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, box-shaped profiled sheet has been widely used in wide span house cap load steel structure, as shown in Fig. 1～4, existing box-shaped profiled sheet steel roof system is without purlin is set, 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 and forms up and down with down-pressing type steel plate 22 by upper profiled sheet 21, referring to Fig. 3, 4, according to box-shaped profiled sheet actual loading situation, can in box-shaped profiled sheet, with I-shaped state, H shaped steel 3 be set, to improve its bearing capacity.
Due to single box-shaped profiled sheet in the longitudinal direction Chang Buneng meet the length requirement of roof system, therefore often need to splice box-shaped profiled sheet on length direction is longitudinal, two longitudinal adjacent box-shaped profiled sheets adopt two cantilevered fashions conventionally in end, and leave shrinkage joint 4 between the docking termination of two box-shaped profiled sheets, in order that meeting 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, generally only limit to preset clearance as shrinkage joint for the processing at shrinkage joint, and no longer take other measure, therefore, can produce following weak point: because the rigidity of box-shaped profiled sheet is more soft, carry at wind, surface settlement, under the active forces such as inclination and seismic load, the box-shaped profiled sheet of both sides, shrinkage joint easily produces vertical dislocation (or claiming vertical dislocation), 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 shrinkage joint place, but also can ensure the box-shaped profiled sheet dislocation-free shrinkage joint node that two longitudinally adjacent box-shaped profiled sheets in the vertical can free-extension.
Object 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 for being separately positioned on the end face of the box-shaped profiled sheet that is positioned at both sides, shrinkage joint, one end of the described bar that is rigidly connected is fixed therein on a transition piece, this end is as fixed end, the other end longitudinally stretches out and stretches into as free end in the longitudinal chute having on another transition piece along box-shaped profiled sheet, the free end that makes connection strap longitudinally chute moves.
The present invention by two longitudinally the shrinkage joint place between adjacent box-shaped profiled sheets add connection strap and be flexibly connected the termination of two box-shaped profiled sheets, can eliminate vertical (being the Z-direction shown in Fig. 7) dislocation at shrinkage joint place of two box-shaped profiled sheets, can ensure again that two longitudinally adjacent box-shaped profiled sheets can free-extension on longitudinally (be the X shown in Fig. 7 to) simultaneously, therefore, ensureing under the prerequisite of box-shaped profiled sheet free-extension, the phenomenon of effectively having avoided roof panel to be pulled due to the vertical changing of the relative positions of both sides, shrinkage joint box-shaped profiled sheet, thereby can effectively prevent roof panel generation seepage.
