Description

  The present invention relates to a construction method capable of easily maintaining a history of periodic building exterior inspection and repair work.

For buildings such as industrialized houses, house builders who have newly constructed them manage their design specifications, design drawings, completion specifications, completion drawings, delivery date, etc. consistently with paper materials and computer data, and appropriate A system is in place to conduct appropriate periodic inspections, renovations, or renovations with appropriate materials at appropriate times.
By the way, at the time of periodic inspection, renovation work, or renovation work, members constituting the building are made according to the state of durability deterioration. At this time, when determining whether to repair or replace, it is necessary to accurately diagnose the current state of building components and determine the remaining durable years. In particular, when replacing parts, there are few cases where the parts at the time of construction are usually available, and substitutes (new parts) with improved functions and performance are used. House manufacturers need to confirm (preliminary verification) whether or not replacement with new members is possible from a technical point of view, such as functions and performance, so that homeowners can use it with confidence and continue to live. . The judgment and pre-verification of whether or not these repairs or replacements should be performed include the specification information of the parts actually installed in the building and the act of confirming the construction time, especially selected at the time of new construction or the previous renovation work. Most important.

However, there are various ways of recording such information, and the design specification information is enormous. Therefore, for example, even if computer data is constructed and managed, it is easy to manage whether or not renovation work is performed, and the timing, etc. It is also conceivable that accurate deterioration diagnosis of the current state of the component members and determination of the remaining durable years are difficult.
In addition, in periodic inspection, renovation work, or renovation work, history information of the contractor and worker is also important. Therefore, it is very troublesome for office work and it is a problem in information management that the house maker brings back these records and the information of updating them from the site and accumulates information transmitted from the traders.

On the other hand, in order to solve the difficulty of managing information as a database on a computer of a company or the like in this way, it is necessary for maintenance at the site by using a member such as a building or housing member with an IC tag disclosed in Patent Document 1. It is possible to leave a lot of information. Patent Document 2 is a computer system of a maintenance program that has been researched and developed by the applicant, and that adjusts and controls the useful lives of the components that make up the building, enabling efficient periodic inspection and repair work. , And such buildings are disclosed.
However, members such as architectural and residential members with IC tags disclosed even using the technology of Patent Document 1 require measures such as waterproofing and moisture proofing under outdoor exposure, and until the next renovation work There is no reliable way to keep track records and history information.

Further, even if the maintenance program of Patent Document 2 is planned, it will not be as planned due to the progress of deterioration, that is, sudden repair work will occur due to natural disasters, human factors, etc. In some cases, when each part and location of the building is not uniform, it may be necessary to review the initial maintenance program such as when building a new building. Therefore, management of whether or not renovation is performed is likely to be complicated, and it is expected that the renovation will deviate from the regular renovation time.

  In view of the above background, the present invention allows a maintenance worker or site manager to easily check the history of design specifications of a building necessary for maintenance without requiring a special technique such as an IC tag. Information recording method that can determine how the contents of maintenance work should be done in the regular inspection of the site in question, more specifically, such information according to the lifetime of building exterior components In order to ensure that subsequent renovation work is performed at an appropriate time even if there is a change in the maintenance program due to a sudden disaster, etc. It provides a construction method that can keep records and histories.

The present invention is as follows.

Here, the “finishing member for renovation work” is a surface finishing member used in roof waterproofing work, roofing work, siding replacement work for outer wall plates, and the like, and is a solid material capable of producing plate-like plates. “Renovation work” is work that involves replacement or repair (repair) of components.
“Renovation work information” refers to the method employed for the renovation, the time of the renovation work, and other information regarding the rehabilitation contractor. For example, a term indicating “specifications / manufacturers”, a term indicating “year of construction”, “month of construction”, “time of renovation work” corresponding to the maintenance program described later, and “design useful life of refinished parts” Etc. It is preferable that the information is divided into symbols as appropriate. These history information is configured as a plate divided into multiple blocks such as “general-purpose blocks” and “variable blocks such as year, month, etc.”. For example, as shown in FIG. To do. In addition, you may use the plate which is not divided | segmented according to the item.

