Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel structure, specifically relating to green building energy-saving and fireproof steel structure. Background Technology
[0002] Large-scale green building energy-saving and fireproof steel structure refers to a building system that uses steel structures that meet energy-saving and environmental protection requirements and have fire-resistant properties when designing and constructing green buildings. Steel structures are widely used in modern buildings due to their advantages such as high strength, light weight, and short construction period.
[0003] Traditional fire protection measures for steel structures often involve spraying specific fire-retardant coatings onto the surface of I-beams to isolate them from high temperatures during a fire. However, this single-coat insulation method often results in the coating peeling off due to prolonged exposure to high temperatures or lack of maintenance. Furthermore, steel structures are prone to deformation and instability at high temperatures due to the high thermal conductivity of metals, thus leading to deficiencies in the fire resistance of existing steel structures.
[0004] Therefore, in response to the problem that existing steel structures are prone to deformation and instability during fires, a green building energy-saving and fire-resistant steel structure is developed. By adding a multi-layer internal fireproof isolation structure to the steel structure, the thermal insulation of the I-beams is guaranteed in the event of a fire, so as to prevent them from undergoing large deformation or instability.

Detailed Implementation
[0022] Green building energy-saving and fire-resistant steel structures refer to building systems that utilize steel structures that meet energy-saving and environmental protection requirements while possessing fire-resistant properties during the design and construction of green buildings. Steel structures are widely used in modern architecture due to their high strength, lightweight, and short construction period. In green buildings, steel structures not only need to meet structural strength and safety requirements but also need to consider energy efficiency, environmental friendliness, and fire resistance.
[0023] 1. Green building and energy conservation
[0024] Green building emphasizes minimizing negative environmental impacts and maximizing resource efficiency throughout the building's entire lifecycle. Energy conservation is a crucial component of green building, achieved through several key aspects:
[0025] Material Selection: Low-energy-consumption and renewable materials are used to reduce resource waste. Design Optimization: Energy consumption is reduced through reasonable building layout, window design, and shading. Intelligent System: Energy management is carried out using an intelligent control system to improve building energy efficiency. Steel structures themselves have a good strength-to-weight ratio; using steel in buildings can reduce material usage, lighten the building's weight, and improve the building's energy-saving performance. At the same time, the prefabrication and modular design of steel structures can also improve construction efficiency and shorten the construction cycle, thereby reducing energy consumption during the construction process.
[0026] 2. Fire resistance
[0027] Due to the high thermal conductivity of metals, steel structures are prone to deformation and instability at high temperatures, making fire resistance particularly important. In green buildings, the fire protection design of steel structures mainly includes the following aspects: Fire-retardant coatings: Fire-retardant coatings can be applied to the surface of steel structures to increase their fire resistance. Common fire-retardant coatings include intumescent coatings and water-based coatings. These coatings expand during a fire, forming an insulating layer and slowing down the temperature rise of the steel. Fire-resistant protective layers: Steel structures can also be covered with materials such as gypsum board and firebricks to improve their fire resistance. Fire-resistant isolation design: Fire-resistant partitions and fire doors can be used inside the building to isolate the spread of fire and protect the structural safety. Fire-resistant steel: Some steels undergo special treatments to improve their high-temperature resistance and delay yielding and instability.
[0028] 3. Advantages of steel structures
[0029] High strength and stability: Steel structures have high strength and can withstand large loads, ensuring the stability of the building. Recyclable: Steel is a recyclable and reusable material, meeting the environmental protection requirements of green buildings. Fast construction: Steel structures have a high degree of prefabrication, making on-site installation convenient, which can shorten the construction cycle and reduce resource waste. Strong seismic resistance: Steel structures have good toughness and can resist a certain degree of vibration, making them suitable for earthquake-prone areas.
[0030] 4. Future Trends in Integrating Green Buildings with Steel Structures
[0031] With the growing acceptance of sustainable building concepts, energy conservation, environmental protection, and safety are increasingly emphasized in the design and construction of green buildings. The application of steel structures in green buildings will continue to grow, especially in high-rise buildings, large-span buildings, and industrial buildings. Future steel structures will not only be optimized in terms of fire resistance and energy efficiency, but will also incorporate intelligent technologies to achieve efficient energy management and environmental friendliness.
[0032] Overall, green building energy-saving and fireproof steel structures have significant application value in meeting the modern building's needs for safety, environmental protection, and energy conservation. Furthermore, with technological advancements, their application scope and effectiveness will continue to expand.
