Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an outer enclosure connecting structure for joining and connecting outer enclosures having alternating peaks and valleys.

[0002]

2. Description of the Related Art An envelope is formed by bending a thin steel plate having an arbitrary length so as to have peaks and valleys alternately. This outer enclosure connects adjacent outer enclosures to each other and is used as a roof material or a wall material.

When connecting adjacent outer enclosures, the outer enclosures are connected to each other by bolts, or the ends of the outer enclosures are provided with a seam and fastened with a suspender, and the seam is compacted and connected. Alternatively, the end portions are fitted with a cap to be connected to each other to connect the adjacent outer enclosures.

[0004]

[Problems to be Solved by the Invention] When the outer enclosure is connected with a bolt, the surface of the outer enclosure is easily corroded because it is liable to be rusted by the bolt and must be repaired regularly. The repair took time and money.

When a seam is provided at the end portion of the outer enclosure and the seam is compacted and connected, the seam is compacted by a seaming machine, but the seam as shown in FIG. When hardening, the angle at which the seams are bent becomes large, and spring backs etc. occur in the seams only in the left and right directions, so it is not possible to tighten them well, so it is necessary to tighten in the up and down directions as well. The structure of the machine is complicated and heavy. For this reason, there is a problem that the work becomes difficult when the seam clamp is moved, and there is a danger that the work is performed at a high place.

When the end portions of the outer envelope are fitted with a cap, the hanger fixed to the tight frame and the outer envelope must be fitted with the cap, as shown in FIG. Since an enclosure, a hanging member, and a cap are further required, the number of parts is larger than when connecting with bolts and when tightening the seams for connection. Also,
The cap must be molded together with the envelope, and in this case, since the thin steel plate was cut to match the width of the cap and then molded, the time and cost required for construction are doubled, and the problem is that construction is time consuming. there were.

In order to solve these problems, as shown in FIG. 6, the outer seam 2 provided at the end of the mountain portion 10 of one outer envelope 1 and the mountain portion of the other outer envelope 1 are provided. At the same time as the inner side provided at the end is engaged with the seam 6, the mountain portion 10 of the outer envelope 1 is engaged.
The engaging portion 9 provided at any position from the
There is a proposal to engage and connect with the engaging protrusion 13 provided on the tight frame 12. In this proposal, when connecting the outer enclosures 1 to each other, the outer enclosures 1 to be newly connected can be connected to each other simply by pressing the outer enclosure 1 from a direction perpendicular to the already provided outer enclosure 1. .

However, when connecting the outer enclosures 1 to each other,
The newly connected outer enclosure 1 is pressed against the already provided outer enclosure 1 from the vertical direction. However, with respect to a portion where the tight frame 12 is present, the tight frame 12 serves as a support member and the outer enclosures 1 are connected to each other. Is securely connected, but as for the portion without the tight frame 12 as shown in FIG. 7, when pressing from the vertical direction, the outer side seam 2 pushes down the inner side seam 6 and the outer side seam 2 falls. The inner side is less likely to be engaged with the seam 6, and thus it has been extremely difficult to securely connect the outer enclosures 1 to each other.

Further, since the outer envelopes 1 are pressed from the vertical direction when they are connected to each other, the outer envelope 1 is bent slightly against the pressing force as shown in FIG. The outer envelope body 1 that was deformed when the engaging portion 9 of the outer envelope body 1 was engaged with the engaging convex portion 13 of the tight frame 12
Tries to return to its original shape, but it may return to its original shape only a little due to the thickness of the material of the outer envelope 1 or the hardness or softness of the material. There was a problem that the engagement becomes shallower when engaging with the engaging convex portion 13.

Further, in many cases, a heat insulating material or the like is attached to the back surface of the outer enclosure, and the thickness thereof depends on the material or the like. For example, polyfoam has a thickness of about 4 mm to 10 mm, as shown in FIG. In the configuration in which the outer enclosure is engaged, the size of the tight frame 12 takes into consideration the thickness of the heat insulating material or the like, but basically, it is almost determined based on the working width of the outer enclosure 1 and the like. It does not necessarily correspond to the thickness of heat insulating material. For this reason, when the engaging protrusions 13 of the tight frame 12 are engaged with the engaging portions 9 of the outer body 1 having the heat insulating material or the like attached thereto, rattling occurs when the thickness of the heat insulating material or the like used is small. There were problems such as being lost. .

