Description
(1) technical field
The present invention relates to a kind of cast-in-place concrete cored.
(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 Cast-in-place concrete floor (hollow, solid).When construction, to use a large amount of templates though the Cast-in-place concrete floor has solved antidetonation and problems of crack, like this, not only increase expense, and the speed of application that slowed down, the duration prolonged.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 lower shoe of this floor structure is a prefabricated plate, has the amalgamation seam each other, globality is poor, if lower shoe adopts the cast-in-situ reinforced concrete plate, though good integrity, the problem that does not have the amalgamation seam, but construction is inconvenient, the Cast-in-place concrete leakiness, be prone to problems such as voids and pits, simultaneously, when this shuttering member is produced, make inconvenience, production efficiency is low, is not easy to streamline production, therefore corresponding cost height, is developed a kind of novel cast-in-place concrete cored for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of cast-in-place concrete coredly, have good overall performance, and easy construction, construction cost is low, construction quality good.
Solution of the present invention is on the basis of existing technology, comprise steel bar concrete, shuttering member, shuttering member is wrapped up in and is contained in the steel bar concrete, shuttering member alternately, be the cast-in-situ reinforced concrete rib each other, it on it cast-in-situ reinforced concrete upper plate, it is the cast-in-situ reinforced concrete lower plate down, shuttering member comprises upper plate, sidewall on every side, upper plate, sidewall surrounds uncovered basin-shaped component on every side, the upper plate middle part that it is characterized in that described basin-shaped component has a skylight, and there are at least one transverse reinforcement or the cable wire that pass the skylight in the skylight.Like this, when the upper plate middle part has a skylight, when there are at least one transverse reinforcement that passes the skylight or cable wire in the skylight, cast-in-place concrete cored building in the process, thereby the cast-in-situ reinforced concrete lower plate that can pour into a mould down under the Cast-in-place concrete formation shuttering member to shuttering member from the skylight is constructed more convenient, and guaranteed the pouring quality of cast-in-situ reinforced concrete lower plate, make it not be prone to voids and pits, after having watered the cast-in-situ reinforced concrete lower plate, the skylight is covered, build the Cast-in-place concrete between the shuttering member and top again, thereby guaranteed cast-in-place concrete cored pouring quality, can not reduce cast-in-place concrete cored hollow rate, help reducing construction cost, thereby reached purpose of the present invention, be applicable to the hollow building cover of cast-in-situ reinforced concrete 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.
The present invention also is do not have the cast in place reinforced bar upper plate, the upper surface of upper plate and cast-in-place concrete cored upper surface flush on the upper plate of described shuttering member.Like this, when not having the cast in place reinforced bar upper plate on the upper plate of shuttering member, make the cast-in-place concrete cored open two way ribbed slab in top that formed, whole compressive strength is good, has improved cast-in-place concrete cored supporting capacity.
The present invention is that also the bottom of described shuttering member does not have the cast-in-situ reinforced concrete lower plate.Like this, when the bottom of shuttering member does not have the cast-in-situ reinforced concrete lower plate, make the cast-in-place concrete cored open two way ribbed slab in bottom that formed, whole compressive strength is good, has improved cast-in-place concrete cored supporting capacity.
The present invention also is do not have the cast in place reinforced bar upper plate on the upper plate of described shuttering member, the upper surface of upper plate and cast-in-place concrete cored upper surface flush, and the bottom of shuttering member does not have the cast-in-situ reinforced concrete lower plate.Like this, when the upper plate of shuttering member on do not have the cast in place reinforced bar upper plate, the upper surface of upper plate and cast-in-place concrete cored upper surface flush, when the bottom of shuttering member does not have the cast-in-situ reinforced concrete lower plate, the cast-in-place concrete cored in-situ deposited prefabricated superimposed sheet of two-way rib structure that formed, reduce the consumption of Cast-in-place concrete significantly, reduced cast-in-place concrete cored deadweight, improved cast-in-place concrete cored supporting capacity.
