Description

A safe operation platform for piers

technical field

The utility model relates to a construction safety operation platform, in particular to a safety operation platform for piers.

Background technique

In recent years, with the continuous development of bridge engineering, the construction technology of cap beams has become more mature and diversified. The construction of cap beams using the traditional hoop method has been favored by construction parties because of its advantages of light structure, no need for a large number of supports, simplicity compared with other construction methods, strong adaptability, and short construction period. When using the hoop method to construct the cap beam, it is necessary to first install the hoop on the pier column. The hoop is usually set at the position lower than the top of the pier column, higher than the ground, and suspended in the air. In order to allow workers to install the hoop safely, it is necessary to build a scaffold around the pier column or hoist a construction ladder so that the workers can stand on the scaffold or ladder to install the hoop. Both of these two construction operation platforms have the problems of large material consumption and low construction efficiency, and once they encounter dangerous places such as rivers, deep ditches, soft soil and silt under the bridge, it is often necessary to deal with the foundation, the construction cost is high and there is a safety hazard. Hidden danger.

Contents of the invention

The utility model provides a safe operation platform for piers to solve the technical problems in the known technology. The platform is safe and stable, has less material consumption and high construction efficiency.

The technical solution adopted by the utility model to solve the technical problems in the known technology is: a safe operation platform for pier columns, which is characterized in that it includes a support structure supported by the top of the pier column, and Two hanging baskets arranged symmetrically are fixed at both ends, and the two hanging baskets are connected by two tie rods. The left and right sides of the pier column are respectively set according to the connecting rod.

There are reserved steel bars on the top of the pier column, and the support structure adopts an axisymmetric structure, including two support beams and two pole beams. The two support beams are placed symmetrically on the top of the pier column and pass through the reserved steel bars The two shoulder pole beams are vertically fixed to the two ends of the two support beams symmetrically front and back.

Each of the hanging baskets includes two main booms and two auxiliary booms vertically fixed to the shoulder beam, the upper end of the main boom is fixed to one end of the shoulder beam, and the auxiliary boom The upper end of the upper end of the platform is fixedly connected with the shoulder pole beam, the lower end of the main boom and the auxiliary boom is fixedly connected with a platform bottom frame, and a platform pedal is fixedly connected on the bottom frame of the platform. A protective railing is fixedly connected between the auxiliary suspender and between the two main suspenders, and a protective net is hung on the outside of the main suspender and the auxiliary suspender.

A stiffening plate is provided at the connection between the shoulder pole beam and the main suspender and the connection between the main suspender and the platform bottom frame.

The utility model has the advantages and positive effects that: the supporting structure is hung on the existing piers, and the bearing capacity is reliable. The hanging baskets on the left and right sides of the pier column, the upper part is connected by a pole beam, and the lower part is connected by a tie rod, which has strong integrity, high safety factor and good stability. At the same time, the utility model has the characteristics of simple structure, high construction efficiency, repeated use, low cost and convenient use.
