Description

Technical Field

[0001] This utility model relates to the field of building technology, and in particular to a leak-stopping structure. Background Technology

[0002] Concrete is made by mixing water, cement, and sand in a certain proportion, followed by stirring, molding, and curing. During the pouring of concrete, water and cement may seep out from the joints, resulting in grout leakage.

[0003] This can lead to a decrease in the uniformity, density, and integrity of the concrete, which in turn reduces the strength of the components and affects the quality and safety of the building. Utility Model Content

[0004] The purpose of this invention is to provide a leak-stopping structure to improve the strength of components and ensure the quality and safety of buildings.

[0005] To achieve the above objectives, this utility model provides a leak-sealing structure. The leak-sealing structure includes a first body, a second body, and a telescopic connecting assembly. The second body is positioned opposite and spaced apart from the first body. The telescopic connecting assembly has two opposing ends, which are respectively connected to the first body and the second body. The telescopic connecting assembly drives the first body and the second body to move closer together or further apart.

[0006] The following analysis uses a component as an example. The component includes at least two adjacent templates with a gap between them. In actual use, the inner surfaces of both the first and second bodies simultaneously abut against the sidewalls of the two adjacent templates. The expansion joint is located within the gap between the two adjacent templates, and its sidewall abuts against the sidewalls of the two templates facing the gap. At this point, the sealing structure seals the gap between the two adjacent templates, reducing or eliminating the probability of concrete seeping out from the gap during concrete pouring, thus reducing or eliminating the probability of grout leakage. Based on this, the strength of the component composed of templates can be improved, thereby ensuring the quality and safety of the structure formed after pouring. Furthermore, since grout leakage is reduced or eliminated, concrete waste can be reduced, saving construction costs. Moreover, after construction is completed, the sealing structure can be disassembled for later reuse, further reducing costs. Furthermore, since the telescopic connecting assembly can move the first and second bodies closer together or further apart, the leak-sealing structure provided by this invention can be applied to gaps of different lengths (in other words, to templates of different widths), thus expanding the applicability of the leak-sealing structure. It should be noted that the dimensions of the aforementioned telescopic connecting assembly can be set according to the dimensions of the gap to be sealed, ensuring that the sidewalls of the telescopic connecting assembly abut against the sidewalls of the two templates respectively, sealing the gap between adjacent templates.

Detailed Implementation

[0059] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0060] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0061] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0062] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0063] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0064] To address the aforementioned technical problems, this utility model provides a leak-sealing structure. See also... Figures 1 to 3The leak-sealing structure 1 includes a first body 10, a second body 11, and a telescopic connecting assembly 12. The second body 11 is opposite to and spaced apart from the first body 10. The telescopic connecting assembly 12 has two opposite ends, which are respectively connected to the first body 10 and the second body 11. The telescopic connecting assembly 12 drives the first body 10 and the second body 11 to move closer or further apart.

[0065] See Figures 1 to 9 The following analysis uses a component as an example. The component includes at least two adjacent templates with a gap between them. In actual use, the inner surfaces of the first body 10 and the second body 11 simultaneously abut against the sidewalls of the two adjacent templates. The expansion joint 12 is located within the gap between the two adjacent templates, and its sidewalls abut against the sidewalls of the two templates facing the gap. At this time, the sealing structure 1 seals the gap between the two adjacent templates, reducing or eliminating the probability of concrete seeping out from the gap during concrete pouring, thereby reducing or eliminating the probability of grout leakage. Based on this, the strength of the component composed of templates can be improved, thus ensuring the quality and safety of the building formed after pouring. Furthermore, since grout leakage is reduced or eliminated, concrete waste can be reduced, saving construction costs. Moreover, after construction is completed, the sealing structure 1 can be disassembled for later reuse, further reducing costs. Furthermore, since the telescopic connecting component 12 can move the first body 10 and the second body 11 closer together or further apart, the leak-sealing structure 1 provided in this embodiment can be applied to gaps of different lengths (in other words, to templates of different widths), thus expanding the applicability of the leak-sealing structure 1. It should be noted that the dimensions of the telescopic connecting component 12 can be set according to the dimensions of the gap to be sealed, ensuring that the sidewalls of the telescopic connecting component 12 abut against the sidewalls of the two templates respectively, sealing the gap between adjacent templates.

