In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Example one
Fig. 1 shows an implementation flow of the building detection and identification method provided in the first embodiment of the present invention, which is detailed as follows:
and S101, determining the building element to be detected in the first building information model according to the corresponding relation between the pre-stored building structure and the sampling proportion of the building element.
The building information model is a three-dimensional building model established on the basis of various relevant information data of the construction engineering project, and real information of a building is simulated through digital information.
Specifically, the building element is a load-bearing element in the building information model, and the load-bearing element of the frame structure includes a beam, a column and a foundation, taking the frame structure as an example.
Further, a certain number of building components to be detected are randomly extracted, detection cost is counted according to the detection content, and the detail of the detection cost is displayed. The statistics of the detection cost need to be determined according to the specified detection cost requirement.
And S102, obtaining a detection value of the building element to be detected according to a preset detection family.
Here, the detection family is a family unit serving a building information model detection authentication stage.
Specifically, the detection family comprises a rebound pick family, a drill core family, a penetration family, a strain gauge family of a steel structure, a drawing family of a reinforced concrete structure and the like.
The measured values of the building elements include concrete strength, section size, rebar configuration, resistance to force effect utility ratio, and the like.
And furthermore, a detection scheme is generated according to the obtained detection value of the building element to be detected, so that subsequent processing is facilitated.
And step S103, replacing the design value of the building component to be detected in the first building information model with the detection value to generate a second building information model.
And replacing the design value according to the real data detected on site to obtain the building information model corresponding to the real data.
And step S104, detecting whether the second building information model meets preset requirements.
Specifically, the detection requirement is set according to actual needs, and whether the parameters in the second building information model meet the requirement is detected.
And step S105, judging whether the first building information model is qualified or not according to the detection result of the second building information model.
Here, the analysis process and conclusions are shown, and finally all are integrated into one word report, i.e. a test identification report is generated. Therefore, many detail errors caused by human factors in the report making process can be avoided, and the efficiency and the quality of report making are ensured.
From the above description, the building detection and identification method of the invention can be seen in that the building detection and identification are carried out according to the BIM model, so that the BIM model serving in the design stage and the construction stage serves in the detection and identification stage at the same time, the detection work accuracy and efficiency are improved, the detection and identification requirements of the existing building are met, the building is appropriately reinforced and modified according to the detection and identification result, the use safety of the building is greatly improved, and the building detection and identification method is suitable for practical application.
Further, in a specific example, the preset detection family is any one or more of a springback pick family for springing back and picking a building element, a drill family for drilling a building element, and a penetration family for penetrating a building element.
Here, the rebound refers to general physical rebound, which refers to physical deformation of an object under the action of a force, and a reduction or near-reduction state physical change generated when the pressure is released. Specifically, concrete rebound is a method of using a spring-driven weight to bounce the surface of the concrete through a bounce rod (dowel bar), measuring the distance that the weight bounces back, and estimating the strength of the concrete by using the rebound value (the ratio of the rebound distance to the initial length of the spring) as an index related to the strength.
The chiseling finger for detection uses flat knives, shovel knives and other instruments to remove mortar and plaster in a fixed range, so that an internal bearing structure is exposed.
The core drilling is a method for drilling a core sample from structural concrete by using a special drilling machine, taking the core sample to a laboratory and testing to detect the strength of the concrete or observe the internal quality of the concrete.

determining a target building component sampling proportion corresponding to the first building information model according to the corresponding relation between the building structure and the building component sampling proportion;
and randomly sampling the first building information model according to the sampling proportion of the target building component to obtain the building component to be detected.
Here, random sampling guarantees the representativeness of the sample on a random basis, i.e., guaranteeing that each object in the population has a known, non-zero probability of being selected as the object under study.
Specifically, according to the building structure of the first building information model and the corresponding relation between the building structure and the sampling proportion of the building components, the corresponding sampling proportion of the target building components is determined, and meanwhile, the corresponding sampling proportion of the target building components can be adjusted according to actual conditions.
In addition, in a specific example, the building detection and identification method further comprises the following steps:
and adjusting the display color of the building element to be detected. The building element to be detected is different from other elements in the plane view and the three-dimensional view, and the subsequent processing is convenient.

Specifically, concrete rebound is a method of using a spring-driven weight to bounce the surface of the concrete through a bounce rod (dowel bar), measuring the distance that the weight bounces back, and estimating the strength of the concrete by using the rebound value (the ratio of the rebound distance to the initial length of the spring) as an index related to the strength.
The chiseling finger for detection uses flat knives, shovel knives and other instruments to remove mortar and plaster in a fixed range, so that an internal bearing structure is exposed.
The core drilling is a method for drilling a core sample from structural concrete by using a special drilling machine, taking the core sample to a laboratory and testing to detect the strength of the concrete or observe the internal quality of the concrete.
Step S202, determining a target building component sampling proportion corresponding to BIM1 according to the corresponding relation between the building structure and the building component sampling proportion in the building structure detection technical standard (GB 50344-2004).
Here, BIM1 is a BIM model in the design stage, and in the case of no model, a BIM1 model can be established according to the design depth, wherein each parameter takes a value according to the design value and specification.
Specifically, according to the building structure of BIM1 and the corresponding relationship between the building structure in 50344 and the sampling ratio of the building component, the corresponding sampling ratio of the target building component is determined, and at the same time, the sampling ratio of the corresponding target building component can be adjusted according to the actual situation.
And S203, randomly sampling BIM1 according to the sampling proportion of the target building element to obtain the building element to be detected in BIM 1.

And S208, judging that the BIM1 is qualified when the BIM2 is detected to meet the preset requirements, and otherwise, judging that the BIM1 is unqualified.
And step S209, displaying the detection and identification result and generating a detection and identification report.
All the judgment results are integrated into a word report to generate a detection and identification report, so that a plurality of artificial detail errors in the report making process are avoided, and the efficiency and the quality of the report making are ensured.
