Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fixing structure for a roof panel, and more particularly to a structure in which a wooden roof panel is butted and fixed onto a steel beam made of end-shaped steel, end-shaped steel, H-shaped steel, etc. A fixing strip is integrally joined to the top surface of the steel beam, one roof panel is nailed through the nail hole provided in the fixing strip, and fixed, and overlapped on the top surface of the other roof panel. This relates to a structure in which both panels are butted together and fixed onto a steel beam by bending a fixing band plate and driving nails through nail holes provided in the bent pieces of the fixing band plate.

In a framework structure in which a small roof assembly is constructed by constructing seedwood or moya on a beam, hook-shaped or U-shaped bolt fittings are used to connect the steel beam and the wooden seedwood or moya. It is customary to fix the steel beams by anchoring them to the seedwood or moya.

However, when joining end faces of plate-shaped wooden panels to a steel beam by butting them together, it is not easy to fix them using these simple metal fittings.

That is, in order to use hook-shaped or U-shaped bolt fittings, holes are drilled in the plywood of both wooden panels, the bolt fittings are inserted into the holes so as to hold the steel beam, and then both panels are tightened with nuts. It is necessary to use a structure in which one roof panel is fixed by anchoring it to a steel beam, or by using metal fittings, and at the same time the other roof panel is also fixed at the joint surface of both panels. This is because it must be done. Moreover, the double hook-shaped or U-shaped bolt fittings are used for roof panel blowing.
There was a risk that the anchoring portion would stretch out due to the wind pressure, or that the bolt would fall off, leading to damage to the entire roof.

The present invention has been developed in view of the above points, and it allows two roof panels to be easily fixed to the steel beam L via fixing strips 17, and moreover, resists blow-up force by shearing the nails. , a fixed structure of strong roof panels and beams.

Embodiments of the present invention will be specifically described below based on the drawings.

FIG. 1 is a perspective view showing a state in which a fixing band plate 2 is erected on the upper surface 11 of a beam material, that is, a steel beam 1. FIG.

This steel beam 1 has a hook placed between the bundles of materials that make up the roof frame, and is constructed from a type of steel, a piece of steel made by butting two pieces of steel together, or a light LiH type steel. There is. On the upper surface 11 of this steel beam 1, that is, on the steel beam shown in -, a fixing strip 2 is erected on the flange surface. When used with mouth-shaped steels butted against each other, if the fixing strip plate 2 is sandwiched and welded between the lips of one double-ended steel, the fixing strip plate 2 and the steel beam l can be fixed in an extremely good condition. Become.

An appropriate number of nail holes 21, 2+, . . . are provided near the center of the roof panel thickness of the fixed strip plate 2 erected in this way. Further, a bent piece 23 is formed on the roof panel thickness side of the fixed strip 2, and this bent piece 23 is also provided with an appropriate number of nail holes 22.

Furthermore, a dividing groove 24 is provided in the vertical direction of the width of the fixing strip plate 2 of the bent piece 23, and the bent piece 23 is formed as necessary.
can be divided into folded pieces 23a and 23b.

Figure 2 shows that the fixing strip 2 explained in Figure 1 is the same steel beam 1.
It is a perspective view showing a state in which a plurality of pieces are erected on the top. In addition, a filler, so-called adjustment material 3, is laid on the steel beams 1''2 in order to make the joints of the roof panels to be fixed circular and smooth, and to eliminate gaps between the two members. This adjustment member 3 is a fixed strip plate 2.2 erected on the second side 11 of the steel beam l.
In order to avoid the
1... is provided.

Next, a case will be described in which a roof panel is fixed using the fixing strip 2 erected on the steel beam 1.

In FIG. 3('a), an adjusting member 3 having a trapezoidal cross section is provided on the steel beam 1''. Next, one end of the roof panel 4a is placed on the sloped surface of the adjustment material 3. In this state,
Nails are driven through the nail holes 21, 21, . As a result, the roof panel 4a is fixed to the steel beam l via the fixing strip 2.

Furthermore, as shown in Fig. 3(b), the adjustment material 3 on the steel beam l
Place one end of the roof panel 4b on.

At this time, since the abutting surfaces of the roof panels 4a and 4b are kept in close contact with each other, nailing or the like cannot be done to the abutting surface 42 of the roof panel 4b. Therefore, the bent piece 23 of the fixed band plate 2
is bent so as to overlap the top surface 43 of the roof panel 4b, and the nails 5 are inserted into the nail holes 22, 22... provided in this bent piece 23.
The roof pipe 4b is fixed by nailing it through the roof pipe.

In addition, if it is not possible to nail the mating surfaces of either the roof panel 4a or 4b,
As shown in the figure, a dividing groove 24 is provided in the bent piece 23 of the fixed band plate 2, and the bent small moons 23a and 23b of this bent piece 23 are bent alternately.

That is, when fixing the roof panels 4a and 4b as shown in FIGS. 4(a) to 4(c), the divided folded pieces 23a and 23b are folded so as to overlap the upper surfaces of the roof panels 4a and 4b. It is also possible to bend the nails and drive the nails 5 through the nail holes 22, 22, .

As a result, the ridge panels 4a and 4b are fixed to the steel beam l through the fixing strip 2.

In the above explanation, a plurality of fixed strips are provided on the beam L. However, the fixed strips of the wooden invention are not limited to the above description, and can be applied to the roof panels to be laid. It may have the same width as the width of the steel beam, or, as shown in FIG. 5, it may be constructed of a single fixed band plate spanning the entire length in the longitudinal direction of the steel beam.

Furthermore, as described above, dividing grooves can be provided in the fixed band plate 2 if necessary.

As described above, the fixing structure of the roof panel of the present invention is
The mating surfaces of one roof panel are nailed into place using the nail holes in the fixing strips provided on the two sides, and the bent piece of this fixing strip is bent onto the top surface of the other roof panel. This method allows wooden roof panels to be extremely easily fixed onto steel beams, and the roof panels are able to absorb the shearing force of the nails through the fixing strips on both the butting surfaces and the two surfaces. will be held by.

In other words, the fixed structure is extremely reliable in terms of strength.

Furthermore, by increasing or decreasing the number of needles, the horizontal shearing force of the fixed portion required as a design value can be easily set.

As described above, the roof panel fixing structure of the present invention is a fixing structure that is easy to construct, structurally resistant to structural damage, and sufficiently reliable against blow-up wind pressure.
