Embodiment Construction
[0038] The present invention is described in detail below with reference to accompanying drawing and embodiment:
[0039] attached Figure 1-3 It can be seen that a hoisting method for a three-story composite steel column sandwich thermal insulation exterior wall panel of a prefabricated steel structure residence, the specific construction steps are as follows:
[0040] 1) Hanging point setting
[0041] The hoisting points of the multi-layer prefabricated exterior wall panels are set to 4 points for hoisting, the top of the steel column of the exterior wall panels is set at 2 points, and the middle section of the multi-layer prefabricated exterior wall panels is set with 2 hoisting points;
[0042] The top lifting point is the connecting ear plate of the outer wall panel, and the middle lifting point is the lifting hole opened on the upper flange plate of the steel beam corbel of the multi-layer platform;
[0043] 2) Spreader preparation
[0044] 2 pairs of hoisting slings ...

The invention discloses an assembled-type steel structural residence three-layer composite steel-column filled heat-insulation outer wall plate lifting method. The method includes the steps that two hoisting machines are adopted to lift components; the main hoisting machine sets a lifting point at the top of an outer-wall-plate steel column, the auxiliary hoisting machine sets a lifting point at the middle end of the outer-wall-plate steel column, and the lifting points are fixed firmly; the two hoisting machines synchronously conduct lifting, and the top main lifting speed of the main hoisting machine at the top is greater than that of the middle-end auxiliary hoisting machine; when an outer wall plate is lifted to be five meters away from the ground, middle-end lifting tools are removed; the main hoisting machine starts to lift the outer wall plate, after a perching height is reached, the outer wall plate moves horizontally relative to a perching point, then, a mounting position is reached, and mounting is completed. The assembled-type steel structural residence three-layer composite steel-column filled heat-insulation outer wall plate lifting method improves the construction quality and the mounting accuracy, accelerates the on-site construction, manual operation is reduced, engineering costs are saved, and the situation is prevented that in the process of lifting the outer wall plate, due to steel structural concrete deforms, concrete outer wythes crack.
Description
technical field [0001] The invention relates to a building construction method, in particular to a hoisting method for a three-layer composite steel column sandwich heat-insulating outer wall panel of a prefabricated steel structure residence. Background technique [0002] For the installation of traditional prefabricated exterior wall panels, the exterior wall panels are erected on the exterior wall panel storage racks during installation, and can be lifted and installed directly. This method is only applicable to the case where the height of the prefabricated exterior wall panels is not large. This patent relates to the installation and fixation technology of multi-layer prefabricated exterior wall panels of prefabricated steel structure houses. Prevent the outer pages of multi-layer exterior wall panels from cracking and fix them with multi-layer exterior wall panels. [0003] In the installation and construction of prefabricated residential exterior wall panels, the tra...
