The floor slabs have RC slabs laid on the decks. The external walls each have an RC curb formed on the RC slab by means of casting, two steel C profiles, one of which is installed on the RC curb with an opening thereof facing upward, and the other of which is mounted on the deck with an opening thereof facing downward; and an outer wall panel and an inner wall panel, attached to opposite sides of the RC curb and the two steel C profiles, respectively, so that a hollow space is formed between the outer wall panel and the inner wall panel. Thereby the external walls have a two-layer structure and are affixed directly to the floor slabs.

Description

Structure of steel building shell

The invention relates to the structure of a steel structure building shell. In particular, the outer wall of the building is directly installed on the building floor, so that the building floor effectively separates the upper/lower floor space, and has better sound insulation, heat insulation, waterproofing, etc. Steel structure buildings are better suited to the needs of residential buildings.

Early residential buildings in Taiwan were mainly made of bricks. After reinforced concrete technology was introduced to Taiwan and costs were reduced, residential buildings were mostly made of reinforced concrete. Later, with Taiwan's economic development and high population density, due to the high cost of land, the demand for super high-rise buildings mainly composed of steel structures increased. Not only in commercial buildings, but also in residential buildings, there are more and more super high-rise buildings with steel structures. Among them, according to statistics, residential construction in Taiwan accounts for more than 90% and is the bulk of the construction industry.

Overall, Taiwanese architecture covers three structural systems: RC structure (reinforced concrete), SS structure (steel frame structure) and SRC structure (steel frame reinforced concrete).

RC structure (reinforced concrete) uses formwork as a structural model, then ties steel bars and pours concrete. It uses the tensile properties of steel bars and the compressive properties of concrete to support the structural strength. This is also the most common construction method in Taiwan's construction industry, accounting for 10% of the total. More than 90% of Taiwan's buildings (including residential buildings and commercial buildings) (mid- to low-rise 5 to 15-story houses, almost 100%). Over the past 40 years, residential buildings in Taiwan have been constructed using a large number of RC structures (reinforced concrete). Due to frequent earthquakes in Taiwan, when the grouting during RC construction happens to encounter an earthquake, the holding force of the concrete and steel bars will be greatly reduced, seriously affecting the structural strength. Also due to the climate, reinforced concrete structures are often exposed to high temperature and humidity. Concrete that has been exposed to high humidity and high temperature for a long time will High moisture will be generated inside, causing the internal hydration products to be dissolved, resulting in an increase in the total porosity or connectivity of the concrete. When the concrete is exposed to carbon dioxide in the air for a long time, the concrete will be neutralized (or carbonized), and the steel bars will also increase. The probability of corrosion will lead to expansion due to corrosion, causing the concrete to crack and peel (swell), and the appearance will begin to appear white and bricks will fall off, resulting in a reduction in the bearing capacity of the concrete structure and loss of the structure's earthquake resistance, directly endangering residential use and safety. . Therefore, the service life of RC structure (reinforced concrete) buildings is short, about 30 to 50 years. Today, most of the RC buildings built in large numbers due to the rapid economic development and population growth in Taiwan in the early days have entered the end of their life cycles. In order to maintain residential buildings, Most of the security measures are in full swing, but reconstruction of residential buildings is more difficult. As a result, many people still live in RC houses with structural risks.

SS structure (steel frame structure) uses steel frames as a building structure. SS structure has better toughness and thus achieves better earthquake resistance. It is usually used in super high-rise buildings because super high-rise buildings are subject to considerable earthquake forces. Large, the requirements for earthquake resistance are relatively high. Taiwan is in an earthquake zone, so for buildings with more than 30 floors, it is stipulated that the "toughness design" of the regulations must be met. When using RC structures, in order to meet the "toughness design", the cross-section dimensions of the columns and beams will be too large, which will affect the Indoor space (especially basement parking spaces and 1st to 8th floor sections are in greater demand), so SS structures are mostly used in commercial buildings or public buildings (departments, restaurants, long-span stadiums, factories). However, the SS structure is susceptible to wind force causing the building to shake. This part can resist the displacement of the building through diagonal braces and seismic walls. The displacement can be controlled to 2/1000, which is lower than that of reinforced concrete. , which greatly complements the problems of SS structure in this aspect.

