[0002] The existing Chinese utility model patent with the publication number CN219770135U and the name "A kind of marine eye plate support scaffolding convenient for efficient erection and dismantling" discloses that "the utility model includes a first eye plate 1 pre-installed and fixed on the main body of a ship or marine engineering structure, a first bracket 2 is movably sleeved on the outside of the first eye plate 1, a sleeve bevel 11 is provided at the sleeve joint of the first bracket 2 and the first eye plate 1, and the first bracket 2 and the first eye plate 1 are connected by a first bolt 3; when in use, the first bracket 2 is sleeved with the first eye plate 1 pre-installed and fixed on the main body of the ship or marine engineering structure, so that the sleeve bevel 11 is sleeved on the outside of the first eye plate 1, and then the first bracket 2 and the first eye plate 1 are connected by the first bolt 3 to avoid separation, and then the scaffolding board 7 and guardrail 8 are laid on the first bracket 2 to form a working platform for personnel to use for construction work". However, the pre-installed first eye plate needs to be cut off afterwards, and there are subsequent operations such as welding and painting, which is time-consuming and labor-intensive, with a long construction period and high production cost. Summary of the invention

[0003] The purpose of the present invention is to provide a method for building a ship segmented scaffolding which can shorten the construction period and reduce the production cost in view of the shortcomings of the prior art.

[0004] To achieve the above purpose, the technical solution adopted by the method for constructing a ship segmented scaffold of the present invention is:

[0005] A method for constructing a ship segmented scaffold comprises the following steps:

When installing, the U-shaped part is buckled on the upper edge of the surface to be constructed of the ship segment, and the locking bolt is screwed to squeeze the side wall of the upper edge, so that the ear plate is supported on the outer side of the upper edge of the surface to be constructed;

[0007] Step 2: Install the longitudinal beam: The longitudinal beam is formed by splicing a number of side panels from top to bottom. A number of second eyelets are opened on the side panels in a straight line and evenly arranged. During installation, the top of the uppermost side panel is connected to the ear panel by at least one bolt assembly, and the remaining side panels are connected end to end by a number of bolt assemblies from top to bottom and extend to the lower side of the surface to be constructed;

[0010] Step 5: Install the scaffolding board: Lay the scaffolding board on the same floor;

[0011] Step 6: Install the fence.

[0012] Preferably, the horse includes a cross bracing beam, one end of which is provided with a sleeve for installing a fence, and the other end is provided with a third eyelet, and the cross bracing beam is provided with a plurality of fourth eyelets around the third eyelet, and the third and fourth eyelets are used for connecting the side panels.

[0013] Preferably, the cross bracing beam is provided with a plurality of fifth eyelets for connecting the diagonal bracing rods, one side of the diagonal bracing rod is provided with a sixth eyelet for connecting the cross bracing beam, and the other side is provided with a plurality of seventh eyelets for connecting the side panels.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. There is no need to install PIECE (i.e., the first eye plate recorded in the prior art) on the surface to be constructed in advance. The scaffolding board can be supported directly by the clamp and the support leg. The side plate, the horse and the support leg are also installed by the bolt assembly.

The horses are evenly arranged on the longitudinal beam. During installation, since the angle between the upper part of the longitudinal beam and the vertical line is large, the horse installed in this area can refer to the installation method of Example 1; the angle between the lower part of the longitudinal beam and the vertical line is small, and the horse installed in this area can refer to the installation method of Example 2;

[0057] Step 5: Install the scaffolding board: Lay the scaffolding board on the same floor;

[0058] Step 6: Install the fence.

[0059] The present invention is assembled from a clamp, a longitudinal beam, a support leg, a horse and other devices into a temporary frame attached to the surface to be constructed.
