[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention relates to a joint structure between a horizontal frame and an inclined frame such as a climbing beam in a roof frame, and can be used for a roof unit or the like.

[0002]

[Background technology]

 For example, in a prefabricated unit building constructed by a plurality of building units, a roof unit is also used for the roof, and a gable roof or the like is assembled by combining a plurality of roof units on site. As shown in FIGS. 3 and 4, a roof frame 31 of such a roof unit is configured to include a horizontal frame such as a floor frame 32, an inclined frame 33, a bundle and the like.

In the floor frame 32, beams 34 are assembled in a rectangular shape, and small beams are bridged between the beams 34 facing each other. The inclined frame 33 is assembled by a plurality of climbing beams 35 and the like, and a roof panel, which is a roof material, is mounted on the inclined frame 33.

As shown in the figure, the joint between the inclined frame 33 and the floor frame 32 in the roof frame 31 is performed via a bracket 36. The bracket 36 is joined to a base portion 37 fixed to the outer surface of the beam 34 of the floor frame 32, a receiving portion 38 of the inclined frame 33 formed obliquely upward from the upper end portion of the base portion 37, and both 37, 38. It is configured to have a reinforcing material 39.

[0005]

[Problems to be solved by the device]

 In the above-mentioned conventional joint structure of the inclined frame 33 and the floor frame 32 in the roof frame 31, the receiving portion 38 of the bracket 36 and the reinforcing member 39 are provided so as to protrude to the outside of the floor frame 32. In the case of such a joint structure, the receiving portion 38 and the reinforcing member 39 will protrude to the outside of the floor frame 32 regardless of how the lengths of the base portion 37 and the receiving portion 38 of the bracket 36 are adjusted.

Therefore, when an attempt is made to attach a part 43 such as an eaves tip unit to the side surface of the floor frame 32, such a bracket 36 has been an obstacle. Therefore, an object of the present invention is to provide a joint structure for a roof frame in which the bracket does not extend outside the horizontal frame.

[0007]

[Means for Solving the Problems]

 The joint structure of the roof frame according to the present invention uses a bracket having a base portion and a receiving portion, and while the bracket is positioned inside the horizontal frame, the base portion is fixed to the upper surface of the horizontal frame, and The end portion is fixed to the receiving portion. The horizontal frame is a floor frame, a ceiling frame, or the like, which is squarely assembled by beams. The tilted frame is a frame formed by climbing beams and the like.

[0008]

[Action]

 In this roof frame joint structure, a bracket located inside the horizontal frame was used, and the inclined frame was fixed via this bracket, so both the bracket and the inclined frame should not stick out of the horizontal frame. Disappears. Therefore, the bracket does not obstruct the attachment of parts such as the eaves unit to the side surface of the horizontal frame.

[0009]

【Example】

 A bracket 11 used in an embodiment of the present invention will be described with reference to FIGS. The bracket 11 according to this embodiment includes a base portion 12 and a receiving portion 14 for the inclined frame 13. The base portion 12 is plate-shaped and is fixed to the upper surface 17A of the flange 17 of the beam 16 that constitutes the floor frame 15. In the case of this embodiment, the floor frame 15 serves as a horizontal frame, and the upper surface 17A of the flange 17 serves as an upper surface of the horizontal frame.

The receiving portion 14 of the inclined frame 13 is formed continuously from one end of the base portion 12 and obliquely upward at an acute angle to the base portion 12. The angle of the receiving portion 14 with respect to the base portion 12 and the angle of the inclined frame 13 with respect to the horizontal plane are complementary to each other. Further, on the outside of the receiving portion 14 (on the side where the inclined frame 13 comes into contact), there are formed projections 19 at two positions to which the lower end of the inclined frame 13 is locked. The height position of these protrusions 19 corresponds to the height position to be attached to the receiving portion 14 of the inclined frame 13. These protrusions 19 are formed by, for example, pressing so that a part of the receiving portion 14 projects outward.

Inside the base portion 12 and the receiving portion 14, a plate-shaped reinforcing plate 21 joined to the both portions 12 and 14 is formed. Each of the base portion 12 and the receiving portion 14 is formed with two bolt insertion holes 22. The horizontal lengths of the base portion 12 and the receiving portion 14 are projected to the outside of the floor frame 15 when the bracket 11 is used for joining the inclined frame 13 and the floor frame 15 of the roof. The length of these 12,14 is arbitrary within this range as long as it has no length.

Next, a roof frame joining structure using the bracket 11 will be described. First, the protrusion 19 and the bolt insertion hole 22 are formed on a metal plate having a predetermined size, and then the metal plate is bent to manufacture the bracket 11 on which the base portion 12 is formed together with the receiving portion 14. . Next, in the production of the roof unit in the factory, with the bracket 11 positioned inside the floor frame 15, that is, the base 12, the receiving portion 14, and the reinforcing plate 21 all protrude to the outside of the floor frame 15. Without doing so, the base 12 is fixed to the upper surface 17A of the upper flange 17 of the beam 16 with bolts 23 and nuts 24.

Next, the tilted frame 13 is brought into contact with the receiving portion 14 of the bracket 11 such that the lower end portion of the inclined frame 13 is locked to the protruding portion 19 of the bracket 11, and then the bolt 23 and the nut 24 Fix 11,13. As a result, the inclined frame 13 is joined to the floor frame 15 via the bracket 11 of this embodiment. After this, a component 25 such as an eaves unit is attached to the side surface of the floor frame 15.

According to the joint structure of the roof frame according to the above-described embodiment, the base 12 of the bracket 11 of the upper flange 17 of the beam 16 forming the floor frame 15 is positioned with the bracket 11 positioned inside the floor frame 15. Since it is fixed to the upper surface 17A, the base portion 12 and the receiving portion 14 do not protrude to the outside of the floor frame 15. Therefore, by connecting the inclined frame 13 to the floor frame 15 through such a bracket 11, the bracket 11 becomes an obstacle when a component 25 such as an eaves tip unit is attached to the side surface of the floor frame 15. There is no.

Since the protrusions 19 are formed on the bracket 11, the lower end of the inclined frame 13 is locked to the protrusions 19 when the inclined frame 13 is joined to the floor frame 15. Can be kept, and the joining work becomes easy. Furthermore, since it is not structurally more complicated than the conventional bracket, it can be obtained at the same level as the conventional one in terms of manufacturing and cost.

In the above embodiment, the bracket 11 is manufactured by punching a metal plate and bending it. However, the bracket 11 may be integrally molded by casting or the like. Further, in the above embodiment, the base portion 12 and the receiving portion 14 are integrally molded, but a receiving portion separate from the base portion may be joined to the base portion by welding or the like to manufacture the bracket. Furthermore, although the protrusions 19 are formed in the above embodiment, the formation of such protrusions 19 is optional. The shape and the number of such protrusions 19 are arbitrary, and for example, one protrusion 19 may be formed continuously.

[0017]

[Effect of device]

 According to the joint structure of the roof frame according to the present invention, the bracket does not protrude to the outside of the horizontal frame, so that the bracket does not become an obstacle when attaching a part such as an eaves tip unit to the side surface of the horizontal frame.
