GRC composite wallboard lifting appliance and lifting construction method

Abstract

The invention relates to a GRC composite wallboard lifting appliance and a lifting construction method. The appliance comprises a horizontal base board, a front vertical plate and a rear vertical plate are welded to the front end and the rear end of the horizontal base plate respectively, a lifting lug are welded to the middle of the horizontal base plate, an interval for accommodating an end partof a GRC composite wallboard is surrounded by the front vertical plate, the rear vertical plate and the bottom surface of the horizontal base plate, the length of the front vertical plate is larger than the distance from a pre-embedded fixing bolt at the upper portion of the GRC composite wallboard to the upper edge of a wall body, a transverse groove used for accommodating the pre-embedded fixing bolt is formed in the left side or the right side of the front vertical plate, and the distance from the transverse groove to the lower edge of the horizontal base plate is larger than the distancefrom the pre-embedded fixing bolt at the upper portion to the upper edge of the wall body. According to the lifting appliance, the structure is simple, the design is reasonable, the use is convenient,the lifting construction efficiency of a GRC outer wall is improved, a pre-embedded fixing screw of a GRC outer wall composite wallboard is used as a lifting point, so that a special lifting point pre-embedded part does not need to be independently arranged for the outer wallboard, the structure of the outer wallboard is simpler, and the design and manufacturing cost of the outer wallboard is reduced.

Description

technical field [0001] The invention relates to a GRC composite wall board hanger and a hoisting construction method. Background technique [0002] The prefabricated building can reduce the wet work on the construction site. The main body of the project is split into components. The production of the components is mainly completed in the prefabricated factory. After the prefabricated components are transported to the site, the components are assembled on site. This construction method greatly reduces the demand for manpower on the construction site and accelerates the construction speed, but this method puts forward higher requirements on the mechanical hoisting equipment and hoisting technology on site. [0003] In the prior art, there is no technical description on how to hoist, fix and connect GRC exterior wall composite wall panels during construction. The construction unit carries out the hoisting construction according to the specific form and connection method of the...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, in the hoisting construction of GRC exterior wall composite wall panels, it is not easy to lift and install the exterior wall panels without special lifting points during the hoisting process. For GRC exterior wall composite panels with special lifting points Wall panels are not only expensive, but may also lead to low installation efficiency
