Method of marking construction structures

The present invention is a method for marking a building structure, and more particularly, a method for marking a concrete building structure using Radio Frequency Identification (RFID) technology.

There are various types of materials for construction and construction methods are different. Among all engineering materials, reinforced concrete structures and steel reinforced concrete structures are economical, robust, and durable, and are the main building tools used in the construction industry.

When using reinforced concrete and steel reinforced concrete structures for construction projects, it is necessary to analyze the constituent materials and components of the concrete structures according to the design, planning, construction and other steps in the project to ensure the progress of the project and the structure. safety.

Concrete structures are composed of highly complex and variable materials. Each component and component has its own characteristics, structural safety (strength and toughness) of concrete structures, maintenance and construction convenience after construction. The impact of the importance.

As mentioned above, before and after concrete construction, due to the complex composition of concrete structures, the information on related components is large and varied, and such large and complex concrete structure related materials may cause the following problems or problems:

(1) The information in the process of reinforced concrete and steel reinforced concrete construction, such as the specifications of the components used in the structure, is not easy to store.

(2) Most of the reinforced concrete projects are applied at the site, and the quality inspection (supervised work) of the construction is affected by the construction conditions. It is not easy to verify and check a large number of component materials.

(3) In the on-site application of reinforced concrete construction, the construction will be affected by the site conditions, so the materials used (such as mixed sand and gravel), mixing, pipeline configuration and structural components (such as drainage channels) will often be adapted to local conditions. And to make changes, it needs to be recorded.

(4) The components buried in the reinforced concrete construction during the new construction need to be marked, especially in the positioning of the correct position of the embedded components after completion, the operation is quite cumbersome.

(5) After the reinforced concrete construction is completed for a period of time, its structure is affected by the environment and deteriorates. Therefore, the building must be regularly managed and maintained after completion. The damage of concrete structure damage must be evaluated based on the information of the original building. The extent and location of the building to avoid hazards in advance; in addition, the construction of the building will also affect the stability of the structure due to different external forces, and also depend on the information of the construction of the building to repair, these maintenance and related assessment operations It will become more difficult and cumbersome due to the difficulty in maintaining and managing the information on the building materials.

(6) After the completion of the reinforced concrete construction, if the project is to be built, reconstructed, or repaired, and the original materials are lacking, the subsequent construction process, whether it is the preparation of building materials, the design of new structures, and the old structure The repair of the object may not meet the demand.

At present, the construction industry is responsible for the construction of concrete structures, the preservation of structural components, the production of archives, the transfer of files, and the classification, which are basically the responsibility of the construction contractors. During the construction of public works, the information of the components purchased by the contractor and the records of on-site construction are often kept by the owner, but the documents are kept for a limited time and handover problems. As for the preservation of general civil concrete construction information, except for some information that needs to be reported to the competent authority, other information is less likely to be preserved for a long time. As for the state in which the construction is affected by the environmental effects, it is generally not noticed and recorded.

Observing the current information management methods for concrete construction structures, how to integrate the identity certification and information integration system platform of concrete structures in combination with the development of today's technology is one of the important topics in the construction industry.

On the other hand, in the case of reinforced concrete structures, it is mainly used to appropriately arrange the steel bars to provide structural strength of the structures. In reinforced concrete structures, steel spacers and steel protective layer gaskets are commonly used components. Their function is to limit and fix the position of steel bars in concrete structures in the arrangement of steel bars to avoid coarse aggregates. The rarity and the thickness of the protective layer of the steel. It is common practice to pre-cast concrete into small pieces of concrete of appropriate size, which can then be inserted or suitably secured between the bars or between the bars and other fixtures as a steel spacer or Reinforced protective layer gasket. The advantage of using concrete casting to make steel spacers and steel protective layer gaskets is that the material is the same as the concrete structure and can maintain good mechanical transmission behavior.

