Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements to surface structures such as roofs and external walls of buildings.

The explanation will be given below using a roof as an example. The inventor of this application previously filed Utility Application No. 56-144186 (Utility Model Application No. 58-48811).
Inner inner layer materials such as fireproof materials are laid on the supporting members that are the main building, and metal face plate mounting members that are rafters are placed on these inner layer materials orthogonally to the supporting members. A roof in which an outer inner layer material such as heat-insulating or sound-absorbing material is laid on the step formed on the face plate mounting member with a space between it and the inner inner layer material, and a roof plate, which is the face plate, is fixed on the face plate mounting member. is proposed.

However, with the roof proposed earlier by the applicant, it is difficult to change the thickness of the space between the inner and outer inner layer materials, and it is difficult to deal with unevenness or changes in the thickness of the inner inner layer materials. Since the face plate mounting member is required to have a stepped shape on the hat-shaped steel, there is a problem in that it becomes expensive.

The present invention solves the above-mentioned problems, and makes it easy to change the thickness of the space between both inner layer materials, and easily deal with non-uniformity or change in the thickness of the inner layer material in the lower part, that is, inside the building. The purpose of the present invention is to provide a surface structure for a building that has a large degree of freedom in design, is easy to assemble, and is inexpensive.

In order to achieve the above-mentioned object, the surface structure of a building according to the present invention fixes bolts protruding to the outside of the building to a metal support member, and uses an inner inner layer material laid on the support member as the support member. Clamp it from the inside and outside of the building with a retaining plate tightened to the bolt,
A metal face plate mounting member is arranged on the outside of the building of the inner inner layer material and is perpendicular to the support member through a space, and the face plate mounting member is tightened to the bolts with inner and outer nuts to connect the inner and outer parts of the building. The structure is characterized in that an outer inner layer material is placed on the face plate mounting member, and the face plate is placed on the outer side of the outer inner layer material and fixed to the face plate mounting member.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 and 2.

In FIGS. 1 and 2, reference numeral 1 denotes a purlin or support member made of C-shaped steel, and the support member 1 has a plurality of bolts 2 arranged in parallel, each passing through the upper wall 1a of the support member 1 from below. A nut 3 is tightened to fix the bolt 2 to the upper wall 1a so as to protrude upward. An inner inner layer material 4 made of a fire-resistant or fire-resistant, heat-insulating, and sound-absorbing plate material such as a wood wool board is laid on the support member 1, and extends through the inner inner layer material 4 of the bolt 2 and protrudes above these. A presser plate 5 having an appropriate planar shape is fastened to the portion, and the inner inner layer material 4 is clamped between the presser plate 5 and the upper wall 1a of the support member 1 from above and below.

A plurality of hat shaped steels 7a are connected to the support member 1 through a space 6 above the inner inner layer material 4 to form a heat insulating air layer and to conduct electrical wiring, gas piping, etc.
are arranged parallel to and perpendicular to. It goes without saying that, in addition to the air layer, the air layer formed by the space 6 can be filled with glass wool or an inner layer material if necessary.

Reference numeral 7 denotes a face plate mounting member, which is composed of a metal rafter, ie, a hat-shaped steel 7a, a nut tightening plate 7b, which covers an opening on the lower surface of the hat-shape, a bolt 7c, and a nut 7d. The nut tightening plate 7b is disposed at the lower part of the flange portion of the hat shape steel 7a, and both ends thereof extend in the left-right direction beyond the flange portion, and the nut tightening plate 7b is provided with the bolt 7c.
It is fastened and fixed to the flange portion of the hat shaped steel 7a with nuts 7d.

The upper end of the bolt 2 is inserted into the tightening plate 7b, and the tightening plate 7b is clamped from above and below by inner and outer nuts 8 and 9 which are tightened onto the bolt 2. An outer inner layer material 10 made of a plate material having at least one of heat insulation and sound absorption properties is laid on the flange of the hat shaped steel 7a of the face plate mounting member 7, and a roof plate, that is, a face plate made of a long plate, covers the outer inner layer material 10. 11 is fixed on the face plate mounting member 7 by appropriate means, and the face plate 11
The ends of the two are engaged with each other to form a horizontal roof.

In the roof of this embodiment configured as described above, the space 6 can be easily closed by changing the positions of the inner and outer nuts 8 and 9 tightened by the bolt 2 or by changing the length of the bolt 2. In addition to being able to change the thickness of the inner inner layer material 4 by changing the position of the retainer plate 5 that is tightened to the bolt 2, the degree of freedom in design is large and workability during assembly is improved. Good.

In addition, in this embodiment, the presser plate 5 does not necessarily need to be provided at the joint part of the inner inner layer material 4, so even if the thickness of the inner inner layer material 4 is uneven due to manufacturing errors, these can be easily removed. Support member 1 with presser plate 5
It can be reliably fixed to the upper wall 1a, and displacement of the inner inner layer material 4 due to wind blowing up from below can be reliably prevented.

FIG. 4 shows a second embodiment of the present invention, which differs from the first embodiment in that the left and right flanges 7e of the face plate mounting member 7 are connected to each other via inner and outer nuts 8, 9, nut tightening plates 7b, etc. It is formed so that the inner inner layer material 4 and the outer inner layer material 10 can be attached with a space 6 apart using bolts 2. In this case, compared to the case of one bolt, the force to absorb the load from the roof and the concentrated stress during blowing up becomes larger, and as a result, the inner layer material 4,
Even if 10 is shrunk or deformed due to long-term use, there is no problem with the mounting structure.

FIG. 5 is a front view showing a state in which the modified face plate mounting member 17 is fixed, and it is also possible to transform the face plate mounting member 7 into shapes shown in FIGS. 6A to 6F.

In FIGS. 4 and 5, the same members as those described in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted.

In this embodiment, the nut tightening plate 7b of the face plate mounting member 7 may be provided over the entire length of the hat-shaped steel 7a, or may be provided only on a portion in the longitudinal direction near the penetration portion of the bolt 2.

Furthermore, in the present invention, as shown in FIG.
The nut 9 can be omitted by welding the head 2a of the bolt 2 to the upper surface of the upper wall 1a of the support member 1, or by welding it to the lower surface and penetrating the upper wall.

Furthermore, when applied to a roof, the present invention is not limited to the horizontal roof of the embodiment described above, but may also be a vertical roof, and is not limited to roofs.
It can be applied to surface structures such as the outer walls of buildings.

As explained above, the surface structure of a building according to the present invention uses bolts fixed to a metal support member, and an inner inner layer material laid on the support member is secured to the support member and a holding plate fastened to the bolts. At the same time, the face plate mounting member placed on the outside of the structure of the supporting member is clamped by the inner and outer nuts tightened to the bolts, so by changing the positions of the inner and outer nuts, the inner layer The thickness of the space between the material and the outer inner layer material laid on the face plate mounting member can be easily changed, and by changing the position of the presser plate, the thickness of the inner inner layer material can be changed or uneven thickness can be changed. Since it can be easily adapted to various types of design, there is a large degree of freedom in design, and workability during assembly is good, and it also uses a special face plate mounting member such as a stepped hat section like the one proposed earlier by the applicant. Since it is not necessary, it has the effect of being able to provide it at a low cost.
