Description

  The present invention relates to a laying method for laying a roof sheet material such as a vinyl sheet on a structure, and a temporary fastener for laying used in the laying.

  “Plastic houses”, which are widely used mainly by farmers, are generally fixed pipe materials (also called straight pipes) that run several arch-shaped pipe materials upright on the ground surface and run horizontally. ) To form a skeleton. A greenhouse is completed by laying a roof sheet so as to cover the skeleton in accordance with the time when the cultivation of the product is started. At the end of the season, usually only the sheet material is removed leaving the skeleton. It may be cultivated with the sheet material laid throughout the year, but the sheet material will be removed at the end of the season to prevent snow damage in winter and deterioration of the sheet material when it is not in use (decrease in transparency). Is normal. The greenhouse is useful for protecting a plant to be cultivated from damage caused by wind and snow, animals, etc., maintaining a relatively high indoor temperature against the outside air, and providing a comfortable farming environment.

  Here, since a polyvinyl chloride film is mainly used as the sheet material, it is generally called “vinyl house”. However, the sheet material is not limited to vinyl, and nowadays more durable polyolefin. System films and fluororesin films are also used. As the skeleton part, pipe materials (generally galvanized steel pipes) are usually used as described above, but round bars, mold steel materials, wood, etc. may be used instead of pipe materials.

  Covering the structure with a roof sheet covering the structure composed of the constructed skeleton is a very large-scale operation. Aside from extremely small greenhouses, for example, in greenhouses with a length of more than 20 m used for business purposes, the weight of the sheet material covering this is several tens of kilograms. In the laying method, for example, a sheet material is covered from one end in the longitudinal direction so as to straddle the width direction on both sides, and this is sequentially advanced in the longitudinal direction to reach the other end. In addition, in this specification, the extending direction of one arch-shaped pipe material is the width direction of the greenhouse, and the direction perpendicular to the width direction, and several arch-shaped pipe materials are tied in a horizontal direction and fixed. The direction in which the fixing pipe material (straight pipe) runs is referred to as the longitudinal direction of the greenhouse.

  However, such a conventional sheet material laying method has a problem. The sheet material having a large area is easy to wind, and even a slight wind is difficult to lay because the sheet material is covered with the wind. Also, if the wind blows out during the work, it is necessary to stop the work or start over. Since farming is an important factor in time, it could have an impact on farming if windy or rainy days continued. In the conventional method, since the sheet material is developed sequentially in the longitudinal direction, it is necessary to hold the developed sheet material everywhere, and a large number of people are absolutely necessary. For example, in a greenhouse with a length of 70 meters, it was necessary to carry out 3 to 5 people, and this could become a big bottleneck as the absolute number of agricultural workers decreased.

  In order to deal with such problems, in the prior art, the sheet material is folded in a zigzag shape in the longitudinal direction and placed on a sled-like traveling part, and the traveling part is further mounted on a rail-shaped auxiliary tool provided on the roof skeleton. A method is disclosed in which the sheet material is successively developed in the longitudinal direction while sliding (see, for example, Patent Document 1). However, according to this method, it is disadvantageous in terms of cost, such as providing a rail-shaped auxiliary part for the skeleton part, and further preparing a large traveling part that straddles the skeleton part, There was a problem such as the need to construct the skeleton part fairly firmly.

  As described above, the present invention improves the above-described conventional method for laying a sheet material for a greenhouse, can be carried out more easily and efficiently, can be performed even in the presence of a certain amount of wind, and has a small amount. An object of the present invention is to provide a sheet material laying method that can be performed even by a number of people, and a temporary fastener for laying that can be used in the method.

  In the present invention, when laying a sheet material on a skeleton part of a structure, the sheet material is first properly folded into a bundle extending in the longitudinal direction of the greenhouse without sequentially developing the sheet material in the longitudinal direction from the beginning. Then, the folded sheet material bundle is temporarily fixed on the pipe fixing material for the top of the greenhouse skeleton at an appropriate interval by using a temporary fixing tool, and then the sheet material is formed on both sides in the width direction of the greenhouse. In particular, the following contents are included.

