Description

[Technical field]

[0001] The present invention relates to a wall connecting member placement determination support program and an information processing device that executes the program, and in particular to a wall connecting member placement determination support program that determines the placement of a wall connecting member based on the allowable strength of the wall connecting member, and an information processing device that executes the program. [Background technology]

[0002] Conventionally, in order to prevent the collapse of temporary scaffolding installed around a building under construction, wall connecting members are used to connect the temporary scaffolding to the building frame (walls, etc.). Patent Document 1 describes a wall connecting member that connects to an exterior wall panel through a horizontal joint formed between the exterior wall panels. The wall connecting member described in Patent Document 1 has a base end fixed to the support of the temporary scaffolding and a tip end fixed to the frame of the exterior wall panel. This makes it possible to keep a constant distance between the temporary scaffolding and the building, and to prevent the temporary scaffolding from collapsing and stabilize it.

[0003] Here, the Industrial Safety and Health Regulations stipulate that wall tie members must be placed at intervals of 5 meters or less in the vertical direction and 5.5 meters or less in the horizontal direction (Article 570 of the Industrial Safety and Health Regulations). Therefore, at construction sites, the above regulations are complied with by placing wall tie members based on two layers and three spans of temporary scaffolding. To explain in detail, temporary scaffolding for residential use has a height of 1900 mm per layer (one stage) and a span of 1800 mm. Therefore, by placing wall tie members every two layers and three spans of temporary scaffolding, the vertical interval is 3.8 meters and the horizontal interval is 5.4 meters, and the regulations set forth in the Industrial Safety and Health Regulations can be complied with.

[0004] Furthermore, when protective materials such as mesh sheets are provided on the scaffolding, the wall tie members can be arranged based on two layers and two spans of the scaffolding, taking into consideration the wind load applied to the scaffolding through the mesh sheets. This allows the wall tie members to be arranged at vertical intervals of 3.8 meters and horizontal intervals of 3.6 meters. This makes it possible to more reliably prevent the scaffolding from collapsing, even when the wind has a large effect. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2020-056162 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, the effects of wind vary greatly depending on the environment of the construction area and the condition of nearby structures (for example, whether there are high-rise buildings nearby). In addition, the wind load acting on the temporary scaffolding through protective materials such as mesh sheets also varies depending on the type of protective material. For this reason, uniformly arranging wall connecting members based on a two-layer, three-span or two-layer, two-span standard for temporary scaffolding may result in excessive arrangement of wall connecting members, and so it has been desired to optimally arrange them for each construction area and construction conditions.

[0007] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a wall connecting member placement determination support program that can assist in determining the optimal placement of wall connecting members for each construction area and construction conditions, thereby reducing construction costs and alleviating the construction burden, and an information processing device that executes the program. [Means for solving the problem]

[0008] The above-mentioned problem is solved by the wall connecting member placement decision support program of the present invention, comprising: a computer that supports the decision of placement of a wall connecting member that connects a building structure and a temporary scaffolding, comprising: placement condition acquisition means for acquiring placement conditions including building structure information including dimensions and placement of exterior wall panels that constitute the exterior wall of the building structure, wind speed information regarding wind speed in a construction area of ​​the building structure, and curing material information regarding curing materials to be stretched on the temporary scaffolding; placement candidate position identification means for identifying placement candidate positions at which the wall connecting member can be placed based on the dimensions and placement of the exterior wall panels included in the building structure information; This problem is solved by having the device function as: a maximum spacing calculation means which estimates the wind load acting on the temporary scaffolding based on the placement conditions, and calculates the maximum placement spacing of the wall connecting members based on the result of the estimation and the allowable strength of the wall connecting members; a placement determination means which determines the placement of the wall connecting members based on the placement candidate position identified by the placement candidate position identification means and the maximum placement spacing calculated by the maximum spacing calculation means; and a placement output means which outputs the placement of the wall connecting members determined by the placement determination means together with the structural information.

[0009] According to the above configuration, the wall connecting member placement decision support program includes a placement candidate position specifying means for specifying a placement candidate position where the wall connecting member can be placed based on the structural information of the building under construction, a maximum interval calculation means for estimating the wind load on the temporary scaffolding and calculating the maximum placement interval of the wall connecting member based on the wind load and the allowable strength of the wall connecting member, a placement determination means for determining the placement of the wall connecting member based on the placement candidate position and the maximum placement interval, and a placement output means for outputting the placement of the wall connecting member together with the structural information. Here, the structural information includes information on the dimensions and placement of the exterior wall panel to which the wall connecting member is attached. Therefore, the wall connecting member placement decision support program can support the determination of the optimal placement of the wall connecting member for each building, and can reduce construction costs and construction burdens compared to the case where the wall connecting member is placed more than necessary. In addition, the worker can easily grasp which of the multiple exterior wall panels the wall connecting member should be connected to.

[0010] In addition, the wind speed information includes statistical information on the wind speed defined for each region, and the curing material information includes a solidity ratio defined for each type of curing material, and the maximum spacing calculation means estimates the wind load acting on the temporary scaffolding based on the statistical information and the solidity ratio. According to the above configuration, the maximum interval calculation means estimates the wind load acting on the temporary scaffolding based on the statistical information of wind speeds that differ from region to region and the filling rate of the curing material that differs from construction site to construction site. Therefore, the wall-connecting member placement determination support program can flexibly determine the optimal placement of the wall-connecting members.

[0011] In addition, the placement condition acquisition means may include a region selection receiving means for receiving a selection of the construction region, and a protective material selection receiving means for receiving a selection of the type of protective material, and may acquire the wind speed information based on the construction region received by the region selection receiving means, and acquire the protective material information based on the type of protective material received by the protective material selection receiving means. According to the above configuration, the placement condition acquisition means has an area selection receiving means and a curing material selection receiving means, and acquires wind speed information and curing material information based on the selected construction area and type of curing material. Therefore, the user does not need to manually input wind speed information and curing material information, which improves convenience.

[0012] In addition, the maximum spacing calculation means may estimate wind load at the arrangement candidate position that is located on the uppermost floor among the plurality of arrangement candidate positions, and calculate the maximum placement spacing based on the result of the estimation and the allowable strength. According to the above configuration, the maximum interval calculation means estimates the wind load at the top floor position where the wind load is the largest among the multiple placement candidate positions, and calculates the maximum placement interval of the wall tie members based on the estimation result. Therefore, it is possible to improve the stability of the temporary scaffolding. In addition, it is possible to shorten the execution time of the wall tie member placement decision support program compared to the case where the wind load is calculated for all placement candidate positions.

[0013] The positioning determination means may further include a first positioning determination means for determining the position of the wall connecting member at a first position adjacent to one of the four corners of the main body among the plurality of candidate positioning positions, and a second positioning determination means for determining the position of the wall connecting member at a second position which is equal to or smaller than the maximum positioning interval and is furthest along the outer wall from the determined position at which the position of the wall connecting member has already been determined among the plurality of candidate positioning positions. According to the above configuration, the placement of the wall-connecting members can be determined by a simple method, and the worker can easily understand the placement of the wall-connecting members.

