Modular fabricated concrete self-insulation wallboard

Abstract

The invention discloses a modular fabricated concrete self-insulation wallboard which comprises a main wall body layer, an insulation core layer and an outer blade protection layer. The main wall bodylayer and the outer blade protection layer are connected through V-shaped steel tie bars. The V-shaped steel tie bars are composed of main wall body horizontal bars, main wall body longitudinal barsand main wall body truss steel bars. The multiple main wall body horizontal bars and the main wall body longitudinal bars penetrate into ring hook points of the main wall body truss steel bars and arewelded with the main wall body truss steel bars to form the V-shaped steel tie bars. The outer blade protection layer is filled with a polyurethane insulation material. According to the wallboard, coordination integrality between the body layer and an outer blade board is improved through the V-shaped steel tie bars; through horse tooth joint structures on the two sides of vertical seams, the anti-shear capacity of seams is improved, and the anti-seismic property is improved; and the insulation layer is closely bonded to the body layer and the outer blade layer through online foaming, and integration of insulation and the structure is achieved.

Description

Technical field: [0001] The invention relates to the field of building wallboards, in particular to a modular assembly type concrete self-insulation wallboard. Background technique: [0002] At present, the prefabricated wall panels have been more widely used, but there are the following problems: the assembly efficiency is low, and the external insulation needs to be installed after the main component is installed, and the secondary thermal insulation operation method of pasting EPS, XPS and other thermal insulation materials on the outside of the component is required. , this method increases the cost of secondary construction, and at present, the external insulation is easy to fall off, and accidents of peeling off vehicles and people are often reported, which will also cause fire hazards during the construction process; at present, the self-insulation of prefabricated wall panels mainly includes sandwich cores For thermal insulation, the main layer and the outer leaf pro...

Problems solved by technology

[0002] At present, the prefabricated wall panels have been more widely used, but there are the following problems: the assembly efficiency is low, and the external insulation needs to be installed after the main component is installed, and the secondary thermal insulation operation method of pasting EPS, XPS and other thermal insulation materials on the outside of the component is required. , this method increases the cost of secondary construction, and at present, the external insulation is easy to fall off, and accidents of peeling off vehicles and people are often reported, which will also cause fire hazards during the construction process; at present, the self-insulation of prefabricated wall panels mainly includes sandwich cores Insulation, the main layer and the outer leaf protection layer are only connected by bolts, the overall coordination is relatively weak, resulting in the inability of the outer leaf plate to bear the load, which becomes the external load of the main layer

Moreover, the production process of this product is produced by a flat die vibrating table. Most of the steel mesh cages still need to be bound manually, which has low precision and low production efficiency. It must be reversed twice to form, and the production cost is difficult to reduce;

[0003] The existing prefabricated buildings mainly have grouting sleeve self-pressing grouting technology and uncontrollable construction process, cumbersome process and high price. Due to the uncontrollable quality of grouting sleeve connection, important parts need to be poured on site to ensure the reinforcement of edge components Up and down through, the overall connection is reliable, resulting in mixed construction of prefabricated assembly components and cast-in-place components, repeated labor and increased engineering materials, resulting in an increase in cost
