Fabricated building energy-saving thermal insulation wall and manufacturing and assembling method thereof

Abstract

The invention belongs to the technical field of building assembly, and discloses a fabricated building energy-saving thermal insulation wall and a manufacturing and assembling method thereof. The fabricated building energy-saving thermal insulation wall is sequentially provided with an internal UHPC layer, a reinforced steel bar net rack and an external UHPC layer from inside to outside; the internal UHPC layer and the external UHPC layer are mounted; the reinforced steel bar net rack is laid between the internal UHPC layer and the external UHPC layer, the reinforced steel bar net rack is filled with a sealing bonding curing agent, and curing molding is carried out to obtain the prefabricated building energy-saving thermal insulation wall; a dovetail groove structure is arranged at the outer side surface of the thermal insulation wall; and a foaming agent is sprayed to complete thermal insulation wall assembly. According to the fabricated building energy-saving thermal insulation walland the manufacturing and assembling method thereof, the internal UHPC layer and the external UHPC layer are both subjected to high-temperature calcination, have good activity and show excellent plasticity and cohesiveness after encountering water; and due to the design of the dovetail groove structure, the thermal insulation wall can be more conveniently and firmly fixed to the outer wall body ofa building, the falling risk is reduced, the product strength is improved, and the labor intensity is reduced.

Description

technical field

[0001] The invention belongs to the technical field of building assembly, and in particular relates to a prefabricated building energy-saving and thermal insulation wall and a manufacturing and assembling method thereof. Background technique

[0002] At present: the prefabricated wall adopts the principle of cast-in-place shear wall, uses galvanized light steel keel as the supporting frame, and high-strength glass magnesium plate as the non-demolition panel, and pours environmentally friendly, flame-retardant lightweight slurry inside the glass magnesium plate The final formed wall. In the final stage of the construction process of the prefabricated wall, it is necessary to smooth the mortar on the outer surface of the prefabricated or cast-in-place foundation wall to form a mortar layer, and then apply an adhesive layer on the mortar layer to attach the wallpaper Floor. However, for the existing wall structure, when arranging the wiring, it is necessary to...

Examples

Embodiment 1

[0089] Limestone and clay are mixed, calcined at high temperature, and the blocky material is ground, and gypsum powder is added to the grinding to obtain mixture A, and the inner UHPC layer is prepared by using mixture A, silica fume, fine sand, quartz powder, and water reducer; Limestone, silica, alumina, and iron oxide are mixed according to the preset mass parts to prepare the external UHPC layer; a reinforced steel grid frame is laid between the prepared internal UHPC layer and the external UHPC layer, and the reinforced steel grid frame The interior is filled with sealing and bonding curing agent, which is cured and formed in a clamped state to obtain an energy-saving and thermal insulation wall of a prefabricated building;

Embodiment 2

[0091] Carry out the mensuration of inner UHPC layer and outer UHPC layer performance, the result is as shown in table 1:
