Description

Technical Field

[0001] The invention belongs to the field of construction equipment, and in particular relates to a cantilever scaffolding jump-layer tie-in reinforcement device. Background Art

[0002] Scaffolding is a temporary construction tool set up at the construction site for workers to operate and solve vertical and horizontal transportation. It is mainly used for exterior walls, interior decoration or places with high floor heights that cannot be directly constructed. It is mainly used for construction workers to work up and down or for the maintenance of peripheral safety nets and the installation of components at high altitudes. It is usually made of bamboo, wood, steel pipes or synthetic materials.

[0003] For a long time, the accident rate was high due to the backwardness of the erection tools themselves, their construction technology and their use safety management.

[0004] When common scaffolding is installed, a fixing frame is used to fix two steel pipes together, and the fixing parts are relatively short. When fixing the two steel pipes, because the steel pipes are relatively long, when the weight borne by the scaffolding is too heavy, the scaffolding will topple over. The overall structure of a steel pipe is relatively strong and cannot be bent, so the connection between the two steel pipes will crack, causing the scaffolding to collapse. Summary of the invention

[0005] The invention provides a cantilever scaffolding jump-layer tie-in reinforcement device, aiming to solve the problem of instability during the construction of the cantilever scaffolding.

[0006] The present invention is implemented in this way: a cantilever scaffolding jump layer tie reinforcement device comprises:

[0007] A transverse tube, wherein multiple transverse tubes are provided, and multiple connecting tubes are fixedly installed between two adjacent transverse tubes. Multiple vertical tubes are provided on one side of the transverse tube, and the two vertical tubes are arranged opposite to each other. A fixing assembly for fixing the two vertical tubes is fixedly installed on one side of the transverse tube, and the fixing assembly is used to prevent the two vertical tubes from shaking forward and backward. A stretching assembly is installed on the transverse tube, and the fixing assembly on one side is stretched by the stretching assembly to fix the fixing assembly on the transverse tube;

[0008] A sleeve is sleeved on the vertical pipe, and a cross-stabilizing component is installed between the sleeve and the fixing component, so that the two vertical pipes will not shake left and right through the cross-stabilizing component.

[0009] Furthermore, the fixing assembly includes a pipe fitting arranged on one side of the horizontal tube, one end of the horizontal tube extends into the pipe fitting, and the two vertical tubes both extend into the pipe fitting. Both sides of the two vertical tubes are abutted with arc-shaped abutment plates for fixing them, and circular holes are opened on both sides of the arc-shaped abutment plates. Second bolts are slidably connected in the circular holes to fix the arc-shaped abutment plates on both sides.

[0010] Furthermore, a pulling plate is fixedly installed on one side of the arc-shaped abutment plate, a circular hole is opened on the side of the pulling plate away from the arc-shaped abutment plate, and the central axes of the circular holes are located in the same plane. The first bolts for fixing the pulling plates on both sides are slidably connected in the circular holes.

[0011] Furthermore, a fixing plate is fixedly mounted on the pipe fitting, threaded holes are provided on the fixing plate and the pipe fitting, and a first threaded knob abutting against the transverse pipe is threadedly connected in the threaded hole.

[0012] Furthermore, the stretching assembly includes a fixed column fixedly installed on the cross tube, a clamping plate is slidably connected to the fixed column, a circular hole is provided on the side of the clamping plate away from the fixed column, a clamping column fixedly installed with the pipe fitting is slidably connected in the circular hole, a circular hole is provided on the clamping plate, a sliding column is slidably connected in the circular hole, one end of the sliding column extends to the outside of the clamping plate and is fixedly installed with a connecting plate, the clamping plate is provided with a through hole penetrating the clamping column, and a locking column extending into the through hole is fixedly installed on the side of the connecting plate away from the sliding column.

[0013] Furthermore, the cross stabilization assembly includes a short cylinder fixedly mounted on the sleeves and pipe fittings on both sides, a rotating block is rotatably connected to the short cylinder, a fixed round block is provided on one side of the sleeve, a plurality of circumferentially distributed fixing rods are fixedly mounted on the side wall of the fixed round block, and one end of the fixing rod away from the fixed round block is fixedly mounted on the rotating block.

