Abstract
The invention discloses a well-shaped test concrete component. The well-shaped test concrete component comprises an upper beam (5) and a lower beam (6), wherein both the upper beam (5) and the lower beam (6) are strip-shaped; holes are symmetrically formed in the two ends and close to the edge of both the upper beam (5) and the lower beam (6) in the length direction; a screw (1) penetrates through the holes formed in the two ends of both the upper beam (5) and the lower beam (6); nuts are mounted at the two ends of the screw (1) to connect the upper beam (5) and the lower beam (6) together; a cushion block (7) is sandwiched between the upper beam (5) and the lower beam (6) and is located at the central position of the upper beam (5) and the lower beam (6). The well-shaped test concrete component provided by the invention has the following beneficial effects: the test concrete component can acquire constant loads for a long term, and can carry out contrast test on the flexural property and erosion rule of the upper part and the lower part of concrete components with different mixing proportions and construction requirements under the same erosion environment and load conditions.
Description
Technical field
The present invention relates to a kind of intersecting parallels test concrete component, belong to proving installation technical field.
Background technology
At present, the erosion test of the manual simulation erosion environment of research concrete component under load action, is to be undertaken by the mode of weight loading, hydraulic loaded or mechanical load mostly.Due to the device space of manual simulation's erosion environment all smaller (as carbonization case, salt fog cabinet etc.), add the above loader specifically long-pending large, floor area is wide, and after loading, move or adjust the factors such as inconvenience, causing being difficult to when carrying out erosion environment simulation test, concrete component being loaded for a long time.In addition, when carrying out the concrete flexural property contrast test of different mixture ratio and structure requirement, be difficult to accomplish that two independent concrete component stressing conditions reach highly consistent, test cannot be carried out.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of intersecting parallels test concrete component, can obtain long-term constant load; Under identical erosion environment and loading condition, to upper and lower two parts of concrete component of different mixture ratio and structure requirement, flexural property and Erosion Law carry out contrast test.
To achieve these goals, the technical solution used in the present invention is: a kind of intersecting parallels test concrete component, comprise top beam and lower beam, top beam and lower beam are strip, at the place of keeping to the side, two ends of top beam, lower beam length direction, position symmetry is offered porose, the hole that screw rod is offered through top beam, lower beam two ends, and at the two ends of screw rod mounting nuts, top beam and lower beam are linked together, between top beam and lower beam, clamping a cushion block, cushion block is positioned at the center of top beam and lower beam.
Further, also comprise telescopic power sensor, telescopic power sensor setting is on the screw rod between top beam and lower beam.
Further, between nut and top beam, lower beam, pad is set.
Further, cushion block can be spheroid, also can the side's of being body.
Further, cushion block and top beam or lower beam bond together.
The invention has the beneficial effects as follows: loading force is provided by nut, can facilitate and the long-term constant certain load of maintenance, pass through setting nut, can increase the suffered loading force of top beam and lower beam, because cushion block is between top beam and lower beam, under the effect of loading force, top beam and place, lower beam two ends there will be distortion, and the deflection of top beam and lower beam is identical, so, under identical erosion environment and loading condition, can be on the concrete component of different mixture ratio and structure requirement, lower two parts, be that top beam and lower beam flexural property and Erosion Law carry out contrast test.

In figure: 1, screw rod, 2, nut, 3, pad, 4, power sensor, 5, top beam, 6, lower beam, 7, cushion block.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1 to Figure 3, this intersecting parallels test concrete component, comprise top beam 5 and lower beam 6, top beam 5 and lower beam 6 are strip, at top beam 5, the place of keeping to the side, the two ends position symmetry of lower beam 6 length directions is offered porose, top beam 5, in lower beam 6, the hole heart in two of every side holes screw rod 1 on same axis passes top beam 5, the hole that lower beam 6 two ends are offered, and at the two ends of screw rod 1 mounting nuts 2, top beam 5 and lower beam 6 are linked together, between top beam 5 and lower beam 6, clamping a cushion block 7, cushion block 7 is positioned at the center of top beam 5 and lower beam 6, when experiment needs loading force, by answering torque wrench rotating nut 2, now, because cushion block 7 is in the middle of top beam 5 and lower beam 6, top beam 5 and the lower beam 6 of cushion block 7 left and right both directions are all subject to identical Moment, by the present invention, the concrete component requiring at different mixture ratio and structure is under load and erosion environment same case, can make two independently force-summing element be that top beam 5 is consistent with lower beam 6 stressing conditions, thereby while carrying out flexural property contrast test.
For the control to loading force size effectively, also comprise telescopic power sensor 4, telescopic power sensor 4 is arranged on the screw rod 1 between top beam 5 and lower beam 6, telescopic power sensor 4 is connected with vibratory string frequency recorder, by vibratory string frequency recorder, record the reading of telescopic power sensor 4, can to the size loading, control easily.
Lifting surface area while loading in order to increase plays the effect of protection top beam 5 and lower beam 6 simultaneously, between nut 2 and top beam 5, lower beam 6, pad 3 is set.As required, cushion block 7 can be arranged to spheroid, also can the side's of being arranged to body.
Under trystate, cushion block 7 is clamped by top beam 5 and lower beam 6, can be from not coming off between the two, if under non-test state, 6 pairs of cushion blocks 7 of top beam 5 and lower beam do not add the power of holding, and cushion block 7 likely can come off from top beam 5 and 6 of lower beam, generation for fear of this situation, cushion block 7 bonds together with top beam 5 or lower beam 6, even if 6 pairs of cushion blocks 7 of top beam 5 and lower beam do not add the power of holding, cushion block 7 can not come off from top beam 5 and 6 of lower beam yet.
