Description

Technical Field

[0001] The invention relates to the technical field of telescopic socket-and-spigot type disc buckle scaffolds, in particular to a novel processing technology of a fixed-length telescopic socket-and-spigot type disc buckle scaffold. Background Art

[0002] Conventional scaffolding utilizes fixed-length rods with clips at each end and chucks at the transition points. However, for external scaffolding, since the rod lengths are fixed to a fixed module, the spacing between the vertical rods is limited by the standard horizontal tie rod length and can only be multiples of 300mm. However, during actual construction, when the vertical rods are arranged according to the building's external dimensions and shape, there will always be a span in some areas that does not conform to the standard horizontal rod length module. This situation is very common in external scaffolding construction, but there are currently no supporting components for the clip rods, and no relevant specifications clarify the specific construction measures for such locations.

[0003] The length of the horizontal tie rods in existing socket-and-spigot-type, disc-type steel pipe supports cannot be adjusted, resulting in a mismatch between the actual vertical distance of the frame and the modulus of the horizontal tie rods of the disc-type support during construction. To address this issue, we have introduced an improved, adjustable disc-type horizontal tie rod system. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a new type of fixed-length telescopic socket-type buckle scaffolding processing technology, which can solve the construction problem that the actual vertical distance of the general frame is inconsistent with the fixed-length horizontal rod module of the buckle frame.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a new type of fixed-length telescopic socket-type disc buckle scaffolding processing technology, the innovation of which lies in: the specific processing technology is as follows:

[0006] S1: Material preparation: Materials include horizontal rods for the buckle rack, steel pipes, bolts with tail rings, nuts, welding rods, welding machines, abrasive cutting machines, bench drills, and drill bits;

[0007] S2: Cutting of the horizontal rod of the buckle frame: Use a grinding wheel cutter to cut the horizontal rod of the buckle frame on site. The cut should be 80mm away from the end of the rod. When cutting, keep the cut perpendicular to the axis of the rod and the cut surface flat. After cutting, the horizontal rod of the buckle frame is divided into a main rod and a secondary rod. The length of the main rod is greater than that of the secondary rod.

[0008] S3: Drilling holes for the horizontal rod of the disc-shaped rack: On the main rod of the disc-shaped rack, drill two φ25 circular holes at 50mm and 80mm away from the cut position respectively using a bench drill. The two circular holes are vertically distributed along the cross-section center of the main rod;

[0009] S4: Nut welding: Tighten the bolt with the tail ring until the end protrudes 10mm from the nut. Insert the bolt into the round hole drilled on the main rod. Adjust the bolt to the center of the round hole by moving it horizontally, and make the nut close to the outer wall of the main rod. After confirming that the screw is in the correct position, spot weld the nut and the main rod to initially fix it. Rotate the screw again to ensure that the thread rotates smoothly and there is no biting with the hole wall. After confirming that everything is correct, remove the bolt and continue welding along the circumference of the nut to completely fix the nut on the main rod.

[0010] S5: Telescopic sleeve welding: Insert the steel pipe into the auxiliary rod cutout by 15-20mm, and keep the sleeve and auxiliary rod axial positions parallel. Apply spot welding at the gap between the two pipes for preliminary fixation. Check again whether the axial positions of the two pipes are coaxial by plane rolling or angle ruler measurement, and make corrections. After confirmation, weld the entire circumference of the gap between the two pipes. When welding, weld in four sections along the annular symmetrical position to prevent thermal stress from causing deformation of the pipe fittings and dislocation of coaxiality. After welding is completed, remove the welding slag in time and check the fullness of the weld.

[0011] S6: Assembly of the telescopic rod: First, screw the bolt with the tail ring into the welding nut of the main rod, and check whether the bolt rotates smoothly. If there is any thread jamming, the screw should be withdrawn, and iron filings, welding slag and other debris in the thread should be cleared. Try to tighten the bolt again. If there is still thread jamming, drip lubricating oil into the thread, insert a short pry bar into the bolt tail ring, gently tighten the bolt about half a thread, and then return it to its original position. Repeat this process until the thread rotates completely and smoothly; fully insert the auxiliary rod with the steel pipe welded into the main rod, and rotate the bolt so that the end of the bolt presses against the outer wall of the steel pipe on the auxiliary rod to ensure that the steel pipe cannot slide freely;

[0012] S7: On-site adjustment of fastening bolts: When using on-site, first use a set of adjustment rods to pre-adjust the length of the telescopic rod according to the actual size of the non-standard vertical pole spacing on site, and after trial installation on the first step of the buckle frame, use a short pry bar to tighten the tail ring bolts, remove the buckle pins at both ends, remove the adjustable rod as a basis for batch adjustment, and adjust the length of other rods to the same standard length for standby use;

[0013] S8: Buckle connection: Connect the adjustable tie rods with pre-adjusted lengths by buckling and latching them in the normal operation mode of the buckle scaffolding; then use a short pry bar to insert the tail ring to check the tightness of the bolts one by one to ensure that there is no loose thread slippage;

[0014] S9: Bolt re-tightening inspection: After the adjustable tie rod is connected to the pankou scaffolding, a short pry bar should be inserted into the tail ring to check the tightness of the bolts one by one to ensure that there is no looseness or thread slippage;

[0015] S10: Facade effect inspection: Observe with the naked eye from a distance or use a theodolite to observe whether the distance between the vertical poles is vertical and equidistant. If there is an obvious error, remove the adjustment rod, adjust the length of the telescopic rod, tighten the bolts and reinstall it until the vertical poles are vertical and the distance between them is consistent.

[0016] Furthermore, in S6, the external welded portion of the pipe is locally rust-proofed using anti-rust paint and silver paint; and the finished product is stored for later use.

[0017] Furthermore, in order to ensure that the spacing between non-standard vertical poles is consistent in S7, when using the adjustable pull rods, it is not possible to connect the buckles one by one and then tighten the bolts. Be sure to pre-adjust and tighten the telescopic sleeve according to the above steps to make the lengths of all adjustable pull rods in the same part consistent.

[0018] The advantages of the present invention are:

[0019] 1) The present invention reasonably considers the turnover use of the adjustable horizontal rod, thereby improving the utilization rate of construction resources; when processing the adjustable horizontal rod, it can be cut and cut by locally sourced materials according to the actual situation on site and the module requirements, which is convenient to operate; it makes full use of old steel pipes, improves the material utilization rate while meeting the quality requirements, and has good energy-saving benefits; since the connection method between the adjustable horizontal rod and the vertical rod still adopts the original buckle pin, the rod remains consistent with the overall appearance of the external frame after installation.
