Description

Technical Field

[0001] This utility model relates to the field of exterior wall caulking and waterproofing technology, and more specifically, to a caulking and waterproofing device for concrete exterior walls of high-rise residential buildings. Background Technology

[0002] During the construction of high-rise residential buildings, joints are generated in processes such as wall panel splicing and concrete pouring. Due to the height of high-rise residential buildings, the exterior walls are directly exposed to the complex natural environment and face stronger wind pressure and rain impact. When it rains, the rainwater will impact the wall surface with greater kinetic energy under the action of wind pressure. If the joints and construction joints of the exterior walls are not properly sealed, rainwater can easily seep into the interior of the wall along the gaps. If the infiltrated rainwater accumulates in the wall, it will cause steel corrosion, reduce the load-bearing capacity of the building structure, and threaten the overall safety of the high-rise residential building. Traditional caulking strips, once inserted into wall gaps, rely solely on their own elasticity to contact the gap wall, failing to create a multi-layered seal. In high-rise residential buildings, due to the height of the buildings and the strong winds, rainwater is more likely to seep along the wall gaps under wind pressure. The end of the device does not fit tightly against the wall surface, allowing rainwater to easily seep into the joints along the wall panel surface, resulting in a low waterproofing rate and easy loosening. Therefore, a caulking waterproofing device for concrete exterior walls of high-rise residential buildings is proposed. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a caulking waterproofing device for the concrete exterior walls of high-rise residential buildings to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a caulking waterproofing device for the concrete exterior walls of high-rise residential buildings, comprising a sealing strip embedded in the wall joint. After being embedded in the wall joint, the sealing strip generates radial pressure through its own elasticity, tightly fitting against the joint wall. One end of the sealing strip is fixedly connected to an end plate. A strong reinforcing strip is provided in the middle of the sealing strip and the end plate. The strong reinforcing strip can enhance the overall rigidity, resist deformation caused by strong winds, and prevent the strip from being squeezed out by wind pressure. Multiple waterproofing devices are symmetrically fixedly connected to the upper and lower sides of the sealing strip. The water-blocking strip, after being embedded in the joint wall, undergoes elastic deformation to form a sealing structure with the joint wall, blocking rainwater penetration layer by layer and improving waterproofing efficiency. The end plate is fixedly connected to the upper and lower sides near the sealing strip, and the edges of the end plate and the tapered strip are tightly attached to the surface of the outer wall panel to block the path of rainwater seeping into the joint along the surface of the wall panel. The tapered strip forms a secondary seal to improve the sealing strength. A water passage hole is opened at one end of the sealing strip near the end plate to guide the small amount of rainwater that seeps into the inside of the strip to the outside of the wall, preventing rainwater from accumulating in the joint. The sealing strip has a strip-shaped hole at one end away from the end plate, and a positioning hole is formed inside the strip-shaped hole. A pressure strip is provided at the end of the sealing strip away from the end plate. A compression plate is fixedly connected to the side of the pressure strip near the sealing strip. A positioning strip is fixedly connected to one end of the compression plate. Multiple connecting strips are fixedly connected to both the upper and lower ends of the side of the pressure strip near the sealing strip. The pressure strip and the sealing strip are connected through the connecting strips. When the sealing strip is inserted into the gap and squeezes the pressure strip, the connecting strip can be deformed, thereby causing the compression plate to be inserted into the strip-shaped hole until the positioning strip is inserted into the positioning hole, fixing the position of the compression plate. At the same time, it can squeeze and collide with the first end of the sealing strip near the pressure strip, further improving the sealing strength and adapting to joints of larger widths, ensuring that joints of different widths can be tightly sealed, while preventing the pressure strip from falling off.

[0005] Preferably, the sealing strip, end plate, cone strip, waterproof baffle, and pressure strip are all made of rubber. The sealing strip, end plate cone strip, waterproof baffle, and pressure strip are integrally cast to improve the overall protective performance, and can seal during expansion and compression, and can also improve the overall connection strength.

[0006] Preferably, the upper and lower ends of the end plate are both tapered, and the upper and lower ends of the end plate and one end of the tapered strip are all in contact with the wall panel. The end plate and tapered strip can block the path of rainwater seeping into the joint along the surface of the wall panel, and at the same time fill the transition area between the end plate and the wall joint to form a secondary seal.

