Building system combined truss with steel shaped like Chinese character 'zhi'

Abstract

The invention provides a building system combined a truss with steel shaped like a Chinese character 'zhi'. The building system is used for constructing a warehouse or a plant and comprises rigid frame column beams, middle columns, purlines, cornice supporting units, wall frame columns, truss type secondary beams and truss type joists. The rigid frame column beams are connected with the cornice supporting units and provided with the middle columns; the purlines are arranged between rigid frame beams and comprise cornice purlines and roof purlines; the cornice supporting units are arranged between the cornice purlines and connected with one ends of the rigid frame beams; the wall frame columns are parallelly arranged between the rigid frame columns; the truss type secondary beams are parallelly arranged between the rigid frame beams and located below the purlines; and the two ends of the truss type secondary beams are connected with the truss type joists correspondingly. According to the building system combined the truss with the steel shaped like the Chinese character 'zhi', all kinds of components with the cost performance ratio are economically combined, characteristics of the components are fully exerted, so that a plant or warehouse building within a certain specification and load range has small deflection and the low comprehensive construction cost, the steel content isgreatly reduced, and construction is convenient and fast.

Description

technical field [0001] The invention relates to the field of industrial and civil buildings, in particular to a truss and its section steel combined building system. Background technique [0002] Portal frame light steel structure is widely used in factory buildings and warehouse buildings. Among them, the light steel structure of the portal frame uses section steel to make the portal frame, cold-formed thin-walled steel for purlins and wall beams, and profiled steel plates or lightweight sandwich panels for roof and wall enclosure structures. On the one hand, the traditional solid-web H-shaped steel beams and columns have strict requirements on the height-to-thickness ratio and width-to-thickness ratio of the slab in the current code, so the slab thickness is usually relatively large, so the steel content of the entire building is relatively high. [0003] In addition, in the current light steel structure of portal frame, the span of purlins in many warehouses or workshops...

Problems solved by technology

Furthermore, the cross-section of long-span purlins is usually large, which increases the steel content of the purlins; the long-span purlins on the wall are prone to deformation, and the deflection is large, which makes it troublesome to install windows and wall panels on the wall.
