The present disclosure relates generally to building elements for wall structures. More particularly, the present disclosure relates to a plurality of building elements that are operably coupled to each other to erect a retaining wall.
It is common practice to use prefabricated building elements and particular masonry works such as walls for retaining slopes and slopes along roads, motorways, railways or the like, or for retaining walls for creating drops between urban levels, especially by various types of prefabricated building elements. Such elements usually consist of concrete elements, placed one at the top of the other, and then filled with material such as earth, sand, gravel, and the like. Previous approaches have been developed to building elements for a retaining wall. One example of such an approach is described in U.S. Pat. No. 7,845,885, which is incorporated herein by reference in its entirety.
Currently, building elements require expensive molds and a minimum of one night to rest in the mold to allow time for the material to harden. In addition, the process used to generate a building element results in a building mold with limited variability. Thus, the resulting building element limits the structural variability of the retaining walls that can be constructed using the building element. There is a need in the pertinent art for building elements with increased variability in structure, thereby allowing for increased variability in the structures of retaining walls produced using the building elements.
The disclosure relates to the building of large and heavily loaded retaining walls by a set of prefabricated building elements. Optionally, the prefabricated building elements can include at least two different types of prefabricated building elements. During installation, the building elements can be operably engaged to build a retaining wall. To solidify the retaining wall, earth fillers such as dirt and the like can be used to support the wall.
Disclosed herein are building elements and systems and methods of using building elements to erect a retaining wall. In some aspects, the disclosed building elements can have a modular construction that simplifies production of the building elements and the retaining walls formed by the building elements. In these aspects, it is contemplated that the modular construction increases the ease in which the dimensions and characteristics of a building element can be selectively varied at a particular location within the wall construction to achieve a particular structural need. It is further contemplated that the modular construction can lower production costs, lower investment costs for molds, and ease transport of building elements.
In other aspects, a building element can be configured to be coupled to at least one other building element to form a retaining wall. The building element can comprise a face panel that defines a front surface and a rear surface positioned on an opposing side of the face panel from the front surface. The face panel can comprise a length dimension that is oriented along a first axis, a width/thickness dimension that is oriented along a second axis that is perpendicular to the first axis, and a height dimension that is oriented along a third axis that is perpendicular to the first and second axes. The building element can also comprise at least one beam member coupled to the rear surface of the face panel. The beam member can comprise an upper surface and a lower surface, and at least one surface of the upper surface and the lower surface can define an alignment void that is configured to receive a complementary portion of an adjacent building element. The beam member can also comprise a height dimension oriented along the third axis and a length dimension oriented along the second axis (such that the beam member is substantially perpendicular to the rear surface of the face panel and extends away from the rear surface of the face panel relative to the second axis).
Optionally, in various aspects, the building elements can be engaged to one another using at least one alignment post. The alignment post can comprise a stem and a cap. The stem can have a longitudinal axis and a length dimension along the longitudinal axis. In use, it is contemplated that the longitudinal axis of the stem can be parallel or substantially parallel to the third axis disclosed herein. The cap can comprise a top surface and a bottom surface, wherein the top surface comprises a first cross sectional area and the bottom surface comprises a second cross sectional area. The stem can be coupled to the cap through the bottom surface. In exemplary aspects, a first portion of the stem can be embedded within the cap, with a second portion of the stem extending downwardly and away from the bottom surface.
In other aspects, a plurality of building elements as disclosed herein can be operably engaged to erect a retaining wall system. The retaining wall system can comprise a plurality of building elements, wherein each building element can comprise a face panel and at least one beam member. The face panel can comprise a front surface and a rear surface positioned on an opposite side of the face panel from the front surface. At least one beam member can be coupled to the rear surface of the face panel. The beam member can comprise an upper surface and a lower surface, and at least one surface of the upper surface and lower surface can define an alignment void. The retaining wall system can further comprise an alignment post, and at least a portion of a stem of the alignment post can be configured for receipt within an alignment void of a first building element. Depending upon the orientation of the alignment post, the stem of the alignment post can be received within an alignment void that extends upwardly from the lower surface of the beam member or an alignment void that extends downwardly from the upper surface of the beam member, and a cap portion of the alignment post can be configured to extend either (a) above the upper surface or (b) below the lower surface. A second building element can define an alignment void that is configured to receive the cap of the alignment post when beam members of the first and second building elements are positioned in vertical alignment with one another.
