Abstract
The utility model discloses a reinforcement threaded connection sleeve. In the prior art, the outer surface of the reinforcement threaded connection sleeve is round, so that the surface is easy to damage during the connection process, and the connection strength is insufficient. Longitudinal ribs are arranged on the outer surface of the reinforcement threaded connection sleeve, and are extended along the axial direction of the main body of the sleeve. Therefore, during the connection of steel bar connectors, the specified maximum rotating torque for the connection can be easily achieved through an ordinary pipe spanner or other tools without slipping, the connection uniformity is ensured, and the connection quality and the connection speed are guaranteed.
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 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 bulk strength on the reinforcing steel bar coagulation.
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 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 branch sleeve, it has a sleeve body, is provided with screw thread in the described sleeve body, it is characterized in that, described sleeve body surface is provided with vertical rib, and rib extends axially along described sleeve body
Preferred as technique scheme, described vertical rib is two or more.
Preferred as technique scheme, described vertical rib cross section is quadrangle or hexagon or octagon.
Preferred as technique scheme, described vertical rib and described sleeve body are one-body molded.
Preferred as technique scheme, described vertical rib is equally spaced in described sleeve body external surface.
The utility model proposes a kind of screw thread steel 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 branch sleeve external surface that the utility model proposes is provided with vertical rib, described vertical rib extending axially along described sleeve body.Like this can be easily during the connecting reinforcement joint reach the maximum that connects defined and screw moment and be unlikely to skid, the uniformity of connection is guaranteed, thereby guaranteed quality of connection and speed with common pipe wrench or other instruments.
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, from 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, as shown in Figure 2, is provided with screw thread at sleeve body 1 inwall.As shown in Figure 1, sleeve body 1 external surface be provided with vertical rib.The quantity of vertical rib can be two or more, and vertical rib is 8 among the embodiment as shown in the figure.The shape of vertical rib can be for multiple, and vertical rib cross section is a quadrangle among the embodiment as shown in Figure 1, also can be hexagon or octagon, and vertical rib and described sleeve body are one-body molded, and vertical rib equidistantly is uniformly distributed in described sleeve body external surface.
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.
