PATENT OFFICE Albert 0. Fisher, Chicago, Ill.
Application October 1;
7 Claims.
The invention accordingly consists in the features, combinations and arrangements of parts whichwill be exemplified in the constructions hereinafter described or claimed for carrying out the above stated object and such other objects as will hereinafter appear in the description.
The aim of the present invention is to provide a composite expansion joint strip having a portion, such as the base portion, of highly resilient material, capped by a crown portion of material which is not so highly resilient as the base portion but is preferably of a material which may be compressible for contraction and expansion in conjunction with the base strip and yet "will not be squeezed from the joint space above the tread surface of the paving. The top and bottom portions are preferably assembled by means of a' mating tongue and groove which will more readily graduate the different characters of the top and bottom portions into a unitary assemblage. An anchoring means, preferably conforming to the tongue and groove edges of the top and bottom portions, may be interposed between said sections.
For a better understanding of the invention ref erence may be made to the accompanying drawings, in which Figure 1 is a cross section view of the upper or crownportion of an expansion joint embodying the present invention;
Figure 2 is a cross section of the lower body portion of the expansion joint;
Figure 3 is a perspective view of an anchoring member adapted to be associated with the expansion joint for securing same to adjacent ends of paving sections;
Figure 4 is a perspective view of a composite expansion joint strip composed of the upper and lower portions illustrated in Figures 1. and 2;
Figure 5 is a paving section showing the composite joint assembled between spaced apart paving sections and having the anchoring member interposed therebetween;
Figure 6 is a view of a paving section like Figure 5 with the addition of a base strip bridging the bottom of the joint space; and
Figure 7 is a view of a paving section showing portions and anchored withthe adjacent paving 1934, Serial N0. 746,338
a modified form of joint between the paving sections.
Referring specifically to the drawings, numeral I designates generally an expansion joint structure composed of a cap portion 2 and a base por tion 3 adapted to be assembled edge to edge in superposed relation. In order to permit this assemblage one of the members, such as the cap strip 2, may be provided with a V-shaped groove 4 and the lower portion may be provided with a corresponding complemental V-shaped tongue 5, adapted to be inserted within the groove of the cap portion when the two portions are superposed inedge to edge relation, as illustrated in Figure 4. This composite expansion joint strip may be interposed between spaced apart paving sections 5 and may also have interposed between the top and bottom portions an anchoring member I. This anchoring membe-igis preferably formed with an intermediate V-shaped portion 8 to conform with the tongue and groove portions in the topand bottom portions of the composite strip. Flanges 9 project from each side of the intermediate V-shaped portion 8 and are of sufiicient extent to project for some extent into the ends of the paving sections 6. In order to secure further and better anchorage of the anchoring strip with the paving sections the flanges 9 may advantageously be provided with any number of recesses I0, through which the concrete is adapted to flow when it is poured in place.
-The anchoring strip has a further function than anchoring the expansion joint strip in place. Bein'g imbedded on each side of the paving sections 6, it provides a closure or seal which precludes any water from below the pavement seeping through the joint spaces to the surface. The lower portion 3 of the composite strip substantially fills the space below the anchoring strip but even though it completely fills the space there might be some seepage of water or moisture from below the pavement to the top thereof. Moreover the lower portion 3 might be eliminated from the paving structure and have said expansion joint unit composed only of the top portion 2 mounted and supported upon the anchoring strip. In such a modified structure the anchoring strip would be particularly useful for preventing moisture from seeping to the surface of the paving. This anchoring strip 1 is preferably made of metal but, of course, could be made of any other material suitable foranchoring the strip to the paving sections and providing a waterproof seal.
The lower portion 3 is preferably of highly resilient material, such as sponged asphalt, sponged rubber or cork, or'other resilient granules mixed within an elastic or resilient binding material. This base portion is preferably made up as a preformed article of manufacture.
The top or crown portion 2 is preferably made of less highly resilient material than the base portion. It may be of rubber or any other mastic material and may like the base portion 3 be premoulded or it may be poured in place after the base portion and/or the anchoring strip has been installed. Due to the highly resilient base portion the expansion joint strip is adapted to be highly compressed without the crown portion being squeezed above the tread surface of the pavement. In other words, because of the highly resilient character of a substantial portion of the composite expansion joint strip, said expansion joint strip is adapted to be compressed within the confines of the space between the paving sections without being squeezed from the space. By having the V-shapecl groove it will be seen that a major portion of the composite strip is made to be highly resilient, although only about one-half of the expansion joint strip is made of highly resilient material. The anchoring strip is preferably of some such metallic material as copper, which is readily flexed and does not impede the compressible and elastic qualities of the expansion joint strip.
