Abstract
The utility model provides a kind of round concrete tube chamber structure without support prestressed reinforcement equipment, including presstressed reinforcing steel and anchorage system, presstressed reinforcing steel lateral circular is on silo side wall, and pass through anchorage system stretch-draw anchor, the presstressed reinforcing steel is soap-free emulsion polymeization epoxy coating strand presstressed reinforcing steel, and the anchorage system is totally-enclosed no support anchorage system.The utility model quick construction, low in cost, safety of structure, durability can be effectively ensured, and have biggish Social benefit and economic benefit.
Description
Technical field
The utility model relates to round concrete silo structural strengthening fields more particularly to a kind of use presstressed reinforcing steel to carry out
The equipment that concrete silo is reinforced.
Background technique
Round concrete tube chamber structure is widely used in grain, cement, electric power, metallurgy industry.Because of design, constructional deficiency
Or improper use often results in bulkhead and generates the Vertical Cracks for being difficult to be closed and influence its service life.Traditional reinforcing
Method, which has, increases bulkhead section, and outside winding is carbon cloth reinforced, the methods of winding deformed bar.Before being used in Practical Project
The silo of two kinds of reinforcement means still cannot effective control critical eigenvalue development, and it is lower to wind common presstressed reinforcing steel efficiency, answers in advance
Frictional force between power muscle and bulkhead leads to greatly very much that effective prestressing force is low or quantity of reinforcement increases.Presstressed reinforcing steel outer layer protection mortar is easy
Cracking, structure durability are difficult to ensure.
How conveniently effectively to be reinforced to generating defect and silo currently in use, and guarantees that structure is durable
Property, reduce reinforcement cost will be problem to be solved in the utility model.
Summary of the invention
The utility model is to solve the above problems, provide a kind of round concrete silo knot easy to operate, durability is strong
Structure ruggedized equipment.
Circle concrete silo construction pre-stress ruggedized equipment described in the utility model, including presstressed reinforcing steel and anchorage body
System, presstressed reinforcing steel lateral circular pass through anchorage system stretch-draw anchor on silo side wall；The presstressed reinforcing steel is soap-free emulsion polymeization ring
Oxygen coating tendon of steel strand, the anchorage system are totally-enclosed no support anchorage system.
The soap-free emulsion polymeization epoxy coating strand presstressed reinforcing steel refers to: steel strand wires monofilament or integral spray have etch-proof ring
The unbonded prestressing tendon of oxygen resinous coat.
The totally-enclosed no support anchorage system refers to: pulling anchor cable stage can self-sustained, working stage can self-protection
Osculant presstressed reinforcing steel anchorage.
The utility model replaces common steel strand wires that can be greatly reduced between presstressed reinforcing steel and bulkhead using non-bending steel cable
Frictional force, significantly improve effective prestressing force, reduce quantity of reinforcement, the outer protective sleeves of steel strand wires, grease, epoxy coating are to steel strand wires
Three protection are formed, structure durability is effectively ensured.
Meanwhile construction journey can be reduced without otherwise designed installation anchoring pilaster using totally-enclosed no support anchorage system
Sequence reduces reinforcement cost.
It is more preferably designed as, the anchorage system is arranged along silo sidewall symmetry.Under this setting, it is looped around silo
Loss of prestress can reduce half when tension of prestressed tendon on side wall, and the precompression established after tensioning is more uniform.
The utility model reasonable stress is clear, can implement during production, not damaged to former library wall, without carrying out high-altitude mould
Plate and reinforced concrete construction, quick construction is low in cost, and safety of structure, durability can be effectively ensured, and has larger
Social benefit and economic benefit.
Detailed description of the invention
Fig. 1 is silo structure floor map；
Fig. 2 is silo structure diagrammatic cross-section；
Fig. 3 is silo structure expanded schematic diagram；
In figure: 1, soap-free emulsion polymeization epoxy coating strand presstressed reinforcing steel；2, totally-enclosed no support anchorage system；3, former bulkhead；
4, annular driven hanging basket.
Specific embodiment
Ruggedized equipment described in the utility model is for reinforcing round concrete tube chamber structure.
As shown in Figure 1, circle concrete tube chamber structure described in the utility model is without support prestressed reinforcement equipment, soap-free emulsion polymeization
Epoxy coating strand presstressed reinforcing steel 1 and totally-enclosed no support anchorage system 2, soap-free emulsion polymeization epoxy coating strand presstressed reinforcing steel 1
On silo side wall, totally-enclosed no support anchorage system 2 is symmetrically anchored at circular soap-free emulsion polymeization epoxy coating steel and twists lateral circular
1 two sides of line presstressed reinforcing steel.
The utility model reasonable stress is clear, can implement during production, not damaged to former library wall, without carrying out high-altitude mould
Plate and reinforced concrete construction, quick construction is low in cost, and safety of structure, durability can be effectively ensured, and has larger
Social benefit and economic benefit.
