Mounting structure for roof trusses and arc-shaped multilayer berm and construction method of berm

Abstract

The invention discloses a mounting structure for roof trusses and an arc-shaped multilayer berm and a construction method of the berm. The berm stretches across the plurality of roof trusses and is suspended on lower strings of the roof trusses, a berm unit is formed between every two adjacent roof trusses, the whole berm is formed by connecting the plurality of berm units in series, each berm unit comprises four hanging rods, the lower ends of every four hanging rods are connected through two walkway longitudinal beams and two walkway cross beams to form a parallelogram frame, and walkway plates are arranged inside the parallelogram frames. The construction method of the berm comprises the steps that the whole arc-shaped berm is divided into a plurality of hoist units and spare part unitsaccording to the distance between every two adjacent roof trusses, each spare part unit is located between the two corresponding hoist units, and then the steps of prefabricating semi-finished products in a factory, splicing the hoist units outside a span, hoisting the hoist units outside the span, and splicing the spare part units inside the span are adopted to complete the construction of the arc-shaped multi-layer berm. According to the construction method, the working efficiency is improved, and the hoisted hoist units are used as an operating platform, so that the construction cost is saved.

Description

technical field [0001] The invention belongs to the technical field of building steel structure construction, and in particular relates to an installation structure of a roof truss and an arc-shaped multi-layer horseway and a construction method of the horseway. Background technique [0002] With the increasing spiritual and cultural needs of human beings, cultural tourism complex projects centered on theme parks continue to emerge, with unique architectural shapes and unique regional characteristics, especially those represented by large-scale characteristic performance venues (gymnasiums, theaters, etc.) stand-alone building. [0003] Performance venues mostly use steel-concrete structures or steel structures as the main structure. A large number of stage machinery facilities, pipelines, controllers, lighting equipment, etc. need to be suspended above the performance venues. In order to facilitate the staff to install these equipment , Debugging and maintenance, arc-shape...

AI Technical Summary

Problems solved by technology

[0004] At present, the main method of installing the bridleway is to install the bridleway after the roof structure truss is installed, and include the installation of the bridleway in the interior decoration project of the performance hall installation. In this way, not only the installation progress is slow, but also, due to the roof capping, It is impossible to use external equipment to lift the sectioned catwalk through the gap of the roof truss. If a small crane is used to enter the venue to lift the sectioned catwalk, at this time, due to the limited hoisting capacity, there will be many high-altitude assembly operations of the catwalk and a high safety risk. Or it is necessary to set up a large number of measure brackets in the venue, which is expensive
