Construction method of checker brick block for hot blast stove based on bim technology

Abstract

The invention discloses a BIM (building information modeling) technology based hot blast stove checker brick block construction method. The method specifically includes step 1, customizing the content; step 2, exporting a part and material list; step 3, combining checker bricks with edges smaller than one half to form a processing map for large checker bricks; step 4, customizing integrated bricks, wherein the size of each brick is the same as the sum of the sizes of two original checker bricks; step 5, performing processing and managing in advance according to material numbers; step 6, laying the checker bricks. The BIM technology based hot blast stove checker brick block construction method has the advantages that the radius of the inner wall of a main wall of a hot blast stove and the radius of the outer wall of a combustion chamber of the hot blast stove can be adjusted according to drawings, cutting lines of the checker bricks are adjusted correspondingly, and cutting and lofting of the checker bricks are completed rapidly; standards of gaps between the checker bricks and the inner wall of the main wall of the hot blast stove as well as between the checker bricks and the outer wall of the combustion chamber of the hot blast stove can be adjusted, and checker brick processing requirements of other type stoves can be met when the radius of the outer wall of the combustion chamber is zero; the BIM technology is applied to processing and lofting of the checker bricks of the hot blast stove, so that material quantity and processing drawings can be acquired quickly, construction cost can be saved, and workload can be reduced.

Description

technical field [0001] The invention relates to a construction method, in particular to a BIM technology-based construction method of checker brick blocks for hot blast stoves, and belongs to the technical field of industrial furnace construction. Background technique [0002] The checker bricks of the regenerator of the blast furnace system hot blast stove are mostly hexagonal checker bricks with seven holes with grooved tongues on the upper and lower sides. The checker bricks at the contact between the surrounding edges and the main wall of the hot blast stove and the outer wall of the combustion chamber shall be processed in advance according to the design requirements before construction (such as Figure 9 shown). During construction, "seat according to number" and shall not be processed in the furnace. [0003] However, in the current work, the conventional drawing software CAD can only manually trim, number and label the brick pattern on the edge of the checker brick....

AI Technical Summary

Problems solved by technology

Due to the different thicknesses of the multi-section walls of the hot blast stove, the area of ​​the checker brick masonry changes accordingly, resulting in a large amount of drawing, complicated numbering, and it is difficult to "check the number". Therefore, the construction unit usually uses a flat chisel to process the hot blast stove manually. Dust measures, but those that do not meet the construction requirements cannot be selected

[0004] In addition, because the upper surface of each layer of lattice bricks is not smooth, the processed small bricks straddle the two processed bricks of the next layer, which is not stable, and some even fall over, requiring a large number of wooden wedges and round corks for reinforcement. (like Figure 10 shown)

After the hot blast furnace is baked, the wooden wedges that reinforce the edge checker bricks disappear, and some edge checker bricks are too small and slip from the edge gap, causing the overall expansion of the checker bricks to be uneven, and even the checker bricks are loose, making the upper and lower passages of the checker bricks not smooth, resulting in The heat storage efficiency of the hot blast stove is greatly reduced, and the rework cycle is increased accordingly