  That is, one aspect according to the present invention is a sheet material laying method for laying a sheet material for a roof of a structure on a skeleton part of the structure, wherein the skeleton part is perpendicular to the ground surface. A plurality of arch-shaped first struts extending in the width direction standing upright and horizontally extending along a longitudinal direction orthogonal to the width direction to connect the plurality of first struts and reinforce them. A plurality of second struts including a ridge strut disposed at the top of the arch shape, and the laying method is configured such that the sheet material is preliminarily placed on the ground or on the skeleton part in the center in the width direction. The sheet material placed in the longitudinal direction is placed on the ridge column along the longitudinal direction, and the sheet material placed in the longitudinal direction is stretched over the entire length in the longitudinal direction. Are temporarily fixed to the ridge column at predetermined intervals, and the temporarily fixed A plurality of horizontal ropes extending in the width direction of the skeleton part are covered at predetermined intervals in the longitudinal direction so as to cover the toe material, and at least a part of the plurality of horizontal ropes has a margin near the ground surface on both sides in the width direction. Temporarily fixing and releasing the temporary fixing of the temporarily secured sheet material to release the sheet material from the grunged state, while the upper portion of the skeleton portion is placed between the skeleton portion and the lateral rope. And after all the sheet material is developed in the longitudinal direction, all the horizontal ropes including the lateral rope temporarily fixed with a margin are finally tightened and fixed. Regarding the method.

  The step of folding the sheet material from both sides toward the center in the width direction and rounding the sheet material from the both sides toward the center in the width direction of the sheet material, and then zigzag the sheet material from both sides, respectively, They can be rounded to face each other. Further, the step of temporarily fixing the sheet material placed on the ridge column with the ridge column at a predetermined interval in the longitudinal direction is a temporary fixing tool for laying that is lifted from the ground surface toward the ridge column, or in advance With the temporary fixing tool for laying temporarily fixed to the ridge post, the ridge post and the sheet material can be tied together and temporarily fixed. The structure may be a greenhouse.

  Furthermore, the step of temporarily fixing a plurality of horizontal ropes covering the temporarily fixed sheet material at a predetermined interval in the longitudinal direction is configured such that one end of each of the horizontal ropes is a ground surface in one width direction of the skeleton part. The other ends of the horizontal ropes are previously connected to the longitudinal ropes extending in the longitudinal direction, the vertical ropes are passed over the temporarily fixed sheet material, and the other ones in the width direction of the skeleton portion are connected. After moving to the side, the other end of the horizontal rope can be removed from the vertical rope and temporarily fixed near the ground surface of the skeleton on the other side.

  According to another aspect of the present invention, when the sheet material constituting the roof of the structure is laid on the skeleton portion of the structure, the ridge column is located at the top of the skeleton portion and extends in the longitudinal direction of the structure. A temporary fixing tool for laying a sheet material for bundling and temporarily fixing together the sheet material that is folded and rolled from both sides in the width direction orthogonal to the longitudinal direction and placed on the ridge post, A handle extending between the hand-held end and the operating end, and a holding portion fixed to the operating end of the handle, holding the ridge straight pipe and the sheet material together, and temporarily fixing the sheet material to the ridge straight pipe The holding part is provided with the release mechanism which cancels | releases temporary fixation by the said holding part from the hand-held end part side of the said handle | pattern, It is related with the temporary stopper characterized by the above-mentioned. The release mechanism can be composed of either a flat fastener or a lock mechanism and a release string that is released by pulling the release mechanism from the hand-held end side. Or it may replace with the said cancellation | release mechanism and may be comprised from the U-shaped elastic member which has the curved surface which the said holding part expands upwards.

  Other aspects of the temporary fastener for laying the sheet material include a band-shaped main body, an elastic ring attached to the main body at one end in the longitudinal direction of the main body, and the other end in the longitudinal direction of the main body. A release lever that is pivotally attached to the main body, a release string that is attached to the release lever and that is operated to release the release lever from a position away from the release lever, and the main body in a direction perpendicular to the longitudinal direction of the main body The elastic ring is a temporary fixing state of the sheet material by bundling together the sheet material and the ridge strut in the sag state and hanging on the release lever, By pulling, the release lever can be rotated to release the temporarily fixed state. An elastic support member that holds the ridge column and holds the ridge column may be further provided at a portion of the main body that faces the ridge column.

  By carrying out the present invention, the sheet material laying operation to the greenhouse is greatly improved by using only a simple temporary fastener, and first, the number of persons can be reduced to about half that of the prior art (that is, Two people in a 70m-class greenhouse), work can be performed even in the presence of a certain amount of wind that could not be done in the past, and effects such as greatly improved work efficiency can be obtained.

