Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a prefabricated UHPC and glass combination enclosure system. Background Technology

[0002] With the acceleration of urbanization, the number of old buildings in cities is constantly increasing. Because these buildings were constructed a long time ago, their facade envelope systems often have many problems, such as aging materials, poor thermal insulation, and an outdated appearance. This not only affects the aesthetics and comfort of the buildings but also increases energy consumption and maintenance costs. Traditional envelope systems mostly use materials such as brick, stone, and concrete. While these materials have a certain strength and durability, they are heavy and have poor light transmission, making it difficult to meet the modern building requirements for aesthetics, energy conservation, and environmental protection.

[0003] In recent years, ultra-high performance concrete (UHPC) and translucent curtain wall systems have gradually become important innovations in the construction field. UHPC possesses excellent mechanical properties and durability, effectively resisting external environmental erosion and extending the service life of buildings; translucent curtain wall systems offer good light transmission and aesthetic characteristics, enhancing the modernity and beauty of buildings. However, in the renovation and upgrading of existing buildings, how to effectively combine UHPC and translucent curtain wall systems to achieve a highly efficient, energy-saving, and aesthetically pleasing building envelope remains a problem that urgently needs to be solved.

[0004] Currently, while there is some research and application of UHPC and translucent curtain wall systems, most of it focuses on new buildings. Effective solutions are lacking for the renovation and upgrading of existing buildings, especially those in historical and cultural preservation areas or old buildings. Existing building envelope systems often require extensive on-site pouring and wet work during construction, resulting in long construction cycles, low efficiency, difficulty in guaranteeing quality, and significant damage to the original building structure. Furthermore, existing building envelope systems also have shortcomings in terms of thermal insulation, waterproofing, fireproofing, and maintenance, failing to meet the demands of modern buildings for high-performance building envelope systems.

[0005] Therefore, developing a prefabricated ultra-high performance concrete (UHPC) and glass enclosure system suitable for the renovation and upgrading of existing buildings has significant practical implications and broad application prospects. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a prefabricated UHPC and glass combined enclosure system.

[0007] To achieve the above-mentioned objectives, this utility model adopts the following technical solution: A prefabricated UHPC and glass combined enclosure system includes:

[0008] The exterior finish layer, composed of UHPC panels, forms a ring around the area for the installation of the translucent curtain wall layer;

[0009] A translucent curtain wall layer is installed within the area enclosed by the exterior cladding layer;

[0010] PC components are fixedly installed on the inside of the exterior finish layer for installing the light-transmitting curtain wall layer, and a waterproof and breathable membrane is provided between the PC components and the exterior finish layer;

[0011] The thermal insulation cotton is installed inside the PC component via a galvanized steel plate, and the galvanized steel plate has a groove for embedding the thermal insulation cotton.

[0012] Furthermore, the exterior finish layer is composed of a UHPC panel with a thickness of 25-35mm and a compressive strength ≥120MPa.

[0013] Furthermore, the PC component is composed of multiple PC boards spliced ​​together, with fireproof and heat-insulating strips installed between adjacent PC boards.

[0014] Furthermore, the translucent curtain wall layer is installed on the PC component through an energy-saving subframe made of thermal insulation material.

[0015] Furthermore, the exterior finish layer is fixedly connected to the PC component via connecting plates and connectors.

[0016] Furthermore, the connecting plate is connected to the outer veneer layer and the PC component by sleeve bolts, and rubber gaskets are provided between the connecting plate and the outer veneer layer and the PC component.

[0017] Furthermore, the connecting plate is made of aluminum alloy or stainless steel.

[0018] Furthermore, the translucent curtain wall layer is equipped with a self-cleaning coating, an anti-UV coating, and a heat-insulating coating.

[0019] Furthermore, the thickness of the insulation cotton should be at least 120mm.

[0020] Furthermore, the thickness of the waterproof and breathable membrane is at least 1.5 mm.

[0024] Waterproof and breathable performance: A waterproof and breathable membrane with a thickness of at least 1.5mm is installed between the outer cladding layer and the PC component to effectively prevent water vapor penetration while maintaining good breathability and preventing the internal structure from getting damp.

[0025] Fire resistance and safety performance: Fireproof insulation strips are installed between adjacent PC panels, which improves the fire resistance of the system and ensures building safety.

[0026] Aesthetics and practicality: The translucent curtain wall layer is equipped with a self-cleaning coating, an anti-UV coating, and a heat-insulating coating, which not only enhances the building's aesthetics but also improves its weather resistance and ease of maintenance.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0033] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0034] like Figure 1-3As shown, the main components of this prefabricated UHPC and glass combination enclosure system are as follows:

[0035] Ultra-high performance concrete (UHPC) panel (exterior finish layer 1): Using UHPC as the main load-bearing structure, it has excellent compressive strength, durability, impermeability, and frost resistance. The surface of the UHPC panel can be treated with various decorative finishes, such as polishing, spraying, and engraving, which not only meets structural safety requirements but also provides a high-quality appearance.

