Description

Technical Field

[0001] The invention relates to the technical field of construction, and in particular to a waterproof deformation joint structure suitable for areas with high rainfall. Background Art

[0002] Deformation joints are structural joints set up in construction projects to adapt to structural deformation caused by temperature changes, humidity changes, settlement, uneven stress distribution, etc. Its main function is to prevent structural cracks, excessive internal stress or local damage caused by these deformations. According to their uses, deformation joints can be subdivided into expansion joints, settlement joints and seismic joints. Expansion joints (temperature joints) are used to absorb expansion or contraction caused by temperature changes; settlement joints are used to separate settlement differences caused by uneven foundation loads; seismic joints are used to reduce collisions or damage to different unit structures during crustal activity. Deformation joints are set up throughout the entire building, including the ground, walls, floors and roofs.

[0003] The expansion joint itself needs to leave a certain amount of space to allow the structure to deform. The existence of this space increases the risk of rainwater infiltration. If the waterproofing treatment is not in place, rainwater may penetrate into the building through the gaps. The seepage may cause corrosion of concrete or steel near the expansion joint, especially metal anchors that are exposed to a humid environment for a long time; it will also directly lead to damage to interior decoration and functional space, such as blistering of walls, mold growth, and floor warping. In areas with high rainfall, the deformation of buildings will be more significant due to factors such as high soil moisture and changes in foundation bearing capacity. How to make the expansion joint waterproof while also adapting to various deformations of the building is an urgent problem to be solved. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a waterproof deformation joint structure suitable for high rainfall areas, which solves the problem of water seepage and deformation at deformation joints in high rainfall areas in the prior art.

[0005] In order to achieve the above-mentioned invention object, the technical solution adopted by the present invention is: a waterproof deformation joint structure suitable for high rainfall areas, comprising a deformation joint and a first concrete and a second concrete arranged in parallel on both sides of the deformation joint;

[0006] A water retaining part is arranged above the deformation joint, and the water retaining part includes a first mounting plate arranged above the first concrete and a second mounting plate arranged above the second concrete; protrusions are arranged at the ends of the first mounting plate and the second mounting plate, and grooves matching the protrusions are arranged above the first concrete and the second concrete; one end of the first mounting plate and the second mounting plate away from the protrusion forms a bite end in the deformation joint, and a gap is arranged at the bite end of the first mounting plate and the second mounting plate; water stop strips are arranged above the first concrete and the second concrete on the first mounting plate and the second mounting plate, and a cover plate is arranged between the two water stop strips;

[0007] A water collecting ditch is arranged below the occlusal end, a microporous drainage pipe is arranged inside the water collecting ditch, and the microporous drainage pipe passes through the side wall of the water collecting trough and extends to the top of the first concrete.

[0008] The beneficial effects of the present invention are as follows: the waterproof deformation joint structure is provided with a water retaining portion above the deformation joint, and the protrusions of the first mounting plate and the second mounting plate are embedded above the first concrete and the second concrete, and a bite end is formed at the end away from the protrusion, so that the mounting plate and the first concrete and the second concrete can fit tightly, reducing the existence of gaps and effectively preventing the leakage of rainwater. The bite end can flexibly respond to the deformation of the building caused by factors such as temperature changes and foundation settlement, ensuring that the structure has a certain deformation capacity while maintaining waterproof performance. The water collection ditch arranged below the bite end can collect a small amount of water that penetrates through the water retaining portion to prevent it from further penetrating downward. The microporous drainage pipe arranged inside the water collection ditch can discharge the water in the water collection ditch. The water stop is located between the first concrete and the second concrete, which can effectively prevent water from penetrating along the joint. The cover plate arranged between the two water stop belts plays a role in protecting the waterproof structure from external physical damage.

[0009] Furthermore, in the waterproof deformation joint structure suitable for areas with high rainfall, elastic columns are arranged at one end of the first mounting plate and the second mounting plate away from the waterstop belt, arc plates are arranged above the two elastic columns, and the two arc plates are arranged in an alternating and overlapping manner.

