Description

  The present invention relates to a tent sheet used for a tent that covers an upper side of a building under construction, a general tent that is stretched for rain or sunshade, and the like.

  It is well known that a tent is stretched on the upper part of the scaffolding for curing at a construction site, and a tent is stretched on a frame constructed with pipes for rain and awning. For example, when building a wooden house, a pillar material or the like is prevented from getting wet due to rain until a roof is constructed, and a tent covering a building under construction is stretched as an awning. Such a tent is fixed and stretched as appropriate to a scaffold or a building. When the tent receives wind, the wind pressure acts on the scaffold or the like, but when the wind is strong, the scaffold or building I tried to remove the tent because it could collapse.

  On the other hand, a tent sheet has been devised in which an opening is provided to allow wind to escape. For example, as shown in FIG. 7, a vent opening 91 is formed in the tent sheet 90, and a sheet-like lid 92 is provided so as to cover the opening 91 and only one side is sewn. As a result, when wind blows from the inside of the tent sheet 90, the lid 92 is blown by the wind pressure, and the wind passes through the opening 91. On the other hand, when it rains, rainwater flows on the lid 92 and the opening 91 Rainwater does not enter (see, for example, Patent Documents 1 and 2). Although not shown in the drawings, a tent sheet having an opening that is opened and closed by a fastener has also been devised (see, for example, Patent Document 3).

Japanese Patent Laid-Open No. 8-120943 JP-A-8-158705 Japanese Patent Laid-Open No. 9-277056

  The wind is strong in the upper part of the scaffold, and the wind blows in various directions due to the influence of the building under construction and the adjacent building. The lid 92 rises when the wind blows from the inside of the tent seat 90. The opening 91 is opened. However, when wind blows from the outside of the tent sheet 90, there is a problem that the opening 91 remains closed and the wind does not escape from the opening 91. Also, if the lid 92 is completely lifted, the lid 92 may not return even if the wind stops. Even if the lid 92 returns, the rain is falling because the opening 91 is open while the wind is blowing. There is also a problem of end.

  On the other hand, the configuration in which the opening is opened and closed with the fastener is troublesome because the fastener needs to be opened and closed depending on the rain or wind conditions. Further, when the tent sheet is used as a construction sheet, it is difficult to open and close the fasteners because the tent sheet is stretched so as to cover the upper side of the building under construction.

  The present invention has been made in view of these points, and is generally used as a tent that is stretched with a predetermined gradient on a scaffold or the like built on a site and covers the upper side of a building under construction, and is used as rain or an awning It is an object of the present invention to provide a means for allowing a tent to escape a wind to be blown or blown without entering rainwater in a tent.

  The present invention relates to a tent sheet stretched at a predetermined gradient, in which a flexible sheet band has a lower end portion of an upper sheet band on a gradient layer superimposed on an upper end portion of a lower sheet band. Arranged in parallel in the gradient direction, the sheet band between the predetermined fixing lines is loosened with respect to the adjacent upper and lower gradient sheet bands to form an air vent, and each sheet band has a predetermined interval It is fixed by a fixing line in a gradient direction, the distance between the fixing lines is 30 to 60 cm, and the dimension between the fixing lines of the loosened sheet band is approximately 4/3 times the distance between the fixing lines. And

  Further, the present invention is characterized in that the sheet band between the fixing lines is slackened with respect to the adjacent upper and lower sheet bands in a staggered manner on the inclined surface of the tent sheet.

  According to the tent sheet of the present invention, the flexible sheet band is arranged in parallel in the gradient direction with the lower end portion of the upper sheet band on the gradient overlaid on the upper end portion of the lower lower sheet band. Therefore, rainwater that flows according to the gradient does not enter from the inside of the sheet band to the inside, and the wind band is formed by slackening the sheet band between the predetermined fixing lines with respect to the adjacent upper and lower gradient sheet bands. Therefore, an air vent opening formed between the sheet belt and the lower sheet belt opens to the wind that blows up to release the wind, and to the wind that blows, A vent opening formed between the sheet belt and the sheet belt opens to allow the wind to escape. Thereby, it is possible to reduce the wind pressure acting on the tent sheet by escaping the wind with respect to both the blowing wind and the blowing wind, and rainwater does not enter even when the wind vent is opened.

  Moreover, since the distance between the adhering lines is narrowed to 30 to 60 cm, it is difficult for rainwater to accumulate on the loosened portion of the sheet band. In addition, since the dimension between the fixing lines of the slackened portion is about 4/3 times the distance between the fixing lines, it is possible to secure a sufficiently large air vent and improve the airflow. it can.

  In addition, on the slope surface of the tent sheet, a large number of winds are averaged over the entire surface of the tent sheet by loosening the sheet belt between the adhering lines with respect to the adjacent slope upper and lower sheet bands in a staggered manner. A hole can be formed, and the above-described effects can be maximized.

