Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves unit mounting structure, and is particularly applicable to a building in which the eaves portion of the roof is unitized.

[0002]

2. Description of the Related Art In recent years, in building construction such as houses, in order to simplify the work at a construction site, prefabrication is being promoted in which each component constituting the building is unitized to be manufactured in a factory. For example, in a prefabricated house 50 that is a box-type unit-type building shown in FIG.
1 is formed by arranging and stacking 1 at the construction site, and the eaves tip portion of the roof is also unitized, and is formed by sequentially arranging a plurality of eaves tip units 52 in the outer peripheral direction of the box-type unit type prefabricated house 50.

By the way, the mounting structure of the eaves-point unit 52 is such that the eaves-point unit 52 is mounted and held on the eaves-section structural member formed on the upper portion of the frame 53 of the living room unit 51. Here, the eaves structural material is composed of an upper beam member 57 that constitutes the frame 53 and an upper end portion of a column 55 that connects these beam members.

That is, as shown in FIG. 5, the eaves edge unit 52 has a positioning groove 54 formed at its end and a nut 59 provided at a predetermined position. On the other hand, the positioning metal fittings 56 of the individual eaves unit 52 are fixed above the pillars 55, and the through holes 57A through which the bolts 58 can pass are provided at predetermined positions of the upper beam member 57 substantially parallel to the eaves unit 52. Has been.

The eaves edge unit 52 is positioned by engaging the positioning groove 54 with a dedicated positioning metal fitting 56 fixed to the pillar 55, and the bolt 58 penetrating the through hole 57A of the beam 57. Is fixed to the frame 53 by being screwed onto the nut 59. The positioning metal fittings 56, the through holes 57 </ b> A, etc. are factory-installed on the frame 53 in advance in correspondence with the location of the eaves unit 52.

[0006]

The eaves tip portion of the prefabricated house 50 as described above is formed by sequentially holding and fixing a plurality of eaves tip units 52 to the frame 53. At this time, the adjoining eaves tip units 52 need to have the same mounting height so as not to cause a step or the like.

However, since the individual eaves-point units 52 are not directly connected to the other eaves-point units 52 adjacent to each other, there is a possibility that their mounting positions do not relatively match. In particular, since each eaves tip unit 52 is attached to the frame 53 via a dedicated positioning metal fitting 56, there is a double positional error between the positioning metal fitting 56 and the frame 53 between adjacent eaves head units 52. And the relative positions may not match each other.

Due to such a mismatch in the relative mounting positions of the eaves edge units 52, not only a step or the like occurs at the eaves edge of the prefabricated house 50, but also a fixing error of the positioning metal fitting 56 occurs in the lateral direction. In this case, the adjacent eaves-edge units 52 interfere with each other and installation becomes impossible,
There is a risk that the eaves cannot be formed. Therefore, in the conventional mounting structure, it is necessary to correct the mounting position of each eaves-point unit 52 at the construction site, the original purpose of unitizing the eaves-point cannot be achieved, and a joiner or the like for concealing inconsistencies such as steps is required. Is required, which causes a complicated structure for mounting the eaves-edge unit.

It is an object of the present invention to provide a structure for mounting eaves end units in which a plurality of eaves end units arranged in a building can be surely and easily arranged at predetermined positions and work at a construction site can be simplified.

[0010]

SUMMARY OF THE INVENTION The present invention is a structure for mounting an eaves tip unit for continuously forming a plurality of eaves tips of a building, wherein the eaves tip unit to be attached is positioned to engage with the eaves part structural material of the building, The eaves tip unit to be retrofitted is engaged and positioned with the eaves tip unit to be retrofitted.

Further, it is preferable to have a holding means capable of holding and fixing each of the post-installed eaves tip unit and the eaves part structural material of the building at an arbitrary position. Here, as the holding means, for example, a structure in which an engaging plate or the like having a substantially sawtooth cross section is attached to the mutual abutting surfaces of the eaves unit and the eaves structural material of the building can be used.

[0012]

In the present invention as described above, since the rear eaves unit is positioned directly on the front eaves unit, the relative mounting positions of adjacent eaves units are reliably and easily determined. Will be positioned in position. Therefore, the correction work in the field work becomes unnecessary, and the step correspondence by the joiner becomes unnecessary, thereby achieving the above-mentioned object.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an eaves-edge unit mounting structure 10 of the present embodiment. In this embodiment, the eaves-edge unit 11 is positioned and held and fixed to the eaves-section structural material of the unit house that is a building, and the eaves-edge unit 13 is positioned to the eaves-side unit 11 and is fixedly held to the eaves-section structural material. It Here, the eaves portion structural material is composed of a beam member 12A and an upper end portion of a column 12B that form the frame 12 of the living room unit, or a beam member 12C and an upper end portion of the column 12B.

On the side of the eaves unit 11 of the frame 12,
A through hole 14 is formed in the beam member 12A, and a positioning fitting 15 is fixedly installed in the column 12B. On the other hand, the eaves unit 13
On the side, a through hole 16 is formed in the beam member 12C, and an engaging plate 17 is attached to the surface thereof.

