Referring to FIG. 1, an exemplary modular building is illustrated in the form of a shed 100. In alternate examples, a modular building may be another type of building, such as a garage, a storage box, or a home. The shed 100 includes four walls 102, including a front wall 102a, an opposed rear wall 102b, a first side wall 102c, and an opposed second side wall 102d. The front wall 102 includes a door 104. The shed further includes a roof 106.

In some examples, a shed may include an alternate number of walls, an alternate configuration or number of doors, and may optionally further include one or more windows.

Referring still to FIG. 1, each wall 102 includes a plurality of panels 108, which are connected together to form the walls 102. Further, the roof 106 includes a plurality of panels 108, which are connected together to form the roof 106.

Referring to FIG. 2A, the panels 108 of the walls 102 and the panels 108 of the roof 106 are each extruded lineals, and extend along an extrusion axis 110. The panels 108 may be extruded from a plastic, such as vinyl. Referring to FIG. 3A, in the example shown, the panels 108 of the walls 102 and the panels 108 of the roof 106 all have a common extrusion profile 112. In some examples the panels of the wall may have a different extrusion profile than the panels of the roof. In some examples, the walls may be assembled from wall panels, and the roof may be assembled from roof panels that may be the same as, or distinct from, the wall panels.

Each panel 108 (as viewed in cross section) includes a front wall 114 which defines a front plane 116 of the panel 108, and an opposed rear wall 118 which defines a rear plane 120 of the panel 108. A first side wall 122 and an opposed second side wall 124 extend between the front wall 114 and rear wall 118. A first panel connector 126 extends from the first side wall 122 for connecting the panel 108 to a first adjacent panel 108a, as shown in FIGS. 3A and 3B. A second panel connector 128 extends from the second side wall 124 for connecting the panel 108 to a second adjacent panel (not shown).

Referring still to FIG. 3A the first 122 and second 124 panel connectors 126, 128 each comprise a hook 130. Particularly, in the example shown, the first 126 and second 128 panel connectors each comprise a single hook 130. The hook 130 of the first panel connector 126 (also referred to herein as “the first hook 130”) is engageable with a hook 130a of the first adjacent panel 108a, to connect the panel 108 to the first adjacent panel 108a, as shown in FIG. 3B. Similarly, the hook 130 of the second panel connector 128 (also referred to herein as “the second hook 130”) is engageable with a hook of the second adjacent panel to connect the panel 108 to the second adjacent panel (not shown).

The first hook 130 includes a first base 132 extending from the first side wall 122 and generally parallel to the front wall 114. The first base 132 includes a first base outer wall 144 that is coplanar with the front wall 114, and an opposed first base inner wall 146. The first hook 130 further includes a first tongue 134 extending generally perpendicular to the first base 132 and spaced from the first side wall 122. The first tongue includes a first tongue outer wall 148 extending from the first base outer wall 144 towards the rear plane 120, and a first tongue inner wall 150 extending from the first base inner wall 146 towards the rear plane 120. The first tongue 134, first base 132, and first side wall 122 define a first channel 136, which has a first opening 152 facing towards the rear plane 120. The first channel has a first depth 168, extending parallel to the first side wall 122.

Similarly, the second hook 130 includes a second base 138 extending from the second side wall 124 and generally parallel to the rear wall 118. The second base 138 includes a second base outer wall 154 that is coplanar with the rear wall 118, and an opposed second base inner wall 156. The second hook 130 further includes a second tongue 140 extending generally perpendicular to the second base 138 and spaced from the second side wall 124. The second tongue 140 includes a second tongue outer wall 158 extending from the second base outer wall 146 towards the front plane 116, and a second tongue inner wall 160 extending from the second base inner wall 156 towards the front plane 116. The second tongue 140, second base 138, and second side wall 124 define a second channel 142, which has a second opening 162 facing towards the front plane 116. The second channel has a second depth 170 extending parallel to the second sidewall 124.