[0066] As one possible implementation, see Figures 1 to 19 The aforementioned telescopic connecting assembly 12 includes a first connecting unit 120 and a second connecting unit 121. The connection method between the first connecting unit 120 (or the second connecting unit 121) and the first body 10 (or the second body 11) can be configured according to actual conditions. For example, the first connecting unit 120 (or the second connecting unit 121) is fixedly connected to the first body 10 (or the second body 11), for example, by welding, bonding, etc. Alternatively, one end of the first connecting unit 120 is detachably connected to the first body 10, and one end of the second connecting unit 121 is detachably connected to the second body 11. When the two structures are detachably connected, it facilitates the storage and carrying of the leak-sealing structure 1. The first connecting unit 120 and the second connecting unit 121 are guided together to move the first body 10 and the second body 11 closer together or further apart.

[0067] In one alternative approach, see Figure 1 , Figures 4 to 6 The first body 10 has a first groove 100, and the second body 11 has a second groove 116. For example, the first groove 100 is formed at the middle position of the first body 10 along the height direction H1, and the extension direction of the first groove 100 is consistent with the width direction W1 of the first body 10. The second groove 116 is formed at the middle position of the second body 11 along the height direction H2, and the extension direction of the second groove 116 is consistent with the width direction W2 of the second body 11. It should be noted that the first groove 100 and the second groove 116 are positioned opposite each other to facilitate the guiding connection of the first connecting unit 120 and the second connecting unit 121.

[0068] See Figure 1 , Figure 2 and Figure 4 The first connecting unit 120 includes a base 1200 and a first guide structure 1201. One end of the base 1200 is guided and connected to the first groove 100, and the first guide structure 1201 is disposed on the base 1200. For example, one end of the base 1200 is a guide rail slider that matches the first groove 100. In this case, one end of the base 1200 can be pushed into the first groove 100 from the opening of the first groove 100 and inserted into the first body 10, thereby realizing a tight connection between the base 1200 and the first body 10.

[0069] See Figure 1 and Figure 6 The second connecting unit 121 includes a carrier member 1210. One end of the carrier member 1210 is guided and connected to the second groove 116. The carrier member 1210 has a second guide structure 1211, and the carrier member 1210 is guided and connected to the first guide structure 1201 through the second guide structure 1211.

[0070] For example, see Figure 1 and Figure 6 One end of the support member 1210 is a guide rail slider that matches the second groove 116. At this time, one end of the support member 1210 can be pushed into the second groove 116 from the opening of the second groove 116 and inserted into the second body 11, thereby realizing the fast connection between the support member 1210 and the second body 11.

[0071] It should be noted that the opening of the first groove 100 should engage with the upper or lower surface of the base 1200, and the opening of the second groove 116 should engage with the upper or lower surface of the carrier 1210 to prevent the telescopic connection assembly 12 from falling off.

[0072] See Figure 1 and Figure 2 The first guide structure 1201 can be a slide groove, and the second guide structure 1211 can be a guide rail slide that matches the slide groove. Alternatively, the first guide structure 1201 can be a guide rail slide, and the second guide structure 1211 can be a slide groove that matches the guide rail slide.

[0073] In this embodiment of the invention, the base is provided with two parallel guide rails, and the bearing member has two parallel sliding grooves. The length directions of the guide rails and the sliding grooves are consistent with the direction from the first body to the second body. The cross-sectional dimensions of the guide rails are 5mm × 5mm, and the length can be set according to actual conditions; the cross-sectional dimensions of the sliding grooves are 5mm × 5mm, and the length can be set according to actual conditions.

[0074] As one possible implementation, see Figure 3 The thickness D1 of the first body 10 is greater than the thickness D2 of the second body 11.

[0075] See Figure 3 and Figure 9 In practical use, the second body 11 is close to the later-poured concrete, while the first body 10 is located on the outside of the component, away from the later-poured concrete. Therefore, when the thickness of the first body 10 is greater than the thickness of the second body 11, it not only reduces the impact of the second body 11 on the volume of the later-poured concrete, ensuring that the quality of the building meets the actual requirements, but also ensures that the first body 10 can be stably fixed on the horizontal plane when the later component is a wall column 2.

[0076] In some embodiments, the thickness of the first body is 10 mm, and the thickness of the second body is less than or equal to 5 mm.

