Connection node structure between concrete hanging columns and steel frame columns on the roof of prefabricated substation

Abstract

This utility model discloses a connection structure between a prefabricated substation roof concrete hanging column and a steel frame column. The steel frame column at the connection point with the roof has a steel frame beam inside, with stiffening plates corresponding to the lower flanges of the beams. Multiple steel sleeves are evenly welded to the stiffening plates. The reinforcing bars of the concrete hanging column are connected to these steel sleeves, and the concrete hanging column is integrally cast with the roof slab. This utility model completely avoids the risk of water leakage at the joint between the hanging column and the concrete roof slab, which is unavoidable due to the incompatibility of the two materials.

Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation roofs, and more specifically, to a connection node structure for concrete hanging columns and steel frame columns on the roof of a prefabricated substation. Background Technology

[0002] Currently, the method for roof-mounted wiring in prefabricated substations involves directly penetrating the prefabricated steel frame columns through the roof concrete slab, with wiring points set on the steel columns for direct wiring. This method creates a weak point at the joint between the steel frame column and the concrete slab, posing a significant risk of leakage should the roof waterproofing fail. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a connection node structure for the concrete hanging column and steel frame column on the roof of a prefabricated substation.

[0004] This utility model discloses a connection structure between a concrete hanging column and a steel frame column on the roof of a prefabricated substation. The structure is achieved through the following technical solution: a steel frame column is provided, and a steel frame beam is installed inside the steel frame column at the connection between the steel frame column and the roof. A stiffening plate is provided on the lower flange of the steel frame beam, and multiple steel sleeves are uniformly welded on the stiffening plate. The reinforcing bars of the concrete hanging column are connected to the steel sleeves, and the concrete hanging column and the roof floor slab are integrally cast.

[0005] The sleeve welding position meets the anchorage length requirements of the concrete hanging column reinforcement.

[0006] Compared with the prior art, the beneficial effects of this utility model are: This invention replaces steel columns with concrete columns for cable hanging. The concrete column is cast uniformly with the concrete roof slab, avoiding the formation of joints and the risk of leakage. Furthermore, cable hanging columns are typically installed on the roof of GIS equipment rooms, which have high ceilings, making leak repairs difficult and potentially affecting the normal operation of electrical equipment.

[0007] This invention can completely avoid the risk of water leakage at the joint between the hanging post and the concrete roof panel, which is unavoidable due to the difference between the two materials. Attached Figure Description

[0009] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this utility model pertains. The terminology used in this specification of the utility model is for the purpose of describing particular embodiments only and is not intended to limit the utility model.

[0010] like Figure 1-2 As shown, this utility model includes a steel frame column 1, a steel frame beam installed inside the steel frame column at the connection between the frame column and the roof, a stiffening plate 2 correspondingly installed on the lower flange of the steel frame beam, and multiple steel sleeves 3 evenly welded to the stiffening plate; the concrete hanging column reinforcement 4 is connected to the steel sleeves, and the concrete hanging column is integrally cast with the roof floor slab. The welding position of the sleeves meets the anchorage length of the concrete hanging column reinforcement.

[0011] The implementation process of this utility model is as follows: A conversion is performed at the connection between the top beam and column of the box-type steel column. During the factory processing of the steel frame column, steel sleeves are welded to the inner wall of the box-type steel frame column according to design requirements. After on-site hoisting and positioning, the reinforcing bars of the concrete hanging column are connected to the sleeves, and the concrete hanging column is integrally cast with the roof slab. This converts the box-type steel frame column into a concrete column.

[0012] The above description is only a preferred embodiment of the present utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
