Description

The present invention relates to a wire fixing structure for connecting and fixing an intersecting portion between a wire and a long rigid body member. The present invention also relates to an eaves structure of a greenhouse building and a greenhouse building having a tensile structure provided with eaves.

As a greenhouse building for cultivating vegetables, fruits, etc., and growing other plants, a rigid framework constructed by welding or bolting steel columns and beams is generally used. Further, as the roof structure, a truss structure made of steel frame is often used. Such a rigid structure building is described in Patent Documents 1, 2 and 3.

On the other hand, in general, greenhouse buildings do not have eaves. Therefore, in a snowy area, the accumulated snow slides down from the roof surface and accumulates along the outer wall surface. The outer walls of the greenhouse building are lined with translucent vinyl sheets or glass for daylighting. If the outer wall surface is buried in snow, daylighting may be hindered, and the outer wall surface may be damaged and collapse due to snow accumulation. In addition, water may enter the greenhouse.

Patent Document 4 proposes that a rain gutter is arranged along the upper end of the outer wall surface of the greenhouse building, and a watering device is arranged along the rain gutter. By melting the snow on the roof by sprinkling water and letting it flow along the rain gutter, the harmful effects caused by the snow under the eaves of the greenhouse building are prevented.

The present inventor has proposed a building with a tensile structure suitable for use as a greenhouse building, which can be constructed at a low cost, can be easily expanded and dismantled, and can maintain a sufficient lighting rate (international application number: PCT). / JP2016 / 074236). In a building with a tension structure, a large number of wires are laid vertically and horizontally in a tensioned state between wall structures in which horizontal members are hung on vertically erected columns. Only compressive force acts on the columns, and almost no bending stress is generated on the horizontal members.

In a greenhouse building having such a tension structure, wires are stretched vertically and horizontally, a film stopper is placed between them, and a translucent vinyl film or the like is stuck. Therefore, unlike the conventional case, it is necessary to mutually fix the wire and the film stopper which is a rigid body member at the intersection thereof. Conventionally, a fixture or a fixing structure capable of easily fixing a wire to a rigid body member with good workability has not been proposed.

In addition, in greenhouse buildings, eaves should be provided to prevent rain, snow, etc. from directly hitting the outer wall surface covered with translucent film, glass, etc., and to avoid the harmful effects of snow under the eaves. desirable. In order to attach the watering device described in Patent Document 4 to a greenhouse building, it is necessary to provide a dedicated mounting portion and to reinforce the watering device so as to withstand the weight of the watering device. Therefore, it is not practical not only in a greenhouse building having a tensile structure but also in a greenhouse building having a normal structure in terms of strength and cost. In particular, it is not desirable because the part of the eaves equipped with a rain gutter and a watering device obstructs the lighting of the greenhouse.

An object of the present invention is to provide a wire fixing structure capable of fixing a wire to a rigid body member with good workability.

Another object of the present invention is to provide a wire fixing structure capable of fixing a wire to a rigid member such as a film stopper for stopping a translucent film in a greenhouse building having a tension structure with good workability. ..

Furthermore, an object of the present invention is to provide an eaves structure of a greenhouse building that can be easily and inexpensively attached to an existing greenhouse building.

Another object of the present invention is to provide a greenhouse building having a tensile structure having an eaves structure provided simply and inexpensively.

The present invention is a wire fixing structure for connecting and fixing an intersecting portion between a wire and a long rigid body member.
A connector that can be attached to the rigid body member and
A wedge tool capable of fixing the wire to the rigid body member by a wedge effect generated by inserting the wire into a gap formed between the rigid body member and the connecting tool attached to the rigid body member.
It is characterized by having.

Normally, at the intersection of the wire and the rigid body member, the wire is sandwiched, and the metal fittings for fixing are fastened to the rigid body member side with bolts, screws, or the like to fix the wire to the rigid body member. In the present invention, the connecting tool is attached to the rigid body member, and the wedge tool is driven into the gap in a state where the wire is passed through the gap between them. The wire is fixed to the rigid body member by the wedge effect of the wedge tool. By adjusting the driving amount of the wedge tool, it is possible to absorb the dimensional error of each part, so that the wire can be securely fixed. Further, the work of driving the wedge tool is simpler than the work of screwing in a plurality of bolts, screws, etc., and can be completed in a short time.

