Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to the structure of synthetic corner timbers used in hipped roofs, etc., and more specifically relates to the structure of synthetic corner timbers used in hipped roofs, etc. The present invention also relates to the structure of a synthetic corner block in which a support beam is fixed to the outer surface of the half corner block.

(Prior art and problems) Conventionally, hipped roofs have been widely used as a roof shape that emphasizes the stability of the entire building, but most of them have frame structures, so-called corner and valley timbers with distributed taruki attached to them. It has a structure with angled corners.

Therefore, it is difficult to fit together the corner and valley wood and the distributed roof, and it can only be done by a carpenter with special skills.The construction period also takes a long time, and the cost is higher than that of other gable roofs. It was hot.

Furthermore, in these framework structures, it is necessary to cut out the corner timbers themselves at the corners where the outer wall protrudes and the main building is housed, and this cross-sectional notch weakens the strength of the interior, which is a major problem with hipped buildings using frame structures. It had become a drawback.

(Object of the invention) The present invention has been made in view of the above two points,
To provide a corner piece for constructing a hipped roof with panels, and to provide a corner piece that can secure sufficient strength for fitting the corner piece, an external wall protruding corner, and a main house.

(Specific Means for Solving the Problems) Hereinafter, the synthetic corner beam of the present invention will be explained in detail based on the drawings.

FIG. 1 is a front view of a composite corner block 1 according to the present invention.

This synthetic corner tree 1 has a substantially trapezoidal half corner tree 20, 2.
0, the stiffening plate 30 sandwiched between them, and the support beams 40, 4 fixed to the outer surfaces of the half-corner beams 20, 20.
Consists of 0.

Moreover, below the stiffening plate 30, this stiffening plate 30
A plywood board 50 of approximately the same thickness is similarly sandwiched.

FIG. 2 is a side view with a part of the composite corner block 1 omitted. As you can see from this figure, composite corner tree 1
is a so-called long material that is long enough to span in the axial direction from the building ridge, and a purlin receiving recess 11 is formed on the lower surface of one end to serve as a connecting part with the main building, and there are also holes at required locations on the lower surface. A girder receiving recess 12 is provided which serves as a connecting part with the outer wall protruding corner.

Moreover, the upper surface of the purlin receiving recess 11 is cut out at a certain angle in order to arrange a corner beam at the end of the purlin, and the other end is also cut out at a certain angle in order to attach a nose comb or the like.

The structure of the composite corner bar 1 having the above configuration and its construction procedure will be explained in more detail with reference to FIGS. 3 to 6.

FIG. 3 is a front view of the synthetic corner block 1 disassembled into its constituent members.

That is, the half-corner wood 20 is a long piece of material having a substantially trapezoidal cross section and formed of an upper side 21, a lower side 22, an outer side 23, and an inner side 24. The angle between the upper side 21 and the inner side 24 is arbitrarily formed according to the slope angle of the panels installed on the girder side and the girth side.

Further, the lower side 22 is formed approximately parallel to the upper side 21,
Moreover, the outer side 23 is the upper side 21 and the lower side 22.
It is formed almost at right angles to.

A pair of half corner trees 20, 20 formed in this way
A stiffening plate 30 is disposed above the inner side 24 between them.

As the stiffening plate 30, a flat iron plate, a synthetic resin material, or the like is used. In any case, it is best to use a material that has high shear and bending strength against external stress in the in-plane direction.

The stiffening board 30 is a long piece of material with approximately the same length as the half-corner wood 20, and nail holes 31, 3 are pre-drilled in its main parts.
1... is drilled.

On the other hand, below the stiffening plate 30 is a plywood plate 5 of approximately the same thickness.
0 is placed. Since this plywood 50 is provided within the inner side 24 of the half-cornered wood 20, the sum of the backs of the stiffening board 30 and the plywood 50 is made equal to the height of the inner side 24.
Also, it is made of a long material similar to the stiffening plate 30.

In the above state, the stiffening plate 30 and the plywood 50 are sandwiched between the pair of half-corner beams 20, 20.

