Description
Technical field
The invention belongs to building engineering construction field, and in particular to a kind of nuclear power station vertical prestressing conduit measurement auxiliary dress
Put.
Background technology
Prestressing force is in order to improve structure military service performance, in the compression that construction period is previously applied to structure, structure clothes
Pre-compression stress can completely or partially offset tension caused by load during labour, it is to avoid structure is destroyed.It is usually used in concrete knot
Structure, is before xoncrete structure bears load, to apply pressure to it in advance so as to the tensile region coagulation in external load function
Native internal force produces compression, to the tension for offsetting or reducing external applied load generation, makes structure in the condition of normal use not
Produce crack or split must be than later.
Before Engineering Structure Component bears external applied load, to the reinforcing bar in tension module, apply compressive pre-stress, improve component
Rigidity, postpone crack occur time, increase component durability.And vertical prestressing is more normal in building engineering construction
Prestressing force, vertical prestressing conduit is construction and installation system important in many building work progress, is building
The important component part of thing safety guarantee.
The problem that at present measurement of vertical prestressing conduit is present in nuclear power station：1. wooden nail device is adopted, it is impossible to completely
Laminating vertical prestressing conduit circular ports so that conduit installation accuracy is poor, cause the accuracy for measuring also poor；2. wooden nail
Sub-device needs heart special messenger in a device to set up measuring prism in measurement process, and the time is longer, and personnel's physical demand is larger, surveys
Amount personnel's efficiency is low.
The content of the invention
The technical problem to be solved be it is existing nuclear power station construction in vertical prestressing conduit installation accuracy compared with
Difference, measurement construction period are longer, therefore devise a kind of nuclear power station vertical prestressing conduit measurement servicing unit, after the device is
Continuous related building vertical prestressing conduit is installed and provides a kind of new measurement centralising device, by this device, it is possible to increase core
Vertical prestressing conduit installation accuracy in the construction of power station, shortens the measurement construction period, while reducing survey crew's labour intensity.
The present invention is achieved through the following technical solutions：
A kind of nuclear power station vertical prestressing conduit measurement servicing unit, including at the vertical prestressing conduit mouth of pipe
Positioning disk, the side wall of the positioning disk forms the cambered surface being mutually matched with the mouth of pipe of vertical prestressing conduit, pacifies on positioning disk
Equipped with connecting rod, and the center line of connecting rod and the center line of positioning disk overlap.In nuclear power station construction, apply vertical prestressing
It is very important measure, and the applying of vertical prestressing be unable to do without vertical prestressing conduit, vertical prestressing conduit is a lot
Construction and installation system important in building work progress, is the important component part of building safety guarantee, especially
In the construction to nuclear power station, important guarantee can be safely provided to its structure.But tradition is for vertical prestressing conduit
During measurement, it is fitted with vertical prestressing conduit using wooden nail device, and the mouth of pipe of vertical prestressing conduit is in
Circle, the damage or the wooden architectural characteristic of itself when wooden nail device adds man-hour because technique is unqualified, uses, all the time
Cannot completely be fitted vertical prestressing conduit circular ports so that conduit installation accuracy is poor, cause the accuracy for measuring also poor,
And then nuclear power station construction quality is affected, there is potential safety hazard, while wooden nail device needs in a device in measurement process
Heart special messenger sets up measuring prism, and the time is longer, and personnel's physical demand is larger, survey crew's inefficiency.Therefore this is devised
Device is led by the way that the side wall of positioning disk is formed as nuclear power station vertical prestressing conduit measurement servicing unit with vertical prestressing
The cambered surface that the mouth of pipe of pipe is mutually matched, cambered surface towards positioning disk centerline direction bends, and can more fit vertical prestressing conduit
Circular ports different size difference, adjustment position more levels off to mouth of pipe center, and it is used as vertical prestressing conduit measurement centering dress
Put, realization uses cooperatively on measuring prism head, and on the same line, certainty of measurement is higher for camera lens and pipeline, improves nuclear power station
The safety guarantee of work progress, quality meets and requires after building shaping, by the way that measuring prism is directly placed on servicing unit,
Survey crew's efficiency is improved, while the processing of device and combination are all very convenient, easy damaged, can not reuse, and shorten
Measurement construction period.
In order to by positioning disk and connecting rod fixation, meet use requirement, therefore in the top center of positioning disk
The groove being mutually matched with connecting rod face size is recessed, the bottom of connecting rod is arranged in a groove, while the bottom of groove
Portion is provided centrally with tapped through hole one, and the bottom of connecting rod is recessed screwed hole two, in tapped through hole one screw thread is provided with
Bar, and one end of threaded rod is inserted in tapped through hole two, by groove and the positioning mode of tapped through hole so that positioning disk with
Between connecting rod coordinate fastening, dismount it is all very convenient, can mass produced components changed.
Top surface also in positioning disk is recessed the different cannelure of some packet sizes, and center and the positioning disk of cannelure
Center superposition, the internal diameter size for being smaller in size than smallest size of cannelure of groove.Cannelure passes through lathe turner out,
Under not affecting the structural stability of positioning disk, the weight of device can be suitably reduced, installed in the mouth of pipe of vertical prestressing conduit
The extruding of line up wall is reduced afterwards, keeps the structural stability of the mouth of pipe, it is overall lighter, carry lighter.
Handle is also provided with above positioning disk, the two ends of handle are each passed through positioning disk and fix with positioning disk, in order to
Facilitate and can keep balance when lifting, be two secondary by the quantitative design of handle, it sets along the Central Symmetry of positioning disk
Put.
The present invention compared with prior art, has the following advantages and advantages：The apparatus structure is simple, beautiful outline form
Sight, easy to operate, use flexibly etc., it is used cooperatively with measuring prism head, measuring prism can be directly placed at into auxiliary dress
Put, improve measurement and the installation effectiveness of survey crew, reduce survey crew's labour intensity；And be fabricated to device bottom edge
Arc, the difference of mouth of pipe manufactured size of more fitting, can improve vertical prestressing conduit installation accuracy.The present invention is solved vertically
Situations such as prestressing force conduit installation accuracy is poor, the measurement construction period is longer.
