Embodiments provided herein generally relate to construction, and more specifically to equipment and methods for squaring a foundation of a structure.
Squaring the foundation of a structure, wherein a construction surface is marked at the perimeter of the foundation of a structure, is a necessary step in many construction projects. For example, a construction project may require the corners of a rectangular foundation of a structure be visually marked, such as with posts. However, squaring foundations of structures can be a difficult and time consuming process.
Special tools may be required to precisely mark the position where a structure is to be built. However, these tools may not give users any concrete and discernable indication of being completely square or rectangular with 90° angles on all sides, requiring users to determine the proper position simply by their visual perception. This method may cause inaccuracies and thus, flaws in the resulting structure.
Accordingly, a need exists for a device and process to efficiently square a foundation of a structure.
In one embodiment, a footer square apparatus for squaring a foundation of a structure may comprise a footer square body, a first guide line, a second guide line, and a post receiving opening. The first guide line may be disposed on the footer square body and have a length that is substantially straight. The second guide line may be disposed on the footer square body and have a length that is substantially straight. The post receiving opening may be disposed through the footer square body and may receive a post. The length of the first guide line may be substantially perpendicular to the length of the second guide line. The post receiving opening may be located at the intersection of the first guide line and the second guide line.
In another embodiment, a system for squaring a foundation of a structure may comprise a footer square apparatus, a first string segment, a second string segment, and a post. The footer square apparatus may comprise a footer square body, a first guide line disposed on the footer square body and having a length that may be substantially straight, a second guide line disposed on the footer square body and having a length that may be substantially straight, and a post receiving opening disposed through the footer square body that may receive a post. The length of the first guide line may be substantially perpendicular to the length of the second guide line. The post receiving opening may be located at the intersection of the first guide line and the second guide line. The post may be partially inserted into a construction surface and may be positioned in a substantially vertical direction. The first string segment may be aligned with the first guide line and second string segment may be aligned with the second guide line.
These and additional features provided by the embodiments described herein will be more fully understood in view of the following detailed description, in conjunction with the drawings.
The embodiments set forth in the drawings are illustrative and exemplary in nature and not intended to limit the subject matter defined by the claims. The following detailed description of the illustrative embodiments can be understood when read in conjunction with the following drawings, where like structure is indicated with like reference numerals and in which:

Referring still to
The first guide line 30 and second guide line 31 may be substantially straight respectively. However, the first guide line 30 and second guide line 31 need not be entirely straight lines. The first guide line 30 and second guide line 31 may be any pattern or design which allows a user to align a string that is held straight with the first guide line 30 or second guide line 31. For example, the first guide line 30 or second guide line 31 could be a pattern of shapes that are aligned in a straight line. The guide line may even be a single marking, for example a marking on the first or second leg 3, which allows for a string to be properly aligned. It should be understood that a guide line as used herein need not have the physical features of a geometric line, but may be any collection of points or a pattern that allow a string to be aligned at a desired angle, such as two points.
In some embodiments, the first guide line 30 or second guide line 31 may comprise a collection of markings. In one embodiment, the first guide line 30 comprises two inner guide line markings 16,17 and two outer guide line markings 32,33, such that the inner guide line markings 16,17 are parallel lines that are parallel to the outer guide line markings 32,33. Similarly, the second guide line 31 may comprise two inner guide line markings 18,19 and two outer guide line markings 34,35, such that the inner guide line markings 18,19 are parallel lines that are parallel to the outer guide line markings 34,35. For example, the first guide line 30 may comprise a set of parallel lines 16,17,32,33. Similarly, the second guide line 31 may comprise a set of parallel lines 18,19,34,35. In one embodiment, the outer guide line markings 32,33,34,35 are raised areas on the top surface 15 of the footer square body 12. The inner guide line markings 16,17,18,19 may be contoured lines that are disposed on the raised area defined by the outer guide line markings 32,33,34,35. However, it should be understood that in some embodiments, a collection of lines need not be disposed on the footer square body 12, as a small marking or straight line may function as a first guide line 30 or second guide line 31. Additionally, in some embodiments, more than one set of outer line markers may be disposed on the footer square body 12 to form the first guide line 30 or second guide line 31.
