Description

Technical Field

[0001] The utility model relates to the technical field of rail transit elevated station roof truss reconstruction construction, in particular to a comprehensive support and hanger frame fixed with a grid structure ball node. Background Art

[0002] When renovating an elevated station that has been in operation for many years, due to the early construction period, the grid structure did not reserve the conditions for the later implementation of comprehensive support and hanger brackets. At the same time, since the ball node grid can only exert external force at the ball node, and the ball node is connected to rods of different angles, it is very difficult to fix other components and ball nodes. As a result, when the comprehensive support and hanger brackets are set for the later renovation pipelines, they cannot be fixed on the grid structure, which will result in messy pipelines and poor renovation effects. Summary of the invention

[0003] The purpose of the utility model is to provide a comprehensive support and hanger fixed by a grid structure ball node based on the above-mentioned deficiencies in the prior art, and to solve the problem of fixed installation of the support and hanger when no conditions are reserved for the grid structure ball node by designing fixed components, while meeting the force requirements of the grid structure.

[0004] The purpose of this utility model is achieved by the following technical solutions:

[0005] A comprehensive support and hanger fixed by a grid structure ball node, the grid structure ball node includes a ball node and a grid chord connected to the ball node, characterized in that it includes a fixing member connected between the ball node and the comprehensive support and hanger, the fixing member includes an upper clamping plate, a lower clamping plate, and a through screw, wherein the upper clamping plate is installed above the ball node, the lower clamping plate is installed below the ball node, the upper clamping plate and the lower clamping plate are connected by the through screw, the lower side of the lower clamping plate is connected to a flange by a conversion rod, and the flange is fixedly connected to the comprehensive support and hanger.

[0006] Two upper clamping plates are arranged above the ball node. The two upper clamping plates respectively have open slots matched with the ball node. The upper clamping plates are clamped with the ball node through the open slots.

[0007] The upper clamping plate is provided with a long arc hole matching the through-screw rod.

[0008] The positions of the opening slots of the two upper clamping plates are opposite.

[0009] A support rod is arranged between the lower clamping plate and the ball node.

[0010] The utility model has the advantages of simple and reasonable structure, stable force, neat pipelines and good transformation effect; wide application range, and can fix guide and passenger service systems in addition to comprehensive support and hanger brackets. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a schematic diagram of the elevation structure of the utility model;

[0012] Figure 2 It is a top view of the node of the upper splint in the utility model. DETAILED DESCRIPTION

[0013] The following is a further detailed description of the features of the present invention and other related features through embodiments in conjunction with the accompanying drawings to facilitate understanding by technicians in the same industry:

[0014] like Figure 1-2 As shown, the marks 1-9 in the figure respectively represent: ball node 1, grid chord 2, upper clamping plate 3, through screw 4, lower clamping plate 5, support rod 6, conversion rod 7, flange 8, integrated support bracket 9.

[0015] Example: Figure 1 As shown, the integrated support and hanger fixed by the grid structure ball node in this embodiment is used to install the integrated support and hanger 9 when the elevated station is renovated. The grid structure ball node includes a ball node 1 and a plurality of grid chord rods 2. A connecting portion matching the grid chord rods 2 is provided on the ball node 1. Each grid chord rod 2 can be connected with the connecting portion at the corresponding position on the ball node 1 to form a grid structure.

[0016] Combination Figure 1 and Figure 2 As shown, in this embodiment, the ball node 1 and the integrated support bracket 9 are connected by a fixing member. Specifically, the fixing member includes two upper plywoods 3, a lower plywood 5 and a plurality of through-screws 4 therebetween. Among them, the two upper plywoods 3 are respectively provided with opening slots with opposite opening positions, and the shape and size of the opening slots match the ball node 1. The two upper plywoods 3 can be symmetrically installed above the ball node through their respective opening slots to meet the requirements of on-site rod avoidance and construction; the lower plywood 5 is arranged at the lower position of the ball node 1; a plurality of through-screws 4 are installed between the upper plywood 3 and the lower plywood 5, so that the upper plywood 3 and the lower plywood 5 are fixedly connected to form an integral structure and clamped on the ball node 1.

[0017] In this embodiment, if Figure 2 As shown, a plurality of long arc holes for installing the through screws 4 are provided on the upper clamping plate 3, and the long arc holes are arranged symmetrically in an array, so that the through screws 4 have a certain adjustment space during installation, thereby facilitating the through screws 4 to avoid the frame chord rods.

[0018] A support rod 6 is provided between the lower clamping plate 5 and the ball node 1, and a conversion rod 7 is provided below the lower clamping plate 5. The installation position of the conversion rod 7 corresponds to the position of the support rod 6, so as to realize force transmission to further improve the installation stability of the integrated support and hanger 9. A flange 8 is provided below the conversion rod 7, and the flange 8 can be connected and fixed with the integrated support and hanger 9 by bolt connection to form an integral structure, so as to realize the fixed installation of the integrated support and hanger 9.

[0019] Although the above embodiments have described the concepts and embodiments of the purpose of the utility model in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the utility model without departing from the scope of the claims, so they are not described one by one here.