[0077] The surface of the first body that abuts against the template included in the component is rectangular, and the surface of the second body that abuts against the template included in the component is rectangular, to ensure that both the first body and the second body are fully abutted and fitted against the component.

[0078] The first and second ontology are described below using two different structures as examples. It should be noted that the following descriptions are for understanding purposes only and are not intended to limit specific aspects.

[0079] First type: See Figure 1Along the height direction H2 of the second body 11, the second body 11 includes a first surface 110 and a second surface 111 facing each other; the height direction H2 of the second body 11 is perpendicular to the direction A from the first body 10 to the second body 11; a plane located between the first body 10 and the second body 11 and perpendicular to the direction from the first body 10 to the second body 11 is defined as a first reference surface; the first reference surface has a first included angle B with the first surface 110 and / or the second surface 111; the first included angle B is an acute angle. That is, it may be only the first reference surface and the first surface 110 that have the first included angle B; or, only the first reference surface and the second surface 111 that have the first included angle B; or, the first reference surface and the first surface 110 have the first included angle B, and the first reference surface and the second surface 111 also have the first included angle B.

[0080] At this point, the first and / or second surfaces are inclined relative to the first reference surface, and the direction of the inclination is basically consistent with the direction of concrete falling. When pouring concrete, the concrete can fall along the inclined surface, reducing or eliminating the probability of concrete remaining on the leak-sealing structure.

[0081] In some embodiments, the first included angle B is greater than or equal to 30° and less than 90°. For example, the first included angle B can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, or 89°, etc.

[0082] In this embodiment of the invention, the side of the second body 11 with the second groove 116 (i.e., the side that abuts against the template included in the component) is perpendicular to the direction from the first body 10 to the second body 11, and this side faces the first body 10. To facilitate the identification of the first included angle B, the side of the second body 11 with the second groove 116 is used as the first reference surface. Figure 6 As shown, the first included angle B is greater than or equal to 30° and less than 90°.

[0083] The structure of the first entity is not specifically limited here, as long as it meets the actual needs. For example, the first entity is a cuboid structure.

[0084] See Figures 1 to 9When the application scenario is wall column 2 (the component mentioned above is wall column 2), wall column 2 includes at least two wall column templates 20 arranged adjacent to each other along the height direction of wall column 2, with a gap between the two adjacent wall column templates 20. It should be noted that the leak-stopping structure 1 in the first case is not only applicable to wall column 2, but also to other vertical components. Here, only wall column 2 is used as an example for explanation. In actual use, one end of the base 1200 is pushed into the first groove 100 from the opening of the first groove 100 and inserted into the first body 10 to achieve a tight connection between the base 1200 and the first body 10. One end of the bearing member 1210 is pushed into the second groove 116 from the opening of the second groove 116 and inserted into the second body 11 to achieve a tight connection between the bearing member 1210 and the second body 11. Next, the first guide structure 1201 and the second guide structure 1211 are guided and connected, and the side of the first body 10 with the first groove 100 abuts against the side wall of the wall column formwork 20 away from the later-poured concrete, and the side of the second body 11 with the second groove 116 abuts against the side wall of the wall column formwork 20 near the later-poured concrete. The first surface 110 of the second body 11 is away from the horizontal plane, and there is a first angle B between the first surface 110 and the first reference plane, which is 30°. The second surface 111 of the second body 11 is parallel to the horizontal plane, that is, the angle between the second surface 111 of the second body 11 and the first reference plane is 90°. At this time, it can be ensured that the second body 11 can be stably fixed on the horizontal plane.

[0085] Note that, see Figures 10 to 12 In the first scenario described above, construction joints will also occur between vertical components (e.g., wall column 2) and the plane (including bottom surface 6 and top surface 7), as well as at corners (e.g., corners of shear wall 3). Therefore, when constructing the corners of wall column 2 and shear wall 3, L-shaped sealing strips 5 are needed to seal these construction joints. For example, the L-shaped sealing strip 5 includes a first part 50 and a second part 51 connected together. When sealing the construction joint between wall column 2 and the plane, the second part 51 extends into the construction joint, and adhesive is applied to the position where the first part 50 contacts the surface of wall column 2 to prevent displacement of the sealing strip. It should be noted that the L-shaped sealing strip 5 is located on the side of wall column 2 away from the later-poured concrete. When sealing the construction joint at the corner of shear wall 3, adhesive is applied to the positions of the L-shaped sealing strip 5 that need to contact the corner of shear wall 3 to ensure a firm bond between the L-shaped sealing strip 5 and shear wall 3. It should be noted that the L-shaped sealing strip 5 is located on the side of the shear wall 3 away from the later-poured concrete. In some embodiments, the thickness of the first portion 50 of the L-shaped sealing strip 5 is 5 mm, and the thickness of the second portion 51 is set according to the size of the construction joint, as long as it is ensured that the second portion 51 can seal the construction joint.

