Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a connection node between a bent column and a steel structure parapet wall roof truss. Background Art

[0002] In the prior art, parapet wall columns are usually welded to the outer side of the bent column, that is, welded and fixed to the outer vertical surface of the bent column. However, in some designs, the distance between the parapet wall and the roof truss is small. Welding the parapet wall column to the outer vertical surface of the bent column cannot meet the design dimension, and welding the parapet wall column to the top end sealing plate of the column will interfere with the finished hinged support. Facing such working conditions, the prior art lacks a connection node that can not only ensure the structural strength of the parapet wall column, but also avoid interference.

[0003] Therefore, how to create a new connection node between a bent column and a steel structure parapet wall roof truss is indeed one of the current important research and development subjects. Contents of the Utility Model

[0004] The utility model provides a connection node between a bent column and a steel structure parapet wall roof truss. The technical problem to be solved is to ensure the structural strength of the parapet wall column and avoid interference with the finished hinged support when the design dimension between the parapet wall column and the roof truss is small, so as to overcome the deficiencies of the prior art.

[0005] To solve the above technical problems, the utility model provides a connection node between a bent column and a steel structure parapet wall roof truss, which includes a bent column, a parapet wall column, a finished hinged support and a roof truss.

[0006] A column top sealing plate is welded to the top of the bent column, and the finished hinged support is welded on the column top sealing plate for supporting the roof truss; At a position close to the bottom of the parapet wall column, one side flange plate and part of the web plate are cut off, a first stiffening plate is horizontally welded between the end of the cut flange plate and the opposite side flange plate, a second stiffening plate is horizontally welded at a specified height above the first stiffening plate, and a first rib plate extending to the bottom end of the parapet wall column is vertically welded below the second stiffening plate, so that the second stiffening plate, the first stiffening plate and the first rib plate jointly form a "dry" shape. A column bottom sealing plate is welded to the bottom of the parapet wall column, and the column bottom sealing plate is welded and fixed to the column top sealing plate.

[0007] Further, a bracket is welded on the top surface of the finished hinged support, the bracket is in a "well" shape, and the top is provided with a semicircular groove for supporting the bottom of the lower chord of the roof truss.

[0008] Further, the upper chord and the lower chord of the roof truss are respectively welded and fixed to the parapet wall column through connecting rods.

[0009] Furthermore, the cross-section of the frame column and the top end plate are both rectangular. The outer contour dimension of the top end plate is larger than that of the frame column cross-section. A second rib is welded between the top end plate and the four sides of the frame column. There are three second ribs welded on each side, and they are arranged at equal intervals.

[0010] With this design, the present invention has at least the following advantages.

[0011] 1. This utility model sets the parapet wall column as a variable cross-section column, and welds a second stiffening plate, a first stiffening plate and a first rib plate near the bottom to reinforce the structure at the reduced cross-sectional size of the bottom of the parapet wall column, which not only ensures the structural strength but also avoids interference with the finished hinge support.

[0012] 2. The structure is reasonable, easy to construct, and suitable for widespread application. Attached Figure Description

[0013] The above is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model, the following describes this utility model in further detail with reference to the accompanying drawings and specific embodiments.

[0017] Please see Figure 1 and Figure 2 This utility model provides a connection node between a frame column and a steel structure parapet wall roof truss, including a frame column 1, a parapet wall column 2, a prefabricated hinge support 5, and a roof truss 3.

[0018] The frame column 1 is a rectangular column with a column top sealing plate 4 welded to the top. The column top sealing plate 4 is rectangular, and its outer contour dimension is larger than the cross-sectional dimension of the frame column 1, that is, the column top sealing plate 4 extends beyond the frame column 1 on all four sides.

[0019] The bottom of the column top sealing plate 4 is welded to the four sides of the frame column 1 with a total of 12 second ribs 7, and the three second ribs 7 in each side are evenly distributed.

[0020] A prefabricated hinged support 5 is fixedly welded on the column top sealing plate 4, and a bracket 6 is welded on the top of the prefabricated hinged support 5. The bracket is in a "well" shape and has a semicircular groove at the top, which is used to support the bottom of the lower chord of the roof truss 3.

[0021] The parapet column 2 adopts an I-steel, and the cross section becomes smaller near the bottom to form a variable cross-section column.

[0022] Specifically, at a position 300mm near the bottom of the parapet column 2, one side wing plate and part of the web are cut off, and a first stiffening plate 2-3 is horizontally welded between the end of the cut-off wing plate and the opposite side wing plate. A second stiffening plate 2-4 is horizontally welded at a position 200mm above the first stiffening plate 2-3. A first rib plate 2-3 is vertically welded from below the second stiffening plate 2-4, the first rib plate 2-3 extends to the bottom of the parapet column 2, and is welded and fixed with the second stiffening plate 2-4, the first stiffening plate 2-3 and the web, so that the second stiffening plate 2-4, the first stiffening plate 2-3 and the first rib plate 2-2 jointly form a "dry" shape, which is used for structural reinforcement at the variable cross-section.

[0023] The bottom of the parapet column 2 is welded with a column bottom sealing plate 2-1, that is, the column bottom sealing plate 2-1 is welded and fixed with the uncut wing plate, the web and the first rib plate 2-2, and the bottom of the column bottom sealing plate 2-1 is then welded and fixed with the column top sealing plate 4.

[0024] The upper chord and the lower chord of the roof truss 3 are respectively welded and fixed to the parapet column 2 through connecting rods 8.

[0025] On the premise of providing sufficient structural strength, the utility model effectively solves the technical problem of interference between the parapet column and the prefabricated hinged support, and has a reasonable structure, is convenient for construction, and is suitable for popularization.

[0026] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model in any form. Any simple modifications, equivalent changes or modifications made by those skilled in the art using the technical content disclosed above shall fall within the protection scope of the utility model.
