Assembly building method for energy-saving reconstruction of existing building

Abstract

A prefabricated construction method for energy-saving renovation of existing buildings, which includes: A) adding a steel structure connecting plate on the top of the original building structure; There are building structure connections; set up energy-saving composite exterior wall panels, partition panels, laminated floor panels with foamed cement materials, and energy-saving composite roof panels with foamed cement materials, and assemble them on-site through plate connectors or directly with the jointed steel structure Connect, and fill the gap between the inside and outside of the board and between the board and the original building structure with insulation and sealing materials, that is, the energy saving of the original building and the renovation of the old building are completed; B) Adding a wall outside the original building structure Board connection board and exterior wall panel support; install energy-saving composite exterior wall panels with foamed cement materials on the outside of the original building exterior walls, and connect and fix them through the wall panel support and wall panel connectors; and fill the interior of the exterior wall panels with insulation , Sealing materials, that is, the energy-saving renovation of the exterior walls of the original buildings has been completed.

Description

technical field [0001] The invention belongs to the field of construction, in particular to an assembled construction method for energy-saving renovation of existing buildings. Background technique [0002] The development of modern cities is changing with each passing day, and new buildings emerge in an endless stream. However, at the same time, some old buildings in the city are inconsistent with the new urban appearance in many aspects. Old buildings are generally built for a relatively long time, and there is a considerable gap compared with the current requirements in terms of architectural form and architectural style. And most of them are located in the prime location of the city, and the surrounding supporting facilities are relatively complete. With the changes in urban planning, housing prices in these areas have skyrocketed. Therefore, it is not an exaggeration to describe the location of these old buildings with every inch of land. In addition, these old build...
