Tightening the nuts on the first end of the fastening device, will secure the fastening device to the at least one floor joist and tightening a second nut that is threadably engaged with the second end of the fastening member can pull the at least one joist towards the rigid member. The fastening device can be a threaded rod that is bent at a ninety degree angle.
Description
- The present disclosure is generally related to systems and arrangement for leveling a floor and to systems and arrangements for leveling a floor built from joists.
- Lumber that is utilized in the construction of buildings is often of poor quality. The lumber may have imperfections such as a bow, a cup, or a twist. This makes building level floors and plumb walls difficult. Further, lumber may be near perfect when “wet” and tied in a bundle or a bunk but once released from the bunk the imperfections in the board will often manifest at a later date, possibly after construction is complete. This leads to floors and walls that are bowed. Thus, boards may be straight when installed during fabrication of a wall, but heat, moisture and other forces such as loading forces may cause the boards to bow cup or twist, distorting them from their desired form and bowing a wall or floor. Such imperfect boards can cause an unsightly bow in a floor or a wall. In some cases a floor or a wall can have a bow that makes the floor or wall structurally weak, or unstable and dangerous and in other cases a floor or wall that becomes bowed can seriously detracting from the value of the house. Accordingly, there is a need for an improved system and method of straitening or leveling bowed floors and walls.

FIG. 1 is an orthogonal view of a floor joist leveler; and -
FIG. 2 is a cross sectional view of a floor joist leveler installed under a floor. - The following is a detailed description of novel embodiments depicted in the accompanying drawings. The embodiments are in such detail as to clearly communicate the subject matter. However, the amount of detail offered is not intended to limit anticipated variations of the described embodiments, but on the contrary, the claims and detailed description are to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present teachings as defined by the appended claims. The detailed descriptions below are designed to make such embodiments understandable to a person having ordinary skill in the art.
- Generally, methods and arrangements for leveling a floor are provided herein. While specific embodiments will be described below with reference to particular configuration, those of skill in the art will realize that embodiments may advantageously be implemented with other configurations.
- An apparatus for leveling a floor is disclosed that has a rigid member sized to span at least three floor joists but possibly numerous floor joists. The rigid member can have holes spaced according to spacing of the floor joists. A fastening device can be inserted into the holes of the rigid member and into holes in the floor joist and a threaded first end and a threaded second end of the fastening device can receive nuts and washers. Tightening the nuts on the first end of the fastening device, will secure the fastening device to the at least one floor joist and tightening a second nut that is threadably engaged with the second end of the fastening member can pull at least one joist towards the rigid member. The fastening device can be a threaded rod that is bent at a ninety degree angle.
- Referring to
FIG. 1 afloor leveling system 100 is illustrated. The floor leveling system can includerigid member 102, fasteningmembers nuts washers Rigid member 102 could be an angle iron, a flat plate that is bent, or an I beam. Therigid member 102 can be designed such that it can support a load of thousands of pounds while pulling a joist down to the same level of as adjacent juices. Thus, therigid member 102 should be sufficiently rigid such that it can pull down a joist that bows higher than the adjacent joists without significant flexure, deformation or distortion. In one embodiment, the rigid member can be an angle iron that measures three inches by three inches that is three sixteenths of an inch thick. - Fastening members, such as fastening
member 120 can be a threaded member that can be fastened to afloor joist 116 at a first end, vianut 118. In a specific embodiment, a hole (not shown) can be drilled through thefastening member 120 and a pin such as a dowel pin can be placed in the drilled hole to secure the fasteningmember 120 from “slipping” out of thejoist 116 similar to theway nut 118 prevents the fasteningmember 120 from slipping out of thejoist 116. Ahole 122 can be drilled in thejoist 116 and the fasteningmember 120 can be inserted into thehole 122 andnut 118 andwasher 119 can secure the first end of the threadedmember 120 to thejoist 116. A second end of thefastening member 120 can be inserted intohole 114 and anut 126 and awasher 124 can secure the second end of thefastening member 120 to therigid member 102. - When
nut 126 on the second end of the fasteningmember 120 is tightened,floor joist 116 can be pulled down towards the fasteningmember 104 into a position proximate to therigid member 102 such that the bottom of thefloor joist 116 is on, or close to the same plane as bottom of adjacent joists, thus taking a bow out of a sub floor that can lie above thejoist 116. The rigid member can be sized such that it spans more than two or at least three floor joists but possibly numerous floor joists. It has been determined that spanning four floor joists provides a substantial span and substantial strength for leveling particular floor areas as desired. Spanning less that four joists with therigid member 102 can provide less that desirable results. - Fastening
member 104 can be a threaded rod that is bent to an angle close to ninety degrees. In one embodiment the fasteningmember 120 could be a threaded rod cut to length and bent. Alternately, a solid rod could be threaded on each end and bent to the desired angle. - Referring to
FIG. 2 , arigid member 202 is illustrated wherein therigid member 202 has been placed perpendicular tofloor joists 204. As can be appreciated, some of thefloor joists 204 are at different levels causing soft spots and possibly a bow insub-floor 206. In an effort to “stiffen” andlevel sub-floor 206, a fastener such asfastener member 208 can be inserted into a hole inrigid member 202 and into a hole infloor joist 214, and washers andnuts member 208.Nut 212 can be tightened such that the fasteningmember 208 becomes secured to thejoist 214. - Then, the
second nut 210 can be installed onto the threadedmember 208 and can be can be tightened such that the fasteningmember 208 pulls thejoist 214 downward towards therigid member 202 such that thejoist 214 can become flush with therigid member 202. When the bottom edge of thejoist 208 comes into contact with therigid member 202 then the user can adjust the level of the next joist. - Depending on the bow of the
joists 204, the rigid member may pull a joist up that is hanging lower than the surrounding joists. In another embodiment, therigid member 202 andfasteners 208 can be utilized on a wall to plumb studs in a wall. In yet another embodiment the rigid member could be utilized on ceiling joists and on rafters to correct deformities in the ceiling roof or walls. The holes in therigid member 202 can be spaced according to normal floor joist spacing typically 16 and 24 inch spacing such that the fastening members can be placed proximate to, and substantially parallel with the face of thejoists 204. - The above disclosed subject matter is to be considered illustrative, and not restrictive, and the appended claims are intended to cover all such modifications, enhancements, and other embodiments which fall within the true spirit and scope of the present invention. Thus, to the maximum extent allowed by law, the scope of the present invention is to be determined by the broadest permissible interpretation of the following claims and their equivalents, and shall not be restricted or limited by the foregoing detailed description.
