Description

[Technical Field]

[0001] The present invention relates to a foundation reinforcing bar arrangement image processing system. [Background technology]

[0002] The foundation structure of a reinforced concrete building is made up of steel bars and concrete working together to support it. Therefore, if the steel bars are not placed according to the design, the strength and durability of the building may be compromised. Reinforcement inspections are carried out to check whether the rebars are correctly positioned according to the design drawings.

[0003] Reinforcement inspection is an inspection that is always carried out before pouring concrete, and involves confirming and reporting that the type, thickness, and number of reinforcing bars are as per the design drawings, that the placement of the reinforcing bars is as per the design drawings, that the joints between the reinforcing bars are properly processed, and that the cover thickness of the reinforcing bars is sufficient. The rebar cover thickness is the distance between the rebar and the concrete surface. If the rebar cover thickness is sufficient, the rebar will be protected by the concrete and the rebar itself will be prevented from rusting or corroding, so it is necessary to check the numerical value of the rebar cover thickness.

[0004] Reinforcement inspections are carried out by specialized inspectors. Inspectors use tools such as tape measures, levels, laser pointers, and cameras to measure and photograph the position and dimensions of the rebar. They also visually check the condition of the rebar. By attaching colored magnets to each type of rebar, they create photographic documentation of the rebar placement, type, and rebar cover thickness, which they then submit as a report. Reinforcement inspection is an important step to ensure the safety of buildings, and if any problems are found during the inspection, they must be corrected before the concrete is poured.

[0005] When inspecting rebar arrangement, in the case of large foundations with complex rebar structures, the above-mentioned identification method using color magnets is problematic as it is sometimes impossible to attach color magnets to the rebars at the back. Also, after taking photographs for the rebar arrangement inspection, the color magnets must be removed, but when doing so, they may fall into the foundation concrete, making them difficult to retrieve. No rational method has been developed to solve this problem of creating reinforcement inspection data.

[0006] In the above technical fields, Patent Document 1 discloses a technology relating to a foundation reinforcing bar structure for constructing a foundation for a corner of a reinforced concrete structure using reinforcing bar units. Patent Document 2 discloses a technology relating to a system and program for calculating the amount of reinforcement in reinforced concrete. Patent Document 3 discloses a technology relating to a cover thickness measurement method and cover thickness measurement system for measuring the concrete cover thickness of an underground structure. However, there is no technology or system that can create and process images of steel frame reinforcement arrangement information required for creating the above-mentioned reinforcement inspection report.

[0008] Steel bar arrangement inspections are carried out to examine the type and arrangement of concrete and steel bars that make up the foundation of a building, and to determine whether the foundation will remain safe in the future.It is desirable for any problems with reinforcement to be identified at the construction site. However, the process of conducting reinforcement inspections at the construction site and having the client check the reinforcement inspection images could delay corrective work if defects are found, potentially affecting the construction schedule. For these reasons, there is a need to reduce the time required for rebar inspections and to identify problems immediately.

[0009] The object of the present invention is to provide technology for a foundation rebar arrangement image processing system using an application on a mobile device such as a smartphone or tablet in order to solve the above-mentioned problems. [Means for solving the problem]

[0010] The foundation rebar arrangement image processing is operated by a system equipped with two functions: a method for taking and processing rebar arrangement images as an application on a mobile device, and a web service that converts already taken rebar arrangement images into images. These two functions can be implemented as separate systems, or as a mobile application that combines both functions. [Effects of the Invention]

[0011] According to the present invention, it is possible to provide a foundation rebar arrangement image processing system and method that can efficiently process and generate rebar arrangement inspection images at a construction site. [Brief explanation of the drawings]
