Abstract
The utility model discloses a steel bar connecting sleeve, which is provided with an inner thread, wherein the sleeve wall is provided with inspection holes; and a distance between the center of the inspection hole and one end surface of the sleeve is equal to a distance between the center of the inspection hole and the other end surface of the sleeve; the inspection holes on the sleeve are a groove-shaped through hole; the axial center line of each groove-shaped through hole is overlapped with the axial center line of the sleeve; more than three inspection holes are formed in the sleeve and are uniformly distributed on the circumference wall of the sleeve; and a scale mark is arranged at one side of each inspection hole, the scale mark is vertical to the axial center line of each inspection hole, and the scale of the center of each scale mark is aligned to the center of each inspection hole. According to the utility model, through observation of the inspection holes, steel bar butting flat-ends which are screwed into the sleeve are gapless and the connecting surface between the steel bar butting flat-ends is overlapped with the center scale mark, and the design requirement can be achieved only according with the standard, therefore the steel bar connecting sleeve is qualified in quality. The steel bar connecting sleeve disclosed by the utility model can be used for rapidly detecting the connection state of the end part of the steel bar in the sleeve; and the detection mode is simple, convenient and rapid, accurate in result and suitable for large-area construction application.
Description
Technical field
The utility model relates to a kind of reinforcing steel bar connecting sleeve tube, and the hole is detected at the center that especially relates to a kind of reinforcing steel bar connecting sleeve tube.
Background technology
Reinforcing bar is connected with screw shell, adopt the method for cutting to peel a part off with screw-rolling machine in end reinforced vertical rib to be connected and cross rib exactly, directly be rolled into the ordinary straight screw thread then, couple together, form the connection of reinforcing bar with special straight screw sleeve.The centre position that this method must be docked at the reinforcing bar at two ends sleeve could guarantee effective connection of reinforcing bar, is the cardinal task concerning structural safety.Following problem in use often appears in straight screw sleeve: 1. end reinforced mantle fiber length is not up to standard in the process, and mantle fiber length must equal the length of sleeve 1/2, could the reinforcing bar at two ends be docked at the centre position of sleeve.2. in the butt joint construction, it is long or too short that reinforcing bar is screwed into sleeve, can not guarantee that all the reinforcing bar at two ends is docked at the centre position of sleeve.3. the reinforcing bar enemy is not tightened in the work progress, big slit is arranged between the steel bar end.Whether existing test mode is up to standard through torque spanner inspection sleeve moment values, and this method only is suitable for spot check, because the restriction of equipment and the difficulty of operation can not be carried out complete inspection to large-area construction.
The utility model content
The utility model technical problem to be solved provides a kind of reinforcing steel bar connecting sleeve tube, can carry out fast detecting to end reinforced connection status in sleeve, and it is simple and efficient to have detection mode, and the result is accurate, is fit to the characteristics that large-area construction is used.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of reinforcing steel bar connecting sleeve tube, and said sleeve has internal thread, on said sleeve wall, is provided with to detect the hole, and the center in said detection hole equates with the distance of sleeve both ends of the surface respectively.
The further improvement that the utility model is done is: said detection hole is a slit-like through-holes, and the shaft centre line of said slit-like through-holes overlaps with the shaft centre line of sleeve.The detection hole number that said sleeve is provided with is greater than three and be distributed on the sleeve circle wall.One side in said detection hole is provided with graduation mark, and said graduation mark is vertical with the shaft centre line that detects the hole, the center in the scale aim detecting hole, center of said graduation mark.
Adopt the beneficial effect that technique scheme produced to be: reinforcing bar is connected replacement with sleeve be welded to connect, energy-saving and cost-reducing, the reinforcing bar quality of connection is carried out quick test, make it to adhere to specification, raise labour efficiency.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the front view of the reinforcing steel bar connecting sleeve tube of the utility model;
Fig. 2 is the sectional view along A-A line among Fig. 1.
As shown in the figure: 1 sleeve, 2 detection holes, 3 graduation marks.
The specific embodiment
