Embodiment 1

[0050] Embodiment one sees Figure 1-4As shown, a steel lattice column structure with four limbs includes a steel lattice column, and the steel lattice column includes a column limb group, a horizontal web member group, a strut group and a shoulder platform.

[0051] The column limb group includes four column limbs 1 of equal height, which are respectively arranged at the four corners of the steel lattice column.

[0052] The horizontal web rod groups include four groups, which are arranged between adjacent column limbs 1. The horizontal web rod groups are respectively provided with one group on the four sides of the steel lattice column. Each group of horizontal web rod groups includes four groups along the column limb 1. The horizontal webs 2 are arranged in layers at equal intervals in the height direction, the number of adjacent two groups of horizontal webs 2 is the same, and the horizontal webs 2 of each layer are arranged at equal height positions one by one, and the tw...

Embodiment 2

[0066] Embodiment two see Figure 5-6 As shown, a steel lattice column structure with four limbs is different from the first embodiment in that it also includes a cup base 13 connected to the steel lattice column, and the cup base 13 is provided with different holes for the column limbs 1 to embed. Through the column leg groove 8, the bottom of the column leg 1 is inserted into the column leg groove 8, the column leg concrete includes the bottom concrete 9 and the top concrete 10, and the pouring height of the bottom concrete 9 is such that the column leg 1 is embedded in the cup The range of the mouth foundation 13, and the surface of the column limb 1 in this range is welded with steel column studs 11, and the gap between the column limb 1 and the column limb groove 8 of the cup mouth foundation 13 is filled with grouting concrete 12, and the The grouting concrete 12 is micro-expansion fine stone concrete one level higher than the foundation concrete strength level of the cu...

Abstract

The invention discloses a four-limb steel latticed column structure and a construction method thereof. The four-limb steel latticed column structure comprises a steel latticed column, wherein the steel latticed column comprises column limb sets, horizontal web member sets, supporting rod sets and a shoulder platform, the horizontal web member sets are arranged on the four sides of the steel latticed column respectively, the two ends of each horizontal web member are fixedly connected with column limbs on the two sides, the horizontal shoulder platform is fixedly connected to the top of the four-limb steel latticed column structure, the supporting rod set comprises a set of supporting rods equal in length, column top supporting rods are arranged at the included angle connecting positions of the shoulder platform and the column limbs, and column body supporting rods are arranged at the included angle connecting positions of the column limbs and the horizontal web members. According to the four-limb steel latticed column structure, oblique web members are omitted, the machining and manufacturing difficulty can be reduced, it is ensured that large pipelines such as air pipes pass through, meanwhile, the supporting rods are arranged at the joints of the horizontal web members and the column limbs, the structural rigidity can be improved, the anti-seismic performance can be enhanced, the overall stability of the structure can be improved, and compared with the prior art, adjustment can be conducted at any time during construction and hoisting, precision is high, and the construction quality is effectively controlled.

Description

technical field [0001] The invention relates to a steel lattice column, in particular to a steel lattice column structure with limbs and a construction method thereof. Background technique [0002] The steel lattice column with four limbs has the characteristics of obtaining a larger section bending stiffness with a smaller diameter column limb, and the column limb is mainly subjected to axial force, which has good overall stability, saves steel, high bearing capacity, and high structural rigidity, etc. Advantages, widely used in large-scale projects. [0003] Existing steel lattice columns with four limbs are generally composed of column limbs, transverse web bars and diagonal web bars. The conventional steel lattice column construction method is to fill the bottom with fine stone concrete first, then stand the column on the leveling layer, and pour and vibrate the surrounding area after correction. [0004] But there are the following problems in its use: [0005] 1. Th...
