Outer heat insulating wall body for mechanically anchoring grid reinforcing rib mineral wool plate and construction process thereof

Abstract

The invention relates to an outer heat insulating wall body for anchoring a grid reinforcing rib mineral wool plate by adopting a mechanical fixing device and a construction process thereof, which is characterized in that the wall body of a basic layer is leveled to be used as a combined layer; the grid reinforcing rib mineral wool plate for heat insulation is bonded on the wall before a leveling layer is dried so as to take the action of auxiliary connection and stabilization and to guarantee the flatness of the mineral wool plate; drill holes are carried out on the surface of the plate, and the grid reinforcing rib mineral wool heat insulating plate is directly fixed on the wall body of the basic layer by adopting a plastic expansion anchor so that all load of the outer heat insulating system is fully loaded by a fixed anchor bolt and is transferred to the wall body of the basic layer structure; and the organic combination of the anchor bolt and the reinforcing rib mineral wool plate can simultaneously take the action of the auxiliary stabilization on the load of the leveling layer of the wall body of the basic layer. Thus, the outer heat insulating wall body and the construction process thereof are especially suitable for the outer heat insulating and energy saving modification project of the outer wall of a building and can preferably solve the technical difficulties of poor loading force and difficult surface treatment of the old basic layer of the outer wall.

Description

Technical field [0001] The invention relates to an external thermal insulation wall body and a construction process of a mechanical fixing device anchoring a grid-reinforced rib mineral wool board, and is especially suitable for energy-saving renovation projects of existing building external walls. Background technique [0002] The existing mechanically anchored mineral wool board external thermal insulation wall is a composite wall formed by combining the base wall and the mineral wool board. Due to the low tensile strength and flexural strength of the mineral wool board, steel wire mesh is generally used for surface reinforcement. This structure requires that when the mineral wool board is fixed, a gasket must be added between the steel wire mesh and the surface of the mineral wool board. There is a certain distance between the steel wire mesh and the mineral wool board; at the same time, use anchors to directly fix the steel wire mesh and the mineral wool board on the str...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the disadvantages of the existing mechanically anchored mineral wool board external insulation wall using anchors and steel wire mesh fixing methods that may cause hidden dangers in quality, safety and stability, the present invention provides a mineral wool board anchored with a mechanical fixing device to anchor the grid reinforcement The external thermal insulation wall and construction technology, the external thermal insulation wall can not only solve the quality and safety and stability problems that may be caused by increasing the load of the leveling layer, but also can significantly improve the tensile strength and flexural strength of the mineral wool board
