The clamping piece type finished twisted steel anchor is characterized in that internal threads are formed on the inner walls of the two clamping pieces, respectively, and correspondingly matched with external threads formed on finished twisted steel needing to be anchored, the inner wall of the outer ferrule is provided with a conical surface, the outer walls, fitted with each other oppositely, of the two clamping pieces also are provided with conical surfaces, and the tapers of the conical surfaces of the oppositely fitted outer walls of the two clamping pieces are consistent with the taper of the conical surface of the inner wall of the outer ferrule. The clamping piece type finished twisted steel anchor is simple in structure, quick to mount, reliable in anchoring, and capable of reducing the labor intensity, shortening the anchoring time and improving the production efficiency.
Description
Technical field
The utility model relates to pre-stress construction fixture, is specifically related to a kind of clip type finish rolling deformed bar ground tackle.
Background technology
Fining twisted steel reinforcing bar is used in prestressed architecture member, needs anchoring.Conventional anchorage style is directly to adopt tool-type stretch-draw nut, but in work progress, and tool-type stretch-draw nut need to rotate very long distance when can reach the position of stretch-draw jack, just becomes and wastes time and energy.While particularly there is situation that standard cap is all difficult to pass through smoothly at fining twisted steel reinforcing bar middle part, tool-type stretch-draw nut just is more difficult to pass through smoothly.The relevant personnel, in order to solve the problem that is connected of finish rolling deformed bar and stretch-draw nut, have proposed a kind of technical scheme, and CN 201330472 Y disclose a kind of twisted steel anchor device.This twisted steel anchor device is comprised of overcoat, hexagonal tie down screw, elasticity of plastics ring, left and right half round casing latch segment.Overcoat two ends have internal thread to be connected with hexagonal tie down screw, have the hole that can pass indented bars in the middle of hexagonal tie down screw, and one end endoporus has the conical surface coordinating with left and right half round casing latch segment.Left and right half round casing latch segment inner headed face respectively has the Baltimore groove corresponding with indented bars, respectively there is a taper surface at cylindrical two ends simultaneously, elasticity of plastics ring is arranged on half round casing latch segment inner side, left and right, indented bars passes hexagonal tie down screw hole from two ends, push elasticity of plastics ring open, insert in the half round casing latch segment of left and right, make indented bars convex slot just in time with left and right half round casing latch segment inner headed face in Baltimore groove, make left and right half round casing latch segment two ends end face respectively with overcoat hexagonal tie down screw inner conical surface close contact, make like this indented bars reach quick connection, and easy to assembly.But this twisted steel anchor device structure is more complicated, and can not be used for the prestressed, reinforced construction of fining twisted steel.
Summary of the invention
The purpose of this utility model is to provide a kind of clip type finish rolling deformed bar ground tackle, and it is simple for structure, quick for installation, and anchoring is reliable, can reduce labor intensity, and shortens the anchoring time, enhances productivity.
A kind of clip type finish rolling deformed bar ground tackle described in the utility model, comprise that outer cuff, two are semicylindrical intermediate plate, described two intermediate plates relatively outer wall of laminating coordinate with the inwall of described outer cuff, it is characterized in that: the inwall of described two intermediate plates is respectively equipped with internal thread this screw thread and the external screw thread corresponding matching needing on the finish rolling deformed bar of anchoring.
Described a kind of clip type finish rolling deformed bar ground tackle, also comprises an instrument backing plate, and the center of this instrument backing plate is provided with a through hole, and finish rolling deformed bar can pass from this through hole; The one side of described instrument backing plate is close to the end face of jack, an end face of another side and described outer cuff is close to.
Described a kind of clip type finish rolling deformed bar ground tackle, described in it, the inwall of outer cuff is taper seat, described two intermediate plates relatively outer wall of laminating are also taper seat, and relatively the fit tapering of taper seat of outer wall of described two intermediate plates is consistent with the tapering of described outer cuff circular conical surface of inner wall.
Further, on the outer wall of described outer cuff, be provided with two symmetrical planes.
How secondary the physical dimension of two intermediate plate inwall physical dimensions of the present utility model and the internal thread as required specifications and models design of the finish rolling deformed bar of stretch-draw anchor is, to adapt to the finish rolling deformed bar of stretch-draw anchor different size model.
The beneficial effects of the utility model: simple for structure, quick for installation, alleviated labour intensity, shortened the anchoring time, improved production efficiency; Because the tapering of outer cuff circular conical surface of inner wall is consistent with the tapering of the taper seat of two relative outer walls of fitting of intermediate plate, so, during stretch-draw anchor, draw tighter and tighter, so anchoring is reliable.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, described a kind of clip type finish rolling deformed bar ground tackle, comprises that outer cuff 1, two are semicylindrical intermediate plate 2, and described two intermediate plates 2 relatively outer wall of laminating coordinate with the inwall of described outer cuff 1; The inwall of described two intermediate plates 2 is respectively equipped with internal thread 21, this screw thread and the external screw thread corresponding matching needing on the finish rolling deformed bar 4 of anchoring.Also comprise an instrument backing plate 3, the center of this instrument backing plate is provided with a through hole, and finish rolling deformed bar 4 can pass from this through hole; The one side of described instrument backing plate is close to the end face of jack 5, an end face of another side and described outer cuff 1 is close to.
Described a kind of clip type finish rolling deformed bar ground tackle, described in it, the inwall of outer cuff 1 is taper seat, described two intermediate plates 2 relatively outer wall of laminating are also taper seat, and the tapering of the taper seat of the relative laminating outer wall of described two intermediate plates 2 is consistent with the tapering of described outer cuff 1 circular conical surface of inner wall.
Further, on the outer wall of described outer cuff 1, be provided with two symmetrical planes 11, so that spanner is clamped, carry out stretch-draw anchor.
While adopting the utility model as moveable anchor, first according to routine, jack 5 is installed, again two intermediate plates 2 are relatively fitted and clamped finish rolling deformed bar 4, then outer cuff is directly installed to two intermediate plate positions of laminating relatively from finish rolling deformed bar end cover, and be enclosed within the outside of two intermediate plates of relatively fitting, carry out afterwards stretch-draw anchor.Complete after stretch-draw anchor, lifting jack unloading is released intermediate plate from outer cuff.
Referring to Fig. 6 and Fig. 7, conventional anchorage style is directly to adopt tool-type stretch-draw nut 6, in work progress, when needing the very long distance of rotation can reach the position of stretch-draw jack, just becomes and wastes time and energy.While particularly there is situation that standard cap is all difficult to pass through smoothly at fining twisted steel reinforcing bar middle part, tool-type stretch-draw nut just is more difficult to pass through smoothly.
