A construction method for the construction structure of a heating furnace roof hanging beam

Abstract

The invention discloses a construction method for a construction structure of a suspended beam at the top of a heating furnace. The construction structure comprises a plurality of parallel and level I-steel (2) distributed on the same plane at intervals, wherein connecting steel bars (3) are arranged at the end parts of the I-steel (2) and connected with the I-steel (2) in a fastened manner. The invention further discloses the construction method for the construction structure of the suspended beam at the top of the heating furnace. According to the technical scheme, the problems in the prior art are effectively solved, the cutting operation is complete when welding points are removed, the inspection operation is easy, efficient and simple, free expansion of the I-steel is effectively guaranteed, and the requirement on the quality of workers is lowered; the construction structure is firm to fix, convenient to clean and high in framework supporting speed, shortens the work period and improves the construction quality.

Description

technical field [0001] The invention belongs to the technical field of production equipment in the metallurgical industry, and relates to the construction technology of a large-scale heating furnace. More specifically, the invention relates to a construction method for a construction structure of a hanging beam on the top of a heating furnace. Background technique [0002] Hanging beams on the roof of large-scale heating furnaces are key tasks in the construction of heating furnaces. The quality of furnace roof construction has a profound impact on the use of heating. [0003] At present, domestic heating furnace construction units have long used the pre-fixed technology of spot welding at both ends of small I-beams. After the furnace roof is poured, in order to ensure the free expansion of the I-beam, the solder joints of the I-beam are removed again. [0004] The construction method in the above-mentioned prior art is as figure 1 As shown, the welding spot 1 is located a...

Problems solved by technology

[0005] This construction method is difficult to master and requires high technology and sense of responsibility for the construction personnel. Especially when removing the solder joints after construction, gas cutting or hand grinding wheel grinding technology must be used, which makes it difficult to cut through and difficult to remove. Inspection, even the workers use prying method for inspection, causing the furnace roof brick to break, causing serious accidents and extremely bad effects. Some construction uses gas cutting and blowing to cause damage to the contact surface of the hanging beam and the furnace roof girder, which affects the life of the furnace roof
