Description
CARRIER BEAM SYSTEM FOR MANUFACTURED HOUSES
FIELD OF THE INVENTION
The present invention relates to a carrier beam system, and more particularly to carrier beams for use in the support and movement of manufactured houses.
DESCRIPTION OF THE PRIOR ART
The manufacturing of completed or partially completed houses within a factory (both of which are referred to herein as "manufactured houses"), for subsequent transport to the installation location of the manufactured house, for example in a subdivision, is well~known. During this process it is necessary to support, lift and move the manufactured house, for example from the manufacturing factory to the house foundation or footing or like support system for the I 5 manufactured house.
Previously, perimeter frames have been manufactured and placed beneath the manufactured house, to support the manufactured house from the perimeter, for lifting.
Reference is made to Canadian Patent Number 2,139,622 (Biffis) describing a base member having a rectangular metal frame affixed to the underside of the manufactured house, which is attached through a series of straps and cables and another frame and then to an overhead crane capable of lifting and positioning the manufactured house.
The use of a perimeter frame requires the manufactured house designer to provide support for the manufactured house at those locations which are remate from the perimeter walls. To solve this problem, for example, long joists have been used to span the distance between the perimeter walls, and thereby support those floor locations whicl°a are remote from tlae perimeter. However, long floor joists are expensive and often less than optimal when designing a manufactured house, and the use of the perimeter frames of the prior art requires the builder to design floor plans based upon the maximum length of joists available, thereby limiting the flexibility of floor plans available to the manufactured house designer.
Page 1 of 9 SLTwIMARY OF THE INVENTION
The object of the present invention is to provide a device which permits increased flexibility in manufactured house floor plans and to provide support for the marmfactured house in those regions of the manufactured house which are remote from the perimeter wall.
Accordingly, the invention relates to a device for distributing the support provided to a manufactured home comprising a means for supporting the house, a beam for spanning at least two joists of the manufactured house, the said beam having a first contact surface adapted to be in contact with at least two joists of the manufactured house and the said beam having a second contact surface in engagement with the means for supporting the house.
The advantage of the present invention is that it provides a device which provides a more uniform support for the load of the manufactured house, permits shorter joists to be used in the manufacturing of manufactured houses, and provides for a simplified and reusable means of supporting manufactured houses when they are being moved and installed.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to Figure l, an embodiment of the carrier beams 10 of the present invention is illustrated, the carnet beams 10 being positioned underneath the manufactured house 20 to efficiently distribute and support the Load of the manufactured house 20.
As shown in Figure 3, when the house is ready for transportation, with the carrier beams positioned beneath the house, the house may then be loaded onto a suitable house transporter 5 Page 3 of 9 for subsequent transportation to the house foundation or elsewhere, depending the production and scheduling needs of the factory.
Referring to Figure 2, when a manufactured house 20 is being installed onto a foundation 40, skate beams 30 may be used to support the manufactured house 20 and carrier beams 10, and to provide a surface upon which the manufactured house 20 and carrier beams 10 may be moved into location above the foundation 40. It is preferred to have the carrier beams 10 aligned substantially perpendicular to the skate beams 30, and it is preferred, when designing a manufactured house 20, to have the joists of the manufactured house 20 a,:igned substantially perpendicularly to the carrier beams 10, to the extent this is possible, for improved weight distribution of the manufactured house 20.
In an alternative embodiment, the carrier beams 10 are temporarily attached to the underside of the house 20. The carrier beams 10 are positioned in spaced relation to one another, the spacing between the carrier beams being determined by the loading and stn~ctural characteristics of the house 20, and the required support of the house 20 at any particular location.
In the case where the floor of the house 20 is entirely on a single horizontal plane, as shown in Figure 1, the carrier beams 10 are likewise horizontally aligned, suhstantially parallel to one another, it being understood that the precise location of each carrier beam 10 will depend upon the unique characteristics of each house.
In the embodiment shown in Figure 1, the carrier beams 10 have a substantially horizontal top surface, the tap surface engaging the underside of the house and joists, and a substantially horizontal lower surface upon which the carrier beams 10 may rest when loaded with a house 20, and providing a surface from which the carrier beams L 0 and house 20 ma.y be lifted or lowered.
When single piece carrier beams 10 as shown in Figure 1 are utilized, the carrier beams 10 generally span across the bottom of the house and extend beyond the external wall of the house 20.
Page 4 of 9 When utilizing single piece carrier beams 10 as shown in Figure 1 to move and support a house, the foundation 40 of the house may require alteration to accommodate the passage of the carrier beam 10 below the top of the foundation wall when the house is being lowered onto the foundation, as the foundation wall would otherwise interfere with tlhe carrier beam's movement as the house is being lowered onto the foundation. For example, as shown in Figure 2, the foundation wall may need to be cut, or notched, or formed to a sufficient size 130 to allow the carrier beam to be lowered sufficiently as to allow the house to be placed on the top of the foundation, and to allow for the removal of the carrier beam once the house is securely positioned on the foundation 40.
