Abstract
One aspect of the invention is a bolt protection apparatus for use with a bolt inserted into an opening in a piece of lumber. The bolt protection apparatus comprises a first means for preventing at least a portion of the bolt from contacting the sidewall of the opening. The bolt protection apparatus further comprises a second means for assisting in fixing the position of a portion of the first means in the opening.
Description
- This invention relates generally to construction and more particularly to a method for building a structure, a structure, and a bolt protection apparatus for use with treated lumber.
- Treated lumber is used in various ways when building homes and other structures. In addition, treated lumber is often used for outdoor applications where ordinary lumber would otherwise be susceptible to damage or destruction by insects. For many years, treated lumber has included arsenic as one of the chemicals used to treat lumber.
- Recently, because of concerns over the potential health effects of arsenic in treated lumber, federal regulations have limited the use of arsenic. For example, treated lumber containing arsenic generally may not be used for residential applications. Because the sill plate attached to the foundation of a home is often chosen to be, or required to be, treated lumber, the regulation of lumber treated with arsenic has caused the need for new types of treated lumber to be used.
- While a new type of treated lumber has been developed, the chemicals currently proposed for use with the treated lumber are corrosive to steel and some other metals. The corrosiveness of the chemicals in new types of treated lumber presents problems for the construction industry where there is frequently pressure to reduce costs. While it is believed that stainless steel anchor bolts, nuts, washers, and other hardware may be used in construction applications using the new type of treated lumber, such hardware is much more expensive than traditional steel hardware.
- One aspect of the invention is a bolt protection apparatus for use with a bolt inserted into an opening in a piece of lumber. The bolt protection apparatus comprises a first means for preventing at least a portion of the bolt from contacting the sidewall of the opening. The bolt protection apparatus further comprises a second means for assisting in fixing the position of a portion of the first means in the opening.
- The invention has several important technical advantages. Various embodiments of the invention may have none, one, some, or all of these advantages without departing from the scope of the invention. The invention provides a cost-effective way to prevent metal bolts, washers, and/or nuts from contacting treated lumber that may contain chemicals corrosive to such bolts, washers and/or nuts. The invention may be especially useful in residential construction applications where a treated lumber sill plate may be affixed to a slab foundation, pier and beam foundation, or other type of foundation using bolts. In such an application, the invention may allow traditional steel hardware to be used for affixing the sill plate to the foundation using a bolt protection apparatus that is inexpensive and easy for construction workers to attach.
- For a more complete understanding of the present invention and the advantages thereof, reference is now made to the following descriptions taken in conjunction with the accompanying drawings in which:
-
FIG. 1 illustrates pieces of a structure that may be created in accordance with the present invention; -
FIG. 2 illustrates a portion of a structure that may be created in accordance with the present invention; and -
FIG. 3 illustrates an alternative embodiment of a protective sleeve that may be used with the present invention. - The preferred embodiment of the present invention and its advantages are best understood by referring to
FIGS. 1 through 3 of the drawings, like numerals being used for like and corresponding parts of the various drawings. -
FIG. 1 illustrates a portion of astructure 10 constructed in accordance with the invention.Structure 10 comprisesfoundation 12,anchor bolts 14,sill plate 16,protective sleeve 18,washer 22,washer 24, andnut 26. Other components may be added tostructure 10 or some of the above components omitted without departing from the scope of the invention. -
FIG. 1 illustrates one application of the use of aprotective sleeve 18 in the context of the building of a structure. Specifically,protective sleeve 18 may be used to protectanchor bolt 14 from corrosion caused by chemicals insill plate 16. Here,anchor bolts 14 are used to securesill plate 16 tofoundation 12.Foundation 12 may comprise a concrete slab, a plurality of cinder blocks, a plurality of bricks, a plurality of concrete blocks, a plurality of foam blocks, a pier and beam foundation, and/or any other type of foundation. -
