Fig. 2 illustrates a flow chart of a building model generation method according to an embodiment of the present disclosure, which starts at step S210.

In step S210, the floor model stored in the internal memory or the external memory may be imported into the system, or an engineer may create a floor model through the I/O device using the modeling function of the system. In this step, an environmental model, a fixed load, and a dynamic load may be applied to the floor model. And the model data parameters are inherited throughout the whole design process.

In step S220, a board descending area is constructed by the I/O device, the construction of the board descending area by the I/O device includes mouse selection construction or keyboard input construction, and when the mouse selects a construction mode, a point selected by the mouse directly reflects as a pixel coordinate on a screen, and the pixel coordinate, i.e., a coordinate of a user observation coordinate system, is required to be mapped to a local coordinate system coordinate in the floor slab model, so as to obtain an accurate corresponding relationship between the constructed board descending area and the floor slab model. When the floor model is input through the keyboard, a board descending area can be constructed in a virtual coordinate system, and then the virtual coordinate system is mapped to a local coordinate system of the floor model through three translation quantities and three angular quantities (x, y, z, alpha, beta and gamma), so that an accurate corresponding relation is generated.

In step S230, the relative distance between the lowering plate and the floor is input. It will be appreciated that the drop panel is a sunken structure on a floor. Thus, in the floor model, or in the model already loaded with the environmental model, the coordinates of the floor surface are smaller than the coordinates of the floor surface on the height axis.

In step S240, the processor causes the horizontal surface of the original floor slab model to generate a depression along the slab lowering area according to the selected slab lowering area and the relative distance between the slab lowering area and the floor slab, and the floor slab in the slab lowering area translates downward to form the slab lowering, thereby overcoming the defects that the existing method needs to delete the original structure and reestablish a new structure, and being capable of directly generating a model with the floor slab, the vertical slab and the slab lowering by using the existing floor slab model, thereby effectively reducing the workload of a designer and obtaining an accurate and effective design result.

It is noted that the virtual model can be directly generated after the floor slab model is built, and the environment model, the fixed load and the dynamic load are loaded to the virtual model. The virtual model can simulate the real environment and stress condition of the floor. And in the subsequent operation steps, the vertical plate is formed on the edge of the formed descending plate and the edge of the sunken part of the floor slab, and the vertical plate enables the floor slab and the descending plate to form a continuous surface method, so that inheritance is realized, the phenomenon that the attribute or the attribute change is deleted due to the change of the floor slab model is avoided, and the efficiency of generating a new model is saved. In the virtual model, the process of generating the descending plate and the vertical plate of the floor slab is displayed in a dynamic mode, and the intuition of the production process can be improved.

Of course, the generation of the virtual model after triggering the formation of the descending plate and the formation of the descending plate area can also meet the design requirements. It can be understood that in the process of generating the vertical plate, the floor slab and the descending plate with the continuous surface, the continuous surface enables the descending plate and the vertical plate to directly inherit the environmental model, the fixed load and the dynamic load loaded in the floor slab model. At this time, the virtual model is generated again, and the loaded environment model, the fixed load and the dynamic load do not need to be changed. The method of firstly triggering to form the descending plate and generating the virtual model after the descending plate area is formed reduces the operation difficulty of the processor and can effectively improve the design efficiency.

Further, the virtual model comprises elements such as floor coordinates, lines, attributes, models, names and the like. The model does not exist in the virtual model in a lightweight mode, and the floor model keeps more editing information, so that the requirement of further generating the lowering plate in the virtual model can be met, and the floor model generating the lowering plate well inherits the information of the original floor model.

Optionally, the thickness of the falling plate, the floor slab and the vertical plate is equal. Under general conditions, the same thickness of the descending plate, the vertical plate and the floor can meet design requirements, and the descending plate, the floor and the vertical plate are set to be equal by default. But the possibility that the lowering plate needs to carry a large force cannot be excluded. The present disclosure further provides an input interface, so that an engineer can independently specify load information of a plate lowering area according to design requirements, and at this time, the plate lowering area and the vertical plate may yield due to stress. The present disclosure also provides an interface to facilitate the engineer's custom in lowering the thickness of the board and in erecting the board. In a preferred embodiment, the thickness of the riser is 150mm or more. When the thickness of the vertical plate is 150mm, the vertical plate can effectively ensure that the landing plate has better bearing, can meet the load requirement of the design requirement of a general floor slab, and has better economy.

