Problems solved by technology

[0003] Since a single box-shaped profiled steel plate often cannot meet the length requirements of the roof in the length direction, it is often necessary to splice box-shaped profiled steel plates in the length direction, that is, in the longitudinal direction. Two longitudinally adjacent box-shaped profiled steel plates are usually The form of double cantilever is adopted, and there is an expansion joint 4 between the butt ends of the two box-shaped profiled steel plates, in order to meet the relative displacement of the box-shaped profiled steel plate itself due to thermal expansion and contra

Example Embodiment

[0029] Example 1

[0030] like Figures 5 to 10 As shown, it is a box-shaped profiled steel plate without dislocation expansion joints of the present invention, including rigid connecting strips and two transition connecting pieces, the rigid connecting strips are steel strips 5, and the transition connecting pieces are used to be respectively arranged on the two expansion joints 4. On the end faces of the side box-shaped profiled steel plates 6 and 7, one end of the steel bar 5 is fixed on one of the transition pieces, and this end is used as the fixed end, and the other end extends into the other side along the longitudinal direction of the box-shaped profiled steel plate as a free end. In the longitudinal chute on a transition piece, the free end of the steel bar 5 can move along the longitudinal chute to meet the longitudinal expansion and contraction of the box-shaped profiled steel plate, see Figure 7 , which can eliminate the vertical direction of the two box-shaped p...

Example Embodiment

[0034] Example 2

[0035] The difference between this embodiment and Embodiment 1 is that the H-shaped steel in the I-shaped state is not provided in the box-shaped profiled steel plates on both sides of the expansion joint, and the end faces of the box-shaped profiled steel plates on both sides of the expansion joint are provided with Sealing plate, the connecting side of the lug plate is connected to the sealing plate to realize the connection between the lug plate and the box-shaped profiled steel plate. At this time, the ear plate is perpendicular to both the sealing plate and the web of the H-beam as the transition piece.

Example Embodiment

[0036] Example 3

[0037] The difference between this embodiment and Embodiment 1 is that H-shaped steel is provided on one of the box-shaped profiled steel plates on both sides of the expansion joint, and H-shaped steel is not provided on the other side of the box-shaped profiled steel plate. The end face of the box-shaped profiled steel plate is provided with a sealing plate, and the other side of the box-shaped profiled steel plate is provided with an H-shaped steel in an I-shaped state. The connection side of one ear plate is fixed on the sealing plate, and the connection of the other ear plate The side is butt-fixed with the web of the H-beam in the box-shaped profiled steel plate.

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 [0001] The invention relates to a building component node, in particular to a box-shaped profiled steel plate non-dislocation expansion joint node. Background technique [0002] At present, box-shaped profiled steel plates have been widely used in large-span roof load-bearing steel structures, such as Figures 1 to 4 As shown in the figure, the existing box-shaped profiled steel roof does not need to be provided with purlins. It generally includes a truss 1, a box-shaped profiled steel plate 2, a roof panel and insulation cotton (the latter two are not shown in the figure), etc. In general The span of the box-shaped profiled steel plate can reach more than 15 meters, and the existing box-shaped profiled steel plate 2 is specifically formed by the upper and lower profiled steel plates 21 and the lower profiled steel plate 22 butted up and down, see image 3 , 4 , According to the actual stress situation of the box-shaped profiled steel plate, the H-shaped ste...