In one embodiment, as an alternative to the solid single piece carrier beams illustrated in Figure l, mufti-part carrier beams 60, as shown in Figures 4, 5 and 8 may be constructed of two or more components which may be separated for easy disassembly after the house is positioned and lowered onto the foundation. As shown in Figure 5, this embodiment of the mufti-part carrier beam includes parts 62, 64 and 66.
As illustrated in Figure 6, in the case of one embodiment of the two part carrier beams 50, the combined length of the two part earner beam is long enough that it extends to within a short distance of the inside surface of bath of the foundation walls 80 and 82 at which the earner beam will be positioned. Similarly, in the case of another embodiment where three part carrier beams are used, the combined length of the three part carrier beam is long enough that it extends to within a short distance of both of the inside surfaces of the foundation walls at which the beam will be positioned.
The mufti-part carrier beams are joined securely and temporarily in a manner known to a worker skilled in the art. In one embodiment, face plates 55, as shown in Figure 5, are securely welded to those ends of the carrier beam sections which are to be joined to other carrier beam sections.
Holes are drilled in the face plates 55 to receive bolts 59, as shown in Figure 5, the holes being positioned to ensure that when the two face plates of tvcTo carrier beam sections axe in alignment with and abutting one another, the holes in the face plates are aligned to receive the bolts 59, which may then be inserted in the holes, and nuts threaded thereon Page 5 of 9 In one ernbodirnent, inverted "L" shaped ears 70, as shown in Figures 4, 5, and 6 are securely affixed, and preferably welded to those ends of the mufti-part carrier beams on which no face plate has been welded so that when a mufti-part carrier beam is assembled, it has ears 70 extending outwardly on both ends thereof. In this embodiment, the ears 70 are made of steel, having a thickness generally of between 3/4°' and 1 '/2 °', the horizontal surface measuring approximately 12 inches by 12 inches. These ears 70 effectively e~;tend the lifting length of the carrier beams, permitting the carrier beams, by means of the ears, to receive a significant portion of the load of the house through the rim joist 75 which rests upon tl~e ear, as shown in Figure 6.
Figure 8A illustrates the preferred embodiment of a mu.lti-part carriier beam 60 with beveled ends 90 and 92. Figures 8A and 8B also illustrates an alternative embodliment of the face plates 55 (in the embodiment shown in Figures 8A and 8B, the face plates are pl'.ate steel, having a thickness of greater than 3/8", with 16 holes bored therethrough, it being understood that a worker skilled in the art would be aware of alternative configurations for connecting mufti-part carrier beams) which securely and temporarily engage one carrier beam to another The face plates extend across the ends of two carrier beams, and, when the holes in the face plate-s align with holes in the carrier beams, the face plates are bolted 59 to the carrier beams, thereby securely engaging the two carrier beams to each other. Multiple face plates may be utilized as shown in Figures 8A and 8B for additional strength. Figure 9 illustrates the bevel 90 at the e:nd of the mufti-part carrier beam and support flange 150 extending from the lower flange 160 to the upper flange 170, said support flange 150 being proximate to the bevel 90.
Whether the carrier beams are of the single piece type as shown in Figure 1, or the mufti-piece types of Figures 4, 5, 6, 7, 8, 9 or 11 in one embodiment, the manufactured house 20 and carrier beams 50 are unloaded from the transporter 5 in close proximity te~ the foundation 40 and thereafter supported by skate beams 30 while the house and carrier beams are being positioned above the foundation 40. In one embodiment, when the house is properly positioned above the foundation, as shown in Figure 6, jacks 100 installed within the basement: of the house 20 may be used to raise the carrier beams and house 20 allowing the skate beams 30 to be removed, whereupon the house and carrier beams can be lowered.
Page 6 of 9 Figure 6 shows a two-part carrier beam 50 supporting a portion of a manufactured house 20 in a position directly above the foundation 40 and suitably aligned so as to allow the manufactured house to be lowered onto the foundation 40. Figure 6 shows a two part carrier beam 50 the ears 70 loaded with exterior walls 80 and 82 of a manufactured house 20. 'fhe manufactured house 20 may additionally be reinforced and supported by a channel 110 fixedly engaged to the ears 70, the channel abutting the exterior surface of the rim joist of the house for additional support. As shown in Figure 6, hydraulic or other suitable jacks 100 are positioned on the basement floor and suitably arranged to engage with and to support in order to lift or lower the two part carrier beam 50 and the manufactured house 20.