Furthermore, radio frequency identification (RFID) technology is currently the subject of highly developed research in the world. Its current major development is logistics control, especially with its uniquely identified features, which can provide efficient item identification and control processes. In terms of this characteristic, the application of radio frequency identification technology in the construction of concrete structures in the industry has a very advantageous vision. Simply put, the introduction of radio frequency identification technology can easily and conveniently save the relevant information of concrete structures, and It can provide such information anytime and anywhere, which can improve the convenience, consistency and integration of the relevant information of concrete structures, which can help the automation, intelligent, digital and sustainable development of the construction industry. .

Known construction techniques also apply to the application of radio frequency identification technology to concrete structures, such as the national invention patent publication No. 200741067 or the Japanese Patent Publication No. 2006-071575, which all directly embed the radio frequency identification tag in the structure. In the concrete, since the radio frequency identification is placed in the space where the concrete is to be poured before the concrete is poured, the pouring of the concrete often causes the RFID tag to be displaced or even damaged, which causes difficulty in identification. It is also possible that the identification of the RFID tag will be affected by the thickness of the concrete after the pouring. In addition, in terms of the structural safety of the concrete structure, the RFID tag is placed in the space where the concrete is to be poured, which easily interferes with the construction of the concrete, or even affects the structural safety.

Based on the foregoing, it is a primary object of the present invention to provide a method of marking a building structure for the application of identity history management and specific location information to a concrete structure in the construction industry.

According to the present invention, the functional radio frequency identification tag component formed by incorporating the radio frequency identification tag into the constituent elements of the concrete structure can protect the radio frequency identification tag from concrete placement in structural safety, concrete placement workability The damage, the RFID tag is free from displacement due to the placement of concrete, and the RF identification tag is free from good factors and functions due to various factors such as the installation location or the thickness of the steel or concrete layer. Therefore, according to a preferred embodiment of the present invention, the RFID tag is combined with the basic components of the concrete structure such as the steel spacer or the steel protective layer gasket to be used in the concrete member application process. The radio frequency identification tag component provides non-destructive information transfer and information detection functions. This eliminates the need to additionally consider the considerations required for the RFID tagged concrete structure in the conventional form. In addition to the original functions of the basic components of the concrete structures in the concrete engineering, the functional RFID tag elements of the present invention can also be constructed by radio frequency identification technology or overflow technology (eliminating the shielding effect). The relevant parameters of the object are stored in the radio frequency identification tag embedded in the basic component of the concrete structure, so that the user can use the RFID reader to sense/read/write/update relevant information for concrete construction.

In particular, the present invention relates to the construction of concrete structures in the concrete structure, the introduction of radio frequency identification technology, so that the relevant information of the concrete structure can be easily obtained and retained, thereby improving the convenience, consistency, and integration of relevant information acquisition. In order to achieve the goal of automation, intelligence, digitalization and sustainable operation of the construction industry.

Furthermore, in addition to providing the function of information acquisition of concrete members, the present invention can also place the functional radio frequency identification tag component at a specific position, such as a pipeline bend (water leakage), a specific location specific pipeline type, and A specific functional wall (such as a shear wall or load-bearing wall), etc., can convey relevant information. By reading the conditions that may occur at that particular location, and in conjunction with on-site incidents to assist in the assessment of the state of the building, the assessment of building safety and the maintenance of building repairs.

Therefore, the functional radio frequency identification tag provided by the present invention has a wide application level. The application introduces the radio frequency identification technology into a chimeric type, and the concrete member has its own identity history invisibly, and can also pass through the present invention. Functional RFID tag components provide instant access to detailed information on concrete structures. In addition, through the integrated development of the radio frequency identification information system of concrete structures, in addition to speeding up the efficiency of on-site staff, the back-end staff can also obtain key information of concrete structures in real time to improve the efficiency and consistency of information integration. Sex.

The functional radio frequency identification tag component of the present invention is composed of a concrete material and a radio frequency identification technology, and is realized by incorporating an RFID tag into a component of a concrete structural element, so when applied to concrete engineering, its influence The degree of construction quality or workability is very low. Therefore, the present invention can be applied to concrete structures such as reinforced concrete structures, and is also applicable to concrete structures such as steel reinforced concrete structures, and such concrete type structures. There is a need to store component information and understand local location information.

Moreover, the trend of contemporary architecture is the development of intelligent architecture.