[0014] In addition, the structural information may include an exterior wall panel floor plan image depicting the exterior wall panel, and the layout output means may output the layout of the wall connecting members determined by the layout determination means by superimposing it on the exterior wall panel floor plan image. According to the above configuration, the optimal placement of the wall connecting members is output by superimposing it on the exterior wall panel floor plan image, so that it is easy to understand which of multiple exterior wall panels the wall connecting members should be attached to, thereby making it possible to reduce the construction burden.

[0015] In addition, the maximum spacing calculation means calculates the maximum placement spacing in the horizontal direction of the wall connecting members, and the placement determination means may have a first placement determination means for determining the horizontal placement of the wall connecting members based on the candidate placement positions and the maximum placement spacing in the horizontal direction, and a second placement determination means for estimating the wind load acting on the temporary scaffolding based on the horizontal placement determined by the first placement determination means, and for determining the vertical placement of the wall connecting members based on the result of the estimation and the allowable strength of the wall connecting members. According to the above configuration, it is possible to assist in determining the optimal horizontal and vertical placement of wall connecting members for each construction area and construction conditions, which makes it possible to reduce construction costs and construction burdens compared to the case where more wall connecting members are placed than necessary.

[0016] In addition, the second positioning determination means provisionally determines the vertical positioning of the wall connecting member, estimates the maximum value of the wind load acting on the temporary scaffolding based on the provisionally determined vertical positioning and the horizontal positioning of the wall connecting member determined by the first positioning determination means, and determines the vertical positioning of the wall connecting member based on the result of the estimation and the allowable strength of the wall connecting member. According to the above configuration, the position of the wall connecting members is provisionally determined, and the vertical position of the wall connecting members is determined based on the estimated maximum wind load and the allowable strength of the wall connecting members, thereby making it possible to reliably prevent the temporary scaffolding from collapsing.

[0017] In addition, the structural information includes an exterior wall panel floor plan image and an exterior wall panel elevation image on which the exterior wall panel is depicted, and the arrangement output means outputs the horizontal arrangement and the vertical arrangement of the wall connecting member determined by the arrangement determination means by superimposing them on at least one of the exterior wall panel floor plan image and the exterior wall panel elevation image. According to the above configuration, the optimal placement of the wall connecting members is output by superimposing it on at least one of the exterior wall panel floor plan image and the exterior wall panel elevation image, making it possible to easily grasp the positions at which the wall connecting members should be attached and reducing the burden of construction.

[0018] In addition, the information processing device may include a processor, and the processor may be made to execute a wall-connecting arrangement determination support program. According to the above configuration, the information processing device can assist in determining the optimal placement of wall connecting members for each building, making it possible to reduce construction costs and construction burdens compared to cases where more wall connecting members are placed than necessary. Effect of the Invention

[0019] According to the wall connecting member placement decision support program of the present invention and an information processing device that executes the program, it is possible to support the decision of the optimal placement of wall connecting members for each construction area and construction conditions, thereby making it possible to reduce construction costs and ease the construction burden.

[0021] An embodiment of the present invention (hereinafter, this embodiment) will be described below with reference to Figs. 1 to 9. In addition, hereinafter, a house (specifically, a detached house, or a collective housing such as an apartment or condominium) will be described as an example of a building. However, a house is only an example of a building, and the present invention can also be used in determining the placement of wall connecting members in the construction of other buildings, such as a commercial building, a building in a factory, a store, etc.

[0022] In the following description, the "vertical direction" refers to the direction corresponding to the height direction of a house, which is a building, and the "horizontal direction" refers to the direction corresponding to the row direction or beam direction of the house.

[0023] <About the exterior wall W, temporary scaffolding FT, and wall joint members WJ> First, the exterior wall W, the temporary scaffolding FT, and the wall connecting members WJ will be described with reference to Figs. As shown in Fig. 1, the exterior wall W of a house is composed of multiple exterior wall panels P arranged at equal intervals in the vertical and horizontal directions. Joints J are formed between the exterior wall panels P. More specifically, horizontal joints J1 extending horizontally and vertical joints J2 extending vertically are formed between the exterior wall panels P.

[0024] Fig. 2 is a perspective view of the exterior wall panel P with the upper exterior wall panel P removed. Fig. 3 is a plan view of the exterior wall panel P as seen from above. As shown in Figs. 2 and 3, the exterior wall panel P has a face material P1, a ventilation layer P2, and a heat insulating layer P3.

[0025] The facing material P1 is a plate material that faces the outdoors and is substantially rectangular in front view. Specifically, the facing material P1 is composed of a siding board. In the exterior wall panel P, the upper end of the facing material P1 is located slightly below the upper end of the insulating layer P3, and the lower end of the facing material P1 is located below the lower end of the insulating layer P3. Therefore, the upper end portion of the lower insulating layer P3 is located at the back side of the horizontal joint J1 formed between two exterior wall panels P adjacent to each other in the vertical direction.

[0026] The ventilation layer P2 is provided between the facing material P1 and the insulating layer P3 described below. More specifically, the ventilation layer P2 forms an internal space of the exterior wall panel P with a spacer P4 interposed between the facing material P1 and the insulating layer P3. The ventilation layer P2 keeps the exterior wall panel P dry and plays a role in preventing internal condensation due to high humidity of the exterior wall panel P.

[0027] The insulating layer P3 has a first insulating layer P31 made of a high-density glass wool board and a second insulating layer P32 made of high-performance glass wool. The insulating layer P3 may be surrounded by a frame attached to the periphery of the exterior wall panel P. The first insulating layer P31 and the second insulating layer P32 reduce the influence of outside air, realizing a house that can reduce heating and cooling costs.

[0028] A wall connecting jig M having an L-shaped bend is attached to both horizontal ends of the upper end portion of the exterior wall panel P. The wall connecting jig M is a metal plate material and is a connecting jig that connects the exterior wall panel P and the wall connecting member WJ. In other words, the wall connecting jig M is fixed to the upper end portion of the exterior wall panel P by the fastening bolt BT, and can be connected and fixed to the wall connecting member WJ via the connecting hole M1.

[0029] Returning to Fig. 1, the temporary scaffolding FT is erected at a position separated by a predetermined distance from the outer wall W of the building under construction to provide a foothold for workers performing construction work. The temporary scaffolding FT mainly comprises a scaffolding board FT1 that serves as a foothold for workers, a support F2 that supports the scaffolding board FT1, and a handrail (not shown). In Fig. 1, the temporary scaffolding FT is a wedge-tightened scaffolding, but is not limited to this. The temporary scaffolding FT may be a single-tube scaffolding or a frame scaffolding.

[0030] The wall connecting members WJ are used to firmly fix the temporary scaffolding FT by connecting the temporary scaffolding FT to the outer wall W at regular intervals. The wall connecting members WJ have a base end WJ1, a tip end WJ2, a connection member WJ3, and a rotation operation member WJ4. The base end WJ1 is made of a pipe crank and is detachably fixed to the single pipe of the support F2. The tip end WJ2 is a cylindrical member having a threaded groove and is inserted into the connecting hole M1 of the wall connecting jig M to connect to the exterior wall panel P.

