Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge equipment technology, specifically to a vehicular glass bridge deck. Background Technology
[0002] In architectural structures, glass is highly favored due to its unique transparency and aesthetic appeal. However, traditional single-layer ordinary glass panels suffer from low out-of-plane bending strength, significant brittle fracture, and poor robustness, making it difficult to meet safety requirements and severely limiting its application in construction. While laminated glass has mitigated these shortcomings to some extent and has been widely used in high-rise buildings and critical structures, it faces new challenges in the specific scenario of bridge deck glass panels.
[0003] Unlike glass curtain walls, bridge deck glass panels, in addition to ensuring light transmission and aesthetics, must also withstand their own weight, pedestrian loads, and various loads such as wind and snow. This undoubtedly places higher demands on the safety, stability, and durability of the glass panels, and their stress analysis differs significantly from that of ordinary architectural glass. When glass is used as a load-bearing structural unit for a long period under horizontal installation conditions, both design and manufacturing face unprecedented challenges.
[0004] Currently, most common glass bridge deck designs employ a combination of multiple layers of tempered glass panels, forming a "sandwich" structure. This structure enhances the integrity of the laminated glass components to a certain extent, improves the overall load-bearing capacity, and can even retain glass fragments after the glass layers break, maintaining a certain residual load-bearing capacity. However, it is undeniable that current research on glass bridge decks primarily focuses on pedestrian bridges, mainly considering only pedestrian loads, with relatively little research on vehicular glass bridge decks. Due to the lack of corresponding design specifications, the widespread application of this structural form has encountered serious obstacles, and has even created safety hazards in some applications. Furthermore, existing design methods and specifications mainly focus on the bending performance of glass panels under uniformly distributed loads, with insufficient exploration of the bending performance of multi-layer laminated glass panels under concentrated loads, and related calculation methods are also extremely scarce.
[0005] Therefore, the current state of glass bridge decks, especially vehicular glass bridge decks, is not optimistic. Utility Model Content
[0006] The present invention aims to provide a vehicle-mounted glass bridge panel that can meet the vehicle driving load requirements while taking into account light transmittance, economy and safety.
[0007] The basic solution provided by this utility model is as follows: a vehicular glass bridge panel, including a frame and composite glass panels disposed on the frame; the frame includes multiple crossbeams and multiple longitudinal beams, and the crossbeams and longitudinal beams are connected and interlaced to form a grid-type frame; multiple composite glass panels are provided and distributed at each grid of the grid-type frame; the composite glass panels include a first glass layer, a first PVB layer, a second glass layer, a second PVB layer and a third glass layer arranged in sequence; the composite glass panels are connected to the frame by rubber supports.
[0008] Furthermore, an anchor plate is fixedly connected at the connection node between the crossbeam and the longitudinal beam.
[0009] Furthermore, the frame is mounted on a support beam; the support beam is a concrete support beam.
[0010] Furthermore, the anchor plate is fastened to the concrete support beam by bolts or chemical anchors.
[0011] Furthermore, it also includes a beam top cover plate; the beam top cover plate is disposed on the composite glass panel and is fastened to the composite glass panel by sealant.
[0012] Furthermore, the top cover plate of the beam is in the shape of an I-beam or a long strip.
[0013] Furthermore, the beam top cover plate is also securely connected to the frame.
[0014] Furthermore, the top cover plate of the beam is provided with water passage holes.
[0015] Furthermore, the height of the rubber support is 3–10 mm.
[0016] Furthermore, the first glass layer, the second glass layer, and the third glass layer are all made of light-transmitting tempered glass with a thickness of 12-14 mm; the thickness of the first PVB layer and the second PVB layer is 1.56-2 mm.
[0017] The working principle and advantages of this utility model are as follows:
[0018] This utility model discloses a glass bridge deck for vehicles, which can meet the load requirements of vehicle traffic while balancing light transmittance, economy, and safety, thus meeting the needs of practical engineering projects. The key points are:
[0019] First, this design employs a three-layer composite glass panel structure, possessing high load-bearing capacity. It effectively withstands the wheel pressure of vehicles and the dynamic effects of vehicle movement, ensuring driving stability. The middle PVB layer has excellent adhesion; even if the glass breaks under impact, the PVB layer can hold the glass fragments together, preventing them from flying and injuring people, thus improving the safety of the glass bridge. Simultaneously, the PVB layer has good transparency, not significantly affecting the light transmittance of the glass, ensuring a good visual effect for the glass bridge, allowing pedestrians to clearly appreciate the scenery below, enhancing both the bridge's practicality and aesthetics.
