.10 Claims.
This invention relates to a metal sealing cap for road parting strips.
The object of the invention is to provide a more eflicient sealing cap and one requiring less metal.
5 Other objects will appear hereafter in connection with the description of the more specific preferred embodiment of the invention illustrated in the accompanying drawings.
The views in the drawings are as follows:
Figure 1 is a perspective view of the cap as applied to a parting strip.
Fig. 2 is a top plan view of the cap.
Fig. 3 is a transverse vertical section through the cap and parting strip.
Fig. 4 is a side elevation of the cap and parting strip.
Fig. 5 is a view similar to Fig. 3 showing a modified form of cap.
The sealing cap is formed from a single sheet of metal such as thin gauge copper, and comprises a central expansible head I, a body 2 consisting of downwardly extending portions on opposite sides of the head, and side flanges 3 for embedding in the concrete slabs of the roadway.
The head I consists of a flattened bead of a width suitable for assisting the troweling of a groove 4 of proper'width in the concrete as illustrated in Fig. 3 for receiving mastic material. By making the bead flat instead of round, it is less apt to become bent or dented in a manner tending to crack the metal.
The body 2 of the cap consists of two spaced side members, one on each side of the head. The members are formed into a narrow neck 5 at the 35 top where they, join the'head and diverge downwardly in an outwardly curved path for a predetermined distance. At the bottom the members merge into the outwardly extending horizontal 4o flanges 3.
The outwardly extending flanges 3 have longitudinal slots 6 therein at intervals spaced longitudinaly of the cap and the metal between the slots and the side edges of the flanges is bent outwardly and twisted through an angle of 90 to provide vertical flanges I which are embedded in the concrete on either side of the cap. By providing the openings 6 behind each vertical flange I, the concrete is allowed to completely embed the flanges 1 to secure the flanges 3 against sliding in the concrete.
The cap fits onto a parting strip 8 which may be of any suitable construction and may have suitable dowel bars 9 forinterlocking the sections or concrete. The strip 8 extends upwardly between the body members 2 and has projections l formed on opposite sides at a predetermined distance from the top to support the cap in a manner preventing contact of the upper edge of strip 8 with theupper part of head I, and to prevent tipping of the cap to one side when concrete is being poured. I
In operation, the sealing cap is intended to pre- 'vent seapage of water through the roadway at the parting line and where the sections of concrete tend to separate for any reason, the flanges l 10 insure that the flanges 3 move with the respective sections while the head I and body members 2 flex. The curvature of the body members 2 allows the members to straighten slightly during flexing thereby relieving the head I and flanges 3 of excessive stress.
The modified construction shown in Fig. 5 has the body portions 2' curved inwardly at the bottom to approximate contact with the parting strip 8. The flanges l are at an oblique angle instead of being vertical as shown in the preferred construction.
Various embodiments may be .employed within the scope of the accompanying claims.
I claim:
