Description

The present invention relates to a seat mounting bracket for mounting a seat, which is used in a temporary building.

For example, in order to dismantle a building or the like, a heavy machine such as a power shovel is used at the dismantling site to destroy the building, subdivide it, and separate and dispose of the waste generated by the destruction.
When such dismantling work is performed in the vicinity of, for example, a residential area, a hospital, a school, or the like, dust is likely to be scattered. Since the building to be demolished is usually an old building, dust containing substances unfavorable to health such as asbestos may be generated, and when the waste disposal site is to be demolished. May generate dust containing substances that are also unhealthy, such as dioxin. Especially when dust that is unfavorable to health is generated, the scattering of dust is likely to be regarded as a big problem by neighboring residents.
Also, demolition of buildings is accompanied by noise, which can cause problems with neighboring residents.

When performing some kind of work, such as the demolition work of a building, as one of the technologies to prevent the leakage of dust and noise generated by the work to the outside, it is subject to demolition by a temporary building. The technology of covering the entire building is adopted.
Such a temporary building is composed of, for example, aggregates such as columns and beams, and a sheet covering at least a part thereof. The sheet may be doubled to further emphasize the purpose of preventing dust and noise from leaking out.

Seat mounting brackets are used to secure the seat to a temporary building.
The seat to be attached to the seat mounting bracket is generally a long rectangle, and a thick portion formed by making the thickness of the portion thicker than that of the other portions over the entire length of both ends in the width direction thereof. It has. In many cases, the thick part is made by folding both ends in the width direction of the sheet, and a linear body (for example, a rope) having a certain thickness is placed in a hole extending over the entire length of both ends in the width direction of the sheet. Formed by
The seat mounting brackets are long, and in many cases, they are connected in the length direction so as to correspond to the length in the length direction of the seat, and the interval corresponding to the length in the width direction of the seat. Are used by arranging them in parallel with a space between them. The seat mounting bracket is also provided with locking grooves at both ends in the width direction for locking the ends in the width direction of the seat.
The locking groove is a groove into which a thick portion of the sheet can be inserted, and the width of the opening of the locking groove is made narrower than the width on the inner side thereof. The width of the opening of the locking groove is larger than the thickness of the sheet but smaller than the thickness of the thick portion. The thick portion of the sheet is inserted into a wide portion on the back side of the locking groove. Then, the thick portion to be removed from the locking groove interferes with the edge of the opening of the locking groove and cannot be removed, and as a result, the thick portion is locked in the locking groove.
The seat mounting bracket fixes the seat by locking the thick portions at both ends in the width direction of the seat with the opposing locking grooves of the adjacent seat mounting brackets.
On the other hand, seat mounting brackets are also used to fix the double seats to the temporary building. Such seat mounting brackets are used to fix an outer locking groove for fixing a seat located outside the temporary building and a seat located inside the temporary building at both ends in the width direction. It has a locking groove on the inside of. Thereby, according to the seat mounting bracket, the double seat can be fixed to the temporary building.

Patent No. 3927567

By the way, there are some points to be improved in the seat mounting bracket as described above. The point is that stormwater can get inside the temporary building. The above-mentioned seat mounting bracket is fixed so that the seat is fixed in an inclined state, for example, to the roof portion of a temporary building so that the longitudinal direction of the seat coincides with the maximum inclination line. , May be used in an inclined state. In such a case, the problem that rainwater gets into the temporary building is likely to occur.
The seat mounting bracket as described above fixes the seat in a state where the thick portions at both ends in the width direction of the seat are inserted into the locking grooves. Here, rainwater adhering to the outer surface of the sheet may enter the locking groove. Rainwater that has entered the locking groove may wrap around the thick portion of the sheet in the locking groove and leak to the inside of the sheet. In this way, stormwater enters the temporary building.
And this problem also occurs when the seat mounting bracket is for fixing the double seat. Of course, such a problem generally occurs in a temporary building using a sheet, and is not a problem peculiar to a temporary building used for dismantling a building.

