Description

  The present invention relates to a roof in a membrane structure formed by covering a roof portion or a wall surface portion of a dustproof temporary tent or the like with a membrane material to prevent dust generated during dismantling work or excavation work from scattering. Part waterproof structure.

  Conventionally, membrane structures, especially membrane structures that are not installed in one place for a long period of time, such as a temporary membrane structure, but are moved and installed in other places as needed, are cost-effective. In order to reduce the size, a configuration in which the size can be changed according to the installation purpose and the size of the installation location is preferable. Therefore, a membrane structure is used in which a plurality of ridges having the same or substantially the same shape are arranged in parallel, and the overall size (length) can be changed by increasing or decreasing the ridges.

  The ridge of the membrane structure is connected between the pair of ridge end frame members by connecting to a pair of ridge end frame members laid in the width direction of the membrane structure using connecting means such as eyelets. A membrane material (sheet) is stretched and configured, and a membrane structure is configured by arranging a plurality of the ridges in the length direction. At this time, a gap is formed between the adjacent ridges (between the roofs), and a gap is also formed at the connection between the ridge end frame material and the membrane material. A waterproof structure is adopted so as not to enter the membrane structure.

  As such a waterproof structure, as shown in FIG. 8 (a), a connecting film member 131 is stretched between the opposite ridge end frame members 107a and 107a of the adjacent ridges so as to block the ridges 130 of the adjacent ridges. The connecting portion waterproofing membrane covers the entire connecting portion where the sheet S ″ constituting the roof portion of the ridge and the connecting membrane material 131 are connected so as to sandwich the ridge end frame materials 107a and 107a from both sides. Covering the materials B and B, both ends of the waterproof membranes B and B of the connection portion are formed on the sheet S ″ and the connecting membrane material 131 that respectively constitute the roof portion of the ridge along the width direction of the membrane structure. A waterproof structure to be joined is used.

  Further, as shown in FIG. 8B, the inter-building waterproofing membrane material B longer than the interval between the ridges 103 without stretching the connecting membrane material 131 for closing the ridges between the adjacent ridges as described above. Is covered from one roof portion (sheet S ″) of the adjacent ridge to the other roof portion (sheet S ″) so as to cover the space from above, and both end portions of the inter-ridge waterproof film material B ′ are covered. A waterproof structure is also used in which the sheet S ″ constituting one roof portion and the sheet S ″ constituting the other roof portion are joined along the width direction of the membrane structure.

  However, the connecting portion waterproofing membrane material B, B or the inter-building waterproofing membrane material B ′ has different members (sheet S ″ and connecting membrane material 131, or one sheet S ″ of the adjacent ridge and the other at both ends). Therefore, the joining work must be performed after the connecting film member 131 or the sheet S ″ is stretched between the buildings 103 or between the buildings. In this case, since at least one of the membrane structures must be joined from the outdoor side (external side), the worker can work on the soft roof portion (sheet S ″) stretched between the frame members. Although it is indispensable, it is difficult to perform the work because the operator's feet sink, and it requires a lot of labor and complicated work. It was happening.

  Then, in view of the said problem, this invention makes it a subject to provide the roof part waterproofing structure of the membrane structure which can be constructed easily and easily from the indoor side (inside side).

  Therefore, in order to solve the above-mentioned problem, the waterproof structure of the roof portion of the membrane structure according to the present invention is configured by stretching a membrane material between a pair of building end frame members laid in the width direction, A roof structure waterproofing structure between adjacent ridges in a membrane structure in which a plurality of the ridges are juxtaposed in the longitudinal direction and an inter-ridge connecting membrane material is attached so as to block between adjacent ridges The membrane material covers the connection portion from above from the inside of the connection portion to between the ridges when the membrane material is stretched, and the connection portion provided with a connection means with the ridge end frame material. And a covering portion in which a pull-down member that is formed of a wire material and can be pulled down downward is provided at the front end portion along the width direction. The inter-building connecting membrane material is opposed to the inter-building portion in the length direction. Characterized in that it is formed longer than the interval of Totan unit rack 構材.

