[0002] With the development of economy, the construction cost industry has been paid more and more attention, which is reflected in all aspects of social economy and life, that is, the construction cost has received unprecedented attention from government-invested projects, enterprise-invested projects, foreign-funded projects, individual-invested projects and construction contractors. At this stage, whether it is investment estimation, budget estimate, budget, or settlement, they are all closely related to "construction quantity", and there is no construction cost that can exist independently of "construction quantity". Therefore, in order to determine and control the construction cost, it is necessary to pay strong attention to the extremely important basic quantity calculation work in construction cost management.

[0039] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the description of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] In the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", "connection" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0041] The directions or positional relationships indicated by terms such as “upper”, “lower”, “left”, “right”, “front”, “back”, “top”, “bottom”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the inventive product is usually placed when used. They are only for the convenience of description and simplified description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0042] The terms "first", "second", "third", etc. are merely used to distinguish elements of similar nature, and do not indicate or imply relative importance or a particular order.

[0043] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0044] See also Figure 1 The BIM modeling method for the hollow column of the steel-concrete structure provided by the present invention comprises the following steps:

[0045] S1, define and edit the overall height, elevation and longitudinal reinforcement of the column component.

[0046] See also Figure 2 and Figure 3 , the above steps may further include:

[0047] S101, defining the overall height and elevation of the column component, wherein the column component comprises a plurality of column longitudinal bars, and the plurality of column longitudinal bars are divided into side bars and corner bars according to different positions.

[0048] S102, editing the column longitudinal reinforcement according to the properties of the side reinforcement and the corner reinforcement respectively.

[0049] It can be understood that the overall height of the hollow column can be set to a top elevation of 1.500m and a bottom elevation of -4.00m, the elevation can be at a position of -3.200m, the corner reinforcement is the column longitudinal reinforcement at the corner position, and the side reinforcement is the column longitudinal reinforcement other than the corner reinforcement that constitutes the column component.

[0050] S2, dividing the column component as a whole into a plurality of sub-column segments, constructing and stacking the sub-column segments to form the column component.

[0051] The above steps may further include:

[0052] S201, arranging, calculating, adjusting and locking the column graphic elements according to the column plan layout diagram to form a plurality of column segments;

[0053] S202, stacking a plurality of the column segments to form the column member.

[0054] It can be understood that the column element can be self-owned, which can be a standard part. The column plan layout has the coordinate position of the column component. The column element is arranged at the corresponding position according to the coordinate position. After editing, the column element can be locked. The height of the column element can be consistent with the elevation, that is, -4.00m to -3.200m. The elevation of the column element is adjusted after locking to prevent the generated column longitudinal reinforcement from being calculated twice in subsequent operations, resulting in incorrect column longitudinal reinforcement data, and to provide drawing space for other steel bar attribute column component elements in the subsequent elevation range. The column longitudinal reinforcement element is called, and the corresponding coordinate position is edited, and then the column longitudinal reinforcement element is locked. The overall elevation is adjusted after locking to prevent the generated column longitudinal reinforcement from undergoing secondary calculation in subsequent operations, resulting in incorrect column longitudinal reinforcement data, and to provide drawing space for other steel bar attribute column component elements in subsequent elevation ranges (wherein, the column longitudinal reinforcement includes angle reinforcement 4C25 and side reinforcement 10C25), thereby forming the column longitudinal reinforcement. The subsequent stirrups only consider the foundation range (1C10, 2*2 stirrups). It can be known that it can be divided into a corresponding number of column segments according to actual needs, the division can be based on the size of each area of ​​the hollow column or other requirements, and the superposition can be based on its own height range and coordinate position.

[0055] See also Figures 9 to 10 , S3, define and edit the hollow column.

[0056] The above steps may further include:

[0057] S301, selecting a hollow column structure element;

[0058] S302: Define and edit the hollow column structure element according to the column plan layout drawing to obtain the hollow column structure section.

[0059] It can be understood that according to the column plan layout, the dimensions of the hollow steel-concrete column section (hollow circle diameter 600mm) are set in the special-shaped section editor, the bottom elevation is set to -0.300m and the top elevation is set to 1.500m in the property list, and then the hollow steel-concrete column element is arranged in the corresponding position according to the column component plane position diagram, and the concrete engineering quantity after removing the hollow part is calculated and summarized. The purpose of this step is to complete the modeling of the hollow column of the top steel-concrete structure, and combine it with the built-in stirrups of the 1-1 section to form a BIM model of the hollow column of the steel-concrete structure with 1-1 section stirrups, and finally obtain an integral composite component and obtain all its engineering data after spatial combination within the full height range.

[0060] S4, edit the definition of stirrups for several column segments and hollow column structural sections respectively.

[0061] The above steps may further include:

[0062] S401, respectively determining the elevation intervals of the column segments and the hollow column;

[0063] S402, respectively, editing the definition of stirrups for the column segment and the hollow column structure section according to the corresponding elevation intervals.

[0064] It is understood that in the case of two column segments, the two column segments are edited separately, see Figure 4 and Figure 5 ,②1a-1a section definition settings: Edit and define the properties of the column components in the height range of -3.200 to -0.300m (1a-1a section), set 6*6 stirrups C10@100, set the bottom elevation to -3.200m, and the top elevation to -0.300m. After the definition is completed, arrange the 1a-1a section column at the top elevation of the foundation column according to the column plan layout, summarize and calculate the stirrup engineering quantity in the range of -3.200m to -0.300m, lock the column component element, and adjust the top elevation of the column component element to -2.000m. The purpose of this step is to complete the calculation of the stirrup engineering quantity of the column components in the height range of -3.200m to -0.3000m, and prevent the secondary calculation of the stirrups in this height range from deviating from the original layout range, and reserve layout space for the 1-1 section column components (-2.000m to -0.300m);

[0065] Please refer to 11, S5, spatially combine the column member, stirrups and hollow column to form an integral column member element containing a hollow column.

[0066] It can be known that an overall spatial combination can be performed based on the coordinate information of the column component, column longitudinal reinforcement, stirrups and the hollow column itself, thereby forming an overall column component element containing a hollow column.

[0067] From the above description, it can be known that the BIM modeling method for hollow columns of steel-concrete structures provided by the present invention corresponds and associates different sections of the hollow columns of steel-concrete structures according to elevation ranges, and edits and defines them according to the attributes of column components at different elevations, especially the drawing of the hollow column part of the steel-concrete structure. After the calculation is completed, a composite component is formed by adjusting the heights of column components at different elevations and superimposing them, thereby ensuring the integrity of the BIM model of the hollow columns of steel-concrete structures and the accuracy of the engineering quantity, and solving the problem that the current BIM computer software cannot model and calculate the quantity of special-shaped components and complex nodes such as hollow columns of steel-concrete structures.
