Description

[Detailed Description of the Invention] The present invention absorbs the expansion and contraction of architectural boards due to temperature changes at the joints, eliminates thermal stress, and prevents distortion.
This invention relates to an outer enclosure such as a roof or wall that can improve the rain protection of the joints, can be constructed simply and quickly, and can also improve heat insulation performance.

First, the applicant "researched and developed a so-called horizontal cost building board in which one end of the lower building board is engaged with the other end of the same upper building board, and this is repeated sequentially. Going further, it was agreed that the longitudinal direction should be set to an appropriate length and the mutual ends should be fixed continuously using joint fittings.However, due to the climate of the area where the outer enclosure will be constructed and the material of the building boards. w Depending on the length, etc., the degree of expansion and contraction of the architectural board may become significant, and this causes heat 6 force ~ A large deformation strain occurs in the architectural board, which not only deteriorates the appearance but also deteriorates the strength. There have been disadvantages such as weakening of the board, the occurrence of the "board hahajima" phenomenon, poor rain control, and in extreme cases, the construction board may come off and be damaged. Vertical beams with a hat-shaped cross section are fixed to structural materials at appropriate intervals, and flat U-shaped portions are attached between the horizontal parts of adjacent vertical beams at appropriate locations in the plurality of vertical beams. A hidden subject with horizontal greenery extending outward from both upper ends of the main plate is placed, a sloping green is provided downwardly inwardly from the front end of the main plate, and a protruding strip extending upwardly inwardly from the rear end of the main plate is bent. The longitudinal direction of the construction board with a horizontal attachment part provided at the rear end of this protruding strip is set to an appropriate length, and the construction board is layered so as to be approximately perpendicular to the vertical beam material and the hidden gutter. The horizontal mounting part is fixed to the vertical beam material so that one end in the longitudinal direction is within the flat U-shaped part of the hidden gutter material, and the other end in the longitudinal direction of the adjacent construction board is attached to one end of the construction board. The edges are overlapped, a hanging edge is formed at the front end of the main joint plate, and a fitting with an upward folded edge formed at the rear end of the main joint plate is placed on the overlapped part, and the hanging edge is bent into an inclined green shape. Then, fix one side of the joint main plate to the edge of the building board on one side, and repeat these steps in order to secure the lower building board, and then tighten the slanted edges of the upper building board. Engage with the protruding strip and folded edge of the lower stage and repeat them in order, or interpose a waterproof sealing material in the joint main plate of the above configuration,
Alternatively, by providing a heat insulating material, a heat insulating plate, etc. to the above structure, at the joint fittings, the longitudinally adjacent building boards are not fixed to each other but only overlap, and the building blocks due to temperature changes Expansion and contraction of the board can be absorbed at the point where it overlaps, and the architectural board does not experience thermal stress or deformation strain.This prevents the board from becoming sagging, and increases its strength over a long period of time. It can give an elegant appearance, and even if rainwater enters the back side from the polymerized area, it will be caught by the rope U-shaped part of the hidden gutter material, and from there it will flow outside and prevent it from entering indoors. In addition, since it is not a long construction board, it is easy to handle and can be constructed quickly, and by installing heat insulating material and heat insulating boards, we provide a product that improves insulation performance and prevents cold bridges. .

Next, the structure will be explained with reference to the drawings.

It is a long structural member such as a cross beam installed at a relatively large interval on the top or side of a structure.

2 is a long vertical beam member with a hat-shaped cross section;
Horizontal portions 4, 4 are integrally formed outside both lower ends of.

One horizontal part 4 or both horizontal parts 4 of the vertical beam village 2,
4 has a plurality of sharp tongues 5 cut and raised by press working or the like, and provided at predetermined intervals in the longitudinal direction of the horizontal portion. The tongue piece 5 may not be provided in some cases. (See Figure 4). A plurality of the vertical beam members 2G, structural members 1, 1, . There is. This fixing is actually done by welding.
Reference numeral 6 is a long hidden piece of equipment in which "horizontal greens 8, 8 are integrally molded outward from both upper ends of the fan-flat U-shaped part 7.