[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0034] Please see Figures 1-5 This utility model provides an embodiment of a green building energy-saving and fireproof steel structure, including a gypsum shell 1 and an I-beam 2, as well as fireproof frame 3, fireproof frame 4, expansion plate 6, fireproof board 9 and fireproof cotton 10. The expansion plate 6 is made of expanded silicate material, the fireproof cotton 10 is expanded type, and the fireproof board 9 is made of expanded graphite material. The front and rear ends of the fireproof frame 4 are provided with a first groove 7, and the expansion plate 6 is installed in the first groove 7. The ends of the fireproof frame 4 that are close to each other are fixed with equally spaced extension frames 8, and the ends of the fireproof frame 3 that are far apart from each other are fixed with equally spaced limiting frames 11, and the fireproof cotton 10 is installed in the limiting frames 11.
[0035] The expansion plates 6 distributed on the upper and lower sides of the I-shaped steel 2, the fireproof plates 9 distributed on the inner walls of the left and right sides of the I-shaped steel 2, and the fireproof cotton 10 can expand when heated in the event of a fire to fill the gap between the gypsum shell 1 and the I-shaped steel 2. The expansion material forms an internal fireproof layer to isolate the I-shaped steel 2 from the high temperature outside. The fireproof frame 4 can provide certain limiting support for the inner walls of the left and right sides of the I-shaped steel 2, thereby improving its support capacity and load-bearing effect.
[0036] Please see Figures 3-4In this embodiment, fireproof frames 4 are fitted onto the outer walls of the front and rear ends of the I-shaped steel 2. The fireproof frames 4 are divided into two sets symmetrically distributed front and rear. In use, the two sets of fireproof frames 4 can provide auxiliary reinforcement to the front and rear ends of the I-shaped steel 2 by wrapping it, thereby improving its strength. The ends of the extension frames 8 that are close to each other are attached to the inner walls of the center of the left and right ends of the I-shaped steel 2, and fireproof plates 9 are installed at the ends of the extension frames 8 that are far apart from each other. In use, the extension frames 8 can further enhance the effect of the fireproof frames 4 in wrapping the I-shaped steel 2 for auxiliary support. The upper and lower ends of the fireproof frames 4 are provided with symmetrically distributed limiting grooves 5, and fireproof frame plates 3 are installed in the limiting grooves 5. During use, the limiting groove 5 can position the fireproof frame plate 3 and evenly distribute the pressure on the fireproof frame plate 3 to the I-shaped steel 2. The upper and lower ends of the fireproof frame plate 3 are on the same plane as the upper and lower ends of the I-shaped steel 2, and the upper and lower ends of the fireproof frame 4 are on the same plane as the upper and lower ends of the I-shaped steel 2. During use, the fireproof frame plate 3 and the fireproof frame 4 of the same length can provide maximum fire protection for the four sides of the I-shaped steel 2. The fireproof frame plate 3 and the fireproof plate 9 are symmetrically distributed from left to right. During use, the symmetrically distributed fireproof frame plate 3 and the fireproof plate 9 can provide multi-layer isolation fire protection for the left and right ends of the I-shaped steel 2.
[0037] Please see Figures 3-5 In this embodiment, the gypsum shell 1 is fitted onto the outer wall of the fireproof frame 4. The inner walls of the front and rear ends of the gypsum shell 1 are provided with second grooves 12. The inner wall of the second groove 12 is attached to the outer wall of the expansion plate 6. In use, the gypsum shell 1 can provide a certain flame-retardant effect against open flames in the outside world to prevent the spread of fire.
[0038] In the event of a fire, the high temperature will cause the expansion plates 6 distributed on the upper and lower sides of the I-shaped steel 2 and the fireproof plates 9 and fireproof cotton 10 distributed on the inner walls of the left and right sides of the I-shaped steel 2 to expand thermally, thereby quickly filling the gap between the gypsum shell 1 and the I-shaped steel 2. The expansion material forms an inner fireproof layer to wrap and protect the outer wall of the I-shaped steel 2, thus isolating it from the high temperature from the outside.
[0039] Through the above steps, the expansion plates 6 distributed on the upper and lower sides of the I-shaped steel 2, the fireproof plates 9 distributed on the inner walls of the left and right sides of the I-shaped steel 2, and the fireproof cotton 10 can expand when heated in the event of a fire, filling the gap between the gypsum shell 1 and the I-shaped steel 2. The expansion material forms an internal fireproof layer to isolate the I-shaped steel 2 from the high external temperature, thus solving the problem that existing steel structures are prone to deformation and instability in the event of a fire.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