SRC structure (Steel Reinforced Concrete) is a basic structure composed of steel columns and steel beams. The steel frames are then covered with steel bars. After the formwork is assembled, concrete is poured to complete the construction of beams, columns and floors. The existence of the SRC structure hopes to combine the compression resistance of the RC structure (increasing rigidity to avoid earthquake forces and wind forces causing the building to sway) and the seismic resistance of the SS structure (toughness helps resist earthquake forces) to achieve residential comfort requirements. However, in fact, the design strength of SRC structures is the same as that of RC structures. Because the reinforced concrete cladding of the structure also has no energy dissipation mechanism, the SRC structure causes duplication of construction (steel columns and beams + RC cladding), increased construction costs, and longer work processes. Slow, time-consuming and labor-intensive.

In addition, due to population growth and industrial development, the large-scale production of greenhouse gases is gradually degrading the human living environment. Professor Lin Xiande of the Department of Architecture of National Cheng Kung University published in the sustainable environment chapter of Today’s Weekly on December 15, 2021: United Nations Environmental Planning (UNEP) The 2020 report pointed out that the construction industry emitted 35% of the world's total energy consumption and 38% of the total greenhouse gases in 2019, which is higher than the total emissions of the industrial sector and transportation. Therefore, the construction industry Energy conservation and emission reduction are important indicators for countries to achieve net-zero emissions to control greenhouse gas warming. Therefore, in order to control greenhouse gas emissions, countries have begun to develop low-carbon "green buildings" and formulate relevant regulations, trying to improve the current construction industry from aspects such as design, construction, operation and use, and dismantling (recycling or waste disposal). my country's current "Nine Evaluation Index System for Green Buildings (EEWH)" includes biodiversity, greening amount, base water retention, daily energy saving, carbon dioxide reduction, waste reduction, indoor environment, water resources and sewage and garbage improvement, etc. evaluation indicators. Taiwan's National Development Council officially announced the "Taiwan 2050 Net-Zero Emission Pathway and Strategy General Description" in March 2022, requiring 100% of new buildings and more than 85% of existing buildings to be gradually transformed into near-zero emissions before 2050. Zero carbon buildings.

Among the aforementioned RC structure (reinforced concrete), SS structure (steel frame structure) and SRC structure (steel frame reinforced concrete), the carbon emissions of the RC structure building during the construction process are more than twice that of the SS structure, and the RC structure due to its service life It is difficult to recycle and reuse concrete after being demolished due to short or other factors. When the steel structure of the SS structure is demolished due to necessity, most of the steel can be recycled and reused. Therefore, the SS structure has the advantages of lower energy consumption and lower carbon emissions. However, The construction cost of SS structures is about 30% higher than that of RC structures. Therefore, except for super high-rise buildings, most of the buildings on the market are still dominated by RC structures. In Taiwan, super high-rise residential buildings except SS structures In addition, SRC structures are still widely used. The main reasons are: 1. The interface details of the reinforced concrete structure of the wet construction method are easier than the dry construction method of steel frames and steel iron parts. 2. It is mistakenly believed that steel column and steel beam structures plus RC protection can achieve fire prevention, waterproofing, rust prevention, sound insulation, weather resistance... and other properties once and for all; in fact, in terms of environmental protection data, the SRC structure is the worst of the three, and the structure There are no advantages in terms of stress or engineering construction procedures, but the disadvantages of concrete deterioration exist as with RC structures, and the seismic performance level of SS structures cannot be achieved.

In fact, although the construction cost of SS structures is higher than that of RC structures, the theoretical service life of steel structure buildings can be up to 100 years, so the use cost of SS structure buildings will not be higher than that of RC structure buildings. However, when Mr. Huang Yanzhong published a paper on "Evaluation and Establishment of Electronic Procurement System in the Steel Industry", he pointed out that "according to statistics from the OECD (Organization for Economic Co-Operation and Development), the construction industry is one of the largest industries in the world, accounting for 13% of global GDP. .4%, about 7.5 trillion U.S. dollars (WSA 2013). At the same time, the steel consumption in the construction industry accounts for more than 50% of the world's steel production... The steel structures used in construction in Taiwan only accounted for about 10% of Taiwan's total steel production in 2013. There is still a considerable gap between the 5.0% and 7.5% of the 34 million metric tons and the 30% to 40% (2010) of advanced countries such as Europe, the United States and Japan (even as high as more than 85% in the Nordic countries). Since the 921 earthquake, considering the residential Due to factors such as earthquake control functional requirements and safety, the proportion of steel structures used in residential and non-residential buildings has increased significantly. The world has increasingly higher requirements for carbon reduction and sustainability. The use of steel is not only more effective in reducing carbon emissions than Concrete is obviously effective. At the same time, the recycling rate of steel exceeds 90%, making it the best choice for environmentally sustainable building materials." Therefore, Taiwan’s steel structure buildings still have a lot of room for growth.

