Abstract
The invention discloses a support structure for a long-span steel roof truss, and is characterized in that one end of the long-span steel roof truss is fixedly supported by a pillar, while the other end is provided with a sliding support movably supported by a shoulder beam of the pillar; the sliding support consists of a crest slab, a spherical slide block, a base and a base plate; the base is arranged on the base plate in the shape of basin, baffle plates are arranged on two sides of the base plate, the crest slab is clasped on the base the middle of which is provided with the spherical slide block and a seal ring, and tetrafluoroethylene plates are arranged above and below the spherical slide block respectively. The support structure has the characteristics of reasonable design, simple structure, convenient construction and installation, and reliable performance compared with the prior art; therefore, the support structure not only satisfies extension and retraction caused by temperature change of the long-span steel roof truss, but also greatly reduces construction investment and quickens the construction progress.
Description
Technical field
The present invention relates to the building iron roof truss structure, specifically a kind of wide span steel roof frame supporting construction.
Background technology
According to the design specifications of construction steel structure, when horizontal (being the span direction of steel roof truss) of steel-structure factory building surpasses 150m, should Temperature Joint be set, to discharge the thermal stresses that produces owing to the steel roof truss overlength at suitable colonnade place.At present, design for horizontal overlength (greater than 150m) wide span single layer steel work industrial premises, generally all adopt and locate to be provided with shrinkage joint (the factory building lateral length of both sides, shrinkage joint is less than 150m) in position, superstructure is then established twin columns in the both sides of seam, foundation then will be beaten double-row pile, be established associating cushion cap and two rim of a cup, by code requirement certain shrinkage joint width is set between the double pillar, the steel roof truss of both sides, shrinkage joint is thrown off, and lateral length is not more than 150m, to satisfy the requirement that discharges the steel roof truss thermal stresses in the standard.The shortcoming that prior art exists is owing to set up an organ timbering, has not only increased the expense of steel column, steel concrete cushion cap and pile foundation, but also has increased construction and mounting hardness, long construction period.
Summary of the invention
The objective of the invention is a kind of wide span steel roof frame supporting construction of designing at the deficiencies in the prior art, it adopts the benzvalene form slip support abutment, do not need to establish twin columns and beat double-row pile with the basis in the both sides at shrinkage joint, and associating cushion cap and two rim of a cup are set, and significantly reduced construction investment, shorten construction period, not only satisfied wide span steel roof frame because of stretching that variations in temperature causes, and supporting construction is simple, and is easy for installation, dependable performance.
The technical scheme that realizes the object of the invention is: a kind of wide span steel roof frame supporting construction, characteristics are that an end and the pillar of wide span steel roof frame is fixed bearing, and the shoulder beam that the other end is provided with sliding support and pillar is an expansion bearing.
Described sliding support is made up of top board, sphere slide block, base and base plate, and base is that peviform is arranged on the base plate, and it is affixed by bolt that the base plate both sides are provided with baffle plate, and top board snaps onto on the base, is provided with sphere slide block and sealing ring in the middle of it; The upper and lower tetrafluoro plate that is respectively equipped with of sphere slide block is provided with the steel slide plate between tetrafluoro plate and top board, be provided with tetrafluoro plate, steel slide plate between base and base plate.
Described tetrafluoro plate is plane or sphere.
The present invention is reasonable in design, and is simple in structure, compared with prior art has construction, easy for installation, and the characteristics of dependable performance have not only satisfied wide span steel roof frame because of stretching that variations in temperature causes, and significantly reduced construction investment, have accelerated construction speed.

Fig. 2 is a sliding support structural representation of the present invention
Fig. 3 is a scheme of installation of the present invention
The specific embodiment
Consult accompanying drawing 3, the present invention installs like this: an end that the top board 2 of sliding support 1 is fixedly connected on wide span steel roof frame 15 by bolt 5, base plate 14 is fixedly connected on the shoulder beam 18 by bolt 13, the other end of wide span steel roof frame 15 then is fixedly connected on the pillar 17, and make between wide span steel roof frame 15 1 ends be provided with sliding support 1 and the pillar 17 certain shrinkage joint width to be arranged, with the requirement of release steel roof truss thermal stresses in the design specifications that satisfies construction steel structure.
