In one aspect of the present invention, as shown in fig. 1, there is provided a building construction simulation method based on BIM data, including:
step S101, a BIM three-dimensional model of the building is obtained.
In this step, a BIM three-dimensional model of the building is obtained. The BIM three-dimensional model comprises a building structure model and a comprehensive pipeline model. And marking the position of the easy-to-collide pipeline in the BIM three-dimensional model. The building structure model based on BIM data comprises a building main body graphic element, wherein the main body graphic element comprises three-dimensional geometric bodies of building outer walls and inner walls representing building structures, main bodies and building, and corresponding building component bodies comprise wall components and design information such as wall construction layers, thickness, height and the like in the building model.
And step S102, marking the position of the pipeline which is easy to collide on the constructed pipeline.
In this step, in the building structure model, a constructed pipeline model is generated according to the constructed pipeline data collected on site as shown in fig. 5, and the constructed pipeline monitoring area is marked at the position, such as the position a in fig. 6, of the easy-to-collide pipeline corresponding to the constructed pipeline model. The construction pipeline model comprises the following components: water supply and drainage pipelines, heating pipelines, electric power pipelines, gas pipelines and other engineering pipelines.
The "collision line position" refers to a position where the line is easily crossed and collided due to an actual construction structure or space limitation during the line wiring process. The marked constructed pipeline monitoring area is a range area taking the position of the easy-to-collide pipeline in the construction pipeline model as the center.
Therefore, on the image of the pipeline of the constructed pipeline model, the constructed pipeline monitoring area is marked by adding a marking mark or a frame color.
And step S103, judging the collision of the constructed pipeline and the pipeline to be constructed.
In the step, according to absolute position data of a pipeline to be constructed in the comprehensive pipeline model, a simulated pipeline to be constructed is generated in a constructed pipeline monitoring area. After the generation, judging whether the to-be-constructed simulation pipeline collides with the constructed pipeline, and if so, adjusting the position of the to-be-constructed simulation pipeline.
The absolute position data of the pipeline to be constructed in the comprehensive pipeline model refers to that after the constructed pipeline model is generated, the pipeline model of the constructed pipeline is removed from the initial design, the mark point of the building is used as an alignment point, or the set position of the pipeline is used as an alignment point, and the three-dimensional model of the pipeline to be constructed is generated in a constructed pipeline monitoring area, so that the simulated pipeline to be constructed is simulated and generated in the constructed pipeline monitoring area.
In the constructed pipeline monitoring area, judging whether the to-be-constructed simulation pipeline collides with the constructed pipeline, namely, whether the to-be-constructed simulation pipeline has a cross on a geometric body or not, and if the to-be-constructed simulation pipeline has the cross, adjusting the pipeline position in the to-be-constructed simulation pipeline.
Therefore, according to the building construction simulation method based on BIM data, through acquisition of on-site constructed pipeline information, only models of constructed pipelines and pipelines to be constructed are generated in an easy-collision area, and the problem that the BIM model is large in data quantity and cannot be used smoothly when being loaded integrally is solved.
Meanwhile, the problem that the pipeline design loses the referential property due to the change of the pipeline position when the management construction position is changed due to the change of the site construction structure can be effectively solved.
In one embodiment of the building construction simulation method based on BIM data of the present invention, the building is a multi-story building.
The building construction simulation method based on BIM data comprises the following steps:
and sequentially reading the single-layer BIM three-dimensional model according to the construction sequence of floors. Thereby further reducing the amount of data loaded at a single time. The utilization rate of the data is improved, and the calculation speed of the data is increased.
And obtaining the trajectory of the comprehensive pipeline model in the single-layer BIM three-dimensional model. According to the section boundary of the pipeline, a plurality of section boundary lines are sequentially generated around the track line of the section boundary. Thus, a single load of data is reduced, and a display speed is increased.
