Embodiment Construction

[0010] The present invention will be further described below in conjunction with the examples, and the purpose is only to better understand the content of the present invention.

[0011] see figure 1 , this large-scale steel structure building temperature stress relief structure, its structural parts include a steel frame beam 1 and a longitudinal member 4, a connection end plate 3 is welded on the longitudinal member 4, and a connection end plate 3 is fixed on the reinforcement rib of the steel frame beam 1 The splint 2, the connecting end plate 3 and the connecting splint 2 are respectively provided with corresponding longitudinal oblong holes 5; The oblong holes 5 are connected by slidable bolts 6 .

[0012] The above-mentioned longitudinal members 4 mainly include purlin wall beams, crane beams and other members. The wall panels are processed into a stretchable structure, and the entire plant structure can release temperature stress through the sliding and stretching of ...

Abstract

The invention relates to a large-size steel structure building, in particular to a temperature stress releasing structure of a large-size steel structure building. Members of the structure comprise a steel beam, and a longitudinal member. A connected node between the longitudinal member and the steel beam is a slidable slotted hole structure node. Under the condition that a temperature expansion joint is not arranged, a slotted hole variant high strength bolt node is utilized to effectively release the temperature stress of a steel structure system. The problem of brittle failure of a large number of beam-column nodes of the steel structure is avoided. A door type steel beam and corresponding foundation are reduced and a complex joint structure is avoided. Slotted hole technology is simple in manufacture in a factory, and convenient to assemble, an opening is in the shape of a long circle. Bolt is hardly in need of repair after slide deformation.

Description

technical field [0001] The invention relates to a large steel structure building, in particular to a large steel structure building temperature stress release structure. Background technique [0002] Due to its excellent performance, steel structures have been widely used in factories, warehouses, gymnasiums, exhibition halls, airport hangars and other projects. However, for large-span, multi-span, and high-facade large-scale steel structure systems, the development of current design specifications lags behind. . According to "Code for Design of Steel Structures" (GB 50017-2003) 8.1.5, the temperature section length (distance of expansion joints) of single-storey houses and open-air structures shall not exceed 220m for heating houses and houses in non-heating areas. The temperature section shall not exceed 120m (column top rigid junction) and 140m (column top hinged connection), otherwise the influence of temperature stress and temperature deformation shall be considered. ...
