Abstract

PURPOSE:To simplify the execution of works by engaging the upper-side engaging edge of a face plate at a lower stage by the upper-side side face of an inverted hat-shaped sectional face-plate fixing material and interlinking the lower-side engaging section of a face plate at an upper stage by the upper lower-side bent section of the fixing material. CONSTITUTION:Face-plate fixing materials 4, which have inverted hat-shaped cross sections and in which each face or both side faces are punched to form porous surfaces, are placed along the upper side edges 3 of face plates 1 at a lower stage. The upper side edges 3 of the face plates 1 are retained by the upper-side side faces 4a of the face-plate fixing materials 4, and the face plates 1 are held down by the bases 4b of the face-plate fixing materials 4 and fixed onto rafters 5 by screws, etc. The upper sections of the face-plate fixing materials 4 are bent at right angles in the longitudinal direction, and the lower-side engaging sections 12 of face plates 11 at an upper stage are engaged by lower-side bent sections 4c. Accordingly, ventilation structure, in which insect-proofness and a bird protective net, etc., are unnecessitated, can be formed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a natural ventilation structure for a roof or wall surface of a building having a metal face plate.

[0002]

2. Description of the Related Art Conventionally, various types of natural ventilation buildings have been proposed, but all of them are complicated in structure, require skill to install, and are expensive. The roof construction work must be done by the roof builder, but the roof builder generally works with simple tools such as scissors or electric tools, and the welding work is done like the iron builder. It is often not suitable for heavy work such as.

Further, among conventional natural ventilation structures for roofs, there are some that can be easily constructed with fasteners such as screws, bolts or claw pieces.

For example, in Japanese Utility Model Publication No. 63-1700, the bent face plates are partially overlapped and attached to the vertical rails, and the face plates bent to the vertical rails are also attached at intervals inside. Alternatively, as in the invention of Japanese Examined Patent Publication No. 2-14503, there is one in which curved face plates are faced and attached to both sides of one pillar.

[0005]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The invention of No. 700 and the invention of Japanese Examined Patent Publication No. 2-14503 are both incomplete in preventing rainwater from entering the room because they both have a structure in which rainwater is introduced into the curved outer surface plate.

Further, since the face plate for the ventilation structure used in the above invention uses a member different from the face plate forming the roof surface or the wall surface, in order to form the ventilation structure by connecting it to the roof surface, A special connecting member or processing is required.

Furthermore, in the above-mentioned device, insects, birds, dust, etc. enter through the gaps between the face plates for the ventilation structure, so that an insect-proof net or punching metal must be attached separately.

[0008]

SUMMARY OF THE INVENTION Therefore, the present invention provides a structure in which a roof surface or wall surface is formed by laterally laying a metal face plate, and even a general roof builder can easily construct the roof surface or the ventilation structure. By using the same structure for the face plate and the roof plate or the wall plate so that the ventilation structure can be constructed by connecting to the roof plate or the wall plate, not only the roof ridge but also the roof In addition to allowing the ventilation structure to be placed at any position in the middle part of the wall, and also on the wall surface, by using a punched member as a fixing material for the ventilation structure, it can also serve as insect repellent. In addition, it is not necessary to install insect repellent, bird net, etc.

According to the present invention, in order to provide a ventilation opening in the ventilation structure portion, the lower edge of each face plate is made higher than the lower face plate, and a fixing member having an inverted hat-like height for providing a space therebetween is arranged. Then, the lower edge of the face plate was attached, and the upper edge of the lower face plate was pressed against talc or the like with this fixing material to be fixed, thereby forming each face plate in a step structure. Further, the surface of the fixing material is punched so that ventilation can be performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in the drawings will be described below.

As the horizontal roofing metal plate 1, there is known a structure having an inverted U-shaped engaging portion 2 at a lower side edge and an engaging portion 3 standing upward at an upper side edge, and a lower stage. There is also known a lateral roofing method in which the engaging portion of the face plate and the engaging portion of the upper face plate are sequentially meshed to form a roof surface or a wall surface.

The present invention is to form a ventilation structure by using this known long face plate having an engaging portion or a locking portion at the upper and lower edges, and as shown in an enlarged view in FIG. A face plate fixing member 4 having an inverted hat shape in cross section and punched at each side or at least both side faces to be a porous surface is used, and the face plate fixing member 4 is arranged along the upper edge 3 of the lower face plate 1 thereon. Then, the upper edge 3 of the face plate is locked by the upper side face 4a of the face plate fixing member 4, and at the same time, the face plate is pressed by the bottom face 4b and fixed to the talc 5 with screws or the like.

The upper portion of the face plate fixing member 4 is bent substantially at a right angle in the front-rear direction, and the lower engaging portion 12 of the upper face plate 11 is engaged with the lower bending portion 4c.

The lower bent portion 4c of the face plate fixing member 4 is the face plate 1
If the downward bent portion 4d is formed in accordance with the bent width of the lower engaging portion 12 to the lower side, the engagement becomes dense and reliable, which is advantageous. The central portion along the longitudinal direction is bent at an appropriate angle according to the height of the face plate fixing member 4 or the roof slope (bent portion 6). Then, the face plate fixing material is similarly used for the next face plate to raise the roof.

In this way, the ventilation structure can be formed on the roof or the wall surface on the extension of the conventional face plate, and the conventional face plates can be connected again if necessary.

In the ventilation structure, a step corresponding to the height of the face plate fixing member 4 is generated between the face plates of each step, and each face of the face plate fixing member is punched to form a porous surface. It will be possible to ventilate through.

When the ventilation part B is inclined with respect to the roof part A as a ridge, the roof plate 21 at the connection part between them is bent at a steep angle as shown in FIG. It is also possible to form an auxiliary roof C on the back side of, and connect the roof plate 31 of the connecting portion from the roof portion A to the auxiliary roof C so that the ridge portion has a double structure.
FIG. 3 shows wall siding.

[0018]

Since the present invention is configured as described above, the lower edge of the upper face plate is located substantially above the center of the lower face plate, and the face plate fixing member 4 having a porous surface is used as the vent hole. Since there is no risk of rainwater ingress, even if it does, the upper locking edge 3 of the lower face plate
Since it is stopped at the rising part of the upper part of the
Moreover, since the fixing material prevents the invasion of insects, there is no need for an insect-proof net.

Further, since the roof and the face plate that covers the wall surface are continuously used as they are as a ventilation structure material, there is no discomfort in the design, and there is no need for a special member for connection with them, and it is easy. Construction work can be done by a roof builder.
