Description

Modeling and Calculation of Light Timber Wall Frame Based on Rhino Inside Revit Methods

technical field

The invention belongs to the technical field of building modeling, and in particular relates to a method for modeling and calculating a light wood structure wall frame based on Rhino Inside Revit.

Background technique

Light wood structure refers to a single-story or multi-storey building structure composed of wooden frame walls, floor slabs and roof systems made of standard timber and wood-based structural panels or gypsum boards. Compared with concrete and steel structures, light wood structure systems It has certain advantages in terms of energy saving and heat preservation, economy, carbon sequestration and emission reduction, and construction efficiency. The light-weight wood structure wall frame is composed of top beams, bottom beams, ground beams, full-length wall studs, cross braces and other wooden components made of standard timber through nail connection.

In the prior art, Chinese Patent Publication No. CN114756935A discloses a method and system for parametric modeling of light steel keel partition walls based on Rhino.Inside.Revit. In the method, parametric components required for parametric modeling are configured, and light The reference plane corresponding to the placement of each parameterized component in the steel keel; use various calculators to pick up the data of the target wall that needs to generate the light steel keel partition wall in the reference model, and obtain the corresponding sky and earth keel, vertical Layout points of keels and horizontal keels; according to the reference plane of the parametric family of parametric components, assign the corresponding three-dimensional work plane to each layout point; call the parametric family to establish the model of the heaven and earth keel, vertical keel and horizontal keel .

The disadvantage of this existing technology is that the object of this modeling method is a light steel keel partition wall, and the mechanical properties and the codes to be complied with of a light steel keel partition wall and a light wood structure are different. Therefore, this scheme cannot be directly applied to create a lightweight Wood structure wall. Specifically: due to the different mechanical properties of steel and wood, the structural layout of the two wall frames in my country's codes is also quite different. This difference is not only reflected in the different naming methods and cross-sectional shapes of the components at the same position, but also in the openings. In terms of the strengthening method of the surrounding structure, for example, the light steel keel partition wall needs to add additional horizontal and vertical keels at the door and window openings, and the light wood structure wall needs to add additional components such as door and window opening lintels and support columns at the door and window openings according to the size of the opening. The parametric modeling method developed in the prior art for the specification of light steel keel partition walls cannot be directly applied to create light wood structure walls, and the two cannot be generalized.

In the prior art, there is also a related plug-in for automatic modeling of light-weight wooden building structure frame (specifically, China Software Copyright ""2018SR427576 Automatic Modeling Plug-in for Light-weight Wooden Building Structure Frame V1.0"). The visual programming platform used by this plug-in Produced by Dynamo. The disadvantages of this plug-in are: firstly, the threshold for using this plug-in is high, which is not conducive to popularization among construction engineers. Specifically: for construction engineers, the platform is relatively unfamiliar, and there is a high threshold for using this plug-in. It takes a certain amount of energy to learn the basic operations of Dynamo. Secondly, the flexibility of the plug-in is poor. Specifically: the main input of the plug-in is the structural design parameters, and the modeling results change according to the changes of the input parameters, which does not support On the Revit user side, the real-time visual modification and adjustment of the modeling results through the "drag and drop" command, the flexibility of the software is poor.

Therefore, there are technical problems in the existing light-weight wood structure wall frame modeling scheme that the threshold for use is high and the use effect is not good.
