Supporting steel pipe stand column and fire pool wall connecting structure and construction method

Abstract

The invention relates to a supporting steel pipe stand column and fire pool wall connecting structure and a construction method. The supporting steel pipe stand column and fire pool wall connecting structure comprises a foundation pit supporting steel pipe stand column, a horizontal bottom plate, a fire pool wall plate and a combined water stop steel plate piece, wherein a post-cast strip is arranged in the connecting position of the fire pool wall plate and the bottom plate, the post-cast strip comprises a bottom plate post-cast strip and a wall plate post-cast strip, the combined water stop steel plate piece comprises a vertical wall inner water stop plate and a horizontal plate inner water stop plate, the horizontal plate inner water stop plate comprises vertical edge water stop plates and a parallel edge water stop plate, both ends of the parallel edge water stop plate are integrally connected with the inner side ends of the vertical edge water stop plates on the both sides respectively, no connection exists between the foundation pit supporting steel pipe stand column and the combined water stop steel plate piece, and a gap is reserved. According to the supporting steel pipe stand column and fire pool wall connecting structure, the construction difficulty caused when the supporting steel pipe concrete stand column in a deep foundation pit conflicts with the fire pool wall and the fire pool bottom plate is solved, the structure construction is conducted smoothly, the construction progress is guaranteed, the combined water stop steel plate piece only needs to be machined in a factory, and the waterproof effect of a fire pool is guaranteed.

Description

technical field [0001] The invention relates to a connection structure of an inner wall column of a foundation pit, in particular to a connection structure and a construction method of a steel pipe column supporting a foundation pit and a fire-fighting pool. Background technique [0002] The fire-fighting pool is a pool that provides each or all of the fire-fighting water during the entire fire period after a fire breaks out in a building, and is generally set in the basement or buried underground. After the fire water tank is in operation, the fire control center immediately activates the emergency plan, the fire water pump starts to run, and the water source of the canceled waterproof pool is used to continuously replenish the water for the fire hydrant and the sprinkler system. The fire water pool stores water for fire fighting and has a large volume. The waterproof structure of the pool is the top priority of construction. When supporting the construction of the basemen...
