Description

[Detailed Description of the Invention] [Field of Industrial Application] 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 mounting structure for a construction board that can increase the durability of its bolts.

[Conventional technology and its problems]

Traditionally, construction boards for wall or roofing materials, etc.
There are various types. 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, there are many connection points. This not only makes the connection and installation work troublesome, but also causes the disadvantage that the ratio of the working width of the building board itself is small, and the construction cost of the enclosure becomes relatively high. Therefore, if we make the construction board wider to increase the working width ratio, this will result in strong wind pressure (negative pressure).
When this is added, the intermediate part generally becomes particularly weak, and the plate ringing phenomenon occurs, although this is also related to the plate thickness. Then, if the middle part of the construction board is fixed with bolts, etc., the bolts, etc. 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 present invention provides a structure in which a groove is formed in the middle of a construction board, a rising part is provided on at least one side of the bottom, and a hanger having protrusions facing outward from each other on the rising part is inserted into the groove. Then, the bottom of the hanger and the bottom piece of the groove are fixed to the structural material with bolts, and a long cap material with legs on both sides of the upper piece is fitted over the hanger, and both legs are attached. By clamping and fixing between the protrusion of the hanger and the side of the groove, the bolts are not exposed to the outside even in a structure where the middle of a wide construction board is fixed with bolts, resulting in an extremely elegant appearance. This makes it possible to increase the durability of the bolt, and also to improve watertightness (rain protection), thereby eliminating the above-mentioned drawbacks.

〔Example〕

The structure will be explained with reference to the drawings.

A is a metal construction board A that is long in the longitudinal direction or has an appropriate length, and has one or more (see drawings) U-shaped cross section (first 2, etc.), and the groove portion 2 has a substantially U-shaped cross section (see FIG. 3) with narrowed upper sides on both sides. That is, the groove portion 2 is formed by a bottom piece 2a and side portions 2b, 2b on both sides.

It is composed of In the case of this fitting type construction board A, the bottom piece 2a of the intermediate groove 2 and the main board 1 are configured to be equally planar. That is, bulging stripes are formed on both sides of the groove 2. Reference numeral B is a metal hanger having an appropriate length, and has a rising part 6 on at least one side of the bottom part 5, and protrusions 7, 7 facing outward from each other are provided on the rising part 6. . In the embodiment, as shown in FIGS. 1 to 3 and 7, rising portions 6, 6 are provided on both sides of the bottom portion 5, and ribs having a semicircular cross section are provided on the outer surfaces of both rising portions 6, 6.

A plurality of protrusions 7, 7... are provided. Furthermore, in another embodiment, as shown in FIG. 5, FIG. 6, and FIG. It is formed. C is a long metal cap material, and the top piece 8 and both legs 9, 9 have a gate-shaped cross section (see Figure 1, etc.), and a cross-section that is approximately gate-shaped with narrowed upper sides on both sides (Figure 3). , see FIG. 5).

The construction board A is placed on a structural member 10 such as a purlin or a rim so that it is perpendicular to it (including approximately perpendicular to it), and a hanger B is inserted and placed in the groove 2. The bottom part 5 of the hanger B is fixed together with the bottom piece 2a of the groove part 2 to the structural member 10 with a drill-shaped bolt 11, and the long cap material C is fitted onto the hanger B, and both legs 9, 9 to the protrusions 7 and 7 of the hanger B and the groove 2

They are superimposed on each other, and within the space between them, the hanger B is attached to the structural member 1 using drill-shaped bolts 12 in the same way as in the intermediate configuration.
0, the cap material C is fitted onto the hanger B, and its legs 9, 9 are attached to the protrusions 7, 7 of the hanger B.
and the hanging portions 3a, 4a of the connecting portions 3, 4, and repeat these steps one after another to construct an outer enclosure such as a wall or roof. In the case of a mating construction board A, as shown in FIG. The protruding strips 4d of No. 4 are fitted elastically, and these steps are repeated in order to construct an outer enclosure such as a wall or roof.

In particular, when constructing a wall, the longitudinal direction of the architectural board A may be vertical (see FIG. 6) or horizontal.

In the figure, reference numeral 13 denotes a substantially flat heat insulating material such as foamed synthetic resin or rock wool, which is attached to the bottom surface of the architectural board A as necessary (see the dotted line in Figure 11).
(See the dotted line in Figure 13).

〔Effect of the invention〕

In the present invention, a groove 2 is provided in the middle of the building board A.
, and a rising portion 6 is formed on at least one side of the bottom portion 5.
A hanger B having protrusions 7, 7 facing each other outward on the rising portion 6 is inserted into the groove 2, and the bottom 5 of the hanger B is attached to the bolt 11 together with the bottom piece 2a of the groove 2. A long cap material C, which is fixed to the structural member 10 and has legs 9, 9 on both sides of the upper piece 8, is fitted onto the hanger B.
By clamping and fixing between the protrusions 7, 7 and the side parts 2b, 2b of the groove 2, firstly, even if the bolts 11 are fixed, the bolts 11 are not exposed to the outside, and the appearance is improved. It is extremely elegant, secondly the durability of the bolt 11 can be increased, and thirdly the cap material C can be firmly fixed.

To explain this effect in detail, the cap material C covers the bolts 11 that fixed the hanger B and its groove 2, and the appearance of the middle part of the outer envelope can be made extremely elegant. Furthermore, the bolts 11 are not directly exposed to rainwater, making it difficult for rainwater to infiltrate from there, and when the bolts 11 are configured outside an outer enclosure such as a wall, good watertightness (rain closure) can be achieved. 11 etc. is less likely to corrode, and the durability of the bolt 11 can be significantly improved. As a result, long-term quality assurance of the outer envelope becomes possible. This is an extremely effective effect in terms of maintenance and management. Furthermore, durable enclosures such as walls or roofs have recently been in particular demand in the construction industry, and specifically, the current 3 to 5 year warranty has been extended to 10 to 20 years. The present invention can satisfy the requirements for guarantee durability.

In addition, in the present invention, while the cap material C is fitted onto the hanger B, its legs 9, 9 are placed between the protrusions 7, 7 of the hanger B and the side portions 2b, 2b of the groove 2. By clamping and fixing, the cap material C will not easily come off due to wind pressure, vibration, etc., and the cap material C can be firmly attached.Furthermore, it is easy to press it against the hanger B during installation. Can be installed with one touch.

Furthermore, in order to increase the ratio of the working width of the architectural board A, the width is made wider, and the groove 2 in the middle of the main board 1 is
Since the bottom piece 2a is fixed with bolts 11, it can have sufficient strength even when strong wind pressure (negative pressure) is applied, and it is possible to prevent the occurrence of plate rattle phenomenon. When constructing an enclosure such as a wall or roof using wide construction board A with a high working width ratio, there will be fewer connection points, and the connection and installation can be done easily and quickly. The construction cost of the enclosure can be reduced.
