  Although the roof of Patent Document 1 is designed to reduce the wind pressure acting on the roof surface by escaping the wind from the wind vent, because the tent sheet etc. is bridged over the frame formed by the pipe, There was a problem that the structural strength of the frame was small and the wind pressure resistance was small.

  Therefore, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a temporary roof structure having a high structural strength and wind resistance.

  The invention according to claim 1 for solving such a problem is a gable-shaped temporary roof structure installed above the building under construction, and the ridge member and the ridge member along the ridge member A purlin member disposed on the side of the ridge member, an eaves member disposed on the eaves side along the purlin member, a rafter member extending in a direction intersecting the ridge member, and a vinyl film covering the roof surface And.

The agricultural vinyl material is, for example, a polyolefin film, a polyvinyl chloride film, a fluororesin film, or the like. The agricultural vinyl material is not limited to the above material, and may be other materials. According to such a structure, since the extension amount of a vinyl film is large and it is hard to tear, a wind-resistant pressure can be made still larger.

  Further, in the temporary roof structure according to the present invention, a short fixing pipe is wrapped around the tension wire of the rafter member, and the vinyl film has a C-shaped fixing member that surrounds the fixing pipe. And it is preferably fixed by being sandwiched between the hollow pipe or the outer peripheral surface of the fixing pipe. According to such a configuration, the vinyl film can be easily fixed to the rafter member.

  Moreover, in the temporary roof structure which concerns on this invention, it is preferable that the said tension | tensile_strength wire of the said ridge member is tensioned in the state in which both ends were connected to the foundation. According to such a configuration, since the ridge member is securely fixed, it is possible to prevent the temporary roof structure from being blown up.

  Further, in the temporary roof structure according to the present invention, the upper end portion of the tension wire of the rafter member is locked to the ridge member pulled upward, and the lower end portion of the tension wire of the rafter member is the building. Those locked to a scaffold formed around the object are preferred. According to such a configuration, the rafter member is arranged at a desired angle and is tensioned.

  According to the present invention, it is possible to increase the structural strength of the frame and increase the wind resistance of the temporary roof structure.

  The vinyl film 60 is a member that covers the roof surface. Specifically, the vinyl film 60 covers the roof surface surrounded by the main building member 20, the eaves edge member 30, and the rafter members 50 and 50 at both ends. The vinyl film 60 is made of an agricultural vinyl material (a sheet-like film used in an agricultural greenhouse), for example, an agricultural polyolefin film, a polyvinyl chloride film, or a fluororesin film. The agricultural vinyl material is not limited to the above material, and may be other materials. The vinyl film 60 is lightweight, has high flexibility and durability, and has high wind resistance (wind pressure resistance). The vinyl film 60 can withstand a maximum wind speed of 50 m / s when combined with the base frame. The vinyl film 60 is transparent. The vinyl film 60 may be colored with a light shielding property. The vinyl film 60 is divided into an upper film 61 that covers the gradient upstream side of the roof surface, and a lower film 62 that covers the gradient downstream side of the roof surface. The upper film 61 covers a portion surrounded by the purlin member 20, the intermediate member 40, and the rafter members 50 and 50 at both ends. The lower film 62 covers a portion surrounded by the intermediate member 40, the eaves member 30, and the rafter members 50 and 50 at both ends. The downstream end of the upper film 61 and the upstream end of the lower film 62 are partially polymerized. In the superposition part, the upper film 61 is located on the upper side of the lower film 62, so that rainwater that has flowed through the upper film 61 flows on the lower film 62 and does not soak inward from the gaps in the superposition part. It has become. During a strong wind, a gap is generated between the upper film 61 and the lower film 62 so that air from the lower side escapes to the outside.

  As shown in FIGS. 4A and 3, the vinyl film 60 is fixed to the purlin member 20 via a fixing member 63 having a C-shaped cross section. The fixing member 63 is flexible and has a circular arc shape with a central angle of 180 degrees or more. The inner diameter of the fixing member 63 is equal to the outer diameter of the hollow pipe 21. The vinyl film 60 is laid on the upper side of the hollow pipe 21. The fixing member 63 sandwiches the hollow pipe 21 together with the vinyl film 60 from the outside. That is, the vinyl film 60 is fixed by being sandwiched between the hollow pipe 21 and the fixing member 63. Three fixing members 63 are provided at predetermined intervals between the adjacent rafter members 50 and 50. The number of fixing members 63 is appropriately set according to the length of the purlin member 20. 3 shows a cross section of a portion where the vinyl film 60 is fixed by the fixing member 63, and a right half shows a cross section of a portion where the fixing member 63 is not provided.

  The vinyl film 60 is also fixed to the eaves member 30 and the intermediate member 40 via the fixing member 63, as in FIG. On the intermediate member 40, the upper film 61 and the lower film 62 are superposed, and the upper film 61 and the lower film 62 are put together and sandwiched between the hollow pipe 41 and the fixing member 63. ing.

  When the vinyl film 60 is fixed to the rafter member 50, as shown in FIG. 4B, a short fixing pipe 64 is wrapped around the tension wire of the rafter member 50. The fixing pipe 64 is obtained by cutting an iron pipe for a greenhouse in a predetermined length, and is approximately equal to or slightly longer than the length of the fixing member 63. The outer diameter of the fixing pipe 64 is equal to the inner diameter of the fixing member 63. The vinyl film 60 is laid on the upper side of the fixing pipe 64. The fixing member 63 sandwiches the fixing pipe 64 together with the vinyl film 60 from the outside. That is, the vinyl film 60 is fixed by being sandwiched between the fixing pipe 64 and the fixing member 63. One fixing member 63 and one fixing pipe 64 are provided in each of an intermediate portion between the purlin member 20 and the intermediate member 40 and an intermediate portion between the intermediate member 40 and the eaves member 30.

  As shown in FIGS. 2 and 5, the roof member 70 is a member that blocks between the ridge member 10 and the purlin member 20 (a portion where the vinyl film 60 is not laid). The roof member 70 can be opened and closed outward by wind pressure. The roof member 70 is made of a lightweight resin material such as plastic, and has a plate shape with an inverted V-shaped cross section. A plurality of roof members 70 are formed by being divided in the longitudinal direction of the ridge member 10. The top portion 71 of the roof member 70 is locked to the upper portion of the ridge member 10 and is tied to the ridge member 10 with a string 72. The fold of the top portion 71 of the roof member 70 is configured to expand when a predetermined or higher wind pressure acts on the inner surface of the roof member 70 from below (see FIG. 5). Specifically, when the wind pressure acts in the direction of the white arrow in FIG. 5 and the roof member 70 at the top thereof is opened, a wind vent hole is formed in a portion indicated by a dot. The lower end portion of the roof member 70 is overlapped with the upper end portion of the vinyl film 60. In the overlapping portion, the roof member 70 is positioned above the upper film 61, and rainwater that has flowed through the roof member 70 flows on the upper film 61. A hole (not shown) through which the string 72 passes is formed in the top 71 of the roof member 70.

  Although not shown, a reinforcing band made of a vinyl material is bridged between the purlin member 20, the intermediate member 40, and the eaves member 30. The reinforcing band is arranged so as to sandwich the vinyl film 60 in a tensioned state, and reduces the flutter of the vinyl film 60 due to wind. The material of the reinforcing band is not limited to a vinyl material, and may be an elastic member such as rubber.

  Next, the construction method of the temporary roof structure 1 having the above configuration will be described. As shown in FIG. 6, after the foundation 3 is constructed, the temporary roof structure 1 is installed on the foundation 3. The temporary roof structure 1 is laid in a flat state that is not inclined. When laying the temporary roof structure 1, first, the ridge member 10 is installed, and then the rafter members 50, 50, 50 are installed crossing each other. Thereafter, the purlin member 20, the intermediate member 40 and the eaves member 30 are installed on the rafter members 50, 50, 50. At this time, both ends of each member are not fixed and are in a state capable of being lifted. Thereafter, the vinyl film 60 is laid and fixed on the purlin member 20, the intermediate member 40, the eaves member 30, and the rafter member 50. The vinyl film 60 is laid in a slack state in the gradient direction. At this time, the vinyl film 60 is fixed only to the purlin member 20, the intermediate member 40, and the eaves member 30 through the fixing member 63, and is not fixed to the rafter member 50.

  As shown in FIG. 7, the vertical wire 13a is attached to the ridge member 10, and the horizontal rope 14 is bridged on the upper end. Both ends of the horizontal rope 14 are lifted, and the ridge member 10 is lifted. At this time, the rafter member 50 is locked to the ridge member 10 and the central portion is lifted. Both ends of the rafter member 50 are sent out by the length lifted while being held at a constant pressure. As the rafter member 50 is lifted, the purlin member 20 and the intermediate member 40 are also lifted. When the rafter member 50 is inclined to a predetermined gradient, the vinyl film 60 is not loosened and is in a state of being stretched flat. Here, the vinyl film 60 is fixed to the rafter member 50 via the fixing member 63. The rafter member 50 is provided with a fixing pipe 64 in advance. The fixing pipe 64 is moved to a predetermined position (an intermediate portion between the main building member 20 and the intermediate member 40 and an intermediate portion between the intermediate member 40 and the eaves member 30), and the fixing member 63 is fixed from above the vinyl film 60. Attach to 64.

