Description

The present invention relates to a crane planning support system that selects a crane for a building model to be constructed using BIM.

Various types of cranes used at construction sites have different lifting ranges depending on boom lengths, different loads that can be lifted, and the like. For this reason, it is necessary to select a crane suitable for construction when drawing up a construction plan for a building. In the past, cranes were selected manually by the person in charge of selection based on the information in the blueprints of the building to be constructed. For this reason, the person in charge of selection is required to have advanced skills based on knowledge and experience. Therefore, it is desired to make the work of selecting a crane easier.

On the other hand, for example, Patent Document 1 discloses a configuration for determining whether or not a lifting member model can be lifted by the crane model based on information on the turning center position of the crane model and information on the movement source position and the mounting destination position of the lifting member model having weight information, and displaying a selectable boom length for the crane model.
In the configuration disclosed in Patent Document 1, although the boom length of the crane that can be selected is displayed, the specific crane model is not presented, and ultimately the crane model must be selected by the person in charge of selection.

In addition, Patent Document 2 discloses a configuration that uses BIM (Building Information Modeling) technology to verify the virtual operation of equipment such as a crane placed at a construction site in a computer device with respect to a digital model of a building.
The configuration disclosed in Patent Document 2 does not select a crane model suitable for construction work.

Further, Patent Literature 3 discloses a configuration for determining the possibility of erection by multiple types of cranes for each member of the skeleton when planning the erection of the skeleton based on the three-dimensional skeleton drawing.
In the configuration disclosed in Patent Document 3, although the possibility of erection by multiple types of cranes is determined for each structural member, the specific model of the crane is not presented, and ultimately the person in charge of selection must select the model of the crane.

The present invention relates to a crane planning support system capable of automatically selecting visually optimum cranes by using BIM (3D attributed building model) instead of 2D building blueprints. The crane planning support system determines a lifting range and a crane position for a building model at each construction stage, automatically extracts a crane capable of lifting members within the lifting range, and selects and inputs an optimum crane to be used from among the automatically extracted cranes.
EMBODIMENT OF THE INVENTION Hereinafter, with reference to an accompanying drawing, the form for implementing the crane plan support system by this invention is demonstrated based on drawing.
FIG. 1 shows a block diagram showing the functional configuration of the crane planning support system according to this embodiment.
The crane planning support system 1 shown in FIG. 1 determines a lifting range and a crane position for a building model to be constructed using BIM, and selects a crane. Here, BIM is to support the design, construction, etc. of a building by using a building database in which a three-dimensional building model is associated with member information such as the weight, dimensions, and materials of the members that make up the building. The crane planning support system 1 is implemented using a computer device, and includes a model data storage unit 2, a database 3, a model processing unit 4, a crane extraction processing unit 5, and model display means 6.

The model data storage unit 2 stores data for constructing a building model based on building design data, a construction site model representing a construction site, a crane model having a crane body and a lifting boom, and the like. The building design data includes attribute information of members such as positions, dimensions, materials, and positions of the center of gravity of the members that constitute the entire building. A building model is formed by modeling an entire building based on building design data. Also, a building is constructed step by step through a plurality of stages of construction processes (work zones) during construction. The building model includes attribute information of members constructed for each construction section. A construction site model is a model of a construction site and its surrounding environment.
A database 3 records the crane performance of a plurality of cranes. The crane performance of each crane recorded in the database 3 includes, for example, the name and model name of the crane for identifying the crane, the rated load of the crane, the working radius, the dimensions of the crane body, the dimensions of the boom provided on the crane body, and the like.
The model processing unit 4 causes the model display means 6 to display the building model, building site model, crane model, etc. stored in the model data storage unit 2 based on the stored data.

