DETAILED DESCRIPTION

[0017] In order to make the objectives, technical solutions and advantages of the present disclosure clearer, the technical solutions in the present disclosure will be described clearly and completely below with reference to the drawings in the present disclosure. Obviously, the described embodiments are some embodiments of the present disclosure, but not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without any creative effort belong to the protection scope of the present disclosure.

[0018] In the related art, in the process of modeling the housing design, due to the diversity of the geometric characteristics of the purlins and the connection node forms, the purlins will be recognized as different components by the modeling system, thereby increasing the data amount to be processed, the system has high calculation complexity, and the accuracy of data recognition is reduced. Therefore, the present disclosure provides a housing purlin preprocessing modeling method.

[0019] Figure 1 is a flowchart schematically showing a housing purlin preprocessing modeling method according to an embodiment of the present disclosure.

[0020] As shown in Figure 1 , the housing purlin preprocessing modeling method includes operations S110-S130.

[0021] In operation S110, a classification result of each purlin is determined according to the installation position and size of each purlin.

[0022] In operation S120, based on the classification result, the structural parameters of the connection nodes of each purlin in the same classification and the arrangement parameters of the coupling parts coupled with the bracing are unified to generate a purlin data model.

[0023] In operation S130, the purlin data model is output to identify and number each purlin.

[0024] According to an embodiment of the present disclosure, the connection node can be a connection position between the purlin and the roof beam, the corner brace or other support member. In some embodiments, the connection node generally includes the purlin end, the connection plate connected with the purlin by welding or screwing, the stiffening plate, and the bolt hole provided therein and other components. In the modeling system, due to the differences in the size, diameter of the bolt hole, arrangement position and the like of the connection plate, the stiffening plate and the like, the numbering and data processing of the purlin in the subsequent modeling design are often affected by these factors, resulting in an increase in the numbering of the purlin, and further leading to the complication of data processing. Therefore, in the process of purlin modeling, the structural parameters of the connection nodes of the purlins in the same classification are set to the same structural parameters to unify the structural parameters, thereby reducing the numbering of the modeling system in the later stage, reducing the amount of data processing, and further improving the efficiency of design modeling and data processing.

[0025] The bracing is a component applied to the house structure and arranged along the roof or wall surface to improve the overall stiffness of the house.

[0026] According to an embodiment of the present disclosure, the coupling part can be a region on the purlin for fixed connection with the bracing, generally provided with bolt holes, welding holes and other connection structures to realize mechanical coupling with the bracing. In the judgment of the modeling system, even if the size and position of the purlin are the same, the spacing, number or size of the bracing connection holes such as the bolt holes or welding holes in the coupling part combined with the bracing are different, the purlins with the same function will be determined as different components, resulting in an increase in the model data generated by the modeling system. Therefore, in the process of purlin modeling, the arrangement parameters such as the spacing, number or size of the bracing connection holes in the coupling part are unified to reduce the redundant component data in the model, thereby reducing the calculation complexity of the system.

[0027] According to an embodiment of the present disclosure, after the structural parameters of the connection nodes of each purlin in each classification and the arrangement parameters of the coupling parts are unified, a purlin data model containing the geometric information and standardized parameters of each purlin is generated. In some embodiments, the purlin data model can be output to the numbering module in the modeling system for automatic identification and numbering, so as to facilitate the subsequent house structure design and subsequent construction.

[0028] Illustratively, the house purlin preprocessing modeling method of the embodiments of the present disclosure can be implemented in a computer modeling system, for example, executed on a three-dimensional modeling platform such as Tekla Structures, Revit, BIM, etc.

[0029] Through the above setting mode, the purlins are classified so that the purlins in the same classification have approximately the same function, and the structural parameters of the connecting nodes and the arrangement parameters of the coupling parts in each classification are further unified. In this way, in the subsequent identification process, each purlin under the same classification is identified as a component of the same category, reducing the amount of data to be processed and improving the accuracy of component identification.

[0030] In an illustrative embodiment, the end flange of the purlin is modeled by cutting limbs when the geometric relationship between the purlin and the connecting node meets the preset condition. The position and shape parameters of each cut limb are the same.

