Abstract
The utility model relates to a composite anchor backing plate, which comprises bearing plates with centre holes. The bearing plates are divided into a hollow intermediate steel iron backing plate and a composite bearing plate formed by ultra-high strength concrete pressure-bearing parts clad at the lower part or the periphery of the intermediate steel iron backing plate or clad at the lower part and on the circumference of the intermediate steel iron backing plate through the center part; the ultra-high strength concrete pressure-bearing parts clad at the lower part or on the circumference of the intermediate steel iron backing plate or at the lower part and the periphery of the of the intermediate steel iron backing plate through the center part are ultra-high strength reactive powder concrete components with the ultimate compression strength being larger than 120MPa and with the ultimate folding strength being larger than 12MPa; in general, the volume of the ultra-high strength concrete pressure-bearing part is larger than or equal to that of the intermediate steel iron backing plate part clad by the ultra-high strength concrete pressure-bearing part. The structure of the composite anchor backing plate is optimized, the steel iron material consumption is less, the cost is low, the anchoring stress is smaller, and the distribution of the anchoring stress tends to be evener; and the utility model facilitates the compact pouring of anchoring concrete, and also facilitates the on-site construction and the layout of the auxiliary concrete bars.
Description
Technical field:
The utility model relates to and a kind ofly higher concentrated stress is transmitted and is distributed to its compression strength value reliably with respect to the bearing plate in the low concrete building structures more than 3 times of steel and iron parts, particularly a kind ofly can and be distributed to the anchor plate that goes in the concrete anchoring district with the concentrated force transmission of ground tackle.
Background technology:
Concrete structure is made up of parts such as anchoring piece, anchor plate and stiffeners with ground tackle, anchoring piece 4 is lived presstressed reinforcing steel 3 anchorings, anchor plate 8 and reinforcement spiral reinforcement 6 then are embedded in the concrete seven (referring to Fig. 9, form clip type anchoring piece 4 by intermediate plate 41, anchor slab 42 among the figure, its anchoring piece also can be the anchoring piece of other types), the concentrated stress that anchoring piece passes over is disperseed, make it to be delivered in the concrete comparatively equably to go.Because often being delivered to, this concentrated stress surpasses 200MPa on the anchor plate, and concrete compressive strength generally the highest 60MPa of having only, tension are the highest has only 6MPa, so, be subjected to excessive stresses and ftracture, destroy for fear of concrete, the size of anchor plate can not be too little, and enough surface area dispersive stresses be arranged.At present, domestic anchor plate is that whole ironcasting or steel plate are made, and along with constantly riseing of price of steel product, its manufacturing cost is also more and more high.Therefore, urgently wish new technical scheme design bearing plate, substitute or the alternative steel of part, reach the purpose that reduces production costs by new cheap material.
Along with development of technology, concrete material can stably reach more than the 100MPa under factory's curing condition by optimization formula, and the highest even can reach 800MPa according to external report, the intensity with steel is suitable basically.Its cost is by weight less than half of steel, by volume then less than 1/4 of steel, so, this super high strength concrete and steel and iron parts is compound, may develop the lower bearing plate of cost fully.
The utility model content:
The purpose of this utility model be to provide a kind of product structure optimization, ferrous materials consumption less, cost is low, stress under anchorage is littler, the uniform combined type anchor padding plate that more becomes that distributes, to solve existing anchor plate consumption problem that ferrous materials is many, cost of production is high.
The technical scheme that solves the problems of the technologies described above is: a kind of combined type anchor padding plate, comprise the bearing plate of being with centre bore, described bearing plate be by core be the middle iron and steel backing plate of hollow and be coated in the middle of the combined type bearing plate that constitutes of the super high strength concrete pressure part of iron and steel backing plate bottom or periphery or bottom and periphery thereof.
Further technical scheme of the present utility model is: the volume of super high strength concrete pressure part that is coated on iron and steel backing plate bottom in the middle of the core or periphery or bottom and periphery thereof is more than or equal to the volume of iron and steel backing plate in the middle of the core.
Further again technical scheme of the present utility model is: its super high strength concrete pressure part that is coated on the middle iron and steel backing plate bottom of core or periphery or bottom and periphery thereof is a ultimate compressive strength〉120MPa, anti-folding ultimate strength is greater than the ultrahigh-strength active powder concrete member of 12MPa.
Because the combined type anchor padding plate of the utility model is to be that middle the iron and steel backing plate of hollow and the super high strength concrete pressure part that is coated on iron and steel backing plate bottom, centre and periphery thereof constitute by core, be equivalent between iron and steel backing plate and concrete that iron and steel is made, be provided with a transition anchorage zone of making by super high strength concrete, because the existence of this transition anchorage zone, enlarged concrete lifting surface area, so the size of middle iron and steel backing plate can be done smallerly.Thereby have a following beneficial effect:
1, stress under anchorage littler, distribute and more to become even:
Because the utility model combined type anchor padding plate is by middle iron and steel backing plate and is coated on the outer super high strength concrete pressure part combination pressure-bearing of middle iron and steel backing plate, its underpart and peripheral super high strength concrete thereof play transitional function, pressure after partly being delivered to the super high strength concrete pressure part, steel and iron parts is disperseed away, make under the anchor ordinary concrete stress littler, distribute and more become evenly, further improved the degree of safety of concrete component.
2, cost advantage is obvious:
Analyze through measuring and calculating, when super high strength concrete compressive strength reaches more than the 120MPa, rupture strength reaches 12MPa when above, by the reasonably optimizing dimensional parameters, the cost that then adopting super high strength concrete is increased can be wanted much less than the cost that reduces the steel and iron parts backing plate, and produced compound anchor plate possesses bigger cost advantage.
After the anchor plate material is become major part and is super high strength concrete by full cast iron, because the super high strength concrete cost is more much lower than steel, so greatly reduce manufacturing cost, cost than the bearing plate of ironcasting has on average reduced more than 15%, to consume 1.5 ten thousand tons of calculating of steel every year, then can save steel more than 2250 tons, have tangible economic benefit.
3, overall structure is more optimized, under the anchor of being more convenient for concrete casting closely knit, also be more conducive to the laying of site operation and auxiliary reinforcement.
Below in conjunction with embodiment the technical characterictic of a kind of combined type anchor padding plate of the utility model is further described.