An object of the present invention is to provide a technique for making it difficult for rainwater to enter the inside of a temporary building including a sheet as a component.

In order to solve the above-mentioned problems, the inventor of the present application proposes the following inventions.
According to the present invention, a sheet having a long rectangular shape and having a thick portion having a thickness thicker than other portions at both ends in the width direction is used as a temporary building, and the outer side and the inner side are doubled. It is a long sheet mounting bracket used for mounting in a state of being in the above position, and a plurality of seat mounting brackets are arranged in parallel so as to have an interval substantially corresponding to the width of the seat at the time of use.
Then, two seat mounting brackets of the present invention are provided on both sides of the long main body and the width direction of the main body over the entire length in the length direction of the main body along the length direction of the main body. The width of the opening is made larger than the thickness of the sheet and smaller than the thickness of the thick portion, and the locking groove is capable of inserting the thick portion inside the thick portion. , Is equipped. Further, one of the two locking grooves provided on one side in the width direction of the main body is an outer locking groove for mounting the outer sheet, and the other is an outer locking groove for mounting the inner sheet. It is an inner locking groove located inside the outer locking groove when used for mounting, and the outer locking groove is located outside the inner locking groove with respect to the main body. There is.
Such a seat mounting bracket adopts a configuration considerably similar to that of a conventional seat mounting bracket for mounting a double seat. The distinct difference from the conventional seat mounting bracket is that the outer locking groove is located outside the inner locking groove with respect to the main body.
Temporarily, two seat mounting brackets are arranged in parallel in the direction along the maximum inclination line in that part of the temporary building, and the opposite outer locking grooves of them are arranged in the width direction of the outer seat. The thick parts at both ends are locked as described in the background technology column, and the thick parts at both ends in the width direction of the inner sheet are described in the background technology column in the opposite inner locking grooves. It is assumed that it is locked as follows. If it rains in that state, the rain will fall on the entire surface of the outer sheet, so the rainwater near the center in the width direction of the sheet will flow down along the outer sheet, but the rainwater near both ends in the width direction of the sheet will be outside. It will get into the blind groove. Therefore, even when the seat mounting bracket of the present application is used, as described in the background technology column, rainwater that has fallen on the outer surface of the outer seat enters the outer locking groove and enters the outer locking groove. A phenomenon may occur in which the thick portion of the outer sheet wraps around to reach the inner surface side of the outer sheet, and then leaks out from the outer locking groove.
However, when the seat mounting bracket of the present application is used, the rainwater leaking from the outer locking groove to the inside of the outer seat drips toward the inner seat underneath, but the outer locking groove. Is located outside the inner locking groove with respect to the main body, so the position where rainwater drips is away from the inner locking groove, in other words, closer to the center in the width direction of the inner sheet. Therefore, the rainwater that has fallen at such a position will flow down on the inner sheet along the maximum inclination line, and is unlikely to enter the inner locking groove. As a result, the seat mounting bracket of the present application can prevent rainwater from entering the inside of a temporary building including the seat as a component.

At a position corresponding to the lower side of the outer locking groove when the opening is used, the rainwater leaking from the outer locking groove drips from the outer locking groove toward the outside of the inner locking groove. A guide protrusion may be provided to guide the leaked rainwater through the leaked rainwater.
As described above, since the outer locking groove in the seat mounting bracket of the present invention is located outside the inner locking groove with respect to the main body, the thick portion of the outer sheet is rotated toward the inner surface side of the outer sheet. The position where the rainwater that leaks from the outer locking groove after being filled in drips is away from the inner locking groove. This makes it difficult for rainwater to enter the inner locking groove, which is the reason why it is difficult for rainwater to enter the inside of the temporary building. Even if it is located, it cannot be said that there is a possibility that the rainwater leaking from the outer locking groove will travel through something in the seat mounting bracket and reach the inner locking groove. By providing the guide protrusion as described above on the seat mounting bracket, the above-mentioned effect of the seat mounting bracket of the present invention, that is, the effect that rainwater is less likely to enter the inside of the temporary building can be more reliably exhibited. Will be able to.
The shape and mounting position of the guide protrusions are not particularly limited as long as they can exert the above-mentioned effects. The guide protrusion may be present over the entire length of the seat mounting bracket in the length direction.

