Problems solved by technology

[0006] Aiming at the above-mentioned deficiencies in the prior art, the present invention solves the problem that the column base of the light steel factory building on the existing filling foundation will cause the elevation of the bottom of the column to decrease with the settlement of the filling foundation, resulting in deformation, cracking or cracking of the upper structure and buildings of the light steel factory building. Instability will seriously affect the safety of building structures, and the use of existing technologies will result in high maintenance costs, and a light steel factory building column foundation that is suitable for the settlement of the fill foundation is provided

Embodiment 1

[0040] Embodiment 1: as figure 1 As shown, a light-steel workshop column foundation adapted to the settlement of the filling foundation includes a column bottom plate 1, a steel backing plate 2, a prefabricated spacer 3, and an independent foundation 4 under the column (the independent foundation under the column Foundation 4 is generally made of concrete or reinforced concrete material) and connecting steel bar, and described connecting steel bar comprises top screw bar steel bar 5 and bottom anchor screw bar bar 6, and described top screw bar bar 5 and bottom anchor bar bar bar 6 pass through connecting sleeve 7. The detachable connection is connected with a mechanical sleeve during specific implementation, which is more stable; the I-steel steel column 8 of the light steel factory building is fixedly connected with the column bottom plate 1. Described prefabricated spacer 3 is steel plate, cement mortar spacer or concrete spacer, makes the intensity of prefabricated spacer ...

Embodiment 2

[0052] Example 2, such as figure 2 As shown, there are a plurality of prefabricated pads, and the connecting steel bars include top screw bars, middle screw bars 9, and bottom anchor screw bars, and the top screw bars, middle screw bars 9, and bottom anchor bar bars are connected by The sleeve threaded connection is connected by a mechanical sleeve during specific implementation, which is more stable.

[0053] In the case of large foundation settlement, add or replace the middle screw reinforcement with appropriate length according to the needs, so that when filling the prefabricated pad (pad), the middle screw reinforcement can be connected while filling the prefabricated pad (pad) ,More convenient. After the ground subsidence occurs, the column bottom plate of the I-steel column of the light steel factory building is lifted first, and then the hole prefabricated concrete pad (or pad) is used to fill the resulting independent foundation under the column and the column botto...

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...
