Description

The present invention relates to auxiliary metal fittings suitable for use in auxiliary connection of interlocking building material panels used to construct roofs and walls of ordinary houses, offices, condominiums, welfare facilities, resort facilities, etc.

Interlocking building material panels have traditionally been widely used as roofing materials, and panels have been joined together by interlocking the top and bottom seams at the widthwise ends of the panel body with the bottom and top seams of other adjacent building material panels, respectively. However, in recent years, building material panels have also been developed that have top and bottom joints provided in the longitudinal direction of the panel body, and that interlock the top and bottom joints with adjacent building material panels arranged below and above the water, respectively, to join the panels together; for example, see Patent Document 1 for prior art in this regard.

However, when strong winds or excessive negative pressure are applied to the above-mentioned conventional building material panels, deformation cannot be ruled out at the joints between the panels, and there is still room for improvement.

Figure 1 is a schematic external perspective view of the auxiliary metal fittings for connecting interlocking building panels according to the present invention. Note that the auxiliary metal fittings are made of galvanized steel sheets having a thickness of about 1.0 to 3.2 mm.

In Figure 1, reference numeral 1 denotes a plate-like body of an auxiliary connecting fitting. Plate-like body 1 covers the upper surface of the lower joint of an interlocking building material panel, thereby preventing deformation of the lower joint and upper joint at the joint of the interlocking building material panels. Reference numeral 2 denotes a base that is integrally connected to plate-like body 1 and fixed to the base material of a roof or wall via fastening means such as screws or bolts. Plate-like body 1 and base 2 can be manufactured by press-molding a single sheet of plate material.

Figure 2 is an external perspective view showing an interlocking building panel suitable for use with the above-mentioned connecting hardware, Figures 3(a) and 3(b) are enlarged views of the A-A and B-B cross sections of Figure 2, respectively, and Figure 4 is a view showing the C-C cross section of Figure 2.

When laying a roof or constructing a wall, the interlocking building material panels are positioned so that the side with the lower joint faces above water and the side with the upper joint faces below water, and multiple interlocking building material panels with the same configuration are used to construct the roof and walls of a building structure.

Materials used to construct the interlocking building panels include galvanized steel sheets, aluminum-zinc alloy plated steel sheets, copper sheets, aluminum sheets, stainless steel sheets, or painted or coated steel sheets of these materials, all with a thickness of about 0.2 to 1.0 mm.

The reference numeral 3 in Figures 2 to 4 denotes the panel body. The panel body 3 has an overall rectangular contour defined by a pair of long edge portions 3a, 3b extending along the longitudinal direction, and a pair of short edge portions 3c, 3d sandwiching the long edge portions 3a, 3b and extending along the width direction.

The reference number 4 denotes an upper seam that is integrally connected to the long edge portion 3a of the panel body 3 and fits into the lower seam of another adjacent interlocking building material panel to connect the panels together.

The upper seam 4 is composed of an inclined side panel 4a rising from the long edge 3a, a tapered dome-shaped head 4b connected to the upper end of the inclined side panel 4a via a locking jaw t1 and having an internal space that can fit into the lower seam of another interlocking building material panel arranged adjacently in the girder direction, and an inclined side panel 4c that hangs down and is held by the head 4b via the locking jaw t2 and forms a downward opening between the inclined side panel 4a. The upper seam 4 can be provided with a recess extending along the long edge 3a on the side wall of the head 4b, which makes it possible to prevent surface contact between the panels and prevent rainwater from entering when the panel is fitted into the lower seam of another interlocking building material panel arranged adjacently in the girder direction.

The reference number 5 denotes a bottom seam that is integrally connected to the long edge portion 3b of the panel body 3 and fits into the bottom seam of another interlocking building material panel that is placed adjacent to the other panel, connecting the panels together.

This bottom seam 5 is composed of a side panel 5a that rises from the long edge 3b, a dome-shaped head 5b that is connected to the upper end of this side panel 5a via a locking jaw t3 and has a tapered tip that can fit into the upper seam of another adjacent interlocking building material panel, a side panel 5c that hangs down and is held by the locking jaw t4 to the head 5b and forms a downward opening between the side panel 5a, and a screw-fastening piece 5d that is connected integrally to the lower end of the side panel 5c in a horizontal position.

Latching jaws t1 and t2 protrude in opposite directions to each other, preventing the engaged seam from being pulled out. Similarly to the above-mentioned locking jaws t1 and t2, locking jaws t3 and t4 protrude in opposite directions to each other, preventing the engaged seam from being pulled out.

The reference numeral 6 denotes a lower joint provided on the short edge 3c of the panel body 3. The lower joint 6 is overlapped under the upper joint of another interlocking building material panel adjacently arranged on the above-water side, and is composed of a plate-like body 6a that is connected flush over the entire short edge 3c of the panel body 3, a hook piece 6b that is folded back toward the below-water side of the panel body 3 at the rear end of the plate-like body 6a and can be hooked onto the upper joint of another building material panel adjacently arranged on the above-water side, a first seam 6c that is connected to the widthwise edge of the plate-like body 6a and the end of the upper seam 4 and can be fitted into the upper seam (corresponding to the third seam of the upper joint) of another interlocking building material panel adjacently arranged on the above-water side, and a second seam 6d that is connected to the other widthwise edge of the plate-like body 6a and the end of the lower seam 5 and can be fitted into the lower seam (corresponding to the fourth seam of the upper joint) of another building material panel adjacently arranged on the above-water side. At the lower end of the second seam 6d, a tongue piece 6e is provided that is flush with the screw-fastening piece 5d of the lower seam 5.

