Description

Technical Field

[0001] The invention relates to the technical field of water stopping, in particular to a water stopping component and a settlement joint having the water stopping component. Background Art

[0002] Settlement joints are a common structure in construction projects. They are set between two adjacent concrete slabs with different settlement coefficients to prevent damage to the concrete slabs due to differences in settlement coefficients. For example, high-rise buildings will still experience a settlement of 3-5 cm within a certain period of time after completion due to the large load on the upper part of the slab, while the surrounding areas, such as underground garages connected to the underground space of the high-rise building, will not experience significant settlement due to the small load on the upper part; therefore, the concrete slabs of the two need to be cast separately, and settlement joints should be set at the joints to cope with the settlement difference between the two.

[0003] Since the building floors are buried underground and are usually lower than the groundwater level, and since no concrete is poured in the settlement joints, a water-stopping structure needs to be set up in the settlement joints to prevent groundwater from gushing out of the joints. The existing settlement joint water-stopping structure mainly uses a water-stopping rubber belt, which is a sheet-like rubber structure with a circular hole in the middle and raised sides on both sides. When in use, the raised side sheets are respectively poured into the concrete floors on both sides of the settlement joint, and the circular hole structure is left in the settlement joint. When one side of the floor settles, the circular hole structure is pulled and deformed to compensate for the internal tension of the rubber water-stop belt caused by the settlement. In order to improve the waterproof effect, waterproof paste is usually filled in the settlement joint at the bottom of the rubber belt.

[0004] Since the concrete base plates on both sides of the settlement joint are not poured at the same time, but are poured one after another, and the interval may be very long, in order to set the rubber waterstop while casting the concrete base plate, it is necessary to use a special template with an opening for the rubber belt to pass through, or to use a template with separated upper and lower parts; but since the waterstop needs to be seamlessly connected over the entire length of the settlement joint, the openings on the characteristic template usually need to be set continuously, which makes it difficult to set effective connection points for the upper and lower parts of the template (referring to the parts located on the upper and lower sides of the rubber belt), resulting in a difference in the width of the settlement joint on the upper and lower sides of the waterstop, and in the gap between the rubber belt and the concrete base plate. The joint position forms a turning point with a sharp angle, which can easily cause the rubber belt to break when the base plate sinks and pulls the rubber belt; on the other hand, after the base plate on one side is cast and before the base plate on the other side is cast, the other side of the rubber waterstop that has not been sealed by concrete is directly exposed to the construction environment, and often collided and damaged. In addition, since the width of the settlement joint is usually only 5-10cm, the rubber belt exposed to the construction environment is also easily bumped and damaged during the mold erection process before the base plate on the other side is cast; and the damaged rubber belt is difficult to repair effectively, resulting in serious water seepage points after the base plate sinks. Although there are attempts to fill the lower space of the rubber waterstop with waterproof grease in the hope of improving the waterproof effect, since the adjacent rubber belts need to be seamlessly fitted, there is no channel for injecting waterproof grease into the lower part of the waterstop (the oil injection channel will become a water seepage channel later, so such a channel is not desired), so in actual construction, this method is difficult to implement.

[0005] Therefore, how to set a stable, effective and easy-to-construct waterproof structure in the settlement joint has become a problem to be solved urgently in the field. Summary of the invention

[0006] In view of the above-mentioned prior art, the present invention provides a water-stopping component and a settlement joint having the water-stopping component.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific diagrams.

