main control parameters of the steel bar truss floor support plate are as follows: the parameters mainly control the appearance and the size data of the model:
1. floor carrier plate bottom template size control parameters: "floor support plate bottom template length", "floor support plate bottom template width", "floor support plate bottom template thickness";
2. steel bar truss size control parameters: the upper chord rib diameter, the lower chord rib diameter, the web member rib diameter, the steel bar truss length, the steel bar truss spacing, the number of steel bar trusses, the steel bar truss side distance A and the steel bar truss side distance B;
3. and the association parameters of the steel bar truss and the bottom template are as follows: the thickness of the reinforcement protection layer, the dimension A of the reinforcement truss convex bottom plate and the dimension B of the reinforcement truss convex bottom plate.
Drawing control parameters of steel bar truss floor support plate: the method mainly comprises the steps of exportable processing parameters, drawing labeling parameters and visibility display parameters which are created according to deepened drawing requirements:
1. processing parameters can be derived: "L rebar" refers to "rebar truss length" above; "L-form" refers to the "floor deck bottom form length" above; "D" refers to the above "floor deck bed template width"; "a" refers to the "steel bar truss raised floor dimension a" above; "B" refers to the "steel truss raised floor dimension B" above; "e" refers to "steel truss edge distance A" above; "f" refers to "steel truss edge distance B" above; the "truss number" refers to the "number of steel bar trusses" above; "monolithic area" refers to the product of "steel bar truss length" and "floor form width" above;

3. visibility display parameters: the truss display parameter mainly plays a role in hiding the steel bar truss model in a plane view state, so that only the outline of the steel bar truss floor carrier plate and the drawing marking parameter are displayed when the drawing is output, and the drawing is more concise and clear on the premise of retaining the required information.
In the step S4, the following principles should be followed for splitting the structural floor model:

The steel bar truss floor support plate descending condition is used as a basis in the floor support plate splitting process, the part with the largest house type occupation ratio is preferentially detached and arranged according to the house type structure, and the descending plate area is firstly arranged if the descending plate part exists in the project. Under the conventional condition, the standard steel bar truss floor support plate comprises two steel bar truss spaces of 200mm and 300mm, and if the standard steel bar truss floor support plate is nonstandard, relevant parameters such as steel bar specifications, steel bar truss spaces and the like are required to be adjusted according to drawings or atlas requirements. In general, the bottom die length of the steel bar truss floor support plate is the span between two parallel steel beams, and the bottom die width of the steel bar truss floor support plate comprises four standard specifications of 600mm, 800mm, 900mm and 1200 mm.
The step S5 specifically comprises the following steps: and the exclusive two-dimensional code of the steel bar truss floor support plate is derived through a Revit software secondary development plug-in, and the two-dimensional code comprises two types of parameter information, namely the parameter for exportable processing and the map marking parameter. The required steel bar truss floor support plate arrangement model can be exported in batches and in layers through the functions of Revit software, and a size specification and engineering quantity detail table (shown in a table 1) can be used for early engineering quantity statistics and checking calculation, and in addition, constructors can accurately position and assist in installation of each component through scanning component two-dimensional codes; the construction exclusive two-dimensional code information generated in the Revit model can directly correspond to the floor support plate finished product plates produced by a processing plant, on-site constructors can assist in judging the positioning range and the plate orientation of each floor support plate by scanning the two-dimensional code on the steel bar truss floor support plate, and the problems of on-site plate positioning errors, orientation installation errors and the like can be effectively avoided.
