[0024] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0025] like Figures 1-4 As shown, a pre-embedded vertical cable tray through-floor fixing device includes a single section 3, which is a vertically arranged cylindrical section with vertically connected upper and lower ends, both of which are rectangular.

[0026] A partition 2 is provided inside the segment 3. The partition 2 is arranged perpendicular to the length direction of the segment 3, that is, the partition 2 is perpendicular to both long sides of the segment 3. The partition 2 serves both as a divider and a support inside the segment 3.

[0027] A fixing frame is fitted onto the outside of the segment unit 3, and the fixing frame is fixed to the outer wall of the segment unit 3. The fixing frame consists of two first support rods 6 and two second support rods 7, which are spaced apart. The first support rods 6 are fixed to the outer wall of the segment unit 3 in the width direction, and the second support rods 7 are fixed to the outer wall of the segment unit 3 in the length direction. The length of the first support rod 6 is greater than that of the segment unit 3, and the length of the second support rod 7 is greater than that of the segment unit 3. Therefore, both ends of the first support rods 6 and the second support rods 7 protrude from the segment unit 3.

[0028] A connecting plate 5 is arranged on each of the two end faces of the segment unit 3 in the width direction. The upper part of the connecting plate 5 is fixed to the outer wall of the segment unit 3, and the lower part of the connecting plates 5 on both sides extends downward to the lower part of the segment unit 3. A set of plate connecting holes 8 is also opened on the lower part of the connecting plates 5 on both sides, and a set of segment connecting holes 4 is also opened on the upper part of each of the two end faces of the segment unit 3 in the width direction. The segment connecting holes 4 on the same side are located directly above the corresponding side plate connecting holes 8.

[0029] The specific working process and working principle are as follows:

[0030] According to the preset thickness of the floor 9, the corresponding height of the node monomer 3 is selected, and the height of the node monomer 3 is greater than the thickness of the floor 9. Then, the two oppositely arranged connecting plates 5 are fixed at the lower part of the node monomer 3. Two first support rods 6 and second support rods 7 with appropriate lengths are selected, and the two first support rods 6 and second support rods 7 are fixed with the corresponding end faces of the node monomer 3, respectively.

[0031] According to the positions and contours of the two side connecting plates 5, holes are opened on the pouring formwork, so that the two side connecting plates 5 extend through the pouring formwork to the lower part of the connecting plate 5. And the foam filling 1 is placed inside the node monomer 3 to avoid the concrete pouring into the node monomer 3 when the concrete is poured.

[0032] The node monomer 3 is fixed by the first support rods 6 and the second support rods 7 around the node monomer 3 and the binding steel bars in the pouring formwork. Finally, the concrete is poured, and the floor 9 is formed after the pouring is completed. Finally, the formwork is removed, and the first support rods 6, the second support rods 7 and the node monomer 3 are jointly poured inside the concrete.

[0033] When the bridge connection is carried out subsequently, the bridges above and below the floor 9 are directly connected with the upper and lower ports of the node monomer 3. After the bridge above the floor 9 is connected with the node monomer 3, the bridge is fixed through the node connecting hole 4 at the upper part of the node monomer 3. After the bridge below the floor 9 is connected with the node monomer 3, the bridge is fixed through the plate connecting hole 8 at the lower part of the connecting plate 5. Finally, the channel for accommodating the cable is formed, as shown in Figure 5 .

[0034] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to obtain equivalent embodiments. However, any simple modification, equivalent change and modification of the above embodiments made according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