Referring to Figures 8 to 10, most of the exterior walls of traditional SS structure buildings adopt curtain walls 10. The curtain walls 10 are light in weight and are in the form of modular units. The construction and assembly are quick. The assembly method is to combine the curtain walls 10 with each other. The component 20 is fixed on the steel structure, which includes H steel beams 30 and DECK steel floor slabs. 40. The RC floor slab 50 is laid on the DECK steel-bearing floor slab 40, and the DECK steel-bearing floor slab 40 and the RC floor slab 50 are used as the building floor slab, so that the curtain wall 10 is hung outside the building floor slab through the coupling member 20.

SS structure buildings have the following problems that need to be overcome in order to reduce the cost of SS structure buildings and meet higher comfort requirements in residential spaces:

1. Inter-story displacement: The curtain wall 10 is calculated based on the overall building height. Each group of curtain walls 10 needs to review the displacement of the total height. Therefore, the inter-story displacement of each group of curtain walls 10 affects each other and is relatively complex.

2. Fireproof filling: The assembly method of the curtain wall 10 will leave a gap between the curtain wall 10 and the building floor. Therefore, it is necessary to set a fireproof interlayer plug 60 in the gap between the curtain wall 10 and the building floor, and apply it on the building floor. Sealing panels to block the space above/below the building floor.

3. Internal and external waterproofing: In commercial buildings, pipe rooms, elevators, toilets, pantries, and kitchen areas are all centrally located, often called "Service Cores". These "water areas" that use water are concentrated , it is easy to avoid the gap between the curtain wall 10 and the building floor, and the water supply and drainage pipes are easy to install. However, residential buildings have many "water area" requirements, such as toilets, bathrooms, balconies, kitchens, etc. These spaces are scattered and arranged. Water supply and drainage pipes are not easy to configure, and the waterproofing of upper/lower floors requires special measures.

4. Sound insulation/heat insulation: If the curtain exterior wall 10 is made of metal, RC concrete panels or glass curtains, it is necessary to determine whether the material properties of the curtain wall 10 meet the sound insulation requirements, or additional backing materials should be used to enhance sound insulation and heat insulation. Therefore, the material itself can easily cause solid sound transmission or heat conduction.

5. Exterior wall maintenance: Since the curtain wall 10 needs to rely on its own material characteristics for sound insulation or the backing material to reinforce the sound insulation or heat insulation, the surface of the curtain wall 1 is difficult to maintain and update.

According to the above explanation, since residential space requires higher comfort requirements, it has higher performance requirements in terms of waterproofing, airtightness, sound insulation, and earthquake isolation. Therefore, the cost of SS structure residential buildings will be greatly increased, so SS structures are rarely used in Low-rise residences.

SS structures can extend the service life of buildings and comply with green building requirements. Residential buildings account for more than 90% of all buildings in Taiwan. In order to make SS structures more in line with the needs of residential buildings, they can increase the service life of residential buildings and help achieve net zero. For carbon emissions, the present invention proposes a structure of a steel structure building shell, which includes: a steel structure building main body, including H steel beams and DECK steel floor-bearing plates, and the DECK steel floor-bearing plates are assembled on the H steel beams. The building floor slabs include RC floor slabs laid on the DECK steel bearing floor slabs, and the DECK steel bearing floor slabs and the RC floor slabs serve as the building floor slabs. The exterior wall of the building includes: RC water-stopping pier, which is poured and molded on the RC floor; two C-shaped steels, one of which is set on the RC water-stopping pier with the opening facing upward, and the other is set on the DECK steel floor-bearing plate. with the opening facing downward; the exterior wall panel and the interior wall panel are attached to the opposite sides of the RC water stop pier and the two C-shaped steels, forming a hollow space between the exterior wall panel and the interior wall panel; thereby The building exterior wall is made into a double-layer structure, and the building exterior wall is directly arranged on the building floor.

