A kind of seismic isolation foundation structure and construction method of steel pipe concrete column support of masonry building

Abstract

The invention discloses a masonry building concrete filled steel tubular column pedestal shock isolation foundation structure and a construction method thereof. The masonry building concrete filled steel tubular column pedestal shock isolation foundation structure comprises a building peripheral outer wall shock isolation foundation and a building peripheral inner wall shock isolation foundation; the building peripheral outer wall shock isolation foundation is composed of a lower part structure, a peripheral upper supporting beam and an upperpart structure; the peripheral upper supporting beam and the upperpart structure are arranged above the lower part structure; and shock isolation devices are arranged between the peripheral upper supporting beam and the lower part structure as well as between a middle upper supporting beamand the lower part structure respectively. The construction method comprises the following steps: arranging the shock isolation devices; arranging the upper supporting beams; prefabricating a shock isolation device component; excavating earthwork; detecting the lower part structure; carrying out location and line laying of the shock isolation devices; installing the shock isolation devices; carrying out reinforcement operation on the shock isolation devices; constructing the upper supporting beams; filling sealing materials; constructing concrete composite slabs; and constructing earth-retaining walls and scattered-water concrete. The masonry building concrete filled steel tubular column pedestal shock isolation foundation structure is low in construction cost and ensures the service life when reducing the backfilling engineering quantity of an indoor foundation.

Description

technical field [0001] The invention belongs to the technical field of building shock isolation, and in particular relates to a shock-isolation foundation structure and a construction method of a steel pipe concrete column support of a masonry house. Background technique [0002] At present, the commonly used seismic isolation foundations in house seismic isolation technology include: multi-layer rubber bearing isolation, multi-layer rubber bearing isolation with lead core, friction-sliding multi-layer isolation and resistor isolation, etc. Seismic technology has very special requirements on materials and high construction costs, which will greatly increase the cost of housing construction. [0003] The Chinese patent with the publication number CN201106231Y discloses a shock-isolation device for concrete-filled steel tube columns. On both ends of the steel-filled steel tube concrete column, upper seals, lower seals and lead pads are respectively fixed on the two ends of the...

Problems solved by technology

[0004] In addition, the existing seismic isolation devices have special requirements on materials. During the construction process, except for the seismic isolation device itself, which is a prefabricated product and installed on site, most of the other parts are cast-in-place concrete.
