<P>PROBLEM TO BE SOLVED: To calculate beam strength to a predetermined accuracy through visual inspection alone even if the internal structure of a building is unknown in the absence of the drawing of the building. <P>SOLUTION: When expansion or reconstruction of an existing building is requested, the loads of beams to be provided at designated portions are calculated. The kind of tree and the size of the beams are determined based on the result. An approximate plan of the building and data about wall position information 15, wall kind information 17, floor position information 16, floor overlap information 18 and the like are inputted in advance. Once the positions of the beams are designated, floors whose loads the beams support are selected. Further, the weight of a portion of a rectangular floor one side of which is the beam is calculated using the concept of "control width." The weight is the load shared. For all the floors one side of which is the beam, the loads shared are calculated and added together to calculate the total loads applied to the beams. The beams sized to withstand the loads are selected to complete processes. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a building renovation structure calculation system suitable for rough design and cost estimation calculation in renovation work for buildings such as wooden houses.

For new houses in recent years, earthquake resistance standards based on earthquake experience have been applied. However, many old houses do not meet that standard. Therefore, during the renovation design of the house, the renovation work is being carried out to satisfy the seismic standards by calculating the reinforcement of existing beams at the same time as designing the renovation part. (See Patent Document 1) (See Patent Document 2)
JP2001-107458 JP-A-11-303114

By the way, the above technique has the following problems to be solved.
Before the extension / reconstruction design, for example, it is determined that a predetermined reinforcement is required for the current beam, or that a certain beam can be removed and expanded / reconstructed. In addition, a plan will be made to newly install a beam of sufficient strength at the boundary between the existing part and the extension / reconstruction part. At this time, if the design drawings of the building are stored, a specific detailed design and cost estimation calculation can be performed on the desk. However, many old houses do not store design drawings. Therefore, unless the walls and ceiling are broken, the existing beam thickness and connection structure are unknown, and accurate estimation calculation is impossible. Of course, a part of the building cannot be destroyed when calculating the estimated cost of extension and renovation. Therefore, the design was made by predicting the internal structure by a skilled construction engineer. If this prediction is not met, there is a problem that a large error is generated in the estimation calculation result, and the design or estimation needs to be significantly changed.

  The present invention has been made to solve the above-mentioned problems, and it is possible to calculate the cost of repair work speedily with an error within an allowable range without disassembling the repair design part without a design drawing.

  The system of the present invention calculates the load load of a beam to be provided at a designated place when an extension or renovation of an existing building is requested. From the results, the tree species and dimensions of the beam are obtained. This calculation is executed by a computer program. A rough floor plan of the building and data such as wall position and wall type, floor position and floor weight are input in advance. When the position of a beam is specified, the floor on which the beam supports the load is selected. Furthermore, the weight of a part of the rectangular floor with the beam as one side is calculated using the concept of the dominant width. This weight is a shared load. When the shared load is obtained and accumulated for all the floors with the beam as one side, the total load applied to the beam is calculated. Since the building has a wooden frame structure, the processing ends when a beam having a size capable of withstanding this load is selected. Even if there is no drawing of the building and the internal structure is unknown, the calculation results can be output within a certain error range. Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

FIG. 1 is an explanatory diagram showing an example of an operation screen of the system of the present invention. FIG. 2 is a block diagram showing a specific example of the entire system of the present invention.
The illustrated system is controlled by a computer. This computer comprises a personal computer or a workstation. As shown in FIG. 2, the computer includes a storage device 3 and an arithmetic processing device 5. The storage device 3 and the arithmetic processing device 5 may be built in the computer or externally attached. The computer includes a display 1, a mouse 2, and the like. Since all of these hardware can be used, illustration and specific description of each function are omitted. The display 1 shown in the figure is used as display means, and the mouse 2 is used as data input means.

  As shown in FIG. 1, an operation screen 12 for creating floor plan data 30 is displayed on the display 1. A grid 13 is displayed in the operation screen 12. When two arbitrary lattice points 14 are designated using the mouse 2, one line segment 21 can be drawn. In order to create the main part of the floor plan data 30, all the line segments 21 representing the walls of the building may be input. In order to carry out the present invention, at least information for clarifying the position of the bearing wall is input.

  After inputting all the necessary wall position information 15, the beam position designation line 22 designates the position of the beam to be added or reinforced at the time of extension and reconstruction. For example, the load of the floor block 23 or the floor block 24 is applied to the beam. When the beam position designation line 22 is designated with the cursor 25, a window 26 is displayed. When the floor weight information 18 is input to the window 26, a predetermined calculation process is executed and a beam selection result 27 is displayed. In order to execute the above processing, the system stores information as shown in FIG. 2 in the storage device 3, and the arithmetic processing device 5 includes a computer program for executing predetermined arithmetic processing.

