Description

Technical Field

[0001] This utility model relates to the field of waterproofing technology for tie bolt holes, specifically a waterproofing structure for tie bolt holes in external walls. Background Technology

[0002] In construction projects, shear walls above ground level are generally constructed using a formwork support system. The formwork support system includes formwork, timber, steel pipes, PVC sleeves, tie bolts, bolt clips, and nuts. After the shear wall concrete is poured and reaches a certain strength, the formwork support is removed, the tie bolts are pulled out, and a tie bolt hole is formed at the tie bolt location.

[0003] Typically, bolt holes are sealed with mortar before plastering the exterior wall, or with expanding foam in the middle and mortar at the outer and inner ends of the bolt holes. However, this method of sealing tie bolt holes is not airtight. Over time, microscopic gaps that cannot be completely closed form between the tie bolt holes and the sealing mortar. Over the years, this can easily lead to serious problems such as exterior wall leakage, dampness on the exterior wall surface, detachment of wall insulation, efflorescence and sandblasting on the stone paint exterior wall, and dampness and water seepage on the interior wall surface. These issues severely affect the functionality of the building's exterior walls and the aesthetics of the building facade. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof structure for tie bolt holes in external walls to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes plugs installed at both ends of a wall bolt hole, wherein the two ends of the wall bolt hole are provided with a funnel-shaped groove, and a connecting groove is provided at the connection point between the funnel-shaped groove and the wall bolt hole. The plugs are inserted into the wall bolt hole, and expanding foam is filled in the wall bolt hole between the plugs. Waterproof mortar is filled in the funnel-shaped groove, and the outer side of the wall bolt hole is inclined downwards, with a waterproof coating provided at the outer opening.

[0006] Preferably, the connecting grooves on the inner and outer sides are circular and square structures, respectively, and a circular plate and a square block are respectively installed thereon. The end of the plug that is furthest away from the plug is fixed to the square block and the circular plate, respectively.

[0007] Preferably, an internal threaded sleeve is fixed at the center of the inner side of the square block, the internal threaded sleeve passes through the plug and is fixedly connected to the plug, and a threaded rod is fixed on the inner side of the circular plate, the end of the threaded rod passes through the plug and is threadedly connected to the internal threaded sleeve.

[0008] Preferably, a central groove is provided at the center of the outer side of the circular plate, and a horizontal plate is fixed in the central groove.

[0009] Preferably, the inner sides of the circular plate and the square block abut against the sidewall of the connecting groove and are fixed with sealing gaskets.

[0010] Preferably, a sealing ring is fixed to the outside of the plug.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the waterproof sealing structure for tie bolt holes is easy to construct and has strong applicability; the tie bolt holes are inclined from the inside to the outside, making it difficult for water to flow back and providing good water blocking effect; and the multi-layer sealing structure increases the sealing performance of the hole groove and improves the overall sealing effect.

[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] Please see Figure 1-3 This utility model provides a technical solution: including plugs 6 installed at both ends of a bolt hole 1 in a wall, a funnel-shaped groove 2 provided at both ends of the bolt hole 1, a connecting groove 3 provided at the connection between the inner side of the funnel-shaped groove 2 and the bolt hole 1 in the wall, the plugs 6 being inserted into the bolt hole 1, the bolt hole 1 in the wall and between the plugs 6 being filled with expanding foam, the funnel-shaped groove 2 being filled with waterproof mortar 5, the outer side of the bolt hole 1 being inclined downward, and a waterproof coating 4 being provided at the outer opening, and a sealing ring 61 being fixed to the outer side of the plugs 6.

[0018] The inner and outer connecting grooves 3 are circular and square structures, respectively, and a circular plate 8 and a square block 7 are installed on them. The end of the plug 6 is fixed to the square block 7 and the circular plate 8 respectively. An internal threaded sleeve 62 is fixed at the center of the inner side of the square block 7. The internal threaded sleeve 62 passes through the plug 6 and is fixedly connected to the plug 6. A threaded rod 63 is fixed on the inner side of the circular plate 8. The end of the threaded rod 63 passes through the plug 6 and is threadedly connected to the internal threaded sleeve 62. A central groove 81 is opened at the center of the outer side of the circular plate 8. A horizontal plate 82 is fixed in the central groove 81. The inner sides of the circular plate 8 and the square block 7 abut against the side wall of the connecting groove 3 and are fixed with a sealing gasket 9.

[0019] Working principle: When fixing the formwork for the external wall casting, the bolts and sleeves need to be set outwards at an angle. After the wall is formed, outwardly angled wall bolt holes 1 are formed. At this time, a funnel-shaped groove 2 is chiseled at both ends of the wall bolt hole 1, and a connecting groove 3 is opened on the inner wall of the funnel-shaped groove 2. The dimensions of the inner and outer connecting grooves 3 are adapted to the dimensions of the circular plate 8 and the square block 7, respectively. Then, the square block 7 is inserted into the outer connecting groove 3, so that the internal threaded sleeve 62 enters the wall bolt hole 1. Then, foam is filled into the wall bolt hole 1. When the foaming agent is fully loaded and not yet cured, it is tightened into the inner threaded sleeve 62 using the threaded rod 63, which ultimately ensures that the circular plate 8 and the square block 7 are both fixed in the connecting groove 3. Therefore, the plug 6 can be inserted into both ends of the wall bolt hole 1 to ensure that the foaming agent is more fully filled in the wall bolt hole 1. The openings at both ends are sealed twice by the plug 6, the square block 7 and the circular plate 8. Finally, the hopper-shaped groove 2 is filled with waterproof mortar 5, and after the waterproof mortar 5 on the outside is cured, a waterproof coating 4 is applied to its surface to further reduce the risk of water seepage.
