Abstract
The utility model provides a kind of solderable steel bar mechanical connection sleeve, it includes construction module steel plate, sleeve is welded on the construction module steel plate, one end outer rim of the sleeve being in contact with construction module steel plate is machined with welding groove, and the welding groove is welded and fixed by solder joint and construction module steel plate；It is threaded hole on the top of sleeve, passes through screw thread on the threaded hole and the threaded post of steel bar end is in mating connection.Sleeve is connected by using this, the design of CAP1000/1400 nuclear island is can satisfy to the design requirement of steel concrete supporting sleeve performance, does not influence the switching performance of sleeve and reinforcing bar.
Description
Technical field
The utility model relates to building iron connection mounting technique field more particularly to a kind of solderable steel bar mechanical connections
Sleeve.
Background technique
It is cylindrical body steel member that conventional rebar, which is mechanically connected sleeve, hollow, interior threaded to connect threaded silk head
Reinforcing bar, related request meet JGJ 107《Mechanical connection technique of reinforcement regulation》, on the market using relatively wide.
In the design of some special engineerings, such as CAP1000/1400 nuclear island engineering, mechanical sleeves one end and structural steel are needed
Plate welding, the other end reconnect the reinforcing bar with silk head.In such cases, if using conventional reinforcing steel bar machinery sleeve, sleeve with
Steel plate welding before need finished edge, since sleeve is hollow, wall thickness is relatively thin, groove is unable to reach given dimensional, it is difficult to meet its by
Force request.
Therefore, it is necessary to design one kind to be welded on structural steel and iron, the solderable steel bar machine of reinforcing bar is then reconnected
Tool connects sleeve.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of solderable steel bars to be mechanically connected sleeve, by using
This connection sleeve, can satisfy the design of CAP1000/1400 nuclear island to the design requirement of steel concrete supporting sleeve performance, not shadow
Ring the switching performance of sleeve and reinforcing bar.
In order to realize above-mentioned technical characteristic, what the purpose of this utility model was realized in：A kind of solderable steel bar machine
Tool connects sleeve, it includes construction module steel plate, is welded with sleeve on the construction module steel plate, the sleeve with knot
One end outer rim that structure module steel plate is in contact is machined with welding groove, and the welding groove is welded by solder joint and construction module steel plate
Connect fixation；It is threaded hole on the top of sleeve, is matched by screw thread with the threaded post of steel bar end on the threaded hole
Connection.
The outer cover of the sleeve is equipped with reinforced seat, is bolted phase between the reinforced seat and construction module steel plate
Even.
The through-hole matched with sleeve is machined on the reinforced seat.
The aperture of the threaded hole is 18mm ~ 50mm.
The utility model has the advantages that：
1, it by using above-mentioned connection sleeve, can satisfy being connected and fixed between reinforcing bar and construction module steel plate, lead to
It crosses one end in sleeve and is machined with groove, and then ensure that its welded connecting intensity between construction module steel plate, and not
The normal use that will affect sleeve avoids the deformation of its recurring structure.
2, sleeve can further be fixed by the outer cover in sleeve equipped with reinforced seat, and then ensure that its structure
Stability connect it with construction module steel plate more stable.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 the utility model overall structure diagram.
In figure：Construction module steel plate 1, bolt 2, reinforced seat 3, solder joint 4, sleeve 5, threaded hole 6, threaded post 7, reinforcing bar 8.
Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
Referring to Fig. 1, a kind of solderable steel bar mechanical connection sleeve, it includes construction module steel plate 1, the construction module steel
Sleeve 5 is welded on plate 1, one end outer rim of the sleeve 5 being in contact with construction module steel plate 1 is machined with welding slope
Mouthful, the welding groove is welded and fixed by solder joint 4 with construction module steel plate 1；Hole 6, institute are threaded on the top of sleeve 5
It states in mating connection by screw thread and the threaded post 7 of 8 end of reinforcing bar on threaded hole 6.It, can by using above-mentioned connection sleeve
For the connection between reinforcing bar 8 and construction module steel plate 1, during Specific construction, firstly, the finished edge on sleeve 5, so
End where groove and the end face of construction module steel plate 1 are welded afterwards, after being welded and fixed, reinforced seat 3 is sleeved on the outer of sleeve 5
Portion, and be fixed on construction module steel plate 1 by bolt 2, finally reinforcing bar 8 is fixedly connected on inside threaded hole 6, is realized
Fixation between reinforcing bar 8 and sleeve 5.
Further, the outer cover of the sleeve 5 is equipped with reinforced seat 3, between the reinforced seat 3 and construction module steel plate 1
It is fixedly linked by bolt 2.It can be further fixed to sleeve 5 by the reinforced seat 3
Further, the through-hole matched with sleeve 5 is machined on the reinforced seat 3.Guarantee that sleeve 5 can by through-hole
Smoothly pass through.
Further, the aperture of the threaded hole 6 is 18mm ~ 50mm.It can adapt to different-diameter by different size
Reinforcing bar.
The working process and principle of the utility model are：
In the design of some special engineerings, if construction module makes outside the venue in CP1000/1400 nuclear island engineering, then field
Interior installation carries out the connection of reinforcing bar again after installation is complete, at this time if not having to solderable jacket cylinder inside directly by reinforcing bar
It being welded to connect with steel plate, site workload is big, and most of region is limited by space, can not be welded, not can guarantee welding quality,
It is therefore desirable to use solderable jacket cylinder, which completes to be welded to connect in over-the-counter workshop with module, then on the scene
Internal screw thread connects reinforcing bar.
This sleeve is according to JGJ 107《Mechanical connection technique of reinforcement regulation》It designs with CAP1000/1400 nuclear island to reinforcing bar machine
Tool connects the design requirement of sleeve, includes welding requirements AWS D1.4 and mechanical test requirement：Static(al) tensioning strength test,
Tensile compression test, autonomous Design go out satisfaction and want repeatedly for tensile compression test, large deformation repeatedly for cyclic loading test, strain-gauge test, high stress
The solderable steel bar mechanical connection sleeve asked, is suitable for bar gauge 18mm ~ 50mm diameter.
Sleeve 5 and construction module steel plate 1 are welded in workshop, then transport construction module steel plate 1 to engineering site,
After the completion of it is lifted, by the threaded hole 6 of sleeve 5 and 7 mechanical snap of threaded post of reinforcing bar 8 to connect reinforcing bar.
The above embodiments are only the optimal technical scheme of the utility model, and are not construed as the limit for the utility model
System, the technical solution that the protection scope of the utility model should be recorded with claim, the technical solution recorded including claim
The equivalents of middle technical characteristic are protection scope.Equivalent replacement i.e. within this range is improved, also in the utility model
Protection scope within.
