Description

Building system with a high temperature collapse side

The present invention relates to a building system, and more particularly to a building system having a high temperature collapse side such that the building system is poured in a direction of a high temperature collapse side at a high temperature.

With the continuous improvement of building technology and the continuous growth of the metropolitan population, the development of high-rise buildings has become an inevitable trend in the construction of modern cities. At present, the main structure of high-rise buildings is mostly steel structure design, and the steel structure is stronger than the reinforced concrete structure. It has many advantages such as light weight, labor saving and stable quality, and its biggest disadvantage is poor heat resistance. Once a high-rise building has a fire or is attacked by a terrorist bomb, not only can the fire truck be unable to be rescued, but the steel structure inside the building is also easily collapsed due to high temperature softening. Therefore, the design requirements of the high-rise building must be With load and external forces, pay more attention to fire and heat resistance.

Referring to FIG. 1 , which is a cross-sectional view of a building system of the prior art, the building system 100 includes a plurality of steel structure floors 101 , each of which includes a plurality of steel beams 102 , steel columns 103 , In order to increase the fire and heat resistance of the building system, the conventional technology usually applies refractory materials (such as calcium citrate or asbestos) to the surface of the steel beam 102 and the steel column 103.

Although the prior art applies refractory materials to the surface of the steel beam 102 and the steel column 103, if the high temperature fire continues to burn. The steel beam 102 and the steel column 103 located above the fireproof floor 104a will still collapse and fall downward. If these falling heavy objects directly impact the fireproof floor 104a, it is likely to cause structural damage of the fireproof floor 104a. The safety of personnel under fire protection floor 104a is compromised, and even the entire building system 100 is accelerated and collapsed.

Therefore, how to design a building system for the lack of the prior art, the building system can reduce the impact on the fire floor below when the upper floor collapses, to maintain the safety of the personnel under the fireproof floor and avoid the collapse of the building system.

The selection of the high temperature collapse side 500 depends on the seating position of the building system 300. Generally, If there is an open space such as a pool or a flowerbed in the surrounding environment of the building system 300, it is preferable to design the side near the open space as the high temperature collapse side 500 of the building system 300, once the building system 300 is fired due to the high temperature of the fire. When the collapse occurs, the building system 300 will dump toward the high temperature collapse side 500 to reduce the loss of personnel or property.

Referring to FIG. 4A, it is a cross-sectional view of the first building structure, the first fireproof floor panel and the second building structure of the present invention. The first building structure 301 is composed of one or more steel structure floors, each floor having a plurality of first steel beams 3011, a plurality of first vertical support structures 3012, and a plurality of first floor plates 3013, The first vertical support structure 3012 is a column or wall or an elevator wall (W1) having a steel structure; the first fireproof floor 401 is disposed above the first building structure 301; and the second building structure 302 is disposed at the first Above the fireproof floor 401, it is composed of a plurality of steel structure floors, each floor has a plurality of second steel beams 3021, a plurality of second vertical support structures 3022, and a plurality of second floor plates 3023, the second The vertical support structure 3022 is a column or wall having a steel structure or an elevator wall (W2).

The main feature of the present invention is that the temperature of the second building structure 302 is high. The second vertical support structure 3022a of the collapse side 500 is designed with a relatively low fire resistance material, while the second vertical support structure 3022b at other locations is designed with a relatively high fire resistance material, but under normal temperature conditions, The vertical support force of all of the second vertical support structures 3022 does not change. Another embodiment is to use a second vertical support structure 3022 of the same material properties and to coat (coat) a first refractory 600 on its exterior, but wrapped in a second vertical support structure 3022a on the high temperature collapse side 500. The first refractory 600 is relatively low in fire resistance. In general, concrete has better fire resistance relative to steel structures, and concrete of different compositions may have different degrees of fire resistance. The refractory material of the present invention may be selected from concrete or any material having fire resistance properties.

It should be particularly noted here that, in practice, it is not necessary to design the fire resistance of the second vertical support structure 3022a of all the high temperature collapse sides 500 to be relatively low, or to simply replace the partial high temperature collapse side 500. The fire resistance of the vertical support structure 3022a is designed to be relatively low, for example, the fire resistance of one of the columns, a wall or the elevator wall (W2) of the high temperature collapse side 500 is designed to be relatively low, while the fire resistance at all other locations is the same. .

