Description

Technical Field

[0001] The present invention relates to the technical field of steel bar construction arrangement, and in particular to a concrete slab steel bar construction arrangement method and system. Background Art

[0002] During construction, the bottom shape of the foundation slab is very complex, and there are various slopes, such as the intersection of foundation rafts of different heights, the intersection of water collection wells of various elevations with the foundation raft, the intersection of the raft and the drainage ditch, the intersection of the raft and the independent foundation, the intersection of the raft and the foundation beam or multiple foundation components with the raft; and there are many types of floor steel bars in the above-ground part, and there are also deductions and anchoring situations at the intersection nodes of the floor slab and the slab opening, wall column beam and slab; and the design and construction drawings issued by the design institute generally only draw the foundation top plan and node section view of the foundation bottom, and there is no plan view of the bottom surface of the foundation slab. The floor slab on the ground also only gives the intersection of the floor and the various components, and the node intersection generally refers to the steel bar specification or structural description; and the on-site steel bar drawing personnel only give the material list when making the steel bar drawing. In this case, the on-site workers have the problem of not knowing where to put the processed steel bars, resulting in serious waste on site.

[0003] The existing technical solution is that if the steel bar drawing personnel are capable, they can manually draw or use CAD software to manually draw a foundation base plate diagram or floor steel bar plan layout diagram for on-site workers, and the workers can carry out on-site construction together with the steel bar material list. However, the corresponding drawing time is relatively long. The drawing personnel draw the steel bar arrangement diagram manually or use CAD software according to the construction drawing and the node diagram, but this requires the personnel to have high spatial imagination and be careful. In addition, the drawing time is relatively long and it is easy to have errors and omissions. Some construction sites even do not directly issue arrangement diagrams, but only issue steel bar material lists. Summary of the Invention

[0004] To solve this problem, we invented a concrete slab reinforcement construction arrangement method, which includes the following steps:

[0005] S1 Establish a 3D model: First, establish the relationship between each component in the steel bar cutting software based on the construction plan and node diagram to generate a 3D model;

[0006] S2 3D model calculation: Use Boolean operation technology to perform process calculations on the concrete slab reinforcement on the 3D model to obtain accurate reinforcement arrangement and calculation results;

[0007] After S3 calculation is completed, the concrete slab arrangement diagram is automatically displayed according to the calculation results.

[0008] Preferably, the components include one or more of a foundation raft, a water collection well, an independent foundation and foundation beams, and above-ground wall beams, slabs, columns, and slab reinforcements.

[0009] Preferably, the process operation includes one or more of an arrangement operation, a scanning operation and a cutting operation.

[0010] Preferably, the step S2 further includes:

[0012] 2) Use a plane scan model based on the rebar spacing to ensure that the rebar lines cover the entire concrete slab reinforcement area;

[0013] 3) Each scan will use a plane to cut the model, generating individual steel lines. When the steel lines encounter components that need to be deducted, such as water collection wells, rafts of different heights, and slab holes, they will all be cut off to expose the area where the components need to be deducted;

[0014] 4) According to the requirements of the drawing nodes or steel bar specifications: the lower steel bars are disconnected when encountering intersecting components and anchored to the specified length according to the steel bar specifications or drawing instructions. When encountering plate holes, they are directly disconnected and bent;

[0015] 5) The middle and top steel bars are directly disconnected and bent when encountering water collection wells, plate holes and other components. The ends are also anchored according to relevant specifications when encountering wall columns and beams. They can be anchored straight, not bent directly;

[0016] 6) The main reinforcement intersects vertically at the intersection of the support reinforcement and the distribution reinforcement, and the distribution reinforcement is anchored into the main reinforcement to the corresponding length according to the specifications.

[0017] Preferably, the step S3 further includes:

[0018] 1) Generate 2D plan views of the bottom, middle, and top of each component based on the 3D model, and read the elevation information of each component from the graphic properties and annotate it on the plan view;

[0019] 2) Based on the various information obtained during the calculation process, the specifications, position relationship, shape, reinforcement range, length, joint type, construction section information, disconnection of various components, and anchor length information of the concrete slab reinforcement are displayed;

[0020] 3) Merge the same steel bars within the reinforcement range, and finally display this information in the arrangement diagram.

