Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a device for fixing external scaffolding in building construction. Background Technology

[0002] Building scaffolding refers to temporary structural frames erected for building construction. It is mainly used for exterior wall masonry, exterior facade decoration, and reinforced concrete engineering, including scaffolding. It is currently the most widely used type of scaffolding on construction sites. Its characteristics include simple and convenient construction, strong load-bearing capacity, and wide applicability. It can be used in conjunction with different structures. In order to provide a stable working space for construction workers, fixing devices are required to improve the stability of the scaffolding.

[0003] There are many existing technologies for fixing devices, such as:

[0004] Chinese patent application CN218467064U discloses a scaffold fixing device with a clamping structure, comprising: a scaffold body, a front clamping plate, a fixing sleeve, and a suction cup. A base is provided on the lower outer side of the scaffold body, and a U-shaped receiving plate is provided above the base. The front clamping plate is rotatably connected to the inner front end of the receiving plate, and a rear clamping plate is snapped onto the outer rear end of the front clamping plate. Both the inner and outer right ends of the front and rear clamping plates have arc-shaped structures. The fixing sleeve is fixedly connected to the lower middle surface of the receiving plate, and an inner sleeve rod is nested and fixed inside the fixing sleeve. The suction cup is adhered and fixed to the inner middle right end of the base. This scaffold fixing device with a clamping structure facilitates the clamping and fixing of different scaffold bodies, and allows the fixing device to adhere and fix to the ground, thereby stabilizing the scaffold body and preventing slippage and overturning, thus improving the safety of workers.

[0005] Existing fixing devices are used to attach to the ground to enhance the stability of the scaffold. However, when the scaffold needs to be moved, the fixing devices must be manually separated from the ground one by one, which is a tedious and labor-intensive process. Therefore, we propose a fixing device for building scaffolds. Utility Model Content

[0006] The purpose of this utility model is to solve the above-mentioned shortcomings and provide a device for fixing building scaffolding;

[0007] To achieve the above objectives, this utility model provides a fixing device for building scaffolding, including a scaffolding body. Two sets of fixing components are detachably provided on the lower surfaces of both sides of the scaffolding body. Each fixing component includes a fixing seat fixedly installed on the lower surface of two legs of the scaffolding body. A base plate is fixedly provided on the outer side of the bottom of the fixing seat. A horizontal plate is fixedly installed between the tops of the two fixing seats on the side away from the base plate. A movable component is provided on the horizontal plate.

[0008] As a further improvement to this technical solution, a diagonal brace is fixedly provided between the base plate and the fixed seat, and a ground spike is provided on the base plate, with the ground spike penetrating through the base plate below.

[0009] As a further improvement to this technical solution, the moving component includes a mounting plate that is vertically slidably disposed below the horizontal plate, and a plurality of casters are evenly disposed on the bottom of the mounting plate to facilitate the movement of the outer frame body.

[0010] As a further improvement to this technical solution, the moving component also includes a lead screw rotatably mounted on the horizontal plate. The lead screw passes through the horizontal plate at its lower end, and a lifting cylinder is threadedly connected to its lower surface. The bottom of the lifting cylinder is fixedly connected to the top of the mounting plate in a centered manner.

[0011] As a further improvement to this technical solution, two telescopic rods are symmetrically arranged between the top of the base plate and the bottom of the horizontal plate.

[0012] As a further improvement to this technical solution, a handwheel is fixedly installed on the top of the lead screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This device, used in building scaffolding fixing, increases the contact area between the scaffold body and the ground through a fixing base and a base plate. Then, the ground spikes on the base plate are embedded in the ground, further fixing the scaffold body to the ground and preventing it from tipping over, thus increasing its stability. When the device's position needs to be adjusted, the screw is rotated via a handwheel, and the lifting cylinder moves downwards along the threaded structure on the screw surface. During this downward movement, the bottom mounting plate and casters move downwards. When the casters contact the ground, they continue to lift downwards. Under the lifting force, the ground spikes embedded in the ground are subjected to an upward pull, gradually loosening and being pulled out. No additional tools or equipment are needed, reducing tool handling and operation steps, thus improving work efficiency. Furthermore, the scaffold body can be moved on the ground via the casters to switch to different work areas for convenient subsequent use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 As shown, this embodiment provides a fixing device for building scaffolding, including a scaffolding body 1. The feature is that two sets of fixing components 2 are detachably provided on the lower surfaces of both sides of the scaffolding body 1. The fixing components 2 include fixing seats 21 fixedly provided on the lower surfaces of the two legs of the scaffolding body 1. A base plate 22 is fixedly provided on the outer side of the bottom of the fixing seat 21. A horizontal plate 23 is fixedly provided between the top of the two fixing seats 21 on the side away from the base plate 22. A moving component 3 is provided on the horizontal plate 23.

[0025] The fixed base 21 and the base plate 22 are used to make the outer frame body 1 more firmly set on the ground, and the movable component 3 can move vertically on the horizontal plate 23 to adjust the distance from the ground, so as to hide and pull out.

[0026] The improvement in this embodiment is that the fixing component 2 secures the outer frame body 1 to the ground, increasing the stability of the outer frame body 1 and preventing it from tipping over. When the outer frame body 1 needs to be adjusted for use, the moving component 3 moves vertically downwards to the ground. During this process, under the action of the lifting force, the fixing component 2 is subjected to an upward pulling force and leaves the ground. No additional tools or equipment are required, reducing the handling and operation of tools and improving work efficiency. At this time, the outer frame body 1 can be moved on the ground by the moving component 3 to switch to different work areas for convenient subsequent use.

