Description

[Detailed description of the invention] [Industrial application field] This invention enables easy and reliable connection of supports and eaves in simple buildings and structures by means of connecting fittings.
Moreover, the present invention relates to an eave connecting structure that can be connected without wobbling in the connecting portions.

[Conventional technology]

Sunrooms and extension rooms are being installed in houses in response to modern demands such as energy conservation and spacious living spaces.

In particular, when expanding a sunroom, the pillars of a pillar-built balcony installed in a two-story house are used to install the sunroom under the balcony.

The construction materials for these sunrooms and extension rooms are:
Most of the buildings are made into units, and the main frame members such as pillars, eaves, vertical frames, and horizontal frames are made of aluminum,
Alternatively, drawn materials having a certain cross-sectional shape made of steel are used, and these are connected and assembled using a relatively simple connection method.

However, the eave that spans the upper part between the pillars,
A very simple method has been adopted in which a notch equal to the outer cross-section of the eaves is formed on the faces of the opposing pillars, and the ends of the eaves are fitted and fixed into the notches.

[Problem that the invention attempts to solve]

The above-mentioned sunrooms and extension rooms are relatively simple constructions and structures, and are expected to increase in the future in Japan. The method is
Not only does this weaken the strength of the support column, but also the connection parts become loose due to various reasons during long-term use, and as a result, there is a high risk that gaps and water leaks will occur in various parts.

In view of the current situation, the purpose of this invention is to provide an eaves connecting structure that allows easy connection of the eaves to the support and does not cause any looseness at the connecting portion.

[Means for solving problems]

In order to achieve the above object, the eave connecting structure of this invention is formed of a cylindrical elongated body with a substantially square cross section obtained by connecting the front side plate and the rear side plate to the upper plate and the lower plate, and The board slopes downward toward the front side plate to form a downward bent edge, and a horizontal protruding edge provided in the middle of the bent edge is integrally connected to the front side plate and opens upward. A plate-shaped body is bent at right angles to form two plate parts at both ends of the eaves, which is formed by forming grooves with a constant gap between them, and an engagement groove with a constant gap that opens downward on the lower back side of the groove. The structure is connected to opposing surfaces of a pair of parallel pillars by a pair of connecting metal fittings, and one plate part of the connecting metal fittings has a shape that can be fitted into the open end of the eaves. The other plate part is shaped so that it can be fitted along the inner surface of the front side plate of the eave, and when fitted into the eave, the one plate part A notch of a predetermined width formed downward from the upper edge along the bent edge of the eaves supports the bent edge of the eaves, and a bolt hole for connecting the eaves provided in the other plate The other plate part is bolted to the front side plate of the eave using a fixing nut provided on the plate surface facing the rear side plate direction of the bolt hole.

[Effect]

The eave connecting structure of this invention consists of two plate parts bent at right angles to the opposing faces of a pair of parallel supports.One plate part of the fitting is fixed with bolts, and the other plate part is fixed with bolts. When the plate part is inserted into the open end of the eave eaves made of a long cylindrical body with a substantially square cross section and bolted to the front side plate of the eaves, the upper plate that makes up the eaves is attached. Insert the end of the bent edge into the notch formed in one plate of the connecting fitting and engage it, and fit the upper edge of the other plate into the engagement groove formed in the eaves. By fixing with bolts, the pillar and the eaves can be reliably connected without loosening or rattling.

〔Example〕

Hereinafter, the eaves connecting structure of this invention will be described in more detail with reference to the accompanying drawings.

The eave connecting structure of this invention uses the connecting fitting 1 shown in Figure 1 between a pair of pillars 10 that stand side by side as shown in Figure 2 (one of the pillars is not shown). The eave 12 of the structure shown in FIG. 2 is horizontally spanned and fixed.

Each of the pillars 10 is a rectangular tube-shaped elongated body with a hollow portion A formed therein, and reference numeral 11 denotes an opposing surface between the pillars 10.

The eave 12 is attached to the front side plate 1 as shown in FIG.
4 and the rear side plate 15 are connected to the upper plate 13 and the lower plate 16, and the upper plate 13 is an elongated cylindrical body with a generally square cross section and has a hollow part B inside. 15 side toward the front side plate 14 (in the example, the slope is 10° with respect to the horizontal)
The curved edge 18 is inclined with a slope of 100 mm and then downwards.

In the middle of this bent edge 18, a projecting edge 19 is provided that projects horizontally in the direction of the front side plate 14, and the side edges of this projecting edge 19 are integrally connected to the front side plate 14. Therefore, a groove 17 that opens upward and has a constant gap, and an engagement groove 20 that opens downward and has a constant gap are formed on the lower back surface of the groove 17.

The side of the rear side plate 15 of the upper plate 13 has an overhanging edge 13
A, and the top plate 13 (including the overhanging edge 13a) having such a downward slope has a front frame portion (not shown) of the roof plate with a downward slope (approximately 10° slope).
It is fixed with a .

In addition, projecting edges 16a and 16b are formed at the front and rear of the lower plate 16 and are bent downward in a hook shape, and a sliding door is provided in the lower space C surrounded by the lower surface of the lower plate 16 and the projecting edges 16a and 16b. It is configured to attach a frame of a rail (not shown), etc., and a narrow groove 21 for fixing a curtain rail is formed in the rear side plate 15 of the eaves 12 in the longitudinal direction, recessed in the hollow part B. has been done.

