Description

Construction project template face generates system and method, row's modular system and method

Technical field

The invention belongs to construction projects to arrange mould technical field, be related to a kind of row's modular system of construction project gang form, especially It is related to a kind of construction project gang form fully-automatic intelligent and integrally arranges modular system, and the present invention also discloses a kind of construction project combination Template fully-automatic intelligent integrally arranges mould method；Meanwhile the invention further relates to a kind of construction project template faces to generate system and method.

Background technique

With being constantly progressive for engineering construction and administrative skill, it is raising efficiency, improves quality level, many work posts All from " building site one-shot job " to " batch production standard operation " develops.Construction project gang form is marked using new material, factory Quasi- operation is exactly one of them.

The construction of construction project gang form will carry out template arrangement to each component before this, and draw out matching die figure, then with this Carry out factory process and on-site assembly production.

The template of construction project gang form is arranged, and is according to the size of component dies plate face, in conjunction with building template and its group The standard size of part, arranges.

It manually arranges completely, large labor intensity, working efficiency is low, and redjustment and modification are extremely difficult.

Existing some gang form auxiliary row's mould software systems, assist row's mould by computer software tool, output is matched Mould figure and mould material table.In existing gang form row's mould auxiliary software, user can read in the CAD diagram paper of engineering soft Part, then according to the standard size of building template, the parameter of the row's of setting mould needs to arrange the component of mould, by software with mouse choosing Auxiliary is arranged.Software reading element needs to arrange the size in the template face of template, according to the mark in building template component base Object staff cun, arranges, and generates corner in component corner position and connects template.During arranging mould, advised according to building template Model calculates supporting point position, generates supporting rod figure.

But existing these gang forms auxiliary row's mould software systems have the shortcomings that it is as follows:

(1) component that software can assist is imperfect

Construction project novel compositions template batch production standard operation, seeks to the various components one in main structure floor Secondary property one-piece casting molding, improves construction quality.Existing gang form auxiliary row's mould software systems, generally directed to column wall or plate The arrangement of such large area, cannot the row's of auxiliary mould for components such as the window that such as floats, balcony, air-conditioning plate, stair.

(2) single component arranges mould, and non-integral arranges mould

The entirety that architectural engineering is made of components such as column, wall, beam, plates, these components have various handover relationships.It is existing Some gang forms auxiliary row's mould software systems, generally can only organ timbering wall, plate, or can only organ timbering wall, cannot be whole to column wall beam plate Body carries out row's mould.In fact, the junction relationship of these components is complicated, is connected, formed whole with various handover templates Template system.

(3) artificial participation is more, and degree of intelligence is not high, improves efficiency limited

Computer software is exactly used to improve efficiency work, reduces labor intensity.Existing gang form is auxiliary The row's of helping mould software systems are in the operating process of auxiliary row's mould, for example to select to determine the component for needing to arrange mould, or first to arrange Improvement Angle Position, then the row etc. of big face position is carried out, these require more artificial participations, and efficiency is very low.

The drawing of each component of each floor of entire engineering can be placed in a cad file by general ENGINEERING CAD figure, As soon as and actually doing engineering is that then a floor is done a floor, identifies the region model operated by extracting so needing first to determine It encloses.Present CAD identifies converting system, generally to use drawing dividing function, drawing is divided by floor component, then carries out Identification is extracted.But this method has the disadvantage that:

(1) this method divides original CAD diagram, if needing to edit CAD diagram in subsequent operation, is dividing Original image before segmentation can not just be reverted to after editing on drawing afterwards, this is just damaged caused by ENGINEERING CAD drawing.

(2) working efficiency is low, and needing to waste time carries out arrangement segmentation to drawing.In addition, if engineering design has altered, After reloading CAD diagram, also to repeat the operation of segmentation.

(3) when cutting operation, rectangular area can only be selected to be split, cannot be operated with polygonal in form.

(4) after dividing, a CAD diagram paper may be divided into tens small figures, and each Zhang little Tu will be saved, greatly The size for increasing project file greatly, is unfavorable for storing.

In addition, existing engineering drawing management method can not accurately identify crossbeam, stringer, and need to carry out by hand complicated Operation, cannot achieve Weigh sensor.Software is extracted in present CAD identification, uses two figures respectively to beam and Y-direction beam for X When expression, the general method pasted using duplication is stacked together by two figures, then starts identification again and extracts.But these are soft Part has a disadvantage that and (is replicated with marking Y-direction beam, for pasting X on beam figure):

(1) if by Y-direction beam arrangement of reinforcement markup information and beam line side information all replicate, paste and X match to beam After on muscle figure, causes beam sideline to be overlapped, easily identify mistake.

It (2), be first by beam side before duplication operation if only replicated the markup information on Y-direction beam arrangement of reinforcement The figure layers such as line are hidden, and are increased operating procedure again in this way, are reduced efficiency.

(3) " duplication ", " stickup " operating process in, need mouse frequently to scale in screen, be mobile, low efficiency.

(4) operation of above-mentioned duplication, stickup, has damaged original image.

