Description

Technical Field

[0001] The utility model belongs to the technical field of waterstops, and particularly relates to a pressure-resistant and deformation-resistant embedded waterstop. Background Art

[0002] Waterstop is made of natural rubber and various synthetic rubber as the main raw materials, mixed with various additives and fillers, and molded by plasticization, mixing, and pressing. There are many varieties and specifications, including bridge type, mountain type, P type, R type, U type, Z type, B type, T type, H type, E type, Q type, etc. The buried waterstop is a waterstop product mainly used for concrete deformation joints, expansion joints, etc. It has the ability to adapt to the expansion and contraction of concrete with the elasticity and structural form of rubber materials. It can be used in the field of underground car station construction to ensure the waterproof quality of subway stations and avoid water leakage at construction joints.

[0003] A Chinese patent with publication number CN206971287U discloses an embedded waterstop, including a base, at least two waterstop strips are fixed on the left and right sides of the base, at least one reinforcing rib is fixed to the interior or upper surface and / or lower surface of the base, the length direction of the reinforcing rib is perpendicular to the length direction of the waterstop strip, the height of the reinforcing rib is not greater than the height of the waterstop strip, the reinforcing rib is arranged in the form of blocks, strips or a mesh, and the reinforcing rib is integrated with the base.

[0004] During the use of traditional embedded waterstop, a round hole is often provided in the middle of the waterstop, with several protruding ridges or waterproof lines on both sides of the hole. This design can increase the contact area and friction between the waterstop and the concrete, and improve its ability to resist deformation. In order to further improve the compressive strength of the waterstop, steel-edge waterstops have gradually appeared on the market. Not only can the waterstop maintain better stability and shape integrity when subjected to high water pressure or external force, but this type of waterstop still has some shortcomings in actual use. For example, during the production process, a groove is usually opened on the rubber side of the waterstop, and then the steel belt is directly glued to this groove with glue. This traditional connection method has low strength and is prone to cause the steel belt and the edge of the waterstop to disengage in some parts during the construction process. Utility Model Content

[0005] In view of the problems mentioned in the background technology, the purpose of the present utility model is to provide a pressure-resistant and deformation-resistant embedded waterstop to solve the problems mentioned in the background technology.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] An embedded waterstop strip with compression resistance and anti-deformation, comprising a waterstop strip matrix. A waterstop bar is fixedly connected to the outside of the waterstop strip matrix. Through holes are provided inside the waterstop strip matrix.

[0008] The connecting mechanism includes connecting heads symmetrically arranged on the left and right sides of the waterstop strip matrix. Connecting grooves are provided on the outside of the connecting heads. The connecting steel strip is bonded inside the connecting grooves. The upper half of the inner wall of the connecting groove is provided with a first semi-circular groove, and the lower half of the inner wall of the connecting groove is fixedly connected with a first semi-circular protrusion. A second semi-circular protrusion is provided at the upper end of the connecting steel strip, and a second semi-circular groove is provided at the lower end of the connecting steel strip. The first semi-circular groove is adapted to the second semi-circular protrusion, and the second semi-circular groove is adapted to the first semi-circular protrusion. Through the connecting mechanism, the connection strength between the connecting steel strip and the waterstop strip matrix can be greatly improved;

[0009] The reinforcing fiber layer is woven from reinforcing warp threads and reinforcing weft threads. A fusion gap is provided between the reinforcing warp threads and the reinforcing weft threads. Through the reinforcing fiber layer inside the waterstop strip matrix, the structural strength and stability of the waterstop strip can be improved, and at the same time, its good flexibility can be maintained.

[0010] As a preferred technical solution, the number of the first semi-circular protrusions and the first semi-circular grooves is five each, and the cross-sectional shape of the connecting head is an isosceles trapezoid. Through the number of the first semi-circular protrusions and the first semi-circular grooves being five each, the connection between the connecting steel strip and the connecting groove can be made more compact.

[0011] As a preferred technical solution, V-shaped grooves are equidistantly provided on the upper and lower surfaces of the connecting steel strip, and riveting holes are symmetrically provided inside the connecting steel strip. Through the V-shaped grooves on the connecting steel strip, the bonding force between the waterstop strip and the concrete base surface can be improved.

