Description

Technical Field

[0001] The utility model belongs to the field of assembled buildings and relates to a structure of a built-in filled sandwich insulation exterior wall. Background Art

[0002] To promote green building materials, my country is actively promoting non-clay bricks and lightweight, large-scale wall materials. Prefabricated wall panels are a crucial component of the industrialized construction process. Their expansion can address labor shortages and high labor costs, and is a future trend. Furthermore, with social development and rising living standards, the demand for energy-efficient buildings is increasing. Traditional building exterior wall insulation methods primarily include exterior wall insulation and interior insulation.

[0003] Exterior wall insulation involves attaching or fixing insulation materials to the exterior of a building's walls and applying a finishing layer. While this approach offers advantages such as effective insulation and ease of installation, it also has drawbacks: It is susceptible to environmental influences, such as rain erosion and sun aging, which can damage the insulation layer, impacting its effectiveness and the building's lifespan. It also impacts the building's aesthetics, particularly in the renovation of older buildings, where exterior insulation can alter the original architectural style.

[0004] Internal insulation refers to the application of insulation materials to the inside of a building's exterior walls. Its advantages are simple construction and low cost. However, it has the following disadvantages: it occupies indoor space and reduces the building's usable area.

[0005] In the prior art, for example, utility model patent No. 2023228801819 discloses a prefabricated sandwich insulated exterior wall panel, comprising an insulation panel and exterior wall formwork located on either side of the insulation panel, a filling cavity formed between the exterior wall formwork and the insulation panel; fasteners disposed between the exterior wall panels; a filler member and a stabilizing rib mesh disposed within the filling cavity, the stabilizing rib mesh extending through the filling member. The stabilizing rib mesh comprises first and second vertical ribs, and horizontal ribs, each extending vertically through the filling member; a tensioning assembly disposed between the second vertical rib and the insulation panel; and horizontal ribs extending horizontally through the filling member. While this structure improves the structural stability of the prefabricated wall, it does not provide adequate protection for the insulation panel, making it susceptible to erosion by factors such as rain and sunlight. Furthermore, the spacing between the insulation panels weakens the thermal insulation effect of the wall.

[0006] Therefore, developing a prefabricated exterior wall structure that has good thermal insulation performance, can prevent the thermal insulation layer from being penetrated, and has a stable structure is a problem that needs to be solved at present. Summary of the Invention

[0007] In response to the above problems, the present invention provides an insulating exterior wall with a built-in filling sandwich, which can prevent the insulation layer of the sandwich from being penetrated and has the characteristics of good thermal insulation performance and stable structure. The specific structure is as follows:

[0008] A built-in filled sandwich insulation exterior wall includes an insulation layer and an exterior wall component surrounded by the insulation layer. The exterior wall component is a rectangular frame. The insulation layer is arranged at the bottom of the rectangular frame. The insulation layer is composed of a plurality of prefabricated insulation blocks arranged closely together. A concrete filling layer is located above the insulation layer. The concrete filling layer fills the internal gap of the rectangular frame, and the top of the concrete filling layer is flush with the top of the rectangular frame.

[0009] Furthermore, the exterior wall component includes:

[0010] Two longitudinal members, one on each side of the insulation layer;

[0011] two transverse members, located at both ends of the insulation layer;

[0012] The steel mesh is arranged on the top of the frame which is formed by two transverse members and two longitudinal members.

[0013] Furthermore, a first notch is provided on the side of the adjacent longitudinal member of the thermal insulation block, and a first overlapping plate overlapping the first notch is provided on the inner side of the longitudinal member.

[0014] Furthermore, multiple insulation blocks are arranged longitudinally along the rectangular frame to form a row of insulation block groups, and the rectangular frame is provided with an insulation layer composed of multiple insulation block groups arranged side by side. Ribs are arranged between two adjacent rows of insulation block groups, and the two ends of the ribs are fixedly connected to two transverse members respectively, and the first notch on the side of the insulation block overlaps the ribs.

[0015] Furthermore, a second notch is provided on the side of the thermal insulation block adjacent to the transverse member, and a second overlapping plate overlapping the second notch is provided on the inner side of the transverse member.

[0016] Furthermore, the thermal insulation block includes a concrete body with a trapezoidal structure and a silicon graphene thermal insulation board located in the middle of the concrete body.

[0017] Furthermore, the ribs, longitudinal members, and transverse members are all connected and fixed by main bars, and the inner sides of the longitudinal members and transverse members are each provided with a plurality of stirrups; the plurality of main bars extend to the outer portion, and the plurality of stirrups are all embedded in the concrete filling layer.