  The storage device 3 stores floor plan data 30 representing a schematic floor plan of a building. The floor plan data 30 includes line segment data 32 and attribute data 34. The line segment data 32 represents wall position information 15 and floor position information 16. Here, if only the bearing wall is input, the wall type information 17 is automatically included. When inputting a miscellaneous wall at the same time, information for distinguishing the bearing wall and the miscellaneous wall may be input. Further, the wall type may be expressed by inputting a wall magnification.

  The grid 13 is set to a unit length interval such that the interval is 30 cm or 50 cm, for example. In the graphic drawing application program, a snap effect is applied to the grid 13 to forcibly superimpose both ends of the line segment 21 to be drawn on the grid points 14. Therefore, a line segment that is an integral multiple of the unit length can be easily input into the operation screen 12. At the same time, floor plan data 30 combining the line segments 21 can be generated.

  If the interval between the grids 13 is appropriately selected, the floor plan drawn by this method is sufficiently accurate to the extent calculation for extension and reconstruction. In order to use the floor plan data 30 for the extension and renovation design, more detailed data may be input. However, since only the above-described information is necessary for the present invention, further explanation is omitted. The portion surrounded by the line segment 21 becomes a floor in principle, but it may be a space or a veranda surrounded by an atrium or an outer wall, and is specified by the floor position information 16. The broken line indicated by the mark X shown in FIG. The attribute data 34 included in the floor plan data 30 is information including coordinate values of the grid 13 and floor position information 16.

  In addition to this, the storage device 3 stores a floor area 55, a control ratio 56, a floor weight 57, a shared load 58, a cumulative value 59, and a beam selection table 60. These data are generated or acquired in the course of arithmetic processing, and are sequentially stored in the storage device 3. The beam selection table 60 is a calculation table that outputs information indicating the dimensions and dimensions of the corresponding beam when the accumulated value 59 is input.

The arithmetic processing unit 5 has a specification unit 40, a drawing control unit 41, a display control unit 42, an information acquisition unit 43, a beam specification unit 44, a floor detection unit 45, a load calculation unit 46, a beam selection unit 47, and the like. A computer program with the above functions is installed.
The designation means 40 designates a line segment 21 whose end point is the grid point 14 on the grid 13.

  The drawing control means 41 draws the line segment 21 specified by the specifying means 40 as a building wall on the operation screen 12 and stores the line segment data 32 for drawing the line segment 21 in the storage device 3. The storage device 3 has a function of storing an assembly of line segments 21 drawn on the operation screen 12 as a schematic floor plan of a building. The display control means 42 has a function of displaying on the operation screen 12 a window 26 including information on the basis of load calculation and the tree type and dimensions of the beam to be subjected to strength calculation. Note that the designation unit 40, the drawing control unit 41, and the display control unit 42 can use the functions of the existing operating system as they are.

  The information acquisition means 43 has a function of acquiring the wall position information 15, the wall type information 17, the floor position information 16 of the floor supported by the wall, and the floor weight information 18 input using the window 26. Have. The beam designating unit 44 has a function of displaying 22 for designating the position of the beam to be subjected to strength calculation in the schematic floor plan displayed on the display unit 11 and acquiring the position information. The floor detection means 45 detects the floor supported by the beam designated by the beam position designation line 22, and uses the wall position information 15, the wall type information 17, and the floor position information 16 to identify the boundary of the beam. It has a function of detecting a part of a floor supported by a floor block surrounded by a plurality of bearing walls.

  The load calculation means 46 calculates a shared load for supporting the floor of the beam and a load on the floor of the beam for a floor having the beam as a part of the boundary and satisfying a predetermined condition. Thus, the accumulated value 59 is obtained. The beam selection unit 47 refers to the beam selection table 60 on the basis of the accumulated value 59 calculated by the load calculation unit 46, selects the tree type and size of the beam to be subjected to strength calculation, and displays and outputs the result. Has function.

FIG. 3 is an explanatory diagram showing a calculation processing operation of the load detection means.
A beam 75 in the figure is a beam to be subjected to calculation processing. The beam 75 supports the floor 61 and the floor 62. These floors 61 and 62 have a beam 75 as a part of the boundary. The determination of whether or not both of these floors 61 and 62 satisfy a predetermined condition will be described later with reference to FIG. Here, the load calculation is performed assuming that both floors satisfy a predetermined condition. In the calculation method of the present invention, for example, it is assumed that the total load of the floor 61 is supported by the beams 71 and 75 facing each other. Ignore the sharing of other beams. If the beam 71 and the beam 75 share the load equally, the beam 75 is calculated to support half of the load on the floor 61. The result is a shared load 58. The same calculation is performed for the floor 62 to determine the shared load. When the obtained results are accumulated, a cumulative value 59 is obtained. Since the beam 75 supports the half width of the floors 61 and 62, the width between the boundary line 91 and the boundary line 92 in the figure is referred to as a control width B.

