Description

Technical Field

[0001] The utility model belongs to the technical field of scaffolding, and particularly relates to an adjustable scaffolding for building construction. Background Technique

[0002] Scaffolds are often used in building construction. A scaffold is a temporary structure used for building, repairing, or cleaning high-rise buildings or other structures, aiming to provide a safe and stable working platform for workers and facilitate them to carry tools and materials required during building construction.

[0003] At present, there are many types of scaffolds on the market. For example, a scaffold that is easy to adjust is disclosed on the Chinese Patent Network, and its publication number is CN220645094U. This type of scaffold can adjust the height and is convenient to use stably on uneven ground. However, there are some defects and deficiencies to be improved: (1) In order to facilitate the movement of some existing scaffolds, rollers are usually installed at the bottom. However, the rollers are often integrally connected to the scaffold and are difficult to disassemble, making it inconvenient to maintain or replace the rollers; (2) In order to improve safety performance and prevent construction workers or tools from falling from the scaffold, some existing scaffolds generally install guardrails, and the guardrails are often fixed on the scaffold boards and are difficult to disassemble, making it inconvenient to maintain or replace the guardrails; (3) Due to the reason of the structural design of some existing scaffolds, when adjusting the height of the scaffold board, the applied lifting force is often concentrated at a single point at the bottom of the scaffold board and is difficult to be evenly distributed, which will cause the scaffold board to deform due to uneven stress, not only affecting the service life of the scaffold board, but also easily causing potential safety hazards. Therefore, in view of the above problems, it is of great significance to provide an adjustable scaffolding for building construction according to the present utility model. Content of the Utility Model

[0004] The utility model provides an adjustable scaffolding for building construction. The position of the scaffolding can be moved through the rollers in the moving mechanism. After long-term use, the moving mechanism can be disassembled to facilitate the maintenance or replacement of the rollers; the lifting plate can drive the scaffold board to move up and down together to adjust the height of the scaffold board as needed. Through the mutual cooperation between the convex columns and the grooves, the lifting force applied by the lifting plate can be effectively dispersed, so that the stress at the bottom of the scaffold board is more uniform, effectively avoiding the deformation of the scaffold board due to uneven stress; the guardrail can play a protective role to prevent construction workers or tools from falling from the scaffold board, and the guardrail can be disassembled from the scaffold board to facilitate its maintenance or replacement.

[0035] Please refer to Figures 1-9As shown, the utility model is an adjustable scaffold for construction, comprising a base 1, both sides of the base 1 are L-shaped, the outer wall of which is fixedly connected with a mounting frame 2, a moving mechanism is arranged on the mounting frame 2, a pair of support rods 3 are fixedly connected to both sides of the top of the base 1, and a fixing frame 4 is fixedly connected to the base 1, a positioning mechanism is arranged below the fixing frame 4, and a hydraulic cylinder 5 is installed on the top of the fixing frame 4, a lifting plate 6 is fixedly connected to the top of the output shaft of the hydraulic cylinder 5, an adjusting slot 7 is opened on the top of the support rod 3, and a pair of support rods 3 located on both sides are fixedly connected. A plurality of climbing rods 8 are connected, and a scaffolding board 9 is arranged above the lifting board 6. A plurality of positioning rods 10 are fixedly connected to the top of the scaffolding board 9, and a pair of adjusting rods 11 are fixedly connected to both sides of the bottom of the scaffolding board 9. The diameter of the adjusting rod 11 is equal to that of the adjusting groove 7, and each adjusting rod 11 is inserted into the corresponding adjusting groove 7. The lifting board 6 can be driven to move up and down by driving the hydraulic cylinder 5. When the lifting board 6 contacts the scaffolding board 9, the scaffolding board 9 can be driven to move up and down together, so as to adjust the height of the scaffolding board 9 as needed. A guardrail is installed on the scaffolding board 9;

[0036] The moving mechanism includes a moving plate 12, which is L-shaped and has a plurality of rollers 13 mounted on its bottom. When the moving mechanism is mounted on the mounting frame 2, each roller 13 can contact the ground, and the position of the scaffold can be moved by using the rollers 13.

[0037] The positioning mechanism includes a cylinder 14, which is installed at the bottom of the fixed frame 4. The bottom end of the output shaft of the cylinder 14 passes through the base 1 and is fixedly connected to a brake plate 15. The brake plate 15 can be driven up and down by driving the cylinder 14. When the brake plate 15 contacts the ground, it can play a braking role to prevent the scaffold from being displaced during use and causing safety hazards.

[0038] The guardrail includes a plurality of positioning tubes 16, a pair of transverse railings 17 are fixedly connected between each two adjacent positioning tubes 16, and a plurality of vertical railings 18 are fixedly connected between each pair of transverse railings 17. When the guardrail is installed on the scaffolding board 9, it can play a protective role to prevent construction workers or tools from falling from the scaffolding board 9.

[0039] Among them, the cross-section of the mounting frame 2 is C-shaped, and its side wall is provided with a plurality of threaded holes 19, and the threaded holes 19 are internally threadedly connected with bolts 20 that match them. The width and thickness of the movable plate 12 are respectively equal to the length and width of the inner wall of the mounting frame 2, and the side wall surface of the movable plate 12 is provided with a plurality of threaded grooves 21 that match the bolts 20. The movable plate 12 can be inserted from below and attached to the inner wall of the mounting frame 2. At this time, by tightening the bolts 20 in the threaded holes 19, the ends of the bolts 20 can be screwed into the corresponding threaded grooves 21, so that the movable plate 12 together with the entire movable mechanism can be fixed to the mounting frame 2 through the mutual cooperation between the bolts 20 and the threaded grooves 21, and the movable mechanism can be removed by unscrewing the bolts 20 so as to maintain or replace the roller 13.

