Description

Technical Field

[0001] This technical solution belongs to the field of municipal engineering in the construction industry, specifically a water-stop steel plate fixing device. Background Technology

[0002] During the construction of integrated utility tunnel projects, it is usually necessary to install water-stop steel plates at horizontal construction joints to ensure the waterproofing performance of the joints. The existing construction method is generally as follows: after the wall reinforcement is tied, the water-stop steel plate is placed in the designated position, and then the water-stop steel plate is fixed to the steel mesh by welding.

[0003] However, the above construction method has significant shortcomings. First, since the installation of the waterstop steel plate must be carried out after the reinforcement binding is completed, the installation process will disturb the completed reinforcement mesh, easily leading to deviations in the reinforcement spacing, which does not meet the design requirements. Second, the waterstop steel plate is fixed to the reinforcement mesh by welding; once the position deviates, subsequent adjustments are difficult, making it hard to ensure the fit between the waterstop steel plate and the construction joint. Third, the waterstop steel plate is greatly affected by the displacement of the reinforcement mesh during construction, making it difficult to control its flatness and straightness, thus affecting the waterproofing quality of the pipe gallery construction joint.

[0004] Therefore, how to provide a technical solution that facilitates the installation of waterstop steel plates and ensures their accurate positioning has become an urgent technical problem to be solved in this field. Summary of the Invention

[0005] During the construction of integrated utility tunnels, waterstop steel plates are typically installed at horizontal construction joints to ensure the waterproofing performance of the joints. Current construction methods generally involve placing the waterstop steel plate in the designated position after the wall panel reinforcement is tied, and then fixing it to the reinforcing mesh by welding. However, this process has several shortcomings: because the installation of the waterstop steel plate is carried out after the reinforcement is tied, it easily disturbs the already tied reinforcing mesh, leading to misalignment of the reinforcement spacing and failure to meet design specifications; furthermore, the fixing of the waterstop steel plate depends on the position of the reinforcing mesh, and once installation deviations occur, subsequent adjustments are difficult, making it hard to guarantee the flatness and straightness of the waterstop steel plate.

[0006] The inventors discovered that the root cause of the above problems lies in the lack of an independent fixing device for the waterstop steel plate in current construction techniques. The waterstop steel plate can only be fixed by attaching it to the reinforcing mesh. Due to limitations in construction sequence and working space, the waterstop steel plate must be installed after the reinforcing bars are tied, causing the installation quality of the waterstop steel plate and the quality of the reinforcing bar tying to mutually restrict each other. To compensate for deviations, construction workers have to adjust the position of the waterstop steel plate and the reinforcing mesh multiple times, increasing the complexity of the process, construction time, and reducing construction efficiency.

[0007] To address the aforementioned problems, this application discloses a waterstop steel plate fixing device. This device, through the use of independent fixing brackets, ensures the accurate positioning of the waterstop steel plate during construction positioning and layout, allowing the waterstop steel plate to be pre-installed in the designated position before rebar tying, thus avoiding interference with subsequent rebar tying. Simultaneously, this device makes the installation position of the waterstop steel plate more stable and reliable, significantly improving the waterproofing performance at construction joints. Compared with traditional methods, the technical solution of this application not only simplifies the construction process and reduces the number of manual adjustments, but also improves the installation accuracy and construction quality of the waterstop steel plate.

[0008] In order to solve the above-mentioned technical problems, the present invention discloses the following technical solution; A water-stop steel plate fixing device, comprising: Water-stop steel plate clamping mechanism; the water-stop steel plate clamping mechanism includes: A rectangular frame; the rectangular frame is equipped with a clamping device; Clamping device: The clamping component of the clamping device is a combined waterstop steel plate clamp made according to the size of the waterstop steel plate; Clamping mechanism support frame: The clamping mechanism support frame is located below the rectangular frame to support the rectangular frame. The clamping mechanism support frame is also equipped with a height adjustment mechanism, which allows the height of the waterstop steel plate clamping mechanism to be adjusted.

[0009] Furthermore, the clamping device is slidably connected to the rectangular frame, so that the clamping device can be horizontally moved to the corresponding position on the rectangular frame and then locked.

[0010] Furthermore, the clamping device is provided with a sliding locking block, and the clamping device is slidably connected to the rectangular frame through the sliding locking block, so that the clamping device can move horizontally on the rectangular frame.