  Note that the load applied to the beam may include a load on the floor in addition to the floor. The load on the floor of the beam is a non-negligible load arranged on the floor, for example, the weight of a bookshelf built on the floor or a specific wall directly above the beam. In the wooden frame construction method, the load of the structure is almost supported by the columns. Therefore, for example, it is sufficient to calculate the strength of the beam provided under the second floor as it supports only the load of the second floor and the non-negligible heavy load on the floor. Further, by clarifying in this way, it becomes possible to automatically calculate the tree species and dimensions of the beam within an error range below a certain level.

FIG. 4 is an explanatory diagram of the predetermined condition.
It is assumed that the beam position designation line 100 is designated in the floor plan shown in FIG. Here, the floor block 101 is considered. The floor block 101 is rectangular. The length of one side is A, and the length of the other side is B. Since A is longer than B, the designated beam constitutes one of the long sides of the floor block 101. At this time, even if it is assumed that all the loads of the floor block 101 are supported by a pair of beams designated by the beam position designation line 100 and the beams opposed thereto, the error falls within an allowable range. In addition, what is necessary is just to satisfy | fill predetermined conditions, when A and B are equal.

  Therefore, a control width P corresponding to a distance of 1/2 of B is set on the floor block 101 having the beam specified by the beam position specification line 100 as a part of the boundary. The total length of the beam is A. The floor weight information 18 is acquired by 26 shown in FIG. Thereby, the floor weight 57 of the floor block 101 per unit area is calculated. When the unit floor weight is M, the product of A, P, and M is a shared load 58 for supporting the floor with the floor block 101 of the beam designated by the beam position designation line 100. The same calculation is performed for the floor block 102. Then, both shared loads are accumulated.

  On the other hand, in the example shown in FIG. 4B, the floor block 103 has the same shape as the floor block 101, but the floor block 104 has the beam designated by the beam position designation line 100 on the short side. . In such a case, the beam on the long side supports the total floor load of the floor block 104, and the beam specified by the beam position specification line 100 does not share the load. Therefore, when any beam is specified by the beam position specification line 100, all floors having the beam as a side are detected, the long side of each floor is searched, and the beam corresponds to the long side. It is determined that a predetermined condition is satisfied.

  Note that the wall position information 15 included in the floor plan data 30 used for floor detection as described above only needs to include information about the periphery of the beam to be subjected to strength calculation. The wall type information 17 is sufficient if it can be determined whether it is a bearing wall. The beam subjected to the strength calculation may be an existing beam, or may be a virtual beam that is planned to be newly constructed by extension and renovation. If an existing object is the target, it can be determined whether the tree species and size of the beam are appropriate. A rough floor plan of an existing building including an extension / renovation part should be created at the time of estimation.

  As described above, by collecting as accurate information as possible in the appearance inspection of the building and determining a certain control width calculation method in advance, the variation in the calculation results is minimized. For example, the load calculation means 46 calculates in advance the error that the accuracy of the information used to calculate the accumulated value 59 has on the accumulated value 59. A measurement error is allowed in a range where the dimension selection result of the standard beam based on the cumulative value 59 does not change. If a certain calculation method as described above is not defined, the difference in the dimensions of the beams required at the same place may reach two or more ranks due to differences in the person in charge of estimation design. For example, the vertical dimension of the beam may be 150 cm, 180 cm, or 210 cm depending on the plan. When strictly calculating based on the design drawing of the building, even if the 180 cm one is suitable, the designer may decide that the 150 cm one is necessary or 210 cm is necessary. On the other hand, if a certain uniform calculation method is determined as described above, the relationship between the accumulated value and the corresponding beam dimension is adjusted in the beam selection table 60, so that it is always set to the optimum value or to the safe side. A practical system can be constructed by selecting a beam having a dimension shifted by one rank.

  The information stored in the storage device includes a mixture of relatively accurate information measured on site and general information. If the information with relatively high accuracy is used as data for creating a specific extension / reconstruction design drawing, the work efficiency is good. On the other hand, there is information that allows a certain error in order to prioritize work efficiency and obtain data without breaking walls and floors. If you save these data as update target data that can be replaced with more accurate information so that it can be distinguished from other data, the strength of the beam can be calculated with very high accuracy after information replacement. . It is preferable that the information acquisition means manages the information stored in such a manner that the stored information is classified or identification information is given so that the distinction can be made.

Embodiments of a computer program for realizing the system of the present invention will be described below with reference to flowcharts.
FIG. 5 is a flowchart showing an operation procedure until the arithmetic processing unit 5 acquires the floor plan data 30. Steps S11 to S19 are processing procedures based on the functions of the designation means 40, the drawing control means 41, and the display control means 42. Steps S <b> 20 to S <b> 22 are processing procedures based on the function of the information acquisition unit 43.

