30


A is tightened by turning it in the clockwise direction (from the bottom view) until it reaches the position shown as


30


B in FIG.


11


. As the floor locking nut


30


A is turned in the clockwise direction, it guides the movement of the protrusion


60


up the inclined surfaces


46


to reach the raised surfaces


48


until the protrusion


60


abuts the projections


50


, thereby pushing the protrusion


60


downward and locking it in place. Because the floor locking nuts


30


are disposed under the floor pieces


11


and bay floor


25


, it is not convenient to reach under the floor to tighten the floor locking nuts


30


. As shown in

FIG. 12

, for each floor locking nut


30


a side access or cutout


64


is conveniently provided in the corner post


12

, or bay


24


to allow access to the serrated edge


42


of the floor locking nut


30


from the outside. The floor locking nut


30


can be tightened from the outside through the side access


64


by using a flat object, such as a blade or a flat-head screw driver


66


, to push against the serrated outer edge


42


of the nut


30


to turn the nut


30


in the counter-clockwise direction (viewed from the top). The teeth of the serrated edge


42


are desirably angled or slanted to facilitate the engagement of the tool


66


with the teeth to turn the nut


30


in the proper direction. The four corner posts


12


and the lower wall


68


of the bay


24


are installed by locking them in place to the floor pieces


11


and bay floor


25


using the floor locking nuts

, threaded bolts


80


are inserted through threaded apertures of the upward projection


70


and corresponding apertured portions


76


. The bolts


80


each include a relative large wing


82


at the head which can be conveniently turned by the fingers of a user's hand without any tools. The bolts


80


are desirably made of a plastic material. Similar bolts are used to attached other components of the shed


10


. For instance, bolts


84


, which may be the same as the bolts


80


, are used to attach the lower wall


68


and upper wall


74


of the bay


24


to the corner post


12


via threaded apertures provided along the edges of these structural components, as shown in FIG.


15


.




In

FIG. 16

, the bay roof


28


is installed over the wall of the bay


24


. The connection between the bay roof


28


and the upper wall


74


of the bay


24


is secured using bolts


88


, as seen in FIG.


17


. The bolts


88


may be the same as the plastic bolts


80


, which extend through threaded apertures provided along the top edge of the upper wall


74


and the side edge of the bay roof


28


.




The remaining structural supports to be installed are the center posts


13


and braces


14


. In the embodiment shown, each brace


14


is installed first by inserting at least one bottom projection


90


into a groove or slot


92


provided in the floor pieces


11


, as shown in FIG.


18


. The bottom projection


90


may be shaped as a hook to be slid under the floor to provide a more secure connection and stable support for the brace


14


. In

FIG. 19

, the center post


13


is installed by inserting bottom protrusions


96


each through the elongated opening


40


of the nut receiving seat


36


of the floor and the elongated aperture


44


of the corresponding floor locking nut


30


, and locked by turning the floor locking nut


30


, in a manner similar to that shown in

FIGS. 10-12

. Each center post


13


and the corresponding brace


14


may be further secured together, for instance, by fasteners or the like. In one embodiment, the brace


14


includes three side bumps


98


distributed along its edge facing the center post


13


, which includes three corresponding indents aligned for receiving the side bumps


98


to be interlocked therewith, as schematically shown in FIG.

includes a spring preloaded to a slight bow shape. As best seen in

FIG. 21

, the lower roof truss


100


includes an elongated aperture


102


near each end for coupling with a boss


104


provided on top of the corresponding brace


14


. The elongated aperture


102


has an enlarged portion


106


which is sized to allow the boss


104


to pass therethrough. The narrow neck of the boss


104


then slides to a narrow portion


108


of the elongated aperture


102


under the force of the spring preload on the lower roof truss


100


so as to lock the lower roof truss


100


in place with the braces


14


. The spring preload thus provides self-locking of the lower roof truss


100


to the braces


14


, and pulls the top of the braces


14


inward.




The skylights


22


may be installed before or after the installing the roof panels

20


. If the roof panel


20


has been installed on the shed


10


first, the skylight


22


can be inserted through the opening


114


from below and then dropped into position to align the feet


110


with the slots


112


to allow the feet


110


to be snapped into the slots


112


. Advantageously, this can be done easily and quickly without any tools. Of course, different ways of mounting the skylights


22


to the roof panels


20


may be used in other embodiments.




In

FIG. 23

, the roof panels


20


are placed over the corner posts


12
