Cylindrical concrete sample core multipoint strength detection device for constructional engineering

Abstract

The invention relates to the technical field of construction equipment, and discloses a cylindrical concrete sample core multipoint strength detection device for constructional engineering. The devicecomprises a fixed base, wherein a limiting groove is formed in the middle part of the upper end of the fixed base, limiting blocks are slidably arranged in the limiting groove, a rotating shaft is mounted between the middle parts of the limiting blocks, a left-hand thread is formed in the middle part of the left side of the rotating shaft, a right-hand thread is formed in the middle part of the right side of the rotating shaft, moving columns are installed at the upper end of the limiting blocks, rotary shafts are installed in the middles of the moving columns through bearings, rotating frames are installed at one ends of the inner sides of the rotary shafts, a supporting column is installed in the middle of the upper end of the fixed base, a supporting ring is installed at the top end ofthe supporting column, hydraulic cylinders are installed on both sides of the upper end of the fixed base, and hydraulic shafts are installed at the top ends of the hydraulic cylinders. According tothe device, up-and-down movement of an extrusion block is achieved, the extrusion effect on a concrete sample core is ensured, meanwhile, through mutual cooperation of the arranged limiting blocks andclamping frames, the clamping and fixing effect on the cylindrical concrete sample core is achieved, and angle rotation can also be achieved.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a multi-point strength detection device for cylindrical concrete sample cores used in construction engineering. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics...

[0004] Chinese patent (notification number: CN210639017U) discloses a construction engineering concrete strength detection device, including a base, a detection box, a driving device, a first detection device and a second detection device; the upper end of the base is provided with a detection box, and the detection The upper end of the box is provided with a drive device, the inner left end of the detection box is provided with a first detection device, and the inner right side of the detection box is provided with a second detection device; the drive device includes a mounting box, a drive motor, a lifting rod and Lifting plate; the middle position of the upper end of the detection box is provided with a mounting box, and the inner upper end of the mounting box is provided with a mounting plate, and both sides of the lower end of the mounting plate are provided with mounting rods, although the device can be realized to a certain extent. Effective detection of concrete strength, but in actual operation, it is necessary to install and replace concrete samples multiple times during pressure cavity detection, which is very inefficient and cannot meet the needs of multi-point strength detection at one time. Therefore, further improvement is needed
