Description
Technical field
The utility model relates to concrete test apparatus field, is specifically related to the adjustable concrete shrinkage test box of humiture.
Background technology
Growing along with economic construction, the large-scale construction such as large-scale infrastructure, town road bridge, water conservancy water conservancy project, civil construction is being carried out or is being about to carry out.And this kind of building be unable to do without the widespread use of concrete material, concrete shrinkage is its essential attribute, and can cause concrete cracking, therefore, how accurately to test concrete shrinkage, most important with safety to the cracking of evaluation structure thing.
At present, concrete contraction test is mainly carried out in retract chamber, is provided with air-conditioning and humidifier in retract chamber, shrinking test specimen is placed on the testing jig in retract chamber, after starting air-conditioning and humidifier, time sight record contraction data, carries out data processing and completes contraction test.
This contraction test carried out in retract chamber, Problems existing:
1, the leakproofness of retract chamber is difficult to effectively be ensured, and due to the contraction test specimen quantity in retract chamber more, test lot is not quite similar, testing crew turnover observational record every batch data time is indefinite, switch closes retract chamber door affects test environment humidity and temperature, thus affects the accuracy of test data.Or visiting and learning mutually, personnel stay indoor etc. all can affect ambient temperature and humidity, affects the accuracy of test data.
2, specially build a house as retract chamber, area occupied is large, and dirigibility is poor, and the larger energy consumption of power of air-conditioning and dehumidifier is high, and the contraction being difficult to carry out flexibly under different temperature and humidity conditions is tested, multinomial comparative study.
Utility model content
The purpose of this utility model is exactly for deficiency above-mentioned at present, and provides humiture adjustable concrete shrinkage test box.
The utility model comprises casing, cloche, support, one group of clock gauge, air-conditioning heating and refrigeration system, humidifier, dehumidifier, PLC control cabinet and casing crash roll, the top cover of casing has one group of hole, cradle top surface has one group of clock gauge mounting hole corresponding with hole, support front has one group of threaded hole corresponding with clock gauge mounting hole, support installing is at casing top, in the clock gauge mounting hole that one group of clock gauge is rack-mount, and be fastened by bolts, cloche is positioned at above one group of clock gauge, and be movably arranged on casing top, air-conditioning heating and refrigeration system for controlling temperature in casing are arranged on the side of casing, humidifier and dehumidifier for controlling casing humidity are arranged on the opposite side of casing respectively, PLC control cabinet controls air-conditioning heating and refrigeration system respectively by output module, humidifier and dehumidifier, casing crash roll is positioned at bottom half.
The height of described casing is 520 ~ 530mm.
Described hole is circular port.
The utility model advantage is: this device can ensure the humiture of test environment, personnel are avoided to come in and go out on the impact of humiture, not by the restriction of indoor conditions, have a set of test macro of one's own, adjustment can also test temperature and humidity conditions flexibly, realize the contraction test comparison research under different temperature and humidity conditions.
