Description

Technical Field

[0001] This utility model belongs to the field of stone decoration technology, and in particular relates to a back bolt fixing structure for preventing efflorescence on stone decorative walls. Background Technology

[0002] Efflorescence is essentially caused by moisture carrying soluble salts (such as Ca(OH)2) from the material to the surface, forming white crystals after drying. Efflorescence is a common quality problem in stone decoration (such as curtain walls, floors, and walls), which not only affects aesthetics but may also damage the stone structure in the long run. Therefore, we designed an anti-efflorescence back-bolt fixing structure for stone decorative walls. The space between the back bolt and the stone is filled with neutral weather-resistant adhesive, and a sealing gasket covers the holes to prevent moisture from entering the installation holes through the back bolt, effectively preventing efflorescence. Utility Model Content

[0003] The purpose of this utility model is to provide a back-bolt fixing structure for preventing efflorescence on stone decorative walls. It features a neutral weather-resistant adhesive filling the space between the back-bolt and the stone, and a sealing gasket covering the holes to prevent moisture from entering the installation holes through the back-bolt, thus effectively preventing efflorescence and solving the aforementioned technical problems.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a back bolt fixing structure for preventing efflorescence on stone decorative walls, comprising an installation hole opened in the stone, a top rod inserted into the inner cavity of the installation hole, a frustum head at the end of the top rod that is inserted deep into the inner cavity of the installation hole, a ring sleeved on the surface of the top rod, a deformable tooth with an annular array distributed on one side of the ring, a slidable abutment sleeved on the surface of the top rod, the inner cavity of the installation hole filled with neutral waterproof sealant, the abutment sleeve located in the inner cavity of the installation hole, a neutral silicone weather-resistant sealant extending to the outside of the installation hole filling the space between the abutment sleeve and the top rod, and a sealing gasket abutting against the stone sleeved on the surface of the top rod.

[0005] Preferably, the surface of the top rod is fitted with a hanging profile, and one side of the hanging profile abuts against one side of the sealing gasket.

[0006] Preferably, one end of the top rod extends through the hanging profile and is fitted with a washer and a nut, the nut being threaded onto the surface of the top rod.

[0007] Preferably, an adjusting bolt is provided through the top of the hanging profile, and the adjusting bolt is threadedly connected to the hanging profile.

[0008] Preferably, the sealing gasket has an opening near the top rod with a recess that is fitted onto a neutral silicone weather-resistant adhesive.

[0009] The beneficial effects of this utility model are:

[0010] 1. This utility model pre-fills the installation hole with neutral waterproof sealant, then inserts the conical head of the top rod into the inner cavity of the installation hole. Next, the movement of the abutment tube drives the ring to move, causing multiple deformation teeth to expand outward and support the deep inner cavity of the installation hole. Then, neutral silicone weather-resistant sealant is filled at the connection between the top rod and the abutment tube, and a sealing gasket is put on the surface of the top rod to cover the installation hole. This multiple barrier prevents moisture from entering the installation hole. Thus, the neutral weather-resistant sealant between the back bolt and the stone, combined with the sealing gasket covering the hole, effectively prevents moisture from entering the installation hole through the back bolt, thus achieving the purpose of preventing efflorescence.

[0011] 2. By designing a concave cavity, this utility model ensures that when the sealing gasket is in contact with the stone, the concave cavity on the sealing gasket will cover the neutral silicone weather-resistant adhesive, effectively preventing the sealing gasket from lifting and ensuring the sealing effect at the contact point between the sealing gasket and the stone.

[0018] In the following description, embodiments of the anti-efflorescence back bolt fixing structure for stone decorative walls of this utility model will be described with reference to the accompanying drawings.

[0019] Figure 1-3This invention illustrates an embodiment of a back-bolt fixing structure for preventing efflorescence on a stone decorative wall surface. It includes an installation hole 1 formed in the stone, a top rod 2 inserted into the inner cavity of the installation hole 1, a frustum-shaped head 3 at the end of the top rod 2 that extends deep into the inner cavity of the installation hole 1, a ring 4 fitted onto the surface of the top rod 2, and a ring-shaped array of deformable teeth 5 on one side of the ring 4. A slidable abutment tube 6 is fitted onto the surface of the top rod 2. The inner cavity of the installation hole 1 is filled with neutral waterproof sealant 7. A sealing gasket 9 has a recess 13 near the top rod 2, fitted onto a neutral silicone weather-resistant sealant 8. The recess 13 allows the sealing gasket 9 to cover the stone surface when in contact with the stone. 3 covers the neutral silicone weather-resistant sealant 8, effectively preventing the sealing gasket 9 from lifting and ensuring the sealing effect of the sealing gasket 9 in contact with the stone. The abutment tube 6 is located in the inner cavity of the installation hole 1. The space between the abutment tube 6 and the top rod 2 is filled with neutral silicone weather-resistant sealant 8 extending to the outside of the installation hole 1. The surface of the top rod 2 is fitted with a sealing gasket 9 that abuts against the stone. The surface of the top rod 2 is fitted with a hanging profile 10. One side of the hanging profile 10 abuts against one side of the sealing gasket 9. One end of the top rod 2 passes through the hanging profile 10 and is fitted with a gasket 11 and a nut 12. The nut 12 is threadedly connected to the surface of the top rod 2. An adjusting bolt is provided through the top of the hanging profile 10 and is threadedly connected to the hanging profile 10.

[0020] Working principle: When using this utility model, neutral waterproof sealant 7 is pre-filled into the mounting hole 1. Then, the conical head 3 at the end of the top rod 2 is inserted into the inner cavity of the mounting hole 1. Then, the movement of the abutment tube 6 drives the ring 4 to move, so that multiple deformation teeth 5 expand outward due to the inclined surface of the conical head 3 and are supported deep in the inner cavity of the mounting hole 1. During this process, the neutral waterproof sealant 7, being a fluid, will overflow to the outside of the mounting hole 1. The overflowing neutral waterproof sealant 7 is cleaned up. Then, neutral silicone weather-resistant sealant 8 is filled at the connection between the top rod 2 and the outside of the abutment tube 6, and a sealing gasket 9 is put on the surface of the top rod 2. The concave cavity 13 on the sealing gasket 9 is covered with neutral silicone weather-resistant sealant 8 and covers the mounting hole 1, thus preventing moisture from entering the mounting hole 1.

[0021] In summary, this anti-efflorescence back-bolt fixing structure for stone decorative walls works by first filling the installation hole 1 with neutral waterproof sealant 7, then inserting the conical head 3 at the end of the top rod 2 into the inner cavity of the installation hole 1. Next, the movement of the abutment tube 6 moves the ring 4, causing multiple deformation teeth 5 to expand outwards and support the interior of the installation hole 1. Then, neutral silicone weather-resistant sealant 8 is filled at the connection between the top rod 2 and the abutment tube 6, and a sealing gasket 9 is placed on the surface of the top rod 2 to cover the installation hole 1. This multi-layered isolation prevents moisture from entering the installation hole 1. By filling the space between the back bolt and the stone with neutral weather-resistant sealant, and using the sealing gasket to cover the hole, moisture is prevented from entering the installation hole through the back bolt, effectively achieving the anti-efflorescence function.