In view of the above problems, the present invention makes it easy and reliable to engage the outer seam and the inner seam and the outer frame with the tight frame, and thus the outer frame and the outer frame are simple and reliable. An object of the present invention is to provide a connection structure for an outer enclosure that can be surely connected.

[0012]

Therefore, according to the present invention, the peaks and the troughs are alternately formed, and the outer seam is formed at the end of one mountain and the inner seam is formed at the end of the other mountain. An outer enclosure provided with one or more engaging portions at arbitrary positions between the crests and the troughs, the outer seam and the inner seam each standing substantially vertically from the mountain. The outer seam has a raised part, the outer seam has a folded part, and the outer seam of the newly connected outer shell is the inner seam of the existing outer shell. Vertically cover so that there is a gap between the rising parts of the outer part, and the outer part of the outer part and the inner part of the outer part of the part by bending the outer part of the outer part of the part by using a seam clamp so that the rising parts of the inner part are close to each other. Are engaged with the inner ridge, and the engaging portions provided on the outer envelope are engaged with the engaging protrusions provided on the tight frame so that the outer envelopes are connected to each other. It is obtained to be connected.

[0013]

The outer seam and the inner seam provided at the ends of the ridges are standing seams each having a rising part raised substantially vertically from the ridge, and the outer seam has a folding part. The outer casing of the outer enclosure to be newly connected is already covered by an existing inner casing of the outer casing, which is vertically covered so that there is a gap between the rising portions of the outer casing, the outer casing, and the inner casing. In order that the rising parts of the seam come close to each other, the outer seam is engaged with the inner seam by folding the outer seam in a vertical direction by a seam clamp.

The outer seam is constructed so as to have a relatively wide opening between the folding part and the rising part, and when the outer seam is covered on the inner seam, the inner seam is caused by this opening. The outer cold can be comfortably covered by the outer cold so that the outer cold does not push down the inner cold-filled enclosure. Then, after covering the inner seam with the outer seam, the outer seam and the folded part of the outer seam are bent by a seam clamp so that the rising parts of the inner seam come close to each other. At this time, as the rising portions approach each other, the outer seam moves so as to engage with the inner seam, so that the outer seam can surely engage with the inner seam.

Further, when the folded-down portion of the outer seam is bent by the seam tightener, the respective rising portions of the outer seam and the inner seam move toward each other. By this movement, the respective engaging portions of the existing outer enclosure and the newly connected outer enclosure move so as to engage with the engaging protrusions provided on the tight frame. The joint portion can be reliably engaged with the engagement portion of the tight frame. At this time, the movement of the engaging portion of the outer body that is engaged with the engaging convex portion provided on the tight frame is restricted by the engagement of the inner seam and the outer seam, and the inner part that is engaged is The outside and the outside are
Since the movement is restricted by the engagement between the engaging convex portion and the engaging portion, there is no rattling or disconnection of the outer enclosure after the connection, and the connection can be surely made, and stable use for a long period of time becomes possible.

Further, the folding machine for folding the folding portion of the outer side only bends the folding portion which is inclined downward so as to be in the vertical direction. If the folding angle is small, the folding machine can be bent. The structure of can be simplified and made lightweight. Therefore, a small number of operators are required when using the seam to connect the enclosures, and it is relatively safe and easy to install.

Reference numeral 1 is a valley portion formed on the outer envelope 1, 12 is a tight frame, and 13 is an engaging convex portion.

An embodiment of the present invention will be described. In this embodiment, when the outer envelopes 1 are connected to each other as shown in FIG. 1, the outer seam 2 provided at the end of one mountain portion 10 of the outer envelope 1 is inclined downward. Has a folding part (3), the outside of which is covered with a sea (2) and the inside of which is provided at the end of the mountain part (11) of the other outer casing (1) is covered with a seam (6), and the seam is folded down with a seam clamp. The outer frame 2 is engaged with the inner line 6, and the tight frame 12 is provided with an engaging part 9 provided at an arbitrary position between the peak 10 and the valley 11 of the outer envelope 1. The outer peripheral bodies 1 are connected to each other by engaging the engaged convex portions 13 thus formed.

