Description

Technical Field

[0001] The invention belongs to the technical field of erecting a construction platform for a building project, and in particular provides a method for quickly erecting and dismantling a construction platform on a slope. Background Art

[0002] At present, construction work faces many operations on slopes. For example, the slope of the foundation pit is often a slope, and the slope of the roadbed is often a slope, etc. These slopes have a certain height. Operations on the slope, such as slope masonry and slope protection, require the construction platform to facilitate the construction of workers. Because it is a slope, the frame located at the slope is not easy to bear force, and it is inconvenient to set up the construction frame. The general practice is that workers set up simple block walls along the slope, and set up springboards between the walls as construction platforms. This method is time-consuming and wastes a lot of masonry materials and manpower. Summary of the invention

[0003] The purpose of the present invention is to provide a method for quickly erecting and dismantling a slope surface construction platform, which mainly uses self-made components and pipes to erect a construction frame on the slope surface, and sets up a springboard on the frame to form a construction platform for workers to construct. The frame is quickly erected and dismantled, reducing the waste of blocks and labor input in general practices, as well as the time for building simple walls, improving construction speed, and saving labor costs, material costs and construction period costs.

[0004] The present invention uses self-made components and frame pipes (self-made components include bottom components 1, top components 2, slope components 3, and self-made frame pipes are frame pipes 4) to build a construction frame at the slope surface, and set up a springboard on the frame to form a construction platform. It includes installing the bottom component 1; vertically installing the frame pipe 4 on the bottom component 1; installing the top component 2 on the top of the frame pipe 4, with the right angle facing the slope surface; installing the slope component 3 in line with the slope surface 7, and being in the same horizontal plane as the top component 2; connecting the top component 2 and the slope component 3 through the frame pipe 4; repeating the above steps to build multiple rows of frames, and using the frame pipe 4 to connect the top component 2 horizontally to form a whole frame; laying a springboard 6 on the top surface of the built frame to form a construction platform; adjusting the height of the vertical frame pipe 4 and the length of the frame pipe 4 facing the slope surface to build a construction platform that is suitable for the entire height range of the slope surface; after the construction of the work content on the slope surface is completed, the construction platform is dismantled in reverse according to the above steps. The specific steps are as follows:

[0005] (1) Install the bottom member 1 on the horizontal ground 8 at the bottom of the slope surface 7;

[0006] (2) Install the pipe rack 4 vertically on the bottom member 1 and tighten it with M16 high-strength bolts. The height of the pipe rack 4 is determined according to the height of the pre-erected construction platform;

[0007] (3) Install the top member 2 on the top of the rack pipe 4 and tighten it with M16 high-strength bolts, with the right-angled opening of the top member 2 facing the slope surface;

[0008] (4) Install the slope member 3 in line with the slope surface 7 so that it is on the same horizontal plane as the top member 2;

[0009] (5) The top member 2 and the slope member 3 are connected by the frame pipe 4, which are both tightened with M16 high-strength bolts. If the length of the frame pipe 4 is insufficient, it can be lengthened by right-angle fasteners;

[0010] (6) Repeat steps 1 to 5 to erect multiple rows of frames, and use frame pipes 4 to connect the top members 2 horizontally, and tighten them with M16 high-strength bolts to form a whole frame; the erection spacing and connection method are as follows:

[0011] The spacing between each row of individual frames is 2m, and the top members 2 are connected transversely by frame pipes 4, so that each row of frames forms a whole; when the vertical and transverse frame pipes 4 are not long enough, they can be lengthened by right-angle fasteners. If the overall length of the frame pipes 4 extending to the slope surface exceeds 6m, a reinforced vertical pole (with a pad at the bottom) can be provided in the middle through ordinary frame pipes and bowl fasteners, and each row of frames can be connected transversely in the middle;

[0012] The depth of the rack pipe 4 extending into the self-made components (bottom component 1, top component 2, slope component 3) is 250 mm, and an M16 high-strength bolt hole is drilled 150 mm inward from the end of the rack pipe 4.

[0013] All the rack pipes 4 and the self-made components are connected by M16 high-strength bolts 5. The length of the M16 high-strength bolts 5 is adjusted according to different connection parts so that the connection parts can be tightened. The screws at the connection parts are wire-free to better transmit the force.

[0014] (7) A springboard 6 is laid on the top surface of the erected frame to form a construction platform.

[0015] (8) Adjust the height of the pipe rack 4 in step (2) and the length of the pipe rack 4 in step (5) to build a construction platform that is suitable for the entire height range of the slope surface.

[0016] (9) After the work on the slope is completed, the construction platform should be dismantled in reverse order according to steps (1) to (8).

[0017] The bottom member 1 in the present invention is formed by cross-welding two steel plates with a length of 600 mm, a width of 200 mm and a thickness of 2 mm (one steel plate at the cross position is disconnected), and a flat cross base is formed after welding. A DN50 welded steel pipe with a height of 300 mm is welded in the middle of the cross-intersection position, and an M16 high-strength bolt hole is drilled 100 mm inward from the end of the steel pipe.

