Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a locking structure for a locking outer enclosure that has excellent workability, durability, and extremely good watertightness and strength properties.

BACKGROUND OF THE INVENTION Conventionally, metal enclosures such as roofs or walls have been constructed. This tightening structure (places other than where the hanger is attached)
As shown in Fig. 18, the hanging edge of the bent part on the other side of the adjacent construction board is attached downward to part m a of the bent part on one side of the construction board. It is folded flat and crimped. Theoretically, watertight construction can be achieved with such fastening, but in reality, the top part a of the fastened construction board often undulates in the longitudinal direction, causing deformation and distortion, so it cannot be flattened. If the folding and crimping process is not performed strongly, a plurality of small gaps are formed between the hanging edge of the top part (a), where capillary action acts, and rainwater easily enters the inside. Also,
Because the tightening edge has a undulating top a in the longitudinal direction, it is often exposed to rainwater, and the edge is particularly prone to corrosion, resulting in poor rust prevention treatment and halving its durability. Ta.

Therefore, the present invention forms a vertical part on the image side of the main plate, forms an upper part inward from the upper end of the one vertical part, and forms an edge bent in a folded shape downward from the inner end, The upper part of a vertical part of a construction board with a part hanging down from the outer end of the top part than the upper end of the other vertical part.

Fit the vertical part, top, and hanging part of the adjacent fastening construction board onto the edge, form the base side of the hanging part into an arc shape, and fold it downward to connect the top and top parts. The edge and the hanging part are brought into close contact with each other, an appropriate gap is formed between the upper part and the edge, and the upper part and the top part are formed in an oblique shape outwardly downward, or as described above. In the structure of the invention, the end of the hanging part is brought into contact with the corner point between the vertical part and the upper part of the front fastening construction board, and a suitable first part is placed between the upper part and the hanging part. In addition, in the configuration of the invention described above, an arcuate portion is formed that bulges outward in a mountain shape from the lower end of the drooping portion of the construction board, and the arcuate portion is The end may be brought into contact with the vertical part surface to form a second cavity, or, in the structure of the invention described above, a folded edge may be formed inward from the outer end of the arc-shaped part of the fastening construction board. , by abutting the folded edge against the vertical part surface to form a second cavity,

Fits into 4. After the subsequent processing, the board is laid in the same way as the folded plate type construction board A (see Figure 12). By installing the hanger at point B and constructing the above-mentioned locking structure, a locking outer enclosure such as a roof or a wall is constructed.

Next, the effects will be explained.

First, in the invention described in claim 1, vertical portions 2.2 are formed on both sides of the main plate 1, and an upper portion 3 is formed inwardly from the upper end of the vertical surface portion 2 on the negative side. A vertical part 2 for a fastening construction board having an edge 4 bent in a folded manner downward from the inner end, and a part 6 hanging down from the outer end of the top part 5 from the upper end of the other vertical part 2. The vertical part 2, top part 5, and hanging part 6 of the adjacent fastening construction board A are fitted onto the edge 4 of the upper part 3, and the base side of the hanging part 6 is formed into an arc shape, and then folded downward. The upper part 3 and the top part 6 are brought into close contact with each other, and the edge 4 and the hanging part 6 are brought into close contact with each other, and an appropriate gap 9 is formed between the upper part 3 and the end edge 4, and the top part 3 and the top part 5 of the upper part 3 are brought into close contact with each other. By forming it in a downwardly sloping shape, firstly, the locking workability is good, and secondly, the locking part can be rust-prevented, and long-term quality assurance is possible, making it extremely durable. Thirdly, watertightness (rain protection) can be improved, and fourthly, especially strength can be improved.

To explain the function and effect in detail, by forming the base side of the hanging portion 6 into an arc shape and folding it downward, there is no need for folding and crimping to make the metal plate into a flat shape, which was conventionally required. Folding into a flat shape requires the greatest force at the final stage, but simply folding into an arc shape does not require such a large force and can be folded with a relatively small force.
When tightening with a manual tightening machine, the tightening process can be done efficiently with less labor. In addition, with an electric tightening machine, even if the driving source is small, extremely efficient tightening processing can be achieved. Furthermore, by folding it in an arc shape, there are almost no cracks or the like at the folded part, and the entire fastened part has excellent corrosion resistance, and its durability can be maintained over a long period of time. In recent years, there has been a particular demand for fastened enclosures such as roofs that have excellent corrosion resistance and are durable. The present invention can satisfy the requirement for durability guaranteed for 10 to 20 years.

Further, by bringing the upper part 3 and the top part 5 into close contact with each other, and the edge 4 and the hanging part 6, it is possible to eliminate the room for capillary phenomenon to occur, and furthermore, the gap between the upper part 3 and the end edge 4 can be eliminated. The portion 9 can prevent capillary action, can block rainwater from entering from the tightening area, and can provide a tightening structure with good watertightness (rain closure).