The cross-section of the waterstop groove is V-shaped. Through the waterstop grooves, the waterstop effect of the waterstop bar can be further improved.

[0013] As a preferred technical solution, the nano-composite layer is specifically composed of nano-silica material, and the thickness of the nano-composite layer is 8um. By compounding the nano-composite layer composed of nano-silica on the outside of the waterstop strip matrix, the self-repairing ability of the waterstop strip matrix and the waterstop bar can be improved.

[0014] As a preferred technical solution, both the reinforcing warp and the reinforcing weft are formed by twisting 3 strands of carbon fiber wire bundles and 2 strands of glass fiber wire bundles. By using carbon fiber wire bundles and glass fiber wire bundles to form the reinforcing warp or the reinforcing weft, the tensile strength of the water stop belt substrate can be enhanced.

[0015] In summary, the present utility model mainly has the following beneficial effects:

[0016] First, by adding connecting heads at two places on the water stop belt substrate, the connecting heads are glued to the second semi-circular protrusion and the second semi-circular groove on the connecting steel belt through the first semi-circular groove and the first semi-circular protrusion in the connecting groove, which can expand the contact surface between the connecting steel belt and the connecting groove and make it more stable after gluing. And during the construction process, when one side of the connecting steel belt is stressed, part of the stress can be borne by the first semi-circular groove and the first semi-circular protrusion. Therefore, it is not easy to have the problem of the connecting steel belt and the water stop belt substrate being disengaged.

[0017] Second, by using the nano-composite layer composed of nano-silica particles to combine with the water stop belt substrate externally, not only the performance of the water stop belt substrate material is enhanced, but also the self-repairing ability of the water stop belt is indirectly improved. In addition, by using the reinforcing fiber layer woven by the reinforcing warp and the reinforcing weft, the tensile ability of the water stop belt can be greatly improved.

Detailed implementation mode

[0024] Reference Figures 1 to 5 , a middle-buried waterstop with compressive resistance and anti-deformation described in this embodiment includes a waterstop matrix 1. A waterstop strip 4 is fixedly connected to the outside of the waterstop matrix 1. A through hole 3 is provided inside the waterstop matrix 1. Connecting mechanisms 6 are provided on both the left and right sides of the waterstop matrix 1. The waterstop matrix 1 is bonded with a connecting steel strip 2 through the connecting mechanism 6. A nano-composite layer 9 is provided on the outside of the waterstop matrix 1, and a reinforcing fiber layer 10 is provided inside the waterstop matrix 1. By adopting the nano-composite layer 9 composed of nano-silica particles to combine with the waterstop matrix 1 on the outside, it not only enhances the performance of the waterstop matrix 1 material but also indirectly improves the self-healing ability of the waterstop; the nano-composite layer 9 is specifically composed of nano-silica material, and the thickness of the nano-composite layer 9 is 8um. The nano-silica coating usually has a rough structure at the micro-nano scale, and these structures are crucial for the superhydrophobic performance of the coating. When the coating is damaged, the nano-particles inside the coating can re-form a rough structure through migration and self-assembly, thereby restoring the superhydrophobic performance of the coating; the reinforcing fiber layer 10 is woven by reinforcing warp threads 101 and reinforcing weft threads 102. There is a fusion gap 1031 between the reinforcing warp threads 101 and the reinforcing weft threads 102. In addition, by adopting the reinforcing fiber layer 10 woven by the reinforcing warp threads 101 and the reinforcing weft threads 102, the tensile strength of the waterstop can be greatly improved. Among them, the fusion gap between the reinforcing warp threads 101 and the reinforcing weft threads 102 facilitates fusion in the waterstop matrix 1; currently, for the steel-edge middle-buried rubber waterstop on the market, the basic structure can already achieve the effects of compressive resistance and anti-deformation. Under the improvement effect of this technical solution, the use effect of this type of waterstop on the market can be greatly improved and enhanced;

