Abstract
Description
Technical Field
[0001] This utility model relates to a roof panel for building construction, specifically a prefabricated insulated roof panel. Background Technology
[0002] Prefabricated construction refers to transferring a large amount of on-site work from traditional construction methods to factories. Building components and accessories (such as floor slabs, wall panels, stairs, balconies, etc.) are prefabricated in factories, transported to the construction site, and assembled on-site using reliable connection methods. Prefabricated buildings mainly include precast concrete structures, steel structures, and modern wood structures. Because they employ standardized design, factory production, assembly-based construction, information management, and intelligent applications, they represent modern industrialized production methods. However, existing technologies have the following problems: In existing technologies, the construction process for concrete roofs is complex, resulting in heavy and high-strength structures. Welding is often used during installation, which is not conducive to later adjustments and leveling. This construction process significantly delays the construction period and is not suitable for large-scale construction. Utility Model Content
[0003] The purpose of this invention is to provide a prefabricated insulated roof panel to solve the problems of complex installation and construction difficulties in the existing technology.
[0004] The technical solution of this utility model is as follows: A prefabricated insulated roof panel includes a galvanized bent frame 1, an insulation layer 2, uprights 3, wire mesh 4, tie nails 5, uprights 6, wire mesh connecting bars 7, bolt connection holes 8, flap holes 9, lifting holes 10, lightweight aggregate concrete 11, crack-resistant mortar layer 12, and decorative layer 13. The galvanized bent frame 1 is positioned between the insulation layer 2 and the decorative layer 13. The uprights 3 within the galvanized bent frame 1 are laid at the bottom layer, and the uprights 6 and wire mesh connecting bars 7 are connected on top. A steel wire mesh 4 is laid on top of the reinforcing bar 3, and then lightweight aggregate concrete 11 is poured. A crack-resistant mortar layer 12 is laid on top of the lightweight aggregate concrete 11, and an insulation layer 2 is installed on the crack-resistant mortar layer 12. The insulation layer is fixed to the lightweight aggregate concrete 11 by several tie nails 5 to increase the stability of the insulation layer 2. A one-way dovetail groove is set on the insulation layer 2, and the steel wire mesh connecting bar 7 extends out of the insulation layer 2. Four bolt connection holes 8 are installed on the side of the galvanized bent frame 1, and flip plate holes 9 and lifting holes 10 are installed on the galvanized bent frame 1.
[0005] The unidirectional dovetail groove structure can bond better with concrete and has better support.
[0006] The beneficial technical effects of this utility model are as follows: This utility model has a simple structure, good heat preservation effect, and the decorative surface can be made of appropriate materials as needed. It is lightweight, high-strength, and fireproof. The heat preservation layer is fixed by tie nails, which makes it less likely to fall off and more stable. It has protruding steel wire mesh connecting ribs on it, which facilitates installation. It is installed through bolt connection holes without welding, which makes it easy to adjust and facilitates construction. Attached Figure Description
