Framed modular ballast block and method of construction

Abstract

A ballast block has a uniquely designed framework consisting of lightweight, pre-fabricated, metal panel members and cross-bracing and elongated bracing members. The various components of the ballast block framework are compactly bundled and shipped to the end use location for assembly on-site. Once assembled, the ballast block framework is properly positioned on its permanent, end use location and concrete or equivalent ballast material is poured into the framework, completely filling its internal space. The ballast block can be sized and fabricated for the specific desired purpose.

Description

BACKGROUND OF THE INVENTION

Ballast blocks and similar anchoring and building blocks are commonly used for a variety of structures and purposes. One such important use of ballast blocks are as foundational mounts to support solar panels and their supporting systems. There is currently no ballast block member or means of fabricating a ballast block which accomplishes this need and which also is relatively easy to construct and has the versatility of selective placement at the end use location.

SUMMARY OF THE INVENTION

Specifically, the present invention relates to the design and construction of framed ballast blocks for anchoring upstanding structures, e.g. solar racking and communication towers, against meteorological and geological events. Such ballast blocks can also be used for highway barricades, protection against beach erosion, building foundations, boat and ship docks, and other applications which require high strength, stable ballast supports or protective structures.

The ballast block of the present invention comprises a uniquely designed framework consisting of lightweight, pre-fabricated, metal panel members and cross-bracing and elongated bracing members. The various components of the ballast block framework are compactly bundled and shipped to the end use location for assembly on-site. Once assembled, the ballast block framework is properly positioned on its permanent, end use location and concrete or equivalent ballast material is poured into the framework, completely filling its internal space. The ballast block can be sized and fabricated for the specific desired purpose.

The ballast block of the present invention provides a low cost, lightweight framing structure which is conveniently and easily shipped, located, and assembled right at the end use site. Once set in place and filled with concrete or other heavy ballast material, it provides a stable and effective foundation.

The novel features which are considered as characteristic of the invention are set forth in particular in the appended claims. The invention, itself, however, both as to its design, construction and use, together with additional features and advantages thereof, are best understood upon review of the following detailed description with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

Ballast block 1 of the present invention comprises framework 2 having first panel member 4 and second panel member 14. First panel ember 4 comprises sidewall section 6 extending the length of framework 2 of ballast block 1, first end wall section 8, and second end wall section 10. End wall sections 8 and 10 are connected by perforated hinges 12 and 13 to sidewall section 6 and are folded inward at the hinges so that they are positioned at a 90° angle to the sidewall section. In like manner, second panel member 14 comprises sidewall section 16 extending the length of framework 2 of ballast block 1, first end wall section 18, and second end wall section 20. End wall sections 18 and 20 are connected by perforated hinges 22 and 23 to sidewall section 16 and are folded inward at the hinges so that they are positioned at a 90° angle to the sidewall section. To form framework 2, folded end wall section 8 is aligned with and is positioned to overlap end wall section 18 and folded end wall section 10 is aligned with and is positioned to overlap end wall section 20. The end wall sections are secured by screws or equivalent fasteners 9.

First panel member 4 and second panel member 14 are formed of relatively lightweight, heavy duty 12/14 gauge galvanize steel.

Cross-bracing members 26, 28, and 30 have tab member connectors 32, 33, 34, 35, 36 and 37 extending from the termini of the connectors, as best seen in FIG. 2. The tab member connectors are configured to be inserted into slots 42, 43, 44, 45, 46, and 47 in sidewall sections 6 and 16 in order to secure cross-bracing members 26, 28, and 30 between the sidewall sections, as best seen in FIG. 3.

It is contemplated that various types of tab member connectors can be used. For example, connectors 32, 33, 34, 35, 36, and 37, shown in FIGS. 2-5, are twist connectors. FIG. 6 shows tab member connector 48 extending from cross-bracing member 30a, as a flat plate which is configured to be folded against sidewall sections 6 and 16 and secured in place by a fastener. FIGS. 7 and 8 show tab member connectors 50 and 52 extending from cross-bracing members 30b and 30c, having slits 54 and 56 which are designed to be inserted straight into the metal of sidewall sections 6 and 16.

Elongated bracing member 60 is positioned over cross-bracing members 26, 28, and 30 and secured thereto by screws or equivalent fasteners 9. Bracing member 60 is provided, not only to provide added strength to framework 2, but also as a support member to facilitate construction of structures which are built on ballast block 1.

Framework 2 is filled with ballast material 70, such as concrete or landfill, to form completed ballast block 1. See FIG. 4.

A significant advantage of this invention resides in the manner in which it is designed to be transported and then constructed at its end use location. All the components of ballast block framework 2 are designed to be stacked, in a disassembled state, in a compact, easy to transport, secured bundle 80. FIG. 1 shows an example of how two ballast block frameworks can be packaged in bundle 80, with ballast block framework components such as panel members 4 and 14, cross-bracing members 26, 28, and 30, elongated bracing member 60, and fastener hardware container 82. Binding straps 84, 86, and 88 tightly secure the framework components within bundle 80.

Bundle 80 is transported to the end use location of ballast block 1, where the ballast block framework components are unfastened and separated from the bundle. The various framework components are then assembled into the framework configuration previously described and shown in FIGS. 2 and 3, to form completely formed ballast block framework 2.

Framework 2 is next transported to and positioned on its exact end use location, where it is filled with ballast material 70 to form ballast block 1, ready to be used.

FIG. 9 illustrates an example of how the ballast blocks of the invention are to be utilized. Ballast blocks 1a and 1b are positioned to support solar panel racking system 90 designed to rigidly and permanently support solar panels 100.

Certain novel features and components of this invention are disclosed in detail in order to make the invention clear in at least one form thereof. However, it is to be clearly understood that the invention as disclosed is not necessarily limited to the exact form and details as disclosed, since it is apparent that various modifications and changes may be made without departing from the spirit of the invention.
