[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a quick fixing device for roof purlins, including a steel beam frame 1 and an adjustment mechanism 3. A connecting shell 2 is provided on the top of the steel beam frame 1, and a purlin support plate 4 and two sets of purlins 5 are provided above the steel beam frame 1. The adjustment mechanism 3 is provided on the connecting shell 2 and is used to adjust the height of the purlin support plate 4.

[0017] The adjusting mechanism 3 includes a threaded rod 301, a first connecting block 302, a second connecting block 303, and a connecting plate 304. The threaded rod 301 is threadedly connected to one side of the connecting housing 2. One end of the threaded rod 301 extends into the interior of the connecting housing 2 and is rotatably mounted with the first connecting block 302. The second connecting block 303 is slidably mounted inside the connecting housing 2 and is in contact with the first connecting block 302. The connecting plate 304 is fixedly mounted on the top of the second connecting block 303. The adjusting mechanism 3 can adjust the height of the purlin support plate 4, thereby enabling the purlin support plate 4 to be used with purlins 5 of different sizes. Compared with fixing by fastening plate components of fixed size, it can improve the applicability of the quick fixing device for ceiling purlins, thereby reducing the number of fastening plate specifications that need to be prepared during construction and improving the working efficiency of the fixing device.

[0018] One end of the connecting plate 304 extends to the top of the connecting housing 2, and the purlin support plate 4 is fixedly installed at the bottom of the connecting plate 304.

[0019] Two sets of through holes are provided on one side of the purlin support plate 4, and corresponding through holes are provided on both sets of purlins 5. Two sets of bolts 6 are slidably installed on one side of the purlin support plate 4. One end of each set of bolts 6 extends through the through holes to one side of the purlin 5, and the other end of each set of bolts 6 extends through the through holes to the other side of the purlin support plate 4. Two sets of nuts 7 are threadedly connected to the outer wall of each set of bolts 6.

[0020] A handle 8 is fixedly installed at the other end of the threaded rod 301. A groove is provided on the bottom inner side of the connecting housing 2. A slider 9 is slidably installed in the groove. The top of the slider 9 is fixedly connected to the connecting block 302.

[0021] Four sets of bolts 210 are fixedly installed at the bottom of the connecting shell 2. Four sets of round holes are opened at the top of the steel beam frame 1. One end of each of the four sets of bolts 210 extends through the round holes to the inside of the steel beam frame 1. Nuts 211 are threaded onto the outer wall of each of the four sets of bolts 210. Bolts 210 and nuts 211 can be separated, thereby allowing the connecting shell 2 to be disassembled from the steel beam frame 1. After construction, the connecting shell 2 can be recycled and reused, making it suitable for the construction of temporary buildings and exhibition venues, and reducing installation costs.

[0022] Working principle: When work is required, the holes on the two sets of purlins 5 are aligned with the holes on the purlin support plate 4. The two sets of purlins 5 can be fixed by bolt 6 and nut 7. When it is necessary to fix purlins 5 of different sizes, the threaded rod 301 is rotated by the handle 8, and the slider 9 slides in the groove, so that the connecting block 302 moves laterally. Through the contact between the connecting block 302 and the connecting block 303, the connecting block 303 can drive the connecting plate 304 to move upward, thereby adjusting the height of the purlin support plate 4. The holes on the purlin support plate 4 are aligned with the holes on the two sets of purlins 5, and they can be fixed. After the project is completed, the purlins 5 are disassembled. By rotating the nut 11, the nut 11 can be separated from the bolt 10. At this time, the connecting housing 2 can be separated from the steel beam frame 1, and the connecting housing 2 can be recycled.
