Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an elastic blocking device for the bottom of an aluminum alloy formwork support. Background Art

[0002] As a new generation of building formwork, aluminum alloy formwork is widely used in various countries and regions around the world and has achieved remarkable results. Due to the high rigidity, modularization and standardization of aluminum alloy formwork, there is a certain gap between the bottom of the aluminum alloy formwork and the concrete slab surface. When the on-site wall column formwork is installed, it is necessary to seal the bottom of the wall column. The application number is: 201922228282.1, which discloses a bottom anti-leakage slurry device for aluminum alloy formwork. A rubber strip is provided in the gap between the angle aluminum and the concrete slab surface, and the rubber strip is fixed in the gap between the angle aluminum and the concrete slab surface by a lifting device. The lifting device of the utility model adjusts the lifting of the rubber strip, thereby realizing the rapid sealing of the gap between the angle aluminum and the concrete slab surface, which is faster than the traditional sealing method. Its structure is simpler than the anti-leakage slurry device at the bottom of other aluminum alloy formworks, and it is more convenient for workers to install, replace and disassemble, which is more conducive to saving construction time.

[0003] The above scheme uses a screw to drive the rubber strip to slide down and fit with the concrete slab surface to achieve a sealing effect. However, in actual applications, the aluminum alloy formwork will inevitably vibrate during construction, causing the position to change, so that the rubber strip and the concrete slab surface no longer fit. At this time, the rubber strip cannot play a sealing role, and the position of the rubber strip needs to be adjusted again, which is very cumbersome. Utility Model Content

[0025] The bottom end of the first threaded bolt 103 is rotatably connected to the mounting plate 2, the side wall of the mounting plate 2 is threadedly connected to the second threaded bolt 201, the end of the second threaded bolt 201 located in the inner cavity of the mounting plate 2 is rotatably connected to the clamping plate 202, the top of the clamping plate 202 is fixedly connected to the elastic component 203, the bottom end of the elastic component 203 is fixedly connected to the clamping block 204, and the bottom end of the clamping block 204 is fixedly connected to the rubber pad 205;

[0026] The top of the sleeve 102 is threadedly connected with a plurality of fixing bolts 206, and the fixing bolts 206 penetrate the upper aluminum alloy template 101 and extend to the inner cavity of the lower aluminum alloy template 1;

[0027] The outer wall of the lower sleeve 102 located at the top of the lower aluminum alloy template 1 is threadedly connected with a nut 207;

[0028] It should be noted that: the sleeve 102 is fixed to the surface of the lower aluminum alloy template 1 and the upper aluminum alloy template 101 by using the fixing bolt 206, and then the sleeve 102 is tightened by rotating the nut 207 to ensure that the lower aluminum alloy template 1 and the upper aluminum alloy template 101 are tightly fitted, and then the first threaded bolt 103 is rotated to rotate the first threaded bolt 103 to the bottom of the lower aluminum alloy template 1, and the mounting plate 2 is rotated and installed at the bottom of the first threaded bolt 103, and then the second threaded bolt 201 is rotated, and the second threaded bolt 201 drives the clamping plate 202 to move closer to the side wall of the lower aluminum alloy template 1 until the clamping plate 202 fits with the side wall of the lower aluminum alloy template 1, and then the first threaded bolt 103 is rotated again to press the rubber pad 205 against the finished surface of the structure, so as to complete the blocking of the bottom of the lower aluminum alloy template 1, and at this time, the elastic component 203 located between the clamping block 204 and the clamping plate 202 is compressed. When the device changes slightly, under the action of the elastic component 203, the rubber pad 205 will still play a sealing role.

