Description

Technical Field

[0001] The utility model relates to the technical field of connecting a circular pile with an I-beam, and more specifically, to a hoop-type fixing device for installing an I-beam on the top of a circular pile. Background Art

[0002] In foundation projects under rocky geological conditions such as elevated roads and bridges, circular piles are often used for pile foundation construction. A distribution beam needs to be set up on the top of the circular pile. The distribution beam generally uses an I-beam. In order to ensure the stability of the I-beam on the circular pile, the connection between the circular pile and the I-beam is generally achieved by welding. Sometimes, a groove matching the shape of the I-beam is opened on the top of the circular pile to increase the contact area between the circular pile and the I-beam and improve the connection stability. When the I-beam and the circular pile need to be disassembled and put into circulation again, the force performance of the I-beam will be affected and the service life of the I-beam will be shortened; the top of the circular pile also needs to be polished and cleaned, and even the slot size needs to be adjusted, which increases the process and causes waste of circular pile materials. Therefore, the welding and slotting process will make the connection and splitting construction efficiency of the I-beam and the circular pile low, shorten the service life of the I-beam, and cause waste of circular pile materials.

[0003] A Chinese patent (publication number CN208899470U) discloses a flange connection structure between the top of a steel pipe pile and an I-beam beam, which includes the following contents: a fixed flange is welded on the top of the steel pipe pile, the I-beam beam is placed horizontally on the fixed flange, and a limit flange is installed on both sides of the I-beam beam on the fixed flange. Each limit flange is an arc-shaped flange plate, and two vertically arranged limit plates are welded on the limit flange. The bottom edge of the limit plate presses the lower flange plate of the I-beam beam, and the side edge of the limit plate presses against the web of the I-beam beam to fix the I-beam beam on the top of the steel pipe pile.

[0004] The above patent connects the circular steel pipe piles and I-beams through a flange structure, which is easy to disassemble and assemble, reduces the damage to the steel pipe piles and I-beams, increases the reuse rate of the steel pipe piles and I-beams, and improves the economic benefits. However, in the above patent, the steel pipe piles and the fixed flanges are welded. If the steel pipe piles need to be separated separately for other uses, the stress performance of the steel pipe piles will also be affected to a certain extent. Moreover, the above patent is only applicable to steel circular piles. For non-metallic circular piles that cannot be welded to the fixed flange, the structure of the above patent cannot be used to connect them to the I-beam. Therefore, there is still room for improvement in the above patent. It is necessary to study a circular pile top mounted I-beam distribution beam structure that does not require welding.
