Embodiment 1

[0026] A method for repairing and strengthening the external thermal insulation of a compartmentalized exterior wall, comprising the following steps:

[0027] (1) On the original outer wall 1, cut out a plurality of horizontal strip-shaped areas 2 with a height of 20cm at equal intervals, cut to the base wall, remove the original insulation system, and clean it up. Interface treatment, the spacing of the transverse band zone 2 is 2.8m;

[0028] (2) Use ready-mixed mortar DPM10 to paint multiple rectangular mortar blocks 3 with a size of 10cm*10cm in the horizontal strip area 2 at equal intervals of 0.5m, and the thickness is flush with the original external wall surface;

[0029] (3) Paint light-weight thermal insulation mortar on the rest of the horizontal strip area 2, and the thickness is flush with the original external wall;

[0030] (4) Lay the fiber cloth 4 with carbon fiber glue longitudinally along the position of the rectangular mortar block 3, and sprinkle sand on ...

Embodiment 2

[0036] A method for repairing and strengthening the external thermal insulation of a compartmentalized exterior wall, comprising the following steps:

[0037] (1) On the original outer wall 1, cut out a plurality of horizontal strip-shaped areas 2 with a height of 25cm at equal intervals, cut to the base wall, remove the original insulation system, and clean it up. The horizontal strip-shaped areas 2 are painted with interface agent Interface treatment, the spacing of the transverse bands is 3m;

[0038] (2) Use ready-mixed mortar DPM15 to paint multiple rectangular mortar blocks 3 with a size of 10cm*10cm in the horizontal strip area 2 at equal intervals of 1m, and the thickness is flush with the original external wall surface;

[0039] (3) Paint light-weight thermal insulation mortar on the rest of the horizontal strip area 2, and the thickness is flush with the original external wall;

[0040] (4) Lay the fiber cloth 4 with carbon fiber glue longitudinally along the positi...

Embodiment 3

[0046] A method for repairing and strengthening the external thermal insulation of a compartmentalized exterior wall, comprising the following steps:

[0047] (1) On the original outer wall 1, cut out multiple horizontal strip-shaped areas 2 with a height of 30cm at equal intervals, cut to the base wall, remove the original insulation system, and clean it up. Interface treatment, the spacing of the transverse bands is 3.2m;

[0048] (2) Use ready-mixed mortar DPM10 to paint multiple rectangular mortar blocks 3 with a size of 10cm*10cm in the horizontal strip area 2 at equal intervals of 0.5m, and the thickness is flush with the original external wall surface;

Abstract

The invention discloses a repairing and reinforcing method for a partition type outer wall outer heat insulation system. The repairing and reinforcing method comprises the following steps that (1) a plurality of transverse band-shaped areas are cut out on an original outer wall surface at equal intervals, cutting is conducted until reaching a base layer wall body, the original heat insulation system is removed and cleaned up, and interface treatment is conducted on the band-shaped areas by painting an interface agent; (2) a plurality of rectangular mortar blocks are whitewashed out in the transverse band-shaped areas at equal intervals by using premixed mortar, and each rectangular mortar block is flush with the original outer wall surface in thickness; (3) lightweight heat insulation mortar is whitewashed in the rest areas of the transverse band-shaped areas, and the lightweight heat insulation mortar is flush with the original outer wall surface in thickness; (4) fiber cloth is laidand attached by using an adhesion agent in the longitudinal direction along the parts with the rectangular mortar blocks, and interfacial roughening is conducted by scattering sand on the surface of the adhesion agent before the adhesion agent is not fully solidified; (5) flexible crack-resistant mortar is whitewashed on the entire outer wall surface in a batched mode, and an alkali-resistant fiberglass mesh is embedded in and is reinforced by using anchor bolts; and (6) finally, a decorative finish layer is restored. The repairing and reinforcing method for the partition type outer wall outerheat insulation system is small in reconstruction area, convenient to construct, low in cost, short in period and little in influence.

Description

technical field [0001] The invention relates to the technical field of exterior wall repair, in particular to a method for repairing and reinforcing the external thermal insulation of an exterior wall with compartments. Background technique [0002] With the promotion and development of building energy conservation in my country, various external thermal insulation systems for external walls emerge in endlessly. Due to various reasons such as construction, materials, and design, many projects have various quality problems within a few years of delivery, especially cracking of external thermal insulation systems. , Leakage, shedding phenomenon is more prominent. The external thermal insulation system of the external wall of many projects has suffered from serious pulverization, and the external thermal insulation system has lost its original functionality, and it is very easy to fall off and cause safety accidents. At present, in view of this situation, the general repair met...
