[0002] At present, in the field of civil construction engineering, various types of medium and high-rise buildings mostly use frame shear wall structures. Since the shear wall needs to use tension bolts for formwork support and reinforcement, there are a large number of bolt holes on the wall after the formwork is removed. In order to eliminate the risk of wall leakage during use, it is usually required to use foamed cement or expanded cement or foam glue and other materials to fill and seal the bolt holes. Some drawings require that after the bolt holes are sealed, the bolt holes on the outer wall are made into a circle, and the surrounding area is a sloped ash cake, so as to facilitate the application of waterproof coating on the outside. In the current construction method, after filling the bolt holes, a certain thickness of mortar layer is usually pressed on the outside, and then the excess part is manually removed. This method is difficult to control the mortar thickness, the quality of the ash cake forming and the appearance quality of the ash cake; another method is to use a fixed size PVC pipe or steel pipe to cut and press the mortar layer into a circle, and then trim it around into a slope. The process is relatively complicated, and the position of the ash cake cannot be accurately controlled, the thickness of the ash cake is not easy to control, and it is easy to cause waste of mortar.

DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-2 A bolt hole sealing device for an aluminum mold shear wall comprises a round tube 1, an indicating scale is opened on the outside of the round tube 1, a thick rubber pad 2 is arranged inside the round tube 1, a rubber molding block 3 is fixedly connected to the right side surface of the thick rubber pad 2, a push-pull rod 4 extending to the outside of the round tube 1 is fixedly connected to the right side wall of the rubber molding block 3, after the left end of the round tube 1 is filled with mortar, the left end of the round tube 1 is placed opposite to the bolt hole, the rubber molding block 3 and the thick rubber pad 2 can be pushed to move by the push-pull rod 4, the mortar can be pushed out of the round tube 1 and into the bolt hole, and the bolt hole can be filled.

[0028] The right end of the push-pull rod 4 is fixedly connected to the limit plate 5, and the right side surface of the limit plate 5 is fixedly connected to an arc-shaped handle 6. A fixed handle 7 is installed in the middle of the upper and lower surfaces of the circular tube 1, and an anti-slip sleeve 8 is installed on the outside of the fixed handle 7. A telescopic rod 9 corresponding to the limit plate 5 is installed on the right end of the circular tube 1. The setting of the limit plate 5 and the handle 6 makes it more convenient to apply force to the push-pull rod 4. The anti-slip sleeve 8 cooperates with the fixed handle 7 to facilitate the fixation and use of the circular tube 1. At the same time, the telescopic rod 9 will be compressed when it is subjected to the pressure of the limit plate 5. When the telescopic rod 9 is compressed to a certain length, it can support the limit plate 5 to avoid excessive movement of the limit plate 5 and ensure the compaction effect of the mortar.

[0029] After the circular tube 1 is aligned with the bolt hole, mortar can be conveniently poured into the bolt hole. The upper and lower side surfaces of the left end of the circular tube 1 are fixedly connected with a baffle 10. The left side of the baffle 10 is provided with fixed teeth 11. The baffle 10 fits against the wall surface. In combination with the fixed teeth 11 on the baffle 10, the stability of the circular tube 1 during the grouting process can be guaranteed, so that the sealing work can be carried out more stably.

[0030] According to different bolt holes, the amount of mortar for sealing can be adjusted. The right end of the circular tube 1 is externally slidably connected to a moving tube 12 fixedly connected to the telescopic rod 9. The outer wall of the right end of the circular tube 1 is provided with a slide groove 13 corresponding to the moving tube 12. The inside of the slide groove 13 is slidably connected to a slide plate 14 fixedly connected to the inner wall of the moving tube 12. A through hole 15 is provided in the middle of the anti-slip sleeve 8. A toothed plate 16 is slidably connected inside the upper through hole 15. The top of the circular tube 1 is rotatably connected to a driving gear 17 meshing with the toothed plate 16. A transverse guide groove 23 is provided on the top of the circular tube 1. The inside of the guide groove 23 is slidably connected to the bottom of the toothed plate 16. The fixedly connected guide plate 24 can adjust the amount of mortar pushed out from the circular tube 1 according to the size and depth of the bolt hole required. When the driving gear 17 is rotated, the tooth plate 16 can be driven to move. When the tooth plate 16 moves, the moving tube 12 can be driven to slide outside the circular tube 1. During this process, the telescopic rod 9 moves with the moving tube 12. In this way, the position of the telescopic rod 9 can be adjusted. When the limit plate 5 is pushed, the contact position of the limit plate 5 and the telescopic rod 9 can be adjusted, thereby limiting the position of the thick rubber pad 2 and the rubber molding block 3, making it convenient to adjust the amount of mortar pushed out, so that the device can be adapted to the sealing of different bolt holes.

