Description

Technical Field

[0001] This invention patent relates to the technical field of rubber waterstops, and more specifically, to a construction method for fixing a rubber waterstop for deformation joints. Background Art

[0002] Rubber waterstops are widely used in deformation joints, construction joints, and settlement joints of projects such as buildings, water conservancy, and tunnels to prevent water leakage. They mainly achieve the waterproof function by the elasticity and deformation ability of rubber to adapt to the expansion and contraction of the structure.

[0003] Currently, the construction methods for fixing rubber waterstops mainly include traditional fixing methods, fixing of externally bonded waterstops, and fixing of embedded waterstops. In actual applications, these methods have problems such as low construction efficiency and poor fixing stability of the waterstop.

[0004] In the prior art, the construction for fixing a rubber waterstop usually requires multiple steps, including the setting of positioning steel bars, clamping of the waterstop, installation and adjustment of formwork, etc. These steps not only consume time but also easily cause the displacement or damage of the waterstop due to improper operation. In addition, due to the complex and unstable fixing method, construction workers need to spend a lot of time on adjusting the waterstop and strengthening the formwork.

[0005] In addition, some fixing devices in the prior art need to be disassembled and installed multiple times, further reducing the construction efficiency. Summary of the Invention

[0006] The purpose of the present invention is to provide a construction method for fixing a rubber waterstop for deformation joints, aiming to solve the problem of low construction efficiency in fixing a rubber waterstop in the prior art.

[0007] The present invention is implemented as follows. The construction method for fixing a rubber waterstop for deformation joints includes the following construction steps:

[0008] 1). Arrange a rubber waterstop in the middle of the deformation joint. The rubber waterstop includes an elastic ring, and wing belts extend from both sides of the elastic ring. The elastic ring seals the middle of the deformation joint, and the wing belts extend into the pouring space; there is a steel bar frame in the pouring space, and the steel bar frame clamps and fixes the wing belts;

[0009] 2). The pouring space has a joint end facing the deformation joint. Two spaced-apart end formworks are covered at the joint end, and there is a formwork interval between the two end formworks. The elastic ring is embedded in the formwork interval;

[0010] 3) Between the two end templates, there is a tongue-and-groove wooden square. The two ends of the tongue-and-groove wooden square are respectively fixedly connected to the two end templates. The tongue-and-groove wooden square abuts against the elastic ring, closing the template intervals. The two end templates and the tongue-and-groove wooden square wrap and fix the elastic ring.

[0011] Further, in the construction step 3), after the tongue-and-groove wooden square is fixed, two spaced-apart middle wooden squares are connected to the outside of the tongue-and-groove wooden square. There is a clamping interval between the two middle wooden squares. The wing belt is clamped in the clamping interval. The middle wooden squares press against the end templates towards the pouring space.

[0012] Further, in the step 3), a plurality of side wooden squares are connected to the outer periphery of the end template. The plurality of side wooden squares press against the end template towards the pouring space.

[0013] Further, in the construction step 3), after the middle wooden squares and the side wooden squares are arranged, main wooden squares are arranged on the outer periphery of the end template. The main wooden squares respectively press against the middle wooden squares and the side wooden squares, so that the middle wooden squares press against the tongue-and-groove wooden square towards the pouring space, and the side wooden squares press against the end template towards the pouring space.

[0014] Further, in the construction step 3), after the main wooden squares are arranged, a reinforcement structure is arranged on the outside of the main wooden squares. The reinforcement structure presses against the main wooden squares towards the pouring space, so that the main wooden squares press against the middle wooden squares and the side wooden squares.

[0015] Further, in the construction step 3), the reinforcement structure includes a pressing steel pipe and two swinging steel pipes. After the pressing steel pipe presses against the main wooden square, the two swinging steel pipes are swung to both sides of the pouring space and fixedly arranged, so that the pressing steel pipe fixedly presses against the main wooden square towards the pouring space.

[0016] Further, in the construction step 1), the steel bar frame clamps and fixes the wing belt in a sheet shape.

[0017] Further, in the construction step 1), there are strip-shaped clamping grooves in the steel bar frame. After the wing belt extends into the pouring space, it is embedded in the clamping grooves in a sheet shape and clamped and fixed by the steel bar frame.

[0018] Further, in the construction step 1), clamping frames are respectively arranged on both sides of the clamping groove. One end of the clamping frame forms a fixed end that faces the elastic ring and is fixedly arranged. The other end of the clamping frame forms a free end that is freely arranged. The clamping groove is formed between the two clamping frames;

[0019] The clamping frame encloses a hollow square area, and an elastic bending strip is arranged in the square area, and the bending strip is arranged to be convex and curved away from the elastic ring; the upper end and the lower end of the bending strip are respectively fixedly connected to the clamping frame, and the middle part of the bending strip is connected to a rolling roller with a different shape, and the outer periphery of the rolling roller is convexly provided with a plurality of convex ribs with different heights, and the plurality of convex ribs are arranged at intervals along the circumference of the rolling roller;

[0020] In the construction step 1), the wing band is inserted into the clamping gap and clamped by the two clamping frames. When the steel frame is fixed in the casting space and the wing band is extended in sheet form, the rolling roller is rotated away from the elastic ring. The convex ribs on the rolling roller press the wing band away from the elastic ring to tension it until the wing band reaches the set tensioning degree.

