[0035] like Figure 1 As shown, a method for determining the thickness of a slope layer based on BIM in an embodiment of the present invention includes the following steps:

[0037] S2. Based on the position information and height information corresponding to all the exhaust ducts, the thickness of the slope layer corresponding to each room of the independent household is determined, and a three-dimensional display is performed.

[0038] The beneficial effects of the BIM-based slope layer thickness determination method provided by the present invention are as follows:

[0039] By generating a BIM three-dimensional diagram containing all exhaust ducts based on the slope layer thickness determination request, and combining the location and height information of the exhaust ducts to determine the slope layer thickness of each room for three-dimensional display, the accuracy of design and construction can be improved and errors can be reduced; at the same time, the design and construction efficiency can be improved, time can be saved and the construction process can be optimized; information sharing and collaboration can be enhanced, and efficient communication and collaboration between all parties can be promoted in the same model; project costs can be reduced, material waste can be reduced and construction period can be shortened; in addition, the visualization effect can be improved, and the internal structure and construction details of the building can be intuitively displayed to facilitate communication and decision-making.

[0040] Slope thickness refers to the thickness of the concrete layer installed during ground or roof construction to create a specific drainage slope. Its primary function is to ensure smooth drainage of the ground or roof, preventing water accumulation from damaging the structure while also improving its stability and service life.

[0041] In S2, based on the location information and height information corresponding to all the exhaust ducts, the specific process of determining the thickness of the slope layer corresponding to each room of the independent household is as follows:

[0042] Determine the drain outlet location information of the building where the independent household is located (including the location of the external drainage pipe and the internal drainage pipe of the building) and the maximum drainage volume per minute, determine the annual precipitation corresponding to the geographical location of the building, determine whether the room to be calculated is a balcony, and when the room to be calculated is a balcony, determine whether there is a water supply pipe in the room. If not, determine the average water inflow per minute of the room based on the historical wind direction and wind speed mode in the area, determine the first drainage volume difference based on the maximum drainage volume per minute and the average water inflow per minute, and determine the slope of the slope layer based on the first drainage volume difference and the material of the slope layer.

[0043] If there is a water supply pipe, the water supply volume per minute of the water supply pipe is counted, and the water supply volume per minute is superimposed with the average water inflow per minute to determine the total water inflow per minute of the room. Based on the maximum drainage volume per minute and the total water inflow per minute, the second drainage volume difference is determined. According to the second drainage volume difference, the position of the water supply pipe and the material of the slope layer, the slope of the slope layer is determined.

[0044] The process of determining the slope of the slope finding layer according to the first drainage volume difference and the material of the slope finding layer is specifically as follows:

[0045] According to the material of the slope layer and the area of the room, the slope of the initial slope layer corresponding to the room without water supply pipe is determined by the preset model;

[0046] Searching a historical database for multiple historical slopes with similar modes of historical wind direction and wind speed corresponding to the building, determining the optimal slope among the multiple historical slopes, and determining the final slope corresponding to the room based on the optimal slope and the slope of the initial slope layer;

[0047] According to the final slope and the slope of the initial slope layer, the simulation slope range is determined. Through three-dimensional dynamic simulation software, based on the direction angle, wind speed mode, room area, room drain outlet location information, maximum drainage per minute, average water inflow per minute and simulation slope range, the simulation slope corresponding to the fastest drainage within the simulation slope range is calculated, and the simulation slope is determined as the construction slope of the room.

[0048] The specific process of searching for multiple historical slopes with similar historical wind directions and wind speed modes to the building is as follows:

[0049] Determine a direction angle based on the room's orientation and historical wind direction, determine an angle range based on the direction angle, determine a wind speed range based on the wind speed mode, search a historical database for all first historical slopes corresponding to the angle range, and search for multiple historical slopes within the wind speed range among all first historical slopes;

[0050] It should be noted that when the number of first historical slopes is less than three, the angle range is expanded by 10% and the search is performed again. When the number of first historical slopes is still less than three, the direction angle and the wind speed mode are calibrated. The direction angle, wind speed mode, room area, room drain position information, maximum drainage per minute and average water inflow per minute are simulated through three-dimensional dynamic simulation software. Different first slopes are tried during the simulation process, and the drainage speed corresponding to each first slope is calculated. The slope value with the fastest drainage speed and the lowest slope is selected in the preset slope range (2%-3%) and output as the final slope.

