Problems solved by technology

Due to the lack of compactness of the sand during use, there is an inelastic space in the steel sand dumping drum. It is necessary to preload and adjust the sand drum and the overall preloading of the bracket. In addition, the sand drum is placed outdoors for a long time, and the sand is easily affected by moisture absorption and hardening. The unloading effect, there is also the situation that the top surface of the sand is uneven during the unloading sand drum, which causes structural instability and stress concentration of the upper component

Abstract

The invention relates to a support disassembling device of a steel pipe pile and relates to the technical field of bridge construction. The device comprises the steel pipe pile. The device is characterized in that a steel beam clamp is arranged on the steel pipe pile, a post cap segment is arranged on the steel beam clamp, and a disassembling stroke space is reserved between the post cap segment and the steel beam clamp. According to the support disassembling device, the principle of no-support construction of the steel beam clamp is used, the supporting post cap segment is arranged on the steel beam clamp, support construction is conducted, and the device is applied to support disassembling of the steel pipe pile.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a steel pipe pile bracket unloading device. Background technique [0002] Prior Art With the rapid development of engineering construction, there are more and more bridge projects. In bridge engineering construction, the construction method of cast-in-place beam composite support is commonly used, that is, the scaffolding method in which steel pipe pile pillars are combined with other structures. The unloading device often adopts a steel unloading sand drum. Due to the lack of compactness of the sand during use, there is an inelastic space in the steel sand dumping drum. It is necessary to preload and adjust the sand drum and the overall preloading of the bracket. In addition, the sand drum is placed outdoors for a long time, and the sand is easily affected by moisture absorption and hardening. The unloading effect, there is also the situation that the sand top surfa...
