The end of the insertion plate 30103 away from the horizontal plate and the edge away from the vertical plate are guided by a guide structure. Both the first C-shaped plate 301 and the second C-shaped plate 302 are manufactured using a process of bending stamped sheet metal.

[0050] The first C-shaped plate 301 has a first mounting hole 30101 on its vertical plate, and the second C-shaped plate 302 has a second mounting hole 30201 on its vertical plate. The clamping bolt 303 passes through the second mounting hole 30201 and the first mounting hole 30101 in sequence and is threadedly connected to the clamping nut 304. The supporting keel 1 is located between the vertical plate of the first C-shaped plate 301 and the vertical plate of the second C-shaped plate 302, and between the lower horizontal plate of the second C-shaped plate 302 and the clamping bolt 303.

[0051] The upper horizontal plate of the second C-shaped plate 302 has a connecting hole 30203.

[0054] Work process:

[0055] When implementing this solution, the installation process of connector 3 is as follows: The lower end of expansion screw 5 is passed through the connecting hole 30203 of the second C-shaped plate 302, and then threaded onto the first positioning nut 502. Rotating the position of the first positioning nut 502 adjusts the height of the supporting keel 1. The supporting keel 1 is placed on the horizontal plate at the lower end of the second C-shaped plate 302. Then, the groove 30102 of the first C-shaped plate 301 is aligned with the expansion bolt and inserted (the groove 30102 serves as a guide to facilitate the alignment of the insert plate 30103 with the insertion hole 30202). The first C-shaped plate 301... Under the guidance of the chamfered structure of the insert plate 30103, the horizontal plates at both ends deform. When the insert plate 30103 aligns with the slot, the horizontal plates reset. The insert plate 30103 is inserted into the slot. Then, the clamping bolt 303 passes through the second mounting hole 30201 and the first mounting hole 30101 and is threadedly connected to the clamping nut 304. The clamping bolt 303 prevents the second C-shaped plate 302 and the first C-shaped plate 301 from separating, and the clamping bolt 303 also serves to limit the upper section of the bearing keel 1. Finally, the second positioning nut 501 is tightened to fix the position of the connecting piece 3.

[0056] The installation process of the hanger is as follows: Insert the T-shaped connecting part 401 at the lower end of the bending plate 4 into the inner side of the covering keel 2, and make the horizontal plate of the bending plate 4 fit with the upper end surface of the bearing keel 1, bending the bending part 402 into the inner side of the bearing keel 1.

[0057] The connector 3 is composed of a first C-shaped plate 301 and a second C-shaped plate 302, which improves the structural strength of the connector 3, prevents the load-bearing keel 1 from moving, and improves the installation efficiency through the setting of the insert plate 30103 and the insertion hole 30202.

[0067] The supporting keel 1 is located between the vertical plate of the first C-shaped plate 301 and the vertical plate of the second C-shaped plate 302, and between the lower horizontal plate of the second C-shaped plate 302 and the clamping bolt 303.

[0068] The upper horizontal plate of the second C-shaped plate 302 has a connecting hole 30203. The lower end of the expansion screw 5 passes through the connecting hole 30203 and is threadedly connected to the first positioning nut 502. The upper horizontal plate of the first C-shaped plate 301 has a groove 30102 corresponding to the connecting hole 30203. The expansion screw 5 is located inside the groove 30102. The second positioning nut 501 is threadedly connected to the expansion screw 5.

One ear plate 605 of the hanging plate 601 has positioning grooves 607 at both ends, and a positioning plate 608 that matches the positioning grooves 607 is fixed to the ear plate 605 of the other hanging plate 601. A limiting boss 609 that limits the other ear plate 605 is fixed to the end of the positioning plate 608 away from the ear plate 605. The supporting keel 1 is installed between the two hanging plates 601, and the lower end of the hanging plate 601 is connected to the covering keel 2. The facing keel 2 is a square tube with a strip hole 201 at the upper end along its length. The hanging plate 601 has a T-shaped plate 603 at its lower end, which is installed on the inner side of the facing keel 2. The hanging plate 601 is made by bending stamped sheet material, resulting in low production cost.

[0070] One of the mounting plates 601 has a first through hole 606 on its ear plate 605, and the other mounting plate 601 has a second through hole 611 on its ear plate 605.

[0071] The expansion screw 5 may be, but is not limited to, the existing extended expansion screw 5.

[0072] Work process:

[0073] When implementing this solution, the installation process of connector 3 is as follows: The lower end of expansion screw 5 is passed through the connecting hole 30203 of the second C-shaped plate 302, and then threaded onto the first positioning nut 502. Rotating the position of the first positioning nut 502 adjusts the height of the supporting keel 1. The supporting keel 1 is placed on the horizontal plate at the lower end of the second C-shaped plate 302. Then, the groove 30102 of the first C-shaped plate 301 is aligned with the expansion bolt and inserted (the groove 30102 serves as a guide to facilitate the alignment of the insert plate 30103 with the insertion hole 30202). The first C-shaped plate 301... Under the guidance of the chamfered structure of the insert plate 30103, the horizontal plates at both ends deform. When the insert plate 30103 aligns with the slot, the horizontal plates reset. The insert plate 30103 is inserted into the slot. Then, the clamping bolt 303 passes through the second mounting hole 30201 and the first mounting hole 30101 and is threadedly connected to the clamping nut 304. The clamping bolt 303 prevents the second C-shaped plate 302 and the first C-shaped plate 301 from separating, and the clamping bolt 303 also serves to limit the upper section of the bearing keel 1. Finally, the second positioning nut 501 is tightened to fix the position of the connecting piece 3.

[0074] The installation process of the hanger is as follows: Insert the T-shaped plates 603 at the lower end of the two hanger plates 601 into the covering keel 2. Then, align the positioning plate 608 on the ear plate 605 of one hanger plate 601 with the positioning groove 607 of the ear plate 605 of the other hanger plate 601. Move the positioning plate 608 under the guidance of the limiting boss 609 guide structure. The ear plate 605 and the mounting plate 604 deform. When the limiting boss 609 passes through the positioning groove 607, the ear plate 605 and the mounting plate 604 reset. The limiting boss 609 limits the ear plate 605 of the other hanger plate 601. The operation is convenient and the structure has high strength and is not easy to deform, which improves the overall structural strength. Finally, you can choose whether to install the connecting bolts 602 according to the weight of the ceiling installed on the covering keel 2. Installing bolts further increases the structural strength.

[0075] The connector 3 is composed of a first C-shaped plate 301 and a second C-shaped plate 302, which improves the structural strength of the connector 3, prevents the load-bearing keel 1 from moving, and improves the installation efficiency through the setting of the insert plate 30103 and the insertion hole 30202.