In some instances, it may be preferable to have another anchoring strip I I (Fig. 6) inserted at or near the bottom of the paving sections. This strip may be bonded to the endsof the paving.
Figure 7 shows a modified form of joint in which a base strip I4 and top strip I5 may be mounted on side strip I6 of metal, wood, or bituminized fabric. Base strip I4 is provided with an intermediate bead I1 and recesses I8, and top strip I5 is provided with a similar bead I9 and recesses 20. The recesses are preferably of such size that the side strips I6 may snugly fit therein. In this way the top, bottom and side strips may be assembled as a unit without other fastening means inserted in place before the paving sections are poured. Or the joint structure maybe built up in place.
It will be seen that when assembled, a chamber 2| is provided between the top, bottom and side strips. This may be left unfilled or it may be filled with some plastic or resilient material such as that used for strips 2 and 3. The groove beneath the bead Il may if desired be filled with a preformed or poured strip 22 of any suitable material, and a crown strip 23 may be inserted to fill the space above the top anchoring strip I5.
While I have described several e bodiments in detail it will be understood that de led construction is for the purpose of illustration and not as a limitation of the invention. The cap and body portion of the composite expansion joint strip may be made of other materials as well as I claim:
1. A preformed expansion joint adapted for insertion between adjacent sections of a pavement and having va lower body portion of highly compressible material, an upper crown portion of waterproofing material, and means interposed between said lower and upper portions and projecting therefrom to anchor with the paving sections.
2. A preformed expansion joint adapted for insertion between adjacent sections of a pavement and having a lower highly compressible body portion of cellular structure, an upper crown portion of waterproofing material, and means interposed between said lower and upper portions and projecting therefrom to anchor with the paving sections.
3. A preformed expansion joint adapted for insertion between adjacent sections of a pavement and having a lower body portion of highly compressible material, an upper crown portionof waterproofing material, a, complementary tongue and groove formed on adjacent edges of said portions, and means having an intermediate body conforming tothe adjacent edges of the lower and upper portions and adapted to be inserted therebetween and having projecting ends to anchor with the paving sections.
4. A preformed expansion joint adapted for insertion between adjacent sections of a pavement and having a lower body portion of highly compressible material, an upper crown portion of waterproofing material, a complementary V- shaped tongue and groove formed on adjacent edges of said portions, and a sheet having an intermediate V-shaped body adapted to mate with the V-shapedtongue and groove of the upper and lower portion when inserted therebetween and having projecting ends to anchor with the paving sections.
5. A preformed expansion joint adapted for insertion between adjacent sections of a pavement and having a lower body portion of highly compressible material and an upper body portion of waterproofing material, said body portions being formed with V-shaped complementary edges whereby said body portions may without extreme accuracy of shaping be interfitted in assembled relation and said upper body portion being adhered to the structure there below.
6. A preformed expansion joint filler adapted for forming the expansion joint between adjacent sections of a pavement and having a lower support structure formed of highly compressible material, a metallic seal member secured to said support structure and including a simple expansion hump portion having its entire walls extending outwardly in one general direction from the tip of the hump, and a pair of laterally extending flanges extending outwardly adjacent to the ends and most widely separated portions of said hump and adapted to be embedded in the concrete, and an upper crown portion of waterproofing material positioned over said seal, said lower support structure and said crown portion being shaped in conformity to the shape of said metallic seal member and adapted to be disposed adjacent to said member upon the opposite sides thereof.
7. A preformed expansion joint filler adapted for forming the expansion joint between adjacent sections of a pavement comprising a metallic seal member secured to said support structure and including a simple expansion hump portion having its entire walls extending outwardly in one general direction from the tip of the hump, and
rial positioned over said seal, the upper portion of said compressible material and the bottom of said crown portion being shaped in conformity to the shape of said metallic seal member and adapted to be disposed adjacent to said member 5 upon the opposite sides thereof.
