Description

Insulated fire formed steel construction

Technical field

The present invention relates to field of steel structure, especially a kind of insulated fire formed steel construction vdiverse in function.

Background technique

Steel are a kind of construction materials that will not be burnt, it has the characteristics such as antidetonation, bending resistance.In practical applications, steel Both the needs of architectural design aesthetic feeling moulding can also be can satisfy, it is thus also avoided that coagulation with the weight bearing power of relative increase building The defect that the construction materials such as soil cannot be bent, stretch, therefore steel receive the favor of building trade, single layer, multilayer, skyscraping are big Building, workshop, storehouse, waiting room, boarding lounge etc. are all very universal using steel.But steel as construction material in terms of fire prevention Have the defects that again it is some be difficult to avoid that, its mechanical performance, such as yield point, tension and elasticity modulus can be because of the liters of temperature It is high and sharply decline.Steel construction will lose bearing capacity usually in higher temperature, and very big deformation occurs, cause steel column, Girder steel bending, as a result cannot be used continuously because of excessive deformation, and the fire endurance that the steel construction of protection is generally not added is tens Minute or so.The length of this time is also related with the speed of component heat absorption.

Steel structure material is set to overcome the shortcomings of fire prevention aspect in practical applications, it is necessary to carry out fire prevention processing, purpose The fire endurance of steel construction is exactly increased to limit range as defined in design specification.Steel construction is prevented to be brought rapidly up in a fire Slump that deformation occurs, measure are diversified, it is important to distinct methods are taken according to different situations, such as use insulation, Refractory material obstruct the direct calcination steel construction of flame, reduce heat transfer speed postpone steel construction temperature rise, weakened when Between etc..

Currently, steel construction accessory has been widely used in all trades and professions, have from heavy and light, intensity is high, stability is strong.It is anti- Fiery mode is prevented fires generally by way of priming petock in the inner cavity in steel construction.But due in a part of steel construction Portion's space problem, the water that can be poured into cavity can not be too many, and when fire is larger, effect can be cut down significantly.

Summary of the invention

In order to overcome deficiency existing for existing technology, the present invention provides a kind of insulated fire formed steel construction, and the present invention is set Water and sodium chloride have been set, has been cooled down by the endothermic effect of hydrolysis to steel construction, the interior of steel construction is effectively utilized Cavity space, while there is easy to process, the simple advantage of structure.

The technical solution adopted by the present invention to solve the technical problems is: the present invention includes steel construction ontology, insulating layer, prevents Fiery plate, exocoel, inner cavity, coolant, water pipe, water pump, water source, valve, film;Steel construction body surface has one layer of fire-proof plate, steel Be insulating layer in structural body, steel construction ontology side is equipped with exocoel, it is outer it is intracavitary have coolant, the exocoel has with interlayer is kept the temperature Channel is interconnected, and channel is sealed by film, and insulating layer side is inner cavity, and inner cavity side connects water pipe, valve is arranged on water pipe, Water pipe connects water source by water pump.

Further, the steel construction ontology is I-steel.

Further, the fire-proof plate material is ca silicate fibre plate.

Further, the fire-proof plate is with a thickness of one to three centimetres.

Further, the fire-proof plate of the exocoel side is with a thickness of two to five centimetres.

Further, the coolant is ammonium chloride.

Further, the exocoel and heat preservation interlayer have channel to be interconnected.

The invention has the advantages that space is inadequate in the cavity of traditional certain steel constructions, cool down only by water filling Effect is not satisfactory, and the present invention is provided with water and sodium chloride, is cooled down by the endothermic effect of hydrolysis to steel construction, is had The intracavity space of steel construction is utilized in effect, while having easy to process, the simple advantage of structure.

Specific embodiment

In the embodiment shown in fig. 1, the present invention include steel construction ontology 1, insulating layer 2, fire-proof plate 3, exocoel 4, inner cavity 5, Coolant 6, water pipe 7, water pump 8, water source 9, valve 10, film 11.There are one layer of fire-proof plate 3, steel construction sheet in 1 surface of steel construction ontology It is insulating layer 2 in body 1,1 side of steel construction ontology is equipped with exocoel 4, has coolant 6 in exocoel 4, between the exocoel 4 and insulating layer 2 There is channel to be interconnected, channel is sealed by film 11, and 2 side of insulating layer is inner cavity 5, and 5 side of inner cavity connects water pipe 7, on water pipe 7 Valve 10 is set, and water pipe 7 connects water source 9 by water pump 8.

Specifically, the steel construction ontology 1 is I-steel.

Specifically, the fire-proof plate material is ca silicate fibre plate;The fire-proof plate is with a thickness of one to three centimetres;It is described outer The fire-proof plate of chamber side is with a thickness of two to five centimetres.

Specifically, the coolant 6 is ammonium chloride;There is channel to be interconnected between the exocoel 4 and insulating layer 2.

When it is implemented, a kind of safe formed steel construction of fireproof heat insulating, including steel construction ontology 1, steel construction ontology 1 are I-shaped Steel, 1 surface of steel construction ontology cover one layer of fire-proof plate 3, and fire-proof plate is with a thickness of 2cm, and material is ca silicate fibre plate.Calcium silicates Fiberboard be using lime, silicate and inorfil reinforcing material as the building board of primary raw material, have light, intensity high and The features such as thermal insulation, durability are good, processing performance and workability are excellent.

1 side of steel construction ontology is equipped with exocoel 4, has coolant 6 in exocoel 4.There is channel mutual between exocoel 4 and insulating layer 2 Connection, but channel is sealed by film 11.The coolant 6 is ammonium chloride.When temperature increases, film 11 can be received under heating status It contracts, the coolant 6 in exocoel 4 can enter inner cavity 5 by channel, open valve 10 at this time, and water pump 8 is started to work, and water source 9 passes through Water pipe 7 flows to inner cavity 5, and ammonium chloride can hydrolyze when being dissolved in water as strong acid weak base salt.It can be absorbed when hydrolysis big The heat of amount, this can reduce the temperature of steel.

As known by the technical knowledge, the present invention can pass through the embodiment party of other essence without departing from its spirit or essential feature Case is realized.Embodiment disclosed above, in all respects are merely illustrative, not the only.It is all this It is included in the invention in invention scope or in the change being equal in the scope of the present invention.
