シュミレーション原図施工情報作成工程で作成された配管施工情報は、上述したように、施工現場での実測寸法をもとにシュミレーションを行って決定されたものであるから、色々な不具合を事前に想定でき、その対策を十分講じたものとなっているので、管材料切断加工工程において、高精度で高品質の加工製品を提供できる。修正工程で作成された配管施工情報にしたがって、施工現場とは別場所の加工工場内で管材料切断加工が行われる。管材料切断加工工程は、上記表１に示す部品表のみを見るだけで必要な切断加工が行われるため、他の図面等は補助情報として参照するだけでよい。
管材料切断加工工程においては、管材を同一管種サイズごとに分類し、また、長いサイズの順に並べ替えて加工することで、管材の無駄が管材の１％以下と最小限に抑えられ、管材が殆ど廃棄されないだけでなく、配管施工されなかった管材は工場で在庫として保管され、他の工事場所で再利用することができる。又、現場実測工程が終了しておれば、その後の建築物本体工事、関連設備工事等の影響により配管施工工程の着工時期が遅れたとしても、管材料切断加工工程までの工程を順調に進められるので、配管施工工期の遅れを最小限にとどめられる。
配管施工工程を着工する直前に、管材料切断加工工程で加工された管材等を工場から施工現場に搬入し、配管施工を行う。貫通孔等の変更を修正された配管施工計画によって行い、切断加工された管材等を管材寸法図及び管材記号図に沿って組立配管すればよい。この際、施工現場での切断加工を行わないので、施工現場で発生する産業廃棄物を最小限に抑えられる。又、現場合わせがないため、誤取付が容易に顕在化するので、配管ミスを行ったままで施工を終えることがない。また、管材の保管は施工時まで現場内に搬入しないため、現場で直射日光にさらされたり、風雨、埃などの影響も少なく商品管理も充実し品質はもとより衛生面でも非常に安全である。又、最小限必要な最終工程の配管施工工程のみを現場で行うため危険な現場に居る時間が短く、切断加工工場内での加工作業は工具の準備等が現場に比べて製品精度が向上し、予め管を切断加工し施工時期まで待機し、施工時期に一気に組み立てるので、残業や徹夜での作業もずっと減り、作業員の労働条件が非常に改善される。
更に、修正された配管施工計画図に記入されている配管関係の諸寸法が、完成時の配管関係の諸寸法と必ず一致するため、修正された配管施工計画図を完成図とし、この図に基いてメンテナンスが可能で、メンテナンスの質が向上するという効果がある。

上述の実施例においては、本発明の建築設備工事の配管施工システムは、切断加工工場において管材の切断加工を行うとして説明したが、切断加工に加えて、配管施工情報にしたがって加工工程の後若しくは加工工程と併行して、配管の組立の一部を行う工程（本発明の工場内組立工程に対応）を行うとしても良い。
現場実測工程前に配管施工仮情報として施工計画図のみを作成する場合を例として説明したが、これに限定するものではなく、管材寸法、管材記号図および部品表に対応する情報の全部または一部を配管施工仮情報として作成してもよく、配管施工仮情報を一切作成せず現場実測工程の後にすべての配管施工情報を直接作成してもよい。
【０００９】
【発明の効果】
本発明は配管施工計画図と実測により得た情報に基づきシュミレーションを行い、その結果、施工現場とは別の工場で配管切断加工を行い、切断された管材を現場に搬入し配管施工のみを施工現場で行う構成であるので、作業時間に無駄がなく、作業性を向上させ、施工現場で発生する産業廃棄物を減少化し、配管材料を有効利用することができるという効果がある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a piping construction system for building equipment construction for a building fixed on land, and more particularly, to a piping construction system capable of carrying a previously cut pipe to a site and piping without deviation.
