Description

Technical Field

[0001] This utility model relates to the field of external wall insulation and building energy conservation technology, specifically to a cavity-filled insulation wall structure. Background Technology

[0002] As my country's building energy efficiency standards gradually improve, the thickness of external wall insulation layers is increasing, and the anchoring requirements between the insulation layer and the base wall are rising year by year. Whether it is the energy-saving renovation of the exterior walls of existing buildings or the laying of insulation layers in new buildings, my country faces the problem of increased additional load on building walls. Therefore, the anchoring between the insulation layer and the base wall is an important technical measure that affects the overall building quality and safety.

[0003] Current forms and construction techniques of external wall insulation in my country:

[0004] 1. Rock wool thin plastering process: The insulation layer is fully laid on the exterior wall of the building and bonded to the exterior wall. At the same time, the insulation nails are deeply embedded in the base wall for anchoring, which is commonly known as the bonding and anchoring process. After the insulation layer is fully bonded to the wall, plastering is performed to level it, and then the finishing is done.

[0005] 2. Composite insulation board process: The insulation layer is first combined with the rigid decorative panel to form a composite insulation board. During construction, the middle part of the insulation board is spot-bonded to the wall, and the surrounding decorative panel is then anchored to the wall.

[0006] Technical shortcomings of existing external wall insulation structures and construction techniques in my country:

[0007] 1. Rock wool thin plastering process:

[0008] a) New buildings: The standard requires that the bonding surface between the insulation layer and the wall is 70%, that is, there are gaps between the insulation layer and the wall, which increases the wind pressure and makes it very easy for water to leak; the insulation nails anchored to the wall are expansion bolts, that is, the anchoring section is a plastic sleeve, which is prone to slippage and deformation, and can easily cause the insulation layer to fall off.

[0009] b) Old buildings undergoing renovation: The addition of a new insulation layer increases the external load on the original insulation layer, making it more prone to the phenomenon of the insulation layer falling off completely; the insulation nails anchored to the base wall are still plastic expansion bolts, which are longer and have a greater external load, making the base anchor section more prone to slippage and deformation, thus making the phenomenon of insulation layer falling off more likely to occur.

[0010] 2. External insulation board process for composite insulation board technology:

[0011] Whether it is a newly built building or a renovated building, the gaps between the insulation layer and the base wall are more numerous and larger when using spot bonding technology, which makes it easier to generate adverse additional wind loads; using expansion bolts to anchor to the base wall will also cause problems with easy detachment.

[0012] In summary, the core flaw of the original process lies in the series of problems caused by the poor adhesion between the insulation layer and the base wall and the weak anchoring. Spot bonding will inevitably produce gaps, while expansion bolt anchors are a post-anchoring process, which will inevitably lead to slippage and deformation. Summary of the Invention

[0013] This utility model overcomes the technical shortcomings of existing structural forms by adopting a wall structure with cavity-filled insulation material, providing an insulation technology suitable for both new and existing building walls, and solving a series of problems such as easy detachment, cracking, and leakage that are common in building exterior wall insulation layers.

[0014] To achieve the above objectives, the technical solution adopted by this utility model is: a cavity-filled thermal insulation wall structure, including a building exterior wall, an existing building insulation layer, a cavity I, and a non-removable template; the cavity I is provided with a keel, and a retaining piece is provided between two adjacent non-removable templates, the retaining piece being connected to the keel, and the keel being fixedly installed on the outside of the existing building insulation layer.

[0015] The keel is a Z-shaped component with right-angle turns. The upper flange of the keel is installed with bolts and clamping parts, and the lower flange of the keel is installed on the outside of the existing building's insulation layer with structural anchors. The middle keel web I connects the upper and lower flanges. The keel is a one-piece molded component.

[0016] An insulating pad is provided between the keel and the edge clamp, and the edge clamp is a one-piece molded part.

[0017] The upper part of the clamping piece has an I-shaped structure, including an upper clamping plate, a lower clamping plate, and a vertical keel web plate II in the middle. The upper and lower clamping plates form a left cavity and a right cavity on their sides. The lower part of the keel web plate II extends downward and then bends laterally to form a base plate parallel to the keel connection part. The base plate is provided with reinforcing ribs.

[0018] The aforementioned edge-locking component includes two F-shaped components with openings facing away from each other. The bottom of the two F-shaped components is connected through a base plate, and the base plate is parallel to the connection part of the keel. Each F-shaped component includes an upper locking plate, a lower locking plate, and a vertical keel web plate II. The upper and lower locking plates of the two left and right F-shaped components form a left cavity and a right cavity. A cavity II is formed between the base plate and the two keel web plates II. A sealing component is provided on the cavity II, and the sealing component is flush with the exposed surface of the non-removable template.

[0019] The beneficial effects of this utility model are:

[0020] 1. Wide range of applications: It is applicable to both new and existing buildings;

[0021] 2. Cavity-cast insulation material eliminates various problems associated with traditional adhesive insulation layers, such as easy leakage, detachment, and cracking;

[0022] 3. Accessories are easy to prepare and construction is simple;

[0023] 4. Low project cost;

[0024] 5. Meets all relevant national standards for exterior wall insulation design, construction, and acceptance. Attached Figure Description
