Abstract

The invention discloses a portable rapid testing device for strength of a concrete test block. The portable rapid testing device comprises a testing jig and a torsion gun. The torsion gun comprises a torsion gun carrier and a motor. The testing jig comprises a test block bearing platform and a power transmission frame. The power transmission frame comprises an installation plate and a transmission gear set which is placed on the installation plate. The power output end of the motor is linked with the transmission gear set through a torsion bar. A torsion gun control switch is connected in the electrification circuit of the motor in series. Moreover, the motor is provided with a displacement converter which can convert the rotating turns of the motor into a vertical displacement value. A pressure sensor is installed on the bearing platform. The displacement converter and the pressure sensor are respectively and correspondingly provided with a power supply connecting line and a signal transmission line. Therefore, the portable rapid testing device for the strength of the concrete test block has the advantages that the volume is small, the device is convenient and portable, the device can be used for rapidly testing the strength of the concrete test block in the construction field and the transportation of the concrete test block can be avoided; and moreover, the device can also be used for indoor testing, the use time of an indoor press is saved and the implementation of other tests is facilitated.

Description

technical field [0001] The invention relates to a concrete test block strength testing device, which can be used for rapid testing of the concrete test block strength at the concrete pouring construction site. Background technique [0002] Concrete is one of the main materials used in modern engineering structures. According to relevant regulations, the strength grade of concrete should be divided by the standard value of concrete cube compressive strength, and a cube of 150mm×150mm×150mm is used as the standard size test piece of concrete compressive strength in my country. The results of test pieces of non-standard size should be multiplied by the conversion factor and converted into standard cube strength. For the concrete axial compressive strength, it is determined according to the axial compressive strength of the prism. In my country, a prism of 150mm×150mm×300mm is used as the standard size test piece for the axial compressive strength, and the results of the non-st...