The height of the fan flat U-shaped portion 7 is formed to be approximately equal to the height of the vertical beam material 2 described above. The hidden gutter village 6 is interposed between the vertical beam members 2, 2, . That is, the flat U-shaped part 7 of the togakure gutter material 6 is layered on the opposing horizontal parts 4, 4 of the adjacent vertical beams 2, 2, and the horizontal greens 8, 8 are layered on the gate-shaped part 3, 3 There is a battle layer on the top surface. No tongue piece 5 is provided in the horizontal part 4 that covers the hidden gutter material 6. Furthermore, the distance between the hidden gutter members 6 in the direction in which they are installed is actually approximately 5 cm to 1 cm. 9 is a construction board, and its length in the longitudinal direction is
It is transportable and easy to handle, and is formed in a length (for example, about 5 cm to 1 cm long), and has a mirror beveled edge 11 that extends diagonally downward and inward from the front end (the near side in FIG. 8) of the main plate 10. A protruding strip 12 having an acute-angled cross section facing upward and inward is formed at the rear end (rear side in FIG. 8) of the main plate 10, and a horizontal mounting portion 13 is bent rearward from the rear end.
An edge 14 having a height slightly higher than this rear end is formed to rise. The main plate 10' may be bent in an inverted F-shape as shown in the figure, or may be formed flat. Further, the main plate 10 portion at one end in the longitudinal direction of the architectural board 9 may be provided with a bent portion 15 that is slightly bent downward. (See Figure 8). The construction board 9 is sent out so as to be substantially perpendicular to the vertical beam materials 2, 2... and the hidden gutter material 6, and the construction board 9
One longitudinal end of the hidden gutter material 6 is located within the flat U-shaped portion 7 of the hidden gutter material 6, and its horizontal mounting portion 13 is fixed at a suitable position with a bolt or the like. One end of this construction board 9 is overlapped with the other end of the adjacent construction board 9 in the longitudinal direction. The main plate 101, which is the lower side of this overlapping part, is attached to the bent part 1 as necessary.
5 is formed. Reference numeral 16 denotes a joint metal fitting with a hanging green 1 attached to the front end of the joint main plate 17 (on the near side in Fig. 9).
8, and an upward folded edge 19 is integrally molded at the rear end.

Is the length of the joint main plate 17 in the front-rear direction and the cross section seen from the side the width of the main plate 10 of the above-mentioned architectural board 9? It is the same as the cross section, and is bent in an inverted F-shape (see Figures 2 and 9).
, or may be formed flat. The return green 1
The length of the main joint plate 17 when viewed from the front is larger than the width of the main joint plate 17, and the rear part of the main joint plate 17 is formed to gradually widen toward the rear. (See Figure 2 and Figure 9). Alternatively, the length of the folded edge frame 9 may be made equal to the width of the joint main plate 17. moreover,
There are a plurality of cross-sectional shapes of the joint main plate amount 7 viewed from the front. In the first embodiment, bulging stripes 20, 20 are formed near both sides of the main plate 17, and two wings, 21 are formed outward from the outer ends of the ridge portions, which are slightly lower than the position of the main plate wing 7 of the joint. There is. The bulging strip 201 is formed from the front end of the joint main plate 17 to near the rear end, and a bulge portion 22 is formed in a substantially central portion of the joint main plate 17 excluding the periphery thereof. (Figure 2,
(See Figure 3, Figure 9L, Figure 0). The second example is
The third embodiment is a slight modification of the first embodiment, in which the green portion 21 and the joint main plate turtle 7 are formed at the same height (see Fig. 4). (See Figure 4) except for the green parts 21, 21.
(See Figure 5). In the fourth embodiment, only the bulging portion 22 is provided.
The outer periphery of the joint main plate 17 is formed into a flat shape (see FIG. 6). The fifth embodiment is formed only in a flat shape (see Fig. 3). The joint main plate 7 of such a joint fitting 16 is connected to the main plate E of the longitudinally adjacent architectural board 9;
Q? 1q overlapped part, and at the same time its folding edge 9
is brought into contact with the front edge of the protruding strip 2 of the overlapping part, and its hanging edge 98 is bent and engaged with the inclined edge 18' of the overlapping part. At this time"
A tape-shaped waterproof sealing material 23 made of synthetic resin or rubber may be interposed between the joint main plate 17 and the king plate tendon Q of the architectural board 9 (Figs. 2, 3, and 7). (see figure). This waterproof seal 23 is often provided in the form of a band on both sides of the back surface of the joint main plate 17, but sometimes it is a single piece and is provided on the entire back surface of the joint main plate 17. This waterproof sealing material 23 is not installed in areas with little rainfall. (See Figures 4 to 6). Then, one side of the joint main plate 17 and one of the ends of the main plates 10, 10 of the architectural plates 9, 9 adjacent to each other at the overlapping portion are fixed with a sharpened pet or the like. That is, the adjacent building boards 9, 9 are constructed only by polymerization and not fixed to each other. By repeating these steps one after another, the building boards in the same row are approved. Then, with the position of the lower joint fitting 16 placed halfway between the upper architectural board 9, 12 and the folded edge ?9 of the joint metal fitting 16.In the longitudinal direction of the upper stage, the same row is connected via the joint metal fitting 16 in the same manner as described above, and these steps are repeated sequentially to prevent external objects such as roofs or walls from forming. The horizontal mounting part 13 at the position of the joint fitting 16 in the lower part of the architectural board 9 is cut to an appropriate width and bent so as to fall into the fan-flat U-shaped part 7. (See Figure 2).This notch is ~
The desired overlapping location of the upper construction board 9 is covered.
(See Figure 2). Further, the notch portion may not be provided in some cases. Is it a heat insulating material such as 2W foamed synthetic resin, and the flat U-shaped part of the hidden gutter material 6? The back side and its hidden gutter material 7
It is sometimes installed by spray-painting between the back surfaces of the two vertical beams 2 and 2 that depict the battle hawks (see Figures 2 and 3).