[0031] The connection member WJ3 is a rotating screw having an elongated shape, and connects the base end WJ1 and the tip end WJ2. The connection member WJ3 is screwed into the rotation operation member WJ4. Therefore, by rotating the rotation operation member WJ4 relative to the connection member WJ3, the overall length of the wall connecting member WJ expands or contracts.

[0032] When attaching the wall connecting member WJ to the exterior wall panel P, first, the tip end WJ2 is inserted into the connecting hole M1 of the wall connecting jig M to connect it. Next, the base end WJ1 of the wall connecting member WJ is fixed to the support FT2 of the temporary scaffolding FT or to the handrail. Finally, the wall connecting member WJ is extended or retracted by operating the rotation operating member WJ4 to adjust the distance between the exterior wall W and the temporary scaffolding FT. This fixes the distance between the temporary scaffolding FT and the exterior wall W at an appropriate distance, making it possible to firmly fix the temporary scaffolding FT to the exterior wall W.

[0033] 3 is a plan view of a state in which a plurality of exterior wall panels P are arranged side by side. As described above, the wall connecting jigs M that connect the wall connecting members WJ to the exterior wall panel P are attached to both ends of the exterior wall panel P. In other words, both ends of the exterior wall panel P to which the wall connecting jigs M are attached (more specifically, the positions of the connecting holes M1 of the wall connecting jigs M) are candidate positions where the wall connecting members WJ can be arranged.

[0034] Here, regarding the arrangement positions of the wall-connecting members WJ, conventionally, the wall-connecting members WJ have been uniformly arranged at intervals called "two layers, three spans" or "two layers, two spans." This will be explained in detail below. The temporary scaffolding FT has dimensions of 1,900 mm in height and 1,800 mm in span (horizontal length). "Two layers, three spans" means that the wall connecting members WJ are arranged based on the temporary scaffolding FT in a state where two sets are arranged vertically and three sets are arranged horizontally. "Two layers, two spans" means that the wall connecting members WJ are arranged based on the temporary scaffolding FT in a state where two sets are arranged vertically and two sets are arranged horizontally.

[0035] Conventionally, by uniformly arranging the wall connecting members WJ at predetermined intervals in this way, there was a risk of excessive wall connecting members WJ being arranged. Therefore, it has been desired to flexibly determine the arrangement of the wall connecting members WJ for each building structure characteristic, construction area, or construction site, thereby suppressing construction costs and reducing the construction burden. The wall connecting member arrangement determination support terminal 10 described later is an information processing device capable of supporting the determination of the optimal arrangement of the wall connecting members WJ.

[0036] <Outline of the wall-connecting member placement decision support terminal 10> First, an overview of the wall-connecting member placement determination support terminal 10 will be described. The wall-connecting member placement determination support terminal 10 is used to support optimal placement determination of the wall-connecting members WJ. In the following description, optimization of the wall-connecting members WJ means minimizing the number of wall-connecting members WJ placed while preventing the temporary scaffolding FT from collapsing by the wall-connecting members WJ.

[0037] In order to prevent the collapse of the temporary scaffolding FT using the wall connecting members WJ, the condition shown by the following equation (1) must be satisfied. JD>WP (1) Here, JD is the allowable strength that the wall-connecting members WJ can use to prevent the scaffolding FT from collapsing, and WP is the wind load acting on the scaffolding FT, which is proportional to the area of ​​the exterior wall panel P determined by the spacing of the wall-connecting members WJ.

[0038] Figure 4 shows the relationship between the spacing of the wall tie members WJ and the wind load. As shown in Figure 4, when the wall tie members WJ are placed every two exterior wall panels P in the vertical direction and every two exterior wall panels P in the horizontal direction, the wall tie members WJ will receive a wind load WP corresponding to the area of ​​the four exterior wall panels P. On the other hand, if a wall connecting member WJ is placed for every two exterior wall panels P in the vertical direction and every four exterior wall panels P in the horizontal direction, the wall connecting member WJ will receive a wind load WP corresponding to the area of ​​eight exterior wall panels P. Therefore, the wall connecting member WJ needs to have twice the allowable wind load resistance compared to the case where there are four exterior wall panels P.

[0039] Furthermore, when a wall connecting member WJ is arranged for every two exterior wall panels P in the vertical direction and every six exterior wall panels P in the horizontal direction, the wall connecting member WJ will bear the wind load WP corresponding to the area of ​​the 12 exterior wall panels P. Therefore, the wall connecting member WJ needs to have three times the allowable wind load resistance compared to when there are four exterior wall panels P.

[0040] In Japan, wall tie members WJ must have a certain allowable strength, specifically, an allowable strength of 450 kgf or more. Therefore, the placement interval of wall tie members WJ must be determined so that the wind load WP is less than 450 kgf, using formula (1). The method for calculating wind load WP will be described later, but it is calculated based on the wind pressure generated by the wind speed, the wind force coefficient which is a coefficient for the wind pressure, and the exterior wall area on which the wall tie members WJ bear the wind load.

[0041] As described below, the wall connecting member placement determination support terminal 10 is an information processing device capable of presenting to the user the placement of wall connecting members WJ such that the wind load WP acting on the temporary scaffolding FT does not exceed the allowable strength of the wall connecting members WJ and such that the number of wall connecting members WJ to be placed is minimized.

[0042] <Configuration of the wall-connecting member placement decision support terminal 10> The wall connector member placement determination support terminal 10 is a desktop PC that presents the optimal placement of the wall connector members WJ to the user, but is not limited to this. The wall connector member placement determination support terminal 10 may be a notebook PC or a tablet terminal.

[0043] Fig. 5 is a diagram showing the configuration of the wall-connecting member placement determination support terminal 10. As shown in Fig. 5, the wall-connecting member placement determination support terminal 10 mainly includes an input device 11, a display device 12, a communication I / F 13, a storage device 14, and a control device 15.

[0044] The input device 11 is an input device including a keyboard and a mouse, and receives operational input from a user who is considering the optimal arrangement of the wall connecting members WJ. The display device 12 is a display device made up of an LCD (liquid crystal display). The display device 12 displays an exterior wall panel floor plan image (see FIG. 9) in which the arrangement of the wall connecting members WJ is superimposed on the exterior wall panel floor plan.

[0045] The communication I / F 13 is a communication device that performs data communication with an external communication device. Specifically, the communication I / F 13 is a communication device that can communicate via a wired LAN or a wireless LAN. The wall connecting member placement determination support terminal 10 may be able to access a publicly available electric communication line (e.g., an Internet line) via the communication I / F 13.

[0046] The storage device 14 is a non-volatile auxiliary storage device consisting of a hard disk drive (HDD) or a solid state drive (SSD), etc. The storage device 14 has a structure information storage unit 141, a wind speed information storage unit 142, a curing material information storage unit 143, and a program storage unit 144.

