A kind of volcanic rock inorganic mineral fully poured busbar horizontal multi-layer gantry support

Abstract

The invention discloses a horizontal multilayer gantry frame of a volcanic rock inorganic mineral matter fully-poured bus. The horizontal multilayer gantry frame comprises two horizontal multilayer gantry frame assemblies which are welded on a building floor plate or the ground. Each horizontal multilayer gantry frame assembly comprises two suspension rods, one crossbeam, at least one top beam, upper support seats and lower support seats. The two suspension rods are arranged to be parallel and are both vertical to the building floor plate. Two ends of each of the two suspension rods are welded with embedded parts of the building floor plate. The crossbeam and the at least one top beam are connected between the two suspension rods and are vertical to the two suspension rods. The upper support seats and the lower support seats are arranged in pair and are positioned between the crossbeam and the top beam or among multiple top beams. Each upper support seat and each lower support seat are connected and fixed with the adjacent crossbeam or the adjacent top beam respectively, so as to jointly clamp and fix a bus body in a cavity formed by the upper support seat and the lower support seat. With the horizontal multilayer gantry frame provided by the invention, the accuracy and the safety of the installation dimension are improved, the installation space and the installation material are saved at the same time, and the bus route is enabled to be neat and clean.

Description

technical field [0001] The invention relates to the technical field of power supply distribution and transmission, in particular to a horizontal multi-layer gantry support for volcanic rock inorganic mineral all-cast bus bars. Background technique [0002] At present, the horizontal support method of the domestic busbar mainly adopts the bolt hoisting method. The disadvantage of the bolt hoisting method is that it cannot meet the stability and safety in the case of external fluctuations, and is prone to swing and twist; the bolt hoisting method, the busbar body only Supported by the upward force of the angle iron, the busbar is not firmly locked on the bracket. In the case of strong seismic waves, it may jump off the bracket, so that a huge force occurs between the busbar and the bracket, causing The busbar was cracked and damaged; because the characteristics of easy swing and distortion brought inconvenience to the installation during the construction process, the construct...

[0002] At present, the domestic busbar horizontal support method mainly adopts the bolt hoisting method. The disadvantage of the bolt hoisting method is that it cannot meet the stability and safety in the case of external fluctuations, and is prone to swing and twist; the bolt hoisting method, the bus body only Supported by the upward force of the angle iron, the busbar is not firmly locked on the bracket. In the case of strong seismic waves, it may jump off the bracket, so that a huge force occurs between the busbar and the bracket, causing The busbar was cracked and damaged; because the characteristics of easy swing and distortion brought inconvenience to the installation during the construction process, the construction personnel could not accurately determine the position of the screw hanger point, resulting in the phenomenon of left and right heights of the components after installation; the bolt hoisting method must be installed and fixed on site, and cannot be advanced Fix the installation bolts well, which brings great inconvenience to the construction and installation
