Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a roof base for pasting roof coverings such as light-shielding curtains and thick synthetic resin films, or roofing sheets having elasticity, and is applicable to temporary houses, It is suitable for the palm-shaped roofs of simple warehouses, greenhouses, etc.

``Prior art'' Conventionally, in temporary houses and greenhouses with gassho roofs, for example, the base material for pasting corrugated or flat roof sheets made of synthetic resin is to lay base materials of the same height on the slopes of the gassho materials. Because the roof panels are fixed at intervals of The head of the roof protruded from the surface of the roof shingles, which had the disadvantage of making it harder for snow to slide on the roof surface. In addition, when a roofing is placed on the roof base instead of the above-mentioned roof sheets, rafter members are fixed to the main building material at predetermined intervals, and both hems of the roofing are tied to the eaves by means of strings, etc. In order to secure the roof and prevent the roof from blowing due to the wind, ropes were used to hold the roof between the rafters. It had drawbacks such as making it worse.

``Problems to be Solved by the Invention'' When installing elastic roof plates, there is no need to screw the roof plates to the main building material at the center of the slope of the roof.
To provide a roof base which allows the work of applying roof sheets to be carried out quickly and which allows snow on the roof to slide more easily. In addition, when installing a roof, there is no need to hold down the roof with a rope, so the work of installing the roof can be done more quickly, and a roof base is provided that does not prevent snow from sliding on the roof. It is to be.

``Means for Solving the Problems'' The first invention is a roof base in the shape of a roof in which three or more purlins are arranged at predetermined intervals on the upper part of the gassho materials on both slopes, from the slopes of the gassho materials. The height of each purlin material is set so that the line connecting the upper ends of each purlin material forms a polygonal arc when viewed from the slope of the gassho material, and It is attached to the gassho material so as to be movable in the direction of inclination, and another purlin material is fixed to the gassho material, so that the purlin material of the eaves can be pulled downward in the direction of inclination of the gassho material.

Further, a second invention provides an arc-shaped rafter along the polygonal arc in a state of intersecting with other purlin materials other than the uppermost purlin material such as the eave part purlin material among the purlin materials of the first invention. This is because the shaped members are attached at predetermined intervals.

``Function'' When the roof base is structured as described above, when installing elastic roofing sheets or roofing, one end of the roofing sheet or roofing can be attached to the top of the ridge or to the main building at the position closest to the top of the ridge. It can be fixed to the material with screws, etc., and the other end of the roof board or roofing can be similarly fixed to the eave purlin material, and the eave purlin material can be stretched downward in the direction of the slope of the gassho materials. . In addition, in houses where the roof has a relatively narrow span (gable width) from eave to eave, both ends of the roof can be fixed to the purlins of both eaves.
The purlin materials of both eaves parts can be drawn and stretched downward in the direction of inclination of the gassho materials.

The height of each purlin material from the slope of the gassho material is set so that the line connecting the upper ends of each purlin material forms a polygonal arc when viewed from the slope of the gassho material. By pulling the purlin material downward and tensioning it, the roof shingles are tensioned in an arc shape along the polygonal arc, so that there is no slack.
It is firmly attached to each purlin or rafter-like member.

"Embodiment" FIGS. 1 and 3 to 5 show an embodiment of the first invention.

1 are gassho members made of Z-shaped steel, which are provided at regular intervals in the direction of the ridge and supported by pillars 2 on the sides.

Purlin materials 31~ arranged at predetermined intervals on the upper surface of the gassho material 1
35, the purlin material 31 of the eave part (the lowest part in the inclination direction of the gassho material l) is provided in a movable state in the inclination direction of the gassho material l, and the other purlin materials 32, 33, 34, and 35 are It is fixed to the material 1 by suitable means.

The height h of each purlin material 31 to 35 from the slope of the gassho material 1 is such that the line connecting the upper ends of each of the purlin materials 31 to 35 forms a polygonal arc when viewed from the slope of the gassho material 1. is set to
Therefore, in this embodiment, the height h of the central purlin material 33 on one slope is the highest, the height h of the purlin materials 32 and 34 adjacent to the purlin material 33 is the next highest, and the height h of the purlin material 33 at the top of the ridge is the second highest. 35 and the height h of the eave purlin material 31 are the lowest. Because of this configuration, in this embodiment, the main building material 3
2 to 34 are not fixed directly to the gassho material 1, but are attached to the supporting pieces 1, respectively.
It is fixed via 1.

The eaves main building material 31 is constructed so that it can be pulled to a support member 5 provided on the upper side of the house using ports 4 and nuts 41, as shown in FIG. Porto 4. Instead of this, a turnbuckle (not shown) may be used for the nut 41, or the nut 41 may be configured to be pulled by a spring (not shown).

In addition, the main building material 31 of the eaves part is made of gassho material 1 by appropriate means.
It may be provided so that it is movable only in the direction of inclination.