[0018] Furthermore, a steel mesh is arranged on the top of the rectangular frame, and the steel mesh is covered by the concrete filling layer.

[0019] Compared with the prior art, the advantages of the present invention are as follows:

[0020] 1. This utility model sets the insulation layer in the frame formed by the insulation exterior wall and pours concrete on the outside to form a multi-layer protective structure, which "wraps" the insulation layer and effectively prevents it from being directly exposed to the external environment, fundamentally preventing the erosion of the insulation material by factors such as rain and sunlight;

[0021] 2. In the present invention, lap plates are provided on the inner sides of the longitudinal and transverse members, so that the longitudinal and transverse members can be seamlessly connected with the insulation layer. The longitudinal and transverse members and the lap plates form an L-shaped structure, which, combined with the ribs, improves the strength and deformation resistance of the frame.

[0022] 3. The thermal insulation block of the present invention is a concrete body with a trapezoidal structure, and a silicon graphene thermal insulation board is provided in the middle of the concrete body. This structure can protect the silicon graphene thermal insulation board and prevent it from being corroded;

[0023] 4. The thermal insulation blocks in the utility model are tightly combined, which improves the thermal insulation effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] like Figure 1 As shown, a built-in filled sandwich insulation exterior wall includes an insulation layer and an exterior wall component surrounding the outside of the insulation layer. The exterior wall component is a rectangular frame. The insulation layer is arranged at the bottom of the rectangular frame. The insulation layer is composed of a plurality of prefabricated insulation blocks 3 arranged closely together. A concrete filling layer 10 is located above the insulation layer. The concrete filling layer 10 fills the internal vacancy of the rectangular frame, and the top of the concrete filling layer 10 is flush with the top of the rectangular frame. A multi-layer protective structure is formed to "wrap" the insulation layer, effectively preventing it from being directly exposed to the external environment and avoiding erosion of the insulation material by factors such as rain and sunlight. In addition, tailings concrete has excellent insulation performance, which improves the energy-saving level of the building. At the same time, tailings concrete also reduces the overall dead weight.

[0036] like Figure 2 As shown, the exterior wall components include two longitudinal components 1, which are respectively located on both sides of the insulation layer; and two transverse components 2, which are respectively located at both ends of the insulation layer.

[0037] The side of the insulation block 3 adjacent to the longitudinal member 1 is provided with a first notch 5, such as Figure 3 As shown, a first overlapping plate 6 overlapping the first notch 5 is provided on the inner side of the longitudinal member 1. Specifically, the longitudinal member 1 and the first overlapping plate 6 form an integrally formed L-shaped plate.

[0038] Multiple insulation blocks 3 are arranged longitudinally along the rectangular frame to form a row of insulation block groups. The rectangular frame is provided with an insulation layer composed of multiple insulation block groups arranged side by side. Ribs 4 are arranged between two adjacent rows of insulation block groups. The two ends of the ribs 4 are fixedly connected to the two transverse members 2 respectively, and the first notch 5 on the side of the insulation block 3 overlaps the ribs 4.

[0039] like Figure 4 As shown, the insulating block 3 adjacent to the transverse member 2 has a second notch at its bottom adjacent to the transverse member 2. A second lap plate is provided on the inner side of the transverse member 2, overlapping the second notch. Specifically, the transverse member 2 and the second lap plate form an integral L-shaped plate. This improves the strength and deformation resistance of the frame. To facilitate quick installation, the longitudinal members 1 and transverse hooks 2 in this solution are prefabricated. Example 2

[0040] like Figure 1 、 2 As shown, the insulating block 3 includes a concrete body with a trapezoidal structure and a silicon graphene insulation board 3-1 located in the middle of the concrete body. The insulating block 3 is a trapezoidal body, so that the concrete filling layer 10 can more comprehensively cover the insulating block 3, thereby further improving the anti-corrosion effect. Example 3

[0041] like Figure 2 As shown, the ribs 4, longitudinal members 1, and transverse members 2 are all provided with main bars 8. The ribs 4, longitudinal members 1, and transverse members 2 are all connected and fixed by corresponding main bars 8. The inner side surfaces of the longitudinal members 1 and transverse members 2 are each provided with a plurality of stirrups 7. The main bars 8 extend outwards, and the stirrups 7 are all embedded in the concrete filling layer 10. A steel mesh 9 is mounted on the top of the rectangular frame and is covered by the concrete filling layer 10.