  According to such a configuration, the membrane material is stretched by connecting the connecting portion of the membrane material between the ridge end frame materials constituting the ridge, and the ridge connection membrane material is provided between the ridge end frame materials in the ridge portion. Is attached, the covering portion of the membrane material covers the connection portion from above from the inside to the ridge between the connection portions, and the tip of the covering portion is positioned above the inter-ridge connection membrane material between the ridges. Will be.

  Then, by pulling down the pull-down member provided at the distal end portion of the covering portion, the corresponding portion of the inter-building connecting membrane material located below the lower end portion is also lowered. At this time, since the inter-building connecting membrane material is attached between the opposing ridge end frame materials in the ridge portion, both ends are positioned at the height of the ridge end frame material, and the center side is the membrane material. Since it will be located in the height pulled down by the pulling-down member of a coating | coated part, it becomes groove shape. Therefore, when it rains, the groove-shaped inter-building connecting membrane material plays a role of so-called dredging, and drains rainwater on the roof portion of the membrane structure, in particular, the roof portion of the inter-building portion. In particular, it is possible to prevent the rainwater or the like from staying on the roof portion between the buildings.

  In addition, the portion where the membrane material and the inter-building connection membrane material are connected to the building edge frame material constituting the inter-building portion from both sides by connecting means, etc., is covered with the membrane material constituting the roof portion of the ridge. Since the portion is covered from above, the connected portion is not exposed to rainwater or the like. Therefore, the intrusion of rainwater from the roof portion in the membrane structure, particularly the roof portion between the ridges, can be firmly prevented.

  Further, in the lowering operation of the lowering member in the covering portion, the length of the inter-building connecting film material is longer than the interval between the opposite ridge end frame members in the inter-building portion, and therefore the lowering member in the covering portion is easy to lower. .

  Further, the connecting portion is formed as a separate member from the membrane material, and even if it is necessary to join the membrane material, only one end portion needs to be joined to the membrane material. It is not necessary to join after installation, and it is not necessary to perform work on the stretched membrane material. That is, since the work can be performed in a place where the joining work can be easily performed before the tensioning, the joining work is easy to perform. Further, even when the covering portion is joined to the film material instead of the connection portion, the joining operation is easily performed as described above.

  In addition, in this invention, the inner side in a film | membrane material means the center side of a ridge rather than the ridge edge part at the time of tensioning. In addition, the length refers to the distance in the length direction along the side-by-side direction of the ridges constituting the membrane structure, and the width refers to the width direction (along the ridge end frame material) perpendicular to the length direction. Direction). Inter-building refers to the gap between adjacent ridges, and the inter-building section refers to the opposite ends of the adjacent ridges and ridges in addition to the ridges (connection of building edge frame materials and membrane materials) Part and covering part).

  In addition, the inter-building connection membrane material is configured such that an inter-building central portion lowering member capable of lowering both ends downward is further provided in the central portion of the inter-building connection membrane material along the width direction. Is preferred.

  According to this configuration, similarly to the above, when the inter-building connecting membrane material is formed in a groove shape, the inter-building central portion lowering member provided in the inter-building connecting membrane material is located in the bottom central portion of the groove shape. Become. And by pulling down the inter-ridge central part lowering member at the central part of the groove-shaped bottom part, the groove-shaped bottom part has a V-shaped cross section, and rainwater flowing through the groove shape is collected at the bent part at the lower end, It becomes easier to drain along the groove shape.

  Further, a membrane material is stretched between a pair of building edge frame members constructed in the width direction to form a ridge, and a plurality of the ridges are juxtaposed in the length direction. The roof portion waterproofing structure between the ridges of the matching ridges, wherein the membrane material in one of the adjacent ridges is provided with a connection portion provided with a connection means with one ridge end frame material, and when the membrane material is stretched A pull-down member that extends from the inside to the ridge from the inside of the connection portion so as to cover the connection portion from above, is composed of a wire rod, and can be lowered downward at both ends thereof has a width at the tip portion. A covering portion provided along the direction, and a film-side end portion between the adjacent ridges, the membrane material in the other of the adjacent ridges, a connection portion provided with a connection means with the other ridge-end frame material, and a membrane When laying the material, from the inside to the one building The intercompartment side end is provided with an intercompartment covering part that extends so as to be able to cover the connection part from above, and is provided with a connecting means to the one ridge end part building material at the front end part thereof. The space covering portion may be configured to be longer than the interval between the one ridge end frame member and the other ridge end frame member facing each other in the length direction.