[0047] The structural body information storage unit 141 stores structural body information including information on the dimensions and arrangement of the pillars, beams, and exterior wall panels P of the house. The structural body information may also include information on the arrangement of wall connecting jigs M attached to the exterior wall panels P. A candidate arrangement position specification means 152, which will be described later, acquires the structural body information and specifies candidate arrangement positions where the wall connecting members WJ can be arranged. A maximum interval calculation means 153, which will be described later, acquires the structural body information and acquires the height above ground when calculating the wind load. The structural body information may also include an exterior wall panel floor plan image.

[0048] The wind speed information storage unit 142 stores wind speed information including statistical information on wind speeds determined for each region. Specifically, the wind speed information includes a statistically obtained standard wind speed, a typhoon premium coefficient, an instantaneous wind speed distribution coefficient, and a premium coefficient for nearby high-rise buildings. The wind speed information storage unit 142 stores the standard wind speed, typhoon premium coefficient, instantaneous wind speed distribution coefficient, and premium coefficient for nearby high-rise buildings determined by the Temporary Construction Industry Association, but is not limited to these. It is sufficient to be able to calculate the wind speed pressure required to calculate the wind load with sufficient accuracy, and the wind speed information storage unit 142 stores parameters required for calculating the wind speed pressure. The method of calculating the wind speed pressure will be described later.

[0049] The curing material information storage unit 143 stores curing material information including the solidity of the curing material for each type of curing material. The solidity of the curing material means the ratio of the actual area to the size of the curing material (the value obtained by multiplying the vertical dimension by the horizontal dimension). The wind force coefficient used in the calculation of the wind load WP described above is calculated based on the solidity of the curing material stretched on the temporary scaffolding FT, the aspect ratio of the curing material, and the stretched position (height) of the curing material. The curing material information storage unit 143 stores solidity rates determined by the General Incorporated Association Temporary Construction Industry Association, but is not limited to these. The curing material information storage unit 143 stores required parameters for calculating the wind force coefficient. The method of calculating the wind force coefficient will be described later.

[0050] The program storage unit 144 stores a program executed by the control device 15, which will be described later. Specifically, the program storage unit 144 stores a program for executing a wall connector member placement determination support process and a wall connector member layout process, which will be described later with reference to Figs. 7 and 9.

[0051] The control device 15, which corresponds to a computer, has as its main components a CPU, which corresponds to a processor, a volatile memory, and a non-volatile memory, and is responsible for controlling the wall connecting member placement determination support terminal 10. The CPU performs various information processing and control by executing programs stored in the non-volatile memory and the program storage unit 144. As a result, the control device 15 functions as a placement condition acquisition means 151, a placement candidate position identification means 152, a maximum interval calculation means 153, a placement determination means 154, and an exterior wall panel floor plan output means 155.

[0052] The placement condition acquisition means 151 acquires various placement conditions (parameters) necessary for determining the optimal placement of the wall tie members WJ. Specifically, the placement condition acquisition means 151 reads and acquires structural body information, wind speed information, and curing material information from the structural body information storage unit 141, the wind speed information storage unit 142, and the curing material information storage unit 143, respectively. However, the method of acquiring the placement conditions is not limited to this. The placement condition acquisition means 151 may acquire the placement conditions input by a user who operates the wall tie member placement determination support terminal 10 via the input device 11. Also, the placement condition acquisition means 151 may acquire the placement conditions from an external information processing device via the communication I / F 13.

[0053] The arrangement condition acquisition means 151 may have an area selection receiving means for receiving a selection of a construction area. In other words, it is preferable that the arrangement condition acquisition means 151 can receive a selection of a construction area by a user and read out wind speed information corresponding to the construction area from the wind speed information storage unit 142. This can reduce the user's effort in manually inputting wind speed information. The arrangement condition acquisition means 151 may also have a curing material selection receiving means for receiving a selection of the type of curing material. In other words, it is preferable that the arrangement condition acquisition means 151 can receive the selection of the type of curing material by the user and read out the curing material information corresponding to the curing material from the curing material information storage unit 143. This can reduce the effort required for the user to manually input the curing material information.

[0054] The arrangement candidate position specifying means 152 specifies an arrangement candidate position where the wall connecting member WJ can be arranged, based on the dimensions and arrangement of the exterior wall panel P included in the structural body information acquired by the arrangement condition acquisition means 151. In detail, the arrangement candidate position specifying means 152 specifies the arrangement candidate position of the wall connecting member WJ to the position of the connection hole M1 of the wall connecting jig M attached to both ends of the multiple exterior wall panels P. However, without being limited thereto, the arrangement candidate position specifying means 152 may specify the arrangement candidate position of the wall connecting member WJ to a position at a predetermined distance (for example, 5 cm) from both ends of the multiple exterior wall panels P in the horizontal direction.

[0055] The maximum interval calculation means 153 estimates the wind load acting on the temporary scaffolding FT based on the structural body information, wind speed information, and curing material information acquired by the arrangement condition acquisition means 151, and calculates the maximum arrangement interval of the wall-connecting members WJ based on the estimation result and the allowable strength of the wall-connecting members WJ. The method of calculating the maximum arrangement interval will be described in detail below.

[0056] First, the wind load WP will be described. The wind load WP can be calculated by the following formula (2). WP = qz × C × A (2) Here, qz is the wind pressure caused by the wind speed at a height of z meters above ground. C is the wind force coefficient, which is a coefficient for the wind pressure, and A is the exterior wall area on which the wall joint WJ bears the wind load.

[0057] The wind speed pressure qz can be calculated based on the design wind speed expected in the construction area using the following equations (3) and (4). qz=5 / 8×Vz^2 (3) Vz=Vo×Ke×S×Eb (4) where Vz is the design wind speed in the construction area, Vo, Ke, S, and Eb are the standard wind speed in the construction area, the typhoon surcharge coefficient, the instantaneous wind speed distribution coefficient at height z above ground level, and the surcharge coefficient due to nearby high-rise buildings, respectively.

[0058] The standard wind speed Vo, typhoon premium coefficient Ke, instantaneous wind speed distribution coefficient S, and nearby high-rise building premium coefficient Eb in the construction area are statistical values ​​determined for each area by the Temporary Construction Industry Association, but are not limited to these. The standard wind speed Vo, typhoon premium coefficient Ke, instantaneous wind speed distribution coefficient S, and nearby high-rise building premium coefficient Eb in the construction area may be values ​​modified by the user.

[0059] The wind force coefficient C can be calculated using the following formula (5) based on the attributes of the protective material installed on the temporary scaffolding FT. C=(0.11+0.09×(1-φ)+0.945×Co+R)×F (5) Here, φ, Co, R, and F are the solidity ratio of the curing material, the basic wind force coefficient of the vertical curing material, the shape coefficient based on the aspect ratio of the vertical curing material, and the correction coefficient based on the scaffolding installation position, respectively.

[0060] Figure 6 shows the relationship between the type of curing material installed on the temporary scaffolding FT and the solidity ratio φ. As shown in Figure 6, the main curing materials known are vertical nets, mesh sheets, fireproof sheets, and soundproof panels.

