Description
Technical Field
The invention relates to a horizontal supporting device for a power station boiler, and belongs to the technical field of boiler supporting devices.
Background
In recent years, the power industry is continuously and rapidly developed, and the steel structure of the power station boiler is continuously optimized, so that the refinement is realized, and the better is realized. The horizontal support is used as an important component of the steel structure, and if reasonable consideration is not given in design, the difficulty is increased for subsequent production, transportation and installation. The horizontal support arrangement is generally designed to be matched with a heating surface pipeline, and in the steel structure design, horizontal supports are matched with beams, horizontal supports are matched with columns, horizontal supports are matched with suspenders, and the horizontal supports are matched with pipelines. The horizontal supports in the steel structure are arranged from the first layer to the top layer, the number is large when the horizontal supports are accumulated, and the importance of the horizontal supports can be seen. When the horizontal support is installed, the deviation must be strictly controlled in the installation process so as to avoid generating excessive accumulated deviation from the installation of the beam and causing unnecessary errors.
When the horizontal support construction drawing is designed, the horizontal support cross section is welded by buckling two channel steels, and the channel steels are buckled by clamping a partition plate in the middle and are welded and connected. The length of the welding between the horizontal support section and the connecting plate is determined according to the axial force, and the length of the opening and the number of the bolts are determined. The opening width generally is 14mm, and the connecting plate width adds 40mm for square tube width, and the connecting plate overlap joint adopts bolted connection on the horizontal support gusset plate. The horizontal support gusset plate is connected with the connecting beam through the angle steel by bolts, and the angle steel and the horizontal support gusset plate are formed by welding three surfaces. The connecting angle steel is divided into single-sided angle steel and double-sided angle steel and is mainly determined according to the height of a connecting beam, the single-sided angle steel is adopted when the beam height is less than 350mm, and the double-sided angle steel is adopted when the beam height is more than 350 mm. The existing problem is that the construction drawing is designed, and two channel steels need to be welded by using a partition plate during production. The splicing process is added, the welding workload is large, the cost is increased, and the positions where the two channel steel buckles without the partition plates need to be sealed by the sealing strips with the thickness of 6mm and the width of 50mm, and meanwhile, the processing procedure and the workload are increased. The total weight of the steel structure increases. And a great deal of workload is added to the design, production and installation of the construction drawing. The construction progress of the power plant is not facilitated to be smoothly and orderly carried out (see the figure 1-figure 3).