[0011] Furthermore, the clamping device includes a first clamping part and a second clamping part. The first clamping part is a long strip plate with an obtuse angle cross-section. Sliding locking blocks are fixed at both ends of the first clamping part. The sliding locking blocks at both ends of the first clamping part are slidably connected to two parallel sides of the rectangular frame, so that the first clamping part can move horizontally on the rectangular frame. The second clamping part is a long strip plate with an obtuse angle cross-section. Sliding locking blocks are fixed at both ends of the second clamping part. The sliding locking blocks at both ends of the second clamping part are slidably connected to two parallel sides of the rectangular frame, so that the second clamping part can move horizontally on the rectangular frame. The contact surfaces of the first clamping part and the second clamping part are in contact.

[0012] Furthermore, the angle between the cross sections of the first clamping part and the second clamping part is consistent with the angle of the bend in the waterstop steel plate.

[0013] Furthermore, the clamping mechanism support frame includes four support rods located at the four corners of the rectangular frame, and the support rods are equipped with telescopic mechanisms.

[0014] Furthermore, each of the four support rods is equipped with a tripod, which is connected to the support rod via a second sliding locking block as a telescopic mechanism, allowing the height of the clamping mechanism support frame to be adjusted by changing the position of the connection between the tripod and the support rod.

[0015] Compared with the prior art, the present invention has the following outstanding advantages: Compared with the prior art, the present invention has the following beneficial effects: 1. This device, by setting up an independent fixing bracket for the water-stop steel plate, enables the water-stop steel plate to be accurately installed before the rebar tying process, avoiding the problem of disturbance to the rebar mesh caused by post-installation in traditional processes, and fundamentally ensuring the independence of the rebar tying quality and the water-stop steel plate installation quality.

[0016] 2. The waterstop steel plate is fixed by a clamping mechanism and a sliding locking block, allowing for flexible position adjustment and reliable locking on the rectangular frame. Construction personnel can quickly adjust the position and angle of the waterstop steel plate according to the construction joint layout, significantly reducing the amount of secondary adjustment work and ensuring that the waterstop steel plate is straight and flat.

[0017] 3. Because the water-stop steel plate can be accurately positioned and remain stable at the construction joint, it avoids displacement, twisting and other situations, thus improving the overall sealing and waterproofing effect of the pipe gallery construction joint.

[0018] The application of this device changes the traditional process that relies on welding and fixing steel mesh, decoupling the installation of waterstop steel plates from the steel bar binding process, simplifying construction steps, shortening the construction period, and improving construction efficiency.

[0019] By reducing repeated adjustments and secondary repairs in the later stages, the waste of labor, materials and machinery is reduced, and the overall construction cost is effectively saved, which has good economic benefits and promotion value. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: A water-stop steel plate fixing device, comprising: Water-stop steel plate clamping mechanism; the water-stop steel plate clamping mechanism includes: Rectangular frame 1; the rectangular frame 1 is equipped with a clamping device; Clamping device: The clamping component of the clamping device is a combined waterstop steel plate clamp made according to the size of the waterstop steel plate; Clamping mechanism support frame: The clamping mechanism support frame is located below the rectangular frame 1 to support the rectangular frame 1. The clamping mechanism support frame is also provided with a height adjustment mechanism so that the height of the waterstop steel plate clamping mechanism can be adjusted through the height adjustment mechanism. The clamping device is provided with a sliding locking block 4. The clamping device is slidably connected to the rectangular frame 1 through the sliding locking block 4, so that the clamping device can be locked after being moved horizontally to the corresponding position on the rectangular frame 1. The clamping device consists of a first clamping part 2 and a second clamping part 3, which are made of two 3mm thick steel plates according to the size of the waterstop steel plate. The first clamping part 2 is a long strip plate with an obtuse angle cross section. Sliding locking blocks 4 are fixed at both ends of the first clamping part 2 (the fixing method can be welding or threaded connection). The sliding locking blocks 4 at both ends of the first clamping part 2 are slidably connected to the two parallel sides of the rectangular frame 1, so that the first clamping part 2 can move horizontally on the rectangular frame 1. The second clamping part 3 is a long strip plate with an obtuse angle cross section. Sliding locking blocks 4 are fixed at both ends of the second clamping part 3. The sliding locking blocks 4 at both ends of the second clamping part 3 are slidably connected to the two parallel sides of the rectangular frame 1, so that the second clamping part 3 can move horizontally on the rectangular frame 1. The contact surfaces of the first clamping part 2 and the second clamping part 3 are in contact. The angle of the cross section of the first clamping part 2 and the second clamping part 3 is consistent with the angle of the bend of the waterstop steel plate.

