Description

Construction steel bar connecting piece

Technical Field

The utility model relates to a steel bar connection spare, especially a construction steel bar connection spare.

Background

The mode that generally adopts the steel reinforcement sleeve when construction is connected two reinforcing bars at present stage is fixed, and the screw thread processing is carried out according to the standard in advance to the reinforcing bar tip, then carries out the spiro union with two bar connection end through the steel reinforcement sleeve at the reinforcement in-process and fixes.

However, the position of the two steel bars is strictly required when the traditional steel bar sleeve is installed, the connecting ends of the two steel bars to be connected need to be right, namely, the connecting ends are on the same straight line, small-angle deviation exists easily when the steel bars are placed in actual construction, great trouble can be brought to installation of workers by adopting the traditional steel bar sleeve, and the end of the traditional steel bar sleeve is matched with the steel bar sleeve in the forward direction because the steel bars are difficult to move. Therefore, there is a need to develop a steel bar coupler with more flexible use, which can be conveniently connected and fixed by field workers even if the two steel bar coupling ends are not right opposite and have small angle deviation.

Disclosure of Invention

An object of the utility model is to provide a construction steel bar connection spare, it also can effectively connect even there is the small-angle deviation at two bar connection end, the on-the-spot workman's of being convenient for operation more.

In order to achieve the above purpose, the utility model adopts the following technical proposal: the utility model provides a construction steel bar connection spare, includes to silk, two pressure springs, two ball covers and two sleeves, to the integrative partition baffle that is fixed with of the inside intermediate position of silk, two pressure springs are coaxial to be fixed in separate the baffle both sides, two sleeve inner wall one end systems have the screw thread and respectively with to silk both ends spiro union cooperation, two ball cover appearances are globular and link up and are equipped with the reinforcing bar connecting screw hole, and two ball covers are placed respectively in two sleeves, and two sleeve inner wall other end systems are deviate from by the sleeve other end for the sphere restriction ball cover with ball cover complex, and ball cover and telescopic the terminal surface of the protrusion sleeve other end when the sphere pastes and leans on.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses earlier carry out the spiro union through ball cover and reinforcing bar and fix, compare the effective length in can more audio-visual observation reinforcing bar spiro union entering ball cover with traditional steel sleeve, and sleeve and ball cover sphere contact, the ball cover can carry out the deflection of small-angle, even make two bar linkage end also can carry out effective connection when having the small-angle deviation, fix two sleeves through to the silk at last, the pressure spring pressurized supports and prevents the opposite displacement on the reinforcing bar terminal surface, and is rational in infrastructure effective, the on-the-spot workman's of being convenient for operation more.

Detailed Description

The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.

The first concrete implementation mode is as shown in fig. 1 ~ fig. 2, the utility model discloses a construction steel bar connection spare, including to silk 1, two pressure springs 2, two ball covers 3 and two sleeves 4, to silk 1 inside intermediate position an organic whole be fixed with separate baffle 1-1, two pressure springs 2 coaxial fixings are in separate baffle 1-1 both sides, two sleeve 4 inner wall one end system have the screw thread and respectively with to silk 1 both ends spiro union cooperation, two ball covers 3 appearances are for globular and link up and be equipped with reinforcing bar connection screw hole 3-1, two ball covers 3 are placed respectively in two sleeves 4, two sleeve 4 inner wall other ends system be with ball cover 3 complex sphere restriction ball cover 3 deviate from by the sleeve 4 other end, and ball cover 3 and sleeve 4 the sphere lean on the terminal surface of the sleeve 4 other end when leaning on.

Second embodiment, as shown in fig. 1 ~ and fig. 2, the present embodiment is further described with respect to the first embodiment, in which the diameter of the compression spring 2 is smaller than the inner diameter of the steel bar connection threaded hole 3-1, and the compression spring 2 extends into the steel bar connection threaded hole 3-1 in a free state, so that the compression spring 2 can be pressed and supported on the end surface of the steel bar 5 after the steel bar 5 is screwed and fixed with the steel bar connection threaded hole 3-1.

Third embodiment as shown in fig. 1 ~ and fig. 2, this embodiment is further described with respect to the first embodiment, the surface of the ball sleeve 3 is in clearance fit with the inner wall of the sleeve 4, and the ball sleeve 3 can be pulled out from the end of the sleeve 4 with the thread.

The fourth concrete implementation mode: as shown in fig. 2, the present embodiment is further described with respect to the first embodiment, and the pair of wires 1 and the two sleeves 4 are provided with at least one flat surface 6 on the outer surface thereof for facilitating the locking of the wrench during operation.

Fifth embodiment as shown in fig. 1 ~ and fig. 2, this embodiment is further described with respect to the first embodiment, in which the threads on one end of the inner wall of the two sleeves 4 are reversed, and when the two sleeves 4 are restricted from rotating, the two sleeves 4 can be moved toward or away from each other by rotating the wire pair 1 alone.