A roof board 6 having a cap-shaped cross section is fixed to opposing surfaces of the purlin members 35 and 35 at a position near the top of the ridge via long support members Ell, 81. This roof plate 6 may be constructed so that it can be opened and closed in the vertical direction together with the support members 81 and 131.

To attach an elastic corrugated roof plate to the roof base of the structure described above, one end of the roof plate 7 cut to match the width of the sloped surface of the roof is screwed to the uppermost purlin material 35. The other end of the roof board 7 is fixed to the eave purlin material 31, and the port 4. is fixed as shown in FIG. It is sufficient to tighten the oak 1-41 to tension the purlin material 31 toward the hem of the roof. In this embodiment, in order to prevent a gap from occurring between the roof board 7 and the purlin material 31, the purlin material 31 has a main body 3a that is in sliding contact with the purlin material 1 and an upper surface as shown in FIGS. 4 and 5. The main body 3a has a bearing surface that substantially matches the waveform of the roof plate 7.
The roof board 7 is fixed to the main building material 31 by a port nut 71 via a holding plate 72 having a lip-hat shape in cross section.

The roof base of the above embodiment is made of gassho materials l of the main building materials 31 to 35.
The height h from the slope of Since it is configured to be able to be pulled downward, when installing the roof board 7, there is no need to fix the roof board 7 to the purlins 32 to 34 in the middle of the sloped surface of the roof with screws, and the roof board 7 is easier to put on, and it also makes it easier to slide on snow.

FIG. 2 shows an embodiment of the second invention, in which a roof base is constructed in substantially the same manner as the embodiment of the first invention, except for the purlin material 31 of the eaves and the purlin material 35 of the ridge top. The purlin materials 32 to 34 are placed in a state perpendicular to the purlin materials 32 to 34.
Pipe-shaped rafter-like members 8 bent into an arc along a polygonal arc formed by lines connecting the upper ends of the pipes 34 are fixed at regular intervals by appropriate means. The rafter-like member 8 is
It is desirable to bend both ends downwards as shown in the figure.
This rafter-like member 8 is provided to reinforce the roof base when the slope of the roof is wide, and is particularly effective in preventing the curtain from being blown away by the wind when the roof curtain is rolled.

For example, when applying a roof curtain to the roof base of the above embodiment,
Overlap the ends of the roof curtains 9, 9 from both slopes of the roof on the purlin material 35.35 at the top of the ridge, and fix the ends to each purlin material 35 with screws or the like while holding the end portions with the presser plates 91. Then, the hem side end of each roof curtain 9 is attached to the eave purlin material 31.
Similarly to the embodiment of the first invention, the eaves purlin 31 can be pulled downward in the direction of inclination of the gassho agent 1 by tensioning it.

In addition, in a house where the width from eave part to eave part (gable width) of the roof is relatively narrow, both ends of the roof curtain 9 are fixed to the purlin materials 31 of both eaves parts, and It is sufficient to pull the material 31 downward in the direction of inclination of the gassho material 1 and tension it.

In the embodiment described above, there is no need to hold down the roof curtain 8 with a rope, so the work is not time-consuming and does not prevent snow from sliding.

The procedure for applying roof curtains to the roof base in the above-mentioned invention is in accordance with the detailed explanation of the second invention, and the procedure for applying roof sheets to the roof base in the second invention is the same as the detailed explanation of the first invention. However, in the case where elastic corrugated roof plates are applied to the roof base according to the second invention, the rafter-like members 8 are pipe-shaped as shown in FIG. It is desirable to fit it into the corrugated part of the roof shingle.

"Effects of the Invention J The R-root base structure according to the present invention is applicable to the sloped surface of the gassho materials in a gassho-shaped roof foundation in which three or more purlin materials are arranged at predetermined intervals on the top of the gassho materials on both slopes. The height h of each purlin material from It is attached to the gassho material so as to be movable in the direction of inclination, and at the same time, other purlin materials are fixed to the gassho material.

The light and thin main building material is configured to be able to be pulled downward in the direction of inclination of the gassho material, and when installing elastic roof panels, it is sufficient to screw only both ends of the roof panels to the base. Therefore, the roof shingle work can be carried out efficiently, and the roof shingles can be installed in a state where the sliding of snow is better.

Furthermore, since there is no need to hold down the roof curtain with a rope when putting up the roof curtain, the roof curtain can be put up efficiently and in a state where the snow can slide better.

Furthermore, the second invention is one in which arc-shaped rafter-like members are attached at predetermined intervals to intersect with other purlin materials of the first invention, excluding the light and thin purlin material and the uppermost purlin material. In addition to exhibiting the above-mentioned effects, a reinforced base is constructed,
In addition, when a roof curtain or the like is put up, it is difficult for wind to blow the roof.