[0002]
[Prior art]
Examples of a system for performing piping construction design using a computer include those described in JP-A-58-225472, JP-A-6-55390, JP-A-8-314999, and JP-A-9-50452. Exists. Among them, the invention described in Japanese Patent Application Laid-Open No. 58-225472 discloses a method in which a model model created by a model engineering method is photographed by a stereo photographing technique, and a photograph of the model model is subjected to digital coordinate analysis by a plotter. Basic data of piping is created, the basic data is converted into actual dimensions and input to a computer, and a drawing such as a comprehensive piping plan drawing and a pipe cutting table are output. The invention described in Japanese Patent Application Laid-Open No. 6-55390 transfers piping design information to a computer, and from the transferred design information, uses piping materials on a processing line, cut lengths of pipes that can be cut, and usage information about the piping locations. The cutting machine is configured to extract and cut the pipe material into a predetermined length according to the processing information. The invention described in Japanese Patent Application Laid-Open No. 8-314999 discloses an assembly information database created by extracting assembly information from assembly drawings having connection information of end points for connecting parts, and creating a single-item pipe generated from a two-dimensional drawing of a single-piece pipe. The three-dimensional assembly data is generated based on the three-dimensional data and the assembly information. In the invention described in Japanese Patent Application Laid-Open No. 9-50452, the shape and orientation of members are registered in a computer so that they can be easily arranged on a piping drawing.
However, all of the above-mentioned inventions are intended to facilitate the cutting of piping and the creation of piping drawings, and cannot deal with actual piping work. This is because, in actual piping work on a land-fixed building, even if there is a slight error of about several mm between the land-fixed building and a pipe fitting, it is impossible to perform the piping work. None of the above-mentioned conventional techniques are actually measured on site, and simply cut the piping material according to the information obtained on the computer screen as it is, so there are applications for air conditioner piping etc. which are not affected by the presence of existing structures. However, it is not practically possible to use it for plumbing buildings that have been established on land. In other words, plumbing for buildings fixed on the land has many types of equipment construction (water supply and drainage, gas, steam, air conditioning equipment, firefighting equipment, etc.) as compared to other industries, and piping locations (for example, , Burial in the ground, wall surfaces, between floor and ceiling, etc.) are different, and the piping is complicated, so it is not always possible to construct at the position as shown in the construction drawing. However, the current situation is that plumbers measure and work locally on site.
[0003]
[Problems to be solved by the invention]
In the pipe construction method of the future building equipment construction, the pipe material is cut at the construction site in the order of the mounting process, so that there is much loss in the material. There has been a problem that much of the surplus material has been disposed of as industrial waste even though it can be used in a new state.
Further, since the cutting of the pipe material is performed in an external temporary work place on the site, the work is affected by the natural environment such as weather, and the work environment is poor for the worker, which causes a problem that the workability is reduced.
Furthermore, since the cutting work is started only when other works such as electric work have progressed to the extent that the pipe work can be performed, the cutting work start time is not clear in advance, and the cutting work waits. However, there is a problem that there is a time loss for the
Therefore, in the present invention, a previously designed piping construction plan is input to a computer, and the piping position based on the actual measurement value at the site is superimposed and written on the piping construction planning diagram. A simulation was performed in consideration of the deviation and error of the position, and the pipe material was cut and processed in advance at the processing plant according to the corrected piping construction plan drawing, and then carried to the site and the corrected piping construction planning drawing An object of the present invention is to improve the cutting work and on-site work by performing pipe construction while inquiring, without using unused pipes as it is as industrial waste, using the pipes without waste.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, an invention according to claim 1 of the present invention includes a step of creating a pipe construction plan based on structural information of a building body fixed on land, Based on the pipe through hole provided in the building body, a pipe support material, a pipe connection scheduled site in the building body, a pipe erection position, and a step of actually measuring these positional relationships at a construction site, A process of inputting a pipe construction plan diagram to a computer, and superimposing and filling in each position information obtained by the actual measurement on the pipe construction plan diagram displayed on the computer screen to create a simulation original drawing, on this simulation original drawing An error or deviation in the pipe length or position in the simulation original drawing is corrected by simulation of the shape or position of the structure or / and the pipe of the building body. And, according to the information obtained from the corrected piping construction plan, a step of cutting the piping material in advance at a place other than the construction site, and transporting the cut piping material to the construction site, the modified And piping the building body based on the piping construction plan.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
【Example】
An embodiment in which plumbing is performed for building equipment work under the floor of a building toilet will be described below with reference to the drawings.
FIG. 1 is a process diagram showing a process of a piping construction system for building equipment construction, FIG. 2 is a piping construction plan diagram, FIG. 3 is a simulation original drawing, and FIG. 4 is a revised piping construction plan diagram.
