Description

Construction project template looks unfamiliar into system and method, row's modular system and method

Technical field

The invention belongs to construction project row mould technical field, relate to a kind of row's modular system of construction project gang form, particularly relate to a kind of construction project gang form fully-automatic intelligent entirety row modular system, the present invention also discloses a kind of construction project gang form fully-automatic intelligent entirety row modeling method; Meanwhile, the invention still further relates to a kind of construction project template and look unfamiliar into system and method.

Background technology

Along with the continuous progress of engineering construction and administrative skill, be raising efficiency, improve quality level, many work posts all from " building site one-shot job " to " batch production standard operation " develop.Construction project gang form adopts new material, manufacturer's standard operation, is exactly wherein one.

Construction project gang form is constructed, and will carry out template arrangement before this, and drew out and join mould figure each component, then carries out factory process and Assembling production with this.

The template arrangement of construction project gang form, is the size according to component template face, in conjunction with the standard size of building template and assembly thereof, arranges.

Completely with artificial arrangement, labour intensity is large, inefficiency, and redjustment and modification are extremely difficult.

More existing gang form auxiliary row mould software systems, by computer software instrument auxiliary row mould, export and join Mo Tu and mould material table.In existing gang form row mould assistant software, the CAD drawing of engineering can be read in software by user, and then according to the standard size of building template, the parameter of the row's of setting mould, needs with mouse choosing the component arranging mould, arranges by software is auxiliary.Software reading element needs the size in the template face arranging template, according to the standard size in building template component base, arranges, and generates corner connect template in component corner position.In the process of row's mould, according to building template specification, calculate supporting point position, generate supporting rod figure.

But these gang forms existing assist row's mould software systems to have following shortcoming:

(1) component that can assist of software is imperfect

Construction project novel compositions template batch production standard operation, will build shaping to the various component disposable integrals in agent structure floor exactly, improves construction quality.Existing gang form auxiliary row mould software systems, generally for post wall or the such large-area arrangement of plate, can not the row's of assisting mould for components such as the window that such as wafts, balcony, air-condition plate, stair.

(2) single component row mould, non-integral row mould

The entirety that construction work is made up of components such as post, wall, beam, plates, these components have various handing-over relation.Existing gang form auxiliary row mould software systems, generally can only organ timbering wall, plate, or can only organ timbering wall, can not carry out row's mould by coupled columns wall beam slab integral.In fact, the junction relation of these components is complicated, connects by various handing-over template, forms overall template system.

(3) artificial participation is many, and degree of intelligence is not high, raises the efficiency limited

Computer software, is just used to the work of raising the efficiency, and reduces hand labor intensity.Existing gang form assists row's mould software systems in the operating process of auxiliary row's mould, such as to select the component determining to need to arrange mould, or first will sequence angle position, then carry out row of position, large face etc., these all need more artificial participation, and efficiency is very low.

General ENGINEERING CAD figure, can be placed on the drawing of each each component of floor of whole engineering in a cad file, and actual do engineering be a floor then a floor do, so just need first to determine to identify the regional extent operated by extracting.Present CAD identifies converting system, generally will use drawing dividing function, be split by drawing by floor component, then carries out identification extraction.But this method has following shortcoming:

(1) this method is split original CAD figure, if need editor CAD figure in subsequent operation, drawing after singulation just cannot revert to the former figure before segmentation after editor, this is just to the damage that ENGINEERING CAD drawing causes.

(2) inefficiency, need waste time to drawing carry out arrangements split.In addition, if engineering design has change, after reloading CAD figure, also to repeat the operation split.

(3), during cutting operation, rectangular area can only be selected to split, can not operate with polygonal in form.

(4) after segmentation, a CAD drawing may be divided into tens little figure, and each Zhang little Tu will preserve, and considerably increases the size of project file, is unfavorable for storing.

In addition, existing engineering drawing management method cannot accurately identify crossbeam, longeron, and needs the manual operation carrying out complexity, cannot realize Weigh sensor.Software is extracted in present CAD identification, and when using two graph expressions for X respectively to beam and Y-direction beam, general employing copies the method for stickup, by stacked together for two figure, and then starts to identify extraction.But these softwares have following shortcoming (to be copied by Y-direction beam mark, paste X is example on beam figure):

(1) if the markup information on Y-direction beam arrangement of reinforcement and beam line side information are all copied, so paste and X on beam arrangement of reinforcement after, cause beam sideline overlap, easy identification error.

(2), if only the markup information on Y-direction beam arrangement of reinforcement is copied, so before replicate run, first the layer such as beam sideline to be hidden, turn increase operation steps like this, reduce efficiency.

(3) in the operating process of " copying ", " stickup ", need mouse in screen convergent-divergent, movement frequently, efficiency is low.

(4) the above-mentioned operation copying, paste, has damaged former figure.

In addition, existing gang form row mould software, only for the large-area row's mould of a kind of component.Such as, one shear wall, 1 parallel beam is arranged at top, has 3 beams intersected vertically, and has a post in wall.Existing gang form row mould software only can carry out row's mould in territory, large face for part wall section (away from the region of parallel beam with the beam intersected vertically).The shortcoming of existing scheme comprises: (1) accurately cannot find out the territory, face that each component needs arrangement template, and then cannot realize overall mould row; (2) overall row's mould can not be realized, not meet the needs that novel compositions template is applied.

In view of this, nowadays in the urgent need to designing a kind of new construction project row mould mode, to overcome the above-mentioned defect of existing row's modular system.
