Abstract
This utility model relates to a prestress structure anchor device using the horn tube which is used as the prestressed beam concrete component of the expressway, bridge and gymnasium and so on. It comprises a steel stranded wire (1), an intermediate plate (2), an anchor board (3), anchor bolster plate (4) and a corrugated pipe (6). The said anchor board (3) is set up in the head of the anchor bolster plate (4), the said intermediate plate (2) is inserted into the anchor board (3), characterized in: a horn tube (5) is set up between the said anchor bolster plate (4) and the corrugated pipe (6), the caudal region of the said anchor bolster plate (4) has the female screw thread, the big-end of the horn tube (5) has the male screw thread, the big-end of the horn tube (5) is spirally joined to the caudal region of the anchor bolster plate (4). The small end of the horn tube (5) which inserts and connects to the corrugated pipe (6) is the jib head cone; the said steel stranded wire (1) is set through inside the intermediate plate (2), the anchor board (3), the anchor bolster plate (4), the horn tube (5) and the corrugated pipe (6) in axial direction. This utility model is reliable to connect and very airtightness.
Description
Technical field:
The utility model relates to a kind of prestressed structure ground tackle that uses oviduct.Be used for prestressed girder concrete components such as speedway, bridge, stadiums.
Background technology:
Before the utility model was made, general prestressed structure was made up of steel strand, intermediate plate, anchor slab, anchor plate and bellows with ground tackle.Connected mode between its anchor plate and the bellows is: be wrapped with adhesive tape after directly inserting bellows in the anchor plate afterbody hole, the insertion depth and the intensity that is intertwined and connected all can not guarantee, bellows very easily skids off from anchor plate afterbody hole, can not guarantee the sealing performance requirement when following road grouting procedure.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of prestressed structure ground tackle that connects the use oviduct of reliable, good seal performance is provided.
The purpose of this utility model is achieved in that a kind of prestressed structure ground tackle that uses oviduct, comprise steel strand, intermediate plate, anchor slab, anchor plate and bellows, described anchor slab places the anchor plate head end, intermediate plate is inserted in the anchor slab, it is characterized in that: be provided with oviduct between described anchor plate and the bellows, described anchor plate afterbody has internal thread, and horn-tube main aspect has external screw thread, and horn-tube main aspect is screwed onto the anchor plate afterbody; The oviduct small end is a frustoconical, and the oviduct small end inserts bellows, and bellows is inserted into connection, and described steel strand axially are placed through in intermediate plate, anchor slab, anchor plate, oviduct and the bellows.
Because the utility model has adopted oviduct to adopt respectively to be threaded with anchor plate and bellows and has been connected with tapering, is difficult for slippage, so connect reliably, good seal performance is leaked possibility when reducing grouting.
Description of drawings:
Fig. 1 uses the prestressed structure of oviduct ground tackle Facad structure schematic diagram for the utility model.
Fig. 2 is the I enlarged drawing of Fig. 1.
Fig. 3 is the II enlarged drawing of Fig. 1.
The specific embodiment:
Referring to Fig. 1, the utility model uses the prestressed structure ground tackle of oviduct, is made up of steel strand 1, intermediate plate 2, anchor slab 3, anchor plate 4, oviduct 5 and bellows 6.Described anchor slab 3 places anchor plate 4 head ends, and anchor plate 4 afterbodys have internal thread, and described oviduct 5 big ends have external screw thread, and oviduct 5 big ends are screwed onto anchor plate 4 afterbodys; Oviduct 5 small ends are frustoconical, and oviduct 5 small ends insert bellows 6, are inserted into bellows 6 to be connected.Described anchor slab 3 is provided with taper hole, and intermediate plate 2 is inserted in this taper hole, and described steel strand 1 axially are placed through in anchor slab 3, anchor plate 4, oviduct 5 and the bellows 6, by the taper hole of intermediate plate 2 and anchor slab 3 the steel strand interlock is lived.
During use, elder generation by being screwed at the anchor plate afterbody, is fixed on horn-tube main aspect on the reinforcing bar template with anchor plate, cuts bellows according to cutting length, is enclosed within small end taper place of oviduct, just can be in the grouting of the periphery of anchor plate.After treating that peripheral concrete has been crossed defects liability period, just can be by the grouting of grouting mouth and the sealing off and covering anchorage of intermediate plate and anchor slab.