With reference to FIGS. 3A and 3B, the first tongue 134 is receivable in a second channel (not shown) of the first adjacent panel 108a, and the first channel 136 receives a second tongue 140a of the first adjacent panel 108a, to connect the first adjacent panel 108a to the panel 108. Similarly, the second tongue 140 is receivable in a first channel of the second adjacent panel (not shown), and the second channel 142 receives a first tongue of the second adjacent panel (not shown), to connect the second adjacent panel to the panel 108.

The first tongue inner wall 150 may comprise a first catch 164, and the second tongue inner wall may comprise a second catch 166. Referring to FIG. 3B, the first catch 164 is engageable with a second catch 166a of the first adjacent panel 108a, to aid in securing the first tongue 134 in the second channel of the first adjacent panel 108a. The second catch 166 is engageable with a first catch of the second adjacent panel (not shown), to facilitate securing the second tongue 140 in the first channel of the second adjacent panel (not shown).

In the example shown, the first catch 164 and second catch 166 are substantially identical. The first catch 164 includes a first protrusion extending towards the first sidewall 122, and the second catch 166 includes a second protrusion extending towards the second sidewall 124. Referring to FIG. 3B, the first protrusion is engageable with a second protrusion of the first adjacent panel 108a, and the second protrusion is engageable a first protrusion of the second adjacent panel (not shown).

In alternate examples, a first catch and second catch may not be identical, and may be of different configurations. For example, a first catch may include a first protrusion extending towards a first side wall, and a second catch may include a second recess (not shown). The protrusion may be receivable in a recess of the first adjacent panel, and the recess may receive a protrusion of the second adjacent panel.

Referring to FIGS. 4A and 4B, in a further alternate example, where like reference numerals are used to refer to like features of FIG. 3A with the first digit incremented to 4, the first 426 and second 428 panel connectors may not include a catch.

Referring back to FIG. 3A, in the example shown, the first depth 168 and the second depth 170 are substantially equal, and the first tongue 134 is sized to substantially fill a second channel (not shown) of the first adjacent panel 108a, and the second tongue 140 is sized to substantially fill a first channel of the second adjacent panel (not shown). In other words, when assembled, the leading edge of the tongue generally abuts the base of the connector when the walls 114, 118 of one panel 108 are coplanar with the walls 114a, 118a of an adjacent panel 108a connected thereto.

In an alternate example, shown in FIGS. 5A and 5B where like reference numerals are used to refer to like features of FIG. 3A with the first digit incremented to 5, the second depth 570 is greater than the first depth 568 of the connectors 528, 526 of the panel 508. The first tongue 534 extends only partially along the depth 570a of the second channel 542a of the adjacent panel 508a. This can leave a gap 571 or drainage trough that can facilitate draining away water that may work its way between the connectors of adjacent panels. When used to make a roof (such as roof 106 shown in FIG. 1), the panels 508, 508a can be oriented so that the second, deeper channels 542 open upwards (as shown in FIGS. 5A and 5B). This can help to prevent water from collecting in the connector portions (potentially leading to mold or other problems) and/or from leaking through the roof into the shed interior.

In the assembled panels 508, 508a of FIG. 5B, the second tongue 540a of the adjacent panel 508 does substantially fill the first channel 534 of the panel 508. The leading edge of the tongue 540a generally abuts the base 532 of the connector 526 when the walls 114, 118 of one panel 108 are coplanar with the walls 114a, 118a of an adjacent panel connected thereto. In this way, at each joint between adjacent panels, an abutment surface is provided to help align the adjacent panels in coplanar relationship when assembled, and a drainage trough is provided to facilitate moisture management.

