Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a tightening enclosure that can be easily tightened, has excellent watertightness and strength, has good rust prevention, and can adjust material dimensional errors, etc. Regarding the fastening structure.

[Conventional technology and its problems]

BACKGROUND ART Conventionally, metal tiled stick enclosures such as walls or roofs have been constructed. This tightening structure (other than the part where the partial hanger is attached) is located at the inward apex a, a on both sides of the architectural board (groove board), as shown in solid line in Figure 17
Then, the hanging edges b, b on both sides of the cap material are folded back into a flat shape and crimped. Furthermore, the tightening portion is often bent downward as shown by the dotted line in FIG. In theory, watertight construction can be achieved with such tightening, but in reality, the inward apexes a, a of the architectural boards often undulate in the longitudinal direction, causing deformation and strain, and as a result, they are flat. Unless the folding and crimping process is performed strongly, a plurality of holes are formed between the inward apex a and the drooping edge b, where the capillary phenomenon acts, and rainwater easily enters the inside. In addition, in order to bend and press the sheet into a flat shape, a large amount of force is required especially when the thickness of the sheet is increased, and a manual tightening machine not only has poor work efficiency but also causes significant fatigue. In addition, even electric crimping machines require a relatively large drive source (motor), and in order to fold and crimp the board flat, it is necessary to install crimping rolls or crimping blades depending on the thickness of the plate. Nakatsuta. Furthermore, when folded flat and crimped, the folded part often becomes cracked.
This area had the disadvantage of being prone to corrosion and poor anti-corrosion treatment. Further, if the tip of the top part a becomes wide within the allowable dimensional error of the standard material, there is a problem in that it becomes difficult to fit a cap material, a partial hanger, or a through hanger.

[Means to solve the problem]

Therefore, the present invention forms vertical parts on both sides of the main plate, and forms a top part inward from the upper ends of both vertical parts,
A fastening construction board having an edge bent in an arc downward from the tip of the top part is installed at an appropriate interval, and a flat part is formed outward from both upper ends of the flat U-shaped part, A flat U-shaped portion of the cap material having a hanging edge from the outer ends of both flat portions is fitted between adjacent fastening construction boards, and the flat portion and the hanging edge are connected to the adjacent fastening. Fitted onto both opposing tops and both edges of the architectural board, at least the base side of the hanging edge is folded downward while forming an arc shape, and the flat part and the top are
Either the hanging edges are brought into close contact with each other, and an appropriate gap is formed between the edges and the top, or vertical sections are formed on both sides of the main plate, and the upper ends of both vertical sections are formed. A top part is formed further inward, and a construction board with an edge bent in an arc downward from the tip of the top part is installed at an appropriate interval, and the top part is extended outward from both upper ends of the U-shaped part. The U-shaped part of the hanging hanger with a horizontal edge formed on one side is fitted between adjacent fastening construction boards, and both horizontal edges are placed on both tops, and both upper ends of the flat U-shaped part are fitted. A flat part is formed further outward, and a flat U-shaped part of the cap material is formed with edges hanging down from the outer ends of the flat parts, and is fitted into the U-shaped part of the hanger, and the flat part , pass through both hanging edges and fit over both horizontal edges of the hanger and the opposing edges of the adjacent construction board, and fold downward while forming at least the base side of the hanging edge into an arc shape. , flat part, horizontal part, horizontal edge, top mutually,
By bringing the hanging edge and the edge into close contact with each other and forming an appropriate gap between the edge and the top,
By forming it into an arc shape and then folding it back, there is no need to fold it back into a flat shape and crimping it, making tightening easier with less force, making tightening with a manual tightening machine more efficient and less tiring, and The crimping machine can perform good crimping with a small drive source, and since it does not fold back and crimp in a flat shape, there is no need to worry about cracks in the material, and it has good rust prevention. The watertightness can be extremely ensured by making the parts close together and by forming the gap, and the permissible dimensional error of the standard material can be adjusted at the edges, so that there will be no inconvenience during construction, and the above-mentioned This is a solution to a problem.

