This invention appertains to new and useful improvements in reinforced concrete constructions and more particularly to a stool or chair of such construction as to not only support the reinforcing element at the proper height in the form but also to define a pocket in the concrete formation exposing the reinforcing element so that an anchorage is afforded from which can be hung ceilings, pipes and other items.

The principal object of the present invention is to provide a stool or chair structure which can be set in the concrete form in association with a reinforcing rod for supporting the rod at the proper height in the form and secondly to define a pocket in the resulting concrete formation, exposing a portion of the reinforcing rod to form an anchorage over which a hooked member can be disposed conveniently for hanging various items.

Other important objects and advantages of the invention wil become apparent to the reader of the following specification.

In the drawings- Figure 1 represents a vertical sectional view through a concrete form and also through a pair of the pocket forming stool or chair with a reinforcing rod disposed therethrough. i

Figure 2 is a fragmentary sectional view taken substantially on the line 2-2 of Figure 1..

Figure 3 is a fragmentary plan view of the structure shown in Figure 2. 1

Figure 4 is a fragmentary detailed sectional View through a reinforcing concrete structure showing the pocket forming stool or chair in use in conjunction with a hanger.

Figure 5 is a sectional view taken substantially on the line 55 of Figure 3.

Figure 6 is a fragmentary detailed sectional view taken throughv a reinforcing rod and the lower section of the pocket forming stool or chair.

Figure 7 is a fragmentary detailed sectional view taken substantially on the line 'l--! of Figure 3. t

Figure 8 is a sectional view taken substantially on the line 8-8 of Figure 4.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 represents the bottom of a form into which concrete is to be poured. Numeral 6-6 in Figure 1 represents generally a pair of the pocket forming stools or chairs through which a reinforcing rod 1 is disposed.

Each of these pocket forming stools or chairs 6 consists of a lower section A and an upper section B. The lower section is of polygonal shape in horizontal section, the same being open at its top and bottom and at its lower edge is provided with outwardly disposed flanges 8 for rest on the form 5, the corners of these flanges 8 being bent down-, wardly to form teeth 9 for biting action in the form 5 to prevent shifting of the stools or chairs 6 when concrete is being poured into the form.

A pair of opposed sides of the lower section A is formed with notches H) for receiving the reinforcing rod 1. The upper section B is in the form of a cap ll closed at its top and of such cross sectional area as to permit snug fitting over the lower section A. The lower edge portion of the cap H is provided with notches ill for receiving the rod 1 as is clearly suggested in Figures 5 and 6.

It can be seen, that the lower sections A are first positioned on the bottom of the form 5 with the teeth 9 driven into the form after which the reinforcing rod 1 is laid across the sections A and engaged into the notches ill thereof. After this, the caps II are disposed over the sections A to assume the position shown in Figure 5.

The stools or chairs 6 are now set in proper position for pouring of the concrete.

After the concrete formation I3 has set, the form ti can be removed and there will be the resulting pocket in the formation with the reinforcing rod 1 traversing the same, the pocket being defined by the corresponding stool or chair 6. In the thus formed pocket a hanger Hi can be disposed with its hook end l5 engaged over the rod 7. Preferably, this hanger l4 has its free end portion threaded as at IE to accommodate a nut I! which can be tightened against the link member l8 which serves as a connector between the parallel portions of the hanger at the hookshaped end. The nut can be tightened so as to bind the link 18 against the reinforcing rod 7.

Thus with this form of hanger and the pocket, ceilings, pipes and other appliances can be hanged in an easy and convenient manner.

It can be seen that the stool or chair 6 serves the two-fold function of supporting the reinforcing element at the proper height in the form and also to form a'pocket in the resulting concrete formation, exposing a portion of the reinforcing element so that access can be had thereto for supporting ceilings, pipes, etc.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

low structure and rod to close the top of the hollow structure and hold the rod in proper relation to the hollow structure.

3. A combined stool and pocket forming device comprising a box-like structure having means whereby a reinforcing rod can be disposed therethrough, said box-like structure being divided into an upper and a lower section, said sections being in telescopic relation and notched at their opposed ends to receive a reinforcing rod.
