Description

  The present invention relates to a design drawing creation system for creating a construction design drawing, an integration system that is connected to the design drawing creation system and calculates construction costs, and has various systems for managing various works. It relates to the construction management system.

  Assuming that the above system is applied to, for example, construction work, the number of all materials such as pillars, beams, walls, etc. used in building properties whose design drawings are shown by CAD (Computer Aided Design) drawings is integrated. Patent Document 1 discloses a technique related to a building integration system for this purpose. In this method, the data input to a computer equipped with software for integration while the operator has visually checked and marked the CAD drawing (design drawing) output on paper has been improved. It is streamlined. A system based on this technology has a multi-screen composed of a plurality of displays, and each of the plurality of displays, for example, a display means (overall view screen) for displaying design drawing data and a part of the design drawing data are enlarged. It functions as an enlarged display means (detailed picture screen) to be displayed and a screen display means for integration (integration screen) for inputting information for integration. Then, for example, information is temporarily stored by double-clicking the mouse on the enlarged display means, and this information is transmitted to the program for integration by double-clicking at a predetermined location on the screen display means for integration. Then, the integration is performed.

  Further, Patent Document 2 discloses a technique related to an integration system for piping equipment that can easily and easily collect information from a piping drawing and totalize the information. This is related to the estimation for estimating the material cost and labor cost for piping work such as air conditioning equipment that is performed as ancillary work for the construction of the building. Since most of the operations for summing up each item are manual operations, the operation is very time consuming, and it is proposed for the problem that there is a risk of erroneous writing or transcription mistakes. According to this, for example, a digitizer on which a piping drawing is placed and detects a length dimension between two points of a piping member indicated by an indicating means such as a stylus pen, and individual information that cannot be input from this digitizer, for example, An input means for inputting by manual input or the like and an operation unit for performing an operation based on the input information are provided, and the operation results are totaled and integrated.

  According to this characteristic configuration, since the design information acquisition unit for integration for acquiring the design information for integration is provided separately from the design drawing information input unit, for example, an operator on the integration side reads from the design drawing. It is also possible to input. And, since it is configured to be able to accumulate the cost of the outer pipe work using the design information for integration acquired in the design drawing information input unit or the design information acquisition unit for integration, design drawing information is obtained from the design drawing creation system. Even if it is not available, it can be used as a general-purpose integration system.

  In addition, the integration system according to the present invention reflects the update from the update information input unit that updates the acquired design information for integration to obtain new design information for integration, and the updated design information for integration. An update information output unit that outputs the design drawing information is characterized.

Is output. Details will be described later.

[Design drawing creation system]
FIG. 2 is a block diagram showing the configuration of the CAD system according to the embodiment of the present invention. As shown in FIG. 2, the CAD system 1 according to the present embodiment performs so-called drawing of the design drawing D2 by the drawing control unit (CAD) 12 based on the construction specification D1, and integration by the design information input unit 11 for integration. The design information J0 necessary for integration is input. The design drawing D2 also includes integration design information J0. The design information J0 for integration input by the drawing control unit (CAD) 12 and the design information input unit 11 for integration is designed as design drawing information J1 by the design drawing information management unit 14 (design drawing information output unit 13). Collectively managed in association with construction identification information J2 given for each construction.

  As shown in FIG. 2, the CAD system 1 outputs a design drawing D2 and design drawing information J1 as a product by the function. The design drawing D2 created by the drawing control unit 12 and the design drawing information J1 managed by the design drawing information management unit 14 are associated in the CAD system 1. Here, for ease of explanation, the design drawing D2 and the design drawing information J1 are separately illustrated and described. However, the configuration is not necessarily limited to a configuration that requires a plurality of electronic files on a computer. Instead, they may be integrated into one electronic file. Further, the design drawing D2 and the design drawing information J1 do not need to be a single electronic file, and each may be composed of a plurality of electronic files.

