Abstract
The utility model relates to a large steel structure building, in particular to a large steel structure building temperature stress relieving structure. The large steel structure building temperature stress relieving structure comprises steel erecting beams and longitudinal components, and a connecting node of each longitudinal component and each steel erecting beam is an oblong-hole-structure node which can slide. When no temperature expansion joint is arranged on the large steel structure building temperature stress relieving structure, through an oblong-hole high-strength bolt node with high and strong deformation performance, temperature stress of a steel structure system is effectively relieved, and an aim of preventing a large number of steel structure beam column nodes from brittle failure is achieved. One-door type steel beams and corresponding foundations can be reduced, and the complex joint structure is avoided. According to the oblong-hole technology, the large steel structure building temperature stress relieving structure is relatively simple to manufacture in a factory and relatively convenient to install, and the only difference is that the holes are oblong.
Description
Technical field
The utility model relates to the large-scale steel structure building, specifically is a kind of large-scale steel structure building thermal stresses releasing structure.
Background technology
Because the premium properties of self, steel work has been widely used in engineerings such as factory building, storehouse, sports palace, exhibition hall, airport hangar, but for large span, multispan number, high facade large-scale steel structure system, present design specifications development lags behind.Temperature section length (spacing at shrinkage joint) according to " Code for design of steel structures " (GB 50017-2003) 8.1.5 one storey house and open-air structure is no more than 220m to heating house and house, non-heating region longitudinal temperature section, walking crosswise temperature section is no more than the 120m(capital and just ties) and 140m(capital hinge knot), otherwise to consider the influence of thermal stresses temperature deformation.Also occur some unfavorable factors (technological requirement, pipeline complicated layout, facade are not attractive in appearance as not satisfying, drainage system complexity etc.) accordingly but deformation joint is set, this is the size of limit structural greatly just.And large-scale and ultra-large type steel structure system is an important directions of futurity industry, civilian construction development, and the research of this class formation under temperature variations is also just seemed particularly important.
The utility model content
The utility model aims to provide a kind of large-scale steel structure building thermal stresses releasing structure, to solve thermal stresses and the temperature deformation problem of large-scale steel structure system under the situation that the shrinkage joint is not set.
The technical scheme that the described problem that solves the utility model adopts is:
A kind of large-scale steel structure building thermal stresses releasing structure comprises truss-steel beam, longitudinal member, and the connected node of described longitudinal member and truss-steel beam is slotted hole structure node slidably.
Further, described slidably slotted hole structure node comprises on the connection end plate that welds on the longitudinal member, the truss-steel beam ribbed stiffener and is fixedly coupled clamping plate, has corresponding vertical slotted hole on described connection end plate and the connecting cleat; Described longitudinal member and described truss-steel beam are connected by bolt slidably by described vertical slotted hole.
Adopt the utility model of above technical scheme, compared with prior art, its beneficial effect is: under the situation that Temperature Joint is not set, utilize slotted hole modification high-strength bolt node, realized effectively releasing the steel structure system thermal stresses, avoided the purpose of a large amount of steel-structure beam-column node generation brittle fractures.Can reduce a Pin portal frame beam and corresponding basis, and avoid complicated seam construction.The slotted hole technology is fairly simple at produce in factory, installation is also more convenient, and different only perforates is Long Circle.After sliding and be out of shape, bolt needs hardly to repair.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: truss-steel beam 1, connecting cleat 2 connects end plate 3, longitudinal member 4, vertical slotted hole 5, slidably bolt 6.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment, and purpose only is to understand better the utility model content.
Referring to Fig. 1, this large-scale steel structure building thermal stresses releasing structure, its structural member comprises truss-steel beam 1 and longitudinal member 4, be welded with connection end plate 3 at longitudinal member 4, ribbed stiffener at truss-steel beam 1 fixedly has connecting cleat 2, connects to have corresponding vertical slotted hole 5 on end plate 3 and the connecting cleat 2; Be connected by bolt 6 slidably by the vertical slotted hole 5 that is connected on vertical slotted hole 5 and the connecting cleat 2 on the end plate 3 between longitudinal member 4 and the truss-steel beam 1.
Above-mentioned longitudinal member 4 mainly contains members such as purlin wall beam, crane girder, the connected node of these members and truss-steel beam 1 all adopts slidably slotted hole bolt fastening structure, simultaneously, also the roof panel on the truss-steel beam 1, shingle nail can be processed into the structure that can stretch, then whole mill construction can come release temperature stress by the sliding extension of these joint structures when work.
The length of above-mentioned vertical slotted hole 5 can be 0.080m.
More than disclosed be specific embodiment of the utility model only, but the utility model is not limited thereto, any those skilled in the art can think variation, all should drop within the protection domain of the present utility model.
Claims (2)
1. large-scale steel structure building thermal stresses releasing structure comprises truss-steel beam, longitudinal member, it is characterized in that, the connected node of described longitudinal member and truss-steel beam is slotted hole structure node slidably.