[0029] Reference Figure 1-4 The first clamping column 3 is slidably connected to both sides of the inner wall of the first threaded bolt 103, and the end of the first clamping column 3 located in the inner cavity of the first threaded bolt 103 is fixedly connected to the sliding plate 301;

[0031] A first spring 303 is fixedly connected between the sliding plate 301 and the first threaded bolt 103;

[0032] It should be noted that: when the first threaded bolt 103 and the mounting plate 2 are rotated and installed, the first clamping column 3 is pressed into the inner cavity of the first threaded bolt 103, and the first clamping column 3 will drive the sliding plate 301 and the second clamping column 302 to slide into the inner cavity of the first threaded bolt 103. At this time, the first spring 303 is compressed. When the first clamping column 3 and the second clamping column 302 both slide into the inner cavity of the first threaded bolt 103, the first threaded bolt 103 and the mounting plate 2 can be installed. After the installation is completed, the first clamping column 3 is released. At this time, under the action of the rebound force of the first spring 303, the second clamping column 302 slides toward the outside of the first threaded bolt 103 to the inner cavity of the mounting plate 2, thereby completing the rotational installation of the first threaded bolt 103 and the mounting plate 2.

[0033] Reference Figure 1-4 The elastic component 203 includes a sleeve 304, a sliding column 305 and a second spring 306. The sleeve 304 is fixedly mounted on the inner top wall of the card plate 202. The inner wall of the sleeve 304 is slidably connected with the sliding column 305, and the sliding column 305 is fixedly connected to the card block 204.

[0034] A second spring 306 is fixedly connected between the sliding column 305 and the sleeve 304;

[0035] It should be noted that: when the rubber pad 205 at the bottom of the block 204 is in close contact with the finished surface of the structure, the first threaded bolt 103 continues to rotate. At this time, the first threaded bolt 103 drives the mounting plate 2 and the card plate 202 to continue to slide downward, and the second spring 306 located between the sliding column 305 and the sleeve 304 is compressed to generate a rebound force. When the device changes slightly, under the action of the rebound force of the second spring 306, the sliding column 305 drives the block 204 and the rubber pad 205 to adjust their positions, which will still make the rubber pad 205 in close contact with the finished surface of the structure and will not affect the sealing effect.

[0036] Operation method: Use the fixing bolt 206 to fix the sleeve 102 on the surface of the lower aluminum alloy template 1 and the upper aluminum alloy template 101, then tighten the sleeve 102 by rotating the nut 207 to ensure that the lower aluminum alloy template 1 and the upper aluminum alloy template 101 are tightly fitted, and then rotate the first threaded bolt 103 to the bottom of the lower aluminum alloy template 1, press the first clamping column 3 into the inner cavity of the first threaded bolt 103, the first clamping column 3 will drive the sliding plate 301 and the second clamping column 302 to slide into the inner cavity of the first threaded bolt 103, at this time, the first spring 303 is compressed, when the first clamping column 3 and the second clamping column 302 both slide into the inner cavity of the first threaded bolt 103, the first threaded bolt 103 and the mounting plate 2 can be installed, after the installation is completed, release the first clamping column 3, at this time, under the action of the rebound force of the first spring 303, the second clamping column 302 slides to the outside of the first threaded bolt 103 to the inner cavity of the mounting plate 2, thereby completing the rotation installation of the first threaded bolt 103 and the mounting plate 2;

[0037] Then rotate the second threaded bolt 201, and the second threaded bolt 201 drives the clamping plate 202 to move closer to the side wall of the lower aluminum alloy template 1 until the clamping plate 202 fits with the side wall of the lower aluminum alloy template 1. At this time, rotate the first threaded bolt 103 again to make the rubber pad 205 close to the finished surface of the structure, so as to complete the blocking of the bottom of the lower aluminum alloy template 1, and continue to rotate the first threaded bolt 103. At this time, the first threaded bolt 103 drives the mounting plate 2 and the clamping plate 202 to continue to slide downward, and the second spring 306 located between the sliding column 305 and the sleeve 304 is compressed to generate a rebound force. When the device changes slightly, under the action of the rebound force of the second spring 306, the sliding column 305 drives the clamping block 204 and the rubber pad 205 to adjust their positions, which will still make the rubber pad 205 close to the finished surface of the structure and will not affect the sealing effect.
