REINFORCEMENT FOR CONCRETE COLUMNS.
Specification of Letters Patent.
Application filed November 9, 1307.
Patented Nov. 24, 1908.
SerialNo. 401,376.
To altwhom it may concern:
Be it known that I, ARTHUR A. CLEMENT, a. citizen of the United States, and a resident of Chicago, county of Cook and State of Illinois, have invented certain new and useful Improvements in Reinforcements for Concrete Columns, of which the following is the specification.
The invention relates to metal reinforcements for concrete columns and seeks to provide an inexpensive and efiicient construction for this purpose comprising a spiral wire forming a series of substantially horizontal coils or loops which are arranged near the periphery of the column, together .withqneans for securely holding the coils or rloops in proper spaced relation during the construction of the column.
The invention consists in the features of construction and arrangements of parts here inafter set forth, illustrated in the accompanying drawings and more particularly set forth in the appended claims.
In the drawings Figure 1 is a view in elevation of the improved reinforcement. Fig. 2 is a cross section of the parts shown in Fig. 1. Fig; 3 is a View in elevation of a modified form of the invention. Fig. 4 is a cross section of parts shown in Fig. 3.
It is usual to reinforce concrete columns with horizontal loops or bands arranged near the periphery of the column to resist compression strains and with a series of up.-
right stay bars for resisting bent strains.
The present invention provides an inexpensive arrangement of such a reinforcement and in which the parts are securely held in proper position during the construction of the column.
The horizontal bands or coils a are formed of a continuous spiral or helically coiled wire. These loops are arranged closely adjacent each other and are slightly smaller in diameter than the column for which they are to be used. A column-circular in section is shown in the drawings and the loops or- It is necessary to hol the separate coils or loops ain proper spaced relation during the thereof. The bars b b are preferably formed of fiat strips arranged with their side faces against the coilsa and one of the bars of each pair. (thevinner bar 6 in the form shown) is provided with a series of transverse seats 0 for engaging and securely holding the coils a in proper spaced relation during the construction of the column. These seats.
are preferably formed by transversely crimping the flat bar or strip 6' at proper inter vals. The bars or strips of each pair are secured together preferably by means of clamp loops d which are bent around the bars 5 b and which are arranged at intervals throughout the height of the column between the coils a. These clamp loops are preferably at first of U-form and are placed around the bars I) b and their ends are hammered down into the form shown in the drawings to securely bind the bars together.
The reinforcement is inexpensive to manufacture and the flat spacing bars provided with transverse seats or crimped portions will rigidly hold the coils a at uniform distance apart during the construction of the column so that the latter will be uniformly reinforced at all points.
In the form shown in Figs. 1 and 2, up- 1 right strengthening stay bars 6 are arranged within the coils a and in engagement there with. These stay bars resist any bending strain placed upon the column. In the form shown in Figs. 4 and 5, the stay bars are rigidly secured to the coils so that they are held in place thereby during the construction of the column. Moreover, in this form, the space bars for holding the coils at proper distance apart are secured to the stay bars. In this form, the flat space bars 12 having the transversely crimpcd portions or seats 0 are api'anged a ainst the outer side of the coils a and, as siown, are arranged opposite some of the stay bars e, and are secured theretov at intervals'by the clamp loo s d. Theother stay bars 6 are secured to t e reinforcement by: fiatstrips 7" which are .ar-
.ranged against the outersides of-some of the coils and are secured to the stay bars by clamp loops d. It is only necessary to place the short strips 7 at the upper and lower ends of the reinforcements. In this form, the horizontal reinforcing coils and the vertical stay bars are rigidly connected and securely held in proper relation during the construction of the column. 7
It is obvious that changes may be made in the details set forth without departure from the essentials of the invention.
Having described my invention, what I claim as new and desire to secure by Letters Patent, is:
