Abstract
The invention relates to a shape steel fireproof structure of a steel structure building and belongs to the field of construction. The shape steel fireproof structure comprises shape steel, a surface layer and a sprayed sizing agent. The shape steel is a structural member of a steel structure standard building, such as a thin-wall C-shaped steel, H-shaped steel, I-shaped steel and groove steel. The surface layer is sprayed on the outer surface of the sprayed sizing agent and is a sprayed sizing agent which has ingredients similar to ingredients of the sprayed sizing agent but is different in ratio, and completely covers the sprayed sizing agent. The sprayed sizing agent is sprayed on an inner cavity and the outer surface of the shape steel and fills the inner cavity of the shape steel, and the cross section of the shape steel after the spraying is a peripheral solid cross section of the shape steel. The shape steel fireproof structure has the advantages of being capable of being well combined with the steel structure shape steel, forming the same outline as a conventional building component cross section and being capable of meeting the fireproof requirements of the steel structure building.
Description
Technical field
The invention belongs to building field, particularly to the shaped steel fireproof construction of a kind of steel building.
Background technology
It is fast that steel building has building speed, and the advantages such as building waste is few, simple for structure, and span is big obtain the extensive application of building trade；Feature due to steel building, initial steel building originates from industrial building and temporary building, along with steel building technology and the progress of material manufacturing technology, steel construction starts application and builds with civic building, its architectural mode is the load-carrying members using steel construction to set up house, namely column and girder steel, and these girder steels use shaped steel to make mostly, and these shaped steel include C-type steel, H profile steel, channel-section steel, I-steel；In order to alleviate the weight of building, these shaped steel use thin-wall section mostly, are internally formed certain cavity at section bar, reduce material usage and structural weight per square meter while ensureing support strength；But, this construction features due to shaped steel, the fire protecting performance of steel building is restricted, one of major reason being referred to as hindering steel building fast-developing and promote, because steel start to soften at a temperature of about 850 °, to steel building, the softening of shaped steel means that building collapses and damages, such temperature capabilities is can not be received under running into case of fire；In order to improve the fire protecting performance of steel construction shaped steel, prior art have employed the method at shaped steel surface-coated fireproof coating, in order to improve the fire protecting performance of steel construction shaped steel, owing to fireproof paint coating is thin, inadequate with the adhesion of steel, often produce cracking, remain the basic profile of shaped steel simultaneously in the shaped steel profile being coated with fireproof coating, be the most also unfavorable for later-stage secondary finishing and decoration.
Summary of the invention
The light-gauge steel section tolerable temperature existed for existing steel building is the highest, the problem that can not arrive fire protection requirement, and it is aesthetic to meet traditional architecture, the problem being not easy to secondary decoration, the present invention proposes the shaped steel fireproof construction of a kind of steel building, it is characterized in that: include shaped steel, surface layer, spraying slurry；Described shaped steel is the C-type steel of the structural member such as thin-walled of steel construction Modular building, H profile steel, I-steel, the surface layer described in channel-section steel is sprayed on the outer surface of spraying slurry, it is a kind of spraying slurry that still proportioning different same from spraying slurry constituent class, and spraying slurry is completely covered；Described spraying slurry is sprayed on inner chamber and the outer surface of shaped steel, and by full for the inner chamber filling of shaped steel, the shaped steel cross section after spraying be shaped steel periphery be the solid section of periphery；Described spraying slurry is to include Gypsum Fibrosum, cement, the mixture of expanded perlite, is earlier application " rapid solidification flame-retardant slurry is built in a kind of on-the-spot spray " (application number: 2012105879745).
In order to enable spraying slurry to be preferably combined and to improve self-strength with shaped steel, above structure increases steel wire；Described steel wire is laid on shaped steel inner chamber, and fixing with shaped steel is connected, and is wrapped in inside spraying slurry.
Beneficial effect
The beneficial effects of the present invention is, it is possible to be combined very well with steel construction shaped steel, form the profile identical with traditional architecture member section, it is possible to meet the fire protection requirement of steel building.
Accompanying drawing explanation
Fig. 1 is the cross-sectional structure schematic diagram of the present invention
1. shaped steel, 2. steel wire, 3. surface layer, 4. spraying slurry.
Detailed description of the invention
In order to further illustrate technical scheme, in conjunction with accompanying drawing, the detailed description of the invention of the present invention is described；As in Fig. 1, this example with height 200 millimeters, as a example by the H profile steel of the steel building column of width 200 millimeters, using H profile steel according to design require be arranged on the assembly of steel construction as shaped steel 1；The steel wire of selection aperture 5 millimeter is as steel wire 2, and is welded to the inner chamber of H profile steel；The proportioning of the spraying slurry 4 of selection Gypsum Fibrosum and light granules large percentage is as surface material, and is sprayed on the outer surface of spraying slurry 4 as surface layer 3；The on-the-spot spray selecting light granules to be expanded perlite builds rapid solidification flame-retardant slurry as spraying slurry 4；Spraying slurry 4 is required difference according to the design of building, individual component proportion is mixed, add water and after stirring, send into pulp shooting machine, inner chamber at shaped steel 1 sprays, until being full of by the inner chamber of shaped steel 1, is flattened by the outer surface of spraying slurry 4, the most concordant with the edge of shaped steel 1, and it is known as the square-section of standard at the surface layer 3 of its surface spraying thickness 5 millimeters, the so cross section of the shaped steel 1 after spraying, identical with traditional beam or pillar；Just complete the enforcement of the present invention；Shaped steel after having sprayed proves according to GB/T9978.6/2008 detection through authority testing agency, and fire resistance is more than or equal to 4 hours, it is possible to meets the fire protecting performance requirement of building structural member, is suitable for the aesthetical standard of traditional architecture, it is simple to secondary decoration simultaneously.
