<First embodiment>
A first embodiment of a building exterior and a construction method for a building exterior to which the present invention is applied will be described below.
In the first embodiment, as an example, the building is a large-sized building having a skeleton of a steel rigid-frame structure and used for a factory, a warehouse, or the like.
An example of the building exterior is a roof covered with corrugated slate as a roofing material.

FIG. 1 is a schematic cross-sectional view showing a state before construction of a roof to be constructed in a first embodiment of a building exterior construction method to which the present invention is applied.
A roof 1 is constructed by having a purlin 10, a slate 20 and hook bolts 30. - 特許庁
The purlin 10 is provided on the upper part of the frame of the building, and is a member serving as a base to which a slate 20, which is a roof material, is attached.
As the purlin 10, for example, a steel C-shaped channel material can be used.
The purlin 10 is, for example, arranged parallel to the longitudinal direction of the ridge and eaves (not shown).
A plurality of purlins 10 are arranged in parallel while being dispersed in the running direction of the roof.
A groove 11 is formed along the longitudinal direction of the purlin 10 at an intermediate portion in the height direction of the side surface of the purlin 10 .
The groove portion 11 is a portion where the lower end portion (hook portion) of the hook bolt 30 is locked.

The slate 20, which is the existing exterior material of the present embodiment, is a roofing material (roofing material) attached on the purlin 10. As shown in FIG.
The slate 20 is formed, for example, by pressure-molding cement, which is the main raw material, and reinforcing fibers.
As an example, the slate 20 has a cross-sectional shape in which protrusions 21 protruding in the shape of ridges when viewed from above and recesses 22 recessed in the shape of grooves when viewed from above are repeatedly arranged at a predetermined pitch. It is a corrugated slate with
A bolt hole 23 into which the hook bolt 30 is inserted is provided at the top of some of the projections 21 .
For example, in the example of FIG. 1 , one bolt hole 23 is periodically provided for three protrusions 21 .

The hook bolt 30 is mechanical fastening means for fastening the slate 20 to the purlin 10 .
The hook bolt 30 is formed, for example, by bending a lower end portion of a steel wire rod into a hook shape and threading an upper half portion thereof.
The lower end of the hook bolt 30 is hooked (engaged) with the groove 11 of the purlin 10 .
An upper portion of the hook bolt 30 protrudes toward the upper surface of the slate 20 through the bolt hole 23 .
A nut 31 is fastened to the threaded portion of the hook bolt 30 .
A nut 31 is attached to the upper surface of the slate 20 via a washer 32 .

A construction method for the building exterior according to the first embodiment will be described below.
First, on the roof 1 described above, the support member 40 is attached from above the nut 31 and washer 32 of the hook bolt 30 .
FIG. 2 is a diagram showing a state in which a support member is attached to the roof of FIG. 1;
The support member 40 is a long joist-like member arranged along the longitudinal direction of the projection 21 to which the hook bolt 30 is attached in the slate 20 .
The support member 40 can be made of, for example, a metal-based material such as an aluminum-based alloy, a resin-based material, or a wood-based material subjected to waterproof and antiseptic treatment.

The support member 40 is configured by, for example, integrally forming a body portion 41, a seal member housing portion 42, a projecting portion 43, bolt holes 44, and the like.
In a cross-sectional shape (or end face shape) of the support member 40 cut along a plane orthogonal to the longitudinal direction, the main body 41 is formed in, for example, a rectangular shape.
The lower surface portion of the main body portion 41 is arranged to face the surface of the slate 20 with a gap therebetween while sandwiching the seal member 50 therebetween.
On the upper surface of the body portion 41, the edge portion of a discard form member 60, which will be described later, is placed.
The side surface of the main body 41 has a function of blocking the leakage of the filler from one space to the other when the filler is injected into the spaces on both sides of the support member 40 .

The sealing member accommodating portion 42 is formed by recessing the lower surface portion of the main body portion 41 into a groove shape having a rectangular cross section.
When the support member 40 is attached to the slate 20, the seal member 50 is accommodated in the seal member accommodating portion 42 in a compressed state.

The projecting portion 43 is a portion formed by projecting upward in a stepped manner from the central portion in the width direction of the upper surface portion of the main body portion 41 .
The projecting portion 43 extends over the entire length of the support member 40 along the longitudinal direction of the support member 40 .
The bolt hole 44 is a hole into which the hook bolt 30 is inserted, and is formed penetrating from the lower surface of the main body portion 41 to the upper surface of the projecting portion 43 .

The seal member 50 seals between the lower portion of the support member 40 and the upper surface portion of the slate 20 in a watertight state.
The seal member 50 is formed as an elongated member that extends along the longitudinal direction of the support member 40 and is made of an elastic material such as butyl rubber.
The seal member 50 is held inside the seal member accommodating portion 42 of the support member 40 while being compressed in the longitudinal direction of the hook bolt 30 .
The lower surface of the seal member 50 is in close contact with the upper surface of the slate 20 due to the elastic force of the seal member 50 itself.

Next, the temporary form members 60 are attached to the roof 1 via the supporting members 40 .
FIG. 3 is a diagram showing a state in which the temporary form members are attached to the roof of FIG.
In the first embodiment, the discarded formwork material 60 is a so-called discarded formwork that is left after the filler is filled and cured, and functions as a new roofing material (new exterior material/roofing material) after construction. It is something to do.

