Description

Technical Field

[0001] The utility model relates to the field of industrial buildings, in particular to a truss-type lattice column. Background Art

[0002] Lattice columns are a type of building with strong bending resistance. Their characteristic is that the material area is arranged far away from the axis of inertia. This can ensure the enhanced bending performance of the component under the same axial resistance conditions and save materials. Traditional lattice columns are composed of limbs and tie rods connecting the limbs. With the increase of industrial plant crane loads or the increase of bridge pier height, the bearing capacity and lateral stiffness requirements of lattice columns increase, resulting in an increase in the cross-sectional size of the lattice columns and a decrease in the economic efficiency of the structure. Summary of the Invention

[0003] In view of this, an object of the present invention is to provide a truss-type tie-material lattice column.

[0004] The utility model provides a truss-type lattice column with the following technical solutions:

[0005] A lattice column with truss tie members includes a plurality of limbs with concrete cast inside and a plurality of truss tie members for connecting adjacent limbs. The cross-section of the lattice column is rectangular or isosceles triangular. The truss tie members connect two limbs on the long side of the lattice column. A connecting rod is provided between two limbs on one side of the short side of the lattice column. The truss tie members include an upper chord, a lower chord, and a plurality of web members provided between the upper chord and the lower chord. The upper chord and the lower chord connect the limbs.

[0006] Furthermore, the web member is arranged obliquely between the upper chord and the lower chord, and the web member is arranged in a broken line between the upper chord and the lower chord.

[0007] Furthermore, the angle between the web and the limb is 50°-70°.

[0008] Furthermore, the connecting rod is arranged horizontally.

[0009] Furthermore, the connecting rod is arranged at an angle.

[0010] Furthermore, the angle between the connecting rod and the limb column is 30°-60°.

[0011] In summary, the present invention has at least one of the following beneficial effects:

[0012] 1. At least two limbs of the lattice column are connected by truss-type tie bars. The truss-type tie bars can increase the lateral stiffness and stability of the lattice column along the corresponding sides, reduce the space occupied by the lattice column, and increase the usable space of the structure;

[0013] 2. The remaining limbs of the lattice column are connected with ordinary tie rods, which reduces the amount of steel used and improves the economy of the lattice column. The tie rod connection can enhance the coupling effect between the limbs, thereby improving the lateral stiffness and load-bearing capacity of the lattice column.

[0014] 3. The lattice columns are connected by a mixture of truss-type tie materials and ordinary tie rods, which can give full play to the advantages of their respective materials, improve the stability of the lattice columns, and extend the service life of the structure.
