Abstract
The present invention relates to a kind of methods with prestressing force hose clamp reinforced steel concrete structure, comprising the following specific steps 1) being equally spaced prestressing force hose clamp outside reinforced concrete structure, are risen with universal hose clamp batch or a word by hose clamp screw rod pre-screwing；2) prestressing force hose clamp is fastened using torque wrench, tightening torque value is set as predetermined value；3) deformation for considering reinforced concrete structure needs to carry out secondary fastening to prestressing force hose clamp there are torque decaying when prestressing force hose clamp is installed；4) black marking pen marking is used after the completion of fastening；5) check whether prestressing force hose clamp has stripped thread to loosen phenomenon, discovery, which has stripped thread to loosen phenomenon, to be replaced.The present invention is used cooperatively the adjustable controllable prestressing force hose clamp reinforcement means of torque wrench, both prestressing force can accurately be applied, the loss of prestress caused by the relaxation of later period steel can be prevented again, effectively improve the overall deformation ability, bearing capacity and the development in confined concrete crack of reinforced concrete structure.
Description
Technical field
The invention belongs to technical field of structural reinforcement more particularly to a kind of prestressing force hose clamp reinforced steel concrete structures
Method.
Background technique
Construction department's statistics shows, existing 7,000,000,000 m in China2In reinforced concrete structure building, there is half at present
Aging period, about 10~1,200,000,000 m have been stepped into above2Reinforced concrete structure building need to carry out strengthening reconstruction and can guarantee to pacify
It entirely uses.In addition, the Urbanization Construction in China is in new zone development and reconstruction of the old city town parallel, and the reinforcing of oriented old house changes
The trend of transition stage is made, so reinforcing great to the research significance of Structures Reinforced Technique.
Traditional reinforcement means is that reinforcement material is pasted onto surface of concrete structure using binder, since binder is deposited
The burn into aging the defects of, consolidation effect can have a greatly reduced quality.There is also one for the prestressed consolidation technology that have developed rapidly in recent years
A little problems, such as initial stage could will accurately apply prestressing force by complicated monitoring process, and the relaxation of later period steel can make pre-
Stress reduces, and the constraint for causing crack to be subject to and member section bearing capacity reduce.There are no convenient and efficient and long-term steady at this stage
Fixed reinforced concrete structure reinforcement means.
Summary of the invention
The purpose of the present invention is obtaining a kind of technology of adjustable controllable hose clamp reinforced steel concrete structure of prestressing force, with
Solve disadvantage existing in the prior art.
It is a kind of to use prestressing force hose clamp reinforced steel concrete knot the purpose of the present invention is what is be achieved through the following technical solutions
The method of structure, comprising the following specific steps
1) it is equally spaced prestressing force hose clamp outside reinforced concrete structure, is risen with universal hose clamp batch or a word by hose clamp
Screw rod pre-screwing；
2) prestressing force hose clamp is fastened using torque wrench, tightening torque value is set as predetermined value；
3) deformation for considering reinforced concrete structure is needed there are torque decaying when prestressing force hose clamp is installed to answering in advance
Power hose clamp carries out secondary fastening；
4) black marking pen marking is used after the completion of fastening；
5) check whether prestressing force hose clamp has stripped thread to loosen phenomenon, discovery, which has stripped thread to loosen phenomenon, to be replaced.
Further, the shape of the prestressing force hose clamp is selected as rectangular or circle according to the shape of reinforced concrete structure
Shape.
The beneficial effects of the present invention are:
(1) prestressing force hose clamp not will increase dead load from heavy and light；
(2) easy to operate, time saving and energy saving, torque is adjustable using the fixed hose clamp of the torque wrench that can set torque value；
(3) hose clamp structure is simple, cheap, obvious compared with steel fibre and prestress steel band economic benefit；
(4) small to original structure disturbance, construction reinforcement can be carried out on not damaging original structure basis；
(5) structural initial pre stress when reinforcing, can delay crack developing and give full play to steel to avoid excessive Stress resort
Band examining tensile behavior.
Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book is understood other advantages and efficacy of the present invention easily.
A method of with prestressing force hose clamp reinforced steel concrete structure, comprising the following specific steps
1) it is equally spaced prestressing force hose clamp outside reinforced concrete structure, is risen with universal hose clamp batch or a word by hose clamp
Screw rod pre-screwing；
2) prestressing force hose clamp is fastened using torque wrench, tightening torque value is set as predetermined value；
3) deformation for considering reinforced concrete structure is needed there are torque decaying when prestressing force hose clamp is installed to answering in advance
Power hose clamp carries out secondary fastening；
4) black marking pen marking is used after the completion of fastening；
5) check whether prestressing force hose clamp has stripped thread to loosen phenomenon, discovery, which has stripped thread to loosen phenomenon, to be replaced.
Further, the shape of the prestressing force hose clamp is selected as rectangular or circle according to the shape of reinforced concrete structure
Shape.
The present invention by adopting the above technical scheme, with the use of the adjustable controllable prestressing force hose clamp reinforcement means of torque wrench,
Not only it can accurately apply prestressing force, but also the loss of prestress caused by the relaxation of later period steel can be prevented, be answered in advance by outside
Power hose clamp forms radial constraint to armored concrete part, effectively improves overall deformation ability, the carrying of reinforced concrete structure
The development in ability and confined concrete crack.
Above-described embodiment is merely exemplary to illustrate the principle of the present invention and its effect, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology all without departing from the spirit and scope of the present invention, carries out modifications and changes to above-described embodiment.Cause
This, institute is complete without departing from the spirit and technical ideas disclosed in the present invention by those of ordinary skill in the art such as
At all equivalent modifications or change, should be covered by the claims of the present invention.
