Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, and in particular to an early demolition support device for building civil engineering. Background Technology

[0002] Early stripping support devices are a type of support device used to achieve early removal of floor slabs. Most existing early stripping support devices have relatively simple structures. Since the width of the early stripping support device cannot be adjusted, a specific width of early stripping support device is required when supporting the module, which reduces the practicality of the early stripping support device. At the same time, the existing support devices are not convenient for directly supporting modules with a certain degree of inclination.

[0003] To address the aforementioned issues, we propose an early demolition support device for building construction projects. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the background art by proposing an early demolition support device for building civil engineering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a building construction early demolition support device, comprising a base plate, on which a vertically upward-arranged support pipe is fixed; a vertical clearance groove 1 is formed on the right wall of the support pipe; a lifting pipe is slidably inserted inside the support pipe; vertical clearance grooves 2 are symmetrically formed on the front and rear walls of the lifting pipe; a clearance groove 3 corresponding to clearance groove 1 is formed on the right wall of the lifting pipe; a fixing plate 1 located outside the support pipe is fixed to the upper end of the lifting pipe; a vertically upward-arranged fixing plate 2 is fixedly connected to the rear end of the fixing plate 1; and support plate 1 and support plate 2 are symmetrically arranged on the fixing plate 2. The first support plate and the second support plate are respectively close to the left and right ends of the second fixed plate, and the lower ends of the first support plate and the second support plate are rotatably connected to the second fixed plate. The middle of the front wall of the first support plate and the second support plate are rotatably connected to the connecting rod. The front wall of the support tube has two vertically arranged guide grooves symmetrically arranged on the left and right. A slider is slidably arranged in the guide groove. A threaded rod is threadedly inserted into the slider. The lower end of the connecting rod is provided with a clearance hole. The connecting rod is movably sleeved on the corresponding threaded rod through the clearance hole. A knob is fixed on the outer end of the threaded rod. A traction mechanism is provided between the lifting tube and the support tube.

[0006] In the aforementioned early demolition support device for building construction, the traction mechanism includes two support seats symmetrically fixed to the right outer wall of the support pipe. A roller shaft is commonly provided on the two support seats. A fixing plate three is fixed to the rear side wall of the support pipe. The right end of the fixing plate three extends out of the support pipe and is provided with a rotating shaft located on the right side of the support pipe. A crank handle is fixed to the rear end of the rotating shaft. A rope roller corresponding to the clearance groove one is fixed to the front end of the rotating shaft. A steel wire rope is wound on the rope roller. A roller shaft two is provided between the front and rear walls of the support pipe, near its upper end, and the roller shaft two is located in the clearance groove two. A connecting block is fixed to the middle of the lower end of the lifting pipe. The steel wire rope passes over the upper side of the roller shaft one and roller shaft two and is fixedly connected to the connecting block. A limited rotation mechanism is provided between the rotating shaft and the fixing plate three.

[0007] In the aforementioned early demolition support device for building construction, the rotation limiting mechanism includes a friction disc fixedly sleeved on a rotating shaft. A sliding rod located to the left of the friction disc is fixed to the rear wall of the fixing plate three. A sliding sleeve is slidably sleeved on the sliding rod. An extension rod is fixed to the right wall of the sliding sleeve. A pressure block facing the friction disc is fixed to the front wall of the extension rod. A threaded rod two is threadedly inserted into the rear end of the sliding rod. A knob two located behind the sliding sleeve is fixed to the rear end of the threaded rod two.

[0008] In the aforementioned early demolition support device for building construction, extension plates extend outward from all four corners of the base plate.

[0009] In the aforementioned early demolition support device for building construction, anti-slip pads are provided at the upper ends of both support plate one and support plate two.

[0010] In the aforementioned early demolition support device for building construction, the rotation radius of the crank handle is smaller than the distance from the pressure block to the axis of rotation.

[0011] Compared with existing technologies, the advantages of this early-stripping support device for building construction are:

[0012] This invention allows for adjustment of the tilt angle of support plate one and support plate two under the action of a connecting rod by adjusting the height of the sliders in the two guide grooves. This, in turn, adjusts the upper distance between support plate one and support plate two, enabling support for modules of different widths. When the heights of the sliders in the two guide grooves are inconsistent, the upper heights of support plate one and support plate two are unequal, which can be used to support modules with a certain inclination, making it highly practical.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-5 A building construction early demolition support device includes a base plate 1, on which a vertically upward-mounted support pipe 2 is fixed. The support pipe 2 has a square cross-section. A vertical clearance groove 3 is formed on the right wall of the support pipe 2. A lifting pipe 4 is slidably inserted into the support pipe 2. Vertical clearance grooves 5 are symmetrically formed on the front and rear walls of the lifting pipe 4. A clearance groove 6 corresponding to clearance groove 3 is formed on the right wall of the lifting pipe 4. A fixing plate 1 located outside the support pipe 2 is fixed to the upper end of the lifting pipe 4. The rear end is fixedly connected to a vertically upward fixed plate 7. Support plate 8 and support plate 9 are symmetrically arranged on the fixed plate 7. Support plate 8 and support plate 9 are respectively close to the left and right ends of the fixed plate 7, and the lower ends of support plate 8 and support plate 9 are rotatably connected to the fixed plate 7. Anti-slip pads are provided on the upper ends of support plate 8 and support plate 9. Support plate 8 and support plate 9 are used to support the module. The anti-slip pads help reduce the friction between the module and support plate 8 and support plate 9.

