Abstract

(57) [Summary] [Purpose] By eliminating the beams, it is possible to create a truss roof structure that can use the attic space. [Structure] A space where the attic can be used by the three-dimensional truss frame structure in which plane trusses of king posts are tilted from the four sides to the roof slope to form a pyramid-shaped solid, and they are composed of a flat palm, a corner palm, and a fire hammer It features a skeleton with.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a three-dimensional truss frame-less shed structure.

[0002]

[Prior art]

 In order to create a wide space with a span of 6 to 8 m using a conventional roofing system, a plane truss with a left and right opposite palms, such as a king post, is used vertically, and the girder root is constructed by simply arranging them in parallel. Alternatively, the above-mentioned truss was used for square roofs and ridged nunners by using a frame construction method in which one flat joint palm truss that hangs at right angles and a corner joint palm truss that hangs diagonally are added. In each of the frame construction methods, since there are horizontal beams and land beams in addition to the joints, the space inside the attic could not be used, and high pillars were required on the outer periphery to secure a sufficient ceiling height as a living room. In particular, because the eaves height is restricted in a 3-story urban building, in order to create a large space, if the pillars are short, the conventional truss construction method cannot use the interior of the shed and the ceiling height is insufficient. There was a drawback that it could not be used in the next room.

In the conventional shed frame construction method, a cane is necessary because the middle portion between the flat trusses that are formed easily moves in the horizontal direction and is easily twisted. In order to make a building strong in the event of a natural disaster such as a typhoon or an earthquake, it was necessary to secure horizontal rigidity by installing separate diagonal members such as a cane under the ridge, spider braces, and flming.

[0004]

[Problems to be solved by the device]

 The problem to be solved is that when building a large space with a frame, there are horizontal members and beams, so if the surrounding columns are short, a sufficient ceiling height cannot be obtained as a living room, and the truss hut structure is used as a space. It was a point that could not be used.

[0005]

[Means for Solving the Problems]

 The present invention aims to use a quadrangular pyramid-shaped internal space by a three-dimensional truss frame structure in which plane trusses of king posts are tilted from the four sides to the roof slope to form a three-dimensional structure, and they are composed of a flat palm, a corner palm, and a fire hammer. Realized a truss hut with it.

【Example】

 1 is a perspective view of the present invention seen from above, FIG. 2 is a plan view, and FIG. 3 is a perspective view looking up from the ceiling. 1 to 3 are timber diagonal timbers, 4 are purlins, 5 are purlins, and 6 are girders.

On the square-shaped girder 6, the flat palm 3 is laid in the direction orthogonal to the four-sided girder, and the corner palm 2 is laid in the diagonal direction. Connect the two heads where the flat and palm corners meet together with a purlin 4. A fire hitting palm 1 which is orthogonal to the middle portion of the corner palm is incorporated. Connect the joints of the corner and palm hitches and the middle part of the flattened palm, and install the purlin 5 parallel to the girder. All wooden members are assembled and joined together, and are fastened with axial bolts.

Originally, the ganging post is a compression material, but when it is used as a flat pallet for a three-dimensional frame constructed by sloping to the roof slope, it becomes a tension material and acts to lift the middle part of the girder. Is a fine material in time. The corner joint and the fire joint palm, which are orthogonal to each other between the compression members, form triangular pyramids that are difficult to deform at the corners of the roof truss and stretch them, so that the roof truss is transformed into a highly rigid three-dimensional truss frame. As for the corner joint palm, the middle part is supported by the fire joint palm, so it can be made with economical thin material. There is only one purlin lined up along the girder, and there is no need for a purlin, which was necessary in the past. Since the quadrangular pyramid-shaped three-dimensional truss is laterally formed on the roof surface, the entire skeleton works together not only for vertical loads but also for horizontal loads, and the rigidity of each roof member is resistant to deformation and twisting. It becomes a hut space. The roof girder, which is a set of truss planes that is invariant to the triangle, is an integral part of the frame that does not easily deform into a rhombus on the horizontal plane. Therefore, the columns and walls of the frame are resistant to twisting and have high horizontal rigidity and seismic resistance. Building can be made possible.

[0009] Since the members can be carried to the site by a member that is easy to hold and can be easily transported by car, and after being grounded, they can be lifted using the crane, so that workers do not have to do dangerous work on a high roof. You can build it safely.

[Effect of the invention]

 As described above, the roof truss of the present invention not only allows a space having a span of 6 to 8 m, but can also utilize a wide attic space having a quadrangular pyramid shape with an elevated inside. Especially in a three-story building where the height of the eaves is restricted, a room with a sufficient ceiling height can be built even if the surrounding columns are short, and in the future it will be possible to move the partitions freely, which is a structural feature. Not only the sex, but also the habitability can have a great effect.

When the shed structure of the present invention is made of wood, it becomes a very lightweight and economical framework. It can be used not only on wooden frames but also on steel or reinforced concrete columns and walls.