As shown in FIG. 1, the outer envelope 1 has ridges 10 and valleys 11 alternately, and one end of one ridge 10 has an outer seam 2 and the other ridge 10 has an end. The inner side is provided with a breeze 6. Then, the engaging portion 9 is provided at an arbitrary position from the mountain portion 10 to the valley portion 11.

The outer edge 2 is one mountain portion 10 of the outer envelope 1.
It has a rising part 5 which is provided at the end of the ridge and which rises substantially vertically from the mountain part 10, and has a folding part 3 which is inclined downward and an engaging part 4. There is.
Further, it is configured to have a relatively wide opening portion between the folding portion 3 and the rising portion 5.

The inner recess 6 is the other mountain portion 10 of the outer envelope 1.
It has a rising portion 8 which is provided at the end portion of the ridge portion and is erected substantially vertically from the ridge portion 10, and has an engaging portion 7.

Next, the connection between the outer enclosures 1 will be described. First, as shown in FIG. 2A, as shown on the left side of the figure, the inside 1 of the already provided outer envelope 1 is set to the sea 6 and the outside 2 of the outer seam 2 is set above the outer envelope 1 to be newly connected. To do.
Next, as shown in FIG. 2B, the inner seam 6 and the outer seam 2
So that the inner side of the outer enclosure 1 that is newly connected to the engaging portion 7 of the sea 6 is in contact with the engaging portion 4 of the sea 2. At this time, the concave portion 9a of the engaging portion 9 of the outer envelope 1 comes to be slightly separated from the engaging convex portion 13 of the tight frame 12,
The tight frame 1 is the mountain portion 10 of the newly connected outer enclosure 1.
It comes in contact with the upper end of 2.

Although not shown, when the other engaging portion 9 of the newly connected outer casing 1 is engaged with the engaging convex portion 13 of the tight frame 12 and is pushed from the right lateral direction in the drawing, As shown in FIG. 2C, the rising portion 5 of the outer casing 1 to be newly connected is closer to the rising portion 8 of the sheath 6 on the inside of the already provided outer casing 1. . In this state, the folding down portion 3 which is inclined downward by the binding machine is bent in the vertical direction as shown in FIG. 2D, and the engaging portion 4 of the outside 2 is engaged with the engaging portion 7 of the inside 6. Let
The engaging portion 9 of the outer envelope 1 that is newly connected to the engaging protrusion 13 of the tight frame 12 is also engaged, and the outer envelopes 1 are connected to each other.

Also, as shown in FIG.
Rising part 5 and rising part 8 of the inside 6
In the state in which they are separated from each other, the folding-down portion 3 which is inclined downward by the binding machine is bent in the vertical direction, and the engaging portion 4 of the outer seam 2 and the engaging portion of the inner seam 6 are engaged as shown in FIG. It is also possible to connect the outer enclosures 1 to each other by engaging with the engaging projections 13 of the tight frame 12 and the engaging portions 9 of the outer enclosure 1 to be engaged with each other.

At this time, the rising portion 5 of the seam 2 on the outer side and the rising part 8 of the seam 6 on the inner side are separated from each other, but when the seam clamp is used, the outer envelope 1 already provided is Since the engaging portion 9 is substantially engaged with the engaging convex portion 13 of the tight frame 12, the inner rising portion 8 of the sea 6 is raised.
Are in almost the same position, but the outer enclosure 1 to be newly connected
The engaging portion 9 is the engaging convex portion 13 of the tight frame 12.
2C, the rising portion 5 of the outer seam 2 moves so as to approach the rising portion 8 of the seam 6 so that the inside of the already provided outer envelope 1 moves to the state shown in FIG. 2C. In this state, the folding lower barb 3 which is inclined downward by the fitting machine is bent vertically.

