Description

Technical Field

[0001] This utility model relates to the field of building materials and sports facilities technology, specifically a hyperbolic component for the curved surface of a UHPC speed skating stadium. Background Technology

[0002] In the construction of speed skating stadiums, the design and construction of curves has always been a key technical challenge. Traditional concrete or asphalt materials often fail to achieve ideal curvature matching and durability when constructing curves, leading to instability and safety hazards for athletes during skating. Furthermore, these materials are susceptible to environmental factors such as temperature and humidity changes, causing surface cracking and deformation, which in turn affects the smooth running of the competition and the athletes' performance.

[0003] To overcome the aforementioned technical challenges and improve the performance of the curves in speed skating stadiums, ultra-high performance concrete (UHPC) has been gradually introduced into the construction of speed skating stadiums as a new type of building material in recent years. UHPC has extremely high compressive, tensile, and flexural strength and durability, and can effectively resist the erosion and damage of environmental factors, providing more reliable and stable support for the curves of speed skating stadiums.

[0004] However, simply using UHPC material is insufficient to completely solve the technical challenges of curved surfaces. Due to the complex curvature variations of speed skating stadium curves, traditional flat or single-curved sheets cannot accurately match their curvature, resulting in uneven surfaces that negatively impact the skating experience and safety for athletes. Therefore, it is necessary to develop a hyperbolic component capable of precisely matching the curvature of speed skating stadium curves. Utility Model Content

[0005] The purpose of this invention is to provide a hyperbolic component for the curve surface of a speed skating stadium using UHPC material. By employing UHPC material and a hyperbolic surface design, the strength and durability of the component are improved, and it precisely matches the curvature of the speed skating stadium's curve surface, providing athletes with a stable and safe skating surface. Furthermore, this invention simplifies the construction process, improves construction efficiency, and reduces construction costs through modular design and optimized anchoring mechanisms.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hyperbolic component for the curved surface of a UHPC speed skating stadium includes a UHPC hyperbolic panel. Both sides of the UHPC hyperbolic panel are curved surfaces with the same curvature direction. A lower support beam is fixedly installed at the bottom of the UHPC hyperbolic panel. An end positioning block is fixedly installed at one end of the UHPC hyperbolic panel, and an end positioning groove is provided at the other end of the UHPC hyperbolic panel. The lower support beam is inverted T-shaped, and anchoring holes are symmetrically arranged on both sides of the lower support beam. An anchoring mechanism is fixedly installed inside the anchoring holes. The UHPC hyperbolic panel and the lower support beam are an integral structure with a reinforcing mesh pre-embedded inside.

[0008] In a preferred embodiment, the anchoring mechanism includes an anchor rod disposed within an anchoring hole, an anchor plate slidably disposed at the upper end of the anchor rod above the anchoring hole, an anchoring fastening nut disposed at the upper end of the anchor rod above the anchor plate, a bent piece fixedly disposed at the lower end of the anchor rod, and an elastic retaining ring uniformly fixedly disposed on the inner side of the bent piece, the elastic retaining ring being sleeved on the outer side of the lower end of the anchor rod.

[0009] In a preferred embodiment, the lower part of the bent piece is pointed and the two sides are symmetrically arranged. From bottom to top, the bent piece consists of a pointed part, an elastic extrusion part, and an opening and closing part. The gap between the opening and closing parts is larger than the gap between the elastic extrusion parts. The outer side of the elastic fixing ring is welded to the inner side of the elastic extrusion part.

[0010] In a preferred embodiment, the UHPC hyperbolic panel has pre-embedded prestressed tendons, which are prestressed steel strands.

[0011] In a preferred embodiment, a water-absorbing layer is fixedly provided on the lower part of the UHPC hyperboloid panel. The water-absorbing layer is made of a high-polymer waterproof material, and a buffer layer is fixedly provided below the water-absorbing layer. The buffer layer is an elastic pad.

[0012] In a preferred embodiment, the lower end of the anchor rod is fixedly connected to the inner side of the bent piece by welding.