[0025] The connecting mechanism 6 includes connecting heads 601 which are symmetrically arranged on the left and right sides of the waterstop matrix 1. A connecting groove 602 is formed on the outer side of the connecting head 601. The connecting steel strip 2 is bonded to the inner side of the connecting groove 602. On the upper half of the inner wall of the connecting groove 602, a first semi-circular groove 603 is formed. On the lower half of the inner wall of the connecting groove 602, a first semi-circular protrusion 604 is fixedly connected. On the upper end of the connecting steel strip 2, a second semi-circular protrusion 606 is provided. On the lower end of the connecting steel strip 2, a second semi-circular groove 605 is formed. The first semi-circular groove 603 and the second semi-circular protrusion 606 are adapted to each other, and the second semi-circular groove 605 and the first semi-circular protrusion 604 are adapted to each other. By adding connecting heads 601 at two places on the waterstop matrix 1, the first semi-circular groove 603 and the first semi-circular protrusion 604 in the connecting groove 602 of the connecting head 601 are glued to the second semi-circular protrusion 606 and the second semi-circular groove 605 on the connecting steel strip 2, which can expand the contact surface between the connecting steel strip 2 and the connecting groove 602 and make it more stable after gluing. And during the construction process, when one side of the connecting steel strip 2 is stressed, part of the stress can be borne by the first semi-circular groove 603 and the first semi-circular protrusion 604. Therefore, it is not easy to have the problem of the connecting steel strip 2 and the waterstop matrix 1 becoming disengaged.

[0026] Reference Figure 2 , both the number of the first semi-circular protrusions 604 and the first semi-circular grooves 603 is five. The cross-sectional shape of the connecting head 601 is an isosceles trapezoid. In the design, setting the number of the first semi-circular protrusions 604 and the number of the first semi-circular grooves 603 to be corresponding can facilitate a more compact connection between the connecting steel strip 2 and the connecting groove 602.

[0027] Reference Figure 2 , V-shaped grooves 8 are equidistantly formed on the upper and lower surfaces of the connecting steel strip 2. Riveting holes 7 are symmetrically formed on the inner side of the connecting steel strip 2. By using the V-shaped grooves 8 on the connecting steel strip 2, the bonding force between the waterstop and the concrete base surface can be improved, so that the waterstop is more firmly fixed in the reserved groove, reducing the leakage risk caused by reasons such as displacement and falling off. And the riveting holes 7 can facilitate the fixation of the connecting steel strip 2 parts of the two waterstop matrices 1 by using a fixing plate and matching rivets when connecting the waterstop matrices 1.

[0028] Reference Figure 1 , the cross-sectional shape of the waterstop strip 4 is a trapezoid. On the side of the waterstop strip 4 away from the waterstop matrix 1, waterstop grooves 5 are equidistantly formed. The cross-section of the waterstop groove 5 is V-shaped. By using the V-shaped waterstop grooves 5 on the waterstop strip 4, the waterstop effect of the waterstop strip 4 can be further improved.

[0029] Reference Figure 5, both the reinforcing warp 101 and the reinforcing weft 102 are formed by twisting 3 strands of carbon fiber wire bundles 1011 and 2 strands of glass fiber wire bundles 1012. The reinforcing warp 101 or the reinforcing weft 102 formed by twisting 3 strands of carbon fiber wire bundles 1011 and 2 strands of glass fiber wire bundles 1012 can significantly improve the structural strength and stability of the waterstop, while maintaining its good flexibility. When subjected to external forces, the fiber layer can disperse stress and prevent the waterstop from breaking or being damaged.

[0030] Principle of use and advantages: During use, the nano-composite layer 9 composed of nano-silica particles is used to combine it with the waterstop matrix 1 externally, which not only enhances the performance of the waterstop matrix 1 material, but also indirectly improves the self-healing ability of the waterstop. In addition, by using the reinforcing fiber layer 10 woven from the reinforcing warp 101 and the reinforcing weft 102, the tensile strength of the waterstop can be greatly improved;

[0031] By adding connectors 601 at two places on the waterstop matrix 1, the connector 601 is glued to the second semi-circular protrusion 606 and the second semi-circular groove 605 on the connecting steel belt 2 through the first semi-circular groove 603 and the first semi-circular protrusion 604 in the connecting groove 602, which can expand the contact surface between the connecting steel belt 2 and the connecting groove 602 and make it more stable after gluing.
