Abstract
An adjustable support system is provided for a premanufactured building structure. Struts (65, 66) are mounted at their lower or platform ends in support clevises (45, 46), and are mounted to the joists (12, 13) of the building structure. The lower or platform end (78) of the struts can be moved horizontally with respect to the support platform (36) by rotating the adjustment nut (80) on the travel screw (55) of the support clevis. This effectively reorients the strut to a greater or smaller angle with respect to the horizontal, so that the strut bears more or less of the load of the joist and the building structure. Preferably, the rotation of the adjustment nut (80) is accomplished with a torque wrench which provides the installer with an indication of the load being assumed by the strut.
Claims24
An adjustable pier for a premanufactured building having longitudinally extending parallel support joists positioned above the ground, said adjustable pier comprising:
- a support platform for positioning beneath a joist of a building;
- at least one strut having a platform end and a joist end;
- a joist connector for connecting said joist end of the strut to a joist of a building;
- a platform connector for connecting said platform end of said strut to said support platform so that the strut slopes upwardly from said support platform to said joist connector;
- said platform connector including adjustment means for progressively moving said platform end of said strut with respect to said support platform;
- whereby said adjustable pier can be positioned beneath a building and the strut progressively moved with respect to the support platform into increased compression between the platform and the joist of the building in response to said adjustment means.
A support system for a premanufactured building having a support joist, comprising:
- a support platform including cleats for engaging the ground beneath said platform;
- a strut having a joist end and a platform end;
- a joist connector for connecting said joist end of said strut to a joist of a building;
- a platform connector for connecting said platform end of said strut to said support platform so that said strut extends at a slope upwardly from said support platform toward the joist of the building structure;
- said platform connector including force adjustment means for progressively moving said platform end of said strut with respect to said support platform;
- whereby the forces of compression applied to the strut between the support platform and the joist are progressively adjusted by progressively changing the position of the platform end of the strut with respect to the support platform.
A support system for a premanufactured building having longitudinally extending parallel support joists, said support system comprising:
- a plurality of static piers mounted in spaced relationship from one another on the ground adapted for positioning beneath the parallel joists of a premanufactured building for supporting the parallel joists from the ground;
- a plurality of adjustable piers mounted on the ground between said static piers, said adjustable piers each including a support platform for engaging the ground, a pair of struts extending at oppositely upwardly sloped angles from said support platform;
- said struts having opposed ends, including a platform end positioned adjacent said support platform and a joist end for placement adjacent the joist of the premanufactured building;
- a joist connector mounted to said joist ends of said struts for connecting said struts to a joist of the premanufactured building;
- a platform connector for connecting said platform ends of said struts to said support platform;
- and
- said platform connector including means for moving said platform end of each of said struts across said support platform and in an arc with respect to the joist of the premanufactured building to effectively change the compression load applied by the building to the struts.
An adjustable pier for a premanufactured building structure having a rectilinear horizontally extending support joist, said adjustable pier comprising:
- a support platform for placement on the ground beneath a support joist;
- a pair of struts extending at opposite upwardly sloped angles from said support platform for connection to ajoist of the building structure;
- connector means for connecting said struts to the joist;
- and
- adjustment means for progressively adjusting the vertical load applied by the building structure on said pair of struts.
