The invention discloses a building foundation structure which comprises a foundation base and a short column. The foundation base is placed under the ground and comprises a foundation formwork and a foundation top cover. The foundation formwork comprises a foundation bottom plate and a peripheral wall plate, and the foundation bottom plate, the peripheral wall plate and the foundation top cover define a mold cavity. Concrete is poured in the mold cavity, and the shot column penetrates through the foundation top cover to be fixedly connected with the foundation formwork. The foundation formwork is formed by two or more combined members which are spliced around the periphery of the short column. Each combined member comprises a member bottom plate, a member wall plate and a member frame. The member bottom plates are spliced into the foundation bottom plate, the member wall plates are spliced into the peripheral wall plate, the combined members are connected through the member frames, and the combined members and the short column are also connected through the member frames. The combined members which can be spliced into the foundation base are used, and one single combined member is small in size, low in weight, convenient to transport and build up. Meanwhile, the invention further discloses a construction method of the building foundation structure.
Description
technical field [0001] The invention relates to the field of engineering equipment and construction schemes, in particular to a building foundation structure for steel or iron structure engineering construction, a construction method and a combined component thereof. Background technique [0002] At present, in the construction of steel structures such as towering steel masts and portal steel frames, the foundations are mostly cast-in-place reinforced concrete or prefabricated reinforced concrete foundations, both of which have obvious shortcomings. [0003] The cast-in-place reinforced concrete foundation has a long construction and maintenance cycle, and the maintenance time alone takes 28 days. During such a long construction process, the probability of encountering resistance from various aspects is relatively high, so that the project construction can be completed smoothly, and there are uncertainties. . [0004] The prefabricated reinforced concrete foundation, in add...
