Description

  The present invention relates to a maintenance system and a maintenance management method for a so-called ALC outer wall in which an outer wall of a building is constructed with an ALC panel. More specifically, the present invention relates to a system and a management method for systematically maintaining an ALC panel including a newly constructed or existing building outer wall and an ALC outer wall including joint sealing and finish coating.

  Conventionally, for example, in newly constructed buildings, warehouses, factories, stores, etc., which have ALC on the outer wall of a steel structure building, etc., regular inspections have been performed according to the durability of joint sealing and finishing paint. There was no planned maintenance (deterioration diagnosis and repair / renovation work) including ALC of materials. In addition, when an existing building with ALC on the outer wall deteriorated over time, maintenance work on the outer wall was carried out, but no planned maintenance of ALC, sealing, or painting was carried out after the work.

  For example, the present applicant has previously proposed the deterioration diagnosis of ALC panels and the determination of repair / repair methods as shown in Patent Document 1 below. According to this, it is possible to properly diagnose the deterioration status of the ALC panel and execute a repair / repair method suitable for it, but even if only the ALC panel is repaired and repaired unplanned, the performance as an outer wall will be extended for a long time. It cannot be kept stable. For example, if the sealing material or coating film is left in a deteriorated state, the ALC deterioration of the base material is accelerated, thereby shortening the life of the outer wall or causing an abnormality of the outer wall only when a situation such as water leakage occurs. Often found.

JP 2003-35657 A

  The present invention has been proposed in view of the above-mentioned problems, and the object of the present invention is to leave the sealing material and finishing coating film of the ALC outer wall in a deteriorated state, thereby causing the aging of the base material ALC. An object of the present invention is to provide a maintenance system and a maintenance management method for an ALC-made outer wall that can satisfactorily prevent deterioration of the outer wall from accelerating deterioration.

  A maintenance system for an ALC external wall according to the present invention is a system for attaching an ALC panel to the outer surface of a building, performing joint sealing between adjacent panels, and performing maintenance on the ALC external wall having a painted finish on the panel surface. A management server to which a management terminal is connected, and a computer system to which a customer terminal is connected to the management server through a communication network. The management server includes information on the building, ALC, sealing, and painting. Information database, external wall maintenance plan, maintenance implementation information, etc., a means for registering various information in the matter database, a means for automatically creating a maintenance plan, a maintenance plan creation time, Maintenance plan at each end before the maintenance date And means for displaying, characterized in that a degradation diagnostic system for determination of repair repair method and the degradation diagnosis of the ALC Zogaiheki.

  In addition, the maintenance management method for an ALC external wall according to the present invention is as follows. The person in charge of a newly constructed ALC external wall and a building that has undergone deterioration diagnosis or repair / renovation on a new or existing ALC external wall from the management terminal After registering ALC information, ALC / sealing / painting information, and maintenance execution information in the project database, the maintenance process for the external wall is automatically created, and the maintenance plan created by the customer is displayed on the customer terminal. The process of making a contract, the process of automatically starting the maintenance plan display program and displaying the maintenance plan on the customer's terminal when the maintenance contract date for the customer who has made the maintenance contract is a predetermined date, and the maintenance plan Maintenance work from a customer who confirmed the contents of Upon receiving an order, the exterior wall is diagnosed for deterioration, a process for determining an appropriate repair / repair method, a process for performing repair / renovation work by the repair / repair method, and maintenance information after completion of the repair / repair work in the project database. And a process of registering. In the present invention, the term “new construction” is not necessarily strictly limited to a new building as a whole. For example, a new construction may be a few years after construction or a part of the building may be extended or renovated.

  According to the maintenance system and the maintenance management method for an ALC external wall according to the present invention configured as described above, an optimum maintenance plan is created based on various information necessary for maintenance, and before the maintenance execution time is reached. Since the customer is always contacted, the sealing material and the coating film are not left in a deteriorated state, so that the aging of the base material ALC is suppressed and the life of the outer wall can be extended. Moreover, since the deterioration state of the base material can be monitored periodically, the possibility of occurrence of damage due to an abnormal situation such as water leakage can be significantly reduced.

  A maintenance system and a maintenance management method for an ALC external wall according to the present invention will be specifically described below based on the embodiments shown in the drawings.

  FIG. 1 shows an example of a computer system that performs maintenance management of an ALC external wall according to the present invention. In FIG. 1, reference numeral 1 denotes a computer management server that manages the maintenance of an ALC external wall. Be placed. A management terminal 2 such as a computer (PC) for a manager is connected to the management server 1, and a customer terminal 3 such as a customer computer (PC) is connected to the management server 1 via a telephone line or the Internet. Or the like via a network N such as

  The management server 1 includes an information processing unit 11 and a storage unit 12. The storage unit 12 stores a case database in which case (building) information and the like are recorded, a case database registration program, a maintenance plan creation program, and a maintenance plan. A display program is provided. Further, the management server 1 is provided with a deterioration diagnosis system that selectively determines a deterioration diagnosis of the ALC panel and a repair / repair method based on the diagnosis result. In this embodiment, the management server 1 conforms to Patent Document 1. A deterioration diagnosis system, which is computer software, is stored.

  Table 1 shows information on the case database stored in the storage unit 12 of the management server 1. The information is broadly divided into three types: project relations, maintenance plans, and maintenance implementation details, the details of which are as shown in Table 1 below.

  Tables 2 (a) to 2 (c) below show ALC, sealing, and paint durability years tables for each project used in the maintenance plan creation program.

  As the ALC material, it is described in the above-mentioned Patent Document 1, and a conventional Sipolex panel manufactured by Sumitomo Metal Mining Sipolex Co., Ltd. and a Sipojoule panel or a dry panel excellent in carbonation resistance are used. On the other hand, the durable years are determined depending on whether the finish coating material is inexpensive, such as resin lysine, and the case where the finish coating material is higher quality than the elastic tile. In this embodiment, the number of years until the ALC deterioration level, which will be described later, reaches 4, is defined as the durable life. As shown in Table 2 (a) above, the low cost finish for general panels is 15 years, and the high quality finish is used. 30 years for products, 30 years for low-priced panels and dry panels, and 50 years for high-quality finishes.

  Sealing materials are classified into polyurethane-based, modified silicon-based, and others as shown in Table 2 (b) above, and the construction staff sets for each material and building with respect to the durable life (standard service life) of the sealing material. Multiply the condition coefficient to determine the durable life. Also, paints are classified into resin lysine, elastic tiles, acrylic film waterproofing materials, fluororesin top coats, and others as shown in Table 2 (c) above. decide.

  For example, in the case of a sealing material, the above-mentioned revised durability years include the standard life of the sealing material, the material coefficient of the adherend, the color and orientation coefficient of the adherend, the adhesion difficulty coefficient, the processing difficulty coefficient, and the construction workmanship. The estimated useful life is calculated by multiplying the coefficient, deterioration external force coefficient, maintenance factor, etc., and the durable life is determined by considering the estimated useful life. The same applies to the durability of the paint. In addition, the above review durability years may be determined in units of a predetermined number of years, and in this embodiment, the review durability years are determined in units of 5 years. In other words, the review durability is set to be a multiple of 5.

  Table 3 below shows an example of an ALC deterioration level table for classifying the deterioration state of ALC.

  In this example, the degradation state of ALC was classified into five levels of levels 1 to 5 according to the degree of carbonation accompanying the progress of carbonation of ALC as in the requirement described in Patent Document 1. That is, when the carbonation degree is 0 to 20%, the deterioration level is 1, when the carbonation degree is 20 to 30%, the deterioration level is 2, and when the carbonation degree is 30 to 40%, the deterioration level is 3, and the carbonation degree is Is 40 to 50%, the degradation level is 4, and when the carbonation degree is 50% or more, the degradation level is 5. The degree of carbonation depends on the total calcium oxide content (mass%) to be measured and the carbon dioxide gas content (mass%) corresponding to the weight loss at 600 to 900 ° C. {(carbon dioxide gas content) × 56 / 44} / (total calcium oxide content) × 100.

  Table 4 below shows the combination of the paint, sealant and ALC durability that will be used as the basis for automatically creating a maintenance plan using the maintenance plan creation program. (1) is for new construction and (2) is for ALC repair.・ This is a case of creating a maintenance plan after the renovation work.

  In the case of the new construction shown in Table 4 (1), the durable years of the paint, sealing material, and ALC used are determined by the durable years table shown in Table 2, and a maintenance plan is automatically created based on the durable years table. The plan No. in the table is a maintenance plan number shown as an example in Table 5 to be described later.