[0021] On the other hand, the present application also relates to a concrete slab reinforcement construction arrangement system, comprising the following modules: a three-dimensional model editing module, used to establish the relationship between various components in the reinforcement cutting software according to the construction plan and the node diagram, and generate a three-dimensional model; a three-dimensional model calculation module: used to use Boolean operation technology to perform process operations on the concrete slab reinforcement on the three-dimensional model to obtain accurate reinforcement arrangement and calculation results; a display module, used to automatically display the concrete slab arrangement diagram based on the calculation results.

[0033] 11) Module for measuring the distance between two points: Measure the distance between any two points in the arrangement diagram;

[0034] 12) Output range selection module: select part of the steel bars and output reports and drawings;

[0035] 13) Specific length modification module: Adjusting the length of the first steel bar only affects the length of the last steel bar.

[0036] Preferably, the three-dimensional model calculation module includes:

[0037] 1) Scaling module: Scale the model area according to the concrete slab reinforcement area and the cover thickness;

[0038] 2) Plane scanning module: Use the plane scanning model according to the steel bar spacing so that the steel bar line covers the entire concrete slab reinforcement area;

[0039] 3) Plane cutting module: Each scan uses a plane to cut the model, generating individual steel bars. When the steel bars encounter a water collection well, they are all cut off, revealing the water collection well area.

[0063] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0064] Example 1

[0065] like Figure 1 As shown, a method for arranging reinforcement bars for concrete slab construction includes the following steps:

[0066] 1. Build a 3D model: First, build the relationship between the foundation concrete raft slab water collection well, independent foundation and foundation beam components in the reinforcement cutting software according to the construction plan and node diagram, and add the raft reinforcement of the large bottom plate to generate a 3D model, such as Figure 2-3 The raft 1, the water collection well pit 2, the slope of the bottom plate of the single water collection well 3, the slope of the bottom of the double water collection wells 4, and the slope of the bottom of the rafts of different heights 5.

[0067] 2. 3D model calculation: Using Boolean operations, we perform operations such as arranging, scanning, and cutting the concrete slab steel bars one by one on the 3D model to obtain accurate steel bar arrangement and calculation results. The specific implementation is as follows (taking the concrete slab and water collection well as an example):

[0068] 1) First, scale the model area according to the concrete slab reinforcement area and the thickness of the protective layer (such as 40mm for general raft slabs). Figure 4 The scaled graphic includes the scaled outer frame line 6, the raft 1, and the bottom shape of the water collection well 7;

[0069] 2) Then use the plane scanning model according to the steel bar spacing to make the steel bar line cover the entire concrete slab reinforcement area, such as Figure 5 As shown;

[0070] 3) Each scan will use a plane to cut the model and generate a steel bar line. When the steel bar line encounters a water collection well, it will be cut off to expose the water collection well area. Figure 6 As shown;

[0071] 4) According to the requirements of the drawing nodes or steel bar specifications: the bottom steel bar is disconnected when it meets the water collection well and extends a length to be anchored into the water collection well, such as Figure 7 As shown;

[0072] 5) The top steel bar bends down when it meets the upper opening of the water collection well and extends into the water collection well. Figure 8 As shown:

[0073] 6) The above calculation process is automatically analyzed and completed by the program, without the need for user manual operation.

[0074] 3. After the calculation is completed, the concrete slab arrangement diagram is automatically displayed according to the calculation results:

[0075] 1) Generate 2D plan views of the bottom, middle, and top of each component based on the 3D model, and read the elevation information of each component from the graphic properties and annotate it on the plan view;

[0076] 2) Based on the various information obtained during the calculation process, the specification, position relationship, shape, reinforcement range, length, joint type, construction section information, disconnection of various components, and anchorage length of the concrete slab reinforcement are displayed;

[0077] 3) Then merge the same steel bars within the reinforcement range, and finally display this information in the arrangement diagram, such as Figure 9-10 shown.

