Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a tool-type aluminum mold root blocking device. Background Art

[0002] With the gradual promotion and application of aluminum formwork technology, the quality of aluminum formwork has been recognized, but the problem of aluminum formwork root rot still exists. During the construction of aluminum alloy formwork, a gap of about 1cm is usually left at the base of the formwork to facilitate the removal of the aluminum formwork. Traditional aluminum formwork root mortar sealing technology mostly uses mortar to seal the gap at the base of the aluminum formwork.

[0003] The following problems still exist in the traditional aluminum mold root sealing process:

[0004] 1. The traditional method of directly plugging by filling mortar is cumbersome to operate, with low construction efficiency, and cannot meet the construction progress requirements of standard layers. In addition, it is easy to cause mortar leakage due to loose plugging, which affects the construction quality.

[0005] 2. Sealing the base of the aluminum formwork by filling mortar is not only prone to loose sealing, but also leads to material waste and rework due to leakage, increasing the ineffective cost of the project.

[0006] In response to the above problems, the present invention document proposes a tool-type aluminum mold root sealing device. Summary of the Invention

The outer wall of the round rod 33 is provided with a second spring 35 fixedly connected to the push plate 34, and the other end of the second spring 35 is fixedly connected to the push plate 11; when the push plate 11 moves, the thrust of the second spring 35 on the push plate 34 can push the angle iron 9 and the sponge blocking pad 10 toward the wall structure 1 to be cast, and then the sponge blocking pad 10 extends to the gap between the L-shaped metal reinforcement 3 and the ground under the extrusion of the pin piece 8 and the push plate 34, thereby completing the blocking of the root of the aluminum formwork 2.

[0065] Reference Figure 3 and Figure 7A first inclined surface 30 is provided on one side of the pin piece 8, and a second inclined surface 31 is provided on the side of the L-shaped metal reinforcement 3 close to the pin piece 8, and the second inclined surface 31 cooperates with the first inclined surface 30; when the push plate 11 pushes the pin piece 8 to move toward the wall structure 1 to be cast, the friction between the pin piece 8 and the L-shaped metal reinforcement 3 can be reduced through the cooperation of the first inclined surface 30 and the second inclined surface 31.

[0066] Reference Figure 6 The bottom of the aluminum formwork 2 close to the wall structure 1 to be cast is fixedly connected with a stop bar 29 by bolts, and the stop bar 29 is used to limit the L-shaped metal reinforcement 3.

[0067] Reference Figure 10 and Figure 11 The top of the trapezoidal pin 23 is fixedly connected to the top of the first sliding groove 22, and the top of the trapezoidal pin 23 is fixedly connected to the top of the first sliding groove 22. The top of the pin piece 8 is provided with a first card slot 26 that engages with the trapezoidal pin 23. The top of the trapezoidal pin 23 is fixedly connected to the sliding rod 24 that slides through the fixed block 21 by bolts. The outer wall of the sliding rod 24 is provided with a first spring 25 that is fixedly connected to the top of the trapezoidal pin 23, and the top of the first spring 25 is fixedly connected to the top of the first sliding groove 22; the second nut 12 is rotated in the opposite direction, and the second nut 12 drives the push plate 11 to move outward. Since the trapezoidal pin 23 is stuck in the first card slot 26 when the push plate 11 moves toward the direction of the wall structure 1 to be cast, the push plate 11 moves outward. At this time, the push plate 11 moves outward and can pull the pin piece 8 outward through the trapezoidal pin 23, and there is no need to manually remove the pin piece 8 again.

[0068] Reference Figure 2 、 Figure 3 、 Figure 14 and Figure 15 The top inner wall of the angle iron 9 is provided with a plurality of tooth blocks 36 for increasing the friction between the sponge sealing pad 10, the bottom inner wall of the slide groove 7 is provided with a plurality of second slots 37, the bottom of the pin piece 8 is provided with a plurality of second sliding slots 38, the second sliding slot 38 is slidably connected with a trapezoidal plate 39 that engages with the second slot 37, the top inner wall of the trapezoidal plate 39 is fixedly connected with a third spring 40, and the top end of the third spring 40 is fixedly connected to the top inner wall of the second sliding slot 38; the pin piece 8 moves outward When the angle iron 9 is removed from the mold, the cooperation between the trapezoidal plate 39 and the second slot 37 can drive the angle iron 9 outward. In addition, the tooth block 36 can increase the friction between the angle iron 9 and the sponge sealing pad 10. The angle iron 9 can bring out the sponge sealing pad 10, and then the movement of the push plate 11 can quickly complete the disassembly of the sponge sealing pad 10, the angle iron 9 and the pin 8, thereby improving the efficiency of the root sealing construction of the aluminum template 2, and the sponge sealing pad 10, the angle iron 9, the pin 8 and the pin 6 can be reused.

