Description

Technical Field

[0001] The utility model relates to the technical field of caisson construction, in particular to a connection node between a caisson wall and a scaffold. Background Art

[0002] The shaft is usually manufactured in sections and sunk in batches. The first section is constructed only when the strength of the cutting edge reaches 100% before excavation and sinking. The remaining sections are generally prefabricated in two sections, and it is more common to sink them in one go. When prefabricating the shaft, a double row of ground scaffolding needs to be erected on the outside of the shaft wall. During construction, the outer double row of scaffolding needs to be connected and fixed to the lower structure of the shaft wall to prevent tilting or instability.

[0003] For example, in a method for erecting scaffolding for cyclone caisson construction with application number CN201911013086.0, in the prior art, a guy prop is usually used to prevent the scaffolding from tilting outward. However, the caisson method is prefabricated in two sections. When the two sections of the cylinder wall are constructed at one time, the height of the outer scaffolding is often 10m~16m. If only a guy prop is used for fixing, there is a problem of unstable fixation. Therefore, a connecting structure is required to connect the outer side of the lower section of the cylinder wall with the double-row scaffolding. How to set the connection node between the outer side of the lower section of the cylinder wall and the double-row scaffolding is the main technical problem to be solved in this application. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a connection node between a tube wall and a scaffolding which can effectively prevent the scaffolding from tilting outward and has simple construction.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A connection node between a cylinder wall and a scaffolding, wherein embedded parts are arranged at intervals on the cylinder wall, the embedded parts include embedded plates, one side of the embedded plates is provided with anchor bars, and the other side is provided with vertical connecting sleeves, the embedded plates and anchor bars are embedded in the cylinder wall, one side of the embedded plates with the connecting sleeve is flush with the outer side of the cylinder wall, and the connecting sleeve is exposed on the cylinder wall; a tie rod is also connected to the scaffolding, and the tie rod is inserted into the connecting sleeve at one end close to the cylinder wall.

[0007] Compared with the prior art, the utility model adopting the above technical solution has the following outstanding features:

[0008] The utility model discloses a kind of novel structure, and its structure is simple, convenient and economical to install and dismantle, and its structure is simple to install and dismantle, and its structure is easy ...

[0009] As a preferred embodiment, a further technical solution of the utility model is:

[0010] The tie rod includes an auxiliary connecting rod and an L-shaped plug rod. The auxiliary connecting rod is connected to the scaffolding through a connecting fastener. The vertical part of the L-shaped plug rod is inserted into the connecting sleeve, and the horizontal part is welded and fixed to the auxiliary connecting rod. The tie rod is a split structure to avoid the tie rod being too long, which may easily cause the scaffolding to collide during installation and is easy to install.

[0011] The tie rod includes an auxiliary connecting rod and an L-shaped plug rod. The auxiliary connecting rod is connected to the scaffolding through a connecting fastener. The horizontal part of the L-shaped plug rod is slidably connected to the other end of the auxiliary connecting rod, and the vertical part is inserted in the connecting sleeve.
