Description
Technical field
Long strands field is the utility model is related to, more particularly to fire preventing steel structure for building.
Background technology
Steel construction is the structure being mainly made up of steel material, is one of main building construction types.Steel construction is main The component such as girder steel, steel column, steel truss forms made of shaped steel and steel plate etc., generally use weld seam between each component or part, Bolt or rivet interlacement.Because its deadweight is lighter, and easy construction, it is widely used in the fields such as large-sized workshop, venue, Super High. Commonly used with steel construction, requirement of the building to the fire-proof high-temperature resistant performance of steel construction also gradually rises.Conventional is anti- Fiery steel construction is generally only to coat fireproof coating on the surface of steel construction, when running into fire, although this steel construction can play Certain delays thermogenic action, but still can not be born after temperature rise, and fire protecting performance is poor.
At present, patent application also points out to set up water cavity inside steel construction, to its interior water supply, and then using water come to steel The fire prevention of structure carries out last guarantee, but the setting of the structure is to play a role for small fire, when the intensity of a fire becomes The condition of a fire is not easily controlled after big, and loads the steel construction of water, easily corrosion, and load-carrying properties are bad, are not good solution party Case.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of fire resistance, decay resistance Fire preventing steel structure for building.
Technical scheme is used by the utility model：Fire preventing steel structure for building, including steel construction main body and both ends connection Several logical inner bag units, the outside of each inner bag unit is at least cased with an enhancing clip, at the top of steel construction Inner bag unit is provided with air inlet, and the inner bag unit close to steel construction bottom is provided with water inlet, while each two is connected with each other Inner bag unit link position at be provided with sealing structure；And some air vents are additionally provided with the surface of steel construction main body.
Further, opening position of the steel construction main body close to bottom is additionally provided with openable wicket, openable wicket Height and width meet that an inner bag unit can pass in and out an inner bag unit, are convenient for changing inner bag unit, repair simultaneously.
Further, it is loop configuration to strengthen clip, and its loop configuration outer surface is provided with least eight uniform cloth The vertical enhancing muscle put.
Further, inner bag unit is made up of one kind in PVC, PC material, and is also coated with flame-retardant layer on its outer surface.
Further, the bottom of steel construction main body is additionally provided with flaring structure, and the height of the flaring structure is 30-50cm.
Compared with prior art, the beneficial effects of the utility model are：Fire preventing steel structure for building of the present utility model, will Steel construction uses three layers structure, is followed successively by outermost steel construction main body, enhanced card cuff-layer and inner bag elementary layer, while inside Coolant is set in courage elementary layer, and coolant can be water or other cooling waters, while the inner bag that each two is connected with each other Unit is sealed at its link position using sealing structure, ensures that fire preventing steel structure has preferable fire resistance and resistance to Corrosive nature.In addition, fire preventing steel structure of the present utility model has also set some air vents in the outside of steel construction main body, these are logical Air holes ensures that the outer surface of enhancing clip and inner bag unit has preferable ventilation effect, places the corrosion of both parts, tool There is more preferable anticorrosion ability.
Brief description of the drawings
Fig. 1 is the structure chart of one embodiment of fire preventing steel structure for building；
Wherein：1- steel construction main bodys, 11- flaring structures；2- inner bag units, 3- enhancing clips, 4- water inlets, 5- sealing knots Structure, the openable wickets of 6-, 7- air vents, 8- air inlets.
Embodiment
In order to deepen to understanding of the present utility model, with reference to the accompanying drawings and examples to the utility model furtherly Bright, the embodiment is only used for explaining the utility model, and the scope of protection of the utility model is not formed and limited.
As shown in figure 1, fire preventing steel structure for building, including several inner bag units of steel construction main body 1 and both ends UNICOM 2, the outside of each inner bag unit 2 is at least cased with an enhancing clip 3, and the inner bag unit 2 at the top of steel construction is provided with Air inlet 8, the inner bag unit 2 close to steel construction bottom are provided with water inlet 4, while the inner bag unit 2 that each two is connected with each other Link position at be provided with sealing structure 5；And some air vents 7 are additionally provided with the surface of steel construction main body 1.
In the above-described embodiments, opening position of the steel construction main body 1 close to bottom is additionally provided with openable wicket 6, can open Wicket 6 height and width meet an inner bag unit 2 can pass in and out an inner bag unit, be convenient for changing inner bag unit, together Shi Weixiu.
In the above-described embodiments, enhancing clip 3 is loop configuration, and its loop configuration outer surface is provided with least eight The vertical enhancing muscle being evenly arranged, enhances the bulk strength of steel construction, while has preferable performance of ventilating and antiseptic property.
In the above-described embodiments, inner bag unit 2 is made up of one kind in PVC, PC material, and is also coated with its outer surface Flame-retardant layer, preferable flame retardant effect can be also played, there is preferable fire resistance.
In the above-described embodiments, the bottom of steel construction main body 1 is additionally provided with flaring structure 11, and the height of the flaring structure is 30-50cm is more convenient to safeguard there is good fire resistance to inner bag unit.
It is described in synthesis, fire preventing steel structure for building of the present utility model, steel construction is used into three layers structure, is followed successively by Outermost steel construction main body, enhanced card cuff-layer and inner bag elementary layer, while coolant, coolant are set in inner bag elementary layer Can be water or other cooling waters, while the inner bag unit that each two is connected with each other is tied at its link position using sealing Structure is sealed, and ensures that fire preventing steel structure has preferable fire resistance and decay resistance.
In addition, fire preventing steel structure of the present utility model has also set some air vents in the outside of steel construction main body, these are logical Air holes ensures that the outer surface of enhancing clip and inner bag unit has preferable ventilation effect, places the corrosion of both parts, tool There is more preferable anticorrosion ability.
What embodiment of the present utility model was announced is preferred embodiment, but is not limited thereto, the common skill of this area Art personnel, easily according to above-described embodiment, understand spirit of the present utility model, and make different amplification and change, but as long as Spirit of the present utility model is not departed from, all in the scope of protection of the utility model.
