Description

The present invention mainly relates to a mounting bracket for attaching a seat, and a seat structure configured using the mounting bracket and the seat.

For example, when demolishing a building, the building is demolished using heavy equipment such as a power shovel at the demolition site, divided into pieces, and the resulting waste is separated and disposed of using an appropriate method.
When such demolition work is performed near residential areas, hospitals, schools, etc., dust is likely to be scattered. Buildings that are subject to demolition are usually old buildings, which may generate dust containing substances that are harmful to health such as asbestos, and waste disposal sites, including incinerators, may be subject to demolition. In such cases, dust containing substances such as dioxins, which are also harmful to health, may be generated. The scattering of dust is likely to be seen as a major problem by nearby residents, especially when it generates dust that is undesirable for health.
Demolition of buildings also creates noise, which can cause problems with neighboring residents.

When performing some kind of work, such as building demolition work, a temporary tent is used to prevent the dust and noise generated by the work from escaping outside the building. A technique is used to cover the entire object.
Such a temporary tent is constructed of, for example, aggregates such as columns and beams, and a sheet that covers at least part of the aggregates or the gaps between the aggregates. The sheet may be double-layered to further emphasize the purpose of preventing dust and noise from escaping to the outside.

In order to fix the seat to a temporary tent, a mounting bracket for fixing the seat is used, and a seat structure composed of the mounting bracket and the sheet is known.
The sheet to be attached to such a seat mounting bracket is generally a long rectangle, and has a thick part formed by making the thickness of the part thicker than the other parts over the entire length of both ends in the width direction. We are prepared. In many cases, the thick part is a bendable rod-shaped body of a certain thickness (e.g. rope).
The mounting brackets are long, and in most cases, they are connected along the length of the seat so as to correspond to the length of the seat, and are separated at intervals corresponding to the length of the seat in the width direction. They are used by arranging a set of two in parallel. The mounting brackets are also provided with long locking grooves for locking the ends of the sheet in the width direction, and when the two mounting brackets are arranged in parallel, the locking grooves in the two mounting brackets The openings are arranged to face each other.
The locking groove is a groove into which the thick portion of the sheet can be inserted, and the width of the opening of the locking groove is narrower than the width on the back side. 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 part of the sheet is inserted into the wide part on the back side of the locking groove. Then, even if a force is applied to the edge of the sheet toward the center in the width direction of the sheet, the thick part that interferes with the edge of the groove opening will be locked to the groove opening and will not come out of the locking groove. The thick part will not fall out of the locking groove.

Patent No. 3927567

By the way, the above-mentioned sheet structure also has some points to be improved.
When a strong wind blows around a tent, etc. that has a sheet structure, the force that the sheet receives from the strong wind can destroy not only the sheet structure but also the tent, etc. that has the sheet structure, including the aggregate. The point is that there is a risk of
The mounting brackets that make up the seat structure are generally attached to the aggregate of the tent, but if the seat is subjected to a large force from strong winds, the force will be transferred to the aggregate of the tent through the mounting brackets. As a result, the entire tent, including the aggregates, may be destroyed by strong winds.
Temporary tents used for building demolition can exceed 50 meters in height, and the area of the sheet that is exposed to strong winds is extremely large, so an extremely large force is applied to the sheet. As a result, there is a high possibility that the entire tent will be destroyed, and when such a situation occurs, the damage is likely to be large.
Of course, given the high accuracy of current weather forecasting, it is possible to predict in advance when strong winds will blow due to the approach of a typhoon, for example. It is also possible to take measures such as removing the sheet from the seat or leaving at least a portion of the sheet loose.
However, it is difficult to adopt a structure that makes this possible for temporary structures such as tents that are adopted with the aim of reducing costs, and temporary tents that adopt such a structure Even so, if the above measures are taken by humans, and if humans decide whether or not to take the above measures, then the above measures can always be taken when necessary. Since this is not always the case, there is still a possibility that the tent will be destroyed. In addition, if the above-mentioned responses or judgments are to be automatically performed by a machine, the necessary costs will be incurred and the costs will increase.
Incidentally, such a problem is not limited to temporary tents, but is common to the above-mentioned seat structures or mounting fittings included in the above-mentioned seat structures in general.