  A method for laying a roof sheet material covering a structure such as a greenhouse according to the first embodiment of the present invention will be described with reference to the drawings. In the following description, a “vinyl house” will be described as an example. However, the application of the present invention is not limited to this. For example, a sheet material is laid in a form covering a skeleton such as a greenhouse, a garden house, or a terrace. It can be applied to other structures. Further, the sheet material is not limited to “vinyl”, and other sheet materials as described above can be used as well. Furthermore, although expressions such as “pipe material” and “(building) straight pipe” are used for the skeleton, other structural materials as described above may also be used.

  FIG. 1 shows the preparation status of the sheet material laying method according to the present embodiment. In the figure, the skeleton 10 of the greenhouse 1 is constructed by a conventional technique. The skeleton 10 includes a plurality of arch-shaped first struts 11 (hereinafter referred to as “pipe materials”) that are erected perpendicularly to the ground surface, and an arch-shaped pipe material that extends in a horizontal direction perpendicular to the first support columns 11. 11 and a plurality of second support columns 12 (hereinafter referred to as “straight pipes”). The front end of the arched pipe material 11 of the skeleton 10 is a commercial standard product with various dimensions from 3.6 m to 9 m, and the thickness of the pipe material of both struts 11 and 12 is various dimensions from 19 mm to 40 mm. There is. However, other dimensions can be made by custom order. The length of the skeleton part 10 in the longitudinal direction is usually several tens of meters, the arch-shaped pipe material 11 is also several tens of pipes at intervals of 50 cm inside and outside, and the straight pipes 12 (12a to 12c) are also arranged at the top. Although composed of a large number (5-10) including the tube 12c, this is simplified in the drawing and only a small number is displayed. In addition, a coupling bracket is used for a coupling portion between the pipe material 11 and the straight pipe 12, but this is omitted in the drawing. On the side of the skeleton 10, a reinforcing rope 20, a sheet material 30, and a laying temporary stopper 40 are prepared.

  The reinforcing rope 20 includes a plurality of horizontal ropes 21 (also referred to as “house bands”) arranged at regular intervals, such as every 1 m, and a vertical length that extends over the entire length of the skeleton 10 in the longitudinal direction. It is composed of a rope 22. One end of each lateral rope 21 is connected to a straight pipe 12a (or a band stopper pipe (not shown) provided exclusively for stopping the lateral rope 21) close to the ground surface on one side of the greenhouse 1, and the other end is It is tied to the vertical rope 22. Since the horizontal rope 21 has a sufficient length that extends to the opposite side surface across the greenhouse, it is preferable that the middle portion is rounded as shown so as not to be entangled with each other.

  The sheet material 30 generally has a plate thickness of 0.05 mm to 0.15 mm. When the width dimension of the greenhouse (the opening dimension of the pipe material 11) is 7.2 m and the total length in the longitudinal direction is 70 m, the weight of the sheet material 30 having a thickness of 0.075 mm is about 70 kg. In the present embodiment, the sheet material 30 is previously rolled and arranged as shown. The rounded situation is illustrated in FIGS. 2 (a) and 2 (b). In the situation shown in FIG. 2A, the sheet material 30 is folded in a zigzag manner from both the left and right sides toward the center line 31 (the phantom line shown by the broken line) extending in the longitudinal direction, and then the final part. 2 and 3 are rounded so as to face each other. In the situation shown in FIG. 2B, the sheet material 30 is rolled and folded so as to face each other toward the center line 31. In the present specification, as shown in FIGS. 2 (a) and 2 (b), folding one sheet material 30 from the left and right with respect to the center line 31 is "tacking process", and the folded state is "tacking state". Shall be called. The sagging states shown in FIGS. 2A and 2B are merely examples, and the sheet material 30 that is finally folded may be folded so as to be easily developed on the skeleton part later. In the example shown in the figure, the winding method shown in FIG. 2A seems to be better than the winding method shown in FIG. Further, the sheet material 30 after the drilling process is preferably handled in the vertical direction as shown in FIG. 2, but can also be handled in the upside down direction. By performing this dragging process on the sheet material 30, the sheet material is not blown away even if a certain amount of wind blows. In addition, the sheet material 30 subjected to the scouring treatment can be temporarily bound at both ends or at any intermediate position in the longitudinal direction in this state as necessary.

  Returning to FIG. 1, a plurality of laying temporary fasteners 40 (hereinafter also simply referred to as “temporary fasteners”) are arranged on the rightmost side of the drawing. The structure and function of the temporary fastener 40 will be described in detail later.

