Background

In the steel structure building, the connection between the wind-resistant columns and the roof truss of the steel gable wall has mature structural nodes (as shown in fig. 1-2), and the structural nodes can meet the following two requirements: firstly, can transmit wind load, seismic action etc. that steel gable anti-wind post bore to the roof truss system, secondly, the vertical load that the roof truss bore can not transmit to anti-wind post like dead weight, wind load etc. also the vertical deformation of roof truss can not receive the restriction of anti-wind post. For structures that do not span much, this type of node is applicable. Along with society and technical development in recent years, the span in steel construction workshop is bigger and bigger, reaches about 150m even, and at this moment, the roof truss will produce considerable deformation under vertical load, and simultaneously, the horizontal load that steel gable anti-wind post transmitted for the roof truss system has also surpassed the bearing capacity of traditional structure node greatly, consequently for satisfying the atress requirement of this type of large-span steel construction, need design a neotype gable post anti-deformation reinforcement method.

Referring to fig. 3-5, the present invention provides a technical solution: a wind-resistant column and roof connecting node suitable for a large-span steel structure roof comprises a steel connecting rod 3 arranged between a steel roof truss 1 and a steel gable wind-resistant column 2; two ends of the steel connecting rod 3 are respectively connected with the steel roof truss 1 and the steel gable wind-resistant column 2 in a rotating way.

Further, the steel connecting rods 3 are provided with two groups, and the two groups of steel connecting rods 3 are respectively arranged at the upper end and the lower end of the wind-resistant column 2 of the steel gable wall.

Furthermore, both ends of each group of steel connecting rods 3 are fixed with the connecting plate by pin shafts.

Furthermore, two pin shafts are arranged on each group of steel connecting rods 3, namely a first connecting pin shaft 4 and a second connecting pin shaft 5.

Further, the steel roof truss 1 and the steel gable wind-resistant column 2 are respectively provided with a roof truss connecting plate 6 and a gable column connecting plate 7 at positions corresponding to the steel connecting rod 3.

Furthermore, one end of each group of steel connecting rods 3 is rotatably connected with the gable column connecting plate 7 through a first connecting pin shaft 4, and the other end of each group of steel connecting rods 3 is rotatably connected with the roof truss connecting plate 6 through a second connecting pin shaft 5.

Further, the installation method of the steel connecting rod 3 is as follows: the steel roof truss 1 and the steel gable wind-resistant column 2 are manufactured, installed and then provided with the steel connecting rod 3 respectively, the first connecting pin shaft 4 and the second connecting pin shaft 5 at the two ends of the steel roof truss are connected with the gable column connecting plate 7 and the roof truss connecting plate 6 respectively, and the steel roof truss 1 and the steel gable wind-resistant column 2 are connected through the steel connecting rod 3.

Further, when the steel roof truss 1 generates vertical displacement under the action of vertical load such as dead weight and wind pressure, the steel connecting rod 3 drives the steel gable wind-resistant column 2 to generate horizontal displacement deformation.

Further, the steel gable wind-resistant post 2 is through setting for the length of steel connecting rod 3 with the connected node of steel roof truss 1 for when steel roof truss 1 takes place great vertical deformation, the level of steel gable wind-resistant post 2 is less to the displacement, thereby reduces steel roof truss 1 and takes place the adverse effect to steel gable wind-resistant post 2 when great deformation.

The working principle is as follows: this scheme is at steel roof truss 1 and steel gable anti-wind post 2 and is makeed the installation respectively and accomplish back installation steel connecting rod 3, is connected with gable post connecting plate 7, roof truss connecting plate 6 respectively through the first connecting pin axle 4 and the second connecting pin axle 5 at its both ends, is connected the completion with steel gable anti-wind post 2 through steel connecting rod 3 with steel roof truss 1.

The operation mechanism of the structural joint of the steel connecting rod 3 is as follows: under vertical load such as wind load, effect such as dead weight, steel roof truss 1 produces vertical displacement delta 1, it warp delta 2 to the displacement to drive steel gable anti-wind post 2 through steel connecting rod 3 to take place the level, derive through the formula that the lower graph shows, it is very little to know delta 2/delta 1 numerical value, also when steel roof truss 1 takes place great displacement delta 1, the level of steel gable anti-wind post 2 is still less to displacement delta 2's numerical value, this numerical value is in steel gable anti-wind post 2's normal operating range, and then can not lead to steel gable anti-wind post 2 internal force to take place great change.

The derivation formula is as follows:
