Application led January 6, 1929. Serial No. 349,676.
To all lwhom, z't may concern.'
Be it known that I, EARL L. PETERSON, a
citizen of the United States of America, re.
siding at Corona, in the county of Queens, Long Island, and 4State of New York, have invented certain new and useful Improvements in Reinforced Concrete Construction, of which the following is a specification.
My invention relates to reinforced concrete construction, and particularly to concrete pipe reinforced by an imperforate metal pipe embedded therein. Among the features of improvement secured by my 1nvention Varelst. Means for anchoring the concrete to the imperforate metal pipe;
2nd. 'Stiffening ribs secured to the imperforate pipe and reinforcing the latter;
3rd. Longitudinal ribs secured to the imperforate pipe and serving to space from the latter a mesh reinforce when the latter is used for additional reinforcement ofl the concrete;
4th. Ribs secured to the mperforate pipe and suitably shaped to engage and anchor the concrete in which theyare embedded;
5th. Ribs secured to the imperforate-pipe and shaped to receive the members, by which an associated mesh reinforce may be secured in position;
6th. A construction which embodies all of the aforesaid objects in a single type of rib secured to the imperforate'pipe. l Various other features of improvement will be hereinafter pointed out, or are shown in the accompanying drawings, in
which,
Figure l is a longitudinal section through portion of a reinforced concrete pipe in which my invention is embodied in one form;
Fig. 2 is a transverse section therethrough drawn to a smaller scale; Fig. 3 is an enlarged plan of portion of a4 tain the pipe o ,welded thereto at longitudinally spaced in- `and the metal pipe, and unless such a bond .is attained the concrete outer casing or inner lining is apt to crack and drop away from the metal pipe, thus exposing the latter. ,-.ihe object of the present invention is to provide means for anchoring the concrete. to the pipe while at the same time maintaining the latter imperforate for the purpose above mentioned.
In the construction illustrated in the accompanying drawings, I have shown the metal pipe 5 embedded in the concrete, which thus forms an interior lining 4S and Van exterior casing 7 therefor. To anchor the concrete to the pipe I havev provided the latter with a series of circumferentially spaced longitudinally extending ribs 8 and 9 formed by angle irons. In order to mainimperforate, these ribs aretervals as indicated at l0, (Figs. 3 and d). rfhe manner of Welding is immaterial, and in fact may be omitted if some other suitable means be employed to secure the lribs in place. F or example, small brackets may be welded to the pipe and provided with claws beneath which the base of a Tfshaped ribA is engaged. Or the ribs may be held in position by a group of encircling or interior bands provided with positioning lugsjto engage the ribs and hold the same in properly spaced relationship. It 4will be understood of course that Where the construction of the conduit is such that an anchorage ofthe present type is not/needed for both inner and outer faces of the pipe, it may be omitted from one or the other, without depart ing from my invention.
The ribs 8 and 9 are formed in any suitable way to mechanically engage and hold the concrete. 'A simple methodof accomplishing this is to provide the same with ,perforations 11 through which the concrete passeswhen it is cast upon the pipe. The holes thus form anchorages in like manner .'asan undercut rib, projections, or other suitable engaging elements on the. ribs would, if the latter were so shaped.
When the pipe is to be subjected to considerable strain, either externally or internally, it is desirable to providea further reinforce for the concrete inthe form of a mesh. A common type of mesh reinforce is. illustrated comprising circumferential rings or spiral Wire rodsl2f-interconnected by smaller Wire net Work 13. lll/hen such a reinforce is utilized with ribs, such as 8 and 9, the latter perform the very important function of spacing the mesh reinforce uniformly from the face of the pipe, and of affording ready means for anchoring the mesh in place. Thus, short tie Wires 14: may be passed through the holes 1l in the Webs of the ribs 8 and 9 and bound around the circumferential wire rods l2, thus holding the latter accurately in position and preventing their displacement during the casting of the pipe. Of course this anchorage of the mesh to the ribs 8 and 9 still further assists in binding the concrete in position and preventing it from breaking away from the meta-l pipe 5. Of course the mesh reinforce may be used either in the inner lining or in the outer casing of concrete, and it may be utilized on one face Where the ribs are omitted, Without departing from my invention.
It will be seen that the construction which l have described adords a reinforced concrete conduit in which the concrete lining and-facing for the metal pipe are not only securely anchored to the latter, but the metal pipe itself stiifened by the longitudinal ribs 8 and 9, While the construction also affords the decided advantage of properly positioning and anchoring the mesh reinforce with respect to the metal pipe. Some of these advantages are extremely desirable even When the pipe is not maintained imperforate, and as to such advantages l do not Wish my invention'to be regarded as limited to an iinperforate metal pipe.
`While l have described my invention as applied to a conduit, and particularly a conduit for high pressure Work, it is to be understood that the invention, may be embodied in other types of concrete construction. Thus it may be embodied in tanks, chimneys, or other appropriate construction Withinthe scope of my claim of invention, and it is to be understood that the terminology of the appended claims is used by me in a sense broad enough to cover such construction.
I claim- 1. A reinforced concrete conduit comprising an lmperforate metal Vpipe embedded in madera concrete7 and longitudinally extending ribs mechanically attached 'directly thereto and serving to anchor thereto the concrete in which the metal pipe is embedded.
2'. A reinforced concrete conduit comprising an imperforate metal cylinder embedded in concrete, and longitudinally extending ribs Welded tothe face of the pipe and serving to anchor thereto the concrete in which the pipe is embedded.
ln a reinforced concrete conduit, a metal pipe embedded in concrete, longitudinal ribs mechanically attached directly thereto, and a mesh reinforce spaced by said ribs from the metal pipe.
4. ln a reinforced ,concrete conduit, a metal pipe embedded in concrete, longitudinal spacing ribs mechanically attached directly thereto, and a mesh reinforce spaced by said ribs from the metal pipe, together with means for tying said mesh reinforce to the ribs.
5. ln a reinforced concrete conduit, a metalpipe embedded in concrete, longitudinal spacing ribs mechanically attached directly thereto, and a mesh reinforce spaced by said ribs from the'lnetal pipe, together with means for tying said mesh reinforce to the ribs, saidribs being shaped to afford a mechanical anchoring engagement with the concrete in which the pipe is embedded.
(5. A reinforced concrete conduit comprising an imperforate pipe having longitudinal perforated ribs Welded thereto, a mesh reinforce spaced by said ribs from the metal pipe, means for tying the mesh reinforce to the ribs, and concrete embedding said pipe, ribs and mesh reinforce, substantially as described.
7. A reinforced concrete conduit comprising a metal ipe embedded in concrete, independent, longitudinally extending,` circumferentially-spaced, apertured ribs fastened directly to the exterior and interior of the metal pipe and serving to anchor to the latter the concrete in which it is embedded, in combination with an exterior mesh reinforce tied tc said ribs and spaced thereby from the metal pipe.
In testimony whereof I have signed my name to this specification.
EARL L. PETERSON.
