[0002] As a commonly used water-stopping and water-isolating measure for construction joints of underground structural projects, the embedded steel-edge rubber waterstop has played a huge role in preventing leakage and dislocation of construction joints. In view of the widespread phenomenon of underground structure water leakage in the field of engineering construction, more and more underground projects have made the creation of "leakage-free structures" the primary goal of the project. In order to maximize its water-stopping and water-isolating functions, the embedded rubber waterstop should be accurately positioned and avoid drilling during installation. At the same time, it must have the ability to resist dislocation and concrete impact and floating, which puts higher and higher requirements on the installation quality of the embedded steel-edge rubber waterstop. Summary of the invention

[0003] The purpose of the utility model is to provide a U-groove positioning device for a wooden formwork of a centrally embedded steel-edge rubber waterstop based on the above-mentioned deficiencies of the prior art.

[0004] The purpose of this utility model is achieved by the following technical solutions:

[0005] A U-shaped groove positioning device for a wooden mold of a centrally embedded steel-edge rubber waterstop is used to fix the centrally embedded steel-edge rubber waterstop on the main structure steel bars, and is characterized in that: it includes a main keel, and the main keel is connected and fixed to the main structure steel bars; the main keel includes an upper keel and a lower keel, and the lower keel is provided with a U-shaped groove that matches the centrally embedded steel-edge rubber waterstop, and the upper keel is provided with a clamp, and the clamp and the upper keel form a sliding fit, and the clamp on the upper keel is used to fix the centrally embedded steel-edge rubber waterstop at the U-shaped groove position of the lower keel.

[0006] The two ends of the upper keel and the lower keel are respectively fixed to the main structure steel bars by binding pieces.

[0007] The clamp comprises symmetrically arranged clamping members on the left and right sides, and the clamping members on the two sides are connected and fixed to form an integral structure by connecting positioning screws.

[0008] A wooden mold is arranged between the clamp and the embedded steel-edge rubber waterstop.

[0009] A rubber pad is arranged between the wooden mold and the embedded steel-edge rubber waterstop.

[0011] The advantages of the utility model are:

[0012] 1) The wooden formwork-U-shaped groove positioning device avoids damage to the rubber body and galvanized steel edge of the waterstop during installation. No holes need to be drilled during the installation of the waterstop, which further ensures the sealing and water-stopping effect of the construction joint.

[0013] 2) The waterstop is clamped flat and tightened at one time through the wooden mold-U-groove positioning device, without the need for extrusion, flattening and straightening processes. At the same time, the device is connected into a whole through wire binding, screw locking and clamp clamping, which is easy to disassemble and assemble, thereby improving the installation efficiency of the waterstop.

[0014] 3) The waterstop is connected to the main reinforcement of the main structure through the upper main keel and wooden formwork-U-shaped groove to form an integral force system, avoiding obvious interference from other construction activities, which is conducive to the central positioning of the waterstop and significantly improves the anti-floating ability of the waterstop.

[0018] Example: Figure 1 As shown, the U-groove positioning device of the wooden formwork of the embedded steel-edge rubber waterstop in this embodiment is used to fix the embedded steel-edge rubber waterstop 7 to the main structure steel bar 1, and the main structure steel bar 1 can be a vertically arranged main reinforcement.

[0019] Specifically, if Figure 1 As shown, the positioning device in this embodiment includes a main keel 3, which includes an upper and a lower keel, wherein the two ends of the upper keel are tied to the main structure steel bar 1 by wire 11, and the two ends of the lower keel are tied to the main structure steel bar 1 by wire 10, so as to prevent the concrete pouring from causing the floating of the embedded steel edge rubber waterstop 7. In the height direction, the upper keel and the lower keel are arranged on the same main structure steel bar 1 at a certain distance to reserve a fixed installation space for the embedded steel edge rubber waterstop 7.