“Plate” was made of the same material as the finished surface of the renovation work. If the sheet is waterproof, the sheet is processed into a predetermined plate shape. If it is a plate-like ceramic roofing material, the material itself is used. If it is an outer wall material such as siding, the surface layer material is used. It is processed into a shape and is used in which symbol information such as characters, figures and codes is engraved. The engraving can display characters, figures, symbols, etc. so that information is not lost by engraving in the thickness direction of the material using a laser device or the like.
“Installing on the finished exterior finish surface” means installing on the exterior repair surface in the same manner as the repair work. For example, it installs by the same method as the connection method used when connecting the joints of sheet materials. More specifically, it means that the installation is performed by the same method as the actual renovation work, such as integration (fusion) in which the vinyl chloride sheet is melted with hot air, or integration (welding) in which it is melted with a liquid solvent. In addition, the sheet waterproofing method can employ a mechanical fixing method (disk steel plate) or an adhesive method in which the sheet is pressure-bonded with glue (adhesive) to the waterproof base. These also refer to the installation of plates on the exterior repair surface in the same manner as the actual repair work.

“Deterioration diagnosis acceleration test” refers to a weather resistance test, a foreign matter contact test, an environmental load test, and the like of a finished member. For example, for a waterproof sheet, the weather resistance test includes surface change and shrinkage by a testing machine such as metal halide, sunshine weather, xenon weather, or exposure to an Arizona light collector. “Acceleration test etc.” includes predicting the progress of deterioration of a member by computer simulation.
“For each part of the building” refers to one closed area, and one area on the veranda, the rooftop, or the roof is one unit even on the same floor. Moreover, it is good also as 1 unit for every hierarchy.
“Basic frame” refers to a so-called skeleton made up of foundations, columns, beams, outer walls, floors, and roofs. In addition, the “exterior component member” is, for example, a waterproof base material, an insulating sheet, an insulating board for walking, and a vinyl chloride waterproof sheet as a surface material if it is a waterproof sheet for a flat roof. The “design useful life” refers to the useful life set as a result of technical analysis of durability by performing the deterioration diagnosis acceleration test of (3).

“Based on the description information of the plate installed on the finishing member” means that the description information of the last repair work period of the plate is used for calculating the service life.
In addition, “the renovation work is divided into an exterior structural member that is exchanged together with the finishing member and an exterior structural member that remains without modification” means that the structural material of the intermediate layer of the exterior structural material does not have a plate. For example, at the time of renovation, the insulating sheet (insulating board), which is a constituent material of the intermediate layer, is regarded as the same useful life as the surface material (e.g., 10 years, 15 years) and is replaced with the surface material. The base material is regarded as the same useful life as the basic chassis (eg 60 years) and is not replaced. That is, it means that the component is handled in a choice of a member whose replacement time is matched with the surface material and a member that is treated as a basic casing and not replaced. Therefore, if the waterproof base material has a useful life of 30 years, the waterproof repair work in the 15th year after construction will only repair the seat, and the repair work will also include the base material in the 30th year after construction. It is. The reason why the repair plate is not stretched on the member that does not appear on the surface in this way is that the group of members of the intermediate layer covered with the sheet is not exposed to the harsh environment of the outside world, and the useful life of the production specification of the member may be out of order. Because it is rare.

  “A maintenance program is provided” means that a resident, manager or owner of the building holds the information as a sheet or computer data for the maintenance of the building (Japanese Patent Laid-Open No. 2001-159190). ), Or that the house maker is doing so, and that the plan can be corrected as appropriate by the member deterioration diagnosis through periodic inspections. For example, it can be maintained by using a building maintenance program management system described in JP-A-2002-328970, creating data, inputting a correction, outputting a sheet, and the like. In addition, “the actual repair work time corresponding to the planned repair work time and the design useful life thereof are recorded” means that, as shown in FIG. 2, for example, the repair work (1 The actual performance of the renovation work (what was done in the 15th year) and the design life (30 years) of the members actually selected and constructed for the exterior work are stamped on the plate. If you are.

