The defect that integrated synthesis utilizes.
There is a kind of netted box component in related art, uses the netted box-shaped structure of combined type of mesh shape shell
Part substitutes the hermetically sealed hollow cavity component of the prior art or the solid Cavity structural member of polystyrene foam, overcomes existing hollow floor non-
Defect existing for core-drawing pore-creating Cavity structural member.But this netted box component of combined type is as cast-in-situ hollow building roof
When filler, since member exterior shell is metal grill, penetrated by mesh so having the concrete mortar poured
In netted combination Cavity structural member, the filling effect of component is reduced, the waste of concrete material is also resulted in construction, in addition
The pressure of construction loads and top flange concrete is still suffered from a particular application, it is necessary to making a large amount of support and port in case
Closure, supporter is made using steel pipe and needs internal a large amount of structures combination, the envelope using similar steel Web materials as port
When stifled, binding site needs a large amount of welding, combination difficulty larger.
Based on the problems of the above-mentioned prior art, the utility model patent of the applicant's earlier application
It is a kind of for the built-in netted box-shaped cavity structure of special type closing in filled of cast-in-situ hollow building roof involved in CN201620167454.2
Part realizes cast-in-situ hollow building roof hole creating technology using close up netted box component of the special type, changes steel lattice shape and does not allow coagulation
Soil sand slurry penetrates into steel mesh, does not generate buoyancy, good with concrete blending, overcomes defect existing for existing hollow floor technology.So
And this extraordinary high ribbed formwork is in the production process, using constriction plate preparation method so that consuming plank amount is big, so that the special type
Close up netted box-shaped Cavity structural member manufacturing cost increase.
There are above many defects in view of the preset component of filling in the prior art, therefore, developing one kind having existing skill
The comprehensive function feature of art makes hollow floor implement the good built-in noggin piece of overall performance, can make full use of coagulation
Native surface tension changes steel latticed structures and concrete mortar is not allowed to penetrate into steel mesh, enhancing structure carrying good with concrete blending
Ability bears the normal pressure of the construction loads and top flange concrete on frame top, realizes the industrialized production of netted box-type member, gram
Taking the prior art, there are a large amount of supports and frameworks inside framework to block trouble, defect of high cost, and it is existing to break through cast-in-situ hollow building roof
There is technology, has become the technical issues of cast-in-situ hollow building roof technical field is badly in need of solving.
Steel construction strategy is carried out in view of country at this stage simultaneously and carries out assembled architecture, lay foundation for housing industrialization,
No matter how to extend and update from the connotation and extension of building, it is all related with architectural structure system；Using multi-functional, economy,
Scientific and technological content, energy conservation and environmental protection and the market demand is big, safety coefficient is high, and meet building for national industrial policies and industrial development direction
Building structure system.Therefore, on the basis of the existing background technology of applicant, the prior art is subjected to perfect, upgrading, integrated application is arrived
In housing industrialization, by cast-in-place cavity building roof Technology Difficulties problem factory industry neutralizing determine, shape, lattice of establish rules, surely assembly position,
Prefabricated member is quantitatively produced, the mode that structure is integrally forced through cast-in-place concrete is handled, and industrialized production is prefabricated
Assembled Cavity structural member combines with cast-in-site armored concrete.Therefore, it develops a kind of comprehensive with the prior art
The good central island force type cavity building roof assembled cavity floor of the overall performance of functional characteristics is closed, making can inside cavity building roof
Good with concrete blending to make full use of concrete surface tension, enhancing structure bearing capacity, bottom hanging ability is strong, real
Existing industrialized production, is the great breakthrough for realizing prefabricated assembled frame-shear-wall structure system new technology, has become dress
Urgent need with the innovation of formula technical field of buildings.
Invention content
The purpose of this utility model is that assembled architecture process is promoted, a kind of central island force type cavity building roof assembly
Formula cavity floor improves available frame shear wall structure system and frame core wall structure system；Make full use of factory industry
Advantage, the problems such as producing assembled cavity floor, solve construction, environmental protection, matter weight, cost, work efficiency existing for existing system；It builds
The mode that building structure is integrally forced through cast-in-site armored concrete solves, industrialized production cavity prefabricated components and scene
Casting reinforced concrete combines, and reaches optimization available frame shear wall structure system technology, to existing assembled frame
Frame shear wall structure system system carries out transition and upgrade, updates.

Six row steel plates expansion mesh 203 is set between shape reinforcing rib 201, and respectively there is the expansion of three row steel plates on 204 both sides of steering connection strap
Mesh 203, the direction for being located at the three row steel plates expansion mesh for turning to 204 side of connection strap is identical, and is connected positioned at the steering
The steel plate on both sides expands mesh 203 not in same direction, that is, forms " people " of the axis centered on turning to connection strap 204
Character form structure.
Continuous V-type reinforcing rib 201 arranged in parallel is the main source of intensity in the steel plate expansion web.Steel mesh face 202
It is upper to expand mesh 203 with neat steel plate, there is the work(for reinforcing the combination between steel plate expansion web and the concrete material of cast
Energy.
The direction of expansion web existing in the prior art, adjacent two row steel plate expansion mesh is different, easily causes pouring
When concrete penetrate into babinet.And steel plate expansion web provided by the present application, wherein adjacent three row steel plates expansion mesh
Direction is identical, avoids when pouring girt strip concrete, the refluence of babinet side concrete, turns to connection strap side and is set as same
Mesh direction make the combination of concrete and mesh more preferable, the fluency poured is more preferable, considerably reduces into babinet
Interior amount of concrete reduces loss.
Figure 13-15 shows respectively steel plate expansion web used by the steel plate expansion net cage Cavity structural member of the utility model
