Abstract
The utility model relates to a rolling straight thread sleeve with ribs, which comprises a connecting sleeve. The utility model is characterized in that the outer wall of the sleeve is provided with two to six longitudinal ribs along an axial direction. Because of the structure, positive effects generated by the utility model are obvious, namely, when steel bar joints are particularly connected, a common pipe wrench or other tools can be easily used for achieving the maximal engagement force moment defined by connection, without slippage, which enables connecting consistency to be ensured to ensure connecting quality and speed.
Description
Technical field
The utility model relates to and is used for the reinforced bar straight thread connector that steel bar concrete casting links together two reinforcing bars by straight thread technology---rolling straight thread ribbed sleeve.
Technical background
The connection of reinforced bar straight thread joint of the prior art sleeve appearance apleuria and smooth, in long-term construction practice, because the time pipe wrench that the connection means adopt is rotatably connected, in the interlock of moment values size and connector and spanner, there is destabilizing factor, connection procedure is skidded and is connected whether to arrive position influence bigger, the surface damage of connector is strengthened.After concrete setting, do not have the effect of the concrete bulk strength of reinforcing steel bar.
Summary of the invention
The purpose of this utility model provides a kind of bond stress that can increase bar splice, thereby improves the rolling straight thread ribbed sleeve of strength of reinforced concrete, the quality of connection that can improve reinforcing bar and connection speed.
The technical solution adopted in the utility model is such, and promptly a kind of rolling straight thread ribbed sleeve comprises branch sleeve, it is characterized in that: the outer wall at sleeve has 2～6 vertical ribs vertically.
The good effect that the utility model produces owing to described structure is conspicuous, promptly when concrete connecting reinforcement joint, can reach the maximum that connects defined with common pipe wrench or other instrument easily and screw moment, and be unlikely to skid, the uniformity of connection is guaranteed, thereby guaranteed the quality and the speed that connect.
Description of drawings
The utility model has following accompanying drawing:
Accompanying drawing 2 is the schematic cross-section of the utility model 6 rib embodiment;
Accompanying drawing 3 is the schematic cross-section of the utility model 3 rib embodiment;
Accompanying drawing 4 is the schematic cross-section of the utility model 2 rib embodiment.
In the accompanying drawing, 1---branch sleeve, 2---indulged rib.
The specific embodiment
Described structure of the present utility model is further specified by the non-limiting embodiment that accompanying drawing provides.
The vertical rib of the outer wall of branch sleeve 1 is 2～6.Described vertical rib 2 can be divided equally the circumference of branch sleeve 1 outer wall.
Referring to accompanying drawing 2, in the accompanying drawings, be evenly equipped with 6 vertical ribs 2 on the outer wall circumference of branch sleeve 1 vertically.
Referring to accompanying drawing 3, in the accompanying drawings, be evenly equipped with 3 vertical ribs 2 on the outer wall circumference of branch sleeve 1 vertically.
Referring to accompanying drawing 4, in the accompanying drawings, be evenly equipped with 2 vertical ribs 2 on the outer wall circumference of branch sleeve 1 vertically.
The utility model is applicable to II, III level, the hot rolled ribbed steel bar of Φ 20～Φ 40.
Claims (2)
1, a kind of rolling straight thread ribbed sleeve comprises branch sleeve (1), it is characterized in that: the outer wall at branch sleeve has 2～6 vertical ribs (2) vertically.
2, rolling straight thread ribbed sleeve according to claim 1 is characterized in that: described vertical rib (2) is divided equally the circumference of branch sleeve (1) outer wall.
