Description
- 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.

FIG. 1 is a cross-sectional view of aconventional building system 100, and includes a plurality ofsteel structures 101, each has a plurality of storeys. Eachsteel structure 101 includes a plurality ofhorizontal steel beams 102, a plurality ofvertical steel columns 103 and a plurality offloors 104. In the prior art, in order to enhance heat tolerance and fire-proof property of the steel structure, heat-resistant materials (like calcium silicate and asbestos) are coated onto thehorizontal steel beams 102 and thevertical steel columns 103. In addition, in order to control the spread of fire at a certain storey, said storey is provided with a fire-resistant floor 104 a that is disclosed in U.S. patent application Ser. No. 11/865,732 and that has a specific design such that the terrible part of the fire and excessive high temperature are blocked above the fire-resistant floor 104 a (i.e., at the upper storey), thereby preventing the spread of fire to the lower storey such that people living downstairs below the fire-resistant floor 104 a have sufficient time to escape from being caught in the fire. -
FIG. 2 illustrates collapse of the conventional building system under high-heat temperature. Although thehorizontal steel beams 102 and thevertical steel columns 103 are coated with heat-resistant materials, thehorizontal steel beams 102 and thevertical steel columns 103 above the fire-resistant floor 104 a are subjected to collapse due to prolong burning of the fire, which, in turn, causes breakup or breakdown of thehorizontal steel beams 102 and thevertical steel columns 103, and a sudden downfall and collision of the broken steels beams andcolumns resistant floor 104 a may cause breakup the structure of the fire-resistant floor 104 a, thereby endangering those rescue personnel below and may finally lead to total collapse of thewhole building system 100. - 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.
- The 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 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.

As illustrated, thebuilding system 300 of the present invention includes afirst building structure 301, a first fire-resistant floor 401, asecond building structure 302, a second fire-resistant floor 402 and athird building structure 302, wherein the first fire-resistant floor 401 is located between the first andsecond building structures second building structures resistant floor 402 is located between the second andthird building structures third building structures lateral side 500 in thebuilding system 300 of the present invention is determined in accordance with the ambient surrounding. The crashlateral side 500 is so named due to its location, which is close to a water pond or an empty space surrounding thebuilding system 300 of the present invention. Under such circumstances, in case of an outbreak of a fire, thebuilding system 300 of the present invention will firstly collapse toward the crash lateral side 500 (i.e., there is no vertical collapse of the building), thereby preventing injuries caused to those people living below and simultaneously reducing damage caused to the valuable property due to sidewise collapse of thebuilding system 300 of the present invention. -
FIG. 4A is a cross-sectional view of thefirst building structure 301, the first fire-resistant floor 401 and thesecond building structure 302 in thebuilding system 300 of the present invention. As shown, thefirst building structure 301 has a plurality of storeys, each storey includes a plurality of firsthorizontal beams 3011, a plurality of firstvertical support structures 3012 and a plurality offirst partition floors 3013. Each firstvertical support structure 3012 is a steel structure and is constituted by a plurality of columns or walls (W1). The first fire-resistant floor 401 is erected uprightly on a top end of thefirst building structure 301, while thesecond building structure 302 is erected uprightly on the first fire-resistant floor 401, and has a plurality of storeys. Each storey includes a plurality of secondhorizontal beams 3021, a plurality of secondvertical support structures 3022 and a plurality ofsecond partition floors 3023. Each secondvertical support structure 3022 is a steel structure, and is constituted by a plurality of columns or walls (W2). - The second vertical support structures 3022 a adjacent to the
crash lateral side 500 have a relatively low fire-resistant strength when compared to the remaining portion of the secondvertical support structures 3022 b away from thecrash lateral side 500. Under the normal condition (i.e., normal temperature), the vertical support strength of the secondvertical 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 3022 a adjacent the crash lateral side will collapse firstly toward thecrash lateral side 500 due to its relatively low fire-resistant strength in comparison to the remaining of the secondvertical support structure 3022 b due to its relatively high fire-resistant strength. - The second vertical support structures 3022 a adjacent to the
crash lateral side 500 are made from materials with a relatively low fire-resistant strength while the secondvertical support structures 3022 b away from thecrash 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 secondvertical 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 3022 a adjacent to thecrash lateral side 500 while a second heat-resistant material 602 with a relatively high fire-resistant strength is applied on the secondvertical support structure 3022 b away from thecrash 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 thebuilding 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 3022 a 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 thecrash lateral side 500 can be constructed with the heat-resistant material with a relatively low fire-resistant strength while the remaining portion of the secondvertical support structure 3022 b away from thecrash lateral side 500 can be constructed with another heat-resistant material having a relatively high fire-resistant strength. - As shown in
FIG. 4B , even though the first andsecond building structures resistant floor 401, each of the first vertical support structures has an upper surface that is used for engaging with the first fire-resistant floor 401 and that is formed with a plurality retention recesses 3014. In the same manner, each of the secondvertical support structures 3022 has a bottom surface that is to be disposed on the first fire-resistant floor 401 and that is formed with a plurality ofdownward protrusions 3024 extending respectively into the retention recesses 3014. In order to enhance binding strength between therecesses 3014 and theprotrusions 3024, a third heat-resistant material 700 is injected into the gaps between the retention recesses 3014 and thedownward protrusions 3024 in order to isolate heat conduction thereamong. After solidification of the third heat-resistant material 700, the first andsecond building structures -