  FIGS. 3A and 3B show a part of the procedure for laying the sheet material 30 with the sheet material 30 prepared as described above and the other elements in the line. First, in FIG. 3A, one end of the sheet material 30 subjected to the punching process is grasped and lifted to one end in the longitudinal direction of the skeleton part 10 and placed on the central ridge straight pipe 12c. Here, the site | part is temporarily fixed using the temporary fixing tool 40 for laying so that the said sheet | seat material 30 may not slip down. The temporary stopper 40 may receive the thing lifted from the bottom up, and may be previously hooked on the ridge straight pipe 12c. During this time, one person can lift up one end of the sheet material 30 from below, and one person can receive it and lift it up. Furthermore, if necessary, it is not impossible to perform a one-person operation by hooking the temporary stopper 40 in advance on the ridge straight pipe 12c and lifting the sheet material 30 while lifting it.

  Next, in FIG. 3B, the remaining sheet material 30 is sequentially pulled up and placed on the ridge straight pipe 12c, and the sheet material 30 is sequentially rectified by using a temporary fastener 40 at predetermined intervals (for example, 5 m). Temporarily fasten to the tube 12c. Also in this case, one person can lift up the temporary fixing tool 40 sequentially from the bottom, and the other person picks it up and temporarily fixes it. It is also possible to do this. During this time, even if there is a certain amount of wind, the sheet material 30 is subjected to the scouring process, and since it is temporarily fixed using the temporary fixing tool 40 one after another, the sheet material 30 is exposed to the wind. , Don't fall apart. By repeating the above operation, the sheet material 30 is temporarily fixed on the ridge straight pipe 12a by the temporary fixing tool 40 over the entire length in the longitudinal direction, as shown in FIG.

  In the state shown in FIG. 3B and FIG. 2, the ridge straight pipe 12 c is drawn on the upper side of the pipe material 11. In this state, the sheet material 30 is placed directly on the ridge straight pipe 12c over the entire length in the longitudinal direction. However, in the skeleton part 10 of the greenhouse, the ridge straight pipe is usually below the pipe material 11. 12c is arranged. In this case, the sheet material 30 extending in the longitudinal direction is placed on the pipe material 11 locally apart from the ridge straight pipe 12 c in a portion straddling the pipe material 11. However, when viewed through the entire greenhouse, the sheet material 30 is placed on the ridge officer 12c, so in this specification, the sheet material 30 is locally built in this way. Even if the pipe material 11 on the straight pipe 12a may be straddled, the sheet material 30 is expressed as being “placed on the building straight pipe 12c”.

  In this embodiment, the sheet material 30 is preliminarily processed on the ground. However, when the wind is in a breeze or the like, the sheet material 30 is received as it is from below and the sheet material 30 is processed on the skeleton 10. It is also possible to temporarily fix in the longitudinal direction sequentially. Further, it is preferable in the work that the order of the temporary fixing starts from one end in the longitudinal direction as shown in the figure, but may be started from an arbitrary position in the longitudinal direction as necessary.

  FIG. 4 shows a temporary fixing method using the temporary fixing tool 40 for laying. In FIG. 4A, the sheet material 30 in a drilled state is placed on the ridge straight pipe 12 c of the skeleton part 10. The temporary fastener 40 is lifted from below using the handle 44, and the main body portion 41 of the temporary fastener 40 is abutted against the lower side of the building straight pipe 12c. An elastic ring 43 for temporary fixing made of an elastic body such as rubber is attached to one end of the main body 41, and this is pulled upward to cover the sheet material 30 that has been subjected to the scouring process. As shown in b), it is locked by being hooked on a release lever 42 provided on the other end side of the main body 41. Thereby, the sheet material 30 is completely fixed on the building straight pipe 12c. The configuration of the temporary stopper 40 including the release lever 42 will be described in detail later in the second embodiment.

