ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to commercial wall systems that are erected and installed between floor and ceiling structures, and more particularly to a demountable wall system that can be moved from one location to another within a building and which includes a seamless wall structure.
BACKGROUND OF THE INVENTION
Commercial wall systems are widely used today in a variety of commercial buildings. Typically these commercial wall systems are installed between floor and ceiling structures. Their acceptance may be in large part due to a number of factors. But it is clear that these types of commercial wall systems are economical, practical and yield a quality finished wall structure. Moreover, these wall systems are typically built from standard components using standard assembly procedures and techniques. Consequently, the walls are built with precision and as a result their overall quality tends to be at a very high level throughout. Also, commercial wall systems can be very versatile and adaptable. It is known to provide these commercial wall systems in the form of a demountable structure that can be easily moved from one location to another location in the same building.
Typically these commercial wall systems are made up of a frame structure that is designed to receive and retain a series of wall panels that are generally connected within the wall structure edge to edge. Although the wall panels may be pre-covered with some form of a wall covering, they do have one draw back or shortcoming in that the edge-to-edge construction results in a seam at certain intervals along the wall. These seams are often viewed negatively especially when it comes to certain commercial settings, like for example Class A office space.
Therefore, there has been and continues to be a need for a commercial wall system that is both demountable and which includes a seamless and continuous wall structure.
SUMMARY OF THE INVENTION
The present invention entails a demountable wall system having a series of seamless wall panels that are adapted to be mounted between a ceiling and a floor structure and which is adapted to be readily movable from one location to another location between the same floor and ceiling structures. The demountable wall system includes a floor railing disposed adjacent the floor and an elongated ceiling railing detachably connected to the ceiling structure. A series of spaced apart upright wall studs are interconnected between the floor and ceiling railings. Secured along one or both sides of the demountable system is a series of wall panels. Each wall panel includes a face area, back, opposed side edges, and a pre-applied exterior wall covering secured to a central portion of the face area so as to effectively define a pair of uncovered areas on opposite sides of the pre-applied wall covering. Panels are joined side edge to side edge and this creates a seam or interface between respective wall panels. To cover the seams the demountable wall system of the present invention includes a wall covering seam filler strip that is designed to be applied down the seam formed at the interface. Further, the same filler strip is effectively applied to the uncovered areas or strips that flank the seam that have been left uncovered as a result of the fact that the pre-applied wall covering only covers a generally central portion of the face of the wall panel. Thus in the end, there is provided a fully demountable commercial wall system wherein the wall panels are assembled in such a fashion that a continuous and seamless wall covering appears across a substantial distance along the wall system.
In another embodiment of the present invention, the demountable wall system of the present invention is erected according to a particular method or process. In this regard, the individual walls panels are formed with the pre-applied central wall covering before being mounted into the frame structure of the wall system. In this case, the wall panels still include uncovered areas that lie adjacent the respective side edges and outwardly of the pre-applied central wall covering. These prefabricated wall panels are first inserted into the frame of the wall system. Once inserted edge to edge and securely fashioned generally between the ceiling railing and the floor railing, there is formed an exposed seam at the interface of the side edges of the respective wall panels. But once erected, then the seam can be covered by the wall covering filler strip described above. Essentially in an embodiment where the created seams run vertically, a strip of the seam filler is prepared and is pressed over the seam and effectively adhered over the seam and the adjacent uncovered areas of the wall panels. The width of the wall covering filler strip is particularly cut or pre-manufactured so as to match and fit precisely between the two spaced apart pre-applied wall coverings of the adjacent two wall panels.
It is therefore an object of the present invention to provide a demountable wall system that includes a seamless outer wall structure.
A further object of the present invention is to provide a method or process of erecting and assembling a demountable wall structure in such a fashion as to create a seamless and continuous outer wall along one or both sides the wall structure.
Other objects and advantages of the present invention will become apparent and obvious from a study of the following description and the accompanying drawings which are merely illustrative of such invention.
