1 Claim.

One object of the present invention is to pro vide 2. rolled structural metal shape adapted in assembly with other like rolled structural metal shapes for uses among which reference may be made to the re-iniorcement of poles such as telephone and like poles and to caissons, piers and the like.

Other objects of the invention will appear from the following description at the end of which the invention will be claimed.

In the following description reference will be made to the accompanying drawings forming part hereof and in which Figure l is an elevational view of a rolled structural metal shape embodying features of the invention and especially adapted for use in the reinforcement of poles.

Fig. 2 is a side view of the same.

Fig. 3 is a section on the line III-III of Fig. 1 looking in the direction of the arrows, and

Fig. 4 is a transverse sectional view drawn to a reduced scale and illustrating the application of the invention to the re-inforcement of a pole.

Referring to the drawings, the structural rolled metal shape is of T-iorm in cross section. The foot 2 of the T is relatively short and the head 6 of the T is relatively long. The head 6 is provided at one end with an enlarged rib 5, generally circular in cross section, and at the other end the head 6 is provided with an open channel '7 conforming in cross section to the rib 5.

Having in general described the structural shape, it may be said that it can be rolled in any convenient or desirable length.

A description will now be given of the use of the structural shape for the purpose of re-inforcing poles. The foot 2 of the T and the web 3 are extended in one direction and are beveled as shown in Fig. 2 at the lower part thereof to provide a driving edge, and they are extended in the other direction to provide a space for an opening 1 as shown at the upper part of Fig. 1. For re-inforcing a pole several of the described structural shapes with the ribs 5 of adjoining shapes in engagement with the channel '7 are driven into the ground and form a str shown in Fig. 4, with ucture around a pole, as

the feet 2 of the T shapes contacting with the surface of the pole. Then the earth between the pole and the heads 6 of the structural shapes is removed and can be replaced with concrete. Suitable through the holes 1 int iastenings may be passed 0 the pole, thus it will be evident that the base of the pole is well re-inforced and supported. As described the inclosure around the pole is polygonal in cross section but it may be circular in cross section by imparting a slight curvature to the heads 6.

As described the feet the enclosure in order to 2 are arranged inside of support the pole, but they may be arranged outside or" the enclosure when the structural shapes are put to uses that do not involve poles, such as piers and caissons.

the prior art and the quire.

I claim:

A structural metal shape appended claim may reof T form in cross section, the foot of the T being relatively short and the head of the T being relatively long and provided at one end with an enlarged rib generally circular in cross section and at the other end with an open channel conforming in section to the section of the rib.