Reference numeral 25 is a heat insulating board made of wood wool, foamed synthetic resin, glass wool, etc., and its thickness is equal to the height of the gate-shaped portion 3 of the vertical beam material 2.

This heat insulating board 25 is designed to cover the horizontal part 4 on the opposite side to the horizontal part 4 on which the hidden gutter material 6 is placed, the horizontal part 4 of the adjacent vertical beam material 2, or each of the other adjacent vertical beams 232. Horizontal part 4, 4
There is a layer of bushes on top, and its tongue piece 6 sticks through a heat insulating board 251 (see Figures 2 and 3).This heat insulating board 25 is also installed as required. Both the insulation material 24 and the insulation board 25 may not be installed at the same time (see Figure 4).Also, when installing the insulation board 25, a moisture-proof material such as asphalt roofing is required on top of the insulation board 25. Rainwater sealing material 26 may also be attached to the back surface of either side of the main plate 10 of the architectural boards 9, 9 adjacent to the overlapping location, near the light end (second (See Figures to Figures 4).Also,
In the above explanation, the vertical beams 2 are installed on the structural material, but there are cases where a large number of vertical beams 2 are installed on the top surface of the concrete structure etc. at appropriate intervals without using this, and other configurations may be used. I agree with this as in the case of Figure 1. In this case, the insulation material 24
A heat insulating board 25 is not provided. Next, the effects will be explained. First, in the invention described in claim 1, the longitudinal direction of the building board 9 is set to an appropriate length, and the building board 9 is orthogonal to the vertical beam members 2, 2, so that the horizontal mounting portion 13 is fixed to the vertical beam material 2, one longitudinal end of the architectural board 9 is overlapped with the other longitudinal end of the adjacent building board 9, and a joint fitting 16 is attached to this overlapping location, Since one side of the joint main plate 17 of the joint fitting 16 was fixed to the end of the building board 9 on one side, the adjacent building boards 9.9 were not fixed to each other but only overlapped, resulting in a large temperature difference. Even if the building boards 9 are constructed in a local area or are made of a material with a high degree of elasticity, when the building boards 9 expand or contract, they will shift from each other at their overlapping locations to absorb the expansion and contraction.