[0061] The vertical net is a lightweight protective material that is stretched over the temporary scaffolding FT and used until the mesh net is installed. Mesh sheets are sheets made of flame-retardant or flame-resistant synthetic fiber mesh fabric, and are classified into mesh sheets Class 1 and mesh sheets Class 2. Mesh sheets Class 1 are used to prevent injury from flying or falling objects, and have higher tensile strength than mesh sheets Class 2. Mesh sheets Class 2 are protective sheets that are lighter than mesh sheets Class 1, but have lower tensile strength. Fire-retardant sheets are protective sheets that have higher fire-retardant performance than mesh sheets, and are classified into Class 1 fire-retardant sheets, which have high tensile strength, and Class 2 fire-retardant sheets, which are lighter than Class 1 fire-retardant sheets. Soundproofing panels are protective panels that can reduce noise during work.

[0062] Figure 6 shows the density ratio for each type of curing material, as determined by the Temporary Construction Industry Association. The density ratio can be considered an index of susceptibility to wind, with curing materials with a low density ratio being less susceptible to wind and not generating a large wind load when attached to temporary scaffolding FT. On the other hand, curing materials with a high density ratio are more susceptible to wind and generate a large wind load when attached to temporary scaffolding FT.

[0063] The basic wind force coefficient Co of vertical curing material is a coefficient obtained by inputting the solidity factor φ into a specified calculation formula. The shape coefficient R based on the aspect ratio of the vertical curing material is a coefficient obtained from the ratio of the vertical dimension to the horizontal dimension of the curing material. The installation position correction coefficient F is a coefficient determined based on the installation position of the temporary scaffolding FT (upper floor or other). The solidity ratio φ, basic wind force coefficient Co, shape coefficient R, and installation position correction coefficient F are obtained from the curing material information storage unit 143 by the user operating the wall connecting member placement decision support terminal 10 selecting from a selection of pre-set curing materials.

[0064] The exterior wall area A over which the wall connecting members WJ bear the wind load is obtained by multiplying the vertical spacing of the wall connecting members WJ by their horizontal spacing. In this embodiment, the vertical spacing is the dimension when two sets of exterior wall panels P are arranged vertically side by side. As an example, the vertical spacing is 3.64 meters. In this case, if the horizontal spacing is W, the exterior wall area A over which the wall connecting members WJ bear the wind load can be calculated by the following formula (6). A=3.64×W (6)

[0065] By substituting equations (2) and (6) into equation (1) and transforming it, the maximum horizontal placement interval Wmax of the wall-connecting members WJ can be calculated using the following equation (7). Wmax <JD / (3.64×qz×C) (7) As described above, the allowable strength JD of the wall-connecting member WJ is 450 kgf, and the wind speed pressure qz and wind force coefficient C can be calculated using equations (3), (4), and (5), respectively.

[0066] Generally, the wind speed increases as the height above ground increases, and the wind load increases accordingly. Therefore, the maximum interval calculation means 153 calculates the maximum arrangement interval by substituting the wind speed information at the height of the arrangement candidate position located at the top among the multiple arrangement candidate positions into formula (7).

[0067] The placement determination means 154 determines the placement of the wall-connecting member WJ based on the placement candidate position of the wall-connecting member WJ specified by the placement candidate position specification means 152 and the maximum placement interval of the wall-connecting member WJ calculated by the maximum interval calculation means 153. More specifically, the placement determination means 154 determines the wall-connecting member WJ to be placed at a position that is the furthest away from the placement determined position where the placement of the wall-connecting member WJ has already been determined among the multiple placement candidate positions and is equal to or less than the maximum placement interval. This makes it possible to prevent the temporary scaffolding FT from collapsing while suppressing excessive placement of the wall-connecting member WJ, thereby reducing the construction cost and the construction burden on workers. The placement determination method will be described in detail later.

[0068] The exterior wall panel floor plan output means 155 outputs the arrangement of the wall connector members WJ together with the exterior wall panel floor plan image. More specifically, the exterior wall panel floor plan output means 155 outputs the arrangement of the wall connector members WJ by superimposing it on the exterior wall panel floor plan image. This makes it easy to know which of the multiple exterior wall panels P the wall connector members WJ should be attached to, making it possible to reduce the construction burden at the construction site. The exterior wall panel floor plan output means 155 corresponds to an arrangement output means.

[0069] <Flow of wall connection component placement decision support process> Next, the flow of the wall-connecting member placement decision support process will be described. 7 shows a flow of a wall-connecting member placement decision support process. The wall-connecting member placement decision support process is performed by the CPU of the control device 15 executing a wall-connecting member placement decision support program stored in the program storage unit 144.

[0070] First, the control device 15 acquires the placement conditions of the wall connecting members WJ (step S10). In detail, the control device 15 accepts the selection of the construction target and the construction area, reads out the structural information of the selected construction target from the structural information storage unit 141, and reads out the wind speed information of the construction area from the wind speed information storage unit 142. The control device 15 also accepts the selection of the type of curing material to be stretched on the temporary scaffolding FT, and reads out the curing material information (solidity rate) of the selected curing material from the curing material information storage unit 143. However, without being limited thereto, the control device 15 may accept the input of structural information, wind speed information, and curing material information via the input device 11.

[0071] Next, the control device 15 specifies candidate positions for arranging the wall-connecting members WJ based on the structural body information (step S11). In detail, the control device 15 specifies candidate positions for arranging the wall-connecting members WJ at both ends of each of the multiple exterior wall panels P based on the dimensions and arrangement of the exterior wall panels P included in the structural body information. When the arrangement of the wall-connecting jigs M can be specified, the positions at which the wall-connecting jigs M are placed are specified as candidate positions for arranging the wall-connecting members WJ.

[0072] Next, the control device 15 calculates the maximum arrangement interval Wmax of the wall-connecting members WJ (step S12). In detail, the control device 15 calculates the maximum arrangement interval Wmax of the wall-connecting members WJ by substituting the structural body information, the wind speed information, and the curing material information into the formula (7).

[0073] Next, the control device 15 executes a wall-connecting member layout process (step S13). Fig. 8 shows the flow of the wall-connecting member layout process. Fig. 9 shows an exterior wall panel floor plan image showing the layout of the exterior wall panel P and the wall-connecting member WJ. The flow of the wall-connecting member layout process will be described with reference to Figures 8 and 9. First, the control device 15 determines the arrangement candidate positions a1, b1, c1, and d1 adjacent to the four corners of the building body BD as the arrangement positions of the wall-connecting members WJ (step S21, first arrangement determination means). In Figure 9, the building body BD has a rectangular shape in a plan view, and the arrangement candidate positions a1, b1, c1, and d1 adjacent to the protruding corners in the four directions are determined as the arrangement positions of the wall-connecting members WJ, but this is not limited to this. If the building body BD has an inside corner, the arrangement candidate positions adjacent to the inside corner may be determined as the arrangement positions of the wall-connecting members WJ. The arrangement candidate positions a1, b1, c1, and d1 adjacent to the corners correspond to the first arrangement positions.

