Abstract
The utility model relates to a reinforced bar connecting sleeve, which is mainly used to connect reinforced bars in the building projects and belongs to reinforced bar connecting sleeves which are used in the building projects. The reinforced bar connecting sleeve is characterized in that a tubular metal body excircle is provided with a spiral slot. The utility model has the beneficial effects that the bonding performance between the reinforced bar connecting sleeve and concrete is improved, and the material fatigue strength is improved, which is beneficial for improving the quality of the building projects.
Description
(1) technical field:
The utility model is a kind of reinforcing steel bar connecting sleeve tube, and the reinforcing bar that is mainly used in the construction project connects.It belongs to the reinforcing steel bar connecting sleeve tube of using in the construction project.
(2) background technology:
Employed reinforcing steel bar connecting sleeve tube is to be made of the screw thread in tubular metal body and the tubular metal body mesopore in the existing construction project, and the external circle of its tubular metal is smooth.Because the external circle of its tubular metal is smooth, certainly will reduce reinforcing steel bar connecting sleeve tube in construction project with concrete bond stress, cause the functional performance of reinforcing steel bar connecting sleeve tube to reduce greatly.
(3) summary of the invention:
The purpose of this utility model mainly adopts and has spiral fluted reinforcing steel bar connecting sleeve tube design on the external circle of a kind of tubular metal, solve reinforcing steel bar connecting sleeve tube in construction project with concrete bond stress decline problem, improve the functional performance of reinforcing steel bar connecting sleeve tube.
The design scheme of a kind of reinforcing steel bar connecting sleeve tube described in the utility model is: it is made of the screw thread in the helicla flute on the external circle of tubular metal, tubular metal body and the tubular metal body mesopore.Be characterized in: have helicla flute on the external circle of its tubular metal, the helicla flute bottom land on the external circle of tubular metal is a circular arc.
Originally make real novel described a kind of reinforcing steel bar connecting sleeve tube compared with prior art, its useful contribution is: owing to have helicla flute on its external circle of tubular metal, improved its in construction project with concrete bonding property, fatigue of materials intensity is improved, help improving the construction project quality.
(4) description of drawings:
Fig. 1 is the utility model schematic diagram.
(5) specific embodiment:
1 pair of a kind of reinforcing steel bar connecting sleeve tube of the present utility model is further described as follows in conjunction with the accompanying drawings: a kind of reinforcing steel bar connecting sleeve tube described in the utility model is to be made of the screw thread 3 in the helicla flute 1 on the external circle of tubular metal, tubular metal body 2 and the tubular metal body mesopore.
Be characterized in: have helicla flute on the external circle of its tubular metal.
Claims (2)
1, a kind of reinforcing steel bar connecting sleeve tube is to be made of the screw thread in the helicla flute on the external circle of tubular metal, tubular metal body and the tubular metal body mesopore.It is characterized by: have helicla flute on the external circle of its tubular metal.
2, according to the described a kind of reinforcing steel bar connecting sleeve tube of claim 1, it is characterized by: the helicla flute bottom land that has on its hollow metallic body cylindrical is a circular arc.