[0010] The beneficial effect of adopting the above further scheme is that when the building faces temperature changes, foundation settlement or other external forces, the elastic column can effectively absorb and disperse the stress caused by these deformations. The shape of the curved plate can effectively guide the flow of rainwater and reduce the possibility of water retention or backflow in the deformation joint area; the staggered overlapping arrangement of the two curved plates ensures that when the building undergoes a large deformation, the overlapping part can still keep the deformation joint covered at a certain distance, which not only ensures the sealing of the deformation joint in a dynamic environment, but also greatly reduces the risk of structural damage caused by building deformation.

[0011] Furthermore, in the above waterproof deformation joint structure suitable for high rainfall areas, a waterproof layer is provided between the first concrete and the first mounting plate; and a waterproof layer is provided between the second concrete and the second mounting plate.

[0012] The beneficial effect of adopting the above further solution is that the waterproof layer can effectively block external moisture and prevent it from penetrating into the building through the gap between the concrete and the mounting plate, thereby protecting the integrity and safety of the building structure. The waterproof layer material has a certain elasticity and adhesion, and can be tightly combined with the concrete and the mounting plate to form a whole, thereby increasing the connection strength between the various components of the structure.

[0013] Furthermore, in the waterproof deformation joint structure suitable for areas with high rainfall, a water pump is provided at one end of the microporous drainage pipe away from the water collection tank.

[0014] The beneficial effect of adopting the above further scheme is: by setting up a water pump, the accumulated water in the microporous drainage pipe can be actively pumped out, thereby accelerating the drainage process. Compared with passive drainage, it is more efficient and can effectively deal with the infiltration of large amounts of rainwater in a short period of time, and prevent leakage problems caused by poor drainage.

[0015] Furthermore, the above-mentioned waterproof deformation joint structure suitable for high rainfall areas is provided with a waterproof slurry layer at the bite end.

[0016] The beneficial effects of adopting the above further scheme are as follows: from the perspective of waterproof performance, the addition of the waterproof slurry layer improves the anti-seepage ability of the deformation joint structure in a high rainfall environment. Since the slurry layer has excellent water resistance and sealing properties, it can effectively prevent rainwater from penetrating into the structure through the gaps at the bite end. From the perspective of structural stability, the waterproof slurry layer not only enhances the connection strength of the bite end, but also has a certain buffering effect on structural deformation through its flexibility. When dealing with small deformations of the building caused by crustal movement, temperature changes, etc., it can absorb and disperse the stress generated by these deformations to a certain extent, preventing the structure from being damaged due to stress concentration.

[0017] Furthermore, the above-mentioned waterproof deformation joint structure is suitable for areas with high rainfall, and the elastic column includes an outer shell and a spring arranged inside the outer shell, the spring runs through the outer shell, and connectors are arranged at both ends of the spring, and the two connectors are respectively connected to the water retaining part and the arc plate.

[0018] The beneficial effect of adopting the above further solution is that through the elastic effect of the spring, the deformation joint structure has better elasticity and adaptability when responding to external pressure or deformation. The connectors at both ends of the spring are tightly connected to the water retaining part and the arc plate respectively, ensuring the tight fit between the various components of the deformation joint structure. The shell can protect the spring from contact with the external environment and avoid corrosion by rain and air.

[0019] Furthermore, in the waterproof deformation joint structure suitable for high rainfall areas, the ditch is fixedly connected to the side walls of the first concrete and the second concrete through expansion bolts; the top of the ditch is fixedly connected to the lower ends of the first mounting plate and the second mounting plate through bolts.