Here, in order to securely fix the wire to the rigid body member without damaging it, it is necessary to secure a sufficient length of contact area between the wedge tool and the wire along the length direction of the wire. desirable.

Therefore, in the present invention, the wedge tool is provided with a wire pressing surface having a predetermined length. Further, a wire through groove having a predetermined depth is formed on the wire pressing surface. The wire through groove is a groove extending in the insertion direction of the wedge tool. Pass the wire along the wire through groove and drive the wedge tool in this state. As a result, the wire can be reliably pressed by the wire pressing surface, and the wire is not damaged.

Next, the wedge tool
It has a wedge-shaped portion where the distance from the wire pressing surface gradually increases or decreases along the length direction of the wire through groove.
The wedge tool can be inserted into the gap in a posture in which the wire is sandwiched and the wire pressing surface is directed toward the connecting member, and a posture in which the wire is sandwiched and the wire pressing surface is directed toward the rigid body member.

When the wire is stretched in contact with the rigid body member, the wedge tool may be driven into the gap with the wire pressing surface of the wedge tool facing toward the rigid body member. On the contrary, when the wire is stretched away from the rigid body member, the wedge tool is driven into the gap with the wire pressing surface of the wedge tool facing the opposite side to the rigid body member. The wire can be fixed at a position separated from the rigid body member by the thickness of the wedge tool.

For example, when the rigid body member is a film stopper for fixing a plastic sheet, a film, or the like, the sheet or film is attached along the rigid body member. There is a risk that the sheet or film will bend due to wind or the like and hit the wire, causing damage or the like. In such a case, it is desirable to connect and fix the wire and the rigid body member at intervals.

It is also possible to insert another member to press the wire. For example, a wire retainer that can be inserted between the rigid body member and the wedge tool in the gap can be used. In this case, the wire is fixed between the wire retainer and the rigid body member. Since it is not necessary to form a wire pressing surface on the wedge tool, various shapes of wedge tools can be used.

In this case, the wire retainer is provided with a wire pressing surface having a predetermined length, and a wire through groove having a predetermined depth is formed on the wire pressing surface. Further, the wire through groove is a groove extending in the insertion direction of the wedge tool.

The rigid body member to which the wire is fixed may be a member having various shapes such as a groove-shaped cross section and a tubular cross section. In any case, the connector may be attached in a detachable state according to the cross-sectional shape of the rigid body member.

Next, the present invention is an eaves structure of a greenhouse building in which the roof surface and the outer wall surface are defined by a transparent film or panel.
Anchor members buried underground along the outer wall of the greenhouse building,
A plurality of eaves wires that are arranged at predetermined intervals in the horizontal direction along the outer wall surface, project diagonally downward from the upper end side portion of the outer wall surface, and are hooked to the anchor member.
Having a translucent eaves roofing material made of a translucent film or a translucent panel stretched over an eaves wire so as to project from the outer wall surface over a predetermined length. It is a feature.

By providing an eave in a greenhouse building, rain and snow falling from the roof can be separated from the outer wall surface composed of translucent films, panels and the like. This makes it possible to prevent water from entering the greenhouse from the outer wall surface.

Further, in a greenhouse building, a hoisting device or the like operated when opening and closing for ventilation or the like is arranged along the outer wall surface through a skylight or the like provided on the roof surface. An opening / closing window for ventilation is arranged on the outer wall surface. If snow accumulates along the outer wall surface, the hoisting device cannot be operated, and the opening / closing window is filled, making ventilation impossible. By providing the eaves, snow does not accumulate in the lower part of the eaves, so that such an adverse effect can be avoided.

Furthermore, in heavy snowfall areas, snow may accumulate higher than the eaves. Since the snow cover is located away from the outer wall surface depending on the eaves, it is possible to avoid the harmful effect that the bottom of the eaves is blocked by the snow cover.

In greenhouse buildings, long film stoppers extending in the direction orthogonal to the eaves wire are arranged so that the eaves do not obstruct the lighting, and the film stoppers are translucent as roofing materials for eaves. Stick the film. In this case, the film stop material is provided with a film stop groove extending in the length direction thereof, so that a part of the translucent film is inserted into the film stop groove and does not come off from the film stop groove. It is fixed.

In this case, the above-mentioned wire fixing structure can be adopted as the wire fixing structure for connecting and fixing the intersecting portion between the eaves wire and the film stopper.

Here, in a greenhouse building having a tension structure, tension wires for the gable side anchors are laid in a tense state between the upper ends of the front and rear gable side wall frameworks and the ground at predetermined intervals in the left-right direction. Similarly, tension wires for flat side anchors are laid in a tense state between the upper ends of the left and right flat side wall frame frames and the ground at predetermined intervals in the front-rear direction.

Therefore, at least one of these flat-side anchor tension wires and gable-side anchor tension wires can be used as eaves wires. Therefore, the eaves can be provided very easily.

Hereinafter, embodiments of a greenhouse building having a tensile structure to which the present invention is applied will be described with reference to the drawings.

[overall structure]
FIG. 1 is an explanatory view showing a triple-building greenhouse building for strawberry cultivation according to the present embodiment. The triple-building type greenhouse building 1 is equipped with a rectangular gable roof having a length of 12 m in the left-right direction on the gable side and a length of 58 m in the front-rear direction on the flat side, and the height of the building is 4.5 m. 2 (1), 2 (2), and 2 (3) are connected in the left-right direction. In FIG. 1, a part in the front-rear direction is omitted. Further, for the greenhouse building 2 (1) on the left side, the exterior material is omitted and only the skeleton is shown, and for the greenhouse building 2 (2) in the center, the wire for the gable side anchor is omitted. For the greenhouse building 2 (3) on the right side, the exterior materials other than the eaves are omitted from the exterior materials of the outer wall surface.

Since the greenhouse buildings 2 (1) and 2 (3) have basically the same structure, they may be collectively referred to as the greenhouse building 2. The structure of the greenhouse building 2 is basically composed of a single metal pipe and high-tensile, high-strength wire. Specifically, the front and rear gable side wall frameworks 3F and 3B (see FIGS. 5 and 7) are formed by connecting single pipes having the same diameter as columns, horizontal members, etc. by single pipe joints of various forms. , Left and right flat side wall frameworks 4L and 4R (see FIGS. 6A and 6C), and a central framework 5 extending in the front-rear direction at a central position in the left-right direction (see FIG. 6B). .. Further, the roof surface 6 of the greenhouse building 2 (see FIG. 7 (a)) and the ceiling surface 7 below it (see FIG. 7 (b)) have wires 11 to 14 having a constant pitch in the front-rear direction and the left-right direction. It is formed by stretching it so that it is in a predetermined tension state.

As the wire, for example, a wire made of stainless steel, a plastic wire made of polyester resin, or the like is used. As the wire, various wire rods called ropes and cables can be used. Instead of the wire, for example, a steel tension material such as a tension reinforcing bar used in a reinforced concrete building, or another long metal tension material can be used.

The front and rear gable side wall frames 3F and 3B, and the left and right flat side wall surface frames 4L and 4R on which the wires 11 to 14 are stretched are the front and rear gable side anchor wires 15 (only the front side wire 15 is shown in the figure). ), And the flat anchor wires 17 and 18 on both sides are pulled outward in the front-rear direction and outside in the left-right direction, respectively. The flat-side anchor wires 17 project diagonally to the left and right outside of the greenhouse building 1. The flat side anchor wire 18 is vertically stretched inside the greenhouse building 1. These wires 15, 17, and 18 are hooked on the anchor steel material 51 embedded in the ground G, which is the installation surface.

A wall surface translucent film 8a is attached to the gable side wall frame 3F, 3B, and the flat side wall frame 4L, 4R. A roof surface translucent film 8b is attached to the roof surface 6. These translucent films are translucent films made of, for example, polyolefin resins. A skylight 9 for ventilation is formed at the peak portion of the roof surface 6 so as to extend in the front-rear direction with a constant width. The skylight 9 can be opened by winding up the skylight opening / closing film 10 that covers the skylight 9. The skylight opening / closing film 10 is a translucent film made of a polyolefin resin or the like. An insect repellent net (not shown) is stretched under the skylight opening / closing film 10 so as to cover the skylight 9.

A valley portion extending in the front-rear direction is formed between the roof surfaces 6 of the adjacent greenhouse buildings 2. In these valley portions, rain gutters 20 extending in the front-rear direction along the valley portions are formed. The rain gutter 20 has a predetermined water gradient from the center in the front-rear direction to the front-back direction.

