Problems solved by technology

However, the two semi-annular bodies of this scheme are fixedly connected by tapered pins, and the use of tapered pins to realize the fixed connection of the two semi-annular bodies will inevitably cause free travel between the two semi-annular bodies, that is, Create voids, resulting in weak fixation of concave and convex reinforcement

Embodiment 1

[0028] Such as figure 1 , image 3 , Figure 5 As shown, a concave-convex steel bar joint includes a tubular joint assembly 10 that can be sleeved on the concave-convex steel bar 100. The joint assembly 10 is a detachable structure. When the joint assembly 10 is sleeved on the concave-convex steel bar 100 , the inner wall of the joint assembly 10 fits closely with the concave and convex places on the concave-convex steel bar 100, and also includes a tubular fastener 20 fixedly connected with the joint assembly 10, and the two ends of the fastener 20 are respectively A joint assembly 10 is detachably connected. The outer wall of the joint assembly 10 has an external thread, and the fastener 20 may be in the shape of a sleeve with an internal thread, that is, the inner wall of the fastener 20 has an internal thread that is compatible with the external thread on the external wall of the joint assembly 10, and the joint assembly 10 and The fastener 20 is screwed and fixed. Tha...

Embodiment 2

[0036] The structure and working principle of this embodiment are basically the same as that of Embodiment 1, the difference is that, as figure 2 , Figure 4 As shown, the joint assembly 10 includes two joint sleeves 11, and the two joint sleeves 11 are rotationally connected through the lock shaft assembly 101, that is to say, the two joint sleeves 11 are connected together through the lock shaft assembly 101, and can be opened or closed. .

[0037] Several reinforcing ribs 21 are provided on the outer wall of the fastener 20 , and the reinforcing ribs 21 are in the shape of a ring, which can strengthen the fastener 20 radially and improve the radial tensile strength of the fastener 20 . At least one reinforcing rib 21 is arranged in the middle of the fastener 20, and an annular expansion hole 22 is provided on the inner wall of the fastener 20 corresponding to the position of the reinforcing rib 21, when the concave-convex reinforcing bar 100 When the joint assembly 10 is...

Abstract

The invention discloses a concave-convex steel bar joint which comprises tubular joint assemblies and tubular fastening pieces, wherein the joint assemblies can be arranged on concave-convex steel bars in a sleeving manner and adopt detachable structures, and when the joint assemblies are arranged on the concave-convex steel bars in a sleeving manner, inner walls of the joint assemblies are tightly attached with concave and convex parts of the concave-convex steel bars; and the fastening pieces are fixedly connected with the joint assemblies, and one joint assembly is detachably connected to each of two ends of each fastening piece. The concave-convex steel bar joint has the advantages that the structure is simple, the manufacture is easy, the concave-convex steel bars are convenient and fast to connect, the connection is firm and the like.

Description

technical field [0001] The invention belongs to the technical field of construction industry and relates to a concave-convex steel bar joint, which is used for connecting two concave-convex steel bars. Background technique [0002] At present, concavo-convex joints have been widely used to connect concavo-convex rebars in concrete engineering at home and abroad. The most commonly used conical concavo-convex rebar joints, pier thick straight concavo-convex rebar joints and rolled straight concavo-convex rebar joints all use single-end concavo-convex joints. , It is time-consuming to make the concavity and convexity of the end of the steel bar or to connect the steel bar with a connecting sleeve on site, and the connection is inconvenient. [0003] In order to overcome the deficiencies of the existing technology, people have put forward various solutions through continuous exploration. For example, a Chinese patent document discloses a concave-convex steel bar joint and its pr...