Since the construction of the first andsecond building structures third building structure 303 is erected uprightly on the second fire-resistant floor 402, and has a plurality of storeys. Each storey includes a plurality of thirdhorizontal beams 3031, a plurality of thirdvertical support structures 3032 and a plurality ofthird partition floors 3033.

resistant material 602 with a relatively high fire-resistant strength is applied to the thirdvertical support structures 3032 b away from thecrash lateral side 500 while the first heat-resistant material 600 with a relatively low fire-resistant strength is applied on the thirdvertical support structures 3032 a adjacent to thecrash lateral side 500. - As shown in
FIG. 5B , even though the second andthird building structures resistant floor 402, each of the second vertical support structures has an upper surface that is used for engaging with the second fire-resistant floor 402 and that is formed with a plurality retention recesses 3025. In the same manner, each of the thirdvertical support structures 3032 has a bottom surface that is to be disposed on the second fire-resistant floor 402 and that is formed with a plurality ofdownward protrusions 3035 extending respectively into the retention recesses 3025. In order to enhance binding strength between therecesses 3025 and theprotrusions 3035, the third heat-resistant material 700 is injected into the gaps between the retention recesses 3025 and thedownward protrusions 3035 in order to isolate heat conduction thereamong. After solidification of the third heat-resistant material 700, the second andthird building structures -
FIG. 5C is a cross-sectional view of thethird building structure 303 of thebuilding system 300 of the present invention taken along the line C-C inFIG. 5A . As shown, under the normal condition (i.e., normal temperature), the vertical support strength of the thirdvertical support structures 3032 in thethird building structure 303 is uniformly distributed throughout the entire width thereof. However, in case of a breakout of fire (i.e., under high-heat temperature) or upon encountering a terrorist attack, thethird building 303 will collapse firstly toward thecrash lateral side 500. The same action will take place to thesecond building structure 302 similar to that of thethird building structure 303; a detailed description thereof is not repeated herein for the sake of brevity. - As shown in
FIG. 6 , thebuilding system 300 of the present invention is under the high-heat temperature during an outbreak of a fire. Since the vertical support structures of the lower building structures have a relatively stronger vertical support strength when compared to the vertical support structures of the upper building structures, thebuilding system 300 can maintain a firm stability under the normal condition (in the normal temperature). Note that each thirdvertical support structures 3032 is a steel structure constituted by columns or walls (structural pieces). In one embodiment of the present invention, the numeral amount of the third vertical support structures with the relatively low fire-resistant strength in the third building structure is greater than that of the second vertical support structures with the relatively low fire-resistant strength in the second building structure. Under this condition, in case of an breakout of fire (i.e., under high-heat temperature) or upon encountering a terrorist attack, it is likely that thethird building structure 303 adjacent to thecrash lateral side 500 will collapse firstly toward thecrash lateral side 500 in comparison thesecond building structure 302 located below, thereby preventing injuries caused to the rescue personnel below and simultaneously preventing an entire vertical collapse of thebuilding system 300 of the present invention. - While the invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
