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 building trade
Extensive application;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, and its architectural mode is
Using steel construction to set up the load-carrying members in house, namely column and girder steel, these girder steels use shaped steel to make mostly, and these
Shaped steel includes 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,
It is internally formed certain cavity at section bar, while ensureing support strength, reduces material usage and structural weight per square meter;But, due to
This construction features of shaped steel, the fire protecting performance of steel building is restricted, be referred to as hindering steel building fast-developing and
One of major reason promoted, because steel start to soften at a temperature of about 850 °, the softening of shaped steel is to steel building
Meaning that collapsing and damaging of building, 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 that later-stage secondary is fitted up
And decoration.
Summary of the invention
The light-gauge steel section tolerable temperature existed for existing steel building is the highest, it is impossible to the problem arriving 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 of a kind of steel building
Fireproof construction, it is characterised in that: include shaped steel, surface layer, spraying slurry;Described shaped steel is the structural member of steel construction Modular building
Such as the C-type steel of thin-walled, H profile steel, I-steel, the surface layer described in channel-section steel is sprayed on the outer surface of spraying slurry, is and spraying slurry
But constituent class is same a kind of spraying slurry that proportioning is different, and is completely covered by spraying slurry;Described spraying slurry is sprayed on
The inner chamber of shaped steel and outer surface, and by full for the inner chamber filling of shaped steel, the shaped steel cross section after spraying be shaped steel periphery be periphery
Solid section;Described spraying slurry is to include Gypsum Fibrosum, cement, the mixture of expanded perlite, is that earlier application is " a kind of existing
Rapid solidification flame-retardant slurry is built in field 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
Net;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, formed and traditional architecture member section
Identical profile, 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
Fig. 1, in this example with height 200 millimeters, as a example by the H profile steel of the steel building column of width 200 millimeters, by H profile steel according to
Design requires to be arranged on the assembly of steel construction as shaped steel 1;Select the steel wire of aperture 5 millimeter as steel wire
Net 2, and it is welded to the inner chamber of H profile steel;Select the proportioning of spraying slurry 4 of Gypsum Fibrosum and light granules large percentage as face
Layer material, and it is sprayed on the outer surface of spraying slurry 4 as surface layer 3;Selecting light granules is the scene of expanded perlite
Spray builds rapid solidification flame-retardant slurry as spraying slurry 4;Spraying slurry 4 is required difference, by individual group according to the design of building
Distribution ratio mixes, and sends into pulp shooting machine after the stirring that adds water, and the inner chamber at shaped steel 1 sprays, until the inner chamber of shaped steel 1 is full of, and will spray
It is coated with the outer surface leveling of slurry 4, the most concordant with the edge of shaped steel 1, and at the surface layer 3 of its surface spraying thickness 5 millimeters, so
The cross section of the shaped steel 1 after spraying is known as the square-section of standard, identical with traditional beam or pillar;Just complete the present invention
Enforcement;Shaped steel after having sprayed proves according to GB/T9978.6/2008 detection through authority testing agency, and fire resistance is more than
Equal to 4 hours, it is possible to meet the fire protecting performance requirement of building structural member, be suitable for the aesthetical standard of traditional architecture, it is simple to two simultaneously
Secondary finishing.
