Description

A simply supported platform for the construction of high bridge piers

technical field

The utility model relates to a simply supported platform, in particular to a simply supported platform used for the construction of high pier columns of bridges.

Background technique

The construction platform is a temporary bridge built for engineering construction and transportation needs. Since the construction platform is a temporary construction structure, its state is constantly changing. There are a large number of construction equipment and personnel on the platform, and the load is constantly changing. The state of the existing construction platform has poor loadability, rigidity and strength. In severe cases, it may even collapse, posing a threat to personal safety.

Contents of the invention

The purpose of the utility model is to provide a simply supported platform for the construction of high pier columns of bridges with simple structure, convenient use and high safety.

In order to achieve the above object, the technical solution of the utility model is:

A simply supported platform for the construction of high bridge pier columns, comprising a pier body, a working platform, a pier cap, and a simply supported plate, the bottom of the pier body is buried in the soil, the top of the pier body is provided with a pier cap, The upper ends of both sides of the front of the body are respectively provided with working platforms horizontally, and three simply supported plates are arranged vertically in the middle of the bottom of the said working platform. The bottom of the working platform and the side of the bottom of the working platform are provided with vertical supports. The combination of pier body, working platform, simply supported plate and vertical supports is in the shape of "Tian", and the four "mouth" fonts are respectively equipped with oblique supports. The side of the vertical support and the simply supported plate is provided with connecting brackets, the upper ends of the sides of the pier body are respectively horizontally provided with horizontal support rods, the bottom of the horizontal support rods is vertically provided with support rods, and the lower ends of the described support rods are provided with The gusset plate, the inner part of the bottom of the pier body is provided with pre-components.

Further, railings are set on the top of the working platform.

Further, the gusset plate and the horizontal struts are horizontal.

Further, the working platform and the three simply supported plates forming the "earth"-shaped simply supported plates are horizontal.

The utility model is a simply supported platform used for the construction of high pier columns of bridges, and its beneficial effects are as follows:

The utility model uses simply supported boards for connection and fixation, and is composed of three simply supported boards in the shape of "earth". The torsional moment of inertia is large, the compressive capacity is increased, and the rigidity and strength are increased. At the same time, an oblique support is set in the middle of the "Tian" shape to increase the stress strength and load-bearing capacity of the slope. The railings on the working platform can protect the The personal safety of the construction personnel can avoid unnecessary accidents. The simply supported platform for the construction of high bridge piers has a simple overall structure, is convenient to use, and has high safety.