On the frame 12 side of the eaves unit 11,
A positioning groove 18 and a nut 19 are provided. The eaves tip unit 11 as described above is positioned with respect to the frame 12 by engaging the positioning groove 18 with the positioning fitting 15, and is retained by the frame 12 by screwing the bolt 20 penetrating the through hole 14 into the nut 19. Fixed. In the eaves edge unit 11, a positioning metal fitting 21 is fixedly provided on the eaves edge unit 13 side.

On the frame 12 side of the eaves unit 13,
A nut 22 is provided on the surface of which an engaging plate 23
Is attached. Further, a positioning groove 24 with which the positioning metal fitting 21 is engaged is formed on the side of the eaves unit 11. Such an eaves tip unit 13 has the positioning groove 2
4 is positioned with respect to the eaves edge unit 11 by engaging the positioning metal fitting 21, and the bolt 25 penetrating the through hole 16 is fixed to the nut 22 via the engaging plates 17 and 23.
It is held and fixed to the frame 12 by being screwed into.

The engagement plates 17 and 23 are shown in FIGS.
As shown in FIG. 3, the surfaces facing each other are formed in a saw-tooth shape in cross section, and through holes 26 and 27 are formed in the substantially center thereof.
Of these, the through hole 26 is a long hole that is continuous in the vertical direction together with the through hole 16 of the beam 12C. The holding means 28 is constituted by these, and the eaves edge unit 13 is held and fixed to the frame 12 at an arbitrary position.

Next, a mounting procedure of the eaves edge units 11 and 13 configured as described above will be described.

First, the eaves edge unit 11 is lifted to the mounting position, and the positioning groove 18 is engaged with the positioning metal fitting 15 to position the eaves unit 11 with respect to the frame 12. Next, the eaves edge unit 11 is held and fixed to the frame 12 by passing the bolt 20 through the through hole 14 of the beam member 12A and screwing it into the nut 19. Next, the eaves edge unit 13 is lifted to the mounting position, and the positioning groove 24 is engaged with the positioning metal fitting 21 to move the eaves edge unit 11
Position relative to. Then, at that position, the engagement plates 17 and 23 are engaged with each other, and the bolt 25 is attached to the beam member 1.
The eaves tip unit 13 is held and fixed to the frame 12 by penetrating the through hole 16 of 2C and the through holes 26 and 27 of the engaging plates 17 and 23 and screwing and tightening the nut 22.

According to this embodiment as described above, there are the following effects. That is, since the eaves-edge unit 13 which is the eaves-edge unit to be retrofitted is positioned on the eaves-edge unit 11 which is the eaves-edge unit to be retrofitted, the attachment height and the like always correspond to the attachment height and the like of the eaves-edge unit 11. Can be made

The eaves-edge unit 13 is positioned by the eaves-edge unit 11, but since the weight of the eaves-edge unit 11 is supported (held and fixed) by the frame 12 through the bolts 25, the eaves-edge unit 11 is required to have a particularly high strength. Not
The structure can be substantially the same as the existing eaves unit. Also at this time, the eaves unit 1 is held by the holding means 28.
3 can correspond to any mounting height of the eaves unit 11,
It is possible to always match the mounting height.

Further, it is not necessary to raise the height position accuracy of the positioning metal fittings for each eaves-edge unit more than necessary, and the production efficiency of the frame 12 in the factory can be improved.

The present invention is not limited to the above-mentioned embodiments, but is improved within a range in which the present invention can be achieved.
Modifications and the like are included in the present invention.

For example, in the present embodiment, the holding means 28 is configured to include the fitting plates 17 and 23 having a substantially saw-toothed cross section, but the cross sectional shape, the number of protrusions, the pitch, etc. are arbitrary. Other than that, for example, bolts 25 having a substantially wavy cross section, a substantially uneven cross section, etc., which are engaged with each other by screwing and tightening the bolts 25 on the nut 22, can be used.

Further, the holding means 28 may be one in which the friction coefficient of the mutual abutting surface between the frame 12 and the eaves-edge unit 13 is high. In short, the bolt 25 is screwed and tightened to the nut 22. It is sufficient that the eaves unit 13 can be held and fixed to the frame 12 at an arbitrary position. However, with the configuration of this embodiment, the arbitrary position of the eaves edge unit 13 cannot be moved in the vertical direction unless the bolts 25 are loosened to separate the fitting plates 17 and 23 from each other by a predetermined distance. Not only the work is easy, but also the holding and fixing is strong.

On the other hand, the positioning metal fittings 15 and 21 may be other than those of this embodiment, and in short, if the eaves unit 11 can be positioned at a predetermined position with respect to the frame 12 and further with respect to the eaves unit 11. Well, its form, position, number, etc. are arbitrary.

Further, in the present embodiment, the eaves edge unit mounting structure is arranged at right angles to the corners of the building, but it is also possible to apply a structure in which the eaves units are continuously arranged in a straight line. Even when the eaves tip units are not aligned at the same height but need to be set at the predetermined mounting position, the fixing position and the forming position of the positioning metal fitting and the positioning groove can be appropriately selected to be applied. In short, the present invention has an excellent effect that the installation can be surely and easily performed by applying each eaves-edge unit installed adjacent to the building at a predetermined height and position.
