Abstract

The utility model relates to a flat deadman anchor backing board, relating to a prestress anchor component. The anchor backing board shows a tower-shaped structure whose inner part is hollow and is provided with a loading plate; the anchor backing board is characterized in that the flat deadman anchor backing board is the square tower-shaped structure with two layers of square table loading plates; two reinforcing ribs are provided between two layers of the square table; one edge of the reinforcing rib is provided with a grouting hole, and an integral body is cast to form proper figure; the inclined degree of the inner bore of the anchor backing board is 2 DEG <= theta <= 4 drgrees, and the thickness of the rectangular square table loading plate, the tower body, and the reinforcing rib can be adjusted according to the needs of construction. The thickness h 1 of general rectangle square station loading plate is from 10 to 30 mm, and the thickness h 1 of the reinforcing rib is from 10 to 30 mm, and the thickness h 3 of the tower body is from 6 to 15 mm. The structure for the products of the flat deadman anchor backing board of the utility model is optimized for improving the stress distribution below the inner anchor inside of an anchorage area, giving full play to the load carrying properties of materials, and improving the degree of safety for a means; the products has the advantages of less size, less volume, less dead load, less cost, and convenient construction.

Description

Flat ground tackle anchor plate
Technical field:
The utility model relates to a kind of prestressed anchor parts, particularly a kind of flat ground tackle anchor plate.
Background technology:
Existing flat ground tackle anchor plate such as Fig. 5~shown in Figure 8: this anchor plate profile becomes three layers of rectangle squarer shape of a hollow substantially, constitute by three rectangle Fang Tai and tower body that three rectangle side's platforms are coupled to each other, on the length direction between first and second layers of rectangle side's platform, injected hole is arranged; This anchor plate is that monoblock cast is shaped.The deficiency that this structure exists is: one, and rectangle side's platform number of plies is many, and profile is relatively complicated, and each side's of carrying interstation contact is not enough, and anchor plate is stressed even inadequately; Its two, each rectangle side's platform is thiner, influences the degree of safety of structure; Its three, this anchor plate height dimension is too big, and is less from the part stress that first floor carrying rectangle side platform is far away, can not give full play to the carrying effect; Its four because the endoporus lengthwise dimension is bigger, the endoporus gradient is bigger, it is bigger at the exit knuckle away from the steel strand of axis to be positioned at the anchor plate both sides during stretch-draw, easily cuts off; Its five, appearance and size is bigger, weight is bigger, material consumption is more, the cost of production height.
Summary of the invention:
Technical problem to be solved in the utility model is: it is stressed even inadequately to solve existing flat ground tackle anchor plate, structural safety is not high enough, anchor plate length is oversize, the problem that appearance and size, volume are big, the material consumption is many, cost of production is high, a kind of product structure optimization is provided, can improve the degree of safety of the distribution of stress under anchorage in the anchorage zone, the load-carrying properties of giving full play to material, raising member, and product design size, volume reduce, product weight reduction, material consumption reduce, and cost reduces, the flat ground tackle anchor plate of easy construction.
The technical scheme that solves its above-mentioned technical problem is: a kind of flat ground tackle anchor plate, be tower structure, the band loaded plate of an inner hollow, it is characterized in that: described flat ground tackle anchor plate is the squarer structure that has two-layer rectangle side platform loaded plate, symmetry is arranged with two ribs between the two-layer rectangle side platform, on the ribs injected hole is arranged on one side, monoblock cast is shaped.
As another feature of the present utility model, described anchor plate endoporus gradient θ is than original little 1~4 °, generally gets 2 °≤θ≤4 °.
According to construction needs, described rectangle side platform loaded plate thickness h 1Be 10~30mm, the thickness h of ribs 2Be 10~30mm, body of the tower wall thickness h 3Be 6~15mm.
Because the flat ground tackle anchor plate of the utility model is only with the squarer structure of two-layer rectangle side platform loaded plate, compares with existing flat ground tackle anchor plate, has following beneficial effect:
1, owing to be only with the squarer structure of two-layer rectangle side platform loaded plate, two ribs is arranged between the two-layer rectangle side platform, be more conducive to stress and transmit downwards, anchor plate and stress under anchorage are distributed more become evenly, improve the degree of safety of anchor plate and concrete component;
2, the anchor plate size is dwindled, and particularly the short transverse size reduces significantly, is convenient to construction and installation, has reduced labour intensity to a certain extent;
3, described anchor plate endoporus gradient is than original little 1~4 °, and it is less at the exit knuckle away from the steel strand of axis to be positioned at the anchor plate both sides during stretch-draw, difficult cutting off;
4, simple shape, structure optimization is easier to production and processing;
5, the old anchor plate weight of existing three the square platforms of anchor plate weight ratio reduces significantly, reduces material consumption, saves manufacturing cost.

Fig. 1~Fig. 4: the flat ground tackle anchor plate structural representation of the utility model:
Fig. 1: right view Fig. 2: main (half section) figure that looks
Fig. 3: left view Fig. 4: overlook (half section) figure
Fig. 5~Fig. 8: existing flat ground tackle anchor plate structural representation:

The specific embodiment:
Embodiment:
A kind of flat ground tackle anchor plate, described flat ground tackle anchor plate is the squarer structure that has two-layer rectangle side platform loaded plate 1, symmetry is arranged with two ribs 2 between the two-layer rectangle side platform 1, 2 2One side ribs 2 1On injected hole is arranged, generally be that monoblock cast is shaped.
As the another conversion of the utility model embodiment, described anchor plate endoporus 4 gradients---be inner hole wall with the axis angle theta than original little 1~4 °, generally get 2 °≤θ≤4 °.
General described rectangle side platform loaded plate 1 thickness h 1Be 10~30mm, the thickness h of ribs 2Be 10~30mm, body of the tower 3 wall thickness h 3Be 6~15mm, also can increase and decrease according to the practice of construction needs.
