Description

Technical Field

[0001] This utility model relates to the field of building curtain wall technology, and in particular to a portable self-balancing concrete compressive strength testing device. Background Technology

[0002] The strength of the main concrete structure is a key indicator of its safety. Concrete test blocks are typically made during concrete pouring, cured under different conditions, and then subjected to compressive strength tests to analyze the concrete strength of the main structure. The timeliness and accuracy of these tests are closely related to structural safety. In current construction practice, concrete test blocks need to be sent to specialized laboratories for compressive strength testing, which is costly. Commonly used laboratory compressive strength testing equipment includes hydraulic testing machines, which are large in size and require significant installation space and maintenance.

[0003] In practical engineering, laboratory concrete compressive strength testing presses often employ large-range hydraulic types. This requires a large equipment area, and the laboratory is typically far from the site. Test blocks are usually transported in several batches simultaneously, significantly reducing the timeliness of the test. Furthermore, test blocks are highly susceptible to damage during transport, affecting their integrity and the reliability of experimental data. Large-scale projects require an extremely large number of test blocks, and to improve efficiency, conventional concrete test block testing has a long cycle and low frequency, which is detrimental to on-site quality control.

Screw rods are fixed at the four corners of the base. Two connecting rods are arranged in parallel, with their ends respectively sleeved on the two screw rods and screwed to them. The upper pressure beam is located between the two connecting rods, with its ends respectively fixedly connected to the two connecting rods. The pressurizing mechanism is fixed under the upper pressure beam.

[0007] Furthermore, the pressurizing mechanism includes an ear plate, an inverted jack, a pressure plate, a hydraulic gauge, and a hydraulic pump. The ear plate is welded and fixed to the bottom of the inverted jack. A first bolt hole is provided on the bottom surface of the upper pressure beam, and a second bolt hole is provided on the ear plate. The pressure plate is welded and fixed to the anti-slip cap of the inverted jack. The ear plate and the upper pressure beam are fixedly connected by bolts passing through the first bolt hole and the second bolt hole. The pressure plate is in direct contact with the concrete test block, which is placed on the base plate. The inverted jack is a hydraulic jack. The hydraulic gauge is connected to the hydraulic jack circuit, and the hydraulic pump is connected to the hydraulic jack oil circuit.

[0008] Furthermore, the pressure plate is made of steel plate with a diameter of 200-230mm and a thickness of 10mm.

[0009] Furthermore, the base includes multiple square steel bars, each of which has two symmetrically arranged bolt through holes. The bolt through holes on the multiple square steel bars are arranged in parallel and aligned. Bolts pass through the aligned bolt through holes to fix the multiple square steel bars into a base. Four threaded rods are symmetrically fixed to the ends of the two square steel bars on both sides. Two threaded rods at the aligned end positions of the two square steel bars on both sides pass through the ends of a connecting rod and are screwed to the connecting rod.
