Abstract
A kind of historic building fire prevention inside and outside defect generaI investigation detection device based on traditional detection method.When historic building fire prevention inside and outside existing defects, according to defect type specific in Practical Project, non-destructive testing range is distinguished by percussion, complete to acquire wooden component surface defect data using rotatable graduated scale, using probe-type stretch graduated scale and endoscopic can tortuous nanometer-scale ruler can complete the undetectable internal flaw data arrived of traditional detection method.The Echtheit of holding member to greatest extent when to ancient building non-destructive testing, the generaI investigation content more horn of plenty of historic building fire prevention, testing result is made more to quantify, also scheme and construction etc. are repaired for wooden component in the future and valid data support is provided, simultaneously because equipment has different detection modes, every detecting instrument, tool are monistic in reduction conventional detection devices uses and replaces program, improves detection efficiency.
Description
Technical field
The present invention relates to a kind of historic building fire prevention inside and outside defect detecting devices based on traditional detection method.The present invention
Belong to historic building fire prevention non-destructive testing and historic building conservation technical field.
Background technology
China's ancient building is in addition to enclosed structure, and majority is using wooden component as main supporting member.Wooden member bodies belong to biological material
Matter, different from rigid materials such as cement, reinforcing bars, easily by ectocines such as temperature, humidity, occur drying shrinkage, mould, damage by worms, be rotten,
The different diseases feature such as cavity causes the inside and outside portion of the generation such as ancient building beam, column, a tree, used in making timber for boats, rafter damaged, while ancient architecture is by long-term use
Its mechanical property can be gradually reduced, and the wooden component in part also needs to meet inhabitation, exhibition, sightseeing while itself existing defects in addition
Etc. functions, there are certain safety risks.Domestic and foreign scholars attach great importance to timber and wooden component detection technique at present, for
The internal flaw of historic building structure continues on new technology, new equipment is updated and attempts, such as using stress wave, impedance
Instrument, ultrasonic wave etc. differentiate wooden component inside defect situation, but Yi Shang detection technique and equipment are to historic building fire prevention
Itself have it is minimally invasive, Gu should be retained for some cultural relics protection units's (ancient building) with special historical value in Practical Project
The Echtheit of building, the detection that every wooden component all carries out equipment is undoubtedly the secondary destruction to historical relic, while also increases inspection
The labor intensity of survey personnel.It need to be under the premise of ancient building surface and internal structure not be destroyed, using based on traditional detection method
Historic building fire prevention inside and outside defect generaI investigation detection device real non-destructive testing and internal External Defect are carried out to ancient building
Detail prospecting record and defect estimation, the safety to assess historic building fire prevention provides effective data and supports, while
Go out to need the range of non-destructive detecting device emphasis detection for screening.
At present to the traditional detection method of historic building fire prevention mostly using qualitatively visually discriminating, simple percussion, ruler are surveyed
The methods of amount, inside and outside portion was damaged to historic building fire prevention to be differentiated and safety evaluation, is lacked to the damaged number of wooden component inside
According to acquisition and detection, while traditional ruler can not meet the deep detection to wooden component inside different directions, lack wooden component
The quantized result of internal flaw brings the detection of further non-destructive detecting device puzzled and repairerment method to cause certain be stranded
It disturbs.
In face of current ancient building, mainly wooden component lacks that effective inside and outside is carried out on the basis of traditional detection method is general
The problem of survey and acquisition damaged data of checking, the present invention is proposed in a kind of historic building fire prevention based on traditional detection method
External Defect generally investigates detection device, is mainly measured using three-in-one External Defect, endoscopic multiangular measurement and hollowing detect
Instead of single, only one visual angle the measurement means of tradition, device can one by one be opened according to different detection contents, and detection finishes
Collapsible is a device, avoids construction and detects the numerous and diverse of Site Detection tool, is operated on the spot suitable for scene,
The census data to inside and outside defect is not only enriched, while the detection emphasis for late detection instrument draws a circle to approve range, to greatest extent
Protection ancient building Echtheit, improve detection efficiency and data acquisition accuracy.
Invention content
The purpose of the present invention：It is to provide a kind of historic building fire prevention inside and outside defect generaI investigation based on traditional detection method
Detection device.The device itself is light, suitable for ancient building onsite application, while can to historic building fire prevention inside and outside portion carry out it is more
The damaged data acquisition of function, reduces destruction of the detection device to wooden component Echtheit, and data are provided for historic building fire prevention repairerment
It supports.Improve the acquisition of historic building fire prevention defective data.
The mesh of the present invention is realized by following technical measures, in a kind of historic building fire prevention based on traditional detection method
External Defect generally investigates detection device.It is characterized in that when carrying out whole inside and outside portion's defects detection to historic building fire prevention, according to existing
The surface defect of field historic building fire prevention carries out surface percussion by cambered surface hollowing hammer to it, and damaged wooden component is locked by sound
Specific location, measure wooden component surface fracture width, shear crack length secondly by rotatable graduated scale, if inside crack compared with
It is deep then its depth is detected using the probe-type graduated scale that stretches.Crack simultaneously with internal empty/rotten hidden danger when, by interior
After surfing style nanometer-scale device button adjusts the angle (up/down/left/right) of endoscopic nanometer-scale ruler trip, stir forward interior
Surfing style nanometer-scale device button, endoscopic nanometer-scale device is exported by conveyer belt by the direction of setting, when endoscopic is received
The end of rice graduation apparatus collide wooden component it is not poor rotten or empty when will alarm, thus get the sky that wooden component inside occurs
Hole/rotten effective data.Such as the maximum gauge and volume of interior void, remaining about area, to repair the formulation of scheme
Quantized data is provided.