The crane extraction processing unit 5 includes automatic crane extraction means 51 and input means (crane selection input means) 52 .
The crane automatic extraction means 51 automatically extracts cranes applicable to given conditions by automatically executing processing based on a preset computer program. The automatic crane extraction means 51 calculates the weight of the members constituting the building model within the lifting range and the working radius of the crane when the lifting range and the crane position are given (designated) as conditions for the building model displayed on the model display means 6. The automatic extraction means 51 of the crane calculates the weight and the center-of-gravity position of the members within the lifting range from the attribute information of the members forming the building model within the lifting range. The automatic crane extraction means 51 compares each calculated value of the weight of the member constituting the building model and the working radius of the crane within the lifting range with each of the crane performances in the database 3, and automatically extracts the crane having the rated load and working radius that can lift the member within the lifting range.
The input means 52 consists of input devices for the computer device such as a mouse and a keyboard, and receives input regarding the selection of the crane to be finally used from among the cranes automatically extracted by the crane automatic extraction means 51 .

The model display means 6 consists of a display device such as a monitor. Model display means 6 displays a building model, a building site model, a crane model, etc. in a three-dimensional virtual space based on the data output from model processing section 4 . Further, when a member within the lifting range is selected, the model display means 6 displays the weight of the member and the working radius of the crane. The model display means 6 displays information about cranes automatically extracted by the crane extraction processing section 5 . The model display means 6 displays the crane performance of the selected crane when an input means selects an arbitrary crane from the cranes automatically extracted by the crane automatic extraction means 51.例文帳に追加

Next, the flow of the crane selection process in the crane planning support system 1 will be described.
FIG. 2 shows a flowchart showing the flow of crane selection processing in the crane planning support system according to the present embodiment. FIG. 3 is a diagram showing an example of a display screen for setting the load calculation coefficient of the suspended load.
As shown in FIG. 2, in the crane selection process in the crane planning support system 1, first, the crane automatic extraction means 51 receives the setting of the load calculation coefficient of the suspended load (step S1). For this purpose, as shown in FIG. 3, the crane automatic extraction means 51 causes the display screen of the model display means 6 to display an input screen G1 for each coefficient. The person in charge of selection uses the input means 52 to input the coefficients used when the crane planning support system 1 calculates the lifting load of each member in the subsequent selection process into the input fields on the input screen G1. For example, as load calculation coefficients for a suspended load, the person in charge of selection inputs a steel frame weight coefficient (e.g., 1.5) when the member is a steel frame, a PCa weight coefficient (e.g., 2.5) when the member is PCa (precast concrete), a weight (e.g., 0) of a hanging jig for suspending the PCa member, and a safety coefficient (e.g., 80).
The automatic extraction means 51 of the crane stores the set load calculation coefficient of the suspended load.

FIG. 4 is a diagram showing an example of a display screen for setting a lifting range.
Next, the automatic extraction means 51 of the crane receives the setting of the lifting range, which is the range in which the member is lifted by the crane (step S2). For this purpose, the crane automatic extraction means 51 causes the display screen of the model display means 6 to display a lifting range setting screen G2. In order to set the lifting range, the person in charge of selection inputs the range in which the member is to be lifted by the crane in the X direction in the horizontal plane, the Y direction orthogonal to the X direction in the horizontal plane, and the level (height) in the vertical direction, using the input means 52, in the lifting range setting screen G2.
Here, as described above, a plurality of construction processes (work zones) are set for constructing a building. When a crane is selected for each work zone, the lifting range set in step S2 is the range in which the members to be constructed in that work zone are arranged.
FIG. 5 is a diagram showing an example of a display screen showing a set lifting range. As shown in FIG. 5, the crane automatic extraction means 51 can superimpose the lifting range A1 set in step S2 on the three-dimensional models of the building model M1 and the construction site model M2 retrieved from the model data storage unit 2 by the model processing unit 4, and display them on the model display unit 6.

FIG. 6 is a diagram showing an example of a list screen of members positioned within the set lifting range.
Furthermore, the automatic extraction means 51 of the crane refers to the model data storage unit 2, and automatically searches and acquires information such as the type, purpose, number, weight, total weight, etc. of all members located within the set lifting range A1 (step S3). The automatic crane extraction means 51 displays on the display screen of the model display means 6 a list screen G3 of members within the obtained lifting range A1. The person in charge of selection visually checks the list screen G3 to check whether the set lifting range A1 is correct. If there is an error in setting the lifting range A1, the setting of the lifting range in step S2 is redone.

