Abstract
A retaining wall block for an engineered block retaining wall system having an integrally formed head, neck and body, in which one generally planar front face of the body forms a visible part of the wall, the body having two pin holes, two clean out holes, and two pin receiving openings, the pin receiving openings being configured to receive a free end of a lock pin provided in a pin hole of a block placed there under so as to interlock the blocks with a predetermined setback. The pin holes and pin receiving openings being positioned such that a plane extending perpendicular to the generally planar front face passes through one, and only one, of said pin holes or said pin receiving openings.
Description
- This relates to the field of retaining walls and the blocks used to construct retaining walls.
- Retaining walls have been traditionally constructed using natural stone, landscape timbers, masonry block, poured concrete or railroad ties. More recently, engineered concrete block retaining systems have been introduced to the market. Those systems, exemplified by U.S. Pat. No. 7,011,474 to MacDonald, do not use mortar to lock the individual blocks into position but rely instead on methods of locking blocks into position, including specially formed pins. These lock pins include a relatively small diameter body portion that fits into holes formed in the blocks that form a lower course of a retaining wall and a relatively large diameter head portion that sits on top of the block. The next course of block is laid such that the larger diameter head of the lock pin fits into grooves formed in the bottom of the blocks that form the next course of block. Thus, the lock pin secures the two courses together. Other engineered concrete block retaining systems are shown in U.S. Pat. Nos. Re. 34,314, and 4,914,876 (both to Forsberg); 5,294,216 (to Sievert); and 7,168,892 (to MacDonald).
- These products have become popular because they are easy to install, very durable, and can be used to create structurally sound retaining walls at great cost savings. We now describe a retaining wall block that eliminates the need for locking pins having a large diameter head and small diameter body and reduces the weight of the engineered retaining wall block while maintaining the structural integrity of the block and the retaining walls formed of such blocks.

FIG. 1 is a plan view of the top surface of a retaining wall block; -
FIG. 2 is a plan view of the bottom surface of the retaining wall block illustrated inFIG. 1 ; -
FIG. 3 is a perspective view of a retaining wall block; -
FIG. 4 is a top view of three interlocked retaining wall blocks; -
FIG. 5 is a partial front perspective view of a retaining wall built of retaining wall blocks; and -
FIGS. 6A and 6B are top views of alternate ways of laying a first course of five retaining wall blocks. - Referring to
FIGS. 1 to 3 , an engineeredretaining wall block 1 is shown.Block 1 is preferably made of pre-cast concrete, although other suitable materials may be substituted for the concrete.Block 1 has three integrally formed parts, abody 2, aneck 3 and ahead 4. Theneck 3 connects thebody 2 to thehead 4. Thebody 2,neck 3, andhead 4 all extend betweentop surface 5 and abottom surface 6. The top andbottom surfaces block 1 is installed as part of a retaining wall, the forward face 7 ofbody 2 remains visible as part of the wall. - The
neck 3 andhead 4 are formed to reduce the weight ofblock 1, while maintaining structural integrity and support.Body 2 forms the greatest part ofblock 1, with a width of approximately one and ½ feet and a depth of just over 4 inches.Neck 3 is long and narrow by comparison.Neck 3 is narrowed about 4 inches on each side ofbody 2 so as to remain centered onbody 2 and to createshoulder portions body 2. The cross-section ofneck 3 is thus reduced to approximately half the cross-section ofbody 2.Neck 3 extends approximately five and ¾ inches in depth. The weight ofneck 3 is further reduced by forming a rectangular-shaped opening 10 that extends through theneck 3 from thetop surface 5 to thebottom surface 6 ofblock 1.Opening 10 is molded to be approximately 5 inches wide and 6 inches deep, and centered withinneck 3. The forward-mostwall 11 of opening 10 is approximately co-planar withshoulders - First and second receiving
openings body 2 and extend from thetop surface 5 to thebottom surface 6. In the preferred embodiment, each of these openings is approximately one and ⅛ inches thick and 2¾ inches wide. The receivingopenings openings block 1 from thetop surface 5 to thebottom surface 6 saves material costs and effectively reduces block weight so as to further ease placement and installation. - First and
second pin holes body 2. These pin holes are approximately 9/16 inches in diameter and extend approximately 2½ inches intobody 2. These pin holes are designed to accept insertion of pins which are used to interlockblock 1 in position with one or more blocks placed above.Pin holes holes pin holes holes FIGS. 1-3 , are 7/16 inches in diameter and are designed to avoid debris accumulation inpin holes pins pin holes FIG. 3 shows thepins block 1. Without clean outholes pin holes pins - The
pins pin holes openings block 1, when installed, functions together with its neighbors to provide a structurally sound, engineered retaining wall system. - In the preferred embodiment, the rearmost
inner walls openings most wall 11 of opening 10. By contrast, thepin holes block 1 is secured in place on top of the blocks that form the lower course, leaving a ¼ of an inch setback for each successive course of blocks. The setback can be strategically greater or less depending on the appearance of the wall desired. This setback is shown inFIG. 4 . -
FIG. 4 also shows how the placement of thepin holes openings pin holes openings FIG. 4 ,pin holes block 1 ever runs through bothpin hole 14 and receiving opening 12 orpin hole 15 and receivingopening 13. Such a plane could run through one or the other, but not both. As also shown inFIG. 4 , the relative placement of the pin holes and the receiving openings inbody 2 causes thelegs neck 3 of each successive course ofblock 1 to be offset. Thus, just as the front face 7 ofblock 1 will not align with the face of the block above or below that block, neitherleg 18 norleg 19 ofblock 1 will not align withleg 20 ofblock 100 orleg 21 ofblock 200. This offset construction provides structural integrity without interfering with water drainage throughopening 10. - The assembly of blocks to form a retaining wall is best described with reference to
FIGS. 4 and 5 . The lower course of a wall is formed byblocks block 1, described in connections withFIGS. 1-3 , above. Locking pins 16 and 17 are shown in pin holes 14 and 15 ofblock 100 and block 200, respectively.Block 1 is shown on top ofblocks pin 16 inblock 100 is engaged with therearmost wall 18 of receivingopening 12 andpin 17 inblock 200 is engaged with therearmost wall 19 of receivingopening 13.FIG. 4 illustrates howblock 1 is secured in place so as to create a minimum setback of approximately ¼ of an inch while ensuringleg 18 ofblock 1 does not align withleg 20 ofblock 100 below. -
FIG. 5 shows a retainingwall 30 created by installingblock 1 as described in connection withFIG. 4 . As those of skill in the art will appreciate from this drawing, block 1 can be broken in half to finishwall 30. -
FIG. 1 also showsear portions head 4 and angledwall portions body 2.Ear portions - During installation,
ear portions blocks 1 in a concave shaped retaining wall as shown inFIG. 6A . The ability ofblock 1 to be formed in a convex wall shape is also facilitated by the provision ofangled side walls body 2. As an alternative, block 1 can be placed as shown inFIG. 6B to create a convex shaped retaining wall. In the case of a convex shaped retaining wall, the retention ofear portions openings holes block 1 in a concave or convex shaped pattern, while still providing for setback for each successive block course. - Irrespective of the size or shape of the wall constructed by serial placement of
block 1, the depth and resultant stability of the wall is increased by including bothneck 3 andhead 4. In application, opening 10, and the spacing betweenlegs - Various aspects of the different embodiments can be combined in different combinations to create new embodiments. While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
