Abstract
The utility model belongs to the technical field of the pitch experimental facilities of modifying, particularly, involve a concrete punching press impact testing device. It includes plain plate base, a location section of thick bamboo, stereoplasm steel ball and square steel hammer, the plain plate base is the square for hold the concrete, a location section of thick bamboo is supported by the support on each side, be located the concrete directly over, its axis and plain plate base center are on same straight line, the stereoplasm steel ball is put in concrete center top, square steel hammer can pass a location section of thick bamboo, and its axis and stereoplasm steel ball center are on same straight line. Compared with the prior art, concrete punching press impact testing device satisfies national standard, and is easy and simple to handle, and in the process of the test, a location section of thick bamboo can retrain square steel hammer whereabouts gesture, prevents the experimental error that manual operation results in the in -process upset of square steel hammer whereabouts, skew stereoplasm steel ball central line to lead to the fact in the experimentation, improves the accuracy nature of test result.
Description
Technical field
The utility model belongs to asphalt modification technical field of experiment equipment, specifically, relates to a kind of concrete punching press impact test apparatus.
Background technology
The height of agent on crack resistance of concrete punching press impact property is the importance evaluating concrete dynamic performance.In airfield runway, highway pavement, bridge floor or even anti-impact, antiknock, earthquake-resistant modern safeguard structure engineering, concrete anti-impact pressure impact property is had higher requirement.Current China tests agent on crack resistance of concrete punching press impact property according to appendix C in GB/T21120-2007 " cement concrete and mortar synthon ", use experimental provision by plain plate base in this standard, hardened steel ball, square steel hammer composition, owing to adopting manual dropping hammer in experimenter's operating process, square steel hammer is unavoidably caused to produce upset in dropping process, depart from hardened steel ball center line, thus cause experimental error, affect the accuracy of test data, to related scientific research unit, the experiment testing of production unit and unit in charge of construction brings inconvenience.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides the little concrete punching press impact test apparatus of a kind of experimental error.
A kind of concrete punching press impact test apparatus described in the utility model, described test unit comprises plain plate base 1, positioning tube 2, hardened steel ball 3 and square steel hammer 4; Described plain plate base 1 is square, for holding concrete; Described positioning tube 2 is supported by the support 5 on each side, to be positioned at directly over concrete its axis and plain plate base 1 center on the same line; Described hardened steel ball 3 is placed on concrete overcentre; Described square steel hammer 4 can pass positioning tube 2, and its axis and hardened steel ball 3 center are on the same line.
A kind of concrete punching press impact test apparatus described in the utility model, described plain plate base 1 length, width and height are of a size of 200mm*200mm*10mm.
A kind of concrete punching press impact test apparatus described in the utility model, it is 10mm that described plain plate base 1 Ge Bian center is provided with a diameter, is highly the spacing steel bolt 6 of 64mm.
A kind of concrete punching press impact test apparatus described in the utility model, described spacing steel bolt 6 is apart from plain plate base 1 center 81mm.
