Description

Technical Field

[0001] This utility model relates to the field of rubber waterstop technology, and in particular to an embedded anti-cracking rubber waterstop. Background Technology

[0002] Currently, reinforced concrete is the primary structural material for buildings. To meet requirements for earthquake resistance, settlement tolerance, and crack resistance, concrete structures must incorporate construction joints and expansion joints at certain locations. These joints often suffer from weak concrete bonding or pre-existing gaps. In such cases, relying solely on an external flexible waterproofing layer is insufficient. Rubber waterstops are then used to enhance waterproofing. Waterstops for building waterproofing are categorized into embedded waterstops, externally applied waterstops, and removable waterstops. Embedded waterstops are those installed between two concrete components.

[0003] In practical use, leakage of embedded waterstops is often caused by localized breakage. Extensive practical construction experience shows that embedded waterstops are most prone to tearing at the junction with the concrete block. Deformation at construction joints and expansion joints causes localized tension or compression on the embedded waterstop. Simultaneously, if there are sharp-edged stones at the junction of the concrete block and the embedded waterstop facing the construction joint or expansion joint, these edges can scratch the waterstop surface, creating stress and strain concentration. Under long-term harsh environmental conditions, this area is prone to cracking, leading to leakage.

[0004] Therefore, it is necessary to develop a centrally embedded anti-cracking rubber waterstop to address the aforementioned defects. Utility Model Content

[0005] The purpose of this invention is to provide an embedded anti-cracking rubber waterstop, which has a burr-like part at the joint edge of the concrete body to reduce the contact between the crushed stone in the concrete and the main body of the waterstop during the pouring process, thus significantly improving the crack resistance of the rubber waterstop.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model relates to an embedded anti-cracking rubber waterstop, which includes a waterstop body. The waterstop body has four burrs at the junction with the edge of the concrete body. The burrs are integrally formed on the surface of the waterstop body.

[0008] Furthermore, the burr portion includes a plurality of columnar burrs, which are arranged perpendicular to the surface of the waterstop body; the plurality of columnar burrs are arranged at equal intervals and the interval between adjacent columnar burrs is no greater than 8 mm.

[0009] Furthermore, the columnar burr is a cylindrical or conical rubber column, the height of the rubber column is not less than 5 mm, and the top of the rubber column is set as a ball head.

[0010] Furthermore, the waterstop body is applied to building expansion joints, and an expansion hole is provided in the middle of the waterstop body. Multiple parallel waterstop lines are symmetrically arranged on the upper and lower surfaces of the waterstop body on both sides of the expansion hole.

[0011] Furthermore, the waterstop body is applied to construction joints in buildings. The waterstop body is in the form of a flat strip, and multiple parallel waterstop lines are provided on the outer side of the bristle portion.

[0012] Furthermore, the waterstop body also includes steel edges, and two steel edges are symmetrically vulcanized and bonded to both sides of the waterstop body.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0014] This utility model of an embedded crack-resistant rubber waterstop features bristles on the edges of the concrete facing the crack. These bristles prevent aggregate particles in the concrete from approaching the surface of the waterstop during concrete pouring, allowing only fine aggregate and grout to penetrate. Therefore, over long-term use, this reduces the risk of scratches and abrasions to the waterstop surface caused by aggregate contact. By incorporating these bristles at the joint edges of the concrete, this embedded crack-resistant rubber waterstop significantly improves the crack resistance of the rubber waterstop.

[0015] Furthermore, by rationally setting the diameter, height, and adjacent spacing of the columnar burrs, it is possible to effectively prevent large stones from contacting the surface of the waterstop body, thus improving protective performance. On the other hand, it also allows the grout to smoothly enter the periphery of the columnar burrs, avoiding the formation of voids. The deformation holes in the middle of the waterstop body improve its resistance to deformation; when deformation occurs, the deformation holes are squeezed or stretched. The waterstop line increases the bonding strength with the concrete, reducing the inward extension of water stains along the interface gaps. Using a waterstop body with burrs can also significantly improve the cracking of waterstops used in construction joints. Combined with steel-edged waterstops, it significantly improves the bonding strength between the waterstop body and the concrete while also providing tear resistance. Attached Figure Description

[0022] The core of this utility model is to provide an embedded anti-cracking rubber waterstop, which has a burr-like part set at the joint edge of the concrete body to reduce the contact between the crushed stone in the concrete and the main body of the waterstop during the pouring process, thus significantly improving the crack resistance of the rubber waterstop.

[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown, the embedded anti-cracking rubber waterstop of this utility model includes a waterstop body 1. The waterstop body 1 has bristles 103 at the junction with the edge of the concrete body 2. The bristles 103 are also arranged along the length of the waterstop body 1. There are four bristles 103, located at the edges of the concrete body 2 facing the gap filling plate 3. The bristles 103 are integrally formed on the surface of the waterstop body 1, meaning they are also made of rubber.

