Description
Technical field
The invention belongs to building field, be specifically related to a kind of arch without beam noggin piece, its preparation method and application.
Background technology
Along with improving constantly of socioeconomic development and living standards of the people, house architectural structure is also constantly changing, the requirement of people to large space, large span floor space is more and more higher, so the flat slab structure technology increasing space is arisen at the historic moment.At first, it is the arch without beam of representative that people have developed with nine-squares beam structure, but because nine-squares beam structure is not from the object truly reached without beam, simultaneously, there is the diseconomy on the complexity larger than conventional structure and material in nine-squares beam structure, therefore fail to popularize application in an all-round way in construction.Afterwards, in succession occur being that the cavity of material is filled mould, is that the concrete cavity of material is filled mould and is that the cavity of material fills mould with composite fibre with cement with gypsum, fill moulds for these three kinds effectively to solve arch without beam and need the inserts problem of thicker large panel structure, then reach and cancel nine-squares beam, hidden girder thus reach the effect of chainless drives.But the filling mould of these three kinds of materials also degree different there are the following problems:
With gypsum be the cavity of material fill mould and with cement be that the concrete cavity mould of material has that weight is large, cracky and greatly increase the shortcoming of floor deadweight, be that the cavity of material is filled mould and solved the large problem of material weight with composite fibre, but also have that self bearing capacity is poor, cracky and large three outstanding problems of anti-floating difficulty.
Summary of the invention
In order to solve the problems referred to above that prior art exists, the invention provides a kind of arch without beam noggin piece.While the deadweight that significantly can reduce described arch without beam noggin piece, the intensity of described arch without beam noggin piece can be improved, to meet the needs of building operations.
The technical solution adopted in the present invention is: a kind of arch without beam noggin piece, comprises member bodies, cement layer and scrim layer, and the shape of described member bodies is cuboid, and the edge of the bottom surface of described member bodies is provided with chamfering; Described cement layer and scrim layer cover in described member bodies from inside to outside successively.
Described member bodies adopts light material to make, and while significantly can reducing the deadweight of described arch without beam noggin piece, cement layer and scrim layer can improve the intensity of described arch without beam noggin piece, to reach the needs of building operations.Meanwhile, be provided with chamfering at the edge of the bottom surface of described member bodies, form the passage circulated for concrete between the soffit formwork of described chamfering and described arch without beam noggin piece, be convenient to concrete perfusion.
