Problems solved by technology

As an important part of prefabricated construction, hoisting runs through all construction links of prefabricated building structures. In actual engineering, when prefabricated concrete components are hoisted, especially during the hoisting of prefabricated walls, the inclination and excessive deformation of the external hanging panels lead to cracking, Suspension nails are pulled out, semi-grouting sleeves and pre-embedded steel bars are difficult to connect accurately, especially based on the fact that the current prefabricated construction technology mainly relies on construction workers with low education and lack of prefabricated construction experience, resulting in prefabricated construction. The construction quality of the building is lower than that of the cast-in-place structure, which hinders the development of building industrialization
[0003] In actual engineering, the hoisting of prefabricated wall panels mainly relies on the cooperation of the tower crane driver and the ground personnel. However, the tower crane driver is far away from the prefabricated wall panels during the hoisting process, and mainly relies on the command of the ground personnel for remote operation, and mainly relies on wire rope hoisting , during the hoisting process, the prefabricated wall shakes a lot, and only rely on the manpower control of the floor technicians to reduce the shake of the prefabricated wall, and only rely on the floor technicians to use the mirror to reflect the naked eye to observe the semi-grouting sleeve and pre-embedded steel bars According to the alignment situation, the precise connection between the half-grouting sleeve and the pre-embedded steel bar is implemented, resulting in the collision between the inner wall of the half-grouting sleeve and the pre-embedded steel bar, which does not meet the requirements of the specification, and even the pre-embedded steel bar cannot be installed into the half-grouted sleeve The situation is often encountered, resulting in low construction quality and efficiency

Embodiment 1

[0050] The prefabricated wall panel hoisting method includes the following steps:

[0051] The first step is to connect the lifting ring 1102 of the prefabricated wall panel hoisting tool to the tower crane;

[0052] The second step is to determine the hoisting fixing hole 100 of the prefabricated wall panel 1 to be hoisted;

[0053] According to the hoisting connection position on the hoisting connection section steel 1101 of the prefabricated wall panel hoisting tool, the corresponding hoisting fixing holes 100 are reserved during the production process of the prefabricated wall panel 1 to be hoisted;

[0054] In the third step, the prefabricated wall panels 1 to be hoisted are laid out for construction;

[0055] According to the construction drawing, carry out the construction line-out of the corresponding position of each prefabricated wall panel 1;

[0056] The fourth step is to install auxiliary installation tools for prefabricated wall panels;

[0057] The plane outl...

Embodiment 2

[0061] The prefabricated wall panel hoisting method of Embodiment 1 can also be more specific, including the following steps:

[0062] The first step is to make and install prefabricated wall panel hoisting tools,

[0063] The prefabricated wall panel hoisting tool includes two sets of hoisting connecting sections 1101 and three-level sliding components from bottom to top; the four-piece in-line hoisting connecting section steel 1101 includes eight circular hoisting connecting holes 1109, of which the four hoisting connecting holes 1109 are one Each group of hoisting connection holes 1109 is distributed in a square into two rows, a total of four rows; a group of two circular sliding block connection holes are set on the top of the hoisting connection section steel 1101, and every two pieces of hoisting connection section steel 1101 as a group is fixedly connected to the first sliding block 1103-1 and the second sliding block 1103-2 through connecting bolts 1108, and the top of...

Embodiment 3

[0096] The hoisting method of the prefabricated wall panel in Embodiment 1 or Embodiment 2 may be more specific. In the fifth step, when hoisting and installing the prefabricated wall panel 1, the following steps may also be included:

[0097] Connect the two hoisting ropes 1110 on the prefabricated wall panel hoisting tool to the tower crane hook;

[0098] The ground technician instructs the tower crane driver to operate the tower crane to move the prefabricated wall panel hoisting tool to the top of the prefabricated wall panel 1 to be hoisted. 1 position alignment;

[0099] The ground technician uses the controller to control the first rotating motor 1107-1 to drive the first sliding block 1103-1 and the second sliding block 1103-2 to move to the position where the hoisting fixing holes 100 at both ends in the length direction of the prefabricated wall panel 1 to be hoisted are connected. The position of the vertical line;

[0100] The ground technician uses the controlle...