On the other hand, the support beam 40 fixed to the outer side 23 of the half-corner 20 has a constant width because the end of the roof panel is placed on its upper side, and its upper surface is connected to the half-corner 20.
It is fixed in a state that is substantially parallel to the upper side 21 of the roof panel and has a step corresponding to the thickness of the roof panel.

In order to construct the composite corner block 1 according to the present invention using the above-mentioned components, first, as shown in FIG. At this time, the guide hole 2 has a smaller diameter than the nail holes 31 of the stiffening plate 30 and is aligned concentrically.
1 and 21 are drilled in the half corner tree 20.

Next, as shown in FIG.
Connecting nails 70, 70 are driven from 1, 21 and nailed. Then, insert the plywood 50 from below the stiffening board 30, and attach the mounting nails 80 from the outer side 23 of the half corner wood 20.
is driven in and the plywood 50 is sandwiched between the two half corner pieces 20, 20.

Further, as shown in FIG. 6, fixing nails 90, 90 are nailed to both outer sides 23, 23 of the half-corner beams 20, 20, with their lower sides 22, 22 flush with the lower side of the support beam 40.

In addition, the mounting nails 80 and the support beams 4 to which the plywood 50 is nailed are attached.
It is also possible to use the same nail as the attachment nail 90 for fixing the plywood 50 and the support beams 40, 40.

In the composite corner block 1 configured as described above, the purlin receiving recess 11 and the girder receiving recess 1 are provided at required locations on the lower surface.
form 2. A stiffening plate 30 is placed on the bottom surface of the composite corner block 1.
Since the plywood 50 is sandwiched instead of the plywood 50, it is possible to easily cut out the half corner pieces 20, 20, the support beams 40, 40, and the plywood 50 to form each recess.

FIG. 7 is a partially omitted perspective view showing a state in which the roof panel 100 is laid on the composite corner timber 1.

That is, the upper side 21 of the composite corner block 1 and the roof panel 1
The upper surface 101 of 00 has the same slope, and the end surface 102 of the roof panel 100 has the same slope as the outer side 2 of the composite corner block 1.
3 is placed on the upper side of the receiving crosspiece 40 in a state in which it is in contact with the support member 3.

In this way, the purlin receiving recess 11 and the girder receiving recess 12 of the composite corner block 1 of the present invention are respectively fitted into the main building or the outer wall protruding corner and arranged as a corner ridge, and the composite corner block 1,
1... Roof panel 100 on the gable side and the girder side,
The roof plan in Fig. 8 shows the state in which the pipes 100... are installed.

The synthetic corner timber 1 of the present invention is not simply used for a corner ridge, but may be used as a valley timber for a so-called valley ridge. At this time, the receiving pier 40,
Reference numeral 40 is attached with the upper sides 21, 21 and the lower sides of the half corner timbers 20 flush with each other, so that the so-called half corner timbers 20, 20 are in an inverted state. Furthermore, the stiffening plate 30 and the plywood 20 are also placed in opposite positions.

As mentioned above, in order to arrange the synthetic corner pieces 1 in the girder side direction and the girder side direction, the purlin receiving recess 11 and the girder receiving recess 12
Even if the upper part of each recess is provided with a stiffening plate 30
Since they are integrally nailed together, they have sufficient rigidity against external stresses such as shearing and bending.

Moreover, these purlin receiving recesses 11 and girder receiving recesses 1
2 to an arbitrary size at an arbitrary location, it can be easily cut out because the half-corner wood 20, the support beam 40, and the plywood 50 are each made of wood.

(Effects of the Invention) As described above, when constructing a hipped roof using the synthetic corner beams of the present invention, it is possible to form a hipped roof by laying roof panels extremely easily compared to a framework structure. It is possible to form a concave part by arbitrarily cutting out the corner pieces instead of the height, and there is no problem of weakening of the joint due to cross-sectional defects, making the construction of hipped roofs extremely efficient and increasing the strength of the roof. It will be possible to secure ten copies.
