DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a wall-like structure in which at least one of a pair of plate-like building materials adjacent to each other via a joint is installed so as to be openable and closable along its thickness direction. A joint sealing structure in which an elastic gasket is provided in the joint portion of the body over the entire length or almost the entire length in the joint longitudinal direction, and at least one of the pair of adjacent plate-like building materials is in the thickness direction. The present invention relates to a joint seal forming method for sealing an joint between the two plate-like building materials with an elastic seal member in a mounting structure installed so as to be freely opened and closed along the line.

[0002]

2. Description of the Related Art Conventionally, when the above-mentioned plate-like building material is a decorative plate or a glass plate, in order to improve the aesthetics of a wall-like body formed by juxtaposing the plate-like building materials, particularly at joints. As shown in FIG. 9, this type of joint sealing structure includes an elastic gasket 2 attached to an edge of both plate-like building materials 1 adjacent to each other at an joint M.
In some cases, the elastic gaskets 25 are adhered to each other and pressed against each other while being elastically deformed at the joints M (pressed along the direction in which both plate-like building materials 1 face the end surfaces). Further, as described above, this type of joint seal forming method has been practiced by bonding the elastic gaskets 25 separately to the edge portions of the two plate-shaped building materials 1.

[0003]

In view of the fact that the width of the joint may have an error depending on the manner of installation of each plate-like building material, or that the elastic gasket itself has a dimensional error, the above-described conventional technique is considered. According to the joint seal structure and the joint seal forming method, in order to obtain a good joint sealing effect, the elastic gasket 25 is previously formed to have a large size so that the elastic gaskets 25 are strongly pressed against each other. In advance, it is necessary to install the joint so as to be in an elastically deformed state at the joint portion M. However, the deformation of the elastic gasket 25 due to the pressing increases,
There is a danger that the aesthetic part is deteriorated by protruding from the joint M. Further, each time one of the plate-like building materials 1 is opened and closed along the thickness direction, the two elastic gaskets 25 are required.
As a result, the gasket 25 is greatly consumed, and the opening / closing operation acts on the bonding portion between the plate-like building material 1 and the gasket 25 in a direction in which the gasket 25 is peeled off. There is a problem that tends to decrease. Further, since a frictional force acts between the two elastic gaskets 25, a strong operation force is required, and there is a problem that it is difficult to open and close, and a large opening and closing angle cannot be obtained.

Accordingly, an object of the present invention is to solve the above-mentioned problems, and to provide a joint sealing technique capable of ensuring good waterproofness and aesthetics of joints while smoothly opening and closing a plate-like building material. There.

[0005]

[Means for Solving the Problems]

[Structure] As shown in FIG. 6, a characteristic structure of the invention according to claim 1 is a pair of plate-like building materials 1 adjacent to each other via joints M.
At least one of the plate-like building materials 1 is provided with an elastic gasket 10 over the entire length or substantially the entire length in the joint longitudinal direction at the joint M in the wall-shaped body W installed so as to be openable and closable along its thickness direction. In a certain joint seal structure,
A first receiving portion 11 capable of receiving a back surface portion of the two plate-shaped building materials 1 at an edge portion on the joint portion M side of the both plate-shaped building materials 1 over the entire length or substantially the entire length in the joint length direction. The elastic gasket 10 is separately provided with a mounting portion 12 for supporting the gasket 10 on the fixed side between the first receiving portions 11.

A feature of the invention according to claim 2 is that, as illustrated in FIG. 6, an elastic ridge projecting toward the plate-like building material 1 is provided on the first receiving portion 11 over the entire length in the longitudinal direction of the joint. There is a place.

As shown in FIG. 6, the second embodiment of the present invention is characterized in that the second receiving portion 13 which can be brought into close contact with the end face of the two plate-like building materials 1 on the joint M side is provided. The gasket 10 is provided between the first receiving portions 11.

A feature of the invention according to claim 4 is that, as exemplified in FIG. 7, at least one plate-like building material 1 of a pair of adjacent plate-like building materials 1 can be opened and closed along its thickness direction. In sealing the joint M between the two plate-like building materials 1 in the installed mounting structure with the elastic seal member 17,
In advance, the elastic seal member 17 is brought into close contact with the
Elastic gasket having a sheet Lumpur receiving 18 to reduce the joints waterproofing
The plate-like building material 1 and the release material 1 are provided in a state where the release material 19 is disposed on the seal receiving surface of the seal receiving portion 18 in a state in which the joint 10 is provided over the entire length or almost the entire length of the joint portion M.
9 is filled with a curable sealing paste 17a, and after the elastic sealing member 17 is formed by curing the sealing paste 17a, the release material 19 is removed.

Note that, as described above, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration shown in the accompanying drawings.