  In addition, if a newly diagnosed ALC exterior wall is repaired and repaired according to the maintenance plan and ALC is repaired / refurbished, or if an existing ALC exterior wall is degraded and repaired / refurbished, based on (2) in Table 4 above Maintenance plan after ALC repair / renovation work is automatically created. In this case, the durable years of the paint and sealant used are determined by the durable years table shown in Table 2, and the durable years of ALC are determined according to the deterioration stage of the ALC deterioration level table shown in Table 3. And create a maintenance plan automatically.

  Table 5 below shows an example of a maintenance plan in the case of (1) new construction and (2) repair / renovation of ALC.

  This example is based on the premise that the same material or durable life paint and sealing material as in the new construction will continue to be used for maintenance, as described above, every 5 years depending on the durable life of ALC, sealing, and painting. It shows the basic maintenance plan to perform.

  Plan No. 1 in Table 5 (1) shows a maintenance plan in the case where the durability of the paint and the sealing material is 5 years and the durability of the ALC material is 15 years in Table 4 (1). Specifically, for example, when maintaining a newly constructed ALC outer wall in which the type of ALC material in Table 2 is a general panel, the sealing material is polyurethane, and the type of paint is resin lysine, the above-mentioned paint and sealing material This is the case when the endurance years are 5 years and the endurance life of the ALC material is 15 years.

  By the way, Plan No.1 in Table 5 above is the paint diagnosis / construction, 5 years, 10 years, and 15 years after the construction, because it is the durable life of the paint. Each year is the endurance of the sealant, so the sealant is replaced. In addition, ALC diagnosis / construction is less than the endurance years of ALC for the 5th and 10th years after construction, so in principle it is maintained and maintained as it is, and 15th year after construction is the endurance for ALC, so it is subject to predetermined deterioration. The plan is to carry out repair and repair work after making a diagnosis. This repair / renovation work is performed based on the result of the deterioration diagnosis described above, and there are cases where a partial repair or repair is required and a case where the entire surface is replaced. The same applies to the plans No. 2 to 4 described later.

  In addition, the plan No. 2 in Table 5 (1) is the same as above, but in Table 4 (1), the durability of the paint is 15 years, the durability of the sealing material is 5 years, and the durability of the ALC material is 30 years. The maintenance plan for the new ALC external wall is shown. The “maintenance sealant coating” in the table is used for diagnosis and construction when the paint is less than the endurance limit year. In principle, the painted part of the panel is maintained as it is, and the sealing part is painted. It represents the work of applying. Other work is the same as the plan No.1.

  On the other hand, when maintenance management is to be continued after repairing or renovating a new or existing ALC exterior wall, specifically, for example, according to the maintenance plan No.1 or No.2, repairing and refurbishing ALC in those final years. When performing maintenance management after performing the maintenance, or performing maintenance management after repairing and renovating the ALC after diagnosing the deterioration of the existing ALC external wall at a desired time, as shown in Table 4 ( A maintenance plan is automatically created based on 2).

  In this case, the durability of the paint and sealant used (reviewed durability) is determined by the durability table shown in Table 2 above, and the durability of ALC is the ALC performed when the ALC was repaired and repaired first. This is determined based on the deterioration diagnosis of the product. Further, in this embodiment, as shown in Table 4 (2), when the ALC deterioration level is 1 to 3, the durable life of the ALC is uniformly 20 years, and the ALC deterioration level is 4 or 5. In this case, the durable life of ALC is uniformly 10 years.

Plan No. 3 and Plan No. 4 in Table 5 (2) show an example of a maintenance plan in the case where maintenance management is continued after repairing or renovating a new or existing ALC external wall. 3, ALC degradation level is any one of 1 to 3 as shown in (2) of Table 4 above, the durability of ALC is 20 years, the durability of paint is 5 years, and the durability of sealant is 10 This is a maintenance plan for the year. Plan No.4 shows that the ALC deterioration level is 4 or 5 as shown in Table 4 (2) above, the ALC durability is 10 years, the paint durability is 15 years, and the sealing material durability is 15 years. This shows the maintenance plan for 5 years.