[0036] Translucent Curtain Wall Layer 2: Utilizing high-performance glass and incorporating modern architectural design concepts, this layer provides the building with light transmission and a sense of openness. The glass surface coating can be selected from products with self-cleaning, UV resistance, and heat insulation properties, improving both the building's energy efficiency and optimizing indoor lighting.

[0037] Prefabricated connection system: Utilizing prefabricated components, the various parts are connected into a whole using standardized connectors (bolts, aluminum alloy brackets (connecting plate 6), etc.). This eliminates the need for large-scale on-site pouring, enabling rapid installation and shortening the construction cycle. For example, the exterior finish layer 1 and connecting plate 6 are fixed with sleeve bolts and washers, with rubber gaskets placed between them. Similarly, PC component 3 and connecting plate 6 are also fixed with sleeve bolts and washers, with rubber gaskets placed between them as well. The energy-saving sub-frame 7 is installed on PC component 3 with screws, and the translucent curtain wall layer 2 is installed using a clamping method. The galvanized steel plate 5 is used to install the insulation cotton 4 onto PC component 3 with sleeve bolts.

[0038] Based on the above structure, this system combines galvanized steel sheet 5, thermal insulation cotton 4, PC component 3 (composed of multiple PC sheets spliced ​​together, with fireproof thermal insulation strips 31 filling the spaces between adjacent PC sheets or the fireproof thermal insulation strips 31 embedded within the PC sheets) and UHPC component 3 to form a highly integrated exterior wall system. Compared with ordinary exterior walls or simple UHPC exterior wall systems, this combined exterior wall system exhibits comprehensive advantages in several aspects, as shown in Table 1.

[0039]

[0040] The steel hangers and connectors are both parts of the prefabricated connection system.

[0041] In this system, the glass of the translucent curtain wall layer 2, as part of the facade, not only enhances the building's aesthetics and modernity but also significantly improves its light transmission. The transparency of the glass broadens the view between the interior and exterior, increasing the sense of openness of the facade. Especially in areas requiring ample natural light, the use of glass effectively improves indoor lighting conditions and saves energy. Simultaneously, the high-performance coating technology of the glass windows effectively blocks heat entry and loss, contributing to improved overall building energy efficiency. Compared to ordinary exterior walls or single UHPC exterior wall systems, the prefabricated UHPC and glass enclosure system demonstrates significant advantages in multiple aspects, including physical, chemical, mechanical, and visual aspects.

[0042] In this embodiment, the prefabricated UHPC panel of the exterior cladding layer 1 serves as an external protective layer, providing excellent weather resistance and mechanical properties, extending the building's lifespan. A multi-layered waterproofing and insulation system, including a 1.5mm waterproof layer (waterproof breathable membrane) and a 120mm insulation layer (insulation cotton 4), prevents moisture penetration and improves thermal performance, ensuring the building's waterproofing performance. The insulation cotton 4 is embedded in the galvanized steel sheet 5, ensuring its service life and waterproofing performance. The translucent curtain wall layer 2 plays a crucial role in this system, providing additional thermal insulation and enhancing the visual depth of the facade. Sealing strips are used to fill gaps between panels, providing sealing and waterproofing. Fireproof sealing increases fire resistance and prevents the spread of fire through the building envelope. To provide additional support and stability for the panels, a continuous load-bearing back-bolt system for the supporting keel can be installed, including pre-embedded steel bars and connecting sleeves in PC component 3, enhancing the overall structural stability and seismic resistance. The connection design of the glass material also follows these requirements, ensuring that it will not shift or break under wind loads and other external forces, such as the use of thermal insulation material for the energy-saving sub-frame 7. To provide a secure connection between UHPC component 3 and PC component 3, a connection layer is designed, including UHPC component 3, connectors, gaskets, sleeve bolts, and rubber gaskets, ensuring a firm connection between the glass panels and the main structure, as well as stability under wind loads and other loads. Through these detailed structural designs, the final enclosure system improves in performance, stability, and durability.

[0043] The parts of this utility model not described in detail are existing technologies, therefore, this utility model does not describe them in detail.

[0044] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0045] Although this document frequently uses terms such as exterior finishing layer 1, translucent curtain wall layer 2, PC component 3, fireproof insulation strip 31, insulation cotton 4, galvanized steel plate 5, connecting plate 6, and energy-saving sub-frame 7, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
