Description
Technical field
The present invention relates to architecture construction technical field, more particularly to a kind of food for being modeled based on BIM, not setting post-cast strip
Freezer large area overlength method for constructing terrace.
Background technology
Food stuff refrigerated storage is the building for food product refrigeration and refrigeration, and it is the method by artificial cooling, makes Ku Neibao
Certain low temperature is held, therefore it is required that can guarantee that freezer has good heat-insulating property after construction.
Newly-laid concrete can shrink during scleroma, and built structure is heated to be expanded, and be cooled, shrink.Concrete
Scleroma is shunk most of by completion in first 1~2 month after construction, and effect of the temperature change to structure is then frequent.
When its deformation suffers restraints, temperature stress is just produced in inside configuration, will occur crack when serious in component, and crack
Generation be significant adverse to heat preservation of refrigeration storage.
Traditional prevents method caused by crack to set post-cast strip method.Post-cast strip is set in construction, is built in long
Build in thing, width is set every 30~40 meters as 700~1000 millimeters of seam, reinforcing bar is using overlap joint or straight-through plus curved way in seam.
After reserving post-cast strip, concrete can be with free shrink, so as to greatly reduce shrinkage stress in work progress.The tension of concrete
Intensity can largely be used for resisting temperature stress, improve the ability of structure resistance temperature change.
Although pouring post-cast strip concrete to preventing terrace cracking effective by design requirement, brought to construction many tired
It is difficult：It is that exterior sheathing and support can not remove in time first, causes template turnover slow；Next to that the raked joint of post-cast strip is more troublesome,
Increase extra process to construction, thus extend project progress.Also, for this special building of freezer, post-cast strip is set
It is unfavorable for ground insulating performance.
BIM (Building Information Modeling, abbreviation BIM) is with construction-engineering project
Based on every relevant information data, it is established that three-dimensional BUILDINGS MODELS, had by digital information analogue simulation building
Some real informations.It has information completeness, information relevance, consistency on messaging, visualization, harmony, simulation, optimization
Property and eight big feature of figure can be gone out.By the project participant such as construction unit, designing unit, unit in charge of construction, supervisor same
On platform, same building information model is shared.Beneficial to project visualization, become more meticulous construction.
The content of the invention
The invention provides a kind of food stuff refrigerated storage large area overlength method for constructing terrace based on BIM, using computer aided manufacturing
Help design to realize the visualization and quantitative analysis of engineering construction, poured using subregion and avoid conventional the shortcomings that setting post-cast strip method, energy
Enough prevent concrete floor from producing crack, avoid Shi works Sew from influenceing heat preservation of refrigeration storage performance, and advantageously reduce additional process and contracting
Casual labourer's phase.
In order to achieve the above object, the present invention is realized using following technical scheme：
A kind of food stuff refrigerated storage large area overlength method for constructing terrace based on BIM, comprises the following steps：

It is re-closed after water；
2) concrete stirs；
A. various material usages are determined according to design mixture proportion, water content ratio of aggregate should often determine adjustment match ratio in time and use
Water；
B. loading sequence：Stone is first filled into mixer, cement is refilled, finally loads sand；When mixing additive, outside powdery
Agent is added to be previously charged into according to addition in inner wrapping, the used time adds simultaneously with thin coarse aggregate；Liquid additive presses usage amount and water
Load mixer stirring simultaneously；
C. mixing time：To make concrete stir, since whole mixs are fitted into mixing drum and play concrete
Untill discharging, the shortest time of concrete stirring is 90 seconds；
3) concrete transportation；
Must assure that concrete pump continuously works, and such as breaks down during pump concrete, idle hours more than 45 minutes or
There is segregation phenomenon in concrete, should be immediately with the concrete of residual in press water or other method flush pipe；
4) vibrate；
A. the drop height degree that freely inclines that concrete falls from discharging opening must not exceed 2 meters；
B. staged and layered is carried out continuously during casting concrete, and every layer pours height according to design feature, reinforcing bar density degree
