Description

Technical Field

[0001] This utility model belongs to the technical field of building exterior wall decorative components, and in particular relates to a paint-free, crack-resistant EPS exterior wall component. Background Technology

[0002] EPS exterior wall components are building decoration materials made of flame-retardant polystyrene as the matrix, which are formed by heating and foaming and then combined with alkali-resistant glass fiber mesh and inorganic anti-aging polymer emulsion. They are mainly used for exterior door frames, window frames, eaves and other parts of villas, European-style communities and other buildings. They also have thermal insulation functions and can effectively prevent thermal bridging. They are environmentally friendly and energy-saving decorative materials that can replace traditional cement components.

[0003] Traditional EPS (Expanded Polystyrene) components for exterior walls are typically made by attaching fiberglass mesh to the outside of irregularly shaped EPS foam and then applying mortar using an irregularly shaped scraper. This type of component has two major drawbacks: firstly, it requires a painting process after being attached to the exterior wall, increasing construction costs and time; secondly, when using adhesive mortar for attachment, cracks are prone to occur at the connection between the component and the wall, affecting structural stability and decorative effect, and making it unsuitable for use.

[0004] To address these issues, we provide a paint-free, crack-resistant EPS exterior wall component. Utility Model Content

[0005] The purpose of this utility model is to provide a paint-free, crack-resistant EPS exterior wall component. By using a soft ceramic veneer layer, exposed fiberglass mesh, and crack-resistant mortar layer, it solves the problems of existing EPS exterior wall components requiring secondary coating, which increases costs and construction time, and the easy cracking at the connection between the EPS exterior wall component and the wall surface, affecting stability and decorative effect.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model is a paint-free, crack-resistant EPS exterior wall component, including an EPS exterior wall component body. The EPS exterior wall component body includes an irregularly shaped EPS foam base layer, a crack-resistant mortar layer, a flexible ceramic veneer layer, and an exposed fiberglass mesh. The crack-resistant mortar layer is applied to the outside of the irregularly shaped EPS foam base layer. The flexible ceramic veneer layer is adhered to the surface of the crack-resistant mortar layer. The exposed fiberglass mesh is set at the edge of the irregularly shaped EPS foam base layer and connected to the crack-resistant mortar layer inside the flexible ceramic veneer layer to form a whole.

[0008] The present invention is further configured such that the interior of the flexible ceramic veneer layer is provided with two or more layers of fiberglass felt and fiberglass mesh cloth. The flexible ceramic veneer layer is bent and shaped by a bending machine and is completely attached to the outer surface of the irregular EPS foam base layer. The flexible ceramic veneer layer is used to increase the aesthetics of the main body of the EPS exterior wall component. Moreover, through prefabrication and integral molding, there is no need for secondary processing and application of decorative paint, thus shortening the construction time.

[0009] The present invention is further configured such that the outer surface of the soft ceramic veneer layer is pre-formed with a pre-made decorative coating. The pre-formed decorative coating on the outer surface of the soft ceramic veneer layer can be a decorative coating that imitates metal aluminum plate, stone, etc., eliminating the need for on-site painting and improving construction efficiency.

[0010] The present invention is further configured such that the width of the exposed fiberglass mesh is 5-15cm, and the exposed fiberglass mesh covers the connection between the irregular EPS foam base layer and the wall. The exposed fiberglass mesh can effectively cover the connection seam between the component and the wall, and form an integral reinforced structure by plastering and connecting with the wall surface, thereby improving the crack resistance of the connection part, ensuring stress dispersion and integrity at the connection, and enhancing structural stability and decorative durability.

[0011] The present invention is further configured such that the thickness of the crack-resistant mortar layer is 2-6mm, and the bonding strength with the irregular EPS foam base layer is ≥0.1MPa. The crack-resistant mortar layer with this thickness and bonding strength range provides the necessary connection strength and basic crack resistance of the main structure of the component.

[0012] The present invention has the following beneficial effects.

[0013] 1. This utility model uses a soft ceramic veneer layer and a prefabricated decorative coating to achieve the final decorative effect in one step in the factory production. After the components are installed on the wall, no further painting or finishing treatment is required. This eliminates the cumbersome procedures required for on-site painting, such as scaffolding construction, base treatment, multiple coats of paint, and drying and curing. It greatly simplifies the on-site construction process, shortens the overall exterior wall decoration construction cycle, and saves a lot of labor costs and paint material costs required for on-site painting. It solves the problem of high construction costs and extended construction period caused by the need for secondary painting of traditional components.

[0014] 2. This utility model utilizes exposed fiberglass mesh installed at the edge of the irregularly shaped EPS foam base layer. The exposed fiberglass mesh is firmly bonded to the crack-resistant mortar layer inside the soft ceramic veneer layer to form an integral whole. During construction and installation, the exposed part, together with the crack-resistant mortar, is applied to cover the connection gap between the component and the wall and the surrounding area, forming a continuous reinforced structural layer that spans the component and the wall. This greatly improves the integrity of the connection interface and ensures the long-term structural stability and decorative surface integrity of the component after installation.