An object of the present invention is to provide an inexpensive sheet structure or related technology that can avoid damage to the tent even when strong winds blow.

In order to solve the above problems, the inventor of the present application proposes the following invention.
The present invention is a long rectangular sheet used for attaching a sheet having thick portions having the same configuration on both edges in the width direction, each having a thickness thicker than other portions. This is a mounting bracket for mounting a seat, which is used by arranging two pieces in parallel with each other at an interval that substantially corresponds to the width of the seat.
The mounting bracket is provided along the length of the elongated material and the entire length of the elongated material, and the width of the opening is equal to the width of the opening of the elongated material. and smaller than the thickness of the thick part, and are parallel to each other and facing each other when the mounting bracket is used, and the thick part can be inserted therein. and a locking groove.
The configurations of the mounting bracket and the seat described above are the same as those described in the background art section, and may follow the conventional configurations.
A first locking groove, which is one of the locking grooves, and a second locking groove, which is the other of the locking grooves, in the two mounting brackets used as a set are arranged in a predetermined manner on the elongated material. When the force acts, the thick portion located in the first locking groove deforms and falls off from the first locking groove, but the thick portion located in the second locking groove Even if the thick portion is deformed, it will not fall off from the second locking groove.
Therefore, if such mounting brackets are used, the seat attached to such mounting brackets should be properly designed with the above-mentioned "predetermined force", so that the tent will not break unless the mounting brackets are devised. When a wind of a certain strength blows, or a wind of a certain strength blows, the thick part that was locked in the first locking groove falls off from the first locking groove, and the second It becomes possible to create a situation in which the thick portion that was locked in the locking groove remains in the second locking groove as it is. In this state, of the two thick parts of the sheet, the edge on the side of the thick part that fell off from the first locking groove becomes a free end, so if the wind blows at a certain strength or more, Even so, the "predetermined force" or more force is no longer applied to the sheet. Therefore, by using the mounting hardware of the present invention, it is possible to prevent the entire tent including the aggregate from breaking due to the large force generated by strong winds acting on the sheet. In addition, in the mounting bracket of the present invention, even if one thick part of the sheet falls off from the first locking groove, the other thick part remains in the second locking groove, so the seat itself will not fall somewhere. You can prevent it from flying away.
Moreover, as mentioned above, the thick part comes off from the first locking groove only when a wind of a certain strength blows, and it is necessary to rely on human hands to remove the thick part from the first locking groove. Nor does it require human judgment. Therefore, if the mounting bracket of the present invention is used, the thick part will automatically come off from the first locking groove when it should be removed from the first locking groove, so the entire tent will not be destroyed. In addition, the cost for removing the thick portion from the first locking groove can be suppressed.

As described above, the first locking groove, which is one of the locking grooves, and the second locking groove, which is the other locking groove, in the two mounting brackets used as a set are located at a predetermined position in the main body of the seat. When the force is applied, the thick part located in the first locking groove is deformed and falls off from the first locking groove, but the thick part located in the second locking groove is not deformed. In order to cause the thick portion to selectively fall off from the first locking groove and the second locking groove, for example, The width of the opening of the first locking groove may be wider than the width of the opening of the second locking groove.

The inventor of this application also proposes the following sheet structure as one aspect of the invention of this application. The following effects of the seat structure are equivalent to those of the mounting hardware described above.
An example of a sheet structure is a long rectangular sheet structure, and a sheet having thick portions having the same structure and thicker than other portions on both edges in the width direction, and the sheet is attached to the sheet structure. and two mounting brackets for mounting the seat, which are long and used for mounting the seat, and are arranged in parallel with each other at an interval that substantially corresponds to the width of the seat when the seat is in use. This is a sheet structure.
The mounting bracket is provided along the length of the elongated material and the entire length of the elongated material, and the width of the opening thereof is the same as that of the sheet. and smaller than the thickness of the thick part, and are parallel to each other and facing each other when the mounting bracket is used, and the thick part can be inserted therein. and a locking groove.
A first locking groove, which is one of the locking grooves, and a second locking groove, which is the other of the locking grooves, in the two mounting brackets used as a set are arranged in a predetermined manner on the elongated material. When the force acts, the thick portion located in the first locking groove deforms and falls off from the first locking groove, but the thick portion located in the second locking groove Even if the thick portion is deformed, it will not fall off from the second locking groove.
The inventor of this application also proposes the following tent as one aspect of the invention of this application. The following effects of the tent are equivalent to those of the mounting hardware described above.
An example tent is a tent that includes a sheet structure according to the present invention. Examples of how to use the tent according to the present invention include those described in the background section.

FIG. 2 is a diagram for explaining the movement of rainwater when it rains while a sheet is attached to the sheet mounting bracket included in the temporary building shown in FIG. 1. FIG.

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

In this embodiment, a case will be explained in which the mounting fittings or sheet structure of the present invention are applied to a temporary building as shown in FIG.
Although not limited to this, the temporary structure in this embodiment is simply a huge tent. Although not limited to this, the temporary structure in this embodiment is used to demolish an existing structure such as a building or an incineration plant, and is designed to completely cover the entire existing structure. considered as something. Although not limited to this, the temporary building has a rectangular shape in plan view in this embodiment, and if it is large, its long sides 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 frame members 10 may have basically the same structure as those in conventional temporary buildings.
Although not limited thereto, in this embodiment, each bone member 10 is erected at regular intervals and parallel to each other when viewed from above.

Although not limited to this, each bone member 10 in this embodiment is the same. The frame member 10 serves as an aggregate for a temporary building, and has the necessary rigidity. Although not limited to this, the bone member 10 is constructed of a square metal pipe in this embodiment.
The bone member 10 includes two column parts 11, both of which are rod-shaped, and two beam parts 12, both of which are rod-shaped. The column portions 11 serve as pillars of the temporary building and constitute a part of the wall, and the beam portions 12 serve as beams of the temporary building and constitute a part of the roof. Although the column portion 11 and the beam portion 12 may be integrated as a whole, the two column portions 11 and the two beam portions 12 in this embodiment are separate members, and when they are combined, By being fixed in the state described below, it becomes an integral bone member 10. Of course, at least one of the column part 11 and the beam part 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 may be based on well-known or publicly known techniques. The lower end of the column portion 11 may be directly fixed to the ground, or may be indirectly fixed to the ground via another member.
One ends of the two beam sections 12 are fixed to the upper ends of the two column sections 11, respectively. Further, the other ends of the two beam portions 12 are connected to each other. The two beam portions 12 are arranged in a straight line when viewed from above. The other ends of the beam portions 12 that are connected to each other are higher in height than one end of the beam portions 12. Due to the configuration of the beam portion 12, the roof of the temporary building has a so-called gable shape, although it is not limited to this.

