[Detailed Description of the Invention] [Industrial Application Field] The present invention fixes a mounting plate of a hanger on the top plate of a metal rafter, and attaches a ridge side roof plate to a locking portion protruding from the mounting plate. This relates to a horizontal thatched roof in which the roof is roofed from bottom to top while locking the ridge-side engaging portion of the eave-side roof plate that engages with the eave-side engaging portion of the roof plate.

[Conventional technology]

Figure 7 shows that in this type of horizontal roof structure,
1 is a partially cutaway perspective view showing a known means for fixing a hanger to a metal rafter; FIG.

In the figure, 1 is a metal rafter, and 2 is a hanger fixed on the top plate 1a of the rafter 1. On the top plate 1a of the rafter 1 are cut and raised pieces 1b, 1 for the eave side and ridge side.
c is formed protrudingly.

The hanger 2 is made of a molded metal plate, and has a locking part 4 that is bent upward at the eave side edge of the mounting plate 3 and that engages with the ridge side edge of the roof board (not shown). A pair of horizontally elongated holes 3a and 3b are formed in the mounting plate 3 on the eaves side and the ridge side.

Then, the locking part 4 of the hanger 2 is hooked to the ridge side engaging part of the roof plate, and the two horizontally elongated holes 3 formed in the hanger 2 are inserted.
a, 3b through the cut and raised pieces 1b, 1c, and hit both cut and raised pieces 1b, 1c with a hammer or the like in the direction of the arrow to bend them so that they face each other on the surface of the mounting plate 3, thereby forming the mounting plate. 3 was clamped onto the top plate 1a of the rafter 1, and the hanger 2 was fixed onto the top plate 1a. Further, as shown in the figure, screws 5 are arranged between the holes 3a and 3b as necessary, and the screws 5 are used to screw the top plate 1a.

[Problem to be solved by the invention]

However, in the case of the above fixed structure, 1
When fixing each hanger 2, the two cut-and-raised pieces 1b and 1c provided on the rafter 1 must be bent, and a large number of hangers must be used especially for horizontal roofs. Therefore, there was a problem that the overall effort was enormous and the workability was poor.

In addition, when a wind-blown load acts on the roof plate, in this structure, a force is applied to lift the locking part 4, and the eave-side cut and raised piece 1b of the rafter 1 is the reaction force point to this point of action. However, due to its structure, it is bent away from the locking part 4, so the hanger 2
There was also the problem that the support strength for each load was low, and therefore a large number of hangers were required.

The present invention solves the above problems,
To provide a horizontal roof that simplifies the work of fixing hangers to rafters and increases the strength against the load applied to the hangers in the peeling direction.

[Means to solve the problem]

In order to achieve the above-mentioned object, the present invention provides a roof in which metal roof plates are sequentially roofed on supporting members such as rafters 1 from the eaves side to the ridge side via hangers, and includes the following steps: At the installation position of child 2,
A window hole 1d is opened, and a cut-and-raised piece 1c is formed at a position on the ridge side of the window hole 1d, and a cut-and-raised piece 1c is formed on the mounting plate 3 of the hanger 2, and is sloped downward and extends over the eaves of the window hole 1d. A locking piece 3c that locks with the side end 1f is provided protrudingly, a notch 3d is formed at the ridge side end of the mounting plate 3, and a locking piece 3c is provided at the eave side end 1f of the window hole 1d. A structure in which the cut and raised piece 1c is inserted and abutted, the cut and raised piece 1c is engaged with the notch 3d, the cut and raised piece 1c is bent onto the mounting plate 3, and the mounting plate 3 is sandwiched on the top plate 1a. And so.

[Function] Since the horizontal roof of the present invention has the above-mentioned configuration,
When fixing one hanger to the rafters, fixing is completed by bending only one cut and raised piece 1c on the ridge side.
Workability can be significantly improved.

In addition, when the wind blows up the load,
Since the locking portion of the hanger, which is the point of action, and the locking piece, which is the point of reaction force, are close to each other, the support strength of the hanger against the load is increased.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings. In the embodiment, the same reference numerals are used to describe the same or corresponding parts as in the conventional example.

1 to 4 show a first embodiment of the present invention.

First, Figure 2 shows the overall configuration. 1 is a metal rafter arranged in a straight line from the eave side to the ridge side, 2 is a hanger fixed at appropriate intervals along the longitudinal direction of the rafter 1. , 6 and 8 are elongated eave side and ridge side roof plates made of metal plates installed perpendicularly to the upper part of the rafter 1, and 10 is a roof plate laid on the rafter 1, and each of the roof plates 6, 8 is a base plate made of wood wool board or the like.

The rafter 1 is a long piece made of a steel plate with a hat-shaped cross section, and as shown in FIGS. 1 and 4, the rafter 1
There is a window hole 1d on the eaves side of the top plate 1a, and this window hole 1
A tongue piece 1e extending downward from the ridge side end of d, and a cut and raised piece 1c on the ridge side are formed at positions corresponding to the hangers 2, which will be described later. 1f is the eave side end of the window hole 1d.

On the other hand, the hanger 2 is made of a relatively thick press-formed steel plate, and includes a mounting plate 3 for attaching to the top plate 1a of the rafter 1, and a mounting plate 3 that extends upward toward the edge of the eave side. It consists of a locking part 4 bent into a hook shape. As shown in FIGS. 1 and 3, at a position close to the locking part 4 side of the mounting plate 3, the ridge side end is made into a connecting part by press punching and is approximately directed downward to the eave side. A locking piece 3c inclined at an angle of about 45° is formed, and a notch 3d opening in a concave shape is formed by punching at the ridge side end of the mounting plate 3.