According to (1), it is possible to maintain the repair work record and history information in accordance with the life of the finishing member. That is, by using the same material as the finishing member for the repair work, the same durability as the finishing member for the repair work can be secured, and the repair work history information does not disappear. In particular, if it is installed on the repair surface of the exterior by the same method as the repair work, the same durability can be secured for the durability of the finished member surface and the fixed portion of the plate, and the repair work history information will not disappear.
By installing a plate every time a renovation work is performed, the building information such as the implementation time and specifications of the building to be renovated can be acquired and confirmed on site.
By installing plates, it is possible to reduce the time to search for pre-managed data in the event of an emergency response such as a disaster (contamination, etc.) or other malfunctions. can do.

According to (2), it is possible to secure a specimen for a deterioration diagnosis test without damaging the waterproof state, and to perform a test for necessity of replacement.
According to (3), it is possible to retain the record and history information of the actual renovation work with respect to the finished member in which the originally designed service life is clearly specified.
According to (4), it is possible to correctly maintain a repair history that is different for each part in one house, and there is no complication of information.
According to (5), if a periodic inspection or repair work is performed based on the correct repair history described in the finished member, the repair work can be properly completed over the useful life of the basic housing of the building. In addition, the constituent material of the intermediate layer of the exterior constituent material can be replaced in synchronism with the finishing member, thereby consolidating and simplifying the repair work, no leakage, and hassle-free.

According to (6) and (7), the original repair plan is managed in accordance with the durable life of the basic chassis, and detailed and accurate repair work results and history information are surely put on the site. As a result, it is possible to maintain a complete maintenance for residents, house makers and maintenance companies.
According to (8), it is possible to keep the specifications of the exterior members, the records of construction contents, and history information from the stage of the new construction as well as the stage of the renovation of the building, and (1) to (7 Together with the renovation method, the building is maintained and managed consistently until the end of its durable life.
According to (9), for example, it is possible to form and maintain a building stock that contributes to social capital, such as the long life house ^TM proposed by the applicant (Japanese Patent Laid-Open No. 2001-159190).

  FIG. 1 is a partial cross-sectional perspective view showing an example of a cross-sectional configuration of a building according to the present invention, which is a configuration of a roof before performing a sheet waterproofing renovation work in a steel-framed flat roof building. The “basic frame” of the building is composed of a rectangular frame steel pipe and steel frame on a continuous reinforced concrete foundation, and a frame structure (frame) made of H-shaped steel beams. The shelter is made up of plates. In addition, the “exterior component covering the basic casing” is formed by laying a waterproof base panel that also serves as a heat insulating material on a floor board surface 4 formed of a lightweight cellular concrete panel to form a waterproof base 3, and an insulating material thereon 2a (new insulation material 2Aa after renovation) is laid to form insulation sheet (insulation board) 2 (new insulation sheet (insulation board) 2A after renovation), and finally sheet material 1a (new renewal sheet material after renovation) 1Aa) forms the waterproof sheet 1 (the newly installed waterproof sheet 1A after repair). Then, the plate 100 is installed at a predetermined position on the sheet 1 (1A).

As the waterproof base material 3a used for the waterproof base work, as described in JP-A-4-60047 and JP-A-2001-98714, a panelized material is laid.
The insulating material 2Aa used for the renovation work is the same as the insulating material 2Aa used at the time of new construction, or a material that has been appropriately improved in technology. Using a glass fiber cloth sheet of a certain width, the insulating material 2a adjacent in a certain direction is laid with an allowance. (When the waterproof sheet surface is used for walking as in the case of rooftop use, a calcium silicate board may be used for the insulating material 2a.)

