Description

Technical Field

[0001] This utility model belongs to the field of low-altitude airport construction technology, and in particular relates to a maintenance-free apron deck for use in the construction of low-altitude airports. Background Technology

[0002] Currently, aircraft decks are mostly made of aluminum alloy, with a corrosion-resistant lifespan of 50 years. They require no maintenance within their designed service life and do not need repeated application of anti-corrosion coatings, providing excellent outdoor corrosion resistance. However, the design service life of roof waterproofing is only 15 years. After reaching this lifespan, roof leaks increase. The addition of elevated takeoff and landing pads further complicates roof waterproofing repairs. To prevent leaks from deck gaps and ensure roof waterproofing effectiveness, adhesive is often used to fill the gaps in the deck joints as a substitute for roof waterproofing repairs. However, the quality of the adhesive varies greatly, and the application quality is generally poor, making it difficult to achieve a waterproofing effect. This often results in situations where it rains heavily above and lightly below in the elevated takeoff and landing pads, and even repeated repairs rarely provide satisfactory waterproofing.

[0003] In harsh and cold regions during winter, takeoff and landing pads often freeze over due to snowfall. Although the deck surface has raised stripes to increase the coefficient of friction, these are ineffective once covered by ice, posing a significant risk to aircraft landings and potentially causing loss of life and property. Existing elevated takeoff and landing pads either lack de-icing facilities, making manual de-icing dangerous and prone to accidents involving falls; or they are equipped with electric heat tracing systems, but the replacement and maintenance of these systems have not been considered, making long-term operation difficult and lacking a sustainable solution. Therefore, creating a solution to address the replacement and maintenance issues of electric heat tracing systems and ensure their long-term operation to protect aircraft takeoff and landing safety has become an urgent need.

[0004] Currently, most aircraft decks are made of aluminum alloy, which offers good corrosion resistance and requires no maintenance within its design lifespan. However, the roof waterproofing has a relatively short design lifespan and is difficult to maintain. Commonly used filler adhesives have poor waterproofing performance, and elevated landing pads are prone to leakage. In extremely cold regions, the deck is prone to icing, and existing de-icing facilities are either lacking or difficult to maintain. Therefore, developing a waterproof, slip-resistant, easy-to-maintain, and cold-weather-adaptable maintenance-free apron deck is an urgent need.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0030] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1: Please see Figure 1-4 As shown, this utility model is a maintenance-free apron deck, including a row of decks 1 connected side by side, a row of supports 2 spaced apart, and water tanks 3 installed at both ends of the decks 1. The supports 2 are placed below the decks 1, and the decks 1 and supports 2 are connected by a first fastener to ensure structural stability and load-bearing capacity. The water tanks 3 are provided with connecting plates 304 and water-retaining grooves 305 that overlap with the ends of the decks 1, and the connecting plates 304 and water-retaining grooves 305 are connected to the decks 1 by a second fastener to achieve reliable water guidance. The second fastener is preferably a self-tapping screw, and the self-tapping screw is used in conjunction with a rubber ring.

[0032] The deck 1 comprises a horizontally parallel surface plate 111 and a bottom plate 113. The surface plate 111 has several rows of circular holes 101, which help reduce the overall weight of the deck and enhance drainage performance. The surface plate 111 also has several rows of anti-slip stripes 102 to increase friction during aircraft takeoff and landing, ensuring safety. The anti-slip stripes 102 have several water channels 103 along their length, which effectively drain water from the surface of the deck 1, preventing slippage caused by water accumulation. Multiple parallel cavities 105 are provided between the surface plate 111 and the bottom plate 113 of the deck 1. These cavities 105 are mainly used for drainage, secondly to reduce the weight of the deck, and also have some heat insulation and sound insulation effects. The bottom plate 113 has an upward-protruding groove 112 in the center that engages with a first fastener, facilitating the installation and adjustment of the deck and the support 2. In this embodiment, the support 2 adopts an I-beam profile. The first fastener uses a T-bolt that mates with the slide groove 112, combined with a nut and a washer. The washer is placed on the support 2 and the nut is used to pre-tighten it to connect the support 2 to the deck 1. The connecting plate 304 is fastened to the surface plate 111, and the water-blocking groove 305 abuts against the lower surface of the bottom panel 113, together forming a complete waterproof system.

