Pipe truss processing bed-jig and pipe truss manufacturing process

Abstract

The invention discloses a pipe truss processing bed-jig and a pipe truss manufacturing process, and solves the problems that the pipe truss processing efficiency is low and the accuracy is hard to effectively control in the prior art. The invention provides the technical points that the pipe truss processing bed-jig comprises two groups of chord member placement shelves for placing chord members,wherein each group of chord member placement shelf comprises multiple groups of vertically arranged installation rods; connecting rods are connected between the bottom ends of the multiple groups of installation rods of each chord member placement shelf; the arrangement directions of the installation rods in the two groups of chord member placement shelves are in parallel; the installation rods inthe two groups of chord member placement shelves are in one-to-one correspondence; connecting wires of the installation rods are perpendicular to the extending directions of the chord member placement shelves; two groups of chord member placement plates are movably arranged on the installation rods; positioning pieces are arranged between the chord member placement plates and the installation rods; and fixed pieces for fixing chord members are arranged on the chord member placement plates. Through the scheme, the chord members in a pipe truss are fixed in advance by utilizing the processing bed-jig, so that the pipe truss is further conveniently processed as a whole, the efficiency is improved, and a final finished product is more accurate.

Description

technical field [0001] The invention relates to the technical field of pipe truss manufacturing, in particular to a pipe truss processing tire frame and a manufacturing process of the pipe truss. Background technique [0002] Pipe trusses include multiple groups of parallel chords and floating rods obliquely connected between two chords. The common forms are triangular pipe trusses composed of three groups of chords and square pipe trusses composed of four groups of chords. The trusses make the truss structure economical in materials and light in weight. It is easy to form various shapes to suit different purposes. For example, it can be made into simply supported trusses, arches, frames and towers, etc., which are commonly used in railway stations and subway stations. [0003] When the existing pipe truss is manufactured and processed, the chords and floating rods will be manufactured first, and then the floating rods will be welded and installed on one side of each chord i...

AI Technical Summary

Problems solved by technology

However, in the above processing process, since the installation of each group of chords and the floating rods on them is carried out independently, although the installation and construction of the overall pipe truss can be divided into several parts and carried out at the same time, the labor cost is relatively large, and the floating When the rods are individually welded on one chord, it is inevitable that there will be deviations, which will make it impossible to connect the deviated floating rods to another chord when the two chords are finally connected, which will easily lead to work delays and rework. It also makes it impossible to increase the efficiency to a higher level