[0040] The brake plate 15 is located below the base 1, and a plurality of anti-skid pads 22 are arranged on its bottom surface. The anti-skid pads 22 are long strips and are linearly distributed equidistantly along the length direction of the brake plate 15. The surface of the anti-skid pads 22 is engraved with herringbone anti-skid patterns. The anti-skid pads 22 are made of elastic materials such as rubber and are fixed by glue or the like. When the brake plate 15 contacts the ground, the anti-skid patterns on the surfaces of the anti-skid pads 22 can increase the friction between the brake plate 15 and the ground to play an anti-skid role, thereby preventing the scaffold from slipping during use. In order to prevent slipping during use and affect stability, the climbing pole 8 is provided with an anti-slip sleeve 23, and the surface of the anti-slip sleeve 23 is engraved with a herringbone anti-slip pattern. The anti-slip sleeve 23 is made of elastic materials such as silicone and is fixed by glue or the like. The climbing pole 8 can facilitate construction workers to climb onto the scaffolding 9. When the construction workers climb using the climbing pole 8, the anti-slip pattern on the surface of the anti-slip sleeve 23 can increase the friction between their hands and feet and the climbing pole 8, so as to play an anti-slip role, thereby effectively preventing the construction workers from falling due to slipping of their hands and feet during the climbing process.

[0041] Among them, a pair of support rods 3 located at the front and rear sides are fixedly connected with reinforcing ribs 24, which are X-shaped. The reinforcing ribs 24 can play a reinforcing role to improve the overall stability of the scaffolding, thereby preventing the support rods 3 from being deformed or tilted due to long-term stress.

[0042] Among them, a plurality of grooves 25 are opened on the top surface of the lifting plate 6, and a plurality of bosses 26 are fixedly connected to the bottom of the scaffolding board 9. The bosses 26 are the same in number as the grooves 25, have equal diameters, and are distributed in a linear array. The center of each boss 26 corresponds one-to-one to the center of each groove 25. When the lifting plate 6 contacts the scaffolding board 9, each boss 26 can be aligned and inserted into the corresponding groove 25. The lifting force applied by the lifting plate 6 can be effectively dispersed through the mutual cooperation between the bosses 26 and the grooves 25, so that the force on the bottom of the scaffolding board 9 is more uniform, thereby effectively avoiding deformation of the scaffolding board 9 due to uneven force.

[0043] Among them, a plurality of anti-skid grooves 27 are provided on the top surface of the scaffolding board 9. The anti-skid grooves 27 are rectangular and are equidistantly linearly distributed along the length direction of the scaffolding board 9. The anti-skid grooves 27 can increase the friction force to play an anti-skid role, thereby effectively preventing construction workers from slipping and falling when standing on the scaffolding board 9, and also preventing tools from slipping from the scaffolding board 9.

[0044] Among them, the number of positioning cylinders 16 is the same as the positioning rods 10, and their inner diameters are equal to the rod diameters of the positioning rods 10, and the center of each positioning cylinder 16 corresponds to the center of each positioning rod 10 one by one. When the guardrail is installed on the scaffolding board 9, each positioning rod 10 can be aligned and inserted into the corresponding positioning cylinder 16, so that the guardrail can be fixed on the scaffolding board 9 by plugging, and the guardrail can be removed by pulling out the positioning cylinder 16 for maintenance or replacement.

[0045] The circuits, electronic components and chip modules involved in the utility model are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to software and methods.

[0046] The standard parts used in the application documents can all be purchased from the market. All the components in this application document can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt mature conventional means such as bolts, rivets, welding, etc. in the prior art. Machinery, parts and equipment all adopt conventional models in the prior art. The electrical components appearing in this article are all electrically connected to the external main controller and 220V AC power, and the main controller can be a conventional known device that controls the LED lamp body, etc.

[0047] The working principle of the utility model is:

[0048] When the utility model is in use, the position of the scaffold can be moved by the roller 13 in the moving mechanism. When it moves to the specified position, the cylinder 14 is driven to drive the brake plate 15 to move up and down. When the brake plate 15 contacts the ground, it can play a braking role to prevent the scaffold from being displaced during use and causing safety hazards. After that, the construction personnel can climb up the scaffolding board 9 through the climbing rod 8 so as to stand on the scaffolding board 9 for construction. The lifting plate 6 can be driven up and down by driving the hydraulic cylinder 5. When the lifting plate 6 contacts the scaffolding board 9, the scaffolding board 9 can be driven to move up and down together, so that the height of the scaffolding board 9 can be adjusted according to needs. When the lifting plate 6 contacts the scaffolding board 9, the lifting plate 6 can be driven to move up and down together. When the boards 9 are in contact, each boss 26 can be aligned and inserted into the corresponding groove 25. The mutual cooperation between the boss 26 and the groove 25 can effectively disperse the lifting force applied by the lifting board 6, so that the force on the bottom of the scaffolding board 9 is more uniform, thereby effectively avoiding the deformation of the scaffolding board 9 due to uneven force. Guardrails are installed on the scaffolding board 9 to play a protective role to prevent construction workers or tools from falling from the scaffolding board 9. After the scaffolding has been used for a long time, the guardrail can be removed by pulling out the positioning cylinder 16 for maintenance or replacement. At the same time, the moving mechanism can be removed by unscrewing the bolt 20 to maintain or replace the roller 13.