[0007] Preferably, the reinforcing ribs are made of metal, the cross-sectional shape of the reinforcing ribs is "U", and the number of reinforcing ribs is evenly distributed in the middle of the sealing strip, thereby improving the overall strength.

[0008] Preferably, the opening of the strip hole is configured as a trumpet shape, the cross-sectional shape of the positioning hole is configured as a circle, and the diameter of the positioning hole is greater than the width of the strip hole.

[0009] Preferably, the two side walls of the extrusion insert near the positioning strip are set as inclined surfaces. The positioning strip is adapted to the positioning hole and is set at the flared end of the strip hole. By moving the extrusion insert into the strip hole until the positioning strip is inserted into the positioning hole, the position of the extrusion insert can be fixed. At this time, the connecting strip is squeezed, which can make the connecting strip move to both sides to achieve the function of sealing and fixing. Moreover, the upper and lower sides of the sealing insert near the strip hole expand to increase the connection strength.

[0010] Preferably, one end of the connecting strip is fixedly connected to one end of the sealing strip. The material of the connecting strip can be rubber. One side wall of the waterproof strip is in contact with the wall of the gap in the outer wall panel. By squeezing the strip, the connecting strip is bent to generate axial pressure, which enhances the fit between the strip and the gap wall and prevents the strip from falling off.

[0011] The technical effects and advantages of this utility model are as follows: 1. This utility model firstly uses a sealing strip embedded in the wall joint to generate radial pressure through its own elasticity, which tightly adheres to the joint wall. The end plate and the edge of the tapered strip are tightly adhered to the surface of the outer wall panel, blocking the path of rainwater seeping into the joint along the wall panel surface. The tapered strip forms a secondary seal to improve the sealing strength. At the same time, the waterproof baffle strip undergoes elastic deformation after being embedded in the joint wall, forming a sealing structure with the joint wall, blocking rainwater penetration layer by layer and improving waterproof efficiency. By squeezing the insert plate into the inside of the strip hole, one end of the sealing strip can expand, improving the connection stability and strength. 2. This utility model also features a water-permeable hole that allows incoming rainwater to be positioned between the waterproof strip and the end plate, and then discharged downwards through the water-permeable hole, thus facilitating drainage to the outside of the wall and preventing rainwater from accumulating in the gap. The strong reinforcing strip enhances the overall rigidity, resists deformation caused by strong winds, and prevents the insert strip from being squeezed out by wind pressure. The positioning strip, which is inserted into the positioning hole, can fix the position of the compression insert plate, thereby further improving the tightness of the connection and preventing the sealing insert strip from falling off. In summary, through the interaction of the above-mentioned multiple functions, the path of rainwater seeping into the joints along the surface of the wall panel can be blocked by layers of barriers, thereby improving waterproofing efficiency and enhancing the stability and strength of the connection, preventing the sealing strips from falling off.

[0016] 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.

[0017] As attached Figure 1-3 The high-rise residential building's concrete exterior wall caulking waterproofing device shown includes a sealing strip 1 embedded in the wall joint. After being embedded in the joint, the sealing strip 1 generates radial pressure through its own elasticity, tightly adhering to the joint wall. One end of the sealing strip 1 is fixedly connected to an end plate 3. A reinforcing rib 2 is provided in the middle of the sealing strip 1 and the end plate 3. The reinforcing rib 2 can enhance the overall rigidity, resist deformation caused by strong winds, and prevent the strip from being squeezed out by wind pressure. Multiple waterproof baffles 6 are symmetrically fixedly connected to the upper and lower sides of the sealing strip 1. After entering the joint wall, it undergoes elastic deformation, forming a sealed structure with the joint wall, blocking rainwater penetration layer by layer and improving waterproofing efficiency. The end plate 3 is fixedly connected to the upper and lower sides near the sealing strip 1 with cone strips 4. The edges of the end plate 3 and cone strips 4 are tightly attached to the surface of the outer wall panel, blocking the path of rainwater to seep into the joint along the surface of the wall panel. The cone strips 4 form a secondary seal, improving the sealing strength. A water passage hole 5 is opened at one end of the sealing strip 1 near the end plate 3, which can guide the small amount of rainwater that seeps into the inside of the strip to the outside of the wall, preventing rainwater from accumulating in the joint. The sealing strip 1 has a strip-shaped hole 7 at the end away from the end plate 3. The inner cavity of the strip-shaped hole 7 has a positioning hole 8. The sealing strip 1 has a pressure strip 9 at the end away from the end plate 3. A compression plate 10 is fixedly connected to the side of the pressure strip 9 near the sealing strip 1. A positioning strip 11 is fixedly connected to one end of the compression plate 10. Multiple connecting strips 12 are fixedly connected to both the upper and lower ends of the side of the pressure strip 9 near the sealing strip 1. The pressure strip 9 is connected to the sealing strip 1 through the connecting strips 12. When the sealing strip 1 is inserted into the gap and squeezes the pressure strip 9, the connecting strip 12 can be deformed, so that the compression plate 10 is inserted into the inside of the strip-shaped hole 7 until the positioning strip 11 is inserted into the inside of the positioning hole 8, fixing the position of the compression plate 10. At the same time, it can squeeze and collide the first end of the sealing strip 1 near the pressure strip 9, further improving the sealing strength and adapting to wider joints, ensuring that joints of different widths can be tightly sealed, while preventing the pressure strip from falling off.

