Embodiments of the present invention are further elaborated below in conjunction with accompanying drawing 1:

The pipeline layout method of prefabricated steel structure building includes the following steps:

S1: Obtain the building structure diagram and the pipeline direction profile.

It should be understood that the building structure drawing and the pipeline sectional drawing are based on the two-dimensional plan design drawing obtained after the construction site measurement.

S2: Obtain the initial 3D model diagram corresponding to the building structure diagram and the pipeline direction section diagram.

It should be understood that the initial 3D model diagram can be obtained by importing the 2D plane design diagram in S1 into the 3D software for modeling.

It should be understood that the sectional view of the pipeline refers to the sectional view of the pipeline routing pipeline. According to the sectional view of the pipeline direction, the specific direction of the pipeline in the building and the position of the wire slot can be restored.

S3: In the initial 3D model drawing, obtain the areas in the steel beam and/or the base wall where the pipeline routing needs to be optimized.

It should be understood that, in some embodiments, the optimized area refers to the pipeline routing area of the base wall itself; in other embodiments, it may also be the area adjacent to the base wall and the steel beam.

S4: In the selected area, adjust and optimize the pipeline arrangement and/or the position of the foundation wall according to the optimization rule.

It should be understood that the setting of the optimization rule can be set according to the structural characteristics of the wall and the steel beam itself, so as to avoid the damage to the wall structure and the steel beam structure caused by the pipeline arrangement.

It should be understood that the optimization rules can also be set according to the construction requirements of the building and building materials. For example, the regularity of the pipeline routing will affect the later maintenance; therefore, the pipeline routing can be arranged in an orderly manner according to the optimization rules, thereby improving the quality of the building and avoiding the difficulty of later maintenance and the damage to the wires when installing hardware.

Therefore, according to the characteristics of the building structure, an optimization rule matching this building can be set.

S5: According to the optimized 3D model drawing, output the construction drawings.

Through the above three-dimensional modeling method, the building information is displayed more intuitively, and the system design is optimized according to the pipeline routing rules set based on the characteristics of the building structure. At this time, the construction according to the optimized drawings can avoid the phenomenon of rework caused by unreasonable wiring, so as to improve the efficiency and quality of the building.

In some embodiments, the optimization rule further includes: only one side of the base wall is provided with pipelines. By arranging pipelines only on one side of the wall, it is possible to avoid the situation that the wall is slotted on both sides, thereby affecting the stability of the wall.

It should be understood that the grooves on both sides of the wall, if the construction is not standardized, lead to the groove being too deep, which will destroy the stability of the wall. When used for a certain number of years, the wall is easy to crack or collapse.

In some embodiments, the optimization rule includes that the position of the base wall protrudes outward relative to the position of the steel beam, the pipeline is perpendicular to the ground, and extends upward through the base wall to the outside of the steel beam. The pipeline can be fixed on one side of the steel beam perpendicular to the ground without the need for grooves in the steel beam structure. It not only satisfies the vertical upward arrangement of pipelines, but also ensures the safety of the building.

It should be understood that, for buildings with a steel beam structure, it is necessary to avoid grooving on the steel beams, so as not to affect the bearing capacity of the steel beams. Therefore, when the line is perpendicular to the ground and upwards, the base wall needs to protrude from the position of the steel beam, so that when the line pipe of the pipeline extends through the base wall to the side of the steel beam, it can be fixed on the side of the steel beam. , thereby maintaining the complete structure of the steel beam.

It should be understood that the lateral slotting will affect the bearing capacity of the wall, especially the load-bearing wall, so the lateral slotting should be avoided as much as possible for pipeline wiring. At the same time, the way of running the line perpendicular to the ground and upward can quickly determine the position of the line pipe, so as to improve the efficiency of construction. Therefore, the optimization rules should be perpendicular to the ground and run upwards as much as possible, which can simplify the construction and ensure the safety of the building at the same time.

It should be understood that, in some embodiments, the optimization of pipeline routing includes not only arranging pipelines on one side of the wall body, but also a manner in which the pipelines are perpendicular to the ground and run upwards, so as to meet the safety and maintenance requirements of the building. In other embodiments, the optimization of the pipeline routing only includes arranging pipelines on one side of the wall or the pipelines are perpendicular to the ground and run upwards.

In some embodiments, the location of the base wall protrudes outward by a distance of 10-20 mm. When the outwardly protruding distance is set to 10-20mm, when the pipeline is perpendicular to the ground and runs upwards, the base wall will not protrude too much from the steel beam, thus affecting the overall appearance.

In some embodiments, the method for routing the pipelines of the fabricated steel structure building further includes the following steps: performing on-site construction according to the construction drawings. By strictly following the designed drawings, the efficiency of the building can be improved.

It should be understood that, since the on-site construction has been displayed in a three-dimensional mode and systematically optimized in the early stage of the design, when the construction is carried out strictly in accordance with the drawings in the later stage, an effective division of labor can be carried out, and the accurate and efficient implementation can be carried out to improve efficiency.

In some embodiments, the on-site construction according to the construction drawings further includes the following steps:

Slot the conduit in the base wall according to the construction drawings.

Fill the steel beams and level them with plastering.

By filling, plastering and leveling the steel beam after the line pipe is arranged, the line pipe can be fixed on one side of the steel beam, and the wall and the steel beam as a whole are more flat and beautiful.