The easy-to-collide pipeline positions comprise a high-density pipeline position, a narrow space position and a variable space position. Thus, a single load of data is reduced, and a display speed is increased. The high-density pipeline position means that the average pipeline spacing in the area is smaller than the designed pipeline average spacing.
And obtaining the density value of each section of pipeline in the single-layer comprehensive pipeline model. High density pipeline locations are marked in each section of pipeline that are greater than a pipeline density threshold or average pipeline density. A high density pipeline position tag is formed on the trace line of the pipeline. Thus, a single load of data is reduced, and a display speed is increased.
And acquiring a narrow space position in the building structure model. And marking a narrow space position on a pipeline of the comprehensive pipeline model, and forming a high-density pipeline position label on a track line of the pipeline. Thus, a single load of data is reduced, and a display speed is increased.
And acquiring the change space position in the building structure model. Marking the changing space position on the pipeline of the comprehensive pipeline model, and forming a space changing pipeline position label on the track line of the pipeline. Thus, a single load of data is reduced, and a display speed is increased.
As shown in fig. 4, in another embodiment of the building construction simulation method based on BIM data of the present invention, it includes:
the constructed line monitoring area is marked by a three-dimensional wire frame box 10. The length extension direction of the three-dimensional wire frame box coincides with the extension direction of the pipes 21, 22 and 23 in the constructed pipe model. And selecting a corresponding part of building structure model by using the three-dimensional wire frame box frame.
In still another embodiment of the building construction simulation method based on BIM data of the present invention, the method includes:
as shown in fig. 4, according to the construction order of the respective pipes to be constructed, the simulated pipes to be constructed 21, 22, 23 and 31, 32 are sequentially generated in the three-dimensional wire frame box 10 according to the absolute position data of the pipes to be constructed.
The projected location and boundaries of the constructed pipe cross section on the exterior face of the three-dimensional wireframe box 10 are generated.
And after the simulated pipeline to be constructed, generating the projection position and the boundary of the cross section of the simulated pipeline to be constructed on the outer surface of the three-dimensional wire frame box.
As shown in fig. 4, whether the constructed line and the simulated line are intersected is judged according to the position and boundary of the constructed line generated on the outer surface of the three-dimensional wire frame box and the position and boundary of the simulated line to be constructed generated on the outer surface of the three-dimensional wire frame box, for example, the intersection boundary of the simulated lines to be constructed 21, 22, 23 and 31, 32 and the outer surface of the three-dimensional wire frame box 10, the intersection state is in the figure, if not, the volume of the three-dimensional wire frame box is reduced by 1/2 or 1/3, the projection position and boundary of the cross section of the constructed line on the outer surface of the three-dimensional wire frame box are generated again, and the projection position and boundary of the simulated line to be constructed on the outer surface of the three-dimensional wire frame box are generated again, and whether the intersection state is judged again. Therefore, the condition that the internal pipeline is bent in multiple directions is avoided, and if yes, collision information of the simulated pipeline to be constructed and the constructed pipeline is output. Thereby judging whether the constructed pipeline and the pipeline to be constructed are crossed or not.
In still another embodiment of the building construction simulation method based on BIM data of the present invention, the method includes: if the collision information is output as the collision information of the simulated pipeline to be constructed and the constructed pipeline, the simulated pipeline to be constructed and the constructed pipeline which collide are aligned through an ICP algorithm or an FGM algorithm, if the collision information cannot be aligned, the collision information is output, and if the collision information cannot be aligned, the pipeline layout error information is output.
Because the sections of various pipelines are generally different, the repeated wiring of the pipelines of the same type can rarely occur in the same wiring direction, and meanwhile, if the repeated wiring is performed, the repeated wiring of the pipelines of the same shape can rarely occur, so that the design errors generated in the process of designing the pipelines can be effectively detected in an alignment mode.

The simulated pipeline to be constructed comprises a ventilation pipeline or a fuel gas pipeline.
