Description

The present invention relates to a building system.

When constructing a building, quantity picking is carried out to calculate the quantity of building materials such as base materials specified in the design documents from the design materials such as drawings of the design documents. Based on the quantity of building materials obtained by carrying out quantity picking, an estimate of building materials used for construction and ordering work are carried out.

This quantity picking is a work that requires a lot of time and labor in the construction work of a building, and is a factor that increases the burden on the worker such as an increase in the work man-hours of the worker and an increase in overtime hours. Therefore, it is required to reduce the work of picking up the quantity.

In addition, at the actual construction site, there are construction errors including the unevenness of the skeleton with respect to the drawings, etc., and the building materials cannot be installed as they are at the actual construction site. Therefore, it is necessary to measure the dimensions of the construction site and then process the building materials to match the dimensions. This work also causes an increase in the work man-hours of the worker, which increases the burden on the worker.

By the way, CAD is used for building design, and in recent years, building design has been performed using building information modeling (hereinafter referred to as BIM) (for example, Patent Document 1). 2, 2nd grade).

In BIM, a building (BIM model) can be reproduced on a computer by combining parts (BIM parts) of a plurality of structures. BIM parts and BIM models have various attribute information in addition to three-dimensional shape information. For example, attribute information such as the name / area of a room, specifications / performance of materials / members, and finish is included in BIM parts and BIM models. By using the attribute information of the BIM parts and the BIM model, there is a possibility that the work of picking up the quantity can be reduced.

However, at present, even when designing using BIM, the work of picking up the quantity using the attribute information of the BIM parts and the BIM model is not sufficiently performed, and even at present, the worker spends a lot of time on the quantity. We are picking up.

In addition, since construction errors naturally occur even when designing using BIM, it is not possible to reduce the work of processing building materials after measuring the dimensions at the construction site.

<Explanation of building material calculation system 20 and building material calculation system 50>
Hereinafter, the building material calculation system 20 and the building material calculation system 50 will be described in detail.

<Building material calculation system 20>
As shown in FIG. 1, the building material calculation system 20 includes a quantity calculation unit 23.

The quantity calculation unit 23 has a function of calculating the quantity of the interior material required when constructing the interior material on each part of the building model M. Information about the interior material to be used may be included in the BIM information of the structure stored in the BIM information storage unit 11, and may be included in the building material calculation system 20 in each part of the building model M. It may have a function of inputting an interior material to be used.

The quantity calculation unit 23 has quantity information of building materials used for each part of the building model M. This quantity information stores information on the quantity of interior materials for each part of the building model M for each interior material used in each part.

When there is a possibility that the same type of interior material having a different shape or the like is used for each part, information on the quantity is stored for each interior material having a different shape or the like. In the following, the term "interior material" includes not only different types of interior materials but also interior materials of the same type having different shapes and the like.

In this quantity information, for example, the shape of each part of the building model is related to the interior material used in the shape and the quantity thereof. The quantity of the interior material in this quantity information is a quantity obtained in advance in an actual building having a predetermined shape and dimensions. This quantity is based on, for example, the quantity of interior materials calculated in advance by the operator based on drawings, etc. for walls with a certain value such as area, distance between pillars, and floor-to-ceiling height, and past construction results. It is the quantity of interior materials obtained. The quantity information includes various dimensions of structures such as walls and ceilings (in the case of walls, the area, the distance between columns, and the height from the floor to the ceiling), and each interior of the structure having those dimensions. The quantity of timber is associated and stored.

Using this quantity information, the quantity calculation unit 23 calculates the quantity of the interior material by the calculation process carried out in the following procedure (step) (see FIG. 2).

<Interior material calculation procedure>
First, the information of the building model M stored in the BIM system 10 is supplied to the quantity calculation unit 23. Then, the quantity calculation unit 23 implements a step of acquiring shape information regarding the shape of each part of the building model M from the information of the building model M. For example, in the case of a ceiling, the quantity calculation unit 23 acquires information such as the area and the length of each side (distance between walls). If it is a wall, the quantity calculation unit 23 acquires information such as its area, its height (distance from the floor to the ceiling), and its width (distance between pillars).

When the building material calculation system 50 is provided, in this step, the site information is acquired from the site information storage unit 52 of the building material calculation system 50, and the shape information of the construction site included in the site information is included. May be used in place of the shape information of the building model M.

When the shape information of each part is acquired from the information of the building model M, the quantity calculation unit 23 applies the interior material to each part of the building model M by using the shape information and the quantity information of the interior material to be used. Perform the steps to calculate the quantity of interior material required for placement. For example, let X be the area of the wall included in the shape information, and let S be the quantity of the base material to be installed per unit area Y of the wall included in the quantity information of the base material to be used. In this case, the quantity calculation unit 23 can calculate the quantity of the base material used for the wall based on the formula of X / Y × S.

