Embodiment Construction

[0014] In order to further understand the content and features of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0015] The first step: remove the protruding part and sundries of the concrete wall 7, and clean up the dust;

[0016] The second step: smooth the masonry wall 3 and the concrete wall 7 with anti-cracking mortar, and add the first glass fiber mesh cloth 2;

[0017] Step 3: After the mortar is dry, paste a 200mm wide exterior wall air barrier film 5 (100mm on each side) on the outside, and paste a 150mm interior wall air barrier film 4 on the inside (75mm on each side). ;

[0018] Step 4: After the air-permeable membrane 4 is firmly pasted, smooth the entire wall surface with anti-crack mortar and add the second glass fiber mesh cloth 8 .

Abstract

The invention discloses a passive ultralow-energy-consumption building masonry wall and concrete junction plugging construction method, and belongs to the technical field of passive house construction. The construction method comprises the steps of removing protruding parts and sundries of the concrete wall and cleaning dust; screeding the masonry wall and the concrete wall by using anti-crack mortar, and additionally paving first glass fiber gridding cloth; after the mortar is dried, pasting an air-isolating film on the outer side, pasting a breathable film on the inner side, uniformly gluing, and forbidding generation of hollowing; and after the breathable film is firmly pasted, screeding the whole wall surface by using anti-crack mortar and paving second glass fiber gridding cloth. Themethod has the advantages that air tightness of a room is guaranteed, mildewing and damage caused by moisture invasion are avoided, and durability is good.

Description

[0001] The invention belongs to the technical field of passive house construction, and in particular relates to a sealing construction method for the junction between a masonry wall and concrete in a passive ultra-low energy consumption house. Background technique [0002] Low-density ultra-low energy consumption residential project, the foundation adopts reinforced concrete raft foundation, the structural form is reinforced concrete shear wall frame structure, adopts passive construction technology, in order to meet the airtightness requirements of passive houses (n50=0.6 times / h) , it is necessary to seal the junction between masonry wall and concrete. Contents of the invention [0003] The purpose of the patent of the present invention is to provide a construction method for sealing the junction of masonry wall and concrete in a passive ultra-low energy consumption house, which effectively solves the problem of airtightness at the junction of masonry wall and concrete and ...
