Abstract
The invention discloses a dislocation-free expansion joint node for box type profiled steel sheets. The dislocation-free expansion joint node comprises a rigid connecting strip and two transitional connecting members, wherein the transitional connecting members are used for the end surfaces of the box type profiled steel sheets respectively arranged at two sides of an expansion joint, one end of the rigid connecting strip is fixed on one transitional connecting member and used as a fixing end, and the other end of the rigid connecting strip horizontally extends out along the longitudinal direction of the box type profiled steel sheets, is used as a free end and extends into a longitudinal sliding chute in the other transitional connecting member, so that the free end of the connecting strip can move along the longitudinal sliding chute. According to the dislocation-free expansion joint node, the vertical dislocation at the expansion joint of the two box type profiled steel sheets can be eliminated, meanwhile, free expansion and withdrawal of the longitudinally adjacent two box type profiled steel sheets can be ensured, and therefore the phenomenon that the two box type profiled steel sheets at two sides of the expansion joint are vertically staggered and pulled apart is effectively avoided on the premise of ensuring that box type profiled steel sheets freely expand and withdraw, and therefore a roof boarding can be effectively prevented from leaking.
Description
Technical field
The present invention relates to a kind of building unit node, particularly a kind of box-shaped profiled sheet dislocation-free shrinkage joint node.
Background technology
At present, the box-shaped profiled sheet has been widely used in the wide span house cap load steel structure, shown in Fig. 1～4, existing box-shaped profiled sheet steel roof system need not to arrange purlin, it generally comprises truss 1, box-shaped profiled sheet 2 and roof panel and heat-preservation cotton (both are not shown in FIG. afterwards) etc., in the ordinary course of things, the span of box-shaped profiled sheet can reach more than 15 meters, existing box-shaped profiled sheet 2 is specifically docked up and down with down-pressing type steel plate 22 by upper profiled sheet 21 and forms, referring to Fig. 3,4, according to box-shaped profiled sheet actual loading situation, can in the box-shaped profiled sheet, with the I-shaped state H shaped steel 3 be set, to improve its bearing capacity.
Because single box-shaped profiled sheet in the longitudinal direction Chang Buneng satisfies the length requirement of roof system, therefore often need to namely vertically splice the box-shaped profiled sheet at length direction, two vertical adjacent box-shaped profiled sheets adopt two cantilevered fashions usually in the end, and between the docking termination of two box-shaped profiled sheets, leave shrinkage joint 4, in order that satisfying the box-shaped profiled sheet expands with heat and contract with cold and the relative displacement that produces from the variations in temperature of experiencing, referring to Fig. 2, at present, in work progress, processing for the shrinkage joint generally only limits to preset clearance as the shrinkage joint, and no longer take other measure, therefore, can produce following weak point: because the rigidity of box-shaped profiled sheet is gentleer, carry at wind, surface settlement, the box-shaped profiled sheet of both sides, shrinkage joint easily produces vertical dislocation (or claiming vertical dislocation) under the active forces such as inclination and seismic load, so that can directly pull roof panel fixed thereon, when serious even can pull roof panel, make roof panel impaired and produce Seepage.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, construction cost is lower, not only can eliminate the box-shaped profiled sheet of both sides in the vertical dislocation at place, shrinkage joint, but also can guarantee the box-shaped profiled sheet dislocation-free shrinkage joint node that two vertically adjacent box-shaped profiled sheets in the vertical can free-extension.
Purpose of the present invention realizes by following technical measures: a kind of box-shaped profiled sheet dislocation-free shrinkage joint node, it is characterized in that: comprise be rigidly connected bar and two transition pieces, described transition piece is used for being separately positioned on the end face of the box-shaped profiled sheet that is positioned at the both sides, shrinkage joint, one end of the described bar that is rigidly connected is fixed therein on the transition piece, this end is as fixed end, the other end vertically stretches out and stretches in the vertical chute that has on another transition piece as free end along the box-shaped profiled sheet, and the free end that makes connection strap longitudinally chute moves.
