Description

Technical Field

[0001] The invention belongs to the technical field of building energy-saving and heat-insulating materials in the building materials industry, and specifically relates to a lightweight heat-insulating and noise-reducing roof strip. Background Art

[0002] As a simple structure with low cost and efficient installation, light steel houses have been in high demand in today's society. The choice of roof structure, as an important part of its overall structure, has an important impact on the processing and use of light steel houses. The application of lightweight insulation roofs is of great significance to speeding up construction progress and reducing energy consumption. At the same time, as people's demand for the comfort of light steel structure houses increases, the requirements for roof waterproofing and noise reduction are becoming more and more stringent.

[0003] After years of development, the light steel house roof structure has a huge product system, but it is still mainly based on lightweight color steel materials. However, these roof structures have the following prominent problems to varying degrees: ① The roof has poor thermal insulation performance, absorbing heat in summer and dissipating heat in winter; ② The roof is made of iron sheet material, which makes a lot of noise on rainy days; ③ The filling material has almost no fire resistance, which can easily cause serious consequences in the event of a fire; ④ The iron sheet has a low bonding strength with the thermal insulation material, and it is very easy to delaminate under extreme climatic conditions.

[0004] Therefore, the present invention develops a lightweight thermal insulation and noise reduction roof strip to address the bottleneck problem faced by the above-mentioned light steel roof structure, providing technical support for building energy conservation and having broad application prospects. Summary of the invention

[0005] The purpose of the present invention is to provide a safe and easy-to-install lightweight thermal insulation and noise reduction roof strip, which provides a guarantee for improving the construction efficiency, comfort of use and reducing the overall cost of light steel roofs. The lightweight thermal insulation and noise reduction roof strip can realize the integrated construction of roof insulation, noise reduction and structure. The roof material is completely prefabricated in the factory, using a composite structure of lightweight concrete, thermal insulation core material and resin tile reinforced by a steel grid. The thermal insulation core material uses a B1 grade fireproof extruded board. The lightweight concrete is located on the left side of the new thermal insulation material, which has both thermal insulation and lightweight structural support. The fire protection level meets the requirements of the building fire protection design specifications. The steel grid reinforcement structure makes the product strong enough to meet the strength requirements of an independent roof. The top resin tile structure greatly reduces the noise intensity caused by rainfall on the basis of meeting the basic waterproof requirements.

[0006] To achieve the above object, the present invention adopts the following design scheme:

[0007] A lightweight thermal insulation and noise reduction roof strip, such as Figure 1As shown, it includes: supporting iron sheet, steel grid, lightweight concrete, bonding mortar, extruded board, and resin tile. The overall structure is made of lightweight concrete, extruded board is used as insulation material, supporting iron sheet is used as roof bottom decoration and connection material, steel grid strengthens the rigidity of strip board, and resin tile is used as waterproof and noise reduction material on the top of the roof. From the bottom to the top, the strip board is composed of supporting iron sheet (coated with interface agent), lightweight concrete, bonding mortar, extruded board (coated with interface agent), steel grid, and resin tile.

[0008] The supporting iron sheet is characterized by being cut from a low-carbon steel plate, having stripes rolled longitudinally along the supporting iron sheet to increase overall rigidity, and having a bending structure at the connection with the frame, such as Figure 2 As shown, it is easy to connect with the roof frame.

[0009] The bonding mortar is characterized by being made by mixing ordinary Portland cement, dried sand, fly ash, latex powder, carboxymethyl ether cellulose, and polypropylene fiber with water in a certain proportion, and being located between the extruded board and the lightweight concrete to achieve transitional bonding.

[0010] The lightweight concrete is characterized in that it is made of ordinary Portland cement, graded dried sand, fly ash, latex powder and refractory foam particles mixed with water in a certain proportion, and is applied on the supporting iron sheet to achieve structural insulation by increasing the thickness of the roof. The mixed foam design in the cement-based material minimizes the weight while increasing the fire resistance of the roof. When a fire occurs in the house, it will not spread from the roof.

[0011] The extruded board is characterized by being a closed-cell honeycomb structure board formed by foaming and extruding polystyrene particles, with a plurality of dovetail grooves on the bottom of the board, and an interface agent coated on the dovetail grooves and the surface of the extruded board to increase the bonding strength between the extruded board and the bonding mortar.

[0012] The steel mesh is characterized in that it is formed by bending and bundling ordinary low-carbon steel bars, the longitudinal bars of the steel mesh pass through the extruded board, bonding mortar, and lightweight concrete layer in sequence, the transverse bars are respectively located on the surface of the extruded board and in the lightweight concrete, and between the resin tile and the supporting iron sheet, the steel mesh is extended into the bending groove at the bending point of the supporting iron sheet, and metal glue is used to bond the steel mesh to the supporting iron sheet.

[0013] The resin tile is characterized by being made of synthetic resin, with a board width of 60 cm, a length cut according to demand, and a corrugated structure along the width direction to facilitate rainwater flow down, and the shock-absorbing property of the resin material reduces the noise generated during the rainwater falling process.

[0014] Through the design scheme, a safe, convenient, lightweight, thermal insulation and noise reduction roof strip is formed, which achieves the integrated functions of thermal insulation, noise reduction and structure. While realizing basic thermal insulation and waterproofing functions, it reduces the noise intensity on rainy days, reduces the overall construction cost, and greatly improves efficiency and indoor comfort.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention combines thermal insulation materials with structural materials to achieve integration of structure and thermal insulation. The thermal insulation materials and the structure are connected together through a steel grid, which improves the overall strength while optimizing the connection between the roof and the frame, achieving high-strength connection and waterproofing functions simultaneously;

[0017] 2. The structural material under the extruded board of the present invention is lightweight concrete, which not only achieves thermal insulation and structural support, but also has fire resistance. If a fire occurs in the house, the fire will not spread along the roof;

[0018] 3. The present invention realizes factory prefabrication of building materials and on-site modular installation and construction, which is beneficial to ensuring construction safety, reducing labor costs, and improving the stability of construction quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figure 1 As shown, first place the cut-to-size extruded board 5 horizontally, open a dovetail groove on the surface of the extruded board 5, and then apply the interface agent, pass the longitudinal reinforcement on the steel grid 3 through the extruded board, spread a 10mm thick bonding mortar 4, tie the transverse reinforcement on the steel grid 3, pour the lightweight concrete 1 after the bundling is completed, and naturally cure for 24 hours. After the lightweight concrete and bonding mortar are initially solidified, apply the interface agent, install the supporting iron sheet 2, and after the interface agent is initially solidified, turn the extruded board 5 over as a whole, apply the interface agent on the surface of the extruded board 5, and bond the resin tile 6 to the extruded board 5. Naturally cure for 24 hours. After 8 days, it can be shipped out after being cut to the specified length. The insulation material in the present invention is extruded board 5 with good insulation performance. The resin tile 6 greatly reduces the noise on rainy days while achieving the waterproof effect. The lightweight concrete 1 plays a structural support and significantly improves the fire resistance of the material. The steel grid 3 passes through the extruded board, bonding mortar, and lightweight concrete 1 to connect with the supporting iron sheet 2. The material bonding strength is significantly improved. When connecting to the frame, self-tapping screws are used to connect the supporting iron sheet 2 and the roof frame, so that a high-strength connection of the roof can be achieved, avoiding leakage problems caused by drilling holes in the roof.