[0018] As attached Figure 1-3As shown, the sealing strip 1, end plate 3, cone strip 4, waterproof baffle 6, and pressure strip 9 are all made of rubber. The sealing strip 1, end plate 3, cone strip 4, waterproof baffle 6, and pressure strip 9 are integrally cast. The upper and lower ends of the end plate 3 are both tapered. The upper and lower ends of the end plate 3 and one end of the cone strip 4 are attached to the wall panel. The reinforcing rib 2 is made of metal and has a "U" shaped cross-section. The reinforcing rib 2 is evenly distributed in the middle of the sealing strip 1 to improve the overall protective performance. It can also seal during expansion and compression and improve the overall connection strength. The end plate 3 and cone strip 4 can block the path of rainwater seeping into the joint along the wall panel surface. At the same time, they fill the transition area between the end plate and the wall joint to form a secondary seal. The reinforcing rib 2 improves the overall strength.

[0019] As attached Figure 1-3 As shown, the opening of the strip hole 7 is set as a trumpet-shaped structure, and the cross-sectional shape of the positioning hole 8 is set as a circle. The diameter of the positioning hole 8 is larger than the width of the strip hole 7. The two side walls of the end of the extrusion plate 10 near the positioning strip 11 are set as bevels. The positioning strip 11 is adapted to the positioning hole 8 and is set at the trumpet opening of the strip hole 7. One end of the connecting strip 12 is fixedly connected to one end of the sealing strip 1. The material of the connecting strip 12 can be set as rubber. One side wall of the waterproof strip 6 is attached to the wall of the gap of the outer wall panel. By extruding the plate 10 into the strip hole 7 until the positioning strip 11 is inserted into the interior of the positioning hole 8, the position of the extrusion plate 10 can be fixed. At this time, the connecting strip 12 is squeezed, which can make the connecting strip 12 move to both sides to achieve the function of sealing and fixing. The upper and lower sides of the sealing strip 1 near the end of the strip hole 7 expand to increase the connection strength. By squeezing the pressure strip 9, the connecting strip 12 is bent to generate axial pressure, which enhances the fit between the strip and the gap wall and prevents it from falling off.

[0020] The working principle of this utility model is as follows: When in use, the end of the sealing strip 1 near the pressure strip 9 is inserted into the gap between the two wall panels until both ends of the sealing strip 1 and the end of the cone strip 4 are in contact with the wall surface. This can block the path of rainwater seeping into the joint along the wall panel surface. At the same time, it will squeeze the waterproof strip 6 and make the waterproof strip 6 bend, which will further play the role of blocking water and sealing, and improve the waterproof efficiency. By pressing the wall with the pressure strip 9 at one end of the sealing strip 1, one end of the pressing plate 10 can be inserted into the inside of the strip hole 7 until the positioning strip 11 is inserted into the inside of the positioning hole 8. At this time, the end of the sealing strip 1 near the pressure strip 9 will be pushed up and expanded, which will increase the connection strength of the sealing strip 1 and prevent the sealing strip 1 from falling off. The water passage 5 allows rainwater that accidentally enters the end plate 3 to be discharged to the outside of the wall, preventing rainwater from accumulating in the gap.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