[0018] In the present invention, the top member 2 is welded by two DN50 welded steel pipes with a length of 300 mm and one DN50 welded steel pipe with a length of 700 mm, and the other two DN50 welded steel pipes with a length of 300 mm are welded in the middle of the DN50 welded steel pipe with a length of 700 mm to form a right angle. M16 high-strength bolt holes are drilled 100 mm inward at the four steel pipe ports of the welded top member 2.

[0019] The slope component 3 of the present invention is welded into a channel steel shape by a steel plate of 500 mm in length, 200 mm in width and 2 mm in thickness and two steel plates of 500 mm in length, 300 mm in width and 2 mm in thickness, and an M16 high-strength bolt hole is drilled 100 mm inward from the notch in the middle of the homemade channel steel.

[0020] In the present invention, the rack pipe 4 is made of ordinary rack pipe, and the depth of the rack pipe 4 extending into the self-made components (bottom component 1, top component 2, slope component 3) is 250mm, and an M16 high-strength bolt hole is drilled 150mm inward from the end of the rack pipe 4. All rack pipes 4 and self-made components are connected by M16 high-strength bolts 5. The length of the M16 high-strength bolts 5 is adjusted according to different connection parts so that the connection parts can be tightened. The screw rods at the connection parts are wire-free to better transmit the force.

[0021] In the present invention, the spacing between each row of frames is 2m, and the rows are connected as a whole at the ends through the top member 2 and the frame pipe 4. If the vertical and horizontal frame pipes 4 are not long enough, they can be lengthened by right-angle fasteners. If the overall length of the frame pipe 4 extending to the slope surface exceeds 6m, a reinforced vertical pole (with a pad at the bottom) can be set in the middle part through ordinary frame pipes and bowl fasteners to connect each row of frames horizontally.

[0022] The method of the present invention mainly comprises prefabricated components (bottom component 1, top component 2, slope component 3) and frame pipe 4 (ordinary frame pipe) for rapid installation and connection through M16 high-strength bolts 5 to form an integral and firm frame, and laying a springboard 6 on the frame to form a construction platform, which is convenient for workers to work on the slope surface. The frame height and the distance from the slope surface can be adjusted by adjusting the length of the frame pipe 4, so as to form a construction platform suitable for the full height range of the slope surface, and the slope component 3 is fitted with the slope surface of different angles, and the frame pipe 4 can be rotated with the high-strength bolt as the axis to maintain the level, so as to facilitate the construction platform frame.

[0023] The beneficial effects of the present invention are:

[0024] 1. Advancedness: It is simple to make and easy to assemble and disassemble.

[0025] 2. Necessity: It can quickly build a construction platform on the slope surface so that workers can carry out construction work.

[0026] 3. Cost saving: This method is quick to assemble and disassemble, speeds up construction, and saves material costs, labor costs and construction period costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to make the method of the present invention more clearly understood, the implementation process of the method is briefly described below.

[0033] 1. Make bottom member 1, top member 2, slope member 3, cut frame pipe 4 to adapt to the pre-erected frame height and distance from the slope, and drill M16 high-strength bolt holes at the ends of all members and frame pipe connections.

[0034] 2. Install the bottom member 1 on the horizontal ground 8. The bottom member 1 is cross-shaped, which can well bear the force transmitted from the upper steel pipe, prevent the rack pipe from sinking when standing directly on the ground, and has good anti-overturning performance.

[0035] 3. Install the frame pipe 4 on the bottom member 1 and tighten it with M16 high-strength bolts.

[0036] 4. Install the top member 2 on the rack pipe 4, with the right angle facing the slope surface, and tighten it with M16 high-strength bolts. The top member 2 can quickly and firmly connect the horizontal and vertical rack pipes.

[0037] 5. Install the slope component 3 in accordance with the slope surface 7. The slope component 3 can closely fit the slope surfaces at different angles and transmit the force transmitted from the rack pipe, thereby preventing the rack pipe from sinking directly on the slope surface and damaging the slope surface.

[0038] 6. The top member 2 and the slope member 3 are connected through the frame pipe 4, which are tightened with M16 high-strength bolts. When the frame pipe 4 is not long enough, it can be lengthened with right-angle fasteners. When the frame pipe 4 is longer than 6 meters, a reinforced vertical pole (with a pad at the bottom) can be installed in the middle part through ordinary frame pipes and bowl fasteners, and each row of frames can be horizontally connected in the middle part to enhance stability. Use M16 high-strength bolts to connect the frame pipe 4 and the slope member 3. When the slope member 3 is fitted with slopes of different angles, the frame pipe 4 can be rotated with the M16 high-strength bolts as the axis to maintain levelness and stability, which is convenient for setting up a construction platform.

[0039] 7. Repeat the above steps to build multiple rows of frames, with a spacing of 2m between each row of frames, and use frame pipes 4 to connect the top components 2 horizontally, and tighten them with M16 high-strength bolts to form a whole frame.

[0040] 8. Lay a springboard 6 on the top surface of the erected frame to form a construction platform.

[0041] 9. Adjust the height of the pipe 4 in the end upright and the length of the pipe 4 extending to the slope surface so as to set up a construction platform that adapts to the entire height range of the slope surface.

[0042] 10. After the overall construction of the work on the slope is completed, the construction platform shall be dismantled in reverse order according to the above steps.
