Abstract
The utility model discloses a sliding connection between steel member and concrete comprises the connecting piece body, the connecting piece body is including fixing the anchor assembly in the concrete main part, be provided with at least one bar hole on anchor assembly's the base, every the bar is downthehole be provided with the bolt fixed on the steel member and with the supporting nut of bolt, every be provided with the protection casing on the bar hole, the lower part of protection casing be provided with with the bar hole is corresponding and hold the nut with the bolt is followed the gliding plenum chamber in bar hole. The utility model discloses do not take place between steel member and the concrete under relative separation's the condition can guaranteeing, allow to take place certain relative slip between steel member and the concrete, avoid being drawn the concrete cracking's that causes problem because of concrete member.
Description
Technical field
The utility model is related to architectural engineering, the sliding connector between more particularly to a kind of steel member and concrete.
Background technology
In combining structure, the connection between steel member and concrete is typically connected using peg, and existing connector leads to
The Relative sliding crossed between limitation steel member and concrete is to ensure cooperation.But for some positions or some regions, but
Need steel member and concrete component that unidirectional slip is produced under the premise of indissociable.Such as Prestressed Steel and Concrete Composite Beam
Or continuous composite slabs, institute's bending moment is mainly hogging moment near intermediate support, and existing connector can be limited in hogging moment area
Steel member and the Relative sliding of concrete, produce tension in concrete, even result in concrete cracking.Therefore, ensureing
Under conditions of concrete is not separated from each other with steel member, some directions between hogging moment area inner concrete and steel member are reduced
Compound action, be the key for avoiding the concrete cracking in hogging moment area.Also a kind of resistance to plucking not shear connector due to adopting
With the mode of the arrangement foamed plastics on sliding stroke, realize sliding by the compression of foamed plastics, this mode is present
Following defect：During casting concrete, concrete makes foamed plastics generate initially the lateral pressure of foamed plastics
Compression or destruction, concrete simultaneously occupy sliding channel, and from reducing the sliding ability and functional reliability of connector.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, there is provided the cunning between a kind of steel member and concrete
Follower link, this connector is under conditions of it ensure that and relative separation does not occur between steel member and concrete, it is allowed to steel structure
There is certain relative slip between part and concrete.
The technical scheme that the utility model is used is：Sliding connector between a kind of steel member and concrete, by even
Fitting body is constituted, and the connector body includes the anchoring piece being fixed in concrete main body, on the base of the anchoring piece
At least one bar hole is provided with, the bolt that is fixed on steel member is provided with each described bar hole and is matched somebody with somebody with the bolt
The nut of set, is provided with protective cover on each described bar hole, the bottom of the protective cover is provided with relative with the bar hole
Answer and accommodate the plenum chamber that the nut and the bolt are slided along the bar hole.
Nut stop collar is provided with the bolt in each described bar hole.
The anchoring piece is I-shaped structure, and the both sides of its base are respectively provided with least one bar hole.
The protective cover is made of plastic foam material.
The outer surface of the protective cover is provided with containment vessel.
The beneficial effects of the utility model are：
1st, the utility model sets bar hole on the base of anchoring piece, and welding or other manner are fixed on steel member
Bolt is connected with each other through bar hole with anchoring piece, and the guarantor being made up of plastic foam material is disposed with above bolt head and bar hole
Shield is cast in concrete main body with the protecting crust for being set in protection cover outer surface, anchoring piece, is to realize by above measure
Under conditions of avoiding not separated between steel member and concrete main body, it is allowed to occur between steel member and concrete single
To slip, it is to avoid the problem of the concrete cracking caused by concrete component tension；
2nd, the utility model is disposed with nut stop collar on bolt, it is to avoid caused by nut tension lose slip work(
The problem of energy, it also avoid the problem that steel member is separated from each other with concrete caused by nut excessively pine；
3rd, the connector of existing same type is compared, and the utility model is because foamed plastics is only as encapsulant, and surface
It is disposed with containment vessel, it is to avoid plastic foamboard is damaged and deformation is asked caused by the pressure in concreting process and vibrations
Topic；
4th, the features such as the utility model has simple and compact for structure, with low cost, easy construction, reliable operation.

Specific embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
As shown in Figures 1 and 2, the sliding connector between a kind of steel member and concrete, including it is fixed on concrete
Anchoring piece 1 in main body 10, is provided with least one bar hole 2, in the present embodiment, the anchor on the base of the anchoring piece 1
Firmware 1 is I-shaped structure, and the both sides of its base are respectively provided with a bar hole 2.It is provided with each described bar hole 2
Bolt 4 and the nut 5 supporting with the bolt 4 on steel member 3, each described bolt are fixed on by welding or other manner
Nut stop collar 8 is provided with 4, it is to avoid lose the function that is slidably connected because nut 5 is tightly against pressed on the base of anchoring piece 1
Problem, while nut 5 can be tightened against on nut stop collar 8, it is to avoid nut 5 loosens and causes steel member 3 mutually to divide with concrete
From problem.The protective cover 6 being made up of plastic foam material, the bottom of the protective cover 6 are provided with each described bar hole 2
It is provided with corresponding with the bar hole 2 and accommodates the plenum chamber that the nut 5 and the bolt 4 are slided along the bar hole 2
7；The outer surface of the protective cover 6 is additionally provided with containment vessel 9, it is to avoid caused during casting concrete by foamed plastics material
The protective cover 6 that material is made damages the generation of problem on deformation.
As shown in figure 3, the utility model is used in after construction, the anchoring piece 1 is cast in concrete main body 10,
Bottom is connected by bolt 4 and nut 5 with steel member 3, and anchoring piece 1 can be sent out along the direction of bar hole 2 close to steel member 3
The a range of slip of life, but can not be slided perpendicular to the direction of bar hole 2, can not be separated with steel member 3,
It is achieved in that being unidirectionally slidably connected between steel member 3 and concrete main body 10.
