Description

Technical Field

[0001] This utility model relates to the field of bridge construction, and in particular to an integrated high-altitude work platform used for the construction of the crossbeam under the main tower. Background Technology

[0002] With the vigorous development of modern bridges in China, the construction scale of the crossbeams under the main tower is constantly breaking records. The construction of the crossbeams under the main tower is a high-altitude operation with high safety risks. It is necessary to set up a high-altitude work platform to facilitate construction operations and ensure the safety of high-altitude construction.

[0003] The construction of the lower crossbeam of the main tower generally adopts the cast-in-place method with steel pipe supports, and is formed in two stages. The traditional high-altitude work platform for the lower crossbeam is erected on both sides of the top of the steel pipe support using disc-lock scaffolding. It has disadvantages such as low standardization, poor high-altitude safety protection, insufficient overall structural stability, inconvenient passage, and large space occupation. It can no longer meet the requirements of standardization and high-altitude construction safety for the lower crossbeam of the main tower.

[0004] As the construction scale of the main tower's lower beam continues to break records, there is an urgent need to design a high-altitude work platform that integrates high-altitude safety protection, rebar tying platform, and access channels, and has advantages such as high standardization, stability, good high-altitude safety protection, and convenient installation and dismantling. Summary of the Invention

[0005] The purpose of this utility model is to provide an integrated high-altitude work platform that combines high-altitude safety protection, rebar tying platform, and access passage, is highly standardized, stable and reliable, and easy to install and dismantle, and is applicable to the construction of the crossbeam under the main tower.

[0006] The purpose of this utility model is achieved as follows:

[0007] An integrated aerial work platform for the construction of the lower crossbeam of a main tower is characterized by comprising vertical poles, longitudinal poles, horizontal poles, steel planks, inclined ladders, railings, perforated steel mesh, and wall attachments. A horizontal longitudinal beam is provided at the top of the steel pipe support and below the side of the lower crossbeam of the main tower. Two rows of vertical poles with the same height as the lower crossbeam are welded and installed on the longitudinal beam at the top of the steel pipe support and along the side of the lower crossbeam. Several layers of panel frames formed by longitudinal and horizontal poles are welded and installed on the vertical poles. Steel planks are laid within each panel frame as platform panels, completing the erection of each layer of platform panels. Inclined ladders are installed between the upper and lower platform panels as access routes. A layer of railings is welded and installed in the middle of adjacent panel frames as protective railings, welded to the vertical poles, and perforated steel mesh is laid between the railings.

[0008] The lower crossbeam of the main tower is cast in two stages. After the first stage of the lower crossbeam is completed, a row of attached walls is set up in the middle of the entire integrated aerial work platform along the horizontal direction. One end of the attached wall is fixed to the concrete side wall of the first stage of the lower crossbeam of the main tower, and the other end of the attached wall is welded to the vertical rod.

[0009] Furthermore, the longitudinal spacing between adjacent vertical bars is 1.4m and the transverse spacing is 3m.

[0010] Furthermore, the height spacing between adjacent upper and lower panel frames is 2.5m.

[0011] Furthermore, the distance between adjacent attached walls is 3m.

[0012] Furthermore, the vertical bars are made of I20 steel, while the longitudinal bars, horizontal bars, railings, and wall attachments are all made of ∠63*6mm angle steel.

[0013] This utility model includes vertical poles, longitudinal poles, horizontal poles, steel planks, inclined stairs, railings, perforated steel mesh, and wall attachments. It consists of two rows of vertical poles arranged side-by-side at a longitudinal spacing of 1.4m and a horizontal spacing of 3m. The bottom of the vertical poles is welded to the longitudinal beam at the top of the steel pipe support of the main tower's lower crossbeam, making the vertical poles and the steel pipe support of the main tower's lower crossbeam a single unit. The height of the vertical poles is the same as the height of the main tower's lower crossbeam. Along the vertical direction of the vertical poles, a platform panel composed of longitudinal poles, horizontal poles, and steel planks is welded and installed every 2.5m. An inclined stairs are installed between the upper and lower platform panels. The longitudinal and horizontal poles are welded to the vertical poles to form a whole. Workers can easily access every work area on the side of the main tower's lower crossbeam via each platform panel and the inclined stairs. The outer surface of the platform is equipped with perforated steel mesh and railings as high-altitude edge protection facilities, effectively ensuring the safety of high-altitude operations. The entire platform integrates high-altitude safety protection, a rebar tying platform, and access channels, exhibiting a high degree of standardization. The platform is connected to the first pouring section of the main tower's lower beam via an attached wall, ensuring its stability and reliability.

[0017] 3. Convenient access and easy construction operations. Workers can reach every work area on the side of the main tower's lower beam via the platform panel and inclined stairs, making high-altitude operations as easy as walking on flat ground;
