2 Claims. (01. 72-118) This invention relates to construction and building materials and it has particular reference to an improved method for the erection of plaster and wall board walls, ceilings and parti- 5 tions and the principal object of the invention resides in the novel method involving the steps,
namely; of assembling rock lath or wall board on the supporting studs whereby they will be capable of slight displacement relative to the studs upon which they are supported and in covering the wall board with plaster material to subjecting the wall, ceiling or partition as the case may be, to considerable strain.
Still another object of the invention resides in the provision of means by which to hold the wall boards for slight expansion and contraction and to accomplish which to the maximum degree, means in the form of a distortabledisc or its equivalent is provided in order that the rigid board holding means will not interfere with relative movements of the mass assembly.
The invention in its simplest form completes several steps in the method of, constructing a plaster wall which will resist, to the maximum degree, contraction and expansion, which causes the plaster coat to crack and shale ofi, leaving exposed the plaster board, which isusually the case when no means, such as provided'by the present invention, is present, to alleviate or-re- 40 move this condition.
With the foregoing and other objects as paramount, the invention has particular reference to the several novel steps involved and to 'which reference will be later made during the course of the following description, taken in connection with the accompanying drawing, wherein:-
Figure 1 is a perspective view, fragmentarily showing a conventional assembly of wall boards as they are applied by use of the present invention.
Figure 2 is a perspective view of a complete embodiment of the invention.
Figure 3 is a side elevational view, showing the three principal elements of the inventiomnamely; the nail, washer andplaster retaining reinforcement.
Figure 4 is a. perspective view, with the mesh reinforcing element removed.
Figure 5 is a fragmentary sectionalview of a my wall or partition showing the invention applied.
Figure 6 is a perspective view showing the invention applied at the joints of the wall board in assembly, and
Figure 7 is a detail view of an individual wall @5 board showing an opening thereinto receive the invention and which opening my be made prior or at the time of assembly and erection of the wall.
Continuing more in detail with the drawing, it go may be here mentioned that in the conventional methods employed in the erection of walls, ceilings and partitions, the wall boards are rock lathing or nailed directly onto the supporting studs, which form the spacing means between the sections of which the wall is comprised. In
so afilxing the boards or lathing, as the case may be, they are restrained against displacement, resulting from contraction or expansion, even to the slightest degree, but contraction and expango sion being inevitable in the plaster coating, due
to changing atmospheric conditions, the plaster cracks and sometimes to such a degree as to cause it to fall and disflgure the wall or partition.
It is desirable and perhaps necessary, in the as construction of a permanent wall, ceiling or partition to so apply the wall board in order that it may yield to the continuous expansion and contraction of the plaster coat, which has a minimum degree of plasticity and will yield under changto lug atmospheric conditions if the fabrication on which it is supported will likewise yield, Unless the latter is the case, contraction and expansion of the plaster coat will result in cracking and otherwise disfiguring the wall. I as The present invention contemplates the provision of a wall board and plaster tie of an extremely simple design, yet very effective in supporting the wall boards on the wall studs, so that they will yield to the continuously changing con 10o ditions of the plaster coat, as a result of changing atmospheric conditions to which the wall is subjected, and thus maintain a wall permanently in good substantial condition, devoid of cracks and blemishes resulting from the condition aforesaid and other attendant conditions not named which are results of a non-yielding fabricationand supporting means for the plaster.
Accordingly, 1 designates the wall stud, while 2 designates the wall board, each being ccnvenall tional with the exception that the wall boards have holes 3 therein, the latter being desirable if not necessary in the erection of a wall in accordance with the present method, as willbe hereinafter explained more in detail.
