The aluminum alloy formwork is mainly made of aluminum alloy profiles and is a formwork suitable for concrete projects after being processed by machinery and welding and other processes.

[0003] During the use of the aluminum formwork, it is necessary to splice and lock multiple aluminum formworks through the cooperation of screws and nuts. When installing the screws and nuts, two gaskets (nut end and screw end) also need to be sleeved on the screws. Since a lot of screws need to be installed when connecting and locking the aluminum formwork, plus the time consumed by sleeving the gaskets, this will make the splicing and locking work of the aluminum formwork very slow. For this reason, a quick locking mechanism for aluminum formwork in construction engineering is proposed. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] The present invention provides a technical solution: As Figures 1 to 5 shown, in this embodiment, a quick locking mechanism for an aluminum formwork in a construction project includes an aluminum formwork body 1 and a screw rod 5. A plurality of connection holes 2 are opened on the side wall of the aluminum formwork body 1. The screw rod 5 is located inside the connection hole 2. One end of the screw rod 5 is fixedly connected with a nut 3. A cross slot 6 is opened at the end of the nut 3 away from the screw rod 5. The other end of the screw rod 5 is sleeved with a nut 8 and is connected to the nut 8 through thread fit. A receiving section 13 is opened on the outer wall of the screw rod 5 near the nut 3. A first gasket 7 is movably sleeved on the outer surface of the receiving section 13. A second gasket 9 is arranged at the end of the nut 8 near the nut 3. Three guide rods 10 are fixedly connected to the side wall of the second gasket 9 near the nut 8. The three guide rods 10 are arranged in a circular array. The end of the guide rod 10 slides through a through slot 12 opened in the nut 8 and is fixedly connected with a limiting plate 11.

[0022] Among them, the diameter of the limiting plate 11 is greater than the diameter of the through slot 12, and the limiting plate 11 is made of soft rubber material.

[0023] With such a setting, when the guide rod 10 on the second gasket 9 penetrates through the through slot 12 on the nut 8, the second gasket 9 will not break away from the nut 8, and the use of a soft material for the limiting plate 11 can ensure that the limiting plate 11 can pass through the through slot 12 when affected by an external force.

[0024] Among them, an inner sleeve 17 is fixedly connected to the inner ring side wall of the first gasket 7. The inner sleeve 17 is made of soft rubber material. The diameter of the first gasket 7 is greater than the diameter of the screw rod 5. The diameter of the inner sleeve 17 is smaller than the diameter of the screw rod 5. The inner diameter of the first gasket 7 is greater than the diameter of the receiving section 13.

[0025] With such a setting, when the first gasket 7 is sleeved on the outer surface of the receiving section 13, the inner sleeve 17 can ensure that the first gasket 7 does not break away from the receiving section 13.

[0026] Among them, a fixed plate 14 is sleeved on the outer wall of the nut 8 and is fixedly connected to the fixed plate 14. A protective sleeve 4 is arranged at the end of the fixed plate 14 away from the nut 3. A card slot 15 for accommodating the protective sleeve 4 is opened on the fixed plate 14.

[0027] The set protective sleeve 4 can protect the part of the screw rod 5 that extends out, preventing the extended end of the screw rod 5 from being exposed to the air and rusting, which would affect the disassembly of the screw rod 5.

[0028] Wherein, one end of the protective sleeve 4 close to the fixed plate 14 is fixedly connected with a clamping plate 16. The thickness of the clamping plate 16 is greater than that of the clamping groove 15, and the clamping plate 16 is made of soft rubber material.

[0029] The set clamping plate 16 can clamp the protective sleeve 4 in the clamping groove 15 of the fixed plate 14.

[0030] The utility model provides a quick locking mechanism for aluminum formwork in construction engineering, and the specific working principle is as follows:

[0031] The locking mechanism is provided with a receiving section 13 on the screw rod 5 and an inner sleeve 17 on the inner ring side wall of the first gasket 7, so that the first gasket 7 can be installed on the screw rod 5 and ensure that the first gasket 7 will not fall off. By providing a guide rod 10 and a limiting plate 11 on the second gasket 9 and a through groove 12 on the nut 8, the second gasket 9 can be installed on the nut 8 and ensure that the second gasket 9 will not fall off. Before splicing and locking the aluminum formwork, the first gaskets 7 and the second gaskets 9 can be respectively installed on all the screw rods 5 and the nuts 8 in a centralized manner. In this way, when installing the screw rods 5 and the nuts 8, there is no need to slowly sleeved the gaskets, which can effectively improve the splicing and locking efficiency of the aluminum formwork. At the same time, the set protective sleeve 4 can protect the part of the screw rod 5 that extends out, preventing the extended end of the screw rod 5 from being exposed to the air and rusting, which would affect the disassembly of the screw rod 5.

[0032] Although the embodiments of the utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