In a further alternate example, shown in FIGS. 6A and 6B, where like reference numerals are used to refer to like features of FIG. 3A, with the first digit incremented to 6, the first depth 668 is substantially the same as the second depth 670, and is greater than the depth of the tongues received therein. When the panel 608 is connected to the first adjacent panel 608a, the first tongue 640 does not substantially fill the second channel of the first adjacent panel 608a, and the second tongue 640a of the first adjacent panel 608a does not substantially fill the first channel of the panel 608 (i.e. the tongues 640, 640a extend only partially into the depths of the corresponding channels). Furthermore, the second tongue 640 would not substantially fill a first channel of the second adjacent panel (not shown), and the first tongue of the second adjacent panel (not shown) would not substantially fill the second channel 642 of the panel 608.

In some examples where a tongue does not substantially fill a channel (i.e. where a gap such as gap 571 is provided between the leading edge of a tongue and the bottom of the channel into which the tongue is installed), a reinforcing bar (not shown) may optionally be inserted into one or more gaps to provide reinforcement to the respective joints. Alternately, a reinforcing bar may be inserted into one of the first tongue and the second tongue, to provide reinforcement to the joint. For example, referring to FIG. 5C, a reinforcement bar 572 is inserted into the second tongue 540.

Referring back to FIG. 3A, each panel 108 has a front width 180, and a rear width 182, each of which extends perpendicular to the extrusion axis 110. The front width 180 is defined by the front wall 114, and the first base outer wall 144. The rear width 182 is defined by the rear wall 118 and the second base outer wall 154. The front width 180 and rear width 182 are substantially equal, but are offset from each other in a direction perpendicular to the extrusion axis 110. The offset distance 184 is generally equal to a width 186 of both the first hook 130, and the second hook 130 (also referred to herein as a hook width 186).

When assembling the shed 100, a foundation may first be poured, and a base 174 (shown in FIG. 1) may be secured to the foundation. The base may include a plurality of aluminum tracks arranged to align with the four walls 102a to 102d, the tracks having an upwardly open recess to receive lower ends of the panels 108. The panels 108 may then be assembled to the base 174, and to each other. In order to assemble the panels 108 to the base, the panels may be lowered into the track recess.

The panels may be assembled to each other either by sliding engagement in a direction parallel to the axis 110, or by sliding engagement perpendicular to the axis. For example, two panels 108, 108a may be assembled by aligning the lower end of a first connector 126 with the upper end of a second connector 128a of an adjacent panel 108a, and then sliding the panels together in a lengthwise direction. Alternatively, two panels may connected together by aligning all or most of the length of the tongue of one connecter with the opening of the channel in the connector of an adjacent panel, and then sliding (or pushing) the tongue into the channel. A combination of these two assembly techniques can be used, for example, by pushing (in the perpendicular direction) a portion of the tongue into the channel of an adjacent panel, and then sliding the panels relative to each other in a lengthwise direction to complete the assembly.

Referring to FIGS. 7 and 8, a plurality of panels 108 may be connected together to form the walls 102. The panels may have different heights, and may be assembled in a particular configuration, so that the front wall 102a and rear wall 102b are gabled. A corner piece 176 may be used to connect two or more walls 102 together at a corner.

An alternate corner piece 576 is shown in FIG. 5D. The corner piece 576 is usable with the panels 508 shown in FIGS. 5A to 5C.

Referring now to FIGS. 9A and 9B, a tie 900 is shown. As will be described further below the tie 900 can facilitate attaching a panel 108 of the roof 106 to one of the side walls 102c, 102d. Further, the tie 900 may cover the upper end 103c, 103d, respectively, of the side walls 102c, 102d, and the outer ends of the panels 108 of the roof 106.