[0031] The telescopic rod 9 can limit the position of the limit plate 5. The telescopic rod 9 includes a mounting tube 18 fixedly connected to the right end of the moving tube 12 and sealed at the left end. A return spring 19 is fixedly connected to the left inner wall of the mounting tube 18. The right end of the return spring 19 is fixedly connected to a moving piston 20 slidably connected to the inner wall of the mounting tube 18. The right side of the moving piston 20 is fixedly connected to a moving rod 21. The right end of the moving rod 21 extends to the outside of the mounting tube 18 and is fixedly connected to a push plate 22. When the limit plate 5 moves to the left, it pushes the push plate 22 and the moving rod 21 to move. In this process, the moving piston 20 compresses the air in the mounting tube 18 and the return spring 19, so that the total length of the telescopic rod 9 is fixed, thereby limiting the position of the limit plate 5.

[0032] Another technical problem to be solved by the present invention is to provide a method for using an aluminum mold shear wall bolt hole plugging device, comprising the following steps:

[0033] A. Cleaning of bolt holes: Chisel the bolt holes of the external wall into bell-shaped holes as required. Pay attention to the depth of chiseling during construction. The depth of chiseling should not be too deep to improve the molding effect of making ash cakes. It can also facilitate the insertion and observation of tools. Then use the fan to clean the bolt holes, clean the garbage and ash in the bolt holes, and then moisten them with water. Then use the foaming agent to seal the inner side of the bolt holes on the inner side of the wall.

[0034] B Preparation: Clean the foaming agent in the bolt hole and clean the foaming agent in the outer bolt hole to 50mm inside the wall surface for later use;

[0035] C Construction: Add a certain amount of mortar to the left end of the circular tube 1, then align the left end of the circular tube 1 with the bolt hole of the external wall, align the push-pull rod 4 with the bolt hole, hold the handle 6 to push the limit plate 5 and the push-pull rod 4, use the push-pull rod 4 to push the rubber forming block 3 and the thick rubber pad 2 to push the mortar, push the waterproof mortar out of the circular tube 1, and press the waterproof mortar into the bolt hole until the bolt hole of the external wall is filled with mortar;

[0036] D. Finishing: Continue to push the limit plate 5 so that the limit plate 5 can squeeze the telescopic rod 9. When the telescopic rod 9 can no longer be shortened, use the handle 6, the limit plate 5 and the push-pull rod 4 to rotate and extrude the mortar to ensure that the mortar is effectively bonded to the wall, and to ensure the molding quality and visual quality of the mortar.

[0037] The beneficial effects of the present invention are as follows: the threaded hole is first cleaned and moistened, so that the bolt hole is cleaner and easier to bond with mortar, so that the bonding between the formed mortar and the wall is more stable;

[0038] When the limit plate 5 moves to the left, it pushes the push plate 22 and the moving rod 21 to move. During this process, the moving piston 20 compresses the air in the mounting tube 18 and the return spring 19, so that the total length of the telescopic rod 9 is fixed, and the position of the limit plate 5 is limited, so that the thickness of the ash cake can be controlled;

[0039] Continue to push the limit plate 5 so that the limit plate 5 can squeeze the telescopic rod 9. When the telescopic rod 9 can no longer be shortened, use the handle 6, the limit plate 5 and the push-pull rod 4 to rotate and extrude the mortar to ensure effective bonding between the mortar and the wall, thereby ensuring the molding quality and visual quality of the mortar.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
