Problems solved by technology

Generally speaking, manual arc welders are migrant workers. Therefore, it is inevitable that the quality of manual arc welding process is poor. thus affecting the measurement accuracy
[0004] In addition, when welding, a large amount of heat will be generated, which may damage or change the test components of the strain gauge. For example, in actual work engineering, the heat can damage the strain gauge or reduce the sensitivity, which will lead to a decrease in the test effect or even burn out components, causing the test original to be useless

Embodiment Construction

[0020] refer to figure 1 The present invention will be further described.

[0021] like figure 1 Shown: a new steel bar stress gauge for steel pipe piles and its installation method, the stress gauge 3 is provided with a stress gauge test element 31, including the connecting rod 2 brazed with the steel pipe pile 1, the connecting rod 2 A stress gauge 3 is provided, and two asbestos heat insulation layers 4 are arranged on the connecting rod 2, and the two asbestos heat insulation layers 4 are respectively located on both sides of the stress gauge 3.

[0022] The asbestos heat insulation layer 4 on both sides is used to block the heat generated during welding, effectively preventing the heat from being transmitted to the stress gauge 3 and causing damage to the stress gauge 3 .

[0023] Further, both ends of the connecting rod 2 are provided with welding scales 5 , and the distance from both ends of the connecting rod 2 to the nearest welding scale 5 is the same.

[0024] Th...

Abstract

The invention relates to the technical field of construction engineering and relates to a novel steel bar stress meter for a steel pipe pile and a mounting method thereof. A stress meter test component is arranged in the stress meter, the stress meter includes a connecting rod in brazed connection with the steel pipe pile, the connecting rod is provided with the stress meter and provided with twoasbestos heat insulation layers, and the two asbestos heat insulation layers are located on the two sides of the stress meter respectively. The two ends of the connecting rod have welding scales, andthe distances between the two ends of the connecting rod and the nearest welding scale are the same. The novel steel bar stress meter is simple in structure and high in practicality.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a novel steel bar stress gauge for steel pipe piles and an installation method thereof. Background technique [0002] Steel bar stress gauges can be buried inside reinforced concrete and other structures for a long time. Therefore, in field tests, steel bar stress gauges can be welded to steel bars or steel pipe piles to measure the stress of steel bars or steel pipe piles. When the force is applied, the deformation will follow, which will drive the steel bar stress gauge welded on the steel pipe pile to deform, change the frequency of the steel bar stress gauge, and then measure the frequency through the measuring and reading instrument, and convert it into the corresponding stress. [0003] However, steel stress gauges were welded to steel or steel pipe piles by manual arc welding in field tests. Generally speaking, manual arc welders are migrant workers. The...
