[0033] Example

[0034] like Figures 1-7 As shown, this utility model proposes a prefabricated aircraft parking apron, including a bracket 1. The bracket 1 consists of a fixed support 11 and a connecting support 12. The fixed support 11 is fixedly installed on the concrete ground by bolts. The connecting support 12 is fixedly installed on the top of the fixed support 11 to support the modular platform 5, preventing water accumulation on the ground from causing corrosion of the modular platform 5 and improving its durability. A support plate 2 is fixedly installed on the top of the connecting support 12. Two support seats 3 are fixedly installed on the upper surface of the support plate 2. Two locking screws 4 are movably installed on the support seats 3. The locking screws 4 are used to lock and fix the modular platform 5. The modular platform 5 is composed of two first platform plates 51 and several second platform plates 52 spliced ​​together. The first platform plates 51 are engaged. Installed on top of support base 3, several second platform plates 52 are set between two first platform plates 51. After multiple platform plates are assembled into one, they form a complete landing pad platform, which can provide a flat support surface for helicopter take-off and landing. The bottom of the first platform plate 51 and the second platform plate 52 are fixedly installed with longitudinal limiting posts 53. The lower surface of the longitudinal limiting posts 53 is fixedly installed with a longitudinal connecting plate 54. The locking screw 4 passes through the longitudinal connecting plate 54 and is movably connected to it. The longitudinal connecting plate 54 is locked and limited by the locking screw 4, ensuring that the modular platform 5 can be stably erected above the support plate 2. The modular structure and the fact that it can be locked and fixed by two locking screws 4 improve the ease of assembly of the modular platform 5.

[0035] Further such as Figure 3As shown, the upper surface of the support plate 2 is fixedly provided with a plurality of card seats 21, and rubber blocks 22 are embedded in the grooves at the top ends of the card seats 21. The bottom ends of the longitudinal connecting plates 54 are inserted into the grooves at the top ends of the matching rubber blocks 22 and tightly clamped thereon. The bottom ends of the longitudinal connecting plates 54 are cushioned and damped by the rubber blocks 22, thereby improving the anti-vibration effect of the combined table top 5. The support seat 3 is provided with a horizontal through hole 34, and a horizontal rubber sleeve 35 is arranged at the horizontal through hole 34. After the locking screw 4 passes through the horizontal rubber sleeve 35, the horizontal rubber sleeve 35 is tightly clamped in the gap between the outer wall of the locking screw 4 and the inner wall of the horizontal through hole 34. When the locking screw 4 is subjected to the pressure applied by the longitudinal connecting plate 54, the horizontal rubber sleeve 35 can improve the anti-vibration effect of the contact part between the locking screw 4 and the longitudinal connecting plate 54.

[0036] Secondly, as shown in the figure, Figure 2 The bottom ends of the longitudinal limiting columns 53 pass through the matching longitudinal through holes 33 and are movably connected thereto, so as to limit the horizontal movement of the longitudinal limiting columns 53 and improve the stability of the combined table top 5 after installation. The longitudinal limiting columns 53 are movably sleeved with longitudinal rubber sleeves 56, which are tightly clamped between the matching first table plates 51, second table plates 52 and support plates 2. When the vibration generated during the take-off and landing of the helicopter is applied to the longitudinal limiting columns 53, the longitudinal rubber sleeves 56 can cushion and damp the longitudinal limiting columns 53, thereby improving the anti-vibration effect of the combined table top 5.

[0037] Secondly, the top end of the support seat 3 is provided with a circular insertion groove 31, and the lower surface of the first table plate 51 is fixedly provided with a limiting insertion rod 55. The limiting insertion rod 55 is inserted into the matching circular insertion groove 31 and is clamped and connected therewith, so as to facilitate the positioning and pre-assembly of the first table plate 51. The positioning of the limiting insertion rod 55 by the circular insertion groove 31 can prevent the horizontal movement of the first table plate 51 and ensure that the two first table plates 51 can limit the horizontal movement of the plurality of second table plates 52, thereby improving the stability of the combined table top 5 in the horizontal direction.

[0038] Further, as shown in the figure, Figure 4 , Figure 6As shown, the connecting bracket 12 comprises a first circular plate 121 and a plurality of second circular plates 122. Two adjacent second circular plates 122 are jointly fixedly installed with a semicircular reinforcing plate 123, which ensures that the plurality of second circular plates 122 distributed in a ring shape can be connected as a whole. The semicircular reinforcing plate 123 and the first circular plate 121 are jointly fixedly installed with a fan-shaped reinforcing plate 124, which ensures that the semicircular reinforcing plate 123 can be firmly connected with the first circular plate 121, and then the first circular plate 121 and the second circular plate 122 are connected as a whole, thereby strengthening the structural strength of the connecting bracket 12. The first circular plate 121, the second circular plate 122, the semicircular reinforcing plate 123, and the fan-shaped reinforcing plate 124 can form a support surface with multiple support points, which not only can stably support the support plate 2, but also can reduce the weight of the support surface and facilitate transportation during installation.

