Description

[Detailed explanation of the invention] This invention relates to eaves installed above openings in buildings, and the purpose of this invention is to enable easy and rational installation, especially for buildings whose walls are made of lightweight concrete plates. This is what I did.

Conventionally, there have been various structures for eaves installed above openings in buildings, such as windows and doorways. There was still little to see about the eaves, which were made of light concrete and could be easily attached to walls.

In the case of the lightweight concrete plate, this is because of its strength.
There are restrictions such as the need to pass the mounting bolts through the concrete plate, and reinforcing reinforcing bars are buried within the lightweight concrete plate, so the face must be avoided when penetrating the bolts. it is conceivable that.

Furthermore, since the rear surface of the conventional eaves is attached to the wall surface, there is a problem in that it is difficult to completely protect the face from rain.

However, this idea involves forming a through hole along the entire length in the middle part of the rear wall that is attached to the wall of the building in the wall that forms the eaves, and attaching a bolt retaining plate to the inside of the rear wall. So,
The eaves can be attached by simply drilling holes in the predetermined portions of the bolt retaining plate (positions away from the reinforcing bars embedded in the lightweight concrete plate), which solves the conventional problems and makes it possible to install the eaves. This allows for easy and streamlined installation.

In addition, since a treated edge with a tabular cross section is formed on the wall surface abutting portion, the treated edge is fitted into a groove provided in the wall surface, thereby making it possible to reliably cover the rain.

That is, to explain this invention with reference to an embodiment, rectangular side plates 2 with raised rear portions are placed on both sides of a bottom plate 1 bent in a cross-sectional shape.
2 is fixed, and a rear plate 3 is fixed between the rear upper sides of the side plates 2, 2 to form a metal box body 4 with an open top.
and a metal roof body 6 that closes the opening 5 formed at the top.
and make up the eaves.

The rear rising wall 1a of the bottom plate 1 is lower than the front rising wall 1b, and has an inverted cross-section, and the lower edge of the rear plate 3 has an inverted cross-section. A rectangular through hole 7 is formed between the rear plate 3 and the rear wall 3 over almost the entire length of the rear wall of the box body 4.

On the inner side of the rear wall where the through hole 7 is formed, there is a bolt hooking plate 8 that is approximately equal to the entire length of the box body 4 and has a size that closes the through hole 7.
The locking plate 8 is provided with elongated holes 9, 9 for bolt insertion at predetermined portions (for example, three locations).

The bolt retaining plate 8 has a U-shaped cross section, and is designed to exhibit elasticity in conjunction with the rising wall 1a and the protruding edge of the rear plate 3.

The box body 4 and the roof body 6 are engaged by forming a winding part 10 formed on the edge of the box body 4 and a winding part 1 formed on the edge of the roof body 6.
1 and install it.

That is, the rising wall 1b of the bottom plate 1 and the upper edges of the side plates 2, which constitute the box body 4, are each wound outward to form a wound portion 10, and the front edge and side edges of the roof body 6 are Winding part 1
The winding part 11 is made by winding the winding part 11 so that it can be fitted on the outside of the winding.

A screw hole 12 is provided on the upper surface of the winding portion 10 of the side plates 2, 2, and a screw 14 is inserted through the screw hole 13 on the side of the roof body 6.
If you screw them on, the two will engage as one.

The rear edge of the roof body 6 is bent to have a T-shaped cross section to form a treated edge 15 for rain protection.

To attach the eaves of the above embodiment to the wall surface 16 (autoclave light concrete) of the building, after the rear wall (rising wall 1a and rear plate 3) of the box body 4 is brought into contact with the wall surface 16 and fixed, the box body 4 is The roof body 6 is attached to the roof body 6.

The box body 4 is fixed to the wall surface 1 by drilling a through hole 18 in the wall surface 16 for inserting a bolt 17, and attaching the bolt 17 to the wall surface 16 through the bolt 17 inserted into the through hole 18 and a nut 19 screwed thereto.
6 and the bolt retaining plate 8 are sandwiched together.

The drilling position of the through hole 18 is appropriately selected so as not to overlap with the reinforcing bars buried in the wall surface.
Since the elongated hole 9 is drilled in the hole 9, after the through hole 18 is drilled,
Clamping work using bolts 17 and nuts 19 can be performed immediately.

Once the box body 4 is fixed, the roof body 6 is attached to the box body and the screws 14 and 14 are screwed to integrate the two.

The treated edge 15 formed on the rear edge of the roof body 6 has a groove 2 in the wall surface 16.
0 is inserted into the groove 20, and the gap is filled with caulking material 21 to cover the rain.

In the figure, 22 is a window. In the above embodiment, the bolt retaining plate 8 was made to have a length approximately equal to the entire length of the box body 4, and long holes 9, 9 were drilled for the insertion of the bolts 17. Multiple pieces (the total length must be shorter than the total length of the box).

), a circular hole may be bored in each for bolt insertion, and the bolt retaining plate may be moved to match the through hole 18 provided in the wall surface 16.

That is, according to this invention, the eaves are formed by the box body and the roof body that engages with the box body, and a through hole is formed in the rear wall of the box body, and a bolt hook plate is attached to the inside of the rear wall, so that the inside It can be easily and rationally installed even on walls made of lightweight concrete plates with embedded reinforcing bars.

In addition, since a treated edge with a J-shaped cross section was formed on the rear edge of the roof body,
By providing a groove in the wall surface and inserting the treated edge into the core part, there is an effect that reliable rain cover treatment can be performed.

Handling safety can be improved by forming a winding part on the edge of the opening of the box body and also forming a winding part on the edge of the roof body so that the two can fit together. At the same time, it has the effect of ensuring the engagement between the two and creating a solid eaves.
