Description
Technical field
The present invention relates to a kind of corrugated sheet steel-concrete combined structure and its computer controls forming method, the structure
System is applied in the middle of the wall limb structure in Multistory-tall building, belongs to building structure technology field.
Background technology
(1), the application of wall limb structure
Wall limb structure is a kind of shear wall structure system, is widely used in Multistory-tall building, especially in residential structure body
In system, the flexibility of the house type arrangement that it brings is favored by architect deeply, can avoid going out using frame structure in residential housing
The head beam dew post phenomenon that existing beam column is inconsistent with width of wall body and brings, it is also possible to overcome bean column node to be exposed to the interior space
And influence to use the problem with perception.Especially, it is to avoid support is set in steel-frame structure to opening up door and window hole and filling wall
The difficulty that construction brings.Therefore, the innovation and development to wall limb structure is filled to promoting housing industrialization, building industrialization and building
It is significant with changing.
(2), the development of wall limb structure
Concrete wall limb structure is applied to multilayer and high building structure earliest, and current this structural shape also extensively should
With, but because concrete in tension intensity is relatively low, easily ftractureed under outer load action, cause concrete wall limb structure ductility compared with
Difference.Meanwhile, there is situ wet operation and pour, it is necessary to template support in concrete, working measure is costly, does not also meet industrialization
Production and the developing direction of assembling building.Therefore, people are sought for new high-performance wall limb structural shape.
Steel plate and concrete composite wall limb structure grows up after concrete wall limb structure, more using plain plate
Parcel concrete or concrete parcel two kinds of situations of steel plate.For the combining structure that plain plate wraps up concrete, be in steel plate
Inner side sets peg to ensure concrete and the co-ordination of both steel plates.But, the effect of contraction of the two is less desirable, coagulation
The effect of contraction to steel plate can be lost after soil cracking or destruction, plain plate also can lose bearing capacity quickly because constraint is lost,
Therefore overall wall limb also can lose bearing capacity and ductility.Construction aspect, in concreting process, outside plate is in itself
The pouring thrust of concrete generation can not possibly be resisted, thus must be provided with additional supporting structure to ensure steel plate in casting process
Stability.The wall limb structure of concrete parcel steel plate has in Tall Building Hybrid Structure as the built-in steel plate of Core Walls Structure extensively should
With the bearing capacity and ductility of Core Walls Structure can be effectively improved.But the interaction of the two is performed poor, such as when outside concrete exists
After the lower cracking of external force effect is broken, abandoned steel plate also can quickly lose stability.Mould is set in concreting
Plate, working measure is complicated and time-consuming, therefore, at present using few in wall limb structure.
In recent years, another type steel-concrete wall limb structure has obtained significant progress, using a series of hot-rolling H-shaped
The interior mode for filling concrete is constituted after steel or U-steel or L-shaped steel Combination Welding.Although the wall limb structure of this type is conducive to
Industrialized production, but welding capacity is larger, not only increases construction cost and construction period, and structure remnants after welding
Stress and residual deformation outstanding problem.Importantly, the material of the weld seam of welding formation and heat affected area becomes fragile so that tying
Structure is easy to produce brittle fracture under reciprocating load, and especially in cold district, this problem is protruded very much.
(3), corrugated sheet steel briquetting process and computer-aided control technology
The corrugated sheet steel applied in architectural engineering has various patterns, and the roofing and metope for being mainly used in industrial premises are gone along with sb. to guard him
Structure, the cold-rolled steel sheet for being not more than 1.5mm using thickness makes.Roller being used the current briquetting process to this kind of sheet metal more
Mode is rolled, multigroup roller progressively profile and size of the roll forming to design requirement is set.For applying the ripple in wall limb structure
Shape steel plate, its thickness is general, and now steel plate will undertake larger load between 4mm-30mm, such as still use above-mentioned multigroup roller
Progressively briquetting process then needs special large-tonnage and powerful roller to prick equipment, while will also substantially reduce compressing effect
Rate, so that seeking new briquetting process and control technology.
For the corrugated sheet steel used for wall limb structure, its compacting includes compacting, the ripple of corrugated sheet steel with assembling process
The assembling positioning of shape steel plate, bolt penetration hole, bolt are tightened, side column is welded and the operation such as end seal plate welding, there is presently no seeing
Realized on full-automatic production line by using computer-aided control forming technique to this process.
