SUMMARY OF THE INVENTION This invention is directed to a hollow wall structure and is summarized in the following objects:
First, to provide a hollow wall structure which is particularly suited for the construction of hollow partition walls that may be later disassembled and relocated, the structure involving a minimum number of easily assembled or disassembled parts.
Second, to provide a hollow wall structure including novely arranged fastener strips and cooperating wall studs, the fastener strips having means for slidable attachment to the margins of wall panels and also having mounting clips arranged to be received in slots provided in the wall studs whereupon the fastener strips and their mounting clip may be moved so as to secure the wall panels to the studs.
Third, to provide a hollow wall structure as indicated in the preceeding object wherein a selected panel may be removed by inserting a blade to engage each of its fastener strips to slide the fastener strips and their mounting clips to clear the slots in the corresponding studs.
Fourth, to provide a hollow wall structure as indicated in the preceeding object which includes a novel header construction having downwardly facing retainer channels for receiving the upper margins of the panels as well as permitting limited vertical displacement of a selected panel in the course of fitting the panel in place or removing the panel.

The hollow wall structure utilizes conventional wall panels 1 which are usually formed of gypsum board and are provided with edge grooves or slits 2 in their opposite vertical side margins. The panel is preferably the width between wall studs which are usually spaced 24 inches on center, however, the width may vary or may be doubled or tripled to span several wall studs.
The vertical margins of the wall panels slidably receive fastener strips 3. Each fastener strip includes a channel margin 4 including a flange 5 which is adapted to fit ina slit'2 of a wall panel 1. Each fastener strip preferably extends almost the length of the wall panel and includes a second flange or laterally extended portion 6 which fits contiguous to the margin of the wall panel.
Each fastener strip 3 is provided in the laterally extended portion 6 with a series of vertically spaced sets of clip elements 7. Each set of clip elements comprises two clip elements which are formed by a pair of U- shaped slits 8 extending in opposite directions, one slit extending upwardly, the other slit extending downwardly. The material within each slit is pressed from the normal plane of the laterally extended portion 6 to form an offset portion 9. Extending from the offset portion is an offset tongue 10 which extends essentially parallel to the portion 6 or in slight angular relation thereto.
A plurality of wall studs 11 are provided which are channel shaped in cross section. Each wall stud includes a web 12 joined to mounting sides or flanges 13 having inturned reinforcing extremities 14. Each mounting side 13 is provided with a vertical series of slots 15. Each slot is dimensioned to receive a set of clip elements 7 causing the laterally extended portion 6 to occupy a position contiguous to the mounting side 13. Thereupon the fastener strip 3 may be moved longitudinally relative to the panel 1 and the wall stud 11 to cause the tongue 10 of either clip element 7 to engage a margin of the slot 15.
The wall studs 11 are received in a bottom channel 16 between upwardly extending side flanges 17. The bottom channel is suitably secured to an underlying floor preferably by conventional fastener means not shown and which may be removed. Similar conventional fastener means join the lower ends of the wall studs to the bottom channel or the wall studs may be merely set in place, that is, wedged between the side flanges 17 or the wall studs may be spot welded to the flanges 17.
Fastened to the ceiling in vertical alignment with the bottom channel 16 is a header assembly 18 which comprises outer channel 19 including a web 20 and depending side flanges .21. Secured within the outer channel 19 such as by spot welding is an inner channel 22 having a web 23 and side flanges 24. The side flanges 24 are spaced inwardly from the side flanges 21, a sufficient distance to receive the upper margins of wall panels 1. Also the side flanges 24 have a greater vertical depth than the side flanges 21, and preferably include diverging portions 25.
Installation of the hollow wall structure is as follows:
The bottom channels 16 and the header assembly are placed in vertical alignment. The wall studs which have pairs of slots at each side are spaced center to center the same distance as the width of the wall panels 1. Each wall panel slidably receives a pair of fastener strips 3. The panel is tilted so that its upper end may be inserted between the flanges 21 and 24, and moved upwardly therebetween as the panel is brought into contiguous relation to the stud l1 separated therefrom by the fastener strips 3. The fastener strips are moved upwardly or downwardly to bring the clip elements 7 into registery with the slots 15. The fastener strips 3 may then be moved downwardly, preferably, or upwardly to cause one of the clip elements of each pair to slip over an end of the corresponding slot 15 as shown in FIG. 3.
The side flanges 21 and 24 extend downward a sufficient distance to retain the upper margin of the wall panel after engagement of the clip elements 7 with the lower margins of the slot 15. The diverging portions 25 facilitate reception of the upper margin of the panel when held in an angular position permitting the side margins of the panel to be grasped. Also an angle blade, not shown, may be used as a tool engaging the lower end of the panel for the purpose of raising the panel and then control lowering the panel while the fastener strips 3 are pressed against the mounting sides 13 of the wall studs 11.
The panels 1 are spaced from each other a slight distance equal to the thickness of the metal forming a pair of fastener strips 3. This space can receive a blade 26 equal in width to the metal thickness of a fastener strip. By inserting a blade 26 between a pair of panels below a fastener strip 3, the engaged strip may be raised to disconnect its clip elements 7 from the slots of the corresponding stud. Similarly, by inserting the blade 26 above a fastener strip, the fastener strip may be pressed downward to cause its clip elements 7 to engage the slots 15 of the corresponding stud 11.
The fastener strips 3 are sufficiently shorter than the panels 1 to provide space for insertion of the blades 26 below or above the fastener strips. Because the fastener strips are movable relative to their panels, corresponding slots 15 of the different studs need not be at the same levels. Also, because of the slidable nature of the fastener strips the panels may be readily aligned as they are set in place, without disturbing the interconnection between fastener strips 3 and studs 11.
While for purposes of illustration, a vertical wall partition is disclosed, the structure may form a horizontal wall or ceiling, the wall studs serving as ceiling joists.