  According to this configuration, the membrane material is stretched by connecting the connecting portions of the membrane material between the ridge end frame materials constituting the ridge, and the one ridge end frame material in the inter-ridge portion of the adjacent ridges. When the other membrane material is connected by the connecting means at the tip of the inter-building covering portion, the inter-building covering portion of the other membrane material is connected to the other building material from the inner side to the other building material frame. The connecting portion of the film material and the space between the ridges are covered from above, and the covering portion of one film material extends from the inside to the space between the ridges so that the connection portion can be covered from above. The tip is located above the inter-building covering portion of the other film material that covers the inter-building.

  Then, by pulling down the pull-down member provided at the distal end portion of the covering portion of one film material, the corresponding portion of the covering portion between the ridges of the other film material located below the leading end portion is also lowered. At this time, the ridge covering part of the other membrane material is in a state where the tip is connected to one ridge end frame material and the inside is on the other ridge edge frame material, The inter-building covering portion at the position of the opposing ridge end frame material in the ridge portion is positioned at the height of the opposing ridge end frame material, and the center side is formed by the pulling-down member of the covering portion of the one film material Since it is located at the lowered height, it has a groove shape (a groove shape with a V-shaped cross section in which the position of the lowering member becomes a bent portion). Therefore, at the time of raining, the inter-ridge covering portion of the other groove-like membrane material can play a role of so-called roofs, and in particular, rainwater can be drained from the roof portion of the inter-ridge portion. It is possible to prevent rainwater or the like from collecting on the roof, particularly in the roof between the buildings.

  In addition, the part where one film material and the other inter-building covering part are connected to the one building edge part frame material constituting the inter-building part from the both sides by connecting means etc. is the roof part of one ridge The portion of the other ridge that is covered by the covering portion of the membrane material that is connected to the other ridge end frame by the connecting means is the ridge of the membrane material that constitutes the roof portion of the other ridge Since it is covered from above by the intermediate covering portion, the connected portion of the one and the other ridge is not exposed to rainwater or the like. Therefore, the intrusion of rainwater from the roof portion in the membrane structure, particularly the roof portion between the ridges, can be firmly prevented.

  Further, in the pulling down operation of the pulling member in the covering portion of the one film material, the length of the covering portion between the ridges of the other film material is longer than the interval between the ridge end frame materials facing the ridge portion, The pulling-down member in the coating portion of the one film material is easy to pull down.

  Further, the connecting portions of the one and the other film materials are formed as separate members from the film material, respectively, and even when one of the end portions is to be bonded to the film material, only one end is bonded to the film material. For this reason, it is not necessary to perform the joining after the membrane material is stretched, and the work on the stretched membrane material may not be performed. That is, since the work can be performed in a place where the joining work can be easily performed before the tensioning, the joining work is easy to perform. Therefore, when installing the membrane structure, it can be constructed simply and easily. In addition, instead of the connection part of the one and the other film material, the covering part of one film material and the covering part of the other film material are covered with one film material and the covering part of the other film material. Even in the case of bonding to a film material, it is easy to perform the bonding work.

  As mentioned above, according to this invention, the roof part waterproofing structure of the membrane structure which can be constructed easily and easily from the indoor side (inside side) can be provided.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

  In the present embodiment, as a membrane structure, a structure in which an arch-shaped frame material composed of steel, lightweight steel, or the like is combined, and a sheet (membrane material) that covers the structure and becomes a roof or a wall (membrane material) Dust-proof temporary tent that is configured to prevent scattering of dust generated by dismantling or excavation of structures to the outside, and can be resized according to the size of the structure to be dismantled and the site to be temporarily installed Will be simply referred to as a “tent”).

