Problems solved by technology
However, the traditional construction technology of using tower cranes to install the laminated slabs cannot meet the accuracy requirements of the installation position, and the installation process requires workers to continuously adjust the horizontal position of the laminated slabs, and the overall work efficiency is low, and it takes a long time Occupying the tower crane to assist the installation of laminated panels cannot meet the requirements of rapid construction

Embodiment Construction
[0037] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0038] see Figure 2 to Figure 8 , a trolley for installing laminated plates, including a movable base 1, an outer stand 2 fixed on the base 1, an inner stand 3 sleeved in the outer stand 2 and movable up and down relative to the outer stand 2, and fixed on the The top support 4 on the inner stand 3 top surface.
[0039] The base 1 includes a base body 11 and moving wheels 12 connected under the base body 11 . As an embodiment of the seat body 11, the seat body 11 can be welded into a cross shape by using I-beams. In this embodiment, the seat body 11 includes a long steel 111 and short steel 112 arranged perpendicular to the long steel 111 and welded on both sides of the middle of the long steel 111, the long steel 111 and the two short steel 112 are connected to form a cross And the top surface and the bottom surface are respectively flush. ...

The invention relates to a construction technique for installing a laminated slab with a tower crane to install a laminated slab, comprising the following steps: walking the trolley to a designated area below the installation position of the laminated slab; adjusting the top brace to rise above the top surface of the beam-column structure, The tower crane lifts the laminated slab and places the laminated slab on the top surface of the top support; the trolley moves to fine-tune the position of the laminated slab; vertical poles are erected under the four corners of the laminated slab; The laminated slab; the top brace continues to descend, the top brace is separated from the laminated slab, and the trolley walks to the installation position of the next laminated slab; repeat steps 1 to 5 until the last laminated slab on the floor; the tower crane lifts the trolley away from the construction site Floor; the last laminated slab is hoisted by the tower crane, and manually assisted to install it to the designated position. This process can greatly reduce the occupancy time of the tower crane, realize the accurate and fast installation of the laminated slab, improve the construction efficiency and reduce safety risks, operating costs and labor intensity of workers.
Description
technical field [0001] The invention relates to the technical field of laminated slab construction technology, in particular to a construction technique for installing a laminated slab with a tower crane by using a trolley for installing the laminated slab. Background technique [0002] Traditional laminated panels are hoisted by tower cranes and require manual installation with manual assistance. Specifically, see figure 1 , the traditional construction process of the laminated slab is as follows: the tower crane lifts the laminated slab to be installed, and erects four vertical poles under the four corners of the laminated slab. position, the tower crane slowly descends, and the artificially assisted tower crane positions the laminated slab, and the four vertical poles below the laminated slab catch the laminated slab. [0003] Due to the low precision of the superimposed slab installed by the tower crane, in order to improve the installation efficiency of the superimpos...
