[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is capable of constructing an outer wall of a building in a short time by simple construction, and is excellent in water leakage resistance and strength after construction, particularly strength against a force acting on the outer surface side due to wind or the like. The present invention relates to a vertical wall material for building construction.

2. Description of the Related Art Outer wall material for construction 9 constituting an outer wall of a building
Conventionally, for example, as shown in FIGS. 5 (a) and 5 (b), a mountain portion 9a and a valley portion 9b are formed over the entire length, and the outer wall material for construction 9 is fixed adjacent to both side edges. What is referred to as siding in which a mountain portion 9a or a valley portion 9b on which the side edge portions of the above are respectively formed is formed, and an engaging piece receiver 9c formed in a concave shape on one side edge as shown in FIG. Also referred to as a spandrel, each of which is formed with a single-plate engagement piece 9d that is inserted into and engaged with the engagement piece receiver 9c of the building outer wall material 9 that is already fixed to the other side edge. Etc. were used.

In constructing an outer wall by using such an outer wall material 9 for construction, in the case of the former siding, one side edge portion of the other siding fixed to the furring strip material 7 of the building is used. The side edge portion of the siding that is fixed adjacently is overlapped on the side edge portion, and when the overlapped portion is the mountain portion 9a, it is again overlapped by the hook bolt as shown in FIG. When the part is the valley 9b, (b) in FIG.
As shown in FIG. 5, the work of fixing to the furring strip 7 of the building by tapping screws is repeatedly performed sideways. In order to construct the outer wall by this siding, fixing bolts and screws are passed through both side edges of the siding, and the furring strip 7 of the building is used.
Since there is an advantage in that the number of fixing bolts and screws can be increased, the strength against negative pressure due to wind or the like, that is, the force acting from the indoor side to the outer surface side can be increased. Since the heads of screws and screws are exposed to the surface that is directly exposed to rainwater and direct sunlight, there are problems with durability and the aesthetics given to the viewer are impaired, and the design effect is inferior. Since the head was exposed, rust and discoloration were likely to occur, and the rust and discoloration more markedly exhibited the above-mentioned defects. Further, there is also a drawback that rainwater easily enters the indoor side due to a capillary phenomenon from the overlapping portions on both sides of the adjacent siding, resulting in poor water leakage resistance.

In order to construct the outer wall by the latter spandrel, one side edge of the spandrel having the engagement piece receiver 9c formed in one concave shape is fixed to the furring strip 7 of the building. After inserting the engaging piece 9d of one plate formed on the side edge of the spandrel fixed to the furring strip 7 of the building into the joint piece receiver 9c, the opposite side of the engaging piece 9d is inserted. The operation of fixing the side edge on which the concave engagement piece receiver 9c is formed to the furring strip material 7 of the building by tapping screws is sequentially repeated laterally. In order to form the outer wall by this spandrel, the engagement piece receivers 9c formed on the side edges of the adjacent spandrel are fixed to the furring strip material 7 of the building by tapping screws or the like, and the fixed engagement piece receivers 9c are fixed to the fixed engagement piece receivers 9c. Since it can be fixed to the furring strip 7 of the building by a simple operation of inserting the engaging piece 9d formed on the side edge of the next spandrel, it can be installed in a short time, and the tapping screw head Since it is not exposed to the surface of the outer wall, the design effect can be fully exerted, but if the back side of the spandrel is not filled with a heat insulating material such as foamed resin to enhance the heat insulating effect, the wind When negative pressure due to, for example, a force acts from the indoor side to the outer surface side, the spandrel bends and the engaging piece is received.
There was a fatal drawback that the engaging piece 9d just inserted into the 9c would easily come off from the engaging piece receiver 9c.