[0020] like Figure 1 As shown, a clamp 4 is provided on the upper keel, and the clamp 4 includes two symmetrically arranged clamping parts, which are connected and fixed by a positioning screw 5 to form a whole, so as to fix the central embedded steel edge rubber water stop 7. In this embodiment, the screwing locking and unlocking after clamping can be completed by the positioning screw 5, and the clamping degree of the central embedded steel edge rubber water stop 7 can be adjusted by different screwing degrees. The clamp 4 is sleeved on the upper keel through the middle opening, so that it has the function of freely adjusting the spacing left and right, so that the spacing of the clamp can be freely adjusted according to the position of the lower wooden mold 6, which is conducive to the fixation of the position of the wooden mold 6.

[0021] In this embodiment, a wooden mold 6 is provided between the clamp 4 and the embedded steel-edge rubber waterstop 7, which is used to clamp the embedded steel-edge rubber waterstop 7 to prevent the waterstop from being twisted. A rubber pad 8 is pasted on the inner side of the wooden mold 6 to prevent the wood from directly contacting the rubber surface of the waterstop, thereby protecting the waterstop.

[0022] like Figure 1 As shown, a U-shaped groove 2 is provided on the lower keel, and the position of the U-shaped groove 2 corresponds to the design position of the embedded steel-edge rubber waterstop 7. A rubber pad 9 is installed between the embedded steel-edge rubber waterstop 7 and the U-shaped groove 2 to protect the galvanized steel edge of the embedded steel-edge rubber waterstop 7 from damage, which is beneficial to improving the durability of the main structure.

[0023] In this embodiment, the entire positioning device is connected in a non-drilling manner, and its function is to ensure the installation quality of the waterstop, especially to ensure that the waterstop is flat, straight, and centrally positioned, and has excellent resistance to concrete impact during concrete pouring, avoiding floating and dislocation, thereby improving the sealing and water-stopping performance of the construction joint.

[0024] In the specific implementation of this embodiment: the U-shaped groove of the lower keel is made according to the model of the steel-edge rubber waterstop, the groove depth is not greater than the construction joint elevation, and the groove width is not less than the thickest part of the waterstop. The steel-edge rubber waterstop can be freely inserted into the U-shaped groove, while preventing the U-shaped groove from being exposed for too long and corroded and rusted, which is beneficial to improving the casting quality of reinforced concrete structures.

[0025] When used, this embodiment includes the following construction steps:

[0029] 4) Insert the bottom of the buried steel-edge rubber waterstop 7 into the U-shaped groove 2, place the galvanized steel edge on the rubber pad 9, and check whether the center position and buried depth of the waterstop are correct.

[0030] 5) The operator places the wooden mold 6 with the rubber pad 8 on both sides of the upper part of the embedded steel-edge rubber waterstop 7, and the rubber pad 8 and the embedded steel-edge rubber waterstop 7 are the contact surfaces.

[0031] 6) Place the upper keel with the clamp 4 above the water stop, and use temporary fixing measures to facilitate the next step of construction.

[0032] 7) Adjust the clamp 4 on one side to the clamping position according to the position of the wooden mold 6, and screw the positioning screw 5 on the same side to lock it.

[0033] 8) According to the position of the wooden mold 6, the spacing of the clamps 4 on the other side is adjusted and locked by the positioning screws 5 on the same side. The wooden mold 6 is clamped to ensure that the embedded steel-edged rubber waterstop 7 is flat, straight and not twisted.

[0034] 9) The two ends of the upper keel are connected to the main reinforcement 1 of the main structure by iron wire 11 to form a whole, so as to prevent the embedded steel-edge rubber waterstop 7 from floating up during the concrete pouring process and facilitate its removal later.

[0035] Working principle: The wooden formwork-U-shaped groove positioning device is used to connect the embedded steel-edged rubber waterstop with the main reinforcement of the main structure into a whole, thereby improving the overall anti-dislocation ability; the device connection mainly adopts clamp clamping, screw locking and wire binding to avoid drilling, ensure that the waterstop is flat and straight, and improve the waterproof and water-stopping performance of the construction joint and the construction efficiency.
