Abstract
The utility model relates to a fixed end anchorage device for prestressed structure which comprises an anchorage seat 6, a clip 5, a spring 3 and a cover board 2; the clip 5 presents cone-shaped; the hole wall of the clip is provided with a screw thread; an anchorage seat hole 61 is arranged on the anchorage seat 6 in an axial direction; the right part of the anchorage seat hole 61 is a taper hole 611 opposite to the clip, and the left part of the anchorage seat hole 61 is a straight hole 612; the clip 5 and the spring 3 are respectively inserted into the taper hole 611 of the anchorage seat and the straight hole 612; the cover board 2 is arranged on the left end of the anchorage seat 6. Because the utility model is a fixed end anchorage device with a not built-in type, the utility model is easy to detect and convenient to replace.
Description
Technical field:
The utility model relates to a kind of prestressed structure with novel fixed end ground tackle.Be used for post-tensioned prestressed concrete members such as speedway, bridge, stadiums.
Background technology:
Employed fixed end ground tackle has two kinds of structural shapes in the general post-tensioned structure: P type ground tackle and H type ground tackle.P type ground tackle mainly is made of extruded sleeve, anchor plate, constraint circle and spiral bar; H type ground tackle mainly is made of embossing head, bar frame and constraint circle.These two kinds of ground tackles all must be pre-buried in advance, then concreting.If after concreting, find the ground tackle existing problems, concrete all must be removed, change ground tackle again, construction and detection are very inconvenient.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of non-pre-buried type fixed end ground tackle is provided, so that it is easy to detect, it is convenient to change.
The purpose of this utility model is achieved in that a kind of prestressed structure is with novel fixed end ground tackle, comprise anchoring part, intermediate plate, spring and cover plate, intermediate plate is tapered, its endoporus wall is provided with thread, axially offer the anchoring part hole on the anchoring part, anchoring part hole right part is and the corresponding taper hole of intermediate plate that left part is a straight hole, intermediate plate and spring are inserted in respectively in the taper hole and straight hole of anchoring part, and cover board arrangement is in the anchoring part left end.
Behind the concreting, steel hinge line penetrates concrete component, and reserves a segment length, and ground tackle embeds in the notch of built-in fitting bearing plate, and with steel hinge line forward respectively by intermediate plate and spring in the anchoring part hole.After the steel hinge line threading is finished, owing to the position-limiting action that closes with cover plate of carving of intermediate plate, steel hinge line can not withdraw from, and ground tackle plays fixation to steel hinge line.
Because the utility model is non-pre-buried type fixed end ground tackle, be easy to detect, it is convenient to change.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 scheme of installation of the present utility model.
The specific embodiment:
As Fig. 1, the utility model is a kind of prestressed structure with novel fixed end ground tackle.Mainly form by anchoring part 6, intermediate plate 5, pad 4, spring 3, cover plate 2 and hold-down screw 1.Intermediate plate 5 is tapered, its endoporus wall is provided with thread 51, anchoring part 6 is according to the specification difference, axially offer anchoring part hole 61, anchoring part hole 61 right parts are and the corresponding taper hole 611 of intermediate plate, and left part is a straight hole 612, and intermediate plate 5 and pad 4, spring 3 are inserted in respectively in the taper hole 611 and straight hole 612 of anchoring part 6, pad 4 places intermediate plate 5 left sides, and cover plate 2 usefulness hold-down screws 1 are installed in anchoring part 6 left ends.
During assembling, intermediate plate, pad and spring are put into the taper hole and the straight hole of anchor slab respectively, cover gland then, tighten hold-down screw, be assembled into the fixed end ground tackle.
Fig. 2 is a scheme of installation of the present utility model.As shown in Figure 2, the fixed end ground tackle is placed in the notch of bearing plate 7 ends that are embedded in advance in the concrete, with steel strand 8 insertion of turning left from the right side, until holding out against cover plate 2.When steel strand 8 insert, spring 3 pressurizeds, intermediate plate 5 is loosening along the taper hole of anchoring part 6, and steel strand can insert smoothly.After steel strand 8 inserted, spring 3 was replied, and compresses intermediate plate 4; The thread of intermediate plate 4 chokes steel strand 8 simultaneously, and steel strand 8 can not be extracted out backward, realizes fixation.