[0069] The method for using the tool-type aluminum mold root sealing device includes the following steps:

[0070] S1. Install two aluminum formworks 2 on both sides of the wall structure 1 to be cast. At this time, there is a certain gap between the two aluminum formworks 2 and the ground. Slide the L-shaped metal reinforcement 3 at the bottom of the aluminum formwork 2 toward the wall structure 1 to be cast through the cooperation of the T-slot 28 and the T-block 27. The first inclined surface 30 limits the L-shaped metal reinforcement 3. Then, the pin 6 is passed through the aluminum formwork 2 and the L-shaped metal reinforcement 3 to preliminarily fix the L-shaped metal reinforcement 3. Then, multiple bidirectional screws 4 are respectively passed through the two aluminum formworks 2, and the bidirectional screws 4 can pass through the L-shaped metal reinforcement 3. The L-shaped metal reinforcement 3 can be further fixed to the aluminum formwork 2 through the cooperation of the first nut 5 and the bidirectional screw 4 and the obstruction of the first inclined surface 30.

[0071] S2, cover the angle iron 9 on the top of the sponge sealing pad 10 and place it at the root gap of the aluminum template 2;

[0072] S3. Slide the pin piece 8 along the slide groove 7 toward the direction of the wall structure 1 to be cast, then put the push plate 11 on the outer wall of the multiple bidirectional screws 4, rotate the second nut 12, and the second nut 12 drives the push plate 11 to move in the direction of the wall structure 1 to be cast. The push plate 11 touches the pin piece 8, and the push plate 11 pushes the pin piece 8 to move. Then, the pin piece 8 can squeeze the angle iron 9 and the sponge sealing pad 10 under the cooperation of the first inclined surface 30 and the second inclined surface 31. When the pin piece 8 moves, the trapezoidal plate 39 extends into the second slot 37 under the elastic force of the third spring 40;

[0073] S4, when the push plate 11 moves, the thrust of the push plate 34 by the second spring 35 can push the angle iron 9 and the sponge sealing pad 10 toward the wall structure 1 to be cast, and then the sponge sealing pad 10 extends to the gap between the L-shaped metal reinforcement 3 and the ground under the extrusion of the pin piece 8 and the push plate 34, thereby completing the sealing of the root of the aluminum formwork 2. In addition, the push plate 11 drives the sleeve 15 to cooperate with the rotating shaft 17. When the rotating shaft 17 is inserted into the sleeve 15, the cooperation of the protrusion 16 and the arc groove 20 drives the rotating shaft 17 and the cam 18 to rotate. When the cam 18 rotates downward, it can squeeze the pin 6 downward, so that the pin 6 squeezes the angle iron 9 at the same time, further squeezing the sponge sealing pad 10, so that the sponge sealing pad 10 can be sealed, and leakage can be avoided during the later casting of the wall structure 1 to be cast;

[0074] S5. When the pouring task between the two aluminum formworks 2 is completed and the concrete has solidified, the second nut 12 is rotated in the opposite direction. The second nut 12 drives the push plate 11 to move outward. Since the trapezoidal pin 23 is engaged in the first slot 26 when the push plate 11 moves toward the wall structure 1 to be poured, the push plate 11 can move outward by the trapezoidal pin 23, and there is no need to manually remove the pin 8 again.

[0075] S6. When the pin piece 8 moves outward, the cooperation between the trapezoidal plate 39 and the second slot 37 can drive the angle iron 9 outward. In addition, the tooth block 36 can increase the friction between the angle iron 9 and the sponge sealing pad 10, and the angle iron 9 can bring out the sponge sealing pad 10. Then, the movement of the push plate 11 can quickly complete the disassembly of the sponge sealing pad 10, the angle iron 9 and the pin piece 8, thereby improving the efficiency of the sealing construction at the root of the aluminum template 2, and the sponge sealing pad 10, the angle iron 9, the pin piece 8 and the pin 6 can be reused.
