FIG. 3 is a schematic diagram of a second embodiment of the present invention.
As shown in fig. 3, the projections of the target member on the initial cavity wall, namely, the third drop leg 303, the fourth drop leg 304, the fifth drop leg 305, and the sixth drop leg 306 form a closed rectangle, and in practice, the projections of the target member on the initial cavity wall can be determined as follows:

The center point of the bounding box of the target member may then be determined, the center point of the bottom surface of the target member may be determined based on the center point of the bounding box of the target member, the perpendicular lines may be drawn to the two surfaces through the center point of the bottom surface of the target member, the first and second feet 301 and 302 may be drawn to the initial cavity wall through the first and second feet 301 and 302, respectively, and the third and fourth feet 303 and 304 may be drawn through the feet, respectively.
And a vertical line is respectively drawn to the top surface of the target member by a third drop foot 303 and a fourth drop foot 304, the drop feet are a fifth drop foot 305 and a sixth drop foot 306 respectively, and the third drop foot 303, the fourth drop foot 304, the fifth drop foot 305 and the sixth drop foot 306 are connected to form a closed rectangle, namely, the projection of the target member on the initial cavity wall body is the connection area of the target member and the initial cavity wall body.
According to the wall splitting method, the initial cavity wall body can be generated based on the target wall body in the building information model, wherein the initial cavity wall body is the target wall body with the cavity, then the target component connected with the initial cavity wall body in the building information model can be determined based on the bounding box of the initial cavity wall body, and the initial cavity wall body can be cut based on the projection of the target component on the initial cavity wall body.
In an exemplary embodiment, generating an initial cavity wall based on a target wall in a building information model includes:
determining a positioning axis of a target wall;
and generating an initial cavity wall body based on the positioning axis and the thickness of the cavity, wherein the positioning axis of the cavity coincides with the positioning axis of the target cavity wall body.
Fig. 4 is a schematic structural diagram of a target wall according to an embodiment of the present invention.
The positioning axis is a line for determining the structural position of a member in the building field, and correspondingly, as shown in fig. 4, the positioning axis 401 of the target wall body is a central line in the extending direction of the target wall body, so that an initial cavity wall body can be generated based on the positioning axis 401 of the target wall body.
In this embodiment, the initial cavity wall body can be generated by cutting the target wall body based on the positioning axis of the target wall body, and the positioning axis of the cavity in the generated initial cavity wall body can coincide with the positioning axis of the target cavity wall body, so that the cavity is located at the center of the initial cavity wall body, and the thicknesses of the first wallboard and the second wallboard in the initial cavity wall body are consistent, and the accuracy of wall body splitting is effectively improved.
In an exemplary embodiment, determining a target component connected to an initial cavity wall in a building information model based on a bounding box of the initial cavity wall comprises:
determining bounding boxes of the initial cavity wall body and bounding boxes of all other components except the target wall body in the building information model;
determining an external expansion bounding box of the initial cavity wall body based on the bounding box of the initial cavity wall body;
and if the bounding boxes of the other components overlap with the flaring bounding boxes, determining the other components as target components.
In implementation, bounding boxes can be built for the initial cavity wall body and all other components in the building information model, so that bounding boxes of all other components are obtained, and if the bounding boxes of the initial cavity wall body are overlapped with the bounding boxes of other components, other components are determined to be target components, namely, the initial cavity wall body is connected with the initial cavity wall body.
In practical application, because the target component may intersect with the initial cavity wall body and may also be tangent to the initial cavity wall body, if the target component is tangent to the initial cavity wall body, the bounding box of the initial cavity wall body may also be tangent to the bounding box of the target component, so that the target component may not be determined only based on the bounding box of the initial cavity wall body and the bounding boxes of other components, based on this, the flared bounding box of the initial cavity wall body may be determined based on the initial cavity wall body, and the target component may be accurately determined through the flared bounding box of the initial cavity wall body under the conditions that the other components are tangent to the initial cavity wall body and the bounding box of the initial cavity wall body is also tangent to the bounding box of other components, so that the efficiency and the accuracy of wall body splitting can be effectively improved.
Illustratively, determining the flared bounding box of the initial cavity wall based on the bounding box of the initial cavity wall may include: and determining the expansion bounding box of the initial cavity wall body based on the bounding box of the initial cavity wall body and a preset tolerance value.
The tolerance value may be a thickness of the expanded bounding box of the initial cavity wall compared to the bounding box of the initial cavity wall, and exemplary tolerance values may be 10 millimeters, that is, the expanded bounding box of the initial cavity wall may be 10 millimeters compared to the bounding box of the initial cavity wall.
In an exemplary embodiment, an initial cavity wall includes a first wall panel and a second wall panel, a target member includes a first floor panel connected with the first wall panel and a second floor panel connected with the second wall panel, the initial cavity wall is cut based on a projection of the target member onto the initial cavity wall, and a target cavity wall is generated, including:
cutting the first wallboard based on the projection of the first floor slab in the vertical direction of the first wallboard;
and cutting the second wallboard based on the projection of the second floor slab in the vertical direction of the second wallboard to obtain the target cavity wall.
In practice, the target member may be a floor slab.