  Next, FIGS. 5A to 5C show operations in the latter half of the sheet material laying method. First, in FIG. 5A, the reinforcing rope 20 (see FIG. 1) disposed on one side surface of the skeleton part 10 in a state in which the sheet material 30 is temporarily fixed on the ridge straight pipe 12 c is indicated by a broken line. As indicated by the arrows, the upper part of the skeleton part 10 and the sheet material 30 are moved to the opposite side surface. Since one end of each horizontal rope 21 is already connected to the straight pipe 12a (or band stop pipe) on the front side surface of the drawing as described above, the skeleton 10 The frame portion 10 and the sheet material 30 can be covered simultaneously with the plurality of horizontal ropes 21 by dodging the upper side of the frame to the side surface on the opposite side in the width direction. Next, the other end of each horizontal rope 21 is removed from the vertical rope 22 on the opposite side surface and tied to a straight pipe 12b (or a band stopper pipe not shown) near the ground surface on the opposite side surface of the skeleton 10. At this time, since the sheet material 30 is not yet developed, the horizontal rope 21 is not tied tightly, but tied with a certain margin. As a result, the sheet material 30 on the skeleton part 10 and the ridge straight pipe 12 c is covered with the plurality of horizontal ropes 21. The horizontal rope 21 is efficiently covered at a stretch using the vertical rope 22 as described above, but it is of course possible to cover the horizontal rope 21 individually one by one. Further, when tying the horizontal rope 21 to the straight pipe 12b on the opposite side surface, it is not necessary to tie all the horizontal ropes 21 to the straight pipe 12b at this stage depending on the state of the wind. It may be tied to.

  Next, in this state, as shown in FIG. 5 (b), the string material 30 which is temporarily fixed by tying the sheet material 30 at one end in the longitudinal direction of the greenhouse is unfastened, and further, the laying temporary stopper 40 is disposed in the longitudinal direction. While removing in order, the sheet material 10 that was in the drilled state is sequentially developed on both sides in the width direction of the skeleton 10. The temporary fastener 40 can be removed remotely from the ground inside the greenhouse as will be described later. The removal of the temporary fastener 40 and the development of the sheet material 30 on both sides in the width direction can be performed by two people. The sheet material 30 is unfolded in the gap between the horizontal rope 21 and the skeleton part 10 tied with a margin. When the removal of all the temporary fasteners 40 and the development of the sheet material 30 are completed, the entire upper part of the skeleton 10 is covered with the roof sheet material 30 as shown in FIG. After all the deployment is completed, all the horizontal ropes 21 including the horizontal rope 21 that has been loosely tied with a margin earlier are pulled firmly and tightly tied to the straight pipe 12b (or the band stop straight pipe). . It should be noted that the release of the sheet material 30 from the sag state is good in terms of work, as shown in the figure, but it can also be started from an arbitrary position in the longitudinal direction as required.

  In order to complete the greenhouse 1, the sheet material 30, which has a surplus length provided in advance on both end surfaces in the longitudinal direction of the skeleton 10, is hung downward to fix the door frame and the doorway. The sheet material 30 is fixed to the straight pipe 12 using a spring material called Binipet (registered trademark), or a winding sheet is provided at the hem portion for temperature adjustment, as necessary. These operations can be similarly performed in accordance with the prior art.

  In the above method, the remarkable difference between the sheet material laying method according to the prior art and the method according to the present embodiment is that the sheet material 30 is expanded by the reinforcing rope 20 (particularly, the lateral rope 21). It can be done in a state of covering. That is, in the method according to the conventional technique, it is necessary to first develop the sheet material 30, and otherwise, the sheet material 30 cannot be covered with the lateral rope 21. For this reason, on a day with wind, the sheet material 30 was blown away, so that the sheet material laying work could not be performed, and the work had to be interrupted or redone. According to the method according to the present embodiment, it is possible to cover the sheet material 30 with the lateral rope 21 when the sheet material 30 is still in the squeezed state. And since the sheet | seat material 30 is released and developed from the state which was covered with the horizontal rope 21, even if a certain amount of wind blows, the sheet | seat material 30 will not be raised or blown, but a horizontal rope. In other words, the sheet material 30 can be unfolded inside 21 (the gap between the horizontal rope 21 and the skeleton 10).

  Next, a temporary fastener for laying according to a second embodiment of the present invention will be described with reference to the drawings. The temporary fastener has been described with reference to FIGS. 3 to 5 in the previous embodiment, and the details are shown in FIG. In the figure, a temporary fastener 40 for laying includes a band-shaped main body 41, a release lever 42 rotatably attached to one end in the longitudinal direction of the main body 41, and an elastic ring attached to the other end of the main body 41. 43, a handle 44 provided in the main body 40 in a direction orthogonal to the longitudinal direction, and a release string 45 attached to the release lever 42. As shown by the solid line in FIG. 6, a gap is formed between the elastic ring 43 and the main body 41 by hooking the elastic ring 43 to the position of the hook 42a of the release lever 42, and a two-dot chain line is formed between the gaps. As shown, the ridge straight pipe 12c and the sheet material 30 in the drilled state can be fixed.