  Further, the roof member 70 is installed before and after the fixing of the vinyl film 60. The roof member 70 arrange | positions the top part 71 on the ridge member 10, and binds it to the ridge member 10 from the lower side using the string 72 (refer FIG. 2 and FIG. 5). Thereby, the roof shape of the temporary roof structure 1 is completed.

  Thereafter, the temporary roof structure 1 is lifted to a predetermined height, the suspension wire 13b is inserted into the upper end of the vertical rope 13a, and the suspension wire 13b is connected to the scaffolds 2 on both sides (see FIG. 1). Thus, the temporary roof structure 1 is fixed to the scaffold 2 and the construction of the temporary roof structure 1 is completed.

  Next, a state in which the vinyl films 60 of the temporary roof structure 1 are bundled during a strong wind such as a typhoon will be described. When a strong wind is expected, as shown in FIG. 8, the fixing member fixed to the rafter member 50 is removed, and the tension wires 22 and 42 of the purlin member 20 and the intermediate member 40 are released. Then, the vinyl film 60 is folded while the purlin member 20 and the intermediate member 40 are moved toward the eaves member 30 side. The purlin member 20, the intermediate member 40, the eaves member 30, and the vinyl film 60 are bundled with a rubber band (not shown) and fixed to the scaffold 2. According to this embodiment, the typhoon curing of the temporary roof structure 1 is completed by the simple operation as described above. Moreover, it is easy to return to the original state.

  According to the temporary roof structure 1 of the present embodiment, the tension wires 12 (22, 32, 42) of the ridge member 10 (the purlin member 20, the eaves member 30, the intermediate member 40) resist the bending load, so that the hollow pipe 11 (21, 31, 41) becomes difficult to buckle. Therefore, the structural strength of the frame can be increased, and the wind pressure resistance of the temporary roof structure 1 can be increased.

  Moreover, since the roof member 70 that can be opened and closed by wind pressure is provided between the ridge member 10 and the purlin member 20, the wind from the lower side can be released to the outside by opening the roof member 70 in a strong wind. . Therefore, the wind resistance can be further increased. When the roof member 70 is opened, wind blows from the lower side, so that rainwater rarely blows into the building side.

  Furthermore, since the vinyl film 60 is made of an agricultural polyolefin-based film, a polyvinyl chloride film, or a fluororesin film, the amount of the vinyl film 60 that extends is difficult to break. Therefore, wind resistance can be further increased and durability can be increased. In addition, the generation of flapping noise due to wind can be reduced. In addition, the vinyl film 60 is divided into an upper film 61 and a lower film 62, and in strong winds, a gap is formed in the overlapping portion between the upper film 61 and the lower film 62, so that the wind can escape. The wind pressure can be further increased.

  Further, as the hollow pipe 21 of the purlin member 20, the hollow pipe 41 of the intermediate member 40, the hollow pipe 31 of the eaves member 30, and the fixing pipe 64, iron pipes for greenhouses are used. Furthermore, since the fixing member 63 is also used for a greenhouse, the vinyl film 60 can be easily fixed. Further, since the fixing member 63 and the vinyl film 60 can be easily removed, each member can be reused.

  Furthermore, since the tension wire 12 of the ridge member 10 is tensioned in a state where both ends are connected to the foundation 3, the ridge member 10 is securely fixed, so that the temporary roof structure 1 can be prevented from being blown up. In this embodiment, both ends of the tension wire 22 of the purlin member 20, the tension wire 32 of the eaves member 30, and the tension wire 42 of the intermediate member 40 are also connected to the foundation 3, so that the fixing strength of the temporary roof structure 1 is further increased. it can.

  Further, the upper end portion of the tension wire of the rafter member 50 is locked to the ridge member 10 pulled upward, and the lower end portion of the tension wire of the rafter member 50 is locked to the scaffold 2 formed around the building. Therefore, the rafter member 50 can be arranged at a desired angle.

  As mentioned above, although the form for implementing this invention was demonstrated, this invention is not limited to the said embodiment, In the range which does not deviate from the meaning of this invention, a design change is possible suitably. In the said embodiment, although the transparent film was employ | adopted for the vinyl film 60, it is good also as a colored thing. In this way, it is possible to block sunlight and take measures against heat stroke, and improve the working environment.

  Moreover, in the said embodiment, although the both ends of the tension | tensile_strength wire 21 of the purlin member 20 are being fixed to the foundation 3, if it is a place which can be fixed reliably, you may fix to another part. For example, both ends of the tension wire 21 may be connected to the scaffold 2 tightly coupled to the foundation 3.
