Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, and particularly relates to a brick parameterization laying method of an arc wall based on a GH plug-in. BACKGROUND

[0002] In building construction, secondary structure construction is a relatively common engineering project. When constructing some circular arc walls, the circular arc secondary infill walls constructed by using conventional size bricks (such as a size 1 brick 600mm*240mm*200mm and a size 2 brick 200mm*240mm*200mm) cannot meet the specification requirements of the outer circular arc joint width of the secondary infill walls.

[0003] Specifically, when the size 1 brick is laid, the inner joint width of the circular arc secondary infill wall is 3mm, and the outer joint width of the masonry is 23mm. When the size 2 brick is laid, the size 1 brick is cut into the size 2 brick and then laid, the inner joint width of the circular arc secondary infill wall is 3mm, and the outer joint width of the masonry is 10mm. SUMMARY

[0004] In order to overcome the defects of the prior art, the present application provides a brick parameterization laying method of an arc wall based on a GH plug-in to solve the problem that the joint width cannot meet the building specification requirements when the conventional size brick is used to construct the circular arc secondary infill wall.

[0005] To achieve the above object, the present application provides a brick parameterization laying method of an arc wall based on a GH plug-in, comprising the following steps:

[0006] obtaining the radius of the outer arc line of the arc wall;

[0007] based on the length of the standard brick and the radius of the outer arc line of the arc wall, calculating the length of the outer arc line of the brick of the arc wall;

[0008] based on the length of the outer arc line of the brick of the arc wall and the joint width of the outer side of the arc wall, obtaining the head end point and the tail end point of the first brick of the outer arc line of the arc wall;

[0009] rotating the outer arc line of the first brick by 90° with the head end point as the axis point towards the inner side of the arc wall to intersect with the inner arc line of the arc wall to obtain the head end point of the first brick of the inner arc line of the arc wall;

[0010] translating the outer arc line of the first brick to the inner arc line of the first brick with the head end point of the inner arc line of the first brick as the base point to obtain the tail end point of the first brick;

[0011] Taking the tail end point of the outer arc line of the first block as the center point, the tail end surface line of the first block is deflected by a preset length towards the head end of the block to obtain the tail end point of the inner arc line of the reshaped block, and the preset length is the mortar joint width value of the inner arc surface of the arc wall;

[0012] Connecting the head end point and the tail end point of the outer arc line of the first block, the head end point of the inner arc line of the first block, and the tail end point of the inner arc line of the reshaped block generates the contour line of the reshaped block;

[0013] Stretching the reshaped block upward along the vertical direction by a preset height generates the reshaped block, and the preset height is the height value of the standard block;

[0014] Based on the mortar joint width of the inner and outer sides of the arc wall, the first layer of blocks is arranged along the positioning line of the arc wall;

[0015] Generating blocks in staggered layers on the first layer of blocks generates a three-dimensional model of the arc wall;

[0016] Developing the three-dimensional model of the arc wall generates a two-dimensional brick arrangement drawing to guide the construction of the arc wall.

[0017] Further, when implementing the step of developing the three-dimensional model of the arc wall into a planar brick arrangement drawing, the arc surface of the three-dimensional model of the arc wall is developed into a two-dimensional brick arrangement drawing, and the number of reshaped blocks is generated.

[0018] The beneficial effects of the present application are that the block parameterization brick arrangement method for arc wall based on GH plug-in uses right trapezoidal blocks to analyze, model and batch draw the brick arrangement of arc wall masonry, to solve the problem of uneven mortar joint width between the inner and outer sides of the arc masonry wall after masonry, which does not meet the specification limit.

[0019] The block parameterization brick arrangement method for arc wall based on GH plug-in cuts the corners of planar rectangular blocks into planar right trapezoidal blocks for masonry, and cuts the corners of the labeled size blocks into 581mm masonry for masonry, to ensure that the mortar joint between the inner and outer arc masonry is 3-4mm, and only one cutting is performed on the blocks.

[0020] The block parameterization brick arrangement method for arc wall based on GH plug-in uses grasshopper to write battery packs, analyzes different radius arc walls, obtains the short side value and arrangement scheme of the right trapezoidal blocks, and develops into a planar brick arrangement drawing.

Compared with traditional design methods, GH has two biggest features: one is that the computer can automatically generate results according to the proposed algorithm by inputting instructions, and the algorithm results are not limited to models, video streaming media and visual schemes. The second is that through writing algorithm programs, mechanical repetitive operations and a large number of logical evolution processes can be replaced by computer loop operation, and scheme adjustment can also directly obtain modified results through parameter modification, which can effectively improve the work efficiency of designers.
