Benefits of technology
[0015]Further advantages of the wall system are that the panels form walls which are lightweight, easy to install, capable of carrying heavy objects at any location, impact resistant, resistant to cracking, ready to use without plastering or further finishing, sound insulating, heat insulating and fire rated. The Reconstructable Laminated Wall Panel system is suitable for use in indoor and outdoor applications.
Problems solved by technology
The manufacturing of red brick and concrete blocks consumes a great quantity of clay soil and energy.
In addition, the baking and manufacturing of red bricks is prohibited in many locations as it is highly energy inefficient and contaminates the environment.
These materials, however, have the following deficiencies:1. They are unable to support heavy domestic objects, such as bookshelves, cabinets, and air conditioners etc.
As the panel is usually joined using a different compound or even adhesive tape, even slight temperature variations cause panel joint separation again and damage to the joint material.
Plastering of such cracks is an unavoidable cost and such walls require constant maintenance and repair.3. Uneven or imperfect joints or cracking problems as mentioned above in hollow cement wall panels results in a network of cracks, fissures and small spaces.
Hollow and lightweight partitions do not provide good sound nor heat insulation.
Such partitioning systems require further modification (such as installing insulation) to resolve these issues which adds construction time and cost to each job.
The single shell design of CN-Y-2440872 restricts the flexibility of customization as a modular wall panel system in the field, and the tongue and groove system with beveled edges is structurally weak.

Embodiment Construction
[0019]The aim of the present invention is to resolve the above problems by supplying a light-weight, modular wall panel system 10 that is strong enough to carry or support heavy objects, easy to install and environmentally friendly. The present other wall system do not allow the flexibility of attaching hanging or fixed objects to the walls in a simple manner after installation.
[0020]The Reconstructable Laminated Wall Panel System 10 is designed that the central layer or structural layer is comprised of at least one piece of modified gypsum or sand and cement with a fiberglass mesh installed inside and at least one piece of insulating materials, such as polystyrene foam board 3, in between the structural layers. The front and bottom layers include fine sand gypsum or sand and cement boards 2 with fiberglass mesh 1 inside as well.
[0021]This invention, the Reconstructable Laminated Wall Panel 10 has the following advantages over the present commercially available wall panels:[0022]1. ...

Abstract
The present invention relates to a composite sandwich wall panel comprising: at least two fine sand gypsum or concrete panels (I) in each of which a glass fiber web (2) is disposed at center, and at least one polystyrene panel (3), which are bonded alternatively. The surface layer and the bottom layer are the fine sand gypsum or concrete panels, and according to the requirement, the wall panel can be produced to have three or more layers of composite panels. The wall panel of the present invention has advantages of light weight, easy installation, strong loading capacity, no seam crack, no plaster, and good performance of thermal insulation, sound insulation and fireproof as well as it is suitable for internal wall and external wall.
Description
TECHNICAL FIELD[0001]The invention is in the field of building construction and relates particularly to a light-weight modular panel system.BACKGROUND OF THE INVENTION[0002]Historically, walls have been constructed from bricks or blocks. The manufacturing of red brick and concrete blocks consumes a great quantity of clay soil and energy. In addition, the baking and manufacturing of red bricks is prohibited in many locations as it is highly energy inefficient and contaminates the environment. The subsequent replacement materials have been lightweight cement block or board, internal hollow cement wall panels and gypsum board stud walls. These materials, however, have the following deficiencies:[0003]1. They are unable to support heavy domestic objects, such as bookshelves, cabinets, and air conditioners etc. Special fixtures to the wall panel are required in order to support such heavy objects.[0004]2. The panel joints in dry wall and concrete block wall systems are imperfect. As the ...
