Abstract
The utility model discloses a prestressed anchor group anchorage, which comprises a spiral rib, a flared pipe, an anchor bearing plate, a gasket, an anchor ring, a clamp piece and a nut cap, wherein the anchor bearing plate main body is a hollow short cylindrical cast iron shell; an anchor bearing plate core formed by pouring extra-high strength cement mortar is arranged at the inner part and periphery of one side of the case iron shell; and a central hole for inserting the flared pipe is formed at the center of the anchor bearing plate. The prestressed anchor group anchorage has full-closed and full-insulated properties, and the anchor bearing plate has lighter weight and smaller shape, which facilitates arranging the tensioning end anchorage.
Description
Technical field
The utility model relates to a kind of prestressed anchor, particularly relates to a kind of prestressed group anchorage ground tackle.
Background technology
Along with progress of science and technology, people also have higher requirement to prestressed anchor.In traditional prestressed anchor, anchor plate is by full cast iron manufacturing, not only weight big, get rusty easily, also can conduct electricity, and not have sealing function.Along with further developing of engineering; Require prestressed structure that higher safety and durability are arranged; The appearance of vacuum aid grouting technology requires ground tackle to have sealing function; Some special engineering also requires ground tackle to have insulation function, and is lax with electrochemical corrosion and the electric heating of avoiding steel strand, and present prestressed anchor can not satisfy this demand.
Summary of the invention
The technical problem that the utility model will solve provides a kind of when having traditional function, has prestressed group anchorage ground tackle totally-enclosed, all insulation performance.
For this reason, the technical scheme of the utility model is following:
A kind of prestressed group anchorage ground tackle; Form by spiral bar, oviduct, anchor plate, pad, anchor ring, intermediate plate and block; It is characterized in that: the main body of described anchor plate is the short cylindrical cast iron cover of hollow; In the inside of this cast iron cover and a side outer be formed with the Ultrastrength cement mortar and water the tie plate core of anchor that builds up, this tie plate core of anchor centre is formed with the centre bore that is used to patch said oviduct.
Preferably, described pad is an insulation spacer, and described block and oviduct are processed by ambroin.
This prestressed group anchorage ground tackle has performance totally-enclosed, all insulation, and its anchor plate weight is lighter, and appearance and size is littler, helps the layout of stretch-draw end ground tackle.
Description of drawings
Fig. 1 is the structural representation of the prestressed group anchorage ground tackle of the utility model;
Fig. 2 is the structural representation of anchor plate in the utility model.
The specific embodiment
As depicted in figs. 1 and 2; The prestressed group anchorage ground tackle of the utility model is by spiral bar 1, oviduct 2, anchor plate 3, pad 4, anchor ring 5, intermediate plate 9 and block a shot and 6 form; The main body of anchor plate 3 is the short cylindrical cast iron cover 7 of hollow; In the inside of this cast iron cover 7 and a side outer be formed with the Ultrastrength cement mortar and water the tie plate core of anchor 8 that builds up, these tie plate core of anchor 8 centres are formed with the centre bores (figure does not mark) that are used for patching said oviduct.The Ultrastrength cement mortar is mainly processed by cement, fine sand and efficient additive.
In order to reach insulation effect, pad 4, block 6 and oviduct 2 are processed by insulation materials.
The feasible tie plate core of anchor 8 that passes through the cast iron external trepanning from the pressure of anchor ring 5 of said structure; The power transmission circuit that makes ordinary concrete progressively, gradient is arranged be delivered on the member has been avoided the sudden change in the power transmission process, makes structure stress more reasonable; Compare with full forged iron anchor backing plate; This anchor plate weight is lighter, and appearance and size is littler, helps the layout of stretch-draw end ground tackle.
Claims (2)
1. prestressed group anchorage ground tackle; Form by spiral bar, oviduct, anchor plate, pad, anchor ring, intermediate plate and block; It is characterized in that: the main body of described anchor plate is the short cylindrical cast iron cover of hollow; In the inside of this cast iron cover and a side outer be formed with the Ultrastrength cement mortar and water the tie plate core of anchor that builds up, this tie plate core of anchor centre is formed with the centre bore that is used to patch said oviduct.
2. prestressed group anchorage ground tackle according to claim 1 is characterized in that: described pad is an insulation spacer, and described oviduct is the oviduct that ambroin is processed.
