The T-shaped chuck includes a clamping plate with a T-shaped opening on its cross-section. One side of the T-shaped opening has a beveled angle. A short sleeve is provided at the lower end of the clamping plate, and a fastening tapered bolt is provided inside the short sleeve. The fastening tapered bolt is connected to the short sleeve by threads. The other end of the clamping plate has a nested square stop block. The second spring pin and the second adjusting bolt form a web clamping system for clamping the profile. The main body of the construction operation platform is an aluminum alloy platform with a round bean-shaped anti-slip pattern on its surface. Lifting lugs are provided on both sides of the aluminum alloy platform. A protective railing is provided on the outer side of the aluminum alloy platform, and a corrugated rubber strip is provided on the inner edge of the aluminum alloy platform.

The protruding shaft is a cylinder with a diameter 1 mm smaller than the end face opening of the first spring pin cylinder. The circular liner plate is a flat circular body with a diameter 1 mm smaller than the inner diameter of the first spring pin cylinder.

[0009] In a further preferred embodiment, the U-shaped plate groove is 100 mm long and 200 mm high, and has two vertical pulleys with a diameter of 40 mm inside, the vertical pulleys being 10 mm thick.

[0010] In a further preferred embodiment, the U-shaped plate groove is provided with a handle for lifting or suspending the sliding U-shaped module.

[0011] A further preferred technical solution is that the clamping plate is used for fixing and fastening both T-shaped profiles and bulb flat steel profiles.

[0012] A method for improving the efficiency of a device for enhancing the efficiency of ship section construction includes the following steps:

[0013] Step 1: Fabricate a device for improving the efficiency of ship section construction, the components of which include a sliding U-shaped module, a T-shaped clamp, and a construction operation platform;

[0014] Step 2, laying the base panels on the jig: After the segmented base panels are laid on the jig and the assembly is finished, install 4 sliding U-shaped modules at the uppermost edge of the segment.

[0015] Step 3: Place the construction operation platform on the flat area of ​​the board on the jig;

[0016] Step 4: The device is flexibly connected, with the construction area as the anchor point, and the hand chain hoist and the anchor hook of the sliding U-shaped module are flexibly connected to the construction operation platform through steel wire rope and shackle.

[0017] Step 5: The construction operation of transverse weld seam welding is carried out by adjusting the front and back position by rotating the hexagonal nut end, thereby indirectly adjusting the compression degree of the first spring, controlling the force of the steel pulley on the transverse U-shaped plate pressing against the edge of the segment plate, moving the sliding U-shaped module to the required position, tightening and loosening the hand chain hoist, moving the construction operation platform laterally, and pulling the construction operation platform to the construction height position by tightening the hand chain hoist, and the workers on the construction operation platform carry out the construction operation of transverse weld seam welding of the main plate.

[0019] Step 7: The welding of the panels and the installation of the profiles for the segmented facade are completed.

[0020] In a further preferred technical solution, in step 5, before moving the sliding U-shaped module, the first adjusting bolt is loosened to reduce the clamping force of the first spring. Under the tension and relaxation force of the first spring, the steel pulley can move over the protrusions on the surface of the steel plate.

[0021] In a further preferred technical solution, in step 6, two T-clamps simultaneously fix a profile. A T-clamp is fitted at each end of the profile. By tightening the conical bolts and the web clamping system, the T-clamps clamp the profile.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and specific examples, but this should not be construed as limiting the scope of protection of the present invention.

[0035] This invention provides a device for ship section facade construction, applied in the section construction phase, such as... Figure 1 The device shown includes a plate edge sliding module 19, a T-shaped clamp 20, and a construction operation platform 21.

[0036] like Figure 2As shown, the sliding U-shaped module 19 has a T-shaped structure. The entire sliding U-shaped module 19 includes two horizontal U-shaped plates 1. The length of each horizontal U-shaped plate 1 is 150 mm. It is equipped with two steel pulleys 3 inside. The diameter of the steel pulleys 3 is 60 mm and the thickness is 10 mm. Two horizontal U-shaped plates 1 and one vertical U-shaped plate 8, along with two triangular elbow plates 2, form an inverted T-shaped structure. The U-shaped plate groove 8 is 100 mm long and 200 mm high, and contains two vertical pulleys 10 with a diameter of 40 mm and a thickness of 10 mm. A handle is provided on the U-shaped plate groove 8, and anchor hooks are provided on the triangular elbow plates 2, primarily for connecting and fixing the construction operation platform and T-shaped clamps. The U-shaped plates 1 and triangular elbow plates 2 are not directly connected, but rather indirectly and flexibly connected through a first spring pin cylinder 4 below the triangular elbow plates, a nested sliding convex shaft 5, forming a flexible support system. This system can clamp the inner and outer side walls of the plate, forming a sliding and clamping tension adjustment system. The nested sliding convex shaft 5 includes a protruding shaft combined with a larger circular backing plate, forming a stepped shape. The protruding shaft is a cylinder with a diameter 1 mm smaller than the end face opening of the first spring pin cylinder 4. The larger circular backing plate is a flattened circular body with a diameter 1 mm smaller than the inner diameter of the first spring pin cylinder 4. One end of the flat, round shape is pressed into contact with the first spring 6. The first spring pin cylinder 4 has an internal thread, and the outer side of the first spring 6 is the first adjusting bolt 7. One end of the first adjusting bolt is a hexagonal nut, and the other end is a flat, round ring with an external thread around its circumference. This external thread matches the inner diameter of the first spring pin cylinder 4. Tightening the hexagonal nut allows the first adjusting bolt to move within the first spring pin cylinder 4. By rotating the nut end, the forward and backward position can be adjusted, thereby indirectly adjusting the degree of pressing of the first spring pin cylinder 4. This controls the force of the steel pulley 3 on the transverse U-shaped plate 1 pressing against the edge of the segmented plate, thus affecting the strength of the compression force of the first spring. The steel pulley 3 can be used to move the sliding U-shaped module against the inner and outer walls of the plate. The transverse U-shaped plate 1 and the first spring pin cylinder 4 are reinforced and connected by a triangular elbow plate 2. The triangular elbow plate 2 is equipped with a fixed anchor hook for connecting the steel wire rope and has a symmetrical structure about the transverse U-shaped plate groove 8.

