Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a structure in which the middle of a wide construction board is fixed with bolts, but the bolts are not exposed to the outside, and the appearance is extremely elegant. The present invention relates to an intermediate attachment structure for an envelope that can increase the durability of the bolt.

[Conventional technology and issues]

The applicant has already conducted various research and development on an outer enclosure such as a roof or wall which is constructed by fitting adjacent architectural boards together from the viewpoint of good workability. By the way, if the width of the construction board is narrow, the strength of the middle part can be almost ensured, but when constructing an outer enclosure such as a roof or wall using the narrow construction board, the mating part may be damaged. Not only does the number of fittings and installation become troublesome, but also the ratio of the working width of the building board itself is small, resulting in the inconvenience that the construction cost of the enclosure is relatively high. Therefore, if the width of the construction board is made wider to increase the working width ratio, then when strong wind pressure (negative pressure) is applied, the middle part becomes particularly weak and the plate rattle phenomenon occurs. Ta. Then, if the middle part of the construction board is fixed with bolts, etc., the bolts will be exposed, and the bolts will corrode early, which will not only deteriorate the appearance, but also reduce the durability of the bolts. There were drawbacks such as rainwater infiltrating through the bolts.

[Means to solve the problem]

Therefore, the inventor worked diligently to eliminate the above-mentioned drawbacks.
As a result of repeated research, the present invention has been developed by providing two opposing bulging strips in the middle of the main plate, and using a groove between the two bulging strips,
A construction board with engaging parts formed on both bulging strips is placed on a structural material such as a main building, the bottom of the groove is fixed to the structural material with bolts, and the cap material having the engaging parts is attached to the structural material such as a main building. By fitting between the bulging strips facing each other and engaging the engaging portion with the engaged portion, even if the bolt is fixed in the middle of a wide construction board, the bolt will The bolt is not exposed to the outside, has an extremely elegant appearance, increases the durability of the bolt, and has good watertightness (rain protection), eliminating the above-mentioned drawbacks.

In particular, when constructing it as a wall, the longitudinal direction of the architectural board A may be vertical (see FIG. 9) or horizontal.

〔Effect of the invention〕

In the present invention, two opposing bulging strips 2, 2 are provided in the middle of the main plate 1, a groove 3 is formed between the two bulging strips 2, 2, and a locked portion 2a is provided between the two bulging strips 2, 2. ,2
A building board A with a formed thereon is placed on a structural member 8 such as a main building, and the bottom surface of the groove 3 is fixed to the structural member 8 with bolts to form a cap material B having engaging parts 7a, 7a.
is fitted between the opposing bulging strips 2, 2 to connect the engaging portions 7a, 7a and the engaged portions 2a, 2a.
By engaging with the bolts, firstly, even if the bolts 9 are fixed, the bolts 9 are not exposed to the outside, resulting in an extremely elegant appearance, and secondly, the durability of the bolts 9 is increased. Thirdly, watertightness (rainproofing) can be improved, and fourthly, the cap material B can be firmly fixed.

To explain the effect in detail, the bolt 9 fixing the groove 3 with the cap material B and the groove 3
is coated, giving it an extremely elegant appearance. Furthermore, the bolt 9 is not exposed to rainwater, and rainwater is less likely to enter from there, resulting in good watertightness (rain closure), and the bolt 9 etc. are less likely to corrode. The durability can be significantly improved. As a result, long-term quality assurance of the outer envelope can be ensured. This is an extremely effective effect in terms of maintenance and management. In particular, those with a wall structure can provide good watertightness (rain protection) and durability.

Further, in the present invention, the cap material B having the engaging portions 7a, 7a is fitted between the opposing bulging strips 2, 2, so that the engaging portions 7a, 7a and the engaged portions 2a, 2a are connected to each other. By engaging with the cap material B, the cap material B will not easily come off due to wind pressure or the like, and the cap material B can be firmly attached. In the present invention, the construction plate A for fitting is made wide in order to increase the working width ratio, and the bottom surface of the groove 3 in the middle of the main plate 1 is fixed with bolts 9, so that strong wind pressure (negative pressure)
The strength can be made sufficient even when the stress is applied, and the occurrence of plate ringing phenomenon can be prevented. When constructing an outer enclosure such as a wall or roof using wide construction board A with a high working width ratio in this way, there are fewer mating points, and the mating and installation work can be done easily and quickly. The construction cost of the outer enclosure can be reduced.