Figure 7 shows, in one embodiment, the manufactured house 20 in the louvered position, having been suitably lowered from the raised position illustrated in Figure 6, by rrzeans of hydraulic or other suitable jacks 100, until the manufactured house rests securely on the sill plate 120 (the sill plates having been suitably notched to accommodate and receive the ears 70).
Figure 10 illustrates the preferred embodiment of a mufti-part carrier beam with said beam in the lowered position, a cut in the sill plate 120 being marginally greater than t:he width of the upper flange 170 of the carrier beam 60 and ~, cut in the foundation 40 being marginally greater than the width of the vertical webbing 180 of said carrier beam 60.
As illustrated in Figure 10 and Figure i 1, the lower flange 160 of the mufti-part carrier beam 60 does not interfere with the foundation 40 when the carrier beam 60~ is in the lowered position. As illustrated in Figure 11, the manufactured house 20 has been installed upon the foundation 80, the rim joist 75 and floor joist 190 and resting upon the sill plate 120, the rim joist 75 and floor joist 190 supporting the floor material 200, and the exterior walls 110 (supported by the floor material 200) being ready for the application of exterior finishing, such as brick (which will rest on the brick ledge 220), siding or other suitable material, it being understood that the builder may alternatively apply the exterior finish in the factory, except where 1;o do so would make the house prohibitively heavy or difficult to transport or manipulate.
Page 7 of 9 In the case of the mufti-part carrier beams, once the manufactured house is securely positioned on the foundation, the components of the mufti-part carrier beam may then be disassembled one from the other at the face plates and removed in components from the basement, by the window 130, as shown in Figure 2, or in any other suitable manner. In the c<~se of the single piece carrier beam, it may be removed through the sufficiently sized cut or notch. 120, as shown in figure 2, in the foundation wall. The removed carrier beams may then be reused as needed.
It is understood that the number of carrier beams used far a particular house will depend on several factors, including, the loading bearing limits of the carrier beams, the loading and structural characteristics of the house, the size and shape of the house, and whether the underside of the house presents a flat or a multilayered surface.
The present invention has been described herein with regard to preferred embodiments. However, it will be obvious to persons skilled in the art that a number of variations and modifications can be made without departing from the scope of the invention as described herein.

When single piece carrier beams 10 as shown in Figure 1 are utilized, the carrier beams 10 generally span across the bottom of the house and extend beyond the external wall of the house 20.
Page 4 of 9 When utilizing single piece carrier beams 10 as shown in Figure 1 to move and support a house, the foundation 40 of the house may require alteration to accommodate the passage of the carrier beam 10 below the top of the foundation wall when the house is being lowered onto the foundation, as the foundation wall would otherwise interfere with tlhe carrier beam's movement as the house is being lowered onto the foundation. For example, as shown in Figure 2, the foundation wall may need to be cut, or notched, or formed to a sufficient size 130 to allow the carrier beam to be lowered sufficiently as to allow the house to be placed on the top of the foundation, and to allow for the removal of the carrier beam once the house is securely positioned on the foundation 40.
In one embodiment, as an alternative to the solid single piece carrier beams illustrated in Figure l, mufti-part carrier beams 60, as shown in Figures 4, 5 and 8 may be constructed of two or more components which may be separated for easy disassembly after the house is positioned and lowered onto the foundation. As shown in Figure 5, this embodiment of the mufti-part carrier beam includes parts 62, 64 and 66.
As illustrated in Figure 6, in the case of one embodiment of the two part carrier beams 50, the combined length of the two part earner beam is long enough that it extends to within a short distance of the inside surface of bath of the foundation walls 80 and 82 at which the earner beam will be positioned. Similarly, in the case of another embodiment where three part carrier beams are used, the combined length of the three part carrier beam is long enough that it extends to within a short distance of both of the inside surfaces of the foundation walls at which the beam will be positioned.
The mufti-part carrier beams are joined securely and temporarily in a manner known to a worker skilled in the art. In one embodiment, face plates 55, as shown in Figure 5, are securely welded to those ends of the carrier beam sections which are to be joined to other carrier beam sections.
Holes are drilled in the face plates 55 to receive bolts 59, as shown in Figure 5, the holes being positioned to ensure that when the two face plates of tvcTo carrier beam sections axe in alignment with and abutting one another, the holes in the face plates are aligned to receive the bolts 59, which may then be inserted in the holes, and nuts threaded thereon Page 5 of 9 In one ernbodirnent, inverted "L" shaped ears 70, as shown in Figures 4, 5, and 6 are securely affixed, and preferably welded to those ends of the mufti-part carrier beams on which no face plate has been welded so that when a mufti-part carrier beam is assembled, it has ears 70 extending outwardly on both ends thereof. In this embodiment, the ears 70 are made of steel, having a thickness generally of between 3/4°' and 1 '/2 °', the horizontal surface measuring approximately 12 inches by 12 inches. These ears 70 effectively e~;tend the lifting length of the carrier beams, permitting the carrier beams, by means of the ears, to receive a significant portion of the load of the house through the rim joist 75 which rests upon tl~e ear, as shown in Figure 6.
