Description
Technical Field
The invention belongs to the technical field of ancient building models, and particularly relates to an automatic assembling method of an ancient building model.
Background
The ancient Chinese building is the most direct existing proof of the long and long Chinese civilization culture, and the ancient official building is mainly used in the existing ancient building, namely the ancient building built by the official host of the ancient control dynasty. The ancient official buildings can be divided into two categories of 'Song style official style' and 'Qing style official style' according to different methods. The 'Qing style official' ancient building is the ancient building type which is stored in the largest quantity and has the widest distribution area in China at present. For example, ancient buildings of Beijing ancient palace Bozhou, Beijing Yonghe palace ancient buildings, Hebeichengde Sushu mountain villa ancient buildings, Shandong Kongzimo ancient buildings and the like are all 'Qing type official' ancient buildings.
From the working mode of the original domestic ancient building repair and protection industry, the cultural relic preservation and exploration design institute generally adopts the following steps for the ancient building to be repaired: 1. surveying and measuring ancient buildings on site; 2. surveying and mapping a CAD drawing of the historic building; 3. making a repairing scheme drawing according to the CAD drawing; 4. and the construction unit carries out construction according to the CAD drawing of the repair scheme. The repairing and protecting mode based on the CAD drawing of the ancient building lacks accurate cognition of multiple visual angles and multiple dimensions of the ancient building structure, single mapping and drawing of the ancient building has unicity, one drawing can not be used for multiple purposes, when the ancient buildings of multiple differences are repaired, one pair of each ancient building is required to be mapped independently, and a lot of workload is undoubtedly increased.
In order to solve the problems of the prior art that the prior art is single and cannot realize multiple purposes, BIM (building information modeling) building model software is used for replacing drawing CAD (computer-aided design) drawings, but the problems that the time and labor are very wasted when the ancient building model is assembled in the BIM software still cannot be solved by adopting the BIM building model software: because BIM software is the software that develops to modern building model, there is a set of law to the modern building spare part mounted position, though also walk in two steps: the method comprises the steps of firstly manufacturing parts and then manually dragging a part assembly model, wherein the manual assembly is simple and convenient, and each part can automatically move to a preset position only by setting the coordinate position of a building in a new project and then clicking the graph of each part, such as a column, a roof and a wall surface. However, for the application of the ancient building, the BIM software does not recognize each part of the ancient building but recognizes the part as a plug-in uniformly, for example, no matter whether the pillar, the roof and the wall are recognized as plug-ins uniformly, and when the building is manually assembled, the BIM software does not recognize whether the pillar, the roof or the wall is dragged manually at present, so that when the figures of the pillar, the roof and the wall are clicked manually, the BIM software cannot automatically position the parts to the position desired by a user, but needs to manually determine the position of each part one by one, and the position of each part is set up manually just like building block. Because all parts of the historic building are connected in a tenon structure and locked by the tenon, if the historic building with three floors needs hundreds of components and hundreds of tenons, each partial connection needs to be locked by the tenon in the manual building process, and if one part is not locked and the correction is not found in time, the hundreds of components at the back are overturned because the front part is not locked even if the building is completed. Since manual construction of an ancient building model in BIM software is very time consuming, if the time for manufacturing the ancient building model component entity is abandoned, only assembling an ancient building model is fastest and a multi-week time, even a month time is required, including the time for multiple rework reconstruction which may occur in the middle.
With the improvement of the requirement of people on the spatial dimension change of the ancient building, a user not only meets the automatic assembly of the ancient building model, but also makes any change to the model within the range allowed by the spatial dimension according to the requirement of a project, including unidirectional change and combination direction change, so that the requirement of the spatial dimension change of the model provides a more difficult problem for people, and the model needs to be reassembled every time the requirement is changed because the model cannot be copied.