[0021] Both support plate 8 and support plate 9 have connecting rods 10 rotatably connected to the middle of their front walls. The front wall of support tube 2 has two vertically arranged guide grooves 11 symmetrically arranged on the left and right sides. A slider is slidably installed in each guide groove 11, and a threaded rod is threadedly inserted into the slider. Each connecting rod 10 has a clearance hole at its lower end, allowing it to be movably fitted onto the corresponding threaded rod. A knob 12 is fixed to the outer end of the threaded rod, located outside the connecting rod 10. Tightening the knob 12 presses the corresponding connecting rod 10 against the outer wall of support tube 2, thus fixing support plate 8 and support plate 9. When the sliders in the two guide grooves 11 are at the same height, the upper ends of support plate 8 and support plate 9 are at the same height under the linkage of the connecting rods 10. The distance between the upper ends of support plate 8 and support plate 9 increases as the sliders rise, facilitating support for modules of different widths. When the heights of the two sliders are not the same, the upper heights of support plate 8 and support plate 9 are not the same, which can be used to support modules with an inclination.

[0022] A traction mechanism is provided between the lifting pipe 4 and the support pipe 2. The traction mechanism includes two support seats 13 symmetrically fixed to the right outer wall of the support pipe 2. The two support seats 13 are close to the upper end of the support pipe 2 and are located on the front and rear sides of the clearance groove 3, respectively. A roller 14 is provided on both support seats 13. A fixing plate 3 15 is fixed to the rear side wall of the support pipe 2. The fixing plate 3 15 is close to the middle of the support pipe 2. The right end of the fixing plate 3 15 extends out of the support pipe 2 and is provided with a rotating shaft 16 located on the right side of the support pipe 2. A crank handle 17 is fixed to the rear end of the rotating shaft 16, and a handle 17 is fixed to the front end of the rotating shaft 16. Corresponding to the clearance groove 3, the rope roller 18 is wound with a steel wire rope 19. The support tube 2 is provided with a roller shaft 20 near its upper end between the front and rear walls, and the roller shaft 20 is located in the clearance groove 5. The lower middle part of the lifting tube 4 is fixed with a connecting block 21. The steel wire rope 19 passes over the upper side of the roller shaft 14 and the roller shaft 20 and is fixedly connected to the connecting block 21. The rope roller 18 can be rotated by the crank 17, and then the steel wire rope 19 is pulled by the connecting block 21 to realize the vertical movement of the lifting tube 4, thereby realizing the height adjustment of this support device.

[0023] A limited rotation mechanism is provided between the rotating shaft 16 and the fixed plate 3 15. The limited rotation mechanism includes a friction disc 22 fixedly sleeved on the rotating shaft 16. The friction disc 22 is located on the rear side of the fixed plate 3 15. A sliding rod 23 located on the left side of the friction disc 22 is fixed to the rear wall of the fixed plate 3 15. A sliding sleeve 24 is slidably sleeved on the sliding rod 23. The rear end of the sliding sleeve 24 extends out of the sliding rod 23. An extension rod is fixed to the right wall of the sliding sleeve 24. A pressure block 25 facing the friction disc 22 is fixed to the front wall of the extension rod. A threaded rod 25 is threadedly inserted into the rear end of the sliding rod 23. The rear end of the threaded rod 25... A knob 26 is fixed on the rear side of the sliding sleeve 24. By rotating the knob 26, the knob 26 presses the sliding sleeve 24, thereby pressing the pressure block 25 against the friction disc 22, thus fixing the rotating shaft 16 and keeping the lifting tube 4 fixed relative to the support tube 2 in a static state. Extension plates 27 extend outward from the four corners of the base plate 1 to increase the force-bearing area of ​​the base plate 1, which helps to improve the stability of the support tube 2. The rotation radius of the crank handle 17 is smaller than the distance from the pressure block 25 to the axis of the rotating shaft 16, so as to avoid the pressure block 25 restricting the rotation of the crank handle 17.

[0024] This early disassembly support device can adjust the tilt angle of support plate 18 and support plate 29 under the action of connecting rod 10 by adjusting the height of the sliders in the two guide grooves 11. This, in turn, adjusts the upper distance between support plate 18 and support plate 29, thus supporting modules of different widths. When the height of the sliders in the two guide grooves 11 is inconsistent, the upper heights of support plate 18 and support plate 29 are unequal, which can be used to support modules with a certain inclination, making it highly practical.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
