[Problems to be solved by the device]

 By the way, there are two types of roofing materials, corrugated sheet and flat sheet, and the flat sheet is usually a transparent acrylic sheet. The corrugated sheet and the flat plate differ in the fixing method.The corrugated sheet is placed on the main purlin bridge 51 and the middle purlin is passed over, and the middle purlin is hooked and locked. It is placed directly on the upper surface of the, and the holding plate is put on the flat plate, and nails are driven in to fix it. In the case of the former, it is necessary to fix the purlin bridge 51 at a higher position because there must be a gap between the purlin bridge 51 and the roofing material (corrugated sheet) to insert the middle purlin. In the latter case, it is not necessary to provide a gap between the purlin bridge 51 and the roof material (flat plate).

As described above, since the mounting position of the purlin support differs depending on the roof material used, it is not possible to share the parts, and the purlin support and the mounting girder material of different shapes for the corrugated plate and the flat plate, I was preparing a gutter. However, such an increase in the number of parts increases the manufacturing cost and is not preferable. The present invention has been made in view of such circumstances, and an object thereof is to provide a roof support structure for a terrace that can reduce manufacturing costs.

[0005]

[Means for Solving the Problems]

 The terrace roof support structure of the present invention includes a terrace roof material, a plurality of purlin supports, and a horizontally long mounting girder member that is attached to the outer wall of the building to support the base ends of the roof and purlin supports. , A gutter that is inserted into the tip side of the roof material and is attached to the tip side of the purlin support, a first mounting bracket that is attached to the base end side of the purlin support and that supports the purlin support to the mounting girder material, and the purlin support. A roof supporting structure for a terrace, which is attached to the tip of the roof and comprises a second mounting bracket for supporting the gutter on the purlin support, wherein the mounting girder member includes a holding portion for holding the base end edge of the roof material, and (1) A fitting groove for movably supporting the mounting bracket in the longitudinal direction is provided, and the cross-sectional shape of the fitting groove is a long rectangular shape that is vertically long and surrounded by wall material on four sides, and has a purlin receiving side wall surface. A widthwise opening is formed in the longitudinal direction at approximately the center of the vertical direction. The gutter is provided with an insertion part for inserting the tip edge of the roofing material and a fitting groove for movably supporting the second mounting member in the longitudinal direction. The fitting groove has a cross-sectional shape of four walls. A widthwise opening is formed in the longitudinal direction at approximately the center in the vertical direction surrounded by the material. The first mounting bracket and the second mounting bracket pass through bolts at one end in the thickness direction at both longitudinal ends of the purlin bridge. It is characterized by being fixed to.

[0006]

[Action]

 In the present invention, if the sliding pieces of the first and second mounting brackets are inserted upward into the fitting girders and the fitting grooves of the gutter, the gap between the roof material and the purlin bridge is eliminated, and if the sliding pieces are inserted downward, the roof material and the mother board are closed.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. Figure 1 is a cross-sectional side view of the main part of a roof support structure for a terrace when corrugated sheet A is used as the roof material, and Figure 2 is a roof support structure for a terrace when a flat plate (transparent acrylic plate) B is used as the roof material. FIG. 3 is a cross-sectional side view of an essential part of FIG.

First, a support structure common to both roofing members A and B will be described with reference to FIGS. 1 and 3 to 6. In FIG. 1, 1 is a purlin bridge, 2 is a mounting girder material, 3 is a gutter, and 4 is a column. The purlin bridge 1 is a rectangular tubular member, and is a simple square bar that does not require the engaging groove 57 unlike the purlin bridge 51 (see FIG. 5) of the conventional example. The first mounting member 5 is attached to the tip side of the purlin support 51, and the second mounting member 6 is attached to the base end side. Both the first mounting member 5 and the second mounting member 6 are mounted on one end portion (upper end portion in FIG. 1) in the thickness direction at both end portions of the purlin bridge 1.