Hereinafter, the tent sheet according to the embodiment of the present invention will be described in detail.
The present tent sheet 1 can be used as a curing tent in a residential building, or as a general tent for rain and awning, but in the present embodiment, a case where it is used as a curing tent will be described as an example. To do. As shown in FIG. 1, the present tent sheet 1 is stretched over a scaffold 3 assembled on a site with a predetermined gradient to cover the upper side of a building under construction, thereby constructing a building such as a house. Prevents the pillars of the building under construction from getting wet in the rain or awning. Of course, the present tent sheet 1 can be used as a curing tent not only for residential construction but also for roof replacement, dismantling and the like. The scaffold 3 is made of steel pipes, wood, etc., and is assembled so as to surround the building to be constructed. However, the positional relationship of the scaffold 3 with the materials and the building is not particularly limited, and in any known and arbitrary scaffold This tent sheet 1 can be used. In addition, the tent sheet 1 is stretched at a sufficiently high position with respect to the building to be constructed so that it can be used when constructing the roof of the building. There is no particular limitation, and for example, the extension position may be appropriately changed according to the building situation of the building.

  As shown in FIG. 1, the tent sheet 1 has a plurality of flexible sheet bands 1A to 1J, 2 partially overlapped and arranged in parallel in a gradient direction, and the tent sheet 1 has a gable roof shape. Since it is to be stretched, the five sheet belts 1A to 1E and the five sheet belts 1F to 1J are formed so as to form the respective inclined surfaces, and the sheet belt 2 is provided in the central portion corresponding to the ridge. It has been. The central part corresponding to the ridge of the tent sheet 1 is placed on the wire 4 laid between the scaffolds 3 or suspended by a carabiner or the like, and the tent is shaped like a gable roof so that each slope surface hangs down from the wire 4. A sheet 1 is stretched, and a rope or the like is inserted through an eyelet appropriately provided at an edge corresponding to the eaves, and is fixed to the scaffold 3 or the building. Since the tent sheet 1 is slidable with respect to the wire 4 and each of the sheet bands 1A to 1J is flexible, the tent sheet 1 is slid so that the edge of the tent sheet 1 is removed from the scaffold 3 and folded to one side. By doing so, the upper part of the scaffold 3 covered with the tent sheet 1 can be opened. Note that such a method of stretching the tent sheet 1 is an example, and it is not always necessary to stretch the gable roof, and if it is stretched with a predetermined slope, it is shaped like a single-flow roof or a sliding roof. It may be stretched. Further, a ring member may be provided at the center of the tent sheet 1 and the wire 4 may be inserted through the ring member so as to be opened and closed.

  The sheet belts 1A to 1J, 2 are made of woven fabric, resin sheet or the like, and are preferably waterproof and lightweight. In the present embodiment, ten sheet strips 1A to 1J having a width of about 1.2 m are formed as one gradient surface by five sheets, but the width of the sheet belt and the number of parallel sheet belts per gradient surface are appropriately changed. Is possible. Since the sloped surface composed of the five sheet strips 1A to 1E and the sloped surface composed of the other five sheet strips 1F to 1J are the same, the tent sheet stretched in the shape of a gable roof The sheet belts 1A to 1E constituting the one-sided gradient surface will be described as an example.

  As shown in FIG. 2, each of the sheet bands 1A to 1E is arranged in parallel with the gradient direction, that is, with the longitudinal direction orthogonal to the gradient direction, from the upper side of the gradient to the lower side of the gradient, the sheet bands 1A, 1B, 1C, 1D and 1E are arranged in this order, and the lower end of the sheet band 1A on the upper side of the gradient is overlaid on the upper end of the sheet band 1B on the lower side of the gradient, and the lower end of the sheet band 1B is further on the lower side of the gradient. The sheet bands 1C, 1D, and 1E are similarly stacked on the upper end portion of the sheet band 1C. The overlap allowance of each of the sheet belts 1A to 1E is set so that rainwater that flows down according to the inclined surface does not enter the inside of the tent sheet 1 from the overlapped portion and the air vent is easily opened. About 40 cm is suitable for each of the sheet strips 1A to 1E having a width of about 1.2 m.

