Description
(1) technical field
The utility model relates to a kind of laminated floor slabs.
(2) background technique
Currently, the floor of multilayer or skyscraper mainly uses Cast-in-place concrete one-piece casting, general construction method is to apply
Defined interim scaffold is set up at work scene, and sets template, then configuration reinforcement as needed, and it is mixed then to carry out scene
Solidifying soil pours.In advance in plant-manufactured so-called prefabricated template, then what it is instead of the template construction in this scene is
This prefabricated template is moved in into scene, is mounted on corresponding scaffold and constructs, since its workability is advanced, work can be shortened
Phase, so being widely adopted in recent years.So being widely adopted in recent years.The template of this kind of pre-production has profiled sheet, concrete
Template and pre-stress concrete template etc., still, this kind of prefabricated template is in the In-situ cast concrete boards construction application mistake such as Cast-in-place Concrete Building Floor, roof system
There is also some problems in journey, and if cost is excessively high, weight is too big, not light enough.For example, by using profiled sheet as not removing
When permanent formwork, although intensity is high, rigidity is big, at high cost, meanwhile, exposed steel form is easy corrosion, seriously affects
The beauty of building and use.When using concrete form as the permanent formwork that do not remove, such as Patent No. 03227765.2, name
The referred to as utility model patent of " a kind of floor spiced by steel reinforced concrete ", in the patent specification the 13rd row of page 3 to the 22nd
The implementation of the utility model has been described in detail in row, " floor spiced by steel reinforced concrete, including the prefabricated structure of armored concrete
Part, reinforcing bar, floor are assemblied to form by muti-piece precast member for reinforcing bar concrete, the two sides under precast member for reinforcing bar concrete longitudinal rib
It is provided with hole, reinforcing bar passes through the hole of component two sides, connects muti-piece precast member for reinforcing bar concrete, after floor spiced, in slot again
Casting concrete is filled and led up.", in the utility model patent scheme, floor is assemblied to form by muti-piece precast member for reinforcing bar concrete, and
By now wearing reinforcing bar and the existing reinforcing bar of precast member for reinforcing bar concrete forms criss-cross layout and forms bi-directional configuration, no
Live formwork is needed, reinforcing bar is now worn and the original reinforcing bar of precast member for reinforcing bar concrete forms criss-cross layout, can bear two-way
Load itself is still check configuration, now need to wear reinforcing bar and can bear bidirectional load, moreover, its component longitudinal rib formations is made
It at lateral partition, is not easy to pipeline and wears, the shear resistance at the overlapping interface between Cast-in-place concrete and template is low, superstructure or roof system
The material consumptions such as working reinforcing bar, concrete are big, at high cost, globality poor.The utility model in view of the above technology do by disadvantage
It improves.
(3) utility model content
The purpose of this utility model is to provide a kind of laminated floor slab, this base plate strength is high, rigidity is big, is being applied to
It can be used directly as end template when in floor, not need other formwork, not only reduce template, while template can be reduced
Bracket does not have to falsework, does not need demoulding, has saved duration and cost；Instantly environmentally protective, energy conservation is also complied with simultaneously
The requirement of emission reduction, greatly reduced building waste.
The solution of the utility model is including precast truss frame bar shaped bottom plate on the basis of existing technology, cast-in-place steel

Utility model is one longitudiual truss of setting near a longitudinal edge of truss bar shaped bottom plate, rather than it is traditional be symmetrical arranged,
The bar shaped bottom plate has strong flexibility, can make and be adaptively adjusted for the floor of different structure.The two of truss bar shaped bottom plate
End can overlap on the wall or on beam, due to the effect of truss, can give full play to the mechanical property of truss, reduce In-situ cast concrete board
The dosage of reinforcing bar is thinned the thickness of In-situ cast concrete board, reduces cost, and be greatly improved mutual embedding between Cast-in-place concrete and rack
Gu effect improves the shear resistance at the overlapping interface between Cast-in-place concrete and template, the overall performance of superstructure is improved, in addition, truss
Bar shaped bottom plate can be realized in factory to be produced in enormous quantities, is advantageously reduced production cost and construction cost, is suitable for various cast-in-place steel
The cored slab of muscle concrete or prestressed reinforced concrete, solid superstructure, roof system use.
The utility model is further characterized in that the material of the stretching expanded metal lath is low carbon steel plate, aluminium sheet, stainless steel plate
Or titanium plate.
The utility model be further characterized in that the stretching expanded metal lath with a thickness of 0.3-8.0mm.
The utility model is further characterized in that the longitudinal middle point of the bar shaped bottom plate is provided with reinforcing mat, and reinforces
Net is arranged below longitudinal prestressing reinforcing bar；Reinforcing mat is steel mesh or web.Generally at carrying or in application, bar shaped bottom
It is weak part in the middle part of plate, by the setting of reinforcing mat, the intensity at the position can be reinforced, while in certain field of load
It is interior, the thickness of bar shaped bottom plate can be thinned.
The utility model is further characterized in that the base plate thickness is greater than 5 centimetres.
The utility model is further characterized in that the top boom of the truss is steel pipe.
The utility model is further characterized in that pour in the steel pipe and set in cast-in-place concrete or the steel pipe
