Reinforcing bar connector
Technical field
The present invention relates to building field, specifically, relate to a kind of reinforcing bar connector.
Background technology
Along with expanding economy, building trade also develops rapidly thereupon.Reinforcing bar has obtained using widely as main body supporting structure in construction work.Mainly be in actual applications be placed on reinforcing bar the form with reinforcing cage of tying up in the hole or the concrete position of precoating on.According to condition of construction sometimes needs reinforcing bar is coupled together, increase the length of reinforcing bar.
The method that reinforcing bar connects has a lot, and current mechanical connection commonly used is with the end reinforced screw thread that adds, utilizes a tapped cylindrical sleeve that two reinforcing bars are coupled together then.This method is enclosed within sleeve on the reinforcing bar then fully earlier with two end reinforced tapping, and the end is concordant, and another root reinforcing bar that will need then to connect docks, and sleeve is rotated into another root reinforcing bar again.Though this method is simple, meeting exposed portions serve screw thread after reinforcing bar connects, the bearing capacity of reduction reinforcing bar.
Summary of the invention
The objective of the invention is in order to address the above problem, specifically, the purpose of this invention is to provide a kind of simple to operate, the reinforcing bar connector that efficiency of construction is high.
According to the present invention, a kind of reinforcing bar connector is provided, comprising: the first and second convex sleeves, the structure of the described first and second convex sleeves is identical, all have projection and bottom cavity part, the inboard of described projection has screw thread, is used for screwing in the end that the outside has the reinforcing bar of screw thread; The solid steel column of worker's type, be used for connecting the described first convex sleeve and the described second convex sleeve, wherein, two ends of the solid steel column of described worker's type are socketed in respectively in the bottom cavity of the described first convex sleeve and the described second convex sleeve, and the diameter of the mid portion of the solid steel column of described worker's type is identical with the diameter of described reinforcing bar.
Preferably, the length of the described inside thread of the described projection of the described first and second convex sleeves is equal to or greater than the reach of described reinforcing bar.
Preferably, the solid steel column of described worker's type and first, second convex jacket casing link into an integrated entity.
From top description and the practice as can be known, according to the present invention, during by reinforcing bar connector connecting reinforcement of the present invention, the reinforcing bar rotation inserts in first, second convex sleeve, make the reinforcing bar external screw thread all enter in the reinforcing bar connector, can prevent that reinforcing bar from connecting back exposed portions serve screw thread, reduces the supporting capacity of reinforcing bar.Simultaneously when connecting because first, second sleeve can rotate, so when connecting fixing reinforcing bar, rotate first, second convex sleeve, relatively more flexible operation in, and simple and convenient, improved the efficient of constructing greatly.

The specific embodiment
The embodiment of reinforcing bar connector of the present invention is described below with reference to the accompanying drawings.Those of ordinary skill in the art can recognize, under situation without departing from the spirit and scope of the present invention, can revise described embodiment with various mode or its combination.Therefore, accompanying drawing is illustrative with being described in essence, rather than is used for the protection domain of restriction claim.In addition, in this manual, accompanying drawing draws not in scale, and identical Reference numeral is represented identical part.
Fig. 1 is the generalized section that reinforcing bar connector of the present invention is shown; Fig. 2 is the generalized section that the convex sleeve of reinforcing bar connector of the present invention is shown; Fig. 3 is the generalized section that the solid steel column of worker's type of reinforcing bar connector of the present invention is shown.
As shown in Figure 1, the described reinforcing bar connector of one embodiment of the present of invention comprises the first and second convex sleeves 10 and the solid steel column 20 of worker's type.Two ends 21 of the solid steel column 20 of worker's type are socketed in respectively in the bottom cavity 12 of the first and second convex sleeves 10.
With reference to Fig. 2 and Fig. 3, convex sleeve 10 comprises projection 11, bottom cavity 12.The inboard of projection 11 has screw thread 13.The diameter of projection 11 and the equal diameters of reinforcing bar be used for to screw in reinforcing bar, and the length of the screw thread 13 of projection 11 inboards is equal to or greater than the external screw thread of reinforcing bar, make the inside that the external screw thread of reinforcing bar all is screwed into projection 11 when screwing in reinforcing bar.The diameter of bottom cavity 12 is greater than the diameter of projection 11, and convex sleeve 10 openings at two ends diameters are identical.
The solid steel column 20 of worker's type comprises mid portion 22 and two ends 21.The diameter of end 21 equals the diameter of the bottom cavity 12 of convex sleeve 10, and be socketed in the bottom cavity 12 of two convex sleeves 10, because the diameter of bottom cavity 12 greater than the diameter of ledge 11, makes end 21 can slide in bottom cavity 12 and can not come off.The diameter of mid portion 22 is identical with the diameter of reinforcing bar.
Fig. 4 is the generalized section when reinforcing bar connector connecting reinforcement of the present invention is shown.
With reference to Fig. 4, when connecting reinforcement, the screw thread 13 of projection 11 inboards by the first convex sleeve the threaded end horizontal alignment of first reinforcing bar rotate in the outstanding cavity 11, and first reinforcing bar is screwed in the bottom cavity 12, push against the bottom of convex sleeve 10 up to the end 21 of worker's steel column 20, the end of first reinforcing bar pushes against the opposite side of the end 21 of the solid steel column 20 of worker's type simultaneously.Same means screw in second reinforcing bar in the second convex sleeve of reinforcing bar connector, until pushing against, thereby finish the connection of reinforcing bar.
As mentioned above, use the reinforcing bar connector connecting reinforcement, when reinforcing bar is screwed in the convex sleeve 10, because the length of the screw thread 13 of convex sleeve 10 inboards of reinforcing bar connector is equal to or greater than the length of the screw thread of reinforcing bar, make the screw thread of reinforcing bar all to be screwed in the reinforcing bar connector, thereby avoided screw thread steel to be exposed and cause supporting capacity to reduce.Simultaneously two convex sleeves 10 of reinforcing bar connector can rotate, thus when connecting fixing reinforcing bar, rotate first, second convex sleeve, relatively flexibly, and simple and convenient operation in, align easily, thereby improved the efficient of constructing greatly.
Under above-mentioned instruction of the present invention, those skilled in the art can improve reinforcing bar connector provided by the present invention on the basis of above-described embodiment or be out of shape, and these improvement or distortion all drop in protection scope of the present invention.It will be understood by those skilled in the art that above-mentioned specific descriptions just explain purpose of the present invention better, protection scope of the present invention is limited by claim and equivalent thereof.
