Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

In the present invention, "mold matching" refers to the process of template matching for building structure modules such as walls, slabs, beams, stairs, door and window openings. Building structural modules such as stairs, doors and windows are positioned, supported, and finally formed.

Fig. 1 shows the implementation process of the model matching method of the three-dimensional space software provided by the present invention, which is described in detail as follows.

In step A, the drawing of the building is identified to confirm whether there is an error in the drawing itself.

If it is identified that there are erroneous contents in the building drawings, the technicians are prompted for the erroneous contents. After the technicians have modified the building drawings, they will re-identify until the building drawings are correctly identified.

In the present invention, in step A, the errors in the drawing itself are mainly identified, such as whether the layer is complete, whether the corresponding parts of the construction drawing and the structural drawing and other related drawings are consistent, etc., and use the corresponding annotation of the layer or drawing as the map recognition Basis or basis.

In step B, the detailed design is carried out on the building drawings identified correctly in step A, and the change information of the building structure between floors or within the same floor is identified and noted, and the detailed design drawings are obtained;

In the present invention, detailed changes in the structure of the building need to be indicated in the detailed design drawings, including but not limited to changes in the position of beams, columns, walls, panels, door and window openings, or specific dimensions or elevation changes or plate thickness Changes or reinforcement changes, etc.

After deepening the design, the design unit, construction unit, construction unit, supervision unit and other parties need to jointly confirm whether there are any errors. After the errors are corrected, the design needs to be deepened again according to the revised content until the multi-party signature confirms that the detailed design drawing is correct.

In step C, divide the flow operation area on the confirmed detailed design drawings, and classify the building structure modules required by each flow operation area.

Among them, the flow operation area is used to represent the sequence of operations in each area. For example, it is divided into 1-N operation areas, and the flow operation is performed on each operation area in the order of 1-N during operation. When classifying, classify the building structure modules in each assembly area according to the types of walls, slabs, beams, stairs, and door and window openings.

In step D, a building model is established for each building structure module according to the classification result.

In step E, user-defined template design rule information is received, thereby establishing a corresponding standard template component library for reuse in the future.

In the present invention, the template design rule information includes standard templates and non-standard templates included in the building structure, and information about the arrangement rules of the standard templates and non-standard templates in the building structure. For example, if the length of a certain wall is 10 meters, and the length of the standard formwork corresponding to the wall is 3 meters, it needs to be designed to require 3 standard formworks and 1 non-standard formwork with a length of 1 meter.

Step F, according to the established building model and the template design rule information, match the templates for each building structure module, and number all the templates according to the classification results of step C, and generate a mold matching diagram to be confirmed, wherein, the The number contains the category information to which each template belongs.

After the above steps are completed, the formwork can be configured according to the corresponding rules. After the formwork is completed, the configured formworks are numbered according to the corresponding numbering rules, which is convenient for later material management and on-site construction management, and then the initial output is output. Matching model diagram.

Step G, after the mold matching diagram to be confirmed is confirmed to be correct, generate a formal mold matching diagram and template list, and calculate the template expansion area and mold matching area of the entire construction project, as well as the materials of the template and its accessories, weight.

Based on the above-mentioned model diagrams, the designers manually check the key and difficult parts of the building, such as the changed areas identified during the deepening of the design. After confirming that it is correct, output the official mold matching diagram and the template list of the project, that is, the processing BOM table.

Step H, according to the list of templates, compare the existing inventory, according to the comparison results, list the template list and processing plan and purchase list that need new processing, and the template processing drawings that need new processing, wherein the The list of templates to be newly processed includes information on templates that do not exist in the existing inventory but are included in the list of templates.

Then, for the template list of the project, the computer automatically compares it with the inventory template data to determine how many new templates need to be newly processed, and outputs a list of templates that need to be newly processed, that is, the newly processed BOM table.

If there is a non-standard template in the newly processed template, it is necessary to output the corresponding processing drawing, that is, the template part drawing.

According to the new processing template list and its corresponding processing drawing, output the raw material purchase list.
