Description

Technical Field

[0001] This utility model relates to the field of building insulation wall technology, and in particular to a prefabricated composite insulation wall. Background Technology

[0002] Conventional buildings typically employ either external or internal wall insulation. External wall insulation is gradually being phased out due to issues such as durability issues (e.g., insulation detachment), lack of fire resistance, and the inability of fire-retardant insulation to meet the insulation requirements of key building sections. Internal insulation, on the other hand, occupies interior space and is susceptible to modification or removal by owners, impacting the overall building insulation performance. Therefore, the development of integrated insulation wall systems is gradually becoming a market trend.

[0003] In existing technologies, the concrete wall and the prefabricated insulation module require on-site processing and installation of anchoring structures during construction, which reduces the efficiency of concrete wall pouring and insulation module assembly. Utility Model Content

[0004] The purpose of this invention is to provide a prefabricated composite insulation wall that solves the problem of inconvenient and rapid assembly between concrete walls and prefabricated insulation modules in conventional insulation walls.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model provides a prefabricated composite insulation wall, including a concrete pouring wall and an external insulation module pre-embedded and connected to the concrete pouring wall through multiple pre-embedded hangers; The external insulation module includes a structural layer, a connecting layer, and an insulation layer disposed between the structural layer and the connecting layer; The embedded lifting component includes a horizontal U-shaped bar and a longitudinal U-shaped bar that is perpendicularly connected to the horizontal U-shaped bar; wherein one end of the horizontal U-shaped bar passes through the connecting layer and the insulation layer and is fixedly connected to the interior of the structural layer; The concrete wall is provided with longitudinal reinforcing bars that penetrate the horizontal U-shaped bars, and also with transverse reinforcing bars that penetrate the longitudinal U-shaped bars; wherein the longitudinal reinforcing bars and the transverse reinforcing bars form a steel mesh.

[0006] In this embodiment, the structural layer further includes a concrete layer prefabricated outside the insulation layer and a metal mesh embedded in the concrete layer; wherein the extended end of the horizontal U-shaped rib is vertically and fixedly connected to the metal mesh.

[0007] Furthermore, in this embodiment, the insulation layer is made of a lightweight insulation material.

[0008] In this embodiment, the connecting layer is a steel mesh disposed between the insulation layer and the concrete pouring wall, and it is connected to the structural layer through the extended ends of a plurality of horizontal U-shaped bars.

[0009] Furthermore in this embodiment, the transverse reinforcement bars and the longitudinal reinforcement bars are tied together to form a steel reinforcement skeleton.

[0010] Furthermore in this embodiment, the steel reinforcement cage is horizontally provided with anchor rods that protrude beyond the designed thickness of the concrete pouring wall, for fixing the pouring template located on the inner side wall of the concrete pouring wall.

[0011] Furthermore in this embodiment, the horizontal U-shaped bar and the longitudinal U-shaped bar are formed by processing the same steel bar.

[0012] Compared with the prior art, the beneficial technical effects of this utility model are as follows: The external insulation module and multiple embedded hangers described in this invention are prefabricated structures. During on-site installation and pouring, they work in conjunction with the pouring template, serving both as the outer shell of the concrete wall and as the external wall insulation layer. Furthermore, the prefabricated embedded hangers utilize horizontal U-shaped reinforcing bars to limit the longitudinal reinforcing bars, and the longitudinal U-shaped reinforcing bars to limit the transverse reinforcing bars. These embedded hangers also enable a fixed connection between the external insulation module and the concrete wall. Attached Figure Description

Detailed Implementation

[0015] This embodiment discloses a prefabricated composite insulation wall, including a concrete pouring wall 2 and an external insulation module 1 pre-embedded and connected to the concrete pouring wall 2 by multiple pre-embedded hangers 3; wherein the external insulation module 1 includes a structural layer 11, a connecting layer 13, and an insulation layer 12 disposed between the structural layer 11 and the connecting layer 13; the pre-embedded hangers 3 include horizontal U-shaped bars 31 and longitudinal U-shaped bars 32 perpendicularly connected to the horizontal U-shaped bars 31; wherein one end of the horizontal U-shaped bars 31 passes through the connecting layer 13 and the insulation layer 12 and is fixedly connected to the interior of the structural layer 11; the concrete pouring wall 2 is provided with longitudinal bars 22 penetrating the horizontal U-shaped bars 31 and transverse bars 21 penetrating the longitudinal U-shaped bars 32. In this embodiment, the horizontal U-shaped bars 31 and the longitudinal U-shaped bars 32 are formed by processing the same steel bar; wherein multiple longitudinal bars 22 and multiple transverse bars 21 form a steel mesh.

[0016] The external insulation module 1 and the multiple embedded hanging parts 3 are prefabricated structures. When installed and poured on site, they cooperate with the pouring template 4 to serve as both the outer shell of the concrete pouring wall 2 and the external wall insulation layer of the concrete pouring wall 2.

[0017] refer to Figure 2 and Figure 3 The prefabricated embedded hanging component 3 can use its horizontal U-shaped bar 31 to limit the longitudinal bar 22, and also use its longitudinal U-shaped bar 32 to limit the transverse bar 21. The embedded hanging component 3 can also achieve the overall fixed connection between the external insulation module 1 and the concrete pouring wall 2.

[0018] In this embodiment, the structural layer 11 includes a concrete layer prefabricated outside the insulation layer 12 and a metal mesh embedded in the concrete layer; wherein the extended end of the horizontal U-shaped rib 31 is vertically and fixedly connected to the metal mesh.

[0019] In this embodiment, the insulation layer 12 is composed of lightweight insulation materials. Specifically, organic insulation materials (such as molded polystyrene foam boards), inorganic insulation materials (such as rock wool boards / rock wool strips), composite and new insulation materials (such as aerogel felt) can be selected. EPS is currently the most mainstream material due to its comprehensive advantages, while XPS and rock wool are important supplementary and alternative choices under higher performance requirements and mandatory fire protection specifications, respectively.

[0020] In this embodiment, the connecting layer 13 is a steel mesh installed between the insulation layer 12 and the concrete pouring wall 2, and it is connected to the structural layer 11 by multiple connecting steel bars.

[0021] In this embodiment, the transverse reinforcing bars 21 and the longitudinal reinforcing bars 22 are tied together to form a reinforcing steel skeleton. The reinforcing steel skeleton is prefabricated with anchor rods that protrude beyond the designed thickness of the concrete pouring wall 2. Specifically, one end of the anchor rod is connected to the longitudinal reinforcing bar 22, and the other end passes through the pouring template 4 to fix the pouring template 4 located on the inner sidewall of the concrete pouring wall 2.