  As shown in FIG. 2, the sheet bands 1 </ b> A to 1 </ b> E, each end portion of which is overlapped and arranged in parallel in the gradient direction, are attached to the fixing line 10 in the gradient direction at a predetermined interval, for example, about 50 cm. The sheet bands 1A to 1E between the fixing lines, which are between the fixing lines 10 in the gradient direction, are loosened with respect to the adjacent sheet bands on the upper and lower gradient sides. It is stitched along each fixing line 10. Specifically, as shown in FIG. 3, the distance in the longitudinal direction between the fixing lines 12C sandwiched between the fixing lines 10 of the sheet band 1C is defined as the distance between the fixing lines 12B of the upper sheet band 1B and the lower side of the inclination. The slack portion Y is formed in the sheet band 1C with respect to the sheet bands 1B and 1D on the upper and lower sides of the gradient, which is greater than about 50 cm, which is the distance in the longitudinal direction between the fixing lines 12D of the sheet band 1D. By this slack portion Y, an opening is formed in the overlapping portion of the upper end portion of the sheet band 1C and the lower end portion of the sheet band 1B, and the overlapping portion of the lower end portion of the sheet band 1C and the upper end portion of the sheet band 1D. The openings are air vents 20BC and 20CD, respectively.

  In the sheet band 1C, a slack portion Y similar to that between the fixing lines 12C is provided intermittently between the fixing lines, that is, between the fixing lines 14C and 16C, as shown in FIG. Air vents are formed at the lower ends. The other sheet belts 1A, 1B, 1D, and 1E are provided with the same slack portion Y, but each slack portion Y is provided in a staggered manner on the slope surface formed by the sheet belts 1A to 1E. That is, in the sheet band 1A and the sheet band 1E, similarly to the sheet band 1C, the slack portions Y are provided between the fixing lines 12A, 14A, and 16A and between the fixing lines 12E, 14E, and 16E. In 1D, the slack portion Y is provided between the fixing lines 11B, 13B, 15B, and 17B, and the fixing lines 11D, 13D, 15D, and 17D, which are intermittent portions where the slack portion Y is not provided in the sheet bands 1A, 1C, and 1E. It has been. The size of the slack portion Y of each of the sheet belts 1A to 1E is set in consideration of the size of the opening used as the air vent, and is preferably about 1.2 to 1.5 times the distance between the fixing lines. is there.

  The distance between the fixing lines 10 and the size of the slack portion Y of each of the sheet bands 1A to 1E can be set to an arbitrary size. However, in this embodiment, in order to make it difficult for rainwater to collect between the fixing lines 10, FIG. As shown, with respect to the distance of about 50 cm between the fixing lines 10, the size of the slack portion Y of each of the sheet bands 1 </ b> B to 1 </ b> D is set to 66 cm, which is approximately 4/3 times that. More specifically, in each of the sheet bands 1B to 1D, the space between the fixing lines 10 where the slack portions Y are formed is higher on the sheet bands 1A to 1E than between the fixing lines 10 where the slack portions Y are not formed. Rainwater tends to accumulate, and in particular, if the distance between the fixing lines 10 and the size of the slack portion Y are increased, the amount of rainwater that accumulates between the fixing lines 10 where the slack portions Y are formed increases, as shown in FIG. The rainwater W remains accumulated without flowing down. Then, for example, as the amount of rainwater W accumulated on the sheet belt 1C increases, the sheet belt 1C that should originally be superimposed on the sheet belt 1D as shown in FIG. The slack portion Y formed on the sheet band 1B is drawn toward the sheet band 1B side, the sheet band 1C is further loosened, the distance between the fixing lines 10 is narrowed, and the slack section Y may enter under the sheet band 1D. . In this case, the rainwater W collected on the sheet band 1C enters the inside of the tent sheet 1 from the opening K formed between the slack portion Y of the sheet band 1C and the sheet band 1D. In order to prevent such a situation, the applicant changes the distance between the fixing lines 10 and the size of the slack portion Y as appropriate, and how the rainwater W easily collects and how the wind escapes change. I studied earnestly. Further, when the distance between the fixing lines 10 is reduced, the amount of rainwater W collected on each of the sheet belts 1A to 1E is small, and the sheet tent 1 is likely to flow down simply by shaking, etc. Taking into account the fact that the quality is determined by the total area of the air vent, the distance between the fixing lines 10 and the dimension of the slack portion Y are determined to be the above-mentioned size.

  In addition, the distance between the adhering lines 10 is not limited to this embodiment, and an effect of making it difficult to collect rainwater in the range of 30 cm to 60 cm can be obtained. In addition, by setting the size of the slack portion Y to be approximately 4/3 times the distance between the fixing lines 10, it is possible to secure a sufficiently large air vent and improve the airflow.

In this way, the sheet bands 1A to 1E are stitched along the fixing lines 10 by loosening between the fixing lines in a staggered manner, and are not shown in detail in the drawing, but are stretched like a gable roof. Similarly, the sheet bands 1F to 1J constituting the other slope surfaces of the tent sheet 1 are also stitched along the fixing lines 10 by loosening between the fixing lines in a zigzag pattern. As shown in FIG. 2, the sheet band 1A and the sheet band 1F on the side are overlapped with the upper ends of the sheet bands 1A and 1F and stitched along the fixing lines 10 to form one tent. A sheet 1 is configured. In the present embodiment, the sheet belts 1A to 1J, 2 are fixed together along the fixing line 10, but other fixing means such as bonding with an adhesive or heat fusion may be used. Good.

