Description

Inclined steel tube concrete tree column platform canopy

technical field

The utility model relates to a platform canopy structure, in particular to an inclined steel tube concrete tree column platform canopy structure.

Background technique

Generally speaking, when the canopy is built, most of them are flat-roofed, especially for steel structures or fiberglass structures, such designs are often used. Such designs can achieve strong aesthetics, but they also show On the downside, its drainage system tends to suffer. When this structure suffers from heavy rain or snow, the accumulated rain and snow will often generate huge loads, which will increase the burden on beams, columns and other components. In addition, rainwater will corrode the pillars and other components below, which will reduce the service life of the awning. In order to solve the drainage problem, the two rows of columns of the platform canopy are inclined at different angles, which can make the canopy naturally produce a certain slope, and then realize organized drainage. The common platform canopy, the structure will be affected by the wind load generated by the train entering and leaving the station, the self-weight, the inertial force generated by the earthquake, etc. These loads will eventually be transmitted to the column, resulting in a large bending moment at the bottom of the column, making the cost of the foundation Increase. Using the inclined column platform canopy structure, the column body is inclined to the outside, and its own gravity can balance part of the bending moment at the bottom of the column. In this way, the bending moment of the column control section can be reduced during the design, and the cost of the column body and the foundation can be reduced. In addition, under the earthquake, compared with the traditional upright columns, the columns inclined in two directions can effectively resist the horizontal inertial force generated by the earthquake

In recent decades, CFST columns have been used more and more widely in civil engineering, especially in the field of building structures. Concrete-filled steel tube columns use the advantages of steel and concrete at the same time, so that the overall performance of the combination of the two materials is significantly better than the simple superposition of the performance of the two, greatly improving its comprehensive performance. As a station building column, the concrete column is not as beautiful as the section steel, and the pure steel structure is restricted by its stability. Therefore, the steel pipe concrete column that avoids the shortcomings of the two came into being.

For complex superstructures, a beam-shaped column head can provide multiple fulcrums, which can disperse the internal force of the original node, expand the supporting surface, and reduce the burden on the node. In addition, in earthquake-prone areas, the joint area is often severely damaged. Steel structure joints are convenient for factory prefabrication and post-disaster repair work. The joint replacement is convenient and efficient, and no or only a small amount of on-site wet work is required. Combining the above reasons, the canopy of the inclined steel tube concrete tree column platform came into being.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

As shown in Figures 1, 2 and 3, an inclined steel tube concrete tree column platform canopy includes a canopy frame and a rain shield covering the top of the canopy frame, and the feature is that the canopy frame includes a column 3. The longitudinal truss 1 and the transverse truss 2 fixed on the top of the column 3; the longitudinal truss 1 and the transverse truss 2 are connected from head to tail through the column head 4 to form a rectangular frame, and the column head 4 adopts a tree-like column head for connecting the longitudinal truss 1, Horizontal trusses 2 and columns 3, each of the tree-shaped column heads connects a column 3, a horizontal truss 2 and at least one longitudinal truss 1, and a plurality of tree-shaped column heads are combined to form a longitudinal truss in width and a length of several horizontal trusses Scaffolding: the uprights on both sides of the transverse truss 2 are all inclined towards the center of the transverse truss 2, and the inclination angle of the uprights on one side is greater than that on the other side.

In this embodiment, the columns 3 all adopt the same steel tube concrete structure.

In this embodiment, the column head 4 is connected with the longitudinal truss 1 , the transverse truss 2 and the column 3 by welding.

In this embodiment, the inclination angle is the angle between the column 3 and the vertical line, the angle on one side is 20 degrees, and the angle on the other side is 15 degrees.

In this embodiment, the tree-like stigma is divided into a lower chord branch and an upper chord branch, the lower chord branch includes a lower chord anchor 5 and a plurality of lower chord branches 6 integrally formed with the lower chord anchor and spreads outward, and the upper chord branch includes an upper chord anchor 7 and a number of upper string branches 8 that are integrally formed with the upper string anchors and spread outward, wherein the lower string anchors 5 are poured in concrete and prefabricated together with the columns, and the upper string anchors 7 are welded to one of the lower string branches 6, and the upper string branches 8 are connected by welding Horizontal truss 2 or vertical truss 1, the tree-like column head greatly reduces the burden on nodes and increases the aesthetic effect. Specifically: the function of the lower chord anchor is to transmit the shear force of the horizontal or longitudinal truss to the column, and convert it into the axial force and bending moment borne by the column. The lower chord anchor is poured in concrete to ensure the connection between the column head and the column, so that the column and the column body will not fall off. One branch of the lower chord anchor is used for welding with the upper chord anchor, while the other branches are used to connect with its adjacent transverse or longitudinal lower chord. The connection with the truss is that the upper and lower chord branches on the same side are respectively connected to the upper and lower ends of the truss. The principle of reducing the burden on nodes: For general beam-column nodes (or truss nodes), the shear force transmitted by the beam will generate huge stress at the node, so when disasters such as earthquakes occur, the nodes are often damaged first . This kind of column head node transmits the shear force transmitted from the upper and lower chords of the horizontal or longitudinal truss to the column respectively, instead of directly transmitting it at one time, so the effect of reducing the burden on the column head node can be achieved.

Build process:

1. Prepare the foundation of the column in advance. The foundation can be in the form of an independent foundation under the column, and the foundation material can be reinforced concrete or pure steel structure. Because the uprights are covered with steel pipes, the uprights can be connected with steel more conveniently. After the column hoisting construction is completed, the fine stone concrete is used for caulking;

2. After the joint-filling concrete has a certain strength and the settlement of the column is uniform, the lower chord branch of the column head is welded to the lower chord of the two longitudinal trusses and the adjacent horizontal lower chord to form a rectangular frame. Weld the upper chord branch of the column head, and connect the upper chord branch with the corresponding truss upper chord;

3. Follow the above steps to carry out construction until all the rods are installed.

The above is only the preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and deformations can also be made. And deformation should also be regarded as the protection scope of the present utility model.
