Description

In-situ cast concrete board
One technical field
The present invention relates to In-situ cast concrete board.
Two background technologies
At present, a lot of building have adopted the method for hollow cast slab.The Cast-in-place concrete floor can solve antidetonation and problems of crack, but will use a large amount of templates when construction, like this, has not only increased expense, and the speed of application that slowed down, and has prolonged the duration.The patent No. is ZL00203695.9's " combination concrete hidden rib In-situ cast concrete board plate " utility model patent, it is by prefabricated plate, formwork, dark rib, upper plate is formed, 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, and for example the application number of applicant oneself application is 03142878.9 application for a patent for invention, no longer needs to use template in a large number when adopting this kind structure manufacture floor, has accelerated speed of application, shorten the duration, thereby reduced cost.But when this In-situ cast concrete board plate was constructed, topmost problem was that this formwork is used for the effect that the Cast-in-place concrete floor only plays the formation cavity, and itself can't use as the structure-bearing member, therefore, developed a kind of new In-situ cast concrete board for being badly in need of.
Three summary of the invention
The object of the present invention is to provide a kind of In-situ cast concrete board, when this In-situ cast concrete board is constructed, can save template in a large number, even do not need template, and have from heavy and light with respect to the traditional structure In-situ cast concrete board, low cost and other advantages, most critical be that this In-situ cast concrete board can form the latent beam rib structure In-situ cast concrete board of superposed type that Cast-in-place concrete and prefabricated units combine, the bright beam that the lower shoe of In-situ cast concrete board is not outstanding, need to be specially adapted in the clear and definite building of high load of large span and primary and secondary load-carrying construction, simultaneously, the top board of prefabricated units can be used as the top board of floor slab structure, do not need Cast-in-place concrete on prefabricated units again, reduced difficulty of construction significantly, rib then only needs to build the latent beam of Cast-in-place concrete or/and can form in-situ deposited prefabricated structural beams rib In-situ cast concrete board, greatly improve the load performance of In-situ cast concrete board, can reduce the characteristics of In-situ cast concrete board construction cost significantly.
