Description

Technical Field

[0001] The utility model belongs to the technical field of water stop belt installation, and specifically relates to a fixing structure of an embedded rubber water stop belt. Background Art

[0002] During the construction of underground projects, construction joints / deformation joints are often set in the structure due to the need for process and control of structural cracks. This joint will become a weak point in the structure and there is a risk of water leakage. One of the most important measures to prevent water leakage at construction joints / deformation joints is to set up an embedded rubber waterstop, and the embedded rubber waterstop is required to be buried near the center line of the structure and be linearly straight. Due to construction process and material reasons, the embedded rubber waterstop will have defects such as linear bending, inaccurate buried depth, and uneven depth after installation, which will bring certain hidden dangers to the quality of the structure and cause leakage at the construction joint / deformation joint in the later structure.

[0020] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0021] like Figure 1As shown, the fixed structure of the embedded rubber waterstop includes a steel frame 1, the steel frame 1 includes fixed steel bars 2, the fixed steel bars 2 are fixedly connected to the middle of the steel frame 1, a construction joint 4 is provided between the ends of the fixed steel bars 2, the waterstop 3 is located in the middle of the construction joint 4, the middle part of the waterstop 3 separates the construction joint 4, and the waterstop 3 is provided between the fixed steel bars 2.

[0022] The steel bar skeleton 1 is welded from three steel bars and is processed in the back field in advance. Two fixed steel bars 2 are provided and arranged in parallel. The two fixed steel bars 2 are used to fix the ends of the waterstop 3. The waterstop 3 separates the construction joint 4 to form a barrier to water and realize the water-stopping function. The fixed steel bars 2 are used to install and fix the waterstop 3 so that it is in the accurate installation position. The fixing of the embedded rubber waterstop is completed in two steps. The first fixing uses the steel bar skeleton 1 and the construction joint / deformation joint end template 10; when the embedded rubber waterstop is fixed for the first time, the waterstop 3 exposed in the early stage structure of the underground project can be clamped to ensure that the pre-buried depth of the waterstop 3 is consistent. The second fixing of the waterstop 3 uses the steel bar skeleton 1.

[0023] like Figure 1 As shown, the steel skeleton 1 is symmetrically arranged about the construction joint 4, and the fixed steel bars 2 are arranged in pairs, and the fixed steel bars 2 are arranged in parallel. One steel skeleton 1 is provided with two fixed steel bars 2 arranged in parallel, and the two fixed steel bars 2 can fix one end of the water stop 3. The two ends of the water stop 3 can be fixed by two sets of steel skeletons 1. The spacing of the steel skeletons 1 is determined comprehensively according to factors such as the rigidity of the embedded rubber water stop and the steel skeleton 1 to ensure that the linearity of the water stop 3 is consistent. The middle part of the water stop 3 is a bent structure, and the middle part of the water stop 3 corresponds to the construction joint 4, so that the water stopping effect of the concrete on both sides of the construction joint 4 is consistent, and the waterproof effect is improved at the same time.

[0024] like Figure 1 and Figure 2 As shown, the top and bottom ends of the steel frame 1 are fixedly connected with structural steel bars 7, the structural steel bars 7 are arranged horizontally, and the steel frame 1 is arranged vertically. The structural steel bars 7 provide an installation position for the steel frame 1, and the top and bottom ends of the steel frame 1 are welded and fixed to the underground structural steel bars 7. After being fixed, the steel frame 1 is in a vertical state, thereby ensuring that the pre-buried depth of the water stop 3 meets the standard and the water stop effect is ensured.

[0025] like Figure 4 As shown, protrusions 5 are provided at both ends of the water stop 3, and the fixed steel bars 2 press the protrusions 5. The setting of the protrusions 5 can facilitate the installation and fixation of the water stop 3. The width of the protrusions 5 is greater than the spacing between the two fixed steel bars 2. The spacing between the fixed steel bars 2 is the thickness of the embedded rubber water stop minus 2mm, which is slightly smaller than the thickness of the end of the water stop 3, and can play the role of clamping and fixing the water stop 3.

[0026] like Figure 1 and Figure 3As shown, the fixed steel bar 2 is inclined and the water stop 3 is V-shaped. The inclination angle of the fixed steel bar 2 is determined according to the angle of the water stop bend. The inclined fixed steel bar 2 is used to make the fixed water stop 3 form a V-shape. When water leaks along the construction joint 4, since the water stop 3 is V-shaped, it is more difficult for water to pass through the water stop 3 from top to bottom, thereby achieving a better water stop effect.

[0027] like Figure 4 As shown, the end of the water stop 3 is provided with a steel edge 6. The steel edge 6 can not only extend the width and slow down the water seepage rate, but also has strong adhesion to the concrete, so that the water stop 3 can withstand greater tension and torsion, making it more difficult for the water stop 3 to loosen and fall off.

[0028] The ends of the steel bar skeleton 1 are welded to the structural steel bars 7, and the fixed steel bars 2 are welded to the steel bar skeleton 1. By welding, the above steel bars can be quickly connected into an integrated structure, which is fast and convenient to operate and ensures sufficient connection strength.

[0029] After the specifications, models and positions of the embedded rubber waterstop are determined according to the design drawings, the fixing of the embedded rubber waterstop is completed in two steps. Before the concrete of the underground structure of the first section is poured, the steel skeleton 1 is welded according to the specifications, models and positions of the embedded rubber waterstop, and the construction joint / deformation joint end template 10 is divided into two upper and lower parts at the position of the embedded waterstop 3, and the first fixing of the embedded rubber waterstop is completed in combination with the end template of the construction joint 4 / deformation joint. After the concrete of the underground structure of the first section is poured, the construction joint / deformation joint end template 10 is removed, and the steel skeleton 1 is used again to complete the second fixing of the embedded waterstop 3.

[0030] The construction method includes the following steps:

[0031] Step 1: Process the steel frame 1 according to the specification, model and bending angle of the embedded rubber waterstop.

[0032] Step 2: Make a construction joint / deformation joint end template 10, and divide it into two pieces at the position of the embedded rubber waterstop.

[0033] Step 3: Construction of the preliminary structure of the underground project, completion of the installation of steel bars and formwork, the initial fixation of the embedded rubber waterstop, and completion of concrete pouring.

[0034] Step 4: Remove the construction joint / deformation joint end formwork 10, install the structural reinforcement 7 and formwork of the later stage of the underground project, and fix the embedded rubber waterstop strip for the second time, and complete the concrete pouring.

[0035] The fixing structure of the embedded rubber waterstop ensures that the installed embedded rubber waterstop is linearly straight and accurately positioned by fixing the waterstop 3 with the steel frame 1, ensures that the pre-embedded depth of the waterstop 3 is consistent, simplifies the operation process, and the fixing method is simple and convenient; by tilting the fixing steel bars 2, the waterstop 3 forms a V-shaped structure, which improves the water-stopping effect and ensures the waterproof construction quality of the construction joint 4 / deformation joint. The steel structure is used to fix the waterstop 3, and the fixing effect with the concrete is firm and reliable, the fixing stability is high, and the structure is simple and the application cost is low.

[0036] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
