1 Claim. (Cl. 248354) This invention relates to adjustable columns used'in shoring and other construction work wherein it is desirable to adjust the height of supporting posts and parts thereof, and in particular the invention includes a post formed Wiht two pairs of oppositely positioned angles with the legs of the angles in two crossed planes, one plane being at an angle of 90 in relation to the other, and with one pair of angles slidable over the other.

The invention also includes a shoring head with means for adjustably mounting the shoring head on the post and means for adjustably mounting beam forming elements on the shoring head.

The purpose of this invention is to provide a portable post for use in shoring and concrete form work that may be'taken down after use and reused in which the height thereof may readily be adjusted.

In shoring up under concrete floors and beams wood posts are generally used and cross members are nailed or bolted to the upper ends and when it is desired to change the elevation blocks are driven in under the lower ends. With props of this type it is diflicult to maintain a continuous I level, and when they are knocked down very few of the posts are suitable for reuse. 'With this thought in mind this invention contemplates'a post formed with pairs of angles with one pair slidable over the other and with the angles held by studs and keys in continuous rows'of bolt holes, and with a head having outwardly extending arms carried by the upper ends of the angles,

wherein all of the parts are adjustable and adapted for reuse. I

The object of this invention is, therefore, to provide means for forming extensible shoring post having a shoring head and with a beam form carried by the head.

Figure 2 is a longitudinal section through the shoring head showing the head on the' upper end of a post with the lower part of the post broken away.

posts with angle bars wherein one pair of angle bars is slidable over another and the bars are held in selected positions by studs.

Another object of the invention is to provide means for adjustably mounting a shoring head on a pair of angles with the angles positioned back to back or in the form of a star.

'Another object of the invention isto provide means for mounting a head on one end and a base on the other of a post formed of angle bars with the bars in telescoping relation.

A further object of the invention is to provide a shoring post having a head and a base that is formed with pairs of angle bars in telescoping relation which is of a simple and economical construction.

With these and other objects and advantages in view the invention consists of the new and Figure 1 is a view illustrating an adjustable Figure 3 is a plan view of the shoring head with the post and mounting elements shown therein, taken on line 3-3 of Figure 2. V

Figure '17 is a sectional 'plan through the post and shoring head taken on line l'l'l1 of Fig-" Referring now to the drawings wherein like reference characters denote corresponding parts the improved angle post and shoring head of this invention include a lower pair of angles I and II, an upper pair of angles I2 and I3,

a head I4, a base I5, and studs I6 having slots I1 therein and keys I8. 1

The base I is provided with clip angles I9 and 20 which are secured thereto by welding and the legs of the angles areprovided with bolt holes. 2I and 22 respectively, by which the lower angles I0 and II are secured to the base by the studs I6 and keys I8. The angles I0 and II are secured at intermediate points by lockers 23- as shown in Figures '7 and 23 with the lockers held betweenthe legs of the angles by the studs and keysas shown in Figure 8. The upper angles I2 and I3 which are also held by lockers 23 with studs I5 and keys I8, are adapted to slide over the angles I0 and II, with the flat surfaces of the legs of the angles in sliding engagement, and these angles are securedto the lower angles l2. and I3 in selected positions by the studs Is and keys I8.

The shoring head I4 is also secured to the upper ends of the upper angles I2 and I3 by the studs; and keys I3, and the head is held in position by lockers .24, as illustrated in Figure 6, the lockers having V-shaped sides formed by

plates

25 and 25 that fit between the legs of the angles. The plates 25- and 25 and also the ends 2'! and 28' of the lockers are provided with bolt holes 29 by which they are'held in position by the studs I6 and keys IB. The shoringhead .is U-shape incross section having an upper plate 30 with side plates BI and 32 and the side plates are provided with inclined lower edges sloping upwardlyfrom a lower edge 33 to

ends

34 and 35, and the ends are provided with transverse plates 36 andv 37. provided with

intermediate webs

38 and 39 and a centrally disposed; reinforcing section 50 that has a plate M which rests upon the upper end y:

of the post. The upper plate 30 is provided with groupsof boltholes 42 and 43 in the opposite sides and the side plates 3I and 32 are provided with groups of

openings

44 and 45 adjacent the ends and 45 in the central parts, and as illustrated in Figures 1 and 20, beam forms may be attached to the shoring, heads by the studs through, the openings and 45, and the heads maybe attached to the'posts through the openings 46.

For some uses it is desired to use'a wood beam at the upper end of the post, or attach the post to a wood beam and with thisv thought in mind the device includes a plate-4T having a flange 48 at one side with nail holes 49 therein. and

- provided with clip angles 50, similar to thea'ngles I9 and 25 on: the base I5, on the under surface. The angles 50 are provided with bolt holes 5! through which the, device may be se- The head is also" 4 with the ends held in

holes

58 and 59. The

post 53 is provided with washers 50 which have openings 6| that register with the

holes

58 and 59, and nail holes 62 by which they are held to the post by nails 63. 'Keys 64 are provided in the U-shaped ends of the bolts and the opposite ends are threaded and provided with nuts 65/ The side plates 3| and 32 are also provided 5 with small holes 66 through whichthe shoring head may be secured to wood posts by nails or the like.

With the parts arranged in this manner and with the bolt holes 67 and 68 in the legs of the angles I0 and II, respectively, and 69 and 10 in the legs of the angles I2 and I3, respectively, properly spaced the height of the posts may be adjusted to accurately level a floor or beam and with the parts assembled in this manner it is only necessary to tap the keys-to take the forms down. -The forms and supports therefor may, therefore, be removed without damaging the parts so that they may be reused without repair.

The shoring head and angle post may be used directly under a concrete floor or thelike, or as illustrated in Figures 1 and 20 they may be used to support a form framework, as indicated by the numeral II and this may be adjustably held by the

supports

12 and 13 from the head I4 by the studs I6 and keys I8, as shown. I

i It will be understood that other modifications may be made in the design and arrangement of the parts without departing from the spirit of theinvention.

What is claimed is:

Inanadjustable column, a horizontally disposed'base, a pairof opposed V-shaped clip .ofcoacting angle bars of V'-shape cross section 4 slidably engaging said first pair of angle bars,

the angle bars of said first pair being arranged with their apices facing-each other, and the anglebars of said second pair having their apices facing each other, there being a plurality of spaced registering openings in said angle bars, the openings being arranged in the sides of said angle bars, V-shaped locking members connecting1-the angle bars of said first pair together and; connecting the angle bars of said second pair of angle bars together, studs extending through the registering: openings in said angle I 'bars, there being a slot arranged in each of said studs, a tapered wedge positioned in each ;;,of said slots in said studs, a shoring head detachably' mounted on the upper ends of" said second pair of angle bars.