As described above, in the building system 1 of the present embodiment, if the building model M is created by the BIM system 10, the type and quantity of building materials such as interior materials required for the construction of each part of the building model M Can be decided. Therefore, it is possible to reduce the time and effort required to calculate the quantity of building materials such as interior materials used for construction.

Moreover, since the dimensions and shapes of each part of the building model M are grasped by using the information of the building model M, the accuracy of the dimensions and shapes of each part which is the base for calculating the quantity is improved. Then, since the calculation accuracy of the quantity of building materials such as interior materials can be increased, it is not necessary to order an extra amount of interior materials, and the construction cost can be suppressed.

As described above, when the building material calculation system 50 forms the processing information of the building material to be processed, the quantity calculation unit 23 acquires the processing information from the shape calculation unit 53 of the building material calculation system 50. You may. In this case, since the processing information includes the quantity of the building material to be processed and the interior material thereof, the quantity of the building material to be processed is supplied from the shape calculation unit 53 of the building material calculation system 50. May be used as it is. In this case, for the other building materials, the quantity of the building materials is calculated by the method described above, but when the information of the building materials to be processed at that time is used, the processing information may be used. For example, when the building material to be processed is a base material, if the shape of the base material included in the processing information changes from the shape of the base material obtained from the BIM information or the information input to the building material calculation system 20, the board The quantity of building materials such as materials and auxiliary materials used may change. In this case, if the quantity information used by the quantity calculation unit 23 to calculate the quantity of the building material is changed by using the information on the shape of the base material included in the processing information, the quantity of the board material, the auxiliary material, etc. The calculation accuracy of can be increased and waste can be eliminated.

<Modification based on enforcement procedures and building standards>
In the above example, the case where the quantity calculation unit 23 calculates the quantity of building materials when normal construction is performed has been described. On the other hand, when the construction site adopts a special enforcement procedure or building standard, the quantity calculated by the quantity calculation unit 23 may not be appropriate. Then, the worker may correct the quantity of the building material calculated by the quantity calculation unit 23 in consideration of the building standard and the like. In this case, the building material calculation system 20 is provided with an input function for inputting the quantity of the building material modified by the worker, and the numerical value in which the quantity of the building material calculated by the quantity calculation unit 23 by the input function is input. It is desirable to have a function to replace with.

In addition, the quantity information may store the same building material or the quantity corresponding to the enforcement procedure and the building standard. In this case, it is desirable that the building material calculation system 20 is provided with a construction information storage unit 22 that stores the enforcement procedure and the building standard. Then, the quantity calculation unit 23 can calculate the quantity of the building material in consideration of the enforcement procedure and the building standard.

In this case, the construction information storage unit 22 stores construction information regarding construction standards, construction procedures, and the like to be observed when the interior material is constructed at each part of the building model M. Further, the construction information storage unit 22 can supply the construction information to the quantity calculation unit 23 based on the command from the quantity calculation unit 23.

When such a construction information storage unit 22 is provided, the quantity calculation unit 23 calculates the quantity of the interior material by the following procedure (see FIG. 3).

First, the quantity calculation unit 23 carries out a step of acquiring shape information regarding the shape of each part of the building model M from the information of the building model M, as in the case where the construction information storage unit 22 is not provided.

Next, the quantity calculation unit 23 acquires information on the enforcement procedure to be adopted and the building standard from the information on each part of the building model M.

Then, before carrying out the step of calculating the quantity, the quantity calculation unit 23 determines the enforcement procedure and the building standard corresponding to the information of the enforcement procedure and the building standard to be adopted included in the information of each part of the building model M. To get. For example, when constructing the base material used for the wall, the quantity calculation unit 23 acquires information on the procedure for constructing the base material. Further, when there is a building standard or the like related to the construction of the base material, the quantity calculation unit 23 acquires information on the building standard from the construction information storage unit 22.

After that, the quantity calculation unit 23 acquires the quantity information associated with the enforcement procedure and the building standard acquired from the construction information storage unit 22 as the quantity information of the base material, and uses this quantity information with the shape information. To carry out the step of calculating the quantity of interior materials.

Then, since the quantity of the interior material can be calculated in consideration of the enforcement procedure and the building standard, the accuracy of calculating the quantity of the interior material can be improved and waste can be eliminated.

Even if the quantity calculation unit 23 can acquire the quantity information associated with the enforcement procedure and the building standard only by the information of the enforcement procedure and the building standard included in the information of each part of the building model M. good. In this case, even if the construction information storage unit 22 is not provided, the quantity of the interior material associated with the enforcement procedure and the building standard can be calculated as in the case where the construction information storage unit 22 is provided.

<Input unit 24>
In the building system 1 of the present embodiment, the quantity of all interior materials used for each part may be calculated for all parts of the building model M, but a specific part or a specific part may be calculated. The quantity may be calculated only for the interior material. Then, since it is only necessary to calculate the quantity of the interior material of the required portion and the quantity of the required interior material, the time for the quantity calculation unit 23 to calculate the quantity of the interior material can be reduced.

For example, an input unit 24 for inputting a part for calculating the quantity and an interior material is provided (see FIG. 1). Then, if only the shape information of the specific part is extracted from the information of the building model M based on the information about the part input from the input unit 24 and the calculation process is performed only for that part, the quantity of the interior material can be obtained. The calculation time can be reduced.

Further, if the calculation process is performed only for a specific interior material based on the information on the interior material input from the input unit 24, the time for calculating the quantity of the interior material can be reduced.

A known input device can be used for the input unit 24. For example, a keyboard, a barcode reader, or the like can be used.

<Ordering system>

The ordering information forming unit 41 has a function of generating ordering information in which the quantity of the interior material and the information about the interior material are associated with each other. The ordering information is recorded in association with, for example, the quantity of the interior material, the model number of the interior material, the manufacturer of the interior material, and the like. In addition, information on the supplier who orders the interior material may also be recorded in association with the information.

The order information generated by the order information forming unit 41 is supplied to the transmitting unit 42. The transmission unit 42 has a function of transmitting order information to a predetermined ordering party by using e-mail, fax, or the like.

For example, the ordering party to which the ordering information is transmitted is stored in the transmission unit 42, and the ordering party and the interior material are associated with each other and stored as the ordering party information. Then, based on the interior material information included in the ordering information, the transmission unit 42 can acquire the ordering party from the ordering party information and transmit the ordering information to the ordering party.

If the ordering information stores the ordering party information, the transmission unit 42 acquires the ordering party information from the ordering information and transmits the ordering information to the ordering party based on the acquired ordering party information. can do.

Further, the ordering unit 40 may include a transmission input unit 43 for inputting information on the ordering party to which the ordering information is transmitted when the ordering information is acquired. In this case, the information of the supplier who places an order for the first time can be easily input, and the change operation becomes easy even when changing the supplier stored in the order information of the transmission unit 42.

When changing only the supplier of a specific interior material, the information of the interior material to be changed and the supplier to be changed may be input. Similarly, when changing the supplier of the interior material in a specific part of the building model, the specific part to be changed and the supplier to be changed may be input in the building model.

<Order Department 100>
The order receiving unit 100 is provided at the ordering party, and has a receiving unit 101 and an order information forming unit 102.

For example, in the case of a base material used for a wall or a board used for a ceiling, the processing information calculation unit 53 such as the thickness, width, and length of the board is acquired. If it is a base material used for a wall, the processing information calculation unit 53 acquires information such as its thickness, width, and length.

When this information is acquired, the processing information calculation unit 53 compares the shape of the construction site with the shape of the interior material by using the shape information and the dimensional information of the construction site, and is suitable for the construction site. Perform the step of calculating the shape of the interior material.

For example, as shown in FIG. 6A, the construction site is the wall W, the wall W included in the shape information of the construction site is a horizontally long rectangle, and its width is L1. In FIG. 6A, the upper end edge of the wall W is extremely inclined. The base material B included in the dimensional information is a vertically long rectangle, and its width is L2. In this case, the processing information calculation unit 53 first calculates the quantity of the base material B required by L1 / L2. In FIG. 6A, the number of base materials B is four. Next, the processing information calculation unit 53 forms a state in which the base materials B are sequentially arranged and installed from one end of the wall W (the left end in FIG. 6A), and the shapes of the base materials B1 to B4 and the wall W are formed. Compare with. That is, the left edge Wb of the base material B1 and the left edge of the wall W are matched, and the lower end edges of the base materials B1 to B4 are matched with the lower edge of the wall W, so that the base materials B1 to B4 are formed. The shape of the wall W and the shapes of the base materials B1 to B4 are compared with each other in a state of being arranged along the wall W. Then, the upper end edges of the base materials B1 to B4 are in a state of protruding from the upper end edge Wr of the wall W, and the protruding portion has a substantially triangular shape. Further, the base material B4 has a state in which the right end portion thereof protrudes from the right end edge Wa of the wall W. In such a case, the processing information calculation unit 53 stores information necessary for processing each base material B1 to B4 into a shape matching the shape of the wall W as processing information. For example, the position (intersection) where the left and right side edges of the base materials B1 to B4 intersect with the upper end edge Wr of the wall W is calculated, and the length from the lower end edge to the intersection is set to the left and right of each base material B1 to B4. It is calculated as the height of the side edge of and stored as processing information. Further, the processing information calculation unit 53 calculates the length from the left edge of the base material B4 to the right edge of the wall W as the width of the base material B4 and stores it as processing information.

