is reliable and the cost is low.

[0011] As a preferred implementation of a fixing device for a water-stop copper sheet, two ends of the U-shaped fixing structure are detachably connected to the sides of the two connecting plates away from the concrete structure.

[0012] The above structural solution is adopted to facilitate installation and disassembly, reduce the installation accuracy required for integrated installation, and improve the fault tolerance during installation.

[0013] As a preferred implementation of a fixing device for a water-stop copper sheet, outer sides of two flange plates of the water-stop copper sheet are covered with rubber skin.

[0014] The above structural solution can extend the service life of the water-stop copper sheet, improve the waterproof effect, and enhance the clamping force between the concrete and the water-stop copper sheet.

[0015] As a preferred implementation of a fixing device for a water-stop copper sheet, the fixing structure is a hollow structure, and the material of the fixing structure is metal.

[0016] By adopting the above structural solution, the weight of the fixed structure is lighter, the damage to the concrete structure is reduced, the cost is lower, and the structural strength can also meet the requirements.

[0017] As a preferred implementation method of a fixing device for a water-stop copper sheet, all the fixing structures have the same horizontal height, an upper cover plate is provided above the fixing structure, and the length of the upper cover plate extends along the length direction of the water-stop copper sheet, and a lower cover plate is provided below the fixing structure, and the length of the lower cover plate extends along the length direction of the water-stop copper sheet; a side cover plate is connected between the upper cover plate and the lower cover plate.

[0018] By adopting the above structural solution, the upper cover plate, the lower cover plate and the side cover plate can provide more comprehensive protection for the water-stop copper sheet exposed to the outside.

[0019] As a preferred implementation method of a fixing device for a water-stop copper sheet, several connecting plates below the water-stop copper sheet are connected to a limiting structure, the limiting structure is located on the side of the connecting plate away from the concrete structure, the limiting structure and the fixing structure are horizontally arranged, a limiting gap is provided between the limiting structure and the fixing structure, and the lower cover plate is located in the limiting gap.

[0020] With the above structural solution, the limiting structure can support and limit the positions of the upper cover plate, the lower cover plate and the side cover plate, thereby preventing the upper cover plate, the lower cover plate and the side cover plate from shifting or even sliding off the fixed structure.

[0021] As a preferred implementation of a fixing device for a water-stop copper sheet, the limiting structure is a rod-shaped structure or a plate-shaped structure.

[0022] By adopting the above structural solution, the limit structure has a relatively simple structure, low cost and is easy to install.

[0023] As a preferred implementation of a fixing device for a water-stop copper sheet, the limiting structure is a U-shaped structure, and both ends of the U-shaped limiting structure are respectively connected to two connecting sheets of the same supporting structure.

[0024] With the above structural solution, the U-shaped limiting structure can more comprehensively support and limit the positions of the upper cover, lower cover and side cover. The two ends of the U-shaped limiting structure can be fixedly connected or detachably connected to the two connecting pieces of the same supporting structure.

[0025] As a preferred implementation of a fixing device for a water-stop copper sheet, the connecting sheet abuts against the surface of the water-stop copper sheet.

[0026] By adopting the above structural solution, the connecting piece can clamp the water-stop copper sheet, thereby reducing the deformation of the water-stop copper sheet.

[0027] The beneficial effects of the present invention are:

[0028] All the connecting plates are installed on the sides of the pre-buried water-stop copper plates of the concrete structure, and arranged on the upper and lower sides of the water-stop copper plates, and then all the U-shaped fixed structures are installed, and the exposed water-stop copper plates are encircled by the U-shaped fixed structures, and the exposed water-stop copper plates are protected in the U-shaped space of the U-shaped fixed structure. The U-shaped fixed structure can withstand some external interference damage, such as collisions with larger construction facilities, and the side of the U-shaped fixed structure is a smooth arc, which can improve construction safety. The present invention has a simple structure, is easy to install, saves time and effort, and is suitable for concrete structures of various sizes, does not require customization, and has low cost. When the next section of the concrete structure is to be poured, the upper cover plate, the lower cover plate and the side cover plate are taken down together, and then the U-shaped fixed structure and the connecting plates are removed in turn, which is easy to remove and saves time and effort.
