Abstract
The utility model provides a steel-screw regular-polygonal connecting sleeve. The external surface of the prior steel-screw connecting sleeve is round, therefore, damage is easily caused to the surface in the process of connection and the connection strength is poor. The utility model has a cross section of regular polygon, thus, compared with the prior steel-screw connecting sleeve, the steel-screw regular-polygonal connecting sleeve can enhance the bondability of a steel joint, thereby improving the strength of reinforced concrete and being capable of improving the connection quality and the connection speed of reinforcing steel bars as well.
Description
Technical field
This utility model relates to a kind of steel concrete that is used for and builds the reinforced bar straight thread connector that two reinforcing bars is linked together by straight thread technology---screw thread steel regular polygon branch sleeve.
Background technology
The connection of reinforced bar straight thread joint of the prior art is circular with the sleeve appearance.In long-term construction practice, because what the connection means adopted is that pipe wrench is rotatably connected, in the interlock of moment values size and connector and spanner, there is destabilizing factor, connection procedure skidded and is connected whether to arrive position influence bigger, the surface damage increasing of connector.After concrete setting, do not have the effect of the concrete bulk strength of reinforcing steel bar.
The utility model content
At defective that exists in the prior art and deficiency, the purpose of this utility model is to propose a kind of screw thread steel regular polygon branch sleeve, the existing circular reinforcing bar of the comparing sleeve that is threaded can increase the bond stress of bar splice, thereby improves strength of reinforced concrete, the quality of connection that can improve reinforcing bar and connection speed.
In order to achieve the above object, the utility model proposes a kind of screw thread steel regular polygon branch sleeve, it has a sleeve body, be provided with screw thread in the described sleeve body, it is characterized in that, described sleeve body cross section is a regular polygon, to form along the axial vertical face of sleeve body on the sleeve body surface.
Preferred as technique scheme, described sleeve body external surface is regular hexagon or octagon or regualr decagon or dodecagon.
The utility model proposes a kind of screw thread steel regular polygon branch sleeve.Existing screw thread steel branch sleeve external surface is circular, therefore in connection procedure easily because of damage is caused on the surface, and bonding strength deficiency.The screw thread steel regular polygon branch sleeve cross section that the utility model proposes is a regular polygon, the existing screw thread steel branch sleeve of comparing like this can add the bond stress of bar splice, thereby improves strength of reinforced concrete, the quality of connection that can improve reinforcing bar and connection speed.
Description of drawings
Fig. 1 is the cross-sectional schematic of the utility model preferred embodiment;
Fig. 2 is the lateral view sectional view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.For the person of ordinary skill in the field, to the detailed description of the present utility model, above-mentioned and other purposes of the present utility model, feature and advantage will be apparent.
The utility model preferred embodiment comprises sleeve body 1 as depicted in figs. 1 and 2, is provided with screw thread at sleeve body 1 inwall.As shown in Figure 1, the cross section of sleeve body 1 is a regular polygon, to form on sleeve body 1 surface along the axial vertical face of sleeve body 1.In this preferred embodiment, the cross section of sleeve body 1 is an octagon, thereby has formed eight vertical faces on sleeve body 1 surface.Certainly those skilled in that art are appreciated that; screw thread steel regular polygon branch sleeve of the present utility model is not limited in octagon; this just illustrates; those skilled in that art are appreciated that any regular polygon can realize goal of the invention of the present utility model, and within protection domain of the present utility model.
Though; the utility model clearly demonstrates by above embodiment and accompanying drawing thereof; yet under the situation that does not deviate from the utility model spirit and essence thereof; the person of ordinary skill in the field works as can make various corresponding variations and correction according to the utility model, but these corresponding variations and correction all should belong to the protection domain of claim of the present utility model.