[0021] Furthermore, in the construction step 1), a plurality of longitudinally arranged main steel bars are provided in the casting space. When the wing band extends into the casting space, the wing band is clamped and fixed by the steel bar frame, and then the steel bar frame is bent and arranged in multiple positions to form a plurality of bending positions. The plurality of main steel bars respectively pass through the plurality of bending positions and are fixedly connected to the steel bar frame, so that the steel bar frame is fixed in the casting space and the wing band is tensioned and fixed in sheet form.

[0022] Compared with the prior art, the deformation joint rubber water stop belt fixing construction method provided by the present invention has the following advantages:

[0023] 1) By arranging the rubber water stop in the middle of the deformation joint and clamping the wing belt with a steel frame, the fixing process of the water stop is simplified and the construction steps are reduced, thereby achieving efficient construction of the rubber water stop. This not only reduces the construction time, but also reduces the construction difficulty, allowing construction personnel to complete the fixing of the water stop more quickly and conveniently;

[0024] 2) An end formwork and a tongue-and-groove square timber are set at the end of the seam. The tongue-and-groove square timber abuts against the elastic ring and closes the template interval, and the elastic ring is wrapped and fixed together with the end formwork. This structural setting not only enhances the fixing effect of the waterstop, but also improves the stability of the waterstop during the pouring process, effectively preventing the displacement and deformation of the waterstop, thereby ensuring the sealing performance of the waterstop;

[0025] 3) By setting up spaced end formwork at the ends of the joints in the casting space, the elastic ring can be embedded in the formwork interval, so that the waterstop can better adapt to the expansion and contraction changes of the deformation joint, thereby improving the adaptability and reliability of the waterstop.

[0036] Refer to Figures 1-4 as shown, which is a preferred embodiment provided by the present invention.

[0037] The construction method for fixing the deformation joint rubber waterstop includes the following construction steps:

[0038] 1), Arrange a rubber waterstop in the middle of the deformation joint. The rubber waterstop includes an elastic ring, and wing belts extend from both sides of the elastic ring. The elastic ring seals the middle of the deformation joint, and the wing belts extend into the pouring space; there is a steel bar frame in the pouring space, and the steel bar frame clamps and fixes the wing belts;

[0039] 2), The pouring space has a joint end facing the deformation joint. Two end templates arranged at intervals are sealed at the joint end. There is a template interval between the two end templates, and the elastic ring is embedded in the template interval;

[0040] 3), A tongue-and-groove wooden square is provided between the two end templates. The two ends of the tongue-and-groove wooden square are respectively fixedly connected to the two end templates. The tongue-and-groove wooden square abuts against the elastic ring to seal the template interval, and the two end templates and the tongue-and-groove wooden square wrap and fix the elastic ring.

[0041] The above-provided construction method for fixing the rubber waterstop of the deformation joint has the following advantages:

[0042] 1), By arranging the rubber waterstop in the middle of the deformation joint and using the steel bar frame to clamp and fix the wing belts, the fixing process of the waterstop is simplified, the construction steps are reduced, thereby realizing the efficient construction of fixing the rubber waterstop. This not only reduces the construction time but also reduces the construction difficulty, enabling the construction personnel to complete the fixing work of the waterstop more quickly and conveniently;

[0043] 2), Set end templates and tongue-and-groove wooden squares at the joint end. The tongue-and-groove wooden square abuts against the elastic ring to seal the template interval and, together with the end templates, wraps and fixes the elastic ring. Through this structural setting, not only the fixing effect of the waterstop is enhanced, but also the stability of the waterstop during the pouring process is improved, effectively preventing the displacement and deformation of the waterstop, thereby ensuring the sealing performance of the waterstop;

[0044] 3), By setting end templates arranged at intervals at the joint end of the pouring space, the elastic ring can be embedded in the template interval, enabling the waterstop to better adapt to the expansion and contraction changes of the deformation joint, and improving the adaptability and reliability of the waterstop.

[0045] In this embodiment, in construction step 3), after the tongue-and-groove wooden square is fixed, two middle wooden squares arranged at intervals are connected to the outside of the tongue-and-groove wooden square. There is a clamping interval between the two middle wooden squares, and the wing belt is clamped in the clamping interval. The middle wooden squares press against the end templates towards the pouring space.

[0046] In this way, not only the fixing effect of the wing belt is enhanced, but also the stability of the overall structure is improved by the pressing of the middle wooden squares against the end templates. In addition, the setting of the middle wooden squares simplifies the construction process and reduces the dependence on other fixing measures, thereby improving the construction efficiency of fixing the rubber waterstop to a certain extent.

