Abstract
The utility model relates to a rebar positive-thread straight-thread connection structure which comprises a first reinforcing rod and a second reinforcing rod. Positive-thread straight threads are arranged at one end of the first reinforcing rod, positive-thread straight threads are arranged at the other end of the second reinforcing rod and right opposite to that of the first reinforcing rod, and two ends of a sleeve are respectively connected with the positive-thread straight threads on the first reinforcing rod and the second reinforcing rod and enable the first reinforcing rod and the second reinforcing rod to be connected and fixed. The connection structure is good in reliability, has high ductility and repeated tension and compression performance, is good in reliability, and is favorable for improvement of work efficiency.
Description
Technical field
The utility model relates to a kind of steel bar connecting structure, is specially a kind of positive silk straight thread that is used for fixing reinforcing bar and connects the anti-silk of replacement straight thread syndeton, belongs to the mechanical connection technical field of construction.
Background technology
The mode of reinforced bar straight thread mechanical connection is mainly adopted in the connection of reinforcing bar at present, according to the situation of waiting to connect position, reinforcing bar place, can select dissimilar sleeves for use.In construction, inevitably can have the fixing reinforcing bar of an end, to this situation, the traditional construction technology method is to adopt anti-silk to carry out the connection of reinforcing bar; But; In practice of construction, when the anti-silk of reinforcing bar is shelled rib, need change the cylindrical die roll in the process equipment; The replacing time need be used 3 ~ 4 hours usually according to workman's qualification, and this has reduced efficiency of construction greatly; And on-the-spot when carrying out the reinforcing bar connection, because reinforcing bar one end is fixed by concrete, another free end of reinforcing bar is owing to receive the interference of reinforcing bar crotch and field condition (template and all the other reinforcing bars), and it is qualified that very difficult quality with connecting portion connects.
The utility model content
To the above-mentioned deficiency of prior art, the main purpose of the utility model is to provide a kind of connection back reliability positive silk of reinforcing bar straight thread syndeton preferably.
The technical scheme of the utility model is following: the positive silk of reinforcing bar straight thread syndeton; It is characterized in that; Comprise first reinforcement bar and second reinforcement bar; Be provided with positive silk straight thread at an end of first reinforcement bar, also be provided with positive silk straight thread and be connected with positive silk straight thread on second reinforcement bar with first reinforcement bar respectively with first reinforcement bar is provided with the sleeve of screw thread over against, inwall two ends and first reinforcement bar is connected with second reinforcement bar at an end of second reinforcement bar and fix.
Further technical scheme, the positive silk straight thread length on said first reinforcement bar equates with length sleeve.
Further again, the positive silk straight thread length on said second reinforcement bar is 1/2 of length sleeve.
With respect to prior art, the utlity model has following remarkable result:
1, connect the back good reliability: the utility model makes tensile strength of reinforcement better after adopting the syndeton of positive silk straight thread, and has high ductibility and tensile and compressive property repeatedly, better reliability, and qualification rate promotes significantly.
2, improved operating efficiency: with respect to classical inverse silk straight thread construction syndeton, the utility model add change cylindrical die roll man-hour number of times still less, the operating efficiency when reinforcing bar rotates is higher, has also improved work efficiency of workers greatly.
Description of drawings
Fig. 1 is the explosive view of the positive silk of the utility model reinforcing bar straight thread syndeton.
Fig. 2 is the user mode figure of the positive silk of the utility model reinforcing bar straight thread syndeton.
Among the figure, 1-the first reinforcement bar, 2-the second reinforcement bar, 3-sleeve.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
As depicted in figs. 1 and 2, the positive silk of the reinforcing bar of the utility model straight thread syndeton comprises first reinforcement bar 1 and second reinforcement bar 2, and wherein first reinforcement bar 1 or second reinforcement bar, 2 common ends are fixed in the concrete, and the other end is exposed outside.Fixing in the construction for first reinforcement bar 1 is connected with second reinforcement bar 2, be provided with positive silk straight thread at an end of first reinforcement bar 1, an end of second reinforcement bar 2 also be provided with positive silk straight thread and with first reinforcement bar 1 over against.During connection, inwall is provided with screw thread sleeve 3 two ends respectively with first reinforcement bar 1 and second reinforcement bar 2 on positive silk straight thread is connected and first reinforcement bar 1 is connected with second reinforcement bar 2 and fix.The sleeve 3 that uses in the utility model is existing parts; Wall is provided with straight thread within it; For described two reinforcement bars and sleeve 3 are complementary; Positive silk straight thread length and sleeve 3 equal in length on first reinforcement bar 1, the positive silk straight thread length on second reinforcement bar 2 is 1/2 of sleeve 3 length.Like this; During installation; Earlier sleeve 3 is enclosed within on first reinforcement bar 1, and with making sleeve 3 concordant with the end of first reinforcement bar 1 after sleeve 3 precessions, an end that then second reinforcement bar 2 is processed with positive straight thread aligns with an end of first reinforcement bar, 1 upper joint sleeve tube 3; Subsequently sleeve 3 is screwed out from first reinforcement bar 1; And be enclosed within simultaneously on second reinforcement bar 2, after sleeve 3 screwed in the positive silk straight thread on second reinforcement bar 2 fully, sleeve 3 just connects between first reinforcement bar 1 and second reinforcement bar 2 and with the two to be fixed.
In the utility model, the length of positive silk straight thread can be set according to demand flexibly on first reinforcement bar 1 and second reinforcement bar 2, firmly is purpose being connected with sleeve 3.
Claims (3)
1. the positive silk of reinforcing bar straight thread syndeton; It is characterized in that; Comprise first reinforcement bar (1) and second reinforcement bar (2); End at first reinforcement bar (1) is provided with positive silk straight thread; Also be provided with positive silk straight thread and be connected with positive silk straight thread on second reinforcement bar (2) with first reinforcement bar (1) respectively with first reinforcement bar (1) is provided with the sleeve (3) of screw thread over against, inwall two ends and first reinforcement bar (1) is connected with second reinforcement bar (2) at an end of second reinforcement bar (2) and fix.
