In order to hold the securing plates B in position during erection of the panel, rubber or similar bands d may secure them resiliently or otherwise to the web a of the strip A. The presence of these bands after the boards or panels have been secured is not detrimental but usually being of a light nature and under tension they will break either during the securing of the plates by the screws or not long after.

The securing plates B may be made of metal or any other suitable material and be of any desired shape according to the use of which they are required.

When it is desire-d to secure one section strip A at right angles to another to form a cross member the flanges a of the strips forming the cross member are cut away at the ends a as shown in Fig. 9, so that the bottom of the web a of the cross member will rest on the flanges (1. of the other member.

To secure the ends of two section strips A togcther a horizontal slit a is formed-in each of the abutting ends of the webs a and a fish plate A of channel section of a length equal to that of the two slits (1 see Fig. 9, is inserted into the slots so that when the two ends are brought together as shown in Fig. 10, they are firmly secured by the fish plates. The channel in the fish plate A is of approximately the same width as the thickness of the webs-L of the strips A, the thickness of the horizontal member of the fish plate is approximately equal to the depth of the slits a and the depth of the side members of the fish plate is preferably such that the lower edges are in contact with the surfaces of the flanges a For using the section strip A as an inside ridge finish a plate B with slotted inclined ends I) as shown in Fig. 7 may be employed. The plate Bi fits into one of the slots at in the strip A and the slots in the ends of the plate fit over the web of the inclined transverse strips.

To secure the section strip A to a purlin a bracket e is aflixed to the web a of the strip as shown in Figsli) and 11 and the strip is suspended from the purlin E by this bracket.

A similar method as shown in Figs. 12 and 13 is employed for attaching a section strip or strips A at the sides of a truss F, a bracket f being riveted or otherwise secured to the web a of the strip and the strip suspended from the beam or purlin F to which the truss F is secured.

The section strip may be made of metal, synthetic'resin or other plastic material or it may be built up of laminated paper, wood or other suitable material.

What I claim as my invention and desire to protect by Letters Patent is:

1. Means for securing Wallboards, ceiling boards, panelsand the like in position comprising in combination a T shaped section strip with curing the said edge between the plate and the a perpendicular slot formed in the web member thereof, a securing plate extending through said slot and adjusting means passing through the flange of the section strip from the face thereof and engaging said plate for the purpose of drawing the latter on to the rear surface of the edge of the board and securing the said edge between the plate and the flange.

2. Means for securing wallboards, ceiling boards, panels and the like in position comprising in combination a T shaped section strip with a perpendicular slot formed in the web member thereof, a securing plate extending through said slot and a screw passing through the flange of the section strip from the face thereof and into a tapped hole in the securing plate for the purpose of drawing the latter on to the rear surface of the edge of the board and securing the said edge between the plate and the flange.

3. Means for securing wallboards, ceiling boards, panels and the like in position comprising in combination a T shaped section strip with a perpendicular slot formed in the web member thereof, a securing plate extending through said slot, the securing plate being wider than the slot and formed with a recess at each side to embrace the edges of the slot and a screw passing through the flange of the section strip from the face thereof and into a tapped hole in the securing plate for the purpose of drawing the latter on to the rear surface of the edge of the board and securing the said edge between the plate and the flange.

4. Means for securing wallboards, ceiling boards, panels and the like in position comprising in combination a T shaped section strip with a perpendicular slot formed in the web member thereof and a horizontal slit in an end of the web, a securing plate extending through the said perpendicular slot, adjusting means passing through the flange of the section strip from the face and engaging said securing plate thereof for the purpose of drawing the latter on to the rear surface of the edge of the board and securing the said edge between the plate and the flange and means co-acting with the horizontal slit in the Web to join one section strip to another.

5. Means for securing wallboards, ceiling boards, panels and the like in position comprising in combination a T shaped section strip with a perpendicular slot formed in the web member thereof and a horizontal slit in an end of the Web, a securing plate extending through the said perpendicular slot, adjusting means passing through the flange of the section strip from the face thereof and engaging said securing plate for the purpose of drawing the securing plate on to the rear surface of the edge of the board and sefiange and a channel shaped member, co-acting with the horizontal slit in the web to join one section strip to another.