Further, in the greenhouse building 2 of this example, an eave is attached to a portion on the upper end side of the outer wall surface of the four circumferences thereof. In FIG. 1, the eaves portion of the greenhouse building 2 (3) is shaded. The gable-side eaves 130 provided on the front and rear gable-side outer wall surfaces have long rigid body members such as film stoppers 131 and 132 bridged over the upper end side of the gable-side anchor wire 15. It is constructed by stretching a translucent film 133 having a constant width. Similarly, in the flat-side eaves 140 provided on the left and right flat-side outer wall surfaces, film stoppers 141 and 142 are bridged over the upper end side portion of the flat-side anchor wire 17, and a certain width of light is transmitted on the film stoppers 141 and 142. It is constructed by stretching a sex film 143. The structures of the eaves 130 and 140 will be described later (see FIG. 4).

[Mounting part of roof translucent film]
FIG. 2A shows a wire fixing portion of the roof surface 6 where the roof surface translucent film 8b is attached and a portion where the wire 11 and the film stopper to which the roof surface translucent film 8b is attached are connected and fixed. It is explanatory drawing which shows the structure.

Explaining with reference to FIGS. 1 and 2 (a), the mounting portion of the roof surface translucent film 8b connects and fixes the film stoppers 81 and 82 and the intersecting portion 83 of the film stoppers 81 and 82. It is composed of a connecting metal fitting 86 and a wedge metal fitting 87. The film stoppers 81 and 82 are common parts. On the upper side of the wires 11 arranged at regular intervals, film stoppers 82 arranged at regular intervals are connected and fixed in the orthogonal direction. On the upper side of the film stopper 82 which is connected and fixed to the wire 11, the film stopper 81 which is arranged at regular intervals in the orthogonal direction is connected and fixed. A roof surface translucent film 8b is attached to the film stopper 81.

The film stopper 81 is, for example, a metal member, and is arranged along a wire 12 stretched horizontally in the front-rear direction of the building. The film stopper 81 is a member having a groove-shaped cross section including a bottom plate portion 81a and side plate portions 81b formed on the left and right sides thereof. The left and right side plate portions 81b are inclined so that the tip sides approach each other, and a film stop groove 81c having a trapezoidal cross section is formed between them. The groove opening of the film stop groove 81c is narrower than the bottom surface of the groove. The film stoppers 81 are arranged so that the groove openings face downward, and the wire 12 passes through the film stoppers 81c.

On the upper side of the film stopper 81, the film stoppers 82 are arranged at regular intervals in the directions orthogonal to each other with a slope along the roof surface 6. The film stopper 82 is a component common to the lower film stopper 81, and includes a bottom plate portion 82a, left and right side plate portions 82b, and a film stopper groove 82c. The roof surface translucent film 8b is arranged so as to cover the upper side of the film stopper 82. A part of the roof surface translucent film 8b is inserted from above into the film retaining groove 82c of the film retaining material 82. The film portion inserted into the film stop groove 82c is fixed in the groove by the spring material 89 which is bent into a corrugated shape.

The intersecting portion 83 of the film stoppers 81 and 82 stacked vertically in an orthogonal state is connected and fixed by the connecting metal fitting 86 and the wedge metal fitting 87. The connecting metal fitting 86 is a metal fitting having a U-shaped cross section including a bottom plate portion 86a and side plate portions 86b formed on both sides thereof. Each of the side plate portions 86b is formed with a rectangular opening 86c that opens on the tip end side thereof. Engagement claws 86d protruding in the direction of approaching each other are formed on the inner edge portions on both sides of the rectangular opening 86c on the distal end side.

The wedge metal fitting 87 is a metal fitting having a U-shaped cross section including a rectangular bottom plate portion 87a and side plate portions 87b formed on both sides thereof, and an end plate portion 87c is formed at the rear end of the bottom plate portion 87a. The left and right side plate portions 87b have a wedge shape, and the height dimension thereof gradually decreases from the rear end on the side of the end plate portion 87c toward the tip on the opposite side. For example, the upper end surface of the side plate portion 87b is an inclined surface inclined toward the bottom side toward the tip end side.

A film stopper 81 and a wedge metal fitting 87 can be passed between the left and right side plate portions 86b of the connecting metal fitting 86. The film stopper 82 can be passed through the left and right rectangular openings 86c formed in the side plate portion 86b. Further, the left and right engaging claws 86d can be engaged with the left and right side plate portions 82b of the film stopper 82.

