United States Patent O 3,183,627 TRANSVERSE WATERSTOP CONNECTION Harry Lawrence Rice, deceased, late of New York, N.Y.,
by Helen Rice, administratrix, New York, N.Y., as-
signor to Rubber and Plastics Compound Co., Ine.,
New York, N.Y.
Filed Oct. 30, 1962, Ser. No. 235,600 1 Claim. (Cl. 50-346) This is a continuation-in-part of Serial No. 847,282, filed October 19, 1959, now abandoned.
The present invention relates to waterproofing barriers used in building brick, concrete or masonry walls. More particularly this invention relates to such barriers which are extruded or formed from plastic materials and which are known as waterstops.
In building construction it is common practice to imbed a ribbon or panel of a plastic and waterproof material between structural elements which are in juxtaposition. This plastic material serves as a waterstop to prevent water seepage between the said elements. The ribbon or panel has ribbed surfaces, the ribs being formed along the lengths of the top and bottom surfaces. These ribs are for the purpose of providing means to cause the ribbon to be gripped securely between the structural elements or between the bricks or in the concrete. Another function of the waterstop is to serve as a resilient cushion between structural walls to absorb the effects of strains caused by vibration or temperature change.
It is common practice in the building art to bend such waterstops around corners since it is very diilicult and sometimes impossible to splice -several pieces perpendicularly to each other because of the irregular contour due to the ribbed surfaces, unless a groove is iirst milled across the surface of the panel, perpendicular to the ribs, to enable the edge of a mating ribbon or panel to be cemented in the groove. Likewise, it is difficult, and frequently impossible, to splice pieces of differing crosssectional contours without leaving paths which are open to water seepage. In addition it is desirable to be able to produce, in situ, a waterstop which is watertight longitudinally and transversely.
It is the object of this invention to provide a conjoined waterstop, and a method of producing the same, which is simple to produce in the field, in situ, during the course of wall construction, and which is completely watertight longitudinally and transversely, whether spliced linearly or at an angle or perpendicularly, and independent of the cross-sectional contours of the waterstops.
According to the present invention, a plastic polygonal rod, preferably of rectangular cross-section, and of a length equal to or greater than the cross width of the waterstop ribbon or panel, and of a height greater than the maximum cross-sectional height of said waterstop ribbon, is cemented or heatsealed to and between the transverse cut edges of the waterstop ribbons which are to be spliced. The rectangular strip besides conjoining the ends of the waterstop ribbons also acts a barrier to interrupt ow of water along the ribs of the spliced sections of the waterstop.
The accompanying drawing shows, for purposes of il- 3,l83,527 Patented May 18, 1955 ICC lustration, two of the many possible embodiments in which the invention may take form, it being understood that the drawing is illustrative of the invention rather than limiting the same. In the drawing:
FIGURE 1 is a perspective view showing the rectangular rod between two cross edges of waterstop panels, linearly.
FIGURE 2 is a perspective view showing the rectangular rod between two cross edges of waterstop panels, perpendicularly.
In the drawing, the waterstop strips, ribbons or panels are designated by the numerals 1 and 2. The rectangular rod is designated by the numeral 3.
In FIGURE l the rectangular rod 3 is shown in such a position that its parallel opposite surfaces 4 and S are brought into Contact with the edges 6 and 7 of the panels 1 and 2, and caused to adhere thereto by means of heat sealing or cementing.
In FIGURE 2 the rectangular rod 3 is shown in such a position that its perpendicular surfaces 8 and 9 are in contact with the edges lil and 1l of the panels 1 and 2, cemented or heat sealed thereto.
The rectangular strip 3 provides a transverse seal to several and different parts of a waterstop or waterstops of varying designs and contours.
The transverse rod shown is preferably produced in the form of a continuous, rectangular or polygonal shaped, extruded plastic rod of a composition which preferably has a lower melting point and a plasticity than that of the composition of the waterstop panels to be joined. This is desirable in order to enable the rod to be joined or welded to the waterstop panels by heat sealing.
The composition of the transverse rod should preferably be such that its physical and chemical properties resemble that of the waterstop panels to be joined, except in regard to melting point and plasticity as hereinbefore described.
The method and product embodied in the present invention has several advantages. The invention obviates the need of undercuts or grooves in the waterstop panels, of the kind usually required to obtain a close matched tit for the several parts of the waterstop in order to prevent the incursion of outside water into the parts of the waterstop joined.
The employment of a rectangular rod of a composition similar to that of the waterstop panels but having a lower plasticity and melting point provides a transverse waterstop seal of good tensile strength when employed in foundation walls.
The extruded rectangular rod, when joined to different component parts of the waterstop along its entire width, encompasses the entire cross-sectional area of the waterstop panels. This feature obviates the need of matching of the contours of the parts to be spliced `or joined. This enables parts of varying contours to be used and contributes a greater degree of anchorage into concrete. Furthermore, the waterstop components can be joined at varying angles to each other without any wastage of material or weakness of seal. Particularly, it provides a transverse seal which makes the waterstop effective against both longitudinal and transverse water seepage.
It is obvious that the invention may be embodied in many forms and constructions and thus is not limited to those shown in the drawings. For example, the shape of the transverse sealing rod may be polygonal and not rectangular,
What is claimed is: i
An extruded strip of plastic waterproof composition for bridging a joint between construction members, said strip having protruding ribs longitudinally on the front and back surfaces thereof, a cross rib laterally acrosssaid longitudinal ribs, said cross rib being of a plastic material having a lower melting point and plasticity than that of the composition of said longitudinal strip, and said cross rib being of a greater height than the height of said longitudinal ribs.
