[0025] Figures 1 to 6 This is a schematic diagram of a fixed node of an existing structure lifting bracket described in the present application. The present utility model is described in detail below in conjunction with specific embodiments and drawings.

[0026] The embodiments described herein are specific embodiments of the present invention, which are used to illustrate the concept of the present invention, are explanatory and exemplary, and should not be interpreted as limiting the embodiments of the present invention and the scope of the present invention. In addition to the embodiments described herein, those skilled in the art can also adopt other obvious technical solutions based on the claims and the contents disclosed in the specification of this application, including technical solutions that adopt any obvious replacement and modification of the embodiments described herein.

[0027] The drawings of this specification are schematic diagrams, which assist in explaining the concept of the utility model and schematically show the shapes of various parts and their mutual relationships. Please note that in order to clearly show the structure of various components of the embodiments of the utility model, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.

[0028] A schematic diagram of a fixed node of an existing structure hoisting bracket described in the utility model is as follows: Figure 1 The fixed node of the existing structure hoisting bracket includes a connecting seat 10, one end of which is connected to the existing structure, and the other end is connected to the suspension rod 20; the lower end of the suspension rod 20 is provided with a support member 30 for supporting the structure to be installed. The structure to be installed includes pipes, bridges and other components.

[0029] Figure 2 This is a disassembled diagram of the fixed nodes of the existing structure lifting bracket. Figure 3 2 is a cross-sectional view of a corresponding fixed node. The suspension rods 20 are connected to the support members 30 by bolts to form a space between the suspension rods 20 for placing components.

[0030] In the present invention, the fixed node at least includes two suspension rods 20 and two connecting seats 10, so as to reliably connect the support member 30 to the existing structure through the suspension rods 20.

[0031] The fixed node provided by the utility model abandons the connection method of using expansion screws in the prior art, avoids the damage of the expansion screws to the existing structure, and effectively improves the reliability of the connection of components.

[0032] In order to ensure the reliability of the connection, the connection between the suspension rod 20 and the connection seat 10 needs to be locked with a nut 60.

[0033] Figure 4It is a schematic diagram of a connecting seat 10 provided in an embodiment of the utility model. The connecting seat 10 is a rectangular frame structure, on which a vertical fixing hole 10a is arranged. The end of the suspension rod 20 is provided with a thread, and the suspension rod 20 is threadedly connected to the fixing hole 10a of the connecting seat 10.

[0036] In order to increase the reliability of the connection between the connection base 10 and the existing structure, it is necessary to increase the roughness of the upper surface of the second extension plate 12. In some embodiments, the upper surface of the second extension plate 12 is configured with a concave-convex structure 12a to increase the friction coefficient of the surface.

[0037] Furthermore, the concave-convex structure 12 a is a columnar body, which is vertically extended upward along the second extension plate 12 .

[0038] As an embodiment of the present invention, the cross-sectional shape of the concave-convex structure 12a is circular, rectangular and / or triangular. Figure 5 In the illustrated embodiment, the cross-sectional shape of the concavo-convex structure 12a is circular, and the vertical height of the concavo-convex structure 12a is less than or equal to 2 mm.

[0039] Figure 6 is a schematic diagram of a fixed node provided in another embodiment of the present invention. In this embodiment, the fixed node further includes a pad 50 , which is disposed on the upper surface of the second extension plate 12 .

[0040] Furthermore, the pad 50 is provided with a mounting hole 50a, which is arranged concentrically with the fixing hole 10a to ensure the reliability of the fixing of the pad 50 and prevent it from moving between the connecting seat 10 and the existing structure to affect the reliability of the fixing of the two.

[0041] As one aspect of this embodiment, the pad 50 is made of hard rubber material. Preferably, the pad 50 is made of fluororubber, and the thickness of the pad 50 is 1-3 mm.

[0042] In the present invention, the support member 30 is an angle steel or a square steel, which is threadedly connected to the suspension rod 20 and locked by a nut 60. Pipes, bridges and other components used in the construction process can be placed above the support member 30.

It avoids the damage of existing expansion screws to the existing structure and effectively ensures the connection strength of the structural parts of the pipeline and / or bridge waiting to be installed.

[0044] The present utility model is not limited to the above-mentioned implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the protection scope of the present utility model.
