Description
Technical Field
The invention relates to the technical field related to construction of structural foundations based on BIM technology, in particular to a method for rapidly acquiring a bottom contour line of a foundation slab member.
Background
In the traditional structural foundation construction, the grooving graph is required to be drawn by technicians in a CAD plane mode, the planar graph is required to be converted into three-dimensional through space imagination in the process, and then is manually drawn and output into the planar graph, so that the construction method is good for small-sized simple engineering, and if a large-sized public project is encountered, the workload is huge.
In order to facilitate drawing, a large amount of overlapping work is required in the conventional foundation trench drawing process, and a large amount of original design drawings are required to be processed during the process, which is also disadvantageous for quick output of the trench drawing. Particularly, each component of a foundation part in a complex large-scale public building is often complicated, a foundation bearing platform is staggered with a water collecting pit, a ramp, a post-pouring belt, a tower crane foundation and engineering piles, the positional relationship of the components is complex, the complex situation of pit sleeving and pit can occur in the foundation part for a structural system of an overground steel structure, the space geometric imagination is difficult to be carried out in a conventional CAD drawing mode, component drawing errors are easy to occur in the drawing process of technicians, and confusion is easy to be caused to the complex foundation components. And because the component quantity is large and the sleeve diagram is modified, the technical personnel check the difficulty is large, and the components are easy to miss. Because the drawing work is carried out on the two-dimensional plane, errors are easy to occur on complex parts of the elevation of the foundation pit, and the spatial relationship cannot be intuitively felt. Because the foundation bedplate part is often designed with more omission, once the foundation bedplate part is changed, the traditional mode can not be quickly adjusted and modified. The foundation pit excavation diagram needs to have certain diagram recognition capability, and a single plan view cannot effectively carry out bottom crossing work for workers. In the foundation stage, the field measurement department, the reinforcing steel bar department, the quality department, the production department and the professional departments all need to refer to the foundation pit grooving diagram for relevant construction operation, and the quick drawing of the construction grooving diagram is a necessary measure capable of effectively saving the construction period in the early stage of construction.
For the aspect of three-dimensional models, because the models of the steel bars and the business departments tend to lag on site, the site information cannot be comprehensively reflected, and the models cannot be referred to when the foundation pit is excavated. For BIM model, traditional foundation slab modeling is rarely combined with foundation ditch excavation equally, only establishes to foundation slab structural part, often can not establish to the surface course, and only structural part can't satisfy the grooving construction, to the huge public project of area, the deviation of a few millimeters also can have an influence to the foundation ditch excavation, later stage more extravagant concrete material. Moreover, the modeling process of the foundation slab is often performed in an internal modeling type or family mode, and the mode has the defects of being inflexible and changeable, and being incapable of being updated quickly in time once adjustment occurs. The foundation bedplate model components are concentrated at the bottom of the model, and the conventional revit pattern cannot output the bedplate model to a construction drawing capable of guiding construction.

Detailed Description
The following detailed description of embodiments of the invention is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the invention is not limited to the specific embodiments.
Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or components.
As shown in fig. 1, the method for rapidly acquiring the bottom contour of the base plate member according to the preferred embodiment of the present invention comprises the steps of:
and S1, building a foundation slab component model.
And S2, after the built foundation mat component model is rechecked, a foundation mat paving surface layer is built.

And S4, converting formats among different software to obtain required data information, and converting the required data information into a foundation slab component model and a contour type.
And S5, generating and outputting a model bottom projection line, and converting the base member bottom projection line into a base member contour line segment capable of being further deepened.
Specifically, in step S1, a foundation mat member model is built, including:
the step S11 of encoding the complex area component of the foundation slab comprises the following steps: analyzing the drawing, coding the foundation slab component in the drawing according to the flowing water section and the intersection condition, and naming the file names of the intermediate process according to the codes, so that the later tracing and integration are facilitated;
step S12, rapidly establishing a foundation slab component model by utilizing the function of the floor edge, and specifically comprising the following steps:
step S121, establishing a profile family: in order to quickly establish foundation slab model components such as a water pit and the like, the water pit is established by means of the edges of the floor slab. Three key parameters are established in the profile family: pit bottom to raft bottom height, slope angle and raft thickness. Because the foundation slab model needs to be established by combining with the field reality, and the structural design drawing and the field reality steel bar sample turning condition are combined, the profile groups are divided into an overhanging profile group and a non-overhanging profile group, and the overhanging profile groups correspond to parameterizable angle changes respectively. To accommodate for the rapid placement in a variety of scenarios, the family of profiles are categorized by 90 degrees, 60 degrees, and 45 degrees, respectively.