[0086] The second option: See also Figures 13 to 19 Along the circumference of the second body 11, the second body 11 sequentially includes a first side surface 112, a second side surface, a third side surface 113, and a fourth side surface. The first side surface 112 and the third side surface 113 are arranged opposite to each other, and the second side surface and the fourth side surface are arranged opposite to each other. The first side surface 112 is connected to the telescopic connecting assembly 12. Along the length direction L2 of the second body 11, the third side surface 113 includes a first sub-side surface 114 and a second sub-side surface 115. The length direction L2 of the second body 11 is perpendicular to the direction A from the first body 10 to the second body 11. A plane located between the first body 10 and the second body 11 and perpendicular to the direction from the first body 10 to the second body 11 is defined as a first reference surface. There is a second included angle C between the first reference surface and the first sub-side surface 114. There is a third included angle D between the first reference surface and the second sub-side surface 115. Both the second included angle C and the third included angle D are acute angles.

[0087] At this time, the first sub-side 114 and the second sub-side 115 are inclined planes relative to the first reference plane, and the direction of inclination is basically consistent with the direction of concrete falling. When pouring concrete, the concrete can fall along the inclined plane, reducing or eliminating the probability of concrete remaining on the leak-sealing structure 1.

[0088] In some embodiments, see Figure 13 The included angles C and D can be equal or unequal. In this embodiment of the invention, the included angle C is equal to the included angle D, and the included angle C is less than or equal to 15°. For example, the included angle C can be 15°, 13°, 10°, 8°, 7°, 6°, 5°, 4°, or 3°, etc.

[0089] As one possible implementation, see Figure 13 Along the circumference of the first body 10, the first body 10 sequentially includes a fifth side surface 101, a sixth side surface, a seventh side surface 102, and an eighth side surface. The fifth side surface 101 and the seventh side surface 102 are arranged opposite each other, as are the sixth side surface and the eighth side surface. The fifth side surface 101 is connected to the telescopic connecting assembly 12. Along the length direction L1 of the first body 10, the seventh side surface 102 includes a third sub-side surface 103 and a fourth sub-side surface 104. The length direction L1 of the first body 10 is perpendicular to the direction A from the first body 10 to the second body 11. A plane located between the first body 10 and the second body 11 and perpendicular to the direction from the first body 10 to the second body 11 is defined as the second reference surface. There is a fourth included angle E between the second reference surface and the third sub-side surface 103. There is a fifth included angle F between the second reference surface and the fourth sub-side surface 104. Both the fourth included angle E and the fifth included angle F are acute angles. At this time, both the third sub-side surface 103 and the fourth sub-side surface 104 are inclined surfaces relative to the second reference surface.

[0090] In some embodiments, see Figure 13 The included angles E and F can be equal or unequal. In this embodiment of the invention, the included angle E is equal to the included angle F, and the included angle E is greater than or equal to 15° and less than or equal to 30°. For example, the included angle E can be 15°, 18°, 20°, 22°, 25°, 27°, 29°, or 30°, etc.

