Abstract

The invention relates to a frame column waterproof construction method in reverse construction, which comprises the following steps: digging earth elevation, and arranging the frame column at a preset position below the foundation; arranging flexible waterproof materials on the outer surfaces of the frame columns and extending below the foundation; arranging a stainless steel annular device at the cross contact position of the frame column and the foundation; and arranging a reinforced concrete bottom plate surrounding the frame column on the upper part of the foundation. By using the method provided by the invention to carry out the waterproof construction work of the frame column, the waterproof problem in the construction process can be effectively solved, and the method can be widely applied to the technical field of constructional engineering.

Description

Waterproof construction method for frame column in reverse construction method
Technical Field
The invention relates to the technical field of constructional engineering, in particular to a waterproof construction method for a frame column.
Background
In the reverse construction, the construction work of the cast-in-place pile to replace the frame column is encountered. However, in the prior art, the waterproof work of the intersection part of the structural bottom plate and the column is a weak link of the waterproof construction of the whole structure, and the technical scheme which can well solve the waterproof purpose of the part still does not exist in the prior art, so that the quality of the construction engineering is influenced, and the operation cost in the construction process is increased.
In the prior art, the frame column of the building does not penetrate through the waterproof layer, the frame column is arranged on the pile foundation, and a waterproof structure is arranged between the frame column foundation and the pile cap. In the reverse construction, a part of the pile is used as a frame column, and the waterproof detail treatment problem exists.
Disclosure of Invention
In order to solve the technical problems, the technical scheme provided by the invention is as follows:
a frame column waterproof construction method in reverse construction comprises the following steps:
digging earth elevation, and arranging the frame column at a preset position below the foundation;
arranging flexible waterproof materials on the outer surfaces of the frame columns and extending below the foundation;
arranging a stainless steel annular device at the cross contact position of the frame column and the foundation;
and arranging a reinforced concrete bottom plate surrounding the frame column on the upper part of the foundation.
Further, the flexible waterproof material extends to the position of the contact surface between the bottom plate and the foundation.
Furthermore, a gap which is filled with flexible waterproof materials and has a regular shape is arranged at the position of the cross contact surface of the frame column and the foundation.
Furthermore, a pre-tightening system is arranged on the stainless steel annular device, so that acting force is applied to the flexible waterproof material according to different underground water levels.
Further, the stainless steel ring device is clamped inside the notch.
After the method is adopted, the invention has the following advantages:
by adopting the method to carry out the construction work of the frame column, the waterproof problem of the cross position of the frame column and the bottom plate in the prior art can be effectively solved, the waterproof quality in the building work is improved, and the construction process is simpler and the cost is lower.
Drawings
Fig. 1 is a construction schematic diagram of a frame column waterproof construction method in reverse construction.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
With reference to the attached drawing 1, the frame column waterproof construction method in the reverse construction method comprises the following steps:
digging the soil to be high, and arranging the frame column 1 at a preset position below the foundation 2;
arranging flexible waterproof material on the outer surface of the frame column 1 and extending below the foundation 2;
arranging a stainless steel annular device 3 at the cross contact position of the frame column 1 and the foundation 2;
a reinforced concrete bottom plate 4 surrounding the frame column 1 is provided on the upper portion of the foundation 2.
Wherein: the flexible waterproof material extends to the location of the interface between the soleplate 4 and the foundation 2.
The crossed contact surface position of the frame column 1 and the foundation 2 is provided with a gap 5 which is filled with flexible waterproof materials and has a regular shape.
The stainless steel annular device 3 is provided with a pre-tightening system, so that acting force is applied to the flexible waterproof material according to different underground water levels.
The stainless steel ring device 3 is clamped inside the notch 5.
The flexible waterproof material can adopt epoxy resin waterproof material or other materials.
In the process of manufacturing the frame column 1, the waterproof effect is improved by adopting the impervious concrete, and the self strength of the frame column can be improved.
In the process of laying the waterproof material, the waterproof material is extended to the position of the gap 5 between the frame column 1 and the foundation 2, so that the waterproof effect is better, and the engineering quality is improved.