  As shown in FIG. 1, a dust-proof temporary tent (membrane structure) 1 includes a plurality of buildings 2, 2,... Arranged adjacent to each other with a predetermined interval (between buildings) 3 between the buildings 2 and 2. An entrance 4 is formed at the center of one end portion in the length direction. The tent 1 is configured such that the length (size) of the tent 1 can be changed by increasing or decreasing the number of the plurality of ridges 2, 2,. In this embodiment, the length direction refers to the direction in which the ridges 2, 2,... Are arranged side by side, and the width direction refers to a direction orthogonal to the length direction (frame member 5 (frame member 7 described later). ) Direction). The length refers to the distance in the length direction, and the width refers to the distance in the width direction.

  2, the ridge 2 is stretched so as to cover the film material (sheet) S over the plurality of arch-shaped frame members 5, 5,... It is composed of that. The frame member 5 is constructed by laying a frame member (beam member) 7 that is curved upward between a pair of upright vertical members 6 and 6. The vertical structural member 6 or the frame member 7 is formed of a so-called truss member in which two parallel rod-shaped steel members are connected in a sawtooth shape.

  Of the plurality of standing frame members 5, 5,..., A pair of frame members 5, 5 standing on both ends of the ridge 2 are particularly referred to as ridge end frame members 5a, 5a. The frame material of the ridge end frame material 5a is referred to as a ridge end frame material 7a.

  As shown in FIGS. 3 to 5, the sheet S is a substantially rectangular film material. For example, at least one surface of a woven or knitted fabric of inorganic fiber, synthetic fiber, and natural fiber is coated with synthetic resin or rubber. Sheet, synthetic resin sheet, rubber sheet, and the like can be used, but in this embodiment, a polyester resin woven fabric coated on both surfaces of a synthetic fiber is used. . Further, the sheet S includes a connection portion 10 and a covering portion 11 at an end portion on the side of the building 3 in the length direction. The connecting portion 10 is provided at the end in the length direction of the sheet S. In detail, the connection part 10 is provided with eyelets 12, 12,... At equal intervals along the front end side edge as connection means for connecting to the ridge end frame member 5a. Then, the wire S such as a rope or a wire is inserted into the eyelets 12, 12,... Of the connecting portion 10, the wire r is wound around the ridge end frame material 5a, and the tension is applied to the sheet S. Is stretched.

  The covering portion 11 is joined to the upper surface inside the connection portion 10 of the sheet S, and when the sheet S is connected to the ridge end frame member 5a by the connection portion 10 as described above (at the time of stretching), It extends so as to cover the connecting part 10 from above from the inside to the inter-building 3 from the connecting part 10. The covering portion 11 can be joined to the sheet S by sewing, bonding with an adhesive, welding by heat, or the like, but in this embodiment, it is performed by welding by heat. Specifically, the covering portion 11 is formed so as to protrude further toward the front end side than the end portion of the sheet S, and a lowering member 13 is provided at the front end portion. In the present embodiment, the leading end of the sheet S is folded back into a cylindrical shape, and the wire 13 is inserted into the cylinder as the pulling member 13. As the wire 13, a rope, rubber, wire, or the like can be used. In the present embodiment, a rope (so-called edge rope) is used.

  In the present embodiment, the inner side of the sheet S refers to the center side of the ridge 2 rather than the ridge end when the frame members 5, 5,. The inter-building 3 refers to the gap between the adjacent ridge 2 and the ridge 2, and the inter-building section 30 refers to the opposite end of the adjacent ridge 2 and the ridge 2 in addition to the inter-building 3 (building The end frame member 5a, the connecting portion 10 of the sheet S, the covering portion 11 and the like.

