[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the present utility model.

[0024] Such as Figures 1-4As shown in the figure, a cold-formed thin-walled light steel system inter-story connection component includes a floor base plate 1. A channel steel 2 is fixedly installed on the upper surface of the floor base plate 1. Partition plates 5 are fixedly installed at positions corresponding to the channel steel 2 on the bottom surface of the floor base plate 1. Channel steels 2 are also fixedly installed on the bottom surfaces of the partition plates 5. Notches 8 are opened on both channel steels 2. Installation blocks 11 are movably installed inside the notches 8. Support columns 3 are fixedly installed inside the installation blocks 11. The two ends of the installation block 11 are arranged outside the channel steel 2. Docking holes 9 are opened on both sides of the channel steel 2 where the installation block 11 is located. Installation holes are opened at positions corresponding to the docking holes 9 at both ends of the installation block 11. A shear-resistant threaded column 10 is arranged between the two ends of the installation block 11. The two ends of the shear-resistant threaded column 10 successively penetrate through the docking holes 9 opened on the channel steel 2 and the installation holes opened on the installation block 11 and extend outside the installation block 11. Threaded fastening nuts 12 are screwed on both ends of the shear-resistant threaded column 10 located outside the installation block 11. A limit nut 13 is also screwed on the shear-resistant threaded column 10 inside the channel steel 2.

[0025] During use, the channel steel 2 is connected to the floor base plate 1, the channel steel 2 is connected to the partition plate 5, and the support column 3 is connected to the installation block 11 through fasteners and are all integrally arranged. When installing the support column 3, the construction worker can correspondingly install the installation block 11 at the position where the notch 8 is located. The size of the installation block 11 matches that of the notch 8. When the installation block 11 is installed in the notch 8, the outer wall of the installation block 11 fits with the outer wall of the channel steel 2. Then, the user can place two reinforcing members 6 on both sides of the lower end of the support column 3. The triangular reinforcing member 6 can enhance the strength of the connection between the installation block 11 and the channel steel 2. After the installation block 11 and the reinforcing member 6 are assembled, the construction worker can hold one end of the shear-resistant threaded column 10 and successively pass through the installation hole opened on the installation block 11, the docking hole 9 opened on the channel steel 2, and the through hole opened on the reinforcing member 6 from one side of the floor base plate 1. When one end of the shear-resistant threaded column 10 extends into the channel steel 2, the construction worker can successively screw two limit nuts 13 on the outer wall of the shear-resistant threaded column 10 from the end of the shear-resistant threaded column 10. Then, pass the end of the shear-resistant threaded column 10 through the reinforcing member 6, the channel steel 2, and the installation block 11 again. Finally, use external tools to tighten the fastening nuts 12 screwed on both ends of the shear-resistant threaded column 10 and the two limit nuts 13 arranged inside the reinforcing member 6. On the one hand, the shear-resistant threaded column 10 can enhance the shear resistance of the channel steel 2, and on the other hand, it also makes the connection strength between the installation block 11 and the channel steel 2 higher.

[0026] As Figure 1 and Figure 2As shown, on both sides of the support column 3 inside the channel steel 2, reinforcing members 6 are movably installed. The cross-section of the reinforcing member 6 is set as a right triangle, and through holes are penetrated at positions corresponding to the docking holes 9 on the reinforcing member 6. The setting of the reinforcing member 6 can support the lower end of the support column 3, avoiding the situation that the bottom of the support column 3 breaks or tilts due to uneven stress during subsequent use.

[0027] As Figure 3 shown, on the upper surface of the mounting block 11, connecting plates 14 are fixedly installed on both sides of the support column 3. The height of the connecting plate 14 is not less than the height of the reinforcing member 6, and the outer wall of the reinforcing member 6 is in contact with the connecting plate 14. The setting of the connecting plate 14 can enhance the connection strength between the support column 3 and the mounting block 11, avoiding situations such as loosening and breaking at the connection between the support column 3 and the mounting block 11.

