Description

Background

In the process of developing a real estate, the general diagram design is very influenced by the localization rule as an important working link. For example, there is a clear requirement for the sunshine interval between buildings in local regulations, and the hard requirement of the regulations is a reference condition which must be met in the overall diagram arrangement process. Therefore, when a designer plans a residential area, the building needs to be positioned and arranged. In the arrangement process, the sunshine space, the gable space and the fireproof space among the buildings need to be checked in real time, and the design scheme is established only if the spaces meet the national and regional specifications.

The conventional general diagram arrangement does not have any similar auxiliary function, and designers need to manually place buildings in the field according to the understanding and experience of national and regional specifications, calculate the positions of the buildings constantly and check whether the specifications are met. If the standard is not met, the scheme needs to be modified. The method has high operation repeatability and is easy to make mistakes. In addition, because of the wide difference in experience between designers, learning regional specifications requires a certain time and cost for a design team across regions or a designer with a shallow resource, and the designer may not necessarily have the knowledge in the part. Furthermore, when a designer manually draws the sunshine or fire-fighting auxiliary lines on the building according to the standard requirements, the designer needs to master different building types and products to draw different line types besides requiring to master the standard skillfully, the work is complicated, the consumed time is long, and mistakes are easy to make.

In view of the above, there is a need in the art to develop a new method and apparatus for processing architectural drawings.

It is to be noted that the information disclosed in the above background section is only for enhancement of understanding of the background of the present disclosure, and thus may include information that does not constitute prior art known to those of ordinary skill in the art.

Furthermore, various building auxiliary lines are drawn based on the initial building outline or the target building outline, an automatic and intelligent drawing mode of the building auxiliary lines is provided, the drawing effects of regular datamation and visualization are achieved, the drawing precision and the drawing efficiency of the building auxiliary lines are improved, and the learning cost and the using cost caused by drawing of the building auxiliary lines are reduced. Furthermore, the adjustable interface can be correspondingly arranged in order to adapt to different regional rules, so that the flexibility and the practicability are high, and the application scene of drawing the building auxiliary line is enriched.

The following describes each step of the processing method of the construction drawing in detail.

In step S110, an initial building outline in the building drawing and building specification data corresponding to the building drawing are obtained, and a target building outline is generated according to the initial building outline.

In an exemplary embodiment of the present disclosure, the building drawing may be a drawing of a building in a residential area, or may be a drawing of other buildings, and this exemplary embodiment is not particularly limited thereto.

The residential area planning may be a specific arrangement in which the layout structure of the residential area, the arrangement of residential groups, road traffic, life service facilities, various green and recreational areas, municipal utilities, and various systems of municipal pipe networks, etc. are integrated.

Accordingly, the initial building outline may be a top view of a building in a residential area, or a top view of other buildings, or other views, etc., which the exemplary embodiment is not particularly limited to.

In an alternative embodiment, the building code data includes: gable standard data, sunshine standard data and fire standard data.

Wherein, the sunshine interval is between two rows of south houses in the front and back, minimum spacing distance for guaranteeing that the house accords with the regulation and keeps.

As shown in table 1, table 1 shows sunshine specification data corresponding to sunshine intervals:

TABLE 1

The gable wall is commonly called as an outer transverse wall. The walls arranged along the minor axis of the building are transverse walls, which are generally called gable walls. The function of the gable is mainly to separate and prevent fire from the neighboring houses.

Correspondingly, the gable spacing is the distance between the gable walls of two adjacent buildings, and the distance needs to meet the design specification of each city, namely the gable specification data.

As shown in table 2, table 2 shows the gable specification data corresponding to the gable spacing:

TABLE 2

The fire prevention interval is the minimum distance that a building can be on fire, and the opposite building can not be on fire under the action of heat radiation even if no protective measures are taken.

As shown in table 3, fig. 3 shows fire code data corresponding to fire intervals:

TABLE 3

Further, a corresponding target building outline may be generated from the initial building outline.

Specifically, the maximum lateral spacing of the initial building profile in the horizontal direction is obtained, and the maximum longitudinal spacing of the initial building profile in the vertical direction is obtained. And generating a minimum rectangular frame containing the building by using the maximum transverse spacing and the maximum longitudinal spacing as a target building outline. The target building profile may be an enclosure box.

