The present utility model will be further described below through specific application examples of the present utility model,

In the practical application of the utility model, the structure of the building is an assembled integral frame shear wall structure, with 18 floors of the tower above ground, one floor of the podium, and two floors of the underground, with an assembly rate of about 60%. Prefabricated laminated beams, prefabricated stairs, and prefabricated cladding panels, of which there are 38 prefabricated cladding panels per floor, with an average weight of about 3 tons. In this embodiment, the construction of the prefabricated external hanging board adopts the concrete external hanging board hoisting construction structure of the present invention.

As shown in Figure 2, in the first 1d of the formal hoisting, use the measuring instrument to release the PC board access control line and the left and right control lines on the floor 2, as the basis for the adjustment of the plane position, and release the 1000mm elevation line on the floor 2 prefabricated column as the The basis for height adjustment. On the 1000mm elevation line of the floor that is not lifted, the 1000mm elevation line of the floor is popped up, which is used to control the elevation of the outer panel in cooperation with the prefabricated column 1000mm elevation line during the installation process.

Temporary lifting points 3 are welded on the PC embedded parts installed on floor 2, and the external hanging boards 1 on the upper and lower floors are installed on the temporary lifting points 3 on each floor. Before the official hoisting, a trial hoisting should be carried out. First, the outer hanging plate 1 is hoisted off the ground by 500mm, and then the hoisting is stopped to check the braking performance of the tower crane, whether the slings and rigging are reliable, so that the components are level and the hooks are stressed. After the uniform and correct, the formal lifting process can be carried out.

The external hanging board 1 is lifted smoothly by the spreader, and then the boom is rotated at a constant speed. After approaching the building, the hoisting worker catches the auxiliary rope with a hook, and pulls the external hanging board 1 to 50cm above the installation position. Make it descend slowly, use the 3T chain hoist 42 to convert the hanging point of the external hanging board 1, and remove the hanging point of the tower crane.

When slowly descending, use the side line and end line of the wall panel released from the floor to make the outer wall panel in place initially. Use the temporary fixing bolts 6' of the upper wall panel and the leveling bolts 4' of the bottom to perform preliminary positioning, and only need to make fine adjustments later. After the initial position, carry out the installation of the inclined support of the external hanging board 1, that is, the installation of the inclined rod. The specific operation is to hang the inclined support on the installed steel plate ring on the external hanging board 1, and hit the middle point of the cross line of the expansion bolt that has been bounced on the floor. Drill the expansion bolt hole, put another steel plate ring, drive the expansion bolt, connect the diagonal support, and complete the reinforcement connection of the upper temporary fixing bolt 6' before the tower crane loosens the hook.

After the external hanging board 1 is hoisted into place, as shown in Figure 1, according to the pre-placed floor control line, the temporary fixing bolt 6 in the embedded part 5' of the second floor structure, that is, the MJ6/MJ1b/MJ1c embedded part 'That is, the horizontal position of the M20 type positioning bolt, first determine the position of the wall in the outdoor direction. After that, adjust the leveling bolt 4' of the M24 type high-strength bolt, and align the prefabricated column with the level line that pops up on the outer hanging board 1 so that it is at the same height. Set up a level to scan, and then determine the elevation of the external hanging board 1.

Repeatedly check the horizontal position of the outer cladding board 1 to confirm that its positioning is accurate, and finally fix the first floor structure embedded part 7 of the bottom connection point and the steel embedded part 3' at the bottom of the outer cladding board through gaskets and nuts. Embed the connection between MJ6a/MJ6b/MJ6c and MJ2, so as to finally fix the position of the plug-in board.

After the bottom port of the external hanging board 1 is basically adjusted, use the inclined support for fine adjustment, and the allowable error of verticality is 2mm. Drag the line board, supplemented by a level ruler to measure the distance between the upper and lower ports and the line hammer, or use a ruler to check the verticality of the external hanging board. If it is found that the verticality error exceeds the allowable range, the diagonal bracing must be fine-tuned. All the pop-up control lines should be compounded. If the verticality error is too large due to the manufacturing error of the external panel itself, you can adjust the position of the lower port according to the elastic lines on the panel to ensure the verticality of the external panel.

After the external hanging board 1 is in place, immediately carry out the welding and fixing of all the embedded parts. The welding adopts single-sided welding. After the welding is completed, the 3T chain hoist 42 is released from the hook and the diagonal support is removed.

The hoisting structure adopted in the specific embodiment of the present invention includes an upper suspending rope 41, a hand chain hoist 42, a shackle 43, a lower suspending rope 44, and a suspending buckle 45. When the operator operates on the floor structure 2, the side of the floor 2 It is necessary to set up protection 5 on the upper part, and the operator will carry out operation and construction on the mobile operation frame.

The relevant content of the present invention has been described above. Those of ordinary skill in the art will be able to implement the present invention based on these descriptions. Based on the above-mentioned contents of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
