Description

  The present invention relates to an image system for explaining a building structure for visually explaining the safety of an earthquake-resistant structure and a base-isolated structure of a building using a three-dimensional image.

  In the structural design of a building, a structural plan that takes into account various forces such as fixed load, load load, snow load, wind pressure, seismic force, etc. that are always or temporarily applied to the building is required. In the structural design of a building, the shape of the building and the form of the skeleton are determined so as to satisfy the safety standards for various stresses caused by these various loads, and further, the arrangement and size of the building structural members are determined.

  A business owner of a building such as a condominium sold for sale is accountable for explaining to the buyer how the structure of the building is structured and safety.

  However, it is generally not possible for buyers who are not specialists to understand drawings and structural calculations of structures that are specialized fields of buildings.

  Therefore, Patent Document 1 proposes a strength display device for a building structure that expresses the strength determined based on the load and stress of the building structure member in an easy-to-understand manner on the actual building structure member displayed on the display screen.

  The contents include a storage means for storing shape data and relative position data of a plurality of types of building structural members, and a virtual three-dimensional model in which the building structural members are combined based on the data read from the storage means. 2D diagram creating means for creating and creating a 2D diagram drawn on a plane for a building structural member selected from the virtual 3D model and obtained by the 2D diagram creating means Display means for displaying a two-dimensional diagram on the display screen, stress calculating means for calculating a stress value based on stress calculation data corresponding to the attribute of each building structural member, and a two-dimensional diagram of the building structural member On the other hand, a plurality of different strength display modes are prepared in order from a small stress value to a large stress value corresponding to the band to which the stress value belongs for each building structural member, and obtained from the plurality of strength display modes by the stress calculation means. A selection screen for selecting a strength display mode corresponding to a band including the stress value, and a predetermined strength display mode selected by the selection unit as a strength display mode for a building structure member on a two-dimensional diagram It is the intensity display apparatus of the building structure which has an intensity display means to display on.

  However, in the apparatus disclosed in Patent Document 1, a two-dimensional diagram drawn on a plane is created and displayed on a building structure member selected from a virtual three-dimensional model obtained by combining the building structure members. It is displayed on the screen and the building structural member on the 2D diagram is expressed in the strength display mode according to the stress value, so that the strength of the actual building structural member can be visually understood. However, this is intended for architects and is not suitable as a tool for explaining the safety of the entire building to the buyer rather than whether the individual building structural members are safe.

  In order to explain to the buyer, who is generally an amateur, in an easy-to-understand manner, 3D (3D) indicates where and how the foundation, piles, beams, columns, earthquake-resistant walls, etc. of the building are located. It is thought that understanding is quick when it is explained using an image while rotating and enlarging the image.

  However, in order to display a 3D image using a PC (Personal Computer), it is necessary to install a special viewer or a 3D graphics description language on the PC or download it via the Internet. In addition, a 3D image generally has a large data size, and in order to display a complex and clean appearance at high speed, it is required that the processing speed of the CPU of the PC is high, so if a high-performance PC is not used, Image processing takes time, and it is difficult to reproduce images comfortably.

  In order to solve such a problem, Patent Document 2 discloses a Web 3D image display system capable of smoothly displaying a 3D image on a Web browser.

  This is a computer system that downloads a 3D image file from a server and displays a 3D image on a Web browser, and is described in a standard Web 3D graphics description language such as VRML (Virtual Reality Modeling Language). Editing / generation based on 3D scene information extracted from a Web 3D file, and displaying the 3D scene by executing a 3D compressed file of the 3D scene information obtained by editing / generation, real-time 3D rendering and motion algorithm A 3D applet for displaying 3D scenes, and a 3D applet for displaying 3D scenes and a Web browser for downloading 3D compressed files to display 3D scenes. Request a 3D applet 3D applet request means for downloading, 3D compressed file request means for executing a 3D applet to request and download a 3D compressed file from the server, and optional information such as scene, background, image, shape, texture, applet, toolbar, etc. Option information requesting means for requesting and downloading to a server, 3D applet executing means for executing 3D applet by a Web browser alone after completion of downloading and receiving all information, and 3D applet executing means Enables real-time 3D rendering and motion algorithms to be executed by a Web browser alone, and 3D scene display means for continuously displaying 3D scenes, displaying 3D scenes, and enabling interactivity with users That is Web3D image display system having an interactive display processing means.

  As described above, even if a client who wants to consider purchasing a condominium building such as an apartment is presented with a blueprint or structural calculation sheet for the building, the client does not know whether it is designed safely. . Moreover, even if it uses the intensity | strength display apparatus of a building structure as described in patent document 1, it is difficult to grasp | ascertain about the safety | security of the whole building.

  For developers such as condominiums, there is accountability to explain to the client what the structure of the condominium is like, and it is also purchased for clients to receive explanations about whether the safety of the earthquake-resistant structure is satisfied It becomes a big requirement.

  Specifically, the structure of piles, foundations, columns, beams, seismic walls, floors, etc., how long the piles are, whether the bending moment of the joints is okay, what the rebars are Explaining what's in the wind will give you a big judgment. In addition, by giving such explanations in an easy-to-understand manner, a sense of trust for developers such as condominiums is built.

