Description
[technical field]
The utility model relates to a kind of fire resisting supporting beams for building.
[background technique]
The supporting beam of steel construction is often used in building as main support construction, steel construction when there is fire behavior
The temperature of supporting beam will appear and largely increase, after steel temperature increases, the yield strength of steel can larger journey
The reduction of degree, or even there is the risk of building collapse, cause biggish risk and accident.
[utility model content]
The technical problem to be solved by the present invention is to provide a kind of fire resisting supporting beam for building, the utility model
After the installation of fire resisting supporting beam, first passes through water inlet and inject water (but cannot fill) in seal chamber, then clog pressure relief plug
Relief hole simultaneously closes valve, and when fire behavior occurs, the water in seal chamber can absorb a large amount of heat, can avoid the temperature of I-steel
There is raising by a relatively large margin, after the temperature of water in seal chamber is increased to boiling, the air pressure in seal chamber is increased until punching
Pressure relief plug is opened, so that a large amount of steam is sprayed from relief hole, the space being relatively isolated from is formed, further protects supporting beam, make
Supporting beam is in safer temperature range, plays good protection and cooling to supporting beam, avoids I-steel from occurring larger
The temperature rise of degree and reduce its intensity, after a while, fire is extinguished, and after checking supporting beam, is infused again
Enter water and add pressure relief plug, close valve, and structure is simple, is easy to implement.
In order to solve the above technical problems, a kind of fire resisting supporting beam for building of the utility model, including as main branch
The notch of the I-steel of support, the I-steel is equipped with side plate, and the both ends of the I-steel are respectively equipped with cover board, so that I-shaped
Be formed with hollow seal chamber between steel, side plate and two cover plates, the top of the cover board be equipped with communicated with seal chamber into
The mouth of a river is connected with valve on the water inlet, and the top of the side plate is equipped with multiple relief holes communicated with seal chamber, described
Relief hole on be connected with pressure relief plug.
A kind of fire resisting supporting beam for building as described above, is equipped with extremely between the notch and side plate of the I-steel
Few one piece of deep floor, the deep floor are equipped with through-hole.
A kind of fire resisting supporting beam for building as described above, the side plate, cover board and deep floor weld
On I-steel.
A kind of fire resisting supporting beam for building as described above, the I-steel, side plate, cover board and deep floor
Surface be coated with for preventing by the corrosion-inhibiting coating of the aqueous corrosion in seal chamber.
Compared with prior art, the utility model has the advantages that
1, after the fire resisting supporting beam installation of the utility model, first pass through water inlet water is injected in seal chamber (but cannot
Fill), pressure relief plug is then clogged into relief hole and closes valve, when fire behavior occurs, the water in seal chamber is absorbable a large amount of
Heat can avoid the raising of the temperature appearance of I-steel by a relatively large margin, close after the temperature of water in seal chamber is increased to boiling
It seals intracavitary air pressure to increase until washing pressure relief plug open, so that a large amount of steam is sprayed from relief hole, forms the sky being relatively isolated from
Between, supporting beam is further protected, so that supporting beam is in safer temperature range, good protection and drop is played to supporting beam
Temperature avoids I-steel from largely temperature rise occur and reduce its intensity, and after a while, fire is extinguished, to support
It after beam is checked, refills water and adds pressure relief plug, close valve, and structure is simple, is easy to implement.
[Detailed description of the invention]
Specific embodiment of the present utility model is described in further detail with reference to the accompanying drawing, in which:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the exploded view of the utility model.
[specific embodiment]
It elaborates with reference to the accompanying drawing to the embodiments of the present invention.
As depicted in figs. 1 and 2, a kind of fire resisting supporting beam for building of the present embodiment, including the work as main support
The notch of word steel 1, the I-steel 1 is equipped with side plate 2, and the both ends of the I-steel 1 are respectively equipped with cover board 3, so that I-steel
1, it is formed with hollow seal chamber between side plate 2 and two cover plates 3, the top of the cover board 3 is equipped with to be communicated with seal chamber
Water inlet 31 is connected with valve (not showing in attached drawing) on the water inlet 31, the top of the side plate 2 be equipped with it is multiple with it is close
The relief hole 21 that chamber communicates is sealed, is connected with pressure relief plug 4 on the relief hole 21；The fire resisting supporting beam of the utility model installs it
Afterwards, it first passes through water inlet and injects water (but cannot fill) in seal chamber, pressure relief plug is then clogged into relief hole and closes valve,
When fire behavior occurs, the water in seal chamber can absorb a large amount of heat, can avoid the liter of the temperature appearance of I-steel by a relatively large margin
Height, after the temperature of water in seal chamber is increased to boiling, the air pressure in seal chamber is increased until washing pressure relief plug open, so that largely
Steam sprayed from relief hole, form the space being relatively isolated from, further protect supporting beam, make place in the supporting beam long period
In safer temperature range, good protection and cooling are played to supporting beam, avoid I-steel from occurring largely warm
It rises and reduces its intensity, after a while, fire is extinguished, and after checking supporting beam, is refilled water and is added
Upper pressure relief plug closes valve, and structure is simple, is easy to implement.
In order to reinforce I-steel 1, while good support carried out to side plate, the notch and side plate 2 of I-steel 1 it
Between be equipped at least one piece of deep floor 5, deep floor 5 is equipped with through-hole 51, and through-hole 51 flows in seal chamber convenient for water.
In the present embodiment, side plate 2, cover board 3 and deep floor 5 are welded on I-steel 1.
In order to avoid the water in seal chamber generates largely I-steel 1, side plate 2, cover board 3 and deep floor 5
Corrosion is coated with corrosion-inhibiting coating on the surface of I-steel 1, side plate 2, cover board 3 and deep floor 5.
