Description

A kind of cast-in-place concrete cored

The application for the applying date be that June 6, application number in 2005 are 200510074457.8, name is called the dividing an application of application for a patent for invention of " a kind of cast-in-place concrete cored ".

(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 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).Though the Cast-in-place concrete floor has solved antidetonation and problems of crack, when construction, to use a large amount of templates, like this, not only increased 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 when the shuttering member in this floor structure is produced, make inconvenient, production efficiency is low, be not easy to streamline production, particularly in transportation and work progress, the formwork transportation is extremely inconvenient, whole shuttering member takies a large amount of transport spaces, wasted a large amount of transport resources, increased cost of transportation, and formwork easily causes damage because of the extrusion and collision that jolts in transportation, the breakage rate height, corresponding cast-in-place concrete cored construction cost height, thereby, develop a kind of novel cast-in-place concrete cored for being badly in need of.

(3) summary of the invention