The waterproof sheet material 1Aa used for the renovation work is the same as the waterproof sheet material 1a used at the time of new construction, or the one that has been appropriately improved in technology. In this embodiment, the waterproof sheet is made of soft vinyl chloride, the sheet thickness is 2.0 mm, and fiber yarns such as reinforcing resin are contained in a lattice shape (for example, Japanese Patent Laid-Open No. 58). -123960, JP-A-58-124645, etc.). Sheet material 1Aa is a product of rolled roll (width 1000-450mm) spread in a certain direction on site, secures an overlap allowance (overlap allowance 50mm) 1Ab on the sheet adjacent in the width direction, It is assumed that the waterproof sheet 1A has a sheet surface that is integrated with the roof surface by fusing or by welding with a liquid solvent.
The plate 100 is fixed to the wall surface of the rising 6b of the parapet of the newly installed waterproof sheet 1A after the repair by the same method (whether it is welded by hot air or by a welding agent).

(Plate history information and specimen)
A description will be given of the plates used to maintain the history of renovation work on the building exterior. Since the plate 100 is substantially the same in terms of durability without any special special waterproofing measures, the plate 100 has the same production lot or the same production period as the waterproof sheet material to be brought into the site repair work. , In advance at the factory. The shape of the plate 100 is processed into a size of about 100 mm in length and about 300 mm in width and 2.0 mm in thickness.
The method of leaving the history information of the renovation work described on the plate 100 is to use characters, figures, etc. indicating “sheet standard or specification”, “actual construction date of renovation work”, “design life of sheet material”, etc. Or by imprinting a symbol. In other words, the engraving represents characters, figures, symbols, and the like by engraving about 0.8 mm in the thickness direction with respect to the thickness of 2.0 mm using a laser device. Ensure that information is not lost by renovation work. The plate 100 is divided into several sections, for example, A, B, C, X, and Y sections. The plate 100 is manufactured separately for each necessary information type. In addition, although the content of the information stamped on the plate 100 is centered on specification information that affects the progress of deterioration, other information can also be included.

Moreover, the test piece X, Y can also be provided in the plate 100. FIG. In order to chemically analyze the progress of sheet material aging due to the influence of the external environment such as ultraviolet rays due to natural exposure indoors, it is prepared so that it can be cut and used for each deterioration test without cutting a healthy waterproof sheet surface finish. To do.
As a result, it is possible to follow up with regular inspections on buildings and parts whose actual deterioration progresses faster than the original design, and there is no leakage of inspection information, and individual responses can be made reliably.
Moreover, the exterior finishing member used for the repair is a member whose useful life is determined by an accelerated test for deterioration diagnosis or the like. Here, the accelerated test of the deterioration diagnosis refers to a weather resistance test, a foreign matter contact test, an environmental load test, and the like of the finished member. For example, the waterproof sheet is subjected to surface change and shrinkage as a weather resistance test by using a testing machine such as metal halide, sunshine weather, xenon weather, or exposure to an Arizona condenser. The same applies to roofing materials and exterior wall finishing members. In addition to the accelerated test, the deterioration diagnosis can be performed by computer simulation.

  In particular, it can be applied to a building having a maintenance program to be described later (FIGS. 6 and 7). By increasing the number of test piece parts (X, Y) according to the number of inspections corresponding to the building life plan, Until the end of the service life (design life of the basic chassis), chemical analysis is performed as appropriate, and based on the actual progress of deterioration, whether or not repair work at that time is necessary and maintained as planned in the future maintenance program. It is possible to select (judgment) whether the plan should be revised or to review the plan, predict the timing of the next and subsequent renovation work, and re-plan (review) the maintenance program.