FIG. 7 is a diagram showing an example of a screen for setting the position of the crane. FIG. 8 is a diagram showing an example of a screen for designating the farthest suspended load from the position of the crane. FIG. 9 is a diagram showing an example of a confirmation screen for the farthest suspended load.
Next, the crane automatic extraction means 51 receives designation of a position for setting a crane (step S4). For this, the person in charge of selection designates the position P1 where the crane is to be installed on the construction site model M2 displayed on the model display means 6 using the input means 52 . Then, the crane automatic extraction means 51 stores the designated crane position P1.
Further, in step S4, the designation of the suspended load that is farthest from the crane arranged at position P1 within the lifting range A1 is accepted. For this, the person in charge of selection uses the input means 52 to specify the position P2 of the member (suspended load) farthest from the crane placed at the position P1 on the building model M1, as shown in FIG. Then, the crane automatic extraction means 51 displays a confirmation screen G4 showing information about the specified member, as shown in FIG. The person in charge of selection visually checks the confirmation screen G4 to confirm whether or not the specified member is correct. After confirmation by the person in charge of selection, the automatic extraction means 51 of the crane stores the member placed at the designated position P2 as the load farthest from the crane.

FIG. 10 is a diagram showing an example of a crane list screen in which installable cranes are automatically extracted.
Next, the crane automatic extraction means 51 automatically extracts cranes that can be installed at the position P1 (step S5). The automatic crane extraction means 51 refers to the crane performance of each crane stored in the database 3, and automatically extracts cranes having crane performance capable of lifting all members (suspended loads) within a lifting range A1 including the member farthest from the crane arranged at position P1, that is, having crane performance capable of being installed at position P1.
The crane automatic extraction means 51 displays a crane list screen G5 on the display screen of the model display means 6 . The person in charge of selection selects the crane type, boom type, crane size, etc. on the crane list screen G5 using the input means 52 . Then, as shown in FIG. 10, the automatic crane extraction means 51 displays, on a crane list screen G5, a list L1 of cranes that match the crane type, boom type, crane size, etc. specified by the person in charge of selection among the cranes that can be installed (arranged) at the automatically extracted position P1. List L1 describes "(crane size) crane name (main boom standard)" of a plurality of cranes that can be installed (arranged) at position P1. This list L1 is, for example, listed in descending order of crane size.

The person in charge of selection selects any one crane from the list L1 of the crane list screen G5 using the input means 52 (step S6). Then, the crane automatic extraction means 51 displays the appearance image L2 of the crane selected on the list L1, the information L3 indicating the crane performance, the information L4 regarding the suspended load within the lifting range A1, etc. on the crane list screen G5. Here, the information L3 indicating the crane performance includes, for example, the name of the crane, the size of the crane, the standard of the main boom, the angle of the main boom (the boom angle when lifting the farthest suspended load), the jib standard, the jib angle (the jib angle when lifting the farthest suspended load), and the like. In addition, as the information L4 on the hoisted load within the lifting range A1, for example, the maximum working radius (working radius when lifting the farthest hoisted load, rated load (rated load of the above working radius), hook weight (hook weight for rated load), lifting capacity ((rated load - hook weight) x safety factor), member weight (weight of the farthest hoisted load), working radius (working radius for lifting the heaviest hoisted load), hook weight (hook weight for rated load), maximum member weight (weight of the heaviest suspended load), etc.

