Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a parametric brick arrangement method for curved wall blocks based on a GH plug-in. Background Art

[0002] Secondary structure construction is a common project in building construction. When constructing some arc-shaped walls, the arc-shaped secondary filling walls built with conventional size blocks (such as block size 1 of 600mm×240mm×200mm, block size 2 of 200mm×240mm×200mm) cannot meet the requirements of the specifications for the outer arc mortar joint width of the secondary filling wall.

[0003] Specifically, when bricks are laid with blocks of specification 1, the width of the mortar joints between the outer masonry is 23mm when the inner mortar joint width of the arc-shaped secondary filling wall is 3mm. When bricks are laid with blocks of specification 2, blocks of specification 1 are cut to form blocks of specification 2 and then laid, the width of the mortar joints between the outer masonry is 10mm when the inner mortar joint width of the arc-shaped secondary filling wall is 3mm. Summary of the invention

[0004] In order to overcome the defects of the prior art, a parametric bricklaying method for curved walls based on a GH plug-in is provided to solve the problem that the mortar joint width cannot meet the requirements of building specifications when the circular arc secondary filling wall is built with conventional size blocks.

[0005] To achieve the above object, a parametric bricklaying method for curved wall blocks based on a GH plug-in is provided, comprising the following steps:

[0006] Get the radius of the outer arc of the curved wall;

[0007] Based on the standard block length and the radius of the outer arc of the curved wall, the length of the outer arc of the block of the curved wall is calculated;

[0008] Based on the length of the outer arc line of the building blocks of the arc wall and the mortar joint width on the outer side of the arc wall, the head end point and the tail end point of the first building block of the outer arc line of the arc wall are obtained;

[0009] The outer arc line of the first building block is rotated 90 degrees toward the inner side of the curved wall with the head end point as the axis point to intersect with the inner arc line of the curved wall to obtain the head end point of the first building block of the inner arc line of the curved wall;

[0010] Taking the head end point of the inner arc line of the first building block as a base point, translating the outer arc line of the first building block to the inner arc line of the first building block to obtain the tail end point of the first building block;

[0011] Taking the end point of the outer arc line of the first building block as the axis point, the end face line of the end of the first building block is deflected toward the front end of the building block by a preset length to obtain the end point of the inner arc line of the shaping building block, and the preset length is the mortar joint width value of the inner arc surface of the curved wall;

[0012] Connecting the beginning and end points of the outer arc line of the first building block, the beginning point of the inner arc line of the first building block, and the end point of the inner arc line of the shaped building block to generate the outline of the shaped building block;

[0013] Stretching upward in the vertical direction to a preset height to generate the shaped building block, wherein the preset height is the height value of the standard building block;

[0014] Arrange the first-layer blocks along the positioning line of the curved wall based on the mortar joint widths on the inner and outer sides of the curved wall;

[0015] Generating blocks on the first layer of blocks in a staggered array layer by layer to generate a three-dimensional model of the curved wall;

[0016] The three-dimensional model of the curved wall is unfolded to generate a two-dimensional brick arrangement diagram to guide the construction of the curved wall.

[0017] Furthermore, when implementing the step of unfolding the three-dimensional model of the curved wall to generate a plane bricklaying diagram, the curved surface of the three-dimensional model of the curved wall is unfolded in a plane to generate a two-dimensional bricklaying diagram, and the number of the shaped building blocks is generated.

[0018] The beneficial effect of the present invention lies in that the parametric bricklaying method for curved walls based on the GH plug-in of the present invention uses right-angled trapezoidal blocks to analyze, model, and batch-draw the bricklaying of curved wall masonry, so as to solve the problem that the mortar joint widths on both sides of the arc after the curved masonry wall is built are uneven and do not meet the specification limits.

[0019] The parametric bricklaying method for curved walls based on the GH plug-in of the present invention cuts the flat rectangular bricks into flat right-angle trapezoidal bricks for masonry, and cuts the marked size blocks locally into 581mm masonry for masonry, thereby ensuring that the mortar joint between the inner and outer arc masonry is 3-4mm, and the blocks are only cut once.

[0020] The parametric bricklaying method for curved walls based on the GH plug-in of the present invention uses grasshopper to write a battery pack, analyzes curved walls of different radii, obtains the short side values ​​and arrangement schemes of right-angled trapezoidal blocks, and unfolds them into a plane bricklaying drawing.

[0027] S1. Get the radius of the outer arc of the curved wall.

[0028] Grasshopper (GH for short) is a visual programming language that runs on the Rhino platform. It is one of the mainstream software in the direction of data-based design, and it also overlaps with interactive design. Compared with traditional design methods, GH has two biggest features: First, by inputting instructions, the computer can automatically generate results according to the proposed algorithm, and the algorithm results are not limited to models, video streaming media, and visualization solutions. Second, by writing algorithm programs, mechanical repetitive operations and a large number of logical evolution processes can be replaced by computer loop operations, and the adjustment of the solution can also directly obtain the modification results by modifying the parameters. These methods can effectively improve the work efficiency of designers.

[0029] See also Figure 1 and Figure 2 As shown, pick up the outer arc of the wall position and get the R value.

[0030] S2. Based on the length of the standard building block and the radius of the outer arc of the curved wall, the length of the outer arc of the building block of the curved wall is calculated.

[0032] S3. Based on the length of the outer arc line of the building blocks of the arc wall and the mortar joint width on the outer side of the arc wall, the head end point and the tail end point of the first building block of the outer arc line of the arc wall are obtained.

[0035] S6. With the tail end point of the outer arc line of the first building block as the axis point, deflect the tail end face line of the first building block toward the front end of the building block by a preset length to obtain the tail end point of the inner arc line of the shaped building block, and the preset length is the mortar joint width value of the inner arc surface of the curved wall.

[0037] S8. Stretch upward in the vertical direction to a preset height to generate the shaped building block, wherein the preset height is the height value of the standard building block.

[0038] In this embodiment, the size of the shaped building block is formed by cutting a piece obliquely from one end of a standard building block. Figure 1 shown.

[0039] S9. Arrange the first-layer blocks along the positioning line of the curved wall based on the mortar joint widths on the inner and outer sides of the curved wall.

[0041] S11, unfolding the three-dimensional model of the curved wall to generate a two-dimensional brick arrangement diagram to guide the construction of the curved wall.

[0042] When implementing the step of unfolding the three-dimensional model of the curved wall to generate a plane bricklaying diagram, the curved surface of the three-dimensional model of the curved wall is unfolded in a plane to generate a two-dimensional bricklaying diagram, and the number of the shaped building blocks is generated.

[0043] The parametric bricklaying method for curved walls based on the GH plug-in of the present invention uses Grasshopper to write a battery pack, analyzes curved walls of different radii, obtains the short side value (for example, as shown in the above figure: 581mm) and arrangement scheme of the rectangular trapezoidal shaped blocks, and unfolds them into a plane bricklaying drawing.
