Because the girder steel is internally and concentrically provided with the supporting beam, and at least 2 spiral separation ribs are arranged between the supporting beam and the girder steel. Therefore, a spiral water flow channel can be formed between the supporting beam and the steel beam, on the premise of keeping the inherent length of the steel beam, the length of the water flow channel is prolonged, the heat exchange efficiency is increased as much as possible, the temperature of the steel beam is reduced, the cross section of the water flow channel is reduced as much as possible, the water consumption is reduced, and the water flow speed and the heat exchange efficiency are improved.
Preferably, a plurality of water outlets are formed in the surface of the steel beam, corresponding to the water flow channel, at equal intervals, the water outlets are obliquely arranged, and the water outlets are obliquely arranged from inside to outside along the direction of the water flow channel.

In the figure: 1. the fire-fighting water supply device comprises a steel frame 11, steel beams 111, a water flow channel 112, water outlet holes 12, supporting beams 13, separation ribs 2, a fire-fighting water supply device 21, a water outlet end 22 and a water return end.
Detailed Description
The utility model is further described below with reference to the drawings and detailed description.
A steel structure with fireproof effect, preferably a structure made of steel profiles, such as fireproof doors, which needs to isolate fire so as to improve safety. Specifically, the steel structure with fireproof effect comprises a fireproof mechanism arranged in the steel structure, as shown in fig. 1 and 2, the fireproof mechanism comprises a steel frame 1, the steel frame comprises a plurality of steel beams 11 with hollow interiors, the steel beams are mutually connected, so that a water flow channel 111 which is mutually communicated is formed in the steel frame, one end of the water flow channel is connected with a water outlet end 21 of the fire-fighting water supply device 2, and the other end of the water flow channel is connected with a water return end 22 of the fire-fighting water supply device, so that the fireproof mechanism has better fireproof effect.
When encountering a fire, the water outlet end of the fire-fighting water supply device can output fire-fighting tap water, and the fire-fighting tap water enters the water flow channel in the steel frame through the pipeline, so that the steel frame which is heated up rapidly by fire barbecue is cooled down rapidly, and the fire-fighting personnel can operate the fire-fighting mechanism conveniently. For many buildings, fire-fighting water supply devices such as fire-fighting water taps are usually installed in specific areas. Of course, the fire water supply device can also comprise a pumping device and a heat dissipation device, so that when the pumping device enables water flow of the fire water supply device to flow back to the fire water supply device through the water return end, heat dissipation and temperature reduction can be performed at the heat dissipation device, and the water flow of the fire water supply device can be reused conveniently.
Because the main effect of the fire prevention mechanism in the steel structure is to isolate the fire, but not extinguish the fire, and the water flow channel is in a sealed circulation state that one end is connected with the water outlet end of the fire water supply device and the other end is connected with the water return end, the rapid temperature rise of the fire prevention mechanism in the steel structure caused by the rapid evaporation of water flow can be effectively avoided, thereby facilitating the operation of fire fighters on the fire prevention mechanism and further being beneficial to fire fighting.
As a preferable scheme, as shown in fig. 3, the steel beam may be made of a metal profile matched with the whole structure, such as a steel round tube, a square tube, or a stainless steel round tube, a square tube, etc., so as to increase aesthetic feeling. Furthermore, a support beam 12 may be concentrically disposed within the steel beam and connected between the support beam and the steel beam by at least 2 helical spacer fins 13, thereby forming a helical water flow path between the support beam and the steel beam. That is, the cross section of the support beam is similar to the internal control cross section of the steel beam, and the support beam itself may be a pipe.
Because the length of the spiral water flow channel is longer than that of the linear water flow channel, the spiral water flow channel can keep the inherent length of the steel beam unchanged and prolong the length of the water flow channel so as to reduce the temperature of the steel beam and improve the heat exchange efficiency of the steel beam.
Furthermore, a plurality of water outlets 112 may be disposed on the surface of the steel beam at equal intervals corresponding to the water flow channel, that is, the water outlets are arranged in a spiral shape like the water flow channel, and the water outlets are inclined from inside to outside along the direction of the water flow channel.
Thus, when fire water flows in the water flow channel, the fire water can be sprayed outwards in an inclined way through the water outlet. That is, the water flow of the small column sprayed outwards through the water outlet can be effectively sprayed to the surface of the steel beam, so that unnecessary waste of the water flow is avoided, the surface temperature of the steel beam is effectively reduced, and the operation of fire rescue workers is facilitated.
Of course, the sum of the cross sections of all the water outlet holes should be equal to 20% -30% of the cross section of the water flow channel, that is, the cross section of all the water outlet holes should be smaller than the cross section of the water flow channel so as to enable the water flow sprayed outwards through the water outlet holes to have a certain flow rate and pressure, and the surface temperature of the steel beam and the flow rate of the water flow in the water flow channel can be maintained at proper levels.
