Description

[Detailed description of the invention] The present invention relates to a ready-made box-shaped eave constructed using metal plates, synthetic resin plates, etc., and in particular, the interior is made hollow by fixing a specified reinforcing plate to the back of the eaves body. The main body of the eaves is made into a structure that is strong against twisting and bending, and it is made to prevent distortion or deformation during construction when it is attached to a building, making installation work easily possible on site. It is something.

As is well known, there are two main types of box-shaped eaves.In the first type, a piece of wood is attached to the wall of the building in advance, and the main body of the eave, which is open at the back, is fitted into the water area of the building. (See Figures 1 and 2.) This method uses a sealed box-shaped eave that is not made of wood and is attached to the wall via a flange formed on the mounting surface. It is a method of striking.

The latter does not use arm wood, so the mounting strength is insufficient, and there is no resistance to the weight of the eaves itself or external forces.
Not worthy of a prize.

The arm-hydraulic type is the mainstream of box-type eaves because it provides sufficient installation strength, but it has the following inconveniences during installation and finishing, and improvements have been desired.

In other words, as shown in Figures 10 to 12, the structure of a conventional box-type eave using arm hydraulic power is such that the mounting surface of the eaves main body a to the building, in other words, the back surface of the eaves, is connected to the structure in which the arm wood is inserted. The top is completely open.

A reinforcing plate C is separately provided on this opening surface, but since this plate has a vertically long rectangular shape as shown in the figure, it has almost no resistance against distortion and is difficult to handle during transportation, storage, etc. At times, the entire eaves would twist diagonally, leaving a tendency to twist, or the eaves would concentrate on a portion of the eaves, causing buckling.

Also, as shown in Figure 12, even if the arms are inserted into the wood at both ends, the middle part may sag downward due to its own weight, or the eave ceiling d of the building wall and eaves may sag after installation. When finishing the contact area with mortar, the first
As shown in Figure 3A, the eaves tend to partially dent due to being pressed by the mortar, and as a result, the finished surface becomes wavy as shown in Figure 13B, causing problems in construction.

Here, the present invention is to install a back plate that serves as a brace in order to prevent the above-mentioned twisting and distortion from occurring at the back opening of the arm-hydraulic box-shaped eaves, and to adjust the width of this back plate. The height is set to be equal to or larger than the effective height of the opening surface, and is fixed to the opening surface.

To specifically explain the embodiment of the present invention shown in the drawings,
In Figs. 1 to 4, reference numeral 11 denotes an eaves having a roof plate 1 that slopes forward, an end plate 2, and an eaves top plate 3 that is bent at a right angle from the lower edge of the end plate 2 toward the rear. In the main body, vertical mounting pieces 4 and 5 are connected upwardly and downwardly to the rear edges of the roof plate 1 and the eaves top plate 3, respectively.

Note that in some cases, as shown in the drawing, the mounting piece 6 may be integrally extended and provided on the side surface thereof as well.

The above-mentioned eaves main body is pre-finished in a box shape as a replica in a factory, etc., and is attached to the pillars 12, studs 13, etc. that make up the walls of the building through the arms 7 that have been attached in advance. In this way, it is supported by being fitted into the tree from the outside.

Incidentally, since the eaves main body 11 described above is to be inserted into the arm tree 7, an opening surface 8 for receiving the arm tree 7 is provided on the back surface thereof.

The present invention provides a box-shaped eave 11 having the above configuration,
For the opening surface 8, a back plate 14 having a width equal to or larger than the effective height l of the opening surface is installed at least once per opening length A 90 cm. At the same time, the back plate may be fixed directly to the vertical mounting pieces 4 and 5 connected to the opening surface, or it may be fixed between the roof plate 1 and the eaves top plate 3 by means of fitting as described later. Make it.

The embodiment shown in FIGS. 1 to 4 has two slightly laterally elongated back plates 14,
This is an example in which the eaves main body 11 having an opening surface 8 with a length of 180 cm is attached at appropriate positions at approximately equal intervals, and in this case, both upper and lower ends of the back plate are fixed with rivets 15.

A reinforcing plate 16 having substantially the same shape as the arm wood is integrally attached to the front part of the back plate by welding, and this plate extends toward the inside of the eaves main body 11.

A gap is formed between the back plate 14 and the mounting piece 4 or 5 of the eaves main body 11, as shown by the symbol B in FIG. Consider making it easy to attach.

In other words, this type of eaves is attached by carpenters with nails or wood screws during on-site work, but since it would be difficult to do the work if the attachment part is made of two overlapping iron plates, in this invention, this attachment part is In order to construct the mounting plate from a single thin iron plate, the mounting pieces 4 and 5 are made to protrude outward from the upper and lower edges of the back plate 14, and the above-mentioned deviation B is formed in advance.

Figures 5 and 6 show another embodiment in which the back plate 17 is curved in a U-shape in cross section so that the back plate engages with the eaves roof plate 1 and the eaves top plate 3. This is the case.

In this case, there is no need to screw the back plate to the mounting pieces 4 or 5, and it is sufficient to fix it so that it does not move, so if a screw is used, one is sufficient, or it can be fixed with adhesive 18. It's okay.

Alternatively, as shown in FIG. 7, the engaging portions may be fixed with screws 19, or as shown in FIG. It may be caulked.

Incidentally, reference numeral 21 in FIG. 8 indicates a nail hole locally drilled in the back plate 20 so that the eaves main body can be nailed, and corresponds to the deviation B mentioned above.

FIG. 9 shows a third embodiment of the present invention, in which the back plate 22 is designed to cover the entire opening surface of the eaves main body, and the part indicated by reference numeral 23 in the figure is an armrest. This is a through hole for receiving the water.

Reference numeral 24 indicates a nail hole formed in the back plate portion so that the vertical mounting pieces 4 and 5 of the eaves can be directly nailed through this hole.

In the embodiment shown in FIG. 9 as well, the back plates 22 are fixed to the opening surfaces of the eaves main body over a wide area, so that the back plates serve as a reinforcement against the force that deforms the opening surfaces. As a result, it exhibits strong resistance against twisting and deformation.

As described above, the eaves of the present invention is provided on the back side and has a width equal to or larger than the effective height of the opening surface for inserting a tree. Since the plate is fixed partially or over the entire opening surface, this back plate acts as a brace against the opening surface of the eaves and prevents the opening surface from deforming.

Therefore, when the canopy itself is transported, stored, or installed on a building, even if the weight or external force acts on the canopy itself, the entire canopy will not be twisted or distorted, resulting in a robust structure. In addition to the body, the armwood tip also provides an eaves that takes full advantage of the advantages of a formal eave.

Furthermore, according to the present invention, since the back plate is fixed between the roof plate and the eave top plate on the mounting surface of the eaves, the eave top plate may sag or wave due to its own weight after installation. Therefore, even when mortar finishing is applied, it has an excellent practical effect in that it can eliminate defects such as unevenness of the finished surface.