Furthermore, two long-shaped rock wools are respectively provided on the two C-shaped steels and filled in the hollow space. The two long-shaped rock wools extend along the height direction of the building exterior wall. Furthermore, the elongated rock wool is arranged in the exterior wall of the building in an S-shaped bend in the height direction.

Further, the H-steel beam is arranged on the indoor side adjacent to the interior wall panel, and the exterior wall panel is attached to the RC water-stop pier, the two C-shaped steels and the rectangular rock from the end of the building floor. On cotton. Go further Step 1: Set a transverse aluminum extrusion between two adjacent exterior wall panels in the height direction, and fill silicone between the transverse aluminum extrusion and the two exterior wall panels.

Further, the H steel beam is arranged on the indoor side adjacent to the interior wall panel, and the building floor protrudes out of the outdoor side outside the exterior wall panel.

Further, the H steel beam is arranged on the outdoor side adjacent to the exterior wall panel. Furthermore, the H steel beam is equipped with galvanized square tubes around its periphery and is covered with concrete slabs on the outermost side.

Further, elastic cement is filled in the assembly gaps of the exterior wall panels.

Furthermore, the entire building is sprayed with a waterproof layer on the exterior wall panels, and further coated with natural paint.

Based on the above characteristics, the following effects can be achieved:

1. Inter-story displacement: The building exterior wall of the present invention is directly installed on the building floor. The building floor can completely separate the upper/lower floor space. The inter-story displacement is calculated based on the height of the current floor, such as the height of the current floor. is 3.2 meters, and the deformation of the entire building is 1/1000, then the deformation between floors is 3.2 meters multiplied by 1/1000, which is equal to 3.2 centimeters, so the deformation between floors is extremely small.

2. Fireproof filling: The building exterior wall of the present invention is directly installed on the building floor. The building floor can completely separate the upper/lower floor space. Therefore, there is no need to install a fireproof interlayer plug between the building exterior wall and the building floor, and the building floor itself is As a fireproof structural layer, there is no need to install indoor sealing boards or covers.

3. Internal and external waterproofing: The building exterior wall of the present invention is directly installed on the building floor. The building floor can completely separate the upper/lower floor space. Therefore, the building floor itself is a good water-cutting layer. It can be used in toilets and toilets of residential buildings. Scattered "water areas" such as bathrooms, balconies, and kitchens are easier to install water supply and drainage pipes.

4. Sound insulation/heat insulation: The building exterior wall of the present invention is a double-layer structure assembled from exterior wall panels and interior wall panels. There is a hollow space between the exterior wall panels and the interior wall panels, or the hollow space is further filled with elongated Rock wool is equivalent to an extra layer of air blocking noise and heat transfer, so it has better sound insulation and heat insulation.

5. Exterior wall maintenance: The exterior wall of the building of the present invention uses aluminum extrusion to rationally fill the floor joints. The quantity of silicone is small, so the maintenance is better and the cost is less.

Referring to the first and third figures, the steel structure building body A includes an H steel beam 1 and a DECK steel floor slab 2. The DECK steel floor slab 2 is assembled on the H steel beam 1. The building floor slab B includes an RC floor slab 3 laid on the DECK steel bearing floor slab 2 , and the DECK steel bearing floor slab 2 and the RC floor slab 3 serve as the building floor slab B. The building exterior wall C includes: RC water-stop pier 4, poured and formed on the RC floor slab 3; two C-shaped steel 5, one of which is set on the RC water-stop pier 4 with the opening facing upward, and the other is set On the DECK steel floor slab 2 with the opening facing downwards; the exterior wall panel 61 and the interior wall panel 62 are attached to the opposite sides of the RC water stop pier 4 and the two C-shaped steel 5, and on the exterior wall panel 61 A hollow space S is formed between the inner wall panel 62 and the inner wall panel 62; thereby making the building exterior wall C have a double-layer structure, and allowing the building exterior wall C to be directly installed on the building floor slab B, so that the building floor slab B can be completely separated. The upper/lower floor space becomes a good water/sound insulation/heat insulation layer between the upper/lower floors, and the elastic cement 63 can be further filled in the assembly gaps of the exterior wall panels 61 to improve the indoor and outdoor space.
