Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to a concrete lattice column supporting device. Background Art

[0002] Lattice columns are a type of building form with strong bending resistance. Their characteristic is that the material area is arranged far away from the axis of inertia. This can ensure that the bending resistance of the components is enhanced under the same axial resistance conditions and save materials.

[0003] The traditional four-limb lattice column is composed of four steel limbs and tie rods connecting the columns. With the increase of crane loads in industrial plants, the demand for the bearing capacity and lateral stiffness of the four-limb lattice column increases, resulting in an increase in the cross-sectional size of the traditional steel four-limb column, an increase in the amount of steel used, and a corresponding increase in the cost. The tonnage of equipment in existing industrial plants continues to increase, and the frequency of use continues to increase. Traditional four-limb columns often vibrate violently due to the decline of stiffness. Therefore, it is necessary to find an economical and reasonable method to improve the bearing capacity and stiffness of four-limb lattice columns.

[0004] Therefore, it is necessary to provide a concrete lattice column supporting device to solve the above problems. Summary of the invention

[0005] In view of this, the lattice column support structure of the present technical solution is filled with concrete in the column cavity and the corrugated plate cavity, and its bearing capacity and lateral stiffness are greatly improved. The transverse connecting rods and diagonal connecting rods are used in combination between the columns to further improve the structural performance of the lattice column. The construction method of the present technical solution uses on-site construction materials, which are easy to obtain and quick to construct, and are convenient for rapid construction and use.

[0006] A concrete lattice column supporting device comprises a left lattice column assembly, a right lattice column assembly and a connecting rod assembly connected between the left lattice column assembly and the right lattice column assembly; the left lattice column assembly and the right lattice column assembly have the same structure, the right lattice column assembly comprises an outer side support, an inner side support and a corrugated steel plate connected between the outer side support and the inner side support, and the corrugated steel plate, the inner side support and the outer side support are connected to form a corrugated plate cavity.

[0007] Furthermore, the corrugated plate cavity is filled with concrete, the inner pillar and the outer pillar have the same structure, the corrugated steel plate is in two pieces and the two corrugated steel plates are arranged parallel to each other between the outer pillar and the inner pillar.

[0008] Furthermore, the connecting rod assembly includes a transverse strut and a diagonal strut that are arranged parallel to each other between the left lattice column assembly and the right lattice column assembly. There are multiple transverse struts that are parallel to each other and are equally spaced.

[0009] Furthermore, the oblique support rod is arranged between two adjacent transverse support rods.

[0010] Furthermore, the outer pillar is a rectangular parallelepiped structure, the corrugated steel plate is a transverse rib corrugated steel plate, and the two sides of the transverse rib corrugated steel plate are respectively fixedly connected and installed with the outer pillar and the inner pillar.

[0011] Furthermore, the outer pillar is a cylindrical structure, and the corrugated steel plate is a longitudinal rib corrugated steel plate, and the two sides of the longitudinal rib corrugated steel plate are respectively fixedly connected and installed with the outer pillar and the inner pillar.

[0012] Furthermore, the outer side support is an I-beam, the corrugated steel plate is a transverse rib corrugated steel plate, and the two sides of the transverse rib corrugated steel plate are respectively fixedly connected and installed with the outer side support and the inner side support.

[0013] The beneficial effects of the present invention are:

[0014] 1. The pillars on the short side (width direction) of the supporting structure are made of steel pipes or steel columns with poured concrete. This structure has high bearing capacity and large lateral stiffness, which can significantly enhance the interaction between the two pillars and improve the stiffness and strength of the lattice column;

[0015] 2. The pillars on the long side (length direction) of the supporting structure are connected by connecting rods (using tie rods). The tie rods use less steel, which improves the economy of the lattice column. The tie rods can reduce the space occupancy of the lattice column and increase the usable space of the structure;

[0016] 3. The overall structure takes into account both the mechanical performance and economic performance of the lattice column, giving full play to the mechanical advantages of the lattice column in two directions. BRIEF DESCRIPTION OF THE DRAWINGS

Transverse connecting rods and oblique connecting rods are used in combination between the supports to further improve the structural performance of the lattice column. The construction method of the present technical solution uses on-site construction materials, which are easy to obtain, quick to construct, and convenient for rapid construction and use.

[0022] In this embodiment, concrete is filled in the cavity of the corrugated plate, the inner pillar 3 and the outer pillar 1 have the same structure, and the corrugated steel plate 2 is two pieces and the two corrugated steel plates 2 are arranged parallel to each other between the outer pillar and the inner pillar.

[0023] In this embodiment, the connecting rod assembly includes a transverse brace 4 and an oblique brace 5 arranged in parallel between the left lattice column assembly and the right lattice column assembly. The transverse brace 4 is a plurality of transverse braces 4 and the plurality of transverse braces 4 are arranged in parallel and at equal intervals. Transverse braces and oblique braces are arranged between the left and right lattice column assemblies. Of course, both braces can be connected with tie rods for easy connection and installation. The transverse braces 4 are arranged in parallel in multiple groups at equal intervals to improve the stability of the product.

Multiple groups of oblique braces 5 are also provided accordingly, and the two ends of the oblique brace 5 are respectively matched with two adjacent transverse braces 4 for fixed connection, so that after the connection and installation, multiple triangularly distributed small units can be formed between the transverse brace 4, the oblique brace 5 and the column, further improving the stability and force performance of the product.

The two sides of the longitudinal rib corrugated steel plate 21 are respectively fixedly connected and installed with the outer pillar and the inner pillar.

The diagonal struts are installed between two adjacent transverse struts and the two ends of the diagonal struts are welded to the ends of the transverse struts respectively; weld and install the transverse struts and the diagonal struts according to the appropriate structure (if the selected column is an I-beam structure, you only need to replace the transverse struts with transverse steel plates).