Figures 2, 3' and d inclusive illustrate the mechanical features by which this method is made nossible and includes primarily the nail a, passing through the center of a disc 5, of metal or any other yielding material. Usually, as an auxiliary attachment to the invention, a square or rectangular piece of mesh 6 is employed to complete the combination. It is pointed out however that while the complete combination is shown in Figure 2, the structure shown in Figure a may meet the requirements of the invention equally as well but, as will be explained later, the wire fabrication or mesh 6 serve the useful purpose of providing a positive tie for the plaster coat 7, against the wall board it is desirable that the plaster coat 7, as well as the board 2 against which the coat is applied be capable of movement enmasse to allow for the slight displacement resulting from expansion and contraction, due in the first case to heat or dampness and in the latter case to cold or dryness.
With this in view, the wall boards 2 are slightly spaced apart at a so that they may have room to move relative to each other. addition to this, the openings 3, of greater diameter than the nails 4 are provided or cut in the wall board when the latter is assembled, to accommodate a nail s, and it is understood that it is preferred that the nail shall not touch any part oi the wall board so that the latter may move vertically, hcrizontally or outwardly from the studs 1. In the latter case the disc or washer 5 will become distorted and it is preferred, for this reason that the disc be comprised of a soft and readily yieldable materiel.
The disc 5, when the nail l is driven into the stud 1, will overlapthe edges oi. the bolts 2, in the manner shown in Figure 5, or will overlap the edges of the opening 3 when it is required to alibi the board 2 by driving the nail through the onenlng 3. in the latter case the disc 5 will coin nletely cover the opening 3 and will prevent filling the opening with plaster which otherwise would be a hindrance to the movements required 02 the.
board under the conditions named.
it is apparent then that it is the disc or washer 5 and in the nail *3 alone that holds the plaster board assembly onto the studs 1 in the erection of the wall, ceiling or partition but even so, the
wall boards are capable of slight movement, which movement results from movement oi. the plaster coating imparted thereto, which are usually so small as to be incleterrninable, yet a deciding factor in the erection and maintenance of a per manent and durable wall construction.
Although the disc 5 is oi relatively small di mentions, the disc including the head oi the nail i required to be of non corrosive material order that rust will. not seep through plaster coating appear on the surface thereof to present an :ly condition. 'lo insure proper adherence oif plaster coat over the disc 5, the wire mesh reintorcement c, is preli reserve nail t will bend and thus yield to the movements of the mass.
While the wire mesh reinforcing element 6 is shown to be of a definite size relative to the companion part, it is obvious that this reinforcing elemerit may be in the form of strips of wire mesh material, continuing the full length of each of the boards 2 and the full width thereof to the abutting ends. This arrangement is not wholly necessary but is mentioned for the reason that it will be adopted as the equivalent under certain conditions where it is found to be desirable.
There is found to exist a certain pressure, due to the expansion and contraction of the plaster coating at or adjacent to corners of a room. To overcome this condition L-shaped reinforcing elements 8, which may be comprised of small rods bent in this shape, are employed and the nail a is driven directly beneath these elements El into the 1 against which they rest, the ends of which being interposed between the wall boards in the manner shown in Figure 1.
Although the invention has been described with great particularity as regards the several steps of the method herein set forth and the means by which the method is made possible, it is understood that it is not intended that the inven tion shall be limited to the specific description and, the showing in the drawing and that certain changes and modifications may be resorted to from time to time as may be considered practicalble, without departing from the sphit and intent oi the invention.
What is claimed is:
l. in swell and partition construction, wall board and plaster tie including means arranged to be driven between the edges of said boards in assembly into the supporting fabrication and carrying means overreaching the edges of said boards for holding the latter for relative contraction and expansion and means likewise carried by said carrying means for receiving the plaster coating and holding the same rigidrelative to the points ofsecurement of said boards.
2. In a wall and partition construction, a Wall board assembly arranged in spaced relationship whereby to receive a rigid element driven into the supporting fabrication oi said assembly, means carried by said rigid element to hold said well board for individual and collective displacement and means also carried by said rigid element for holding a plaster coating applied to said wall hoard assembly in. rigid relationship with said supporting fabrication to allow for contraction and expansion.