That is, although the spandrel may be filled with a heat insulating material on its back side, the spandrel used to construct the wall surface of a factory is usually formed by bending a single metal plate. It has a simple structure that is only shown in FIG. 6, and as shown in FIG. 6, only one flat edge, which is the engaging piece 9d, is inserted into the engaging piece receiver 9c. When a force acts from the inner side to the outer surface side, the center portion between the engaging piece receiver 9c and the engaging piece 9d is easily deformed so as to bulge outward, so that the engaging piece 9d easily comes off from the engaging piece receiver 9c. There was a drawback that it would end up. Furthermore, when the force from the indoor side to the outer surface side is repeatedly applied by the wind or the like, the engaging piece 9d is received by the engaging piece receiving part.
There is also a drawback that rainwater enters the indoor side through this engaging portion by pulsating in 9c and the leakage resistance is poor.

When the fitting portion 4b of the engagement piece 4 of the outer wall material for use 1 is inserted and engaged, a desired space 5 that does not communicate with the opening 3c is provided between the engagement piece receiver 3 and the engagement piece 4. It is formed into a shape that can be formed,
Various aspects will be described while explaining aspects such as the embodiments shown in the drawings.

In the embodiment shown in FIGS. 2 and 3, an engaging piece receiver 3 formed by bending over the entire length of one side edge portion of the wall surface body 2 is opened at the side surface of the wall surface body 2. The support portion 3a formed at the position of the wall surface main body 2 side of the entrance of the opening 3c of the groove-shaped recess 3b in which the portion 3c is open is also used as the ridge portion 3d which is convex toward the groove-shaped recess 3b. In the embodiment shown in FIG. 3, the groove 3 is formed continuously on the side surface of the wall surface main body 2 and is continuous with the support portion 3a formed at the position of the wall surface main body 2 side of the opening 3c entrance of the groove-shaped recess 3b. The ridge portion 3d which is convex on the side of the concave portion 3b is formed separately. In such a structure, the support surface 3aa of the support portion 3a may be formed to be inclined with respect to the wall surface main body 2, but if it is formed in parallel with the wall surface main body 2 as in the illustrated embodiment, pressure such as wind pressure is generated. Accordingly, when the engaging piece 4 is laterally displaced, a step is not generated on the surface of the wall surface main body 2 of the adjacent vertically-extending building outer wall material 1, which is preferable.
Further, in the embodiment shown in FIGS. 2 and 3, the bottom portion 3ba of the groove-shaped recess 3b is parallel to the wall surface body 2, but the furring strip 7 of the building.
It is configured so as not to come into direct contact with or through the reinforcing material 6 described later, but as shown in FIG. 4, directly to the furring strip material 7 of the building as in the embodiment or via the reinforcing material 6 described later. It may be shared with the bottom flat plate portion 3e parallel to the wall surface body 2 so as to abut.

In each of the illustrated embodiments, an engaging piece 4 formed by bending the other side edge portion of the wall surface body 2 over its entire length is first located near the wall surface body 2. After the supported surface 4aa of the supported portion 4a supported by the supporting surface 3aa is formed at a position corresponding to the supporting surface 3aa of the supporting portion 3a of the engaging piece receiver 3, the groove-shaped recess of the engaging piece receiver 3 is formed. A supporting flat plate portion 4bb is formed which abuts on the bottom flat plate portion 3e of the engagement piece receiver 3 or the bottom portion 3ba of the groove-shaped recess 3b through the face plate reaching the bottom portion 3ba of the 3b or the bottom flat plate portion 3e. Locking part that is locked to the ridge 3d
In this embodiment, the face plate on the edge side up to 4ba is formed, and the face plate on the edge side of the supporting flat plate portion 4bb is bent toward the outer side on the edge side in the middle thereof.

