Description

Technical Field

[0001] This utility model relates to the field of tunnel reinforcement construction technology, specifically to a sealing structure for joints of prefabricated components. Background Technology

[0002] Waterproofing of structural components includes both the waterproofing of the structure itself and the waterproofing of the assembled components. Components are arranged to form a complete structure, and the waterproofing system of the assembled structure between adjacent components is crucial to the overall structure. It requires that the waterproofing materials adhere tightly to each other to achieve a good waterproofing effect, preventing leakage and seepage between structural components. The effectiveness of the waterproofing system directly affects the quality of the completed structure. Especially in tunnel reinforcement construction, the circumferential tightness between prefabricated components directly affects the quality of the reinforcement result. However, existing sealing and waterproofing structures typically rely on adhesives, which are often ineffective. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the prior art by providing a prefabricated component joint sealing structure. By setting an anti-slip structure on the top or bottom surface of the I-shaped main body, the friction between the sealing structure and the tunnel inner wall can be increased, thereby preventing circumferential displacement. The stainless steel wire embedded inside the I-shaped main body can enhance the deformation resistance and improve the structural strength of the joint. The groove opening of the insertion groove has a chamfer, which facilitates the insertion of prefabricated components and makes construction easier.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A precast component joint sealing structure includes an I-shaped main body, comprising a horizontally arranged top plate and bottom plate, and a vertical plate connecting the top plate and bottom plate.

[0019] The features and other related features of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art:

[0020] like Figure 1-3 As shown in the figure, the markings represent: top plate 1, bottom plate 2, vertical plate 3, insertion groove 4, anti-slip structure 5, stainless steel wire 6, chamfer 7, drainage hole 8, and groove 9.

[0021] Example: Figure 1-3As shown, this embodiment relates to a precast component joint sealing structure. This sealing structure is used for sealing the joints of precast components, and more specifically, for sealing and waterproofing between adjacent circumferential templates during tunnel reinforcement construction. The sealing structure in this embodiment includes an I-shaped main body, comprising a horizontally arranged top plate 1 and bottom plate 2, and a vertically connected vertical plate 3. The two sides of the vertical plate 3, together with the top plate 1 and bottom plate 2, form insertion grooves 4 for inserting the ends of precast components. The top plate 1, bottom plate 2, and vertical plate 3 together constitute an I-shape. Furthermore, the top plate 1 and... Alternatively, an anti-slip structure 5 may be provided on the surface of the bottom plate 2 facing away from the vertical plate 3. When using this sealing structure to seal the joint between the two templates, the two templates are respectively inserted into the insertion grooves 4 on both sides of the I-shaped main body. When the anti-slip structure 5 is provided on the surface of the top plate 1 or the bottom plate 2 facing away from the vertical plate 3, by adjusting the placement of the I-shaped main body, the surface facing the inner wall of the tunnel segment is the side with the anti-slip structure 5. That is, the anti-slip structure 5 can be used to increase the friction between the sealing structure and the inner wall of the tunnel segment, thereby preventing the template and the sealing structure from circumferentially displacing in the tunnel. Of course, when the anti-slip structure 5 is provided on the surface of both the top plate 1 and the bottom plate 2 facing away from the vertical plate 3, it is not necessary to distinguish the front and back of the sealing structure when inserting the templates, and it can always be ensured that the surface facing the inner wall of the tunnel segment has the anti-slip structure 5.

[0022] In this embodiment, stainless steel wires 6 are embedded inside the top plate 1, bottom plate 2, and vertical plate 3. By embedding stainless steel wires 6 inside the I-shaped main body, the resistance to deformation can be enhanced, and the structural strength at the joints can be improved. Optionally, the diameter of the stainless steel wires 6 can be in the range of 1–2 mm.

[0023] In this embodiment, further, a chamfer 7 is formed at the opening of the insertion groove 4 on both sides of the I-shaped main body. The chamfer 7 structure makes the size of the opening of the insertion groove 4 slightly larger than the size of other positions of the insertion groove 4, so as to play a guiding role in the process of inserting the template into the insertion groove 4, making it convenient for the template to be inserted into the insertion groove 4.

[0024] In some embodiments, the I-shaped main body is provided with a plurality of drainage holes 8, each drainage hole 8 having its two ends respectively located on the top plate 1 and the bottom plate 2, and the drainage holes 8 penetrating the vertical plate 3. The plurality of drainage holes 8 are spaced apart along the length of the I-shaped main body. Thus, when either the top plate 1 or the bottom plate 2 of the sealing structure is opposite to the inner wall of the tunnel segment, water between the sealing structure and the inner wall of the tunnel segment can be drained through the drainage holes 8. When the joint is not located in the top area of ​​the annular tunnel segment, water accumulated between the template and the tunnel segment can also flow circumferentially to the joint location and be drained through the drainage holes 8, thereby improving the quality of tunnel reinforcement construction.

[0025] Optionally, the inner wall of the insertion groove 4 is coated with adhesive, and the end of the prefabricated component is bonded to the I-shaped body with adhesive, thereby further improving the sealing effect between the two.

[0026] In other embodiments, a plurality of grooves 9 are provided on two opposing inner wall surfaces within the insertion groove 4, and the grooves 9 are spaced apart in the depth direction of the insertion groove 4. After the template is inserted into the insertion groove 4, the grooves 9 increase the friction between the template and the inner wall surface of the insertion groove 4. Furthermore, before inserting the template, adhesive is first applied to the inner wall of the insertion groove 4. The presence of the grooves 9 allows for a larger amount of adhesive to be stored in the insertion groove 4, resulting in a larger contact area. This makes the end of the prefabricated component more firmly bonded to the I-shaped body through adhesive, and improves the sealing performance.

[0027] In this embodiment, optionally, the anti-slip structure 5 is a plurality of spaced anti-slip protrusions, or the anti-slip structure 5 is a serrated texture. The processing method of anti-slip protrusions or serrated textures is simple, easy to form, and has a good effect of increasing frictional resistance.

[0028] In this embodiment, the main body of the I-shaped structure is made of silicone rubber. That is, the top plate 1, the bottom plate 2, and the vertical plate 3 are all made of silicone rubber, and the three can be integrally molded. Silicone rubber has the characteristics of high and low temperature resistance.

[0029] Optionally, the width of the insertion groove 4 is in the range of 8~15mm, which can better match the thickness of the template end; while the depth of the insertion groove 4 is in the range of 5~12mm, which can ensure the stability of the template after insertion.

[0030] In this embodiment, the chamfer 7 has an angle range of 45° to 60° to better guide the template during the template insertion process and reduce the difficulty of insertion.

[0031] Optionally, the thickness of the top plate 1 and / or the bottom plate 2 is 5~10mm, and the thickness of the vertical plate 3 is 3~8mm, to ensure that the sealing structure has a certain structural strength without being too thick and forming a protrusion.

[0032] In summary, the beneficial effects of this utility model are as follows: by setting an anti-slip structure on the top or bottom surface of the I-shaped main body, the friction between the sealing structure and the inner wall of the tunnel can be increased by the anti-slip structure, thereby avoiding circumferential displacement; by embedding stainless steel wire inside the I-shaped main body, the deformation resistance can be enhanced and the structural strength of the joint position can be improved; the groove opening of the insertion groove is chamfered, which can facilitate the insertion of prefabricated components and facilitate construction operations.
