Description
The application is a divisional application entitled 'effective method for fire prevention of high-rise steel structure building', wherein the application number of a parent application is 201810025530.X, and the application date is 2018.01.03.
Technical Field
The invention relates to the technical field of building fire prevention, in particular to an effective method for fire prevention of a high-rise steel structure building.
Background
When the steel construction is used in high-rise buildings, its fire prevention problem is very outstanding: in case of fire, the steel structure building member is heated to increase its temperature and lose its bearing capacity, thereby causing collapse of the building. Therefore, the fire protection performance of the steel structure building is improved by substantially preventing the problem that the bearing capacity of the member is lost due to the temperature of the stressed member of the steel structure is greatly increased when a fire disaster occurs, so that the fire protection performance of the steel structure building is improved.
At present, the method for solving the fire prevention of the high-rise steel structure building is to coat a heat insulation material on the surface of a stress structural member beam column of a frame steel structure or install the heat insulation material, so that the structural member beam column of the stress frame steel structure is not easy to lose bearing capacity due to the rise of temperature because of the blockage of the heat insulation material when a fire disaster occurs, and the collapse of the building is caused. However, this method has serious drawbacks: the surface of the beam and column is coated with an insulating material or installed with an insulating material to have a limited ability to block heat conduction: the temperature of the structure can only be ensured not to increase within a certain time. Particularly, when the heat insulating material is coated or the heat insulating material is wrapped to locally fall off (the situation that the heat material locally falls off is difficult to avoid), the steel structure stressed member at the falling part loses bearing capacity and collapses due to the increase of temperature in a short time, so that more parts of the fireproof coating or the fireproof heat insulating plate are damaged, a large number of steel structure stressed members lose bearing capacity due to the sharp rise of the protection temperature of losing the fireproof heat insulating property in a short time, and further the whole collapse of the building is caused.

In order to make the aforementioned objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description thereof.
As shown in fig. 1 and 2, the embodiment provides an effective method for fire protection of a high-rise steel structure building, wherein a fire protection spray pipe 1 is installed along the axis of a stressed member of a steel structure frame, and the fire protection spray pipe 1 is installed between the stressed member and a fire protection heat insulation plate 5 outside the stressed member. The fire prevention shower 1 in this embodiment sprays water towards the outer wall surface of atress component, and then realizes the cooling of atress component.
Specifically, the wall surface of the fireproof spray pipe 1 is provided with at least one row of holes 2 which are distributed along the length direction of the fireproof spray pipe 1 and face the stress member, so that the water in the fireproof spray pipe 1 is ensured to be continuously sprayed to the outer wall surface of the stress member. Namely, the wall surface of the fireproof spray pipe 1 is provided with one or more rows of holes 2 distributed along the length direction of the fireproof spray pipe 1, and at least one row of holes 2 faces to the stress member.
In this embodiment, the fire shower 1 is a metal pipe.
In this embodiment, as shown in fig. 1, the stressed member includes a non-solid column 3 and a non-solid beam 4, a fire-proof shower 1 is installed at a gap between the non-solid column 3 and a fire-proof heat-insulating plate 5 outside the non-solid column 3, and a fire-proof shower 1 is installed at a gap between the non-solid beam 4 and the fire-proof heat-insulating plate 5 outside the non-solid beam 4. The non-solid columns 3 are steel columns, and the non-solid beams 4 are steel beams. The fireproof heat insulation plates 5 installed according to the traditional method are arranged outside the non-solid columns 3 and the non-solid beams 4, meanwhile, fireproof spray pipes 1 parallel to the axes of the non-solid columns 3 and the non-solid beams 4 are installed at the hollow parts of the non-solid columns 3 and the non-solid beams 4, and holes 2 are formed in the wall surfaces, close to the columns, of the fireproof spray pipes 1. The spraying system supplies water to the fireproof spraying pipe 1 when a fire disaster occurs, so long as in the process of fire disaster occurrence, water in the pipe is continuously and directly sprayed to the beam column through the hole 2 on the wall surface of the fireproof spraying pipe 1, so that the beam column is cooled, the temperature rise amplitude of the beam column can be effectively controlled, and in the process of fire disaster occurrence, the temperature of the beam column is not too high, so that the bearing capacity cannot be lost, and the collapse of a building is not caused.
Specifically, both the non-solid column 3 and the non-solid beam 4 are at least one, the non-solid beam 4 is installed on one side of the non-solid column 3, and the fireproof spray pipe 1 installed on the non-solid column 3 is communicated with the fireproof spray pipe 1 installed on the non-solid beam 4. A plurality of fire prevention shower 1 of installing in steel structural framework are linked together and constitute pipeline spray cooling system, and then are convenient for control a plurality of fire prevention shower 1 among the pipeline spray cooling system.