FIG. 11 shows an example of a display screen displaying automatically extracted cranes together with a building model and a construction site model.
Next, as shown in FIG. 11, the automatic crane extraction means 51 calls the crane model M3 corresponding to the crane selected by the person in charge of selection from the list L1 from the database 3, arranges it in the three-dimensional virtual space on the display screen of the model display means 6, and displays it together with the building model M1 (step S7). At this time, it is assumed that the crane model M3 has a crane main body 101 and a lifting boom 102 .
A person in charge of selection visually observes the crane model M3 displayed on the display screen of the model display means 6 and the building model M1, and confirms whether the crane model M3 installed at the position P1 interferes with the building model M1 or the construction site model M2. As a result, if the crane model M3 interferes, another crane is reselected from the list L1 shown in FIG.
When it is confirmed that the crane model M3 does not interfere with the building model M1 or the construction site model M2, the crane selection process ends.

The above-described crane selection process described with reference to FIG. 2 is individually executed in each of a plurality of construction stages in construction of a building whose construction plan is drawn up by the crane plan support system 1 .
For example, a building can be divided into a plurality of construction zones in a plan view during construction, and construction can be managed for each construction zone. Also, even within the same construction section, portions of the building located within the construction section are divided into construction blocks at predetermined heights, and construction can be managed for each of these construction blocks.
In such a case, the building construction plan is subdivided into construction stages for constructing each of these parts corresponding to each construction section or each construction block. By executing the construction stages one by one or in parallel, the building is constructed by sequentially constructing the parts corresponding to each construction stage. For example, when drawing up a construction plan for a building using the crane planning support system 1, as the first construction stage, the construction plan for the construction block located at the bottom in a certain construction section can be formulated, and then the construction plan for the construction block located one block above the construction block can be formulated as the second construction stage. After that, as a third construction step, a construction plan for a construction block located one level above can be drawn up. Alternatively, the construction plans for the portions located within one construction section may be grouped together and associated with one construction stage.
In the above-described crane planning support system 1, at each construction stage, the above-described crane selection process is executed for a portion of the building to be constructed at that construction stage.

The crane planning support system 1 as described above is a crane planning support system 1 that determines a lifting range and a crane position for a building model to be constructed using BIM, and selects a crane. An automatic crane extraction means 51 for automatically extracting a crane capable of lifting a member within the lifting range A1, and a crane selection input means 52 for receiving an input regarding the selection of a crane to be finally used from among the automatically extracted cranes.
According to such a configuration, the automatic crane extraction means 51 calculates the weight of the member and the work radius of the crane within the lifting range A1 of the crane at the designated crane position, and compares each calculated value with the crane performance of each of the plurality of cranes, thereby automatically extracting the crane that can lift the member within the lifting range A1. In this manner, the crane planning support system 1 automatically extracts a suitable crane based on the lifting range A1 and the crane layout plan. As a result, the person in charge of selection can judge and select the crane to be finally used from among the automatically extracted cranes, and input it to the crane selection input means 52 . Therefore, it is possible to easily select a crane to be used when drafting a building construction plan.

In particular, in this embodiment, the automatic crane extracting means 51 automatically extracts, at each construction stage of a building, a crane capable of lifting a member related to a building portion to be constructed at that construction stage.
According to such a configuration, the crane planning support system 1 designates a lifting range and a crane position for each construction section or construction block unit that constitutes the building model M1 based on the building construction planning procedure, and can select a crane capable of lifting members within the lifting range. Therefore, it is possible to formulate a detailed crane plan based on the construction plan of the building.

In addition, the crane performance includes the rated load and working radius of the crane, and the automatic crane extraction means 51 calculates the weight and the center of gravity of the member within the lifting range from the attribute information of the member, and automatically extracts the crane having the rated load and working radius that can lift the member within the lifting range.
According to such a configuration, the automatic crane extraction means 51 automatically extracts a crane having a rated load and working radius capable of lifting a member within the lifting range based on the weight of the member within the lifting range and the position of the center of gravity. Thereby, a crane can be selected with higher accuracy.

When a member within the lifting range is selected, the model display means 6 displays the weight of the member and the working radius of the crane, and when an arbitrary crane is selected from the cranes automatically extracted by the automatic crane extraction means 51, the crane performance of the crane is displayed.
According to such a configuration, the weight of the member within the lifting range and the crane performance of the automatically extracted crane can be compared and confirmed on the display on the model display means 6 .
