In particular, the present invention relates to a construction board and its envelope, which can have a strong envelope structure and can be constructed relatively easily and quickly.

[Conventional technology and its problems]

The applicant has already conducted various research into enclosures such as roofs or walls that are constructed by fitting adjacent architectural boards together.
We are developing. These have excellent workability, but if strong wind pressure (negative) is applied to the mating part,
There was a problem that the attachment point to the structural material was relatively weak. Also, if the architectural board is wide, etc.
Inconveniences have also occurred, such as a decrease in strength and the occurrence of a plate ringing phenomenon. There are also demands for further reduction of thermal distortion, etc., and for reliable protection against rain and rust prevention.

[Means to solve the problem]

Therefore, as a result of intensive research in order to solve the above-mentioned problem, the inventor has developed an invention in which the other side of the main plate is bent upward to form a bulge, and the bulge is extended outwardly from the outer end of the bulge. The protruding strip facing towards the main plate is bent, one side of the main plate is bent upward, and then bent into a substantially O-shape, the upper side becomes a protrusion, and the lower side can be fitted with the protruding strip of an adjacent architectural board. The groove is formed as a concave groove, and an upwardly directed protrusion is formed in the middle of the O-shaped bottom. A side part is formed above, a downward folded edge is provided inwardly or outwardly from the upper end, and the upper end of the side part is formed so as to be able to support the side of the protruding part of the adjacent construction board, and the The construction board may be a construction board with a bent intermediate protrusion having a downward dovetail groove in the middle of the main board, or the construction board may be placed perpendicular to the structural material, and the construction board may be mounted from one side of the horizontal mounting part. Place the chevron-shaped protrusion of a washer provided with the chevron-shaped protrusion on the protrusion and the horizontal mounting part on the bottom between the protrusion and the side part, and attach the bolt, etc. from above the horizontal mounting part of the washer. Attach the architectural board to the structural material using By fitting the protruding strips of the board and building the outer shell by repeating these sequentially, the strength of the building board itself is superior, and the permissible dimensional error of the standard material can be adjusted at the folded edge. It does not cause any inconvenience during construction, there is no need to cut the material to a certain width, it is better from a rust prevention standpoint, and even if the building board is wide, it can be made stronger by the presence of intermediate ridges. In addition, the ridges on the outer envelope serve as reinforcement and can also be used as a rainwater barrier, making it even better at shutting down rain, and by supporting the ridges with washers, wind pressure ( Even if the construction board (mainly the main board) is wide, by attaching the intermediate protrusion with a mounting bracket, it is possible to increase the strength of the mating part against the negative). This method solves the above-mentioned problems by making it possible to prevent the above-mentioned problems, and also to make the entire envelope strong, and to almost prevent the occurrence of distortion, etc.

〔Effect of the invention〕

First, in the invention described in claim 1, the other side of the main plate 1 is bent upward to form the bulged portion 8.
A protruding strip 9 extending outward from the outer end of the bulging portion 8 is bent and formed, and one side of the main plate 1 is bent upward, and then bent into a substantially O-shape so that the upper side becomes the protruding portion 2. , the lower side is formed as a concave groove 3 into which the protruding strip 9 of the adjacent architectural board A can fit, and the Otsu-shaped bottom part 4 is formed.
An upwardly directed ridge 5 is formed in the middle of the ridge 5, and the bottom 4 on the outer side of the ridge 5 is formed to be able to be fixed on the structural member 12, and a side 6 is formed above the outer end of the bottom 4. A downward folding edge 7 is provided inwardly or outwardly from the edge, and the upper end of the side portion 6 is formed to be able to support the inside of the bulging portion 8 of the adjacent architectural board A, and the main plate 1 By forming the architectural board A in which the intermediate protrusion 10 having a downward dovetail groove 11 is bent in the middle thereof, in this cross section, there are O-shaped parts bent as appropriate in the vertical or inclined direction on both sides of the main board 1, Projection 5
There are many side parts 6 folded edges 7 bulging strips 9, etc., the overall section modulus is increased, even thin materials can be made strong, and architectural boards can be provided that are good as roofing materials and wall materials.
In particular, the intermediate protrusion 5 and the intermediate protrusion 10 of the bottom portion 4
can be reinforced as described above.

Furthermore, when the concave grooves 3 and the protruding strips 9 of the architectural boards A and A are fitted together, even if rainwater infiltrates for some reason from the mating point, the protruding strips 5 will prevent the rainwater from entering. It acts as a barrier against intrusion and flows out from the tub-shaped portion of the bottom 4 between the protrusion 5 and the groove 3, making it possible to more reliably shut down the rain.

Furthermore, since the bottom part 4 on the outer side of the protrusion 5 can be fixed on the structural member 12, even if the bottom part 4 is fixed with bolts 16 etc., the bottom part 4 can be fixed to the protrusion 5 and the side. 3, and is separated from the 3 recesses where rainwater can enter by a protrusion 4, preventing rainwater from reaching the 16 bolts that are most prone to corrosion and preventing rust. There are advantages that can be achieved.

In addition, by forming the upper end of the side part 6 to be able to support the inner side of the bulging part 8 of the adjacent building board A, the bulging part 8 can be point-supported at the upper end of the side part 6.
The bulging portion 8 can be stably supported. Moreover, the outer enclosure can be constructed simply and quickly by only fitting and fixing the bottom part 4.