Although the outer enclosures 1 are connected to each other in this manner, the outer edge 2 has a relatively wide opening portion between the downwardly inclined folding portion 3 and the rising portion 5. Therefore, when the inner side cover 6 and the outer side cover 2 are covered, this opening portion allows the inner side cover 6 and the outer side cover 2 to be covered easily. Then, when the folding down portion 3 is bent by a crimping machine, the engaging portion 4 of the outer seam 2 moves so as to rotate substantially and engages with the engaging portion 7 of the inner seam 6 so that the engagement is ensured. Can be engaged.

Further, since the folded-down portion 3 bent by the seam presses the inner seam 6, the rising part 8 of the seam 6 is closer to the rising part 5 of the seam 2 on the outer side. Become. Therefore, the engaging portion 9 of the outer envelope body 1 already provided moves toward the engaging convex portion 13 of the tight frame 12, and the engaging portion 9 of the outer envelope body 1 to be newly connected is also tight frame. The engaging protrusions 12 move in the direction of the engaging protrusions 13, and the respective engagements become more reliable.

Furthermore, since the engaging portion 9 of the outer envelope 1 moves toward the engaging convex portion 13 of the tight frame 12 and engages securely, the heat insulating material or the like is attached to the back surface of the outer envelope 1. Even in this case, rattling does not occur between the engaging portion 9 of the outer envelope body 1 and the engaging convex portion 13 of the tight frame 12 after engaging due to the thickness of the heat insulating material or the like. .

The folding machine 3 which bends the folding portion 3 of the outer wind 2 may be arranged such that the folding portion 3 which is inclined downward is bent in the vertical direction, and the folding angle is small. Then, the structure of the seam clamp can be simplified and made lightweight. Therefore, when the outer side is folded, the folding part 3 of the wind 2 is bent, and then the outer side of the adjacent outer side is folded, the folding machine 3 is moved. Even in the case of local work, it is relatively safe and easy to construct.

As described above, when the outer enclosures 1 are connected to each other, the outer seam 2 having the folding portion 3 of the newly connected outer enclosures 1 is replaced with the outer enclosure 1 already provided. The inner side of the cover 6 is covered with a seam 6, and the folding part 3 is bent with a seam clamp so that the outer seaside 2 is engaged with the inner seam 6 and the engaging part 9 provided on the outer casing 1 is connected to the tight frame. Since the engaging protrusions 13 provided on the connector 12 are engaged and connected, the outer enclosures 1 can be connected easily and reliably.

At this time, as shown in FIG. 2D, the engaging portion 9 of the outer casing 1 engaged with the engaging convex portion 13 provided on the tight frame 12 has the inner side 6 and the outer side. The movement of the inner seam 6 and the outer seam 2 which are engaged is restricted by the engagement of the engaging convex portion 13 and the engaging portion 9, and therefore, the movement is restricted. Afterwards, rattling on the outer body 1,
There will be no disconnection, etc., and a reliable connection will be possible, enabling stable use over a long period of time.

Next, another embodiment of the present invention will be described. In this embodiment, when the outer envelopes 1 are connected to each other as shown in FIG. 3, the outer seam 2 provided at the end of one mountain portion 10 of the outer envelope 1 is connected to the mountain portion 10. It has a substantially parallel folding part 3 and a folding part 2a, the outer side of which is covered with the seam 2 and the inner side of the other envelope 1 which is provided at the end of the mountain part 11 is covered with the seam 6 and the seam. The folding down portion 3 is bent by a tightening machine, the outer side seam 2 is engaged with the inner side seam 6, and the engaging part 9 provided at an arbitrary position between the mountain part 10 and the valley part 11 of the outer envelope 1 is attached. , The engaging protrusions 13 provided on the tight frame 12 are engaged to connect the outer enclosures 1 to each other.

In this embodiment, the folding portion 2a is provided so that the folding portion 3 can be easily folded when the folding portion 3 of the outer shell 2 is folded by a crimping machine.

Next, the connection between the outer enclosures 1 will be described. The connection between the outer enclosures 1 of the present embodiment is almost the same as the connection between the outer enclosures 1 of the above-described embodiments. First, FIG. 3A
As shown on the left side of the figure, the inner envelope 1 is set to the inner side of the already provided outer envelope 1 and the outer envelope 2 is newly connected so that the outer side 2 is above it. Then cover the inner cold side 6 with the outer cold side 2 as shown in FIG. 3B.

