Description

Technical Field

[0001] This utility model relates to the field of rubber waterstop technology, specifically a composite rubber waterstop. Background Technology

[0002] Composite rubber waterstops are waterproof materials made of natural rubber and synthetic rubber as the main base materials, combined with fibers, metal skeletons or other functional layers.

[0003] The utility model with announcement number CN220814316U discloses a composite rubber waterstop, which includes a composite waterstop with an intermediate interlayer symmetrically arranged inside. The intermediate interlayer has a partition layer. Several connecting rubber strips are fixed at equal distances between the outer wall of the partition layer and the inner wall of the intermediate interlayer. A buffer cavity is provided between two connecting rubber strips. A loading cavity is opened in the partition layer and a composite reactive material is provided in the loading cavity.

[0004] The above technical solution involves setting a buffer cavity on the outer wall of the composite reactive material. When the composite reactive material expands or cures due to an external excitation source, it first compresses the composite waterstop through the connecting rubber strip, causing the composite waterstop to adhere tightly to the surrounding concrete and seal the gap. If the composite reactive material continues to expand or cure, the buffer cavity can act as a buffer, preventing excessive expansion or curing of the composite reactive material from damaging or breaking the composite waterstop. However, the waterstop undergoes elastic deformation due to the expansion, settlement, or vibration of the concrete structure. The increased joint width can cause tensile breakage of the waterstop, and the deformation and movement affect waterproofing. Since the waterstop is embedded in the concrete on both sides, it cannot increase frictional resistance. The expansion of the concrete can compress the waterstop, easily causing it to break. This does not increase sealing performance or reduce the impact of breakage on waterproofing. Utility Model Content

[0005] The purpose of this invention is to provide a composite rubber waterstop to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A composite rubber waterstop includes a corrugated belt and side waterstops connected to both sides of the corrugated belt. The corrugated belt has several reinforcing ribs in the middle, and both ends of the reinforcing ribs are connected by connecting belts. The side waterstops have several deformation holes on their sides, and slots are provided in the side waterstops corresponding to the reinforcing ribs. Deformation sleeves are provided at the outer ends of the side waterstops, and several baffles are provided on the upper and lower surfaces of the side waterstops.

[0008] Furthermore, the corrugated strip is wave-shaped, and the corrugated strip and the side water-blocking strip are integrally formed.

[0009] In this invention, both the corrugated belt and the side water-blocking belt are made of neoprene rubber, which increases aging resistance, durability, and tear resistance.

[0010] Specifically, the reinforcing ribs are evenly spaced and all of them penetrate the corrugated strip. The width of the outer wall of the reinforcing ribs is adapted to the width of the inner wall of the slot.

[0011] In this invention, the reinforcing ribs are made of steel wire to increase the tensile strength of the corrugated belt and the side water baffle. Furthermore, multiple reinforcing ribs are inserted into slots to increase the stability of the combination of the side water baffle and the corrugated belt.

[0012] It should be noted that the deformation sleeve and the outer end of the side water baffle are integrally formed. The deformation sleeve has a cavity inside, and an annular groove is formed in the area between the inner wall of the cavity and the outer wall of the deformation sleeve. The width of the inner wall of the annular groove is adapted to the width of the outer wall of the connecting strip, and the inside of the annular groove is connected to the inside of the slot.

[0013] In this invention, the cavity increases the space for the deformation sleeve to deform. The side water-blocking strip is embedded in the concrete, and the expansion of the concrete compresses and squeezes the deformation sleeve to fit, reducing the risk of the deformation sleeve breaking after deformation and affecting waterproofing.

[0014] Furthermore, the deformation holes are arranged in a matrix, with two rows of deformation holes on each side baffle, and the upper row of deformation holes and the lower row of deformation holes are arranged alternately.

[0015] In this invention, the combination of multiple deformation holes increases the side water baffle strip's resistance to compression deformation. When the side water baffle strip is compressed and deformed, it breaks and loses its waterproof function. The two rows of deformation holes are staggered to increase the deformation range of the side water baffle strip and increase its resistance to compression.

[0016] Specifically, the baffles are evenly spaced and the baffles and the side water-blocking strips are integrally formed. The outer ends of the baffles are inclined toward the deformation sleeve, and the inner ends of the baffles are inclined toward the corrugated strip.

[0017] In this invention, multiple baffles are distributed on the outer walls of both sides of the side water-blocking strip to increase the contact area. The baffles are inclined to increase the resistance to contact with the concrete, thereby increasing the stability of the side water-blocking strip and the concrete insertion installation.

[0018] In addition, the connecting strip and the reinforcing rib are integrally formed, the connecting strip passes through the deformation sleeve, and the reinforcing rib passes through the corrugated strip and the side water baffle, and the first and second ends are connected.

[0019] In this invention, the combination of reinforcing ribs and connecting strips increases the overall structural toughness, enhances tensile strength, and reduces the risk of breakage due to tension, thus preventing loss of the water-stopping and sealing effect.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model, by setting a corrugated belt in conjunction with a side water-blocking belt, increases the ductility of the corrugated belt when it is stretched and unfolded. The concrete structure undergoes elastic deformation due to expansion, settlement or vibration, and the joint width increases, reducing tensile breakage damage. With the cooperation of multiple deformation holes, the side water-blocking belt is increased to resist extrusion deformation, reducing the impact of extrusion breakage on long-term use. Furthermore, with the cooperation of the deformation sleeve with a cavity, the friction between the two ends of the side water-blocking belt and the concrete is increased.