The temporary formwork material 60, which is the new exterior material of the present embodiment, can be made of, for example, a steel plate plated with an alloy of aluminum, zinc, and silicon.
The discard form member 60 is formed, for example, in the shape of a flat plate and provided across a pair of support members 40 adjacent to each other with a space therebetween.
That is, the temporary form member 60 is configured by joining a plurality of divided members, and the support members 40 are arranged along the joints of the plurality of members.
The edge portion of the temporary formwork 60 is placed on the upper surface portion of the main body portion 41 of the support member 40, other than the region where the projecting portion 43 is provided.
The projecting portion 43 of the support member 40 is sandwiched between the edges of the pair of discarded frame members 60 that are placed adjacent to each other.

The height of the protruding portion 43 protruding from the main body portion 41 can be made equal to the thickness of the temporary frame member 60, for example.
As a result, the upper surface portion of the projecting portion 43 and the upper surface portion of the temporary frame material 60 are arranged substantially on the same plane.
Here, if the pitch (repeating period) between the convex portions 21 and the concave portions 22 of the slate 20 and the interval at which the hook bolts 30 are provided are known, a discarded form member 60 having a predetermined size is prepared in advance. As a result, it becomes unnecessary to adjust (trimming) the width of the discarded formwork 60 on site.
The upper surface of the projecting portion 43 of the support member 40 is exposed above the roof 1 in a joint-like manner along the flow direction of the roof 1 while being sandwiched between the pair of temporary form members 60 . The upper surface may be painted for waterproofing or reinforcement, or may be covered with a cover (not shown).

The sacrificial formwork 60 is attached to the support member 40 using a nut 33 threaded onto the hook bolt 30 and a washer 34 sandwiched between the nut 33 and the sacrificial formwork 60 .
A space S is formed between the lower surface of the temporary form member 60 and the upper surface of the slate 20 .
In the roof 1, a plurality of spaces S (spaces S1, S2, S3, .

FIG. 4 is a diagram showing a state in which the roof of FIG. 3 is filled with a filler (building exterior of the first embodiment).
As the filler, for example, an expandable resin material having fluidity before curing can be used.
For example, as a filler, a resin foaming agent such as a polyurethane resin, a phenolic resin, or a mixture thereof can be used.
For example, a resin containing polyol or polypropylene glycol (PPG) as a main component can be used.

A phenolic resin, a main component of a phenolic resin containing a novolac thermoplastic resin as a main component, or a mixture thereof can also be used as the main component.
A cross-linking agent such as isocyanate is mixed with these main agents at a mixing ratio of approximately 1:1 to foam, and fillers, additives, etc. are added to obtain fillers.
Isocyanate is a kind of CFC-free foaming agent, and has the function of generating carbon dioxide gas by reaction with water and foaming materials.
When this filler is injected into the space S of the roof 1, it immediately starts foaming, and a filler layer 70 is formed in the space S in about several tens of seconds, for example.
In addition, in the space S, prior to the injection of the filler, a sheet-shaped member having functionality such as waterproofness, fire resistance, reinforcement, and shock resistance is installed, and this sheet-shaped member is used as the filler. It may be embedded inside the layer 70 .

In the first embodiment, a plurality of spaces S partitioned from each other by the support members 40 are formed along the eaves direction.
The filler can be injected into each space S (S1, S2, S3, . . . ) sequentially.
In addition, when the temporary formwork 60 is divided into a plurality of members along the flow direction of the roof 1, for example, the temporary formwork 60 is installed from the eaves side (lower side) to fill the space S. The injection of the agent, and then the placement of the upper discarding mold material 60 and the filling of the filler may be sequentially repeated.

Further, the filler may be injected, for example, from an injection port provided on the upper side in the flow direction of the roof 1 so that the filler flows down to the eaves side along the flow direction of the roof by its own weight. .
Further, when the dimension of the roof along the flow direction is relatively large, the filler is injected from the tip of the tube T while the tube T is inserted into the space S, and the filler is injected from the bottom of the space S. The tube T can be drawn upward as the region where the filler layer 70 is formed develops upward.
FIG. 5 is a diagram schematically showing an example of a filler injection method in the building exterior construction method of the first embodiment.
5(a) and 5(b) sequentially show the states of the tube T and the filler layer 70 during construction in chronological order.

The lower surface portion 81 is a portion that contacts the upper surface portion of the slate 20 .
The lower surface portion 81 is formed as an uneven surface that conforms to the shape of the convex portion 21 and the concave portion 22 of the slate 20 and substantially adheres thereto so that the filler does not leak out.
The upper surface portion 82 is a portion that abuts on the lower surface portion of the temporary formwork member 60 .
The upper surface portion 82 is formed in a planar shape so as to be in substantially close contact with the lower surface portion of the dummy formwork 60 so that the filler does not leak out.
The side surface portion 83 is a planar portion provided between the side edge portion of the lower surface portion 81 and the side edge portion of the upper surface portion 82 .
The side portion 83 can be arranged along a plane perpendicular to the direction of flow of the roof 1, for example, when the sealing member 80 is used.
One surface of the side surface portion 83 has a function of blocking the filler when filling the filler, and contacts the filler layer 70 after the filler hardens to form the filler layer 70 . .
The end surface portions 84 are planar portions provided at both ends in the eaves direction when the sealing member 80 is used.
The end face portions 84 provided at both ends of the sealing member 80 are in contact with the side surfaces of the main body portion 41 of the support member 40 facing each other with a gap therebetween, and have a function of preventing the filler from leaking out from between them. have