[0091] See Figures 13 to 19 When the application scenario is a beam-slab 4 (the component mentioned above is a beam-slab 4), the beam-slab 4 includes at least two beam-slab templates 40 arranged adjacent to each other along the length direction of the beam-slab 4, with a gap between the two adjacent beam-slab templates 40. It should be noted that the leak-stopping structure 1 in the second case is not only applicable to beam-slab 4, but also to other horizontal components. Here, only the beam-slab 4 is used as an example for explanation. In actual use, one end of the base 1200 is pushed into the first groove 100 from the opening of the first groove 100 and inserted into the first body 10 to achieve a tight connection between the base 1200 and the first body 10. One end of the bearing member 1210 is pushed into the second groove 116 from the opening of the second groove 116 and inserted into the second body 11 to achieve a tight connection between the bearing member 1210 and the second body 11. Next, the first guide structure 1201 and the second guide structure 1211 are guided and connected, and the side of the first body 10 with the first groove 100 abuts against the side wall of the beam and slab formwork 40 away from the later-poured concrete, and the side of the second body 11 with the second groove 116 abuts against the side wall of the beam and slab formwork 40 near the later-poured concrete. Further, since the first body 10 is below the second body 11, to prevent the first body 10 from falling off the beam and slab formwork 40 under gravity, adhesive is applied to the side of the first body 10 with the first groove 100 to prevent the sealing structure 1 from falling off. Further still, a second included angle C is formed between the first reference surface and the first sub-side surface 114, and a third included angle D is formed between the first reference surface and the second sub-side surface 115. The second included angle C is equal to the third included angle D, and both the second included angle C and the third included angle D are 10°. There is a fourth included angle E between the second reference plane and the third sub-side plane 103, and a fifth included angle F between the second reference plane and the fourth sub-side plane 104. The fourth included angle E is equal to the fifth included angle F, and both the fourth included angle E and the fifth included angle F are 15°.

[0092] As one possible approach, the material of the sealing structure can be selected based on the specific circumstances, such as PVC (Polyvinyl chloride). PVC material has advantages such as high ductility, good impact resistance, wear resistance, cut resistance, good chemical resistance, and low production cost. Therefore, sealing structures made of PVC material also offer these advantages, not only better sealing gaps and preventing concrete leakage, but also facilitating the reuse of the sealing structure and reducing construction costs. It should be noted that when the sealing structure is made of PVC, the material loses its toughness when heated. Therefore, during construction, the PVC sealing structure should be protected from open flames or other high-temperature environments to prevent it from losing its toughness and becoming unable to withstand the lateral pressure of the concrete, thus causing damage. Secondly, since PVC is a non-degradable plastic, it has a certain impact on the environment. Therefore, after construction, the PVC sealing structure should be disposed of in a centralized and reasonable manner to prevent environmental pollution.

[0093] As one possible implementation, see Figure 3 , Figure 4 , Figures 20 to 22 The first body 10 and the second body 11 have connecting holes 13 at their ends, and adjacent sealing structures 1 are connected by connectors 8 and connecting holes 13. For example, the connector 8 can be a bolt. Along the length of the template, the two ends of the bolt are respectively connected to the connecting holes 13 of the first body 10 included in the first sealing structure 1 and the connecting holes 13 of the second body 11 included in the second sealing structure 1. It should be noted that... Figure 20 and Figure 21 Only the first body 10 of the first sealing structure 1 and the second body 11 of the second sealing structure 1 are shown to aid in understanding the connection between two adjacent sealing structures 1. The material of the bolts can be selected according to the actual situation, for example, it can be PVC (Polyvinyl chloride). In this case, the sealing structure 1 and the connector 8 applied between the components are made of the same material, which facilitates construction.

[0094] Based on the preceding description, see [link / reference]. Figure 10 and Figure 23 The first portion 50 of the L-shaped sealing strip 5 also has a connecting hole 13 at its end. Adjacent L-shaped sealing strips 5 are connected by a connector 8 and the connecting hole 13. The connector 8 is also a bolt. For example, along the length of the template, the two ends of the bolt are respectively connected to the connecting hole 13 of the first portion 50 of the first L-shaped sealing strip 5 and the connecting hole 13 of the first portion 50 of the second L-shaped sealing strip 5. It should be noted that... Figure 20 , Figure 21 and Figure 23The connector 8 shown is a schematic diagram for illustrative purposes. For the specific structure of connector 8, please refer to [link / reference needed]. Figure 22 .

[0095] Based on the preceding description, once the concrete strength reaches the design requirements, the formwork and leak-sealing structure can be removed (if L-shaped leak-sealing strips are present, they must also be removed). During removal, if the leak-sealing structure is connected to the formwork, the connections between the leak-sealing structure and the formwork, and the bottom or top surface, should be removed first. Then, the leak-sealing structure should be removed, taking care not to damage the formwork or the leak-sealing structure during removal. After removal, it should be cleaned and stored promptly for future use.