Further, methods for forming the board descending area include a mouse drawing method, a reference value method, a model reference point method and the like. The present disclosure will now be described with reference to figures 3-5 for the implementation of the above method.

The mouse drawing method mainly selects points on the model through a mouse, and then determines a board descending area. See fig. 3-4. The upper part of the floor slab model 10 is a plane, and the lower part is provided with a slab support 30. The slab support 30 is provided near the edge of the floor model 10 to provide support to the floor model as a whole 10. The middle of the floor model 10 is an area where the falling plate 20 needs to be disposed. The mouse selection method is adopted, and the mouse is required to be used for moving on a screen and performing selection. After the mouse picks up the coordinate point, the coordinate point needs to be mapped into the floor model coordinate system and associated with the floor model 10. The mouse sequentially selects points to form a closed graph, and the closed graph falls into a board area (figure 3). Because the manual point selection is adopted, the point selection has certain randomness, and the accuracy of the design cannot be guaranteed. Thus, an input interface is also provided, again defining the relationship of the touchdown area to the floor model. Typically, the projected point of the corner point of slab support 30 on the upper plane of the floor model is chosen as reference point 40. The 1 st coordinate point selected by the mouse is used as the base point 50. A two-dimensional coordinate system is established in the upper plane of the floor slab model with the reference point 40 as the origin. The distance from the base point 50 to the reference point 40 is entered to accurately determine the relationship of the drop floor area to the floor model. It is noted that the reference point 40 should be set at the corner point of the plate holder 30 at the lower left corner so that the translation value of the base point 50 with respect to the reference point 40 is positive. It will be appreciated that the rotation angle value δ can also be included to control the landing zone to produce a rotation angle correction. After the generation of the lowering plate function is started, the system automatically generates the lowering plate 20 and the vertical plate 60.

The preset model reference point method has similarity with the mouse drawing method. The predetermined model comprises the base points 50 and the model parameters, and the lowering plates of the floor slab model of fig. 3-4 can also be generated using the predetermined model reference point method. The preset model reference point method comprises a preset model rule base, wherein the model rule comprises forming rules such as circles, squares, regular polygons and the like. And provides modifiable parameter values to facilitate an engineer adjusting the shape or size of the landing area. Taking fig. 3 as an example, the model rule base includes a flat area for generating a square. The 4 sides of the square are perpendicular to each other. The designer only needs to input the specific side lengths of the 4 sides to determine the size and shape of the panel dropping area. Further, the engineer needs to strictly correspond the slab descending area to the floor slab model through the reference point 40 and the base point 50. An engineer can select a reference point 40 on the floor slab model 10 through a mouse, and can also use a corner point of the left lower corner plate support 30 as the reference point 40, so that the position of the closed graph on a plane for generating the falling plate is determined, and the falling plate is generated according to the determined closed graph. Similarly, the rotation angle value delta can be included so as to control the landing area to generate rotation angle correction.

When a circular model rule is adopted, the center of the circle is generally used as the base point 50. The engineer only needs to input the radius of the circular falling plate, and the size of the circular falling plate can be determined according to a circular formula.

Referring to numerical method, it is necessary to generate a plane of the falling board, and determine a coordinate point of the falling board P1 (see fig. 5) by using a mouse or a coordinate input method. The reference numerical method is generally applied to a step-down plate design of irregular polygons. The platedropping region has n coordinate points in common, denoted as { Pi | i =1, 2, … … k … … n-1, n }. With P1 generally serving as the base point 50. And on the k-1 coordinate point, establishing a coordinate system by taking the k coordinate point as an origin, inputting the coordinate value of the k coordinate point under the coordinate system formed by the k-1 coordinate point, forming a closed graph by the n coordinate points to be a board descending area, and determining the size and the shape of the board descending area.

Subsequently, a reference point is determined on a plane on which the descending board needs to be generated through a mouse or a coordinate input method, a coordinate system is established by taking the reference point as an origin, and under the coordinate system established by taking the reference point as the origin, the coordinate value of the P1 coordinate point relative to the reference point 40 is input, so that the position of the closed graph on the plane on which the descending board is generated is determined, and the descending board is generated according to the determined closed graph.

and an information display unit capable of performing the step of S210, and building and displaying the floor slab model.
