Embodiment Construction

[0023] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, a multifunctional platform suitable for cable-stayed bridge construction of the present invention includes a cable-stayed bridge tower body 1, and a climbing cone is built inside the cable-stayed bridge tower body 1.

[0024] Such as Figure 5 , Figure 6 As shown, the climbing cone is composed of embedded parts 9 threaded with high-strength studs 10, high-strength studs 10 threaded with tapered sleeves 11, and tapered sleeves 11 connected with high-strength bolts 8 through threaded holes on the bottom surface. Every four climbing cones form a group, and a group of climbing cones are combined by a positioning embedded part 12 inside the tower body to form a climbing cone assembly.

[0025] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the three vertical surfaces of the tower body 1 respectively have several climbing cone assemblies on the same horizontal line. The conical bottom surf...

Abstract

A multifunctional platform suitable for construction of cables of a cable stayed bridge comprises a cable stayed bridge tower body, wherein high-strength bolts connected by embedded parts through threads are arranged in the cable stayed bridge tower body; the high-strength bolts are in threaded connection with cone-shaped sleeves; threaded holes of the cone-shaped sleeves are connected with the high-strength bolts to form crawling cones; each four crawling cones are combined through a positioning embedded part to form a crawling cone component; a plurality of crawling cone components are arranged on the same horizontal line on three vertical surfaces of the cable stayed bridge tower body; one crawling cone component is in bolted connection with a cantilever cross beam; the other end of the cantilever cross beam is connected with a sway brace; the lower end of the sway brace is connected with another pre-buried crawling cone; a plurality of cantilever cross beams are connected together with longitudinal beams to form a three-side surrounding platform of the cable stayed bridge tower body; the cantilever cross beams with scaffold boards and the longitudinal beams with guardrail devices together form the multifunctional platform; and a scaffold, large-tonnage hoisting equipment and stretching equipment are arranged on the multifunctional platform. The multifunctional platform integrates large-tonnage hoisting, large-tonnage stretching, synchronous cross construction, and safety protection for spanning an existing line, and is ideal construction equipment for cable stayed bridges.

Description

technical field [0001] The invention relates to a working platform for building construction, in particular to a multifunctional platform suitable for cable construction of cable-stayed bridges. Background technique [0002] Cable-stayed bridges play an important role in the field of bridge construction in my country, but there are some technical difficulties in the construction of cable-stayed bridges. In densely populated cities, it is often necessary to build some cable-stayed bridges, and many of these cable-stayed bridges are designed to cross existing lines (such as railways and highways). In order to alleviate the traffic pressure and keep the traffic smooth, the construction of the cable-stayed bridge can only make full use of the above-ground space of the construction site, which increases the difficulty requirements for the performance of the working platform that can carry out the safe construction and safety protection of the cable-stayed bridge; The increase in...
