Description
Technical Field
The invention belongs to the technical field of building modeling, and particularly relates to a method for modeling and calculating a light wood structure wall body frame based on a Rhino Inside Revit.
Background
The light wood structure is a single-layer or multi-layer building structure consisting of a wood frame wall body made of standard materials, wood-based structural plates or gypsum boards, a floor slab and a roof system, and compared with concrete and steel structures, the light wood structure system has certain advantages in the aspects of energy conservation and heat preservation, economy, carbon sequestration and emission reduction, construction efficiency and the like. The light wood structure wall frame is formed by connecting and combining wood components such as top beam plates, bottom beam plates, floor beam plates, through long wall skeleton columns, cross braces and the like which are made of specification materials through nails.
In the prior art, chinese patent publication No. CN114756935a discloses a light steel keel partition parametric modeling method and system based on rhino. Data of a target wall body needing to generate a light steel keel partition wall in the reference model is picked up by using various calculators to obtain arrangement points of corresponding top and bottom keels, vertical keels and transverse keels; according to the reference plane of the parameterization family of the parameterization component, endowing a three-dimensional working plane corresponding to each arrangement point; and calling a parameterization family to establish a model of the top keel, the bottom keel, the vertical keel and the transverse keel.
The prior art has the defect that the modeling method aims at the light steel keel partition wall, and the light steel keel partition wall and the light wood structure have different mechanical properties and different compliance specifications, so the scheme cannot be directly applied to the building of the light wood structure wall. The method specifically comprises the following steps: because the mechanical properties of steel and wood are different, the structural arrangement regulations of two wall frames are greatly different in the national specification, the difference is reflected not only in different naming modes and section shapes of components at the same position, but also in a reinforcing mode of structures around a hole, for example, an additional transverse keel and an additional vertical keel are required to be added at the door and window hole of a light steel keel partition wall, and components such as a door and window hole lintel and a support column are required to be additionally added at the door and window hole of a light wood structure wall according to the size of the hole.
In the prior art, a related automatic modeling plug-in for a light wood structure building structure frame (specifically, a plug-in for an automatic modeling for a light wood structure building structure frame V1.0 "in a chinese software copyright" 2018SR 427576) also exists, and the plug-in is manufactured by a visual programming platform Dynamo. The insert has the following disadvantages: first, the threshold for using the insert is high, which is not conducive to being generalized among construction engineers. The method specifically comprises the following steps: for the construction engineer, the platform is unfamiliar, and the use of the plug-in has a high threshold, and a certain amount of effort is required to learn the basic operations of Dynamo. Secondly, the insert is less flexible to use. The method specifically comprises the following steps: the plug-in has the advantages that the main input end of the plug-in is structural design parameters, the modeling result is changed according to the change of the input parameters, the real-time visual modification and adjustment of the modeling result through a 'dragging' command at the Revit using end are not supported, and the flexibility of the use of software is poor.
Therefore, the technical problems of high use threshold and poor use effect exist in the existing light wood structure wall body frame modeling scheme.
