Abstract
A brace for a multi-section manufactured home comprising left and right sections; each section having a beam having an upper end including a lateral flange supporting a floor structure, and a medial side; the floor structures meeting at a mating seam distal from each beam, generally comprises left and right brackets joined by a steel strap, a tensioning bolt for the strap, a vertical post, and a horizontal compression member. Left and right brackets include an outer hook for beam attachment by hooking over the lateral flange of left and right beams respectively. The strap is attached to a take-up bolt on one bracket for adjusting strap tension. The post is supported by the midsection of the strap and supports the left floor structure and the right floor structure across the mating seam.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




This invention relates to a support for the marriage or mating seam of a multi-section manufactured home, mobile home, or trailer coach, and more specifically to an adjustable brace for application in situ for supporting the mating seam.




2. Description of the Related Art




The maximum width of a manufactured home is typically restricted to the maximum width allowable for common transport on public highways. Consequently, two or more manufactured home sections often are transported separately and then joined to form a wider, larger manufactured home. A larger manufactured home may be called a “multi-section”, or a “double-wide” or a “triple-wide”, as appropriate.




The floor juncture of the two sections is called a mating seam or a marriage seam. Conventionally, the floors adjacent the mating seam are only directly supported by the cantilevered ends of traverse floor joists, such that the seam is wavy and/or floors on either side of the seam do not align to form a flat surface. Of course, such results are undesirable.




A section for a multi-section manufactured home typically includes one or more longitudinal main I-beams which support a plurality of transverse floor joists which directly support the floor and the wall structure including wall studs. A plurality of spaced support piers support the main beams.




Conventionally, the mating seam has been supported, if at all, by vertical perimeter jacks disposed between the ground and the outer end of the joists. Conventional perimeter jacks have several disadvantages. For example, it is common for the support piers to settle and to settle by differing amounts such that the load on a particular perimeter pier will increase to unacceptable levels, even to failure level. Also, support piers need frequent adjustment to even the loading on the main beams. Each such adjustment requires that the perimeter jacks be adjusted also.




Therefore, there has been a need for means for supporting the mating seam of a manufactured home that overcomes the shortcomings of the prior art.




Preferably, the support means is easily applied in situ in the field.




SUMMARY OF THE INVENTION




This invention is a brace for a multi-section manufactured home; the home comprising left and right sections; each section having a beam having an upper end including a lateral flange supporting a floor structure, and a medial side; the floor structures meeting at a mating seam distal from each beam. The brace generally comprises left and right brackets joined by a steel strap, a tensioning bolt for the strap, a vertical post, and a horizontal compression member.




Left and right brackets include an outer hook for beam attachment by hooking over the lateral flange of left and right beams respectively. The strap is attached to a take-up bolt on one bracket for adjusting strap tension. The post is supported by the midsection of the strap and supports the left floor structure and the right floor structure across the mating seam.




A horizontal compression member spans between the medial side of the left section beam and the medial side of the right section beam substantially between the brackets. Preferably, the post supports the midsection of the horizontal compression member. Preferably, the right bracket is attached to the right section beam in front of the horizontal compression member, and the left bracket is attached to the left section beam in back of the horizontal compression member. A bearing on the post reduces friction during tensioning of the strap/




Other features and many attendant advantages of the invention will become more apparent upon a reading of the following detailed description together with the drawings wherein like reference numerals refer to like parts throughout.

Having described the invention, it can be seen that brace


10


provides a very desirable device for supporting the mating seam


89


of a multi-section manufactured home. Importantly, brace


10