[0051] Among multiple historical slopes, the process of determining the optimal slope is the same as the method of determining the construction slope. Through three-dimensional dynamic simulation software, multiple historical slopes are simulated to determine the historical slope corresponding to the fastest drainage, which is the optimal slope.

[0052] The process of determining the slope of the slope layer according to the second drainage volume difference, the position of the water supply pipe, and the material of the slope layer is as follows:

[0053] Determine the target distance between the water supply pipe position and the drain outlet, and determine the target preset range corresponding to the target distance; determine the compensation value corresponding to the second drainage volume difference based on the coefficient corresponding to the target preset range, that is, determine the compensation value by multiplying the coefficient by the water supply volume per minute of the water supply pipe; remove the compensation value from the second drainage volume difference to obtain the third drainage volume difference; use the traced third drainage volume difference as the first drainage volume difference; and determine the "process of determining the slope of the slope layer according to the first drainage volume difference and the material of the slope layer" through the "process of determining the slope of the slope layer according to the first drainage volume difference and the material of the slope layer".

[0054] It should be further explained that the preset range is a pre-set proportional interval, namely the ratio of the distance between the water supply pipe and the drain outlet to the length or width of the room. For example, the first interval is: 0-30%, the coefficient is 0.15; the second interval is: 31-60%, the coefficient is 0.35; the third interval is: 61-100%, the coefficient is 0.65. If the room width is 3m and the distance between the drain outlet and the water supply pipe is 1m, the ratio is 1 / 3. For the second interval, the corresponding coefficient when calculating the compensation value is 0.35. The reason why this coefficient increases with increasing distance is that the closer the distance between the water supply pipe and the drain outlet is, the shorter the time and the greater the amount of water that flows into the drain outlet when the water supply pipe leaks or bursts. Therefore, when calculating the compensation value, the closer the distance, the lower the compensation value, and the farther the distance, the higher the compensation value.

[0055] Based on the slope of the slope layer and combined with the corresponding position information and height information of all exhaust pipes, the thickness of the slope layer at different locations is determined.

[0056] Furthermore, the construction process of the BIM three-dimensional diagram of the independent household is as follows:

[0057] Through the two-dimensional drawing of the independent household, the roof model and all exhaust ducts corresponding to the independent household were constructed in combination with Revit software;

[0058] Establish the roof layers and materials according to the selection instructions given by the user.

[0059] Furthermore, based on the position information and height information corresponding to all the exhaust ducts, the process of determining the thickness of the slope layer corresponding to each room of the independent household is specifically as follows:

[0060] Determine the target distance between the exhaust duct and the horizontal plane of each room, and by comparing the target distance of each room, determine whether the slope layer thickness of any room needs to be recalculated, and when the slope layer thickness of any room needs to be recalculated, calculate the slope layer thickness corresponding to the room.

[0061] Furthermore, it also includes:

[0062] Obtain the slope layer thickness parameter input by the user and the associated target room, and mark the target room according to the slope layer thickness parameter.

[0063] Example 1, create a structural roof model through Revit, click the roof command to build the roof according to the partition joints, click the conventional model in the built-in model to establish the roof layer. Select cement slag as the material for the roof top. Secondly, create a roof with a slope, name it the large roof slag slope layer, and select cement slag as the material. In the slope layer, for the exhaust duct, select a diameter of 70mm and evenly punch holes as the project feature. Select the exhaust duct as the system type. Select carbon steel as the pipe according to the drawing. Then build a 30mm thick roof leveling layer on top. The material is fine stone concrete C20. Create a roof surface layer on top, with the feature of roof surface layer and the material is asphalt. Finally, build a large roof surface layer, 30mm thick. The material is fine stone concrete C20.

[0064] After creating the relevant model, click on the details table in the view. First, create the exhaust pipe layout plan, select the project name, project characteristics, and length. Then, generate the plan of the grid seam, large roof, and small roof plans.

[0065] After BIM drawings and quantity increases, it has been applied on site. Roof deepening, using "parts" technology, can restore the uncertainty of roof slope issues to the greatest extent possible, turning it into certainty, and increasing the application rate of roof deepening optimization several times. It is also a very effective tool for large roof applications.