According to the feature of the first aspect of the present invention, the first and second receiving portions can separately receive and seal the rear edge portions of the pair of plate-like building materials. It is possible to exhibit a good sealing effect while preventing the gasket from being deformed and protruding, and it is possible to improve the appearance and aesthetics of the wall-shaped body. In addition, since the receiving direction of the plate-like building material at the first receiving portion is along the opening / closing direction of the plate-like building material, it is unlikely to hinder the opening / closing operation of the plate-like building material, and can be operated smoothly. And
As in the related art, it is possible to reduce the friction between the gaskets and wear, and it is possible to improve the durability of the gasket. In addition, since the mounting portion is provided between the first receiving portions, the gasket is supported by the mounting portion, and the pressing force from the two plate-shaped building materials is separately applied to the first receiving portions on both sides thereof. It acts and becomes a stable stress supporting state (for example, the stress state of Yajirobei). That is, in a state where both plate-like building materials are pressed against the first receiving portion (the one plate-like building material is in a closed state), the one plate-like building material (or the other plate-like building material) is one of the first plate-like building materials. The force for pressing one receiving portion (or the other first receiving portion) is such that the other plate-like building material (or one plate-like building material) and the other first receiving portion (or one Reflected in the pressing force with the first receiving part)
It is possible to maintain a high sealing effect between the two plate-shaped building materials and the elastic gasket in a stable stress state.

According to the characteristic configuration of the second aspect of the invention, in addition to achieving the functions and effects of the first aspect of the invention, it is possible to elastically receive the back surface of the plate-like building material by the elastic ridge. As a result, the gasket familiarity with the plate-like building material becomes better, and the movement of the plate-like building material (for example, movement or vibration caused by wind pressure) becomes better, and the sealing performance of the joint can be further improved. Become.

According to the characteristic configuration of the third aspect of the present invention, while the operation and effect of the first or second aspect of the invention can be achieved, in addition to the sealing action of the joint in the first receiving portion,
The sealing effect of the second receiving portion can also be expected, and the sealing performance of the joint portion can be further improved.

According to the characteristic feature of the fourth aspect of the present invention, the gap between the seal receiving portion and the plate-like building material is simply filled with the sealing paste and cured, and the elastic sealing member adapted to the gap dimension can be easily formed. By removing the release material provided on the seal receiving portion, the elastic seal member integrated with the plate-like building material and the seal receiving portion can be detachably contacted. Become. In general, the size of joints is often slightly different due to dimensional errors and mounting errors of plate-like building materials. However, according to the method of the present invention, a seal having a shape that surely matches a joint that differs from place to place. The member can be easily formed, and as a result, the joint seal can be formed in a state where the opposing surfaces of the seal receiving portion and the elastic seal member are securely pressed. Further, since the seal receiving portion and the elastic seal member can be in close contact with each other, a sufficient sealing effect can be exerted without forcibly pressing both of them. By this operation, it is possible to prevent the gaskets from rubbing each other as in the related art during opening and closing operations of the plate-like building material, thereby making it possible to smoothly open and close the plate-like building material. Furthermore, in order to absorb a delicate dimensional error of the joint portion, the seal member is apt to be formed in advance by a method of forming the seal member in a relatively large size (by press-fitting compression deformation in a sealed state). It is also possible to prevent the joint portion from feeling unsightly or to require extra material cost, and it is possible to economically secure good waterproofness and aesthetics of the joint portion.

In addition, the glass panel 1 corresponding to the smoke exhaust window has a columnar mounting bracket 7 for mounting the hinge member 5 at a plurality of locations spaced apart in the lateral direction of the upper edge.
Is mounted in a state of protruding to the back side. And
A column-shaped mounting bracket (corresponding to a fixed-side fixing member) 8 is also mounted on the corresponding portion of the glass panel 1 adjacent to the glass panel 1 so as to protrude to the back side. A hinge member 5 is provided over 8 (see FIG. 1). Incidentally, the hinge member 5 and the mounting bracket 7 provided on the openable and closable glass panel 1 are rigidly and integrally attached, and the hinge member 5 and the mounting bracket 8 of the glass panel 1 adjacent to the upper side are connected to each other. , Is mounted so as to be relatively swingable around a hinge portion H provided with a hinge rotation axis P arranged horizontally along the glass surface (see FIG. 5).

