Assembled under-column foundation

Abstract

The invention relates to an assembled under-column foundation. The assembled under-column foundation comprises a box body formed by splicing weather-resistant steel plates, wherein vertical tie bars are arranged in the box body; horizontal reinforcing ribs which are arranged in a crisscross mode are arranged in the box body; a lower-layer anchor plate, connecting sleeves and anchor bars are arranged in the box body; the connecting sleeves are welded to the lower end of the lower-layer anchor plate; the anchor bars are in threaded connection with the connecting sleeves; bolt connecting holes used for being connected with stand columns are formed in the lower-layer anchor plate; a PVC pipe or a steel pipe is arranged in the box body in a penetrating mode; and concrete is poured into the boxbody. The assembled under-column foundation can be produced in batches in a factory according to standard parts, the weather-resistant steel plates are resistant to corrosion in use, paint coating andother anti-corrosion measures are not needed, and the durability is good. The assembled under-column foundation has the advantages that the bearing capacity is large, manufacturing, mounting and construction are easy and fast, energy saving and environmental friendliness are achieved, materials are saved, the construction progress is accelerated, the construction period is shortened, and turnoveruse is facilitated.

Description

technical field [0001] The invention relates to the technical field of foundations, in particular to an assembled foundation under a column. Background technique [0002] A large number of columns are involved in the construction of municipal bridge structures, and most of the columns use extended foundations. Conventional extended foundations are mostly made of on-site support formwork pouring concrete, and a lot of stressed steel bars are arranged in the concrete. If they are used in places with heavy loads or poor geological conditions, the overall size needs to be large. There are many on-site construction techniques for conventional extended foundations. , is easily affected by the environment, the quality is not guaranteed, the production time is long, the form is fixed after the production is completed, the versatility is poor, the transportation is difficult, and the degree of assembly is low.