  FIG. 2A is an example of a plate. In the information described in each part of the plate 100, the first term a1 of the A part is the sheet thickness (2.0 mm). The second term a2 is a sheet manufacturer name (P company). The third term a3 displays the actual construction year (2002) of the repair work. B of B section displays the construction month (August) of repair work. The fifth item c1 of part C displays the construction area of the repair work and the name of the contractor. In the sixth section c2 of the C section, the main branch and construction department signature under the jurisdiction of the house maker who performed the renovation work is displayed. The X part and the Y part are test pieces. In this embodiment, two places are provided at both ends of the plate.

FIG. 2 (2) is a plate provided with a section D corresponding to the maintenance program provided for the building, so that the results of periodic repair work corresponding to the maintenance program plan can be understood. In this example, “15” indicating the 15th year of the first repair work is engraved on d1 of the plate. Further, d1 is marked with “1 (first time)”, which is the result of the number of repair works. Moreover, d3 is the specification name (S) of the finishing member used for the repair work, and d4 is engraved with the design useful life (15 years) of the member actually used for the construction.
As another example, in d2, instead of “1 (first time)” indicating the number of times of renovation work, the first time “15” in the maintenance program plan, “2 (second time)” Instead of this, it may be the one indicated by the “30” year.

In addition, you may symbolize 15 years and 30 years as A, B, etc.
As a result, the result of the renovation work is recorded in association with the plan of the maintenance program provided in the building, and the history information is retained.
In addition, when installing this plate in the construction of a new building, the same procedure is applied, and the stamping of the specifications of the exterior materials at the time of new construction and the contents of the maintenance program (materials, design service life, next maintenance time, etc.) is pasted. wear.

(Plate installation position, installation location)
It is necessary to install the plate 100 at a position where it can be easily identified at the time of carrying out the repair work of the waterproof sheet in the future. It sticks to the rising part of the buttocks and parapet part. This is because the visibility is good for the inspector of the periodic inspection and the worker of the renovation work, so that it cannot be stepped on by human walking. The plate 100 was fixed to the newly installed waterproof sheet surface 1a after the refurbishment by the same method as that for the renovation work (whether it was fused by hot air or by a welding agent).
The number of installation places is basically one place on each floor, but areas (veranda, ridges, lower house parts, etc.) divided by the outer wall and the waist wall are installed for each part and for each area.

  FIG. 3A is a diagram illustrating an example of an installation position of a plate. (1) is an installation example of the roof end of the rooftop, (2) is an installation example of the rooftop parapet rising part, and (3) is an installation example of the oblique line restriction cut roof part corresponding to the north oblique line restriction of the land roof , (4) is an installation example of a veranda part waist wall rising part. Even in the same region or region, separate plates 100 may be installed in the flat portion of the roof portion and the slope (hatched line cut portion) on the north side. This is because the progress of degradation differs depending on the exposure conditions (difference in received light amount), and the timing of the repair work may differ. That is, as shown in FIG. 3-2, when the roof has a plurality of waterproof parts, the rooftop floor is subjected to the renovation work for the entire region at the same time, so the plate 100 is only one place. On the second floor, since it is composed of two parts, a veranda and a bowl, renovation work for these parts may be performed at different times, so the plate 100 is installed for each part.

(Renovation work flow on the roof and veranda tarpaulins)
FIG. 4: shows the example of a flow of the repair work which concerns on this invention in the block diagram (cross-sectional view) of the roof parapet part and outer wall part in a building of a steel framed flat roof structure.
(1) A prefabricated steel sheet with a waterproof sheet is newly installed in the parapet part (Japanese Patent Laid-Open No. 01-310049).
Prefabricated steel sheets 1Ad and 1Ae with waterproof sheets are overlapped on the existing waterproof steel sheets 1d and 1e that have already been installed in the previous construction, and fixed with screws at the two locations of the floor and the boundary of the parapet tip 6a and the parapet rising (lower part) 6b. (Not shown). This is because if the existing waterproof steel plates 1d and 1e are peeled off, the waterproof base will be damaged.
(2) Removal of the existing sheet Next, a member group above the waterproof base material 3, that is, the existing waterproof sheet 1, a mechanical fixing device (disk-shaped steel plate) for fixing the sheet, and the existing insulating material 2 (glass fiber) Remove the cross sheet.

