Description

[Detailed explanation of the invention] This invention has a tile-like appearance and a kumite structure with sufficient connection strength in the overlapping parts, so that roofs and external walls can be roofed sequentially from the bottom to the top. To provide a surface structure material for a building that ensures draining with a special cross-sectional shape and is hard to dent even when external force is applied.

Examples of the surface structure material of the present invention will be described below with reference to FIGS. 1 and 2.

This surface structure material a has a locking part 1 bent on the front side on one side of a metal flat plate, and a retaining part 2 bent on the back side on the other side.

For example, by providing a bending line 5 approximately in the middle between the locking part 1 and the engaging part 2, the flat part 3 is formed on the locking part 1 side, and the retaining part 2
The overall cross-sectional shape has an inclined surface portion 4 that is gently inclined toward the side.

In the surface structure material a of the present invention, the locking portion 1 and the engaging portion 2 are further configured to have the following special cross-sectional shape.

That is, the locking part 1 has a rising surface part 7 extending from the flat part 3 and forming an acute angle θ with the flat part 3 that is slightly smaller than 90 degrees, and an upper end of the rising surface part 7. A small ridge 8 is formed by bending the ridge 8, and from the lower end of the ridge 8 there is an engaging portion which is parallel to the plane part 3 or slightly opened and bent in two stages, upper and lower. The facing clamping piece parts 9, 9 and the upper and lower two stages of clamping piece parts 9.9
A horizontal hanger hooking groove 10 formed by being held between
It has a special bent cross-sectional shape in which it is rolled up on the flat side with 1.

Further, the engaging portion 2 is preferably cut off by the bending line 6 and is gently inclined opposite to the inclined surface portion 4, or is substantially parallel to the flat portion 3, so that it has a tile-like appearance together with the inclined surface portion 4. a band surface portion 12 that extends so as to exhibit a shape, a bent portion 13 that extends backward from the band surface portion 12 at a substantially right angle, and a hanging portion 13 that extends from the hanging portion 13 so as to be located approximately on the same plane as the flat portion 3; An insert piece 14 that bends and extends, and a band surface portion 12 as shown in the figure near the end of this insert piece 14.
It has a special bent cross-sectional shape with a drainage groove 15 bent on one side or the opposite side.

Next, a connection state using the surface structure material having a special cross-sectional shape constructed as described above will be explained with reference to FIG.

Figure 3 shows the case where the roof is covered with surface structural materials.
This is the cross-sectional structure at the connecting part when the roof is successively installed so that the locking part 1 is located on the upper side of the slope of the roof.

be.

Reference numeral 16 is a rafter, 17 is a shedding board, and 18 is a roofing material.

Regarding the above connection part, the locking part 1 of the surface structure material A covered on the lower side of the slope of the roof is connected to the retaining part 2 of the surface structure material B covered on the upper side.
It is connected to a kumite structure wrapped in.

The insertion piece 14 of the retaining part 2 enters the inside of the locking part 1 through the gap 11, and the drainage groove 15 prevents water from entering due to capillary action.

Furthermore, the clamping piece 9 of the locking part 1 cooperates with the flat part 3 to hold down the insertion piece 14.

This holding force is an extremely large elastic force because the locking portion 1 has a special cross-sectional shape that is bent in three stages.

For this reason, when there is a change in temperature, each surface structure material expands and contracts even though the locking part 1 is fixed, but it turns up due to the locking part 1 and the engaging part 2 that forms a clasp. Rather, the insertion piece of the retaining portion 2 can be held down reliably.

Each surface structure member is constructed so that the hanging part 13 of the retaining part 2 comes into contact with the end of the clamping piece part 9 of the locking part 1.

Therefore, the clamping piece part 9 is deformed by the hanging part 13 so as to press the insertion piece part 14 of the engaging part 2.

The peak part 8 of the locking part 1 is designed to lightly touch near the bent line 6 of the separation between the engaging part 2 and the inclined surface part 4. The area around the bending line 6 will not dent even if you ride on it or with a slight load such as when there is a lot of snow.

This surface structural material is placed on the roofing material 18 by the rafters 1 shown in the figure.
It may be fixed by a support member (not shown) attached in the same direction as 6, but it may also be fixed by a hanger or a threaded hanger 19 as shown.

When using the suspender 19, the suspender 19 is attached to the ridge 8 of the locking part 1.
In addition, the hanger insertion groove 10 formed between the clamping pieces 9 is held down so that it is firmly gripped.

Therefore, if the hanger 19 is firmly fixed to the sheath board 17 by the screws 20, the locking part 1 will be fixed to the sheath board 17 by the hanger 19 without any slight movement in the vertical direction.
On the other hand, since the locking part 1 extremely firmly holds the insertion piece part 14 of the engaging part 2 assembled with the locking part 1, both the upper and lower parts of each surface structural member are firmly fixed to the shedding board 17. It turns out.

The above explanation is for the case of roofing with surface structural materials, but the same applies to the case of roofing external walls, and the only difference is that the surface structural materials are fixed at columns, beams, etc.

As explained above, the surface structure material of the present invention has a locking part bent on the front side of the plate on one side and an engaging part bent on the back side of the plate on the other side. A bending line is provided so that the lower side rises up to the front side of the plate material and gently slopes between the joint parts, and the above-mentioned locking part has a mountain part and has a parallel surface two steps from the mountain part. The retaining portion has a special cross-sectional shape that is bent and formed in a U-shape in cross section and has an insertion piece on the back side.

Therefore: When roofing is done with this surface structure material, the locking part and the engaging part will be joined together, and the locking part will be bent in three stages and hold the insertion piece of the engaging part with strong elastic force. This prevents the retaining part from curling up and prevents water intrusion due to capillary action, and supports the bending line between the retaining part and the inclined surface part, so even if an external force is applied to this bending line, it will not dent. Without,
Furthermore, when fixing the locking part with a hanger or threaded hanger, the locking part will not move in the vertical direction and will be firmly grasped and fixed.
Therefore, the surface structure material has the effect of being firmly fixed at the top and bottom.
