[0031] As Figure 1 described, in the present preferred embodiment, the cable bracket assembly of the trestle bridge deck includes a bracket 1, an I-beam support 2, and a base 3. Now, each part feature will be described in detail with reference to the drawings.

[0032] As Figure 3 shown, the base 3 is a U-shaped structure composed of several steel plates welded together, including a first horizontal bottom plate 31, a second horizontal bottom plate 32, side plates 33, a bolt assembly 34, and a second stiffening plate 35. The first horizontal bottom plate 31 and the second horizontal bottom plate 32 are arranged facing each other in the vertical direction and at least one end is aligned, corresponding to the two flange plates of the U-shaped structure. The top of the side plate 33 is perpendicularly welded to the first horizontal bottom plate 31, and the bottom is perpendicularly welded to the second horizontal bottom plate 32. The height of the side plate 33 is equal to the thickness of the trestle bridge deck 4, so that the base 3 can be nested on the surface of the trestle bridge deck 4 from the side. At one end of the first horizontal bottom plate 31 and the second horizontal bottom plate 32 close to the U-shaped opening, a relief hole is provided respectively, and the two relief holes are aligned in the vertical direction. As Figure 1 shown, during on-site installation, the base 3 is sleeved on the surface of the trestle bridge deck 4 from the side until the side plate 33 is closely attached to the side of the trestle bridge deck 4; then, along the alignment axis of the two relief holes, the trestle bridge deck 4 is drilled through; subsequently, a set of bolt assemblies 34 is passed through between the first horizontal bottom plate 31 and the second horizontal bottom plate 32, and by tightening the bolt assemblies 34, the base 3 can be fixed on the trestle bridge deck 4.

[0033] In this preferred embodiment, the vertical support is a section of I-beam arranged vertically. The first horizontal base plate 31 extends a section away from the U-shaped opening and is perpendicularly welded to the bottom of the I-beam support 2. The web 22 of the I-beam support 2 is parallel to the extending direction of the first horizontal base plate 31, that is, perpendicular to the side plate 33. To improve the load-bearing performance of the base 3, a second stiffening plate 35 is provided below the extending section of the first horizontal base plate 31. The second stiffening plate 35 and the web 22 of the I-beam support 2 are in the same vertical plane. The top of the second stiffening plate 35 is perpendicularly welded to the first horizontal base plate 31, and the side is perpendicularly welded to the side plate 33.

[0034] As Figure 4 shown, in another preferred embodiment, the base 3 does not need to be provided with the extending section of the first horizontal base plate 31 and the second stiffening plate 35, and also has the same function. Correspondingly, the top of the side plate 33 is welded to one end of the first horizontal base plate 31, and the bottom is welded to the same-side end of the second horizontal base plate 32. Obviously, at this time, the connection position of the I-beam support 2 and the first horizontal base plate 31 is closer to the opening side of the U-shaped structure than the side plate 33.

[0035] As Figure 1 shown, in this preferred embodiment, the I-beam support 2 further includes a flange support plate 21. The flange support plate 21 is a flange plate on the outer side of the I-beam support 2. There is a distance left between the bottom of the flange support plate 21 and the end of the extending section of the first horizontal base plate 31 for the bracket 1 to stay. Two notches 211 are provided on both sides of the flange plate support 21, and the two notches 211 are at the same height. To enable the bracket 1 to be sleeved on the flange support plate 21, the height from the two notches 211 to the first horizontal base plate 31 is greater than the overall height of the bracket 1.

[0036] As Figure 2As shown in the figure, the bracket 1 includes a tray 11, a first clamping member 12, a second clamping member 13, a vertical connecting plate 14 and a first stiffening plate 15. The tray 11 is a strip-shaped steel plate, with one end bent upward to provide a limit for the cable to prevent it from slipping off the end. The other end of the tray 11 is welded to the first clamping member 12 in the same plane, that is, the tray 11 and the first clamping member 12 are butt-welded laterally. The second clamping member 13 is spaced from the first clamping member 12 in the vertical direction and is connected by the vertical connecting plate 14 in the middle: the vertical connecting plate 14 is perpendicular to the length direction of the tray 11, with the top welded to the first clamping member 12 and the bottom welded to the second clamping member 13. As an equivalent alternative to this preferred embodiment, the top of the vertical connecting plate 14 can also be welded to the bottom of the tray 11. To improve the stiffness, the bracket 1 is provided with the first stiffening plate 15 in the vertical plane. The top of the first stiffening plate 15 is perpendicularly welded to the tray 11, and the side is perpendicularly welded to the vertical connecting plate 14.

[0037] As shown in Figures 1 and Figure 5 As shown in the figure, the first clamping member 12 is provided with a first slot 121 penetrating in the thickness direction. To cooperate with the I-beam support 2, the first slot 121 is a semi-closed T-shape. The first slot 121 is axisymmetric about the length direction of the tray 11, and the opening is provided on the side away from the tray 11. For the convenience of description, a section of the slot parallel to the axis of symmetry is defined as the longitudinal slot section, and a section of the slot perpendicular to the axis of symmetry is defined as the transverse slot section. The width of the longitudinal slot section is greater than the net distance between two notches 211 on the flange support plate 21; the width of the transverse slot section is equal to the thickness of the flange support plate 21, and the length is equal to the width of the flange support plate 21. A second slot 131 is provided on the second clamping member 13, and the opening direction of the second slot 131 is the same as that of the first slot 121. The second slot 131 is open, and the minimum width is equal to the width of the flange support plate 21, and it can be sleeved on the surface of the flange support plate 21 without passing through the notch 211.

[0038] To ensure that the tray 11 remains horizontal when the bracket 1 is sleeved on the flange support plate 21, the boundaries of the first slot 121 and the second slot 131 on the side away from the opening are aligned in the vertical direction, that is, the horizontal distances from the two boundaries to the vertical connecting plate 14 are equal.

[0039] As Figure 1As shown, the first card member 12 passes through the notch 211 from the horizontal direction through the first card slot 121. When the first card member 12 abuts against the flange support plate 21, lower the first card member 12 to make it leave the height where the notch 211 is located. At the same time, the second card member 13 is clamped on the surface of the flange support plate 21 through the second card slot 131, and the bracket 1 is sleeved on the I-beam support 2. Under the action of gravity, the bracket 1 can take the I-beam support 2 as a track and slide down in the vertical direction. Since there is enough space left between the bottom of the flange support plate 21 and the end of the first horizontal bottom plate 31, when the bracket 1 slides down to the bottom of the flange support plate 21, the second card member 13 abuts against the first horizontal bottom plate 31, and the bracket 1 maintains a stable state in the vertical direction, so as to realize the support of the cable. In this position state, since the size of the first card slot 121 fits the flange support plate 21, the flange support plate 21 provides horizontal limit for the upper part of the bracket 1; since the width of the second card slot 131 fits the flange support plate 21, the flange support plate 21 can limit the left-right swing of the bottom of the bracket 1.

[0040] A guardrail 5 is connected to the upper part of the I-beam support 2. The I-beam support 2 serves as a structural column of the guardrail 5 and provides a vertical support function. Therefore, in this preferred embodiment, the bracket 1 can be directly connected to the structural column of the guardrail 5 without using an additional steel section member as a connection medium. When removing the guardrail 5, lift the bracket 1 in the vertical direction to make the first card member 12 and the notch 211 at the same height, and then move the first card member 12 in a direction away from the flange support plate 21, and the bracket 1 can be removed from the I-beam support 2.

[0041] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention who makes non-substantive modifications to the present invention using this concept shall fall within the scope of infringement of the protection of the present invention.
