Abstract
The utility model belongs to a round tower-shaped anchor pad plate, which relates to a prestressing component of an anchor tool. The utility model is in a tower-shaped structure with a hollow inner part, the form of the utility model is in a round tower-shaped structure with steps, tower feet are round load-bearing steps for placing anchor plates, the utility model is formed by integral cast, the steps have four to ten layers, a pressure-bearing surface C at the lower surface of each step is a conical surface, the bevel angle of each conical surface and the horizontal surface is alpha = 10 DEG-40 DEG, a corresponding surface D of the pressure-bearing surface C of each step is a circular arc surface, the size of each circular arc is R = 15-50MM, the size of each arc is R = 15-50MM, the corresponding surface D and the pressure-bearing surface C are casting round angle transition, the thickness of each step is phi 2 = four to ten MM, and the wall thickness of the tower body is phi 1 = 7-40MM. The round tower-shaped anchor pad plate has the advantages that the structure is even more optimized, the anchor lower stress is smaller, and the distribution is more uniform; the safety of the anchor plate and concrete components is further enhanced, the form size of the anchor plate is further reduced by 5-10%, the weight is lightened by 0.15 kg / hole, and the manufacturing cost is reduced.
Description
Technical field:
The utility model relates to a kind of prestressed anchor parts, particularly a kind of anchor plate.
Background technology:
Become the tower shape of a hollow on the existing anchor plate profile substantially, constitute by a truncated rectangular pyramids, a round platform and four ribs, this kind anchor plate stress under anchorage is big and concentrated, and the angle of inner outer ring steel strand of anchor plate and axis is bigger, and appearance and size, volume are big, the material consumption is many.For this reason, anchor plate patent of invention (the patent No.: ZL02104893.2) this is improved of the applicant's application, the tower structure that a kind of inside is hollow has been proposed, profile has the anchor plate of the circular tower shape structure of 2～4 layers of step (referring to Fig. 4～Fig. 5), this anchor plate makes in the anchorage zone distribution of stress under anchorage more reasonable, product is from heavy and light, material consumption is few, cost is low, but through experiment, think and also be necessary to improve, this numbers of steps very little, counter stress disperses not enough, and pressure-bearing surface is plane or the dish form of caving in, and is unfavorable for that pressure disperses, and the concrete stress under anchorage is bigger.
The utility model content:
Technical problem to be solved in the utility model is: provide a kind of ZL02104893.2 anchor plate patent of invention is improved circular tower shape anchor plate back, that product structure is more optimized, disperse to be more conducive to pressure, the concrete stress under anchorage is further reduced.
The technical scheme that solves its above-mentioned technical problem is: a kind of circular tower shape anchor plate, be the tower structure of an inner hollow, its profile is a circular tower shape structure with the level, and column foot is the part of sinking anchor slab, monoblock cast is shaped, and it is characterized in that: described step has 4～10 layers.
Another feature of the present utility model: below each layer step---pressure-bearing surface C is a taper seat, oblique angle α=10 of itself and horizontal plane °～40 °.
Another feature of the present utility model is: the corresponding surface D of described each layer step pressure-bearing surface C is an arc surface, and the circular arc size is R=15～50mm, and this corresponding surface D and pressure-bearing surface C are curving of castings transition.
All the other features of the present utility model are: described step thicknesses is δ 2=4～10mm; Described body of the tower wall thickness is δ 1=7～40mm; The part of described column foot sinking anchor slab is circular carrying step.
Because adopt said structure, circular tower shape anchor plate of the present utility model is compared with existing circular tower shape structure anchor plate, has the following advantages:
1. stress under anchorage littler, distribute and more to become even:
Because the step number of plies of the utility model circular tower shape anchor plate is many, by multi-support face combination pressure-bearing, adopt taper seat pressure-bearing and arc surface corresponding simultaneously, pressure is disperseed away, make stress under anchorage littler, distribute and more to become even, stress value reduces more than 30% than old anchor plate, reduces 5%～15% than original circular tower shape structure anchor plate, has further improved the degree of safety of concrete component;
2. thicken the wall thickness of anchor plate, make body of the tower directly bear the pressure of anchor slab, increase the degree of safety of anchor plate;
3. anchor plate appearance and size further dwindles 5～10%, and reinforcing bar cuts off quantity to be reduced;
4. overall structure is more optimized, and concrete casting is closely knit under the anchor of being more convenient for;
5. the old anchor plate of the utility model circular tower shape anchor plate weight ratio on average alleviates the 0.4kg/ hole, on average alleviates the 0.15kg/ hole than original circular tower shape structure anchor plate, further reduces material consumption, has reduced manufacturing cost.
Description of drawings:
Fig. 1～Fig. 3: the circular tower shape anchor plate structural representation of the utility model:
Fig. 1-master looks sectional view, the left view of Fig. 2-Fig. 1, and the vertical view of Fig. 3-Fig. 1,
Fig. 4～Fig. 5: the anchor plate structural representation of existing circular tower shape structure:
Fig. 4-master looks sectional view, the vertical view of Fig. 5-Fig. 4.
The specific embodiment:
A kind of circular tower shape anchor plate, as Fig. 1～shown in Figure 3: this anchor slab is that an inner hollow, profile are the circular tower shape structure of 5 layers of step, column foot is the circle carrying step of sinking anchor slab, monoblock cast is shaped, described step is of five storeys, below each layer step---pressure-bearing surface C is a taper seat, oblique angle α=10 of itself and horizontal plane °～40 °; The corresponding surface D of each layer step pressure-bearing surface C is an arc surface, and the circular arc size is R=15～50mm, and this corresponding surface D and pressure-bearing surface C are curving of castings transition.
Described body of the tower wall thickness is δ 1=7～40mm, and step thicknesses is δ 2=4～10mm.
Tapering β=2～5 of the taper hole of its hollow °.
As a kind of conversion of the utility model embodiment, the number of plies of described circular tower shape anchor plate step can also increase or reduce, and is generally 4～10 layers.
As a kind of conversion of the utility model embodiment, the column foot of described sinking anchor slab part also can be other shapes, and as original tubular type, but its structure is with circle carrying step optimum.