Referring to FIG. 4B, although the first building structure 301 and the second building structure 302 are blocked by the first fireproof floor 401, the strength transmission between the two building structures 301 and 401 is ensured. a surface of the first vertical support structure 3012 combined with the first fireproof floor 401 is provided with a coupling groove 3014, and the second vertical support structure 3022 is combined with the first fireproof floor 401. A coupling protrusion 3024 is inserted, and the coupling protrusion 3024 is inserted into the coupling groove 3014, and a second refractory material 700 is used to fix the two and block the heat transfer between the two, so that the upper portion The combination of the second building structure 302 and the first building structure 301 below will be more stable and more resistant to horizontal forces such as wind or seismic forces.

Referring to FIG. 5A, it is a cross-sectional view of the second building structure, the second fireproof floor panel, and the third building structure of the present invention. The second building structure 302 is composed of a plurality of steel structure floors, each floor having a plurality of second steel beams 3021, a plurality of second vertical support structures 3022, and a plurality of second floor plates 3023, the second The vertical support structure 3022 is a column or wall or an elevator wall (W2) having a steel structure; the second fireproof floor 402 is disposed above the second building structure 302; the third building structure 303 is disposed on the second fireproof floor Above 402, it is composed of a plurality of steel structure floors, each floor has a plurality of third steel beams 3031, a plurality of third vertical support structures 3032, and a plurality of third floor plates 3033, the third vertical support Structure 3032 is a column or wall with steel structure or an elevator wall (W3).

In order for the building system 300 to be in a normal temperature state, the vertical support forces of all of the third vertical support structures 3032 do not change, and in order to cause the building system 300 to be in a high temperature state, the third vertical support structure on the high temperature collapse side 500 The vertical support force of 3032a is lower than the vertical support force of the third vertical support structure 3032b at other locations, causing the third building structure 303 to tip down toward the high temperature collapse side 500. The design of the third building structure 303 of the present invention is similar to the design of the second building structure 302. The main features include: the third vertical supporting structure 3032a on the high temperature collapse side 500 of the third building structure 303 is relatively low in fire resistance. The material design, while the third vertical support structure 3032b at other positions is designed with a relatively high fire resistance material, but under normal temperature conditions, the vertical support force of all the third vertical support structures 3032 does not change; Or adopting a third vertical support structure 3032 of the same material property and coating (coating) a first refractory material 600 on the outer surface thereof, but the first vertical support structure 3032a of the high temperature collapse side 500 is coated with the first The refractory 600 has a relatively low fire resistance.

Referring to FIG. 5B, although the second building structure 302 and the third building structure 303 are blocked by the second fireproof floor panel 402, in order to ensure the stable transmission of power between the two building structures 302, 303 a combination groove 3025 is disposed on the surface of the second vertical support structure 3022 and the second fireproof floor 402, and the third vertical support structure 3032 is combined with the second fireproof floor 402. The lower surface is provided with a coupling protrusion 3035. The coupling protrusion 3035 is inserted into the coupling groove 3025, and the second refractory material 700 is used to fix the two and block the heat transfer between the two. The combination of the upper third building structure 303 and the lower second building structure 302 will be more stable and more resistant to horizontal forces such as wind or seismic forces.

Referring to FIG. 5C, it is a cross-sectional view of FIG. 5A in the C-C' direction, which is a cross-sectional view of the third building structure 303 in the horizontal direction, and the third building structure 303 is known from the figure. The three vertical support structures 3032 are symmetrically distributed, and the normal vertical support force of the third building structure 303 is also symmetrically distributed at normal temperatures. However, in the high temperature state, the vertical supporting force of the third vertical supporting structure 3032a near the high temperature collapse side 600 is relatively low (for the reason as described above), and therefore, in the event of a fire or an explosion attack, the third building structure 303 will collapse toward a high temperature. Side 600 is dumped. Similarly, the second building structure 302 is also designed to have a similar dumping phenomenon as the third building structure 303, and will not be described again.

The number of structures 3022 is small such that the extent to which the third building structure 303 is dumped at the high temperature collapse side 500 is greater when a fire occurs, while the second building structure 302 is less inclined at the high temperature collapse side 500 to maintain the underlying building structure. Integrity and reduce the loss of life and property when a fire occurs.