[0033] like Figure 1As shown, the settlement joint and its water-stopping structure in the prior art, the settlement joint is arranged between the settlement side bottom plate 1 (referring to the concrete bottom plate with large upper load, which is easy to cause the bottom plate to settle) and the floating side bottom plate 2 (referring to the concrete bottom plate with small upper load, which is not easy to settle or floats under the action of groundwater pressure); wherein, the settlement side bottom plate 1 is cast before the floating side bottom plate 2, and during the casting process, one side of the water-stopping rubber belt 4 (shown as the left side in the figure) is pre-buried in the concrete structure of the settlement side bottom plate 1, while the other side is exposed to the outside, and is buried in the concrete structure of the floating side bottom plate 2 when the floating side bottom plate 2 is cast. An angle steel 5 is provided at the top of the settlement joint, and a bolt 7 that penetrates the angle steel 5 and is buried in the bottom plate. Through the bolt 7, a detachable rubber belt 6 is provided at the top of the settlement joint to construct a second waterproof structure, and the top of the angle steel 5 is closed by a cover plate 8.

[0034] Example 1

[0035] Different from the existing settlement joint water-stopping structure, this embodiment provides a water-stopping component, such as Figure 2-3 As shown, it is welded as a whole by a water stop unit 9, and the welding points between the components are watertight. The water stop unit 9 includes two water stop plates 10 arranged opposite to each other, the water stop plates 10 are made of steel plates, and the two water stop plates 10 are both provided with water stop wings 11 in the transverse direction on the opposite sides, the water stop wings 11 are made of steel plates, and the two water stop plates 10 are connected on the opposite sides by two connecting plates 13, the connecting plates 13 are made of elastic rubber, the two connecting plates 13 are distributed up and down, and the connecting plates 13 are set as an arc structure, and the water stop wings 11 and the connecting plates 13 are extended as a whole along the length direction of the water stop plates 10. The water stop unit 9 of this embodiment is directly used as a template during construction, thereby eliminating the formwork process and effectively overcoming the problem that the traditional water stop rubber belt needs to pass through the template setting.

[0036] Example 2

[0037] A settlement joint, such as Figure 2-3 As shown, the water stop assembly of Example 1 is used. After the bottom plate is cast, the water stop wing 11 is buried in the concrete to form the water stop part inside the concrete. The outer side of the water stop plate 10 is fixed to the concrete on the side of the settlement joint; the inner sides of the two water stop plates 10 are connected by a deformable connecting plate 13, which can compensate for the misalignment of the water stop plates 10 on both sides caused by settlement through elastic deformation, and can effectively close the channel between the two water stop plates 10 to prevent groundwater from seeping upward from between the two water stop plates 10.

[0038] Example 3

[0039] Different from the water stop assembly of embodiment 1, Figure 4-7As shown, this embodiment is composed of several water-stop units 9 spliced ​​together. The overall structure of this embodiment is a linear structure. Two connecting parts 19 are provided at both ends of the water-stop plate 10. The connecting parts 19 are protrusions with bolt holes, which are used to fix and connect several water-stop units 9 and splice them into the water-stop assembly. In addition, the water-stop wing 11 includes a horizontal part connected to the side of the water-stop plate 10. The outer side of the horizontal part is provided with a downwardly inclined folding edge 111. The two ends of the horizontal part are respectively provided with a longitudinally arranged clamping plate 112 and a clamping groove 113. The clamping groove 113 has a strip groove 114 matching the clamping plate 112; the clamping plate 112 and the strip groove 114 can be sealed and engaged, so that when two adjacent water-stop units 9 are spliced ​​together, the clamping plate 112 of the previous water-stop unit 9 can be sealed and inserted into the strip groove 114 of the next water-stop unit 9, so that the spliced ​​water-stop assembly has a complete and waterproof water-stop wing 11. In addition, similar to the water stop wing 11 , both ends of the connection plate 13 have structures similar to the clamping plate 112 and the clamping groove 113 (not shown in the figure), so that the water stop assembly has a complete and waterproof connection plate 13 .

