A method of installation and construction of long-span pipe truss engineering

Abstract

The invention relates to a method for installation and construction of a large-span pipe truss project, which includes a fixed base, a lifting platform, a fixed plate, a driving motor, a supporting mechanism and a driving mechanism, a lifting platform is installed on the top of the fixed base, and the top of the lifting platform is fixed and installed by bolts There is a fixed plate, the top of the fixed plate is provided with a motor placement slot, the drive motor is installed inside the motor placement slot, the outer wall of one end of the output shaft of the drive motor is welded with a driving pulley, and a support mechanism is arranged above the fixed plate, and the support mechanism is connected with the fixed plate. A driving mechanism is provided in the gap, and the driving force of the driving mechanism is a driving motor. The present invention can be effectively applied to the support work of trusses with different radians. While supporting in the vertical direction, the position in the horizontal direction is locked at the same time, thereby effectively ensuring the safety of fixing the truss in the present invention.

Description

technical field [0001] The invention relates to the technical field of truss installation and construction methods, in particular to a large-span pipe truss engineering installation and construction method. Background technique [0002] Truss A structure consisting of members connected to each other by hinges at both ends. The truss is composed of straight rods and generally has a plane or space structure of triangular units. The truss members mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save materials compared with solid web beams, reduce self-weight and Increase stiffness. The advantage of the truss is that the rods mainly bear tension or pressure, which can give full play to the role of materials, save materials, and reduce structural weight. Commonly used steel trusses, reinforced concrete trusses, prestressed concrete trusses and wooden trusses. [0003] However, the installation and...

Problems solved by technology

[0003] However, the installation and construction methods of large-span pipe truss projects in the market currently have the following problems in the operation process: a. Since the traditional large-span pipe trusses all adopt arc-shaped structures, during the installation and construction process, it is necessary to place support devices at the bottom of the truss , to increase the bearing capacity of the truss, but the traditional support device has certain limitations, that is, the same support device cannot be applied to the support work of trusses with different radians, resulting in low practicability; b. Due to the traditional long-span tube Truss engineering installation and construction method When supporting the truss, the support device can only support the vertical direction of the truss, but cannot lock the horizontal direction of the truss, resulting in low overall safety of the device
