DETAILED DESCRIPTION

[0033] The technical solutions of the present application are further described below in combination with the drawings and specific embodiments. The blocks in each embodiment are autoclaved aerated concrete blocks, and the size of the complete block 21 is: length: 600 mm; height: 200, 240; thickness (generally with the wall thickness, and the brick arrangement is not considered): 100, 150, 200, 300 mm. The size of the incomplete block is cut based on this.

[0034] As shown in Figures 1-10 different embodiments of the block automatic arrangement method based on BIM of the present application are to realize the arrangement of odd skin blocks (x rows) and even skin blocks (y rows) by setting six variable control block sizes to meet the specification requirements, and to meet the optimal arrangement of the brick joint in the middle. The six variable blocks are: odd skin starting block (x1) 13, odd skin ending block (x2) 14, odd skin ending second block (x3) 15, even skin starting block (y1) 16, even skin ending block (y2) 17, even skin ending second block (y3) 18, see Figures 5-7 After the horizontal arrangement is completed, the method of vertical arrangement according to the top masonry requirements is performed, and the final output of the brick arrangement result is obtained.

[0035] The specification requirements to be met are:

[0036] 1. When the block needs to be disconnected, the sawn block length should not be less than 1 / 3 of the total length of the block.

[0037] 2. When filling the masonry wall, the block should be laid in staggered joints, and the block laying length should not be less than 1 / 3 of the length of the block.

[0038] Preferably, the block laying length (staggered joint width) is equal to 1 / 2 of the length of the block.

[0039] 3. The horizontal distance between the rabbet and the nearest mortar joint is greater than 1 / 3 of the total length of the block.

[0040] A BIM-based automatic arrangement method and device for autoclaved aerated concrete blocks includes the following steps:

[0041] Step 1: Input of two structural parameters.

[0042] The input horizontal parameters include: block size, two structural arrangement requirements (mortar joint width, rabbet depth), and minimum block requirement. The vertical parameters include: design curb height, top form: vertical quoin height range or top bevel height range, and whether to select the bottommost brick (when the top brick does not meet the minimum block size, the top and bottom simultaneously borrow bricks).

[0043] Specifically, input vertical mortar joint width (t.y), horizontal mortar joint width (t.x), rabbet depth (d), input horizontal minimum block (block.min.l), vertical minimum block size (block.min.h). Design curb height (h.curb.min), top form: quoin (qf), bevel (xq), vertical quoin height range (h.qf.MIN≤h.qf≤h.qf.MAX) / top bevel height range (h.xq.MIN≤h.xq≤h.xq.MAX).

[0044] This embodiment selects a two-structure wall of a certain project as a target area, such as Figure 2 The block size is 600*240*200. The horizontal mortar joint is 6 (t.x=15mm), the vertical mortar joint is 5 (t.y=15mm), the rabbet depth is 10 (d=100mm), the minimum block meets the specification requirement, when the block needs to be disconnected, the sawn block length should not be less than 1 / 3 of the total length of the block, therefore the horizontal minimum block (block.min.l=200mm), the vertical minimum block size (block.min.h=80mm). The design curb height (h.curb.min=450mm), the top form: quoin (qf) vertical quoin joint height h.qf=30mm.

[0045] Step 2: Read the building wall in BIM that needs to be arranged

[0046] As Figure 2 shown, read the length of the two structural walls in BIM L.wall = 7000 mm, height H.wall = 2320 mm.

[0047] Step 3: Process into a simple wall that needs to be automatically arranged

[0048] 3.1 Filter out the ring beams on the wall and arrange them by elevation; filter out the construction columns and arrange them by distance from the starting point of the wall. Record and sort the collection of ring beams I = (i1, i2, … in) and construction columns J = (j1, j2, … jn) respectively.

[0049] 3.2 Identify the size (height) of the ring beam and the size (length) of the construction column, and record them in the ring beam i(h) and the construction column j(l).

[0050] 3.3 Calculate the simple wall area between ring beams i and i+1 and between construction columns j and j+1, which is the enclosed range, i.e. the simple wall, which is divided into the first simple wall 11 and the second simple wall 12 by the j(1) construction column, as shown in Figure 3 .

[0051] 3.4 Identify the new two-side boundary of the wall to be arranged, and the boundary conditions are 1) both ends are construction columns 2) one end is a construction column 3) no construction column. Calculate the length of the simple wall to be arranged, i.e. the length L of the first skin brick 7 (i.e. odd skin) to be arranged. The first simple wall 11: L = 3900 mm, the second simple wall 12: L = 2500 mm.

[0052] Step 4: Horizontal arrangement data processing, including the following steps

[0053] 4.1 Horizontal brick arrangement trial, the first block is calculated with whole bricks to calculate the number of whole brick bands with a mortar joint, the number of arrangements (N), and the remaining length (M) when arranging with whole bricks.

[0054] Boundary condition 1: N = mathfloor(L / (600+t.y)), M = L-N*(600+t.y), M interval ∈(0, 600+t.y);

[0055] Boundary condition 2: N = mathfloor((L-t.y) / (600+t.y)), M = L-t.y-N*(600+t.y), M interval ∈(0, 600+t.y);

[0056] Boundary condition 3: N = mathfloor((L-2*t.y) / (600+t.y)), M = L-2*t.y-N*(600+t.y), M interval ∈(0, 600+t.y);

[0057] withFigure 3 Take the first simple wall 11 as an example: it belongs to the case of boundary condition 2, N = 6, M = 195.