i. the automatic writing of database table data of the size database of the purlin, pad, beam and sequential beam-climbing component: fig. 6a to 6c are database tables of purlin, tie plate member size, including automatic writing of three types of data: first, automatic writing of component categories: the purlin, the cushion plate, the beam and the forward climbing beam are matched with the purlin, when the type of the purlin changes, the type of the purlin size gauge, the type of the cushion plate size gauge, the type of the beam and the type of the forward climbing beam all change, the central control unit automatically identifies the change of the purlin and the change of the purlin, the cushion plate, the beam and the forward climbing beam matched with the purlin, then transmits the changed component types to the component size data unit, and the component types in the component size data table of the purlin, the cushion plate, the beam and the forward climbing beam are automatically updated by the component size data unit; secondly, automatic establishment of a table structure: the table structure of each type of component is related to the number of the opening spaces in the depth direction and the broad face direction, when the central control unit transmits the variation parameter of the number of the opening spaces to the component size data unit, the component size data unit automatically updates the table structure of the database table of the beam size, and the third step automatically writes the length of the component, the length of each type of component is matched with the number of the opening spaces and the width of the opening spaces in the depth direction and the broad face direction, the central control unit transmits the number of the opening spaces and the width of the opening spaces to the component size data unit, and the length of each type of component in the component size data unit is automatically written into the dimension table of the purlin, the beam size, the cushion plate, the beam size and the beam size.
ii. Automatic writing of the data of the ridge tree database table: the back wood support is a hexagonal prism and is arranged along the face width direction of the model, so that the length of the back wood support is related to the opening width and the opening width of the face width direction, and when a new project is built or a project is modified, the central control unit transmits the opening width and the opening number parameters of the face width direction to the component size setting data unit, so that the automatic writing of the back wood support component size database table data is completed.
Second, computer automated assembly design principle
1. The dimensional change of the model is controllable and non-stepless. Including 5 dimensional changes: the face width direction, the depth direction, the vertical direction, the slope direction and the retraction direction. The change of the collecting and releasing direction utilizes the change of the size of the hopper opening to control the whole contraction or amplification of the model according to the change of the size of the hopper opening. The bucket mouth and bucket arch relation table of each item can see the item and bucket mouth and bucket arch corresponding relation table of the basic parameter table. The change of each item selection dimension adopts a mode of selecting a drop-down box or a check box instead of adopting the operation of manual input. Each dimension change is within an allowable range. For example: the number of switches is more than or equal to 3 and less than ﹦; the number of bays must be odd; (ii) a The bay width must be a multiple of the gallery width; the sizes of the bucket openings are 12 in a conventional mode; the size of the bucket arch also defines 4 kinds.

and selecting the dimension of the change of the model, including single selection or multiple selections.
In the first embodiment, the width direction of the model increases by 2 intervals, and changes from 5 intervals to 7 intervals, while the dimension in the depth direction does not change. In this model, the broadside direction was changed from 5 to 7 intervals, with reference to the 12-column and 9-row model of fig. 13. According to the assembly rule of ancient buildings, if the bay is increased only in the broad-face direction and the bay is not increased in the depth direction, the slope surface is not changed and the length is changed. Based on this rule, when the number of the gaps in the broad-face direction of the model is increased, the number of the purlins related to the slope surface in the broad-face direction and the number of the purlins related to the slope surface in the depth direction are not changed. The only change is that the number of beams in the broadside direction is increased, 2 beams are increased due to the increase of 2 rooms, and the number of the beams is changed from 4 beams to 6 beams, so that 14 rows are provided when 7 rooms are opened in the broadside direction, wherein 1-4 rows and 10-14 rows are all rows related to a slope, and the space components on each coordinate point are unchanged. The change is that the columns of the load-bearing beams are increased from the original 5, 6, 7, 8 to 5, 6, 7, 8, 9, 10, and although 2 columns are increased, the space members of each row on the 2 columns are not changed. Take the planar-axis netlist of fig. 5a as an example: the 2 nd to 8 th rows are rows of load-bearing beams, in the 2 nd row example, when 5 rooms are opened in the broadside direction, the 5 th, 6 th, 7 th and 8 th rows of the 2 nd row are columns of the load-bearing beams, after 7 rooms are opened, the 5 th, 6 th, 7 th, 8 th, 9 th and 10 th rows of the 2 nd row are columns of the load-bearing beams, although the 9 th to 10 th columns of the 2 nd row after 7 rooms are opened are columns of the load-bearing beams, the space members corresponding to the 9 th and 10 th columns of the 2 nd row are ' 2-cornice column, 6-cornice column, 7-cornice cushion plate, 9-cornice purlin and 10-seven-frame beam ' when 5 rooms are opened, meanwhile, the space members corresponding to the 9 th to 12 th columns of the 2 nd row are moved to the 11 th to 14 th columns of the 2 nd row, and the space members corresponding to the 11 th to 14 th columns of the 2 nd row are ' 2-cornice column, 6-cornice column and seven-frame beam 7-eave cushion plate and 9-eave purlin.
