Description

Metal building fire roof system

This creation is about a metal building fireproof roof system, especially an M-shaped steel frame above the first steel plate and a barrier layer between the first steel plate and the second steel plate to reduce the building by the M-shaped steel frame. The heat conduction point of the two steel plates can effectively delay the damage speed of the building fire, and the steel beam between the wheelbases can be averaged by force, the steel consumption is reduced, the construction is simpler, and the supporting force can be directly transmitted upwards. Fire-resistant roof systems that comply with fire codes, fire resistance, wind pressure and other building codes, such as wind pressure and flame resistance, to enhance the practicality and safety of metal construction.

1 and 2, the first conventional fireproof building is provided with a first steel plate a2 above the C-shaped steel frame a1, and a U-shaped fixing base a3 above the C-shaped steel frame a1, and the U-shaped portion A square steel frame a4 is arranged inside the fixed seat a3, and a support base a5 is arranged above the square steel frame a4 to support the peak of the hidden second steel plate a6, and then laid between the first steel plate a2 and the second steel plate a6. There is a fire-retardant layer a7 (the laying process, of course, is completed one by one from bottom to top). The first conventional person has complicated construction and must be bolted down from the first steel plate a2 to the C-shaped steel frame a1 by the bolting member a8, and then the square steel frame a4 and the U-shaped fixed seat a3 are bolted by the bolting member a9. After the combination, the support member a5 and the square steel frame a4 are bolted down from the second steel plate a6 by the bolting member a10, and the square steel frame a4 can be averaged to bear the weight from the second steel plate, but the construction is carried out. The procedure is complicated and the cost is too high, and the area of the C-shaped steel frame a1, the U-shaped fixed seat a3 and the square-shaped steel frame a4 are in contact with each other, and it cannot be solved from the high temperature in the room or the outdoor high temperature from the top to the bottom. The problem of excessive heat transfer area is such that when a fire occurs in a building, the indoor high-temperature combustion flame directly contacts the first steel plate. At this time, the aforementioned C-shaped steel frame a1, U-shaped fixed seat a3 and square steel The frame a4 has too much contact area with each other. The increase in the free indoor high temperature from the bottom to the second steel plate causes the rapid collapse of the square steel frame a4 and the second steel plate, which cannot effectively delay the speed of the heat source to the square steel frame a4 and the second steel plate. The fire and flame resistance of metal buildings are limited.

3 and 4, a second conventional fireproof building is provided with a first steel plate b2 above the C-shaped steel frame b1, and a Z-shaped steel frame b3 above the first steel plate b2, and the aforementioned Z-shaped steel. A second steel plate b4 is laid over the frame b3, and of course, a fireproof layer b5 between the first steel plate b2 and the second steel frame (the laying process is of course completed one by one from bottom to top). The second conventional person uses the bolting member b6 to pass down from the lower plane of the Z-shaped steel frame b3 through the first steel plate b2 and then to the C-shaped steel frame b1, and then to the bolting member b7. The second steel plate b4 is bolted down to the upper plane of the Z-shaped steel frame b3, so that the force position of the Z-shaped steel plate is concentrated on the neutral surface of the Z-shaped steel frame b3, and the weight from the second steel plate cannot be uniformly received. Inadvertently, the Z-shaped steel frame will be deformed and reversed, and the C-shaped steel frame b1 and the first steel plate b2, the first steel plate b2 and the Z-shaped steel frame b3, the Z-shaped steel frame b3 and the second steel plate b4 are mutually The contact area is large, and it is impossible to solve the problem that the heat conduction area is transmitted from the indoor high temperature or the outdoor high temperature is transmitted from the top to the bottom. Therefore, when a fire occurs in the building, the indoor high-temperature combustion flame directly contacts the first A steel plate, at this time, because the contact area is too large, the high temperature in the free chamber will be transferred from the bottom to the second steel plate, causing the rapid collapse of the Z-shaped steel frame and the second steel plate, and the heat source cannot be effectively delayed. The speed of the Z-shaped steel frame and the second steel plate, resulting in the fireproof and flameproof effect of the metal building Restrictions.

As shown in FIG. 5, it is a third conventional fireproof building, in which a first steel plate c2 is disposed above the C-shaped steel frame c1, and a cap steel frame c3 is disposed above the first steel plate c2, and the cap steel frame c3 is used. The second steel plate c4 is laid on top, and of course, the fireproof layer c5 between the first steel plate c2 and the second steel frame c4 (the laying process is of course completed from bottom to top). The third conventional person uses the bolting component c6 to pass down from the lower plane of the cap steel frame through the first steel plate and then to the C-shaped steel frame, and then to the bolting component c7 The second steel plate is bolted down to the upper plane of the hat-shaped steel frame, so that the force position of the hat-shaped steel plate is concentrated on the middle surface, and the C-shaped steel frame is mutually pulled, and the weight from the second steel plate cannot be uniformly received. A little careless, the cap-type steel frame will be deformed, and the contact area between the C-shaped steel frame and the first steel plate, the first steel plate and the cap steel frame, the cap steel frame and the second steel plate is large, and cannot be Solve the problem of excessive heat conduction from the high temperature in the room or the high temperature from the top to the bottom. Therefore, when a fire occurs in the building, the flame of high temperature combustion in the room will directly contact the first steel plate. Because the contact area is too large, the high temperature in the free chamber will be transferred from the bottom to the second steel plate, causing rapid collapse of the cap steel frame and the second steel plate, which cannot effectively delay the heat source guiding to the cap steel frame and The speed of the second steel plate limits the fire and flame resistance of the metal building.

