Embodiment 1

[0108] see figure 1 , a kind of construction method of the fair-faced concrete finish renovation of existing building exterior wall, this construction method comprises the following steps successively:

[0109] Step 1: template processing:

[0110] (1) Cut the formwork into blocks according to the width of the exterior wall of the existing building, where the formwork adopts a steel plate with a thickness of 4mm;

[0111] (2) Use an angle grinder and an electric wire brush to grind and derust the inner surface of the formwork obliquely, and then apply a layer of universal glue or building structure adhesive evenly on the inner surface of the formwork that has been polished and derusted. A stainless steel plate with a thickness of 0.4-0.8mm is pasted on the inner surface of the painted formwork to form a clear water formwork;

[0112] (3) The outer corrugation and transverse back ribs around the clear water formwork are reinforced with equilateral angle steel supports with sp...

Abstract

The invention discloses a transformation and construction method used for facing bare concrete of an existing building outer wall. The method comprises the steps of processing of a formwork, binding of reinforcing steel bars, installation of bare formwork, casting of the bare concrete, removal of the bare formwork, maintenance of the bare concrete, cutting of visible joints, blocking and repairing of split bolt holes and coating of protective paint. According to the method, a steel formwork of which the inner surface is attached to a stainless steel board servers as the bare formwork,, reinforcing steel bar meshes serve as structural bars, the self-compaction bare concrete serves as a bare concrete mixture, and the construction of a thin-type bare concrete faced wall is finished in the mode that many times of rolling over construction are conducted from the bottom to the top of the existing building outer wall. The method not only improves the appearance quality of the bare concrete, but also ensures close integration between the newly-cast bare concrete and the existing building outer wall.

Description

technical field [0001] The invention relates to the technical field of architectural decoration, in particular to a construction method for the renovation of fair-faced concrete on exterior walls of existing buildings, and is particularly suitable for improving the appearance quality of fair-faced concrete and ensuring the tightness between freshly poured fair-faced concrete and the exterior walls of existing buildings. combined. Background technique [0002] At present, the materials commonly used for building exterior wall decoration at home and abroad include: exterior wall paint, ceramic tiles, granite, marble, glass curtain wall, aluminum curtain wall, etc. Impact, coupled with the limitation of its basic material properties and weather resistance or the influence of construction quality, the following prominent problems will appear in the service process of buildings: yellowing, cracking and peeling of paint; leakage between tile joints, surface cracking Black and fal...
