Abstract
The reinforced concrete prefabricated slab includes one slab, and features that the slab has mechanical tenons formed with the formwork holes of the demolded grid formwork in the ends and side walls. The present invention is suitable for in-situ cast or pre-stressed reinforced concrete hollow floor slab, roof, wall, foundation slab and hollow bridge, especially hollow flat floor slab.
Description
(1) technical field
The present invention relates to a kind of steel bar concrete precast plate.
(2) background technology
At present, shuttering member is generally by upper plate, side plate and base plate surround the formation Cavity structural member, the upper plate of shuttering member, the side plate and the various connected modes of employing of going to the bottom form whole shuttering member, perhaps when producing, adopt integral forming technique to make whole shuttering member, such shuttering member overall tightness is good, in light weight, be easy to whole supporting transportation and construction, the Cast-in-place concrete that does not bear structural capacity in the cast-in-situ concrete hollow structure can be emptied, form hollow concrete structure, reduce the deadweight of cast-in-situ concrete structure effectively, reduced the consumption of material, reduced cost, but, this shuttering member is in transportation, pile up and the construction application process in, its base plate damages easily, can not bear big working load, the part withstands shocks a little less than the damage capability, destroy easily and Cast-in-place concrete is entered in the member, thereby influence structural performance, and, whole shuttering member application flexibility is relatively poor, therefore the model size of malleable shuttering member, does not develop a kind of novel steel bar concrete precast plate for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of steel bar concrete precast plate, have simple in structure, convenient transportation, cost of transportation is low, take that work plane is little, assembly unit is convenient, intensity is high, rigidity greatly, characteristics such as cracky not.
Solution of the present invention is on the basis of existing technology, comprises plate, it is characterized in that the mechanical type tenon that the distolateral wall of plate periphery has net template form removal rear pattern plate mesh to make.Like this, when the distolateral wall of plate periphery has the mechanical type tenon that net template form removal rear pattern plate mesh makes, after described precast plate is applied in the In-situ cast concrete board, the mechanical type tenon can embed in the Cast-in-place concrete, combine with Cast-in-place concrete, can be with precast plate build-in firmly, be difficult for loosening, but also the precast plate that can shrinkage pool or tenon cover be arranged with opposite position mutually amalgamation form integral mold plate, can prevent the generation in crack effectively, thereby reached purpose of the present invention, be applicable to the hollow building cover of various cast-in-situ reinforced concretes or prestressed reinforced concrete, roof system, body of wall, sole plate and hollow bridges are used, and are particularly useful for hollow arch without beam and use.
