[0002] The construction of reinforced truss floor decking is convenient and flexible, with the advantages of fast construction period, no need to remove formwork, and saving materials. However, the materials need to be processed in advance before they can be used. Generally, due to the flat floor of a flat roof, it is relatively easy to use traditional CAD plan drawings to carry out in-depth design of reinforced truss floor decking, and it is not easy to make mistakes after the in-depth design is completed. However, when carrying out in-depth design of reinforced truss floor decking on a sloped and irregular roof, due to the irregular floor slab and different angles, it is not convenient to use traditional CAD plan drawings to carry out in-depth design, and it is not convenient to carry out fine control of the structure during the in-depth design process, which leads to errors in the construction process after the in-depth design is completed. Summary of the invention

[0003] The embodiment of the present invention provides a method for structural in-depth design of steel truss floor decking based on BIM, which uses BIM technology to finely control the slope of each plate of the sloping roof during the in-depth process. At the same time, the relevant parameters of each plate can be changed in real time, which greatly shortens the in-depth time and the probability of in-depth errors, and solves the problem that it is inconvenient to use traditional CAD plan drawings to carry out in-depth design of the steel truss floor decking structure of a sloped and irregular roof, and that errors are prone to occur after the in-depth design is completed.

[0035] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0036] like Figure 1-8 As shown, an embodiment of the present invention provides a method for structural in-depth design of a steel truss floor deck based on BIM, comprising the following steps:

[0037] Step 1: Draw the Revit structural model according to the CAD plan;

[0038] Specifically, in step 1, according to the CAD structural plan, the structural models of beams, columns and floor slabs are drawn respectively using beam, column and floor slab tools.

[0039] Step 2, add the slope of each floor slab in the Revit structural model;

[0040] Specifically, in step 2, the elevation point slope tool is used to place slope annotations on the slab surface of each floor slab on the Revit structural model according to the generated Revit structural model, so as to provide a reference for subsequent in-depth adjustments.

[0041] It should be noted that the slope marking can automatically indicate the actual slope as the slope of the floor surface changes.

[0042] Step 3, adjusting the height of the floor slab (structural slab) in the Revit structural model according to the plane slope requirements; Step 3 specifically includes the following steps:

[0043] Step 31, calculating the column top elevation according to the slope and the position of the watershed in the CAD plane drawing;

[0044] Step 32, adjusting the column elevation in the Revit structural model according to the column top elevation obtained in step 31;

[0045] The specific adjustment method is: select the column that needs to be adjusted, and modify the value of "Top Offset" in the "Properties Tab".

[0046] Step 33, adjusting the elevations of both ends of the beam according to the column top elevation in step 31;

[0047] The specific adjustment method is: select the beam that needs to be adjusted, and modify the values ​​of "Starting Elevation Offset" and "Ending Elevation Offset" in the "Properties Tab".

[0048] Step 34, adjusting the floor surface elevation according to the beam and column elevations around each floor slab, and adjusting the slope of the floor surface by adjusting the offsets of the four corners of the floor slab;

[0049] The specific adjustment method is: select the slab that needs to be adjusted, click "Modify Sub-Element" under the Modify tab, and adjust the slope of the floor slab by adjusting the offset of the four corners of the floor slab.

[0050] Step 35, after the adjustment is completed, check whether the slope of the floor slab surface marked in step 2 meets the requirements of the drawing.

[0051] Step 4, divide all the floors;

[0052] Specifically, import the CAD steel truss floor decking detailed drawing, and divide the floor slab according to the direction and module of the steel truss floor deck in the CAD steel truss floor decking detailed drawing. The specific operation is: select a floor slab, click "Create Part" in the "Modify Tab", select "Split Part" and "Edit Sketch" in turn, and divide the floor slab according to the steel truss floor deck at a certain distance.

[0053] In one embodiment, after the floor is divided, the model is checked and the slope of the floor surface is checked. If it does not meet the requirements, the height of the floor in the Revit structural model is adjusted again according to the plane slope requirements until the requirements are met and the next step is entered.

[0054] In one embodiment, after the floor is divided, the model is checked and the floor surface slope is checked. If the requirements are met, the next step is directly entered.

[0055] Step 5, annotate the elevations of all column tops and beam ends;

[0056] Specifically, in step 5, in the plan view state, use the elevation point tool in the annotation tab to measure the position where the height needs to be measured to obtain the annotation elevations of all column tops and both ends of the beam.

[0057] Step 6, export the detailed drawings.

[0058] Specifically, by adopting BIM technology, CAD drawings can be exported if necessary in the later stage, and the exported detailed drawings can guide the on-site construction.

[0059] The present invention uses BIM technology to carry out fine control of the slope of each plate of the sloping roof during the deepening process. The operation is simple, the application range is wide, the three-dimensional model is more intuitive, and the length information can be directly measured. At the same time, the relevant parameters of each plate can be changed in real time during the deepening design process, and the annotation information is updated in real time. The deepening problems can be found at any time, which greatly shortens the deepening time and the probability of deepening errors. The deepening problems can be found in advance and solved in advance, which solves the problem that it is inconvenient to use traditional CAD plan drawings to carry out the deepening design of the steel truss floor deck structure of a sloped and irregular roof and the problem that errors are easy to make after the deepening design is completed.