The engagement piece receiver 3 thus formed and the engagement piece 4 formed on the opposite side edge portion sandwiching the wall surface main body 2 are shaped and dimensioned as described above. It has a shape and dimensions corresponding to. That is, the bottom plate portion 3e is to be fixed next in the engagement piece receiver 3 of the vertical building outer wall material 1 which is fixed to the furring strip member 7 of the building by the tapping screw 8 or the like. When the engaging piece 4 of No. 1 is inserted, the engaging section which is on the edge side of the supporting flat plate section 4bb of the fitting section 4b of the engaging piece 4 and is engaged with the ridge 3d of the engaging piece receiver 3 4ba
Is formed into a shape capable of forming a desired space 5 between the engagement piece receiver 3 and the engagement piece 4 that does not communicate with the opening 3c, and the engagement piece 4 is a metal plate. Since it is formed by bending, the fitting portion 4b formed by the supporting flat plate portion 4bb and the face plate on the edge side of the supporting flat plate portion 4bb has a spring action, so that the fitting portion 4b is engaged. When it is inserted into the groove-shaped recess 3b of the one-sided receiver 3, the engaging portion 4ba at the end edge of the fitting portion 4b.
Are locked to the ridges 3d, and as a result, the space 5 is formed.

Here, the engagement piece receiver 3 and the engagement piece 4 are engaged with each other with the engagement piece 4 inserted into the engagement piece receiver 3 and engaged with each other. Since it is possible to prevent rattling, it is preferable to have a shape and size that are restricted in position and cannot move in a direction parallel to the bottom flat plate portion 3e of the engagement piece receiver 3.

In order to fix the vertical wall material for building 1 according to the present invention to the furring strip 7 of a building, a metal having a bending rigidity higher than that of the metal plate of the vertical wall material for building 1 is used. It is preferable to fix it to the furring strip member 7 of the building through a reinforcing member 6 made of a plate. As shown in FIG. 3, the reinforcing member 6 is used to form the groove shape of the engaging piece receiver 3 of the vertical building outer wall member 1. Since the outer surface side of the recessed portion 3b is fixed while being held, even if the groove-shaped recessed portion 3b is long so as to hold it over its entire length, only the portion corresponding to the furring strip 7 of the building It may be a short shape only for holding. When fixing through such a reinforcing member 6, as shown in FIG. 3, the locking piece 6a is attached to the reinforcing member 6,
Further, it is preferable that a reinforcing material locking recess 3f for locking the locking piece 6a of the reinforcing material 6 is formed on the outer surface of the engaging piece receiver 3 of the building exterior wall material 1 for upright construction. In this case, the outer surface side of the projection 3d of the engagement piece receiver 3 forms a reinforcing material locking recess 3f.

[0018]

In order to construct the outer wall by fixing the vertically-extended building outer wall material 1 according to the present invention to the furring strip material 7 of the building, the bottom flat plate of the engagement piece support 3 is first prepared. The portion 3e is fixed to the furring strip 7 of the building by tapping screws 8 or the like. At this time, as shown in FIG. 3, a reinforcing material 6 for holding the outer surface side of the groove-shaped recess 3b of the engaging piece receiver 3 is interposed. When fixed, it prevents the opening 3c of the groove-shaped recess 3b of the engagement piece receiver 3 from being deformed so as to open when a force is exerted from the indoor side to the outer surface side by the wind or the like, and the engagement once engaged It is preferable because the piece 4 can be completely prevented from coming off the engagement piece receiver 3.

In the case of fixing the vertically-extending building outer wall material 1 to the furring strip material 7 of the building through the reinforcing material 6, for example, the fitting piece receiver 3 is provided with the reinforcing material locking recess 3f (shown in the figure). In the embodiment, the protruding piece 3d is formed with an outer surface side of a portion for locking the locking portion 4ba of the engaging piece 4 and the locking piece for locking the reinforcing material 6 in the reinforcing material locking recess 3f. 6a is formed and further reinforcing material 6
Is a short shape, the reinforcing material 6 is fixed by the spring action of the vertical building outer wall material 1 and / or the reinforcing material 6 at an interval that matches the interval of the furring strips 7 of the building to be fixed in advance. After being attached to the building exterior wall material 1 for vertically extending, it is fixed to the furring strip material 7 of the building by tapping screws 8 or the like.