[0074] Next, the control device 15 determines the placement candidate position a2 that is the furthest away from the placement determination position a1 where the wall connecting member WJ has already been placed in the direction of the arrow D1 along the exterior wall W, and is equal to or less than the maximum placement interval, as the placement position of the wall connecting member WJ (step S22, second placement determination means).

[0075] Next, the control device 15 determines whether or not a corner exists in the direction of the arrow D1 along the exterior wall W at a distance equal to or less than the maximum arrangement distance from the arrangement determination position a2 (step S23). If it is determined that a corner does not exist (step S23: No), the control device 15 returns to step S22 and again arranges the wall connecting member WJ.

[0076] If it is determined that a corner exists (step S23: Yes), the control device 15 changes the arrangement surface of the wall-connecting member WJ (step S24). In detail, thereafter, the control device 15 arranges the wall-connecting member WJ on the arrangement surface extending from the corner arrangement determination position b1 along the exterior wall W in the direction of the arrow D2.

[0077] Next, the control device 15 judges whether or not the wall-connecting members WJ have been arranged on all of the arrangement surfaces (step S25). If it is judged that the wall-connecting members WJ have not been arranged on all of the arrangement surfaces (step S25: No), the control device 15 determines the arrangement candidate position b2, which is the maximum arrangement interval or less and is the furthest away from the arrangement decision position b1 in the direction of the arrow D2, as the arrangement position (step S22).

[0078] Next, the control device 15 determines whether or not a corner exists in the direction of the arrow D2 along the exterior wall W at a distance equal to or less than the maximum arrangement interval from the arrangement determination position b2 (step S23). If it is determined that a corner does not exist (step S23: No), the control device 15 returns to step S22 and again arranges the wall connecting member WJ.

[0079] If it is determined that a corner exists (step S23: Yes), the control device 15 changes the arrangement surface of the wall-connecting member WJ (step S24). In detail, thereafter, the control device 15 arranges the wall-connecting member WJ on the arrangement surface extending from the corner arrangement determination position c1 along the exterior wall W in the direction of the arrow D3.

[0080] Next, the control device 15 judges whether the wall-connecting members WJ have been arranged on all of the arrangement surfaces (step S25). If it is judged that the wall-connecting members WJ have not been arranged on all of the arrangement surfaces (step S25: No), the control device 15 determines the arrangement candidate position c2, which is the maximum arrangement interval or less and is the furthest away from the arrangement decision position c1 in the direction of the arrow D3, as the arrangement position (step S22).

[0081] Next, the control device 15 determines whether or not a corner exists in the direction of the arrow D3 along the exterior wall W at a distance equal to or less than the maximum arrangement interval from the arrangement determination position c2 (step S23). If it is determined that a corner does not exist (step S23: No), the control device 15 returns to step S22 and again arranges the wall connecting member WJ.

[0082] If it is determined that a corner exists (step S23: Yes), the control device 15 changes the arrangement surface of the wall-connecting member WJ (step S24). In detail, thereafter, the control device 15 arranges the wall-connecting member WJ on the arrangement surface extending from the corner arrangement determination position d1 along the exterior wall W in the direction of the arrow D4.

[0083] Next, the control device 15 judges whether the wall-connecting members WJ have been placed on all placement surfaces (step S25). If it is judged that the wall-connecting members WJ have not been placed on all placement surfaces (step S25: No), the control device 15 determines the placement candidate position d2 that is the maximum placement interval or less and is the furthest away from the placement decision position d1 in the direction of the arrow D4 as the placement position (step S22). The positions a2, b2, c2, and d2 correspond to the second placement position.

[0084] Next, the control device 15 determines whether or not a corner exists in the direction of the arrow D4 along the exterior wall W at a distance equal to or less than the maximum arrangement interval from the arrangement determination position d2 (step S23). If it is determined that a corner does not exist (step S23: No), the control device 15 returns to step S22 and again arranges the wall connecting member WJ.

[0085] If it is determined that a corner exists (step S23: Yes), the control device 15 changes the placement surface of the wall-connecting member WJ (step S24). Next, the control device 15 determines whether the wall-connecting member WJ has been placed on all placement surfaces (step S25). The control device 15 has placed the wall-connecting member WJ on the placement surfaces extending from the placement determination positions a1, b1, c1, and d1d1 in the directions of the arrows D1, D2, D3, and D4, respectively. Therefore, the control device 15 determines that the wall-connecting member WJ has been placed on all placement surfaces (step S25: Yes), and ends the wall-connecting member layout process.

[0086] Returning to FIG. 7, the control device 15 outputs the arrangement of the wall connection members WJ together with the exterior wall panel floor plan (step S14). In detail, the control device 15 generates an image in which the arrangement of the wall connection members WJ is superimposed on the exterior wall panel floor plan image, and outputs the image to the display device 12 of the wall connection member arrangement determination support terminal 10. This makes it possible to easily grasp which of the multiple exterior wall panels P the wall connection members WJ should be attached to, thereby reducing the construction burden. In addition, the control device 15 may transmit and output the image in which the arrangement of the wall connection members WJ is superimposed on the exterior wall panel floor plan image to an external information processing device via the communication I / F 13. This makes it possible for a worker working on site to easily grasp which of the multiple exterior wall panels P the wall connection members WJ should be attached to, thereby reducing the construction burden.

[0087] The above describes the wall connector member placement decision support program and the wall connector member placement decision support terminal 10 according to one embodiment of the present invention. However, the above-described embodiment is merely an example to facilitate understanding of the present invention and does not limit the present invention. In the above embodiment, the wall-connecting member placement determination support program has been described as outputting the optimal placement of the wall-connecting members WJ together with the exterior wall panel floor plan image, but it may also be configured to accept changes to the placement of the output wall-connecting members WJ. This makes it possible to reflect the intention of the user considering the placement of the wall-connecting members WJ.

[0088] <Modification> In the above embodiment, the wall connecting jig M has an L-shaped bent shape and is attached to the heat insulating layer P3, but the present invention is not limited to this. FIG. 10 shows a wall connecting jig MA according to a modified example. As shown in FIG. 10, the wall connecting jig MA has an oval shape in a front view, and a connecting hole M1 for connecting to the wall connecting member WJ is formed at the center in the vertical direction. By using the wall connecting jig MA according to the modified example, the worker can easily grasp the installation position of the wall connecting member WJ. In addition, since the wall connecting jig MA according to the modified example is covered with a cover member (not shown) after the building is completed, it is possible to prevent the aesthetic appearance of the exterior wall W of the building from being damaged by the wall connecting jig MA. Even when the wall connecting jig MA according to the modified example is used, the present invention can achieve the same effects as the above-mentioned embodiment.

