Embodiment Construction

[0039] The following is attached Figure 2-7 The application is described in further detail.

[0040] When carrying out the static test, at first a hydraulic jack is placed on the top wall of the test pile, and then a main beam 9 will be horizontally erected through the concrete block directly above the jack, and the upper end of the jack is fitted against the bottom wall of the main beam 9, Then eight secondary beams 91 are erected above the main beam 9, and the eight secondary beams 91 are parallel to each other and are all attached to the top wall of the main beam 9. On the top wall of the secondary beam 91, a certain number of concrete counterweights are stacked to complete the process. Counterweight, then connect an oil pump to the jack, start the oil pump to drive the jack to work, and the jack applies pressure to the test pile step by step for static test.

[0041] The embodiment of the present application discloses a static load testing device for concrete beams, refe...

Abstract

The invention relates to concrete beam static load detection equipment, which comprises a mounting plate, the mounting plate is connected with a main beam, the mounting plate is provided with a measuring device which synchronously settles with an engineering pile, the mounting plate is provided with an oil cylinder, a piston rod of the oil cylinder clamps a marking pen through a first clamping piece, the oil cylinder is connected with an oil pump through an electromagnetic valve, and the electromagnetic valve is connected with a computer, when the piston rod of the oil cylinder extends out, the marking pen abuts against the measuring device. The measuring device is connected with the engineering test pile so that the measuring device and the engineering test pile can synchronously settle, the computer controls the electromagnetic valve to start the oil cylinder at fixed time, and the oil cylinder and the marking pen are used for carrying out fixed-time marking on the measuring device, a worker can calculate the settling velocity of each time period by combining the distance between the mark points with the timing duration, and the oil cylinder is controlled by the electromagnetic valve to carry out timing recording, so that the recording of the settling velocity is not easy to have errors, and the precision of a measurement result is improved.

Description

technical field [0001] The present application relates to the field of static load testing equipment, in particular to a static load testing equipment for concrete beams. Background technique [0002] The static load test is to apply vertical pressure or tensile force step by step on the top of the engineering pile, by observing the settlement and rising displacement of the top of the pile under the action of tension or pressure over time, and then determine the axial compressive or tensile force of the single pile through calculation. Test method for tensile strength. [0003] refer to figure 1 , the common test equipment for static load test includes eight secondary beams and a main beam. A hydraulic jack is placed on the top wall of the test pile, and then the main beam is horizontally erected above the jack through the concrete block so that the upper end of the jack is tight. The bottom wall of the main beam, eight secondary beams are erected above the main beam throu...