At the intersection 83 of the film stoppers 81 and 82, the connecting metal fitting 86 is attached from the lower side of the film stopper 81. The film stopper 81 passes between the left and right side plate portions 86b of the connecting metal fitting 86, and the upper film stopper 82 passes through the rectangular opening 86c of the left and right side plate portions 86b. In this state, the wedge metal fitting 87 is inserted between the bottom plate portion 86a of the connecting metal fitting 86 and the lower film stopper 81 from the tip side thereof. The end plate portion 87c, which is the driving surface of the wedge metal fitting 87, is hit to drive the wedge metal fitting 87. The front and rear engaging claws 86d formed on the left and right side plate portions 86b of the connecting metal fitting 86 are hooked from the upper side to the left and right side plate portions 82b of the upper film stopper 82. By adjusting the driving amount of the wedge metal fitting 87, the intersecting portion 83 of the orthogonal film stoppers 81 and 82 is securely connected and fixed by the connecting metal fitting 86.

[Wire fixing structure]
Next, with reference to FIGS. 2A to 2C, a wire fixing structure for connecting and fixing the intersecting portion 90 between the wire 11 and the film stopper 81 on the roof surface 6 will be described. The wire fixing structure is a wedge-type fixing structure, and is composed of a wire connecting metal fitting 91 for connecting and fixing the intersecting portion 90 and a wedge metal fitting 92. FIG. 2B is a perspective view showing the wire connecting metal fitting 91 and the wedge metal fitting 92 separated from each other, and FIG. 2C is a side view of the wedge metal fitting 92.

The wire connecting metal fitting 91 is a component common to the connecting metal fitting 86 used for connecting and fixing the intersecting portion 83 of the film stoppers 81 and 82. As shown in FIG. 2B, the wire connecting metal fitting 91 is a metal fitting having a U-shaped cross section including a bottom plate portion 91a and side plate portions 91b formed on both sides thereof. Each of the side plate portions 91b is formed with a rectangular opening 91c that opens on the tip end side thereof. Engagement claws 91d protruding in the direction of approaching each other are formed on the inner edge portions on both sides of the rectangular opening 91c on the distal end side. It is also possible to manufacture the wire connecting metal fitting 91 as a part having a shape and dimensions different from that of the connecting metal fitting 86.

Next, as shown in FIGS. 2B and 2C, the wedge metal fitting 92 has a rectangular bottom plate portion 92a, side plate portions 92b formed on both sides thereof, and an end plate formed at the rear end of the bottom plate portion 92a. A U-shaped cross-section metal fitting with a portion 92c. The left and right side plate portions 92b have a wedge shape, and the height dimension thereof gradually decreases from the rear end on the side of the end plate portion 92c toward the tip on the opposite side. In this example, the upper end surface of the side plate portion 92b is an inclined surface inclined to the bottom side toward the tip end side. The basic configuration of the wedge metal fitting 92 is the same as that of the wedge metal fitting 87 described above, but the height dimension of the left and right side plate portions 92b is larger than that of the side plate portion 87b of the wedge metal fitting 87. Further, in the wedge metal fitting 92, a wire through groove 92d extending linearly in the front-rear direction is formed at the center of the bottom plate portion 92a in the width direction. The wire through groove 92d is a groove having a substantially arcuate cross section that opens downward in the central portion of the back surface of the bottom plate portion 92a.

In the wire connecting metal fitting 91, as shown in FIG. 2A, it is possible to pass the wedge metal fitting 92 between the left and right side plate portions 91b. The film stopper 81 can be passed through the left and right rectangular openings 91c formed in the left and right side plate portions 91b. Further, the left and right engaging claws 91d can be engaged with the left and right side plate portions 81b of the film stopper 81.

At the intersection 90 of the wire 11 and the film stopper 81, the wire connecting metal fitting 91 is attached from above the wire 11. The lower film stopper 81 is passed through the rectangular opening 91c of the left and right side plate portions 91b of the wire connecting metal fitting 91. In this state, the wire through groove 92d of the wedge metal fitting 92 is positioned on the wire 11. The wedge metal fitting 92 is inserted along the wire 11 from the tip end side between the bottom plate portion 91a of the wire connecting metal fitting 91 and the bottom plate portion 81a of the lower film stopper 81. The end plate portion 92c, which is the driving surface of the wedge metal fitting 92, is hit to drive the wedge metal fitting 92. The front and rear engaging claws 91d formed on the left and right side plate portions 91b of the wire connecting metal fitting 91 are pressed from the lower side against the left and right side plate portions 81b of the lower film stopper 81. By adjusting the driving amount of the wedge metal fitting 92, the intersecting portion 83 of the wire 11 and the film stopper 81 is securely connected and fixed by the wire connecting metal fitting 91.