  In the present embodiment, the design information for integration J0 includes at least piping engineering information J3 that is information on the construction type, piping material, dimensions, etc. for the piping to be subjected to outer pipe construction, and the length of each underground depth of the piping. Extension information J4 according to depth, piping equipment information J5 which is information on equipment installed in the piping, and connection configuration information J6 indicating a connection configuration between the piping and the existing piping. Here, the extension civil information J4 and the pipe equipment information J5 are subordinated to the pipe civil information J3, and then the pipe civil engineering information J3 and the connection form information J6 are used to identify the outer pipe work. It is centralized and managed in association with. Information that is centralized and managed in association with the construction identification information J2 is output from the design drawing creation system 1 as design drawing information J1. The design drawing information J1 can be output in CSV format, for example.

  As described above, when the electronic file storing the design drawing information J1 and the electronic file storing the design drawing D2 exist separately, the following advantages are obtained. That is, as for the CAD 12 constituting the CAD system 1, an individual one owned by the construction company is used, and the functions of the integrating design information input unit 11 and the design drawing information output unit 13 are added to the CAD 12. The CAD system 1 can be configured. In this way, the construction management system can be introduced and expanded while utilizing the assets owned by each construction company.

  In the present embodiment, the above-described piping civil information J3, extension information J4 by depth, piping equipment information J5, and connection configuration information J6 are used as information constituting the design drawing information J1 (the same is the design information for integration J0). Of course, it is not limited to these. In the present embodiment, in order to facilitate understanding of the present invention, the description is limited to such information. Therefore, the information that is centrally managed in association with the construction identification information J2 and is output from the design drawing creation system 1 as the design drawing information J1 is not limited to the information input from the design information input unit 11 for integration, but is input from the CAD 12 Information may be included.

  FIG. 3 is a block diagram showing the configuration of the integrating system according to the embodiment of the present invention. The design drawing information input unit 21 of the integration system 2 receives the design drawing information J1 output from the CAD system 1 via the network system 3, and obtains the integration design information J0 necessary for integration. Here, the data is received via the network system 3, but the present invention is not limited to this and may be received via a storage medium such as a CD-R. Further, via the network system 3 in the present embodiment, the integration system 2 and the CAD system 1 may be directly connected as a relationship between the host and the remote, or designed using e-mail or the like. The drawing information J1 may be transmitted and received.

  Alternatively, the network system 3 may be a web system using the Internet. Similarly, there is a design drawing D2 output from the CAD system 1 on the network system 3 and a database 4 in which design drawing information J1 is stored. The integration system 2 can be operated from a screen on a web using a browser. Also good. In the integrating system 2, the design drawing information J1 may be obtained by designating a file on the database 4 on the browser screen.

  The integration design information J0 acquired from the design drawing information J1 received by the design drawing information input unit 21 is managed by the integration design information management unit 23. The integration design information management unit 23 manages information necessary for integration in the database 29 including other information such as the number of security personnel (guardmen) corresponding to the construction scale.

  The integration calculation unit 24 integrates the construction cost using the integration design information J0. In the block diagram of FIG. 3, it is recalled that the integration is performed based only on the design information for integration J0, but this is for ease of explanation, and other information described above, for example, security This does not prevent the total including the number of personnel (guardmen). The result integrated by the integration calculation unit 24 is output from the integration system 2 as integration result information J7 via the integration result output unit 25.

  In addition, the integration system 2 of the present embodiment has an integration design information acquisition unit 22 for acquiring the integration design information J0 separately from the design drawing information input unit 21, and the integration operation unit 24 The cost of the outer pipe work can be integrated using the design information for integration J0 acquired in the drawing information input unit 21 or the design information acquisition unit 22 for integration. In addition to the design drawing information input unit 21, an integration design information acquisition unit 22 for acquiring integration design information J0 is obtained by, for example, an operator reading information from a construction specification D1, a design drawing D2, or the like. It can be configured to input from the browser screen of the system 2.

