Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to a method for rapid construction of disc-lock scaffolding uprights based on BIM technology. Background Technology

[0002] During construction, the height of the uprights in a disc-lock scaffold needs to be adjusted according to the elevation of the supporting structure. Traditional methods require manually measuring the height of each upright in CAD, which is inefficient. Therefore, this invention proposes a method using Dynamo programming to automatically adjust the height of the uprights and automatically calculate the optimal configuration for each upright, including the number of standard / non-standard sections and the length of the adjustable support inserted into the upright, thereby improving work efficiency and saving labor and time costs.

[0003] Meanwhile, this construction method improves upon current conventional on-site construction practices (the conventional practice involves workers manually rotating and inserting each adjustable bracket into the upright, with each upright having upper and lower brackets, resulting in a large workload and low efficiency). The research objective of this invention is to develop a device that allows adjustable nuts to be quickly screwed into the bolt, thereby effectively increasing the scaffolding erection speed and shortening the construction period.

[0004] In view of this, this paper studies and improves upon existing problems, and provides a method for rapid construction of disc-lock scaffolding uprights based on BIM technology. By building a 3D model of the project using BIM, the length of the support uprights for any structural form (mainly for structures with slopes) can be automatically calculated using a programming plugin. The method directly exports the upright configuration scheme: the number of standard / non-standard sections, and the length of the adjustable brackets inserted into the uprights, saving manpower and time costs. A new rotating device is used to quickly insert the brackets into the uprights. This method is simple, practical, and has high safety performance, thereby achieving the goal of rapid construction of disc-lock scaffolding uprights. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a method for rapid construction of disc-lock scaffolding uprights based on BIM technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a method for rapid construction of disc-lock scaffolding uprights based on BIM technology, comprising ordinary drilling equipment and construction method, wherein the ordinary drilling equipment is provided with a drilling head at the bottom, a vertical steel bar is connected below the drilling head, a screw rod is provided below the vertical steel bar, a nut is provided on the outside of the screw rod, a base is installed at the bottom of the screw rod, and a limiting device is sleeved on the outside of the vertical steel bar, the limiting device comprising a sleeve, a connecting block and a fixing screw;

[0007] The steps of the construction method include:

[0008] Step 1: Obtain the location of the pole type family

[0009] 1. Create a string node named "FamilyName" and set its string value to "pole type family";

[0010] 2. Using the "Family.ByName" node, enter "FamilyName" as the family name to obtain the required pole type family;

[0011] 3. Use the "Family.Types" node to get all types of this family type;

[0012] 4. Use the "All Elements of Family Type" node to retrieve instances of all types;

[0013] 5. Use the "Element.GetLocation" node to get the location of each instance;

[0014] Step 2: Draw a straight line along the Z-axis.

[0015] 1. Use the "Vector.ZAxis" node to create a vector representing the Z-axis direction;

[0016] 2. Create a number node named "Distance" and set a fixed distance value, such as 1000;

[0017] 3. Use the "List.Map" node to map the list of locations and "Distance" to the next step;

[0018] 4. Using the "Line.ByStartPointDirectionLength" node, create a straight line starting from each position, with the direction along the Z-axis and a length of "Distance";

[0019] 5. Use the "List.Flatten" node to expand the list of lines;

[0020] Step 3: Obtain the face of any primitive

[0021] 1. Use the "Select Model Element" node to select any graphic element;

[0022] 2. Use the "Element.Faces" node to get all faces of the selected element;

[0024] 1. Connect the expanded list of lines from step 2 with the list of faces obtained in step 3;

[0025] 2. Use the "Geometry.Intersect" node to calculate the intersection points of each line with the primitive surface;

[0026] 3. Use the "List.Flatten" node to expand the list of intersections;

[0027] 4. Use the "Point.Z" node to obtain the Z-coordinate value of each intersection point;

[0028] Step 5: Find the minimum Z value

[0029] 1. Use the "List.MinimumItem" node to find the intersection point with the smallest Z-coordinate value in the intersection point list;

[0030] 2. Use the "List.FirstIndexOf" node to find the index of the smallest Z value;

[0031] 3. Use the "List.GetItemAtIndex" node to get the intersection point with the smallest Z coordinate value;

[0032] Step 6: Calculate the length

[0034] 2. Use the "Vector.ByTwoPoints" node to create a vector connecting the positions and intersections;

[0035] 3. Use the "Vector.Length" node to calculate the length of the vector;

[0036] Step 7: Length Reduction

[0038] 2. Using the "Subtract" node, subtract "ReductionLength" from the length calculated in step 6 to obtain the final length;

[0039] Step 8: Adjust the height of the uprights

[0040] 1. Using the "List.Flatten" node, expand the "All Elements of FamilyType" node obtained in step 1;

[0041] 2. Using the "String" node, create a string that describes the actual height and name it "NewHeight";

[0042] Using the final length obtained in step 7, connect it to the "value" input port of the "Element.SetParameterByName" node, and use "NewHeight" as the parameter name.

Furthermore, a new rotating device is used to quickly insert the bracket into the pole, which is simple, practical, and has high safety performance, thereby achieving the goal of rapid construction of disc-lock scaffolding poles.

[0051] This invention utilizes a self-developed Python programming language to quickly calculate pole height, pole matching schemes, and engineering quantities. Combined with an innovative device, it is simple, practical, and highly safe, significantly improving construction efficiency and shortening the construction period. Attached Figure Description