For the above changes, the solution of the embodiment is: and the plane axis network data unit receives the parameters transmitted by the central control unit, recalculates the rows, columns and X, Y of the plane axis network database table, and determines the spatial components at each coordinate point of the plane axis network database table by reading the data of the model building basic rule table.
In the second embodiment, the depth of the model is increased by 2 intervals from 3 intervals to 5 intervals, and the dimension in the broad-face direction is not changed. With reference to the 12-column and 9-row model of fig. 13, the depth direction is changed from 3 intervals to 5 intervals on the basis of this model.
According to the assembly rule of ancient buildings, if the bay is increased only in the depth direction and the bay is not increased in the broad-face direction, the slope surface is changed and the length is not changed.
Based on the rule, when the number of the intervals in the depth direction of the model is increased, the plane axis network database table, the vertical elevation database table and the component size database table are changed.
1. Changes to the planar axon database table. First there will be changes in the number and kind of 3 types of members, purlin, beam, girder pier. The changes of the purlins drive the changes of the beams, which drive the changes of the girder pier.
First, purlin changes. As the slope surface changes, the depth direction of purlins related to the slope surface and the number of broad surfaces change. As 2 rooms are expanded, the number of purlins in the depth direction is increased, purlins among tips in the broadside direction are also increased, and the original 7 purlins are changed into 9 purlins. Although the number of the openings in the broad face direction is unchanged, the number of the rows of the broad faces is increased from 12 rows to 14 rows because 1 purlin is added between the tips on both sides of the broad face direction, wherein the rows 1 to 5 and the rows 10 to 14 are all rows related to the slope.
Second, beam variation. Because original 7 purlins of direction of depth are changed into 9 purlins, the width of direction of depth has increased, by the width increase, 9 purlins can not be supported to the length of original 7 roof beams, 7 roof beams can only support 7 purlins, so, still need increase a 9 roof beams below 7 roof beams, see from fig. 13, because broadside direction row number increases but the total length does not change, it is the quantity of purlin rather than the quantity of roof beam that changes, so the row number of roof beam does not change, still 4 rows, broadside direction needs to increase 4 9 roof beams (the roof beam is the full length component).
Third, a change of girders pier. It is the beamed ground that has a pier. According to the ancient building design rules, beams are supported by supporting objects, and the distance between the beams is gradually increased from bottom to top, the supporting object with the shortest distance between the beams is generally called girder (according to the structure of 3, 5 and 7 frames of beams, the supporting object between 7 and 5 is girder, the supporting object between 5 frames of 3 frames is spine, the supporting object between 3 frames of beams and the top layer of spine is spine, the height of girder pier, the height of girder and spine is gradually increased), and the supporting object between 9 frames of beams and 7 frames of beams is called girder because the newly increased 9 frames of beams are positioned at the lowest layer. To distinguish the naming effect of a newly added mound on an original mound, a lower height girder between 9 and 7 girders is called a middle girder, a lower girder between 7 and 5 girders, a girder being a middle girder, "lower middle girder" on "nine girders," middle girder "on" seven girders ".
And fourthly, components matched with purlins on the plane shaft network database table are increased, such as components of a cushion plate type, a purlin type and a forward climbing beam type are increased.
For the above changes, the solution of the embodiment is: and the plane axis network data unit receives the parameters transmitted by the central control unit, recalculates the rows, columns and X, Y of the plane axis network database table, and determines the spatial components at each coordinate point of the plane axis network database table by reading the data of the model building basic rule table.
2. The component elevation data table also changes accordingly. For the change of the component elevation data table, the solution of the embodiment is as follows: the vertical elevation data unit receives the parameters transmitted by the central control unit, corrects the algorithm of the model installation sequence algorithm unit, rearranges the installation sequence of the models, and recalculates the sizes of the epithelium and the hypodermis of each component according to the new installation sequence.
3. The component dimension database table changes accordingly. For the change of the size of the component, the solution of the embodiment is as follows: for a change in component type, the parameter update component type is passed to the component size setting unit by the central control unit. Through the transmission parameters, the purlins are added in the purlin component size table component types, the gold cushion plates are added in the cushion plate component size table component types, and the gold purlins are added in the purlin component size setting table. For a change of the table structure, the parameter update table structure is passed to the component size setting unit by the central control unit. A method of dynamically generating a table structure is employed.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention. It should be noted that modifications and embellishments within the scope of the invention may occur to those skilled in the art without departing from the principle of the invention, and are considered to be within the scope of the invention.