6 is a fourth conventional fireproof building, wherein a first steel plate d2 is disposed above the C-shaped steel frame d1, and a square steel frame d3 is disposed above the first steel plate d2, and the square steel frame d3 is formed. The second steel plate d4 is laid on the upper side, and of course, the fireproof layer d5 between the first steel plate d2 and the second steel frame d4 (the laying process is of course completed one by one from bottom to top). The fourth conventional one is that the square steel frame must be pre-punched, the processing procedure is excessive, and the cost is too high. And the bolting element d6 is passed down from the lower plane of the square steel frame through the first steel plate and then to the C-shaped steel frame, and then bolted from the second steel plate to the square shape by the bolting component d7. The upper plane of the steel frame, although the square steel frame can bear the weight from the second steel plate on average, because the C-shaped steel frame and the first steel plate, the first steel plate and the square steel frame, the square steel frame and the second steel plate are mutually The large contact area between the two cannot solve the problem of excessive heat transfer from the high temperature in the room or from the top to the outside. Therefore, when a fire occurs in a building, the flame of high temperature combustion in the room will be directly Contact with the first steel plate. At this time, because the contact area is too large, the high temperature in the free chamber will be transmitted from the bottom to the second steel plate, causing the rapid collapse of the square steel frame and the second steel plate, which cannot effectively delay. The speed at which the heat source is directed to the cap steel frame and the second steel plate limits the fire and flame resistance of the metal building.

7 is a fifth conventional fireproof building, in which a first steel plate e2 is disposed above the C-shaped steel frame e1, and a grooved steel frame e3 is disposed above the first steel plate e2, and the grooved steel frame e3 is above The second steel plate e4 is laid, and the fireproof layer e5 is placed between the first steel plate e2 and the second steel frame e4 (the laying process is of course completed one by one from bottom to top). The fifth conventional person uses the bolting element e6 to pass down from the upper plane of the trough steel frame through the first steel plate and then to the C-shaped steel frame, so that the cap portion of the embedding element e6 will be long-term. Touching the peak or groove portion of the second steel plate, when the constructor performs the laying of the second steel plate, the stepping process makes the cap portion of the plugging element e6 rub against the peak or groove portion of the second steel plate, causing secondary damage. The roof leaks.

The second steel plate f4 is laid on the upper side, and of course, the fireproof layer f5 between the first steel plate f2 and the second steel frame f4 (the laying process is of course completed one by one from bottom to top). The sixth conventional device is that the bolting element f6 is passed down from the lower plane of the C-shaped steel frame f3 through the first steel plate and then to the C-shaped steel frame f1, and then the bolting element f7 is used. The second steel plate is bolted down to the upper plane of the C-shaped steel frame f3, so that the C-shaped steel frame cannot bear the weight from the second steel plate on average. Moreover, since the contact area between the C-shaped steel frame f1 and the first steel plate, the first steel plate and the C-shaped steel frame f3, the C-shaped steel frame f3 and the second steel plate is large, it cannot be solved from the high temperature in the room. Or the problem that the outdoor heat transfer from the top to the bottom is too large. Therefore, when a fire occurs in the building, the indoor high-temperature combustion flame will directly contact the first steel plate. At this time, as the above, the contact area is too large, The increase from the indoor high temperature from the bottom to the second steel plate, causing the rapid collapse of the C-shaped steel frame f3 and the second steel plate, can not effectively delay the speed of the heat source to the C-shaped steel frame f3 and the second steel plate, resulting in Metal buildings are limited in their fire and flame resistance.

9 and 10, in a seventh conventional fireproof building, a first steel plate g2 is disposed above the C-shaped steel frame g1, and the upper portion of the C-shaped steel frame g1 is contacted with the Z-shaped steel frame g3, and then the Z A second steel plate g4 is laid above the steel frame g3 (the laying process is of course carried out one by one from bottom to top). The seventh conventional person uses the bolting element g6 to pass down from the lower plane of the Z-shaped steel frame g3 through the first steel plate and then to the C-shaped steel frame, and then to the bolting component g7 from the second The steel plate is bolted down to the upper plane of the Z-shaped steel frame, so that the Z-shaped steel frame can not bear the weight from the second steel plate on average, and is easily deformed and reversed. Moreover, because of the large contact area between the C-shaped steel frame and the first steel plate, the C-shaped steel frame and the Z-shaped steel frame, the Z-shaped steel frame and the second steel plate, it cannot be solved from the high temperature in the room or The problem that the outdoor high temperature is transmitted from top to bottom is too large. Therefore, when a fire occurs in the building, the indoor high-temperature burning flame will directly contact the first steel plate. At this time, as the above, the contact area is too large, it will increase. The high temperature from the room is transferred from the bottom to the second steel plate, causing the rapid collapse of the Z-shaped steel frame and the second steel plate, which cannot effectively delay the speed of the heat source to the Z-shaped steel frame f3 and the second steel plate, resulting in metal construction.