Next, the sheets constituting the temporary building will be explained.
The structure of the sheet 20 may be the same as that of a conventional sheet except for a thick portion which will be described later, and specifically, the structure is as shown in FIG. 3. Sheet 20 is stretched between adjacent bone members 10 as described below.
The sheet 20 includes a sheet material 21. The sheet material 21 can be, for example, a sheet made of resin, or a sheet in which at least one side of a woven or knitted fabric made of fibers is coated with resin. Examples of the resin constituting the sheet material 21 are vinyl chloride resin, polyethylene resin, and the like. The thickness of the sheet material 21 is, for example, 0.5 mm to 2.0 mm. The sheet 20 is capable of being rolled up or folded, and in this embodiment both are possible, and has flexibility to the extent that it can be bent at least along the rib members 10. Note that the sheet 20 may have a large number of holes, for example, depending on its use, or may have a knitted shape depending on the case.
The sheet 20 is a long rectangle as shown in FIG. 3(A). The width of the sheet 20 is equal to 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 sum of the lengths of the two column parts 11 and the two beam parts 12. Of course, the sheet 20 may be a plurality of sheet materials 21 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 thick portion 22 is greater than the thickness of the sheet material 21 constituting the sheet 20.
For example, the thick portion 22 is formed by folding both ends of the sheet 20 as shown in FIG. A rod-shaped body 23 that is flexible enough to be bent along the bone member 10 is disposed inside the cylindrical space that is created by this process and spans the entire length of the sheet 20 in the longitudinal direction of the sheet 20 at both ends of the sheet 20 in the width direction. It consists of Alternatively, as shown in FIG. 3(C), the thick portion 22 may be formed by forming a long rectangular sheet (with a long rectangular shape and a bend along the length direction) on both the front and back sides of both ends of the sheet 20. For example, a sheet made by fixing the inner surfaces of both ends of the additional sheet piece 24 (which is a sheet having the same structure as the sheet material 21 except for the shape) by welding, gluing, sewing, etc. It is constructed by disposing a flexible rod-shaped body 23 inside a cylindrical space extending over the entire length of the sheet 20 in the longitudinal direction at both ends of the sheet 20 in the width direction. The rod-shaped body 23 can be made of rubber, for example, and the structure including the material thereof will be described later.
In any case, the thick portion 22 of the sheet 20 is thicker than the sheet material 21. The thickness of the thick part 22 is such that it can be inserted into the outer locking groove and the inner locking groove described later, and when no force is applied to the sheet material 21, the outer locking groove and the inner locking groove can be inserted. The thickness is such that it will not slip out of the opening. Note that the thickness of the portion of the sheet 20 other than the thick portion 22 is, of course, the thickness of the outer locking groove and the inner locking portion, including the double or triple layered portion to constitute the thick portion 22. It is smaller than the width of the groove opening.
In addition, when providing the thick part 22 on the sheet 20 using the rod-shaped body 23, the method of fixing the rod-shaped body 23 to the sheet 20 is not limited to the above-mentioned method, and may be achieved by, for example, suturing or adhesive. .
Further, the two thick portions 22 provided on one sheet 20 have the same configuration. Here, "same" includes a symmetrical relationship.
The sheet 20 is attached to the bone member 10 using sheet attachment fittings, which will be described later.

Next, the sheet attachment fittings used to attach the sheet 20 to the bone member 10 will be explained.
Note that the sheet attachment fittings described below are used to fix the sheet 20 to the beam portion 12 of the frame member 10, but in this embodiment, a similar sheet is also used to fix the sheet 20 to the column portion 11. Mounting hardware is used.

A front view of the seat mounting bracket 100 is shown in FIG. Although not limited thereto, in this embodiment, all the seat mounting brackets 100 have the same configuration as shown in FIG. 4.
The seat mounting bracket 100 has a shape as shown in FIG. 4 and is elongated, and its vertical cross-sectional shape in FIG. 4 is the same throughout its length. Although not limited thereto, the seat mounting bracket 100 is made of metal, and is manufactured, for example, by extrusion molding.
The seat mounting bracket 100 has an outer locking member 111 having a substantially C-shaped cross section, which has an outer locking groove 111A on the inside thereof, and an outer locking member 111 having a substantially C-shaped cross section, which has an inner locking groove 112A inside thereof, on both sides of the seat mounting bracket 100 in the width direction. It is provided with a letter-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-shaped 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 locking member 111 and the inner locking member 112 on the same side in the width direction of the seat mounting bracket 100 are part of the same, and more specifically, the former in FIG. They are integrated into each other below the inner side and above the outer side of the latter.
The above-mentioned outer locking groove 111A is for locking the thick portion 22 of the outer sheet 20, which will be described later. The thick portion 22 of the seat 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. However, the width of one opening (the right side in FIG. 4) of the two outer locking grooves 111A provided in one mounting bracket 100 is wider than the width of the other opening (the left side in FIG. 4). .
The above-mentioned inner locking groove 112A is for locking the thick portion 22 of the inner sheet 20, which will be described later. The thick portion 22 of the seat 20 can be inserted into the inner locking groove 112A. Further, the portion of the seat 20 other than the thick portion 22 is configured to be able to pass through the opening of the inner locking groove 112A. However, the width of one opening (the right side in FIG. 4) of the two inner locking grooves 112A provided in one mounting bracket 100 is wider than the width of the other opening (the left side in FIG. 4). .
The outer locking groove 111A on the right side in FIG. 4 and the inner locking groove 112A on the right side in FIG. 4 correspond to the first locking groove in the present application, and the width of the opening is relatively narrow. The left outer locking groove 111A and the inner locking groove 112A correspond to the second locking groove in the present application.
Although not limited thereto, 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 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 dripping rainwater as will be described later. However, the guide protrusion 115 is not essential to the present invention.
A fixed leg 116 is provided below the inner locking member 112. The fixing legs 116 are used to fix the seat mounting bracket 100 to the bone member 10. The fixed leg 116 is bent outward at its lower part, and has a locking claw 116A projecting upward at its tip. The function of the locking claw 116A will be described later.

The seat attachment fitting 100 as described above is attached to the bone member 10 as shown in FIG.
The method of attaching the sheet attachment fitting 100 to the beam portion 12 of the frame member 10 is as follows. The seat mounting bracket 100 is fixed to the beam portion 12 with its length direction along the length direction of the beam portion 12. When attaching the seat attachment fitting 100 to the beam portion 12, a fixing fitting 200 is used. Note that the beam portion 12 in FIG. 5 is one of the members constituting the beam portion 12, and may be a long member extending along the beam portion 12.
The fixing fittings 200 are a set of two fittings having a front shape as shown in FIG. The fixing fitting 200 has a length in the depth direction in FIG. 5 that is, for example, several times the diameter of a bolt to be described later. In other words, the fixing fitting 200 is not long. The fixing fitting 200 is used along the outer periphery of either the left or right half of the beam portion 12, and has a locking portion formed above it by first bending inward and then downward in FIG. It is equipped with 211. Further, the fixing fitting 200 is provided with a fixing portion 212 extending downward in FIG. 5 below. The fixing portion 212 is provided with a hole (not shown).
The above-mentioned locking portions 211 of the two fixing fittings 200 can each be locked to the locking claws 116A of the two fixing legs 116 of the seat mounting fitting 100 from outside and above. In this state, by threading the nuts 230 onto the bolts 220 that pass through the holes drilled in the fixing parts 212 of the two fixing fittings 200, the seat mounting fittings can be attached via the fixing fittings 200. 100 is adapted to be fixed to the beam portion 12. Each seat attachment fitting 100 is fixed to the beam portion 12 using fixing fittings 200 at a plurality of appropriate positions along its length.
As a result, the seat mounting bracket 100 is fixed to the beam portion 12 over the entire length of the beam portion 12. Note that if the seat mounting brackets 100 are shorter than the length of the beam portion 12, which is usually the case, a plurality of seat mounting brackets 100 connected in the length direction of the beam portion 12 are fixed to one beam portion 12. It turns out.
When the seat mounting bracket 100 is attached to the beam portion 12, the outer connecting plate 113 and the inner connecting plate 114 of the seat mounting bracket 100 are both arranged so that their cross sections are horizontal. Since the seat mounting brackets 100 are attached to each beam portion 12, the outer locking grooves 111A of the seat mounting brackets 100 attached to the beam portions 12 of adjacent frame members 10 are connected to each other on the sides closer to the opposite sheet mounting brackets 100. , and the inner locking grooves 112A are opposed to 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 attachment fitting 100 is attached to the column 11 of the bone member 10 so as to span the entire length of the column 11. When the seat mounting bracket 100 is attached to the column part 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 of the temporary building in FIG. 1. Since the seat mounting brackets 100 are attached to each pillar 11, the outer locking grooves 111A of the seat mounting brackets 100 attached to the pillars 11 in adjacent frame members 10 are connected to each other on the sides closer to the opposite seat mounting brackets 100. , and the inner locking grooves 112A are opposed to each other. The outer locking groove 111A is located outside the inner locking groove 112A when the temporary building is used as a reference. In addition, at the connection portion between the column part 11 and the beam part 12, the ends of the seat mounting brackets 100 each fixed to the column part 11 and the beam part 12 are almost in contact with each other at the same angle as the angle formed by the column part 11 and the beam part 12. state. At this time, the outer locking grooves 111A and the inner locking grooves 112A in both seat mounting brackets 100 are in a continuous state, but there is a gap between the outer locking grooves 111A or between the inner locking grooves 112A. If this occurs, it is possible to fill the gap by arranging an appropriate member.

The seat 20 is attached to the seat attachment fitting 100 that has been attached to the bone member 10 in this manner.
The sheet 20 is stretched between adjacent bone members 10.
The outer locking groove 111A and the inner locking groove 112A of the seat mounting bracket 100 attached to one bone member 10 are the same as those of the seat mounting bracket 100 attached to the adjacent bone member 10. The outer locking groove 111 and the inner locking groove 112A on the side closer to the seat mounting bracket 100 are opposed to each other. The opposing outer locking grooves 111A are used as a pair of outer locking grooves 111A, and the thick portions 22 at both widthwise ends of one sheet 20 are attached to the two outer locking grooves 111A, respectively. Insert from the lower end of the column 11 located on the front side or from the lower end of the column 11 located on the rear side. Then, while guiding the thick portions 22 at both ends of the sheet 20 in the width direction to the opposing outer locking grooves 111A of the seat mounting bracket 100 attached to the two pillars 11, Pull it up to the top. Next, the thick portions are inserted into the outer locking groove 111A of the seat mounting bracket 100 attached to the two beam parts 12 and the outer locking groove 111A of the seat mounting bracket 100 attached to the column part 11 on the opposite side. 22, the tip of the sheet 20 is moved until it reaches the lower end of the pillar portion 11 on the opposite side.
Thereby, the sheet 20 is placed between the two adjacent bone members 10 with the thick portions 22 at both ends thereof being locked by the pair of outer locking grooves 111A between the two adjacent bone members 10. It will be in a stretched state.
This operation is performed everywhere between two adjacent bone members 10.
Further, the same operation is performed between a pair of inner locking grooves 112A between two adjacent bone members 10. Thereby, the sheet 20 is placed between the two adjacent bone members 10 with the thick portions 22 at both ends thereof being locked by the pair of inner locking grooves 112A between the two adjacent bone members 10. It will be in a stretched state. This operation is performed in all areas between the pair of inner locking grooves 112A between two adjacent bone members 10.
FIG. 6 shows a state in which the sheet 20 is stretched. For convenience of drawing, the width of the sheet 20 in FIG. 6 (the length in the left-right direction in FIG. 6) is drawn much smaller than the actual width.
The openings of the outer locking groove 111A and the inner locking groove 112A, which correspond to the first locking groove in the present invention of the seat mounting bracket 100, are the same as the openings of the first locking groove 111A and the second locking groove in the present invention of other seat mounting brackets 100. It faces the opening of the locking groove 112A. Therefore, one thick part of the sheet 20 is attached to the outer locking groove 111A or inner locking groove 112A, which has a relatively wide opening corresponding to the first locking groove in the present invention, and the other thick part of the sheet 20 The thick portion is attached to the outer locking groove 111A or the inner locking groove 112A, which corresponds to the second locking groove in the present invention and has a relatively narrow opening width.