(3) Laying procedure of newly installed sheet The general section lays the insulating material 2A (glass fiber cloth sheet or calcium silicate board for walking) newly installed on the surface of the waterproof base 3. After laying the insulating material 2A, the disc-shaped steel plate 1Ac is interspersed on the insulating sheet (insulating board) with a dedicated screw threaded at the tip of the body length, and the dedicated screw penetrates the insulating material 2A and the waterproof base 3 In this way, the insulating material 2A waterproof base 3 is integrally fixed to a predetermined position of the floor board 4. After fixing the disk plate 1Ac, the sheet material 1 is laid on the waterproof base 3 while laying the new waterproof sheet 1Aa in a certain direction, and the sheet material is welded with a liquid solvent (or hot air fusion) to be integrated and waterproof. Sheet 1A is formed. The sheet material 3 in a roll shape (widths of 1000, 800, 600, and 450 mm are appropriately used) is laid in parallel with each other while securing an allowance of about 1 mm. By welding to the disk-shaped steel plate 1Ac and the waterproof sheet prefabricated steel plates 1Ad, 1Ae, the waterproof base 3 is spotted (insulation method). The disc-shaped steel plate 1Ac is fixed by inserting a syringe from the finished surface of the waterproof sheet 1A and injecting a solvent to integrate the back surface of the sheet 1A and the surface of the disc 1Ac. The parapet portion is integrated by solvent welding by superposing the sheet material of the general portion on the sheet pieces of the waterproof sheet prefabricated steel plates 1Ad, 1Ae.

(4) Plate installation The plate 100 is installed at a predetermined position near the entrance / exit. The plate 100 of the same material in which the history of the repair work is engraved on the sheet material 1Aa is welded to the rising wall surface 6b of the parapet with a solvent (by the same method as the integration of the sheets) and fixed. As a result, the same durability as the actual waterproof sheet is maintained, and the recorded information by the stamp is not erased.
(5) Although the present embodiment replaces the existing sheet 1a, an insulating sheet (insulating board) 2A is formed on the existing sheet 1a with an insulating material 2Aa, and the waterproof sheet 1A is overlaid. Also good.

  Next, an embodiment of the invention of claim 4 will be described. In the steel frame building of the flat roof structure of FIG. 1, the basic frame 7 has a design life of 60 years, the sheet material 1a and the tarpaulin 1 have a design design life of 20 years, and an insulating material 2a. Similarly, the insulating sheet (insulating board) 2 formed of (glass fiber cloth sheet or calcium silicate board) has a design life of 20 years (however, the board is semi-permanent) and is formed of a waterproof base panel material 3a. The waterproof base 3 having a service life of 60 years is used and assembled. Although the said plate 100 is installed in the waterproof sheet 1 which is an exterior finishing member. The plate 100 is not installed on the insulating sheet (insulating board) 2 or the waterproof base 3 made of the constituent material of the intermediate layer. In addition, the screw and solvent used for fixing each member are also selected in accordance with the design life of each material.

  Then, the waterproof sheet 1 formed of the sheet material 1a is replaced by a repair work after 20 years from the delivery, and at the same time, the insulating sheet (insulating board) 2 is also replaced together. This is because it is equivalent to the design life of the sheet material 1a and is cut together when the waterproof sheet 1 is cut. On the other hand, the waterproof base material 3 is not replaced. This is because the design life is the same as that of the basic casing 7, and the sheet material 1a and the insulating material 2a are not damaged even by cutting. That is, in this example, regarding the repair timing of a plurality of exterior component members, the intermediate layer components that are modified in accordance with the exterior finish member, and the intermediate layer that is treated as being equivalent to the basic casing and that is not replaced at all over the useful life of the building The construction work is divided into two parts and the time for repair work is determined.

