Disclosure of Invention
In order to improve the security performance of steel construction node when installation, this application provides an assembled steel construction node.
The application provides an assembled steel structure node adopts following technical scheme:
the utility model provides an assembled steel structure node, includes node short column and case type post, be connected with the node flange on the node short column, be connected with the column flange on the case type post, waist type hole has been seted up on the node flange, be provided with the bolt on the node flange, the pole portion of bolt slides and sets up in waist type hole, threaded connection has the nut in the pole portion of bolt, the nut is located the one side that the bolt head was kept away from to the node flange, set up the spread groove that supplies bolt pole portion to stretch into on the lateral wall of column flange.
By adopting the technical scheme, when the node short column and the node flange are produced in a factory, the rod parts of the bolts are directly inserted into the waist-shaped holes respectively, and the bolts are connected with the nuts respectively in a threaded manner. Treat the assembled steel construction node of this application when assembling on the building site, only need align with spread groove and waist type pore on the post flange earlier, the bolt in the waist type pore of sliding again, until the bolt immigration spread groove in the waist type pore can, screw bolt, nut at last to through node flange and post flange connected node short column and box type post. Through the structure, the bolts and the nuts are connected to the node flanges when being assembled in a factory, so that when workers work in the air, the bolts do not need to be taken out and inserted into the node flanges, safety accidents that the bolts fall from the high altitude due to the execution of the actions are avoided, and the safety performance of the steel structure nodes during installation is improved. Simultaneously, when the bolt is preassembled in the mill, can screw bolt, nut to only reserving the small segment bolt sliding space for during the staff's operation on the building site, only need rotate less number of turns with bolt and nut, saved the equipment time, improved the packaging efficiency of assembled steel structure node.
Optionally, the node flange is provided with a linkage piece in a sliding manner, the linkage piece is provided with a light hole for sliding of the bolt rod portion, the linkage piece is connected with a limiting hook in a rotating manner, the limiting hook is connected with a limiting torsion spring for driving the limiting hook to rotate towards the direction close to the node flange, the node flange is provided with a limiting groove for being clamped and matched with the limiting hook, and when the limiting hook is matched with the limiting groove in a clamping manner, the bolt is in contact with the hole wall of the waist-shaped hole, which is far away from the short node column.
Through adopting above-mentioned technical scheme, when the pre-installation bolt in the mill, pass unthreaded hole and waist type hole with the bolt, again with nut threaded connection, then cooperate spacing hook and spacing groove joint, spacing torsional spring has restricted the tip of spacing hook and has deviate from the spacing groove. The limiting hook and the limiting groove play a limiting role, so that each bolt is limited by the linkage part to be in contact with the wall of the kidney-shaped hole far away from the node short column. When the box-shaped column and the node short column are connected, if the bolt slides along the extending direction of the waist-shaped hole to be in contact with the wall of the waist-shaped hole close to the node short column, the head of the bolt can cause that the column flange cannot be attached to the node flange. Through above-mentioned structure, before having restricted node flange and the connection of post flange, each bolt slides along the extending direction in waist type hole to when making staff's connection box type post and node short column, need not to remove each bolt to the direction of keeping away from node short column.