The inventor of the present application also proposes a seat set obtained by combining the above-mentioned seat and a seat mounting bracket as one form of the present invention. By using such a sheet set, it becomes possible to construct a temporary building in which rainwater does not easily enter.
An example sheet set is a long rectangular sheet having at least one sheet having a thick portion thicker than the other portions at both ends in the width direction, and the sheet being temporarily constructed. It is a long length used for attaching to an object in a double state of the outside and the inside, and when it is used, a plurality of pieces are arranged in parallel so as to have an interval substantially corresponding to the width of the sheet. It is a seat set including at least two seat mounting brackets used.
The seat mounting brackets in this seat set are two each on both sides of the long main body in the width direction of the main body and over the entire length in the length direction of the main body along the length direction of the main body. A locking groove is provided so that the width of the opening is larger than the thickness of the sheet and smaller than the thickness of the thick portion, and the thick portion can be inserted into the locking groove. And have. Further, in the seat mounting bracket, one of the two locking grooves provided on one side in the width direction of the main body is an outer locking groove for mounting the outer seat, and the other is an outer locking groove. It is an inner locking groove located inside the outer locking groove when used for mounting the inner sheet, and the outer locking groove is located outside the inner locking groove with respect to the main body. It is designed to do.

The inventor of the present application also proposes a temporary building including a seat and a seat mounting bracket according to the present invention as one aspect of the present invention. The effect of such a temporary building is that rainwater is less likely to enter inside it.
An example temporary building is a long rectangle, and at least one sheet having a wall thickness portion thicker than the other parts at both ends in the width direction and the sheet are temporarily installed. It is a long length used for attaching to the building in a double state of the outside and the inside, and when it is used, a plurality of pieces are arranged in parallel so as to have an interval substantially corresponding to the width of the sheet. It is a temporary building equipped with at least two seat mounting brackets used in the above.
Two seat mounting brackets are provided on both sides of the long main body and the width direction of the main body over the entire length in the length direction of the main body along the length direction of the main body. The width of the opening is made larger than the thickness of the sheet and smaller than the thickness of the thick portion, and is provided with a locking groove in which the thick portion can be inserted. There is. Further, in the seat mounting bracket, one of the two locking grooves provided on one side in the width direction of the main body is an outer locking groove for mounting the outer seat, and the other is an outer locking groove. It is an inner locking groove located inside the outer locking groove when used for mounting the inner sheet, and the outer locking groove is located outside the inner locking groove with respect to the main body. It is designed to do.
In the temporary building, the seat mounting brackets are arranged so as to be inclined so that the longitudinal direction thereof is along the maximum inclination line in the portion of the temporary building, and the seat mounting brackets adjacent to each other are arranged. The wall thickness portion of the outer sheet is locked by the facing outer locking grooves, and the wall thickness of the inner sheet is locked by the facing inner locking grooves of the adjacent seat mounting brackets. Each part is locked.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

In this embodiment, a case of constructing a temporary building as shown in FIG. 1 will be described.
A temporary building is simply like a huge tent. Although not limited to this, the temporary building in this embodiment is used for dismantling an existing building such as a building or a cleaning factory, and covers the entire existing building completely. It is supposed to be. The temporary building is not limited to this, but in this embodiment, it is a rectangular shape in a plan view, and when it is large, its long side may reach 100 m, and its height may reach 50 m.

The temporary building according to this embodiment includes a plurality of bone members 10 as shown in FIGS. 1 and 2. FIG. 2 is a diagram showing only the bone member 10. The bone member 10 may have basically the same structure as those in a conventional temporary building.
Each bone member 10 is not limited to this, but in this embodiment, the bone members 10 are erected at equal intervals and so as to be parallel when viewed in a plan view.

Although not limited to this, each bone member 10 in this embodiment is the same. The bone member 10 serves as an aggregate for a temporary building and has the necessary rigidity. The bone member 10 is composed of, but not limited to, a metal square pipe in this embodiment.
The bone member 10 is configured to include two rod-shaped pillar portions 11 and two rod-shaped beam portions 12, both of which are rod-shaped. The pillar portion 11 becomes a pillar of the temporary building and forms a part of the wall, and the beam portion 12 becomes a beam of the temporary building and forms a part of the roof. The column portion 11 and the beam portion 12 may be integrated as a whole, but the two column portions 11 and the two beam portions 12 in this embodiment are separate members, and they are combined. By being fixed in the state described later, it becomes an integral bone member 10. Of course, at least one of the column portion 11 and the beam portion 12 may be further composed of a plurality of members.
The pillars 11 are erected substantially perpendicular to the ground at predetermined intervals. The lower end of the pillar portion 11 is fixed to the ground, and the method of fixing the pillar portion 11 may follow a well-known or known technique.
One ends of the two beam portions 12 are fixed to the upper ends of the two pillar portions 11, respectively. Further, the other ends of the two beam portions 12 are connected to each other. The two beam portions 12 are arranged to be in a straight line when viewed in a plan view. The other ends of the beam portions 12 connected to each other are higher in height than one end of the beam portions 12. Due to the structure of the beam portion 12, the roof of the temporary building is not limited to this, but is a so-called gable type.

Next, the sheet material constituting the temporary building will be described.
The structure of the sheet 20 may be the same as that of the conventional one, and specifically, the sheet 20 is configured as shown in FIG. As will be described later, the sheet 20 is stretched between adjacent bone members 10.
The sheet 20 includes a sheet material 21. The sheet material 21 may be, for example, a resin sheet or a sheet in which at least one surface of a woven fabric or knitted fabric made of fibers is coated with resin. Examples of the resin constituting the sheet material 21 are vinyl chloride resin, polyethylene and the like, and the thickness thereof is, for example, 0.5 mm to 2.0 mm. The sheet 20 can be wound or folded, but in this embodiment both of them are possible, and the sheet 20 has at least flexibility enough to be bent along the bone member 10.
The sheet 20 is a long rectangle as shown in FIG. 3 (A). The width of the sheet 20 is set to be the same as or slightly longer than the distance between adjacent bone members 10. The length of the sheet 20 in the longitudinal direction corresponds to the length of the bone member 10, that is, the total length of the two pillar portions 11 and the two beam portions 12. Of course, the sheet 20 may be a plurality of sheet materials bonded together by heat fusion or the like.
Thick portions 22 are provided at both ends of the sheet 20 in the width direction. The thickness of the wall thickness portion 22 is made larger than the thickness of the sheet material 21 constituting the sheet 20.
The wall thickness portion 22 is formed by, for example, folding back both ends of the sheet 20 as shown in FIG. 3 (B) and fixing the tip thereof from slightly inside the sheet 20 by welding, adhesion, sewing, or the like. Inside the tubular space over the entire length of the sheet 20 at both ends in the width direction of the sheet 20, a rope 23 flexible enough to be bent along the bone member 10 is arranged. Will be done. Alternatively, as shown in FIG. 3C, the thick portion 22 is a long and rectangular sheet on both the front and back surfaces of both ends of the sheet 20 and the center thereof is bent along the length direction. For example, it is a sheet configured in the same manner as the sheet material 21 except for its shape.) A sheet made by fixing the inner surfaces of both ends of an additional sheet piece 24 by welding, bonding, sewing, or the like. It is configured by arranging a flexible rope 23 inside a tubular space over the entire length of the sheet 20 at both ends in the width direction of the 20.
In any case, the thick portion 22 of the sheet 20 is thicker than the thickness of the sheet material 21. The thickness of the thick portion 22 is set so that it can be inserted into the outer locking groove and the inner locking groove, which will be described later, and does not come out from the openings of the outer locking groove and the inner locking groove. It should be noted that the thickness of the portion of the sheet 20 other than the thick portion 22 naturally includes the outer locking groove and the inner locking including the portion that is doubled or tripled to form the thick portion 22. It is thinner than the width of the groove opening.
The seat 20 is attached to the bone member 10 by using the seat attachment metal fittings.

Next, the seat mounting bracket used for mounting the seat 20 to the bone member 10 will be described.
The seat mounting bracket described below is used to fix the seat 20 to the beam portion 12 of the bone member 10, but in this embodiment, the same applies to the fixing of the seat 20 to the pillar portion 11. Seat mounting brackets are used.

A front view of the seat mounting bracket 100 is shown in FIG.
The seat mounting bracket 100 has a shape as shown in FIG. 4 and is long, and the vertical cross-sectional shape in FIG. 4 is the same in all parts in the length direction. Although not limited to this, the seat mounting bracket 100 is made of metal and is manufactured by, for example, extrusion molding.
The seat mounting bracket 100 has an outer locking member 111 having a substantially C-shaped cross section and an inner locking groove 112A inside the outer locking groove 111A on both sides in the width direction, respectively. It is provided with a C-shaped inner locking member 112.
The two outer locking members 111 are connected to each other by an outer connecting plate 113 which is a plate-like body, and the two inner locking members 112 are connected to each other by an inner connecting plate 114 which is a plate-shaped body. There is. Although not limited to this, the outer connection plate 113 and the inner connection plate 114 correspond to the main body of the seat mounting bracket referred to in the present application.
Further, the outer locking member 111 and the inner locking member 112 on the same side in the width direction of the seat mounting bracket 100 are a part thereof, and more specifically, below the inside in FIG. 4 of the former and outside of the latter. Above, they are integrated with each other.
The outer locking groove 111A described above is for locking the thick portion 22 of the outer sheet 20 described later. The thick portion 22 of the sheet 20 can be inserted into the outer locking groove 111A. Further, the portion of the sheet 20 other than the thick portion 22 can pass through the opening of the outer locking groove 111A. The above-mentioned inner locking groove 112A is for locking the thick portion 22 of the inner sheet 20 described later. The thick portion 22 of the sheet 20 can be inserted into the inner locking groove 112A. Further, the portion of the sheet 20 other than the thick portion 22 can pass through the opening of the inner locking groove 112A.
The outer locking groove 111A to the outer locking member 111 are located outside the inner locking groove 112A to the inner locking member 112.
A guide protrusion 115, which is a protrusion, is provided below the outer side of the outer locking member 111, or in other words, below the opening of the outer locking groove 111A. The guide protrusion 115 guides the dripping rainwater as described later.
A fixed leg 116 is provided below the inner locking member 112. The fixing leg 116 is used to fix the seat mounting bracket 100 to the bone member 10. The fixed leg 116 is bent outward below it, and has a locking claw 116A protruding upward at its tip. The function of the locking claw 116A will be described later.

