Embodiment 1
[0045] Example 1, such as Figure 1-4As shown, an atrium rod steel staircase system includes a steel staircase 1 and a staircase tension rod 2. The two ends of the steel staircase 1 are connected with the embedded parts of the staircase in the concrete structural beam through bolts, and the uppermost steel staircase 1 is located above the steel staircase. There is an atrium top truss 3, the upper part of the stair rod 2 is connected to the atrium top truss 3 by bolts, the lower part is connected to the embedded part of the rod on the foundation floor by bolts or welded, and the stair rod 2 is welded to the corresponding part of the steel staircase 1. The steel staircase adopts the production scheme of "overall lofting, segmental sampling, and segmental welding". The overall installation process: positioning control line → temporary support erection → stair section installation → steel cable installation → temporary support removal. Stair tie rod 2 needs to be stretched, and t...

The invention discloses an atrium draw-bar steel ladder system and a construction method thereof, and aims to solve the problems that an atrium draw-bar steel ladder system in the prior art is low inconstruction efficiency and is not good in anti-seismic effect. The atrium draw-bar steel ladder system comprises a steel ladder and a ladder draw bar, wherein the two ends of the steel ladder are connected to ladder pre-embedded parts in a concrete structural beam; an atrium top truss is arranged above the steel ladder positioned at the uppermost layer; the upper part of the ladder draw bar is connected to the atrium top truss, and the lower part of the ladder draw bar is connected to the draw bar pre-embedded parts on a base bottom plate; and the ladder draw bar is fixedly connected to the corresponding portion of the steel ladder. According to the atrium draw-bar steel ladder system disclosed by the invention, the atrium truss, the draw bar and the steel ladder are combined, so that space is saved, energy conservation and environment protection are achieved, anti-seismic property is relatively good, construction efficiency is greatly improved, and outstanding advantage is achieved in aspect of economical efficiency, and therefore, the atrium draw-bar steel ladder system is an innovative new building design.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to an atrium pull rod steel staircase system and a construction method thereof. Background technique [0002] The atrium has a wide range of applications in public buildings, and is an important operation object in space combination, functional organization, and form composition, and has always been valued by architects. Its greenhouse effect and chimney effect play an important role in building ventilation and lighting, adjusting indoor temperature, and saving energy. However, existing atrium staircase systems either adopt concrete pouring or steel staircases. As one of the applications of steel structure engineering, steel stairs are structures that are connected by welds, bolts or rivets between components or parts, and are suitable for building large-span, super-high and super-heavy buildings. However, these steel stairs take up a lot of space, the seismic resist...
