White, Morning Sun, Iowa 52640 Filed .i'an. 24, 1966, Ser- No. 523,844 3 Claims. (Cl. 249-9) ABSTRACT 9F THE DISCLUSURE A recess joint for road construction having a retaining piece thereon which holds tie bars that extend through the recess joint so that the tie bars will not fall out of position during the process of building the forms for the laying of concrete for a section of the road.
This invention pertains to road construction and more particularly to a method and means for building a road having an improved recess joint.
Heretofore in the road construction art the road has been built in longitudinal sections having joints running parallel with the road dividing the sections. This has been done for ease of construction. With modern road building machines the method used is to lay a slab of concrete for one lane of the road and to join to it a second slab of concrete for another lane of the road by a recess joint. The two slabs of concrete that join each other thus maliing up the two lanes of the road are tied together by he bars that extend through the recess joint. Heretofore a great deal of time-consuming labor has been expended in properly placing the tie bars through the recess jolllii.
It is therefore an object of this invention to provide a recess joint which will accommodate tie bars and will hold the tie bars in place during the pouring of the slab of concrete.
It is further an object of this invention to provide a clip on a recess joint which is economical to manufacture and which will be available with the recess joint for use at the road construction site.
It is further an object of this invention to provide a means for road construction utilizing tie bars and recess joints whereby the tie bars are held in position so that they can be straightened and used in connection with the road construction.
Further objects and advantages of this invention will become apparent from the following drawings, descriptions and claims:
In the drawings, FIG. 1 is an isometric view of a portion of a road bed showing a portion of the recess joint and side form in place thereon. FIG. 2 is an isometric view of a portion of the recess joint having the labor saving clip. FIG. 3 shows a modification of the recess joint with a clip cut out of the recess joint, and FIG. 4 shows a further modification of the recess joint with a pin used in place of the clip.
Referring now to the drawings, a portion of a road bed 1 is shown having laid thereon a side form 2. A recess joint 3 has inserted therein a tie bar 4 which is held by a tie bar support 5 that rests on the road bed 1. A stake 6 holds the recess joint 3 against the side form 2. A foot 7 holds the recess joint 3 at the desired elevation from the road bed 1. In FIG. 2 the recess joint 3 is shown with the tie bar 4 in position and held by a clip 8, which is welded to the recess joint 3.
The method to be used for the road construction is to put the recess joints 3 down along the road bed 1. The tie bars 4 are inserted through holes 9 in the recess joints 3. A great number of recess joints 3 are used placed end to end and there are generally four tie bars 4 used per 10- foot section of recess joint 3. After the tie bars 4 are placed through the recess joint 3 they are held in position by the tie bar supports 5 and the clips 3. The next operation is to place the side forms 2 along the recess joints 3 and drive the stakes 6 into the road bed 1 to hold the recess joints 3 against the side forms 2, and the form for the slab of concrete to be poured will .be thus constructed. It can readily be seen that the tie bars 4 will not stay in position unless some means of holding them is devised. The clip 8 thus holds the tie bars 4 in position so that they will not fall down or assume unusual angles. The men who work in connection with laying the side forms 2 and recess joints 3 are thus saved considerable time in going back along the recess joints 3 and straightening up all of the tie bars 4 after the recess joints 3 are placed in position and the tie bars 4 inserted through them.
The slab of concrete is then poured, and ,after it has hardened the side form 2 is removed, the recess joints 3 remain in position and the tie bars 4 are straightened into position as shown by the dotted lines 10. Thus the hardened slab of concrete creates a side form for the slab to be poured next to it. When this is done the tie bars 4 then tie the two slabs together to prevent relative horizonal longitudinal movement between them and the angle in the recess joints 3 creates a further tongue and groove joint to prevent relative vertical movement between the two slabs of concrete.
FIGS. 3 and 4 show modifications of the clips 8 that could be used such as to cut the clip 11 out of a portion of the recess joint 3 as shown in FIG. 3 or to use a pin 12 welded to the recess joints 3 as in FIG. 4.
It can thus be seen that the addition of the clips 8, 11 or the pin 12 to the recess joints 3 will save considerable time and labor in putting the tie bars 4 in place. Clips 8 and 12 could be fastened to the recess joints 3 by any other suitable means than Welding.
I claim:
1. A recess joint for road construction having a channel shaped form member adapted to be placed with its recessed side against a road form, said form member having an aperture to receive a bent tie bar with its bent portion adapted to extend longitudinally along said recessed side, a retaining piece fastened on said recessed side and spaced from said aperture to engage said bent portion of said tie bar.
2. A recess joint -for road construction having a channel shaped form member adapted to be placed with its recessed side against a road form, said form member hav. ing an aperture to receive a bent tie bar with its bent portion adapted to extend longitudinally along said recessed side, a retaining piece cut from said recessed side and spaced from said aperture to engage said bent portion of said tie bar.