[0014] Furthermore, a circular hole is provided on one side of the short cylinder, a sliding column is fixedly installed in the circular hole, a clamping block is sleeved on the sliding column and is slidably connected to the circular hole, a compression spring sleeved on the sliding column is abutted between the clamping block and the inner wall of the circular hole, a sliding groove is provided on the inner wall of the circular hole and passes through the short cylinder, and a push button fixedly installed with the clamping block is slidably connected in the sliding groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Insert the vertical pipe into one of the circular holes of the pipe fitting, place the two arc-shaped abutment plates on both sides of the vertical pipe, and align the circular holes on the two arc-shaped abutment plates, put the second bolt into the circular hole, and rotate the second bolt to bring the two arc-shaped abutment plates closer to each other, and clamp the vertical pipe by bringing the two arc-shaped abutment plates closer to each other. Insert the two vertical pipes into the pipe fitting so that the vertical pipes on both sides remain in a stable state, pull the two pulling plates closer to each other, put the first bolt into the circular hole on the pulling plate, and rotate the first bolt to make the two pulling plates closer to each other. The movable plates are close to each other, and the two arc-shaped abutment plates fixed thereto are driven to approach each other through the mutual approach of the two pulling plates. Because the arc-shaped abutment plates are fixedly installed with the vertical pipes, the movement of the arc-shaped abutment plates will drive the vertical pipes on both sides to approach each other, causing the vertical pipes on both sides to be tightly fixed on the pipe fittings, making the scaffolding more solid and safer. By clamping the two arc-shaped abutment plates of the vertical pipes and the pulling plates that pull the two arc-shaped abutment plates together, the vertical pipes can be more stably fixed to the pipe fittings, and the multi-layer scaffolding can be safer when installed together.

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] In order to effectively illustrate the embodiments of the present invention, the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0030] See also Figure 1-7 The present invention provides a cantilever scaffolding jump-layer tie-in reinforcement device to solve the problem of instability during the construction of the cantilever scaffolding.

[0031] See also Figure 1 The embodiment of the present invention provides a cantilever scaffolding jump layer tie reinforcement device, comprising:

[0032] A transverse tube 1 is provided with a plurality of transverse tubes 1, and a plurality of connecting tubes 2 are fixedly installed between two adjacent transverse tubes 1. A plurality of vertical tubes 3 are provided on one side of the transverse tube 1, and the two vertical tubes 3 are arranged opposite to each other. A fixing assembly for fixing the two vertical tubes 3 is fixedly installed on one side of the transverse tube 1, and the two vertical tubes 3 are prevented from shaking back and forth by the fixing assembly.

[0033] Among them, the connecting pipe 2 is connected to the cross pipes 1 on both sides by welding. The connecting pipe 2 and the cross pipe 1 connected by welding are more secure, so that the connecting pipe 2 can withstand heavier weight without falling off, making the scaffolding more secure and safe.

[0034] See also Figure 1 , Figure 2 , Figure 3 , Figure 4The fixing assembly includes a pipe fitting 4 arranged on one side of the horizontal tube 1, one end of the horizontal tube 1 extends into the pipe fitting 4, the two vertical tubes 3 both extend into the pipe fitting 4, and both sides of the two vertical tubes 3 are abutted with arc-shaped abutting plates 10 for fixing them. Circular holes are opened on both sides of the arc-shaped abutting plates 10, and second bolts 20 for fixing the arc-shaped abutting plates 10 on both sides are slidably connected in the circular holes.

[0035] When the scaffold is built on the second floor, the vertical pipe 3 is inserted into one of the circular holes of the pipe fitting 4, the two arc-shaped abutment plates 10 are placed on both sides of the vertical pipe 3, and the circular holes on the two arc-shaped abutment plates 10 are aligned, the second bolt 20 is inserted into the circular hole, and the second bolt 20 is rotated to bring the two arc-shaped abutment plates 10 closer to each other, and the arc-shaped abutment plates 10 are brought closer to each other to clamp the vertical pipe 3. The two vertical pipes 3 are inserted into the pipe fitting 4 so that the vertical pipes 3 on both sides remain in a stable state. Of course, when the scaffold needs to be disassembled, the second bolt 20 is rotated to loosen the two arc-shaped abutment plates 10.