The seat mounting bracket 100 as described above is mounted on the bone member 10 as shown in FIG.
The method of attaching the seat mounting bracket 100 to the beam portion 12 of the bone member 10 is as follows. The seat mounting bracket 100 is fixed to the beam portion 12 so that its length direction is along the length direction of the beam portion 12. When the seat mounting bracket 100 is mounted on the beam portion 12, the fixing bracket 200 is used.
The fixing metal fitting 200 is a metal fitting having a front shape as shown in FIG. 5 and is a set of two metal fittings. The fixing metal fitting 200 has a length of, for example, several times the diameter of a bolt, which will be described later, in the depth direction in FIG. That is, the fixing metal fitting 200 is not long. The fixing metal fitting 200 is used along the outer circumference of either the left or right half of the beam portion 12, and is formed by bending above the outer circumference of the beam portion 12 first inward and downward in FIG. It is equipped with 211. Further, the fixing metal fitting 200 is provided with a fixing portion 212 extending downward in FIG. 5 below the fixing metal fitting 200. The fixing portion 212 is provided with a hole (not shown).
The above-mentioned locking portions 211 of the two fixing metal fittings 200 can be locked from the outer upper side with respect to the locking claws 116A of the two fixing legs 116 of the seat mounting metal fitting 100, respectively. In that state, by screwing the nut 230 into the bolt 220 that penetrates the above-mentioned holes drilled in the fixing portions 212 of the two fixing metal fittings 200, the seat can be attached via the fixing metal fittings 200. The metal fitting 100 is fixed to the beam portion 12. Each seat mounting bracket 100 is fixed to the beam portion 12 by using the fixing bracket 200 at a plurality of appropriate positions in the length direction thereof.
As a result, the seat mounting bracket 100 is fixed to the beam portion 12 so as to cover the entire length of the beam portion 12. As is usually the case, if the seat mounting bracket 100 is shorter than the length of the beam portion 12, a plurality of seat mounting brackets 100 connected in the length direction are fixed to one beam portion 12. Will be done.
When the seat mounting bracket 100 is mounted on the beam portion 12, the cross sections of the outer connecting plate 113 and the inner connecting plate 114 of the seat mounting bracket 100 are both horizontal. Since the seat mounting bracket 100 is mounted on each beam portion 12, the seat mounting brackets 100 mounted on the beam portions 12 of the adjacent bone members 10 are externally locked on the side close to the seat mounting bracket 100 on the opposite side to each other. The grooves 111A and the inner locking grooves 112A face each other. The outer locking groove 111A is located outside the inner locking groove 112A when the temporary building is used as a reference.
Similarly, the seat mounting bracket 100 is attached to the pillar portion 11 of the bone member 10 so as to cover the entire length of the pillar portion 11. When the seat mounting bracket 100 is mounted on the pillar portion 11, both the outer connecting plate 113 and the inner connecting plate 114 of the seat mounting bracket 100 are made to coincide with the longitudinal direction in FIG. 1 of the temporary building. .. Since the seat mounting bracket 100 is mounted on each pillar portion 11, the seat mounting bracket 100 mounted on the pillar portion 11 in the adjacent bone member 10 is externally locked on the side close to the seat mounting bracket 100 on the opposite side to each other. The grooves 111A and the inner locking grooves 112A face each other. The outer locking groove 111A is located outside the inner locking groove 112A when the temporary building is used as a reference. Further, at the connecting portion between the pillar portion 11 and the beam portion 12, the ends of the seat mounting brackets 100 fixed to the pillar portion 11 and the beam portion 12 are almost in contact with each other at the same angle as the angle formed by the pillar portion 11 and the beam portion 12. It will be in the state of. At this time, the outer locking grooves 111A and the inner locking grooves 112A of both seat mounting brackets 100 are in a continuous state, but between the outer locking grooves 111A or between the inner locking grooves 112A. If a gap is generated, it is possible to fill the gap by arranging an appropriate member.

The seat 20 is attached to the seat attachment fitting 100 attached to the bone member 10 in this way.
The sheet 20 is stretched between adjacent bone members 10. The outer locking groove 111A and the inner locking groove 112A in the seat mounting bracket 100 attached to the one bone member 10 are formed on the one bone member 10 in the seat mounting bracket 100 attached to the adjacent bone member 10. It is in a state of facing the outer locking groove 111 and the inner locking groove 112A on the side close to the mounted seat mounting bracket 100, respectively. The two outer locking grooves 111A are paired with the outer locking grooves 111A, and the two outer locking grooves 111A are provided with thick portions 22 at both ends in the width direction of one sheet 20 in FIG. It is inserted from the lower end of the pillar portion 11 located on the front side of the above, or from the lower end of the pillar portion 11 located on the back side. Then, the tip of the seat 20 is guided to the outer locking grooves 111A of the seat mounting metal fittings 100 attached to the two pillars 11, and the thick portions 22 at both ends in the width direction are guided to the pillars 11. Pull up to the top of. Next, the outer locking groove 111A of the seat mounting bracket 100 attached to the two beam portions 12 and the outer locking groove 111A of the seat mounting bracket 100 attached to the opposite pillar portion 11 are filled with the meat. While guiding the thick portion 22, the tip of the sheet 20 is moved to the lower end of the pillar portion 11 on the opposite side.
As a result, the sheet 20 is placed between the two adjacent bone members 10 in a state where the thick portions 22 at both ends thereof are locked by the pair of outer locking grooves 111A between the two adjacent bone members 10. It will be in a stretched state.
Such work is performed in all of the two adjacent bone members 10.
Further, the same operation is performed between the pair of inner locking grooves 112A between the two adjacent bone members 10. As a result, the sheet 20 is placed between the two adjacent bone members 10 in a state where the thick portions 22 at both ends thereof are locked by the pair of inner locking grooves 112A between the two adjacent bone members 10. It will be in a stretched state. Of course, this work is performed in all of the pair of inner locking grooves 112A between the two adjacent bone members 10.
FIG. 6 shows a state in which the sheet 20 is stretched.