Although not shown, when the other engaging portion 9 of the newly connected outer casing 1 is engaged with the engaging convex portion 13 of the tight frame 12 and is pushed from the right lateral direction in the drawing, As shown in FIG. 3C, the rising portion 5 of the outer casing 2 to be newly connected is closer to the rising portion 8 of the outer casing 1 on the inside. . In this state, the folding down portion 3 is bent by the seaming machine as shown in FIG. 3D, and the outside seam 2 is engaged with the inside seam 6. At this time, the engaging portion 9 of the outer envelope 1 that is newly connected to the engaging convex portion 13 of the tight frame 12 is also engaged.

Further, as in the case of the above-described embodiment, in the state shown in FIG. 3B, the folding down portion 3 is bent by a binding machine, and as shown in FIG. 6, the engaging portion 9 of the outer envelope 1 which is newly connected to the engaging convex portion 13 of the tight frame 12 can be engaged.

The outer enclosures 1 are connected to each other in this manner, but since the outer side is provided with the bent portion 2a on the seam 2, the outer side is bent when the folding part 3 of the seam 2 is folded by a caulking machine.
Since the folding-down portion 3 is easily bent, it is not necessary to increase the force of the crimping machine so much. Therefore, the structure of the crimping machine can be relatively simplified and lightweight.

The outer edge 2 of the embodiment described above has an opening portion between the rising portion 5 and the folding portion 3 as shown in FIGS. 1 and 3, but the opening portion is not limited to this. In addition, any structure may be used as long as it has an opening portion between the rising portion 5 and the folded portion 3.

The shape of the outer envelope 1 is also shown in FIGS.
In addition to the shape shown in FIG. 2, it is sufficient if the engaging portion 9 has one or more at any position between the ridge portion 10 and the valley portion 11, and also for the tight frame 12, the engaging convex portion 13 is the outside. It suffices if it is configured so that it can be engaged with the engaging portion 9 of the enclosure 1.

Further, the folding part 3 provided on the outside 2
1 may be inclined downward as shown in FIG. 1 or may be substantially parallel to the mountain portion 10 as shown in FIG. 3, but not limited to this, the inclined portion or the bent portion 2a may be formed. It suffices that the folding portion 3 is provided with a fold or the like so that the folding portion 3 can be easily bent by a crimping machine.

[0042]

As described above, in the connecting structure of the outer enclosure of the present invention, the outer seam having the folded-down portion of the outer enclosure to be newly connected to the inner seam of the already provided outer shell. Cover and fold the folding down part with a seam clamp, engage the outer seam with the inner seam, and engage the engaging part on the outer envelope with the engaging convex part on the tight frame. Since they are connected to each other, the outer enclosures can be easily and reliably connected to each other.

Further, when the outer enclosures are connected to each other, the outer joint has a relatively wide opening between the folded-down portion and the rising portion. When opening, this opening allows you to comfortably cover the inner and outer winds. Then, when the folding down portion is bent by the crimping machine, the engaging portion of the outer seam moves so as to rotate substantially and engages with the engaging portion of the inner seam so that the engaging portion can be securely engaged. it can. Therefore, when the outer envelopes are connected to each other, the outer envelopes can be connected to each other without pushing down the inner wind.

Further, when the outer envelopes are connected to each other, the engaging portions of the outer envelopes move toward the engaging protrusions of the tight frame to securely engage with each other. , Etc., even if they are attached, there is rattling or engagement between the engagement part of the outer enclosure and the engagement protrusion of the tight frame after engagement due to the thickness of the heat insulating material, etc. It does not become difficult, and when connecting, the envelope does not bend and deform, and even if it deforms, the amount of deformation is extremely small, so it does not bend like the conventional example shown in FIG. It is possible to solve various problems caused by the deformation.

As shown in the embodiment, when the folded portion of the outer seam is inclined downward, the seam tightener to be used is arranged such that the downwardly inclined folding portion is vertically inclined. Since it suffices to simply bend so that the bending angle is small, the structure of the seam clamp can be simplified and lightened. Therefore, when using the seam clamp to connect the outer enclosure, it is possible to use it relatively safely and easily.