[0028] By setting the bristles 103 at the edge of the concrete body 2 facing the gap, the bristles 103 can prevent the gravel in the concrete from approaching the surface of the waterstop body 1 during the concrete pouring process, allowing only fine stones and slurry to penetrate. Therefore, during long-term use, the contact scratches and damage to the surface of the waterstop body 1 caused by the gravel edges are reduced. This utility model of embedded anti-cracking rubber waterstop, by setting bristles at the joint edge of the concrete body, reduces the contact between the gravel in the concrete and the waterstop body during the pouring process, significantly improving the crack resistance of the rubber waterstop.

[0029] In the specific implementation of this first embodiment, as follows Figure 1 As shown, the burr portion 103 includes a plurality of columnar burrs, which are arranged perpendicular to the surface of the waterstop body 1. The plurality of columnar burrs are arranged at equal intervals, and the distance between adjacent columnar burrs is no greater than 8 mm.

[0030] Specifically, such as Figure 1 As shown, the columnar burr is a cylindrical or conical rubber column with a height of not less than 5 mm, a bottom diameter of not less than 4 mm, and a ball-shaped top.

[0031] By reasonably setting the diameter, height, and adjacent spacing of the columnar burrs, it is possible to effectively prevent large gravel from contacting the surface of the waterstop body 1, thus improving the protective performance; on the other hand, it also allows the slurry to smoothly enter the periphery of the columnar burrs, avoiding the formation of voids.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, the waterstop body 1 is applied to building deformation joints, such as expansion joints, settlement joints, or seismic joints. The waterstop body 1 has a deformation hole 101 in the middle, which is a circular tube shape and extends the entire length of the tube. Multiple parallel waterstop lines 102 are symmetrically arranged on both sides of the deformation hole 101 on the upper and lower surfaces of the waterstop body 1. That is, the waterstop lines 102 extend the entire length of the tube.

[0033] The deformation resistance is improved by setting deformation holes 101 in the middle of the main body 1 of the waterstop. When deformation occurs, the deformation holes 101 are squeezed or stretched. The setting of the waterstop line 102 increases the bonding strength with the concrete body 2 and reduces the extension of water stains along the joint interface.

[0034] Example 2

[0035] like Figure 3 As shown, the difference from Embodiment 1 above is that in this embodiment, the waterstop body 1 is applied to the construction joint of the building, and the waterstop body 1 is in the form of a flat strip, that is, without deformation holes 101. Multiple parallel waterstop lines 102 are provided on the outer side of the bristle portion 103.

[0036] Although the deformation of the construction joint is small, the waterstop body 1 is still subject to twisting and compression by two concrete bodies 2, and is also prone to being damaged by gravel. Therefore, using a waterstop body 1 with a barbed part 103 can significantly improve the cracking of the waterstop used on the construction joint.

[0037] Example 3

[0038] like Figure 4 As shown, the waterstop is improved based on the above embodiment 1 and applied to a steel-edged waterstop. The waterstop body 1 also includes steel edges 104, with two steel edges 104 symmetrically vulcanized and bonded to both sides of the waterstop body 1.

[0039] When combined with a steel-edged waterstop, it significantly improves the bonding strength between the waterstop body 1 and the concrete body 2, while also providing tear resistance.

[0040] In summary, this utility model of an embedded anti-cracking rubber waterstop, by setting bristles 103 at the edge of the concrete body 2 facing the crack, can prevent gravel in the concrete from approaching the surface of the waterstop body 1 during the concrete pouring process, allowing only fine stones and grout to penetrate. Therefore, during long-term use, it reduces the risk of scratches and abrasions to the surface of the waterstop body 1 caused by the contact of gravel edges. This utility model of an embedded anti-cracking rubber waterstop, by setting bristles at the joint edge of the concrete body, reduces the contact between gravel in the concrete and the waterstop body during pouring, significantly improving the crack resistance of the rubber waterstop. Furthermore, by reasonably setting the diameter, height, and adjacent spacing of the columnar bristles, it can effectively prevent larger gravel from contacting the surface of the waterstop body 1, improving protective performance; on the other hand, it can also allow grout to smoothly enter the periphery of the columnar bristles, avoiding the formation of voids. The deformation hole 101 in the middle of the waterstop body 1 improves its resistance to deformation; when deformation occurs, the deformation hole 101 is compressed or stretched. The waterstop line 102 increases the bonding strength with the concrete body 2, reducing the inward extension of water stains along the interface gap. Using a waterstop body 1 with bristles 103 can also significantly improve the cracking of waterstops used in construction joints. Combined with a steel-edged waterstop, it significantly improves the bonding strength between the waterstop body 1 and the concrete body 2 while also providing tear resistance.
