Description

Technical Field

[0001] The utility model relates to the technical field of concrete carbonization detection, in particular to a carbonization detection hole-forming device which is easy to operate. Background Art

[0002] Concrete carbonization is an important factor affecting the compressive strength of concrete structures. The carbonization depth value is generally combined with the rebound value to infer the compressive strength of concrete components. Concrete carbonization is a type of chemical corrosion suffered by concrete. When CO2 gas in the air penetrates into the concrete, it reacts chemically with its alkaline substances to produce carbonates and water, and the process of reducing the alkalinity of the concrete is called concrete carbonization.

[0003] A search revealed that in the prior art, an authorized patent with announcement number CN218034816U discloses a hole-forming device for stable control of on-site carbonization depth detection, which relates to the technical field of concrete carbonization detection. The device includes a lower positioning plate with a circle of lower positioning holes evenly arranged around the center of the lower positioning plate; an upper positioning plate parallel to the lower positioning plate with a circle of upper positioning holes evenly arranged around the center of the upper positioning plate, the center distance of the upper positioning holes being greater than the center distance of the lower positioning holes; a distance assembly connected between the upper and lower positioning plates for fixing their relative positions; and a needle with a pointed end for passing through the upper and lower positioning holes and inserting into the concrete to be tested. This application has the effect of reducing the contamination of concrete between different layers and improving the stability of the test results.

[0004] However, the above technical solution still has the following shortcomings when used in practice: the upper positioning plate and the lower positioning plate of the above device are movably set, and the upper positioning plate cannot be locked, resulting in that when the fiber needle is hammered, the fiber needle may accidentally hit the positioning plate, causing the upper positioning plate to slide, thereby moving the fiber needle that has been hammered in, causing the inserted fiber needle to loosen, affecting subsequent hole forming. In this regard, we have proposed an easy-to-operate carbonization detection hole-forming device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide a carbonization detection and pore-forming device that is easy to operate, so as to solve the problems raised in the above-mentioned background technology.

[0007] The locking plate is fixedly secured to the top of the mounting plate and has a plurality of slots for locking the mounting plate, the slots being adapted to lock the mounting plate and the locking plate to lock the mounting plate.

[0008] Preferably, three annular equidistant limiting cylinders are fixedly welded on the top wall of the lower positioning plate, and a slide groove is provided on the limiting cylinder. Three annular equidistant limiting columns are fixedly welded on the bottom wall of the upper positioning plate, and the three limiting columns are respectively slidably connected in the slide grooves of the three limiting cylinders.

[0009] Preferably, a mounting post is fixedly welded to the top end of the connecting rod, two mounting rods are fixedly welded to the top end of the mounting post, and handles are fixedly welded to the two mounting rods.

[0014] 2. The pedal provided in the present invention can be used by the staff to step on the pedal with both feet to fix the lower positioning plate, so that the hole-making device can be completed by one person when it is convenient to step on and fix it, providing convenience of use.