〔Effect of the invention〕

First, the invention described in claim 1 (first claim)
invention), there are vertical parts 2, 2 on both sides of the main plate 1.
, apex portions 3, 3 are formed inwardly from the upper ends of the vertical portions 2, 2, and edges 4, 4 are formed that are bent in an arc downward from the tips of the apex portions 3, 3. Plates A and A are installed side by side with appropriate spacing, and the flat U
Flat parts 9, 9 are formed outward from both upper ends of the character-shaped part 8, and end edges 10,
The flat U-shaped portion 8 of the cap material C forming the cap material 10 is fitted between the adjacent fastening construction boards A, A, and the flat portions 9, 9 and the hanging edges 10, 10 are fitted between the adjacent Fitted into both the opposing top portions 3, 3, both end edges 4, 4 of the fastening construction plates A, A, and at least the hanging end edge 1
0 and 10 are folded downward while forming an arc shape, the flat part 9 and the top part 3 are brought into close contact with the hanging edge 10 and the end edge 4, respectively, and the edge 4 and the top part 3 are brought into close contact with each other. By forming an appropriate gap 12 in between, firstly, the tightening process can be made very easily, secondly, rust prevention can be improved, and thirdly, watertightness can be made perfect, and furthermore, Fourthly, it can be made stronger, and fifthly, it has many effects such as being able to adjust the dimensions of the material. These effects will be described later. By forming at least the hanging edge 10 into an arc shape and folding it back, the folding and crimping process required in the past to make it flat is no longer necessary, and it is generally possible to fold the metal plate into a flat shape. The largest force is required at the final stage, but forming an arc shape and folding it does not require such a large force and can be formed with a relatively small force, making it easy to use with a manual tightening machine. When performing the tightening process, it can be done more efficiently with less labor. Furthermore, with an electric tightening machine, sufficient tightening can be performed even with a small drive source, and work efficiency can be significantly improved. That is, in the present invention, it is possible to perform an extremely simple crimping process for folding and crimping the fabric into a flat shape.
Furthermore, since it is an arc-shaped folding and not a flat folding crimping, there is no need for a tightening roll or a tightening blade depending on the plate thickness, and the tightening can be performed using the same tightening roll, etc., resulting in good results. Not only is it easy to work with, but the tightening machine can also be configured easily. Furthermore, when folded flat and crimped, many cracks occurred at the folded parts, but when folded in an arc shape, there are almost no cracks, and corrosion can be prevented from there, making it possible to prevent rust. A good tightening structure can be achieved from the front. In addition, by bringing the flat part 9 and the top part 3 into close contact with each other, and by bringing the hanging edge 10 and the end edge 4 into close contact with each other, and by forming an appropriate gap part 12 between the end edge 4 and the top part 3, The gap 12 can prevent the capillary phenomenon of rainwater, and its close contact can eliminate any room for the capillary phenomenon to occur, and even if it is folded flat and crimped as in the past, it does not prevent the rain from closing. It almost completely eliminates the problem, and even without folding and crimping, it is possible to reliably block the intrusion of rainwater from the fastening part, resulting in rain closure (watertightness).
It can be made into an extremely excellent fastening structure. In addition, this resilient contact means that the hanging edge 10 of the flat portion 9 and the edge 4 of the top portion 3 are less likely to loosen due to wind pressure, vibration, etc., and the plate rattling phenomenon can be minimized. The structure can be made strong so that the fastening part does not come off easily.

By the way, conventional architectural boards (groove boards) for roofing with tile sticks
The strip-shaped standard material that becomes the base material for molding is
A tolerance dimension is allowed on the plus side, and when roll-forming is performed using this, the end of the construction board, that is, the inward apex a, is often formed with a wide width, making it difficult to use partial hangers or through hangers. It is often the case that construction is impossible due to the inability to fit the cap material, etc. In order to prevent this, the width of the standard material is cut with a slitter to the desired width without any errors. It was also possible to roll form the plate. In this point,
In the present invention, by providing the edge 4 bent in an arc downward from the tip of the top part 3, even if the width of the standard material becomes wide within the allowable range without cutting with a slitter, the width of the standard material can be maintained at the dotted line in Figure 2. As shown by the dotted line in Figure 10, it is formed only slightly in the area within the top 3, and the width of the top 3 when viewed from above is always constant, so that tightening can always be carried out suitably. The edges of the standard material are generally better rust-proofed than other parts, and as a result, the fastened building board A of the present invention itself can be made superior in terms of rust-prevention.

Next, in the invention described in claim 2 (second invention), the U-shaped portion 5b is added to the structure of the first invention.
Add a through hanger _B2 having horizontal edges 6b outward from both upper ends of the hanger B2, fit the U-shaped part 5b of the through hanger _B2 between the adjacent fastening construction boards A, Further, both horizontal edges 6b, 6b are placed on both top parts 3, 3, flat parts 9, 9 are formed outwardly from both upper ends of the flat U-shaped part 8, and the outer sides of both flat parts 9, 9 are It passes through the flat U-shaped part 8 of the cap material C, which has hanging edges 10, 10, and fits onto the U-shaped part 5b of the hanger _B2 , and both of its flat parts 9, 9 both hang down. The end edges 10, 10 are inserted through the horizontal edges 6b, 6b of the hanger _B2 and the opposing end edges 4, 4 of the adjacent construction boards A, A, and at least the base of the hanging edge 10 is fitted. Push back downward while forming the side into an arc shape, flat part 9 horizontal edge 6
b The top part 3 is brought into close contact with the hanging edge 10 and the end edge 4, respectively, and an appropriate gap 12 is formed between the edge 4 and the top part 3. There is a stringer B ₂ along the entire length of the locking part,
By increasing the section modulus of the clamping part, an extremely strong clamping structure can be achieved. Furthermore, fastening processing can be performed easily and quickly. Achieving good rust prevention. Ensure watertightness. Ability to adjust material dimensions. These effects are as follows.
This effect is substantially the same as that of the first invention.

Note that if the end edges 11, 11 are provided below the hanging edges 10, 10 of the cap material C and the end edges 11 are configured to tightly contact the vertical portion 2, the end edges 11, 10 can be fastened. A cavity is formed in the tightening part, which prevents capillary action and makes the tightening part more watertight.