  The inter-compartment connecting film material 31 is located in the gap between the ridge 2 and the ridge 2 so that rainwater from the outside does not enter the inside through the gap and internal dust does not scatter outside. It is attached so as to close the gap. At this time, the inter-building connection film material 31 is attached so as to be positioned below the pull-down member 13 at the front end portion of the covering portion 11 in the sheet S stretched on the ridge end frame member 5a. The inter-compartment connection film material 31 is a wide band-like sheet body made of the same material as the sheet S, and the length in the length direction of the tent 1 is opposed to the inter-compartment portion 30 of the adjacent ridges 2 and 2. It is a sheet body longer than the interval between the ridge end frame members 5a and 5a. Like the connecting portion 10 of the sheet S, eyelets (not shown) as connecting means are provided at equal intervals at both ends in the longitudinal direction of the connecting film member 31 between the buildings. It is connected and fixed by winding wire rods r such as ropes, which are inserted through the eyelets, around the opposite ridge end frame members 5a and 5a. In addition, the inter-building connection membrane material 31 is provided with an inter-building central portion lowering member 32 made of a wire along the width direction at the center in the length direction. A rope, rubber, a wire, or the like can be adopted as the inter-building central portion lowering member 32, but in the present embodiment, it is composed of the wire 32.

  The intercompartment 3 configured as described above is configured such that the sheet S is stretched by connecting the connection part 10 of the sheet S between the ridge end frame members 5a and 5a constituting the ridge 2 and When the inter-building connecting membrane material 31 is attached between the end frame members 5a and 5a, the covering portion 11 of the sheet S covers the connecting portion 10 from above from the inside to the inter-building 3 from the connecting portion 10. The tip of the covering portion 11 is located above the inter-building connection film material 31 of the inter-building 3.

  And in the roof part of the inter-building part 30, the site | part corresponding to the inter-building connection film | membrane material 31 located in the downward direction with this front-end | tip part by pulling down the both ends of the lowering member 13 provided in the front-end | tip part of the coating | coated part 11 Is also reduced. At this time, the inter-building connection membrane material 31 is attached between the opposing ridge end frame members 7a and 7a (part corresponding to the roof portion of the ridge end frame members 5a and 5a) of the inter-building portion 30. Both ends are positioned at the height of the ridge end frame members 7a, 7a, and the central portion side of the inter-building portion 30 is positioned at the height lowered by the pulling member 13 of the covering portion 11 in the sheet S. Groove shape.

  In addition, in this embodiment, the sheet | seat S and the connecting film material 31 between buildings are the sheet | seat S and the connecting film material between buildings which the both wall parts and roof part which comprise the tent 1 were each substantially processed into one sheet. 31 is comprised. Therefore, the wall portion of the inter-building portion 30 is also configured in the same manner as described above. By pulling the both ends of the lowering portion 13 on the ground side downward and pulling them into the inner side of the tent 1 along the ground, the inter-building portion 30 is formed. In the same manner as described above, the inter-building connecting membrane material 31 has a groove shape not only in the roof portion but also in the wall portion.

  Further, at the center of the groove-shaped bottom portion, that is, at the center of the inter-building connecting film material 31, an inter-building central portion lowering member 32 is provided along the width direction, and both ends of the inter-ridge central portion lowering member 32 are provided. Down (or pulling in while lowering both ends on the ground side), the groove-shaped bottom central portion becomes substantially V-shaped in the cross section along the length direction, and the groove as a whole is in the same direction. Is formed into a substantially pentagonal shape in which the cross section is upside down (see FIG. 5).

  As described above, at least in the roof portion, the inter-building portion 30 is configured as described above, so that the roof portion of the tent 1 has a structure that prevents intrusion of rainwater and the like from such a portion in the inter-building portion 30 ( Waterproof structure).

  That is, at the time of raining, the groove-shaped inter-building connecting membrane material 31 plays a role of so-called dredging, and can effectively drain rain water on the roof portion of the tent 1, in particular, the roof portion of the inter-building portion 30. It is possible to prevent rainwater or the like from collecting on the roof portion of the inter-building portion 30 in the tent 1.

  In addition, the part where the sheet S and the inter-building connecting film material 31 are connected to the ridge end frame members 7a and 7a constituting the inter-building portion 30 from both sides by connecting means (eyelet etc.) Since the covering portion 11 of the sheet S constituting the roof portion is covered from above, the connected portion is not exposed to rainwater or the like. Accordingly, it is possible to firmly prevent rainwater from entering from the roof portion of the tent 1, particularly from the roof portion of the inter-building portion 30.