[0037] like Figure 3 As shown, the T-type chuck 20 includes a steel chuck 11, which has a 20mm round hole for connecting wire ropes and shackles. The T-type chuck 20 has T-shaped and single-sided ball-head cutouts, which can be used to fix both T-shaped profiles and flat steel. One end of the T-type chuck is provided with a short sleeve 13, and a fastening tapered bolt 12 is provided inside the short sleeve. The fastening tapered bolt 12 inside the short sleeve is connected by threads. The other end is provided with a second spring pin sleeve 22, which, together with the second adjusting bolt 24, the second spring 23, and the nested square stop block 14, forms a clamping system that can be used to clamp the web of the profile.

[0038] like Figure 4 As shown, the construction operation platform 21 is equipped with a 2m * 1.5m rectangular aluminum alloy platform 18. A 30mm thick corrugated rubber strip 17 is installed on the inner side of the platform to improve stability and prevent swaying when the platform rests against the inner side of the segmented plates. An 800mm high guardrail is installed above the aluminum alloy platform 18 to protect the safety of construction personnel and prevent tools from falling. Lifting lugs 16, each 1000mm long, are installed on both sides of the aluminum alloy platform 18. Each lifting lug 16 has a 20mm round hole for connecting to shackles and wire ropes.

[0039] This invention applies a construction method for a ship section facade construction device, comprising the following steps:

[0040] Step 1: Install sliding U-shaped modules 19 on the uppermost edge of the segment after the base panel has been laid. Before construction, lay the main plate of the segment base surface on the jig surface and mark the lines according to conventional process. When the main plate is laid and the assembly is finished, install 4 sliding U-shaped modules 19 of the present invention on the upper edge of the uppermost edge of the main plate.

[0041] Step 2: Place the construction platform on the flat part of the board;

[0042] Step 3: Using the sliding U-shaped module 19 as anchor points, use shackles, wire ropes, and hand-operated hoists to connect the lifting lugs 16 of the construction operation platform to the anchor hooks on the triangular elbow plates 2 of the four sliding U-shaped modules 19.

[0043] Step 4: Pull the construction operation platform to the construction area of ​​the vertical operation by tightening the hand chain hoist; pull the construction operation platform 21 to the construction height position by tightening the hand chain hoist to carry out the horizontal weld construction of the main board. When pulling, the two sliding U-shaped modules 19 should be stressed. After the weld construction within a certain distance is completed, after moving the sliding U-shaped modules 19, tighten and loosen the hand chain hoist to change the stressed sliding U-shaped modules 19 to achieve the purpose of the operator moving the construction operation platform horizontally. Before moving the sliding U-shaped modules 19, the first adjusting bolt 7 needs to be loosened to reduce the clamping force of the first spring 6. Since the first spring 6 has a certain tension and relaxation force, the steel pulley 3 can pass over some thick and thin plate protrusions on the steel plate surface when moving.

[0044] Step 5: Install the T-clamps 20 onto the facade profile to be installed. Use a hand-operated hoist to pull the profile to the desired installation position for installation. After the transverse welds of the main plate are completed, T-clamps 20 can be used to install the profile based on the above construction plan. Generally, two T-clamps 20 can be used to fix one profile. Fit one T-clamp 20 onto each end of the profile to be installed, and tighten the fastening tapered bolts 12 and the second adjusting bolts 24 to clamp the profile with the T-clamps 20. Then, connect the profile to be installed to the anchor hook of the sliding U-shaped module using the T-clamps 20, wire rope, shackles, and hand-operated hoist. Tighten the hand-operated hoist to pull the profile to be installed to the frame installation line position of the main plate for assembly and positioning. At the same time, personnel can perform assembly and welding of the plates and profiles on the construction operation platform 21.

[0045] The above is merely one implementation of this invention. Other similar methods and structural substitutions can be made based on the same idea, and are not limited to the steps and structural components already described. In summary, the scope of protection of this invention also includes other variations and substitutions that are obvious to those skilled in the art.
