[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] like Figures 1 to 5 As shown, a novel connecting device is used for quickly connecting structural steel to a connecting object. The device includes a first double-ended connecting stud 1, a second double-ended connecting stud 2, and a through-hole connecting nut 3. The connecting nut 3 is used to install onto the connecting object. One end of the first double-ended connecting stud 1 passes through the hollow cavity of the connecting nut 3 and is threadedly connected to it. One end of the second double-ended connecting stud 2 passes through the hollow cavity of the connecting nut 3 away from the first double-ended connecting stud 1 and is threadedly connected to it. The ends of the first double-ended connecting stud 1 and the second double-ended connecting stud 2 that pass through the hollow cavity of the connecting nut 3 and are close to each other are used for limiting connection.

[0030] In this embodiment, the connecting nut 3 of the connecting device is installed and fixed in the designed position. Then, a first double-ended connecting stud 1 passes through the connecting hole of the steel profile and is threaded onto one end of the connecting nut 3. The other end of the connecting nut 3 is used to connect a second double-ended connecting stud 2. The second double-ended connecting stud 2 can connect and limit other connecting objects, or it can serve as a limiting member to fix the other end of the connecting nut 3. One end of the second double-ended connecting stud 2 is inserted into the other end of the connecting nut 3, and the other end of the connecting nut 3 is fixed and limited by the connecting fixing object through which the second double-ended connecting stud 2 passes or by the second double-ended connecting stud 2 itself. In this way, the steel profile is connected and fixed in the designed position of the connecting object through this connecting device, realizing rapid connection and installation and saving time.

[0031] Example 2

[0032] Based on Embodiment 1, the first double-ended connecting stud 1 is connected to one end of the connecting nut 3 with a limiting connecting hole 11; the second double-ended connecting stud 2 is connected to one end of the connecting nut 3 with an expansion bolt head 21; the expansion bolt head 21 is used to pass through the limiting connecting hole 11 and is limited to the limiting connecting hole 11; by using the expansion bolt head 21 to pass through the limiting connecting hole 11 and be limited to the limiting connecting hole 11 (expansion bolt structural principle), the steel section and the connecting object are securely connected and fixed by the connecting device.

[0033] Meanwhile, the first double-end connecting stud 1 is connected with a first connecting pad 12 away from the connecting nut 3, and the first connecting pad 12 is connected with a first bolt connecting head 13 away from the first double-end connecting stud 1. Also, the second double-end connecting stud 2 is connected with a second connecting pad 22 away from the connecting nut 3, and the second connecting pad 22 is connected with a second bolt connecting head 23 away from the second double-end connecting stud 2; by controlling and driving the first bolt connecting head 13 and the second bolt connecting head 23 with a tool, the first double-end connecting stud 1 and the second double-end connecting stud 2 are driven to move relatively and close to each other under the limiting and guiding action of the connecting nut; when the expansion bolt head 21 is arranged in the limiting connecting hole 11 and abuts against the bottom end of the limiting connecting hole 11, the expansion bolt head 21 is “unfolded” and abuts against and clamped in the limiting connecting hole 11, the first double-end connecting stud 1 and the second double-end connecting stud 2 are limited and connected by the connecting nut 3, and then the profile steel is stably connected on the connected object by the connecting device. Also, the first double-end connecting stud 1, the second double-end connecting stud 2 and the connecting nut 3 arranged in series are respectively sprayed with a layer of protective paint for protection; in this way, the service life of the whole device can be increased, the frequency of maintenance and replacement in the later period can be reduced, and the cost can be saved.
