Built-up connection structure and built-up connection method for roof support and I-steel purlins

Abstract

The invention relates to the technical field of arrangement of steel structure roof support, and discloses a built-up connection structure and a built-up connection method for roof support and I-steel purlins. The built-up connection structure is provided with a plurality of steel roof truss structures and a plurality of roof support structures which are connected into a net-shaped connection structure. Each steel roof truss structure comprises a steel roof truss upper chord and a purlin which are perpendicularly connected in a cross mode. Four corners of the panel point where each purlin is connected with each steel roof truss upper chord are connected with a roof support rod in an inclined mode through a structural steel piece and a connecting plate. Each roof support structure comprises a connecting beam and a purlin which are perpendicularly connected in an overlapped mode. Four corners of the panel point where each purlin is connected with each connecting beam are connected with the roof support structure in an inclined mode through a connecting plate. According to the built-up connection structure and the built-up connection method for the roof support and the I-steel purlins, the purlins can concurrently serve as pressure levers so as to prevent the roof upper chords from being unstable along the side direction. Meanwhile, the purlins and the connecting beams can further and concurrently serve as tie bars of the roof support. The area of the roof support is divided into sizes with good economical efficiency and applicability. The built-up connection structure is convenient to arrange, simple in structure, easy to machine and low in manufacture and machining cost.

Description

technical field [0001] The invention relates to the technical field of steel structure roof support arrangement, in particular to a combined connection structure and combined connection method of roof supports and I-shaped steel purlins. Background technique [0002] At present, in the field of steel structure roof support structure layout, the roof support system and roof I-steel purlins are generally set separately, and the I-steel purlins bear the self-weight load, wind load and roof ventilator load transmitted from the roof panel. The roof support can ensure the space work of the roof structure, improve its overall rigidity, bear and transmit the horizontal force, avoid the lateral instability of the roof truss pressure rod, and ensure the stability and convenience of the structure installation. However, in some cases, setting the roof support system and I-beam purlins separately can significantly increase the amount of roof materials, and the technical and economic indi...

Problems solved by technology

However, in some cases, setting the roof support system and I-beam purlins separately can significantly increase the amount of roof materials, and the technical and economic indicators are not good, so an improvement plan is urgently needed