[0020] Secondly, the application of this solution has certain energy-saving benefits. Compared with traditional concrete driveways, this solution not only reduces the weight of the bridge, but also saves electricity during the day by utilizing the transparency of the glass panels, reducing the probability of traffic accidents caused by insufficient light. Furthermore, this solution is easier to construct, has a faster construction speed, and lower long-term operating costs.
[0021] Third, this design incorporates a beam top cover plate, secured with sealant; this provides excellent coverage for the anchor plate and concrete beam under the glass, ensuring the overall structural airtightness and enhancing the bridge's aesthetics and waterproofing.

Detailed Implementation
[0033] The following detailed explanation illustrates the specific implementation methods:
[0034] The basic implementation examples are as follows: Figure 1 As shown: A vehicular glass bridge deck includes a beam top cover plate 9, a frame, and a composite glass panel 5 disposed on the frame.
[0035] like Figure 2 and Figure 3 As shown, the skeleton is mounted on the support beam 1, which is a concrete support beam 1. The skeleton includes multiple horizontal beams 2 and multiple vertical beams 3, and the horizontal beams 2 and vertical beams 3 are connected and interlaced to form a grid-type skeleton; multiple composite glass panels 5 are provided and distributed at each grid of the grid-type skeleton. In this embodiment, both the horizontal beams 2 and the vertical beams 3 are made of rectangular steel pipes and are fixedly connected by welding or prefabrication to form a grid-type steel skeleton structure, which has strong stability. In practical applications, the support beam 1 serves as the basic load-bearing structure of the bridge. When the skeleton is set on the support beam 1, the height of the skeleton can be adjusted to create a certain slope for the foundation of the bridge panel, thereby providing an installation foundation with a drainage slope for the composite glass panel 5, which facilitates the formation of a drainage slope, avoids water accumulation, and helps ensure structural safety.
[0036] The composite glass panel 5 comprises a first glass layer 501, a first PVB layer 502, a second glass layer 503, a second PVB layer 504, and a third glass layer 505 arranged sequentially. The first glass layer 501, the second glass layer 503, and the third glass layer 505 are all made of translucent tempered glass with a thickness of 12-14 mm. The first PVB layer 502 and the second PVB layer 504 are both 1.56-2 mm thick. The composite glass panel 5 is connected to the frame via rubber supports 7. The rubber supports 7 have a height of 3-10 mm, providing sufficient elasticity and sealing to effectively buffer the vibration and deformation of the glass panel under load, reducing glass fatigue damage caused by vibration and extending the glass's service life. In this embodiment, the translucent tempered glass used is existing tempered glass that meets the relevant requirements for floor glass in the "Technical Specification for Application of Architectural Glass" (JGJ113-2015).
[0037] An anchor plate 4 is fixedly connected at the connection node between the crossbeam 2 and the longitudinal beam 3. Specifically, as shown... Figure 4 and Figure 5 As shown, the anchor plate 4 is fastened to the concrete support beam 1 by bolts 6 or chemical anchors 8. Specifically, the bolts 6 can be existing high-strength large hexagonal head bolts 6; the chemical anchors 8 are installed using the existing drill-and-weld method (i.e., the bolt is glued and fixed in the drilled hole of the concrete substrate by a special chemical adhesive to achieve anchoring), which can effectively anchor the anchor plate 4 and further strengthen the skeleton structure.
[0038] The beam top cover plate 9 is mounted on the composite glass panel 5 and is securely connected to the composite glass panel 5 using sealant 10. Specifically, the beam top cover plate 9 is arranged along the four sides of the composite glass panel 5 and is securely connected to the frame using bolts 6. The beam top cover plate 9 is I-shaped or elongated, such as... Figure 6 , Figure 7 and Figure 8 As shown. The beam top cover plate 9 further secures the position of the composite glass panel 5, ensuring the stability of the bridge deck structure. Furthermore, sealant 10 is filled between the glass layers of the composite glass panel 5 to fill the gaps between the glass layers and ensure the structure's airtightness. Specifically, the beam top cover plate 9 is made of steel or hard plastic, possessing good load-bearing capacity. The beam top cover plate 9 is provided with drainage holes 11 to facilitate drainage, such as... Figure 10 As shown.
[0039] Preferably, such as Figure 9 As shown, the upper surface of the beam top cover plate 9 is provided with anti-slip texture, which helps to prevent the vehicle from slipping.
[0040] The vehicular glass bridge panel provided in this embodiment can meet the vehicle driving load requirements and take into account light transmittance, economy and safety.
