Problems solved by technology

[0002] When the traditional construction industry builds some large buildings such as hospitals, it needs to install more equipment such as water supply, HVAC, electrical, fire-fighting and other pipelines, as well as various civil engineering and electromechanical equipment installations, and in inpatient buildings, medical technology buildings, The main structure such as the outpatient building is gradually being completed, and when equipment needs to be installed, it is discovered that due to the small space in the basement, there are various comprehensive pipelines in the hospital, which makes the construction difficult
[0003] In addition, during the construction process, the drawings need to be replaced at any time according to the actual size of the site. For the existing CAD drawing method, a small data change may replace many drawings, which brings great inconvenience to the construction unit. At the same time, the construction period was delayed; the construction distance, maintenance space, and net height of various pipelines and equipment must meet the requirements of on-site construction. There is no preset model in the existing technology, which can only be solved in time when encountering situations, and cannot solve such problems Avoidance prevention, so there is an urgent need for a house construction method that can preset models and improve installation quality

Embodiment 1

[0019] Example 1: See figure 1 , a method for building a house based on a BIM preset model in this embodiment includes the following steps: S1: Establish a civil engineering BIM model of the housing, and build the overall structure according to the civil engineering BIM model of the housing; The error is controlled within the tolerance range; the actual structural size whose structural error is not within the tolerance range is imported into the building civil engineering BIM model in S1; S3: review and correct the housing civil engineering BIM model according to the actual structural size; S4: establish the mechanical and electrical BIM separately model, and conduct a separate inspection of the BIM electromechanical model; the electromechanical model includes the pipeline model and the equipment model; S5: Integrate the electromechanical BIM model and the building civil BIM model in S3, and conduct collision inspection; S6: If there is a collision point, according to the colli...

Embodiment 2

[0020] Embodiment 2: This embodiment also includes identifying and distinguishing civil engineering BIM models and electromechanical BIM models according to component families to form a filter system. It is convenient for others to understand the drawings and reduces the difficulty of processing technology. In step S5 of this embodiment, the distance between the strong current bridge and the weak current bridge frame is not less than 0.3m, and the distance between the pipelines is not less than 0.1m. In this embodiment, before step S8, it also includes establishing a BIM model of the support and hanger, and pre-installing the support and hanger before installing the pipeline, and the support and hanger is used to fix the pipeline to the beam. It can optimize the pipeline layout route, calculate the optimal support and hanger arrangement in advance, and make arrangements in advance at the positions where support and hangers need to be installed. In this embodiment, the load-be...

Embodiment 3

[0021]Embodiment 3: The drawing colors of various pipes in this embodiment are different, and different pipes are distinguished by color. In the actual construction process, a color printer is also required to print construction drawings, which is convenient for construction personnel to carry out accurate construction. In step S8 of this embodiment, the installation position of the pipeline in the BIM model is corrected according to the actual construction situation, and the correction interval is ±5cm. Since the on-site construction cannot be exactly the same as the geometric dimensions given in the drawings, after construction, it is necessary to re-measure and import the actual dimensions into the BIM model for collision detection again. In this embodiment, in step S4, in the process of establishing the pipeline model, spaces for turning and tees are reserved for the pipeline branch pipes. The pipeline layout is intricate. According to the BIM model, you can know in advan...
