Abstract
The reinforced concrete prefabricated slab includes one slab, and features that the slab has steps in the upper or the lower peripheral planes. 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 upper face of plate surrounding or with lower face step is arranged.Like this, when step being arranged when the upper face of plate surrounding or with lower face, when described precast plate is applied in the In-situ cast concrete board, edges of boards have step to be mounted in precast plate in the Cast-in-place concrete fully, make its joint interface the crack can not occur, can fully guarantee the quality of In-situ cast concrete board, thereby reached purpose of the present invention, the hollow building cover, roof system, body of wall, sole plate and the hollow bridges that are applicable to various cast-in-situ reinforced concretes or prestressed reinforced concrete are used, and are particularly useful for hollow arch without beam and use.
Feature of the present invention is also that described end wall is fluted, at least a in the pit, projection, raised line.Like this, during at least a in, pit fluted, projection, the raised line when end wall, after described precast plate is applied in the In-situ cast concrete board, said structure structure on the end wall forms corresponding mutual riveted with Cast-in-place concrete, make its cast-in-place and prefabricated joint interface can cracking destruction, fully guaranteed the quality of In-situ cast concrete board.
Feature of the present invention is that also described step is a two stage steps.Like this, when step was two stage steps, when described precast plate was applied in the In-situ cast concrete board, edges of boards had step precast plate can be mounted in the Cast-in-place concrete fully, make its joint interface the crack can not occur, can fully guarantee the quality of In-situ cast concrete board.
Feature of the present invention is that also four corners of described plate are set to inner corner trim.Like this, when four corners of plate were set to inner corner trim, after described precast plate was applied to In-situ cast concrete board, Cast-in-place concrete poured in the inner corner trim, and precast plate firmly is mounted in the Cast-in-place concrete, made its joint interface can not produce the crack, had fully guaranteed the quality of In-situ cast concrete board.
Feature of the present invention is that also described step is provided with net template.Like this, when step is provided with net template, after described precast plate is applied in the floor, net template combines with Cast-in-place concrete, with precast plate and Cast-in-place concrete firmly drawknot become whole, make the damage not easy to crack of its combination interface, increased substantially the pouring quality of floor.
Feature of the present invention is that also described step is provided with tenon or mortise.Like this, when step was provided with tenon or mortise, described precast plate was applied in the In-situ cast concrete board, tenon or mortise are with after Cast-in-place concrete combines, increase substantially the adhesion stress between precast plate and the Cast-in-place concrete, made its bond area bigger, guaranteed the quality of In-situ cast concrete board.
Feature of the present invention is that also described step is provided with mechanical keys.Like this, when step was provided with mechanical keys, described precast plate was applied in the In-situ cast concrete board, and tenon or mortise have increased substantially the adhesion stress between precast plate and the Cast-in-place concrete with after Cast-in-place concrete combines, and make its bond area bigger, have guaranteed the quality of In-situ cast concrete board.
Feature of the present invention is that also vertical interval is arranged on the described step.Like this, when on the step vertical interval being arranged, when described precast plate was applied in the In-situ cast concrete board, edges of boards had step precast plate can be mounted in the Cast-in-place concrete fully, make its joint interface the crack can not occur, can fully guarantee the quality of In-situ cast concrete board.
Feature of the present invention is that also described net template is level or vertical the layout.Like this, when net template be level or when vertically arranging, after described precast plate was applied in the Cast-in-place concrete floor, the cast-in-place and prefabricated boundary strength of risking one's life that engages was big, makes it be difficult for producing the crack, has guaranteed the quality of floor.
Feature of the present invention is that also described plate is provided with the reinforcing bar that exposes.Like this, when plate was provided with the reinforcing bar that exposes, after described precast plate was applied in the Cast-in-place concrete floor, reinforcing bar combined with Cast-in-place concrete, made precast plate and cast-in-situ concrete structure form the integral body of load power transmission jointly, made the precast plate can the participation structure power transmission.
Feature of the present invention is that also described plate is provided with at least a in stiffener, bracing boom, rope, vertical rib, the cross rib.Like this, when plate is provided with stiffener, when stiffener was at least a in stiffener, bracing boom, rope, vertical rib or the cross rib, the strength and stiffness of precast plate were all strengthened significantly, make precast plate be difficult for deformed damaged, but and participation structure load.
Feature of the present invention is that also described plate is provided with the connector that is connected with other member.Like this, when plate is provided with other member is connected connector, when described precast plate was applied in the In-situ cast concrete board, connector can be connected with other structure unit construction very easily, has made things convenient for to practice.
Feature of the present invention is that also described plate periphery has anti-limit of peviform or peviform raised line.Like this, when the plate periphery has anti-limit of peviform or peviform raised line, behind this two of the precast plates or polylith amalgamation that has anti-limit or a peviform raised line, can form hollow box, be applied in the In-situ cast concrete board after, can form hollowcore slab, reduce the consumption of concrete, reduce cost, improve weight bearing power.