Since the first mounting member 5 and the second mounting member 6 have the same shape, the shape will be described by taking the first mounting member 5 as a representative. As shown in FIG. 3, it is provided with a rectangular block-shaped main body 10 and an L-shaped engaging body 11 protruding from the main body 10. The engaging body 11 is a connecting piece 12 connected to the main body 10 and a direction perpendicular to the tip thereof. And a sliding piece 13 extending to. A cavity 14 is formed inside the main body 10, and a female screw hole 15 for inserting a mounting bolt is formed therein. An L-shaped stopper plate 16 projects from the upper end of the main body 10, and a tongue piece 17 projects from the lower end of the main body 10. FIG. 4 shows a state in which the mounting bracket 5 (6) is fixed to the purlin bridge 1 through the bolt 18.

FIG. 5 is a sectional view of the mounting girder 2. The mounting girder 2 is a long member to be mounted on the outer wall C of the building, and has a holding portion 21 for holding the base end edge of the roof material and a fitting groove 22 for supporting the first mounting bracket 5. ing. The fitting groove 22 is in the shape of an elongated rectangle that is surrounded by wall material on four sides and is long in the vertical direction, and a narrow opening 24 is formed substantially in the vertical center of the purlin receiving side wall surface 23. The inner width of the fitting groove 22 is a width into which the sliding piece 13 of the fitting 5 (6) is inserted, and the inner dimension in the vertical direction is almost twice that of the sliding piece 13. Therefore, the connecting piece 12 of the mounting member 5 (6) can be inserted into the fitting groove 22 either through the opening 24 with the sliding piece 13 facing upward or downward.

FIG. 6 is a sectional view of the gutter 3. The trough 3 is provided with a fitting groove 32 into which the second fitting 6 is inserted on the back surface side. The fitting groove 32 has the same shape as the fitting groove 22 of the mounting girder 2, and a narrow opening 34 is formed at a substantially vertical center of the roof receiving side wall surface 33. In addition, it is provided with a U-shaped trough 35 in cross section for draining rainwater, the front side wall is bent at the upper end at the rear side to form an upper holding wall 36, and the rear side wall is at the upper end. The lower holding part 37 is formed flat and the upper holding part 36 and the lower holding wall 37 form an insertion part 38 for inserting and holding the roof material.

Next, a method of using the above embodiment will be described. FIG. 1 is an example of attachment when corrugated sheet A is used as the roof material. The corrugated plate A is inserted and held between the holding portion 21 of the mounting girder 2 and the insertion portion 38 of the gutter 3. The sliding pieces 13 of the first mounting member 5 and the second mounting member 6 are inserted downward in the fitting groove 22 of the mounting girder 2 and the fitting groove 32 of the gutter 3. In this case, the first mounting member 5 and the second mounting member 6 can be moved in the longitudinal direction along the fitting grooves 22 and 32. Then, the bolt 18 is screwed and fixed at a position matching the purlin bridge 1. At this time, since the main body of each mounting member 5 (6) is supported by the tongue piece 17, the bolt 18 can be easily screwed in without tilting. Then, screws 19 are screwed into the stopper plate 16 to fix the purlin support 1 to the mounting girder 2 and the gutter 3 to the purlin support 1.

In the case of the mounting example shown in FIG. 1, since there is a space between the purlin bridge 1 and the corrugated sheet A, the middle purlin 7 can be transferred onto the plural purlin bridges 1. Then, the corrugated sheet A can be fixed by the hook hooked on the middle purlin 7.

FIG. 2 shows an example of attachment when the flat plate B is used as the roof material. A flat plate B of a transparent acrylic plate and its holding plate D are inserted into the holding part 21 of the mounting girder 2 and the insertion part 38 of the gutter 3, and the sliding pieces of the first mounting bracket 5 and the second mounting bracket 6 respectively. 13 is inserted upward in the fitting groove 22 of the mounting girder 2 and the fitting groove 32 of the gutter 3. In this case, since there is no gap between the flat plate B which is the roof material and the upper surface of the purlin bridge 1, the flat plate B can be directly fixed to the purlin bridge 1 with a nail or the like.

As described above, in this embodiment, since all members except the roofing material can be shared, the manufacturing cost can be reduced and the number of terrace assembling steps can be reduced.