  In step S11, the operation screen 12 is displayed first. In step S12, the grid 13 is displayed on the operation screen 12. The grid points 14 of the grid 13 are set so as to be snapped. In step S13, input floor selection data is acquired. That is, data such as whether floor plan data is created for the first floor or whether data is created for the second floor is acquired. The input of the line segment 21 is started after step S14. First, the designated lattice point 14 is detected. When two lattice points 14 are detected, line segment data 32 is acquired in step S15.

  In step S16, the line segment data 32 is stored in the storage device 3. In step S17, a wall line is drawn on the operation screen 12 based on the line segment data 32 thus stored. In step S18, the window 26 or the like is displayed to acquire the wall magnification. Wall magnification is used to determine the type of wall. Thus, the wall position information 15 and the wall type information 17 are acquired for one wall. In the next step S19, it is determined whether or not all the wall lines have been drawn. If not completed, the process returns to step S14 to accept the next wall line input. Step S14 or line step S19 is repeated in this way, and when all necessary wall lines have been input, the process proceeds to step S20.

  In step S20, floor position information 16 is acquired. That is, information is acquired as to whether a range surrounded by a wall line corresponds to a floor or a space. In step S21, it is determined whether or not the input of the floor position information 16 has been completed for all floors. If not completed, the process returns to the immediately preceding step S20, and another floor position information 16 is acquired. When the input of the floor position information is completed, the floor plan data 30 is stored in the storage device 3 in the last step S22. The above data is sufficient for the beam selection calculation processing in the present invention. Therefore, description of other information input processing is omitted. Actually, data necessary for extension and renovation of buildings is input from various angles, and estimation calculation processing is performed.

  FIG. 6 is a flowchart specifically showing a processing procedure until the arithmetic processing unit 5 calculates the accumulated value and outputs the beam tree type and dimensions. Step S31 is based on the function of the beam designating means 44. Step S32 is based on the function of the floor detection means 45. Steps S33 to S40 are based on the function of the load calculation means 46. Steps S 41 to S 43 are processing procedures based on the function of the beam selection means 47.

  First, in step S31, the designation of the beam position is detected. That is, in the floor plan data displayed on the operation screen 12, the beam position can be specified at an arbitrary place using the beam position specifying line 22 (FIG. 1). When a part of the building is demolished at this part in the case of extension and renovation and a room is newly added, the corresponding position is designated as the beam position. Alternatively, a portion that is considered to require reinforcement of the beam is arbitrarily designated, and this is designated as the beam position.

  In step S32, the detection process is performed using the floor having the designated beam position as one side as the target floor. This is based on the calculation of dividing the floor plan data into floor blocks surrounded by bearing walls and selecting the floor with the beam to be calculated as one side. Next, in step S33, the floor length is acquired. In step S34, it is determined whether the designated beam has a long side. If the beam is a long side, the shared load calculation from step S35 is performed. If the beam is a short side, the process jumps to step S39 to start calculation for another floor.

  In step S35, the control width P is calculated. The control width P is a width corresponding to one half of the short side of the length B when the beam to be calculated is the long side of the length A as described above. Next, a floor area is calculated in step S36. This is determined by the product of the beam length A and the control width P. In step S37, the unit floor weight M is calculated. Finally, the shared load is calculated from the acquired data. It is obtained by the product of P, A and M. In step S39, it is determined whether another floor needs to be calculated. If yes, the process returns to step S32 and the same calculation is repeated for another floor.

  In this way, the shared load is calculated for all the floors having the designated beam as the side, and these accumulated values are calculated in step S40. In the next step S41, the beam selection table 60 is referenced to select the beam tree type and dimensions corresponding to the accumulated value. When a beam is selected in step S42, the selection result is included in the window 26 and displayed on the operation screen 12 in step S43.

As described above, according to the system of the present invention, the following effects can be expected at the time of renovation design of a wooden house.
1. Renovation design is possible even if there is no blueprint for the target building.
2. Without destroying the building to be refurbished, it is possible to estimate and calculate within an error range that can be ignored by just checking the external structure.
3. The type of data to be input and the amount of data can be reduced and results can be obtained quickly.
4). If a portable computer, for example, a notebook type computer is used, the earthquake resistance of an existing building can be diagnosed on the spot at the time of a repair meeting with a customer.
5). The basis data used for the calculation is clearly distinguished between the accurate data that can be confirmed from the external structure and the estimated data for the rough calculation. When the structure is found, it is possible to review the design with higher accuracy by inputting additional correction information.

  In addition, the computer program installed in said arithmetic processing apparatus may be comprised combining each independent program module, and may be comprised by the program which integrated the whole. All or part of the processing controlled by the computer program may be configured by hardware having equivalent functions. Further, the above computer program may be used by being incorporated into an existing application program.
