Description
Technical Field
The invention belongs to the technical field of steel structure design and construction, and particularly relates to a steel support structure for supporting a multi-layer overhead gallery.
Background
Taking belt conveying as an example, factories which take bulk materials as raw materials for production or finished products generally have a large number of conveying devices, most of which adopt belt conveyors, and a plurality of conveyors higher than the ground are supported on a steel structure conveying corridor structure. The gallery structure includes a plurality of steel support structures, and a plurality of large-span steel truss structures supported on the steel support structures.
The main function of the steel support structure of the belt conveyor gallery is to provide support restraint for the horizontal truss structure of the gallery, and at the same time, to bear the horizontal loads and effects acting on the gallery structure, such as: wind load, earthquake load and the like as the vertical bearing structure and the anti-side structure of the whole gallery structure. Therefore, the supporting structure needs to have enough lateral rigidity besides enough vertical and horizontal bearing capacity, and the lateral displacement of the conveying gallery is controlled to meet the specification requirement.
The structural construction of the steel bracket generally adopts two forms of a plane lattice type construction of 2 columns and a space lattice type construction of 4 columns. The choice of the structural form of the support depends on safety and economy, in particular, the choice of the structural form of the support and the height of the support, as well as the connection mode related to the truss structure, generally the height of the support exceeds 20m, or the conveying corridor on the support exceeds 1 floor, or is positioned at the horizontal expansion joint of the conveying corridor structure, and 4-column supports are preferably selected. The height is less than 20m, and when the support structure is used as a support structure of a single-layer conveying truss, a 2-column support is preferably selected.
The common support structure is composed of upright columns, horizontal rods, inclined rods, column tops and column feet, the horizontal rods and the inclined rods are generally steel tubes or double-angle steel sections, the upright columns are steel tubes or H-shaped steel, and 2 the upright columns of the upright support are mostly H-shaped steel. The horizontal rod and the inclined rod are hinged with the upright post, and the column foot and the column top of the upright post are respectively hinged with the foundation and the truss support.
The horizontal rods and the inclined rods of the support structure are generally continuously and uniformly arranged along the full height of the upright column to form a geometric invariant system, under the action of load, the internal force of each rod piece of the support is mainly axial force, and meanwhile, the bending moment and the shearing force are small, and the bending moment and the shearing force of the rod piece can be generally ignored in the design calculation. Through calculation, each rod piece of the support selects a reasonable section to limit the slenderness ratio of the rod piece, and can provide enough bearing capacity and lateral rigidity for the support structure.
When the support structure supports 2 or more conveying galleries, belt equipment of the gallery at the lower layer passes through the support body, inclined rods of the support can collide with the belt equipment and are removed, so that the inclined rods of the support cannot be continuously arranged along the height of the support, the bearing capacity and the rigidity of the structure are weakened, and certain measures (a new structural form needs to be adopted) need to be taken to improve the structural arrangement of the support so as to ensure that the support structure has enough bearing capacity and lateral rigidity and is used as a support structure of the truss structure.
The traditional solution is as follows: change the connected node type of horizon bar and stand, be about to the horizon bar and the support stand connected mode of two upper and lower horizontal planes that the belt passes through the position change rigid connection into, make the bearing structure who has removed the down tube keep geometry unchangeable, satisfy the bearing capacity through increaseing the member section simultaneously, nevertheless have following problem:
1. the change of the bracket node type changes the internal force type of the rod piece, and the material usage amount is increased. After the diagonal rods are removed, the internal force of the vertical columns in a certain range from top to bottom, except for the axial force, also has larger bending moment and shearing force, meanwhile, the horizontal rods which are rigidly connected with the vertical columns are also the same as the vertical columns of the support, the internal force comprises the axial force and the larger bending moment and shearing force, the cross sections of the rod pieces need to be increased to meet the requirement of bearing capacity, and finally, the material usage amount of the structure is increased.
2. The arrangement of the anti-side components of the bracket is discontinuous and uneven, the lateral rigidity of the part where the diagonal rods are removed is suddenly changed, and the lateral displacement of the bracket is increased. According to the principle of virtual displacement, under the unit internal force, the axial force generates displacement which is less than 1% of that generated by bending moment, but the increase of the cross section of the bearing capacity calculation member and the increase of the displacement calculation are not in the same order of magnitude, so that under the condition of meeting the bearing capacity, the displacement of the structure is increased greatly, the rigidity of the structure is changed suddenly, and the integral stress of the structure is not favorable.
3. The cross section of the member is not optimized, the member is an open-type double-angle steel cross section, the types of parts are multiple, the processing and manufacturing engineering quantity is large, an anti-corrosion dead angle is easy to form, and the structure is not beneficial to corrosion prevention during use.
