Abstract
The utility model provides a concrete member for testing. Bulgy leg parts are arranged on the concrete member, preformed holes are formed in the leg parts, a screw rod penetrates through the preformed holes, nuts are arranged at two ends of the screw rods and can rotate along the screw rod, and the concrete member is loaded by rotating the nuts at two ends of the screw rod. With the adoption of the technical scheme, the loading method is reliable in stress, the loading device is simple in structure and convenient to operate, the loading process of the concrete member during testing can be greatly simplified, the concrete member can be loaded while the erosion environment is simulated, and erosion conditions of a tensile region and a pressed region under the same environment condition can be compared.
Description
Technical field
The utility model relates to concrete load test field, particularly simulates the test under erosion environment and long-term constant load coupling.
Background technology
At present, study the test of long-term constant load on the concrete component impact, basically be all to be undertaken by the mode of weight loading, hydraulic loaded or mechanical load, the device space all smaller (as carbonization case, salt fog cabinet etc.) due to the simulation erosion environment, and that the loader of above-mentioned three kinds of load modes has a volume is large, floor area is wide, and loading is rear moves or adjusts very inconvenient drawback, causes testing being difficult to effectively when erosion environment is simulated, concrete component be loaded.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model has designed a kind of concrete component with protruding shank, this concrete component can use less equipment to obtain long-term constant load, and the simulation that can effectively solve erosion environment is difficult to the technical matters of carrying out simultaneously with loading.
The technical scheme that its technical matters that solves the utility model adopts is: design, with the shank concrete component, in shank position, two ends, be provided with symmetrical preformed hole, and the center of circle of two preformed holes is on same axis.
Threaded screw rod is passed to above-mentioned preformed hole, and the thread screw two ends are provided with nut; By answering torque wrench to turn the screw rod top nut, load, and by the vibratory string frequency recorder, record the power sensor reading that is fixed on screw rod and carry out the controlled loading size.Between nut and concrete component, be provided with packing ring, increase lifting surface area.
Screw rod, nut and power sensor spray with anticorrosive paint, prevent the utensil corrosion, and the warranty test quality can recycle after off-test.
The beneficial effects of the utility model are, stressed reliable, the charger simple structure, easy to operate of loading method, the loading procedure of concrete component in short form test greatly, and can in the simulation erosion environment, to concrete component, load, under same environmental conditions, can contrast tensile region and compressive region erosion condition.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is a kind of structural representation of testing with concrete component of the utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is a kind of outboard profile of testing with concrete component of the utility model.
1. nuts in figure, 2. pad, 3. screw rod, 4. power sensor, 5, shank, 6. concrete component, 7. preformed hole.
Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is further described.
As in Fig. 1, Fig. 3 in the contact site of screw rod 3 two ends and concrete component 6; put successively pad 2, nut 1; the lifting surface area that pad can increase while loading plays the effect of protecting concrete component; during loading, by answering torque wrench rotating nut 1, and by the reading that the vibratory string frequency recorder records on the power sensor, the size that loads is effectively controlled.Screw rod 3 length in loading procedure between both sides shank 5 will shorten thereupon, shank 5 effect of being under pressure becomes compressive region and shank 5 becomes tensile region with lower area by the under tension effect, and the erosion condition to zones of different while being convenient to test like this contrasts.
