Detailed Description
The present application is described in further detail below with reference to figures 1-4.
The embodiment of the application discloses a steel structure virtual splicing method based on BIM. Referring to fig. 1, the steel structure virtual assembly method based on BIM includes:
and S100, acquiring the names of the parts.
The parts refer to parts of each steel structure required to be used in the same steel structure project; the name is set manually. In the present embodiment, the names of the parts are manually input by a worker, and the processor acquires the names of the parts input by the worker. In another embodiment, the names of the parts are read from the design paper by the scanning software or scanning program and then transmitted to the processor, so that the processor can obtain the names of the parts.
And S200, calling corresponding common part models with the same names as the parts from the common model part library.
It should be noted that each common part model corresponds to a common part name and a set of common model parameter values. The actual structure of each part is different, so the parameter value corresponding to each part is also different, for example, for a rod-shaped steel structure part, the parameter value of the part includes length and radius; for a hook-shaped steel structural part, the parameter values for the part include length, radius and bend angle.
All parts in the same steel structure project are divided into a common part and an exclusive part, namely, when the name of at least one part in the steel structure project is the same as the name of the common part in a common model part library, the steel structure project is proved to have the common part; on the contrary, if the name of a part in the steel structure engineering is not the same as the name of a part commonly used in the common model part library, the steel structure engineering is proved to have no commonly used part and all parts are exclusive parts.
For convenience of understanding, common parts in the embodiment refer to national standards, such as screws, bolts and the like, and also refer to other parts which are required to be used in different projects, such as rods, frames, plates, brackets and the like. It will be appreciated that although each steel structure project differs, such as footprint and shape, some common parts are not used. The parts are national standard parts or common parts, and the processing technology is the same and the parts are processed repeatedly, so that the difference between each parameter value of the actual parts and the design parameter value is not large, and the actual parts are easy to control in the required range.
Because when the steel structure is virtually assembled, the design three-dimensional models of all parts need to be manufactured in advance, workers need to pour the design drawings of the corresponding parts into the system, or input various design parameter values of the parts into the system, and the design three-dimensional models of the corresponding parts are drawn through the BIM technology. And this application makes the workman need not to design three-dimensional model to the part commonly used and constructs, has reduced workman's work load, has saved the time, has improved the virtual efficiency of assembling of steel construction. And because the actual manufacturing size of the common parts is not easy to deviate from the designed size, the common part model can be directly used, the process of measuring the real parameter values of the common parts by workers is saved, and the efficiency of virtual assembly of the steel structure is further improved.
Specifically, referring to fig. 2, the steps of constructing the common model part library include:
s210, obtaining the parameter values and names of various common models of common parts.
The common model parameter values refer to parameter values which are necessary when a part is actually manufactured, and further include parameter values which are necessary when the part is drawn by using three-dimensional drawing software. The name is the common part name for the part. And the worker manually inputs the common part names of the parts and the corresponding common model parameter values.
And S220, constructing a common part model according to the parameter values of the common models through a BIM technology.
Namely, three-dimensional software in the BIM technology is used for drawing the part model.
And S230, storing the common part model, the common part name corresponding to the common part model and various common model parameter values in a mutual correlation manner.
The mutual association refers to group storage, namely, each common part model stores the common part name and the common model parameter value corresponding to the common part model in a group manner, and the corresponding common part model and the common model parameter value can be called out through the common part name.
And S240, obtaining various updating parameter values of the common part model.
And S250, covering the updated parameter values with the original common model parameter values of the corresponding common part model, and modifying the corresponding common part model according to the updated parameter values.
And S260, storing the original common model parameter values of the common part model.
Wherein steps S240 and S250 are steps of modifying an existing common part model. The situations that need to change the existing common part model include:
and updating various parameters of the common part model to keep the parameters consistent with various parameters of the corresponding parts which are actually manufactured. For example, when a part manufacturer updates production equipment or a production process of a common part, the common part with higher precision can be produced, and at this time, a common model parameter value corresponding to a common part model needs to be changed.
A worker finds that each parameter value of a certain part in a steel structure needing to be virtually assembled is approximately the same as each common model parameter value of a certain common part model, only a few specific parameter values are different, and at the moment, a designed three-dimensional model of the part can be constructed by changing the common model parameter values of the common part model, so that the worker does not need to input all the parameter values of the part once. Since the original common model parameter values are stored in step S260, the worker can recover the corresponding common part model at any time.
Referring to fig. 1, S300, a design three-dimensional model of each dedicated part except for a common part is constructed according to a design drawing through a BIM technique.
Referring to fig. 3, the step of constructing a design three-dimensional model of each exclusive part other than the common part according to the design drawing by the BIM technique includes:
s310, obtaining each exclusive model parameter value of each exclusive part in the design drawing and the name of the corresponding exclusive part.
And S320, constructing a corresponding design three-dimensional model according to the exclusive model parameter value.
S330, storing the exclusive part name of the exclusive part, the corresponding exclusive model parameter value and the corresponding design three-dimensional model into a part pre-storage library in a mutual correlation manner.
The specific model parameter value and the specific part name in step S310 may be manually input, or may be automatically entered through scanning software or a scanning program. When all the parameters in the three sets of exclusive model parameter values in the part pre-storage library are uniform and same, deleting the same three sets of exclusive model parameter values, the corresponding exclusive part names and the design three-dimensional models from the part pre-storage library, and storing the exclusive part names, the exclusive model parameter values and the design three-dimensional models of one set in the part pre-storage library into a common model part library in a mutual correlation manner. The names of the exclusive parts are different, but the parameter values of the three groups of exclusive models are completely the same, the same part is proved, and the part is judged to be common because the use times of the part exceeds three times, so the part is stored in a common model part library, and the common model part library is updated.
It should be noted that, when the number of the exclusive parts having the same exclusive model parameter value in the part pre-storage library is set to three in this embodiment, the part is determined as a common part. And in another embodiment may be five or ten.
Referring to fig. 1, S400 outputs the names of the individual dedicated parts.
In the present embodiment, step S300 and step S400 are performed in synchronization. The name of the special part is the name of the special part, the common part name is removed from all the part names, and the rest part names are the names of the special parts. Each output proprietary part name is convenient for workers to know the number and the type of parts needing to be measured.
And S500, acquiring each real parameter value of the exclusive part.
The real parameter values are measured by workers using measuring instruments such as a measuring tape, an angle gauge, a level meter, a vernier caliper and the like.
S600, changing the corresponding design three-dimensional model according to each real parameter value of the exclusive part to generate a real three-dimensional model.
S700, virtually assembling each real three-dimensional model and each common part model, and outputting a virtually assembled result.
Before step S100, step S99 is further included to output a common part name corresponding to each common part model in the common part library. The parts in the steel structure engineering are named conveniently by workers according to the format of the common part names.
The implementation principle of the steel structure virtual splicing method based on the BIM is as follows: the method comprises the steps of calling a corresponding common part model with the same name as that of a part from a common part model library, outputting the name of an exclusive part except the common part from the part, measuring the real parameter value of the exclusive part by a worker, reducing the measurement of the real parameter value of the common part, reducing the workload of the worker and improving the efficiency of steel structure pre-assembly.
