Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically to a wall screw hole sealing device. Background Art

[0002] When pouring concrete walls in construction projects, it is necessary to set up the formwork first. Since the formwork alone cannot withstand the lateral pressure generated by the pouring of concrete, it is necessary to install through-wall screws for reinforcement. The through-wall screws are metal rods with threads at both ends. The length is determined by the thickness of the wall and is slightly longer. The construction workers drill holes in the assembled formwork at reasonable intervals and insert the through-wall screws. The two ends of the screws pass through the outside of the formwork for easy installation of reinforcement accessories. When removing the formwork, the two ends need to be sawed off, and the sawing position is located inside the wall. Then, grouting is performed to seal these holes. The grouting and sealing operation is relatively complicated. It is necessary to first prepare suitable grouting materials, such as cement mortar, special grouting agents, etc., prepare corresponding grouting equipment, such as grouting pumps, etc., and then insert the grouting pipe into the hole for grouting. The whole process has many steps and takes a long time, especially in large-scale wall screw hole sealing operations, which will significantly slow down the construction progress.

[0021] Specifically, a wall screw hole sealing device includes a push rod 1, an inner wall of the push rod 1 is provided with card grooves 2 at equal intervals, the end face of the push rod 1 is fixedly connected with a fixing plate 3, a through groove 31 is provided at the inner center of the fixing plate 3, an elastic tube 4 is fitted on the surface of the fixing plate 3, a positioning rod 5 is inserted into the interior of the push rod 1, a positioning block 6 is slidably connected to the interior of the positioning rod 5, the end face of the positioning rod 5 is fixedly connected with a push rod 7, the end face of the push rod 7 is fixedly connected with a push tube 8, the end face of the push tube 8 is fixedly connected with a connecting rod 9, the end face of the connecting rod 9 is fixedly connected with a disc 10, the surface of the positioning block 6 is fixedly connected with a sliding plate 61, and the surface of the sliding plate 61 is fixedly installed with a return spring 62.

[0022] In the present embodiment, by providing a resist rod 1, a fixing plate 3 and an elastic tube 4, etc., after the resist rod 1, the elastic tube 4 and the resist tube 8 are placed into the wall hole, the disc 10 is struck, and due to the squeezing of the resist tube 8 and the elastic tube 4, the elastic tube 4 can be deformed, the outer diameter of the elastic tube 4 is expanded, and the outer surface of the elastic tube 4 is tightly pressed against the inner wall of the wall hole, so that the inside of the wall hole can be quickly sealed. This efficient method can significantly speed up the overall construction progress, effectively avoid affecting the subsequent processes due to delays in the wall hole sealing work, and ensure that the entire project proceeds smoothly as planned.

[0023] Specifically, a limiting groove 11 is provided inside the fixed plate 3, and the limiting groove 11 is slidably connected to the limiting plate 12. An insertion rod 13 is fixedly connected to the inner center of the limiting plate 12, and a tension spring 14 is fixedly connected to the surface of the limiting plate 12. The surface of the push rod 7 close to the positioning rod 5 is conical, and the end face of the insertion rod 13 close to the through groove 31 rests on the surface of the push rod 7.

[0024] In this embodiment, by providing a slidable plug rod 13, when the striking disc 10 blocks the inside of the wall hole, the plug rod 13 will slide in the direction away from the through groove 31, and the conical surface of the plug rod 13 will abut against the inner wall of the wall hole, which can enhance the stability of the entire device inside the wall hole, ensure that the device is firmly fixed at a preset position in the wall hole, avoid the device from gradually loosening or even detaching from the wall hole due to factors such as vibration generated by the operation of the equipment and external force impact, and ensure the long-term reliability of the installation.

[0025] Specifically, the surface of the resisting tube 8 close to the resisting rod 7 is conical, the diameter of the resisting tube 8 is larger than the inner diameter of the elastic tube 4 , and the surface of the resisting tube 8 abuts against the inner wall of the elastic tube 4 .

[0026] In this embodiment, due to the shape of the abutment tube 8 , the elastic tube 4 can be deformed through the friction between the abutment tube 8 and the elastic tube 4 .

[0027] Specifically, the surface of the positioning block 6 is arc-shaped, and the outer surface of the sliding plate 61 is slidably connected to the inside of the positioning rod 5. Under normal circumstances, the surface of the positioning block 6 is clamped in the inside of the slot 2 through the elasticity of the return spring 62.

[0028] In this embodiment, the sliding movement of the positioning rod 5 can be positioned by the engagement between the positioning block 6 and the locking slot 2 .

[0029] Specifically, the elastic tube 4 is a silicone tube, the end surface of the abutting rod 1 abuts against the bottom of the wall hole, and the diameter of the elastic tube 4 is smaller than the diameter of the wall hole.

[0030] In this embodiment, since the elastic tube 4 is a silicone tube, its surface can be closely attached to the inside of the wall hole, which can enhance the sealing of the connection.

[0031] Specifically, the end surface of the insertion rod 13 extends into the inside of the through slot 31 , the end of the insertion rod 13 close to the through slot 31 is arc-shaped, and the end of the insertion rod 13 away from the through slot 31 is conical.

[0032] In this embodiment, since the end of the insertion rod 13 close to the through groove 31 is arc-shaped, the friction between the insertion rod 13 and the stop rod 7 can be reduced.

[0033] The working principle and use process of the utility model are as follows: when in use, the elastic tube 4 is sleeved between the stop rod 7 and the stop tube 8, and then the positioning rod 5 is inserted into the inside of the stop rod 1, and the surface of the positioning block 6 is clamped in the inside of the clamping groove 2 near the direction of the through groove 31 inside the stop rod 1, and then the whole is inserted into the wall hole. At this time, the disc 10 is located outside the wall hole, and then the disc 10 is hit by a hammer. At this time, the disc 10 slides to the left through the connecting rod 9, the stop tube 8, the stop rod 7 and the positioning rod 5, so that the positioning block 6 is clamped in the inside of the clamping groove 2 deep inside the stop rod 1. Due to the abutment between the stop rod 1 and the deep inside of the wall hole, the position of the elastic tube 4 remains unchanged. Therefore, when the stop tube 8 slides to the left, the friction between the stop tube 8 and the inner wall of the elastic tube 4 can cause the elastic tube 4 to deform, so that the elastic tube 4 The outer diameter of the wall hole is enlarged, and the outer surface of the elastic tube 4 is tightly pressed against the inner wall of the wall hole, so that the inside of the wall hole can be quickly sealed. This efficient method can significantly speed up the overall construction progress, effectively avoid affecting the subsequent process due to the delay of the wall hole sealing work, and ensure that the entire project is smoothly carried out as planned. When the hammering disc 10 seals the inside of the wall hole, the friction between the surface of the push rod 7 and the end face of the insertion rod 13 can make the insertion rod 13 slide away from the groove 31, and make the tapered surface of the insertion rod 13 press against the inner wall of the wall hole, which can enhance the stability of the entire device inside the wall hole, ensure that the device is firmly fixed at the preset position in the wall hole, avoid the vibration generated by the operation of the equipment, external force impact and other factors that cause the device to gradually loosen or even detach from the wall hole, and ensure the long-term reliability of the installation.