[0089] In the above embodiment, the wall joining jig M is described as being attached to the upper end portion of the exterior wall panel P. In contrast, the wall joining jig MA according to the modified example can be attached to any height position except the upper end portion of the exterior wall panel P. FIG. 11 is a diagram for explaining the arrangement candidate position PC in the above-mentioned embodiment and the arrangement candidate position PCA according to the modified example. As shown in FIG. 11, the wall joint jig M according to the above-mentioned embodiment can be attached to the horizontal joint J1 between the upper and lower exterior wall panels P. Therefore, the arrangement candidate position PC is located at the horizontal joint J1. On the other hand, the wall joint jig MA according to the modified example can be attached at any height position where the base material is disposed on the back of the face material P1. Therefore, the arrangement candidate position PCA according to the modified example is located at any height at both ends of the exterior wall panel P. In the following, a wall connector member placement determination support terminal 10A that supports the determination of the optimal placement of the wall connector members WJ in the horizontal and vertical directions will be described. In the following description, the same components as those in the above-mentioned embodiment will be denoted by the same reference numerals and their description will be omitted to clarify the differences in the components.

[0090] Fig. 12 is a diagram showing the configuration of the wall-connecting member placement determination support terminal 10A. As shown in Fig. 12, the wall-connecting member placement determination support terminal 10A mainly includes an input device 11, a display device 12, a communication I / F 13, a storage device 14, and a control device 15A.

[0091] The control device 15A, which corresponds to a computer, has as its main components a CPU, which corresponds to a processor, a volatile memory, and a non-volatile memory, and controls the wall connecting member placement determination support terminal 10A. The CPU performs various information processing and control by executing programs stored in the non-volatile memory and the program storage unit 144. As a result, the control device 15 functions as a placement condition acquisition means 151, a placement candidate position identification means 152, a maximum interval calculation means 153, a placement determination means 154, a vertical direction placement determination means 154A, an exterior wall panel floor plan output means 155, and an exterior wall panel elevation plan output means 155A.

[0092] The arrangement condition acquisition means 151, like the above-described embodiment, reads and acquires structural body information, wind speed information, and curing material information from the structural body information storage unit 141, wind speed information storage unit 142, and curing material information storage unit 143, respectively. As in the above-described embodiment, the placement candidate position identification means 152 identifies a horizontal placement candidate position where the wall connecting member WJ can be placed based on the dimensions and placement of the exterior wall panel P contained in the structural information acquired by the placement condition acquisition means 151.

[0093] As in the above-described embodiment, the maximum spacing calculation means 153 estimates wind load based on the structural information, wind speed information, and curing material information acquired by the placement condition acquisition means 151, and calculates the maximum horizontal placement spacing of the wall connecting members WJ from the estimation result and the allowable strength of the wall connecting members WJ. As in the above-described embodiment, the placement determination means 154 determines the horizontal placement of the wall-connecting members WJ based on the placement candidate positions identified by the placement candidate position identification means 152 and the horizontal maximum placement interval calculated by the maximum interval calculation means 153. The placement determination means 154 corresponds to a first placement determination means.

[0094] When the horizontal arrangement of the wall-connecting members WJ is determined by the arrangement determining means 154, the vertical arrangement determining means 154A estimates the wind load acting on the temporary scaffolding FT, and determines the vertical arrangement of the wall-connecting members WJ based on the estimation result and the allowable strength of the wall-connecting members WJ. In more detail, first, the vertical arrangement determining means 154A provisionally determines the vertical arrangement of the wall-connecting members WJ to 5-meter intervals as stipulated by the Industrial Safety and Health Regulations. Next, the vertical arrangement determining means 154A estimates the maximum value of the wind load based on the provisionally determined vertical arrangement and horizontal arrangement, compares the estimation result with the allowable strength of the wall-connecting members WJ, and determines the vertical arrangement by adjusting the vertical arrangement based on the comparison result. This makes it possible to reliably prevent the temporary scaffolding FT from collapsing while suppressing excessive vertical arrangement of the wall-connecting members WJ, thereby making it possible to reduce construction costs and reduce the construction burden on workers. The method for determining the vertical arrangement will be described later in detail.

[0095] The exterior wall panel floor plan output means 155 outputs the arrangement of the wall connecting members WJ together with the exterior wall panel floor plan image, similar to the embodiment described above. The exterior wall panel elevation output means 155A outputs the horizontal and vertical arrangement of the wall connecting members WJ together with the exterior wall panel elevation image. More specifically, the exterior wall panel elevation output means 155A outputs the arrangement of the wall connecting members WJ superimposed on the exterior wall panel elevation image. This makes it easy to know which of the multiple exterior wall panels P the wall connecting members WJ should be attached to, and reduces the construction burden at the construction site.

[0096] <Flow of wall connection component placement decision support process> Next, the flow of the wall-connecting member placement determination process will be described. 13 shows a flow of a wall-connecting member placement determination support process. The wall-connecting member placement determination support process is performed by the CPU of the control device 15A executing a wall-connecting member placement determination support program stored in the program storage unit 144. Steps S10 to S13 and step S14 are the same processes as those in the above-described embodiment.

[0097] First, the control device 15A acquires the arrangement conditions of the wall connecting members WJ (step S10). In detail, the control device 15A reads and acquires the structural information of the construction target, the wind speed information of the construction area, and the curing material information from the structural information storage unit 141, the wind speed information storage unit 142, and the curing material information storage unit 143, respectively.

[0098] Next, the control device 15A specifies candidate positions for arranging the wall-connecting members WJ based on the structural body information (step S11). In detail, the control device 15 specifies candidate positions PCA for arranging the wall-connecting members WJ at both ends of the exterior wall panel P excluding the horizontal joints J1 based on the dimensions and arrangement of the exterior wall panel P included in the structural body information.

[0099] Next, the control device 15A calculates the maximum arrangement interval Wmax of the wall-connecting members WJ in the horizontal direction (step S12). In detail, the control device 15A calculates the maximum arrangement interval Wmax of the wall-connecting members WJ by substituting the structural body information, the wind speed information, and the curing material information into the formula (7).

[0100] Next, the control device 15 executes a horizontal layout process (step S13). The horizontal layout process executes the same process as the wall connector member layout process described with reference to Fig. 8, and determines the horizontal arrangement of the wall connector members WJ. The wall connector member layout process has been described above, so a detailed description thereof will be omitted here.

[0101] Next, the control device 15A executes a vertical layout process (step S13A). Details of the vertical layout process will be described below with reference to FIGS. Fig. 14 shows the flow of the vertical layout process. Fig. 15 shows the initial arrangement (provisionally determined arrangement) of the wall joint members WJ, and Fig. 16 is an elevation view showing the finally determined arrangement of the wall joint members WJ. In Figs. 15 and 16, three exterior wall panels P are arranged vertically and four horizontally, but the number and arrangement of the exterior wall panels P are not limited to the number and arrangement shown in Figs. 5 and 6.

[0102] First, the control device 15A provisionally determines the vertical placement of the wall-connecting members WJ (step S21A). In detail, the control device 15A provisionally determines the vertical intervals of the wall-connecting members WJ to be 5 meters apart as specified by the Industrial Safety and Health Regulations. As a result, a height H1 of 5 meters from the ground and a height H2 of 10 meters from the ground are provisionally determined as the placements of the wall-connecting members WJ for the first and second stages, respectively. More specifically, three first stage provisional placement positions PT1 are provisionally determined at a height of 5 meters from the ground, and three second stage provisional placement positions PT2 are provisionally determined at a height of 10 meters from the ground.

