DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides an assembling connector for an aviation deck of a helicopter landing pad, comprising an assembling connector body, wherein the assembling connector body is adapted to a splicing cavity formed when two aviation decks are spliced ​​together, and when the assembling connector is fixed in the splicing cavity, the top of the assembling connector contacts the top of the assembling cavity, the bottom of the assembling connector is at the same height as the bottom of the aviation deck, a part of the assembling connector is in an exposed state, and the part of the assembling connector exposed outside the splicing cavity can contact the top of the main beam. At this time, the staff can use bolts to fix the assembling connector and the main beam together, and then the splicing of the main beam and the aviation deck can be achieved through the assembling connector, so as to avoid the situation where there is no construction working surface and M12 stainless steel bolts cannot be installed to fix the aviation deck and the steel beam, thereby facilitating the construction of the helicopter landing pad.

[0023] The outer surface of the assembly connector body is wrapped with a sealing strip, which can be made of rubber. Through the provision of the sealing strip, the installation error of the assembly connector caused by construction error can be reduced, thereby ensuring the installation quality of the helicopter pad. The resilience of the sealing strip can reduce the pressure at the joint of the aviation deck, so that the assembly connector body can achieve maximum pressure resistance while optimizing the overall performance of the helicopter pad aviation deck.

[0024] The above-mentioned assembly connector body includes an upper support part and a lower support part, and the thickness value of the material of the upper support part and the lower support part is the same. In some embodiments of the present application, the material of the assembly connector body is aluminum alloy. The upper support part and the lower support part share a middle beam 2, the upper support part also includes an upper beam 1, an upper left support member 4 and an upper right support member 5, the lower support part also includes a lower left support member 6, a lower right support member 7, a transition beam 8 and a lower beam 3, the upper left support member 4 and the lower left support member 6 are both located on the same side of the middle beam 2, the upper left support member 4 and the lower left support member 6 are both on the same straight line, the upper right support member 5 and the lower right support member 7 are both located on the other side of the middle beam 2, the transition beam 8 and the lower left support member 6 or the lower right support member 7 are in a smooth transition state, and the transition surface between the transition beam 8 and the lower left support member 6 or the lower right support member 7 is an outwardly convex arc surface, and the upper beam 1, the middle beam 2, the lower beam 3 and the transition beam 8 are all in a horizontal state.

[0025] In some embodiments of the present application, the assembly connector body is made of 3 mm thick aluminum alloy through one-piece molding technology, the length of the assembly connector body is 260 mm, the length of the upper beam 1 is 12 mm, the length of the lower beam 3 is 48.1 mm, the height of the lower beam 3 is 9 mm, the length of the upper left support 4 is 44 mm, the length of the upper right support 5 is 58 mm, the length of the lower left support 6 is 39 mm, the length of the lower right support 7 is 36 mm, and the length of the transition beam 8 is 24 mm.

[0026] The assembly connector body is fixedly connected to the aviation deck through a connection structure. In one embodiment 1 of the present application, the connection structure is a core expansion nail 10, as shown in the attached specification. Figure 3 As shown, two aviation decks 9 assembled together can be fixed together using core expansion nails 10.

[0027] In an embodiment 2 of the present application, the connection structure includes a support plate 12, and a connecting sleeve 11 is fixed on both sides of one side of the support plate 12. A through rod 13 is connected to the inner cavity of the connecting sleeve 11 through a spring 14. Both ends of the support plate 12 are connected to a moving rod 16 through a spring 2. The moving rod 16 is fixedly connected to one end of the connecting sleeve 11 close to a blocking block 15. The blocking block 15 contacts the end of the connecting sleeve 11. The through rod 13 can be limited by the blocking block 15, so that when the connection structure is not in use, the through rod 13 is located in the inner cavity of the connecting sleeve 11, and the spring 14 is in a compressed state. When the connection structure is in use, the staff After both sides of the two aviation decks and one end of the assembly connector are provided with through grooves adapted to the through rod 13, the aviation deck is fixedly connected to the end of the support plate 12, and the staff inserts the assembly connector into the splicing cavity formed by the two aviation decks. The splicing connector can squeeze the blocking block 15 during the movement, so that the blocking block 15 gradually moves away from the through rod 13. When the blocking block 15 is separated from the through rod 13, the through groove on the aviation deck overlaps with the through groove on the assembly connector, and the through rod 13 moves outward under the action of the spring 14 rebound force. The through rod 13 can penetrate the two overlapping through grooves at the same time, so as to realize the rapid fixation of the aviation deck and the assembly connector. Through the setting of the connection structure, the aviation deck and the assembly connector can be quickly spliced, and when the connection structure is used, it is convenient for the staff to connect the aviation deck with the connection structure.

[0028] To sum up: during the construction of the helicopter pad, if there is no construction working surface between the aviation deck and the steel beam main beam, the workers can use the connection structure to connect one end of the assembly connector and the two aviation decks into a whole, and then use the M12 stainless steel bolts to fix the other end of the assembly connector to the main beam. The connection between the aviation deck and the main beam is indirectly achieved through the assembly connector, which solves the problem of no working surface for installing M12 stainless steel bolts in the existing construction. In addition, the assembly connector can achieve maximum compressive resistance while optimizing the overall performance of the helicopter pad aviation deck.