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

Suppose that it rains after the temporary building is completed. Let us consider that rainwater adheres to the inclined sheet 20 that constitutes 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, some of this rainwater travels along the outer surface of the outer sheet 20, enters the outer locking groove 111A, and goes around the thick part 22 of the outer sheet 20. , and may reach the inner surface of the outer sheet 20 and leak again from the outer locking groove 111A. At this time, rainwater is located on the inner surface side of the outer sheet 20. This rainwater further drips down through the lower part of the opening of the outer locking groove 111A in the outer locking member 111, as shown by the arrow W. The rainwater coming out of the outer locking groove 111A either drips directly onto the inner sheet 20, or at least reaches the guide protrusion 115, where it becomes water droplets W1 and drips onto the inner sheet 20.
In any case, the position on the outer surface of the inner sheet 20 from which rainwater drips is away from the inner locking groove 112A, in other words, a position closer to the center of the inner sheet 20 in the width direction. Rainwater that falls at such a position flows in the direction along the maximum inclination line of the inner sheet 20, that is, along the length direction of the seat mounting bracket 100, so it approaches the inner locking groove 112A and flows inward. It does not enter the locking groove 112A. This prevents rainwater from entering further inside the inner sheet 20, that is, into the inside of the temporary building, through the inner locking groove 112A.
Although the above effect does not occur in the portion corresponding to the sheet 20 that constitutes the side surface of the temporary building, at least the mounting structure constituted by the sheet mounting bracket 100 prevents rainwater from entering the temporary building. will not be promoted.

Suppose a strong wind blows after a temporary building is completed. Even in that case, the building in this embodiment, which is a tent, is not damaged to the extent that at least its bone members 10 are damaged.
As shown in FIG. 6, each seat 20 has an outer locking groove 111A in the outer locking member 111, which is a set of two, or an inner locking groove 111A in the inner locking member 112, which is a set of two. The thick portions 22 on both edges in the width direction are locked by the locking grooves 112A, thereby being fixed to the building.

For now, attention will be paid to the sheet 20 whose thick portions 22 at both edges are locked to the outer locking groove 111A of the outer locking member 111 located above the center in the left-right direction in FIG.
This sheet 20 has thick portions 22 at the left edge and right edge in FIG. 6, respectively. The configurations of these thick portions 22 are the same.
The thick portion 22 on the left side of the seat 20 located above the center in the left-right direction in FIG. 6 is inserted into the outer locking groove 111A corresponding to the first locking groove in the present invention Since the width of the opening 111A is relatively wide, when a predetermined force is applied to the sheet 20, it deforms and falls off from the outer locking groove 111A. On the other hand, the thick portion 22 on the right side of the seat 20 located above the center in the left-right direction in FIG. 6 and inserted into the outer locking groove 111A corresponding to the second locking groove in the present invention Because the width of the opening of the locking groove 111A is relatively narrow, even if a predetermined force is applied to the sheet 20 to cause the thick portion 22 on the left side to fall off from the outer locking groove 111A, some deformation will occur. It does not fall off from the outer locking groove 111A.
The force that acts on the sheet 20 when wind at a certain speed blows against the sheet 20 can be easily determined by calculation. Therefore, by appropriately determining the above-mentioned "predetermined force", when wind at a certain speed blows around the building, which is a tent, the outer locking groove on the left side corresponding to the first locking groove in the present invention can be In order to prevent the thick portion 22 on the left side of the sheet 20 from falling off from the groove 111A, and the thick portion 22 on the right side of the sheet 20 from falling off from the outer locking groove 111A on the right side, which corresponds to the second locking groove in the present invention. can do.
The two outer locking grooves 111A in this embodiment are configured in this manner. If the thick part 22 of the sheet 20 does not fall off from the outer locking groove 111A even if a strong wind blows within the possible range, then the wind blows at a wind speed above a certain level and exerts a large force on the sheet 20. In such a case, the force may be transmitted from the seat attachment fitting 100 to the bone member 10, and the bone member 10 may be damaged as a result. If the above-mentioned "predetermined force" is appropriately determined in a range that the bone member 10 can withstand, depending on the strength of the bone member 10, a certain amount of force can be applied to the sheet 20 that the bone member 10 can withstand. When the wind blows, the left thick portion 22 inserted into the left outer locking groove 111A, which corresponds to the first locking groove in the present invention, falls off from the outer locking groove 111A, and the first locking groove in the present invention falls off. A situation arises in which the right thick portion 22 inserted into the right outer locking groove 111A corresponding to the second locking groove does not fall off from the outer locking groove 111A. In this case, even if the sheet 20, whose edge where the left thick portion 22 that fell off from the outer locking groove 111A is located is the free end, receives a stronger wind from then on, it will not receive a greater force from the wind. It disappears. Therefore, even if the building, which is a tent in this embodiment, is exposed to strong winds, it will not suffer major damage accompanied by damage to the bone members 10.
This also applies to the inner sheet 20.