[0022] 2. This utility model increases the toughness and tensile strength between the corrugated belt, side water-blocking belt, and deformation sleeve by setting multiple connecting strips and corresponding reinforcing strips. With the cooperation of multiple baffles, the contact area on both sides of the side water-blocking belt is increased, thereby increasing the resistance to concrete. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-4 This embodiment provides a technical solution:

[0034] A composite rubber waterstop includes a corrugated strip 1 and side water-blocking strips 2 connected to both sides of the corrugated strip 1. The corrugated strip 1 is wavy in shape, and the corrugated strip 1 and the side water-blocking strips 2 are integrally formed.

[0035] In this invention, both the corrugated belt 1 and the side water-blocking belt 2 are made of neoprene rubber, which increases aging resistance, durability, and tear resistance.

[0036] Furthermore, the corrugated belt 1 has several reinforcing ribs 10 in the middle, the reinforcing ribs 10 are evenly distributed, and all the reinforcing ribs 10 penetrate the corrugated belt 1. The width of the outer wall of the reinforcing ribs 10 is adapted to the width of the inner wall of the slot 21.

[0037] In this utility model, the reinforcing ribs 10 are made of steel wire, which increases the tensile strength of the corrugated belt 1 and the side water baffle 2. In addition, multiple reinforcing ribs 10 are inserted into the slots 21 to increase the stability of the combination of the side water baffle 2 and the corrugated belt 1.

[0038] Specifically, both ends of the reinforcing rib 10 are connected by a connecting strip 100. Several deformation holes 20 are provided on the side of the side water baffle 2. The deformation holes 20 are distributed in a matrix. Each side water baffle 2 has two rows of deformation holes 20, with the upper row of deformation holes 20 and the lower row of deformation holes 20 arranged alternately.

[0039] In this invention, the combination of multiple deformation holes 20 increases the side water baffle 2's resistance to compression deformation. When the side water baffle 2 is compressed and deformed, it breaks and loses its waterproof function. The two rows of deformation holes 20 are staggered to increase the deformation range of the side water baffle 2 and increase its resistance to compression.

[0040] It should be noted that a slot 21 is provided in the side water baffle 2 at the position corresponding to the reinforcing rib 10, and a deformation sleeve 3 is provided at the outer end of the side water baffle 2. The deformation sleeve 3 and the outer end of the side water baffle 2 are integrally formed. A cavity 30 is provided inside the deformation sleeve 3. An annular groove 31 is also provided in the area between the inner wall of the cavity 30 and the outer wall of the deformation sleeve 3. The width of the inner wall of the annular groove 31 is adapted to the width of the outer wall of the connecting strip 100. The interior of the annular groove 31 is connected to the interior of the slot 21.

[0041] In this invention, the cavity 30 increases the space for deformation of the deformation sleeve 3. The side water-blocking strip 2 is embedded in the concrete. The expansion of the concrete compresses and squeezes the deformation sleeve 3 to fit together, reducing the risk of the deformation sleeve 3 breaking after deformation and affecting waterproofing.

[0042] Secondly, the upper and lower surfaces of the side water baffle 2 are provided with several baffle strips 4.

[0043] It is worth adding that the baffles 4 are evenly spaced and the baffles 4 and the side water-blocking strips 2 are integrally formed. The outer ends of the baffles 4 are inclined toward the deformation sleeves 3, and the inner ends of the baffles 4 are inclined toward the corrugated strips 1.

[0044] In this invention, multiple baffles 4 are distributed on the outer walls of both sides of the side water-blocking strip 2 to increase the contact area. The baffles 4 are inclined to increase the resistance to contact with the concrete, thereby increasing the stability of the side water-blocking strip 2 and the concrete insertion installation.

[0045] Furthermore, the connecting strip 100 and the reinforcing rib strip 10 are integrally formed, the connecting strip 100 passes through the deformation sleeve 3, and the reinforcing rib strip 10 passes through the corrugated strip 1 and the side water-blocking strip 2, and the first and last ends are connected.

[0046] In this utility model, the reinforcing rib 10 and the connecting rib 100 work together to increase the overall structural toughness, increase tensile strength, reduce the risk of breakage caused by tension, and prevent loss of the water-stopping and sealing effect.

[0047] When using the composite rubber waterstop in this embodiment, the connecting strip 100 is first installed in the corresponding annular groove 31, the connecting strip 100 is combined with the reinforcing strip 10, the reinforcing strip 10 is inserted into the slot 21, the reinforcing strip 10 increases the toughness between the corrugated strip 1 and the side waterstop 2, and multiple baffles 4 are distributed on both sides of the corresponding side waterstop 2.

[0048] When waterstop installation is required, the corrugated strip 1 is placed in the gap between the concrete structures. The side waterstop 2 extends into the concrete structure layer. With the cooperation of the deformation sleeve 3 with cavity 30, the end resistance is increased. With the cooperation of multiple baffles 4, the contact area is further increased, increasing the resistance. When the joint width increases, the corrugated strip 1 is pulled and extended, reducing the impact of tensile breakage. The concrete solidifies and expands, squeezing the deformation sleeve 3 and the side waterstop 2. With the cooperation of cavity 30 and deformation hole 20, the deformation range is increased. The outer walls of the deformation sleeve 3 and the side waterstop 2 are both attached to the concrete structure, reducing the increase of gaps and loss of waterstop function. The overall structure is simple, and with the cooperation of the reinforcing strip 10, the overall tensile strength is increased.
