16 Claims.

This invention relates to building construction, and more particularly to walls including ceilings or similar structures wherein studs, joists, or other suitable means are used to support wall facings, such, for instance, as plasterboard and plaster.

Perforated plasterboards, commonly composed of a gypsum composition'core and paper cover sheets, have been used extensively as a plaster base in the construction of .walls and ceilings of buildings. It has been customary to so arrange the boards relative to the supporting framework that the ends of the boards lie in edge abutting relation over the stud or joist, being secured thereto by nails. In some cases the boards are attached to the studs or joists by resilient clips so as to provide a floating wall surface which resists the transmission of sound through the wall and at the same time assists in preventing cracks in the plaster by allowing the studs or.

joists to warp without causing undue strains in the plaster coating.

In the present invention, the preformed perforations in plasterboards may conveniently be used to receive a special resilient nailing clip or fastener for attaching the boards to the supports. When such a clip is used, it is preferable, although not essential, that the joints of the plasterboards should be located between the studs or joists. This arrangement is advantageous in avoiding waste due to cutting of boards. Also it enables the use of the nailing clips of this invention with certain standard perforated boards without additional perforations and without change in the standardized arrangement of the perforations.

An object of this invention, therefore, is to provide a building construction in which a resilient nailing clip engages in a preformed perforation in a plasterboard to resiliently attach the board to a building framework.

Certain standardized plasterboard is commonly made 16 inches wide and 48 inches long and is provided with rows of rather large perforations, each perforation being usually about inch in diameter. The perforations are so distributed over the board that, when the board is applied to studs, joists, or other supports having standard spacing between centers, with the abutting end edges of adjacent boards overlapping a support, the intermediate studs will be between adjacent rows of perforations. The spacing between rows of perforations is a multiple of the standard spacing of supports. Therefore, in the present invention the boards may be applied so that the abutting end joints may be positioned between the supports and a row of perforations will be positioned over each support.

It is, therefore, an object of this invention to provide a wall structure and resilient nailing clips therefor in which the clips may be used in combination with standard perforated board to provide a resiliently mounted plaster base. Also the clips may be used for resiliently support- 5 ing'any type of wallboard having perforations of suflicient size and positioned as required to enable the clips to be nailed into a suitable support.

It is also an object to provide a resilient nail clip for perforated plasterboard in which the clip is self-aligning with the plasterboard irrespective orangular driving of the nail portion of the clip.

A further advantage of the present invention is that the clip may be driven in the same manner as ordinary nails and no tools are required other than the usual workmans hammer. It is unnecessary to learn any new technique in building the wall structure or in applying the fasteners.

Another object of the invention is to provide a resilient clip particularly adapted for board attachment by engagement in a board perforation. A further object of the invention is to prevent the sagging of ceiling plasterboards between joists under the weight of the plaster; also to improve building constructions and clips in other respects hereinafter specified and claimed.

Another object is the provision of a nailing clip of the character described which is cheap to manufacture, easy to apply, and will not easily get out of order.

Fig. 5 is a bottom view of the ceiling shown in t Fig. 4 before the plaster is applied.

Fig. 6 is a perspective view of another embodiment of the nailing clip.

Fig. 7 is an axial sectional view through the embodiment shown in Fig. 6.

Referring to the drawing in detail, the wall or ceiling construction may consist of supports such as joists, studs, or the like, I0, secured at their 3 ends to the framework of the building in the usual manner and extending in spaced, para el;

relation. Plasterboards ll of any suitab terial, such as a gypsum core faced with spaced holes or apertures l2 for the purpose of improving the bond of a layer of plaster I3 subboards.

An important feature of the invention comprises an improved resilient nailing clip for attaching the boards H to the joists ID. This clip I4 is designed for insertion through one of the portion l5 substantially perpendicular to the plane of the board H. A portion of the strap forms a U-shaped flange l6 extending substantially at right angles to the body I! with the end of the strap reversely extended to provide a board supporting flange ll substantially longer than the diameter of a perforation H but narrower in width than the diameter of the perforation. Thus if the hole l2 has a diameter of /4", the flange I! may conveniently be 1%," long and wide. The other end of the strap is formed into a plurality of corrugations or zigzag spaced folds l8, and comparatively large aligned holes l8 are formed in the folds I8. A nail extends through the holes l9 and is positioned so that the head 20a of the nail is engagedbetween the free end 2| of the corrugated portion and the flange l1. Thus, by inserting the clip 54 into a board perforation l2 adjacent a joist l0 and driving on the flange H with a hammer, the nail can be driven into said joist, thus resiliently supporting the boards I! on the joists Hi. The folds i8 provide a spring between the nail head and the joist when the clip is applied as shown in Fig. 3.

The holes IS in the clip are of progressively increasing diameter toward the point 22 of the nail so as to permit free angular movement of the nail in the holes l9 and automatic alignment of the body of the clip with the board. The flange ll, being somewhat narrower than the diameter of hole l2, permits some plaster keys to flow into the hole #2 under trowel pressure, without however interfering with the resilience or the proper alignment of the clip. The flange l1 retains the nail in the clip and prevents plaster from interfering with the proper functioning of the device.

The embodiment shown in Figs. 6 and '7 comprises a cup-like-pressed metal shell 23 having a concave end wall 24 with an axial hole 25 therein substantially larger than a nail shank 28 which extends therethrough. The opposite end of the shell 23 is formed to provide an outwardly extending annular flange 21, and a closure or cap 28 is crimped over this flange as shown at 29. The head 30 of the nail seats in a depression 3| formed in the cap-28. A convex washer 32 on the nail bears against the concave end wall 24 of the shell and a compression spring 33 is confined between the washer 32 and the head of the nail so that the weight of the board and plaster are resiliently supported on the spring when the clip is applied in the manner previously described. The large holel9 permits automatic alignment of the clip with the board when the nail is angularly driven.

In the ceiling structure shown in Figs. 4 and 5, the boards H are preferably arranged with the abutting ends thereof between the joists or studs Ill. The free ends of the boards are connected together by sheet metal clips 36 having outstanding fingers 3Iforming opposed channels for the reception of the edges of the boards. These clips 36 maintain the ends of the boards in the same plane under trowel pressure when the plaster I3 is applied to the exposed face of the boards.

The nailing clips of this invention are espe- -holes [2 and comprises a strap having a body cially advantageous in the construction of cellings as they prevent sagging of the boards between joists under the weight of the plaster. The clips also resiliently attach the boards to the building framework so that the ceiling has a high degree of sound insulating properties. The resilient clips also serve to prevent cracks from forming in the plaster l3 as the joists or studs ill can warp or twist under changing atmospheric conditions without distorting the celling surface.

It will be apparent that the clips of this invention may conveniently be used to support any type of plasterboard and perforations may be preformed as desired or the workman can perforate the board on the job in any manner and in any required location on the board.

It is intended, of course, that the invention should not be limited to the. specific embodiment or embodiments disclosed herein, since modifications may be made, and it is contemplated, there-. fore, by the appended claims to cover any such modifications as fall within the true spirit and scope of this invention.
