Description
Technical field
The present invention relates to temperature detection technology in construction work field, be specifically related to a kind of wireless temperature Real-time Collection equipment and acquisition method.
Background technology
Often construction is related to, as high-rise building basis, large equipment base, water resources dam etc. in modern architecture.Its main feature is exactly that volume is large, and general entity minimum dimension is more than or equal to 1m.Each main equipment has corresponding requirements to temperature in work progress, and even temperature requirements is very strict.Such as concrete construction, its surface coefficient is smaller, and hydration heat of cement release ratio is more concentrated, and the inner ratio that heats up is very fast.When temperature difference between inside and outside concrete is larger, concrete can be made to produce thermal cracking, affect structural safety and normal use.So fundamentally must be analyzed it, ensure the quality of constructing.
Structure is abundant, and amount of concrete is large, engineering specifications complexity (being all generally underground cast-in-place reinforced concrete structure), and construction technical requirement is high, and hydration heat of cement comparatively large (expectation is more than 25 degree), easily makes works produce temperature deformation.Except minimum cross section and internal and external temperature have certain regulation, also there is a definite limitation to planar dimension.Because planar dimension is excessive, the TEMPERATURE FORCE that effect of contraction produces is also larger, as taked control temperature improper measures, when temperature stress exceedes the pulling force ultimate value that concrete can bear, then easily produces crack.
The crack of interior appearance, by the difference of the degree of depth, is divided into through crack, deeper clefts and surface crack three kinds.Through crack develops into deeper clefts by concrete surface crack, finally forms through crack.It has cut off the section of structure, and may destroy globality and the stability of structure, its harmfulness is more serious; And deeper clefts has partly cut off structure section, also there is certain harmfulness; The general harmfulness of surface crack is less.
Generation crack is mainly caused due to hydration heat of cement, constraint condition, outside air temperature change and concrete the factor of shrinkage.Temperature detection must be carried out to concrete inside and surface in time, carry out cooling or Insulation, prevent excessive temperature differentials.Such as, cement will produce a large amount of heats in hydration process, is the main source of internal heat.Because section thickness is large, hydration heat is gathered in inside configuration and not easily scatters and disappears, and the temperature of inside concrete is raised.The maximum temperature of inside concrete, occurs in 3 ~ 5 days after building mostly, when concrete inside and surface temperature difference excessive time, temperature stress and temperature deformation will be produced.Temperature stress becomes ratio with the temperature difference, and the temperature difference is larger, and temperature stress is also larger.When concrete tensile strength is not enough to resist this temperature stress, just start to produce thermal cracking.The easy main cause producing crack that Here it is.In addition, in construction period, the cracking that the change of outside air temperature is right has significant impact.Concrete internal temperature is the superposition by the adiabatic temperature of placing temperature, hydration heat of cement and concrete exothermic temperature three.Ambient temperature is higher, and concrete placing temperature is also higher.Ambient temperature declines, especially rapid drawdown, greatly increases the thermograde of outer concrete and inside concrete, produces thermal (temperature difference) stress, causes and occur crack.Therefore controlling surface temperature of concrete and the outside air temperature temperature difference, is also an important ring of crackle preventing.
In order to the Changing Pattern of the temperature rise grasped and cooling, and the temperature impact under various conditions of various material, need to carry out temperature monitor and control to concrete, comprise the layout to concrete measuring temperature point, thermometric temporal frequency, the selecting of temperature measurement tool.In thermometric process, when finding temperature difference more than 25 DEG C, insulation should be strengthened in time or delay to remove insulation material, producing thermal (temperature difference) stress and crack to prevent concrete.
(1) layout of point for measuring temperature---must representative and comparability.Along the height of building, should be arranged in bottom, middle part and surface, vertical measuring point spacing is generally 500 ~ 800 ㎜; Plane then should be arranged in edge with middle, and plane measuring point spacing is generally 2.5 ~ 5m.When use electric thermo-couple temperature timing, its insertion depth can according to actual needs with concrete condition and determine, generally should be not less than 6 ~ 10 times of thermopair external diameter, the layout of point for measuring temperature, distance corner and surface should be greater than 50 ㎜.
When adopting reserved thermometric hole method thermometric, a thermometer hole can only reflect the data of a point.Should not take the temperature by surveying differing heights position in vertical core along the method for hole variation in altitude thermometer.
(2) thermometric system---survey once at the every 2 ~ 4h of concrete temperature ascent stage, the temperature decline stage, every 8h surveyed once, should survey atmospheric temperature simultaneously.
All thermometer holes all should be numbered, and carry out the measurement of inside concrete different depth and surface temperature.
Thermometric work should be undertaken by through training, responsible special messenger.Thermometric record, should hand over person in charge of the technology aspect to read label, and as the control foundation to concrete construction and quality.
(3) the selecting of temperature measurement tool---in order to control two temperature difference inside and outside concrete in time, and the difference of verify calculation value and measured value, grasp concrete temperature at any time dynamic, traditional temperature measurement tool needs employing multiple, when adopting thermocouple thermometric, also need to coordinate common thermometer, to verify.Because concrete surface needs to carry out PROCESS FOR TREATMENT, effects on surface needs artificial fixed point thermometric workload larger.
Publication number is the utility model patent of CN 201605814 U, disclose the technology that a kind of and traditional thermometric mode is similar, before concreting, by the technical manual good temperature sensor of mounting arrangements at the scene, and to every temperature sensor numbering (user's definition).Every 100m
2cloth 3 sampled points, sampled point is arranged in quincunx, adopts RS-485 network layout.After concreting, user, according to the sampled point difference measuring concrete surface and internal temperature sensor, sets concrete internal temperature warning bound.Publication number is the utility model patent of CN 202372267 U, the technical matters that disclosed in it, telescopic concrete temperature measuring device solves is difficult to arrive coagulation for the hand-held thermometer of Traditional Man or temperature sensor in some narrow positions or reinforcing bar close quarters to build position thus the problem being difficult to detect concrete temperature, can not reduce thermometric workload and working strength.
Because the thermometric frequency after the thermometric and construction of work progress is high, rule is strict, and workload is very large, needs to be subject to the technician trained to be responsible for detection.The collection of conventional temperature, by general thermometer measure, is made a copy of by the mode of manual record, goes back to management unit with papery mode foldback.Period is easy to produce data sheet and loses, and the personal errors such as mistranscription, affect engineering construction progress and quality.The complicacy of tradition thermometric work increases integral construction difficulty, and easily occurs the invalid measuring point of test leakage or inaccurate measurement, affects data analysis and safeguards process.The construction quality difference problem caused because of thermometric is of common occurrence.