  The integration design information J0 acquired by the design drawing information input unit 21 or the integration design information acquisition unit 22 is information for integration to be performed for the same construction, and therefore, excluding human errors and the like. It can be said that the information has the same content. An effective means for obtaining design information J0 for integration is when the construction company has not introduced the CAD system 1 capable of cooperating with this integration system 2 and the design drawing information J0 is effective. Design information acquisition unit 22. Accordingly, the calculation in the integration calculation unit 24 is basically performed in the same manner.

  In FIG. 3, a plurality of calculation units are provided inside the integration calculation unit 24 in order to facilitate the description and to clearly indicate that the integration is possible by obtaining the integration design information J0 from a plurality of systems. The structure is illustrated. That is, from the automatic integration calculation unit 24a that performs integration calculation based on the integration design information J0 automatically acquired from the design drawing information J1 stored in the electronic file, and documents such as the construction specification D1 and the design drawing D2. The general-purpose integration unit 24b that performs integration calculation based on the artificially acquired integration design information J0 is illustrated as a configuration having the integration calculation unit 24. Therefore, it is not necessary to limit the actual configuration to the present embodiment. Of course, it is also possible to have one calculation unit and select and calculate the input design information for integration J0.

  Moreover, in this embodiment, it is set as the structure also provided with the simple integrating | accumulating part 24c which integrates | accumulates based on the detailed design information of the said individual construction. For this simple integration, standard integration information J9, which is standard integration information, is used. The standard integration information J9 is stored in advance in the database 29b of the integration system 2. This is preferable because provisional integration before the design progresses and bidding conditions before bidding can be easily performed. The simple integration unit 24c is similar to the above, and may be configured such that only information used for integration can be selected.

  In addition, the integration system according to the present invention updates the acquired integration design information J0 by updating the acquired integration design information J0 to be new integration design information J0, and reflects the update from the updated integration design information J0. And an update information output unit 27 that outputs the designed drawing information J10. In actual outer pipe construction, the initial design content may be changed depending on the site situation after the construction is started. Even if a design change is added to the content of the construction, it is preferable in the management of the construction because the latest total can be performed as the construction progresses.

  In addition, since the update information output unit 27 that outputs the new design drawing information J10 reflecting the update is provided, the content that has been changed in accordance with the site situation is designed after the construction is actually started. It is also possible to return quickly to the drawing D2. For example, the design drawing information J10 reflecting the design change is input to the design drawing creation system 1, and the consistency between the design drawing D2 and the design drawing information J10 reflecting the design change is checked. The CAD system 1 can also be configured to clearly indicate the location or to automatically reflect the change contents in the design drawing D2. In this way, even if the design is changed in accordance with the progress of the construction, it can be reflected quickly and accurately in the design drawing D2. As a result, there is no inconsistency between the design drawing D2 of the construction and the construction performed on site at the acceptance inspection for inspecting the completion of the construction, which is preferable.

[Addition of design information for integration]
FIG. 4 is a diagram showing an example of a design drawing by the design drawing creation system of FIG. The design drawing D2 describes the design contents of the construction for extending the gas pipe to a newly built residential area (No. 1 to No. 3). A table 57 is provided at the upper left of the design drawing D2. In addition, the name of the construction and the construction location are described. As shown in FIG. 4, in this construction, a pipe 54 is newly laid on a road 53 branched from the existing road 52 on the road 51 that runs up and down on the drawing along a T-junction. From there, the gas pipe is extended to No. 1 to No. 3, which are residential areas under construction. The existing pipe 52 and the new pipe 54 are connected by a connecting portion (communication portion) 55, and the pipe 54 laid in this construction is not laid at a uniform depth, but has a different depth depending on the location. Will be laid. The piping 54 is provided with piping equipment 56 such as a valve for controlling the flow rate by shutting off and supplying the gas, and a water removing device for removing moisture due to water entering the gas pipe and saturated moisture in the gas. The

