specific Embodiment approach 1

[0005] Specific implementation mode one: the following combination figure 1 with figure 2 This embodiment will be specifically described. It consists of a jacket 1, a left tile 2 and a right tile 3. The tile-shaped left tile 2 and right tile 3 are buckled to form an outer cone sleeve and inserted into the cone hole 1-1 of the jacket 1. The left tile 2 and the right tile Groove 4 is opened on the surface of the inner hole of 3 . The groove 4 is a pit formed by stamping according to the position of the convex ribs distributed on the outer surface of the corresponding type of rebar. The wedge angle α of the jacket 1, the left tile 2 and the right tile 3 is 2-7 degrees. The wedge angle of 2 to 7 degrees is smaller than the friction angle of the material, which can play a good role in preventing loosening.

specific Embodiment approach 2

[0006] Specific implementation mode two: the following combination figure 2 This embodiment will be specifically described. The difference between this embodiment and the first embodiment is that the outer taper sleeve formed by the left tile 2 and the right tile 3 has a seam 5 and a seam 6 at the two junctions. The seam is set so that the two longitudinal convex grooves on the surface of the ordinary rebar can not affect the fastening of the left and right tiles on the surface of the rebar, and this embodiment can also adapt to the error of the outer diameter of the rebar to a certain extent.

specific Embodiment approach 3

[0007] Specific implementation mode three: the following combination figure 1 This embodiment will be specifically described. The difference between this embodiment and the first embodiment is that the middle of the inner surface of the left tile 2 and the right tile 3 has an annular groove 7 along the circumferential direction, and the wedge angle α of the outer casing 1, the left tile 2 and the right tile 3 is preferably is 3 degrees. After the ring groove 7 is provided, defects such as "flash" at the end of the threaded steel will not affect the use of this embodiment.

Abstract

The present invention relates to double tile reinforcing bar connecting sleeve and relates to the connection of building reinforcing bar. The connecting sleeve includes outer sleeve, right tile and left tile. The right tile and the left tile are combined into one inner sleeve with conic surface to be inserted into the outer sleeve and have grooves on the inside surface. When the connecting sleeve is used, the right tile and the left tile are made to surround the ends of butt connected reinforcing bars, their grooves on the inside surface are made to match the ribs no the surface of the reinforcing bars, and outer sleeve is hammered to jacket and lock the tiles. The present invention has less parts, simple machining, low cost and easy in-situ installation.

Description

Technical field: [0001] The invention relates to a connecting sleeve of threaded steel for construction. Background technique: [0002] At present, at the construction site of a building, when the threaded steel to be poured into the cement needs to be butted, welding, tying, cold extrusion and other methods are generally used. The process is cumbersome, and some require special equipment. Although some threaded sleeves also appear now to connect the ends of two rebars with the sleeves, the processing and operation of the sleeves are also complicated. Invention content: [0003] In order to overcome the relatively complex defect of the existing threaded steel joint, a threaded steel connecting sleeve with simple structure and low manufacturing cost is provided. The present invention is achieved through the following scheme: a double-tile threaded steel connecting sleeve, which is composed of an outer sleeve 1, a left tile 2 and a right tile 3, and the tile-shaped left til...
