Description
The application for the applying date be that December 9, application number in 2003 are 200310121941.2, name is called the dividing an application of application for a patent for invention of " a kind of cavity form component for concrete filling ".
(1) technical field
The present invention relates to a kind of cavity form component for concrete filling.
(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 inconvenience, production efficiency is low, is not easy to streamline production, corresponding cost height, thereby, develop a kind of novel cavity form component for concrete filling for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of cavity form component for concrete filling, have the characteristics such as easy, that production efficiency is high, cost is low of making.
Solution of the present invention is on the basis of existing technology, comprise upper plate, sidewall on every side, upper plate, sidewall surrounds the open cavity formwork on every side, it is characterized in that described hollow mould shell all is put together by precast segment, precast segment is at least five precast slabs, comprise sidewall around a slice upper plate, four, prefabricated bracing boom is arranged, put more energy into floor or rope in the cavity.Like this, because hollow mould shell all is put together by precast segment, each precast segment can be made in advance, thereby the making of cavity former component is easy, cost is low; Simultaneously, cavity former component also can be put together by each precast segment at the construction field (site), constructs, carries more convenient; In addition, characteristics such as that cavity former component also has is simple in structure, resistance to deformation, the anti-vibration performance is good, speed of application is fast, 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.
