Description

Technical Field

[0001] The utility model relates to the technical field of wall back-embedded parts, in particular to a waterproof device for a wall back-embedded part node. Background Art

[0002] Wall embedded parts can be divided into pre-embedded parts and post-embedded parts. Pre-embedded parts refer to connecting parts embedded in the wall during construction. Post-embedded parts are non-prefabricated embedded parts that are fixed in designated positions after construction is completed, but must be drilled in the building before installation. They are usually used for exterior decoration such as curtain wall projects; post-embedded parts refer to connecting parts installed on existing wall structures through relevant technical means.

[0003] In actual construction, the renovation, decoration, electrical installation or temporary construction of existing buildings all require embedded parts behind the wall to complete the connection. The most commonly used embedded parts behind the wall are expansion bolts. After the expansion bolts are installed in the wall, steel plates are generally required to be installed. When installing expansion bolts on some exterior walls or other walls that require waterproofing, their waterproof coating is often damaged, which makes it easy for water to seep in over time, reducing the strength and life of the wall.

[0004] The existing technology generally adopts the method of applying sealant around the steel plate. There is a risk of debonding of the sealant, and disassembly can easily cause secondary damage to the wall waterproof layer. In addition, a separate waterproof device for full coverage of the node often forms a large installation gap. Therefore, there is an urgent need for a wall-embedded node waterproof device that is simple to install, practical and reliable. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a waterproof device for a node of a wall-mounted embedded part.

[0006] The specific technical solutions provided by this utility model are as follows:

[0007] The utility model provides a waterproof device for a wall post-embedded node, comprising a wall provided with a waterproof layer and a mounting plate, wherein a main screw and a positioning screw are fixed to the wall by post-anchor bolts, and the mounting plate is sleeved on the main screw and the positioning screw. The improvement lies in that a rubber pad is installed between the wall and the mounting plate, a pressure plate is sleeved on the side of the mounting plate away from the wall, the pressure plate comprises a main pressure ring sleeved on the main screw, the circumferential side of the main pressure ring is connected to a fixed pressure ring by a connecting pressure rod, and the fixed pressure ring is pressed onto the mounting plate by a nut.

[0008] By adopting the above technical solution, the fixed pressure ring of the pressure plate is pressed against the mounting plate by a nut, thereby fixing the mounting plate and the rubber pad to the wall; at the same time, the fixed pressure ring drives the main pressure ring to press the mounting plate around the main screw through the connecting pressure rod. The entire mounting plate is subjected to force at multiple points, which can reduce the installation gap and improve the fit with the rubber pad, thereby improving the installation and sealing effect.

[0009] Furthermore, the rubber pad includes a mounting plate sealing ring for sealing the mounting plate and a gasket sleeved on the main screw. Two transverse sealing strips and two longitudinal sealing strips are provided inside the mounting plate sealing ring, and a positioning screw sealing ring is provided at the intersection of the transverse sealing strips and the longitudinal sealing strips.

[0010] Using the above technical solution, the mounting plate sealing ring is used for the first seal on the peripheral side of the mounting plate. The two transverse sealing strips and the two longitudinal sealing strips serve to connect the positioning screw sealing ring while jointly forming the second seal. The function of the gasket is not only to support the mounting plate and prevent the center of the mounting plate from collapsing under force, but also to seal the main screw.

[0011] Furthermore, the positioning screw seal ring is interference fit with the positioning screw.

[0012] The above technical solution is used to position the axial seal of the screw 3.

[0013] Furthermore, a gasket groove is provided on one side of the main pressure ring close to the mounting plate, and a main screw sealing ring is provided in the gasket groove.

[0014] Furthermore, the gasket is fixed on the transverse sealing strip or the longitudinal sealing strip.

[0015] Furthermore, the main screw sealing ring is interference fit with the main screw, the thickness of the main screw sealing ring is greater than the depth of the gasket groove, and the outer diameter of the main screw sealing ring is smaller than the inner diameter of the gasket groove.

[0016] The above technical solution ensures that the sealing ring can extend out of the gasket groove during installation, and that there is space for expansion on the compressed side after installation.

[0017] Furthermore, the mounting plate is provided with a main screw mounting hole for mounting the main screw and a positioning screw mounting hole for mounting the positioning screw.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] The utility model adopts a pressure plate to make the installation plate bear force at multiple points, reducing the installation gap and improving the fit with the rubber pad; the rubber pad with an integrated structure is used for multi-pass sealing, which is more reliable and will not damage the wall again.

[0026] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that the post-anchor bolt fixation in the present invention is a wall bolt installation method. The more common method is to install expansion bolts after punching holes in the wall, so it will destroy the waterproof layer of the wall. Therefore, the position that needs to be sealed is the installation position of the main screw 2 and the positioning screw 3 on the wall.

