AUNITED STATES PATENT OFFICE.`
PREFORMED EXIEABTSIOIiI'` JOINT.
Application led December 26, 1925, Serial No. IT7308. Renewed May 24, 1928.
This invention relates to improvements in a preformed expansion joint, and refers more particularly to an 'expansion joint which would be adaptable to numerous and varied uses, for instance, in a construction of concrete, brick, Wood, block, and other forms of monolithic pavement or road construction where expansion joints are employed, as well asin the construction of buildings, foundations, bridges, reservoirs, and other types of monolithic concrete construction and wherever the usey of a high grade preformed expansion joint of the character.
herein described, is desirable.
Expansion joint fillers should contain certain inherent characteristics, among which may be mentioned flexibility to allow for proper expansion and contraction, and rigidity to permit economical stacking, shipping, handling and installation.l
The expansion joint of the present invention, possesses Vthese desirable characteristics and properties to a marked degree.
Briefly, the expansion joint of the present invention comprises a reinforcing base of felted, fibrous material preferably recessed intermediate its width, said recesses being filled with a bituminous compound.
Tn the drawings, Fig. 1 is a top plan View illustrating a road or pavement utilizing a pre-formed expansion joint of the present invention.
Fig. 2 is a cross sectional view taken on 1ine2--2 of Fig. l.
Fig. 3 is a similar cross sectional view showing the end sectionsof the reinforcing base as being removable.
Referring more in detail to the drawings, and more particularly to Fig. 2, a reinforcing base referred to as a whole 1 may comprise the body portion 2 and end sections 3 and 4. The reinforcing base may preferably take the form of an I bar as clearly shown, for the purpose of securing desired results. -The body portion 2 is preferably constructed of felted or molded iibrous material, and the en d sections 3 and 4 are preferably of the same material. The
If thc granular surfacing 6 is not desirable, a coating'of talc, clay, mica or similar substance may be applied to the outside surf facing to prevent sticking of the bituminous surface when coming in contact with other surfaces. When using asphalt as a bituminous compound, it should preferably have a melting point of not less than 150 F., more or less,"and not exceeding 300 F. more or less, it having been predetermined that bituminous material Within this range is sufficiently flexible to permit desirable eX- pansion and contraction. This bituminous compound is preferably poured or formed in the recesses while in heated liguid condition. The numeral 7 designates'a fragment of adjacent/'concrete or monolithic pavement, and 8 a fragment of thefground on which the pavement is laid,
It may be desirable in certain instances, to provide a pre-formed expansion joint having one or both end sections removable. Thismay be accomplished by utilizing the construction shown in Fig. 3, of which the end sections designated 3 and 4 respectively, may be removable. These end'sections 3 and 4 may be attachedl to the structure by forcing continuous lengthstof ibrousstock into two ends of a machine which is being used to apply the bituminous compound to thebody portion 2. In this way, the end sections will adhere to the composite structure through the adhesive qualities of the bituminous material.
The thickness of the body portion 2 should preferably be Vnot more, than one-half the thickness of the completed preformed joint.
Therefore, according to the present invention, I .have provided a pre-formed eX- pansion joint which has the desirable characteristics heretofore mentioned. The thickness of the completed pre-formed joint. may var from one-fourth to two inches.
,The thic ness of the body portion 2 may vary from agito 1% inches more or less. I clalm as my' inventlon:
gravel, or other granular sub@ l. A pre-formed fexpansion joint, comprising a reinforcing base of 'elted or molded fibrous material, filled with a bituminous p compound, said base comprising a'body-portion and enlarged end sections, substantially simulating in cross section an 2. A. pre-formed expansion joint, comprisinga reinforcing base of felted or molded fibrous material, lled with a bituminous compound, said base comprising a body portion, and angularly disposed end sections. 'i
3. A pre-formed expansion joint, comprising a reinforcing base of elted or molded fibrous material, filled with a bituminous compound, said base comprising a body portion, and angularly disposed end -moneae sections, which latter are removable relative to the body portion.
LA pre-formed expansion joint, comprising a reinforcing baseof felted or molded fibrous material, filled with a bituminous compound, said base comprising a body portion, and angular-ly disposed end sections simulating an -bar.
5. A pre-formed expansion joint, comprising a reinforcing base of felted or molded ibrous material, comprising a body portion having enlarged ends, the space between opposite ends and adjacent the body portion being illed with a bituminous composition.
