13 Claims.

This invention relates to paving construction in which a novel and improved expansion joint unit is provided at intervals to divide the paving into spaced apart sections and the spaced apart secons are joined by a jointed load transmitting device, projecting through the expansion joint unit to hold the sections in proper alignment and prevent the adjacent ends being displaced relatively to each other. The invention further relates to a staking means of novel and improved design for securing the expansion joint unit in place upon a suitably prepared foundation, over which the concrete slabs are poured in place.

The expansion joint unit may be advantageously formed of complementary sections, preferably of somewhat similar construction and hollowed out, so that when fitted together in the paving structure they will provide a hollow chambet. The staking means is of a construction to prevent any access of foreign material into the chamber of the joint, and particularly t exclude the poured cement from interfering with the operation of the jointed load transmitting devices.

For a better understanding of the invention reference is made to the accompanying drawings, in which:

Fig. 1 is a cross-sectional view of a section of pavement provided with an expansion joint unit embodying the invention;

Fig. 2 is a perspective view of one end of a section comprising the expansion joint unit;

Referring to the drawings in which like numerals are used to designate like parts, numeral 1 designates a foundation which has been leveled off or otherwise prepared to receive concrete paving applied in sections 2 which are poured in place over the foundatipn with expansion joint units 3 separating and dividing the sections at spaced intervals. The expansion joint strips are secured in place upon the foundation before the sections 2 are poured around them.

The expansion joint unit is preferably made of any suitable materials. Thermoplastic materials which are readily molded into suitable form and which are plastic or elastic are especially suitable. Rubber and asphalt compositions are particularly suitable. Or the expansion joint unit may be made of more rigid material, such as wood, pulp board, metal or the like which may be treated with a suitable waterproofing material. In order that the expansion joint unit may be light in construction and be readily assembled, it is advantageously made in

complemental sections

4 and 5 which may be similar in construction, each being provided with a marginal flange 6 and any number of intermediate projections I. These intermediate projections may be of a y shape or design but are preferably disposed so that they will be formed, directly opposite the projections on the other section. The marginal flanges surrounding the sections are preferably continuous so that when they are in abutting relation, with the sides having the projections laid face to face, the in: terior of the joint unit will have a chambered portion completely sealed by these marginal flanges which prevent any foreign substances such as water or the like gaining access into the chamber of the joint. Substantially the same result could be obtained by having one of the sec tions constructed as above described and faced with a smooth surfaced closure section, The smooth surfaced closure would seat upon the edge flange and the intermediate projections. The bottom edge of the sectional expansion joint unit may advantageously be provided with a sealing 3 strip 8 of any suitable flexible metal such as copper or the like. This is preferably provided with a beading 9 interposed between corners Iii which are adapted to receive the lower corners of t pa si n Jo t u it and s at i on the no- Extensions H are provided on the sealing member to project and be embedded into the adjacent ends of the concrete sections.

A crown seal 12 is also provided 'for the upper edge of the expansion joint unit. This may be of the same type as the bottom seal, or it may advantageously be made in two parts essentially similar in construction with one part attached to one of the expansion joint sections and the other part attached to the other section. Portions l3 of the sealing parts are positioned to overlap with each other, and other parts M are provided for anchoring with the paving sections. This top seal may be made of any suitable material, it being preferably formed of the same light flexible metal as the bottom seal. The parts [4 may be reenforced by retroverting the end I 5 of the sealing part upon the bent out flange portion l6. An intermediate flange l! is provided extending upward a short distance from the top edge of the expansion joint section, the flange being disposed parallel with the face of the expansion joint section. These provide suitable edges against which a finishing tool may be operated to smooth off the concrete above the joints. These upper sealing parts may be conveniently attached to the upper edges of the expansion joint sections by any suitable means, such as nails I8, disposed at suitable spaced intervals.

If desired the ends as well as the top and bottom of the expansion joint unit may likewise be sealed with a sealing strip similar to that which is employed on the bottom edge or to that which is applied on the upper edge. The chambered sectional expansion joint structure permits the material, when the sections or one of them are made out of compressible material, to be compressed within the chambered portion, thereby preventing the expansion joint material from being squeezed from the space between the paving sections.

The expansion joint units are preferably installed before the paving is poured, and a suitable staking means l9 may be employed for holding the expansion joint unit in place. A staking means disposed at alternate intervals on each side of the expansion joint unit is preferred. A suitable staking means is typified by an angular member provided with one portion 20 adapted to engage the inner side of one of the sections and another portion 2| disposed to project through a recess 22 provided in the section. A recess 23 may be conveniently provided near the end of portion 2! to receive a staking device 24.

With these expansion joint units, it is desirable to provide load transmitting meansfor securing the paving sections 2 in alignment and holding the expansion joint unit in place. This means is preferably in the form of

channel members

25 and 26 having a back portion 21 and side flanges 28 extending therefrom. The ends of the two sections are overlapped with the side flanges facing each other in overlapping relation and alternately disposed, with a fastening means, such as a bolt 29 inserted for holding the plates in position for handling and properly positioning same in the paving. The bolt is fitted so that the flange 28 of the corresponding sections will be close together and provide only a limited pivotal movement upon the bolt. A filler 30 may be conveniently placed within the space between the overlapping ends, thereby requiring a bolt which is merely heavy enough for holding the overlapping sections together while they are being as sembled in position. The jointed structure of mitting device, particularly where a filler block is not used. It is desirable, too, to exclude the concrete from a space around the overlapped ends, and means may be conveniently associated with the staking means IQ for this purpose. Metal means 32 may be formed with a lower blade portion 33 adapted to be driven into the foundation. The upper portion is formed into a box-like structure 34 having

end walls

35 and 36, the latter having a tapered extension 31 that may be driven into the side of the expansion joint unit for holding the stake in place.

Portions

38 and 39 are bent to provide side walls for the box-like structure, these being of the same height as the end walls exclusive of the tapered portion 31. One side of the box-like structure is recessed at 43, cut in the form of a U to conform to the contour of the channel members in order that the stakes may be readily slipped over the ends of the channel members and pressed against the expansion joint unit with the tapered portion 31 biting therein. The staking means not only functions to secure the expansion joint unit and the load transmitting device in position but also to exclude any material flowing into the chamber within the expansion joint unit and into the chamber or space between the overlapping end of the load transmitting sections.

In Fig. 10 there is disclosed a modified form of the staking device illustrated in Figs. 3, 6, 7, 8, 9 and 10. The box-like structure for fitting over the end of the load transmitting device is the same. However, in lieu of the blade 33,

side walls

38 and 39 may be provided with a fin 4| having the. ends 42 disposed at a suitable angle thereto for receiving a stake 43 projected through recesses 44 provided in the ends 42.

Figs. 11 and 12 disclose another staking construction, this being particularly suitable for being driven through the expansion joint unit without any holes being first formed. The staking device is in the form of a clip 45 having one or both ends tapered at 46. Recesses 41 are provided in the ends of the clip sufliciently spaced apart so that stakes 48 may be driven therethrough on either side of the expansion joint unit.

While I have illustrated several embodiments of the invention and described same in detail, it

will be understood that there may be various changes and modifications within the scope of the invention and the appended claims.
