Problems solved by technology

[0005] However, the existing bridge pier hoop construction only relies on the static friction generated by the thick rubber clamped between the hoop and the column and the strength of the bolts used to fasten the hoop. Therefore, accurate calculations are required during construction, and the required high-strength bolt torque The coefficient μ1 often needs to be set above 0.15 to ensure safety, and it is necessary to strictly control the weight of the bridge pier cover beam formwork and pouring workers. In many cases, construction must be alternated, which affects the construction period
[0006] Therefore, the biggest defect of the existing bridge pier hoop construction method is that it relies too much on the friction of the hoop, resulting in insufficient load-bearing capacity. The present invention proposes a double hoop that enhances the horizontal pressure of the hoop to the pier to achieve anti-skid. hoop support structure

Abstract

The assembled capping beam construction safety protection integrated platform comprises a construction platform body, a guardrail is arranged on the top face of the construction platform body, and longitudinal channel steel and transverse channel steel are arranged on the bottom face. The transverse channel steel is fixedly connected with first telescopic rods through vertical positioning steel bars, each first telescopic rod comprises a groove-shaped rod section and a flat rod section, and the four first telescopic rods form a rectangular telescopic frame body through fastening bolts; secondtelescopic rods are riveted to the bottom faces of the first telescopic rods through first telescopic supporting arms, and the four second telescopic rods form a rectangular telescopic frame through fastening bolts. The first telescopic rod is riveted with a first hoop through a second telescopic supporting arm, and the second telescopic rod is riveted with a second hoop through a third telescopicsupporting arm. The double-hoop supporting structure is constructed, the concept of traditional hoop method capping beam construction is overturned, platform bearing is converted into transverse external pressure on the hoops, the static friction force between the hoops and the pier is greatly improved, the bearing capacity and safety of the platform are improved, and the platform is suitable forcapping beam construction of high piers.

Description

Technical field [0001] The invention relates to the technical field of bridge construction, in particular to a prefabricated cover beam construction safety protection integrated platform. Background technique [0002] In recent years, with the country's substantial increase in the number of railway and highway projects, bridge construction has spread to various mountainous areas with complex terrain. For example, the Sichuan-Tibet Railway and Qinghai-Tibet Highway require the construction of a large number of bridges. [0003] In mountainous areas with complex terrain, the piers of the bridge are often very high, such as the Hezhang Bridge, known as the "highest pier in Asia". It is located in Hezhang, Guizhou Province, on the Bijie-Weining Expressway, and the site is located in Yungui In the northern part of the Umong Mountains of the plateau, the terrain here is uneven, high in the west and low in the east. The Hezhang Bridge is at the highest point at this altitude, and its high...
