Description

[Detailed Description of the Invention] The present invention relates to a surface structure that constitutes the outer wall or roof surface of a building.

Conventionally, as a means of forming this type of planar structure, a hat-shaped metal rafter R is arranged on a metal main building P, as shown in FIG.
Then, fix the rafter R on the main building P via the band B with fixing tools V such as bolts and nuts, and then fix the rafter R on the main building P.
A structure is known in which a heat insulating material, a sound insulating material, etc. made of wood wool boards etc. are laid on both sides of the roof, and a roof board Y is further covered.

However, this structure has the disadvantage that it is prone to condensation due to the large number of metal joints, and it also poses safety problems for workers working at heights, as marking work is essential for positioning the rafters.

In view of these defects, the inventor first proposed
An improved idea was proposed as No. 58-480 (Utility Model Publication No. 59-106901), but according to this, as a result of the cuts at the corners of the inner layer members such as wood wool boards becoming deeper, the inner layer members would be difficult to transport during continuous transportation. However, the drawback remained that it was easily damaged during construction. Therefore, the present invention was devised to overcome these drawbacks, and it eliminates the need for marking work when positioning rafters, and
Prevents condensation that tends to occur on rafters, etc., and
The object of the present invention is to provide a surface structure that has a low degree of damage to inner layer members such as wood wool boards and is also excellent in appearance.

That is, in the present invention, a connecting member having flanges formed on both outer sides is installed and supported on a plurality of metal supporting members such as purlins so that the opening thereof faces toward the supporting member and perpendicular thereto, and the lower end A plate-shaped inner layer member having a notch at the corner and a groove at the center of the upper surface is provided, and this inner layer member is supported and laid on the outer end surface of the connecting member, and has a substantially square cross section. A construction in which the formed rafters are fitted into the grooves, the rafters are fixed to supporting members with fixing devices such as bolts and nuts, and face plates such as roof plates are fixed with the rafters' locking claws and hangers. It is a surface structure of an object.

7 is a fixing device such as a bolt or nut, and the third
As shown in the figure, the inner layer member 3 is inserted through the two grooves 4a, 4a of the rafter 4, and the rafter 4 and the support member 1 are fixed together.

Next, the formation order of the surface structures will be explained.

First, the inner layer member 3, which has been formed in advance to have a predetermined size and width, is laid on the support member 1 without marking. An isosceles triangular gap is formed at the joint of the installed inner layer members 3, 3, and the connecting member 2 is inserted from the front into this gap to reinforce the inner layer members 3 and protect the aesthetic appearance of the building. Also serves as Note that the order of laying the inner layer member 3 and the connecting member 2 may be reversed to that described above, or the inner layer member 3 and the connecting member 2 may be laid alternately. After that, the groove 3b of the inner layer member 3
Fit the rafter 4 into the groove 4a of the rafter 4.
The inner layer member 3 is firmly fixed to the support member 1 while being held between the fixing tools 7. And on this rafter 4 there is a hanger 5,
A face plate 10 such as a roof plate is attached together with roof members such as felt, waste board, joints, etc. (not shown).

7 to 9 show other embodiments of the inner layer member 3 and the connecting member 2, and the first embodiment is different from the first embodiment in that the inner layer member 3 has angle-shaped notches at both lower end corners. The structure is the same, except that the notch groove 3c is formed, and the cross-sectional shape of the connecting member 2 is approximately inverted U-shaped, and therefore, the parts are common to the first embodiment. are given the same reference numerals and their explanation will be omitted.

The present invention has the above-mentioned configuration, and the connecting member is installed and supported on the supporting member so that the opening faces the supporting member and is orthogonal to the supporting member.
An inner layer member with a groove on the upper surface having a notch at a corner is supported and laid on the outer end surface of the connecting member, and a rafter having a substantially square cross section with a locking claw is fitted into the groove, and the inner layer member By interposing it between the support member and the rafters and fixing it with a fixing device, the inner layer member is interposed between the roof surface and the support member such as the main building, and as a result, it is possible to cut off the phenomenon of condensation. Summer. In addition, since the position of the rafter can be specified simply by fitting it into the groove provided in the center of the top surface of the inner layer member, there is no need for marking work at high places when installing the rafter, and there is no need to position the rafter. This improves the safety of workers working at heights and improves work efficiency.

Furthermore, by making the shape of the rafters approximately square in cross section,
As a result, the inner layer member can be interposed and fixed to the support member using fixing devices such as bolts and nuts without using a band, etc., so the support member, connecting member, inner layer member, and rafter can be fixed in one piece. This makes it possible to provide a strong surface structure.

Furthermore, by forming the locking pawl along the longitudinal direction of the rafter, the rafter can be easily roll-formed, and has many excellent effects such as being able to be provided at a low cost.

In addition, in the present invention, it is preferable to use a connecting member that has a surface finish such as coloring on at least the lower surface, and even if it is a long one that intersects with many supporting members, it is possible to use a connecting member that is installed between two supporting members. The inner layer member and the outer layer member may be
Appropriate materials such as heat insulating materials, sound absorbing materials, or laminated products of these materials may be used, and in some cases, soft materials may be used for part of the thickness direction, and bolts may be fixed to supporting members by welding. The face plate of the roof plate or the like may be made of a suitable material and structure, such as a galvanized steel plate or an aluminum plate.

And, this invention is not limited to roofs,
It can also be applied to surface structures such as external walls of buildings by simply changing the surface plate material.