As described above, in practical application, the initial cavity wall body not only has a cavity, but also includes the first wall board and the second wall board on the left and right sides of the cavity, based on which the floor slab connected with the initial cavity wall body can be divided into the first floor slab connected with the first wall board and the second floor slab connected with the second wall board, for the first floor slab and the second floor slab, in the process of cutting the initial cavity wall body based on the projection of the floor slab on the initial cavity wall body, only the first wall board connected with the first floor slab, or only the second wall board connected with the second floor slab, that is, based on the projection of the first floor slab on the vertical direction of the first wall board, and based on the projection of the second floor slab on the vertical direction of the second wall board, the second wall board can be cut.
In this embodiment, the target member may be a floor slab, and the floor slab connected with the initial cavity wall body is divided into the first type floor slab and the second type floor slab according to the structure of the initial cavity wall body, and in the process of cutting the initial cavity wall body, the first wall board or the second wall board can be cut based on whether the floor slab type is the first type floor slab or the second type floor slab, so that the split target cavity wall body and the target member are more compatible, and the accuracy of wall body splitting is improved.
In the exemplary embodiment, although the initial cavity wall needs to be connected to the upper floor slab and the lower floor slab, since the lower floor slab is the upper floor slab of the wall body of the next floor at the same time, only the upper floor slab connected to the initial cavity wall body can be determined when determining the floor slab connected to the initial cavity wall body, so that all floor slabs connected to the initial cavity wall body can be determined when disassembling the wall body of each floor of the building. Therefore, the operation steps can be simplified, and the wall splitting efficiency is improved.
In an exemplary embodiment, the target member comprises a beam, cutting the initial cavity wall based on a projection of the target member onto the initial cavity wall, generating a target cavity wall, comprising:
And cutting the initial cavity wall based on the projection of the positioning axis of the beam in the vertical direction of the initial cavity wall to obtain the target cavity wall.
In practice, the target member may be a beam in a building, in which case the initial cavity wall may be cut in the same manner as the floor slab, that is, the beam is divided into a first type beam connected to the first wall plate and a second type beam connected to the second wall plate, projections of the first type beam and the second type beam in the vertical directions of the first wall plate and the second wall plate of the initial cavity wall are determined, and then the first wall plate and the second wall plate are cut. However, in practical application, the beams and the wall body are in an intersecting relationship, and the beams are necessarily penetrating through the wall body, and the condition that the first wall board and the second wall board of the wall body are respectively connected with different beams cannot exist, so that the types of the beams can be directly cut on the initial cavity wall body based on the projection of the beams on the vertical direction of the initial cavity wall body without distinguishing, and specifically, the projection part of the beams on the initial cavity wall body can be directly cut off.
In practice, the beam size in the building information model is generally fixed, so that the beam position can be determined by determining the projection of the positioning axis of the beam in the vertical direction of the initial cavity wall, then determining the projection of the beam in the vertical direction of the initial cavity wall based on the preset beam size, and further cutting the initial cavity wall based on the projection.
In this embodiment, the target component can be the roof beam, can confirm the projection of roof beam on initial cavity wall body through the projection of the location axis of roof beam on initial cavity wall body vertical direction, and then can cut initial cavity wall body, so, can be more accurate and more simple and convenient confirm the projection of roof beam on initial cavity wall body, can improve the efficiency and the accuracy of wall body split.
In an exemplary embodiment, the projection of the target member onto the initial cavity wall is a first connection area of the target member and the initial cavity wall, and the initial cavity wall is cut based on the projection of the target member onto the initial cavity wall to generate the target cavity wall, including:
extending the vertical width of the first connecting area by a first set distance to obtain a second connecting area;
and cutting the initial cavity wall based on the second connection area to obtain the target cavity wall.
Because the target cavity wall body obtained through cutting is spliced with the target component in the actual installation process, if the initial cavity wall body is cut only based on the projection of the target component on the initial cavity wall body, the component seam cut on the initial cavity wall body is exactly consistent with the contour of the component, if the surface of the target component and the surface of the component seam on the target cavity wall body are not smooth enough, the target component and the target cavity wall body can not be normally connected, based on the fact, a first connecting area corresponding to the projection of the target component on the initial cavity wall body can be extended to a certain extent in advance to obtain a second connecting area, and then the initial cavity wall body is cut based on the second connecting area, so that the installation process of the target component and the target cavity wall body can be smoothly carried out, and in practical application, the extended area can be filled after the installation of the target component and the target cavity wall body is completed.
In implementation, the vertical width of the first connection area may be extended to obtain the second connection area, and an exemplary vertical width of the first connection area may be extended by a first set distance, and an exemplary value of the first set distance may be 50 millimeters.
In this embodiment, the vertical width of the first connection area between the target member and the initial cavity wall is extended by the first set distance, so that a second connection area slightly larger than the first connection area is obtained, and then the initial cavity wall is cut based on the target connection area, so that the obtained target cavity wall and the target member are connected more easily.
In an exemplary embodiment, further comprising: cutting the bottom of the initial cavity wall body by a second set distance.
In the building, the target member connected with the initial cavity wall body can be an upper floor slab and a lower floor slab, so that in practical application, the bottom of the initial cavity wall body is required to be cut for a second set distance, and the reason is consistent with the above, and in order to facilitate the connection of the obtained target cavity wall body with the floor slab in the building, if the bottom of the initial cavity wall body is not cut, the installation of the target cavity wall body and the floor slab in the building may be inconvenient, and in practical application, after the installation of the target member and the target cavity wall body is completed, the cut part of the initial cavity wall body is filled.

In practical applications, the second set distance may be 50 mm.
In this embodiment, the bottom of the initial cavity wall body is cut by the second set distance, so that the initial cavity wall body is better connected with the upper floor slab and the lower floor slab in the building.
