Description

Technical Field

[0001] This utility model relates to the field of external wall insulation and building energy conservation technology, specifically to a grouting and bonding external wall insulation 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. 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 applied.

[0005] Technical drawbacks of thin plastering process:

[0006] For new buildings: the standard requires that the bonding surface between the insulation layer and the wall be 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.

[0007] For renovated buildings: the addition of insulation layers increases the external load on the original insulation layers, making it easier for the insulation layers to fall 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 insulation layer fall off more likely.

[0008] 2. Adhesive-anchored composite insulation board process: The insulation layer is first bonded to the rigid decorative panel to form a composite insulation board. During construction, the middle surface of the insulation board is spot-bonded to the wall, and the surrounding decorative panel is then anchored to the wall.

[0009] Technical defects of the adhesive-anchor composite insulation board process:

[0010] 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.

[0011] 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. Utility Model Content

[0012] To address the shortcomings of existing technologies, this utility model provides a grouting and bonding external wall insulation structure, which is suitable for both new and existing building walls. It also provides an external wall insulation structure and construction process that solves the common problems of easy detachment and lack of energy efficiency in building external wall insulation layers.

[0013] To achieve the above objectives, this utility model provides the following technical solution:

[0014] A castable adhesive exterior wall insulation structure includes an exterior wall and an existing building insulation layer. An integrated insulation and decorative panel with a non-removable formwork is provided on the outside of the existing building insulation layer. A cavity is left between the integrated insulation and decorative panel and the existing building insulation layer, and the cavity is filled with castable material. The integrated insulation and decorative panel with a non-removable formwork is fixed to the existing building insulation layer by a connecting component. One end of the connecting component is connected to the exterior wall through the existing building insulation layer via a structural anchor, and the other end of the connecting component is connected to the integrated insulation and decorative panel with a fixing nail.

[0015] The integrated thermal insulation and decorative panel without demolding includes an outer panel and an inner insulation layer; the panel has milled edges around its perimeter; the insulation layer has pre-drilled slots that correspond to the positions of the connecting components; the integrated thermal insulation and decorative panel without demolding has pre-drilled holes around its perimeter, which are semi-circular holes for anchoring nails.

[0016] The connecting assembly consists of two L-shaped plates. One of the L-shaped plates consists of a base and a base vertical plate. The base is in close contact with the existing building insulation layer and has structural anchor holes corresponding to the structural anchors. The base vertical plate has through holes. The other L-shaped plate consists of a component top plate and a top plate vertical plate. The component top plate serves as the anchor base for the anchors, and the top plate vertical plate has elongated adjustment holes. Adjustment bolts pass through the base vertical plate and the top plate vertical plate to position the two L-shaped plates.

[0017] A T-shaped adhesive strip is provided between the heat-insulating and decorative integrated panel without mold removal and the adjacent heat-insulating and decorative integrated panel without mold removal.

[0018] A pressure strip is provided between the anchoring nail and the integrated thermal insulation and decorative panel without the need for mold removal.

One end of the connecting component 4 passes through the existing building insulation layer 2 and is connected to the building exterior wall 1 via a structural anchor 5, and the other end of the connecting component 4 is connected to the integrated insulation and decorative panel (no-removal mold) 3 via an anchor 7. For newly constructed buildings, the building insulation layer 2 may not be required.

[0037] like Figures 2a-2b As shown, the integrated thermal insulation and decorative panel without demolding (3) is composed of an outer panel 3-1 and an inner insulation layer 3-2, and is used as a formwork for cavity casting without demolding. The panel 3-1 is generally made of high-strength materials such as ceramic slabs or cement pressure boards. The panel 3-1 has milled edges 3-3 around its perimeter, which are completed using specialized tools. The panel 3-1 of the integrated thermal insulation and decorative panel without demolding (3) has pre-drilled holes 3-4 around its perimeter. These pre-drilled holes 3-4 are semi-circular holes, facilitating the passage of anchor nails 7, and also serving as temperature deformation adjustment joints between the anchor nails 7 and the integrated thermal insulation and decorative panel without demolding (3).

[0038] The insulation layer 3-2 is generally made of composite national standard insulation materials, such as rock wool and polystyrene particles. The insulation layer 3-2 has a reserved groove 3-5, which is located at the corresponding position of the corresponding connecting component 4.

[0043] like Figure 4 As shown, a T-shaped sealing strip 6 is provided between the integrated thermal insulation and decorative panel 3 (no-removal mold) and the adjacent integrated thermal insulation and decorative panel 3 (no-removal mold). The T-shaped sealing strip 6 is made of flexible sealing materials such as rubber and foam, and its shrinkage, aging and other indicators meet the relevant specifications.