[0020] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1

[0022] Please see Figure 1-3 This utility model is a paint-free, crack-resistant EPS exterior wall component, including an EPS exterior wall component body 1. The EPS exterior wall component body 1 includes an irregularly shaped EPS foam base layer 101, a crack-resistant mortar layer 102, a flexible ceramic facing layer 103, and an exposed fiberglass mesh 104. The crack-resistant mortar layer 102 is applied to the outside of the irregularly shaped EPS foam base layer 101. The flexible ceramic facing layer 103 is adhered to the surface of the crack-resistant mortar layer 102. The exposed fiberglass mesh 104 is set at the edge of the irregularly shaped EPS foam base layer 101 and connected to the crack-resistant mortar layer 102 inside the flexible ceramic facing layer 103 to form a whole.

[0023] Specifically: The irregularly shaped EPS foam base layer 101 is prefabricated according to the design shape and serves as the main supporting structure of the component. The crack-resistant mortar layer 102 is evenly applied to the outside of the irregularly shaped EPS foam base layer 101 with a thickness of 2-6mm, which plays a connecting and initial crack-resistant role. The soft ceramic veneer layer 103 is made of soft ceramic material containing two or more layers of glass fiber felt and fiberglass mesh cloth. After being bent into shape by a bending machine, it is completely attached to the outer surface of the irregularly shaped EPS foam base layer 101. The exposed fiberglass mesh cloth 104 is set at the edge of the irregularly shaped EPS foam base layer 101 and is connected to the crack-resistant mortar layer 102 in the soft ceramic veneer layer 103 as a whole. The width is 5-15cm. During construction, it can be scraped to the wall surface to form a cross-type crack-resistant connection and improve its crack resistance effect.

[0024] Example 2

[0025] Please see Figure 1-3 Based on Example 1, the flexible ceramic veneer layer 103 has two or more layers of fiberglass felt and fiberglass mesh inside. The flexible ceramic veneer layer 103 is bent into shape by a bending machine and is completely attached to the outer surface of the irregular EPS foam base layer 101. The outer surface of the flexible ceramic veneer layer 103 is pre-formed with a pre-made decorative coating 105. The pre-made decorative coating 105 adopts a metal aluminum plate, a stone-like material, or other decorative coating. The exposed fiberglass mesh 104 has a width of 5-15cm and covers the connection between the irregular EPS foam base layer 101 and the wall. The thickness of the crack-resistant mortar layer 102 is 2-6mm, and the bonding strength with the irregular EPS foam base layer 101 is ≥0.1MPa.

[0026] Specifically: The flexible ceramic veneer layer 103 is used to enhance the aesthetics of the main body 1 of the EPS exterior wall component. Since it is prefabricated and integrally formed, it does not require secondary processing and application of decorative paint, thus shortening the construction time. The prefabricated decorative coating 105 on the outer surface of the flexible ceramic veneer layer 103 can use decorative coatings such as imitation aluminum plates and imitation stone, eliminating the need for on-site painting and improving construction efficiency. The exposed fiberglass mesh 104 can effectively cover the connection joint between the component and the wall. By applying a trowel, it connects with the wall to form an integral reinforced structure, improving the crack resistance of the connection part, ensuring stress dispersion and integrity at the connection, and enhancing structural stability and decorative durability. The crack-resistant mortar layer 102, with its thickness and bonding strength range, provides the necessary connection strength and basic crack resistance of the main structure of the component.

[0027] The working principle of this utility model is as follows: First, a prefabricated irregular-shaped EPS foam base layer 101 is made according to the design requirements. A crack-resistant mortar layer 102 is then evenly applied to its outer surface. A soft ceramic decorative layer 103, containing two layers of fiberglass felt and fiberglass mesh, is then bent into shape using a bending machine to perfectly match the outer surface of the irregular-shaped EPS foam base layer 101. This layer is then adhered to the surface of the crack-resistant mortar layer 102. Finally, a prefabricated decorative coating 105, resembling stone decoration, is sprayed onto the outer surface of the soft ceramic decorative layer 103 using an automated production line. A 1-meter margin is then left at the edge of the component. The exposed fiberglass mesh 104 with a width of 0cm is integrated with the crack-resistant mortar layer 102. During construction, the main body 1 of the EPS exterior wall component is fixed to the wall surface with adhesive mortar, and then the exposed fiberglass mesh 104 is applied to the wall base with crack-resistant mortar to form an integral crack-resistant connection. The above operation greatly simplifies the on-site construction process, shortens the overall exterior wall decoration construction cycle, and saves a lot of labor costs and paint material costs required for on-site painting. It solves the problem of high construction costs and extended construction period caused by the need for secondary painting of traditional components.