The hinge member 5 is swingable around the hinge rotation axis P and the glass curtain wall W
A rocking arm 9 which is curved is provided on the surface side of the device. Since the swing arm 9 is curved, the lower edge of the upper glass panel 1 when the glass panel 1 is swung in the opening direction around the hinge rotation axis P,
It becomes possible to receive in the said bending part, and it becomes possible to swing at a larger angle. The position of the hinge portion H is set on the back side of the upper glass panel 1 (specifically, above the upper edge of the openable and closable glass panel 1), so that the glass panel 1 swings. It is possible to secure a long rotating radius when moving, and make the angle in the opening and closing direction as close as possible to the perpendicular direction of the curtain wall surface, so that a large compressive force or shear force acts on the elastic joint M on the outer peripheral portion of the glass panel 1. Can be prevented. The detailed structure of the hinge portion H is a hinge shaft 9a formed on the swing arm portion 9 and a hinge shaft 9a formed on the mounting bracket 8 and provided with respect to the hinge shaft 9a.
And a hook-shaped portion 8a which can be engaged along the radial direction. As shown in FIG. 5, the hook portion 8a has a narrow entrance portion. on the other hand,
The hinge shaft 9a has an outer peripheral cutout 9b which can be engaged with the narrow width entrance only in a specific posture.
Is formed. Therefore, when the openable and closable glass panel 1 is attached to the mounting bracket 8, the posture in which the outer peripheral cutout 9b of the hinge shaft 9a can be engaged with the hook-shaped portion 8a (in the present embodiment, the outer peripheral cutout 9b).
It can be implemented by a simple operation of simply engaging the hook-shaped portion 8a inside by setting the offset flat surface formed into a vertical arrangement, and in the state where both are engaged, the hinge rotation axis center (the axis of the hinge axis). Relative rotation about the core (P). And, unless the posture of both becomes the relative posture at the time of engagement,
The hinge shaft 9a can be prevented from coming off from the hook-shaped portion 8a. The hook-shaped portion 8a and the outer peripheral cutout 9b constitute a retaining means U.

Next, the elastic joint M will be described. The elastic joint M is provided with an elastic gasket 10 extending over the entire length or substantially the entire length in the joint longitudinal direction. The elastic gasket 10 is a long member made of rubber.
As shown in the figure, at the edge of the both glass panels 1 on the joint portion M side, a first receiving portion capable of receiving the back surface portions of the two glass panels 1 in a tight state over the entire length or substantially the entire length in the joint length direction. Parts 11 are provided separately, and a mounting part 12 for supporting the gasket 10 on the fixed side is provided on the back side between the two first receiving parts 11.
A second receiving portion 13 which can freely contact the end surface of the joint portion M side of the joint member over the entire length or substantially the entire length in the joint longitudinal direction.
Are separately provided on the surface side between the first receiving portions 11. The first receiving portion 11 is provided with an elastic ridge 11a protruding in a fin shape on the glass panel 1 side over the entire length in the joint longitudinal direction, and is pressed against the glass panel 1 (or the glass panel is pressed). This allows the elastic ridges 11a to be elastically deformed and easily conformed to the glass panel, and to improve the water stoppage. The mounting portion 12 is formed by a longitudinal groove formed on the back side of the gasket 10. A groove of the mounting portion 12 is mounted on a protruding portion 14a of a gasket holding metal member 14 fixed vertically and horizontally across the mounting metal members 4 of the glass panel 1. The second receiving part 1
3 are formed on both slopes of a mountain-shaped ridge 13a provided along the longitudinal direction of the main body of the gasket 10, and when the glass panel 1 is in the closed state, the end face of the glass panel is pressed and the seal is pressed. It is possible to do. Further, since the protruding ridge 13a is formed in a mountain shape as described above, for example, there is a dimensional error of the glass panel or a mounting error of the glass panel, so that the position of the edge of the glass panel is shifted to the joint center. Even in the case where the glass panel is displaced closer, the glass panel edge can be received on the mountain-shaped slope with the opening and closing of the glass panel, and the displacement is absorbed by the elastic deformation of the protruding ridge 13a. As a result, an expected sealing effect can be secured. Further, since the hollow portion is formed in the protruding ridge portion 13a, it is possible to smoothly elastically deform with respect to an external force, and when the glass panel edge is pressed, it is smoothly elastically deformed. The close contact makes it possible to exhibit a predetermined sealing effect.

Next, the opening / closing mechanism D of the glass panel 1 will be described. An air cylinder 15 for urging the glass panel 1 (an urging means using a gas damper or a spring is also possible), and the glass panel 1 (See FIGS. 2 and 3), and the glass panel 1 is provided with the air cylinder 15.
And the wire winder 16 winds the wire 16a and tightens it with a force exceeding the air cylinder 15 opening force to close the smoke exhaust window of the glass panel 1. It becomes possible. Then, by feeding out the wire 16a, it becomes possible to open the smoke exhaust window of the glass panel 1 by the action of the urging force of the air cylinder 15. The air cylinder 15 is used to open and close the glass panel 1.
One end is connected to the lower part of both side edges of the wall, and the other end is connected to the wall supporting column 2. The wire winding means 1
Reference numeral 6 denotes a wire 16a having one end connected to the fixed side and the other end connected to the winding device 16b, a wire winding provided on the lower edge of the glass panel 1, and a corresponding portion on the fixed side.