In addition, existing gang form arranges mould software, just for a kind of row's mould of component large area.For example, shearing together 1 parallel beam is arranged at wall, top, has 3 beams to intersect vertically, there is a column in wall.Existing gang form row mould software is only Row's mould in big face domain can be carried out for part wall section (region far from parallel beam with the beam to intersect vertically).Existing scheme The shortcomings that include: that (1) can not accurately find out each component and need to arrange the face domain of template, and then cannot achieve whole mould row；(2) no It is able to achieve whole row's mould, is unsatisfactory for the needs of novel compositions template popularization and application.

In view of this, nowadays there is an urgent need to design a kind of new construction project row's mould mode, to overcome existing row's modular system Drawbacks described above.

Template component generation step, calculating analyzes the face domain that various components need supporting module, then enterprising in these face domains The whole row's mould of row；

Template face generation step includes:

Step S411, template face obtaining step isolates the face for needing to arrange building template according to building rule from polyhedron, Arrange that the face of template is referred to as template face；To polyhedral each face, by the angle of its normal and plumb line to determine whether cloth Template is set, template face is considered when angle is more than predetermined angle, it is replicated and separated from polyhedron；To inhomogeneity Different angles is arranged in the component of type, accurately to obtain the template face of different component；

Step S412, template surface buckle subtracts step, carries out reducing calculating to each template face separated from component polyhedron Afterwards, it can just obtain really needing the face of arrangement template；Reducing calculating is realized with the difference operation in three-dimensional Boolean algorithm, right All template faces successively carry out reducing calculating with adjacent component polyhedron, deduction does not need arrangement template according to rule is reduced Part, finally obtain the face for needing to arrange building template.

8. construction project gang form according to claim 7 arranges mould method, it is characterised in that:

It includes being subtracted more than second with the first polyhedron that the template surface buckle, which subtracts polyhedron three-dimensional boolean's difference calculation method in step, The process of face body, template surface buckle subtract step and include:

Step S4121, binary tree constitution step constructs the first polyhedron, second polyhedral space partition zone binary tree；

Step S4122, the first segmentation step successively asks friendship with the face in the second polyhedron to each face in the first polyhedron, First polyhedral face is divided into the positive and negative two parts in second polyhedral face, every part again with second polyhedral other faces Friendship is asked, two parts are similarly divided into；It successively carries out that friendship is asked to calculate with all faces in the second polyhedron in this way, by the first polyhedron Face be divided into many faces；

Step S4123, the first polyhedron processing step decomposites the face come to the first polyhedron, with second polyhedral space Subregion binary tree judges whether in second polyhedral inside；Remove if the face inside the second polyhedron, in the second multi-panel Face outside body then retains as a part of difference；

Step S4124, the second segmentation step successively asks friendship with the face in the first polyhedron to each face in the second polyhedron, Second polyhedral face is divided into the positive and negative two parts in first polyhedral face, every part again with first polyhedral other faces Friendship is asked, two parts are similarly divided into；It successively carries out that friendship is asked to calculate with all faces in the first polyhedron in this way, by the second polyhedron Face be divided into many faces；

Step S4125, the second polyhedron processing step decomposites the face come to the second polyhedron, with first polyhedral space Subregion binary tree judges whether in first polyhedral inside；Remove if the face inside the first polyhedron, in the first multi-panel Face outside body then retains as a part of difference；

Step S4126, poor face saves step, and the face in the first polyhedron, the second polyhedron as difference is saved in result multi-panel Three-dimensional boolean's difference operation is completed in body；

In the step S4121 binary tree constitution step, during constructing polyhedral space partition zone binary tree, space partition zone Each node of binary tree includes three child nodes, the respectively face of normal front portion, i.e. positive side, the negative part of normal Face, i.e. negative side and coplanar face, i.e. coplanar portions, the building method of binary tree constitution step include the following steps:

Step S41210, all faces are added to first node；

Step S41211, using first face in node as the standard flat of node, it is saved in the coplanar portion of current tree node In point, and remove the face from polyhedron；

Step S41212, following operation is made to remaining each face: judges the relationship of the face and standard flat；Completely normal just Face is then saved in positive side gusset；Negative side node is saved in the negative part of normal completely；Coplanar face is saved in coplanar portions； The face intersected with standard flat, then dividing the face with standard flat is two parts, and front portion is saved in positive side, and negative part is protected It is stored to negative side；

Step S41213, to the face of positive side, negative side part, repeat the operation of step S41211 to S41213, until not having Positive side, negative side face until；

Step S4123, in step S4125, judge that method of the face in or beyond the first polyhedron or second are polyhedral is attributed to Whether a point in face is judged polyhedral inner or outer, and judgment method includes: will each of point and space partition zone binary tree The standard flat of node is compared；If putting the positive side in standard flat, continue to judge with positive child node, if positive side does not have There is child node, then it represents that point is outside polyhedron；If putting the negative side in standard flat, continue to judge with negative side child node, such as Fruit negative side does not have child node, then it represents that point is inside polyhedron；If point judges whether on standard flat in the coplanar portion of node In facet, if being considered inside polyhedron if, otherwise it is assumed that outside polyhedron.