The locking portion 4 includes a rising portion 4a bent upward from the lower end of the mounting plate 3 in an upright state, and a rising portion 4a.
Surrounding portion 4 curved in a “T” shape at the upper edge of a
b, and a locking portion 4c which is located at the eaves side end of the surrounding portion 4b and is bent downward.

The locking piece 3c is provided with a protrusion 3e extending downwards to the connecting portion with the mounting plate 3, and a portion extending from the mounting plate 3 to the lower portion of the locking portion 4 is provided with a protrusion 3e. A plurality of protrusions 2a are provided to protrude toward the longitudinal surface, and these protrusions 2a, 3e reinforce each part to prevent deformation or breakage when excessive external force is applied.

Ridge side engagement part 7 of eave side roof board 6 of metal roof board
As shown in FIG.
A bent part 7c with a locking part 7b is formed from the upper end of a, and the bent part 7c further includes a horizontal U-shaped holding part 7.
d is formed. Then, the tip of the holding portion 7d expands upward toward the eaves, and this tip engages with the inside of the locking portion 4c of the locking portion 4, thereby locking the ridge side engaging portion 7 to the hanger 2. ing.

On the other hand, the eave side engaging portion 9 of the ridge side roof board 8
consists of a hanging part 9b bent downward at a substantially right angle from the face plate part 8a, and a stepped bent part 9c bent from this hanging part 9b toward the ridge side, and furthermore, this bent part 9c has the above-mentioned holding part. A horizontal U-shaped locking portion 9d held by the portion 7d is integrally formed.

In the above configuration, in order to fix the roof plate onto the rafter 1 via the hanger 2, first pull the locking part 4c of the hanger 2 onto the tip of the holding part 7d of the ridge side engaging part 7. Then, the locking piece 3c of the mounting plate 3 is inserted into the window hole 1d formed in the top plate 1a and engaged with the eaves side end 1f of the window hole 1d. Next, in this state, attach the mounting plate 3 to the top plate 1a.
If installed on top, the notch 3d will engage with the cut and raised piece 1c, and by hitting only this cut and raised piece 1c with a hammer or the like and bending it toward the eaves, the mounting plate 3 will be attached to the top plate 1a.
This allows the ridge-side engaging portion 7 of the roof board and the hanger 2 to be fixed onto the rafter 1.
Then, the eaves-side engaging portion 9 is engaged with the ridge-side engaging portion 7, so that the roof is successively horizontally covered.

In addition, in this embodiment, as shown in FIGS. 1 and 4, a structure in which the screw 5 is screwed in between the locking piece 3c and the notch 3d to fix it to the top plate 1a can also be used. Furthermore, the fixing strength can be increased.

When the rafters 1 and hangers 2 of the present invention are used to cover the roof sheets 6 and 8 as described above, the hanging portions 9a and the rising portions 7a are almost on the same plane, even under rainstorms. Rainwater is less likely to enter through the contact area. Moreover, since the engagement structure between the eave side engagement part 7 and the ridge side engagement part 9 is bent and engaged above the joint between the hanging part 9a and the rising part 7a, rainwater is surely prevented from entering. can be prevented.

Note that the eave-side end of the roof board located closest to the eaves and the ridge-side end of the roof board located closest to the ridge are treated by conventionally known means.

FIGS. 5 and 6 show a second embodiment of the present invention, and parts corresponding to those in the first embodiment are designated by the same reference numerals and explanations thereof will be omitted.

This embodiment differs from the first embodiment in the following points. That is, first, a step portion 4d is formed between the rising portion 4a of the locking portion 4 of the hanger 2 and the surrounding portion 4b. Therefore, the eave-side end of the base material is supported on the upper part of this step 4d, and the ridge-side end of the base material 10 is engaged and supported on the lower part of this step 4d. Next, the locking piece 3c provided on the mounting plate 3 is attached to the eave side end 1.
This is the point where it is bent directly below the locking part 4 with f as the connecting part.

The above two configurations are different from the first embodiment, and the others are substantially the same, and by using this hanger 2, the base material 10 and the top plate 1a of the rafter 1 can be almost It becomes possible to form a triangular air layer, making it possible to further enhance soundproofing and heat insulation effects.

Although each embodiment of the present invention has been described above, it is clear from the above description that the above-mentioned objects of the present invention are effectively achieved. Furthermore, since changes can be made to the configuration without departing from the spirit and scope of the invention, the above description is merely exemplary;
It should not be understood in any limited way.

The claims are intended to cover every feature of the invention and all matters that may be omitted as a matter of language.

〔Effect of the invention〕

As explained in detail in each embodiment above,
According to the present invention, when fixing one hanger to a rafter, there are essentially two fixing locations, but fixing is completed by bending only one cut and raised piece on the ridge side during work. Therefore, workability is extremely improved compared to the conventional structure in which two parts are bent and fixed.

In addition, in the case of the present invention, when a wind-blown load is applied, the support strength against the load of the hanger is improved because the locking part of the hanger, which is the point of action, and the locking piece, which is the point of reaction force, are close to each other. This has the excellent effect of increasing the fixing strength of the roof and improving safety against wind and the like.
