Light steel roof system with corner brace as purlin fulcrum

Abstract

The present invention disclosed a light steel roof system that supports pulling bar as a pentage fulcrum.Including steel beams, puppets, support, tension, ripples, and connecting boards. The top surface of the wing edge of the steel beam is fixed with a cricket.There is a connection board between the two sides and the abdominal plate, respectively, and the ends of the puppets are connected to the support, and the support is connected between the bar and the connecting board;The described tension is connected between the two adjacent strips between the two adjacent strips or between the two adjacent bars between the two adjacent strips.The present invention forms a solid spatial force system. At the same time, it can reduce the computing length of the surface and out -of -face, which is conducive to the design of the bars and improves the overall stress performance of the space of the roof system.In the design of light steel structure roofs composed of 拉, support, and pull strips.

Description

technical field [0001] The invention relates to a light steel roof purlin system, in particular to a light steel roof system with a corner brace as a purlin fulcrum, which can be widely used in the roof purlin system of light steel workshops. Background technique [0002] In the light steel workshop, the whole building is composed of structural system and envelope system. The structural system consists of portal rigid frame, façade support and roof horizontal support system to form a stable frame. The enclosure system consists of a roof system and a wall system, which are attached to the structural system to form a complete light-weight steel structure workshop that meets the functions of use. [0003] In the roof envelope system, it is mainly composed of purlins, corner braces, braces, and roof panels. The roof panel is fixed on the purlins with self-tapping screws or fixed seats, and the purlins are fixed on the portal rigid frame through the purlin brackets. The edge i...

Problems solved by technology

[0009] In order to overcome the disadvantages of the existing purlin system, such as the weak local stiffness of the purlins at the connection points of the braces and the looseness of the braces, and the shortcomings of no restraint stiffness outside the plane of the connection of the corner brace purlins, the present invention proposes a corner brace brace as the purlin fulcrum The light steel roof system: by improving the connection node method of the braces, the axial stiffness of the braces is increased, and the relaxation of the braces is reduced; the out-of-plane displacement of the purlins is restricted by setting braces at the connection of the corner purlins, and the lateral direction of the purlins is improved. Rigidity can meet the assumed conditions of the corner brace as the fulcrum of the purlin, form a space force system, and effectively reduce the effective calculation length of the purlin
