Description

Metal building fireproof roof system

The invention relates to a fireproof roof system for a metal building, in particular to an M-shaped steel frame above the first steel plate, and a barrier layer between the first steel plate and the second steel plate, so as to reduce the size of the building through the M-shaped steel frame. The heat transfer point of the second steel plate effectively delays the damage rate caused by the fire of the building, and allows the steel beams between the wheelbases to be evenly stressed, reducing the amount of steel used, the construction is simpler, and the supporting force can be directly transmitted upwards. Wind resistance, fire resistance and other fire-resistant roof systems that comply with fire, flame, and wind resistance building regulations, to improve the practicality and safety of metal buildings.

As shown in Figures 1 and 2, it is the first conventional fire-resistant building. A first steel plate a2 is set above the C-shaped steel frame a1, and a U-shaped fixing seat a3 is set above the C-shaped steel frame a1. A square steel frame a4 is set inside the fixed seat a3, and a support a5 is arranged above the square steel frame a4 to support the peak portion 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 fireproof layer a7 (the laying construction process is of course completed from bottom to top). The first type of user is complicated in construction, and must be bolted from the first steel plate a2 to the C-shaped steel frame a1 with the bolting element a8, and the square steel frame a4 and the U-shaped fixing seat a3 with the bolting element a9. After the combination is set, the support base a5 and the square steel frame a4 are bolted down from the second steel plate a6 with the anchoring element a10. Although the square steel frame a4 can be evenly bear the weight from the second steel plate, the construction The procedure is complicated, the cost is too high, and the area where the C-shaped steel frame a1, U-shaped fixed seat a3 and the square steel frame a4 are in contact with each other is very large, and it cannot solve the problem of passing from indoor high temperature or outdoor high temperature from top to bottom The problem is that the heat transfer area is too large. Therefore, when a fire occurs in a building, the high-temperature indoor combustion flame will directly contact the first A steel plate. At this time, the aforementioned C-shaped steel frame a1, U-shaped fixing seat a3, and square steel frame a4 are too large in contact area with each other, which will increase the free indoor high temperature from bottom to top and transfer to the second steel plate, resulting in a square The rapid collapse of the profiled steel frame a4 and the second steel plate cannot effectively delay the speed of the heat source being guided to the square shaped steel frame a4 and the second steel plate, which limits the fire and flame resistance effects of metal buildings.

As shown in Figures 3 and 4, this is a second type of conventional fire-resistant building. A first steel plate b2 is provided above the C-shaped steel frame b1, and a Z-shaped steel frame b3 is provided above the first steel plate b2. A second steel plate b4 is laid over the frame b3, and of course, a fireproof layer b5 is placed between the first steel plate b2 and the second steel frame (the laying construction process is of course completed from bottom to top). The second type of person uses a bolting element b6 from the lower plane of the Z-shaped steel frame b3 to pass through the first steel plate b2 and then bolt down to the C-shaped steel frame b1. The second steel plate b4 is bolted down to the upper plane of the Z-shaped steel frame b3, so that the stress position of the Z-shaped steel plate is concentrated on the neutral surface of the Z-shaped steel frame b3, and it cannot bear the weight from the second steel plate evenly. If you are not careful, the Z-shaped steel frame will be deformed and inverted, 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, and the Z-shaped steel frame b3 and the second steel plate b4 between each other. The large contact area cannot solve the problem of excessively large heat transfer area from indoor to high temperature transmission or outdoor high temperature from top to bottom. In this way, when a fire occurs in a building, the indoor high temperature combustion flame will directly contact the first A steel plate, at this time, because the aforementioned contact area is too large, the high temperature in the free room will be transferred from the bottom to the second steel plate, resulting in the rapid collapse of the Z-shaped steel frame and the second steel plate, which cannot effectively delay the introduction of the heat source. The speed of the Z-shaped steel frame and the second steel plate causes the fire and flame resistance of metal buildings to be affected. Restrictions.

As shown in FIG. 5, it is a third type of conventional fire-resistant building. A first steel plate c2 is provided above the C-shaped steel frame c1, and a hat-shaped steel frame c3 is provided above the first steel plate c2, and the hat-shaped steel frame c3 is provided. A second steel plate c4 is laid on top, and of course, a fireproof layer c5 is placed between the first steel plate c2 and the second steel frame c4 (the laying construction process is of course completed from bottom to top). The third type of learner is a self-capped cap type c6. The lower plane of the steel frame passes through the first steel plate and is bolted down to the C-shaped steel frame, and then the second steel plate is bolted down to the upper surface of the hat-shaped steel frame with the bolting element c7, so that the hat shape The stress position of the steel plate is concentrated on its neutral surface, and it is mutually pulling with the C-shaped steel frame. It cannot even bear the weight from the second steel plate. If you are not careful, the hat-shaped steel frame will be deformed, and the C-shaped steel frame will be deformed. The contact area between the frame and the first steel plate, the first steel plate and the hat-shaped steel frame, and the hat-shaped steel frame and the second steel plate are large, and cannot be transmitted from the indoor high temperature to the top or the outdoor high temperature from the top to the bottom. The problem is that the heat transfer area is too large. In this way, when a fire occurs in a building, the high-temperature indoor combustion flame will directly contact the first steel plate. At this time, because the aforementioned contact area is too large, the indoor high temperature will increase from bottom to bottom. The upper transmission to the second steel plate caused the rapid collapse of the hat-shaped steel frame and the second steel plate, which could not effectively delay the speed of the heat source being guided to the hat-shaped steel frame and the second steel plate, which caused the fire and flame resistance of metal buildings to be limited.

