Description
Technical Field
The invention relates to the technical field of building design, in particular to a method for generating a residential basement fireproof partition minimum area unit based on BIM.
Background
Concept of fire partition in building: the fireproof partition is a region partitioned by a firewall, a floor slab, a fireproof door or a fireproof roller shutter, the fire can be limited in a certain local region, the fire is not spread in a certain time, and meanwhile, the partition of the fireproof partition also plays a partition role on smoke.
The area of the fireproof partition is defined by:
in building design fire codes GB 50016-2014 (2018 edition), there are certain restrictions and requirements regarding the area of each fire-resistant zone. For example, the fireproof partition of a motor vehicle garage of a basement is 2000 square meters, and when an automatic spraying alarm system is arranged in the partition, the area of the partition can be doubled, namely 4000 square meters.
Compared with the traditional graph for randomly dividing the fireproof subareas in the brain design, the method has the advantages that the fireproof subareas are subjectively arranged only by CAD drawing software, and the polygonal area is manually consulted, so that the area of each fireproof subarea is balanced. The disadvantage of this method is that it is slow to operate manually, the lines of manual division are inaccurate, and the area of each fire zone cannot be known immediately, and the design efficiency is low.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a generating method of a residential basement fireproof partition minimum area unit based on BIM, which can quickly combine and generate the area unit, thereby improving the design efficiency, reducing the manual intervention and improving the design accuracy.

editing information of the family members in a Revit platform according to requirements;
converting the family member into an area unit and a fire protection unit;
combining the area units according to the number of the fireproof subareas of the civil engineering model to form each fireproof subarea, and immediately adjusting the area and the boundary of the fireproof subarea by adjusting the number of the area units so as to divide the fireproof subareas;
wherein the step of converting the family member into the area unit further comprises:
s01, searching room families of independent areas in Revit, wherein the functional space mainly comprises a basement ash space and a fire water pool;
s02, searching a room boundary with the same keyword name in a device room and an affiliated room family thereof in a Revit, expanding the boundary into a wall, and generating an area line by using a central line of a wall body of the room;
s03, searching a core tube filling area family of a residential tower area in a Revit, checking whether the shape of the core tube coincides with the wall body of a core tube room, checking whether the number of the core tube filling areas is repeated or lost, adjusting the boundary of the filling area family to coincide with the wall body of the core tube, and generating an area line by using the central line of the wall body of the room;
s04, searching a boundary of a single parking space family in the Revit, and generating an area family by shifting the boundary according to a certain rule;
s05, searching a filling area family of an end user or a wing user of the residential tower area in the Revit, deducting the area family generated in the steps S01-S04 to generate corresponding area side lines, expanding the boundary into a wall, and generating the area lines by using the central line of the wall body of the room;
when the distance between the basement boundary area line and the end wing households is smaller than 100mm, the basement boundary area line is the end wing households;
s06, searching a non-motorized garage and an accessory space thereof in the Revit, searching a room boundary with the same keyword name, expanding the boundary into a wall, and generating an area line by using a central line of a wall body of the room;
s07, searching an automobile ramp in a Revit, searching a boundary of a room, expanding the boundary into a wall, and generating an area line by using a central line of a wall body of the room;