[0078] Because the on-site terrain is complex and there may be certain deviations, and the results calculated by the software are too precise, the length of each steel bar is already at the millimeter level, which may lead to a wide variety of steel bars, which is not conducive to on-site workers' material selection and construction. Therefore, it is necessary to add some quick editing functions to the arrangement diagram, and after editing, they can be updated and displayed in the report, such as the following functions:

[0079] 1) Profiling adjustment: The length of the steel bars can be adjusted, for example, within a 10mm range, so that steel bars with a length difference of 10mm are combined into the same length;

[0080] 2) Modify joints in batches: Based on the on-site construction conditions, the joint form can be modified in batches, such as changing tied joints to mechanical connections or welding joints;

[0081] 3) Drawing reinforcement: You can draw raft bottom reinforcement, middle reinforcement and surface reinforcement in the arrangement diagram;

[0082] 4) Blasting: A large number of steel bars can be blasted into two types. For example, if there are 50 steel bars of the same length, these 50 steel bars need to be blasted into two types of 25 steel bars. This can ensure the staggered joint rate on site.

[0083] 5) Joint swap: The length of the first steel bar and the tail steel bar are swapped, mainly to stagger the joints;

[0084] 6) Steel bar list: After adjusting the steel bars in the arrangement diagram, you can output the steel bar list in centimeters or millimeters for on-site construction, such as Figure 11 As shown;

[0085] 7) Export CAD: You can export CAD drawings in DWG format, such as Figure 12 As shown, it is convenient for on-site workers to use this diagram together with the report to facilitate on-site construction;

[0086] 8) Intelligent numbering: This function is very important. The number is equivalent to the unique code of the steel bar. It will also be used in reports and arrangement diagrams. The numbering needs to be carried out according to a certain order, such as numbering according to construction section, steel bar type, XY direction, from bottom to top, and from left to right. The prefix and starting number can also be set. In this way, workers can quickly and accurately place the steel bars on site after receiving the report and printed arrangement diagram.

[0087] 9) Batch modification of numbers: you can select some steel bars to renumber;

[0088] 10) Measure the distance between two points: You can measure the distance between any two points in the arrangement diagram;

[0089] 11) Output range: Since the area of ​​the foundation raft is relatively large, construction can be carried out in sections, so we can select some of the reinforcement bars to output reports and drawings;

[0090] 12) Modifying the length affects the last section: Mainly when the foundation length is too long, the steel bar is composed of steel bars of multiple lengths combined into one. Generally, except for the first and last steel bars, most of the middle ones use the fixed length of the steel bar raw materials. Therefore, we often adjust the first steel bar and only affect the length of the last steel bar, rather than the length of the second steel bar. Therefore, this command is made.

[0092] A concrete slab reinforcement construction arrangement system includes the following modules:

[0093] The 3D model editing module is used to establish the relationship between the foundation raft, water collection well, independent foundation and foundation beam, wall beam, slab column and slab reinforcement on the ground in the reinforcement cutting software according to the construction plan and node diagram, and generate a 3D model; the 3D model editing module includes: 1) template adjustment module: used to adjust the length of the reinforcement, and the reinforcement with a length difference of less than or equal to 10mm is merged into reinforcement of the same length; 2) joint modification module: batch modify the form of joints according to the on-site construction situation; 3) reinforcement drawing module: arbitrarily draw the bottom reinforcement, middle reinforcement and surface reinforcement of the concrete slab in the arrangement diagram; 4) reinforcement merging module: merge reinforcements of similar lengths; 5) explosion module: explode a large number of reinforcements into two types to ensure the staggered on-site joint rate; 6) joint alignment Adjustment module: swap the length of the first steel bar and the tail steel bar; 7) Steel bar list module: after adjusting the steel bars in the arrangement diagram, output the steel bar list for on-site construction; 8) Export CAD module: export CAD drawings in DWG format; 9) Intelligent numbering module: the number is the unique code of the steel bar, which will also be used in reports and arrangement diagrams, and needs to be numbered according to a certain order, and the prefix and starting number format must be set; 10) Batch modification numbering module: select some steel bars and renumber them; 11) Measure the distance between two points module: measure the distance between any two points in the arrangement diagram; 12) Output range selection module: select some steel bars and output reports and drawings; 13) Specific length modification module: adjust the length of the first steel bar, which only affects the length of the last steel bar.

