Description

Technical Field

[0001] The utility model relates to the field of building exterior wall equipment, in particular to an exterior wall screw hole blocking structure. Background Art

[0002] In the construction of concrete structures, due to the requirements of formwork reinforcement, it is necessary to insert tension screws before pouring the structural concrete. The tension screws will be removed after the concrete is poured. After removal, many screw holes will remain on and inside the structure. The sealing of the screw holes in the exterior wall is an important part of construction. The main purpose is to prevent leakage of the exterior wall. Usually, workers need to use a mortar gun to inhale the expanding mortar, then embed the grouting end of the mortar gun into the screw hole and inject the expanding mortar for sealing.

[0003] In the existing external wall screw hole sealing structure, before using a mortar gun to inject the expansion mortar into the screw hole, it is necessary to replace the straight or elbow grouting end according to the position of the screw hole. Usually, the grouting end is connected to the mortar gun through a thread. Due to the lack of a mechanism for conveniently replacing the grouting end, the staff needs to continuously rotate the grouting end to disassemble it. Based on this, we propose an external wall screw hole sealing structure. Utility Model Content

In addition, the adjusting mechanism can be used to easily separate the grouting end 6 from the installing mechanism, thereby removing the restriction of the installing mechanism and facilitating the separation of the grouting end 6 from the mortar gun 3, so as to conveniently replace the straight or elbow grouting end 6 according to the position of the screw hole 2.

[0024] Specifically, the installation mechanism includes an embedding tube 5 , a slot 4 is provided at one end of the mortar gun 3 , one side of the embedding tube 5 is fixedly connected to one side of the grouting end 6 , and the embedding tube 5 is located inside the slot 4 .

[0025] In this embodiment, a sealing sleeve is provided on the outer wall of the embedding tube 5 .

[0026] Specifically, two extension plates 15 are fixedly connected to the outer wall of the grouting end 6 . The two extension plates 15 are symmetrically arranged along the circumference of the grouting end 6 . Positioning holes 16 are opened on the outer sides of the two extension plates 15 .

[0027] In this embodiment, the inner side surfaces of the two extension plates 15 are both configured as arc-shaped surfaces recessed toward the outer side of the mortar gun 3 .

[0028] Specifically, the adjustment mechanism includes a threaded barrel 7, the inner wall of the threaded barrel 7 is connected to the outer wall of the mortar gun 3 through a thread, a plurality of support rods 8 are fixedly connected to the periphery of the threaded barrel 7, the plurality of support rods 8 are equidistantly arranged in a circular array, one end of the outer sides of the plurality of support rods 8 is fixedly connected to the same guide rail 9, two sliders 10 are slidably connected to the periphery of the guide rail 9, the two sliders 10 are symmetrically arranged in a circular array, one end of the outer sides of the two sliders 10 are both fixedly connected to a fixed rod 11, a movable plate 13 is slidably connected to the outer wall of the fixed rod 11, a support spring 12 is sleeved on the outer side of the fixed rod 11, one end of the support spring 12 is fixedly connected to the outer side of the movable plate 13, and the other end is fixedly connected to the inner side of the fixed rod 11, and a positioning block 14 is fixedly connected to the inner side of the movable plate 13.

[0033] In this embodiment, since the width of the positioning block 14 is smaller than the width of the positioning hole 16 , the positioning block 14 can be easily embedded in the positioning hole 16 .

[0034] The working principle and use process of the utility model are as follows: when in use, first, after selecting a suitable shape of the grouting end 6, the embedded tube 5 on one side of the grouting end 6 is inserted into the inside of the card slot 4. Due to the effect of the sealing sleeve on the outside of the embedded tube 5, the outer wall of the embedded tube 5 drives the sealing sleeve to contact the inner wall of the card slot 4. At the same time, the two extension plates 15 on the outer wall of the grouting end 6 move one side of the outer wall of the mortar gun 3. Then, the movable plate 13 is pulled toward the outside of the threaded tube 7, so that the movable plate 13 moves on the fixed rod 11 while driving the supporting spring 12 to be compressed. Then, the slider 10 is pulled so that the slider 10 slides on the guide rail 9, so that the slider 10 drives the positioning block 14 to quickly locate to the position of the extension plate 15, so that the positioning block 14 is aligned with the positioning hole 16, and the movable plate 13 is released. Due to the reaction force of the supporting spring 12, the movable plate 13 drives the positioning block 14 to be embedded in the positioning hole 16.

[0035] Secondly, the threaded barrel 7 is rotated counterclockwise by a quarter of a turn to move the threaded barrel 7 away from the grouting end 6, so that the movable plate 13 drives one side of the positioning block 14 to be in close contact with the inner side of the positioning hole 16, so that the embedded barrel 5 drives the sealing sleeve to be in close contact with the card slot 4, thereby limiting and fixing the position of the grouting end 6, and at the same time ensuring the sealing of the connection between the grouting end 6 and the mortar gun 3, using the mortar gun 3 to suck in the expansion mortar, and the grouting end 6 is embedded in the screw hole 2, and then the mortar gun 3 is used to squeeze the expansion mortar into the screw hole 2 to perform the plugging work;

[0036] Next, when disassembly and cleaning is required, the threaded barrel 7 is rotated clockwise so that the threaded barrel 7 drives the positioning block 14 to not fit tightly against the inner wall of the positioning hole 16, and the two movable plates 13 are pulled toward the outside of the threaded barrel 7 to separate the positioning block 14 from the positioning hole 16, and then the grouting end 6 is pulled out of the mortar gun 3, so as to conveniently replace the straight or elbow grouting end 6 according to the position of the screw hole 2.