  In Table 5 (2) above, “maintenance for maintenance management” means that ALC is maintained and maintained as it is, unless there is any particular inconvenience before ALC reaches the endurance life, and partially deteriorated. If there is damage, repair the part. This partial repair may be performed as necessary in the plan No. 1 and the plan No. 2 in Table 5 (1).

  FIG. 2 shows an example of a process for performing a series of management from registration of an ALC external wall project to creation of a maintenance plan, maintenance contract with a customer, maintenance execution guidance, and maintenance using the computer system of FIG. In the following, description will be given in order.

  First, in the new project registration (1) in FIG. 2, the person in charge of the ALC production company, for example, starts the project database registration program for a newly constructed ALC exterior wall or an ALC exterior wall building that has undergone a deterioration diagnosis on an existing building. Then, the building information, ALC / sealing / painting information, past maintenance information, etc. are input from the management terminal 2 and registered in the project database. Then, the maintenance plan creation program of FIG. 1 is automatically started, and a maintenance plan for the ALC outer wall as shown in Table 5 is automatically created.

  The maintenance plan automatically created as described above is stored in the case database, and the maintenance plan display program is automatically activated to the management terminal 2 of the person in charge and the customer terminal 3 of the case. The maintenance plan is displayed. Therefore, the person in charge contacts the customer and makes a maintenance contract with the customer for the matter.

  Next, when a predetermined period before the maintenance execution date (2) in FIG. 2 (for example, 1 to 6 months before, 3 months in the present embodiment), the maintenance plan display program is automatically started and the maintenance plan is in charge. Displayed on the customer terminal 3 corresponding to the management terminal 2 of the user. The person in charge confirming the maintenance plan contacts the customer and explains the details of the maintenance work for the case to the customer. When the maintenance work request from the customer is input from the customer terminal, the case database registration program is automatically started, and the maintenance work order information is stored in the case database.

  Next, when the maintenance day (3) in FIG. 2 is reached, the lightweight foam concrete deterioration diagnosis system is activated and the outer wall deterioration diagnosis is performed to determine a repair / repair method. In this embodiment, the deterioration diagnosis system based on the said patent document 1 evaluates the deterioration condition of an outer wall, determines an appropriate repair and repair method, and implements repair repair work. Specifically, for example, as described in Patent Document 1, finishing repair, sealing repair, U (V) cut mortar filling method, U (V) cut sealing filling method, permeable surface reinforcing agent, foamable resin What is necessary is just to select suitably from a repairing method such as an injection method, a net reinforcement method, a panel surface fiber reinforcement method, a steel material reinforcement method, and a panel replacement method in consideration of deterioration conditions and costs.

  When the repair / repair method is determined as described above, the repair / renovation work is carried out according to the repair / repair method. The determination of the repair / repair method and the repair / repair work may be performed after the results of the deterioration diagnosis, especially when it takes time to determine the measurement result of the degree of carbonization. After the repair / renovation work is completed, the project database registration program is started, and maintenance information such as the details of the performed work is added to the project database. Thereafter, each time the scheduled date described in the maintenance plan approaches, the operations in FIGS. 2 (2) and (3) are repeated, and when all plans are completed, a new maintenance plan is further advanced as shown in FIG. The operation from 1) may be repeated again.

  In the above-described embodiment, the review durable years of the sealing material and paint in Table 2 and the maintenance work years in Table 5 are set on the basis of five years, but those years, the durable years of ALC in Table 4, and others The number of years can be changed as appropriate. Also, the maintenance end years in Table 5 can be changed as appropriate according to the lifetime of the building, the number of years the owner wants to manage, and the like.

  In the above-described embodiment, the maintenance plan is created on the assumption that the same material or the durable material (paint, sealing material, panel) of the new construction is used repeatedly during the maintenance work. The material does not have to be years, and if the durability is different, a maintenance plan may be created in consideration of the durability.

  As described above, according to the maintenance system and the maintenance management method for an ALC external wall according to the present invention, not only the panel but also the sealing material and the coating film are not left in a deteriorated state. And the lifetime of the outer wall can be maximized at a minimum cost. Further, since the deterioration state of the base material can be monitored regularly and systematically, it is possible to satisfactorily prevent the possibility of damage due to an abnormal situation such as water leakage and the deterioration of the durability and life of the building. Furthermore, maintenance management according to the type of building, purpose of use, or owner's needs is possible, and the degree of freedom in selecting a maintenance method and time can be increased.