  The design drawing D2 includes, as information on the newly laid pipe 54, at least pipe construction information J3 which is information such as the construction type for the pipe 54 and the material and dimensions of the pipe 54, and the underground depth of the pipe 54. Length-specific extension information J4, pipe device information J5 which is information on the piping device 56 such as a governor, a valve and a water removal device installed in the pipe 54, and the connection form of the pipe 54 and the existing pipe 52 Is described and associated with the connection form information J6. In the form of Table 57, the construction No. The name of the construction, the construction location, etc. are also written. Is handled as construction identification information J2. As shown in FIG. 2, in accordance with the construction identification information J2, the pipe civil engineering information J3 is subordinated to the depth extension information J4 and the pipe equipment information J5, and then the pipe civil engineering information 3 and the connection form. Information J6 is managed. As described above, this does not mean that the information managed in association with the construction identification information J2 is only these, but is given as a representative example. Information such as the construction number, construction name, construction location, etc. described above is also managed in association with the construction identification information J2.

  FIG. 5 is a diagram for explaining a method of inputting design information for integration into the design drawing of FIG. FIG. 5 shows a screen image displayed on a monitor connected to a computer constituting the CAD system 1 for drawing the design drawing D2 shown in FIG. The window 60 displayed on the screen has a menu bar 61. Here, as an example, an electronic file is called from a storage medium such as a hard disk to the CAD system 1 or saved on the contrary. “Help” for driving a manual or a search system, editing of input of design information for integration J0, etc., association of various information constituting the design information for integration J0, output of design drawing information J1, etc. ] Items are shown.

  When one is selected from the menu bar 61, a pull-down menu 62 appears below the selected menu bar 61 item. Here, for example, when “integration support tool” in the menu bar 61 is selected, various information constituting the design drawing information J1 as shown in FIG. Accumulation system such as "extension drawing by depth" and "extension correction by depth" for correction, and "grouping" for associating depth extension information J4 and piping equipment information J5 with piping civil engineering information J3 An item for operating the design drawing information J1 appears in order to cooperate with the program 2.

When a desired menu is selected from the pull-down menu 62, an operation corresponding to the selected menu can be performed. FIG. 5 shows an example in which the “extension drawing by depth” menu is selected and a new window 63 for operation is displayed by selecting this menu. Here, it is associated with the pipe 54 as extension information J4 by depth, and is also visually described on the drawing.
“1-General-1.20-75-Fushigoko-O"
The example which inputs is shown. Here, the above description is separated by a hyphen (-),
1: Span No.
General: Construction method sign,
1.20: Depth to be piped (unit: meter),
75: Total length of piping (unit: meter),
Fushikoshi Elementary School
0: Has the quantity of atypical tubes. These are described by selecting a line segment representing the pipe 54 on the drawing (layer selection) and inputting each of the above information in association with this, and this content is described by extension information J4 by depth. It becomes. As shown in FIG. 5, depending on the type of information, there are those that input numerical values such as an input frame 64 and items that are selected from preset items such as a list selection frame 65.

  Here, the “span No.” is an identification number as a serial number representing the pipes 54 laid with different depths for each section, and is automatically assigned by the CAD system 1. The “construction method signature” is input by selecting an item from the pull-down menu of the list selection frame 65. The items include a general method with normal excavation, a flow molding method with a non-open cutting method, and the like. In this embodiment, an example in which “general” is selected is shown. “Pipe depth” and “Pipe length” are numerically input in the input frame 64 in units of meters. In the present embodiment, an example in which piping is performed over 75 meters at a depth of 1.2 meters is shown. The “Busetsu / overpass sign” is input by selecting an item in the list selection frame 65, for example, when piping is required across a river or the like. The items include “None” indicating that there is no crossing, “overpass”, and “Fushigoe”. In this embodiment, “Fushigoe Small” is selected. The “number of atypical pipes” is the number of atypical pipes (pipes having different shapes) existing in a designated pipe section, and is numerically input from the input frame 64. In the present embodiment, zero is input assuming that the atypical tube is not used.