In step S120, a building attribute is calculated according to the building drawing, and the building attribute and the building specification data are matched to obtain contour line data.

In an exemplary embodiment of the present disclosure, calculating data representative of a construction drawing enables obtaining a construction attribute.

In an alternative embodiment, the architectural attributes include: a height attribute, a first scale, and a second scale.

Wherein the determination of the height attribute may be achieved by a corresponding height threshold.

In an alternative embodiment, the height attribute includes high levels and multiple levels, and FIG. 2 shows a flow diagram of a method of calculating building attributes, as shown in FIG. 2, the method including at least the steps of: in step S210, a height threshold corresponding to the height attribute is obtained, and a building height represented by a building drawing is obtained.

The height threshold may be 24m, or may be other values, which is not particularly limited in this exemplary embodiment.

In step S220, if the building height is less than or equal to the height threshold, the height attribute is determined to be multi-story.

After the building height and the height threshold are obtained, the building height may be compared with the height threshold to obtain a comparison result.

And when the comparison result shows that the building height is less than or equal to the height threshold value, the building on the building drawing is a multi-storey building.

In step S230, if the building height is greater than the height threshold, the height attribute is determined to be a high level.

And when the comparison result shows that the building height is greater than the height threshold value, the building on the building drawing is a high-rise building.

In the exemplary embodiment, the height attribute can be determined through the comparison result of the building height and the height threshold, the determination mode is simple and accurate, the determination mode is closely attached to the actual life, and the practicability is extremely high.

In an alternative embodiment, fig. 3 shows a flow chart of another method for calculating building attributes, which, as shown in fig. 3, at least comprises the following steps: in step S310, the building height, the building width, the building depth, and the building face width represented by the building drawing are obtained, and the building height and the building width are calculated to obtain a first ratio.

The face width can be the house face width and represents the whole width of a house lighting face; the depth may be a house depth, which represents the overall width of the house lighting surface in the direction of extension into the room.

Specifically, the building height and the building width may be calculated by dividing the building height and the building width to obtain an aspect ratio, and determining the aspect ratio as the first ratio.

In step S320, the building depth and the building width are calculated to obtain a second ratio.

Specifically, the building depth and the building face width may be calculated by dividing the building depth and the building face width to obtain a depth-height ratio, and determining the depth-height ratio as the second ratio.

In the exemplary embodiment, the first proportion and the second proportion can be correspondingly calculated through the building height, the building width, the building depth and the building surface width, so that the diversity of building attributes is increased, and a data base and theoretical support are provided for the subsequent drawing of the building auxiliary line.

After the building attributes are calculated, the building attributes can be matched with the building specification data to obtain contour line data.

For example, when the high-rise attribute is high and outside of three rings, and the aspect ratio ≦ 1.2 and the building height >24m, the height spacing coefficient may be determined to be 2.0 in the sunshine specification data shown in Table 1. Therefore, the contour line data is 2.0 × the building height, or the height pitch coefficient is directly used as the contour line data, which is not particularly limited in the present exemplary embodiment.

When the height attribute is a high-rise building, the height attribute can be matched with the gable specification data shown in the table 2 to determine the distance line between the gable of the multi-story high-rise building, and the contour line data is 13 m; when the high-rise main road is approached, the contour line data is 30 m.

When the height attribute is high-rise, the contour line data can be determined to be 6m when the building is a skirt house or a non-high-rise civil building; when the building is a high-rise civil building, the contour line data is 9 m.

It should be noted that since the type of the building or information other than the building attribute cannot be determined from the construction drawing, all contour line data satisfying a known specification can be determined from the construction specification data to draw a plurality of construction assistance lines in various cases.

In step S130, a building auxiliary line is drawn in the construction drawing from the contour line data based on the initial building contour or the target building contour.

In an exemplary embodiment of the present disclosure, after the contour line data is determined, a building auxiliary line may be drawn in the building drawing based on the contour line data.

In an alternative embodiment, the building aid line comprises: gable interval auxiliary line, sunshine interval auxiliary line and fire prevention interval auxiliary line.

The gable building auxiliary line is the contour line of a gable of one building which can influence the gable of other buildings. If other buildings are not in the outline, the other buildings do not conflict with the local building in the distance between the gable walls. The spacing building auxiliary line can comprise a multi/multi-gable line, namely a multi-storey receding multi-storey building gable spacing line; the multi/high mountain wall line is the mountain wall spacing line of the multi-storey high-rise building.

