Description
Technical field
The present invention relates to building and traffic engineering technical fields, and in particular to a kind of bill of quantities based on BIM model
The method for reaching and counting.
Background technique
BIM technology is quickly grown in building and traffic engineering field, using BIM technology as the computer information technology of representative
Even more become research and development direction in architectural engineering, " 2016 ~ 2020 Construction Industry Information development outline " is pointed out using BIM as core
Up-to-date information technology, become support industry technology upgrading, production method change, management mode innovation core technology.It is required that
Designing unit, construction enterprises should all grasp and realize that BIM is answered with enterprise management system and the integrated of other information technology
With.
Engineering quantity expression and statistics in BIM technology application based on BIM model are a difficult points, because different sets
The meter stage requires difference to the modeling accuracy of BIM model, some quantity can not be calculated from model, some quantity can not look for
To corresponding entity component, be beyond expression all engineering quantities in BIM model.
Summary of the invention
The method of the object of the present invention is to provide a kind of engineering quantity expression and statistics based on BIM model, this method energy
Enough engineering quantity expression and statistics realized based on BIM model, generate the bill of quantities for meeting general budget compilation needs.
The technical scheme adopted by the invention is as follows:
The method of engineering quantity expression and statistics based on BIM model, it is characterised in that:
It is realized by following steps:
Structure tree node and the one-to-one mapping relations of component are created, are quickly found out each under node or component using node
Engineering quantity is checked under the component by entity component in a model by creating the engineering quantity database with model separation
All engineering quantities, fast implement based on BIM model engineering quantity expression and statistics, generation meet general budget compilation needs
Bill of quantities.
Specifically includes the following steps:
1) the element structure tree of layout design unit, corresponding one uniquely has level concept on each component or node
LID coding；
2) when generating BIM model, corresponding LID coding is added with attribute form on each component or node；
3) all engineering quantity items in design cell are arranged；
4) unique key is encoded to LID, each engineering quantity item under each node or component is stored in the form of recording
In a database, statistic of classification is carried out to the data being stored in database profession and is summarized, the engineering for meeting speciality habit is generated
Quantity table.
In step 2, LID coding is expressed with text mode.
It is different according to model creation precision in step 3), it can be directly straight from model from the calculated engineering quantity item of model
Export is connect, the engineering quantity item that can not be calculated from model is added with attribute form.
The invention has the following advantages that
1, this method is simple and convenient, writes the coding of the LID with layer structure according to speciality habit, makees when generating BIM model
For attribute addition；
2, it is encoded according to LID, creation design cell structure tree node and component one-to-one relationship, easy-to-look-up component and structure
Engineering quantity under part, more meets speciality habit；
3, model is separated with engineering quantity database, engineering quantity database is easier to expand management, it is more efficient.
The present invention separates BIM model with engineering quantity database, benefit by adding LID encoded attributes in component
Node is associated with component with LID, to create the one-to-one relationship of each node and component, coding structure is simple, convenient
All engineering quantities under component and component are searched and located, computer is facilitated to read and identify, it is more efficient.
Detailed description of the invention
Fig. 1 is the structure tree schematic diagram of a bridge block；
Fig. 2 is the bridge abutment structure schematic diagram after addition coding；
Fig. 3 is engineering quantity schematic diagram under one pile base of abutment.
Specific embodiment
The present invention will be described in detail With reference to embodiment.
The present invention relates to the method for engineering quantity expression and statistics based on BIM model, main implementation method is as follows:
1) first by profession design cell based on, in design cell all directory nodes and component arrange, create
Build the bibliographic structure tree of the bridge.As the design cell of bridge defines: the internal relatively independent complete engineering list of bridge profession
Member, such as a bridge block, a culvert must be divided into different design cells when across different budgetary estimate paragraphs.
Such as XXX grand bridge, the bibliographic structure tree of the complete bridge is established out, structure category tree, which refers to, starts from the design cell root
The multi-layer tree of catalogue Zhongdao minimum member unit.As shown in Figure 1.
2) LID coding is carried out to each node in bibliographic structure tree or component, node and component require coding unique, LID
Coding: the orientable identity coding dictionary of Locational Identification for Dictionaries- can be adopted
With digital coding form, character express can also be used, machine-readable take is calculated for convenience and is recommended to use digital form, such as 0# platform LID-
20-100001, as shown in Figure 2；
3) all engineering quantity items in design cell are arranged, it is different according to model creation precision, it can be directly calculated from model
Quantity goes out from model as far as possible, such as volume, the area of built component, the quantity that can not be calculated from model are added with attribute form
Add, such as does not build the number of steel bars in the case of rebar model；
4) unique key is encoded to LID, each engineering quantity under each node or component is stored in the form of recording
In one database；As shown in Figure 3 such as the engineering quantity under a pile foundation；
5) it is needed according to the general budget compilation of design cell, statistic of classification remittance is carried out to data in the database of storage quantity record
Always, the bill of quantities for meeting speciality habit is generated.
The method proposed by the present invention expressed and counted based on BIM model engineering quantity, meets speciality habit, this method energy
Enough creation structure tree node and the one-to-one mapping relations of component, and can use node and be quickly found out under node or component
Each engineering quantity, by create with the engineering quantity database of model separation, can quickly realize based on BIM model
Engineering quantity expression and statistics, generate the bill of quantities for meeting general budget compilation needs.
The contents of the present invention are not limited to cited by embodiment, and those of ordinary skill in the art are by reading description of the invention
And to any equivalent transformation that technical solution of the present invention is taken, all are covered by the claims of the invention.
