High-heat-insulation fire-proof steel section splicing and spot welding structure

Abstract

The invention provides a high-heat-insulation fire-proof steel section splicing and spot welding structure. The middles of bending troughs in the two ends are of square convex structures, and the square convex structures and the backs of the bending troughs form plane materiel connection fastening troughs. Connection inserting pieces are adopted for a plane material connection device, one ends ofthe connection inserting pieces and a required plane material form an integrally-formed structure, the other ends of the connection inserting pieces are inserted into the plane materiel connection fastening troughs, and the ends, inserted into the fastening troughs, of the connection inserting pieces are provided with bending protrusions. The high-heat-insulation fire-proof steel section splicingand spot welding structure provided by the invention is simple in structure and high in practicability, through splicing of the plane material and connection device, manufacture factories only need tostore a great amount of connection device structures, once different plane materials of different models are required, a heat-insulation section structure can be formed through timely splicing combination, and material storage is greatly saved; and through structural design of spot welding and a strip-shaped heat-insulation cavity, the heat conduction speed is greatly lowered, and the heat-insulation effect is better.

Description

technical field [0001] The invention belongs to the field of spliced ​​profiles, and in particular relates to a plug-in spot welding structure of high heat-insulation and fire-proof steel profiles. Background technique [0002] In the prior art, general fireproof profiles are integrally formed according to the required surface material requirements. According to different surface material requirements, manufacturers generally need various types of profile production materials, which not only consumes a lot of raw materials seriously, Moreover, it affects the normal operation and turnover of manufacturers; moreover, the fire-resistant steel profiles on the market are designed in one piece, which is not outstanding in heat resistance. Therefore, the development of a fire-resistant steel profile that slows down the heat conduction speed has become The most important issues facing manufacturers. Contents of the invention [0003] In order to solve the above-mentioned technica...
