Embodiment 1

[0047] Embodiment one sees Figure 1-2 As shown in , 4, the prefabricated thin thermal insulation composite exterior wall is arranged on the outside of the upper and lower two-story structural beams. The joint is located on the outside of the structural beam, and the sandwich composite wallboard should include panel 1, insulation layer 2, steel wire mesh 3, concrete 4 and wallboard tensile flexible connector 5;

[0048] The heat insulation layer 2 is a vacuum heat insulation core board, and the vacuum heat insulation core board is disconnected at least one place inside the sandwich composite wallboard and is discontinuously arranged; in this example, the discontinuously arranged area 6 is arranged in the middle of the sandwich composite wallboard upper end and lower end. This arrangement locally limits the relative sliding of the concrete layers. The discontinuous setting area 6 is set at the upper end and the lower end of the sandwich composite wallboard, that is, the part ...

Embodiment 2

[0067] Embodiment two see image 3 As shown, the difference from the first embodiment is that the non-continuous setting area 6 is set in the middle of the sandwich composite wall panels, and door and window openings 18 are set between the upper and lower adjacent sandwich composite wall panels.

[0068] Construction method step of the present invention is as follows:

[0069] Step 1. Prefabricate the prefabricated thin thermal insulation composite exterior wall in the factory, pre-embed the groove type embedded parts 12 in the wall, and at the same time fix the first connecting angle steel 14 and the prefabricated thin thermal insulation composite exterior wall through the pre-embedded supporting bolts 13;

[0070] Step 2. If the horizontal structural member 10 is a concrete member, the second connecting bolt 17 needs to be pre-embedded in the designated position of the horizontal structural member 10 during pouring or factory prefabrication. After the concrete of the horizon...

Abstract

The invention provides a novel prefabricated thin type heat preservation composite outer wall and a structural system and construction method thereof.The novel prefabricated thin type heat preservation composite outer wall comprises a panel, a heat preservation layer, steel wire mesh pieces, novel self-compacting concrete and a novel wallboard tensile flexible connector; one or more positions, in a sandwich composite wallboard, of the heat preservation layer are broken and arranged in a discontinuous mode; the novel self-compacting concrete is poured into a cavity formed between the panel and the heat preservation layer and wraps the steel wire mesh pieces on the two sides respectively; meanwhile, the concrete is integrally poured at the discontinuous arrangement areas.The position between the corresponding discontinuous arrangement area and a horizontal structural component of the heat preservation layer is filled with a supplementary heat preservation material to prevent a hot and cold bridge.The outer wall is conducted and assembled with the horizontal structural component through a connection assembly.The novel prefabricated thin type heat preservation composite outer wall is light and thin in wallboard, easy to transport and install, does not need a keel and is directly assembled to the horizontal structural component, cost brought by the keel is lowered, the construction procedure is simplified, and the novel prefabricated thin type heat preservation composite outer wall can be widely applied to civil concrete and steel structure buildings.

Description

technical field [0001] The invention relates to a composite exterior wall, in particular to a prefabricated thin thermal insulation composite exterior wall, a structural system and a construction method thereof. Background technique [0002] Compared with traditional interior and exterior walls, the existing prefabricated hanging boards generally have the advantages of shortening the construction period and reducing costs. [0003] Especially in reinforced concrete sandwich composite panels, the inner and outer panels are respectively composited on both sides of the thermal insulation material. There are the following main problems in this sandwich composite panel: [0004] 1. The surface layer is thick. Due to the insufficient strength of ordinary concrete, especially the flexural strength is generally only 4-5MPa, considering the external force of the prefabricated hanging slab on the external wall when it is subjected to external forces such as construction hoisting cap...