[0020] The beneficial effects of the present invention are as follows: the waterproof deformation joint structure of the present invention realizes efficient waterproofing in high rainfall areas through water retaining design, multi-level waterproof system, efficient water collection and drainage system, flexible deformation adaptability and meticulous waterproof slurry layer treatment. Specifically, the first mounting plate and the second mounting plate are symmetrically arranged on both sides of the deformation joint, and the design of the protrusion and the bite end effectively blocks the rainwater from above. The design of the bite end ensures that the two mounting plates fit tightly at the deformation joint, and can maintain a certain waterproof effect even in the case of slight deformation. The water collection ditch is located below the bite end, which can collect water that penetrates into the deformation joint through other channels, and the microporous drainage pipe is responsible for draining this water. The setting of the water pump ensures that the drainage system can continue to operate efficiently under high rainfall conditions to prevent water accumulation from damaging the structure. The design of the elastic column and the arc plate gives the structure good deformation adaptability; the spring is arranged inside the elastic column, and the height and angle can be flexibly adjusted according to the deformation of the deformation joint to ensure that the water retaining part always maintains close contact with the concrete surface. The staggered overlapping arrangement of the arc-shaped plates not only increases the stability of the structure, but also can provide a certain buffering effect during the deformation process, thereby preventing structural damage caused by excessive deformation.

DETAILED DESCRIPTION

[0025] The specific implementation modes of the present invention are described below so that those skilled in the art can understand the present invention. However, it should be clear that the present invention is not limited to the scope of the specific implementation modes. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, these changes are obvious, and all inventions and creations utilizing the concept of the present invention are protected.

[0026] like Figures 1 to 3As shown, this embodiment provides a waterproof expansion joint structure suitable for areas with high rainfall, including an expansion joint 1 body, a waterproof water retaining component, a ditch 11, a drainage device and a sealing auxiliary component. The expansion joint 1 body includes the expansion joint 1 and a first concrete 2 and a second concrete 3 arranged in parallel on both sides of the expansion joint 1.

[0027] In order to cope with the impact of precipitation in high rainfall areas, a water retaining part is provided above the deformation joint 1, and the water retaining part includes a first mounting plate 4 provided above the first concrete 2 and a second mounting plate 5 provided above the second concrete 3. The function of the water retaining part is to prevent rainwater from entering the interior of the building structure through the deformation joint 1, especially during heavy precipitation, to prevent moisture from penetrating along the deformation joint 1. In this embodiment, the first mounting plate 4 and the second mounting plate 5 are made of stainless steel 304, which has excellent corrosion resistance and can adapt to the harsh conditions of long-term exposure to high rainfall environments.

[0028] The ends of the first mounting plate 4 and the second mounting plate 5 are both provided with protrusions 6, and the protrusions 6 embed the first mounting plate 4 and the second mounting plate 5 above the first concrete 2 and the second concrete 3 to form a tight waterproof closed structure.

[0029] The ends of the first mounting plate 4 and the second mounting plate 5 away from the protrusion 6 form a bite end 7 in the deformation joint 1, so that a certain sealing state is formed between the plate and the deformation joint 1 to prevent rainwater from penetrating. A waterproof slurry layer 16 is provided at the bite end 7, and a gap 8 is provided at the bite end 7 of the first mounting plate 4 and the second mounting plate 5 for setting the waterproof slurry layer 16. In order to enhance the waterproof effect, water stop strips 9 are respectively provided above the first mounting plate 4 and the second mounting plate 5. The water stop strips 9 can effectively block the penetration of water and ensure that water is not easy to penetrate from the gap 8. The cover plate 10 provided between the two water stop strips 9 plays a role in protecting the waterproof structure from external physical damage.

[0030] A water collection ditch 11 is provided below the occlusal end 7, which can collect a small amount of water that penetrates through the water retaining part to prevent it from further penetrating downward. A microporous drainage pipe 12 is provided inside the water collection ditch 11, and the microporous drainage pipe 12 passes through the side wall of the water collection tank and extends to the top of the first concrete 2. The design of the microporous pipe allows water to be discharged through the pipe to ensure that the structure is not soaked by water. A water pump is provided at the end of the microporous drainage pipe 12 away from the water collection tank, ensuring that the drainage system can continue to operate efficiently under high rainfall conditions to prevent water accumulation from damaging the structure.

[0031] The first mounting plate 4 and the second mounting plate 5 are both provided with elastic columns 13 at one end away from the water stop 9. The elastic columns 13 include a housing 17 and a spring 18 provided inside the housing 17. In this embodiment, the spring 18 is made of 65Mn spring steel, which has good elasticity and fatigue properties. The spring 18 runs through the housing 17. Connectors 19 are provided at both ends of the spring 18. The two connectors 19 are respectively connected to the water retaining portion and the arc plate 14. The design purpose of the elastic columns 13 is to adapt to the possible displacement of the building during the deformation process, and to ensure that the deformation joint 1 still maintains good sealing performance during the displacement process.

[0032] The two elastic columns 13 are each provided with an arc plate 14. In this embodiment, the two arc plates 14 are made of aluminum alloy and sprayed with an anti-corrosion coating on their surfaces, so that they can withstand long-term erosion by rainwater. The two arc plates 14 are staggered and overlapped, so that when the building undergoes a large deformation, the overlapped part can still shield the deformation joint 1 at a certain distance, which not only ensures the sealing of the deformation joint 1 in a dynamic environment, but also greatly reduces the risk of structural damage caused by building deformation.

[0033] A waterproof layer 15 is provided between the first concrete 2 and the first mounting plate 4, and a waterproof layer 15 is provided between the second concrete 3 and the second mounting plate 5. The waterproof layer 15 can effectively block external moisture and prevent it from penetrating into the building through the gap 8 between the concrete and the mounting plate, thereby protecting the integrity and safety of the building structure.

[0034] The installation steps of the waterproof deformation joint 1 structure are as follows:

[0035] Pretreatment: First clean the deformation joint 1 and the surrounding area to ensure that there is no sand and impurities, and then chisel two grooves matching the first mounting plate 4 and the second mounting plate 5 above the first concrete 2 and the second concrete 3.

[0036] Install the microporous drainage pipe 12: extend the microporous drainage pipe 12 along the top of the first concrete 2 into the deformation joint 1, and connect the end of the microporous drainage pipe 12 away from the deformation joint 1 to the water pump to complete the fixation.

[0037] Install the water collection tank: pass the microporous drainage pipe 12 through the side wall of the water collection tank, and fix the water collection tank inside the deformation joint 1. The water collection ditch 11 is fixed to the first concrete 2 and the second concrete 3 by expansion bolts.

[0038] Install waterproof layer 15: a waterproof layer 15 is arranged on the contact surface between the first concrete 2 and the first mounting plate 4, and between the second concrete 3 and the second mounting plate 5. The waterproof layer 15 is modified asphalt or polyurethane waterproof coating.

[0039] Install the water retaining part: fix the first mounting plate 4 and the second mounting plate 5 on the corresponding concrete surface, and fix the upper end of the water collecting trough to the lower ends of the first mounting plate 4 and the second mounting plate 5 by bolts, adjust the position of the bite end 7 to ensure the gap is aligned, and then set the cover plate 10 on the first mounting plate 4 and the second mounting plate 5.

[0040] Set the waterproof slurry layer 16: lift the cover plate 10 and pour the waterproof slurry into the bite end 7. The waterproof slurry can completely fill the bite end 7 through the gap 8 of the bite end 7. After the waterproof slurry solidifies and takes shape, the waterproof slurry at the bite end 7 forms a waterproof slurry layer 16.

[0041] Install the elastic column 13 and the arc plate 14: fix the elastic column 13 to the end of the water retaining part away from the water stop belt 9, install the arc plate 14 and adjust the staggered position to ensure the waterproof performance.

[0042] The waterproof deformation joint 1 structure of the present invention can effectively prevent rainwater leakage and ensure structural safety through a multi-layer waterproof design, such as the water retaining part, the water stop strip 9, the waterproof layer 15, the microporous drainage pipe 12, etc. cooperating with each other.

[0043] Through the design of the elastic column 13 and the arc-shaped plate 14, the deformation joint 1 can adapt to the deformation of the building such as thermal expansion and contraction, settlement, etc., and avoid moisture penetration caused by structural changes.

[0044] The design of the water collecting ditch 11 and the microporous drainage pipe 12 allows the accumulated water in the deformation joint 1 to be quickly discharged, thereby avoiding the long-term impact of the accumulated water on the building. The structure can be conveniently inspected and maintained daily, ensuring the waterproof effect in long-term use.
