[0002] With the advancement of science and technology, many construction fields use prefabricated construction methods. Prefabricated parts are mass-produced by factories and transported to construction sites for assembly. When performing prefabricated installation, steel sleeves are used to connect steel bars. Steel sleeves are divided into cold extrusion type and threaded connection. When threaded steel bars are used, the ends of the steel bars are processed into straight threads by rolling process, and the two steel bars are connected and fixed to each other with corresponding connecting sleeves. In order to facilitate convenience in actual operation, the prior art has made many improvements to the connection of steel sleeves, but there are still certain obstacles to the convenience of sleeve installation. Therefore, there is a need in the art to improve the prefabricated steel sleeves to solve the defects of the prior art. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a novel assembled mortise and tenon-laryngeal clamp connection sleeve, which utilizes the simple and quick connection characteristics of the mortise and tenon and the throat clamp of the product to improve the efficiency in actual operation.

[0004] A novel assembled mortise and tenon-throat clamp connection sleeve comprises a first mortise and tenon connection sleeve 1, a second mortise and tenon connection sleeve 2, and a throat clamp 3. The first mortise and tenon connection sleeve 1 and the second mortise and tenon connection sleeve 2 are provided with a tenon and a mortise groove at one end, and after the other end is connected to the facing ends of the first straight threaded steel bar 4 and the second straight threaded steel bar 5, a tight connection is achieved by splicing the concave and convex mortise and tenon on the first mortise and tenon connection sleeve 1 and the second mortise and tenon connection sleeve 2, ensuring that they are integrated along the longitudinal direction of the steel bar. The throat clamp 3 is tightened at the mortise and tenon intersection of the first mortise and tenon connection sleeve 1 and the second mortise and tenon connection sleeve 2 by screws, limiting the relative radial displacement of the first mortise and tenon connection sleeve 1 and the second mortise and tenon connection sleeve 2, thereby ensuring that the two steel bars are connected as a whole.

[0005] As a further improvement of the present invention, the first mortise and tenon type connection sleeve 1 and the second mortise and tenon type connection sleeve 2 have the same diameter, the same mortise and tenon end structure, and the same diameter of the connected threaded steel bars.

[0006] As a further improvement of the present invention, the length of the tenon portion (protruding portion) at the end of the first mortise and tenon type connecting sleeve 1 along the transverse direction of the sleeve is 3 / 4 of the diameter of the sleeve.

[0007] As a further improvement of the present invention, the length of the middle tenon groove portion (recessed portion) of the first mortise and tenon type connecting sleeve 1 along the lateral direction of the sleeve is 1 / 4 of the sleeve diameter.

[0008] As a further improvement of the present invention, the tenon portion and the tenon groove portion of the first mortise and tenon type connecting sleeve 1 are equal in length along the longitudinal direction of the sleeve.

[0009] As a further improvement of the present invention, three throat hoops 3 are arranged, and the hoops are evenly distributed at the mortise and tenon joints between the first mortise and tenon type connection sleeve 1 and the second mortise and tenon type connection sleeve 2.

[0010] Compared with the prior art, the invention has the following beneficial effects: the two mortise and tenon type connection sleeves and the throat hoop in the invention ensure the connection strength between the steel bar components, and utilize the simplicity and convenience of the mortise and tenon and throat hoop splicing connection to improve the efficiency of actual operation and installation. The throat hoop has a balanced torsional moment, is firmly and tightly locked, and only requires an electric screwdriver for the tightening operation, which shortens the installation time, speeds up the construction progress, and reduces the engineering cost.
