Technical Field
[0001] This utility model relates to the field of waterproof backing board joint sealing technology, and in particular to a joint sealing device for waterproof backing boards. Background Technology
[0002] Currently, the treatment of joints in waterproof backing boards remains a significant technical challenge in the construction engineering field. Traditional methods for treating joints in waterproof backing boards often have numerous shortcomings, leading to leakage problems at the joints and consequently affecting the waterproof performance and service life of the entire building structure.
[0003] Traditional joint treatment materials and techniques are difficult to guarantee a complete seal at the joints. Due to the special nature of waterproof backing materials and the complexity of the construction environment, it is often difficult to achieve a seamless connection at the joints, thus leaving potential leakage risks. On the other hand, even if certain sealing materials or techniques are used, they are often difficult to be widely used in actual projects due to unstable material performance, complex construction processes, or high costs.
[0004] To address these issues, we propose a joint sealing device for waterproof backing boards. This device effectively seals the joints of the waterproof backing boards, preventing leakage, while also possessing good durability and maintainability. Utility Model Content
[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a joint sealing device for waterproof backing boards.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A joint sealing device for a waterproof backing board includes: a waterproof backing board, the waterproof backing board having two sides, and two sets of the waterproof backing board having a butt groove on the top of each side, a joint sealing mechanism installed in the two sets of butt grooves, the joint sealing mechanism having a concave shape in the middle, and an edge sealing component installed in the middle of the joint sealing mechanism, the edge sealing component being on the same horizontal plane as the side walls of the two sets of waterproof backing boards.
[0008] Preferably, the joint sealing mechanism includes a connecting cover installed between two sets of waterproof backing plates, mating plates fixedly installed on the bottom sides of both ends of the connecting cover, multiple sets of equidistantly distributed mounting holes in the middle of the connecting cover, and splicing plates fixedly installed on the top of the connecting cover. The two sides of the connecting cover correspond to the two sets of mating grooves, and the two sets of splicing plates are on the same horizontal plane as the sides of the two sets of waterproof backing plates. The mating plates are made of polystyrene material, and the surfaces of the mating grooves and the mating plates are coated with waterproof adhesive, which can connect the two sets of waterproof backing plates.
[0009] Preferably, multiple sets of equidistant expansion nuts are installed on the wall between the two sets of waterproof backing boards, and mounting bolts are installed in the mounting holes corresponding to the two sets of expansion nuts, so as to facilitate the correspondence with the mounting holes.
[0010] Preferably, the waterproof backing board consists of two sets of mortar outer boards, two sets of fiberglass mesh cloth, and one set of extruded polystyrene board. The two sets of mortar outer boards are distributed on both sides of the waterproof backing board, and fiberglass mesh cloth is bonded to the inner side of both sets of mortar outer boards. The extruded polystyrene board is bonded and installed between the two sets of fiberglass mesh cloth to ensure the waterproof effect of the waterproof backing board.
[0011] Preferably, the edge sealing assembly includes slots opened on both sides of the inner cavity of the connecting cover, an inner buckle plate inserted into the inner cavity of the connecting cover, and a buckle block fixedly installed on both sides of the inner buckle plate. The two sets of buckle blocks correspond to the two sets of slots respectively. The inner buckle plate has a T-shaped cross-section and can seal the edge of the joint sealing mechanism.
[0012] Preferably, a sealing gasket is inserted into the inner cavity of the connecting cover, and a compression head is fixedly installed at the bottom of the inner buckle plate. The compression head and the sealing gasket correspond to each other to increase the sealing performance of the inner cavity of the connecting cover.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention involves applying a uniform layer of waterproof adhesive to the sidewalls of the mating groove and the outer wall of the connecting cover using a glue gun. The mating plates on both sides of the connecting cover are then inserted into the mating grooves created on one side of the two sets of waterproof backing plates. Since the areas where the waterproof adhesive is applied are smooth and dust-free, the waterproof backing plates are guaranteed to be waterproof and sealed after connection. Furthermore, two sets of expansion nuts and mounting bolts installed in the mounting holes further enhance the stability and firmness of the connecting cover after installation. The pressure from the mounting bolts ensures that the connecting cover fits perfectly against the waterproof backing plates, guaranteeing that the waterproof adhesive completely fills the space between the waterproof backing plates and the connecting cover.
