Abstract
The invention relates to a connecting device, in particular to a steel bar connecting sleeve. The invention adopts the technical proposal that the steel bar connecting sleeve is composed of two conical sleeves, connecting blocks, a fixing plate and springs. The large-diameter ends of the two conical sleeves are connected and the fixing plate is arranged therebetween. The inner cavities of the two conical sleeves are respectively provided with conical connecting blocks, and the head faces of the connecting blocks are connected with the fixing plate through the springs. The steel bar connecting sleeve has the good effects that the steel bar connecting sleeve is suitable for various screwed steel bars with different specifications and shapes; the steel bar connecting sleeve is simple in structure, low in fabrication cost and convenient in connection and greatly improves work efficiency and reduces construction cost.
Description
One, technical field:
The present invention relates to a kind of linkage, particularly relate to a kind of reinforced bar jointing sleeve.
Two, background technology:
The piling technology of in building trade, using always, generally comprise and make a call to a stake hole, many are inserted in the hole with certain interval by the long reinforcing bar that reinforcing bar constituted that links together, several steps such as cement injection in the stake hole then. because according to different geological conditions, therefore a stake hole that has may be very dark, usually needs many reinforcing bars are contacted one by one to be fixed up to form a continuous long reinforcing bar.
The method that much is used for connecting reinforcement is arranged, and in a kind of method therein, reinforcing bar to be connected is crimped onto together by a curling adapter sleeve.But the shortcoming of this method need to be a coiled up device and to need very big operating space.Link together owing to usually need be in a limited space reinforcing bar be curled each other, therefore the range of application of this method is very limited.Another method is to add screw thread in the end of reinforcing bar, utilize a threaded adapter sleeve that two reinforcing bars are coupled together then, because in order to connect two reinforcing bars, the external threading of having to will be threaded earlier is connected on the reinforcing bar, and then an other reinforcing bar rotated in the cover that into is threaded, therefore very trouble operates.But also need to carry out tapping to end reinforced.The inventor proposed a kind of improving one's methods at this point, all screwed middleware inside and outside this method is utilized one, and this middleware being attached on the every reinforcing bar to be connected. the above-mentioned cover of mentioning that is threaded can entirely be set on the middleware by screw thread, and twist back again, thereby be threaded with second middleware.The shortcoming of this method is, still needs reinforcing bar is carried out tapping, and will cause the raising of cost to the additional processing of reinforcing bar.
Three, summary of the invention:
Purpose of the present invention is exactly the above-mentioned defective that exists at prior art, and a kind of simple in structure, reinforced bar jointing sleeve that efficiency of construction is high is provided.
Its technical scheme is: mainly be made up of two conical sleeves, contiguous block, fixed head and springs, major diameter one end of described two conical sleeves links together, the centre is provided with fixed head, the inner chamber of two conical sleeves is respectively equipped with the contiguous block of cone shape, and the end face of contiguous block is connected with fixed head by spring.
Wherein, the contiguous block of described cone shape is that three parts are formed, and the inner chamber of contiguous block is provided with screw thread, cooperates with the reinforcing bar external surface.
The invention has the beneficial effects as follows: be applicable to the line reinforcing bar of various different sizes, shape, it is simple in structure, and cost of manufacture is lower, and is easy to connect, has improved operating efficiency greatly, has reduced construction cost.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present invention;
Accompanying drawing 2 is lateral views of the present invention.
Five, the specific embodiment:
In conjunction with the accompanying drawings 1 and 2, the invention will be further described:
Its technical scheme is: mainly be made up of two conical sleeves 1, contiguous block 4, fixed head 3 and spring 2, major diameter one end of described two conical sleeves 1 links together, the centre is provided with fixed head 3, the inner chamber of two conical sleeves 1 is respectively equipped with the contiguous block 4 of cone shape, and the end face of contiguous block 4 is connected with fixed head 3 by spring 2.
Wherein, with reference to accompanying drawing 2, the contiguous block 4 of cone shape is combined by three parts, certainly, also can form or the more parts composition for two parts, and the inner chamber of contiguous block is provided with screw thread, cooperates with the external surface of reinforcing bar 5, and reinforcing bar can firmly block after inserting.
Its use principle is, reinforcing bar inserts the contiguous block in two conical sleeves, because the outer wall that a plurality of contiguous blocks are combined is a cone shape, match with the inner chamber of conical sleeve, cause the reinforcing bar that inserts when the outside application of force, draw tighter and tighter, simultaneously because the contiguous block inner chamber is provided with screw thread, can firmly block reinforcing bar, thus two reinforcing bars are firmly fixing.