By the way, the standard material used as the base material for forming general construction boards has a tolerance dimension on the plus side, and when roll-forming is performed using this material, the edges of the construction board The width of the standard material is often cut to a consistent width using a slitter to prevent this from happening. It was also possible to roll form the material into the desired architectural board. In this regard, in the present invention, a side part 6 is formed, a downward folded edge 7 is provided inwardly or outwardly from the upper end, and the bulge part 8 of the adjacent building board A is formed at the upper end of the side part 6. By forming the inside of the part so that it can be supported, the end of the part does not need to be cut with a slitter.
Even if the width of the standard material becomes wide within the allowable range, it will only be formed a little longer as shown by the dotted line in Figure 4, and there will be no inconvenience during construction. In addition to being inexpensive, the edges of the standard material are generally better rust-proofed than other parts, and as a result, the building board A of the present invention itself can be made suitable from the standpoint of rust-prevention.

In particular, the intermediate protrusion 10 having the downward dovetail groove 11 can reinforce the wide main plate 1, and
It forms the main structure of attaching the middle of the main plate 1 to the structural member 12, and even if this is installed, the working width of the member can be secured sufficiently, and it is possible to reduce the construction cost by roofing etc. There are advantages.

Next, in the patented invention recited in claim 2, the building board A recited in claim 1 is placed perpendicularly to the structural member 12, and from one side of the horizontal mounting portion 14 The shaped protrusion 15 of the washer 13 provided with the chevron-shaped protrusion 15 is placed on the protrusion 5, and the horizontal mounting part 14 is placed on the bottom 4 between the protrusion 5 and the side part 6,
The bolt 1 is inserted from above the horizontal mounting part 14 of the washer 13.
Attach the architectural board A to the structural member 12 with a screw 6 or the like, fit the protruding strip 9 of the adjacent architectural board A into the groove 3,
By repeating this process one after another to form an outer enclosure, when strong wind pressure (negative) is applied to the O-shaped part and bulge part 8 at the fitting part, and a tensile force is applied to lift it upward. This force is applied to the attachment part of the bottom part 4 (the part where the bolt 16 etc. is fixed), but in the process of being applied, it is applied to the protrusion 5 on the side of the recessed part 4. The upper side of the protrusion 5 is pressed by a shaped protrusion 15 connected to the horizontal mounting part 14 of the washer 13, and is fixed by the washer 13 having a larger pressing area than the mounting part of the bottom part 4. Depending on the conditions such as what you are doing,
The fixing support force of the bottom portion 4 against the tensile force is increased, the fitting becomes strong, and an outer enclosure having an extremely strong fitting portion can be provided. Furthermore, when the five protrusions are pressed and fixed with the chevron-shaped protrusions 15 of the washer 13, the strong wind pressure (negative) described above will cause
Suppose that a tensile force is applied to the bottom 4 (toward the left in Fig. 4).
Even if the bolt 16 of the washer 13 is attached, the protrusion 5 acts as an expansion and absorbs the external force, resulting in a strong installation. By enlarging the bolt hole, it is possible to prevent damage that may lead to rain leakage.

Further, in the present invention, the locking plate 20 of the mounting brackets 20, 21 is provided in the dovetail groove 11 of the intermediate protrusion 10.
a, 21a, and the mounting brackets 20, 2
Since the lower part of 1 is fixed to the structural member 12, the width of the architectural board A, that is, the main board 1 is wide, or the board is particularly thin or the material is weak in strength. etc., the middle of the main plate 1 is the structural material 1.
Since it is supported and fixed by the bottom part 2, the strength of the attachment of the bottom part 4 acts synergistically, making it possible to construct an extremely strong outer enclosure. Furthermore, the occurrence of plate rattle phenomenon on the main plate 1 can be prevented. In particular, by locking in the dovetail groove 11, it can be mounted with sufficient strength using only vertical tightening force, so the locking plates 20a and 21a can be of simple shape. can. In addition, in the outer enclosure, the parts attached to the structural material 12 are the bottom part 4 and the intermediate protrusion 10 via the washer 13, and the adjacent architectural plates A and A are not fixed to each other but are fitted together. Therefore, even if building board A expands and contracts due to changes in outside temperature, the direction in which it is installed will be
Expansion and contraction can be absorbed by the phenomenon of left and right misalignment of the mating point, and expansion and contraction in the longitudinal direction can be accommodated.
The intermediate protrusion 10 can be freely moved relative to the structural member 12 by locking with the locking plates 20a, 20a, and does not generate thermal stress or thermal strain on the intermediate protrusion 10 and the main plate 1. Moreover, thermal stress due to thermal expansion and contraction in the longitudinal direction occurs at the attachment part of the bottom part 4, but the protrusion 5 and the groove 3, which are slightly away from the attachment part,
The protrusion 2 is continuous and has a reinforcing part that increases the section modulus, so that the thermal stress is hardly transmitted to the main plate 1, and the main plate 1 is prone to thermal strain.
The occurrence of thermal strain can also be substantially prevented. In addition, the mounting portion where distortion occurs is located inside the fitting portion, and the main plate 1, etc., which forms the external appearance of the enclosure, can be made to have excellent architectural beauty without causing distortion. Furthermore, the enclosure can be made to be less likely to suffer damage such as distortion due to vibrations such as earthquakes. Further, construction of the outer enclosure of the present invention can be completed by fitting one type of architectural boards A and A, attaching the bottom part 4 and intermediate protrusion 10, and repeating these steps in sequence. , there is no on-site processing work, and no skill is required.
It can be constructed relatively easily and quickly. Furthermore, the construction board A has the same configuration as the construction board of the invention in item 1, and can exhibit the same effects as the invention in item 1.