[0024] The clamping mechanism support frame includes four support rods 5 located at the four corners of the rectangular frame 1. Each support rod 5 is equipped with a telescopic mechanism. Each of the four support rods 5 is equipped with a tripod 6. The tripod 6 is connected to the support rod 5 via a second sliding locking block 7 as a telescopic mechanism, so that the height of the clamping mechanism support frame can be adjusted by changing the position of the connection between the tripod 6 and the support rod 5. Each tripod 8 can be connected to the others via a connecting rod 8, which can be welded or threaded to further reduce the workload of adjusting the height of the device.

[0025] In addition, the utility model discloses the following technical solutions based on the above embodiments; 1. The sliding locking block 4 can be a screw-pressed sliding locking block 4, with the following structure: The screw-pressing sliding locking block 4 includes a block body and a pressing screw. The block body is configured to cooperate with the guide groove of the rectangular frame 1 or the support rod 5, allowing it to slide along the guide groove. The block body is provided with a threaded hole, and the pressing screw is threaded into the threaded hole. When the pressing screw is tightened, its end presses against the guide surface of the rectangular frame 1 or the support rod 5, using friction to achieve locking and fixation. When the pressing screw is loosened, the sliding locking block 4 can slide freely in the guide groove, thereby realizing the adjustment of the clamping component or the support structure.

[0026] 2. The sliding locking block 4 can be a wedge-type sliding locking block 4, with the following structure: The wedge-type sliding locking block 4 includes a sliding block, a wedge-shaped pressure block, and a driving bolt. The sliding block is slidably engaged with the guide groove of the rectangular frame 1 or the support rod 5. The wedge-shaped pressure block is disposed between the sliding block and the guide surface. The driving bolt passes through the sliding block and is connected to the wedge-shaped pressure block. When the driving bolt is tightened, the wedge-shaped pressure block is pushed along the inclined surface, thereby pressing against the guide surface of the rectangular frame 1 or the support rod 5 to form a strong wedge-locking mechanism. When the driving bolt is loosened, the wedge-shaped pressure block retracts, and the sliding block can slide freely in the guide groove to achieve rapid adjustment.

[0027] 3. The sliding lock block 4 can be an eccentric cam-type sliding lock block 4, with the following structure: The eccentric cam-type sliding lock block 4 includes a sliding block, a rotating shaft, and an eccentric cam. The sliding block slides in cooperation with the guide groove of the rectangular frame 1 or the support rod 5. The rotating shaft is rotatably mounted on the sliding block. The eccentric cam is fixed to the rotating shaft and located between the sliding block and the guide surface. When the rotating shaft rotates, the eccentric part of the eccentric cam pushes the sliding block to press against the guide surface, thus locking it. When the rotating shaft rotates to the return position of the eccentric cam, the sliding block is released from the pressing state and can slide and adjust within the guide groove. It is convenient to operate and suitable for occasions requiring frequent adjustments.

[0028] The operating instructions for the water-stop steel plate fixing device of this application are as follows: 1. Construction Preparation Complete the layout work for the construction joints of the pipe gallery according to the construction drawings, and confirm the installation position and size of the waterstop steel plate.

[0029] Move the device to the vicinity of the construction joint and check whether the clamping mechanism, support frame, sliding lock block 4 and other components are intact to ensure that the device is in normal working condition. Place the water-stop steel plate into the clamping mechanism so that its bent part completely matches the contact surface of the first clamping part 2 and the second clamping part 3.

[0030] Bracket placement and height adjustment: The four support rods 5 of the clamping mechanism support frame are placed on the construction ground, and the tripod 6 is deployed for support. After adjusting the sliding locking block 4 at the tripod 6 to a suitable height, lock it so that the height of the support rod 5 can be adjusted through the telescopic mechanism, so that the height of the waterstop steel plate meets the construction elevation of the waterstop steel plate and ensures that the support frame is stable and reliable. After releasing the sliding locking block 4, push the clamping part to move horizontally, adjust the position of the sliding locking blocks 4 at both ends of the clamping part, adjust the horizontal position of the waterstop steel plate, and tighten the locking block after the position of the waterstop steel plate meets the construction requirements to achieve positioning and locking.

[0031] Location verification and fixation: Use measuring tools to check the verticality and straightness of the waterstop steel plate to confirm that it is consistent with the design layout.

[0032] If fine adjustments are needed, the corresponding sliding locking block 4 can be loosened, the position of the clamping part readjusted, and then locked again until the requirements are met.

[0033] Dismantling of equipment and subsequent construction: After the water-stop steel plate is fixed, first keep it in a stable and locked state in the clamping device; After fixing the waterstop steel plate in the construction position using a fixing device (which can be welded steel bars or fixed in the construction position by a bracket of the waterstop steel plate), release the clamping device, remove the fixing bracket and support mechanism, leave the waterstop steel plate in the construction position, and then carry out the binding of the steel mesh and concrete pouring.