In this way, the groove-shaped recess 3b of the engaging piece receiver 3 of the vertically-extending building outer wall material 1 having the engaging piece receiver 3 side fixed to the furring strip member 7 of the building by the tapping screw 8 or the like is next described. The fitting portion 4b of the engaging piece 4 of the vertically-extending building outer wall material 1 adjacent to is inserted. Since the engagement piece receiver 3 and the engagement piece 4 are formed by bending a metal plate, the groove-shaped recess 3b of the engagement piece receiver 3 and the fitting portion 4b of the engagement piece 4 have a spring action, And the fitting portion of the engagement piece 4
A groove 3d is formed on the side of the opening 3c of the groove 3b of the engaging piece receiver 3 so that the groove 4b cannot be inserted unless it is deformed. The groove 3d and the groove 3d facing the groove 3d. Since the space L ₃ between the bottoms 3ba of the recesses 3b is formed narrower than the space L ₄ between the fitting portions 4b, the fitting portion 4b of the engaging piece 4 is elastically deformed and the engaging piece receiving portion 3 is formed.
When the engaging portion 4ba of the engaging piece 4 is inserted into the groove-like concave portion 3b of the engaging piece 4 and passes through the protrusion 3d of the engaging piece receiver 3, the fitting portion of the engaging piece 4 is inserted.
The supporting flat plate portion 4bb of 4b is the bottom portion 3 of the groove-shaped recess 3b of the engaging piece receiver 3.
The fitting portion 4b of the engagement piece 4 presses the groove-shaped recess 3b of the engagement piece receiver 3 by a spring action while being in contact with and supported by the ba. In this state, the supported surface of the supported portion 4a of the engaging piece 4
4aa is in contact with and supported by the support surface 3aa of the support portion 3a of the engagement piece receiver 3.

Here, for example, as in the illustrated embodiment, the engagement piece 4 is inserted into the engagement piece receiver 3 and engaged with the engagement piece 4 so that the engagement piece 4 is received in the engagement piece receiver 3. When the shape and size are regulated such that they cannot move in a direction parallel to the bottom flat plate portion 3e of the engagement piece 3, the fitting portion 4b of the engagement piece 4 is inserted into the groove-shaped recess 3b of the engagement piece receiver 3. The outer wall material 1 for vertical construction can be positioned more reliably only by performing the above.

In this way, it is next adjoined in the groove-shaped recess 3b of the engaging piece receiver 3 of the vertical building outer wall material 1 already fixed to the furring strip material 7 of the building by the tapping screw 8 or the like. As described above, the fitting portion 4b of the engagement piece 4 of the building exterior wall material 1 for vertically extending is inserted to insert the engagement piece 4 and the engagement piece receiver 3 formed on the opposite side with the wall surface body 2 in between. In other words, in the case of fixing the engagement piece receiver 3 to the furring strip 7 through the stiffener 6, the stiffener 6 is attached to a predetermined position that matches the distance between the furring strips 7 of the building, and the tapping screw 8 is installed later. The engaging piece receiver 3 and the reinforcing member 6 are fixed to the furring strip 7 of the building by tapping screws 8 or the like when the reinforcing member 6 is not interposed.

Such an operation is repeated laterally at a position where the outer wall of the building is to be formed, to form the outer wall. Thus, the vertically-extended building outer wall material 1 according to the present invention, which is fixed to form the outer wall of the building, is vertically stretched when a force acts from the indoor side to the outer surface side or from the outer surface side to the indoor side due to wind or the like. Although the outer wall material for construction 1 tries to bend so that its entire width becomes narrower, the protruding portion 3d of the engaging piece receiver 3 is engaged with the engaging portion 4ba of the engaging piece 4.
Is locked, it is possible to prevent the engagement piece 4 from coming off from the engagement piece receiver 3. Therefore, the once-fixed vertical outer wall material 1 for construction is attached to the tapping screw 8 at one side edge portion of the wall body 2.
As a result, the state of being fixed to the furring strip 7 of the building and being firmly fixed to the engaging piece receiver 3 of the adjacent outer wall material 1 for vertically extending construction at the other side edge is maintained.

