Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar engineering testing instruments, and in particular relates to a seawater anti-corrosion steel bar meter. Background Art

[0002] Seawater corrosion-resistant steel bar meters are mainly used to measure the tensile force of steel bars in concrete structures. They can also be connected in series to measure the stress distribution of steel anchors in tunnels and underground structures. The smallest steel bar stress sensor can be connected side by side next to steel bars of all sizes to measure the strain of the steel bars. It is used to test the strain of clay walls, precast piles, caissons, bridge piers, tunnels, etc.

[0003] The traditional rebar gauge is mainly composed of a load-bearing body and a micro strain gauge. In order to fix the micro strain gauge on the load-bearing body, it is generally necessary to set a string clamp to first clamp the two ends of the steel string in the micro strain gauge, and then screw the string clamp to the fixing seat, and the fixing seat is fixed to the load-bearing body by screwing or other methods. Since installation accessories such as the string clamp, steel string, and fixing seat are all arranged inside the load-bearing body.

[0004] In addition, the Chinese patent announcement number is CN218724899U, and the name of the invention is a seawater corrosion-resistant steel bar gauge. The seawater corrosion-resistant steel bar gauge includes a force-bearing body, a fixed box arranged in the force-bearing body, and a strain gauge penetrated through the fixed box. The strain gauge includes an elastic steel string, an outer protective tube sleeved on the elastic steel string, and clamping parts arranged at both ends of the elastic steel string. The clamping parts are clamped at both ends of the outer protective tube. The outer protective tube passes through the fixed box and any clamping parts are arranged on both sides of the fixed box. The two ends of the fixed box are poured with potting glue that imitates the inside of the force-bearing body through a mold, and any clamping part is arranged in the potting glue.

For this reason, we propose a seawater corrosion-resistant steel bar meter. Utility Model Content
