Technical Field
[0001] The invention discloses an external wall bolt hole blocking structure, which is used for blocking the external wall bolt hole and belongs to the technical field of blocking structures. Background Art
[0002] External wall bolt hole sealing is a construction technology used to seal and fix bolt holes that pass through the wall when installing or fixing external facilities (such as curtain walls, brackets, pipes, etc.) on the exterior wall of a building. The key to this technology is to ensure the sealing performance of the bolt holes to prevent moisture, air and impurities from entering the interior of the wall, thereby improving the waterproof, thermal insulation and durability of the wall.
[0003] The steps for plugging bolt holes on exterior walls are as follows: first, determine the location, size, and depth of the bolt holes on the wall according to the design requirements, and use professional tools to drill the holes. After drilling, clean the dust and impurities in the holes to ensure that the holes are clean and dry. Install plugging parts in the bolt holes.
[0004] However, the external wall bolt hole blocking structure in the prior art has the following technical problems:
[0005] 1. Poor sealing, which may cause leakage or reduced thermal insulation performance;
[0006] 2. Poor durability, will age, harden or shrink over time, resulting in reduced sealing performance and the need for regular maintenance;
[0007] 3. Unable to bear the weight of external facilities or wind load, which may easily cause structural safety problems. Utility Model Content

[0011] Further, the reinforcing seal comprises an upper disc and a lower disc, a connecting piece arranged between the upper disc and the lower disc, and a speaker stopper arranged on the upper disc and an injection hole for injecting a foaming agent into between the upper disc and the lower disc;
[0012] The upper disc and the lower disc are respectively provided with sealing rings.
[0013] Further, the connecting member includes an inner reinforcement member and an outer reinforcement member which are arranged at equal intervals along the circumference direction of the upper disk and the lower disk on the side close to the center of the circle and on the side close to the edge;

[0039] Example 1
[0040] In order to solve the problems of poor sealing performance of the existing technology, which may easily cause leakage or decrease in thermal insulation performance. Figure 1-4 As shown, a bolt hole sealing structure for an exterior wall is provided, comprising a reinforcing seal 1 inserted into the bolt hole, a foaming agent 2 filled between the reinforcing seal 1 and the bolt hole wall, an expansive cement mortar 3 for sealing the bolt holes at both ends of the reinforcing seal 1, and a waterproof layer applied to the bolt holes after sealing on the outside of the exterior wall.
[0041] In practice, the bolt hole on the outer side of the exterior wall is expanded into a trumpet shape and cleaned. After cleaning, the reinforcing seal 1 is inserted into the bolt hole from one end of the trumpet shape, and the bolt hole at the opposite end of the trumpet shape is filled with expansion cement mortar. After the expansion cement mortar solidifies, the foaming agent 2 is injected between the reinforcing seal 1 and the bolt hole wall, and then the expansion cement mortar is filled into the bolt hole at one end of the trumpet shape. After the expansion cement mortar solidifies, a waterproof layer is applied on and around it. In practice, the installation method can also be selected and applied according to practical needs. In this embodiment, by inserting the reinforced seal into the bolt hole and injecting a foaming agent between the reinforced seal and the bolt hole, the gap in the bolt hole can be effectively filled, the sealing performance can be improved, and moisture and air penetration can be prevented, thereby achieving the effect of anti-leakage and heat insulation, and the expanded cement mortar and the waterproof layer can further enhance the waterproof effect and protect the wall from moisture. By filling the bolt hole with the reinforced seal, the foaming agent and the expanded cement mortar, the reinforced seal and the threaded hole can be closely matched, so that it has good durability and can withstand the weight of external facilities or wind loads, thereby improving the safety of the structure.
[0042] Example 2
[0043] On the basis of Example 1, the reinforced seal 1 comprises an upper disc 4 and a lower disc 5, a connecting member 6 arranged between the upper disc 4 and the lower disc 5, a horn stopper 7 arranged on the upper disc 4 and an injection hole 8 for injecting a foaming agent between the upper disc 4 and the lower disc 5; the upper disc 4 and the lower disc 5 are respectively provided with a sealing ring 9. In practice, after the reinforced seal 1 is inserted into the bolt hole, the horn stopper 7 can be matched with the horn mouth of the bolt hole for limiting positioning, and the foaming agent can be injected between the upper disc 4 and the lower disc 5 through the injection hole 8, so that the foaming agent wraps the connecting member and is fixed in the bolt hole as a whole. The connecting member in this embodiment fixes the upper disc and the lower disc together and accurately positions the reinforced seal in the bolt hole through the horn stopper, which not only ensures the accuracy of the blocking position, but also forms a stable structure, so that the reinforced seal can evenly withstand pressure in the bolt hole, improving the overall stability of the blocking structure, and the sealing rings are provided on the upper disc and the lower disc to provide a double sealing effect, further improving the sealing performance.
[0044] Example 3
[0045] On the basis of Example 2, the connector 6 includes an inner reinforcement 10 and an outer reinforcement 11 arranged at equal intervals along the circumference direction of the upper disk 4 and the lower disk 5, which are close to the center of the circle and close to the edge of the circle; the inner reinforcement 10 and the outer reinforcement 11 include a plurality of reinforcing rods 12 arranged at equal intervals, and the foaming agent will fill the space between the reinforcing rods 12 and between the reinforcing rods and the inner wall of the bolt hole after injection. By arranging the inner reinforcement and the outer reinforcement at equal intervals along the circumference direction of the upper disk and the lower disk, the stability of the overall structure can be enhanced, the ability of the connector to bear external loads can be improved, the deformation or damage of the structure caused by external forces can be reduced, and it is conducive to forming an integral body with the foaming agent. Of course, in practice, it is not ruled out that the connector can also adopt other structures.
[0046] Example 4
[0047] On the basis of Example 3, the edge sides of the upper disc 4 and the lower disc 5 are respectively provided with an annular T-shaped limiting groove 13, and the sealing ring 9 is a T-shaped sealing ring clamped in the annular T-shaped limiting groove 13. The T-shaped sealing ring is clamped in the T-shaped limiting groove, which can avoid the displacement of the T-shaped sealing ring due to friction when the reinforced sealing member is inserted into the bolt hole, so as to provide reliable sealing performance. After the reinforced sealing member is installed in place, it can effectively prevent fluid or gas leakage. At the same time, it is also convenient to replace sealing rings of different sizes according to sealing requirements.
[0048] Example 5
[0049] On the basis of Example 4, the lower disc 5 is provided with a groove 14 on the opposite side connected to the connecting member 6, and a plurality of through holes A15 are provided on the side wall of the groove 14; and a plurality of through holes B16 are provided on the horn stopper 7. The expansion cement mortar 3 will enter the groove, the horn stopper 7, the through holes A15 and B16, and between the groove and the bolt hole, and between the horn stopper 7 and the bolt hole. Therefore, the groove is provided, the through hole A is provided on the groove, and the through hole B is provided on the horn stopper, so as to facilitate the expansion cement mortar to be firmly fixed in the bolt hole as a whole.
[0050] Example 6
[0051] On the basis of Example 5, the injection hole 8 is arranged at the center of the upper disk 4. By limiting the location of the injection hole 8, it is possible to effectively avoid the problem of the location of the injection hole when installing the reinforcing seal 1. For example, when the injection hole is on one side of the edge, the injection hole needs to be installed on the upper end to avoid the injected foaming agent from flowing back easily.