[0036] See also Figure 3 , Figure 4 A pulling plate 9 is fixedly installed on one side of the arc-shaped abutment plate 10, and a circular hole is opened on the side of the pulling plate 9 away from the arc-shaped abutment plate 10, and the central axes of the circular holes are located in the same plane. A first bolt 18 is slidably connected in the circular hole to fix the pulling plates 9 on both sides.

[0037] Specifically, pull the two pulling plates 9 closer to each other, put the first bolt 18 into the round hole on the pulling plate 9, rotate the first bolt 18, and move the two pulling plates 9 closer to each other. The two arc-shaped abutment plates 10 fixed thereto are driven closer to each other by the two pulling plates 9 approaching each other. Because the arc-shaped abutment plates 10 are fixedly installed on the vertical pipes 3, the movement of the arc-shaped abutment plates 10 will drive the vertical pipes 3 on both sides to approach each other, causing the vertical pipes 3 on both sides to be tightly fixed on the pipe fittings 4, making the scaffolding more solid and safe.

[0038] Of course, the length of the pulling plate 9 can be changed according to the length of the vertical pipe 3. When the length of the vertical pipe 3 is too high, a longer pulling plate 9 is used to fix the upper and lower vertical pipes 3 so that the upper and lower vertical pipes 3 cannot swing when used. The pulling plate 9 is connected to the arc-shaped abutment plate 10 by welding, and the pipe fitting 4 is connected by welding.

[0039] See also Figure 2 , Figure 4 , Figure 5A fixing plate is fixedly mounted on the pipe fitting 4 , threaded holes are provided on the fixing plate and the pipe fitting 4 , and a first threaded knob 13 abutting against the cross pipe 1 is threadedly connected in the threaded hole.

[0040] In detail, when the scaffolding needs to be fixed, the first threaded knob 13 is rotated forward, and the rotated first threaded knob 13 moves into the pipe fitting 4. The moved first threaded knob 13 presses against the cross tube 1 extending therein, and the pipe fitting 4 and the cross tube 1 are kept fixed by pressing against the cross tube 1 by the first threaded knob 13. If the scaffolding needs to be dismantled, the first threaded knob 13 is rotated reversely to move the first threaded knob 13 away from the cross tube 1. At this time, the cross tube 1 can be pulled out of the pipe fitting 4.

[0041] Preferably, a plurality of threaded holes distributed in a circular pattern are opened on one side of the pipe fitting 4, and a threaded knob that abuts against the cross tube 1 is threadedly connected to the threaded hole. The cross tube 1 can be better fixed by the plurality of threaded knobs, and the threaded knobs distributed in a circular pattern can apply a uniformly distributed force to the cross tube 1.

[0042] The stretching assembly includes a fixing column 11 fixedly mounted on the cross tube 1, a clamping plate 12 is slidably connected to the fixing column 11, a circular hole is provided on the side of the clamping plate 12 away from the fixing column 11, a clamping column 17 fixedly mounted to the pipe fitting 4 is slidably connected in the circular hole, a circular hole is provided on the clamping plate 12, a sliding column 19 is slidably connected in the circular hole, one end of the sliding column 19 extends to the outside of the clamping plate 12 and is fixedly mounted with a connecting plate 14, the clamping plate 12 is provided with a through hole penetrating the clamping column 17, and a locking column 16 extending into the through hole is fixedly mounted on the side of the connecting plate 14 away from the sliding column 19.

[0043] A stretching assembly is installed on the transverse tube 1 , and the fixing assembly on one side is stretched by the stretching assembly so that the fixing assembly is fixed on the transverse tube 1 .

[0044] See also Figure 1 , Figure 5 The stretching assembly includes a fixing column 11 fixedly mounted on the cross tube 1, a clamping plate 12 is slidably connected to the fixing column 11, a circular hole is provided on the side of the clamping plate 12 away from the fixing column 11, a clamping column 17 fixedly mounted to the pipe fitting 4 is slidably connected in the circular hole, a circular hole is provided on the clamping plate 12, a sliding column 19 is slidably connected in the circular hole, one end of the sliding column 19 extends to the outside of the clamping plate 12 and is fixedly mounted with a connecting plate 14, the clamping plate 12 is provided with a through hole penetrating the clamping column 17, and a locking column 16 extending into the through hole is fixedly mounted on the side of the connecting plate 14 away from the sliding column 19.