The lower joint 6 is formed by roll forming to have the same cross-sectional shape as the panel body 3, upper seam 4, and lower seam 5, and then by drawing using press forming.

The width dimension of the lower joint 6 is slightly wider than the width dimension of the panel body of the adjacent interlocking building material panel placed adjacent to the water side (actually the width dimension of the upper joint) so that the panels can be securely overlapped when connecting with other adjacent interlocking building material panels placed adjacent to the water side.

The reference number 7 indicates an upper joint (placed on the underwater side of the panel) provided on the other short edge 3d of the panel body 3. This upper joint 7 is connected flush with the panel body 3 and overlaps with the upper side of the short edge (the part corresponding to the lower joint) of another interlocking building material panel placed adjacently on the underwater side.

The upper joint 7 is composed of a first plate-like body 7a that is connected flush to the panel body 3, a first hook piece 7b that is folded back at the tip of the first plate-like body 7a toward the abovewater side of the panel body 3 and can be hooked onto the lower joint of another interlocking building material panel that is adjacently placed belowwater, and a third seam 7c and a fourth seam 7d that are connected flush to each end of the width of the first plate-like body 7a and to the upper seam 4 and the lower seam 5, respectively.

The first hook piece 7b can be folded back so that it is bent 180 degrees relative to the first plate-shaped body 7a.

The interlocking building material panel having the above-mentioned configuration is basically fixed to the base material of the roof or wall by driving screws into multiple locations of the screw fastening pieces 5d of the bottom seam 5, but as shown in Figure 5, auxiliary connecting fittings according to the present invention are placed on the bottom joint 6 of the building material panel and the auxiliary connecting fittings are fixed to the base material via fastening means such as screws or bolts, thereby auxiliary fixing of the building material panel.

Figure 6 is a cross-sectional view showing the main parts of the joints of interlocking building panels. By using the auxiliary metal fittings according to the present invention, the strength of the joints is increased, so that the joints can be prevented from easily deforming even when strong winds blow in or excessive negative pressure acts on them.

In order to cover a roof using the interlocking building material panels shown in FIG. 2, in order to join the interlocking building material panels in the inter-beam direction, i.e., in the vertical direction, as shown in FIG. 7, the first hook piece 7b' of the upper joint 7' of another interlocking building material panel that is adjacent to the lower joint 6 on the water side is hooked to the hook piece 6b of the lower joint 6, and the first hook 6c of the lower joint 6 is hooked to the third hook 6 of the upper joint 7' of the other interlocking building material panel that is adjacent to the water side. The third seam 7c of the upper joint 7 can be fitted into the first seam 6c' of the lower joint 6' of the other adjacent interlocking building material panel on the belowwater side, and the fourth seam 7d of the upper joint 7 can be fitted into the second seam 6d' of the lower joint 6' of the other adjacent interlocking building material panel on the belowwater side.

To join such interlocking building material panels in the girder direction, i.e., horizontally, as shown in Figure 8, the bottom seam 5 is fitted into the top seam 4'' of another adjacent building material panel, and the top seam 4 is fitted into the bottom seam 5'' of another adjacent interlocking building material panel. By carrying out this work in parallel with the vertical joining work, the roof of the building structure can be erected.

Note that although Figures 7 and 8 do not show the auxiliary connecting fittings according to the present invention, in practice they are applicable to all interlocking building material panels.

When constructing walls of a building structure using interlocking building material panels with the above configuration, the interlocking building material panels can be joined together in the same manner as when laying a roof.

Figure 9 is an external perspective view showing another embodiment of the auxiliary metal fitting according to the present invention. Such auxiliary metal fitting is composed of a curved piece 8 having a U-shaped cross section, and as shown in Figure 10, the lower joint 6 is fitted into the inner recess 8a of the curved piece 8 to cover the outer surface of the lower joint 6, thereby increasing the wind pressure resistance and wind pressure resistance of the joint, and preventing the joint from easily deforming even when a strong wind blows in or excessive negative pressure acts on the joint. The curved piece 8 does not need to be fixed to the base material of the roof or wall, and can be formed by bending a single plate material 180 degrees. The curved piece 8 is set to a length such that the tip of the curved piece 8 slightly protrudes from the lower joint 6 when the curved piece 8 is fitted into the lower joint 6, and it is also possible to form a folded piece, protrusion, cut-and-raised piece, etc., at the tip of the curved piece 8 that faces the inner recess 8a, which prevents the auxiliary metal fitting from falling off the lower joint 6.

The present invention provides auxiliary connecting fittings that can increase the strength of the joints between interlocking building material panels.
