Abstract

The invention discloses a light steel factory post foundation suitable for sedimentation of filled-in ground and a construction method. The post foundation comprises a connecting rebar, a post bottom plate, a steel base plate, a precast cushion block and an independent under-post foundation; wherein the post bottom plate, the steel base plate, the precast cushion block and the independent under-post foundation are arranged from top to bottom in sequence; the connecting rebar comprises a top screw rod rebar, a middle screw rod rebar and a bottom drift bolt screw rod rebar; when the filled-in ground sediments, the top screw rod rebar and the middle screw rod rebar can be dismantled; the post bottom plate is jacked and restored to an original design elevation by a jack through the steel base plate, and a gap between the post bottom plate and the independent under-post foundation is filled by the precast cushion block. The light steel factory post foundation is reasonable in structure, convenient to construct, safe and reliable; height of a post bottom can be freely adjusted according to the requirement; adverse effects on construction of the conventional light steel factory post foundation and normal use of a structure caused by foundation sedimentation can be effectively solved, and the light steel factory post foundation has a good economic benefit and a time benefit in engineering construction.

Description

technical field

[0001] The invention relates to a foundation structure of a light steel factory building column, in particular to a light steel factory building column foundation adapted to the settlement of the filling foundation and a construction method for raising it after settlement.

[0002] Background technique

[0003] In the construction of new industrial areas in mountainous towns with undulating terrain, large excavations and large fillings are often required when leveling the site, and limited by the project cost and construction period requirements, it is often difficult to achieve compaction and compaction. If the steel structure factory building does not meet the compaction quality requirements If the filling area is constructed before the settlement of the filling foundation is not stabilized, the settlement will directly lead to the corresponding settlement of the foundation, thereby generating harmful secondary stress in the superstructure, and causing defo...
