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

A construction method for the renovation of fair-faced concrete facings on existing building exterior walls, including formwork processing, steel bar binding, fair-faced formwork installation, fair-faced concrete pouring, clear-water formwork removal, fair-faced concrete curing, open joint cutting, and installation of pull bolt holes Sealing and trimming, protective paint coating, the construction method uses the steel formwork with stainless steel plates on the inner surface as the clear-water formwork, the steel mesh as the structural reinforcement, and the self-compacting clear-water concrete as the clear-water concrete mixture. The construction of the thin-layer clear-faced concrete facing wall is completed in the way of repeated molding construction from the bottom of the building exterior wall to its top section. The invention not only improves the appearance quality of the fair-faced concrete, but also ensures the close combination of the freshly poured fair-faced concrete and the exterior wall of the existing building.

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...
