Embodiment Construction
[0015] Such as figure 1 As shown, the outer steel ladder of the concrete silo of the present invention is installed in place with the slipform construction and the construction method comprises the following construction steps:
[0016] a. Leave an upper mouth on the slipform operating platform of the concrete silo, and fix the upper end of the prepared tool-type drawing steel ladder 2 on the slipform enclosure;
[0017] b. Then hook the lower end of the tool-type pull steel ladder 2 to the upper cap 3 of the engineering steel ladder 1;
[0018] c. When the sliding formwork operating platform slides up to the set height during the construction of the concrete silo, (take back the tool-type pull-out steel ladder movable ladder,) weld the engineering steel ladder 1 on the outer wall of the silo;
[0019] d. Repeat steps b to c above until the construction is completed.

The invention discloses a once mounting, locating and constructing method for a steel ladder outside a concrete silo following sliding mould construction. A construction process comprises the following steps of: leaving an upper inlet on a sliding mould operating platform of the concrete silo and fixing an upper end of a prepared tool type pulling steel ladder on a sliding mould enclosed ring; after sliding the sliding mould operating platform to a preset height during a concrete silo construction process, welding an engineering steel ladder on an outer wall of the concrete silo; and then hanging and welding the tool type pulling steel ladder on the engineering steel ladder; and repeating the steps till completely constructing. According to the method provided by the invention, rental feeof materials about ** Yuan can be saved, the cost of purchasing a safety net foot plank about ** Yuan can be saved, the cost of assembling and disassembling a riding track tower about ** Yuan can be saved, the cost of materials about ** Yuan can be saved, the cost of disassembling a needed machine matched with a tower crane or truck crane about ** Yuan per day can be saved, and the cost of a mounting machine of the steel ladder about ** Yuan can be saved. Totally, the cost about ** Yuan can be saved, a construction period can be reduced by two days, and the method is practical and economical as well as safe and has remarkable composite economic benefits.
Description
technical field [0001] The invention relates to a construction method for installing an external steel ladder on a concrete silo in a civil engineering building. Background technique [0002] The installation of the external climbing ladder of the concrete silo is a common construction project in industrial buildings. During the construction, in order to facilitate the construction personnel to go up and down, the current construction process is to build a temporary special passageway along the outer wall of the silo. The main body of the concrete silo is constructed first, and when the silo After the main body of the silo is constructed to a certain height, a temporary runway frame is erected outside the main body of the silo. The frame increases with the increase of the construction height of the silo. The frame body of the human runway is installed with a permanent steel ladder. Taking the concrete silo construction of the raw material warehouse as an example, it is nece...