In addition, as already explained using FIG. 3, the thick part 22 is equipped with the rod-shaped body 23. In FIG. 3, the rod-shaped body 23 has a circular cross section, but this is not limited to this. However, if the cross section is circular, the thick portion 22 will be able to fall off from the outer locking groove 111A corresponding to the first locking groove with good reproducibility when a "predetermined force" is applied to the sheet 20.
The rod-shaped body 23 may be made of a fiber rope, but may also be made of rubber. Although the deformation of the rod-shaped body 23 to the thick portion 22 is preferably elastic deformation, the deformation performed by the rod-shaped body 23 to the thick portion 22 may or may not be elastic deformation. If the deformation of the rod-shaped body 23 or the thick portion 22 is elastic deformation, it is advantageous to reuse the sheet 20 from which the thick portion 22 has fallen off from the outer locking groove 111A corresponding to the first locking groove.

In addition, in this embodiment, in all of the sheets 20 used for buildings, one of the thick portions 22 is supported by the outer locking groove 111A or the inner locking groove 112A, which corresponds to the first locking groove in the present invention. At the same time, the other thick portion 22 is supported by the outer locking groove 111A or the inner locking groove 112A, which corresponds to the second locking groove in the present invention.
Therefore, in the building that is a tent in this embodiment, when wind at a certain wind speed blows around the building that is a tent, all of the sheets 20 correspond to the first locking groove in the present invention. The thick part 22 inserted into the left outer locking groove 111A or the inner locking groove 112A in 6 falls off from the outer locking groove 111A or the inner locking groove 112A, and corresponds to the second locking groove in the present invention. A situation arises in which the thick portion 22 inserted into the outer locking groove 111A or the inner locking groove 112A on the right side in FIG. 6 does not fall off from the outer locking groove 111A or the inner locking groove 112A. Thereby, in this building, damage that would damage the bone member 10 does not occur.
The sheet 20 whose thick portion 22 has fallen off from the outer locking groove 111A or the inner locking groove 112A corresponding to the first locking groove can be fixed to the building again by the method described above.
In addition, in all the sheets 20 used for buildings, the thick portion 22 inserted into the left outer locking groove 111A or inner locking groove 112A in FIG. 6, which corresponds to the first locking groove in the present invention, is The wall thickness that falls off from the outer locking groove 111A or the inner locking groove 112A and is inserted into the outer locking groove 111A or the inner locking groove 112A on the right side in FIG. 6, which corresponds to the second locking groove in the present invention. There is no need to prevent the portion 22 from falling off from the outer locking groove 111A or the inner locking groove 112A. Such a phenomenon occurs only in some sheets 20, and in other sheets 20, a configuration may be adopted in which both thick portions 22 do not fall off from the outer locking groove 111A or the inner locking groove 112A.

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 the same as in the above embodiment. The positional relationship between the seat mounting bracket 100 and the bone member 10 is not limited to that in the above-described embodiment, as long as the positional relationship described above can be maintained. For example, it is possible to newly provide a bone member that connects the bone members 10 that are lined up in parallel in FIG.
Further, in the above-described embodiment, the seat attachment fittings 100 were present over the entire length of the frame member 10, but the seat attachment fittings 100 may be provided only on at least a portion of the column portion 11 and the beam portion 12.
Further, in the above-described embodiment, the sheet 20 has a double structure, but this is not limited to this, and for example, the sheet 20 may have a single layer structure. In that case, it is sufficient that only one of the outer locking member 111 and the inner locking member 112 of the seat mounting bracket 100 exists.