[0103] Next, the control device 15A calculates the maximum bearing area of ​​the wall connection members WJ (step 22A). In detail, the control device 15A calculates the area that each of the wall connection members WJ shares and bears the wind load when a wind load is applied to the exterior wall W, that is, the maximum value of the bearing area. Here, the bearing area means the area of ​​the area having the midpoint of the wall connection members WJ adjacent to each other as a boundary line. To explain with a specific example, as shown in FIG. 15, the three wall connection members WJ arranged at the first stage temporary fixing position PT1 bear the wind load of the areas A11, A12, and A13, respectively. The area A12 has an area larger than the areas A11 and A13. Moreover, the three wall connection members WJ arranged at the second stage temporary fixing position PT2 bear the wind load of the areas A21, A22, and A23, respectively. The areas A21, A22, and A23 have areas smaller than the area A12. Therefore, the control device 15A calculates the area of ​​the region A12 as the maximum burden area by the following formula (8). A = Dh × Dw (8) Here, Dh and Dw are the height and width, respectively, of the area A12 as shown in Fig. 15. The height Dh is 7.5 meters, and the width Dw can be determined based on the horizontal arrangement of the wall tie members WJ determined in step S13.

[0104] Next, the control device 15A calculates the wind load WP at the maximum bearing area calculated in step S22A as the maximum wind load (step S23A). In detail, the control device 15A calculates the wind speed pressure qz and the wind force coefficient C using equations (3) to (5), and calculates the wind load WP by substituting them into equation (2) together with the bearing area calculated using equation (8).

[0105] Next, the control device 15A determines whether the allowable strength of the wall-connecting member WJ is greater than the maximum wind load (step S24A). In detail, the control device 15A determines whether the allowable strength of the wall-connecting member WJ is greater than the maximum wind load by comparing the allowable strength (450 kgf) of the wall-connecting member WJ defined in Japan with the maximum wind load calculated in step S23A.

[0106] If it is not determined that the allowable strength is greater than the maximum wind load (step S24A: No), the control device 15A returns to step S21A and provisionally determines the placement of the wall-connecting members WJ again (step S21A). In detail, the control device 15A modifies and provisionally determines the placement of the wall-connecting members WJ in the vertical direction so that the maximum bearing area obtained in step S22A is reduced. Specifically, as shown in FIG. 16, the placement of the wall-connecting members WJ is provisionally determined to be a height H1 of 5 meters from the ground and a position that is a predetermined dimension (for example, 10 centimeters) lower than a height H2 of 10 meters. As a result, the modified first-stage provisional position PT1' is provisionally determined to be a height H1' of 4 meters 90 centimeters from the ground, and the modified second-stage provisional position PT2' is provisionally determined to be a height H2' of 9 meters 90 centimeters from the ground.

[0107] The predetermined dimension is not limited to 10 centimeters. As long as the arrangement of the wall connector members WJ can be appropriately corrected, the predetermined dimension may be 5 centimeters or 20 centimeters. By setting the predetermined dimension to a dimension smaller than 10 centimeters, it becomes possible to finely correct the arrangement of the wall connector members WJ. On the other hand, by setting the predetermined dimension to a dimension larger than 10 centimeters, it is possible to shorten the processing time of the wall connector member vertical direction layout processing.

[0108] Next, the control device 15A again calculates the maximum bearing area of ​​the wall-connecting members WJ (step S22A). As described above, the area with the boundary line being the midpoint of the adjacent wall-connecting members WJ is set as the bearing area of ​​each wall-connecting member WJ, and the maximum value of the bearing area is calculated. As shown in FIG. 16, the area A12 has an area larger than the areas A11, A13, A21, A22, and A23. Therefore, the control device 15A calculates the area of ​​A12 as the maximum bearing area.

[0109] Next, the control device 15A calculates the maximum wind load again (step S23A) and judges whether the allowable strength of the wall-connecting member WJ is greater than the maximum load (step S24A). If it is not judged that the allowable strength is greater than the maximum wind load (step S24A: No), the process returns to step S21A, and a position that is a predetermined dimension lower is provisionally determined as the placement of the wall-connecting member WJ. Then, steps S21A to S24A are repeatedly executed until it is judged that the allowable strength of the wall-connecting member WJ is greater than the maximum wind load (step S24: Yes). This makes it possible to prevent the temporary scaffolding FT from collapsing while suppressing excessive placement of the wall-connecting member WJ in the vertical direction, thereby making it possible to suppress construction costs and reduce the construction burden on workers.

[0110] Returning to FIG. 13, the control device 15A outputs the horizontal arrangement of the wall connecting members WJ together with the exterior wall panel floor plan (step S14). The control device 15A also outputs the arrangement of the wall connection members WJ together with the exterior wall panel elevation (S14A). In detail, the control device 15A generates an image in which the horizontal and vertical arrangements of the wall connection members WJ are superimposed on the exterior wall panel elevation image, and outputs the image to the display device 12 of the wall connection member arrangement determination support terminal 10A. This makes it possible to easily grasp where on the exterior wall panel P the wall connection members WJ are to be attached, and it becomes possible to reduce the construction burden. The control device 15A may also transmit and output the image in which the arrangement of the wall connection members WJ is superimposed on the exterior wall panel elevation image to an external information processing device via the communication I / F 13. This makes it possible for a worker working on-site to easily grasp which of the multiple exterior wall panels P the wall connection members WJ are to be attached to, and it becomes possible to reduce the construction burden.

[0111] As described above, the wall-connecting member placement decision support terminal 10A can support the decision of the optimal placement of wall-connecting members in the horizontal and vertical directions. This makes it possible to reduce construction costs and construction burdens compared to the case where more wall-connecting members WJ are placed than necessary.

[0112] In the above-mentioned modified example, the vertical direction arrangement determining means 154A has been described as provisionally determining the arrangement of the wall-connecting members WJ, correcting the provisionally determined arrangement as necessary, and then determining the arrangement, but the method of determining the arrangement of the wall-connecting members WJ is not limited to this. The control device 15A may determine the vertical direction arrangement by calculating the maximum arrangement interval, similar to the case of determining the horizontal direction arrangement of the wall-connecting members WJ.

[0113] In the above-mentioned modified example, the arrangement of the wall connecting members WJ is superimposed on the exterior wall panel floor plan image and the exterior wall panel elevation image and output to the display device 12, but this is not limited to the above. The arrangement of the wall connecting members WJ may be superimposed on either the exterior wall panel floor plan image or the exterior wall panel elevation image and output to the display device 12.

[0114] In addition, in the above-described embodiment, it has been explained that the maximum placement spacing of the wall connecting members WJ is calculated based on the calculation formula and coefficients established by the Temporary Construction Industry Association of Japan, a general incorporated association; however, the calculation formula and coefficients may be updated or modified to appropriate ones as necessary.
