Description
Technical Field
The utility model relates to a steel construction beam column node, concretely relates to card formula full bolted connection steel construction beam column node of inserting.
Background
In the connection of the cold-bending square steel pipe column and the H-shaped section beam, the existing method for connecting the column and the beam mainly comprises field welding, but the reliability of the welding seam quality is influenced by the technical proficiency of a welder and the welding environment, the welding quality is not reliable possibly due to the insufficient experience of the welder, the welding environment in which the welder is arranged can also influence the welding seam quality to a certain extent, in addition, the field welding process is complex, the required time is long, and the construction speed of the whole structure is limited.
At present, the assembly type construction method is always advocated by the nation, and the technical difficulty of the assembly type steel structure building is mainly focused on the beam-column connection node. In steel structure building, beam column connected node has traditionally three kinds of connected form: firstly, the upper flange and the lower flange are connected by full penetration welding seams, and the webs are connected by high-strength bolts, namely, bolted welding and mixed connection; the flange and the web are connected by welding seams, namely, are all welded; and thirdly, the upper flange and the lower flange are connected with the web plate through high-strength bolts, namely, full bolts. For the former two connection modes, the upper and lower flanges of the beam are fully-penetration connected, and the beam needs to be installed and welded in construction, but the welding method can cause quality accidents and fire disasters, and the construction speed is greatly influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a card formula full bolted connection steel construction beam column node of inserting to solve above-mentioned technical problem.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a card formula full bolted connection steel construction beam column node of inserting, includes the square steel tubular column and fixes the girder steel subassembly at square steel tubular column global all around respectively, square steel tubular column all be equipped with a draw-in groove on every face all around, the girder steel subassembly include with the beam-ends board of draw-in groove size looks adaptation and with the perpendicular I shape cross-section roof beam that sets up of beam-ends board.
As a further improvement of the above technical solution:
the square steel pipe column is provided with bolts, the beam end plate is provided with mounting holes matched with the bolts, and the beam end plate is fixedly connected with the square steel pipe column through the bolts.
The draw-in groove is by two be relative setting and the cross section is L type connecting plate and constitutes, and two L type connecting plates are vertical the both sides of fixing in square steel tubular column side respectively.
The supporting strip is fixed at the lower ends of the two L-shaped connecting plates, and the beam end plates arranged in the clamping grooves can be prevented from falling off through the supporting strip.
According to the above technical scheme, card formula full bolted connection steel construction beam column node, simple structure, simple to operate, the speed that can effectual improvement construction to security and reliability obtain promotion by a wide margin. Each H-shaped steel beam assembly can be rapidly clamped into the clamping groove from top to bottom in a hoisting method on site without temporary supporting and fixing, so that the construction speed is effectively improved, and the safety is greatly improved.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1-5, the card-inserted full-bolt connection steel structure beam column node of the present embodiment includes a square steel pipe column 2 and steel beam components respectively fixed on the four circumferential surfaces of the square steel pipe column 2, each of the surfaces around the square steel pipe column 2 is provided with a clamping groove 3, and the clamping grooves 3 and the side surfaces of the square steel pipe column 2 jointly form a U-shaped clamping groove into which a clamping plate can be clamped. The steel beam assembly comprises a beam end plate 4 matched with the clamping groove 3 in size and an I-shaped section beam 1 perpendicular to the beam end plate 4.
The square steel pipe column 2 is provided with bolts 5, the beam end plate 4 is provided with mounting holes 41 matched with the bolts 5, and the beam end plate 4 penetrates through the mounting holes 41 through the bolts 5 to be fixedly connected with the square steel pipe column 2.
The draw-in groove 3 of this embodiment is relative setting and the cross section is L type connecting plate by two and constitutes, and two L type connecting plates are vertical the both sides of fixing in 2 sides of square steel-pipe column respectively. The lower ends of the two L-shaped connecting plates further comprise supporting strips 6 which are arranged in the horizontal direction, the supporting strips 6 are fixed at the lower ends of the two L-shaped connecting plates, and the beam end plates 4 arranged in the clamping grooves 3 can be prevented from falling off through the supporting strips 6.
During installation, firstly, the L-shaped clamping grooves 3 and the lower beam supporting strips 6 are welded on the cold-formed thin-wall square steel pipe column 2, and the beam end plates 4 are welded at the beam ends of the beams 1 with the cross-shaped sections to form the H-shaped steel beam assembly. And then the H-shaped steel beam assembly is clamped into the clamping groove of the cold-bending thin-wall square steel pipe column from top to bottom in a field hoisting mode, and finally the I-shaped beam assembly and the square steel pipe column are bound and connected through forming reliable connection through the pair of elongated bolts 5 to form a reliable beam column node.
The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