[0027] like Figures 1 to 4As shown, the utility model provides a wall post-embedded node waterproof device, including a wall 1 provided with a waterproof layer and a mounting plate 4, a main screw 2 and a positioning screw 3 are fixed to the wall 1 by post-anchor bolts, and the mounting plate 4 is sleeved on the main screw 2 and the positioning screw 3. Specifically, a rubber pad 5 is installed between the wall 1 and the mounting plate 4, and a pressure plate 6 is sleeved on the side of the mounting plate 4 away from the wall 1. More specifically, the pressure plate 6 includes a main pressure ring 61 sleeved on the main screw 2, and the main pressure ring 61 is connected to a fixed pressure ring 62 on its circumference by a connecting pressure rod 63, and the fixed pressure ring 62 is pressed tightly on the mounting plate 4 by a nut 7.

[0028] In addition, if Figure 2 As shown, the mounting plate 4 is provided with a main screw mounting hole 42 for mounting the main screw 2 and a positioning screw mounting hole 41 for mounting the positioning screw 3 .

[0029] The principle of the above structure is that when in use, the fixed pressure ring 62 of the pressure plate 6 is pressed against the mounting plate 4 by the nut 7, thereby fixing the mounting plate 4 and the rubber pad 5 on the wall 1; at the same time, the fixed pressure ring 62 drives the main pressure ring 61 to press the mounting plate 4 on the side of the main screw 2 through the connecting pressure rod 63. The entire mounting plate 4 is subjected to force at multiple points, which can reduce the installation gap and improve the fit with the rubber pad 5, thereby improving the installation and sealing effect.

[0030] If the rubber pad 5 is punched with a whole rubber sheet, it will bring the following problems: first, it is a waste of rubber resources, and second, it is damaged at a single point of the rubber pad 5, which will lead to the failure of the overall sealing. Therefore, the rubber pad 5 has been improved as follows.

[0031] like Figure 3 As shown, the rubber pad 5 includes a mounting plate sealing ring 51 for sealing the mounting plate 4 and a gasket 55 sleeved on the main screw 2. Two transverse sealing strips 52 and two longitudinal sealing strips 53 are provided inside the mounting plate sealing ring 51, and a positioning screw sealing ring 54 is provided at the intersection of the transverse sealing strips 52 and the longitudinal sealing strips 53.

[0032] More specifically, the positioning screw seal ring 54 is interference fit with the positioning screw 3 and is used for axial sealing of the positioning screw 3 .

[0033] The principle of the above structure is: the mounting plate sealing ring 51 is used for the first seal on the peripheral side of the mounting plate 4, the two transverse sealing strips 52 and the two longitudinal sealing strips 53 serve to connect the positioning screw sealing ring 54 while jointly constituting the second seal, and the function of the gasket 55 is not only to support the mounting plate 4 and prevent the center of the mounting plate 4 from collapsing due to force, but also to seal the main screw 2.

[0034] like Figure 4As shown, a gasket groove 64 is provided on one side of the main pressure ring 61 close to the mounting plate 4 , and a main screw sealing ring 8 is provided in the gasket groove 64 .

[0035] Specifically, the main screw sealing ring 8 is interference fit with the main screw 2 and is used for axial sealing of the main screw 2; the thickness of the main screw sealing ring 8 is greater than the depth of the gasket groove 64, and the outer diameter of the main screw sealing ring 8 is smaller than the inner diameter of the gasket groove 64; the above structure ensures that the main screw sealing ring 8 can extend out of the gasket groove 64 when installed, and there is space for expansion on the compressed side after installation.

[0036] More specifically, the gasket 55 is fixed on the transverse sealing strip 52 or the longitudinal sealing strip 53 , so that the rubber pad 5 is an integrated structure, which is convenient for storage and installation.

[0037] The working principle of this utility model is as follows:

[0038] When in use, the fixed pressure ring 62 of the pressure plate 6 is pressed against the mounting plate 4 through the nut 7, and then the mounting plate 4 and the rubber pad 5 are fixed to the wall 1; at the same time, the fixed pressure ring 62 drives the main pressure ring 61 to press the mounting plate 4 on the side of the main screw 2 through the connecting pressure rod 63. The entire mounting plate 4 is subjected to force at multiple points, which can reduce the installation gap and improve the fit with the rubber pad 5, thereby improving the installation and sealing effect.

[0039] Among them, the mounting plate sealing ring 51 of the rubber pad 5 is used for the first sealing on the peripheral side of the mounting plate 4. The two transverse sealing strips 52 and the two longitudinal sealing strips 53 serve to connect the positioning screw sealing ring 54 while jointly constituting the second sealing. The function of the gasket 55 is not only to support the mounting plate 4 and prevent the center of the mounting plate 4 from collapsing due to force, but also to seal the main screw 2.

[0040] The positioning screw seal ring 54 is interference-fitted with the positioning screw 3 and is used for axial sealing of the positioning screw 3 .

[0041] Among them, the main screw sealing ring 8 has an interference fit with the main screw 2 and is used for axial sealing of the main screw 2; the thickness of the main screw sealing ring 8 is greater than the depth of the gasket groove 64, and the outer diameter of the main screw sealing ring 8 is smaller than the inner diameter of the gasket groove 64; the above structure ensures that the main screw sealing ring 8 can extend out of the gasket groove 64 when installed, and there is space for expansion on the compressed side after installation.

[0042] Obviously, those skilled in the art may make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the embodiments of the present invention. Thus, if such modifications and variations of the embodiments of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