[0058] Take the second simple wall 12 as an example: it belongs to the case of boundary condition 1, N = 4, M = 40. Figure 3

[0059] 4.2 According to the value of the last remaining length M, the corresponding calculation method in the classification interval set is calculated. According to the value of the last remaining length M in the classification interval, the corresponding set is found, the calculation method is matched, and 4 of the 6 variable bricks are limited.

[0060] Specifically: the classification interval C, the laying block C1 = [0, 100), C2 = [100, 200], C3 = (200, 300], C4 = (300, 400+t.y), C5 = [400+t.y, 500+t.y), C6 = [500+t.y, 600+t.y). According to the last remaining length (M) of each wall when arranged with whole bricks, the arrangement calculation formula is selected. The M value interval can correspond to the brick arrangement scheme.

[0147] As Figure 8 Take the first simple wall 11 as an example: according to M = 195, matching formula 5.2, N1 = 4, N2 = 4, as shown in Figure 8 .

[0148] Horizontal arrangement results: the first skin 200, 600, 600, 600, 600, 600, 595.

[0149] The second skin 600, 600, 600, 600, 600, 600, 295.

[0150] As Figure 8 Take the second simple wall 12 as an example: according to M = 40, matching formula 4.1, N1 = 2, N2 = 2, as shown in Figure 8 .

[0154] When N1 = -1, x3 = 0. When N2 = -1, y3 = 0. When N1 = -2, x1 = x3 = 0.

[0155] When N2 = -2, y1 = y3 = 0, and especially when M ∈ c3 or M ∈ c4, y2 = y3 = 0.

[0156] Because N1\N2 ≥ 0, it is not a short wall, and the variable control brick does not need to be adjusted.

[0157] Step 5: vertical arrangement data processing

[0158] 5.1 On the result of step 3.2 simple wall, according to the vertical construction form deduction guide wall 2, ring beam 3, embedded joint, inclined wall 9 after wall height h. wall_2, according to the arrangement of whole brick and mortar joint, calculate the height of top brick h. top. block = h. wall_2-(Math. Floor (h. wall_2 / (h+t))).

[0159] As shown in Figure 10 , h. wall_2 = 1840mm, according to the arrangement of whole brick and mortar joint, calculate the height of top brick h. top. block = 55mm.

[0160] 5.2 Determine whether the top brick meets the minimum block requirement

[0161] h. top. block >= block. h. min

[0162] 5.3 When the top brick meets the requirements, go to step 5.4, when the top brick does not meet the requirements, output the guide wall height, adjust the ring beam height or borrow the first skin brick trial calculation suggestion, select the adjustment method by the user. As a result of adjustment and output guide wall height (h. curb), top embedded joint / inclined height (h. qf / h. xq), top brick height (h. top. block), bottom brick height (h. bottom. block). In this case, the first skin block h. bottom. block = h. top. block = 140mm.

[0163] 5.4 Vertical brick calculation, calculate even skin brick 19 (p1), calculate odd skin brick (not including the first skin brick) 20 (p2).

[0164] Specifically, p = (h. wall_2-h. top. block-h. bottom. block-2*t. x) / (240+t. x), p is odd, p1 = (p+1) / 2, p is even, p1 = p / 2, p2 = p-p1.

[0165] As shown in Figure 10 , p = 6, p1 = p2 = 3

[0166] The result of vertical brick arrangement is: the first skin (bottom skin) 140, the second skin 240, the third skin 240, the fourth skin 240, the fifth skin 240, the sixth skin 240, the seventh skin 240, the eighth skin (top skin) 140, and the top embedded joint 30.

[0169] As shown, the input module displays a selection interface containing preset parameter information, and acquires the preset parameter information selected by the user on the selection interface as the initial parameter information. Figure 12

[0170] The control parameter calculation module first identifies the simple wall range according to the input wall. Then, horizontal arrangement parameters are calculated, including the odd skin starting brick (x1), the odd skin ending brick (x2), the odd skin ending second brick (x3), the even skin starting brick (y1), the even skin ending brick (y2), the even skin ending second brick (y3), the odd skin whole brick number (N1), and the even skin whole brick number (N2). Vertical arrangement parameters include the curb height (h.curb), the top joint / tilt height (h.qf / h.xq), the top brick height (h.top.block), the bottom brick height (h.bottom.block), the even skin brick array number (p1), and the odd skin brick array number (p2).

[0171] The block arrangement module converts the calculation results of the previous step to obtain the starting position and the ending position of each brick to be built, and inputs the model arrangement interface to call the parameterizable autoclaved aerated block family in Revit to arrange the blocks according to the starting position and the ending position.

[0172] As shown, the brick arrangement statistics module counts the whole brick number, the non-whole brick specification and number, and the mortar joint volume of each simple wall in Revit. Figure 13

[0173] As shown, the section drawing module supports the user to select the built wall in the Revit interface, automatically generates a section frame, generates the wall section frame in the Revit section drawing interface, hides the redundant drawing information, and labels the whole brick, the non-whole brick, the wall length, the height, the ring beam position, and the hole position, to form the brick arrangement drawing.
