Description

A kind of In-situ cast concrete board

(1) technical field

The present invention relates to a kind of In-situ cast concrete board.

(2) background technology

The most of precast hollow slab that adopts of the building of brick mix structure and frame construction is as floor structure at present, this floor structure has advantages such as speed of application is fast, cost is low, but owing to firmly do not link between adjacent two precast hollow slabs, only use cement mortar blind, thereby not only globality is poor, be unfavorable for antidetonation, and phenomenons such as slit cracking, infiltration often occur, put to no little inconvenience and psychological pressure to resident family.In order to address the above problem, a lot of building have adopted the method for In-situ cast concrete board (hollow, solid), though In-situ cast concrete board has solved antidetonation and problems of crack, but when construction, to use a large amount of templates, like this, not only increase expense, and the speed of application that slowed down, prolonged the duration.The patent No. is ZL00203695.9's " combination concrete hidden rib floor structure " utility model patent, it is made up of prefabricated plate, formwork, dark rib, upper plate, each prefabricated plate is horizontal positioned at interval, on prefabricated plate, be fixed with formwork, formwork comprises upper plate and side plate on every side, be provided with dark rib between contiguous prefabricated thin plate or the formwork, upper plate covers on the formwork, and connect as one with dark rib, this kind floor structure no longer needs to use in a large number template, accelerate speed of application, shortened the duration, thereby reduced cost.But the vertical corner position of the shuttering member in this In-situ cast concrete board, the stressed complexity of In-situ cast concrete board, stress is more concentrated, easily produces crack even cracking destruction.Therefore, develop a kind of novel In-situ cast concrete board for being badly in need of.

(3) summary of the invention

The object of the present invention is to provide a kind of In-situ cast concrete board, characteristics such as have that mechanical property is good, stress is concentrated less, prevent the generation in crack, simple in structure, resistance to deformation, anti-shake performance are good, easy construction, speed of application are fast.

Solution of the present invention is on the basis of existing technology, comprise steel bar concrete, shuttering member, shuttering member comprises upper plate, sidewall on every side, upper plate, sidewall surrounds uncovered basin-shaped component on every side, the cast-in-situ reinforced concrete rib that sidewall forms for steel bar concrete each other around the shuttering member, the cast-in-situ reinforced concrete overlapping layers that forms for steel bar concrete on the upper plate of shuttering member, and link to each other with the cast-in-situ reinforced concrete rib, steel bar concrete and shuttering member are built up integral body each other, it is characterized in that described around at least one at least one vertical corner position of sidewall be vertical inner corner trim, Cast-in-place concrete has formed the Cast-in-place concrete reinforcing rib of cast-in-situ reinforced concrete rib intersection area at vertical inner corner trim position.Like this, in In-situ cast concrete board, because at the vertical corner position of shuttering member is vertical inner corner trim, formed the reinforcing rib of cast-in-situ reinforced concrete rib at the inner corner trim position, thereby can eliminate the stress concentration phenomenon of In-situ cast concrete board effectively, prevent the generation in crack, and can bear bigger point load effect and do not destroy; If shuttering member is close to arrangement, at vertical inner corner trim position, Cast-in-place concrete has then formed the shearing pier or the post of In-situ cast concrete board, significantly reduced the consumption of steel bar concrete, alleviate the weight of In-situ cast concrete board, improved the anti-seismic performance of In-situ cast concrete board, improved the mechanical property of In-situ cast concrete board; Simultaneously, simple in structure, characteristics such as intensity is high, resistance to deformation, the anti-vibration performance is good, construction is easy, convenience, speed of application is fast, construction cost is low that In-situ cast concrete board also has, 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 cast-in-situ reinforced concrete or prestressed reinforced concrete are used, and are particularly useful for hollow arch without beam and use.

Another solution of the present invention is on the basis of existing technology, comprise steel bar concrete, shuttering member, prefabricated plate, shuttering member comprises upper plate, sidewall on every side, upper plate, sidewall surrounds uncovered basin-shaped component on every side, shuttering member is arranged on the prefabricated plate, the bottom surface of prefabricated plate flushes with the bottom surface of In-situ cast concrete board, the cast-in-situ reinforced concrete rib that forms for cast-in-situ reinforced concrete between the sidewall around the shuttering member, it on the upper plate of shuttering member the cast-in-situ reinforced concrete overlapping layers, and link to each other with the cast-in-situ reinforced concrete rib, steel bar concrete, shuttering member and prefabricated plate are built up integral body each other, it is characterized in that described around at least one at least one vertical corner position of sidewall be vertical inner corner trim, Cast-in-place concrete has formed the Cast-in-place concrete reinforcing rib of cast-in-situ reinforced concrete rib intersection area at vertical inner corner trim position.Like this, in In-situ cast concrete board, because at the vertical corner position of shuttering member is vertical inner corner trim, formed the reinforcing rib of cast-in-situ reinforced concrete rib at the inner corner trim position, thereby can eliminate the stress concentration phenomenon of In-situ cast concrete board effectively, prevent the generation in crack, and can bear bigger point load effect and do not destroy; If shuttering member is close to arrangement, at vertical inner corner trim position, Cast-in-place concrete has then formed the shearing pier or the post of In-situ cast concrete board, significantly reduced the consumption of steel bar concrete, alleviate the weight of In-situ cast concrete board, improved the anti-seismic performance of In-situ cast concrete board, improved the mechanical property of In-situ cast concrete board; Simultaneously, simple in structure, characteristics such as intensity is high, resistance to deformation, the anti-vibration performance is good, construction is easy, convenience, speed of application is fast, construction cost is low that In-situ cast concrete board also has, 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 cast-in-situ reinforced concrete or prestressed reinforced concrete are used, and are particularly useful for hollow arch without beam and use.
