Abstract

The utility model relates to a prestressed group-anchor anchoring device which is composed of a spiral rib, a flared pipe, an anchor plate, an anchor ring, a clamping sheet, a covering cap and an insulating spacer. The utility model is characterized in that the outer part of the anchor plate is provided with a short cylindrical annular cast-iron sleeve, one side surface of the cast-iron sleeve is fully vacant, and extra-high strength cement mortar is poured and cast on the inner part and the outer extension part of the cast-iron sleeve to form an anchor plate core; a middle round hole is used for the connection and insertion of the flared pipe which is made of the material of high density polyethylene, and the flared pipe and the anchor plate form a mutually inserted separate type structure; the insulation spacer made of special material is arranged between the anchor ring and the anchor plate; the covering cap is in plastic sealing design, and is fixed to the anchor plate by a screw. The prestressed group-anchor anchoring device realized by the technical scheme has the advantages of full sealing, property of full insulation, lighter weight of the anchor plate made of composite material, and smaller external dimension, and the utility model is favorable for the arrangement of the anchoring device on a tensioning end.

Description

The prestressed group anchorage ground tackle
Affiliated technical field
The utility model relates to the prestressed anchor that uses in a kind of building.
Background technology
Prestressing technique has had the history of decades in application in engineering, and ground tackle along with progress of science and technology, also to it proposes higher requirement during engineering is used as the critical component in the post-tensioned prestressing engineering, need constantly reform.Traditional prestressed anchor, anchor plate are to use full cast iron manufacturing, and weight is big, get rusty easily, and also can conduct electricity, and do 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, and some special engineering also requires ground tackle will have insulation function, and is lax with electrochemical corrosion and the electric heating of avoiding steel strand.
Summary of the invention
The purpose of this utility model is to provide a kind of novel ground tackle, under the prerequisite that guarantees its traditional function, makes it have performance totally-enclosed, all insulation, can also be applied to the external prestressing structure of interchangeable rope.
In order to achieve the above object, the utility model is achieved by the following technical solution: a kind of prestressed group anchorage ground tackle, form by spiral bar, oviduct, anchor plate, anchor ring, intermediate plate, block and insulation spacer, described anchor plate is composited by cast iron cover and two kinds of materials of Ultrastrength cement mortar, the anchor plate outside is short cylinder annular cast iron cover, the whole vacancies in one side, the whole vacancies in one side, portion and extension are watered with the Ultrastrength cement mortar and are built up tie plate core of anchor within it; Circular hole is used to patch oviduct in the middle of the anchor plate, and oviduct adopts high density polyethylene (HDPE) (HDPE) material, with the separate type of anchor plate for patching; Be furnished with the insulation spacer that special material is made between anchor ring and anchor plate; Block designs for plastic seal, is fixed on the anchor plate by screw.
A kind of prestressed group anchorage ground tackle by technique scheme realizes has performance totally-enclosed, all insulation, and the anchor plate weight that composite material is made is lighter, and appearance and size is littler, helps the layout of stretch-draw end ground tackle.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is structure member figure of the present utility model
Fig. 2 is an anchor plate structure chart of the present utility model
With reference to accompanying drawing, the utility model is made up of spiral bar 1, oviduct 2, anchor plate 3, insulation spacer 4, anchor ring 5, intermediate plate 9, block 6.
The specific embodiment
Described anchor plate 3 is composited by cast iron cover 7 and two kinds of materials of Ultrastrength cement mortar, wherein the Ultrastrength cement mortar mainly adopts cement, fine sand and efficient additive to be made, the anchor plate outside is short columniform cast iron overcoat 7, one side vacancy, portion and extension are watered with the Ultrastrength cement mortar and are built up tie plate core of anchor 8 within it, and middle circular hole is used to patch oviduct.This design make water the tie plate core of anchor 8 that builds up, ordinary concrete by cast iron overcoat 7, high-strength cement mortar from the pressure of anchor ring 5 the power transmission circuit progressively, gradient is arranged be delivered to above the member, avoided the sudden change in the power transmission process, make structure stress more reasonable, than full forged iron anchor backing plate, this anchor plate weight is lighter, appearance and size is littler, helps the layout of stretch-draw end ground tackle.
Described oviduct 2 adopts high density polyethylene (HDPE) (HDPE) to make, adopt the separate type that can patch between oviduct 2 and the anchor plate 3, when needs changed rope, oviduct 2 can be extracted out from anchor plate 3 with the steel hinge line rope, made that changing Suo Zhenzheng becomes possibility; Oviduct 2 adopts nonconducting high density polyethylene (HDPE) (HDPE) material, has guaranteed steel hinge line and extraneous insulation in the duct.
Be furnished with the insulation spacer 4 that the special insulation material is made between the anchor ring 5 of ground tackle and anchor plate 3, this insulation spacer 4 is thin annulus, and race diameter is consistent with the external diameter of anchor plate 3, and middle opening diameter is consistent with the external diameter of anchor plate 3 circular vacancies.This insulation spacer has guaranteed the insulation between anchor ring 5 and the anchor plate 3, is to avoid steel hinge line to be subjected to the important component part of extraneous current affects.
Block 6 adopts plastic material to make, and is fixed on the anchor plate 3 by screw, and it is the containment member that vacuum aid grouting is carried out in the duct, guarantees steel hinge line and external insulation simultaneously again.
The utility model has adopted spiral bar 1 the same with traditional ground tackle and intermediate plate 9, uses with the exchange that makes things convenient for intermediate plate and spiral bar between the utility model and the traditional ground tackle, and also having avoided needs the replacing prestress tensioning equipment because of use of the present utility model.
