Special-shaped H-shaped steel beam suitable for pitched roof ridge and connecting joint and construction method of special-shaped H-shaped steel beam

Abstract

The invention discloses a special-shaped H-shaped steel beam suitable for a slope roof ridge, the special-shaped H-shaped steel beam is made of cold-formed thin-walled special-shaped H-shaped steel, and the upper flange and the lower flange of the special-shaped H-shaped steel are provided with dip angles matched with the slope angle of a slope roof. The invention further discloses a fabricated connection joint based on the special-shaped H-shaped steel beam and a construction method of the fabricated connection joint. The special-shaped H-shaped steel beam flange is connected with the H-shaped steel secondary beam flange in a coplanar mode by arranging the inclination angle identical to the slope angle of the slope roof, the connecting joint is simple and reliable, and the roof panel can be laid flatly; the special-shaped H-shaped steel beam is made of cold-formed thin-walled special-shaped H-shaped steel, is light in weight and convenient to transport, assemble, carry and install, and does not need to use large machines; the components are produced and processed by factory standardization, and the precision is high; the self-tapping screws are adopted for connection in field installation, connection holes do not need to be centered, installation is easy and convenient, efficiency is high, environment friendliness is achieved, and the use requirements of assembly type steel structure buildings in villages and towns can be met.

Description

technical field [0001] The invention relates to the field of prefabricated steel structure buildings, in particular to a special-shaped H-shaped steel beam suitable for a ridge of a sloping roof, a connection node and a construction method thereof. Background technique [0002] As an easy-to-construct prefabricated building form, steel frame structure has clear force transmission, good force performance, and has a high potential for assembly, which is suitable for residential building applications in villages and towns. The structural beam as the main force-bearing member needs to meet the inherent requirements of village and town residential buildings for simple construction and fast installation. [0003] The sloping roof has good drainage effect and beautiful appearance, and is widely used in villages and towns. However, the existing ridge beams mostly use ordinary H-beam, and the angle of the sloping roof will cause the ridge beam and the top H-shaped steel roof beam-sec...

Problems solved by technology

[0003] The sloping roof has good drainage effect and beautiful appearance, and is widely used in villages and towns. However, the existing roof beams mostly use ordinary H-shaped steel. The angle of the sloping roof will lead to complex connection nodes between the ridge beam and the H-shaped steel roof beam-secondary beam on the top. , is not conducive to the laying of roof panels, the laying of roof panels is difficult to level, and the connection form is mostly welding, the construction process is cumbersome, and does not meet the requirements of green environmental protection. At the same time, considering the problems of transportation and construction conditions in villages and towns, it is urgent to propose a solution suitable for villages and towns. The form of H-shaped steel beams and its simple assembled joints on the sloping roof of residential buildings
