Patented Feb. 18; 1936 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to improvements in chairs used to support metal reenforcement at the desired height above the ground in the construc-- tion of concrete highways and the like.
An object of the present invention is to pro vide an improved reenforcement supporting chair of the above kind having a lateral tongue forming a stop for engagement with the ground to determine the height of the bar holding part of the chair above the ground surface.
A further object of the invention is to provide a. one-piece sheet metal chair structure which is extremely rigid in construction and of such simple form as to provide for ready and economical manufacture.
A further object is to provide a one-piece sheet metal chair structure having a pointed lower end to enter the ground, and provided with a seat at its upper end to receive a horizontally disposed reenforcing bar, provision being made whereby the chair may receive hammer blows at its upper end, whereby the chair may be readily driven into the ground without danger of destruction or serious damage thereof.
A still further object is to generally improve chairs for holding and supporting reenforcing bars in the construction of concrete highways and the like.
Other objects and advantages of the invention will become apparent from the following description when considered in connection with the accompanying drawing, in which:-
Figure l is an edge elevational view of a reenforcement supporting chair constructed in accordance with the present invention and oper-- atively supporting a reenforcing bar.
Figure 2 is a side elevational view looking toward the left of Figure 1; and
Figure 3 is a perspective view of the chair shown in Figures 1 and 2.
Referring more in detail to the drawing, the present invention relates to a device for supporting a reenforcing bar 5 a predetermined distance from the ground surface 6 so that it will be embedded in the concrete to be subsequently poured mediate its ends is a lateral tongue l2 adapted to contact with the ground when the pointed lower end portion 9 is driven into the ground, so as to serve as a stop for determining the height of the upper end of the bar supporting chair from the ground surface.
At the upper end of the chair, the web part 1 is provided with a semi-circular notch or recess l3 forming a concaved seat for reception of the reenforcing bar 5. The notch or recess I3 is of a location and size so as to leave a portion of the web part 1 remaining as at 54 at one side of the recess [3 which, in conjunction with the adjacent upper end portion of the adjacent side flange 8 provides an angular prong of very rigid form adapted to receive the blows of a hammer for driving the chair into the ground, without danger of seriously distorting or damaging the chair so that the latter may be re-used many times and maintained in good condition. The side flange 8 at the side opposite the prong I5 is provided at its upper end with an extension I 6 which is normally co-extensive with the adjacent portion of said side flange 8 as shown in Figure 3 and indicated by dotted lines in Figure 2. After the bar 5 has been seated in the recess I3, the extension 16 may be readily bent downwardly and inwardly over the top of the bar 5 so as to effectively hold the latter in place within the seat or recess is, as shown by full lines in Figures 1 and 2. Due to the abruptly tapered intermediate portion l I, the major portion of which enters the ground, a wide bearing or purchase is had in the ground to resist swaying oi the chair laterally of the bar 5, while tongue l2 resists to a great extent lateral movement of the chair in a direction longitudinally of bar 5.
From the foregoing description, it will be seen that I have provided a reenforcement bar supporting chair which is extremely simple and durable in construction, eflicient in use, and capable of being quickly placed in position and se cured to the reenforcing bar.
What I claim as new is:
A supporting chair for reenforcing bars comprising a pointed ground-penetrating stake of channel shape in cross section from end to end and having a segmental recess inv the upper end of its web portion forming a'concaved seat to snugly receive the lower portion of the reenforcing bar, the flange of the chair at one side of said recess having an elongated extension at its upper end adapted to be bent downwardly and inwardly over the exposed upper portion of the reenforcing bar to secure the latter in said seat.