  The laying temporary fastener 40 configured as described above operates in such a manner that the main body 41 of the temporary fastener 40 is placed under the ridge straight pipe 12c in a state where the sheet material 30 is first placed on the ridge straight pipe 12c. Bump to the side. This operation may be performed by lifting the temporary fastener 40 with the handle 44 from the ground. Next, after an operator on the skeleton 10 grasps the temporary stopper 40 and extends the elastic ring 43 to cover the ridge straight pipe 12a and the sheet material 30, the release lever 42 on the opposite side is replaced with the hook 42a. Hook to the position. Since the release lever 42 is prevented from further rotation by the action of the stopper 42b, the elastic ring 43 is locked in this state. Even if the operator releases his / her hand due to the lock of the elastic ring 43, the temporary stopper 40 is kept in a fixed state, so that the operator moves in the longitudinal direction to the position where the temporary stopper 40 is located. All the necessary number of temporary fasteners 40 are attached by sequentially performing the same operation.

  After the installation of all the temporary fasteners 40 for laying is completed and the reinforcing rope 20 is put thereon, the temporary fasteners 40 are sequentially removed from one side in the longitudinal direction of the greenhouse. The detachment can be easily performed by pulling the release string 45 hanging downward from the release lever 42 on the ground. As indicated by an arrow and a two-dot chain line in FIG. 6, the release lever 42 is rotated by the operation of the release string 45, and the lock of the elastic ring 43 is released. While one person pulls on the ground, the other person may assist the deployment of the sheet material 30 on the skeleton part 10, or both of them may deploy the sheet material 30 in cooperation with the ground. By releasing the lock of the elastic ring 43, the restraint of the temporary fastener 40 is also released and can be freely removed, and the removed temporary fastener 40 is collected on the ground. When removing, the temporary stopper 40 does not fall naturally by holding the handle 44 in advance and operating the release string 45. The release of the elastic ring 43 is not limited to the release lever 42 as shown in the figure, and other methods known in the prior art such as using a link mechanism may be used. The release string 45 is not necessarily a “string” but may be a wire, a rod, or the like.

  An elastic holder 46 indicated by a two-dot chain line in the figure may be provided on the upper side near the center of the main body 41. The elastic holder 46 can fix the temporary stopper 40 to the ridge straight pipe 12a by sandwiching the ridge straight pipe 12a when the main body 41 is abutted against the ridge straight pipe 12c. As a result, the temporary fasteners 40 are fixed to the ridge straight pipe 12a without setting the elastic ring 43, so that, for example, one person previously attaches the necessary number of temporary fasteners 40 to the ridge straight pipe 12a in advance from the ground. It is possible to cope with fixing the sheet material 30 and then fixing the sheet material 30 by climbing onto the skeleton 10. Since the sheet material 30 is located immediately above the ridge straight pipe 12a, it is preferable to consider that the upper end of the elastic holder 46 is covered with a soft material that does not break the sheet material 30.

  FIG. 7 shows another aspect of the temporary fastener according to the present embodiment. The temporary fastener 50 shown in FIG. 7 (a) is fixed to the handle 51 with a screw or the like extending between the handle end that is held and supported by the hand below and the operation end that holds the sheet material. The holding belt 52 is composed of a release belt 53 fixed to the handle 51 with a screw or the like, and a release string 54 attached to the release belt 53. An elastic holder 46 that can be fixed by being abutted against a straight pipe (not shown) is an option. The holding belt 52 and the release belt 53 may be an elastic body that can expand and contract, or may be a non-elastic body made of cloth or the like. Flat fasteners 56 a and 56 b such as Velcro (registered trademark) are provided on the surfaces of the free ends of the holding belt 52 and the release belt 53 that are pinned to each other. The operation of the temporary fastener 50 configured as described above is basically the same as that of the temporary fastener 40 described above. The temporary fastener 50 lifted from below is received on the skeleton of the greenhouse, and the holding belt. The sheet material on the straight pipe is wound around 52 and wound, and the flat fastener 56a is pressed against the flat fastener 56b on the release belt 53 side to complete the temporary fixing of the sheet material. When releasing, the engagement of the flat fasteners 56a and 56b can be easily released by pulling the release string 54 from the ground.