Wherein, overhanging profile family:
45 degrees: the method is applied to edge arrangement of the landing plate area and the edge arrangement of the civil air defense water pit;
60 degrees: is applied to most of water collection pits;
90 degrees: the method is applied to the edge position of the bearing platform and the edge position of the foundation raft;
non-overhanging family of contours:
45 degrees: slope treatment is carried out at the high and low plates;
60 degrees: the method is used for the slope of the ground beam.
Step S122, building floor edge types: comprehensively judging drawings, selecting from overhanging profile families and non-overhanging profile families, and establishing corresponding floor slab edge types;
step S123, arranging foundation members such as a water pit by utilizing the edges of the floor slab. And (4) reversely drawing the foundation slab model to create a floor slab edge example. When the water pit is drawn, the bottom plate of the water pit is drawn according to the figure by using the function of 'structure foundation-floor slab' (the positioning line of the water pit can be rapidly obtained by the mode); in the four-side building process of the water pit, each side needs to be drawn independently, the flexibility of the method is reduced by continuous drawing, the floor edges are connected into a whole, and inconvenience is brought to the building of different models of each side and the later modification and adjustment, so that special attention is paid to modeling. The 90-degree overhanging floor slab edge is flexible, not only can be connected with a foundation member, but also can be further connected with other floor slab edges, and the complex foundation parts such as the nesting of the water pit and the water pit, the nesting of the water pit and the drop plate, the nesting of the water pit and the bearing platform and the like can be quickly built by combining and connecting different floor slab edge examples.
The invention establishes the foundation slab member by using the mode of the floor slab edge, and can freely adjust the length of the floor slab edge, thereby further expanding the degree of freedom of model establishment. According to different components and different slope releasing angles, the method can be used for rapidly processing the slope releasing of other components, so that the modeling efficiency is greatly improved, the field reality is restored, and the application inaccuracy of post calculation and the like caused by insufficient model precision is avoided.
Step S13, rechecking the established foundation slab component model: and the model accuracy is ensured by multipartite checking of the established foundation mat model.
In the traditional two-dimensional deepening mode of foundation pit excavation, the staggered fusion of complex components is difficult to treat, and the deepening treatment from a structural layer to a soil layer is realized. The positions of the upper and lower mouth lines of the foundation pit excavation are completely different between the paving surface layer and the non-paving surface layer. The concrete part model is simply built far from enough, and for projects with huge field areas, if a paving surface layer is not considered, accurate field guidance is carried out without accurate foundation pit excavation diagrams, the serious waste of the later concrete amount can be caused, namely the field cannot be finely managed from the step of grooving, and the method is one of reasons for poor calculated amount of BIM foundation slabs and field existence. Secondly, if the surface layer is not considered, the later-stage steel bar construction is affected, the consumption of the steel bars is wasted, and if the shape of the foundation pit is not matched with the shape of the steel bar turning, the steel bars are required to be disassembled and changed, so that a large amount of manpower and material resources are wasted, and the time period of the subsequent foundation construction is greatly restricted. In order to accurately guide site construction, each factor affecting foundation pit excavation must be considered. Through technical communication with the actual construction site, the thickness of the surface layer is determined, and the surface layer between the main body structure and the soil layer is quickly paved by using the plug-in unit, so that an accurate deepened result can be obtained in the later period.
Specifically, in step S2, creating a foundation mat-laying surface layer includes: calculating the surface layer thickness from the structural surface to the soil layer, establishing the surface layer type, paving and drawing the surface layer, and paving the surface layer by the foundation slab as shown in fig. 2, wherein the foundation slab comprises: a bottom cladding layer 201, a side cladding layer 202, a side cladding layer floor edge 203, and a foundation slab overall cladding layer 204.
Further, in step S2, if a brick bed-jig is adopted for the member of the upright slope, the thickness of the brick bed-jig from the brick bed-jig to the soil layer is considered, and a surface layer type is established; for the pit member, the surface layer is required to be laid on each surface, and the plate bottom of the foundation plate is also required to be laid.
Wherein, the surface layer paving of the water collecting pit comprises the following steps:
s21, checking elevation of each component;
step S22, establishing a surface layer type;
step S23, drawing a side surface paving layer;
s24, utilizing the edge function of the floor slab to complement foundation components with the side edges of the water collection pit as inclined planes;
s25, drawing a paving layer at the bottom of the water collection pit;
and S26, editing the outline of the paving layer at the bottom of the water pit, and ensuring that the edge of the surface layer is outside the side paving layer.