[0013] In a preferred embodiment, the external dimensions of the end positioning block are the same as the internal dimensions of the end positioning groove. During installation, the end positioning block of the UHPC hyperbolic panel engages with the end positioning groove of the adjacent UHPC hyperbolic panel.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] Excellent drainage and ventilation performance: The design of the drainage system and ventilation holes effectively prevents water accumulation and humidity buildup, keeping the site dry and well-ventilated.

[0027] like Figure 1 and Figure 2 As shown, a hyperbolic component for the curved surface of a UHPC speed skating stadium includes a UHPC hyperbolic panel 1. Both sides of the UHPC hyperbolic panel 1 are curved surfaces, and the curvature directions of the two curved surfaces of the UHPC hyperbolic panel 1 are the same. A lower support beam 2 is fixedly installed at the lower part of the UHPC hyperbolic panel 1. An end positioning block 3 is fixedly installed at one end of the UHPC hyperbolic panel 1, and an end positioning groove 4 is provided at the other end of the UHPC hyperbolic panel 1. The lower support beam 2 is inverted T-shaped, and anchoring holes 5 are symmetrically arranged on both sides of the lower support beam 2. An anchoring mechanism 6 is fixedly installed inside the anchoring holes 5. The UHPC hyperbolic panel 1 and the lower support beam 2 are an integral structure, and a reinforcing mesh 7 is pre-embedded inside. Prestressed tendons 8, which are prestressed steel strands, are pre-embedded inside the UHPC hyperbolic panel 1. A water-absorbing layer 9, made of a high-polymer waterproof material, is fixedly installed at the bottom of the UHPC hyperbolic panel 1. A buffer layer 10, which is an elastic pad, is fixedly installed below the water-absorbing layer 9. The external dimensions of the end positioning block 3 are the same as the internal dimensions of the end positioning groove 4. During installation, the end positioning block 3 of the UHPC hyperbolic panel 1 engages with the end positioning groove 4 of the adjacent UHPC hyperbolic panel 1.

[0028] like Figure 2 and Figure 3 As shown, the anchoring mechanism 6 includes an anchor rod 61 disposed within the anchoring hole 5. An anchor plate 62 is slidably disposed at the upper end of the anchor rod 61 above the anchoring hole 5. An anchoring nut 63 is disposed at the upper end of the anchor rod 61 above the anchor plate 62. A bent piece 64 is fixedly disposed at the lower end of the anchor rod 61. Elastic retaining rings 65 are evenly fixedly disposed on the inner side of the bent piece 64, and the elastic retaining rings 65 are sleeved on the outer side of the lower end of the anchor rod 61. The lower end of the anchor rod 61 is fixedly connected to the inner side of the bent piece 64 by welding.

[0029] like Figure 3 and Figure 4 The lower part of the bent piece 64 is pointed and the two sides are symmetrically arranged. From bottom to top, the bent piece 64 consists of a pointed part 641, an elastic extrusion part 642 and an opening and closing part 643. The gap in the middle of the opening and closing part 643 is larger than the gap between the elastic extrusion parts 642. The outer side of the elastic fixing ring 65 is welded to the inner side of the elastic extrusion part 642.

[0030] This invention utilizes ultra-high performance concrete (UHPC). The UHPC hyperbolic panel 1 features a hyperbolic surface design to meet the curvature requirements of speed skating stadium curves, improving athlete stability and safety during skating. The reinforcing mesh 7, made of high-strength steel bars or steel fibers, is arranged inside the UHPC hyperbolic panel to form a mesh structure, enhancing the overall strength and crack resistance of the panel. Prestressed tendons 8 are tensioned and fixed before UHPC pouring, applying prestress to improve the component's load-bearing capacity and deformation resistance. A water-absorbing layer 9 is laid beneath the hyperbolic panel to prevent moisture penetration and protect the internal structure from corrosion. A buffer layer 10 reduces impact and noise during skating, improving comfort. Anchoring mechanism 6 firmly fixes the lower support beam 2 to the foundation, ensuring the stability of the entire component. The anchoring mechanism 6 is securely anchored, preventing loosening and ensuring high safety.
