Gridding cloth external thermal insulation fixing system

Abstract

The invention provides a gridding cloth external thermal insulation fixing system. The system comprises a structure body, a thermal insulation block, gridding cloth, anchor rods, anchor rod gaskets and pull rod mechanisms, wherein the thermal insulation block is attached to the outer surface of the structure body, and the gridding cloth is attached to the outer surface of the thermal insulation block; each pull rod mechanism comprises a transverse adjusting base pre-embedded in the outer surface of the structure body, a pull rod, a nut installed on the screw section of the pull rod and a pressing piece; a plurality of anchor holes are regularly distributed in the gridding cloth and are divided into longitudinally extending long holes and round holes; the inner end of each pull rod is clamped into the corresponding transverse adjusting base, a limiting step and the screw section are arranged at the outer end of each pull rod, and the screw section penetrates through the long holes and is matched with the nut, the pressing piece and the limiting step to press the gridding cloth; the inner end of each anchor rod is nailed into the structure body, and the outer end of each anchor rod penetrates through the corresponding round hole and is pressed outside the gridding cloth through anchor rod gaskets. The gridding cloth external thermal insulation fixing system has the advantages that the external thermal insulation structure is more stable and not prone to falling off, the structure can be flexibly adjusted, and the gridding cloth is good in crack resistance.

Description

technical field [0001] The invention relates to the field of passive houses, in particular to a grid cloth external heat preservation and fixing system. Background technique [0002] Compared with internal insulation, external thermal insulation of buildings has the advantages of small temperature stress and good durability due to the protection of the main load-bearing structure. However, external wall insulation often falls off under the action of wind pressure. [0003] The external insulation systems commonly used in ultra-low energy buildings include graphite polystyrene board thin plastering system and rock wool thin plastering system. Due to the large thickness of external insulation required for ultra-low energy buildings, the safe connection with the wall is more important. The current fixing method is the combination of sticking and anchoring. The graphite polystyrene board thin plastering system is mainly sticky, and the rock wool system is based Anchors are the ...

Problems solved by technology

[0005] In addition, the thin plastering system now generally uses alkali-resistant glass fiber mesh cloth as anti-cracking and auxiliary fixing measures, but the alkali-resistant glass fiber has limited alkali corrosion resistance, which also affects the service life of the outer insulation surface
