Description
Technical field
The utility model relates to a kind of cubic compressive strength specimen molding device, particularly a kind of extrusion type flexible concrete compressive strength test specimen molding device.
Background technology
The intensity of extrusion type flexible concrete is lower, belong to dry concrete, can not adopt the mode shaping test piece of the secret room that vibrates, according to material behavior and construction characteristic, test method adopts the method moulding of hydrostatic profile, during moulding according to the field measurement dry density, moisture content, after obtaining the required quality of mixing and stirring material of each test specimen by the die trial volume calculations, take by weighing again and mix and stir material, the mix that weighs up is poured in the die trial, adopt pressue devices such as forcing press to carry out hydrostatic profile then, because concrete is a loose structure before the compacting, volume is greater than the die trial volume, and the specimen molding time of adopting conventional concrete cube die trial to obtain is long, of poor quality, stress during shaping test piece can't with the site operation state consistency.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of extrusion type flexible concrete compressive strength test specimen molding device simple in structure, easy to use, saved the specimen molding time, guaranteed the specimen molding quality, stress when having simulated specimen molding effectively makes itself and site operation state basically identical, whole forming process can be finished indoor, and is easy to use.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of extrusion type flexible concrete compressive strength test specimen molding device, comprise die trial, the die trial top is with cover die, the interior sectional dimension of cover die is consistent with the interior sectional dimension of die trial, pressing plate is positioned in the cover die, and the size of pressing plate lower surface is consistent with sectional dimension in the cover die, and the pressing plate top is placed with the biography column.
The longitudinal section of pressing plate is trapezoidal, and the upper surface of pressing plate is provided with and passes the groove that column matches.
The thickness of pressing plate is identical with the height of height sum that passes column and cover die.
Have screw on the upper surface of pressing plate, movable handle is connected with pressing plate by screw.
The extrusion type flexible concrete compressive strength test specimen molding device that the utility model provides, owing on conventional concrete cube die trial basis, increase cover die, pressing plate and force-transmitting pole, guaranteed that test specimen mix in the static pressure process is not scattered around die trial, avoided the loss of test specimen quality, by force-transmitting pole and pressing plate pressure is evenly distributed on the mix, guaranteed the specimen molding quality, saved the specimen molding time, stress when having simulated specimen molding effectively makes itself and site operation state basically identical, whole forming process can be finished indoor, and is easy to use; The height of biography column is identical with the height of the thickness sum of pressing plate and cover die, can make test specimen in the static pressure process, and the height of test specimen is just in time consistent with the height of die trial, has further guaranteed Forming Quality, has reduced useless part probability; The design of movable handle has made things convenient for laying and dismantling of pressing plate on the pressing plate.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
