[0002] In recent years, with the continuous progress and development of the construction industry, the number of special-shaped structures in high-rise buildings has increased significantly. More and more high-rise building projects have floors with different edge lengths. During the construction process, materials need to be transported by construction elevators. Floors with different edge lengths will cause the gap between the floor edge and the construction elevator to be different in length. This phenomenon will seriously affect the construction progress and reduce work efficiency.

[0003] In the prior art, a reversible connecting plate is usually added to the construction elevator to increase the horizontal length of the construction elevator, thereby reducing or eliminating the gap between the floor edge and the construction elevator to achieve the purpose of material transportation. However, this solution is not suitable for situations where the length difference of the floor edges is large.

Although the device can increase the horizontal length of the floor, the curved plate in the device needs to be fixed to the external frame, and it is not suitable for the connection between the floor and the construction elevator. Summary of the invention

[0005] In order to overcome the problem in the prior art that the length of the floor edge is different from the vacant distance of the construction elevator, which affects the construction progress and reduces the construction efficiency, the utility model proposes a connection device for the construction elevator and the floor, and its detailed technical solution is as follows:

[0007] Furthermore, the steel plate is a 5 mm thick galvanized steel plate with a flat surface.

[0008] Furthermore, the steel bracket includes a horizontal angle steel, a vertical angle steel and an inclined angle steel connected by welding; the vertical angle steel is fixedly connected to the facade via a first connecting piece; the horizontal angle steel is fixedly connected to the steel plate via a second connecting piece; and the two ends of the inclined angle steel are respectively connected to the horizontal angle steel and the vertical angle steel.

[0009] Furthermore, a plurality of parallel steel brackets are connected to the lower surface of the steel plate.

[0010] Furthermore, the first connecting member is an M10X120mm expansion anchor and a 3mm thick galvanized steel gasket.

[0011] Furthermore, the second connecting member is an M12×50 expanded hole bolt and a 3 mm thick galvanized steel gasket.

[0012] The beneficial effects of the utility model are as follows: the connecting device of the utility model is composed of common components on the construction site, and the connection is convenient and easy to manufacture; the utility model increases the length of the floor edge without changing the main structure by arranging a steel plate flush with the horizontal surface of the floor on the facade of the building, so that the length of the floor edge can be unified, which is convenient for the installation of the construction elevator and effectively improves the construction efficiency and construction safety.

[0026] The utility model adopts a construction method in which the connecting device for construction elevators and floors is manufactured in units and installed in sections on site. First, the drilling position is determined according to the civil engineering elevation reference line, and the elevation and left and right positions are checked for deviations. After the reference point is determined, the line is marked; then the anchor position is drilled with an impact drill or a water drill. After the drilling is completed, a special air cylinder, a brush or a compressed air machine is used to clean the dust in the drill hole. It is recommended to repeat this process at least 3 times to ensure that there is no dust and clear water in the hole. The connecting devices are installed one by one in strict accordance with the positioning position. First, the vertical angle steel and the building facade are fixed with anchor bolts, and then the horizontal angle steel and steel plate are fixed with expansion bolts.
