Abstract
The invention discloses a novel open type steel strand anchor which is mainly formed by a working anchor and a tool anchor. An upper working anchor ring and a lower working anchor ring are arranged on the upper surface and the lower surface of the working anchor respectively, and a steel strand is arranged in the middle of the working anchor. The upper working anchor ring and the lower working anchor ring are arranged on the steel strand in a sleeved mode and abut against a support arranged on the right side. An upper tool anchor block and a lower tool anchor block are arranged on the upper surface and the lower surface of the tool anchor respectively. The upper tool anchor block and the lower tool anchor block are arranged on the steel strand in a sleeved mode and are screwed up through bolts. The novel open type steel strand anchor realizes the purpose, is simple in structure, small in size, light in weight, easy to machine, low in cost, and convenient and fast and safe to construct, and can guarantee the fact that stress on the steel strand does not lose in the whole operation process without the need of secondary tensioning of the steel strand after the anchoring position of the unbonded prestress steel strand in a working state is changed.
Description
Technical field
The present invention relates to a kind of ground tackle, particularly relate to a kind of Novel open steel strand anchorage.
Background technology
Due to reasons such as urban construction and development or building functions changes, need to be reconstructed, be extended existing construction work.For the concrete floor system, the roof system that adopt non-bending steel cable, by the superstructure partial demolition, the high-stress state of the steel strand of remainder superstructure can not have any change, need to have a kind of ground tackle can be competent at this work.And traditional ground tackle is comprised of annular anchor cup and wedge intermediate plate, steel strand are through the anchor cup, and by the anchoring of wedge intermediate plate, due to its reasons in structure, it is only applicable to the steel strand anchoring of new construction.
Summary of the invention
The present invention is a kind of Novel open steel strand anchorage.Be intended to solve current traditional ground tackle because its reasons in structure scope of application is little, use the problems such as inconvenient.
The present invention is achieved in that a kind of Novel open steel strand anchorage, and this Novel open steel strand anchorage mainly contains work anchor and moveable anchor forms; On work anchor and below be respectively arranged with the anchor ring of working, lower work anchor ring, centre arranges steel strand; Upper work anchor ring, lower work anchor ring set hold out against with the bearing that is arranged on the right on steel strand; On moveable anchor and below instrument anchor block, lower instrument anchor block are set respectively; Upper instrument anchor block, lower instrument anchor block are enclosed within on steel strand, use bolt tightening.
Further, upper work anchor ring, lower work anchor ring set hold out against with bearing on steel strand, with bolt tightening, also use the wedge intermediate plate by steel strand anchoring.
Further, the steel strand hole formed between upper instrument anchor block, lower instrument anchor block is provided with silk mouthful.
The present invention has realized goal of the invention preferably, simple in structure, little, lightweight, the easy processing of volume, with low cost, easy construction, quick, safety, can guarantee after changing in running order un-bonded prestressed steel strand anchorage point, not loss of the stress of steel strand in whole operating process, without the two times tensioning of steel strand.
The accompanying drawing explanation:
Fig. 1 is Novel open steel strand anchorage structural representation provided by the invention;
In figure: 1, work anchor; 11, upper work anchor ring; 12, lower work anchor ring; 13, wedge intermediate plate; 2, moveable anchor; 21, upper instrument anchor block; 22, lower instrument anchor block; 23, silk mouthful; 3, steel strand; 4, high-strength bolt; 5, bearing.
The specific embodiment:
Specific implementation process is as follows: a kind of Novel open steel strand anchorage mainly contains work anchor 1 and moveable anchor 2 forms; On work anchor 1 and below be respectively arranged with the anchor ring 11 of working, lower work anchor ring 12; Centre arranges steel strand 3; Upper work anchor ring 11, lower work anchor ring 12 are enclosed within on steel strand 3 and hold out against with the bearing 5 that is arranged on the right; Work anchor 1 and moveable anchor 2 respectively all further are provided with 4 high-strength bolts 4 for high-strength bolt; The both sides of steel strand 3 are provided with wedge intermediate plate 13; On moveable anchor 2 and below instrument anchor block 21, lower instrument anchor block 22 are set respectively; Upper instrument anchor block 21, lower instrument anchor block 22 are enclosed within on steel strand 3, with high-strength bolt 4, tighten.Be provided with silk mouth 23 on the steel strand hole formed between upper instrument anchor block 21, lower instrument anchor block 22.
Upper work anchor ring 11, lower work anchor ring 12 are enclosed within on steel strand 3 and hold out against with bearing 5, with high-strength bolt 4, tighten and use wedge intermediate plate 13 by steel strand 3 anchorings; On moveable anchor, upper instrument anchor block 21, lower instrument anchor block 22 are enclosed within on steel strand 3, tighten with high-strength bolt 4.To need steel strand 3 cut-outs of removing part to get final product again, and then unload moveable anchor 2, ground tackle is started working, not loss of the stress of steel strand in whole work progress, and the prestressing force effect of remainder is unaffected.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