[0015] A sealing gasket is inserted into the inner cavity of the connecting cover, and a compression head is fixedly installed at the bottom of the inner buckle plate. The compression head corresponds to the sealing gasket. After the connecting cover is installed, the inner buckle plate can be snapped into the middle of the connecting cover to fill the middle of the connecting cover, so that the connection between the two sets of waterproof backing plates remains flat. As the inner buckle plate is continuously inserted into the inner cavity of the connecting cover, it will compress the sealing gasket in the inner cavity of the connecting cover, ensuring that the two sides of the sealing gasket are completely attached to the inner wall of the connecting cover, further improving the sealing performance of the connecting cover.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-3A joint sealing device for a waterproof backing board includes: a waterproof backing board 1, which has two sides. Each side of the two sets of waterproof backing boards 1 has a mating groove 13 at its top. A joint sealing mechanism is installed within each of the two sets of mating grooves 13. The joint sealing mechanism has a concave center and an edge sealing assembly is installed in the center of the sealing mechanism. The edge sealing assembly is on the same horizontal plane as the side walls of the two sets of waterproof backing boards 1. The joint sealing mechanism includes a connecting cover 2 installed between the two sets of waterproof backing boards 1. The bottom side of the connecting cover 2 is fixedly equipped with a butt plate 21. Multiple sets of equidistantly distributed mounting holes 22 are opened in the middle of the connecting cover 2. A splicing plate 24 is fixedly installed on the top of the connecting cover 2. Two sets of butt grooves 13 correspond to each other on both sides of the connecting cover 2. The two sets of splicing plates 24 are flush with the sides of the two sets of waterproof backing plates 1. The butt plate 21 is made of polystyrene material. Waterproof adhesive is applied to the surfaces of the butt grooves 13 and the butt plate 21, allowing connection between the two sets of waterproof backing plates 1. The waterproof backing plate 1 is composed of two sets of mortar... The waterproof backing board 12 consists of an outer panel 11, two sets of fiberglass mesh, and a set of extruded polystyrene board 12. The two sets of mortar outer panels 11 are distributed on both sides of the waterproof backing board 1. Fiberglass mesh is bonded to the inner side of both sets of mortar outer panels 11. Extruded polystyrene board 12 is bonded between the two sets of fiberglass mesh to ensure the waterproof effect of the waterproof backing board 1. Waterproof adhesive is applied evenly to the sidewalls of the mating groove 13 and the outer wall of the connecting cover 2 using a caulking gun. The mating plates 21 on both sides of the connecting cover 2 are then inserted into the openings on one side of the two sets of waterproof backing boards 1. Inside the docking groove 13, since the areas where the waterproof adhesive is applied are all smooth and dust-free, the waterproof backing plates 1 can be guaranteed to be waterproof and sealed after connection. In addition, with the corresponding two sets of expansion nuts and the mounting bolts 23 installed in the mounting holes 22, as the mounting bolts 23 continuously squeeze the connecting cover 2, not only is the stability and firmness of the connecting cover 2 after installation further increased, but the pressure on the connecting cover 2 can also perfectly fit with the waterproof backing plate 1, ensuring that the waterproof adhesive fills the space between the waterproof backing plate 1 and the connecting cover 2.
