1. Field of the Invention
The present invention relates to a building system, more particularly to a building system provided with a crash lateral side that is adapted to collapse first of all under high-heat temperature or in case of an outbreak of a fire.
2. Description of the Prior Art
The building technique advances ceaselessly as the city-dwelling population increases. Hence, it is in the trend to construct high-rise building structures in the modern cities. Presently, the majority of the high-rise buildings are designed in steel structures in order to shorten the construction time and in order to possess high rigidity strength and quality stability when compared to reinforced concrete buildings. The major disadvantage of these high-rise building is that it has poor heat resistant property. In the event of a fire outbreak or when encountering a terrorist attack, a fire engine is unable to extinguish the fire in addition to that the interior portion of the steel structure firstly and suddenly collapses owing to the high-heat temperature. Therefore, when designing the structure of the high-heat building, the fire-proof property (or heat tolerance) is one priority concern to be considered in addition to the tolerance strength to counter an externally applied force.
Therefore, to eliminate the disadvantages caused by the conventional building system, a novel design for a building system is necessary to reduce the impact of the collapsed storeys, which are located above the fire-resistant floor and which may collide against the fire-resistant floor due to continuation of the fire burning. Hence, the fire fighting personnel can avoid the danger of being injured during the rescue operation.
SUMMARY OF THE INVENTIONThe main object of the present invention is to provide a building system, which will collapse first of all toward a crash lateral side under high-heat temperature, thereby reducing the impact of the collapsed building part against a fire-resistant floor located underneath thereof.
The building system according to the present invention is provided with a crash lateral side which is adapted to collapse first of all under the high-heat temperature, and includes a first building structure, a first fire-resistant floor and a second building structure, wherein the first fire-resistant floor is used to isolate or prevent heat conduction between the first and second building structures. The first building structure has a plurality of storeys, each storey includes a plurality of first horizontal beams, a plurality of first vertical support structures and a plurality of partition floors. Each first vertical support structure is a steel structure and is constituted by at least one column or wall. The first fire-resistant floor is erected uprightly on a top end of the first building structure. The second building structure is erected uprightly on the first fire-resistant floor, and has a plurality of storeys. Each storey includes a plurality of second horizontal beams and a plurality of second vertical support structures. Each second vertical support structure is a steel structure and is constituted by at least one column or wall.
The distinguished feature of the present invention resides in that the second vertical support structures adjacent to the crash lateral side have a relatively low fire-resistant strength when compared to remaining portions of the second vertical support structures away from the crash lateral side such that the under the normal condition, the vertical support strength of the second vertical support structures is the same throughout the entire width of the second building structures. However, in case of a breakout of fire (or when under the high-heat temperature), the second vertical support structures adjacent to the crash lateral side collapses firstly toward the crash lateral side due to its relatively low fire-resistant strength in comparison to the remaining portion of the second vertical support structures.
In one embodiment of the present invention, the second vertical support structure adjacent to the crash lateral side has a relatively low fire-resistant strength when compared to remaining portions of said second vertical support structures away from the crash lateral side.
In another embodiment, the second vertical support structures adjacent to the crash lateral side is coated by a first heat-resistant material having a relatively low fire-resistant strength while the remaining portions thereof away from the crash lateral side are coated by a second heat-resistant material having a relatively high fire-resistant strength.
Preferably, each of the first vertical support structures has an upper surface that is used for engaging with the first fire-resistant floor and that is formed with a plurality retention recesses. In the same manner, each of the second vertical support structures has a bottom surface that is to be disposed on the first fire-resistant floor and that is formed with a plurality of downward protrusions extending respectively into the plurality retention recesses. The building system of the present invention further includes a third heat-resistant material filling the gaps between the retention recesses and the downward protrusions in order to isolate heat conduction thereamong.
Other features and advantages of this invention will become more apparent in the following detailed description of the preferred embodiments of this invention, with reference to the accompanying drawings, in which:
The second vertical support structures 3022a adjacent to the crash lateral side 500 have a relatively low fire-resistant strength when compared to the remaining portion of the second vertical support structures 3022b away from the crash lateral side 500. Under the normal condition (i.e., normal temperature), the vertical support strength of the second vertical support structures 3022 is the same throughout the entire width thereof, however in case of an breakout of fire (i.e., under high-heat temperature), the second vertical support structures 3022a adjacent the crash lateral side will collapse firstly toward the crash lateral side 500 due to its relatively low fire-resistant strength in comparison to the remaining of the second vertical support structure 3022b due to its relatively high fire-resistant strength.
The second vertical support structures 3022a adjacent to the crash lateral side 500 are made from materials with a relatively low fire-resistant strength while the second vertical support structures 3022b away from the crash lateral side 500 thereof are made from materials with a relatively high fire-resistant strength. Under the normal condition, the vertical support strength of the second vertical support structures 3022 is the same throughout the entire width. In one embodiment of the present invention, a first heat-resistant material 600 with a relatively low fire-resistant strength is applied to the second vertical support structure 3022a adjacent to the crash lateral side 500 while a second heat-resistant material 602 with a relatively high fire-resistant strength is applied on the second vertical support structure 3022b away from the crash lateral side 500. Generally speaking, a reinforced concrete building system possesses a better fire-resistant strength in comparison to a building system with steel structures. Of course, the building system with different ratio of reinforced concrete has different heat resistant capacity. The heat-resistant materials employed in the building system 300 of the present invention can also include concrete or any other heat-resistant materials.
To be more specific, not the entire part of the second vertical support structure 3022a adjacent to the crash lateral side 500 is made from the low heat-resistant materials. Note that only a certain part, such as the vertical column or wall (W2) adjacent to the crash lateral side 500 can be constructed with the heat-resistant material with a relatively low fire-resistant strength while the remaining portion of the second vertical support structure 3022b away from the crash lateral side 500 can be constructed with another heat-resistant material having a relatively high fire-resistant strength.
As shown in
Under the normal condition (i.e., normal temperature), the vertical support strength of the third vertical support structures 3032 is the same throughout the entire width thereof. The third vertical support structures 3022a adjacent to the crash lateral side 500 have a relatively low fire-resistant strength when compared to the remaining portion of the third vertical support structures 3022ba away from the crash lateral side 500.
In the same manner, the second heat-resistant material 602 with a relatively high fire-resistant strength is applied to the third vertical support structures 3032b away from the crash lateral side 500 while the first heat-resistant material 600 with a relatively low fire-resistant strength is applied on the third vertical support structures 3032a adjacent to the crash lateral side 500.