  As described above, if the input is performed separately for the numerical value input and the item selection item, the term meaning the item does not differ depending on the designer who inputs. Therefore, even when the integration is performed using the information input in the design drawing, there is no doubt and the configuration is preferable. In addition, there is also a method in which a term meaning an item is defined in a manual or the like and entered by referring to it only for preventing doubt. However, it is not realistic to make everybody follow a complicated manual. Therefore, it is an advantage of this embodiment that all people can input without feeling bothered in the same way.

Here, the contents of other information will be briefly described. The piping civil information J3 is information indicating the type of construction, the type of piping, the specifications of piping, and the like. As illustrated in FIGS. 3 to 4, the design drawing D2 as piping civil engineering information J3 includes:
"Laying PE 150φ x 120m (private land, As)"
It is described. This indicates that the construction type is “laying”, the piping type is “PE (polyethylene) pipe”, the diameter is 150 mm, and the extension distance is 120 meters. Other types of construction include “removal” and “restoration” from temporary pavement immediately after outer pipe construction to main pavement, and types of piping include “steel pipe” and “cast iron pipe”. Note that the description in parentheses is a remark, and although not used for direct integration, useful information is described as a drawing. Here, it is shown that the construction target land is private land and is paved with asphalt (As).

  When the piping civil engineering information J3 is input, it is preferable to input it separately for numerical input and for selecting an item because the above-described effects can be obtained. That is, the type of construction and the type of piping can be selected, and the diameter and extension distance of the piping can be input numerically. Here, the extension distance of the pipe is a non-continuous numerical value that varies depending on the construction site, but the diameter of the pipe depends on the diameter of the existing pipe and is a stepwise numerical value. Depending on the case, there is a possibility that the types depending on the diameter of the pipes to be used are gathered in consideration of purchasing efficiency even if they are produced. Therefore, it is preferable that the diameter of the pipe is also selective because it is possible to eliminate the designation of the diameter of the pipe that cannot be used according to the purchasing policy or the diameter of the pipe that is not produced. On the other hand, it is useful to use a pull-down menu as exemplified in the list selection frame 65 of FIG. 5 for the type of construction, the type of piping, etc., but it is useful to use a pull-down menu with many types of pipe diameters. Adoption of the menu may cause troublesomeness. In such a case, the pipe diameter may be input as a numerical value, and a check function may be provided in the CAD system 1 so that inappropriate designation can be eliminated.

Next, the connection form information J6 will be described. As described above, the connection form information J6 indicates that the existing conduit (pipe) through which the gas has already been communicated after the new conduit (pipe) has been laid and it has been confirmed that there is no abnormality by performing a pressure resistance or airtight test. This is information related to the work called liaison work or knot work. In the design drawing D2, as shown in FIG.
"Chief communication (cast steel)"
It is described. This is input by item selection together with the description in parentheses. Here, it is shown that it is connected to a T (cylinder) character. Other options include “direct communication” and “live tube branching”. Further, the connection form information J6 further includes information such as the size of the existing pipe and the new pipe, the material of the connection location, and the like as attribute information.

  The piping equipment information J5 is information that the equipment symbol (symbol) of the CAD system 1 has as an attribute, and is information stored in a so-called library provided in the CAD system 1.

  As described above, each piece of information is input, and the extension information J4 by depth and the piping equipment information J5 are associated with the piping civil engineering information J3 by the grouping function of the CAD system 1. That is, the extension information J4 by depth and the piping equipment information J5 are information subordinate to the piping civil engineering information J3. Next, the pipe civil engineering information J3 and the connection form information J6 are associated with the construction identification information J2, and the design information for integration is centrally managed.

