Description

The root-type column structure of the basement structure and its assembly method

This invention is aimed at optimizing the column structure of the basement structure. The space of the basement structure is mainly used for parking. While ensuring the safety of the overall structure, it improves the quality of the project and reduces the construction interface, thereby reducing the construction cost and shortening the construction period, and converting the parking space into maximize.

Generally, basements are often set up as parking space planning. Considering various construction conditions and cost, equal parking spaces are often designed. Usually, each span (one span between two columns) can provide Three large parking spaces are the top priority. Secondly, the design dimensions of the columns are planned according to the structural system on the ground, which serves as the final basis for the width of each span in the basement.

For the surface treatment of parking lot columns, generally the finished surface will be painted with surface smoothing. If the column is a concrete structure poured on site using traditional formwork, the surface of the column must be painted with mud and then painted with soil before it can be completed. noodle. However, if the column is formed by pouring concrete using traditional formwork, it will be necessary to construct a construction frame, bundle steel bars, and assemble the formwork on site. Not only will the work hours increase, but the risks to the on-site construction workers will also increase, and the surface will need to be painted with mud, which will also increase the width of the column by at least 5 to 6 centimeters.

The above problems are the complexity and shortcomings of basement structure columns that the inventor has personally experienced. The inventor has been paying attention to the above problems for a long time. Therefore, after continuous research and improvement, the present invention is finally produced. In order to ensure that Under the premise of permanent use safety, the column structure of the basement structure is optimized to reduce on-site labor, reduce construction interfaces, and ensure the width of the parking space to replace the conventional technology.

In order to improve the shortcomings of the conventional technology described in the previous paragraph, the present invention performs structural optimization on the columns of the basement structure to maximize the parking space while ensuring the safety of the overall structure.

The present invention is a root-type column structure of a basement structure and its assembly method. If the reverse construction method (including the first-floor construction method) is adopted, the first-insertion construction method of the present invention is adopted, that is, the underground soil is opened. Before excavation, the steel cage and the uprooted column structure are installed first, and concrete is poured to make the steel cage form a supporting pile structure, so that the uprooted column structure and the supporting pile structure form an uprooted column pile structure. body to replace the traditional on-site structural columns tied with steel bars and formwork grouting, which is the so-called first-in-place construction method of the present invention.

The invention can reduce the working interface, shorten the construction period and ensure the structure The quality and overall structural safety can also be a good countermeasure to improve the current shortage of work and materials and high prices.