As a result, the sheet 20 is stretched over the two rectangular side surfaces of the four sides of the temporary building in FIG. 1 and the two rectangular roof surfaces.
On the other hand, the sides of the two pentagons in FIG. 1 are still open. Sheets are appropriately stretched on the sides of the two pentagons using a well-known or known method. A door 40 that can be opened and closed is provided on the side surface as needed, and the temporary building is completed.

Suppose there was rainfall after the temporary building was completed. Consider that rainwater adheres to the inclined sheet 20 of the portion constituting the beam portion 12.
In this case, rainwater adheres to the outer surface of the outer sheet 20. As shown by the arrow W in FIG. 7, a part of the rainwater travels along the outer surface of the outer sheet 20 and enters the outer locking groove 111A, and wraps around the thick portion 22 of the outer sheet 20. , It may reach the inner surface side of the outer sheet 20 and leak from the outer locking groove 111A again. At this time, the rainwater is located on the inner surface side of the outer sheet 20. As shown by the arrow W, the rainwater further drips along the portion below the opening of the outer locking groove 111A in the outer locking member 111. The rainwater discharged from the outer locking groove 111A drips directly onto the inner sheet 20, or when it reaches at least the guide projection 115, becomes water droplets W1 and drips onto the inner sheet 20.
In any case, the position of the inner sheet 20 on the outer surface on which the rainwater drips is a position away from the inner locking groove 112A, in other words, a position closer to the center in the width direction of the inner sheet 20. Since the rainwater that has fallen at such a position flows along the maximum inclination line of the inner seat 20, that is, along the length direction of the seat mounting bracket 100, it approaches the direction of the inner locking groove 112A. It does not enter the inner locking groove 112A. As a result, rainwater does not enter the inside of the inner sheet 20 through the inner locking groove 112A, that is, the inside of the temporary building.
The above effect does not occur in the part corresponding to the seat 20 that constitutes the side surface of the temporary building, but at least the mounting structure that is composed of the seat mounting bracket 100 or more is applied to the temporary building of rainwater. It does not promote invasion.

In this embodiment, the seat mounting bracket 100 is fixed to the bone member 10 along the bone member 10, but the positional relationship between the seat mounting bracket 100 and the seat 20 is different. As long as the positional relationship described in the above embodiment can be maintained, the positional relationship between the seat mounting bracket 100 and the bone member 10 is not limited as in the above embodiment. For example, it is possible to newly provide a bone member connecting the bone members 10 arranged in parallel in FIG. 1 and fix the seat mounting bracket 100 to the bone member 10.
Further, in the above-described embodiment, the seat mounting bracket 100 exists over the entire length of the bone member 10, but the seat mounting bracket 100 is located at least on the beam portion 12 or on a portion having the same inclination as the beam portion 12. It is enough if it exists. If the seat mounting bracket 100 is arranged along the entire length of the beam portion 12, the length of the seat 20 in that case is the total length of the two beam portions 12 included in one bone member 10. It is said to be the length of the beam.
