The method of installing the steel truss and curtain wall of the daylighting roof in the air

Abstract

The invention relates to a method for installing a daylighting roof steel truss and a curtain wall in the air. The installed daylighting roof steel truss comprises a plurality of unit steel trusses, and every unit steel truss comprises a lower chord, an upper chord, a cross rod and a web member. The method comprises a first step of lifting the daylighting roof steel truss and hanging a safety net; a second step of utilizing the steel truss lower chords to serve as a supporting structure to erect a safety walkway and a construction operation platform; a third step of performing the first step and the second step in a line production mode; a fourth step of arranging double safety ropes or guardrails at the position of the safety walkway close to the edge, and installing the safety net; a fifth step of laying skirting boards on two sides of the safety walkway; a sixth step of installing a curtain wall glass frame; a seventh step of installing curtain wall glass; an eighth step of installing a drainage channel between the unit steel trusses where the curtain wall glass is installed well, enabling the drainage channel to have a certain gradient, arranging a water collecting tank at the tail end of the drainage channel, and enabling the water collecting tank to be communicated with a building drainage pipe.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and relates to a method for installing a truss and a curtain wall on the roof of a building, in particular to a method for installing a daylighting roof steel truss and a curtain wall in the air. Background technique [0002] When the skylight of the designed building is higher than the ground and the skylight is volleyed, the construction of the skylight is a difficult problem; for example, a building has no floors from the 11th floor to the 22nd floor, half of the building The area is empty, the skylight is built on the top of the 22nd floor, and the height of the skylight from the 11th floor is 50m. [0003] Two construction methods are provided in the prior art: [0004] 1. Set up full house scaffolding as a vertical operation platform, and install the steel truss and curtain wall on the platform; [0005] 2. The traditional column-type tire frame support is used to support the er...

Problems solved by technology

[0007] 1. It needs to consume a lot of turnover materials;

[0008] 2. It requires a lot of labor;

[0009] 3. After the temporary structure is erected, after the roof structure is installed, these temporary structures must be dismantled, which requires a lot of labor;

[0010] 4. All the above factors will lead to an increase in construction costs (taking scaffolding as an example, the cost of erection and dismantling is at least 25 yuan / m 3 ), the construction progress is delayed;
