Description
Technical field:
The utility model relates to a kind of prestressed anchor parts, particularly a kind of circular tower shape anchor plate.
Background technology:
Existing anchor plate becomes the tower structure of a hollow in shape substantially, it is made of a truncated rectangular pyramids, a round platform and four ribs, the stress under anchorage of this kind anchor plate is big and concentrated, 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, the patent No. of the applicant's application is: the anchor plate patent of invention of ZL02104893.2 is improved this, a kind of inner hollow has been proposed, profile has the anchor plate of the circular tower shape structure of 2～4 layers of step, 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 because the body of the tower profile between the every two-layer step of this anchor plate is smooth plane, through experimental results show that, the anchor plate that this body of the tower profile is a smooth flat is unfavorable for that pressure disperses, and the maximum value of concrete pulling stress is bigger under its anchor; And the frictional force of this anchor plate body of the tower and bearing capacity are also less, so its integrated carrying ability is lower.
The utility model content:
The technical problems to be solved in the utility model is: provide a kind of existing circular tower shape anchor plate is improved the circular tower shape anchor plate that back, product structure are more optimized, make the maximum value of concrete pulling stress under the anchor littler, the integrated carrying ability is further enhanced.
The technical scheme that solves the problems of the technologies described above is: a kind of circular tower shape anchor plate, it is the circular tower shape structure that a kind of inner hollow, profile have two-layer at least boss rank, the end face of column foot is a sinking anchor slab part, the body of the tower profile between every two-layer boss rank or for profile with ladder or for lobed profile or for profile with groove or for having the profile of projection and groove simultaneously.
Further technical scheme of the present utility model is: the bottom surface on described each layer boss rank---pressure-bearing surface is taper seat or disk.
Because adopt said structure, the circular tower shape anchor plate of the utility model is compared with original anchor plate has following beneficial effect:
1, the maximum value of concrete pulling stress is less under the anchor:
Because the body of the tower profile of the circular tower shape anchor plate of the utility model or for profile or for lobed profile or for profile or for having the profile of small embossment and groove simultaneously with groove with ladder, this structure can make the stress under anchorage more uniform diffusion, in addition, because the pressure-bearing surface on each boss rank of this anchor plate is taper seat or disk, the stress that concentrates on the anchor plate is delivered in the concrete along desirable angle of flare, thereby also can reduce tensile stress maximum value under its anchor, thereby can increase the safety of anchor plate, further improve the degree of safety of concrete component.
2, the integrated carrying ability height of anchor plate:
Because the profile of the circular tower shape anchor plate of the utility model has the two-layer at least boss rank as main supporting body, body of the tower profile or for profile or for lobed profile or for profile or for having the profile of projection and groove simultaneously with groove with ladder, and also can have projection or groove having on the profile of ladder, adopt this structure can also increase the frictional force and the bearing capacity of anchor plate body of the tower, thereby can improve the integrated carrying ability of anchor plate.
3, product is in light weight:
Because the body of the tower profile of the circular tower shape anchor plate of the utility model or for profile or for having than the profile of small embossment or for profile or for having profile simultaneously than small embossment and groove with groove with multistage ladder, this structure is compared with the smooth body of the tower of existing circular tower shape anchor plate, can alleviate the weight of anchor plate, volume also further reduces, thereby can reduce its cost of production.
4, overall structure is more optimized, and concrete casting is closely knit under the anchor of being more convenient for; Also more help simultaneously the laying of the site operation and the auxiliary reinforcement of anchor plate.
Below, the technical characterictic to the circular tower shape anchor plate of the utility model is further described in conjunction with the accompanying drawings and embodiments.