Hereinafter, how to blow up and blow off the wind and how to flow rainwater will be described by taking the air vents 20BC and 20CD between the fixing lines 12B, 12C and 12D as an example.
As shown in FIG. 3, by providing a slack between the fixing lines 12C of the sheet band 1C, the overlapping part of the upper end part of the sheet band 1C and the lower end part of the sheet band 1B, and the lower end part of the sheet band 1C Air vents 20BC and 20CD are formed in the overlapping portion with the upper end of the sheet band 1D, respectively. When the wind blows from the inside of the tent sheet 1, each of the sheet strips 1B, 1C, 1D receives the wind and tries to move upward. However, as shown in FIG. As a result, the upper end portion of the sheet band 1C between the fixing lines 12C is pressed against the lower end portion of the sheet band 1B between the fixing lines 12B. Therefore, the wind hardly passes through the air vent 20BC. On the other hand, the wind vent 20CD is in a state in which the lower end portion of the sheet band 1C between the fixing lines 12C swells upward due to wind pressure, and is opened by the amount of slackness relative to the upper end portion of the sheet band 1D between the fixing lines 12D. Therefore, the wind blown from the inside of the tent sheet 1 passes through the air vent 20CD and escapes to the outside of the tent sheet 1.

  On the contrary, when the wind blows from the outside of the tent sheet 1, each of the sheet bands 1B, 1C, 1D receives the wind and tries to go down, but as shown in FIG. In the opening 20BC, the upper end portion of the sheet band 1C between the fixing lines 12C is squeezed downward by the wind pressure, and the opening 20BC is opened by the amount of slackness relative to the lower end portion of the sheet band 1B between the fixing lines 12B. Therefore, the wind blown from the outside of the tent sheet 1 passes through the air vent 20BC and escapes to the inside of the tent sheet 1. On the other hand, the wind vent 20CD is hardly opened because the lower end of the sheet band 1C between the fixing lines 12C is pressed against the upper end of the sheet band 1D between the fixing lines 12D due to the wind pressure. Therefore, the wind hardly passes through the air vent 20CD. As described above, the wind vent 20CD opens to the wind blown from the inside of the tent sheet 1 to release the wind, and the wind vent 20BC opens to the wind blown from the outside to release the wind. The wind pressure acting on the tent sheet 1 can be reduced with respect to both the blowing wind and the blowing wind.

  Moreover, since each sheet belt | band | zone 1B, 1C, 1D has piled up the lower end part of the sheet | seat band of the gradient upper side on the upper edge part of the sheet | seat band of the gradient lower side, the rain water which flows according to a gradient is inside from between each sheet | seat band. There is no intrusion. Further, when the wind blows up from the inside of the tent sheet 1, as shown in FIG. 5, since the air vent 20BC is hardly opened, rainwater does not enter inside from the air vent 20BC. In addition, although the air vent 20CD is open, the lower end portion of the sheet band 1C is swollen upward in the 12C between the fixing lines, so that rainwater flows to both sides of the air vent 20CD and enters the inside from the air vent 20CD. There is no intrusion. Even if rainwater flows into the air vent 20CD, the rainwater is received by the sheet band 1D between the fixing lines 12D below the gradient and further flows down according to the gradient. On the other hand, when the wind is blowing from the outside of the tent sheet 1, as shown in FIG. 6, the wind vent 20BC is open, but the rain water flowing down from the wind vent 20BC is on the lower side of the gradient. Is received by the sheet band 1C between the fixing lines 12C and further flows down according to the gradient, so that rainwater does not enter inside from the air vent 20BC, and since the air vent CD is hardly opened, the rainwater Does not enter inside through the air vent 20CD. Thus, rainwater does not enter the inside of the tent sheet 1 even when the air vents 20BC and 20CD are opened by the blowing wind or the blowing wind.

  The other wind vents are the same, and will not be described in detail. However, on each inclined surface of the tent sheet 1, a plurality of slanted slacks are provided between the fixing lines on the entire surface of each inclined surface. Therefore, the wind can be escaped from the entire surface of the tent sheet 1 with respect to either the blowing wind or the blowing wind.

  In the present embodiment, the case where the tent sheet 1 is used as a curing tent in a residential building has been described as an example. However, naturally, the use of the tent sheet according to the present invention is not limited to the curing tent. It is. Further, in the present embodiment, the air vents are formed in a staggered pattern on the slope surface, but it is natural that the location and number of the air vents can be appropriately changed according to the purpose of use of the tent sheet.
