Description

The concrete filled steel tube connector

Technical field:

The utility model relates to encased structures, specifically is a kind of concrete filled steel tube connector.

Background technology:

At present, encased structures is widely applied in highrise building.Usually the connection of encased structures adopts flange connection, welding or sleeve pipe to connect.It is with steel tube component end fixed flange that flange connects, again with the method for attachment of two flange through bolton.Though flange connects easy construction, the interface slit is corroded easily, causes to connect to lose efficacy, and too high to the requirement on machining accuracy of interface unit simultaneously, the cost cost drops into excessive.Welding is to utilize the metallic molecule between the connector at high temperature to interpenetrate and integrated method of attachment.Welding can guarantee the tight connection of steel tube component, but higher to welding environment and operator's technical requirements, and is easy to generate weld defect, can't realize standardized work.It is with the coaxial overlap joint of internal and external casing that sleeve pipe connects, and between internal and external casing, pours into expansive cement and sets up the shearing resistance part, relies on the method for attachment that bonds rubbing action and combine.The sleeve pipe link technique is simple and practical, but node processing have relatively high expectations, the sleeve pipe bond length is big, has promoted steel quantity consumption greatly, also ties up a large amount of axial spaces, is difficult to realize high strength tension and resistance to compression requirement simultaneously.

The utility model content:

The utility model is intended to solve the problem that existing encased structures method of attachment exists; And a kind of concrete filled steel tube node bonding strength that can significantly improve is provided; Guarantee the node connectivity robustness; Strengthen node and connect anti-fatigue performance, can realize the concrete filled steel tube connector that the site operation operation is rapid simultaneously.

The technical scheme that the said problem that solves the utility model adopts is:

A kind of concrete filled steel tube connector comprises cover plate, chuck, sleeve, and said cover plate is a ring bodies that outer rim is rounded, and its top edge is provided with the limited block that five equilibrium is arranged, its lower limb is provided with the cover plate double wedge with the corresponding layout of said limited block; Have and the running-on that is connected the outer diameter of steel pipes equidimension in the middle of the said chuck, this running-on edge is provided with the floor of putting more energy into that five equilibrium is arranged; Have on its base plate of said sleeve and the running-on that is connected the outer diameter of steel pipes equidimension; Its top edge is provided with the sleeve double wedge that five equilibrium is arranged; The position of this sleeve double wedge is corresponding with limited block and cover plate double wedge on the cover plate, and the distance between the upper and lower of limited block on the cover plate and cover plate double wedge and this sleeve double wedge uniform thickness.

Further, its top edge of said cover plate is by quartering fixed limit piece, and its lower limb is by quartering securing cover plate double wedge; Said chuck running-on edge is by being connected the cross guiding shear resisting board position of being welded on the steel pipe inwall, the quartering floor of fixedly putting more energy into; Said sleeve top edge quartering fixed muffle double wedge.

Compared with prior art, the beneficial effect of the utility model is: cover plate, chuck, sleeve can be in advance at plant design and processing and fabricatings according to being connected steel pipe sizes and bonding strength requirement, and the job site is assembled into the concrete filled steel tube connector then.Have construction and installation convenient, connect advantages such as measure safety, integral body are connected firmly, suitable complicated construction environment; Can be used for square steel pipe concrete and concrete filled steel tube construction in the building engineering; Especially connected node has good axially loaded performance, flexural property and anti-fatigue performance; All drawbacks of having avoided flange connection, welding and sleeve pipe to be connected have application space and good practical function widely.

The specific embodiment:

Below in conjunction with embodiment the present invention is detailed.

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the concrete filled steel tube connector is combined by cover plate 1, chuck 2,3 three separating members of sleeve.Cover plate 1 is a ring bodies that outer rim is rounded, and its top edge is by fixing four limited blocks 9 of the quartering, and its lower limb outside is corresponding with four limited block 9 positions by fixing 7, four the cover plate double wedges 7 of four curved cover plate double wedges of the quartering; Have chuck running-on 13 in the middle of the chuck 2; The bore of chuck running-on 13 and the connected external diameter equidimension (square opening) that goes up steel pipe 10 and following steel pipe 5; The position of the cross guiding shear resisting board 4 that welds on steel pipe 5 inwalls, four floors 6 of putting more energy into of quartering welding are pressed in chuck running-on 13 edges; Have on the cover tube end plate 14 and the connected sleeve running-on 15 (square opening) of going up the external diameter equidimension of steel pipe 10 and following steel pipe 5; The sleeve 3 top edge quarterings are fixed four sleeve double wedges 8; Limited block 9 on the position of sleeve double wedge 8 and the cover plate 1 is corresponding with cover plate double wedge 7, and the thickness uniform thickness of the distance between the upper and lower of limited block on the cover plate 19 and cover plate double wedge 7 and sleeve double wedge 8.