The first guide line 30 may be perpendicular to the second guide line 31, such that a right angle is formed by the first guide line 30 and second guide line 31. In other embodiments, the first guide line 30 and second guide line 31 may be at other angles with respect to one another if a non-right angle is desired in the foundation of the structure.
The footer square body 12 may comprise a post receiving opening 40 that is disposed through the footer square body 12 and defined by a post receiving opening wall 41. The post receiving opening 40 can receive a post 50, such that the post 50 can be inserted through the post receiving opening 40, as shown in
In one embodiment, the post receiving opening 40 is positioned at the intersection of the first guide line 30 and second guide line 31. The first guide line 30 and second guide line 31 may emanate from the post receiving opening 40 and project at a right angle.
The footer square body 12 of the footer square apparatus 100 may comprise one or more string receiving openings 20,21 that pass through the footer square body 12 and are defined by string receiving opening walls 22,23. A first string receiving opening 20 may be disposed on the first guide line 30 and allow a string or other wire to pass through the footer square body 12. The first string receiving opening 20 may be positioned on the first guide line 30 at the proximal end of the first guide line. Similarly, the second string receiving opening 21 may be positioned on the second guide line 31 at the proximal end of the second guide line. The first string receiving opening 20 and the second string receiving opening 21 may be of any shape such that a string can be secured at the string receiving opening 22,23 and maintain a stationary position at the first string receiving opening 20 and second string receiving opening 21. For example, a string segment 56,57 could pass through a string receiving opening 20,21, be knotted on the underside of the footer square body 12 and be pulled taught on the top side of the footer square body 12 to the distal end of the applicable guide line.
Now referring to
The post 50 may be inserted into the construction surface, such that the length of the post 50 is substantially vertical. The post 50 is inserted into the construction surface at a corner of a rectangular foundation of a building or other structure. In one embodiment, the footer square body 12 is positioned on the post 50 at a distance above the construction surface, wherein the post 50 is disposed through the post receiving opening 40. For example, the footer square apparatus 100 can be positioned at about 6 inches, about 12 inches, about 24 inches, or even about 5 feet above the construction surface.
A first string segment 56 may be may be positioned through the first string receiving opening 20 and a second string segment 57 may be positioned through the second string receiving opening 21. The first string segment 56 is aligned with the first guide line 30 and the second string segment 57 is aligned with the second guide line 31, such that the first string segment 56 is substantially parallel to the first guide line 30 and the second string segment 57 is substantially parallel to the second guide line 31. The first string segment 56 and the second string segment 57 may be arranged such that the first string segment 56 and second string segment 57 are at a 90° angle, and such that the first string segment 56 and second string segment 57 lie on a horizontal plane. It should be understood that the string may be any suitable type of string such as a woven fabric string, rope, wire, twine, plastic string, or combinations thereof.
Still referring to
In another embodiment, the first string segment 56 and second string segment 57 may be attached to the post 50. For example, the first sting segment and the second string segment 57 may be tied to the post 50, and pulled taught in alignment with the first guide line 30 and second guide line 31 respectively.
To measure a rectangular foundation, the post 50 is inserted at a corner of the structure foundation. The first string segment 56 is pulled taught and aligned with the first guide line 30 and the second string segment 57 is pulled taught and aligned with the second guide line 31. The first string segment 56 and second string segment 57 are used as a guide for measuring a right angle and to affix a second and third marker, such as additional posts, into the construction surface at the other corners of the structure. The footer square apparatus 100 may be used on a different corner post, and the process can be repeated until a rectangular building foundation is measured. Additional measuring tools, such as a ruler or other length measuring devices, may be used to measure the distance of the corners marked by posts or other markers.
It should be understood that the footer square apparatus 100 can be positioned above the construction surface when affixed to the post 50, allowing the string to be pulled taught on a horizontal plane and not contact the construction surface. This feature allows for effective measurement of rectangle for a building foundation on uneven construction surfaces, such as hill or other downgrade.