Figure 8A illustrates the preferred embodiment of a mu.lti-part carriier beam 60 with beveled ends 90 and 92. Figures 8A and 8B also illustrates an alternative embodliment of the face plates 55 (in the embodiment shown in Figures 8A and 8B, the face plates are pl'.ate steel, having a thickness of greater than 3/8", with 16 holes bored therethrough, it being understood that a worker skilled in the art would be aware of alternative configurations for connecting mufti-part carrier beams) which securely and temporarily engage one carrier beam to another The face plates extend across the ends of two carrier beams, and, when the holes in the face plate-s align with holes in the carrier beams, the face plates are bolted 59 to the carrier beams, thereby securely engaging the two carrier beams to each other. Multiple face plates may be utilized as shown in Figures 8A and 8B for additional strength. Figure 9 illustrates the bevel 90 at the e:nd of the mufti-part carrier beam and support flange 150 extending from the lower flange 160 to the upper flange 170, said support flange 150 being proximate to the bevel 90.
Whether the carrier beams are of the single piece type as shown in Figure 1, or the mufti-piece types of Figures 4, 5, 6, 7, 8, 9 or 11 in one embodiment, the manufactured house 20 and carrier beams 50 are unloaded from the transporter 5 in close proximity te~ the foundation 40 and thereafter supported by skate beams 30 while the house and carrier beams are being positioned above the foundation 40. In one embodiment, when the house is properly positioned above the foundation, as shown in Figure 6, jacks 100 installed within the basement: of the house 20 may be used to raise the carrier beams and house 20 allowing the skate beams 30 to be removed, whereupon the house and carrier beams can be lowered.
Page 6 of 9 Figure 6 shows a two-part carrier beam 50 supporting a portion of a manufactured house 20 in a position directly above the foundation 40 and suitably aligned so as to allow the manufactured house to be lowered onto the foundation 40. Figure 6 shows a two part carrier beam 50 the ears 70 loaded with exterior walls 80 and 82 of a manufactured house 20. 'fhe manufactured house 20 may additionally be reinforced and supported by a channel 110 fixedly engaged to the ears 70, the channel abutting the exterior surface of the rim joist of the house for additional support. As shown in Figure 6, hydraulic or other suitable jacks 100 are positioned on the basement floor and suitably arranged to engage with and to support in order to lift or lower the two part carrier beam 50 and the manufactured house 20.
Figure 7 shows, in one embodiment, the manufactured house 20 in the louvered position, having been suitably lowered from the raised position illustrated in Figure 6, by rrzeans of hydraulic or other suitable jacks 100, until the manufactured house rests securely on the sill plate 120 (the sill plates having been suitably notched to accommodate and receive the ears 70).
Figure 10 illustrates the preferred embodiment of a mufti-part carrier beam with said beam in the lowered position, a cut in the sill plate 120 being marginally greater than t:he width of the upper flange 170 of the carrier beam 60 and ~, cut in the foundation 40 being marginally greater than the width of the vertical webbing 180 of said carrier beam 60.
As illustrated in Figure 10 and Figure i 1, the lower flange 160 of the mufti-part carrier beam 60 does not interfere with the foundation 40 when the carrier beam 60~ is in the lowered position. As illustrated in Figure 11, the manufactured house 20 has been installed upon the foundation 80, the rim joist 75 and floor joist 190 and resting upon the sill plate 120, the rim joist 75 and floor joist 190 supporting the floor material 200, and the exterior walls 110 (supported by the floor material 200) being ready for the application of exterior finishing, such as brick (which will rest on the brick ledge 220), siding or other suitable material, it being understood that the builder may alternatively apply the exterior finish in the factory, except where 1;o do so would make the house prohibitively heavy or difficult to transport or manipulate.
Page 7 of 9 In the case of the mufti-part carrier beams, once the manufactured house is securely positioned on the foundation, the components of the mufti-part carrier beam may then be disassembled one from the other at the face plates and removed in components from the basement, by the window 130, as shown in Figure 2, or in any other suitable manner. In the c<~se of the single piece carrier beam, it may be removed through the sufficiently sized cut or notch. 120, as shown in figure 2, in the foundation wall. The removed carrier beams may then be reused as needed.
It is understood that the number of carrier beams used far a particular house will depend on several factors, including, the loading bearing limits of the carrier beams, the loading and structural characteristics of the house, the size and shape of the house, and whether the underside of the house presents a flat or a multilayered surface.
The present invention has been described herein with regard to preferred embodiments. However, it will be obvious to persons skilled in the art that a number of variations and modifications can be made without departing from the scope of the invention as described herein.
