Anchorless Construction Method for Addition and Retrofit of Light Steel Structures

Abstract

The utility model relates to a non-anchor construction method for light steel structure floor adding reconstruction and aims to provide a construction method for light steel structure floor adding reconstruction without anchoring with the roof of an original house to ensure the integrity of the original roof structure. The non-anchor construction method comprises the following steps: (1) clearing the roof (1) to be smooth and clean; (2) determining the vertical projection area of a light steel structure (2) on the roof (1), and uniformly tiling an asphalt and coarse sand mixture (3) on the area; (3) placing a ground beam (4) on the asphalt and coarse sand mixture (3), and ensuring the smoothness of the ground beam (4); (4) mounting the light steel structure (2) on the ground beam (4); (5) plastering the surrounding of the ground beam (4) to realize seamless contact of the ground beam (4) and the roof (1). The light steel structure and the roof are firmly connected through the frictional resistance of the ground beam and the contact surface of the asphalt and coarse sand mixture, so that the non-anchor structure floor adding reconstruction is realized.

Description

technical field [0001] The invention relates to a non-anchor construction technology for layer-adding transformation of a light steel structure. Background technique [0002] With the continuous development of my country's economy, urban land is becoming more and more tense, and under the background of difficult land acquisition and high new construction costs, more and more houses are beginning to use light steel structures for layer-added renovations to expand the use of space. However, in the process of layer-added transformation, there are also the following problems: [0003] 1. The existing light-steel structure adding storey is reliably connected to the floor, which will inevitably destroy the integrity of the floor. If the waterproof treatment is not done properly, there will be water seepage on the floor, which will seriously affect the normal use of the house. [0004] 2. Noise, vibration, etc. will be generated during the construction process of adding floors, w...