  Further, in the operation of lowering the pull-down member 13 in the covering portion 11 of the inter-building portion 30 (or the pulling-in), the length of the inter-building connecting film material 31 is the length of the ridge end frame members 7a, 7a facing each other. Since the length of the inter-building connecting membrane material 31 is approximately the same as the interval between the ridge end frame members 7a, 7a, the pull-down member 13 in the covering portion can be easily pulled down (or pulled in) because it is longer than the interval. The inter-building connection film material 31 is easily formed in a groove shape.

  Further, the covering portion 11 is formed as a separate member from the sheet S, and must be joined to the sheet S. However, the covering portion 11 straddles the ridge end frame member 5a (the ridge end portion frame material 7a) and covers the both end sides respectively. Since it is not necessary to join S and the inter-building connection membrane material 31 and only one end portion needs to be joined to the sheet S, it is not necessary to join the sheet S and the inter-building connection membrane material 31 after stretching. Therefore, the work on the stretched sheet S or the inter-building connecting membrane material 31 does not have to be performed. That is, since the work can be performed at a place where the joining work can be easily performed before the tensioning, the joining work is extremely easy to perform. Therefore, when installing the tent 1, it can construct simply and easily. Moreover, even if it is the structure which joins not the coating | coated part 11 but the connection part 10 to the sheet | seat S like this embodiment, it is easy to perform a joining operation similarly to the above. In this case as well, the connecting portion 10 may be joined to the sheet S by sewing, bonding with an adhesive, welding by heat, or the like.

  Further, the inter-building connection film material 31 is configured such that the both ends of the inter-building central portion lowering member 32 are pulled down (or pulled in while pulling down both ends on the ground side), so that the groove-shaped bottom central portion is in the length direction. The cross section along the line is substantially V-shaped, and the entire groove is formed with a substantially pentagonal groove whose cross section in the same direction is turned upside down. Collected and easier to drain along the groove

  In addition, the roof part waterproof structure of the tent (membrane structure) 1 of the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention. .

  For example, in the present embodiment, the inter-building connection membrane material 31 is provided with the inter-building central portion lowering member 32, and by lowering both ends of the inter-building central portion lowering member 32 downward, Although a substantially pentagonal groove having an inverted cross-section is formed, it is not necessary to be limited to this, and as shown in FIG. Also good. In this case, the cross section along the length direction has a substantially trapezoidal shape in the reverse direction, but even in such a cross-sectional shape, the roof portion in the tent 1, particularly the roof in the intercompartment portion 30, plays the role of a fence. It is possible to drain the rainwater of the portion, and it is possible to prevent the rainwater from collecting on the roof portion of the tent 1, particularly the roof portion of the inter-building portion 30.

  Further, as shown in FIG. 7, the sheet S in one of the adjacent ridges is connected to the connection portion 10 provided with connection means (eyelet or the like) with one ridge end frame member 7 a (ridge end frame member 5 a). When the sheet S is stretched, it extends so as to cover the connecting portion 10 from the upper side to the inter-building 3 from the inside of the connecting portion 10, and is composed of a wire and pulls both ends downward. And a covering member 11 provided at the front end along the width direction. The sheet S ′ on the other side of the adjacent ridge is provided on the other ridge end frame. 7'a (building edge part frame material 5'a) connecting portion 10 'provided with a connecting means (eyelet or the like), and the one ridge from the inside of the connecting portion 10' when the sheet S 'is stretched Can cover the connecting part 10 'from above The inter-building covering portion 11 ′ is provided at the end of the inter-building 3 side, and the inter-building covering portion 11 ′ is provided with a connecting means for connecting to the one ridge end frame member 7a at the front end portion thereof. In the length direction, it may be configured to be longer than the interval between the one ridge end frame member 7a and the other ridge end frame member 7'a facing each other in the inter-ridge portion 30.

  Even in this configuration, when the inter-building covering portion 11 ′ of the other sheet S ′ is connected to one ridge end frame member 7 a in the inter-ridge portion 30 ′ of the adjacent ridge by the connecting means at the tip, The inter-building covering portion 11 ′ of the other sheet S ′ is connected to the connecting portion 10 ′ of the other sheet S and the inter-building 3 from the inner side of the connecting portion 10 ′ of the other sheet S ′ to the one ridge end frame member 7a. Is covered from above, and the tip of the covering portion 11 of one sheet S is positioned above the covering portion 11 ′ of the other sheet S ′ covering the space 3.