[0028] As Figure 1 and Figure 2 shown, an interlayer tension belt 4 is connected between two support columns 3 arranged on both sides of the floor substrate 1. Both ends of the interlayer tension belt 4 are threadedly connected with a plurality of fastening bolts 7, and threaded holes 15 are penetrated at positions corresponding to the fastening bolts 7 on the support column 3. The end of the fastening bolt 7 penetrates through the threaded hole 15 and extends to the other side of the threaded hole 15 for fastening. The fastening bolt 7 specifically consists of a head, a screw rod, and a nut used together. Pass the screw rod on the fastening bolt 7 through the threaded hole 15, and then through the cooperation of the nut, the support column 3 and the interlayer tension belt 4 can be fastened by the fastening bolt 7.

[0029] As Figure 2 shown, a plurality of fastening bolts 7 are also threadedly connected at the middle position of the interlayer tension belt 4, and the other end of the fastening bolt 7 is fastened to the corresponding position on the partition plate 5. The setting of the interlayer tension belt 4 can be used to enhance the connection strength between the two support columns 3 and the partition plate 5, preventing the two support columns 3 from tilting to one side and affecting the structural strength of the entire light steel system.

[0030] As Figure 2 shown, cushion blocks 16 are sleeved outside the fastening bolts 7 arranged at both ends of the interlayer tension belt 4, and the cushion blocks 16 are arranged between the interlayer tension belt 4 and the support column 3. The setting of the cushion blocks 16 can prevent the fastening bolts 7 from loosening, thereby ensuring the connection strength between the interlayer tension belt 4 and the support column 3.

[0031] As Figure 2 shown, a plurality of cushion blocks 16 are all elastically set, and the length of the cushion blocks 16 is not less than the distance between the interlayer tension belt 4 and the support column 3. A plurality of cushion blocks 16 are between the interlayer tension belt 4 and the support column 3. After the fastening bolts 7 are installed, both ends of the cushion blocks 16 are in a squeezed state.

[0032] Working principle of the utility model: During use, the channel steel 2 is connected to the floor substrate 1, the channel steel 2 is connected to the partition board 5, and the support column 3 is connected to the mounting block 11 through fasteners and is integrally arranged. When installing the support column 3, the construction worker can install the corresponding mounting block 11 at the position where the notch 8 is located. The size of the mounting block 11 matches that of the notch 8. When the mounting block 11 is installed in the notch 8, the outer wall of the mounting block 11 fits against the outer wall of the channel steel 2. Then, the user can place two reinforcing members 6 on both sides of the lower end of the support column 3. The triangular reinforcing member 6 can enhance the strength of the connection between the mounting block 11 and the channel steel 2. After the mounting block 11 and the reinforcing member 6 are assembled, the construction worker can hold one end of the shear-resistant threaded column 10 and sequentially pass it through the mounting hole formed in the mounting block 11, the docking hole 9 formed in the channel steel 2, and the through hole formed in the reinforcing member 6 from one side of the floor substrate 1. When one end of the shear-resistant threaded column 10 extends into the interior of the channel steel 2, the construction worker can sequentially thread two limiting nuts 13 onto the outer wall of the shear-resistant threaded column 10 from the end of the shear-resistant threaded column 10. Then, pass the end of the shear-resistant threaded column 10 through the reinforcing member 6, the channel steel 2, and the mounting block 11 again. Finally, use external tools to tighten the fastening nuts 12 threaded on both ends of the shear-resistant threaded column 10 and the two limiting nuts 13 arranged inside the reinforcing member 6. On the one hand, the shear-resistant threaded column 10 can enhance the shear resistance of the channel steel 2, and on the other hand, it also makes the connection strength between the mounting block 11 and the channel steel 2 higher. After the support columns 3 on both sides of the floor substrate 1 and the partition board 5 are installed, the construction worker can connect the two support columns 3 through the interlayer tension belt 4 and the multiple fastening bolts 7 on the interlayer tension belt 4, thereby enhancing the interlayer connection strength of the light steel system.