Therefore, thermal stress is not generated in substantially the entire architectural board 9, and in particular, almost no deformation strain is generated in the main plate 10 exposed on the outer surface. For this reason, it not only maintains an elegant appearance over a long period of time, but also eliminates the problem of weakening of strength due to distortion, resulting in a durable product, and also prevents the plate Q-bird phenomenon caused by distortion. be able to. Here, since the horizontal attachment part 13 of the building board 9 is fixed to the vertical beam material 2 with bolts etc., distortion may occur here. Since the protruding stripes 12 with a large section modulus are continuously formed, there is very little distortion in the thermal stress at the fixed location, and this distortion is hardly transmitted to the main plate 10, The part where distortion occurs is the main plate 1 of the upper architectural board 9
0, and in experiments, no distortion was observed from the outside. Although it is possible to absorb expansion and contraction in the longitudinal direction in this way, complete adhesion of the overlapping parts cannot be obtained. , 2, a hidden gutter material 6 with horizontal greens 8, 8 formed outwardly from both upper ends of the fan-flat U-shaped portion 7 is interposed, and a construction board 9 of an appropriate length is inserted in the longitudinal direction. One end of
The hidden gutter material 6 is placed within the flat U-shaped part 7, and the other end of the adjacent construction board 9 in the longitudinal direction is overlapped with one end of the hidden gutter material 6. Since one side of the joint main plate 17 is fixed to the end of the building board 9 on the other side, rainwater can enter from between the joint main plate ]7 and the main plate 10 of the construction board 9 due to wind pressure, etc. Even if rainwater infiltrates into the overlapping area from
It flows down to the fan flat U-shaped part 7 and is caught by the fan flat U-shaped part 7,
From there, it flows outside and prevents rainwater from entering indoors, providing extremely good rain control. In addition, the architectural board 9 of the present invention is provided with a beveled edge 11 extending downwardly and inwardly from the front end of the main board 10, and a protruding strip 12 extending upwardly and inwardly from the rear end is bent and horizontally mounted on the rear end. A portion 13 was provided, this was made to have an appropriate length in the longitudinal direction, and this was sequentially overlapped, and a hanging edge 18 was provided at the front end of the joint main plate 17 at the overlapped portion, and an upwardly folded folded edge 19 was formed at the rear end. By overlapping and attaching the joint fittings 16 from above, the joints are not installed from the back side as in the past, and the installation of the same row can be done easily and quickly without requiring any skills. On top of these architectural boards 9, 9......, the oblique edges 11 of the upper architectural boards 9 are removed by a simple operation of engaging with the lower projecting strips 12 and folded edges 19. Able to work on surroundings. Moreover, unlike long ones, it is easy to handle, and construction efficiency can be increased, resulting in relatively low construction costs. Further, the upper and lower construction boards 9 are engaged, and the folded edge 19 of the joint fitting 16 is pressed by the inner surface of the slanted edge 11 of the upper construction board 9, and the hanging edge 18 is pressed against the slanted edge 11. It is bent and engaged with the edge 11, and the building boards 9, 9 in the same row are also firmly connected to each other, so that the entire outer case can be made strong. In addition, since a plurality of vertical beams 2 having a hat-shaped cross section are fixed at appropriate intervals to the structural material 1, etc., the cross-sectional modulus of the vertical beams 2 themselves is large, and this serves as the framework of the outer enclosure. It can be made into a strong exogenous body. Next, in the invention described in paragraph 2 of the scope of patent appeal,
In addition to the above invention, since the joint fitting 6 is placed on the overlapping part of the adjacent building boards 9 through the waterproof sealing material 23, rainwater when there is wind pressure can be absorbed by the joint main plate 17.
Even if an attempt is made to intrude between the main slope 10 of the building board 9 and the main slope 10 of the building board 9, it can be blocked by the waterproof sealing material 23, and it is possible to provide an outer enclosure that can more reliably shut off rain.

In addition, the present invention naturally achieves the effects of the invention set forth in claim 1.In the invention set forth in claim 3, a heat insulating material 24 is provided on the back surface of the hidden gutter material 6, and the One vertical beam material 2 on which hidden gutter material 6 is placed and the adjacent vertical beam material 2
, or on the horizontal parts 4, 4 of the vertical beams 2, 2 in other neighboring bushes, respectively, with heat insulating boards 25 placed on top of them, and building boards 9, 9, etc. placed on top of these.

It is possible to block rainwater from entering between the roof and the roof, making rain control even better.
