coal trestle

Abstract

The invention discloses a coal transporting trestle and belongs to the technical field of steel structures and concrete. The coal transporting trestle comprises a truss and a plurality of brackets supported under the truss; the truss comprises a sub truss; outriggers are arranged at the two ends of the sub truss; each bracket comprises a first beam, a second beam and two bracket columns; the firstbeam and the second beam are arranged at the top and at the bottom and are fixedly connected with the two bracket columns; and the two adjacent outriggers of the two sub trusses are correspondingly fixed at the top ends of the two bracket columns in the same bracket. By directly placing the outriggers at the top ends of the bracket columns, loads bore on the outriggers are directly transmitted tothe bracket columns without being transmitted by the first beams. At the moment, the bracket columns only bear pressure stress, and connecting nodes between the bracket columns and the first beams donot bear bending moment. Therefore, the mechanical strength requirements of the bracket columns are reduced to reduce usages of reinforcements and concrete are reduced; and therefore, lower engineering cost is realized.

Description

technical field [0001] The invention relates to the technical field of reinforced concrete structures, in particular to a coal transport trestle. Background technique [0002] The coal conveying trestle is an important part of the thermal power plant. Through the coal conveying belt conveyor loaded in the coal conveying trestle, the coal in the coal storage yard is transported to the boiler for combustion to realize thermal power generation. [0003] The coal delivery trestle provided in the related art is as figure 1 As shown, a truss 1 and a bracket 2 are included, and the bracket 2 is supported under the truss 1 . Wherein, the truss 1 includes a plurality of independently arranged sub-trusses A, and legs 11 are provided at both ends of each sub-truss A. The support 2 includes a first beam 21 and a second beam 22 arranged up and down, and two support columns 23 , and the first beam 21 and the second beam 22 are connected to the two support columns 23 at the same time.

Problems solved by technology

Due to the large load on the leg 11, the first beam 21 is compressed and causes a bending moment at the joint between the first beam 21 and the support column 23, thereby affecting the force on the support column 23

At this time, in order to ensure that the first beam 21 and the support column 23 meet the mechanical strength requirements, it is necessary to increase the cross-sectional area and the amount of steel bars of the first beam 21 and the support column 23, which increases the construction cost.