[0033] A protrusion 106 is provided on one side of the surface plate 111. A groove 107 is provided on the opposite side of the surface plate 111 to connect and mate with the protrusion 106, and a first drip 109 is provided at the lower end of the groove 107. A third drip 114 is provided below the protrusion 106, arranged parallel to the first drip 109. A water collection and guiding device is provided between two adjacent decks 1 after they are connected. When the two decks 1 are connected side-by-side, both the first drip 109 and the third drip 114 are positioned directly above the water collection and guiding device, forming an effective water guiding system to prevent water from seeping in through the deck gaps. In this embodiment, the water collection and guiding device is a water collection trough 108 fixed below the protrusion 106; a reserved space 110 is provided between the upper outer end of the water collection trough 108 and the protrusion 106. The reserved space 110 between the upper outer end of the water collection trough 108 and the protrusion 106 facilitates the smooth drainage of water.

[0034] In addition, the lower half of the surface panel 111 is provided with several reserved channels 104 along its length for installing electric heat tracing cables. These reserved channels 104 facilitate the installation of the electric heat tracing system and ensure that the deck will not affect the safety of aircraft take-off and landing due to icing in frigid regions. The reserved channels 104 have a circular or triangular cross-section to accommodate electric heat tracing cables of different specifications.

[0035] The water tank 3 includes a water guide channel 301 with its opening facing upwards and arranged side by side, a cable channel 302, and a splash water droplet collecting and guiding channel 303 located below and opening towards the deck 1.

The splash water droplet collecting and guiding channel 303 has an opening in the upper part of the adjacent deck 1, and this opening is a continuous channel 308. A second drip 306 is provided at the top of the continuous channel 308, which facilitates the flow of water from the water collection tank 108 along the outer wall of the water tank 3 from the second drip 306 to the splash water droplet collecting and guiding channel 303. A connecting plate 304 is fixedly installed at the upper end of the side of the water guide channel 301 adjacent to the deck 1. A water-blocking groove 305 is fixedly installed at the bottom of the continuous channel 308, and the water-blocking groove 305 extends away from the splash water droplet collecting and guiding channel 303. The cavity 105 is connected to the splash water droplet collection and diversion channel 303, which facilitates the drainage of water accumulated inside the deck 1.

[0036] The bottom of the water guide channel 301 is provided with several holes 307 that communicate with the splash water droplet collecting and guiding channel 303, ensuring that the water in the water guide channel 301 can be smoothly discharged into the splash water droplet collecting and guiding channel 303. The side wall of the water guide channel 301 adjacent to the deck 1 is provided with several slots 310 that cooperate with the reserved channel 104, which facilitates the introduction and installation of electric heating cables.

[0037] It also includes a cable cover plate 313 installed on the upper end of the cable trough 302 to protect the cable from external environmental influences. A diversion baffle 309 has a mating groove 311 fixed to its side wall on one side of the water guide trough 301, which engages with the cable cover plate 313. An overlapping support plate 312 is fixed to the top of the inner side wall of the cable trough 302 away from the water guide trough 301 to support the cable cover plate 313, facilitating its installation and removal. The overlapping support plate 312 and the cable cover plate 313 are connected by a third fastener, forming a closed cable protection space. The third fastener is preferably a removable screw.

[0038] One specific application of this embodiment is in the construction of low-altitude airports. Using the maintenance-free apron deck of this invention can effectively solve problems such as poor waterproofing and icing in traditional decks. Through a reasonable structural design and waterproof drainage system, the deck can be used normally under various severe weather conditions, providing strong support for the safe takeoff and landing of aircraft. At the same time, the reserved installation holes for electric heating cables facilitate the use of the deck in extremely cold regions, further enhancing its applicability and safety. Specific Implementation Example 2: Based on Specific Embodiment 1, the difference in this embodiment lies in the water collection and guiding device: like Figure 5 As shown, in this embodiment, the water collection and guiding device is a water guiding channel 4, and a pair of overlapping protrusions 115 for supporting the water guiding channel 4 are fixed on the opposite outer side of the deck 1. The water guiding channel 4 is a detachable component, and its structure is slightly different from that of the deck 1 in Embodiment 1.
