Description

Technical Field

[0001] The invention relates to the technical field of scaffolding, in particular to a scaffolding erection method. Background Art

[0002] The multi-layer thin plate deck section edge protection railing is used to prevent the multi-layer deck edge from falling from high altitude. It is used in the two stages of section assembly construction and dock loading construction. There are the following problems in its use:

[0003] First, during the assembly construction phase, due to the excess marking and cutting operations on the edge of the thin deck, and considering that the guardrails are tightened with bolts using chucks and the thin deck edge, the edge guardrails need to be temporarily removed before the excess operations, resulting in the absence of safety guardrails when personnel work on the edge of the deck during the excess operations, creating a risk of falling from the edge of the multi-layer deck. After the excess operations are completed, the edge guardrails need to be restored in time to avoid the risk of falling from the edge of the multi-layer deck.

[0004] Second, during the dock-mounted construction phase, for the total section currently being hoisted and mounted, when it is docked with the total section that has been pre-loaded on the dock, it is necessary to remove the side protective railings of the two total sections while the total section is hoisted but not unhooked and the two total sections are close to docking. Considering safety factors, the side protective railings of the two total sections cannot be removed in advance, resulting in the scaffolding work being removed when the total section is hoisted and before it is hoisted into place, which increases the hoisting operation time.

[0005] Third, if Figure 1 As shown, the existing guardrail tooling usually uses a clamp that is commonly used for thick plate structure ships, which causes the clamp to fit poorly with the deck edge, resulting in poor stability of the guardrail and weak protective effect, and there is a risk of high-altitude falling from the multi-layer deck edge. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a scaffolding erection method, which solves the problems mentioned in the above background.

[0007] The present invention provides the following technical solution: a scaffolding erection method, comprising the following steps:

[0008] Step S1: Install the fixed scaffolding horse. In the reverse construction stage of the thin plate segmented deck, a distance position is reserved from the edge of the thin plate segmented deck, a straight line mark is made, and the fixed scaffolding horse installation position is divided, and the fixed scaffolding horse is installed;

[0009] Step S2: installing a docking scaffolding horse, installing a docking scaffolding horse at the lower end of the column of the guardrail scaffolding, and connecting the docking scaffolding horse to the fixed scaffolding horse;

[0010] Step S3: assembling the guardrail scaffolding, measuring the length of the thin plate segmented deck, and assembling the crossbars of the guardrail scaffolding onto the columns of the guardrail scaffolding;

[0011] Step S4: installing the footboard of the guardrail scaffolding;

[0012] Step S5: After the thin plate segmented deck is turned over, a scaffolding is finally formed.

[0013] Preferably, in step S1: the fixed scaffolding horse is welded to the thin plate segmented deck, the fixed position of the fixed scaffolding horse is on a pre-made straight line mark, and the fixed position of the fixed scaffolding horse is aligned with the position of the deck longitudinal bone on the thin plate segmented deck.

[0014] Preferably, in step S2: the docking scaffolding horse is welded to the bottom end of the column, and the docking scaffolding horse is installed to the surface of the fixed scaffolding horse using bolts.

[0015] Preferably, in step S4: a toeboard is installed on the thin plate segmented deck, and the toeboard is located on a side of the guardrail scaffolding away from the fixed scaffolding horse, and the toeboard is in close contact with the surface of the column.

[0016] Preferably, the footboard and the thin plate segmented deck are intermittently welded to reduce deformation of the thin plate during welding and removal, and reduce the workload of removing the footboard.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, during the reverse construction stage of the thin plate segmented deck, fixed scaffolding horses and docking scaffolding horses are respectively installed, and the vertical poles and horizontal poles of the assembled guardrail scaffolding are assembled. The scaffolding is pre-erected in a reversed manner in sections, and the safety protection scaffolding can be used immediately after the sections are turned over, so as to avoid the situation where there is no guardrail scaffolding on the thin plate segmented deck, and reduce the risk of high-altitude fall when installing the guardrail scaffolding.

[0019] 2. The present invention welds the fixed scaffolding horse to the thin plate segmented deck, and uses bolts to fix the fixed scaffolding horse and the butt scaffolding horse to reduce the shaking of the edge protection railing. The fixed scaffolding horse is aligned with the longitudinal bone of the thin plate segmented deck for welding, which improves the overall strength and stability of the scaffolding horse and the scaffolding. Intermittent welding is adopted for the thin plate segmented deck and the butt scaffolding horse and the thin plate deck, which reduces the deformation of the thin plate during welding and removal and reduces the workload of scaffolding horse removal.