Specifically, in step S3, viewing the overlay layer contour line in the coloring mode based on the created foundation mat overlay layer includes:
two edges 301 of the laminated layer model are reserved for later deepening positioning aiming at the side surface paving;
aiming at the intersection line 302 of the lower part of the bottom paving surface layer and the side paving surface layer, the intersection line is the lower mouth line of the foundation pit in actual foundation pit deepening, and needs to be reserved in the deepening;
aiming at the intersection line 303 of the upper part of the bottom paving layer and the side paving layer, the bottom paving layer and the side paving layer need to be deleted in depth;
aiming at the edge contour line 304 of the bottom paving laminated model, the edge contour line needs to be deleted in deepening;
aiming at the edge line segments 305 of the lateral paving laminated layers, the edge line segments need to be deleted in deepening;
aiming at the intersection line 306 of the paving surface layer of the foundation slab and the edge of the floor slab, the intersection line is the upper opening line of the foundation pit in actual foundation pit deepening, and needs to be reserved in the deepening.
When the traditional two-dimensional deepening mode meets complex and intersected base components, line segments are often required to be offset by experience and strong geometric imagination, various calculations are also required in the process, the complexity is very high, the deepening threshold and the deepening time of a foundation pit grooving deepening chart are greatly increased, the time is increased, the construction of each subsequent process is restricted, and the construction period is increased intangibly. Because the base plate member is different from other conventional structural members, in an inverted relationship, it is not possible to output a bottom projected pattern thereof for use in the undercut deepening pattern in a conventional manner. The invention innovatively explores a method for quickly acquiring the bottom contour line of a foundation slab component.
Specifically, in step S4, required data information is derived through format conversion among different software, and a base plate component model and a contour type are converted, which includes:
step S41, paving a laminated layer, and checking: and acquiring the contour lines of the foundation base plate components through Boolean intersection of the Revit model, opening a hidden line display mode in the Revit, generating intersection lines if the components are successfully fastened and subtracted, and generating wireless sections if the components are unsuccessful. By using the method, the model contour line can be checked, and line segment deletion in the later deepening stage is avoided.
Step S42, hiding the component: according to the base plate member code, confirm the region that needs the deepening, the independent frame selects the base member that needs the deepening, hides other components, only leaves surface course and connecting element, avoids the appearance interference deepening result of unnecessary lines, will carry out independent reservation with the member that deepens the position and connect.
Step S43, model data transfer processing: and (3) exporting the paving surface layer to be processed reserved in the step S42 into an SAT format, and then loading and further outputting the iges file capable of entering the Rhino in the CAD, so that the model and the linear file in the Revit are imported into the Rhino for subsequent operation processing. It should be noted that the names of the intermediate process files are named according to the basic component codes in step S41, so as to ensure the uniformity of the deepened information sources.
Specifically, in step S5, generating and outputting a model bottom projection line, converting the base member bottom projection line into a base member contour line segment capable of being further deepened, including:
step S51, importing the ies file into a rho, and changing a software display mode into a coloring mode;
step S52, performing paving surface layer color treatment: selecting a water pit paving veneer layer top plate model, and adjusting the color of a model layer to be red, so that a red contour line can be generated later, the rapid identification of subsequent deepening treatment is facilitated, and the deepening linear treatment is accelerated;
step S53, generating a component bottom projection: and selecting a model part needing to be mapped in a frame mode, and utilizing the function of establishing a 2D map view in a rho map tab, selecting a working plane option in projection, and generating a base member overlook projection view consistent with the bottom of the water pit. The method greatly improves the efficiency, can quickly acquire the projection plane view of the bottom model, and can be widely applied to other situations.
Step S54, the intersection line coloring treatment of the bottom paving and the side paving: and the color of the intersecting line layer of the top plate is adjusted to be green, so that judgment in the late deepening process is facilitated.
Step S55, outputting two-dimensional data: selecting the top projection view, clicking the file tab to export with the base point, selecting the base point, and exporting the top projection view. The derived conversion line types of the foundation mat components are respectively in one-to-one correspondence with line segments in the foundation mat laying surface layer creating step.
The derived foundation mat component conversion patterns are in one-to-one correspondence with the laying surface layer patterns in the foundation mat laying surface layer creating step, respectively. Wherein, in the transformation line type of the foundation slab component, two line segments corresponding to the side surface paving surface layer model side line 301 can be reserved for positioning in the later deepening. The line segment corresponding to the intersection line 302 of the lower part of the bottom paving surface layer and the lower part of the side paving surface layer in the foundation slab component conversion line type is a foundation pit lower opening line, the mark in Rhino is green, and the later deepening is reserved.