[0040] Furthermore, the height of the water stop plate 10 is less than the thickness of the concrete bottom plate, a turning plate 12 is provided at the bottom of one water stop plate 10, and a bottom cover plate 15 is provided at the bottom of the other water stop plate 10; the turning plate 12 includes a horizontal section connected to the bottom of the water stop plate 10 and arranged in the transverse direction, and a vertical section connected to the side end of the horizontal section and arranged in the longitudinal direction; the bottom cover plate 15 is arranged opposite to the horizontal section and is not connected, and a slit 20 is formed between the two; the turning plate 12 and the bottom cover plate 15 are integrally extended along the length direction of the water stop plate 10, and are enclosed with the upper connecting plate 13 to form an oil paste cavity 18. The opposite sides of the two water stop plates 10 are provided with a plurality of convex ridges 17, and the opposite sides of the two water stop plates 10 are fixedly connected by a plurality of elastic V-shaped support members 16.

[0041] Example 4

[0042] A settlement joint, such as Figure 8 As shown, the water-stop assembly of Example 3 is used. In this embodiment, the grease cavity 18 can be pre-filled with waterproof grease or rubber, so that when the bottom plate on one side settles and causes the connection plate 13 to deform, the waterproof grease or rubber in the grease cavity 18 is squeezed out from the slit 20 and fills the gap between the concrete bottom plate and the water-stop unit 9 caused by the settlement. The waterproof grease or rubber allows automatic compensation for the loss of waterproof performance that may be caused by settlement, and can also effectively prevent groundwater from invading the connection plate 13, causing it to corrode and break and leak, thereby allowing the water-stop unit 9 to be made of steel with a lower anti-rust standard, thereby reducing costs.

[0043] The support member 16 is used to strengthen the positional relationship between the two waterstop plates 10 and reduce the risk of deformation of the waterstop unit 9 caused by the successive construction of the bottom plates on both sides; the ridge 17 can enhance the bonding strength between the waterstop plate 10 and the concrete, thereby reducing the problem of shortening the water blocking path caused by the separation between the waterstop plate 10 and the concrete during settlement (when the waterstop plate and the concrete are tightly fitted, water cannot pass through the fitting point, but if the two are separated to form a gap, water will seep into the gap).

[0044] Example 5

[0045] Different from the water stop assembly of embodiment 3, Fig. 9 As shown, in this embodiment, the connecting plate 13 is configured as an S-shaped structure, and its side edges are welded to the water stop plate 10 at an inclined angle, so that when the water stop plate 10 on one side sinks with the bottom plate, the connection between the S-shaped connecting plate 13 and the inner side of the water stop plate 10 does not or only slightly deforms, and the main deformation occurs in the middle section of the connecting plate 13, which can effectively prevent the formation of tearing gaps at the connection between the connecting plate 13 and the water stop plate 10 when the connecting plate 13 is deformed.

[0046] Example 6

[0047] Different from the water stop assembly of embodiment 3, Fig.10 As shown, the overall structure of this embodiment is a turning type, so that the water-stop assembly after the connection is completed can perfectly match the shape of the settlement joint around the edge of the bottom plate.

[0048] It can be seen from the above multiple embodiments that, compared with the prior art, the present invention can at least achieve the following beneficial effects: the water-stop component is made of steel plate, has good structural strength, can well adapt to the actual situation of the construction of the bottom plates on both sides of the settlement joint, and is not easy to be damaged during the construction process, thereby ensuring that the actual water-stopping effect after construction can be closer to the designed water-stopping effect; the water-stop component is directly used as a template during the casting of the bottom plate, and there is no need to remove the mold after the concrete is cast, which greatly reduces the construction difficulty (the width of the settlement joint is small, and it is very difficult to remove the mold), and there is no problem of water-stop damage caused by disassembly and assembly of the template in the traditional process of using rubber water-stop; the water-stop component is provided with an oil paste cavity, which can automatically compensate for the loss of water-stop performance during the settlement process, and can effectively prevent the internal waterproof connecting plate from rusting; the water-stop component can be composed of a plurality of water-stop units spliced ​​together, which is simple to construct and can well match various types of settlement joints.

[0049] The above are only implementation modes of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure made using the contents of the present invention's specification and drawings, directly or indirectly used in other related technical fields, are also within the patent protection scope of the present invention.