Anchor bolts 14 may be affixed tofoundation 12 in any suitable manner. In this embodiment,anchor bolts 14 were inserted into foundation 12 (which is a concrete foundation) before the concrete had fully set. Similarly, in foundations that employ blocks, those blocks typically have openings therein which are filled with concrete to provide support to the foundation. Pier and beam foundations may include beams constructed from blocks or concrete forms. In any of these examples,anchor bolts 14 may be inserted intofoundation 12 before the relevant concrete has fully set. Alternatively, in some applications,anchor bolts 14 may be placed intofoundation 12 after the concrete has set. In such applications, a hole will typically be drilled infoundation 12 to insert the bolt and the bolt may be held in place, for example, using epoxy or by mechanical means. For the avoidance of doubt, the term “foundation” is meant to include basements that may be created, for example, out of cinder blocks with concrete poured into openings therein. - While in this embodiment, the
protective sleeve 18 is used withanchor bolts 14,protective sleeve 18 could be used to protect any type of bolt from corrosive chemicals used to treat a piece of lumber such assill plate 16. Moreover, bolts other thananchor bolts 14 could be used to attachsill plate 16 tofoundation 12 without departing from the scope of the invention. -
Protective sleeve 18 comprises a generally tubularfirst portion 19 which may prevent at least a portion ofanchor bolt 14 from contacting the side wall of opening 20 insill plate 16. In this embodiment, opening 20 has a generally circular shape but anyshaped opening 20 may be used without departing from the scope of the invention. The illustratedcircular opening 20 has one continuous sidewall, but openings of a different shaped cross-section may have multiple sidewalls. In this patent, the term “sidewall” is broadly intended to include all sidewalls of anyshaped opening 20 where the opening has more than one sidewall. - In this embodiment,
protective sleeve 18 further comprises asecond portion 21 which may resist movement offirst portion 19 in a direction substantially perpendicular to opening 20 whenprotective sleeve 18 is inserted through opening 20. Thus,second portion 21 may assist in fixing the position of a portion of the protective sleeve 18 (here a portion of first portion 19) in the opening 20 when theprotective sleeve 18 is inserted therein. For example,second portion 21 may resist upward movement ofprotective sleeve 18 in opening 20 when inserted as shown inFIG. 1 . As discussed below,second portion 21 may also resist downward movement relative to opening 20 especially when bonded to another object using an adhesive. In this embodiment,second portion 21 ofprotective sleeve 18 is integrally formed withfirst portion 19. However,second portion 21 may be a separate piece without departing from the scope of the invention. In addition, whensecond portion 21 ofprotective sleeve 18 is a separate piece, it could be bonded tofirst portion 19 or simply placed in contact therewith. In this embodiment,second portion 21 comprises a square washer with a width W of two inches. The inside diameter D offirst portion 19 ofprotective sleeve 18 as well as the inner diameter of an opening insecond portion 21 is one half inch. In this embodiment, the length L ofprotective sleeve 18 is three and a quarter inches. This length may be desirable for use with a 2×4 used forsill plate 16. A 2×4 is only one and one half inches thick typically.Sill plate 16 may be of any dimensions without departing from the scope of the invention. For example, 2×6's and 2×10's are sometimes used in construction applications forsill plate 16. - While specific dimensions have been provided,
protective sleeves 18 with different dimensions may also be used without departing from the scope of the invention. Whilesecond portion 21 ofprotective sleeve 18 comprises a square washer, a circular washer or any other shape of washer may be used without departing from the scope of the invention. In some embodiments,second portion 21 may be omitted fromprotective sleeve 18 and not used therewith. - In this embodiment,
first portion 19 ofprotective sleeve 18 is cylindrical with a generally circular cross section. However, whilefirst portion 19 ofprotective sleeve 18 will generally be tubular, the cross section does not necessarily need to be circular and any shaped cross section may be used without departing from the scope of the invention. - In this embodiment,
protective sleeve 18 is made of plastic but could be made of rubber or some other suitable material. Preferably,protective sleeve 18 either does not corrode due to contact with chemicals used to treatsill plate 16 or corrodes very slowly due to contact with such materials. When placed overbolt 14,protective sleeve 18 may prevent at least a portion ofbolt 14 from contacting the side wall of opening 20 insill plate 16.Protective sleeve 18 may also prevent the entire portion ofanchor bolt 14 which is surrounded by opening 20 from contacting the sidewall ofopening 20. Thus,protective sleeve 18 may retard or prevent the corrosion ofbolt 14 by preventingbolt 14 from directly contactingsill plate 16. - In this embodiment, a
washer 22 may be placed overbolt 14 andprotective sleeve 18. In some embodiments,washer 22 may rest on the top ofprotective sleeve 18.Washer 22 may be plastic, rubber, or another suitable material which either does not corrode or corrodes very slowly in response to contact with chemicals used to treatsill plate 16. Ametal washer 24 andmetal nut 26 may then be used to more tightly affixsill plate 16 tofoundation 12 usinganchor bolt 14.Washer 22 may prevent contact betweenwasher 24 and/ornut 26 andsill plate 16 to retard or prevent corrosion ofwasher 24 and/ornut 26. In some embodiments,washer 24 and/ornut 26 may be made of items other than metal. - In some embodiments, either