  INDUSTRIAL APPLICABILITY The present invention is useful as a tool for fulfilling accountability to buyers such as condominiums, is easy to understand for clients, and can display 3D images smoothly on a Web browser on a PC. The purpose is to provide a system.

In order to solve the above-mentioned problems, the present invention uses a Web3D image display system disclosed in Patent Document 2 described above, and is easily understood by a client and can smoothly display a 3D image on a Web browser of a PC. It was developed as an explanatory image system.
The image system for explaining a building structure of the present invention is a page for explaining a building structure to a Web server connected to a PC via the Internet, an external memory directly connected to the PC, or an internal memory of the PC. Page data for displaying the image on the display, the data of the building structure to be displayed on the page, the page database storing the 3D applet page operation program, the compressed data of the engine for operating the Web 3D image display tool, and A 3D model database storing 3D screen display data, a texture database storing images for adding colors and textures to each element of a designated building structure, and a basic for moving a Web 3D image display tool Data flow in which a typical instruction is described in a 3D applet And an operation execution database in which a data file in which instructions for smoothly moving the 3D screen are described in a 3D applet are stored, and is described in the object-oriented language for the Internet on the PC. The 3D model database includes a 3D compressed file of 3D scene information and a 3D applet for executing real time 3D rendering and motion algorithms to display the 3D scene information. The pages configured and stored in the page database are described in html (HyperText Markup Language) format and 3D applet, and the images stored in the texture database are in general-purpose image formats such as gif, jpeg, etc. Features.
In the present invention, since no special viewer or three-dimensional graphics description language is used, an image can be displayed on a Web browser that is normally installed on a general PC, and 3D scene information is a compressed file. Since the 3D applet is used, the data size of the image can be reduced, the image processing can be performed at high speed, and comfortable image browsing is possible.
The page data may include at least one of frame configuration page data, possessed horizontal strength page data, panel zone, and structure page data. Panel zone and (steel) structure that is an area that receives a large shear force formed on a steel column beam joint, etc. on a PC web browser, possessed horizontal proof stress that indicates the position of the center of gravity and stiffness, and eccentricity, The structure of the frame, which is a frame part composed of beams, can be displayed in 3D, and can be displayed in an easy-to-understand manner by operations such as rotation, enlargement, and movement.
Here, the “center of gravity” is the center of weight of the building, and the “rigid” is the center of strength due to the arrangement of the seismic elements. When the building forms a collapse mechanism by the action of seismic force, the seismic force acts on the center of gravity of each floor of the building. This is resisted by the rigid core, which is the degree of resistance borne by the pillars, bearing walls and braces on each floor. “Eccentricity”, which is the degree of separation between the center of gravity and the rigid center, indicates the torsional rigidity of the building against the seismic force. If the eccentricity increases, the torsion of the entire building increases, and the balance is lost and the building tends to collapse. By displaying the center of gravity and the position of the rigid center of each floor in 3D on the Web browser, the earthquake resistance of the building can be easily understood.
As the 3D applet, a Java (registered trademark) applet can be used. Here, the “applet” refers to a simple module that can be used for programming an object-oriented language for the Internet such as Java (registered trademark).
The 3D scene information in the three-dimensional model database can be obtained by editing and generating based on 3D scene information extracted from a Web 3D file described in a Web 3D graphics description language.
VRML can be used as the Web 3D graphics description language. Here, VRML is a language for expressing a three-dimensional virtual space on the Internet Web, and can be output from many CAD (Computer Aided Design) and many CG (Computer Graphics) software. To reproduce with a Web browser, a dedicated plug-in is required, and a high-speed CPU is required. In the present invention, by creating 3D content as a Java (registered trademark) applet, a dedicated plug-in is not required.

According to the present invention, since no special viewer or three-dimensional graphics description language is used, an image can be displayed on a Web browser that is normally installed on a general PC, and 3D scene information is stored. Since it is stored as a compressed file and a 3D applet is used, the image data size can be reduced, image processing can be performed at high speed, and comfortable image browsing becomes possible.
Each frame portion is displayed in 3D on the panel zone and (steel frame) structure, which is a region that receives a large shearing force formed in the steel beam-column joint, etc., on a Web browser installed as standard on the PC. (Piles, foundations, columns, beams, floors, seismic walls) can be extracted and displayed, and operations such as rotation, enlargement, and movement can be performed to verify the overall frame structure of the building from all angles.
In addition, the structure of the frame, which is a frame part composed of pillars and beams, is displayed in 3D, and operations such as rotation, enlargement, and movement are possible, so that how the building pile or foundation is It can be displayed in 3D whether it is fixed on the supporting ground.
Furthermore, the retained horizontal proof stress indicating the position and eccentricity of the center of gravity and rigid center is displayed in 3D, and by allowing operations such as rotation, enlargement, and movement, the center of gravity and the rigid center are separated, so-called large eccentricity. You can verify the good balance of the building while confirming it.
