Description

Fireproof and decorative integrated steel beam

[ technical field ] A method for producing a semiconductor device

The utility model relates to a building element, concretely relates to fire prevention decorates integration girder steel belongs to building engineering technical field.

[ background of the invention ]

In recent years, with the strong push of our government to fabricated buildings, steel structures have become more and more widely used as a superior fabricated building structure system to fabricated PCs. Although the steel structure has the advantages of light weight, high strength and the like, the poor fire resistance is a more prominent disadvantage. The integration problem of corrosion resistance, fire resistance and decoration of a steel structure becomes one of bottlenecks which restrict the popularization and development of steel structure civil buildings, particularly assembled steel structure civil buildings to a certain extent.

Due to the lack of integrated design concepts of corrosion resistance, fire resistance and decoration of the steel structure, the problems of the designed structure, the landing property of construction and the actual situation of a construction site are easily caused in the project implementation stage, and the engineering cost is directly increased. Meanwhile, the steel member, especially the steel member of the outdoor exposed part, needs to comprehensively consider various factors such as energy conservation, heat bridge, fire prevention, decoration, door and window fixation and the like.

Therefore, in order to solve the above technical problems, it is necessary to provide an innovative integrated fireproof and decorative steel beam to overcome the above-mentioned drawbacks of the prior art.

[ Utility model ] content

The utility model discloses a fire prevention is decorated integration girder steel and is further set up to: the web and the flange are fully coated with intumescent fire-retardant coating; and a rock wool layer is filled in one side of the web plate.

The utility model discloses a fire prevention is decorated integration girder steel and is further set up to: and a galvanized anti-crack steel wire mesh is arranged on the outer side of the cement fiberboard.

The utility model discloses a fire prevention is decorated integration girder steel and is still set up to: and sealing paste is filled in gaps among the cement fiberboard, the structural floor slab and the window frame.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the utility model discloses a fire prevention is decorated integration girder steel and is synthesized and considered many-sided factors such as energy-conservation, heat bridge, fire prevention, decoration and AND gate window fixed, the fire prevention, the heat preservation, the decoration system problem that expose the girder steel are solved to the system.

2. The utility model discloses a fire prevention is decorated integration girder steel and is provided the assembled fitment solution that cooperatees, suits for the main part steel construction to solve and expose the unable direct plastering of girder steel, and plaster easy fracture problem in wall body and girder steel handing-over department.

Figure 1 is the utility model discloses a section view of fire prevention decoration integration girder steel.

[ detailed description ] embodiments

Referring to the attached drawing 1 of the specification, the present invention relates to a fireproof and decorative integrated steel beam, which is disposed between a structural floor 10 and a window frame 11, and comprises a steel beam 1, a steel plate 2, a wood plate 3, an anti-corrosion square wood 4, a cement fiber plate 5, etc.

The steel beam 1 is specifically H-shaped steel and is composed of a web 12 and flanges 13 vertically welded to two ends of the web 12. The flanges 13 are supported on the structural floor 10 and the window frame 11 respectively. The expansion fireproof coating 6 is fully coated on the web 12 and the flange 13, the requirement of the fire endurance of the steel beam 1 is met, and the fireproof problem of the steel beam is solved. Rock wool layer 7 is filled in one side of web plate 11, and the problems of heat preservation, sound insulation and the like of steel beam 1 are solved.

The steel plate 2 is welded to the web 12. The wood board 3 is mounted on the steel plate 2 through a wood screw 8. During specific installation, after a steel plate 2 with the thickness of 3mm and a wood plate 3 are fixed on the ground through wood screws 8, the steel plate 2 is welded with a web 13 of a steel beam 1 as a whole.

The anti-corrosion square timber 4 is nailed on the wood board 3 through nails; the cement fiberboard 5 is nailed on the anti-corrosion square timber 4 through nails, so that the installation of the cement fiberboard 5 is facilitated, and the damage to the fireproof paint of the steel girder caused by the fact that the steel angle is welded on the steel girder on the spot in the prior art is avoided. The cement fiberboard 5 covers the outer side of the steel beam 1.

Further, the galvanized anti-crack steel wire mesh 9 is arranged on the outer side of the cement fiberboard 5, and the galvanized anti-crack steel wire mesh 9 can prevent the decorative plastering layer from cracking due to deformation of the main body structure. And a 10mm open joint is arranged between the cement fiberboard 5 and the structural floor slab 10 and between the cement fiberboard and the window frame 11, and sealing paste 14 is filled in the joint.

The fire-proof and decoration integrated steel beam of the utility model comprehensively considers various factors such as energy conservation, heat bridge, fire prevention, decoration, door and window fixation and the like, and systematically solves the problems of fire prevention, heat preservation and decoration system of the exposed steel beam; simultaneously, provide the main part steel construction and cooperate, the assembled fitment solution that suits to solve and expose the unable direct plastering of girder steel, and plaster easy fracture problem in wall body and girder steel handing-over department.

The above embodiments are merely preferred embodiments of the present disclosure, which are not intended to limit the present disclosure, and any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present disclosure, should be included in the scope of the present disclosure.