[0094] Three-dimensional model calculation module: used to use Boolean operation technology to perform process operations on the concrete slab steel bars on the three-dimensional model to obtain accurate steel bar arrangement and calculation results; the three-dimensional model calculation module includes: 1) scaling module: scaling the model area according to the protective layer thickness based on the concrete slab steel bar reinforcement area; 2) plane scanning module: using the plane scanning model according to the steel bar spacing so that the steel bar line covers the entire concrete slab steel bar reinforcement area; 3) plane cutting module: each scan will use the plane cutting model to generate a single steel bar line, and when the steel bar line encounters a water collection well, all are disconnected to expose the water collection well area; 4) anchoring module: according to the requirements of the drawing node or steel bar specification: the bottom steel bar is disconnected when it encounters the water collection well and extends a length to be anchored in the water collection well, and the top steel bar is bent down when it encounters the upper opening of the water collection well and extends to the inside of the water collection well.

[0095] The display module is used to automatically display the concrete slab arrangement diagram based on the calculation results.

[0096] Example 3

[0097] A method for arranging steel bars for concrete slab construction comprises the following steps:

[0098] 1. Build a 3D model: First, draw two different rafts according to the construction plan and node diagram, and then set the rafts with variable cross-sections. For example, one raft is 500 thick and has a top elevation of -3.050 meters; the other raft is 800 thick and has a top elevation of -3.250 meters. Select the two rafts to set variable cross-sections. Set the variable cross-sections, such as Figure 13 As shown. The slab with lower bottom elevation needs to be extended 600° to the bottom of the slab with higher bottom elevation and sloped 45 degrees. The upper part does not extend. In this way, the plane position of the bottom of the slab with lower elevation will change. After setting the nodes at the variable cross-section, the raft bottom reinforcement, middle reinforcement and raft bottom reinforcement are arranged on it to form a three-dimensional model as shown. Figure 14 shown.

[0099] 2. 3D model calculation: Boolean operations are also used to perform operations such as arranging, scanning, and cutting the concrete slab steel bars one by one on the 3D model to obtain accurate steel bar arrangement and calculation results. The specific implementation is as follows (taking two concrete slabs of different thicknesses as an example):

[0100] 1) First, scale the model area according to the concrete slab reinforcement area with a protective layer of 40mm. Then, use a plane to scan the bottom area of ​​the model based on the reinforcement spacing. When the bottom elevation (-3.250 meters) is found to have a slope, extend directly along the bottom area in the direction of the slope and cut off the slab at -3.050 meters along the angle, and anchor the bottom reinforcement into another raft slab. Figure 15 shown.

[0101] 2) Then process another area with a higher bottom elevation (-3.050 meters). When scanning another plate area with a lower bottom elevation, perform the same plane cutting and anchor it into the plate at -3.250 meters. Figure 16 shown.

[0102] 3) The same approach is taken for the top reinforcement. Scan according to the spacing, and then the plate reinforcement with a lower elevation is extended into the one with a higher elevation for anchoring. Conversely, the higher one bends down when it meets the lower one and is anchored with the plate reinforcement with a lower elevation. Figure 17 shown.

[0103] 4) When there is a middle steel bar in the middle, the steel bar area is formed by the average distribution of the plate thickness where the middle steel bar is located. The calculation method is the same as the top steel bar. The steel bar nodes formed are as follows: Figure 18 shown.

[0104] In another embodiment, when the raft area is too large and there are multiple combinations of water collection wells and variable cross-section rafts, the zoning construction method is used to divide the area for segmented construction. The joints of the steel bars in the area to be constructed first are reserved. The calculation method of the steel bars in the area is the same as above. The effect of one of the blocks is as follows: Figure 19-20 shown.
