Abstract

PROBLEM TO BE SOLVED: To emit plasma to detect a crack, rust and the like by an optical measuring instrument, and to conduct confirmation and execution by an image therein, since a structure in the central city is multistoried in the present and is difficult thereby to observe visually the crack in an outer wall in a level of 50-80 m, in repairing, inspection and the like for the outer wall of a building. SOLUTION: Assembling work for a scaffold board is eliminated in the multistoried building or the like to allow safely the inspection for the outer wall.

Description

Description: BACKGROUND OF THE INVENTION [0001] The present invention relates to mortars for buildings, overpasses, steel towers, tunnels, underground trenches, etc.
The present invention relates to an optical measuring device for measuring and detecting concrete, warek racks, reinforcing bars, steel corrosion, and rust. 2. Description of the Related Art When repairing an inspection building or the like, a scaffold plate is assembled and the outer wall is hit with a hammer on the scaffold plate to check cracks, cracks, etc., and to perform repair work. [Problems to be Solved by the Invention] With regard to the conventional inspection and measuring method, work with a hammer in hand, riding on a scaffold plate, and hitting a wall with a hammer, as seen with a telescope or human eyes. Is very dangerous. Currently, buildings built in the city center are being multi-storey,
It is impossible to assemble and inspect scaffolding boards in the m-th building. [Means for solving the problems] When buildings, buildings, etc. become high-rise and mortar or concrete ages and cracks appear, mortar falls It is dangerous and is a problem in the maintenance of the building. [Embodiment of the Invention] The outer walls of buildings, cracks, under bridges, steel bars, steel frames, mortar drops, joints of high-voltage wires of towers, cracks of guy stones, etc. Using infrared rays, images of falling mortar of outer walls, reinforcing bars, steel frames, mortars, and underground trenches are projected on a graph, and the data is measured, input, and checked, checked, and repaired based on the data. [0006] Using a high-precision, digital, microscope, the outer wall with an optical measuring instrument (crack, crack,
Rust, corrosion) is input to a personal computer, and the data is recorded and confirmed for construction and process. Buildings, towers and underground structures are mortars,
Since it is a structure made using concrete reinforcing bars and steel frames, rusting mortar and concrete corrosion can cause aging and danger. The scaffold was assembled to a high place to detect the aging, corrosion and cracks, and it was very dangerous because I was hanging on a rope and working. In order to solve this problem, inspection using a microscope has made it possible to measure very safely and to places that cannot be seen by the human eye.

[Brief description of the drawings] FIG. 1 is a diagram illustrating a method of measuring a building outer wall. FIG. 2 is a diagram showing a method of measuring an underground trench structure in a tunnel. FIG. 3 is a diagram showing a measurement method under an overpass. FIG. 4 is a diagram showing a method for measuring a tower spar.