It should be understood that, according to the construction drawings and the diameter of the pipeline, a slot can be made at the corresponding position of the pipeline in the construction drawing, and the electric wire can be placed in the pipeline and placed in the slot. Since the base wall is more protruding than the steel beam, the pipeline with the wires is only on one side of the steel beam. The pipeline can be further secured to the steel beam by applying mortar leveling to the steel beam. At this time, the surface of the wall and the steel beam is flush on one side, and the overall building is more beautiful; while the wall on the other side is slightly recessed inward, which can be covered by simple wall decoration in the later stage.

In some embodiments, the base wall includes ALC slats. Building the base wall through ALC can improve the efficiency of the building.

It should be understood that ALC slats can be sawed, cut, planed, drilled and dried, thus improving construction efficiency.

It should be understood that, in some embodiments, the walls of the base wall may employ only ALC battens. In other embodiments, the wall also includes a cement-filled wall and a wall composed of ALC slats.

In some embodiments, the optimized three-dimensional model diagram is obtained by BIM software. Through BIM, the process of pipeline routing optimization in 3D building models can be simplified.

It should be understood that BIM can automatically detect problems in drawings, coordinate collision problems and generate data, such as duct and beam collisions; thus simplifying the optimization workload to improve work efficiency.

It should be understood that the use of BIM can also synchronize the drawings with the model, and can also connect with the later construction unit to simulate the time and cost of the construction period. If there are errors, it can be revised in time to achieve the purpose of supervision and management.

Specifically, with reference to FIG. 1 , the construction process of a method for arranging pipelines in a prefabricated steel structure building according to the present invention will be described in detail with a specific embodiment. It is to be understood that the following description is illustrative only and not specific limitation of the invention.

Specifically, before construction, the building is measured first, and a plan design drawing such as the building structure drawing and the pipeline routing section drawing in S1 is obtained. Next, as shown in Figure 1, the graphic design drawings are imported into the BIM software, and the initial 3D model diagram corresponding to the building structure diagram and the pipeline profile in S2 can be obtained.

At this point, in the initial 3D model, you can intuitively see the routing positions of pipelines on ALC walls, infill walls, and steel beams.

It should be understood that, due to the need for grooving when arranging the pipeline, the structure of the wall and the steel beam will be affected, thereby affecting the safety of the building. Therefore, systematic pipeline routing optimization is required for walls and steel beams. Considering that the wall has double-sided wiring, and the double-sided wiring needs to be slotted on both sides of the wall during actual construction. At this time, if the groove depth is too deep, it is easy to cause the wall structure to be unstable and collapse in the later stage. Therefore, the wall is first optimized.

At this time, go to step S3, and select the wall area in the BIM, wherein the wall includes the infill wall and the ALC wall.

Next, step S4 is entered to optimize and adjust the selected wall area. The optimization rules are as follows:

Rule 1: Adjust the double-sided wiring of the wall to one-sided.

when optimization is complete. Repeat steps S3 and S4 to enter the next optimization. In this embodiment, since some of the walls are ALC walls, the ALC walls are easily structurally unstable due to the fact that the ALC walls have multiple transverse grooves. Therefore, the optimization area of the wall and steel beam is selected for optimization. At this time, the second rule is carried out for the ALC wall to avoid horizontal grooving of the wall. The optimization rules are as follows:

Arrange the pipelines vertically in the wall and upwards.

At the same time, considering that the steel beam of the building's structure is I-beam. However, only if the pipelines on the ALC wall are perpendicular to the ground and run upwards, the steel beams need to be slotted to penetrate the steel beams. In this embodiment, I-shaped steel beams are used. When the I-shaped steel beams are slotted, especially It is the part of the beam and wing, which will affect the force of the I-beam, thereby affecting the safety of the building.

Therefore, the optimization rule also includes adjusting the wall position of the ALC so that it protrudes from the I-beam.

Secondly, considering the beauty of the building and the thickness of the pipeline, the protruding distance is selected to be between 10-20mm.

At this point, the pipeline is perpendicular to the ground and goes up through the ALC wall against the side of the steel beam.

For the infill wall, since the horizontal wiring is easy to damage the pipeline when installing the hardware later, the optimization rules for ALC walls and steel beams are also applicable to the infill wall. At this time, according to the optimization method in Rule 2, the infill wall is optimized.

At this time, according to Rule 1 and Rule 2, the systematic optimization of the pipeline is completed to obtain an optimized three-dimensional model, and at this time, step S5 can be entered to output the corresponding construction drawings. After obtaining the output drawings, on-site construction can be carried out according to the output construction drawings.

During construction, workers constructed steel beams and walls in strict accordance with the output drawings. When the steel beam is constructed, according to the drawings, the side of the ALC wall is perpendicular to the ground and grooved upward, and the line pipe is installed. At this time, the line pipe is close to the side of the steel beam. After all the pipelines are arranged in the line pipe, the steel beams are filled with beam pockets, and plastered and leveled, so that the steel beams are flush with one side of the wall.

Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, The scope of the invention is defined by the claims and their equivalents.

The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned embodiments, and can also be made within the scope of knowledge possessed by those of ordinary skill in the technical field without departing from the purpose of the present invention.