As shown in FIG. 6, it is a fourth type of conventional fire-resistant building. A first steel plate d2 is provided above the C-shaped steel frame d1, and a square steel frame d3 is provided above the first steel plate d2. The second steel plate d4 is laid on the top, and of course, the fire prevention layer d5 is placed between the first steel plate d2 and the second steel frame d4 (the laying construction process is of course completed from bottom to top). In the fourth type of practice, punching is required in advance for the rectangular steel frame, and there are too many processing procedures and the cost is too high. And the bolting element d6 is passed from the lower surface of the square steel frame through the first steel plate and then bolted down to the C-shaped steel frame, and the bolting element d7 is bolted down from the second steel plate to the square shape. The upper plane of the steel frame, although the square steel frame can bear the weight from the second steel plate on average, but because the C 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 each other The large contact area between them cannot solve the problem of excessively large heat transfer area from the indoor high temperature transmission or the outdoor high temperature transmission from the top to the bottom. In this way, when a fire occurs in a building, the indoor high temperature combustion flame will directly Contact with the first steel plate, at this time, because the aforementioned contact area is too large, the high temperature in the free room will be transferred from the bottom to the second steel plate, causing the rapid collapse of the square steel frame and the second steel plate, which cannot be effectively delayed. The speed at which the heat source is guided to the hat-shaped steel frame and the second steel plate limits the fire and flame resistance effects of metal buildings.

As shown in FIG. 7, it is a fifth kind of conventional fire-resistant building. A first steel plate e2 is set above the C-shaped steel frame e1, and a channel steel frame e3 is set above the first steel plate e2. Lay the second steel plate e4, and then the fireproof layer e5 between the first steel plate e2 and the second steel frame e4 (the laying construction process is of course completed from bottom to top). The fifth kind of person uses a bolting element e6 to pass from the upper plane of the channel steel frame down through the first steel plate and then bolt down to the C-shaped steel frame, so that the cap portion of the bolting element e6 will be long-term. Touch the peak or groove of the second steel plate. When the constructor lays the second steel plate, the stepping process will easily cause the cap portion of the anchoring element e6 to rub the peak or groove of the second steel plate, causing secondary damage. , Roof leaks.

As shown in FIG. 8, it is a sixth kind of conventional fire-resistant building. A first steel plate f2 is set above the C-shaped steel frame f1, and then a C-shaped steel frame f3 is provided above the first steel plate f2, and the C-shaped steel frame f3 is provided. A second steel plate f4 is laid on top, and of course, a fire prevention layer f5 is placed between the first steel plate f2 and the second steel frame f4 (the laying construction process is of course completed from bottom to top). The sixth kind of person uses a bolting element f6 from the lower plane of the C-shaped steel frame f3 to pass through the first steel plate, and then bolts down to the C-shaped steel frame f1. 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 evenly bear the weight from the second steel plate. And because 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, and the C-shaped steel frame f3 and the second steel plate is large, it is impossible to solve the upward transmission from the indoor high temperature. Or the heat transfer area transmitted from the top down to the outdoor high temperature is too large. In this way, when a fire occurs in a building, the indoor high temperature flame will directly contact the first steel plate. At this time, as mentioned above, because the contact area is too large, the The acceleration is transmitted from the indoor high temperature to the second steel plate from bottom to top, causing the rapid collapse of the C-shaped steel frame f3 and the second steel plate, which cannot effectively delay the speed of the heat source being guided to the C-shaped steel frame f3 and the second steel plate, resulting in The fire and flame resistance effects of metal buildings are limited.

As shown in Figures 9 and 10, this is a seventh type of conventional fire-resistant building. A first steel plate g2 is set above the C-shaped steel frame g1. Then, the above-mentioned C-shaped steel frame g1 is in contact with the Z-shaped steel frame g3, and then at the aforementioned Z The second steel plate g4 is laid above the profiled steel frame g3 (the laying construction process is of course completed from bottom to top). The seventh kind of person uses the bolting element g6 from the lower plane of the Z-shaped steel frame g3 to pass through the first steel plate and then bolt down to the C-shaped steel frame, and then uses the bolting element 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 cannot evenly bear the weight from the second steel plate, and is easily deformed and inverted. Moreover, because the contact area between the C-shaped steel frame and the first steel plate, the C-shaped steel frame and the Z-shaped steel frame, and the Z-shaped steel frame and the second steel plate is large, it cannot solve the problem of upward transmission from indoor high temperature or The problem is that the heat transfer area transmitted from the top to the bottom of the outdoor high temperature is too large. In this way, when a fire occurs in a building, the indoor high temperature flame will directly contact the first steel plate. The high temperature from the room is transmitted from the bottom to the second steel plate, which causes the rapid collapse of the Z-shaped steel frame and the second steel plate. The fire and flame resistance of objects are limited.

For this reason, the inventor of this case, based on his experience in processing, manufacturing, and construction of metal building materials, specifically studies the problems of previously known technologies, which is the invention of this case.

When a fire occurs, the first steel plate in direct contact with the fire site can slow down the heat transfer to the M-shaped steel frame and the second steel plate, which can delay the collapse speed of the M-shaped steel frame and the second steel plate, and let people in the building Have to have enough time to leave the building, to achieve the fire protection and fire resistance coefficient of metal buildings, to ensure the safety of life and property of the fire-resistant roof system innovation.

A second object of the present invention is to provide a bolting element that can be locked down from the groove surface of an M-shaped steel frame into a first steel plate, so that the head of the bolting element can be buried in the M-shaped steel frame. The groove surface is more conducive to the laying operation of the second steel plate, and can avoid friction damage between the second steel plate and the head of the anchoring element.
