With continuing reference to the accompanying drawings, wherein like reference numerals designate similar parts throughout the various views, reference numeral 10 generally designates a portable building constructed in accordance with the concepts of the present invention. In the illustrative embodiment of portable building 10 there is shown a circular shaped structure. Of course, square, rectangle, polygonal or other shaped buildings may be constructed in accordance with the teachings of this invention.
The portable building structure 10 is adapted to be mounted on any suitable base or foundation 12. The foundation 12 may be constructed of poured concrete, or may be of wood and in some instances earth may be hard packed to form at least a portion of the founda tion 12.
The erecting structure for the building It) includes a plurality of anchors 14 to which posts 16 and braces 18 are pivotally connected. The posts 16 in turn are pivotally connected to beams 20. The braces 18 are pivotally connected to slide members 22 movably mounted on the I-beams 20. The I-beams 20 are pivotally interconnected by any suitable center mounting member 24. As shown in FIGS. 2 and 3, the beams 20 may be arranged in pairs, or the beams 20 may be interconnected to each other at the center of a circular building 10 as seen in FIG. 1. The beams when arranged in spaced parallel pairs can be used to form a rectangular shaped building.
Each of the anchors 14 is secured to the foundation 12 by bolts 30 or the like which extend through the base plate 32 of each anchor 14. A pair of trapezoidal shaped trunnions 34 and 36 rise upwardly from the base plate 32.
The posts 16 and the braces 18 are pivotally secured to the trunnions 34 and 36. Each post 16 includes a tubular main portion 38 and a pair of depending plates 4% and 42 which are welded or otherwise attached to the main tubular portion 38 on opposite sides thereof and which are designed so as to fit inwardly of the trunnions 34 and 36.
Each of the braces 18 have a pair of plates 44 and 46 welded or otherwise secured to the main tubular portion 48 thereof. The plates 44 and 46 are adapted to be disposed on opposite sides of the main tubular portion 48 and outwardly of the trunnions 34 and 36. A shaft 50 extends through and between the trunnions 34 and 36 and through and between the pairs of plates 40 and 42, and 44 and 46. The shaft 50 serves as the pivotal mounting means for the post 16 and braces 18 with respect to the trunnions 34 and 36 of the anchors 14.
The beam 20 is I-shaped in cross section, having a web 60, upper flanges 62 and 64, and lower flanges 66 and 68. Adjacent the outer end 70 of each beam 20, the lower flanges 66 and 68 are cut away as at 72 so that the outer end portion of the beam is substantially of a T-shape in cross section. Each beam 20 has the post 16 associated therewith pivoted thereto by means of plates 3 74 and 76 which are welded or otherwise secured on either side of the tubular portion 38 of the post. A shaft 78 extends through the straps 74 and 76 and through the web 60 to provide the pivotal mounting means for each post 16.
Slidably mounted on each beam 20 are the slide members 22. The slide members 22 are substantially channel shape in cross section, having sides 80 and 82 interconnected by a top portion 84. The sides 80 and 32 have inwardly extending flanges 86 and 88 which are adapted to underlie the flanges 66 and 68. A plurality of cross members 90, 92, 94, 96 are welded or otherwise secured to and extend between the flanges 86 and 83.
The slide 22 is movable in a sliding manner along the beam 20 by means of pairs of rollers 98, 100, and 102, etc., the other roller paired with roller 16?. not being visible in the drawings. These rollers ride on the flanges 66 and 68 and are engageable with the flanges 62 and 64 to reduce friction and to provide for the sliding action desired. The rollers 98 and 100 are mounted on axles 99 journalled on sides 80, 82 and extend toward the Web 60 while the roller 102 and its mate are mounted on axles 101. The axles 101 also are journalled on sides 80, 82 and extend toward the web 60.
Welded or otherwise secured to the sides 30 and 82 of slide member 22 are plates 104 and 106. A shaft 108 is used for pivoting the plates 104 and 166 to the tubular portion 48 of the brace 18.
Pivoted to the side walls 80 and 82 of the slide members 22 are fittings in the form of eyes 110 and 112 to which a pair of cables 114- and 116 are attached. The cables have their opposite ends attached to eye shaped fittings 118 and 120, which are secured to a connecting member 122 to which an eye fitting 124 at the end of a cable 126 is attached. The cables 114 and 116 are entrained over pulleys 130 and 132, which are rotatably mounted by means of the pin 78 which extends through the Web 60. The cable 126 is entrained over a pulley 140 mounted on the pin 50 so that the end 142 of the cable may conveniently be connected to a winch for providing the power to be used in erecting the portable building structure.
With the beams 20, slide members 22, braces 18, and posts 16 in the position as is shown in phantom lines in FIG. 3, the entire building structure may be simultaneously erected by simultaneously pulling the ends 142 of the cables through operation of a winch or winches. It is to be noted that the slide members 22 are positioned towards the inner ends of the beams away from the outer ends when the beams 20 are in their lowered position. Then, pulling upon the cable ends 142 will cause the slide members to move towards the outer ends of the beams 120, which will pivot the braces 18 with respect to the beams 20 and the anchors 14 and likewise pivoting the posts 16. This will raise the beams 20 while pivoting the beams so that the inner ends of the beams will be raised higher than the outer ends to attain the position as shown in FIG. 3 in solid lines. I
It is within the concept of the present invention to arrange any suitable roof on top of the beams 20 such as that of canvas, nylon, synthetic plastic materials, panels, or the like. Alternatively, a suitable membrane and reinforcement may be provided on which concrete may be poured or sprayed as by the Gunite process.
The slide members 22 may be locked in their erected position by transverse pins extending through aligned apertures in the slide members and in the beams. Any other suitable means may be used to lock the slide members in their erected position.
