Problems solved by technology

It can be seen from the figure that the webs cannot work alone, and need to cooperate with the surrounding concrete. The accessories are also composed of multiple webs. Now the installation is complicated and difficult, and the fiber material is a new material. The price Higher, resulting in increased cost and less energy consumption

Embodiment 1

[0046] Such as figure 1 As shown, a kind of anti-horizontal lateral force lattice column includes limb parts, embellishment parts and beams 6, wherein the beams are H-shaped steel beams, and the limb parts include steel columns 10; wherein, the steel columns 10 It is a square rectangular tube pillar, and the upper and lower ends of the steel column 10 are respectively welded with steel sheet 2 and steel sheet 4, and the lower flange of the crossbeam 6 is connected with bolt 1 and bolt 5 through steel sheet 2 and steel sheet 4 respectively. It is fixedly connected with the foundation 11, and the three-dimensional stereogram of the H-shaped steel beam is as follows figure 2 As shown, the three-dimensional stereogram of the square rectangular tube pillar is as follows image 3 shown;

[0047] The accessory part includes the curved steel bars 7 between the square and rectangular tube pillars and the elongated steel sheet 8 for connecting two curved steel bars 7. The three-dimen...

Embodiment 2

[0054] A kind of anti-horizontal lateral force lattice column. The difference from Embodiment 1 is that the bolts 5 are used to connect the steel sheet 4 at the lower end of the rectangular tube pillar and the upper flange of the H-shaped steel beam, that is, the horizontal lateral force-resistant lattice Columns are used on the second floor or above.

Embodiment 31

[0056] A horizontal lateral force resistant lattice column is different from Embodiment 1 in that there are four contact points 9 between the elongated steel sheet 8 and the curved steel bar 7 .

Abstract

The invention provides a horizontal-lateral-force-resistant lattice column, which comprises a limb member part, a pendant member part and a cross beam part, wherein the limb member part comprises steel upright posts; and the pendant member part comprises bent steel bars arranged among the steel upright posts. When bearing the horizontal force, the horizontal-lateral-force-resistant lattice column provided by the invention has sufficient load bearing capability and deformation-resistant capability; a good lateral-force-resistant energy consumption effect can be achieved through the pendant member deformation; meanwhile, the steel consumption is reduced; and the building cost is reduced. The lattice column has a simple and compact form, and is suitable for industrialized production and in-site assembling; the quality can be easily ensured; and the construction period can be greatly shortened. The in-site construction quantity is reduced, so the construction waste is reduced, the construction noise and the dust pollution are reduced, and important environment protection significance is realized.

Description

technical field [0001] The invention relates to a lattice column, in particular to a horizontal lateral force resistant lattice column. Background technique [0002] With the development of the global economy, especially with the rapid development of my country's construction economy in recent years, there are more and more economically safe steel structure residential projects. At the same time, the environment in which steel structural components are located is becoming more and more complex. Therefore, the requirements for lattice columns used in steel structure residences are getting higher and higher, and lattice columns are an important part of steel structure residences, and unreasonable lattice column forms are an important reason for the increase in economic costs. One of the main reasons for the excessive use of steel in steel structure houses is that in some cases it is not necessary to increase the cross-sectional dimensions of lattice columns and accessories, s...
