Assembly type equal-length vertical web truss slope roof beam system structure

Abstract

The invention discloses an assembly type equal-length vertical web truss slope roof beam system structure which can obtain the advantage of a high space utilization rate of a framework steel structurebuilding, also can realize a relatively complex roof structure, and is conveniently manufactured. The assembly type equal-length vertical web truss slope roof beam system structure comprises each slope truss beam, each oblique crossed truss beam between adjacent slope surfaces, two ridge truss beams which are crossed relative to the tops of the slope surfaces, truss joints crossed with a truss, and the like. The assembly type equal-length vertical web truss slope roof beam system structure is simple in structure and is convenient in mounting.

[0002] Compared with the light steel dense rib structure residence, the frame steel structure residence is popular because of its large bearing capacity, good isolation, no sense of tremor, and the sloping roof structure can realize internal voids and can effectively use the space, etc., but the frame steel structure is in It is difficult to complete complex slope roofs, especially multi-slope roof structures. The steel beams of the frame steel structure are generally H-shaped steel beams. The H-shaped steel beams are used to form a hollow roof frame with a large span. The purlins constitute the external support structure of the roof. When realizing a complex multi-slope roof structure, each H-shaped steel beam often has multi-angle and multi-directional three-dimensional space intersections at the joints, so that the wings and webs of each H-shaped steel beam Both cannot be connected in the same plane, which makes the shape of the end face of the joint connection member very complicated, which makes it difficult to make the end face cutout at the beam joint or the joint connection on site. In order to meet the rigid connection requirements, the web of each beam must be realized. The connections between the plates and the flanges are respectively formed, so it is very inconvenient to realize whether it is the manufacture of the end faces of the components, the on-site welding between the components, or the joints made separately

The thin-walled steel used in the light-steel dense rib structure is composed of thin-walled steel through self-tapping screws to form a triangular truss called a girder beam when forming the roof. Triangular trusses of different sizes and angles are used to pass through dense Arrangement constitutes the support for the roof, so that the light steel dense rib structure is not sensitive to the complexity of the roof. The disadvantage is that the structure from the lowest point of the slope is occupied by the dense rib structure, which wastes a lot of structural space.

Since the working principle of the light steel dense rib structure and the steel frame structure cannot match, it is impossible to directly combine the two structures even if the realization of the outer structure of the house is not considered.