Conventionally, holes such as screws and bolts are formed in the member to be connected or the connecting metal fitting, and the connecting metal fitting is fixed to the member to be connected by using screws and bolts. In this case, the screws and the like are often loosened due to vibration and the like generated by wind and the like, and it is difficult to secure weather resistance. In this example, by using the wedge mechanism, the members to be connected can be easily connected and fixed, and the connecting portion is less likely to loosen.

Further, in the wedge metal fitting 92 of this example, a wire through groove 92d having an arcuate cross section having a predetermined length is formed. The wire 11 is pressed by the curved inner peripheral surface of the wire through groove 92d. Since the contact area for pressing the wire 11 can be increased, the wire can be securely fixed without being damaged.

Next, the wedge metal fitting 92 of this example can be used upside down. FIG. 2D is an explanatory view showing a wire fixing structure when the wedge metal fitting 92 is driven in the opposite direction. In this case, the wire 11 is passed between the bottom plate portion 91a of the wire connecting metal fitting 91 and the bottom plate portion 92a of the wedge metal fitting 92, and is fixed between them. Both can be connected and fixed with a gap provided between the film stopper 81 and the wire 11.

For example, when the roof surface translucent film 8b is stretched under the film stopper 81, a predetermined gap can be formed between the translucent film 8b and the wire 11. The roof surface translucent film 8b may bend in the vertical direction due to wind or the like and hit the wire 11 to be damaged. When there is such a risk, it is desirable to connect and fix the wire 11 and the film stopper 81 at a predetermined interval. In the wire fixing structure of this example, the wire 11 and the film stopper 81 can be switched between a state without a gap and a state with a gap only by changing the direction of the wedge metal fitting 92.

[Another example of wire fixing structure]
3 (a) and 3 (b) are perspective views and plan views showing another example of the wire fixing structure, and FIGS. 3 (c) and 3 (d) are perspective views and a plan view showing still another example of the wire fixing structure. It is a plan view. In these wire fixing structures, the wedge fitting presses the wire against the film stopper plate via a shim plate (wire retainer).

The wire fixing structure shown in FIGS. 3A and 3B is composed of a wire connecting metal fitting 101, a wedge metal fitting 102, and a shim plate 103. As shown in FIG. 3A, the wire connecting metal fitting 101 includes left and right side plate portions 101b and front and rear bottom plate portions 101a connecting the lower ends of these side plate portions 101b. There is an opening between the front and rear bottom plate portions 101a. Further, rectangular openings 101c that open downward are formed in the left and right side plate portions 101b. Engagement claws 101d protruding in the direction of approaching each other are formed on the front and rear inner edge portions of the lower end of the rectangular opening 101c.

The wedge metal fitting 102 is a metal fitting having a U-shaped cross section including a rectangular bottom plate portion 102a and side plate portions 102b formed on both sides thereof. The left and right side plate portions 102b have a wedge shape, and the height dimension thereof gradually decreases from the rear end in the length direction toward the tip.

The shim plate 103 is an elongated rectangular plate, and a wire through groove 103a extending linearly in the front-rear direction is formed in a central portion in the width direction. The wire through groove 103a is a groove having a substantially arcuate cross section that opens downward in the central portion of the back surface of the shim plate 103.

In the wire connecting metal fitting 101, the film stopper 81 can be passed through the rectangular openings 10c formed in the left and right side plate portions 101b. Further, the front and rear engaging claws 101d can be engaged with the left and right side plate portions 81b of the film stopper 81. The shim plate 103 can be passed between the left and right side plate portions 101b of the wire connecting metal fitting 101.

