Description

Technical Field

[0001] The present invention relates to the field of drawing auxiliary technology, and in particular to a method for calculating the gross floor area of ​​a factory building. Background Art

[0002] The turbine room is one of the core parts of a coal-fired power plant. It is mainly responsible for converting thermal energy into mechanical energy and then converting mechanical energy into electrical energy. Therefore, a variety of key equipment are arranged in the turbine room, such as boilers, steam turbines and generators. The installation and maintenance of these equipment require multiple openings on the floor. At the same time, the main plant usually contains multiple layers, and each layer is designed according to different functional requirements, such as the distribution layer, operation layer and deoxidation layer. As a result, the main plant plane has many floor openings, and the location and size of each floor opening are different, and the height of each floor is also different;

[0003] In the process of calculating the gross floor area of ​​a building, it is necessary to classify the calculations for different floor height ranges based on the urban planning management technical regulations promulgated by various regions.

[0004] Current construction software does not have a method to quickly calculate the building area of ​​each floor height range by classification. It is necessary to manually frame the floor range of each floor and then perform manual calculations. Due to the complexity of the steam engine room space, many openings and frequent changes in equipment selection, it is easy to make mistakes in calculation. It is often necessary to repeatedly modify the gross floor area indicators for the application for the project planning license. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a method for calculating the gross floor area of ​​a factory building to solve the above problems.

[0006] The present invention provides the following technical solutions:

[0007] A method for calculating the gross floor area of ​​a factory building comprises the following steps:

[0008] Generate the outer wall outlines of each floor of the factory including openings in CAD;

[0009] Add the floor elevation attributes for each floor;

[0010] Input preset instructions in CAD, and the preset instructions call the auxiliary drawing program preset in CAD;

[0011] Execute the preset command to generate the projection range of each floor;

[0012] Execute preset commands, identify different floor heights within the projection range, determine the applicable different volumetric area coefficients, and cover them with different styles of shadows;

[0013] Execute the preset command to calculate the capacity area of ​​each floor;

[0014] Total gross floor area.

[0015] Preferably, the CAD is Tianzheng Architectural CAD.

[0016] Preferably, the outer wall contour line containing the opening is generated by the following steps:

[0017] In the floor plans of each floor of the factory building drawn in CAD, add the exterior walls as exterior wall attributes;

[0018] Enter the thickness of the exterior wall and the thickness of the exterior insulation layer.

[0019] Select each floor plan, identify the exterior wall, and generate the exterior wall outline including thickness or external insulation layer.

[0020] Add the openings of each floor slab as floor opening properties;

[0021] Select the floor plans of each floor, identify the floor openings, and generate the floor opening outlines.

[0022] Preferably, when the floor height is ≤8m, the gross floor area coefficient is 1 times; when the floor height is >8m and ≤16m, the gross floor area coefficient is 2 times; when the floor height is >16m, the gross floor area coefficient is 3 times.

[0023] Preferably, the building area of ​​each floor of the factory building is automatically calculated based on the outline of the outer wall including the opening.

[0024] The present invention has the following beneficial technical effects:

[0025] The present invention can quickly and accurately complete the calculation of the plant building area, is simple to operate, convenient, and accurate in calculation, which can effectively improve the user's mapping experience and reduce rework calculations when applying for engineering planning licenses;

[0026] During the design process, the structure and layout of the plant may be adjusted many times. The present invention can quickly respond to design changes, recalculate the built area, and help designers to timely evaluate the impact of the adjusted design on the built area, thereby enhancing the flexibility and adaptability of the design.

[0027] By setting different gross floor area coefficients according to the floor height, it is beneficial to rationally utilize the factory space and ensure that the factory design not only meets functional requirements but also does not exceed the floor area ratio or fail to meet planning conditions due to unreasonable design.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] A method for calculating the gross floor area of ​​a factory building, such as Figure 1 As shown, the following steps are included:

[0043] In Tianzheng Building CAD, select the floor plan of each floor, enter the command "SBNW", and identify the exterior wall. If the automatic identification is inaccurate, you can manually double-click the exterior wall and set the wall properties in the pop-up window. The exterior wall properties include purpose, wall thickness, and thickness of the exterior wall insulation layer. In this example, the exterior wall purpose is "exterior wall", the exterior wall thickness is 200mm, and the exterior wall insulation layer thickness is 20mm;

[0044] Step 2: After the recognition is completed, carefully check whether each wall section is correctly recognized. If the wall is incorrectly recognized, you can use the editing tool to correct it.

[0045] Step 3: Generate the outer wall contour line. Enter the command "SWDX" to automatically search for the closed area of ​​the outer wall line and generate the outer contour line of the outer wall (including wall thickness and / or external insulation layer).

[0046] Step 4: Copy the outer contour line of the exterior wall and the polyline of the floor opening to the blank area of ​​the interface, such as Figure 2-5 shown.

[0047] Step 5: Click "3D Modeling" → "Modeling Object" → "Flat Plate". Select the polyline of the outer contour of the exterior wall, then select the closed polyline as the opening in the plate, and enter the plate thickness value.

[0048] Step 6: Enter "3do" in the command line to enter "constrained dynamic viewing mode" so that you can see the floor more intuitively. Check, increase or decrease the floor openings.

[0049] Step 7: In "3D Modeling" → "3D Combination", create a new project management drawing, import and add information such as the floor plan outline and floor height of each floor.

[0050] Step 8: "3D composite building model", create a new CAD file and merge the floor combination into the new file.

[0051] Step 9: Enter the preset command in Tianzheng Architectural CAD, and the preset command calls the auxiliary drawing program preset in Tianzheng Architectural CAD;

[0052] Step 10: Execute the preset command to generate the projection range of each floor.

[0053] Step 11: Execute the preset command to identify the different floor heights within the projection range, determine the applicable different volumetric area coefficients, and cover them with different styles of shadows for cartographers to check.

[0054] Step 12: Execute the preset command to calculate the gross floor area of ​​each floor.

[0055] Examples, such as Figure 2-12 As shown:

[0056] 1. Gross floor area. In the calculation of gross floor area of ​​turbine room, it can be simplified as the product of floor projection area and gross floor coefficient.

[0057] 2. The corresponding volumetric coefficient needs to be determined based on the floor height (floor height ≤ 8m, calculated as 1 times; floor height > 8m, ≤ 16m, calculated as 2 times; floor height > 16m, calculated as 3 times);

[0058] like Fig. 9 As shown, the first floor gross floor area = the intersection of [(second floor slab - the range after the second floor slab is opened) and the range of the first floor slab] * gross floor coefficient = (391.01+60.03+55.60)*1=506.64;

[0059] like Fig.10 As shown, the second floor gross floor area = the intersection of [(third floor slab - the range after the third floor slab opening) and the range of the second floor slab] * gross floor coefficient + the intersection of [(third floor slab - the range of the third floor slab opening - the range of the intersection with the second floor slab) and the range of the first floor slab] * gross floor coefficient = (391.01 + 60.03 + 55.60) * 1 + (626.20) * 2 = 1759.04;

[0060] like Fig.11 As shown, the three-story gross floor area = the intersection of [the range of the roof panel and the third-floor slab] * the gross floor area coefficient + the intersection of [(the range of the roof panel - the intersection with the third-floor slab) and the range of the second-floor slab] * the gross floor area coefficient + the intersection of [(the range of the roof panel - the intersection with the third-floor slab - the intersection with the second-floor slab) and the range of the first-floor slab] * the gross floor area coefficient = 1132.84*2+(214.01+192.33)*3=5243.74.

[0061] The above embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