The tie 900 is, in the example illustrated, an extruded lineal that extends along a tie extrusion axis 901. The tie 900 may be extruded from a plastic, such as a vinyl, for example. In the example illustrated, the tie 900 is formed of an aluminum extrusion. The tie 900 includes a top portion 902 and a bottom portion 904. The top portion 902 includes a roof panel outer end channel 906 for receiving an outer end portion of a roof panel 108. The roof panel outer end channel 906 is defined by a tie lower wall 908, a tie upper wall 910 spaced above the tie lower wall 908, and a tie end wall 912 extending between the tie lower wall 908 and tie upper wall at an outer end 914 of the top portion. The tie upper wall 910 has a tie upper wall width 916 and tie lower wall 908 has a tie lower wall width 918, and the tie lower wall width 918 is greater than the tie upper wall width 916.

Referring still to FIGS. 9A and 9B, the bottom portion 904 of the tie 900 includes a wall channel 920 for receiving an upper end of a side wall 102c, 102d. The wall channel 920 is defined by a tie inner wall 922 extending downwardly from the tie lower wall 908, and a laterally spaced tie outer wall 924 extending downwardly from the tie lower wall 908.

The connector upper wall 1022 and connector lower wall 1026 can define a roof panel inner end seat 1018 in the form of a channel, and the connector upper wall 1024 and connector lower wall 1028 can define a roof panel inner end seat 1020 in the form of a channel.

The connector lower walls 1026, 1028 each comprise a first section 1030, 1032, respectively, adjacent the central section 1004, and a second section 1034, 1036, respectively, extending from the first section 10301032. The first sections 1030, 1032 each have a first wall thickness (not shown), and the second sections 1034, 1036 each have a second wall thickness (not shown), and the first wall thickness is greater than the second wall thickness. The ridge beam 1000 further includes a first bracing wall 1038 extending between the first section 1030 of connector lower wall 1026 and the first side 1010 of the central section 1004, and a second bracing wall 1040 extending between the first section 1032 of the connector lower wall 1028 and the second side 1012 of the central section 1004.

Referring still to FIG. 10, the ridge beam 1000 may be an extruded lineal, and the central section 1004 may be integrally formed with the first 1014 and second 1016 roof panel connectors. That is, the load bearing central section 1004 and the connector upper walls 1022, 1024 and lower walls 1026, 1028 may be integral, unitary portions of a single extruded lineal. The ridge beam 1000 may be a metal, such as aluminum.

Referring now to FIG. 11A, in order to assemble the roof 106 to the walls 102 of the shed, a ridge beam 1000 may be assembled to the front 102a and rear 102b walls (not shown in FIG. 11A) of the shed 100. For example, the front 102a and rear 102b walls may include cutouts (not shown) in which the ends of the ridge beam 1000 are received so that the ridge beam 1000 is supported by the front 102a and rear 102b walls.

A first tie 900a may be assembled to the first side wall 102c, and a second tie 900b may be assembled to the second side wall 102d, so that the first 900a and second 900b ties extend parallel to the ridge beam axis 1002 (shown in FIG. 10). Specifically, the upper end 103c of the first side wall 102a may be inserted into a wall channel 920 (shown in FIGS. 9A and 913) of the first tie 900a until the upper end 103c of the first side wall 102c abuts a tie central wall 926 of the wall channel 920, and the upper end 103d of the second side wall 102d may be inserted into the wall channel 920 (shown in FIGS. 9A and 9B) of the second tie 900b until the upper end 103d abuts a tie central wall 926 of the wall channel 920.

Referring still to FIG. 11A, a plurality of panels 108 may be assembled to the ridge beam 1000, first tie 900a, and second tie 900b. For simplicity, the following description relates to the assembly of two panels 108 to the ridge beam 1000, first tie 900a, and second tie 900b, so that one panel 108 is on each side of the ridge beam 1000. However, if more than two panels 108 are to be assembled to the ridge beam 1000, first tie 900a, and second tie 900b, the panels 108 may first be assembled together, as described above with respect to FIGS. 2A to 3B, and the assembled panels 108 may be assembled to the ride beam 1000, first tie 900a, and second tie 900b, in the same manner as will be described below. For example, five panels 108 may be assembled together, and then assembled to the ridge beam 1000 and first tie 900a as described below. Another five panels 108 may be assembled together, and then assembled to the ridge beam 1000 and second tie 900b as described below.