[0027] To further improve the stability of the external frame body 1 relative to the ground, therefore, as Figures 1-4As shown, a diagonal brace 24 is fixedly installed between the base plate 22 and the fixed seat 21. A ground spike 25 is installed on the base plate 22, with the ground spike 25 penetrating through the base plate 22. When the equipment is in use, the legs of the outer frame body 1 are inserted into the inner cavity of the fixed seat 21, and the fixed seat 21 is fixed to the surface of the legs of the outer frame body 1 by screws. The base plate 22 can increase the contact area between the legs of the outer frame body 1 and the ground, so that the load of the outer frame body 1 can be transferred to the ground more evenly, thereby reducing the pressure on the ground and preventing the scaffolding from sinking into the ground due to excessive local pressure. Especially when building scaffolding on soft soil foundations or uneven ground, it effectively improves the stability of the scaffolding. Then, the ground spike 25 is inserted into the ground to temporarily fix the base plate 22 to the ground, which helps to further improve the stability of the outer frame body 1 and the ground, helps to prevent the equipment from tipping over, and improves the safety during use.

[0028] Considering that work needs to be carried out in different areas during construction, therefore, Figures 1-4 As shown, the movable component 3 includes a mounting plate 31 that is vertically slidably disposed below the horizontal plate 23. Multiple casters 32 are evenly distributed at the bottom of the mounting plate 31. When the outer frame body 1 needs to be moved or its position adjusted, the mounting plate 31 and the casters 32 are moved downwards. When the casters 32 contact the ground, they continue to lift downwards. Under the action of the lifting force, the ground spikes 25 inserted into the ground are subjected to an upward pulling force, gradually loosening and being pulled out. No additional tools or equipment are required, reducing the handling and operation of tools and improving work efficiency. At this time, the outer frame body 1 can move on the ground through the casters 32 to switch to different work areas for convenient subsequent use.

[0029] When the mounting plate 31 and casters 32 move vertically, in order to make the movement of the mounting plate 31 and fixing assembly 2 more convenient, therefore, as follows: Figures 1-3 As shown, the movable component 3 also includes a lead screw 33 rotatably mounted on the horizontal plate 23. The lead screw 33 passes through the horizontal plate 23 and has a lifting cylinder 34 threadedly connected to its lower surface. The bottom of the lifting cylinder 34 is fixedly connected to the top of the mounting plate 31 in the center. When the mounting plate 31 and the casters 32 need to be moved downward, the lead screw 33 is rotated, and then the lifting cylinder 34 moves downward along the threaded structure on the surface of the lead screw 33. During the downward movement of the lifting cylinder 34, the bottom mounting plate 31 and the casters 32 move downward. Conversely, when the lead screw 33 is rotated in the opposite direction, the lifting cylinder 34 moves upward along the threaded structure on the surface of the lead screw 33, and the bottom mounting plate 31 and the casters 32 move upward, so that the casters 32 return to their original positions. This facilitates the upward and downward movement of the mounting plate 31 and the casters 32, and makes it easier to move the mounting plate 31 out or hide it, allowing the outer frame body 1 to switch to different states, which is convenient for subsequent use by staff.

[0030] When the caster wheel 32 moves up and down, in order to make it move in the set direction, therefore, as Figures 1-3 As shown, two telescopic rods 35 are symmetrically arranged between the top of the base plate 22 and the bottom of the horizontal plate 23. When the mounting plate 31 and the caster 32 move up and down, the telescopic rods 35 limit the horizontal movement of the mounting plate 31, so that the mounting plate 31 can only move up and down in the vertical direction, which is conducive to smoothly adjusting the caster 32.

[0031] When the lead screw 33 rotates, in order to facilitate the operator's control of the lead screw 33, therefore, as Figures 1-3 As shown, a handwheel 36 is fixedly installed on the top of the lead screw 33. The operator controls the rotation of the lead screw 33 through the handwheel 36, which facilitates the subsequent up-and-down movement of the caster wheel 32 to switch the operating status of the equipment.

[0032] In practical use, the external scaffolding fixing device of this utility model inserts the legs of the external scaffold body 1 into the inner cavity of the fixing seat 21, and fixes the fixing seat 21 to the surface of the legs of the external scaffold body 1 with screws. Then, the ground spikes 25 are inserted into the ground to temporarily fix the base plate 22 to the ground. When it is necessary to adjust the position of the external scaffold body 1, the handwheel 36 is turned to drive the lead screw 33 to rotate. Then, the lifting cylinder 34 moves downward along the threaded structure on the surface of the lead screw 33. The lifting cylinder 34 drives the mounting plate 31 and the universal wheel 32 to move downward. When the universal wheel 32 contacts the ground, it continues to lift downward. Under the action of the lifting force, the ground spikes 25 inserted into the ground are subjected to an upward pull, gradually loosening and being pulled out. At this time, the external scaffold body 1 can move on the ground through the universal wheel 32. Conversely, when the lead screw 33 is rotated in the opposite direction, the lifting cylinder 34 moves upward along the threaded structure on the surface of the lead screw 33, driving the bottom mounting plate 31 and the universal wheel 32 to move upward, so that the universal wheel 32 returns to its position.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