  And by pulling down the pull-down member 13 provided at the leading end of the covering portion 11 of one sheet S, the corresponding portion of the inter-building covering portion 11 ′ of the other sheet S ′ located below the leading end portion. Is also reduced. At this time, the inter-building covering portion 11 ′ of the other sheet S ′ is connected to the one ridge end frame member 7 a at the tip, and the inner side rides above the other ridge end frame material 7 ′ a. Since it is in a state, the inter-building covering portion 11 'at the position of the opposing ridge end frame members 7a, 7'a in the ridge portion 30' is the same as the opposite ridge end frame materials 7a, 7'a. Since it is located at a height and the center side is located at a height lowered by the lowering member 13 of the covering portion 11 of the one sheet S, a groove shape (a position corresponding to the lowering member 13 is a bent portion). And a cross-sectional V-shaped groove). Therefore, when it rains, the inter-building covering portion 11 ′ of the other groove-shaped sheet S ′ serves as a soot, and can drain the rainwater from the roof portion, particularly the roof portion of the inter-building portion 30 ′. It is possible to prevent rainwater or the like from accumulating on the roof portion of 1, particularly the roof portion of the inter-building portion 30 ′.

  In addition, the portion where one sheet S and the other inter-building covering portion 11 ′ are connected to the one ridge-end frame member 7 a constituting the inter-building portion 30 ′ from both sides by connecting means or the like, A connecting portion 10 ′ that is covered from above by the covering portion 11 of the sheet S constituting the roof portion of the ridge, and the other sheet S ′ is connected to the other ridge end frame member 7′a by connecting means, Since it is covered from above by the inter-building covering portion 11 'of the sheet S' constituting the roof portion of the other ridge, the connected portions of the one and the other ridge are exposed to rainwater or the like, respectively. There is no. Accordingly, it is possible to firmly prevent rainwater from entering from the roof portion of the tent 1, particularly from the roof portion of the inter-building portion 30 ′.

  Further, in the lowering operation of the lowering member 13 in the covering portion 11 of the one sheet S, the length of the inter-building covering portion 11 ′ of the other sheet S ′ is the ridge end frame member 7 a facing the inter-building portion 30 ′. , 7'a, the pull-down member 13 in the covering portion 11 of the one sheet S is easily pulled down as described above.

  Further, the connecting portions 10 and 10 ′ of the one sheet S and the other sheet S ′ are formed as separate members from the sheets S and S ′, and must be joined to the sheets S and S ′. However, as described above, since only one end portion needs to be joined to the sheets S and S ′, there is no need to join after the sheets S and S ′ are stretched, and on the stretched sheets S and S ′. Since the work does not have to be performed, the joining work can be performed before tensioning. Therefore, when installing the tent 1, it can construct simply and easily. In addition, not in each connection part 10 and 10 ', even when joining the covering part 11 of the one sheet S and the ridge covering part 11' of the other sheet S 'to the sheets S and S', Similarly, it is easy to perform joining work.

  Moreover, in this embodiment, since the roof part and the wall part are integrally comprised by the sheet | seat S in the width direction, the said tent 1 is comprised also in the wall part of the inter-building part 30. However, it is not necessary to be limited to this, and it is sufficient that the waterproof structure is configured at least in the roof portion of the inter-building portion 30.

  Moreover, in this embodiment, although the roof part of the tent 1 is comprised by the curved surface curved toward the upper direction, it is not necessary to be limited to this and may be a direction or a gable. In this case, the lowering member at the front end of the covering portion of the sheet is not a rope but a wire having rigidity corresponding to the shape of the roof portion. By doing in this way, when the lowering member is pulled downward, only the covering portion of the sheet at the corner portion (for example, the upper side end portion of the flow) formed in the roof portion is not lowered, and the roof portion The covering portion of the sheet in the entire width direction is pulled down, and a waterproof structure similar to the above can be configured.
