Abstract

The present invention is specifically the method that PC rectangular beam and Cast-in-situ Beam realize materials appraisal by BIM compositional modeling；Muscle is indulged it is characterized in that: being included in BIM software to edit rectangular section and edit lower part in " attribute " function to adjust node calculating and setting；Modeling, which is drawn, edits stirrup, calculates locking pel, adjustment PC rectangle beam section height in pel marks in situ；Draw cast-in-place segment rectangle pel；The vertical muscle in PC beam lower part, waist muscle, lacing wire and stirrup and steel bar template concrete works amount, cast-in-place part upper longitudinal bar and template concrete works amount is calculated by summarizing in composite beam each section compositional modeling.This method models reinforcing bar, civil engineering, template and secondary structure by BIM while being completed at the same time in a model, and foundation BIM model and reinforcing bar three-dimensional are to construction budget clearing, test PC member reinforcing steel bar content, extraction project amount, clearly differentiation PC component and cast-in-place part project amount, specification modeling and guiding construction offer data support.

Description

PC rectangular beam and Cast-in-situ Beam realize the method that materials are estimated by BIM

Technical field

The present invention relates to the cost estimation field of construction, specifically a kind of PC rectangular beam and Cast-in-situ Beam pass through BIM reality The method that current material is estimated.

Background technique

With the development of scientific level, the moulding of building becomes increasingly complex, the scale of groups of building is increasing, and corresponding Ground, building cost are also to increase in geometry grade, especially complicated architectural image and huge scale, for tying in construction The accounting of the dosage of component and site concrete becomes increasingly complex, if coping with current extremely complicated work by the way of calculating by hand Journey scale is easy to appear the case where dosage calculates error, in this way, for owner, total Bao Fang and subcontractor, all extremely not Just.In other words, current traditional manual accounting mode can not keep up with the growth requirement of modern building industry.

Summary of the invention

Method of the invention is to overcome drawbacks described above, provide it is a kind of by BIM technology to PC rectangular beam and Cast-in-situ Beam into The method that row materials are estimated.

In order to achieve the above object, the present invention is implemented as follows:

A kind of method that PC rectangular beam realizes materials appraisal by BIM with Cast-in-situ Beam, including

Step 1, the part rectangle composite beam PC and cast-in-place part modeling:

Step 1.1, basis set drawing and model the part rectangle composite beam PC by BIM software with cast-in-place part,

Step 1.2 edits rectangular section in BIM software and edits lower part in " attribute " function and indulges muscle to adjust node calculating Setting；

Step 1.3, modeling draw and edit stirrup in pel marks in situ, calculating locks pel, adjustment PC rectangle beam section is high Degree；

Step 1.4 repeats step 1.2 ~ step 1.3 until reinforcing bar and pel reach consistent with design drawing and meet design specification It is required that；

Step 2 draws cast-in-place segment rectangle pel and that upper longitudinal bar, reinforcing bar pel are edited in " attribute " function is complete with drawing Reach consistent；

Step 3, composite beam each section compositional modeling are calculated by summarizing, show that muscle, waist muscle, lacing wire and stirrup are indulged in PC beam lower part And steel bar template concrete works amount, cast-in-place part upper longitudinal bar and template concrete works amount.

This method models reinforcing bar, civil engineering, template and secondary structure by BIM and is completed at the same time in a model simultaneously, steel Muscle can reach design specification and in-depth node requirements in BIM model, give construction budget knot according to BIM model and reinforcing bar three-dimensional Calculation, test PC member reinforcing steel bar content, extraction project amount, clearly differentiation PC component model and refer to cast-in-place part project amount, specification It leads construction and data support is provided.

Specific embodiment

The present invention is further illustrated below by way of specific embodiment.

A kind of method that PC rectangular beam realizes materials appraisal by BIM compositional modeling with Cast-in-situ Beam, including

Step 1, the part rectangle composite beam PC and cast-in-place part modeling:

Step 1.1, basis set drawing and model the part rectangle composite beam PC by BIM software with cast-in-place part,

Step 1.2 edits rectangular section in BIM software and edits lower part in " attribute " function and indulges muscle to adjust node calculating Setting；

Step 1.3, modeling draw and edit stirrup in pel marks in situ, calculating locks pel, adjustment PC rectangle beam section is high Degree；

Step 1.4 repeats step 1.2 ~ step 1.3 until reinforcing bar and pel reach consistent with design drawing and meet design specification It is required that；

Step 2 draws cast-in-place segment rectangle pel and that upper longitudinal bar, reinforcing bar pel are edited in " attribute " function is complete with drawing Reach consistent；

Step 3, composite beam each section compositional modeling are calculated by summarizing, show that muscle, waist muscle, lacing wire and stirrup are indulged in PC beam lower part And steel bar template concrete works amount, cast-in-place part upper longitudinal bar and template concrete works amount.

Since assembled architecture PC component is finished product member, modeling software is not directly against the modeling side of prefabricated member Method can only be established for cast-in-place and assembled component building and calculate cast-in-place part, cannot embody the integrality of architecture information.And By this method, the existing operating method flexible combination of software is used, in conjunction with assembled architecture drawing, carries out PC component part Modeling, obtains corresponding engineering information, and the cost and construction to PC component part have practical significance.
