Abstract
The utility model discloses a South Korean standard steel bar connecting sleeve. Grooves are evenly arranged on the external surface of the South Korean standard steel bar connecting sleeve. Threads of different directions are arranged on the inner surfaces of the two ends of the South Korean standard steel bar connecting sleeve. By adopting the structure, the utility model has the advantages that the South Korean standard steel bar connecting sleeve can be closely combined with steel bars and concrete, and the use of users is convenient.
Description
Technical field
The utility model relates to the reinforcing bar connector that uses in a kind of building field, especially relates to a kind of Korea S standard series reinforcing steel bar connecting sleeve tube.
Background technology
In the modern architecture industry, also more and more higher along with constantly increasing of building body construction height to the requirement of the quality of connection of reinforcing bar, directly have influence on the quality of whole engineering.The quality of connection that improves reinforcing bar mainly can improve from stretch-proof between raising reinforcing bar and the branch sleeve and bonding force two aspects between anti-torsional strength and raising branch sleeve and the concrete, but present branch sleeve has been ignored the bonding force aspect that improves between branch sleeve and the concrete, and be in the inner single thread structure that adopts of branch sleeve aspect stretch-proof between raising reinforcing bar and branch sleeve and the anti-torsional strength, can better not improve stretch-proof and anti-torsional strength between reinforcing bar and the branch sleeve.
The utility model content
The purpose of this utility model provides a kind of Korea S standard series reinforcing steel bar connecting sleeve tube, can combine with reinforcing bar, concrete closely, and is user-friendly.
For achieving the above object, the utility model provides a kind of Korea S standard series reinforcing steel bar connecting sleeve tube, the external surface of described Korea S standard series reinforcing steel bar connecting sleeve tube evenly is provided with groove, and the inner surface at described Korea S standard series reinforcing steel bar connecting sleeve tube two ends is provided with the screw thread of different directions.
The hand of spiral that the inner surface at described Korea S standard series reinforcing steel bar connecting sleeve tube two ends is provided with differs 180 degree.
Therefore, the utility model uses Korea S's standard series reinforcing steel bar connecting sleeve tube of said structure, can combine with reinforcing bar, concrete closely, and is user-friendly.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the utility model Korea S standard series reinforcing steel bar connecting sleeve tube;
Fig. 2 is that the A-A of embodiment of the utility model Korea S standard series reinforcing steel bar connecting sleeve tube is to the cross section structure schematic diagram.
The specific embodiment
Embodiment
Fig. 1 is the structural representation of the embodiment of the utility model Korea S standard series reinforcing steel bar connecting sleeve tube, as shown in Figure 1, the external surface of described Korea S standard series reinforcing steel bar connecting sleeve tube evenly is provided with groove 1, Fig. 2 is that the A-A of embodiment of the utility model Korea S standard series reinforcing steel bar connecting sleeve tube is to the cross section structure schematic diagram, at the external surface of Korea S's standard series reinforcing steel bar connecting sleeve tube groove being set and can improving bonding force between branch sleeve and the concrete. the inner surface at described Korea S standard series reinforcing steel bar connecting sleeve tube two ends is provided with the screw thread 2 of different directions, the hand of spiral that the inner surface at the standard series reinforcing steel bar connecting sleeve tube two ends of Korea S described in the present embodiment is provided with differs 180 degree, be provided with in the same way screw thread with the inner surface at two ends and compare, can better improve stretch-proof and anti-torsional strength between reinforcing bar and the branch sleeve.
Therefore, the utility model uses Korea S's standard series reinforcing steel bar connecting sleeve tube of said structure, can combine with reinforcing bar, concrete closely, and is user-friendly.
It should be noted that at last: above embodiment is only in order to explanation the technical solution of the utility model but not limit it, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that: it still can make amendment or be equal to replacement the technical solution of the utility model, and these modifications or be equal to replacement and also can not make amended technical scheme break away from the spirit and scope of technical solutions of the utility model.
