Description

Technical Field

[0001] The present invention relates to the technical field of building construction, in particular to an assembled elevator foundation structure for construction in a fertilizer trough area of ​​a foundation pit. Background Art

[0002] During construction, construction elevators, as critical vertical transportation equipment, have a foundation whose stability and safety directly impact construction efficiency and safety. Traditional construction elevator foundations typically utilize poured concrete or simple steel structures. However, in specialized construction environments, such as those in foundation pits and manure troughs, this presents a problem: the soil in and around the manure troughs can experience uneven settlement due to loose backfill or complex geological conditions, leading to tilting or instability in the elevator foundation, potentially endangering the normal operation of the construction elevator and the safety of personnel.

[0003] In order to solve the above problems, the existing patent document CN219710376 U discloses an anti-settling construction elevator foundation set at the position of the fertilizer trough, including an I-beam, a first steel plate, an equilateral angle steel, a round steel U-shaped clip and an embedded part. Two ribs are fixedly connected to the outer wall of one side of the second steel plate, and the two ribs are respectively fixedly connected to the outer walls on both sides of the I-beam; multiple I-beams are arranged in parallel at equal distances. By arranging multiple I-beams at the top of the backfill soil, adjacent I-beams are fixed by welding with equilateral angle steels; embedded parts are fixedly connected at the position corresponding to the I-beam in the structural wall; a cushion layer is provided at the top of the original soil layer, and a round steel U-shaped clip is bolted to the upper surface of the cushion layer at the position corresponding to the I-beam, one end of the round steel U-shaped clip is connected to the I-beam, and the other end is fixed to the embedded part through the second steel plate; a first steel plate is provided on the lower surface of the elevator foundation body, and the first steel plate is fixedly connected to the upper surface of the I-beam. However, this technology has the following disadvantages:

[0004] First, I-beams are connected by welding angle steel, which makes the disassembly process cumbersome, time-consuming and labor-intensive. The welding parts are prone to material damage, making it difficult to reuse the steel, increasing material waste and economic costs.

[0005] Second, the structural rigidity relies on welded connections, which lack flexibility and are difficult to adapt to the complex and changing geological conditions of the fertilizer trough area, such as soft soil or uneven backfill. This leads to a high risk of uneven settlement. This settlement can generate significant internal stress in the rigidly connected foundation structure. In severe cases, it can cause cracking, tilting, or even failure, compromising the safe operation of the construction elevator. Summary of the Invention
