Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] The technological process of construction method of the present invention is as figure 1 As shown, the method mainly includes the following steps:

[0027] Step 1: First, select a plastering and leveling area on a base layer 5 of the wall, fix a screw 6 on one side of the area, and then fix a screw 6 on the lower corner of the same side of the area, just below the above-mentioned screw 6, The distance between the screws 6 is not greater than 1m, the anchoring depth is not less than 25mm and used with plastic expansion sleeves, and arranged in a plum blossom shape;

[0028] Step 2: stretch the thread between the tops of the above two screws 6, the minimum distance between the thread and the wall should meet the design requirements of the insulation layer 3, and adjust the length of the screw 6 exposed to the base surface of the wall;

Abstract

The invention discloses a construction method and structure for preventing a building external wall heat-preservation mortar system from falling off. According to the method, by utilizing anchoring force of screw spikes (6), through alkali-resisting glass fiber gridding cloth (2), the external wall heat-preservation mortar system is connected into a whole to be fixed to an external wall of a building. Compared with a traditional building external wall heat-preservation mortar system, the construction method and structure utilize anchoring force of the screw spikes to enable the external wall heat-preservation mortar system to be connected into a whole to be fixed to the external wall of the building through the alkali-resisting glass fiber gridding cloth, so that mechanical anchoring is improved, connection of the external wall heat-preservation mortar system and a base-layer wall body is firm, and the quality accident that due to hollowing, cracking and the like of the building external wall heat-preservation mortar system, the system falls off in a large-area mode is effectively avoided.

Description

technical field [0001] The invention relates to a construction method for preventing the thermal insulation mortar system of the outer wall of a building from falling off, and the method belongs to the technical field of construction engineering. Background technique [0002] During the construction of building exterior wall insulation mortar, due to reasons such as workers or materials, the veneer layer of the insulation mortar and the anti-cracking mortar protective layer have hollowing and cracking, and rainwater will penetrate into the insulation mortar layer in large quantities. After the mortar layer absorbs water, it will obviously increase its own weight, causing quality accidents such as large-scale shedding of the external wall insulation mortar system. [0003] In view of this, how to effectively prevent large-area shedding caused by hollowing and cracking of the thermal insulation mortar system has become a technical problem to be solved urgently in the industry....
