Construction method of composite external thermal insulation cast-in-place concrete structure and cast-in-place concrete structure
The invention provides a construction method of a composite external insulation cast-in-place concrete structure and the cast-in-place concrete structure, and belongs to the technical field of constructions.The construction method comprises the steps that a mounting formwork, an insulation board and a wood formwork are erected around steel bars, a pouring cavity is defined by the insulation board and the wood formwork, and the face, making contact with the steel bars, of the insulation board is a bonding layer; actively supplementing water, namely actively supplementing water to the bonding layer before pouring; concrete pouring is conducted, specifically, concrete is poured into the pouring cavity; water absorption of a bonding layer at the initial stage of concrete setting can be offset, so that cracks are avoided, and the maintenance cost is prevented from being increased; according to the construction method of the composite external thermal insulation cast-in-place concrete structure, the problem that in the prior art, the face, close to a thermal insulation formwork, of concrete of a thermal insulation composite integrated pouring formwork is prone to cracking is solved.
本发明提供一种复合外保温现浇混凝土结构的施工方法及现浇混凝土结构，属于建筑技术领域，包括：安装模板，保温板和木模板围绕钢筋架设，保温板和木模板围合形成浇筑腔，所述保温板与所述钢筋接触的面为粘结层；主动补水，浇筑前主动对粘接层进行补水；混凝土浇筑，向所述浇筑腔内灌注混凝土；能够抵消混凝土凝结初期粘接层的吸水，从而避免裂缝的产生，避免增加维护费用；本发明提供的复合外保温现浇混凝土结构的施工方法，解决了现有技术中的保温复合一体化浇筑模板的混凝土靠近保温模板的一面容易出现裂缝的问题。
