Description

Technical Field

[0001] The present invention relates to the field of assembled steel structure houses, and in particular to an assembled equal-length vertical web truss slope roof beam system structure. Background Art

[0002] Compared to light steel multi-ribbed structures, framed steel structures are popular for their high bearing capacity, good isolation, and lack of vibration. Furthermore, their sloping roof structures allow for internal voids, effectively utilizing space. However, framed steel structures are more difficult to construct when constructing complex sloping roofs, especially multi-slope roof structures. The steel beams of framed steel structures are generally H-shaped beams, forming the large-span voided roof frame. The purlins on the beams then form the roof's external support structure. When implementing complex multi-slope roof structures, the H-shaped beams often intersect in three dimensions at multiple angles and directions at the nodes. This prevents the flanges and webs of the H-shaped beams from being connected in the same plane, resulting in complex end faces of the node connection components. This makes both the fabrication of the end face cutouts at the beam nodes and the on-site connection of the nodes difficult. To achieve rigid connection requirements, the webs and flanges of each beam must be connected separately. Consequently, fabricating the component ends, on-site welding between components, or fabricating the nodes individually are inconvenient. The thin-walled steel section adopted in the light steel dense-rib structure is connected by self-tapping screws to form a triangular truss called a mountain beam when forming the roof. The triangular trusses of different sizes and angles are used to form the support of the roof through a denser arrangement, so that the light steel dense-rib structure is not sensitive to the complexity of the roof. Its disadvantage is that the space above the lowest point of the slope is occupied by the dense-rib structure, which makes the structural space waste larger. Since the light steel dense-rib structure and the steel frame structure working principle cannot match, even if the waste of space is not considered and only the realization of forming the exterior structure of the house is considered, the two structures cannot be directly combined. If there is a structure that can give play to the high space utilization rate and other advantages of the frame structure and can conveniently form a complex roof structure, and can also be conveniently assembled, it is the purpose of the present invention.