As will be described in more detail below, a first panel 108c may be assembled to the ridge beam 1000 such that (1) the first panel 108c extends transversely to the ridge beam axis 1002 (shown in FIG. 10) and downwardly and outwardly from the ridge beam 1000, (2) an inner end portion 105c of the first panel 108c is engaged by the first panel connector 1014, and (3) an outer end portion 107c of the first panel 108c is engaged by the roof panel outer end channel 906a of the first tie 900a. A second panel 108d may be assembled to the ridge beam 1000 such that (1) the second panel 108d extends transversely to the ridge beam axis 1002 and downwardly and outwardly from the ridge beam 1000, (2) an inner end portion 105d of the second panel 108d is engaged by the second panel connector 1016, and (3) an outer end portion 107d of the second panel 108d is engaged by the roof panel outer end channel 906b of the second tie 900b.

To assemble a first panel 108c to the ridge beam 1000 and first tie 900a, the first panel 108c may be positioned on top of the first tie 900a, and the inner end portion 105c of the first panel 108c may be slid towards and into the roof panel inner end channel 1018. The roof panel has a first panel length 109 (shown in FIGS. 2A and 11C), and a first panel spacing 111 (shown in FIG. 11C) extends orthogonally between the first side 1010 of the central section 1004 of the ridge beam and the tie end wall 912a. The first panel length 109 is less than the first panel spacing 111. Specifically, the first panel length is less than the first panel spacing 111 by an insertion gap 113 that is greater than the tie upper wall width 916 (shown in FIG. 9A) of the first tie 900a. Accordingly, referring to FIG. 11B, as the inner end portion 105c is slid into the roof panel inner end channel 1018 (not labeled in FIG. 11B), the outer end 107c of the first panel 108c will slide over and past the tie upper wall 910a. Referring to FIG. 11C, the outer end portion 107c of the first panel 108c may then be lowered such that it rests on the tie lower wall 918a, and the first panel 108c may be slid outwardly, such that the outer end portion 107c is received in the roof panel outer end channel 906 (not labeled in FIG. 11C) of the first tie 900a. When the outer end portion 107c is received in the roof panel outer end channel 906, the inner end portion 105c is spaced from the first side 1010 of the central section 1004.

The second panel 108c may be assembled to the ridge beam 1000 and second tie 900b in a similar manner.

Referring still to FIG. 11C, in the assembled roof 106, the cavity 1011 (shown in FIG. 10) of the ridge beam 1000 may be substantially empty, and ridge beam 1000 may not necessarily require any further support, such as by the insertion of a separate beam.

Referring now to FIG. 12A, in which like reference numerals are used as in FIG. 10, with the first digit incremented to 12, an alternate ridge beam 1200 is shown. In the ridge beam 1200, the first 1214 and second 1216 roof panel connectors each comprise a connector lower wall 1226, 1228, respectively, extending outwardly and downwardly from the central section 1204. The connector lower walls 1226, 1228 each define a seating surface on which the respective inner ends 105c, 105d of the panels 108c, 108d (shown in FIG. 11) may rest. Similarly to the ridge beam 1000, the central section 1204 and connector lower walls 1226, 1226 may be integral, unitary portions of a single extruded lineal.

Referring to FIGS. 12A and 12B, a roof assembled with the ridge beam 1200 may further include a cap 1300 securable to the ridge beam 1200 over the inner ends 105c, 105d of the panels 108c, 108d. The cap 1300 may comprise a first cap wall 1302 for covering inner end 105c of the first panel 108c, and a second cap wall 1304 for covering the inner end 105d of the second panel 108c. The cap 1300 may be slidably receivable on the top 1006 of the central section 1004, and may be snapingly secured thereto. The cap 1300 may be an extruded lineal, and may be a plastic such as a vinyl.
