Embodiment: a kind of steel column fireproof structure, as shown in Figure 1, including the H-shaped cylinder 1 in section, 1 periphery of cylinder passes through
Building adhesive 13(such as Fig. 2) if being bonded with the rock wool board 14 that capable person's cylinder 1 surrounds, rock wool board 14 is the main body of fireproof construction, number
Amount is four, and thickness is 50mm, and its outer profile is in rectangle when rock wool board 14 surrounds cylinder 1, and each rock wool board 14 deviates from column
The side of body 1, which is all covered with, enhances silicate fire-proof plate 15 with a thickness of the thick fiber of 12mm, and thick fiber enhances silicate fire-proof plate
15 are connect by fastener with cylinder 1, and convenience flexible for installation improves construction efficiency.
As shown in Figure 1, rock wool board 14 and thick fiber enhancing silicate fire-proof plate 15 all have fire protecting performance, cylinder 1 is being given
In cylinder 1 is enclosed in while double protection is provided, thus when fire behavior occurs, rock wool board 14 and thick fiber enhancing silicate
Fire-proof plate 15 opens cylinder 1 and flame barrier, avoids cylinder 1 and contacts with the direct of flame, simultaneously because rock wool board 14 is led
Hot coefficient is small, improves the fire endurance of cylinder 1, ensure that the safety of cylinder 1.In addition, being prevented by thick fiber enhancing silicate
The cylinder 1 that fiery plate 15 surrounds, shape is upright, is convenient for secondary decoration, is also beneficial to visual appearance requirement.
As shown in Fig. 2, the flange plate 12 of cylinder 1 including intermediate plate 11 and two sides, fastener includes several being welded on the edge of a wing
On plate 12 and about the symmetrical angle steel fixing piece 2 of intermediate plate 11, several 2 sections of angle steel fixing piece are L-shaped and along flange plate 12
Length direction is equally spaced, and each one end of angle steel fixing piece 2 far from flange plate 12 contradicts with rock wool board 14 and in conflict
One end offers the first mounting hole 21, offers several second mounting holes 22, the second mounting hole on two 12 side walls of flange plate
22 are staggered with 2 position of angle steel fixing piece, to guarantee the reliability of angle steel fixing piece 2 Yu 12 weld of flange plate, correspondingly, four
Thick fiber enhances 15 side wall of silicate fire-proof plate and is equipped with several drawknots corresponding with the first mounting hole 21 and the second mounting hole 22
Rivet 23, drawknot rivet 23 pass through rock wool board 14 and thick fiber enhancing silicate fire-proof plate 15 after respectively with the first mounting hole 21 and
Second mounting hole 22 is threadedly coupled.
As shown in Fig. 2, operator need to only enhance thick fiber when actual installation thick fiber enhances silicate fire-proof plate 15
Silicate fire-proof plate 15 successively splices in 14 outside of rock wool board, and fixed, construction is then socketed by drawknot rivet 23
It is convenient and efficient, while also further improving the stability that rock wool board 14 is connect with cylinder 1.
As shown in Figure 2, it is contemplated that the material of practice of construction locality supplies situation, and rock wool board 14 replaces with foam glass, thick
Fiber reinforcement silicate fire-proof plate 15 replaces with cement pressure plate.Foam glass and cement pressure plate all have excellent anti-first
Fiery performance, secondly foam glass and all kinds of mud caking property are good so that easy for construction flexible, and cement pressure plate lightweight, it is high-strength,
Waterproof, anti-corrosion, did not only affect the appearance, but also easy to process.
As shown in Figure 3 and Figure 4, shown, further, rock wool board 14 and thick fiber enhance what silicate fire-proof plate 15 contradicted
Side offers several grooves 3, and 3 cell wall of groove is equipped with the guide plate 33 to 3 notch flare of groove obliquely, guide plate 33
Lower end is flushed with 3 notch of groove, and rock wool board 14 is bonded with air bag 31 in groove 3, air bag 31 be located above support plate and with branch
Fagging contradicts, and dry powder 32 is equipped in air bag 31, and 14 side wall of rock wool board is additionally provided with the plastic foil 34 for 3 notch of closed pockets, subtracts
The small air bag 31 when installing rock wool board 14 skids off the situation outside groove 3, while transparent materials can be used in plastic foil 34, to mention
The aesthetics on high 14 surface of rock wool board.
As shown in figure 4, open fire was before this when the thick fiber of outer layer enhancing silicate fire-proof plate 15 fails fall off in a fire
Plastic foil 34 is burnt and is broken, air bag 31 sharply expands under the high temperature action of flame, explodes, and dry powder 32 is just scattering into groove 3 therewith
Outside notch, open fire is put out;Part dry powder 32 spreads and is sprinkled upon on 14 side wall of rock wool board, change with the sliding of guide plate 33 simultaneously
Reaction is learned, and forms one layer of glassy coating under high temperature action, thus isolating oxygen, and then fire smothering.
As shown in figure 5, having resistance in addition, thick fiber enhancing 15 side wall of silicate fire-proof plate is bonded with ceramic flameproof fabric 35
The advantages that high temperature, anti-thermal shock, general fire behavior are played by ceramic flameproof fabric 35 to thick fiber enhancing silicate fire prevention
The protective action of plate 15, while ceramic flameproof fabric 35 is suitable for building materials fire-retardant decorative, improves the beauty of steel column fireproof structure
The property seen.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
