Description

Technical Field

[0001] The invention relates to the technical field of ship and ocean engineering construction, and in particular to a non-welding rooting and fixing method for a segmented outer plate scaffold. Background Art

[0002] During shipbuilding, painting is often required after the completed sections are completed, depending on the ship's performance and operating environment. However, due to the structural form of the hull's non-structural surface and the construction environment, erecting and dismantling scaffolding in these non-structural areas of the curved section remains a challenge. These non-structural areas typically lack anchoring points for scaffolding installation. To ensure safety during construction, reliable anchoring points are essential for erecting and dismantling scaffolding on the curved section.

[0003] Existing painting operation platforms mainly use welded rooting fixing points to build ordinary steel pipe scaffolding. When using welded rooting points to build ordinary steel pipe scaffolding, the heat-affected zone of the weld causes damage to the inner and outer coatings and the parent material of the outer plate. The installation, welding, and repair work of the rooting points are costly, with a long construction period and a large workload. The high-altitude operation of the rooting points is risky and inefficient, posing a safety hazard and affecting the entire construction cycle of the ship. In addition, the tedious installation, removal, grinding and repair of existing welded rooting points can no longer meet the needs of efficient development of shipyards. Their reuse rate is low, resulting in material waste. In addition, from the perspective of ship aesthetics, the use of welded rooting points should be avoided in principle. In addition, there are also magnetic rooting fixing points, whose operation method is subject to factors such as the environment, human operation, and insufficient bearing capacity, and are generally not used.

[0027] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0028] A non-welding rooting and fixing method for a segmented outer plate scaffold is applied to a rooting and fixing matching device 3 adapted to a protruding structure 2 of a hull outer plate, combined with Figures 4 to 6As shown, the rooting and fixing matching device 3 includes a connecting plate 31 and a limiting plate 32, wherein the connecting plate 31 is provided with a hanging hook groove 33 and a through hole 34 by CNC cutting, the hanging hook groove 33 is open, and its inner end side is adapted to the hook end of the above-mentioned hull outer plate protruding structure 2; the limiting plate 32 is welded and fixed to the inner edge of the above-mentioned hanging hook groove 33 facing away from the hook end, and is relatively perpendicular to the connecting plate 31, and the transverse width of the limiting plate 32 is greater than the thickness of the connecting plate 31; the aperture setting size of the through hole 34 can meet the use space requirements of the standard scaffolding steel pipe (Φ48×3.5mm or Φ51×3mm).

[0029] Reference Figures 1 to 3 As shown, the non-welding rooting and fixing method specifically includes the following steps:

[0030] Step S1, design and manufacture rooting and fixing supporting device 3. First, determine the specifications of rooting and fixing supporting device 3 according to the form of hull outer plate protruding structure 2 in the pre-erected area, and then manufacture it in a unified standard to meet various construction requirements and facilitate the setting of rooting points.

[0031] The hull outer plate protruding structure 2 on the above-mentioned hull outer plate non-structural surface 1 is in the shape of an elongated strip, and the bottom of its outer end edge protrudes downward to form a barbed hook structure; the hanging hook groove 33 in the above-mentioned rooting and fixing matching device 3 is adapted thereto.

[0032] Step S2: Install the rooting and fixing device 3. Multiple rooting and fixing devices 3 are provided according to actual operational requirements. These devices are rationally arranged according to scaffolding erection standards and freely slide into the corresponding hull plating protruding structure 2 from one end to complete the pre-installation layout without welding and fixing. The hook groove 33 is adapted to engage the hull plating protruding structure 2, and the two are firmly connected by a limit plate 32. The limit plate 32 is placed above the hull plating protruding structure 2, on the opposite side of its raised barb-shaped structure, and can withstand opposing pulling forces to prevent the rooting and fixing devices 3 from rotating. It also prevents the rooting and fixing devices 3 from detaching from the hull plating protruding structure 2, ensuring a stable and reliable rooting point.

[0033] Step S3, erecting scaffolding. With the aid of the above-mentioned rooting and fixing matching device 3, the scaffolding steel pipes are freely combined and erected to adapt to the curved working area of ​​the non-structural surface 1 of the hull outer plate; first, the transverse standard scaffolding steel pipe 4 is passed through the through hole 34 on the above-mentioned connecting plate 31 for installation, and the steel pipe fasteners 8 are installed on the transverse standard scaffolding steel pipes 4 on both sides of the connecting plate 31 in the single rooting and fixing matching device 3 for fixed connection. The main node of the steel pipe fastener 8 is less than or equal to 300mm away from the plane of the connecting plate 31 to limit the lateral movement of the transverse standard scaffolding steel pipe 4 and ensure the strength and safety of the overall working platform; then the transverse standard scaffolding steel pipe 4 is firmly connected and fixed with the longitudinal standard scaffolding steel pipe 5 and the vertical standard scaffolding steel pipe 6 through the steel pipe fastener 8 in sequence, and the erection of the overall working platform is gradually completed according to the scaffolding erection requirements; then the scaffolding board 7 is placed on the corresponding scaffolding steel pipe for movement by the operators.

[0034] Step S4: Dismantle the scaffolding. After the painting work is completed, the scaffolding platform is dismantled and the materials are sorted and organized according to the scaffolding steel pipe erection and dismantling operation sequence and construction standards. The rooting and fixing device 3 is then removed and recycled for reuse. Similar areas on a single ship can be reused. The reserved painting area at the connection point with the hull structure is then quickly completed according to the painting repair work requirements to achieve a complete and beautiful painting.

[0035] As a technical solution of another embodiment of the present invention, a rotatable universal joint bearing inner sleeve is installed in the through hole 34 on the connecting plate 31 in the above-mentioned rooting and fixing supporting device 3 to facilitate the adjustment of the setting direction of the horizontal standard scaffolding steel pipe 4. The overall installation direction is determined by the erection method, and then the supporting devices are arranged in place in sequence.

[0036] The above-mentioned entire construction and erection method has positive significance for improving the efficiency of shipbuilding. The efficient operation mode with the help of auxiliary components is in line with the development direction of the enterprise and can enhance the competitive advantage of the enterprise.

[0037] Finally, the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to preferred cases, those skilled in the art should understand that the technical solutions of the present invention may be modified, changed, added to or replaced by equivalents without departing from the spirit and substantial scope of the technical solutions of the present invention, and all of these should be included in the scope of protection of the present invention.