[0022] Furthermore, the edge sealing assembly includes slots 32 on both sides of the inner cavity of the connecting cover 2, an inner buckle plate 3 inserted into the inner cavity of the connecting cover 2, and clips 31 fixedly installed on both sides of the inner buckle plate 3. The two sets of clips 31 correspond to the two sets of slots 32 respectively. The inner buckle plate 3 has a T-shaped cross-section and can seal the edge of the joint sealing mechanism. A sealing gasket 33 is inserted into the inner cavity of the connecting cover 2, and a pressing head 34 is fixedly installed at the bottom of the inner buckle plate 3. The pressing head 34 corresponds to the sealing gasket 33. After the connecting cover 2 is installed, the inner buckle plate 3 can be snapped into the middle of the connecting cover 2 to fill the middle of the connecting cover 2, so that the connection of the two sets of waterproof backing plates 1 remains flat. As the inner buckle plate 3 is continuously inserted into the middle inner cavity of the connecting cover 2, it will squeeze the sealing gasket 33 in the inner cavity of the connecting cover 2, ensuring that the two sides of the sealing gasket 33 are completely attached to the inner wall of the connecting cover 2, further improving the sealing performance of the connecting cover 2.
[0023] Furthermore, a sealing gasket 33 is inserted into the inner cavity of the connecting cover 2, and a compression head 34 is fixedly installed at the bottom of the inner buckle plate 3. The compression head 34 corresponds to the sealing gasket 33, which increases the sealing performance of the inner cavity of the connecting cover 2. By installing the sealing gasket 33 in the inner cavity of the connecting cover 2 and compressing the sealing gasket 33 with the compression head 34 installed in the middle of the inner buckle plate 3, it can be ensured that both sides of the sealing gasket 33 are completely attached to the inner wall of the connecting cover 2, which further improves the sealing performance of the connecting cover 2.
[0024] Furthermore, multiple sets of equidistant expansion nuts are installed on the wall between the two sets of waterproof backing plates 1. Two sets of expansion nuts and mounting holes 22 are fitted with mounting bolts 23 to correspond to each other. By installing expansion nuts on the wall between the two sets of waterproof backing plates 1 and installing bolts in the corresponding expansion nuts and mounting holes 22, the connecting cover 2 can be fixed between the two sets of waterproof backing plates 1.
[0025] In use, when splicing and installing the two sets of waterproof backing boards 1, a cutting machine can be used to cut a butt joint groove 13 on the adjacent side of the two sets of waterproof backing boards 1, exposing the polystyrene extruded board 12 inside the two sets of waterproof backing boards 1. At the same time, a glue gun is used to apply a uniform waterproof adhesive to the side wall of the butt joint groove 13 and the outer wall of the connecting cover 2. Wait for the butt joint plates 21 on both sides of the connecting cover 2 to be inserted into the butt joint groove 13 opened on one side of the two sets of waterproof backing boards 1. Since the areas where the waterproof adhesive is applied are smooth and dust-free, the waterproofing and sealing of the two sets of waterproof backing boards 1 can be guaranteed after connection. Then, with the corresponding two sets of expansion nuts and the mounting bolts 23 installed in the mounting holes 22, as the mounting bolts 23 continuously compress the connecting cover 2, it not only further increases the waterproofing but also... The connecting cover 2 is stable and secure after installation. Under pressure, the connecting cover 2 can perfectly fit with the waterproof backing plate 1, ensuring that the waterproof adhesive fills the space between the waterproof backing plate 1 and the connecting cover 2. At the same time, a sealing gasket 33 is inserted into the inner cavity of the connecting cover 2, and a compression head 34 is fixedly installed at the bottom of the inner buckle plate 3. The compression head 34 corresponds to the sealing gasket 33. After the connecting cover 2 is installed, the inner buckle plate 3 can be snapped into the middle of the connecting cover 2 to fill the middle of the connecting cover 2, keeping the connection between the two sets of waterproof backing plates 1 flat. As the inner buckle plate 3 is continuously inserted into the middle inner cavity of the connecting cover 2, it will compress the sealing gasket 33 in the inner cavity of the connecting cover 2, ensuring that the two sides of the sealing gasket 33 are completely attached to the inner wall of the connecting cover 2, further improving the sealing performance of the connecting cover 2.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