Note that two upper and lower bolt holes 22, 22 are formed at both ends of the front side plate 14, respectively.
The bolt holes at one end are not shown.

On the other hand, as shown in FIG. 1, the connecting fitting 1 consists of a plate part 2 that is fixed to the support column 10, and a plate part 3 that is formed perpendicularly to the side edge of this plate part 2 to connect the eaves 12. It is composed of

These plate parts 2 and 3 are obtained by bending substantially one plate-like body at right angles with the bent edge 8 as a boundary.

The plate portion 2 connected to the pillar 10 has a rectangular shape, but is shaped so that the upper edge 7 is directed toward the central bent edge 8 so that it can fit into the hollow B in the opening end of the eaves 12. It has a downward slope (a slope of 10 degrees from the horizontal), and then a notch 6 is formed in the part along the bent edge 8, and the width and depth of this notch 6 are as follows: has been done.

In other words, as shown in FIG. It has a depth such that it is supported in contact with the edge 9, and two bolt holes 4, 4 are formed in the plate surface of the plate part 2, upper and lower.

The plate part 3 is composed of a square plate whose upper edge 9 does not form a slope, and has two bolt holes (not shown) like the plate part 2, but it is difficult to attach it to the eaves 12. Therefore, in the bolt holes on the surface facing the rear side plate 15, that is, on the side of the plate part 3 that sandwiches the right angle formed by the plate parts 2 and 3, fixing nuts 5, 5 made of hop nuts are installed. It is provided.

The hop nut has an internally threaded nut fixed to one side of the bolt hole, and when the bolt is screwed in, the nut itself can be tightened by preventing rotation.It supports a normal nut when tightening the bolt. This hop nut is advantageously used when tightening bolts from the outside in a narrow space where it is impossible to tighten.

The following is an eave 12 made using such a connecting fitting 1.
A method of connecting between the supports 10 will be described.

First, the plate portions 2 of the connecting fittings 1 are brought into contact with the opposing surfaces 11 of the pair of columns 10 standing side by side, and the bolt holes 4, 4 of the plate portions 2 are aligned with the bolt holes drilled in the opposing surfaces 11 of the columns 10. , hollow part A of the support column 10
The bolt 2 is attached to a fixing nut consisting of a hop nut (both the bolt hole and this fixing nut are not shown) attached to the part of the bolt hole that opens inward.
3 and 23 are inserted and screwed together and fixed to the support column 10.

Due to this installation, the plate part 3 of the connecting fitting 1 protrudes from the opposing surface 11 of the support column 10 at right angles toward the space between the respective support columns, so that the plate part 3 is inserted into the hollow part B from the end opening of the eaves 12. The end of the bent edge 18 formed by the bending of the upper plate 13 of the eaves 12 is inserted into the notch 6 formed in the plate part 2, and is engaged.
The upper edge 9 of the plate part 3 is fitted into the engagement groove 20 formed in the eaves 12.

After that, from the outside of the front side plate 14 of the eaves 12, bolts (not shown) are screwed into the fixing nuts 5, 5 through the bolt holes 22, 22 drilled at both ends of the front side plate 14, respectively. The eave 12 is fixed to the support column 10 by tightening.

By applying such a connecting fitting 1 to the opposing faces of other supporting columns and connecting the other ends of the eaves 12 in the same manner as described above, it is possible to easily connect the eaves 12 between each column. Can be connected to.

In this way, the eaves 12 is connected and fixed to the pillar 10.
The end of the bent edge 18 fits into the notch 6 of the connecting fitting 1, and the upper edge 9 of the engaging groove 2 has an elongated shape.
0 and is abutted and supported by the protruding edge 19,
Reliable connection between the pillar 10 and the eave 12 is achieved, and there is no possibility of loosening or rattling during use, and in particular, the notch 6 prevents the eave 12 from shifting in the horizontal direction. This makes it possible to sufficiently withstand such downward loads, thereby achieving a strong connection.

By using this connecting fitting 1, the eave 12 whose upper plate 13 is inclined at a predetermined slope can be easily and reliably connected to the pillar 10, so that the roof plate can be reliably installed at the desired inclination angle. It can also be easily attached to a sliding door or the like in the lower space C of the eaves 12.

Note that the groove 17 formed in the eaves 12 can be used for advantageously fixing the roof board by inserting a projecting edge formed on the roof board.

[Effect of idea]

The eaves connection structure of this invention cleverly and easily connects a square cross-section support and an oddly shaped eave with the same square cross section using a connection fitting made of a pair of plates bent at right angles. This method is superior in that it can be easily connected without reducing the strength of the pillars or eaves, compared to the conventional connection method in which the ends of the eaves are inserted and fixed into the notched holes formed in the pillars. It is something.

In particular, in this invention, the bent edges of the eave are engaged with and fixed in the notches of the connecting fittings, so there is no risk of rattling after the connecting fittings.

In addition, fixing nuts are used for the main parts, and it can be assembled by tightening the bolts and dismantled by simply removing the bolts, making it safe and extremely quick to assemble and disassemble. - It is convenient to apply to structures, especially simple structures such as sunrooms and extension rooms, and this invention has great practical value in these respects.
