SUPPORT FOR SEPARATING STRIPS Original Filed Feb. 28, 1927 concrete.
Patented Dec. 15, 1936 UNITED STATES Albert C. Fischer, Chicago, Ill., assignor to The Philip Carey Manufacturing Company, a corporation of Ohio Application February 28, 1927, Serial No. 171,570
Renewed December 10, 1931 16 Claims.
My invention relates in general to paving and has particular reference to a convenient and practical means for supporting so-called separating strips as commonly used for separating the divisions of concrete paving.
In referring to separating strips I perhaps should briefly explain just what is meant by the term, so as to avoid any possible confusion. It is a more or less common expedient to divide concrete pavements, or even other concrete structures, into sections so as to avoid possible deterioration of the concrete due to expansion and contraction. These separating strips are sometimes installed every thirty, forty or fifty feet transversely of the road, as an example, and other times a longitudinal strip is used without the transverse strips, or even in combination with the transverse strips.
There are various types of separating strips. Those which are known more often as a separating strip are nothing more than a strip of sheet metal cut to the proper size, and often formed with a so-called tongue on one side and a groove on the opposite side. These metal separating strips quite naturally lack compressible qualities to compensate for expansion of the concrete sections between which they are installed, but they do, however, compensate for contraction of the Sometimes they are installed with their crowning edges fiush with the surface of the concrete, and sometimes they are completely imbedded in the concrete so that their crowning edges, so to speak, terminate below the surface of the concrete. In this capacity they function primarily to develop a line of weakness for controlling cracks due to contraction of the concrete, so that instead of having the cracks occur irregularly over the surface they are developed along certain lines.
Another form of the so-called separating strips is a preformed strip of compressible material, such as, a mixture of asphalt and fibre. These strips are more frequently referred to as expansion joint strips and are installed for the purpose of compensating for expansion as Well as contraction of theconcrete.
So far as my support is concerned it is not confined to any of these various types of separating strips, as in reality they are installed in the concrete in more or less the same fashion, i. e. to say, they must be supported on edge perpendicularly with the concrete poured around opposite sides of the strip.
Since the support in this particular instance has been devised primarily for use in combination with a metal separating strip I have selected this particular form in the accompanying drawing to illustrate the support. In said drawing, Figure l is a detailed view in perspective illustrating one form of the invention in combination with a so-called tongue and groove metal separating strip.
Figure 2 is a detailed perspective viewof the same form of the invention illustrated in Figure 1 in combination with the metal separating strip without the tongue and groove formation.
Figure 3 is a detailed perspective view of an'- other form of the invention shown in combination with that form of the strip illustrated in Figure 2.
Figure 4 is a detailed perspective view of the base clip.
Figure 5 is a detailed perspective view of the crown clip.
Figure 6 is a detailed perspective view of the head portion of .a stake shown in Figures 1 and 2; and I Figure '7 is a detailed perspective view of that form of base clip which is intended to be used when the crowned clip shown in Figure 5 is used. Referring now to the drawing in detail. A represents a metal' separating strip, although as above explained it may be any other form of strip which is intended to be installed in the same way as a metal strip is intended to be. According to Figure 1 the separating strip A is made with an intermediate tongue portion B on one side and a groove portion C on its opposite side. As shown, the strip A is intended to be installed on edge, and it is more or less necessary that it be imbedded in the concrete exactly-perpendicular, otherwise there would be a tendency of one section of concrete to ride up over a confronting section, especially in instances where the tongue and groove form is not used. Not only is it necessary to install the strip perpendicular, but it must be installed in a straight line, otherwise in those forms of separating strips which terminate with their edges flush with the concrete anything but ,a straight line would make an unsightly instal- 'lation.
I have devised a very simple, convenient and practical means to install these strips, and ac.- cording to Figure 1, which is the preferred form I employ a stake 5, preferably a metal stake, having a head 6, so that it may be hit with a sledge and driven into the ground. The head 6, according to the forms shown in Figures 1, 2 and 6 is made with a strip engagingclip formed by the downwardly depending lip I, offset from the side 8 of the stake so as to leave an open slot 9 between the lip and the side of the stake.
The slot 9 is made to receive the crowning edge A on the strip A, so that the stake will stand parallel with the strip A with its point It adapted to be driven into the ground. Arranged at the bottom of the strip A is a base clip II, the same having an opening l2 therein for the reception of the stake 5, and an upturned flange l3 which overlies the side of the strip A opposite from that of the stake 5, with the strip confined between the flange I 3 and the side 8 of the stake.
In using the support the stake and the base clip I I may be assembled with the strip A in any fashion most convenient to the one performing the installation. It makes no difference just how the parts are assembled so longas the plate is supported between the head 6 and the base clip H, with the stake passing thru the opening 12 and into the ground. By driving the stake into the ground the strip A will be securely clamped between the base strip H and the head 5. This clamping effect can be readily appreciated when it is considered that the base clip H is supported on top of the ground and the stake 5 is free to move thru the opening 12, so that while the stake may be driven into the ground the strip A rests upon the base clip H and neither the clip ll nor the strip A go below the ground surface, consequently the driving of the stake will pull the strip A onto the base clip H. y
The base clip II also acts as a support for the strip A and prevents the same from being imbedded in the ground which would ordinarily happen in the absence of the clip II, as the thickness of the strip is so slight as to present a. comparatively sharp edge to the ground surface.
The same efiect is established with that form of the support shown in Figure 3, but in this form instead of using the head 6 to engage the crowning edge of the strip the stake 5 is made with an ordinary head '6 and a crown clip I4 is employed. The construction of the same is 'best illustrated in Figure 5, and it preferably comprises a clip somewhat on the order of the base clip l I, having an opening I2 for the reception of the stake5 and upturned flange I3 and a downwardly depending flange I3 with a space between the upturned flange I3 and the downwardly depending flange l3 so as to leave an. open slot l5 for the reception of the crowning edge of the strip A. The head 6 in the stake 5 acts as a stop so that the crown clip 'l4 cannot slip off the stake, and in this way the clip is covered so that it may engage the crowning edge A of the strip, as shown in Figure 3.
Due to the fact that the use of a crown clip will offset the strip A from the stake 5 it will be necessary, or at least desirable, to slightly change the construction of the base clip for this particular form. Otherwise there will be too much play between the bottom of the strip A and the stake, should a base clip such as .ll be used. To defeat this possibility I make up a base clip H as shown in Figure 7., which will be practically the same as the base clip H, except that aslot I5 is made by bending the metal of the clip upon itself as at l6, and turning up the end of the clip to make a flange IT. The base of the strip A is received in the slot I5 so that the strip is thus supported perpendicularly,
the stake 5 being received in an opening I! the same as the opening l2 in the clip ll.
While I have shown and described a strip with only one support it is, of course, understood that as many stakes and sets of clips may be used at spaced intervals along the length of the strip as will be required.