First, a description will be given of a piping construction plan drawing creation process. Based on the information on the structural drawing of the building body, a piping construction plan diagram shown in FIG. 2 is created as temporary piping construction information. In this piping construction plan diagram, the position dimensions of the route through which the piping passes are displayed, as in the construction diagram in the conventional piping construction method. For the material and pipe diameter, it may be displayed in the same manner as the construction drawing in the conventional piping construction method, but in the pipe material dimension diagram described later, the material pipe diameter for each pipe material is displayed along with the dimensions, so in the construction plan drawing The material is determined by the line color, and the tube diameter is determined by measuring the drawing.
FIG. 2 will be described in detail. The sewage pipe 1 descends from the upper floor, penetrates the wall 2, which is the main body of the building, through the through hole 3, connects to the toilet 4, the urinal 5, and the handwashing vessel 6 by a branch pipe, and descends to the lower floor. Says. The gray drainage pipe 7 descends from the upper floor, penetrates the wall 2 through the through hole 8, connects to the toilet 4, the urinal 5, the hand-washing container 6 and the drain 9 by a branch pipe, and descends to the lower floor. I have. The water supply pipe 10 descends from the upper floor, penetrates the wall 2 through the through hole 11, and is connected to the toilet 4, the urinal 5, and the hand washing container 6 by a branch pipe.
The on-site measurement process will be described. At the stage where the creation of the pipe construction plan drawing has been completed and the positional relationship between the pipe support and the pipe through hole attached to the building body and the building body can be measured on site, actual site measurement is performed. In the on-site actual measurement process, the positional relationship between the reference lines 12, 13 and the through holes 3, 8, 11, and the like is measured based on the piping construction plan.
After the process of inputting the piping construction plan drawing into the computer, a simulation original drawing creation process is performed using the measurement results obtained in the above-mentioned actual site measurement process.
The simulation original drawing creation process will be described. Based on the piping construction plan shown in FIG. 2, the positions of the reference lines 12 and 13 are set to be positive and the actual positions of the through holes 3, 8, 11, etc. obtained in the on-site actual measurement process are written in the piping construction plan. I do. Depending on the position and length of the pipe in the pipe construction plan, whether the pipe can penetrate through the through holes 3, 8, 11 of the building that has already been established, or the toilet 4, urinal 5, and hand washing container 6 It is examined whether connection of pipes to the like is possible, etc., and a simulation original drawing shown in FIG. 3 is created.
The correction process will be described. When the simulation original drawing shown in FIG. 3 is created, for a pipe that cannot be penetrated, for example, the penetration of the pipe can be reduced by performing a simulation such as enlarging the diameter of the through hole, changing the arrangement position of the pipe, and rearranging the branch pipe. Consider whether this is possible. The piping construction plan is modified according to the result of this examination, and a modified piping construction plan shown in FIG. 4 is created.
Various pieces of piping construction information are displayed in the revised piping construction plan diagram shown in FIG. For example, since the sewage pipe 1 at the portion indicated by the symbol A in FIG. 4 cannot penetrate the through-hole 3, it is shown that the sewage pipe 1 moves 36 from the position dimension shown in the piping construction plan diagram of FIG. I have. The branch pipe connection portion of the wastewater pipe 1 indicated by reference numeral B in FIG. 4 has a new arrangement because the joints overlap and the pipe cannot be formed, and the penetration portion C with the lower floor is enlarged. ing.
FIG. 5 is an example of a pipe material size diagram of the pipe construction method according to the embodiment of the present invention, and FIG. 6 is an example of a pipe material symbol diagram of the pipe construction method according to the embodiment of the present invention. FIG. 5 shows, as the pipe construction information, a material, a pipe diameter (for example, “100 VP”, “25HI”, etc.) and a pipe length of each pipe. In FIG. 6, an identification symbol of each pipe, such as “C-3” or “W-6”, is displayed as the pipe construction information. In the present embodiment, the tube material dimensional diagram and the tube material symbol diagram are separated from each other, but may be described on the same drawing. 5 and 6 do not describe the component information regarding the joints such as the L-shaped joint and the T-shaped joint. This is because a joint can be adopted or can be easily identified, and may be managed by attaching an identification symbol similarly to the pipe material.