At the intersection of the wire 11 and the film stopper 81, the wire connecting metal fitting 101 is attached from above the wire 11. The lower film stopper 81 is passed through the rectangular opening 101c of the left and right side plate portions 101b of the wire connecting metal fitting 101. In this state, the wire through groove 103a of the shim plate 103 is positioned on the wire 11. The shim plate 103 is placed on the bottom surface of the film stopper 81 with the wire 11 sandwiched between the left and right side plate portions 101b. In this state, the wedge metal fitting 102 is inserted into the rectangular opening 102c of the left and right side plate portions 102b of the wire connecting metal fitting 101. That is, the wedge metal fitting 102 is inserted from the tip end side between the inner peripheral edge of the upper end of the rectangular opening 102c and the shim plate 103. Then, the wedge metal fitting 102 is driven in.

The intersection of the wire 11 and the film stopper 81 is securely connected and fixed by the wedge effect of the wedge metal fitting 112 and the spring force of the leaf spring portion 112c. Also in this case, the shim plate 113 is used to secure the contact area and the contact length with the wire 11. Since the wedge metal fitting 112 does not come into direct contact with the wire 11, the shape of the wedge metal fitting 112 can be set more freely.

In each of the above examples, the wire fixing structure for fixing the intersecting portion between the wire and the film stopper has been described. The wire fixing structure of the present invention can be used to connect and fix a long rigid body member other than a film stopper and a wire. For example, it can be applied to connect and fix a pipe having a cylindrical cross section or a rectangular cross section and a tension wire.

[Example of anchor wire]
An example of an anchor wire suitable for use as a flat side anchor wire 17 and 18 and a gable side anchor wire 15 will be described with reference to FIG. The flat side anchor wire will be described below, but the gable side anchor wire can also have the same structure. FIG. 4A is a schematic side view showing the flat side anchor wire, and FIG. 4B is an explanatory view showing the upper wire thereof.

The flat side anchor wire 170 is composed of an upper wire 171 and a lower drawer wire 172, and a turnbuckle 173 bridged between them. The upper wire 171 is a wire made of stainless steel, and has a wire body 171a having a predetermined length, loop portions 171b and 171c formed at both ends thereof, and a metal cylindrical clip 171d for crimping covering the wire ends. It is equipped with 171e. The upper loop portion 171b is hooked on the upper end portion of the flat side wall surface frame 4L, for example, the flat side horizontal member 34, and the lower loop portion 171c is hooked on the upper hook 173a of the turnbuckle 173.

The lower drawer wire 172 is a wire made of stainless steel, and includes a wire body 172a having a predetermined length, loop portions 172b and 172c formed at both ends thereof, and metal cylindrical clips 172d and 172e for crimping. There is. The upper loop portion 172b is hooked on the lower hook 173b of the turnbuckle 173. The lower loop portion 172c is hooked on the anchor steel material 53 buried in the ground.

In the upper loop portion 172b of the lower pull-out wire 172, the wire end 172f is pulled out from the cylindrical clip 172d by a predetermined length. The wire portion 172g from the cylindrical clip 172d to the wire end 172f in the lower drawer wire 172 functions as a wire length adjusting portion. When the wire portion 172g is pushed toward the cylindrical clip 172d, the loop length 172h of the loop portion 172c becomes longer, and the bridging length of the lower drawer wire 172 can be lengthened. After adjusting to an appropriate bridging length, the cylindrical clip 172d is crimped.

The lower drawer wire 172 is pulled out to the ground from the anchor steel material 53 buried in the ground. The underground portion of the lower drawer wire 172 is protected by passing it through a protective pipe 175 such as a vinyl chloride pipe. The upper loop portion 171b of the upper wire 171 is hooked on the upper end portion of the flat side wall surface frame 4L, and the lower loop portion 171c and the upper loop portion 172b of the lower drawer wire 172 pulled out from the ground In the meantime, a turnbuckle 173 is hung. Turn the turnbuckle 173 to bring the flat anchor wire 170 into a predetermined tension state. As shown by the imaginary line, the flat side anchor wire 170 can be covered with a protective tube 176 such as a vinyl chloride tube.

There are variations in the length of the flat side anchor wire 170 installed at the site. By adjusting the loop length 172h of the upper loop portion 172b of the lower drawer wire 172, the bridging length of the flat side anchor wire 170 can be set to an appropriate length. Therefore, the turnbuckle 173 can provide the required tensile force to the flat anchor wire 170. A tension adjusting member other than the turnbuckle, for example, a latch type wire winding mechanism can be used.

[Eave structure]
