Description

A lattice steel pipe tree-like column

technical field

The utility model belongs to the field of construction engineering, and relates to a support column with a space function in a steel structure.

Background technique

With the development of the economy and the progress of the society, the beauty of the three elements of architectural principles "sturdy, practical, and beautiful" has been emphasized unprecedentedly. People not only expect the architectural space to meet the basic physiological needs, but also hope that the building can have a vivid form. The various and graceful configurations of creatures in nature provide architects with rich creative materials. These reasonable prototypes of nature have many advantages and great potential for development in the field of architecture. In this case, the tree, which represents nature and green, has naturally become the object of research and imitation in the construction engineering field because of its beautiful shape and perfect tree structure.

For a special support structure such as tree structure, many researches have been carried out at home and abroad. Most of the currently disclosed tree-like structures are in the form of solid-belly structural columns, which are used to support the upper roof system, so as to realize the functions of terminal buildings, highway toll stations, supporting awnings, railway stations and A functional requirement for a large foyer.

The research shows that the lattice column in the steel structure is composed of several smaller sections, and its gross cross-sectional area is large. Compared with the solid web column, the lattice column has high bearing capacity, good longitudinal stability, and It has the advantages of high bending rigidity and small lateral deformation. At present, no one has disclosed a lattice-type steel pipe tree-like column that combines the form of a lattice-type column with a form of a tree-like structure column.

Utility model content

The purpose of the utility model is to design a lattice-type steel pipe tree-like column used in large-span space structures such as steel structures and grid structures.

The technical scheme of the utility model is: a tree-shaped column of lattice steel pipes, characterized in that it is composed of trunk riser bundles and bifurcated branch pipes; the trunk riser bundle is composed of 3-5 steel pipes The adjacent steel pipes are connected by strips; the top of each steel pipe of the trunk riser bundle is connected with a first-level bifurcated branch pipe with a diameter smaller than it, and the first-level bifurcated branch pipes are like branches. The outer fork forms a second-level branch pipe, and the second-level branch pipe branches outward step by step like a tree branch to form a third-level branch pipe; it is required that the diameter of the second-level branch pipe should be smaller than the previous one The diameter of the bifurcated branch pipes; when the bifurcated branch pipes are connected, they are welded together through multi-socket connection sleeves to form reliable nodes; finally, a lattice steel pipe tree column is formed.

When in use, the three-level bifurcated branch pipe of the tree-like column is used as a fulcrum to hinge with the roof system, thereby supporting the roof system.

Compared with the prior art, the utility model has the following advantages:

1. Steel pipe tree-like column, its shape is similar to the big tree in nature, representing nature and green, natural and beautiful in shape, reasonable in force, and special green anti-corrosion and fire-resistant paint is coated on the surface of the column in the later stage to make its appearance particularly natural Beautiful and refreshing.

2. The steel pipe tree column is light in weight, high in strength, high in bearing capacity, reasonable in force path, wide in support coverage, can greatly reduce the span of the beam, and can form a larger space with smaller rods.

3. The reasonable stress state of the tree structure is a form-effect structure state, so that all nodes are in self-balance of each force, and the rods are only subjected to axial force without bending moment, which is conducive to the stability and earthquake resistance of the structure.

4. Lattice steel pipe tree column has the advantages of lattice column: it is composed of several smaller sections, and its gross section (virtual section) has a large area. Compared with solid abdominal column, lattice column has higher High bearing capacity, good longitudinal stability, high bending rigidity, small lateral deformation (deflection), and better seismic performance.
