Detailed Description

The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.

The embodiment is as follows: an assembly structure of a steel structure frame node is shown in figures 1-5 and comprises an upright post 1 and a cross beam 2, wherein a connecting portion 3 capable of being connected with the cross beam 2 in an inserting mode is arranged on the upright post 1, a matching portion 4 capable of being matched and connected with the connecting portion 3 in an inserting mode is arranged at one end of the cross beam 2, the connecting portion 3 comprises a first inserting portion 3a and a first fixing portion 3b connected to the first inserting portion 3a and far away from one side of the upright post 1, a first inserting groove 3a1 is further formed in one side, far away from the upright post 1, of the first fixing portion 3a, a first inserting head 3b1 is arranged on one side, far away from the upright post 1, of the first inserting portion 4a and a second inserting portion 4a capable of being abutted against the first fixing portion 3b1, a second inserting groove 4a1 into which the first inserting groove 3a1 can be formed in one side, facing the upright post 1, the first inserting portion 3b1 and a second inserting head 4b1 can be abutted against the groove wall of the first inserting portion 4a, and the first inserting head 4a fixing portion 4b can be matched with the fixing portion of a fixing assembly component, and the connecting portion 4b which can be sequentially positioned and can be abutted against the first inserting portion 4b, and the second fixing portion 4b of the connecting portion 4b, and the connecting portion 4b of the steel structure, and the fixing portion 4 b. This assembly structure of steel structure frame node is through inserting two 4b1 of spliced eye on the two 4b of fixed part to inserting groove 3a1, inserting 3b1 of spliced eye on the one 3b of fixed part is inserted to inserting groove two 4a1, and make fixed part 3b and two 4b offsets and lean on, thereby realize the vertical fixed between cooperation portion 4 and the connecting portion 3, thereby rethread fixed subassembly 6 runs through fixed part 3b and two 4b of fixed part in proper order and realizes the horizontal fixed between connecting portion 3 and the cooperation portion 4, thereby it is fixed to accomplish the installation of crossbeam 2 between stand 1 node.

Further, this assembly structure of steel structure frame node still includes one end and 2 fixed other ends mutually of crossbeam and the backup pad 5 of stand 1 fixed mutually, and specifically, fixed mode all adopts the fastener fixed, has the tray 5a that can lean on with fixed subassembly 6 counterbalance on the backup pad 5. Install backup pad 5 to fixed subassembly 6 male one side, at first can be with the joint strength between further reinforcement crossbeam 2 and the stand 1 through backup pad 5, the tray 5a on the backup pad 5 can support with the fixed subassembly 6 that runs through fixed part 3b and two 4b of fixed part in proper order and lean on simultaneously to further carry on spacingly to the vertical position of fixed subassembly 6, thereby can prevent that fixed subassembly 6 from taking place because of the not firm not hard up condition of fixing.

Furthermore, a triangular shape is formed among the supporting plate 5, the beam wall of the cross beam 2, the side wall of the connecting part 3 and the side wall of the upright post 1. Be triangle-shaped between the lateral wall through

backup pad

5, 2 roof beam walls of crossbeam, 3 lateral walls of connecting portion and stand 1 lateral wall, because the fixed mode of triangle-shaped is more stable for other fixed modes, so the joint strength between backup pad 5 ability further strengthening crossbeam 2 and the stand 1.

Further, fixed subassembly 6 is including fixed inserted block 6a and the stopper 6b that can pass fixed part 3b and fixed part two 4b in proper order, and fixed inserted block 6a is including the first fixed segment 6a1 and the second fixed segment 6a2 that all can run through fixed part 3b and fixed part two 4b, and fixed inserted block 6a still includes the linkage segment 6a3 that is connected with first fixed segment 6a1 and second fixed segment 6a2, and stopper 6b can run through the one end that linkage segment 6a3 was all kept away from to first fixed segment 6a1 and second fixed segment 6a 2. Specifically, run through fixed part 3b and two 4b and support to the back until linkage segment 6a3 and fixed part 3b in proper order as fixed inserted block 6a, the fixed part upper end is stretched out with two 6a2 of fixed section this moment fixed section, because one 6a1 of fixed section and two 6a2 of fixed section keep away from linkage segment 6a 3's one end all seted up spacing hole, so run through stopper 6b this moment, can make fixed inserted block 6a form vertical location, thereby make and form transverse orientation between connecting portion 3 and the cooperation portion 4, and all fix with crossbeam 2 mutually with stopper 6b both ends through the fastener, can prevent that stopper 6b from deviating from spacing hole, thereby further strengthened the installation location of fixed subassembly 6, thereby strengthened joint strength and installation stability between stand 1 and crossbeam 2.

Furthermore, a first fixing hole 3b2 through which the first fixing section 6a1 passes and a second fixing hole 3b3 through which the second fixing section 6a2 passes are arranged on the first fixing portion 3b, a third fixing hole 4b2 corresponding to the first fixing hole 3b2 and through which the first fixing section 6a1 passes and a fourth fixing hole 4b3 corresponding to the second fixing hole 3b3 and through which the second fixing section 6a2 passes are arranged on the second fixing portion 4b, the first fixing hole 3b2 and one end of the second fixing hole 3b3 close to the connecting section 6a3 form arc transition, and the connecting section 6a3 forms arc transition between one side, facing the first fixing section 6a1 and the second fixing section 6a2, of the first fixing section 6a1 and the second fixing section 6a2 and the first fixing section 6a1 and the second fixing section. It is excessive to be the circular arc through being between one end that one fixed orifices 3b2 and two fixed orifices 3b3 are close to linkage segment 6a3, can make and play the effect of direction when fixed inserted block 6a inserts one fixed orifices 3b2 and two fixed orifices 3b3, thereby it is more smooth when making fixed inserted block 6a insert, and linkage segment 6a3 is excessive towards being the circular arc between one side of one fixed segment 6a1 and two fixed segments 6a2 and fixed segment 6a1 and the fixed two, can make when fixed inserting fast insert the back completely, can closely laminate with one fixed segment 3b bottom, thereby installation stability and joint strength have been strengthened.