[0045] It is arranged that, when the cross tube 1 is inserted into the pipe fitting 4, the sliding clamping plate 12 makes the circular hole at one end of the clamping plate 12 sleeved on the clamping column 17, and the pipe fitting 4 is more secure by the clamping plate 12 and the clamping column 17 sleeved together, and will not fall off easily. Of course, if the clamping plate 12 is not fixed, the clamping plate 12 will fall off, so the connecting plate 14 is pressed downward, and the moving connecting plate 14 drives the connected locking column 16 to enter the circular hole on the clamping column 17, so that the clamping column 17 and the clamping plate 12 remain relatively fixed, and the sliding column 19 fixed on one side of the connecting plate 14 can support the connecting plate 14, so that the connecting plate 14 can move up and down smoothly.

[0046] The fixing column 11 is fixedly installed with the cross pipe 1 by welding. The fixing column 11 connected by welding is more stable and can pull the clamping column 17 on the other side without falling.

[0047] The vertical pipe 3 is sleeved with a sleeve 7, and a cross-stabilizing component is installed between the sleeve 7 and the fixing component, so that the two vertical pipes 3 will not shake left and right through the cross-stabilizing component.

[0048] See also Figure 1 , Figure 2 , Figure 6 The cross stabilization component includes a short cylinder 21 fixedly mounted on the sleeve 7 and the pipe 4 on both sides, and a rotating block 8 is rotatably connected to the short cylinder 21. A fixed round block 5 is provided on one side of the sleeve 7, and a plurality of circumferentially distributed fixed rods 6 are fixedly mounted on the side wall of the fixed round block 5. One end of the fixed rod 6 away from the fixed round block 5 is fixedly mounted on the rotating block 8.

[0049] Specifically, the two vertical tubes 3 on both sides are made more stable by multiple cross-placed fixing rods 6, and will not tilt to both sides, because the vertical tubes 3 on both sides and the upper and lower horizontal tubes 1 form a rectangular structure, and the rectangular structure is unstable and will tilt to one side to become a parallelogram, so the two fixed fixing rods 6 can increase the stability of the two vertical tubes 3, so that the vertical tubes 3 on both sides will not flip to the side due to slipping.

[0050] Among them, the fixing rod 6 is fixed to the fixing round block 5 by welding. The fixing rod 6 fixed by welding is more firm and can support the vertical pipes 3 on both sides more stably. Of course, the two upper short cylinders 21 are also connected to the sleeve 7 by welding, and the two lower short cylinders 21 are connected to the pipe 4 by welding. The short cylinders 21 connected by welding are more firm, so that when the fixing rod 6 pulls the short cylinder 21 through the rotating block 8, the short cylinder 21 will not fall off. Through the four fixed fixing rods 6, when two of the fixing rods 6 are broken, the vertical pipe 3 can still be supported.

[0051] See also Figure 7 A circular hole is provided on one side of the short cylinder 21, a sliding column 24 is fixedly installed in the circular hole, a clamping block 23 slidably connected to the circular hole is sleeved on the sliding column 24, a compression spring 25 sleeved on the sliding column 24 is abutted between the clamping block 23 and the inner wall of the circular hole, a sliding groove penetrating the short cylinder 21 is provided on the inner wall of the circular hole, a push button 22 fixedly installed with the clamping block 23 is slidably connected in the sliding groove.

[0052] It should be noted that a clamping groove is formed on the inner wall of the rotating block 8 , the clamping block 23 extends into the clamping groove, and the length of the sliding column 24 is shorter than the depth of the circular hole.

[0053] In detail, when the rotating block 8 is put on the short cylinder 21, it is necessary to pull the push button 22 to one side first. The moving push button 22 drives the clamping block 23 fixed with it to move, so that the clamping block 23 enters the round hole. At the same time, the moving clamping block 23 squeezes the compression spring 25. When the rotating block 8 is put on, release the push button 22. The compressed compression spring 25 pushes the connected clamping block 23 to one side, and the moving clamping block 23 moves into the clamping groove, so that the rotating block 8 is fixed on the short cylinder 21.

[0054] Of course, the plurality of fixing rods 6 are fixedly installed with the vertical pipes 3 on both sides so that the two vertical pipes 3 remain relatively fixed, and the fixing rods 6 are connected with the vertical pipes 3 by welding.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
