A prefabricated building truss structure

Abstract

The invention relates to the technical field of construction engineering equipment, and discloses an assembled building truss structure, which includes a truss connecting rod, a fixing sleeve is arranged on the outer surface of the truss connecting rod, and fixed sleeves are fixedly installed on the upper and lower sides of the outer surface of the fixing sleeve. The fixed clamping plate, the middle part of the outer surface of the fixing sleeve and between the two sets of fixed clamping plates is provided with a mounting plate, the outer surface of the adjusting screw is fixed with a movable pressure sleeve through a nut, and the inner movable sleeve of the movable pressure sleeve is connected with a movable The tongue is pressed, and one end of the movable tongue is in contact with one end of the fixed sleeve. The prefabricated building truss structure, for the setting of auxiliary brackets, can conveniently and flexibly install auxiliary straight rods between the entire building truss structure to form a stable and effective triangular structural unit in it, increasing the stability of the prefabricated building truss structure and the stiffness of the entire truss structure, thereby effectively improving the safety and stability of the prefabricated building truss.

Description

technical field [0001] The invention relates to the technical field of construction engineering equipment, in particular to an assembled building truss structure. Background technique [0002] A building truss is a planar or spatial structure composed of straight rods and generally has a triangular unit structure. Increase the rigidity of its structure, and then act as a stable support structure for the roof of the building factory. [0003] At present, the existing building trusses are made by welding, and are installed on the supporting frame by means of fixed supports at both ends. However, the building trusses are generally large in size. If they are welded on the ground, the Assembly is difficult and requires high precision. It cannot be adjusted after the welding is completed. Once the deviation is large, the entire building truss cannot be assembled normally. It needs to be cut and re-welded, which is time-consuming It is laborious and the work efficiency is low. If...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a prefabricated building truss structure, which is simple to assemble, can be fine-tuned according to the actual installation situation, has high installation accuracy and stability, is easy to disassemble, and can effectively reduce the truss for some non-permanent construction projects. The advantage of production cost solves the problem that the existing building trusses are all welded during production, which is difficult and requires high precision, and it cannot be adjusted after the welding is completed. Once the deviation is large It will lead to the failure of normal assembly of the entire building truss, which is time-consuming and laborious, and the work efficiency is low. At the same time, the building truss of the welded structure is a permanent project. The problem of high production cost