The auxiliary line of the sunshine space is a contour line of one building which can influence the sunshine of other buildings. If other buildings are not in the outline, the other buildings conflict with the local building in sunlight space.

Specifically, the solar radiation interval auxiliary line may include a multi-layer solar radiation line, that is, a multi-layer building solar radiation interval auxiliary line; high-rise sunshine line, namely high-rise building sunshine interval auxiliary line.

The fire-proof interval auxiliary line is a contour line of a building which can influence the fire resistance of other buildings. If the other buildings are not in the outline, the other buildings do not conflict with the local building in fire-proof distance. The fire-proof space auxiliary line is an auxiliary line for withdrawing the fire-proof requirement of the building.

In an alternative embodiment, fig. 4 shows a flow diagram of a method for drawing a building auxiliary line, which, as shown in fig. 4, at least comprises the following steps: in step S410, a gable interval auxiliary line and a solar radiation interval auxiliary line are drawn in the construction drawing from the contour line data based on the target building contour.

When drawing the gable spacing auxiliary lines, the gable spacing auxiliary lines are drawn to the left and right sides with the short side of the target building outline as a reference.

When drawing the sunshine spacing auxiliary line, drawing the sunshine spacing auxiliary line to the north side with the long side of the target building outline as a reference.

In step S420, a fire prevention interval auxiliary line is drawn in the construction drawing according to the contour line data based on the initial construction contour.

Before drawing the fire-proof space auxiliary line, the initial building outline can be subjected to de-weighting treatment.

In an alternative embodiment, fig. 5 shows a flow diagram of a method for performing a de-duplication process on an initial building outline, as shown in fig. 5, the method comprising at least the following steps: in step S510, contour points of the initial building contour are acquired, and the intervals between the contour points are calculated.

Traversing the points that make up the initial building outline can result in a number of outline points, for example 6. Further, the distance between every two contour points is calculated from the 2 nd contour point of the 6 contour points.

In step S520, if the distance is smaller than or equal to the corresponding distance threshold, the contour points corresponding to the distance are removed to obtain the initial building contour after the duplication removal.

After the pitch between the contour points is calculated, a pitch threshold corresponding to the pitch may be acquired. In general, the distance threshold may be 0 or other values, which is not limited in this exemplary embodiment.

When the distance between the 2 nd contour point and the 3 rd contour point is equal to 0, the 2 nd contour point and the 3 rd contour point are indicated to be repeated points obtained by non-compliant drawing, and therefore one of the 2 nd contour point and the 3 rd contour point can be removed to obtain the initial building contour after the weight is removed.

In the exemplary embodiment, the duplication elimination of the initial building outline can be realized by calculating the distance between the outline points, the problem of repeated points in the drawing process is solved, and the problem of inaccurate drawing of the auxiliary lines caused by inaccurate initial building outline is avoided.

In an alternative embodiment, fig. 6 shows a flow chart of a method for drawing a fire-retardant spacing auxiliary line, and as shown in fig. 6, the method at least includes the following steps: in step S610, an initial fire prevention auxiliary line is generated by shifting from the contour line data based on the initial building contour.

And when the contour line data is 6m, outwards expanding each line of the initial building contour by 6m, drawing a circle by taking the intersection point of the expanded lines as the center of the circle and 6m as the radius, and connecting the intersected arcs to form an initial fire-proof auxiliary line.

In step S620, the initial fire prevention auxiliary line is cut by using the sunshine interval auxiliary line to obtain a fire prevention interval auxiliary line in the architectural drawing.

When the fire-prevention space auxiliary line is generated according to the initial fire-prevention auxiliary line, it is determined that the sunshine space auxiliary line has been drawn.

Therefore, the overlapping portion of the initial fire-retardant auxiliary line and the northern sunshine interval auxiliary line is cut, and the cut portion is left to obtain the fire-retardant interval auxiliary line.

In the exemplary embodiment, the auxiliary line of the fire prevention space is generated by using the auxiliary line of the sunshine space and the contour line data, the generation mode has strong flexibility, and the accuracy is extremely high.

And generating a minimum rectangular frame containing the building by using the maximum transverse spacing and the maximum longitudinal spacing as a target building outline. The target building profile may be an enclosure.