  Here, when the grouping function is activated, for example, whether the extension information by depth J4 and the piping equipment information J5 are subordinate to the piping civil engineering information J3, so that there is no contradiction, or the input information is correct. It is advisable that the above check function is used to check whether there is any missing item. Of course, the same applies to the case where the pipe civil engineering information J3 and the connection form information J6 are associated with the construction identification information J2. Furthermore, it is preferable to use this check function when the CAD system 1 outputs these associated information as design drawing information J1.

[Construction management system]
FIG. 6 is a diagram for explaining the flow from the construction plan to acceptance inspection. When the outer pipe construction is drafted by the construction ordering business operator, a construction specification D1 is created. Then, construction design is performed by a construction company participating in the bidding based on the construction specification D1, and a design drawing D2 is created as a result. The construction ordering company estimates (accumulates) the construction based on the information described in the construction specification D1 and the design drawing D2, and constructs the contractor based on the accumulated result information J7 obtained from the result of the accumulation. The company is decided and the construction is ordered. When construction is carried out by a construction company, inconsistencies often occur between the actual construction site conditions and the design drawing D2. And when inconsistency arises, the correction design drawing D3 is produced, modifying the design drawing D2 suitably, and construction is advanced. At that time, if the contents of the design change, that is, update information is notified to the construction ordering company, the construction ordering company will re-estimate (re-accumulate) and grasp the difference from the initial estimate to manage the construction. Do. When the construction is completed, the modified design drawing D3 in which all the changed items are described and the state of the construction site are identified, and the construction is accepted.

  FIG. 7 is a schematic diagram showing an example of extending the construction management system of FIG. As described with reference to FIG. 6 above, there are a plurality of construction companies, and they receive orders from construction ordering companies by so-called bidding and undertake construction work. Therefore, the construction management system of the present embodiment has a plurality of CAD systems 1 as shown in FIGS. 1 and 7 for the construction contractor to design the construction based on the construction specification D1 of the construction ordering company. ing. The construction ordering company has one integration system 2 that performs integration using the design drawing information J1 output from these CAD systems 1. That is, the construction management system according to the present embodiment includes the CAD system 1 for each individual construction company, and the integration system 2 for the construction ordering company. These systems are connected by the network system 3. In addition, when the integration system 3 is constructed by a distributed system or the like, there may be a plurality of integration systems 3, so that the integration system 3 does not have to be one as shown in the present embodiment.

  The integration result information J2 output from the integration system 2 is stored in the database 6 via the network system 5 different from the network system 3 described above, and is used in the ordering system 7, for example. The ordering system 7 performs an ordering process such as determining a construction company that orders the construction from the integration result information J2 and the like, and issuing an ordering slip.

  In the present embodiment, the network system 3 is constituted by the Internet, for example, and the network system 5 is constituted by an intranet, for example. This is because a network before integration that needs to be connected to a plurality of construction companies is constructed by a public system, and a network after integration including information that is not disclosed, such as integration result information J7, is a non-public system. This makes it possible to refer to it only within the construction ordering company. As shown in FIG. 7, the in-house terminal 8 of the construction ordering company, the CAD system of the in-house design department, and the like are included in a network system 5 constructed by an intranet. Of course, the CAD system 1 of the design department of the construction ordering company may be provided in the network system 3 constructed on the Internet.

  FIG. 7 shows an example in which the network systems 3 and 5 are constructed on the Internet and an intranet, respectively, in order to make it easy to understand the distinction between public and private. The embodiment is not limited to this, but the database that can be viewed is limited by security settings, etc., and the accumulated result information J2 cannot be referred to. May be connected.

  As described above, the present invention provides a design drawing creation system that can effectively extract information necessary for integration from a design drawing according to the present invention, and integration that can be efficiently integrated using this drawing creation system. In addition to providing a system, it is possible to provide a construction management system that has these systems and manages construction well.