  The temporary fixing tool 60 shown in FIG. 7 (b) is basically the same, and instead of the flat fasteners 56a and 56b shown in FIG. 7 (a), the insertion tool 66a at the tip on the holding belt 62 side and the release belt 63 side. A one-touch buckle mechanism comprising a buckle 66b is provided. This buckle mechanism is constructed in the same manner as an aircraft safety belt, and is easily fixed by inserting the insertion tool 66a into the buckle 66b when fixed, and attached to the cover plate of the buckle 66b when released. The release string 64 can be easily released by pulling. Although not included in the drawing, if either the holding belt 62 side or the release belt 63 side includes a mechanism capable of adjusting the belt length similar to the safety belt of an aircraft, the sheet material to be bundled The belt length can be adjusted according to the size, which is convenient.

  The structure of the temporary fastener shown in FIGS. 7A and 7B is an example. Generally, the temporary fastener is fixed to the handle extending between the grip end and the operation end and the operation end of the handle. A holding part such as a belt that winds the ridge straight pipe and the sheet material together to temporarily fix the sheet material to the ridge straight pipe, and the holding part is remotely connected to the handle holding part side of the handle, etc. What is necessary is just to be comprised so that the cancellation | release mechanism which can be cancelled | released.

  8A and 8B show still another aspect of the temporary fastener. 8A includes a handle 71, a pair of holding arms 72 and 73 that are rotatably attached to the handle 71 as indicated by a broken line and a solid line, and each holding arm 72 and 73. And a release string 74 that is operably attached thereto. The holding arms 72 and 73 can be made of, for example, plastic or aluminum. The release string 74 is tied to the holding arms 72 and 73 and extends from the operating end of the handle 71 through a cavity opened inside to the outside from the other hand-held end. A lock mechanism (not shown) is provided in the middle, and is configured to prevent the release string 74 from moving when a load is applied. For this locking mechanism, for example, an existing technique similar to that provided in an opening / closing string of a window blinder can be used. As shown by the solid line in the figure, the temporary fastener 50 constructed as described above is lifted from below with the upper ends of the holding arms 72 and 73 open, and the ridge straight pipe and the sheet material thereon are moved to both sides. The holding arms 72 and 73 are brought into a closed state indicated by broken lines by pinching them and pulling the release string 74. In this state, the lock mechanism locks the release string 74, and both holding arms 72 and 73 temporarily fix the sheet material sandwiched with the ridge straight pipe. When releasing, the release string 74 is once pulled from the ground to release the lock of the lock mechanism, and thereafter, the holding arms 72 and 73 are opened by their own weights, and the temporary fixation can be released. The above-mentioned locking mechanism is merely an example. For example, a spring-type lock pin or the like is provided at the engaging portion of both holding arms 72 and 73, and when releasing, the lock pin is pulled from below with a release string. Other techniques known in the art may be used.

  The temporary fastener 80 shown in FIG. 8B has a further simplified structure, and here, a substantially U-shaped holding arm 82 that is expanded upward is attached to the handle 81. As shown in the drawing, it is preferable that a bulging portion for holding the sheet material is provided at an intermediate portion on both sides of the holding arm 82 extending in a U shape so as to increase the holding force. In this aspect, the holding arm 82 is formed so as to be openable and closable by an elastic material having an appropriate spring force, whereby the release string in the other aspects shown so far can be abolished. When the temporary fastener 80 is attached, the sheet material on the ridge straight pipe is sandwiched from below using the expanded curved surface of the holding arm 82. At this time, the holding arm 82 that has temporarily expanded due to elasticity closes again with a spring force after dodging the sheet material, and holds the sheet material sandwiched from both sides. At the same time, the temporary stopper 80 itself is temporarily fixed by the sandwiched sheet material. Conversely, when removing, the handle 81 can be easily removed using the spring force by lowering the handle 81 from below. As described above, in the example shown in FIGS. 8A and 8B, the upper portion is kept open without completely winding the sheet material with a holding member such as a belt in order to temporarily fix the sheet material. It shows that the sheet material can be temporarily fixed even with the arm. In addition, by adopting such a form, the temporary fastener can be attached by one operator from the lower side by one person with the handle holding end side.

  The sheet material laying method and the temporary fastener for laying according to the present invention can be widely used in industrial fields such as agriculture, landscaping, building, building material manufacturing, and sales.