Furthermore, since the engaging piece 4 has a spring action when the vertical building outer wall material 1 tries to bend so that its entire width becomes narrow, the adjacent vertical building outer wall material 1 has a spring action. Although a step is to be formed on the wall surface body 2 of No. 1, the supporting portion 3a of the engaging piece receiver 3 and the supported portion 4a of the engaging piece 4 formed in the vicinity of each wall surface body 2 support surface 3aa. Since the supported surface 4aa is supported by abutting on the support surface 3aa of the support portion 3a, the supported portion 4a is supported by the support surface 3aa of the support portion 3a regardless of whether the force acts from the indoor side to the outer surface side or from the outer surface side to the indoor side. The wall surface body 2 of the vertically-extending building exterior wall material 1 that is adjacent to the supported surface 4aa of the
There is no difference in level.

Rainwater penetrates into the portions of the vertically extending architectural outer wall material 1 between the engaging piece receivers 3 and 4 which are engaged with each other, and the inner surface of the engaging piece receiver 3 and the engaging piece 4 are engaged. Even if rainwater invades between the outer surface of the engagement piece 4 and the outer surface of the engagement piece 4, the engagement piece receiver 3 and the engagement piece 4
Since the space 5 that does not communicate with the opening 3c is formed between the and, the invading rainwater flows down along the space 5 and the infiltration of rainwater into the indoor side is prevented.

Furthermore, the building exterior wall material 1 for vertical extension is provided by wind or the like.
Even if the force from the indoor side to the outer surface side is repeatedly applied, the engagement piece receiver 3 and the engagement piece 4 are caused by the spring action to form the groove-shaped recess 3b of the engagement piece receiver 3 and the fitting portion 4b of the engagement piece 4. Since the contact state is always maintained, this portion does not act like a pump, and in combination with the above action, intrusion of rainwater is surely prevented.

[0027]

As described above in detail, the vertical building outer wall material according to the present invention is used for the engagement piece receiver of the vertical building outer wall material which is already fixed to the furring strip of the building. It can be positioned only by engaging the engaging piece of the vertically-extending building outer wall material that is fixed adjacent to the vertically-extending building outer wall material, and the fixing work by tapping screws, etc. Since it is only necessary to perform on one side edge of the exterior wall material for stretchable construction, it is possible to construct easily and in a short time,
In addition to workability during such construction, it has various effects as listed below when it is fixed to the furring material of a building to form an outer wall, and its industrial value is extremely large. It is a thing.

In a state where the outer wall of the building is formed, an opening of the engaging piece receiver and another space are formed on the inner surface of the engaging piece receiver of the vertically-extending building outer wall material that is fixed adjacent to each other. Therefore, the infiltration of rainwater due to the capillary phenomenon is prevented and the water leakage resistance is excellent.

Since the fitting portion of the engagement piece is fitted into the groove-shaped recess of the engagement piece receiver by the spring action, even if the wall surface body may flutter during wind and rain, the inner surface of the engagement piece receiver and the engagement piece The state of contact with the outer surface is maintained, rainwater is completely prevented from entering without causing the action of the pump, and in addition to the above-mentioned effect, it is very excellent in water leakage resistance.

When the outer wall is fixed by being fixed to the furring strip of a building, the wall body is less likely to bend, and therefore has excellent wind pressure resistance. Furthermore, the reinforcement that holds the outer surface side of the groove-shaped recess of the engaging piece receiver is used. When fixed via a member, the opening of the groove-shaped recess of the engaging piece receiver is prevented from being deformed so as to open when a force is exerted from the indoor side to the outer surface side by the wind or the like, and the engagement once engaged. It is possible to completely prevent the joint piece from coming off the engagement piece receiver.

Since the head of the tapping screw or the like for fixing to the outer wall material of the building is not exposed to the outer surface side, the design effect that the outer wall material for upright construction has is not impaired and the design effect is excellent. Further, even in a bad environment where wind pressure or the like acts, there is no step on the wall surface body of the adjacent building exterior wall material for vertical use, so that the overall design of the wall surface is not impaired and the design is maintained. It is very effective.