[0047] In this embodiment, in step 3), a plurality of side wooden beams are connected to the outer periphery of the end formwork, and the plurality of side wooden beams press against the end formwork towards the pouring space.

[0048] The side wooden beams effectively disperse the pressure on the end formwork, enhancing the stability of the formwork. At the same time, they also provide additional support for the keyway wooden beam and the middle wooden beam, contributing to improving the construction efficiency because it reduces the need for complex fixing devices, making the construction process more direct and efficient.

[0049] In this embodiment, in construction step 3), after arranging the middle wooden beam and the side wooden beams, main wooden beams are arranged on the outer periphery of the end formwork. The main wooden beams press against the middle wooden beam and the side wooden beams respectively, so that the middle wooden beam presses against the keyway wooden beam towards the pouring space, and the side wooden beams press against the end formwork towards the pouring space.

[0050] The main wooden beams form a more stable structural framework, not only enhancing the fixing effect of the middle wooden beam and the side wooden beams, but also further improving the stability of the entire waterstop fixing system through the pressing action.

[0051] In this embodiment, in construction step 3), after arranging the main wooden beams, a reinforcement structure is arranged outside the main wooden beams. The reinforcement structure presses against the main wooden beams towards the pouring space, so that the main wooden beams press against the middle wooden beam and the side wooden beams.

[0052] In this way, it can provide additional stability and support force for the entire reinforcement structure, ensuring the fixing effect of the waterstop during the pouring process and improving the reliability of the construction.

[0053] In this embodiment, in construction step 3), the reinforcement structure includes a pressing steel pipe and two swinging steel pipes. After the pressing steel pipe presses on the main wooden beam, the two swinging steel pipes are swung to both sides of the pouring space and fixedly arranged, so that the pressing steel pipe fixedly presses against the main wooden beam towards the pouring space.

[0054] Through the setting of the reinforcement structure, it can not only adapt to the shape change of the pouring space, but also provide a uniform pressure distribution, thus ensuring the fixing effect of the waterstop and improving the adaptability of the construction.

[0055] In this embodiment, in construction step 1), the steel bar frame clamps and fixes the wing belt in a sheet shape.

[0056] In this way, it can ensure the position stability of the wing belt during the pouring process. At the same time, it is also convenient for construction workers to operate. Through the fixing action of the steel bar frame, the wing belt can better adapt to the changes of the deformation joint, thereby improving the waterstop effect.

[0057] In this embodiment, in construction step 1), the steel bar frame has strip-shaped clamping grooves. After the wing belt extends into the pouring space, it is embedded in the clamping grooves in a sheet shape and is clamped and fixed by the steel bar frame.

[0058] In this way, the wing belt can be fixed more stably at the predetermined position, and at the same time, it is convenient for construction workers to install and adjust, improving the construction accuracy and efficiency.

[0059] In this embodiment, in construction step 1), both sides of the clamping groove are respectively provided with clamping frames. One end of the clamping frame forms a fixed end that faces the elastic ring and is fixedly arranged, and the other end of the clamping frame forms a freely arranged free end. The clamping groove is formed between the two clamping frames;

[0060] The clamping frames enclose a hollow square area. An elastic bending strip is arranged in the square area, and the bending strip bulges and bends away from the elastic ring; the upper end and the lower end of the bending strip are respectively fixedly connected to the clamping frames, and a rolling roller with a different shape is connected to the middle of the bending strip. A plurality of convex ribs with different heights are convexly arranged on the outer circumference of the rolling roller, and the plurality of convex ribs are arranged at intervals along the circumferential direction of the rolling roller;

[0061] In construction step 1), the wing belt is inserted into the clamping gap and is clamped by the two clamping frames in opposite directions. When the steel bar frame is fixed in the pouring space and the wing belt extends in a sheet shape, the rolling roller is rotated away from the elastic ring, and the convex ribs on the rolling roller press against the wing belt to be tensioned away from the elastic ring until the wing belt reaches the set tension degree.

[0062] Through the combined action of the rolling roller and the convex ribs, the precise control of the tension degree of the wing belt is realized, thus ensuring the sealing performance of the water stop belt. Such a fine adjustment method helps to improve the construction quality. At the same time, it also makes the construction process more controllable and efficient.

[0063] In this embodiment, in construction step 1), a plurality of longitudinally arranged main steel bars are provided in the pouring space. After the wing belt extends into the pouring space, after the wing belt is clamped and fixed by the steel bar frame, the steel bar frame is bent and arranged at multiple positions to form a plurality of bending positions. The plurality of main steel bars respectively pass through the plurality of bending positions and are fixedly connected to the steel bar frame so that the steel bar frame is fixed in the pouring space and the wing belt is tensioned and fixed in a sheet shape.

[0064] Through the combination of the main steel bars and the steel bar frame, a stable fixing structure is formed, which not only improves the fixing effect of the water stop belt, but also enables the steel bar frame to better adapt to the shape change of the pouring space through the multi-position bending arrangement, thereby improving the construction flexibility and efficiency.

[0065] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