[0031] According to the embodiments of the present disclosure, during the modeling of the house structure, the purlin and the connecting node may interfere, at which time the end flange of the purlin needs to be modeled by cutting limbs. The preset condition can be that the spatial interference or angular deviation between the purlin and the connecting node meets the set threshold. For example, when the end of the purlin and the connecting node of the purlin support or the roof beam have spatial overlap, or the installation slope of the purlin is too large, causing the end of the purlin and the connecting surface of the connecting node not to be coplanar, it is considered that the purlin and the connecting node meet the preset condition, and the end flange needs to be cut off in the modeling process. According to the embodiments of the present disclosure, the shape parameters of the cut limbs can include the cut-off length, cut-off width, cut-off angle of the end flange, and the shape of the cutout (such as rectangle, trapezoid, bevel, round corner, etc.).

[0032] Through the above setting mode, the purlins are classified so that the purlins in the same classification have approximately the same function, and the structural parameters of the connecting nodes and the arrangement parameters of the coupling parts in each classification are further unified. In this way, in the subsequent identification process, each purlin under the same classification is identified as a component of the same category, reducing the amount of data to be processed and improving the accuracy of component identification.

[0033] Preferably, in the case where it is determined that the purlin needs to be modeled by cutting limbs, each purlin in the classification in which the purlin is located is modeled by cutting limbs to further reduce the category data amount of the purlins to be identified subsequently.

[0034] In an illustrative embodiment, the classification result of each purlin is determined according to the installation position and size of each purlin, including: determining the position classification of the purlin according to the installation position of the purlin. In the same position classification, purlins with the same length are classified into the same category to obtain the classification result.

[0035] Because the installation positions of the purlins are different, the connection modes, stress characteristics and node structures of the purlins have great differences. If the installation positions are not distinguished, the amount of data required in the identification process will be greatly increased.

[0036] According to the embodiments of the present disclosure, the position classification determined according to the installation position can classify the purlins into end position purlins, middle position purlins and high-low span position purlins, so as to distinguish the functions of the purlins from the structure and provide classification basis for the uniformity of the connection node and coupling part parameters in the subsequent process.

[0037] In an illustrative embodiment, the operation S120 includes: standardizing the design of the end node of each purlin with different connection node structure forms, so as to unify the extension length of the end of each purlin and the arrangement parameters of the connection hole of the end.

[0038] The end node is the connection node of the end of the purlin, including the end of the purlin, the connection plate connected thereto and the screw hole and other components. At the end node, the number or thickness of the gusset connection plate and the stiffener plate may have certain differences, resulting in inconsistent extension length, hole position and connection form of the end node, and further resulting in that the purlins with different end nodes are determined as different components in the identification process. Therefore, it is necessary to unify the extension length of the end of each purlin and the arrangement parameters of the connection hole of the end.

[0039] Illustratively, for the end position purlin, the node structure can be divided into two forms: one includes a gusset connection plate and a stiffener plate, and the other is a structure without a gusset connection plate and a stiffener plate. In order to ensure that the same components can be numbered uniformly in the identification process, the above two end node structures are standardized designed, so that the end of the purlin is uniformly extended to the center position of the roof beam, and two rows of bolt holes are arranged at the end to ensure that the geometric parameters of the end of each purlin remain consistent.

[0040] Illustratively, for the middle position purlin, the node structure can also be divided into two forms: one includes a gusset connection plate and a stiffener plate, and the other is a structure without a gusset connection plate and a stiffener plate. In order to ensure that the same components can be identified and numbered uniformly, the above two node structures are standardized designed, so that the end of the middle position purlin is uniformly extended to the center position of the roof beam.

[0041] Illustratively, for the purlin in high-low span position, there are two forms of bracing connecting plate and stiffener and no bracing connecting plate and stiffener. In the modeling process, the two structural forms are standardized, the geometric dimensions of the parts are unified, the end of the purlin is extended to the center position of the roof beam, a row of bolt holes is arranged at the end, and the positions of the bolt holes are kept consistent to ensure the consistency of the end structure of the same purlin, facilitating subsequent identification and modeling.

[0042] In an illustrative embodiment, the coupling part includes a bracing connecting hole adapted to be connected with the bracing. In this case, operation S120 includes: standardizing the bracing connecting hole of each purlin to keep the number, spacing and position parameters of each bracing connecting hole consistent.

[0043] In an illustrative embodiment, for the case of bracing connecting plate on the purlin, the connecting plate is set to the same size regardless of whether the connected profile is consistent.

[0044] Based on the above-mentioned housing purlin preprocessing modeling method, the present disclosure also provides a housing purlin preprocessing modeling device. The following will be combined with Figure 2 to describe the device in detail.