The parts table shown in Tables 1 and 2 below was created by picking up pipe materials and joints from FIGS. 5 and 6. Table 1 is an example of a parts list for pipes in a piping method according to an example of the present invention, and Table 2 is an example of a parts list for joints in a method of piping in an embodiment of the present invention. In Table 1, as the piping construction information, the type of piping system ("Piping system" column), the part identification code ("Symbol" column), the material pipe diameter ("Pipe type"), and the quantity ("Quantity" column) Are displayed, and a column for “confirmation of pipe cutting” and a column for “confirmation of pipe marking” used in the tube material cutting process are also provided. Table 2 shows the type of piping system ("piping system" column and "symbol" column), the component identification symbol ("joint type" column), and the quantity ("quantity" column) as piping construction information.

[Table 1]

[0007]
[Table 2]

As described above, the piping construction information created in the simulation original drawing construction information creation process was determined by performing simulations based on the actual measurement dimensions at the construction site, so various problems can be assumed in advance. Since such measures have been taken sufficiently, high-precision and high-quality processed products can be provided in the tube material cutting process. According to the pipe construction information created in the correction process, a pipe material cutting process is performed in a processing plant at a location different from the construction site. In the pipe material cutting processing step, necessary cutting processing is performed only by looking at only the parts table shown in Table 1 above, so that other drawings and the like need only be referred to as auxiliary information.
In the pipe material cutting process, the pipe material is classified according to the same pipe type size, and the pipe material is rearranged in the order of the longest size and processed to minimize waste of the pipe material to 1% or less of the pipe material. Not only is it not disposed of, but the tubing that has not been plumbed is stored in stock at the factory and can be reused at other construction sites. In addition, if the actual site measurement process has been completed, the process up to the pipe material cutting process will proceed smoothly even if the start of the piping construction process is delayed due to the effects of the subsequent construction of the building itself and related facilities. As a result, delays in the plumbing work period can be minimized.
Immediately before the start of the pipe construction process, the pipe material or the like processed in the pipe material cutting process is carried into the construction site from the factory to perform the pipe construction. The change of the through hole and the like may be performed according to the corrected piping construction plan, and the cut pipe material or the like may be assembled and piped according to the pipe material dimension diagram and the pipe material symbol diagram. At this time, since no cutting processing is performed at the construction site, industrial waste generated at the construction site can be minimized. In addition, since there is no on-site adjustment, erroneous mounting easily becomes apparent, so that there is no case where the construction is completed with a piping error being made. In addition, since the tube material is not stored in the site until the time of construction, it is not exposed to direct sunlight on the site, the influence of wind, rain, dust, etc. is small, the product management is enhanced, and not only quality but also hygiene is very safe. In addition, since only the minimum necessary piping work, which is the final process, is performed at the site, the time spent at a dangerous site is short, and the machining work in the cutting factory improves the product accuracy by preparing tools and the like compared to the site. In addition, since the pipe is cut in advance and waited until the construction time, and assembled at a stretch at the construction time, overtime work and all-night work are greatly reduced, and the working conditions of the workers are greatly improved.
Furthermore, since the various dimensions related to piping written in the revised piping construction plan drawing always match the dimensions related to the piping at the time of completion, the revised piping construction plan drawing was taken as the completed drawing and this drawing Maintenance can be performed on the basis of this, and there is an effect that the quality of maintenance is improved.
[0008]
In the above embodiment, the pipe construction system for building equipment construction of the present invention has been described as performing the cutting process of the pipe material in the cutting factory, but in addition to the cutting process, after the machining process according to the piping construction information or A step of performing a part of the pipe assembly (corresponding to the factory assembling step of the present invention) may be performed in parallel with the processing step.
Although the case where only the construction plan drawing is prepared as temporary construction information before the actual site measurement process has been described as an example, the invention is not limited to this. All or one of the information corresponding to the pipe material dimensions, the pipe material symbol diagram, and the parts list is described. The section may be created as temporary pipe construction information, or all the pipe construction information may be created directly after the on-site actual measurement process without creating any temporary pipe construction information.
[0009]
【The invention's effect】
The present invention simulates based on the piping construction plan drawing and the information obtained by actual measurement, and as a result, cuts the pipe at a factory different from the construction site, carries the cut pipe material to the site, and performs only the pipe construction Since the construction is carried out on site, there is an effect that there is no waste of work time, workability is improved, industrial waste generated at the construction site is reduced, and piping materials can be effectively used.
