Safety protection platform for pier body construction

Abstract

The pier body construction safety protection platform comprises a supporting frame formed by stacking a plurality of layers of standard units, each layer of standard unit comprises a plurality of aisle layers and supporting rods perpendicularly connected with the aisle layers in a crossed mode, every two adjacent layers of standard units are connected through a connecting plate, a plurality of mounting holes are formed in the connecting plates, and the mounting holes are communicated with the aisle layers. Bolts penetrate through the connecting plates of the two standard units of the adjacent layers to connect the two standard units of the adjacent layers, and the standard unit located at the bottom and foundation bolts pre-buried in the concrete base mold are stably installed. The supporting frame is formed by stacking and fixing a plurality of layers of standard units, each standard unit is of an integral structure prefabricated in advance, when the supporting frame needs to be used, the standard units only need to be stacked and installed layer by layer in a hoisting mode, an integral pier body construction safety protection platform can be formed, the installation time and labor cost are saved, disassembly and assembly are convenient, and the construction efficiency is improved. And recycling is facilitated.

Description

[0001] This application is a divisional application of the patent application "safety protection platform for pier body construction". The application date of the original application is June 28, 2017, the application number is 2017105122812, and the publication number is CN107119576A. technical field [0002] The invention relates to the field of bridge construction engineering, in particular to a pier body construction safety protection platform.

Problems solved by technology

[0003] In the construction of bridge pier bodies, steel pipe supports are often used to build safety protection platforms for pier body construction. Common safety protection platforms mainly include lantern frames, light climbing frames, cantilever formwork, scaffolding steel pipe safety channels, etc. Lantern frame safety protection platforms are mainly welded and reinforced. It is built by tying. After the construction of the pier body is completed, the structural components need to be dismantled. Especially when the frame formwork is removed, workers need to manually dismantle it, and it needs to be dismantled under the formwork. The safety guarantee for workers is poor; light-duty Although the climbing frame is easy to dismantle and relatively high in safety, its cost is high and it is not suitable for widespread implementation and use; while the structure of the cantilever formwork is basically the same as that of the light climbing frame, but after the structure binding is completed, it needs to be carried out with a hanging tower. Lifting, the safety during the lifting process cannot be guaranteed; the safety protection frame built by scaffolding steel pipes is often used on piers with a height below 20m, and the safety protection platform formed by the protection frame requires more labor and the amount of components Many, the erection process is slow, the erection is not standard, the pier body needs to be completely dismantled after the construction is completed, and the recycling of the safety protection platform cannot be realized
