Problems solved by technology

This has caused huge waste. After each construction is completed, a complete temporary I-beam track is cut into several sections of waste, which is a serious waste. Moreover, the workers perform gas cutting operations on the hanging basket, which is harsh and unsafe, and even There are safety hazards such as fire and falling

Abstract

The invention discloses an auxiliary device for installing a primary truss during construction of a large-span truss type steel structure roof, and an installation method. The device comprises four groups of mechanical arms used for drawing base plates (14); each group of mechanism arm comprises a fixed plate (15), a vertical cylinder (16), a rotary cylinder (17) and a transverse cylinder (18); each fixed plate (15) is connected to one support leg (12.1) of the primary truss (12) in a detachable way, a cylinder body of each vertical cylinder (16) is fixed on the corresponding fixed plate (15), piston rods of the vertical cylinders (16) are fixed with fixed parts of the rotary cylinders (17), rotating parts of the rotary cylinders (17) are fixed with cylinder bodies of the transverse cylinders (18), and fixtures used for clamping the base plates (14) are fixed on piston rods of the transverse cylinders (18). The installation method is characterized by utilizing the mechanism arms to automatically draw the base plates (14). After the auxiliary device and the installation method are used, the base plates (14) can be automatically drawn.

Description

technical field [0001] The invention relates to the construction technology of a large-span truss-type steel structure roof in the field of civil engineering, specifically an auxiliary device for installing a main truss when constructing a large-span truss-type steel structure roof and using the auxiliary device to install the main truss Methods. Background technique [0002] A large-span (generally more than 30m span) truss-type steel structure roof is often used on the top of large-scale venues such as gymnasiums. When constructing this roof, a critical step is the installation and fixation of the large-span main truss. The above installation process will utilize the pre-buried and fixed steel corbels on the inner surfaces of the two concrete side walls of the venue. The specific process is to first fix a temporary I-steel track on the steel corbels of the two side walls , and then put two trolleys on each track, and there are four outriggers on the four corners of the ma...