As described above, in the building system 1 of the present embodiment, the processing information calculation system 50 creates the processing information of the building material such as the interior material. Therefore, if the site information regarding the construction site is created, the building material is calculated. The system 50 can calculate the processing information for processing the building material according to the situation of the construction site. Then, if the building material is processed in advance based on the processing information, the processing work at the construction site can be reduced.

When arranging the base materials B along the wall W, the base material B as a reference may be arranged at a reference position such as the center of the wall W, and then the other base materials B may be arranged. In this case, the ends of the base material B (the left end if it is the left end and the right end if it is the right end) located at both left and right ends protrude from both ends of the wall W. Therefore, the width of the base material B located at both left and right ends is calculated and stored as processing information.

Further, when the ends of the base material B project from both ends of the wall W, the processing information calculation unit 53 may have a function of changing the base material B to be used. That is, a single base material B capable of preventing the ends from protruding from both ends of the wall W, or a plurality of different shapes capable of preventing the ends from protruding from both ends of the wall W. The processing information calculation unit 53 may acquire the information of the base material B of the above from the material information storage unit 51.

Similarly, even when the upper end edge of the base material B does not reach the upper end edge Wr of the wall W, the upper end edge can be in a state of protruding from the upper end edge of the wall W (or at the same position). The processing information calculation unit 53 may acquire the information of the base material B from the material information storage unit 51.

In addition, the site information may also include dimensional information regarding the dimensions measured at the construction site. For example, if the dimensional information is stored in association with the image information of the construction site, the dimensions of each part obtained by the image analysis can be compared with the dimensional information, so that the shape of the construction site can be reproduced more accurately.
The site information may include only dimensional information without including image information.

It may be difficult for workers to directly measure the dimensions of seismic retrofitting points such as the ceiling, underfloor, and walls, or to perform construction that meets the specified standards. For example, in the attic of a suspended ceiling, there are various pipes and structures that indicate the suspended ceiling, and there are many cases where there is no space in which seismic structural materials can be freely installed. In this case, as the seismic structural material, it is necessary to select a seismic structural material capable of exerting a desired seismic strength, and select a seismic structural material that can be actually installed.

In the seismic structure examination system 70, the seismic reinforcement model design unit 72 makes a building based on the information of the seismic reinforcement part in the building model M and the information of the seismic structural material stored in the seismic structural material storage unit 71. It has the function of forming a seismic reinforcement model in which seismic structural materials are arranged at the locations of seismic reinforcement in model M.

The seismic structural material storage unit 71 stores information on seismic structural materials. Information on seismic structural materials is, for example, information on seismic strength, applicable locations, dimensions, and shapes of seismic structural materials, and this information can be used to form 3D models of seismic structural materials.

The seismic retrofitting model design unit 72 displays a 3D model of the part to be examined for seismic retrofitting in the building based on the information of the building model M stored in the BIM system 10, and the seismic retrofitting structural material is displayed on this 3D model. The 3D model is arranged and displayed. That is, the seismic retrofitting model design unit 72 inputs the part of the building for which the worker considers seismic retrofitting, displays the 3D model of the part, and the worker selects the seismic structural material and the part of the building. It has a function to lay out a 3D model of seismic retrofitting material on the 3D model of. The seismic retrofit model design unit 72 also has a function of forming and storing a seismic retrofit model in which seismic structural materials are arranged.

As described above, in the seismic structure examination system 70, a 3D model of the seismic structural material can be arranged on the 3D model of the part of the building to be examined for seismic reinforcement. Then, even if various members (pipes, structural materials, etc.) are present at the site to be examined for seismic retrofitting, the arrangement of the seismic structural materials can be examined so as not to interfere with these members. Therefore, seismic retrofitting can be considered even in places where it is difficult for workers to directly measure dimensions or perform construction that meets the specified standards, such as inside suspended ceilings or under the floor. It is possible to design an appropriate seismic retrofit model.

The building system of the present invention is suitable for a system for picking up numerical values of building materials used for interiors of buildings such as reinforced concrete (RC) and steel (S) and designing pre-processing. ..
