Disclosed is a hollow concrete shuttering member for concrete filling, which comprises an upper board (1), and peripheral side panels (2), wherein the upper board (1), the peripheral side panels (2) enclose open hollow shuttering members, characterized in that at least two of the hollow shuttering members are pasted from prefabricated panels (3), forming open chambers or closed chambers, the prefabricated panels (3) are connected into an integrality through a connecting member (4). the upper board prefabricated panels (3) and / or the lower board prefabricated panels (3) cover the central hollow frame which is formed from L-shaped or U-shaped or I-shaped prefabricated panels through assembly, the upper board or / and the lower board are provided with projected reinforcement articles (7) on the end surfaces. The invention can be applied to cast-in-situ reinforced concrete or prestressed reinforcement concrete's hollow storied-building roofings, house roofings, walls, foundation bedplates and hollow bridges, especially for hollow flat slabs.
Description
[0001] This application is a divisional application of an invention patent application with a filing date of December 9, 2003, an application number of 200310121937.6, and a title of “A Cavity Formwork Member for Concrete Filling”. (1) Technical field [0002] The invention relates to a cavity formwork component for concrete filling. (2) Background technology [0003] At present, most of the buildings with brick-concrete structure and frame structure use prefabricated hollow-core slabs as floor slabs. This kind of floor slab has the advantages of fast construction speed and low cost, but because there is no firm connection between two adjacent prefabricated hollow-core slabs , Only cement mortar is used to fill the gaps, so not only the integrity is poor, which is not conducive to earthquake resistance, but also cracks and water seepage often occur in the gaps, causing great inconvenience and psychological pressure to the residents. In order to solve the above problems, many...
