Abstract
The invention discloses a pin type plaster mould shell and concrete combined dense rib flat slab and a manufacturing method thereof. The manufacturing method comprises the following steps of firstly, preparing a plaster hollow cavity mould shell by using industrial waste plaster or ardealite; pre-embedding a shearing force connecting pin on the plaster hollow cavity mould shell; arraying the plaster hollow cavity mould shell on a pouring supporting bottom plate of a pouring floor system; then carrying out concrete pouring on the plaster hollow cavity mould shell; and after concrete is condensed, removing the pouring supporting bottom plate, so as to obtain the integrated pin type plaster mould shell and concrete combined dense rib flat slab which is formed by connecting the shearing force connecting pin with the plaster hollow cavity mould shell which is used as a permanent formwork, a dense rib and a floor cover plate. The pin type plaster mould shell and concrete combined dense rib flat slab and the manufacturing method thereof not only have the advantages of higher structural strength, fewer used steel products and cement materials and lighter weight, but also have the advantages of small structural height, less occupied space, convenience for construction, and capability of efficiently utilizing a lot of the industrial waste plaster or the ardealite as building materials.
Description
Technical field
The present invention relates to a kind of pin formula gypsum formwork and the close rib arch without beam of Combined concrete and preparation method thereof, belong to building superstructure manufacture technology field.
Background technology
The use function of building relies on building cover structure to realize fully, relative vertical structure (post, wall), the area of building cover structure is huge, again owing to its several, tens of inferior reusing, so the material that building cover structure consumes, resource, manpower etc. account for the major part of whole building structure.At present, superstructure in the prior art adopts the superstructure of beam and slab type structure mostly, the superstructure of traditional beam and slab type structure mainly exists many, the shortcoming such as large that takes up room of the material usages such as Heavy Weight, steel and cement, and traditional superstructure preparation method can't effectively utilize industrial waste gypsum or ardealite to use as constructional materials.Therefore, existing building cover structure and preparation method or not ideal enough.
Summary of the invention
The objective of the invention is: provide a kind of structural strength higher, use steel and cement material is less, weight is light, it is less to take up room, and can effectively utilize pin formula gypsum formwork that industrial waste gypsum or ardealite use as constructional materials and the close rib arch without beam of Combined concrete and preparation method thereof, to overcome the deficiencies in the prior art.
The present invention is achieved in that the preparation method of a kind of pin formula gypsum formwork of the present invention and the close rib arch without beam of Combined concrete is, make the gypsum evacuated mould shell with industrial waste gypsum or ardealite first, and on the gypsum evacuated mould shell pre-buried Shear connection pin, then the gypsum evacuated mould shell is arranged in and builds the building on the support baseboard of superstructure, and make the gypsum evacuated mould shell of arranging reserve each other the headspace of the rib of concreting superstructure, then carry out concreting at the gypsum evacuated mould shell, after concrete setting, to build support baseboard and remove, and can obtain like this connecting to form pin formula gypsum formwork and the close rib arch without beam of Combined concrete that is integrated by the Shear connection pin with as the gypsum evacuated mould shell of permanent formwork and close rib and floor structure.
The of the present invention a kind of pin formula gypsum formwork and the close rib arch without beam of Combined concrete that make up according to the method described above are, this superstructure comprises with floor structure builds the close rib that is integrated, and is connected with gypsum evacuated mould shell as permanent formwork by the Shear connection pin in the space that floor structure and close rib surround.
The shape of the π font that two base plates that being shaped as of above-mentioned Shear connection pin become by steel plate bending and door font frame form.
The steel plate thickness of the Shear connection pin of the above-mentioned π of being bent into word shape is 2～10 millimeters; Its steel plate width is 10～150 millimeters.
Above-mentioned Shear connection pin be shaped as the curved planform that the right angle crotch is arranged in two ends at straight steel pole.
Owing to adopted technique scheme, the present invention adopts the gypsum evacuated mould shell as permanent formwork, and by the Shear connection pin rib and the floor structure that gypsum evacuated mould shell and concreting go out being connected to an organic whole structure, this structure is pin formula gypsum formwork of the present invention and the close rib arch without beam of Combined concrete structure.The present invention connects gypsum formwork and concrete with the Shear connection pin, makes them as cooperative shear connector, thereby has effectively improved shearing resistance and the flexural strength of whole superstructure.The present invention has adopted industrial waste gypsum or ardealite as constructional materials effectively, and this has not only reduced building costs, but also has reduced the pollution of industrial waste to environment.Particularly for Guizhou Province, Guizhou Province is one and has the area of enriching phosphate rock resource, be Chinese most important phosphorous chemical industry base, but phosphorous chemical industry produces a large amount of Industry Waste ardealite difficult treatment, contaminated environment.Therefore using all kinds of building materials of gypsum products of ardealite system is the highly effective approach that can process in a large number ardealite.Adopt produced pin formula gypsum formwork and the close rib arch without beam of Combined concrete of the present invention, through experimental test, under the test condition of national building standard defined, every intensity index all meets or exceeds the regulation of national building standard.So, the present invention compared with prior art, the present invention not only have structural strength higher, use steel and cement material is less, weight is lighter advantage, but also have structure height little, occupy little space, construct convenient, and can be effectively and the advantage of utilizing in a large number industrial waste gypsum or ardealite to use as constructional materials.Pin formula gypsum formwork of the present invention and the close rib arch without beam of Combined concrete also have the characteristics that can realize the architectural space flexible partition in use.The present invention can be widely used in huge pillar net parking lot, market and other utilities buildings and use, and its Transformation Application prospect is very wide.
