Description
Technical field
The present invention relates to fabricated construction technical field, in particular to combination spiral shell is tightened in a kind of outside for assembling structure
Line part.
Technical background
As the upgrading of national economy develops, precast assembly structure has been increasingly becoming the important development strategy of country, special
It is not in big city and megalopolis, the requirement of environment allows precast assembly structure to become the urgent market demand；But current nothing
By being the other structures field such as precast assembly building field or prefabricated bridge and tunnel, the steel as main bearing member
The connection method of muscle still remains many disputes, such as most common grout sleeve connection type, due to its construction requirement is stringent,
It is the disadvantages of lacking effective detection means, in the field of business always by dispute.
Another scheme that the stressed members such as reinforcing bar connect in precast assembly structure is to be bolted, but be bolted not
But it is more significant to the weakening ratio of member section, and tightened due to bolt and need biggish space, in particular for a spanner
The fixed angle of rotation can only connect so that bolt is not used to the reinforcing bar connection of certain depth inside works in structure
The reinforcing bar on object surface layer；In addition, can not use since reinforcing bar connection bolt is generally all parallel with works surface and need front
The equipment such as the pneumatic impact spanner of bolt are directed at, so that the torque value that bolt is tightened is extremely restricted.
To be located at sightless hidden region screw element installation and tighten, have no effective measures at present.
Another important problem of precast assembly structure is the leakproofness of seam, and existing precast assembly technology is more difficult
Guarantee that being fully sealed for seam, especially long term seal are even more to be difficult to ensure.
Summary of the invention
In view of the above-mentioned deficiency of the prior art, the present invention provides a kind of outside for assembling structure and tightens combination screw thread
Part, the first purpose are to realize the rotation of little space and hidden region screw element in fabricated construction and tighten.

It is fixed on the outside of the screw element main part, the flexible tensile part passes through after winding in the screw element main part groove by presetting channel
Hidden region is exported, flexible tensile part winding section is constrained on the outside of the screw element main part by the interim protective cover；?
External any region affects the flexible tensile part, and the interim protective cover is rotated or fallen off, and the flexible tensile part passes through institute
The intermal force for stating flexible tensile part fixing piece rotates the screw element main part, tightens or unclamp screw element main part to realize
Effect.
It include screw element main part end face and outer wall on the outside of the screw element main part.
Preferably, the flexible tensile part uses drag-line, chain, hawser or other threadlike bodies, institute corresponding with the chain
It states and chain colyliform lobe is set on the outside of screw element main part.
Preferably, the flexible tensile part fixing piece use fixing screws, the flexible tensile part fixing piece be one or
It is multiple.
Preferably, the interim protective cover uses C-spring thin slice.
An aperture, the hole shape and the fixing screws phase is arranged in groove ends on the outside of the screw element main part
Matching, the flexible tensile part and the fixing screws anchor connection, it is described soft that the fixing screws are packed into the aperture realization
Property tensile elements fix, torsion needed for the fixing screws transmit screw element main part rotation when the flexible tensile part is drawn
Square.
Further technical solution is that the flexible tensile part is directly bonded with the screw element main part using seccotine.
Further technical solution is that hidden region is drawn at flexible tensile part both ends, in flexible tensile part two
End can affect the screw element main part, realize the Double-directional rotary of the screw element main part.
Further technical solution is that hidden region, the flexible tensile part are drawn in flexible tensile part both ends
It joins end to end annular in shape, any direction affects the flexible tensile part, plays the role of the transmission belt of circulation, realizes the screw thread
The Double-directional rotary and continuous rotation of part main part.
Further technical solution is the upper fixed lobe part that one or more arbitrary shapes are arranged, the spiral shell
Setting and the matched groove of fixed lobe part shape on the flexible tensile part on the outside of line part main part, to increase the flexible tensile
Tractive force between part and the screw element main part.
Further technical solution, which is that the flexible tensile part later period penetrates, to be simply wrapped in outside the screw element main part
The screw element main part is realized by friction between the flexible tensile part and the screw element main part or concave-convex pressure in side
Rotation.
Further technical solution is that the flexible tensile part turns after winding on the outside of the screw element main part
Narrow space or hidden region are drawn along the vertically screw element main part axis direction, realizes the axis direction traction flexible drawing
Power part tightens the effect of the screw element main part.
Further technical solution is that lubrication lantern ring is arranged at extraction channel turning, reduces the flexible tensile part
With the frictional resistance between the reserved channel.
Preferably, the stretching force setting fracture force threshold of the flexible tensile part, the fracture force threshold are tightened with required
Torque is corresponding, and when reaching the screw-down torque, the flexible tensile part fracture, completes to tighten.
The present invention has below beneficial to benefit.
The present invention combines tightening for screw element and only needs little space, not by the limit for the spanner operating space for tightening screw element
System especially solves the problems, such as to tighten in the screw element of invisible area, greatly expands screw element connection and fastening
The scope of application, purposes first is that can it is extremely effective solve the problems, such as that screw thread when assembled architecture steel reinforcement abutting joints is tightened, before
Scape is very wide.
Combination screw element is tightened due to outside of the invention to tighten using the traction of flexible tensile part, it can be achieved that biggish tighten
Torque, when powerful screw-down torque is acted on the connection screw thread part between two components of assembling structure, fabricated construction seam
On will form sufficient compressive pre-stress, so that seam is in permanent preloading condition, to guarantee the leakproofness and waterproofness of seam
Energy.