[0039] As shown in Figure 7 The top of the second circular plate 122 is provided with a hexagonal butt joint groove 125. The lower surface of the support plate 2 is fixedly installed with a plurality of hexagonal butt joint blocks 23. When the support plate 2 is fixed on the top of the connecting bracket 12, the hexagonal butt joint blocks 23 are embedded in the hexagonal butt joint groove 125, which can support the support plate 2 in the horizontal direction and improve the firmness of the connection between the support plate 2 and the connecting bracket 12. The hexagonal butt joint groove 125 is provided with a hexagonal rubber ring 126, which is tightly clamped between the inner side wall of the hexagonal butt joint groove 125 and the outer side wall of the hexagonal butt joint block 23, which can have a horizontal damping effect on the hexagonal butt joint block 23.

[0040] It is worth mentioning that, Figure 5 The fixed bracket 11 is composed of a first circular seat 111 and a plurality of second circular seats 112. The top of the first circular seat 111 is fixedly installed with a load-bearing column 115, and the top end of the load-bearing column 115 is fixedly connected with the first circular plate 121. Through the load-bearing column 115, a stable support structure can be provided at the bottom of the support plate 2 and near the central part. The top end of the second circular seat 112 is fixedly installed with a support rod 113, and the top end of the support rod 113 is fixedly connected with the second circular plate 122. Through the second circular plate 122, the contact area of the support rod 113 and the support plate 2 at the connection position can be increased. In combination with the stable support of the load-bearing column 115 and the first circular plate 121 to the support plate 2, the load-bearing capacity and stability of the support plate 2 are effectively enhanced. The support rod 113 and the load-bearing column 115 are jointly fixedly installed with a reinforcing rod 114, which ensures that the support rod 113 can be firmly connected with the load-bearing column 115 as a whole, thereby ensuring the structural strength of the fixed bracket 11.

[0041] In this embodiment, first, in the installation stage of the parking apron, the bracket 1 is placed on the ground in the installation area, the first circular seat 111 and the second circular seat 112 are fixed on the ground poured with concrete through expansion bolts, and the firmness of the fixed support 11 after installation is ensured; the support plate 2 is placed on the top of the connecting support 12, the bolt is punched from below the first circular plate 121 and is threadedly connected with the internal threaded groove at the bottom end of the support plate 2, then the support plate 2 is fixed and assembled on the top of the connecting support 12, in order to improve the firmness of the connection, the edges of the contact surface between the lower surface of the support plate 2 and the upper surface of the connecting support 12 can be spot-welded, and the firmness of the connection between the support plate 2 and the connecting support 12 is strengthened; after the installation of the support plate 2 is completed, the combined deck 5 can be assembled, the first deck plate 51 is clamped and installed on the top of the support seat 3, then the second deck plate 52 is additionally installed in the area between the two first deck plates 51, and after the plurality of second deck plates 52 are tightly spliced between the two first deck plates 51, the first deck plate 51 and the second deck plate 52 are locked and fixed; at this time, the locking screw 4 is installed on the two support seats 3, and after the locking screw 4 passes through the longitudinal connecting plate 54, the longitudinal limiting column 53 is locked and fixed, so that the first deck plate 51 and the second deck plate 52 can be firmly installed above the support plate 2, and the nut is installed at the threaded end of the locking screw 4, and after the nut tightly contacts the corresponding support seat 3, the locking screw 4 is fixed, so that the firmness of the combined deck 5 after installation is improved; the deck structure for the take-off and landing of the aircraft is formed by splicing a plurality of deck plates, and the locking and fixing of the deck structure can be completed by two locking screws 4, so that the convenience of the installation of the combined deck 5 is effectively improved.

[0042] In the use stage of the parking apron, in the process of the take-off and landing of the helicopter, the combined deck 5 not only needs to bear the weight of the helicopter, but also needs to cope with the pressure exerted by the vibration generated during the take-off and landing of the helicopter; the longitudinal rubber sleeve 56 sleeved on the longitudinal limiting column 53 and the rubber block 22 installed at the bottom of the longitudinal connecting plate 54 can play a damping and buffering role on the vibration received by the first deck plate 51 and the second deck plate 52; the transverse rubber sleeve 35 can be used for damping treatment of the locking screw 4, so as to improve the durability of the locking screw 4, reduce the probability of deformation, and ensure the stability of the locking and fixing of the combined deck 5; a large number of damping structures are arranged at the connecting and fixing parts of the combined deck 5, so as to strengthen the anti-seismic ability of the parking apron, reduce the probability of loosening of the fixed parts of the combined deck 5, and effectively improve the firmness of the assembled parking apron structure.
