Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connecting structure of girders and barrels that form a roof of a simple building such as a garage or a terrace.

[0002]

[Prior Art]

 As a connecting structure of girders and rafters constituting the roof of a simple building, for example, the one disclosed in Japanese Utility Model Laid-Open No. 63-143603 is known. That is, as shown in FIG. 1, the horizontal piece 2a of the connecting member 2 is connected to the upper portion of the girder 1 with the screw 3, the hollow barrel 4 is fitted to the vertical piece 2b of the connecting member 2, and the barrel 4 is connected. The material 2 is connected with the bolt 5 to connect the girder 1 and the rafter 4.

[0003]

[Problems to be solved by the device]

 With such a connecting structure, the lower end surface 4a of the rafter 4 is in contact with the upper surface of the horizontal piece 2a of the connecting member 2, and the outer vertical surface 4b of the rafter 4 is slightly inward of the outer vertical surface 1a of the rafter 1. Therefore, rainwater flowing along the outer vertical surface 4b of the rafter 4 invades inward by the contact portion between the horizontal piece 2a of the connecting member 2 and the lower end surface 4a of the rafter 4 and is provided on the outer vertical surface 4b of the girder 1. The water does not flow down smoothly into the rain gutter portion 6 and the drainage performance deteriorates. Moreover, a gap is formed between the upper surface 1b of the girder 1 and the lower end surface 4a of the rafter 4 and the appearance becomes poor.

Therefore, an object of the present invention is to provide a roof girder-barrel connecting structure that can solve the above problems.

[0005]

[Means for Solving the Problems]

 A vertical piece for connecting a tree, which is an outer portion of the upper plate 11 of the girder 10, is provided continuously with the outer vertical plate 14, and the inner vertical plate 21, the outer vertical plate 22 and the both side vertical plates 23, 23 have a hollow shape, and the outer vertical plate thereof. A board 22 having a drainage recessed portion 26 in a plate 22 is used, and this bark 20 is used as a girder 10 and an inner side surface 22a of an outer vertical plate 22 thereof contacts an outer surface of a vertical piece for connecting a tree, and a lower end surface 20a of the girder 10 is provided. A roof girder-barrel connection structure in which the outer bar 22 of the rafter 20 is attached to the upper plate 11 and the outer vertical plate 22 of the rafter 20 is fixed to the rafter-connecting vertical piece with a screw 45 to connect the rafter to the girder 10.

[0006]

[Work]

 The outer vertical plate 22 of the rafter 20 is located outside the outer vertical plate 14 of the girder 10, and the lower end surface 20a of the rafter 20 is in contact with the upper plate 11 of the girder 10. Therefore, the drainage recess of the outer vertical plate 22 of the rafter 10 is provided. The rainwater that has flowed down along 26 does not flow to the contact portion between the upper plate 11 of the girder 10 and the lower end surface 20a of the rafter 20, and the rainwater smoothly flows into the gutter part of the girder 10 to improve drainage. However, there is no gap between the upper plate 11 of the girder 10 and the lower end surface 20a of the rafter 20 and the appearance is good.

【Example】

 As shown in FIG. 2 and FIG. 3, a plurality of trees 20 on the upper surface of the girder 10 are connected at intervals in the longitudinal direction, and a roofing material 30 is attached between the adjacent trees 20 to form a roof of a simple building. ing. The girder 10 has a hollow shape including an upper plate 11, a lower plate 12, an inner vertical plate 13, and an outer vertical plate 14, and the upper plate 11 is inclined with respect to the horizontal so that the outside is higher and the inside is lower, and the lower 12 Is horizontal and the inner vertical plate 13 is vertical, and the outer vertical piece 14 has a V shape with a vertical lower portion 14a and an upper portion 14b inclined with respect to the vertical. The horizontal plate 15 is integrally provided, and the vertical plate 16 having a substantially circular arc shape is integrally provided over the lower end portion of the horizontal plate 15 and the outer vertical piece 14 to form an upwardly concave rain gutter part 17. The projecting piece 18 is integrally provided on the inner end of the upper plate 11 continuously in the longitudinal direction, and the L-shaped piece 19 is integrally provided on the upper part 14b of the outer vertical plate 14 in the longitudinal direction. A concave groove 19a is formed in the L-shaped piece 19.

As shown in FIG. 3, the rafter 20 has an inner vertical plate 21 facing each other, an outer vertical plate 22 and both vertical plates 23, 23 facing each other, and has a hollow rectangular cross section. Groove portions 24 are formed at both end portions of the groove, and a U-shaped protruding portion 25 is formed at an intermediate portion in both sides, and a drainage recess 26 is formed between the U-shaped protruding portion 25 and the groove groove 24. Are configured respectively.

As shown in FIG. 3, the left and right sides of the roof material 30 are attached to the airtight material 31 attached to the groove groove 24 of the rafter 20 and the ridge 32 screwed to the U-shaped protrusion 25 of the rafter 20. As shown in FIG. 2, the lower part of the roofing material 30 is held by the airtight material 33, and the upper edge of the holding plate 35 screwed to the airtight material 34 mounted on the groove 19a of the L-shaped piece 19 and the horizontal plate 15 is held. It is held by an airtight material 36 attached to the groove 35a and protrudes into the rain gutter portion 17.

A connecting member 40 is screwed to the upper plate 11 of the girder 10. The connecting member 40 includes a horizontal piece 41 and a vertical piece 42, which is a vertical piece for connecting trees, and is substantially L-shaped. A fin piece 43 is integrally provided below the horizontal piece 42 at the lower part of the horizontal piece 42. The fin piece 43 is positioned in contact with the upper end of the outer vertical plate 14 to position the horizontal piece 41 on the upper plate 11. The outer surface 42a of the vertical piece 42 projects outward from the outer vertical plate 14 of the girder 10. In the rafter 20, the inner side surface 22a of the outer vertical plate 22 is in contact with the outer side surface 42a of the vertical piece 42 of the connecting member 40, the outer side surface 21a of the inner vertical plate 21 is in contact with the protruding piece 18 of the girder 10, and the lower end surface 20a is Positioned in contact with the upper plate 11 of the girder 10, the screw 45 is screwed into the vertical piece 42 of the connecting member 40 from the drainage recess 26 of the outer vertical plate 22 of the rafter 20 to connect the rafter 20 to the girder 10. . The screw 45 may be screwed onto the vertical piece 42 of the connecting member 40 from a portion other than the drainage recess 26 of the outer vertical plate 22.

Because of this, the rainwater that has flowed along the drainage recess 26 of the tree 20, which is the outer vertical plate 22 of the rafter 20 outside the outer vertical plate 14 of the girder 10, can smoothly flow to the outer vertical plate. Since it flows into the rain gutter part 22 and flows down into the rain gutter part 17, drainage performance improves. Since the lower end surface 20a of the rafter 20 is in contact with the upper plate 11 of the girder 10, there is no gap and the appearance is good.