In another example, when the sheet material 1a has a design life of 15 years and the waterproof base panel material 3a has a design life of 30 years, the sheet material 1a Only the waterproof sheet 1 and the insulating sheet (insulating board) 2 formed of the insulating material 2a are repaired, and the repair work including the waterproof base 3 is performed 30 years after delivery.
The reason why the plate 100 is not installed on the insulating sheet (insulating board) 2 or the waterproof base 3 in this manner is that the member group (2, 3) of the intermediate layer of the exterior component member covered with the sheet material 1 This is because, without being exposed to a harsh environment, it is rare to upset the service life (design service life) designed in the initial stage.

In addition, since this example is a waterproof sheet structure of a building assembled with a member whose design life is shorter as the member closer to the surface finish member, for example, the waterproof base material at the bottom of the sheet is ahead of the surface sheet material. There is no need to replace the battery at the end of its lifetime. That is, the sheet material 1 on the sound exterior surface is peeled off, the waterproof base material 3 is replaced, and the sheet material 1 is newly provided again. Only the sheet material 1 on the exterior surface needs to be replaced.
Next, embodiments according to claims 5 to 7 will be described.
FIG. 5 is a building of a steel framed flat roof structure described above, in which a basic casing, an exterior member, and an embedded equipment member are used as target members for a regular maintenance plan. And the lifetime of the exterior member and the lifetime of the embedded equipment member are all integers of the lifetime of the basic chassis, and the overall lifetime of the basic chassis, Based on the service life, the lower service life is set to 1 / integer of all the upper service lives, and is regularly maintained at intervals of an integral multiple of the minimum service life of the lower service life It is a building designed to perform replacement and repair).

  Here, the “designed building” means that the members constituting the building in order to carry out the renovation work at an interval of an integral number of the basic frame based on the useful life of the basic frame is an integral part of the basic frame. It is a building that is assembled using members having durability that satisfies the service life, and in which the members are combined so that the target member is always maintained before the target member reaches the design service life. In this example, the longest service life of the building is 60 years, which is the service life of the basic chassis. In addition, the roofing material for land roofs and roofing materials for sloped roofs, which are exterior members, have been selected for 30 years of design life, 15 years for the outer wall spray coating, and 30 years for the sealing material between the outer wall panels. The components of the service life are selected, the water supply / hot water supply piping for the buried equipment is selected for the design life of 30 years, and the drainage piping is 60 years.

  In the building of this example, from the viewpoint of preventing destruction due to deterioration, the maintenance target member is replaced with a healthy member a little before the limit of the durable life of the member (before the failure occurs). It is a building that is assembled so that it does not become too late due to the failure of members due to the progress of deterioration. For example, if a design life of 15 years is required when a certain member is selected, a member with a degradation diagnosis test result of 15 years or more (using a test result obtained with a margin of 20 years) is used. Secure.

Each member is a member whose service life is predicted by an accelerated test for deterioration diagnosis.
Here, the acceleration test for deterioration diagnosis refers to a weather resistance test, a foreign matter contact test, an environmental load test, and the like of the basic chassis. For example, a steel member confirms the progress of rusting, and the concrete confirms the progress of neutralization of a reinforcing bar by a predetermined cored sample. As for the exterior, the outer wall spraying material, roofing material, and waterproof sheet are subjected to surface changes and shrinkage tests such as metal halide, sunshine weather, and xenon weather, and exposure to Arizona light collectors.
In addition to the accelerated test, it is also possible to predict the progress of deterioration of the member by computer simulation.
And, this building holds the history of exterior renovation work by the method of claims 8 to 8.

Next, the building maintenance program will be described.
FIG. 6 shows a maintenance program provided for the building. Here, “a maintenance program is provided” means that a resident, manager, or owner of the building holds the information as a sheet or computer data for the maintenance of the building (Japanese Patent Laid-Open No. 2001-2001). No. 159190), or that the house maker is doing so, and means that the plan can be appropriately corrected by a member deterioration diagnosis by periodic inspection or the like. For example, it can be maintained by using a building maintenance program management system described in JP-A-2002-328970, creating data, inputting a correction, outputting a sheet, and the like. This example is a building maintenance program in which the basic enclosure, exterior members, and buried equipment members are the target members for regular maintenance plans. The timing of the renovation work to be performed is planned.

  In the initial plan, each part is allocated to 30 years and 15 years for repair work. As for the exterior, waterproofing of waterproof sheets on flat roofs and periodic inspection of sloped roofs (roof roofing materials) are 3 months. 1st, 2nd, 5th, 10th, 15th, 20th, 25th, 30th, 40th, 50th years. Moreover, the replacement of tarpaulin tarpaulins is planned for the 30th year. Gradient roofs (roofing materials) are repaired and replaced every 15 years.

(Test pieces)
At the time of periodic inspection, the house maker confirms “plate 100 installed on finishing member”. In the case of the waterproof sheet 1, when it was constructed to grasp the age of the sheet material 1a, the last time is the renovation work performed from the date of delivery (the start date of the useful life), or the previous renovation Read information that affects the progress of deterioration, such as the design life of the sheet material 1a used in the construction and the thickness of the sheet material 1a, and visually compare, for example, samples of members prepared for deterioration over time. To understand the deterioration status. As a result, when it is considered that the deterioration state is progressing as compared with the number of years elapsed, the test pieces X and Y of the plate 100 installed on the finishing member surface are peeled off from the finishing member surface and indoors. Tests for chemical analysis can be conducted to assess the adequacy of the next refurbishment schedule planned for the current maintenance program.

The building may be maintained according to the maintenance program. However, unexpected deterioration may occur due to factors such as exposure to ultraviolet rays in the construction site and the surrounding environment, and it is necessary to quickly and accurately grasp the state of deterioration and respond to future predictions.
On the other hand, the building according to claim 8 refers to the plate in the periodic inspection during the periodic inspection performed during the member replacement period of the maintenance program, and further confirms the progress speed of deterioration with the test piece. In addition, it is possible to set the time when the actual replacement should be performed by measuring the remaining life after confirming the degree of deterioration just before the renovation work. After the test, a sheet piece inscribed with the next replacement time can be installed at the place where the test piece is cut out.

In this way, by combining the maintenance program with a method of leaving the history of the renovation work of the present invention, it is possible to carry out thorough maintenance management for residents and maintenance contractors.
In addition, it is convenient that the number of test pieces of the plate can be tested each time if the number of test pieces is provided for the remaining periodical inspection and the number of repair work according to the building maintenance program.

(Example of sloped roofing material)
FIG. 7 shows another embodiment of the present invention, which is an application example of the repair work of the roof covering material that is spread on the roof panel having the gradient roof structure. The plate 100 uses a roofing material (ceramic finishing member) 21, and specification history information is imprinted on the plate 100 in the same manner and content as the waterproof sheet material 1 described above.
In the configuration of the sloped roof structure, the lower roofing material 22 is laid on the surface of the base plate 23 that is the roof base surface, and the roofing material 21 is fixed by screws 21a and adhesives 21b. The plate 100 is bonded to the surface of the roofing material 21 with the same material as the adhesive 2b. In the basic frame (design life span of 60 years), roofing materials will be repaired (protective paint) in 15 years and will be replaced in 30 years. The replacement work will be carried out together with the underlaying material 22, but the roof panel material base plate will not be replaced because it has a design life of 60 years, which is the same as the basic frame.
The renovation method described above can also be performed after installing the plate in the same way at the time of new construction.

  The present invention can be suitably used in the field of building renovation work.
