Description

Prestressed structure is with novel connector ground tackle
Technical field:
The utility model relates to a kind of ground tackle.Especially relate to a kind of prestressed structure with novel connector ground tackle.Be mainly used in backward pull prestressed girders such as speedway, bridge, stadiums and connect concrete component.
Background technology:
Before the utility model was made, employed connector ground tackle was a LP type connector ground tackle in the general post-tensioned structure.LP type connector ground tackle is made of connector, extruded sleeve, constraint circle and spiral bar.Because the processing more complicated of connector, and generally all first split processing back extrusion molding, moreover because that the connector pressure-bearing surface that contact with extruded sleeve can not guarantee is very vertical with it, each root steel strand is stressed also inhomogeneous, so very easily slippage of extruded sleeve individually.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, provides the stressed more uniform prestressed structure of a kind of integral body with novel connector ground tackle.
The purpose of this utility model is achieved in that a kind of prestressed structure is with novel connector ground tackle, it is characterized in that it comprises: fixedly continued access anchor slab, left intermediate plate, adapter sleeve, spring, cover plate, activity continued access anchor slab and right clamping piece, described left intermediate plate and right clamping piece are tapered, offer the anchoring part hole on the described fixedly continued access anchor slab, anchoring part hole right part is a straight hole, left part is a taper hole, and spring and left intermediate plate are embedded at respectively in this straight hole and the taper hole, and cover plate is connected in fixedly continued access anchor slab right-hand member; Offer the anchoring part hole on the described activity continued access anchor slab, anchoring part hole left part is a taper hole, and right clamping piece is embedded in this taper hole; Described adapter sleeve inner hole wall is shaped on internal thread, fixedly is shaped on external screw thread on continued access anchor slab and the activity continued access anchor slab outside wall surface, and adapter sleeve is spun on fixedly on the continued access anchor slab and activity continued access anchor slab.
The utility model prestressed structure is provided with thread with novel connector ground tackle, described left intermediate plate and right clamping piece endoporus wall.
During installation, earlier by after the concreting, be fixed on activity continued access anchor slab in the notch of bearing plate by stretch-draw, the fixedly continued access anchor slab that will install left intermediate plate, spring and cover plate behind the adapter sleeve again of screwing on is screwed in the adapter sleeve, insert one of steel strand in wherein, owing to the position-limiting action that closes with cover plate of carving of left intermediate plate, steel strand can not withdraw from, and the other end that is exposed will can be used as continues the stretch-draw use.
Because the utility model adopts between two anchor slabs to being threaded, and is whole stressed more even, and be easy to installation.Because the utility model is whole the connection, be force-applied stretch-draw again behind the insertion steel strand again, reduce the time of hanging and tying up extruded sleeve, improve safety.
Description of drawings:
Fig. 1 is the structural representation of the utility model prestressed structure with novel connector ground tackle.
Fig. 2 for the utility model prestressed structure with novel connector ground tackle scheme of installation.
The specific embodiment:
Referring to Fig. 1, Fig. 1 is a kind of prestressed structure with novel connector ground tackle.It is mainly by fixedly continued access anchor slab 2, left intermediate plate 3, adapter sleeve 4, pad 5, spring 6, cover plate 7, hold-down screw 8, activity continued access anchor slab 9 and right clamping piece 10 are formed.Described left intermediate plate 3 and right clamping piece 10 are tapered, and its endoporus wall is provided with thread.Offer anchoring part hole 21 on the described fixedly continued access anchor slab 2, anchoring part hole 21 right parts are straight hole 211, left part is a taper hole 212, spring 6 and left intermediate plate 3 are embedded at respectively in this straight hole 211 and the taper hole 212, pad 5 is embedded between left intermediate plate 3 big ends and the spring 6, and cover plate 7 usefulness hold-down screws 8 are fixed in fixedly continued access anchor slab 2 right-hand members.Offer anchoring part hole 91 on the described activity continued access anchor slab 9, anchoring part hole left part is a taper hole 911, and right clamping piece 10 is embedded in this taper hole 211.Described adapter sleeve 4 inner hole walls are shaped on internal thread, fixedly are shaped on external screw thread on continued access anchor slab 2 and activity continued access anchor slab 9 outside wall surface, and adapter sleeve 4 is spun on fixedly on the continued access anchor slab 2 and activity continued access anchor slab.
Installation process such as Fig. 2: at first, activity continued access anchor slab 9 is placed in the notch of bearing plate 12 ends that are embedded in advance in the concrete, with steel strand 11 insertion of turning left from the right side, penetrate in the right clamping piece 10 in the anchoring part taper hole 91, utilize jack tension that activity continued access anchor slab 9 is pressed on bearing plate 12 notches, again adapter sleeve 4 one (right-hand member) is screwed on the external screw thread of activity continued access anchor slab 9 left ends to the length of fit that requires.Secondly, assemble fixedly continued access anchor slab 2 interior each parts separately, step is as follows: left intermediate plate 3 is put into the fixedly left part taper hole 212 of continued access anchor slab 2 from right-hand member, place pad 5 at left intermediate plate 3 big ends, again spring 6 is put into the fixedly right part straight hole 211 of continued access anchor slab 2 from right-hand member, cover plate 7 usefulness hold-down screws 8 are installed in the fixedly right-hand member of continued access anchor slab 2.The fixedly continued access anchor slab 2 that installs each parts other end (left end) from adapter sleeve 2 is screwed in to the length of fit that requires, when steel strand 1 insert from anchoring part hole 21 left ends, spring 6 pressurizeds, become flexible on the left intermediate plate 3 edges fixedly taper hole 212 of continued access anchor slab 2, and steel strand can insert smoothly.When steel strand 1 insert put in place after, spring 6 is replied, and compresses left intermediate plate 3, the thread of left intermediate plate is bitten steel strand 1 simultaneously, and steel strand 1 can not be extracted out backward, realizes steel strand 1 and the fixing fixation between the continued access anchor slab 2.Generally fixedly realized the effect that is connected by 4 of adapter sleeves between continued access anchor slab 2 and the activity continued access anchor slab 9, stretch-draw is stressed again to make the other end of steel strand.
