Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a joint cover for buildings that covers joints between adjacent buildings, and in particular connects a thin cover body to a connecting body that is attached to the building. This invention relates to a joint cover for buildings with an improved structure.

[Prior Art] This type of building joint cover is attached to adjacent buildings via connecting bodies on both sides of the cover body. In this case, the conventional structure for fixing both sides of the cover body to the coupling body was to form a mounting groove in the coupling body, insert the cover body into the mounting groove, and tighten and fix the cover body with screws.

However, with this fixed structure, the cover body is generally made of a thin sheet of 0.1 to 0.3 mm, so it may be locally damaged due to the tightening force of the screws, or the building may be damaged due to earthquakes, storms, etc. There is a problem in that when the screws swing in opposite directions, they are locally subjected to tensile force, causing damage or falling out of the mounting groove.

[Purpose of the invention] The purpose of the invention is to maintain a secure mounting condition without the risk of the cover body being locally damaged by the tightening force or tensile force of the screws, or falling out of the mounting groove. Our goal is to provide joint covers for buildings.

[Summary of the invention] The present invention includes a mounting groove formed between mutually opposing wall surfaces of a connecting body, and a substantially V-shaped inner surface of one of the two wall surfaces forming the mounting groove. Alternatively, an arc-shaped recessed part and a screw hole formed in the other wall surface so as to face the lowest part of the recessed part, mounting parts formed on both sides of the cover body and inserted into the mounting groove, and the recessed part a pressing member that is formed in the same shape as the mounting portion and is inserted into the mounting groove from the opposite side of the recessed portion; and a screw that clamps and fixes the mounting portion between the pressing member and the concave portion by pressing at a portion corresponding to the pressing member.

[Example] An example of the present invention will be described below based on FIG. 1 and 2 are the first and second buildings,
These are close to each other, and a joint 3 is formed between them. Reference numerals 4 and 5 denote first and second mounting bodies formed by press molding of aluminum, for example, which have a flat plate shape elongated in the vertical direction, and are attached to the outer surfaces of the first and second buildings 1 and 2. It is arranged along the joint 3 and fixed with a bolt 6. A substantially C-shaped guide portion 7 is formed in the first and second mounting bodies 4 and 5 along the longitudinal direction thereof. 8 and 9 are vertically elongated first and second connecting bodies formed by extrusion molding of aluminum, for example, and have a substantially L-shaped cross section, and have a guide portion on one end thereof. A sliding portion 10 having a circular cross section is formed to fit into the sliding portion 7, and a mounting groove 11 that opens laterally is formed on the other end side. This mounting groove 11 is formed between wall surfaces 12 and 13 that face each other in the front and back, and one wall surface 1
A concave portion 14 having a substantially V-shape is formed on the inner surface of the second wall, and a screw hole 15 is formed on the other wall surface 13.
are formed intermittently at predetermined pitch intervals facing the lowest part of the concave portion 14. 16 is a cover body that is elongated in the vertical direction;
is made of an aluminum sheet of approximately 0.1 to 0.3 mm, and is formed into a bellows shape so that it can be expanded and contracted in the left and right directions, that is, in the width direction, and has approximately the same shape as the concave portion on both left and right sides. The F-shaped attachment portion 17 is curved. Reference numeral 18 denotes a pressing member elongated in the vertical direction. This pressing member 18 is formed by extrusion molding of aluminum, for example, and has a substantially U-shaped cross section that is the same shape as the recessed portion 14.

Therefore, the mounting portions 17 on both sides of the cover body 16
are inserted into the mounting grooves 11 of the first and second connecting bodies 8 and 9, respectively, and the pressing member 18 is also inserted into the mounting groove 11 and attached to the mounting portion 17 of the cover body 16.
from the opposite side of the recessed portion 14. Then, the screw 19 is screwed into the screw hole 15 of the wall surface 13 of the mounting groove 11, and the pressing member 18 is tightened by this screw 19.
The cover body 16 is clamped and fixed between the pressing member 18 and the concave portion 14 by pressing at a portion corresponding to the lowest portion of the concave portion 14, that is, the lowest portion of the substantially chevron-shaped concave side (top surface in the figure). are doing. In this way, the sliding portions 10 of the first and second connecting bodies 8 and 9 attached to both sides of the cover body 16 are
The second mounting bodies 4 and 5 are fitted into and connected to each other so as to be vertically movable by being inserted into the guide portions 7 of the second mounting bodies 4 and 5.

In the above configuration, when both buildings 1 and 2 shake vertically and horizontally due to an earthquake or a strong wind, the sliding portions 10 of the first and second connecting bodies 8 and 9 move between the first and second connecting bodies 8 and 9.
While sliding in the vertical direction along the guide portions 7 of 4 and 5, the cover main body 16 expands and contracts in the left-right direction, thereby absorbing the relative movement of the buildings 1 and 2 in the vertical and horizontal directions.

According to the above configuration, since substantially the entire vertical direction of the mounting portions 17 on both sides of the cover body 16 is clamped and fixed between the recessed portion 14 and the pressing member 18, the screws are directly pressed into the mounting portions of the cover body. Unlike in the past, when the cover body 16 is locally damaged by the tightening force of the screws 19, or when the buildings 1 and 2 are shaken vertically and horizontally, a large tensile force is applied locally. There is no fear that the cover body will be damaged, and it can withstand long-term use. In addition, the mounting portion 17 of the cover body 16 is sandwiched between the substantially V-shaped concave portion 14 and the pressing member 18, and the screw 19 is attached to the substantially chevron-shaped concave side of the pressing member 18. Since the pressure is applied at the lowest part of the surface, the tightening force of the screw 19 is also applied to both left and right sides of the lowest part of the pressing member 18.
As a result, the mounting portion 17 can be pressed with the entire width direction of the pressing member 18 to more securely sandwich it between the recessed portion 14, and the mounting portion 17 is generally not subjected to tensile force. will not come out from between them, and the function of covering the joint 3 will not be impaired.

In the above embodiment, the mounting portion 17 of the cover body 16 is formed in advance in a substantially V-shape, but the cover body 1
Since 6 is thin, it is bent into a substantially V-shape when the mounting portion 17 is press-fixed between the wall surface 12 and the pressing member 18, so there is no need to form the mounting portion 6 into a substantially V-shape in advance.

Further, the guide portions 7 of the first and second mounting bodies 4 and 5 are formed in a substantially C shape, and the first and second sliding portions 1
0 is formed to have a circular cross section, but the shape is not limited to this, and may be any shape as shown in FIGS. First, as shown in FIG. 4, it may be formed into a circular arc shape, for example, a substantially C-shape. Further, in the above embodiment, both the first and second connecting bodies 8 and 9 are attached to the first and second attachment bodies 4 and 5 so as to be vertically slidable, but one of the connecting bodies is attached to the attachment body. If it is attached so that it can slide up and down, the other connecting body may be fixed directly to the building.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with various modifications without departing from the gist thereof.

[Effects of the invention] As explained above, the present invention includes a mounting portion of the cover main body that is formed by forming a substantially chevron-shaped or arc-shaped recess formed on one inner surface of the mounting groove and a pressing member having the same shape as the recess. Since the cover is clamped and fixed with a screw in between, and the screw is tightened at the lowest part of the approximately chevron-shaped or arc-shaped concave surface, the cover body receives the tightening force of the screw locally. Moreover, the mounting part is sandwiched between the approximately chevron-shaped or arc-shaped concave part and the pressing member, and the tightening force of the screw is applied to the entire width direction of the pressing member. Since the mounting part can be pressed in the entire width direction of the pressing member, there is no risk of the cover body being locally damaged by tensile force when the building swings, or falling off from the mounting groove, ensuring reliable installation. It has the excellent effect of being able to maintain the condition for a long period of time.
