Abstract
The utility model discloses a connecting sleeve of straight thread reinforcing steel bars. The connecting sleeve is characterized in that convex ribs are arranged on the outer surface of the sleeve along the longitudinal direction of the sleeve. The connecting sleeve is formed by improving the traditional sleeve and arranging the convex ribs on the outer surface of the sleeve. The convex ribs serve as acting points of tools, so that construction tools do not slip and the working efficiency is improved. Sleeves with different inner diameters, which are matched with the straight thread reinforcing steel bars connected by the sleeves, can be formed according to the model numbers of the straight thread reinforcing steel bars connected by the sleeves. The connecting sleeve is widely used for connecting the straight thread reinforcing steel bars of various model numbers.
Description
Technical field
The utility model relates to a kind of branch sleeve, is specifically related to a kind of branch sleeve that is used for the straight thread reinforcing bar.
Background technology
The straight thread reinforcing bar is widely used in various construction works, and particularly various large-scale, heavy, light thin walls and high building structure mainly bear tensile stress in concrete.Connection between the straight thread reinforcing bar is an essential vital again operation in the work progress.
Connection between the existing straight thread reinforcing bar generally is to adopt sleeve that the end of two straight thread reinforcing bars is coupled together.At present the sleeve that adopts all is hollow circular cylinder basically, and the inner surface of sleeve is provided with internal thread, and the two ends of straight thread reinforcing bar are shaped on corresponding external screw thread, an end of two straight thread reinforcing bars respectively with sleeve by being threaded.The present sleeve that uses, when sleeve being rotationally connected the straight thread reinforcing bar, instrument does not have origin of force, skids easily, has increased the difficulty of construction, has reduced efficiency of construction.In order to address this problem, the manufacturer that has has proposed to be provided with the clamping face that is symmetrical in sleeve axis on the external surface of sleeve, but this scheme in use, still can not form effective origin of force to construction tool, and this clamping face scabbles by the sleeve circular surfaces and forms, and so not only can reduce the intensity of sleeve, when tool using is constructed to power on clamping face, cause the sleeve distortion easily, can not satisfy the requirement of practice of construction.
The utility model content
The utility model is in order to overcome the deficiency that above prior art exists, and a kind of rational in infrastructure, easy for installation, straight thread reinforcing steel bar connecting sleeve tube of increasing work efficiency is provided.
The purpose of this utility model realizes by following technical scheme: a kind of straight thread reinforcing steel bar connecting sleeve tube is characterized in that, along the rib that vertically is provided with protrusion at the external surface of sleeve of described sleeve.
As preferably, at least two on the rib of described protrusion, described rib evenly distributes at the external surface of sleeve.Such rib can be used as the origin of force of construction tool, and construction tool is clamped on the rib, conveniently screws; Rib can play the effect of reinforcing rib simultaneously, helps improving the intensity of sleeve.
The rib of described protrusion is three.Rib was both reasonably distributed like this, again cost of production was not had too big influence.
The two ends of described sleeve outer surface are provided with chamfering.Such structure, at the moving process of constructing after connecting or connecting, the sleeve two ends are not easy to cause constructor's scratch.
The longitudinal cross-section of described rib is a rectangle, and described rectangular long limit is positioned on the external surface of described sleeve.
As preferably, the longitudinal cross-section of described rib is trapezoidal, and described trapezoidal base is positioned on the external surface of described sleeve.Can save certain cost of production like this.
The utility model has following advantage with respect to prior art:
One, this branch sleeve improves existing sleeve, and the rib of protrusion is set on the external surface of sleeve, and as the origin of force of instrument, construction tool can not skid, and has improved operating efficiency;
Two, the two ends of this branch sleeve outer face are provided with chamfering, and when connecting the straight thread reinforcing bar, the two ends of sleeve are not easy to cause constructor's scratch, the use that can also save material simultaneously.
Three, this branch sleeve can be according to the model size of the straight thread reinforcing bar that is connected, and the sleeve of making the different inner diameters size matches, and is widely used in the connection of the straight thread reinforcing bar of various models.
Description of drawings
Fig. 1 is the vertical view of straight thread reinforcing steel bar connecting sleeve tube of the present utility model;
Fig. 2 is the A-A sectional drawing of Fig. 1;
Fig. 3 is the left view of straight thread reinforcing steel bar connecting sleeve tube of the present utility model;
Wherein, 1 is the external surface of straight thread reinforcing steel bar connecting sleeve tube; 2 ribs for the protrusion that is provided with on the external surface; 3 is the chamfering at straight thread reinforcing steel bar connecting sleeve tube two ends; 4 is the internal thread of straight thread reinforced bar jointing sleeve tube inner surface.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The structure of straight thread reinforcing steel bar connecting sleeve tube of the present utility model as shown in Figure 1 to Figure 3, branch sleeve is a hollow circular cylinder, the inner surface of branch sleeve is provided with internal thread 4, the rib 2 that external surface 1 vertical along branch sleeve, branch sleeve is provided with 2, three protrusions of rib of three protrusions circumferentially evenly distributes on the external surface of branch sleeve.Article three, the longitudinal cross-section of the rib 2 of protrusion is trapezoidal, and described trapezoidal long base is positioned on the external surface 1 of sleeve.The two ends of branch sleeve external surface 1 are provided with chamfering 3.
Straight thread reinforcing steel bar connecting sleeve tube of the present utility model is to use like this: the two ends of an end of two straight thread reinforcing bars being inserted branch sleeve respectively, with tool holding rotational sleeve on the rib that protrudes, constantly change the position of clamping, all screw until two ends and enter in the sleeve two straight thread reinforcing bars.
The above-mentioned specific embodiment is a preferred embodiment of the present utility model; can not limit claim of the present utility model; for example the longitudinal cross-section of the rib 2 of Tu Chuing is rectangle or the like; other any change that does not deviate from the technical solution of the utility model and made or other equivalent substitute mode are included within the protection domain of the present utility model.