In addition, the base side of the hanging portion 6 is formed into an arc shape and then folded downward to bring the upper portion 3 and the top portion 5 into close contact with each other, and the edge 4 and the hanging portion 6 are brought into close contact with each other, and the upper portion 3 and the top portion 5 are brought into close contact with each other. By slanting outward and downward, a large wind pressure (negative pressure) is applied to the fastening construction board A, lifting the main plate 1 of the fastening construction board A upward, and at the same time lifting the vertical part 2 of the fastening construction board A. Even if a downward pulling force is applied, the upper part 3 is difficult to shift downward, and the strength of the tightened part can be increased. Further, the present invention does not require camping material B, etc., and can be constructed at a relatively low cost with a simple configuration.

Next, in the invention set forth in claim 2, the end of the hanging portion 6 of the adjacent fastening building board A in the structure of the invention of claim 1 is connected to the front fastening building board A. Vertical part 2 and upper part 3
Firstly, the strength of the clamping part is further increased by making contact with the corner of the clamping part 2 and forming an appropriate first gap 10 between the upper part 2 and the hanging part 6. It is possible to create an extremely strong locking structure, and second, it is watertight (
It has the effect of making the weather better (rain cover).

To explain the function and effect in detail, the upper part 3 and the top part 5 are formed to be inclined outwardly and downward, and the end of the hanging part 6 is tied to the corner angle between the vertical part 2 of the construction board A and the upper part 3. Since the construction board A is placed in contact with the construction board A, a large wind pressure (negative pressure) is applied to the construction board A, lifting the main plate 1 of the construction board A upwards, and at the same time tensioning the vertical part 2 downward. Even if a pulling force is applied, the end of the hanging portion 6 will not touch the vertical portion 2 of the construction board A.
The vertical part 2 is kept in a pressed state by coming into contact with the corner part of the upper part 3, and the vertical part 2 can be prevented from shifting downward. Strength can be further increased.

In addition, the first cavity 10 can prevent the capillary phenomenon of rainwater, and can reliably block rainwater from entering from the tightening area, providing a tightening structure with excellent rain closure (watertightness). can.

The other configurations are the same as the invention of item 1, and similarly, the fastening workability is good, the rust prevention of the fastening part is good, and long-term quality assurance is possible, and it is extremely durable. The functions and effects of the invention, such as improved watertightness (rain protection) and the like, are the same as those of the invention described in item 1.

Next, in the invention set forth in claim 3, the hanging portion 6 of the fastening construction board A in the configuration of the invention set forth in claim 2 is
forming an arcuate portion 7 that bulges outward in a mountain shape from the lower end of the
The corner of the hanging portion 6 and the arcuate portion 7 is brought into contact with the corner of the vertical portion 2 and the upper part 3 of the front fastening construction board A, and the upper part 3 and the hanging part 6 are brought into contact with each other. By forming an appropriate first gap 10 between the arcuate portion 7 and forming a second gap 11 by bringing the end of the arcuate portion 7 into contact with the two vertical surfaces, the second gap 11 also prevents rainwater from flowing. Capillary action can be prevented, and a double structure can be formed with the first cavity 10 to block rainwater infiltration, thereby providing a structure with extremely excellent rain shutoff (watertightness). Also, since the end of the arcuate portion 7 was brought into contact with the two surfaces of the vertical portion, a large wind pressure (negative pressure) was applied to the fastening construction board A.
Even if a force is applied that lifts the main plate 1 upward and simultaneously pulls the vertical part 2 downward and inward (to the main plate 1 side), the lower position of the vertical part 2 will not be pressed. , it is possible to reinforce the strength of the vertical portion 2 and further increase the strength of the tightened portion. Furthermore, the presence of the arcuate portion 7 allows the finished end of the fastened construction board A to be neatly shaped without waving in the longitudinal direction, increasing the section modulus and making it stronger. The other configurations are the same as those of the second invention, and the same effects can be achieved.

Next, in the invention set forth in claim 4, a folded edge 8 is formed inwardly from the outer end of the arcuate portion 7 of the fastening construction board A in the configuration of the invention set forth in claim 3, By bringing the folded edge 8 into contact with the vertical portion 2 to form the second gap 11, firstly, rust prevention can be improved and a durable locking structure can be provided.

To explain the effects in detail, the corrosion of the fastening section generally begins at the end of the fastening, and the corrosion due to battery action (commonly known as ``electrocorrosion'') quickly spreads to the entire fastening area. However, when the folded edge 8 is in contact with the vertical part 2 of the fastening construction board A, the extreme end of the folded edge 8 is inside the arcuate part 7 and the vertical part 2. As a result, the ratio of exposure to rainwater is extremely small, and as a result, the edges of the construction board A can be constructed to be extremely resistant to corrosion, and the corrosion resistance of the construction board A as a whole can be improved, resulting in increased durability. Can maintain sex for a long time. The other configurations are the same as those in the third aspect of the invention, and the same effects can be achieved.
