Abstract
The utility model relates to a pre-buried type anchorage, which is composed of a corrugated pipe, a spiral bar, a constraint ring, a steel strand, an extruding head, a backing plate and a delamination steel bar bracket, wherein, the backing plate 6 is provided with two to six layers, each layer is provided with four to forty eight backing plates, and the backing plates of each layer are connected by the delamination steel bar bracket 7. The constraint ring 3 is arranged on the head of the corrugated pipe 1, one head of the steel strand 4, the spiral bar 2, the delamination steel bar bracket 7, the extruding head 5 and the backing plate 6 are buried in concrete 8. The other head of the steel strand is penetrated in the corrugated pipe 1 and is isolated from the concrete 8, the steel strand 4 is tightly held and wrapped by the extruding head 5 after the extruding head 5 is extruded, and the extruding head 5 is supported on the backing plate 6. The multilayer pre-buried type anchorage has the advantages of more reasonable stress and better anchoring effects.
Description
The utility model relates to a kind of pre-buried type ground tackle.
Existing ground tackle is an individual layer pre-buried type ground tackle (see figure 2), in the duct, use this ground tackle, post-tensioned prestressing directly passed to when mixing mud and coagulating soil when needs, the stressed plane that concentrates on, bad to concrete structure stress uniformity, particularly in vertical duct during concrete perfusion, the concrete leakiness can form the space at backing plate face (c face), forms tomography easily.
The purpose of this utility model is to provide a kind of stressed more be tending towards reasonable, the better multilayer pre-buried type of anchoring effect ground tackle.
For reaching above-mentioned purpose, solution of the present utility model is to change original individual layer pre-buried type ground tackle into multilayer, changes the backing plate of a monoblock into several fritter backing plate, for keeping globality, links with the layering Steel bar rack between every layer of each backing plate.
Owing to adopt said structure, the utlity model has following advantage:
1, adopts the anchoring of multilayer pre-buried type, make that concrete is stressed more to become reasonable.
2, can reduce concrete tomography cross-sectional area, make full use of anchoring space and material, form closely knit concrete binding anchored end.
Below, the architectural feature to the pre-buried type ground tackle of the utility model is further described in conjunction with the accompanying drawings and embodiments.
Fig. 1: the utility model pre-buried type ground tackle structure and user mode schematic diagram.
Fig. 2: existing pre-buried type ground tackle structure and user mode schematic diagram.
Embodiment
As shown in Figure 1, the pre-buried type ground tackle of the utility model is by bellows 1, spiral bar 2, constraint circle 3, steel strand 4, extrusion head 5, backing plate 6, layering Steel bar rack 7 is formed, constraint circle 3 is placed on the head of bellows 1, the steel strand 4 that disperse there is effect of contraction, 4 one of steel strand, spiral bar 2, layering Steel bar rack 7, extrusion head 5 and backing plate 6 are embedded in the concrete eight, the other end of steel strand is through in the bellows 1 and isolates with concrete eight, extrusion head 5 bonds steel strand 4 tightly after extruding, and be bearing on the backing plate 6,7 pairs of concrete eights of spiral bar 2 and layering Steel bar rack play strengthens the intensity effect, in order to make this ground tackle that enough stress under anchorage be arranged, the area of backing plate 6 is controlled at 4800mm
2～8500mm
2Between, simultaneously for concrete can be enriched wherein, the distance between every backing plate 6 should for keeping its globality, be of a size of 150～250mm between layering reinforcing bar 7 each layers of support in addition between 30～50mm.
Claims (4)
1, a kind of pre-buried type ground tackle, comprise bellows (1), spiral bar (2), constraint circle (3), steel strand (4), extrusion head (5), backing plate (6), it is characterized in that: described backing plate (6) has 2～6 layers, 4～48 every layer, connect by layering Steel bar rack (7) between each backing plate of each layer.
