Floor mold type composite bottom board structure

Abstract

The invention discloses a floor mold type composite bottom board structure which comprises a foundation (3), a slot is formed on the foundation (3) and chiseled to form a floor mold (2), steel bars are arranged in and on the slot of the floor mold (2), and concrete is poured to form a concrete rib board structure (1). The floor mold type composite bottom board structure utilizes the foundation to produce the floor mold (2), thereby being capable of adopting the simple construction method and concrete material with the amount lower than the ordinary concrete structure to construct the multi-ribbed board composite structure with the bearing force higher than the ordinary concrete structure by a plurality of times; the self-gravity and the side resistance of the floor mold (2) and the foundation (3) are utilized to offset or mostly offset underground water uplift pressure loads, thereby achieving the purposes of greatly saving using amount of steel, saving the using amount of steel by 50-80 percent, shortening the construction period by 30-50 percent and overcoming the shortcomings in the prior art.

Description

technical field [0001] The invention relates to a floor structure, in particular to a ground-mode composite base structure or a ground-mode composite raft foundation structure. Background technique [0002] With the progress of the society and the continuous development of the economy, the land used for urban construction in my country is becoming less and less, the basement is used to meet the requirements of parking and civil air defense, and the construction scale is getting larger and larger. Explosive special load or as a foundation structure to withstand very large loads such as foundation reaction. Generally speaking, the ordinary concrete structure requires a large amount of concrete, a large amount of steel bars, a high overall cost, and a long construction period. In addition, in Shanghai, Tianjin and other soft soil areas, traditional pile foundations and raft foundations are usually used to meet the requirements of foundation bearing capacity, and the engineering...

Problems solved by technology

Generally speaking, the ordinary concrete structure has a large amount of concrete, a large amount of steel bars, a high comprehensive cost, and a long construction period.

In addition, in Shanghai, Tianjin and other soft soil areas, in order to meet the requirements of foundation bearing capacity, traditional pile foundations and raft foundations are usually used, and the engineering cost is very expensive.
