Description

Description: TECHNICAL FIELD The present invention relates to a zipper gasket in which a glass plate, an outer wall plate and the like are connected in a building and can be connected to a building girder material.

[Conventional technology]

2. Description of the Related Art Conventionally, in a factory, a warehouse, a gymnasium, and the like, a part of a roof is opened, and a daylighting plate made of glass or synthetic resin is incorporated in the opening to form a skylight.

The plurality of daylighting plates are connected in a planar manner with their end faces abutting, but a long aluminum drawn material is used as the connecting member. This connecting member has a complicated structure and a high unit price in order to securely connect the daylighting plates to each other, and to make the rain finishing process sufficient. Moreover, the construction work required skill.

In recent years, when constructing a skylight with a daylighting plate, a gasket made of an elastic material such as rubber has been used instead of the above-described metal continuous member.

In recent years, buildings with walls made entirely of glass have been constructed, but gaskets have been used to bond this glass, and furthermore, glass plates and outer wall plates or outer wall plates have been connected in a plane, Gaskets are also used when building walls.

Gaskets are provided in various shapes and structures depending on the purpose and location of use, but there is a gasket that connects the gasket and the building girder material on the indoor side via a connecting member to support and reinforce. .

FIG. 3 shows an example of a gasket which can be connected to a connecting member. A known document is shown in FIG. 3 of Japanese Utility Model Publication No. 63-15453.

In this gasket 1, a pair of holding pieces 2 and 3 are formed on both sides in the longitudinal direction of a long rod-shaped body made of an elastic material such as rubber. . Clamping piece 2,
A solid groove 5 is formed in the plane portion on the two sides along the length direction, and a zipper 6 is made detachable in this solid groove 5 and can be tightly inserted. A flat connecting groove 7 which is parallel to the fitting groove 4 and is flat is formed in the flat portion on the side of the holding pieces 3 and 3 along the length direction.

The connecting member 8 attached to the gasket 1 is a long member parallel to the gasket 1, and generally uses an H-shaped steel.

A plate body 9 such as a glass plate or an outer wall plate is fitted with its longitudinal end into the fitting groove 4. In this case, the zipper 6 is removed from the fixing groove 5 and the fitting groove 4 is expanded. Plate 9
By inserting the zipper 6 into the fixing groove 5, the holding piece 2 is pressed against the plate body 9 to reinforce the holding force.

[Problems to be solved by the invention]

Since the width H of the connecting groove 7 of the gasket 1 is limited, the rib of the H-shaped steel cannot be inserted as it is, and the rib 8a on one side must be adjusted to the length of the space H.

Conventionally, both sides of the rib 8a in the longitudinal direction are used by cutting with a cutter in accordance with the length interval H of the connecting groove 7.

However, the shape of the entire H-section steel may be distorted due to cutter heat generated when cutting both sides of the rib 8a, so that the entire shape cannot be specified and cannot be attached to the gasket 1. . If the rib 8a is forcibly inserted into the connection groove 7, the gasket 1 itself is distorted,
A gap is formed between the fitting groove 4 and the plate body 9 to hinder the holding of the plate body 9.

Even if the connecting member 8 is not distorted, burrs are generated on the cut surface during cutting. If the burrs are put into the connecting groove 7 without processing, the burrs may damage the inside of the connecting groove 7, This causes the strength of the entire gasket 1 to be weakened.

Further, since the insertion opening 10 communicating with the connecting groove 7 is narrow, it is extremely difficult to fit the rib 8a through the insertion opening 10.

In addition, since the shape of the connecting member 8 is specified as the H-shaped steel, the structure of the building girder to which the connecting member 8 is to be connected on the indoor side is restricted, which hinders the development of a new technology for the building girder.

In view of the above-mentioned various problems of the conventional gasket and the connecting member, the present invention eliminates the connecting groove 7 and integrally connects the locking member along the holding member on the opposite side to the holding member that makes the zipper detachable. It is an object of the present invention to provide a zipper gasket which is continuously provided and in which a locking projection of a connecting member can be fitted into a locking step formed between a holding piece and a step of a locking member.

[Means for solving the problem]

In order to achieve this object, the gasket of the present invention includes a plate body such as a glass plate and an outer wall plate between a pair of sandwiching pieces 12 and 13 formed on both longitudinal sides of a long body made of an elastic material such as rubber. In a gasket that is fitted and has a zipper 16 detachably attached to the flat portion of one of the holding pieces 12, the holding pieces 13, 13 on the opposite side to the holding piece 12 having the zipper 16 are aligned in the length direction of the central portion of the outer plane. The locking member 17 is integrally and continuously provided, and the holding recess 13 is formed between the holding steps 13, 13 and the locking step 18 between the holding member 17, and the holding piece 13 facing the locking recess 19, 13 has a gasket 11 having a recess 13a formed in the entire length thereof, and a locking projection 22 formed on one side in the length direction of a long metal plate, and is connected in the opposite direction to the locking projection 22 on the other side. A connecting member 21 is formed to form a pair 23 with left and right locking projections 22 facing each other, and each locking projection 22 is fitted into a locking recess 19 respectively. There as possible is.

〔Example〕

Hereinafter, an embodiment of the present invention will be described in detail along with the operation with reference to the drawings.

FIG. 1 shows a gasket main body according to the present invention. This gasket main body is composed of a gasket 11 and a connecting member 21.

As shown in detail in FIG. 2, the gasket 11 is provided on both sides in the length direction of a long rod-shaped body made of an elastic material such as rubber.
A pair of holding pieces 12 and 13 are formed symmetrically in the vertical direction, and holding pieces
The space between 12 and 13 is defined as a fitting groove 14 and one of the holding pieces 12 and 12
A zipper 16 is detachably provided in a fixing groove 15 formed along the length direction in the plane portion of the zipper. Then, the locking members 17 having the zipper 16 are integrally connected with the locking members 17 along the length direction of the central portion of the outer plane of the holding pieces 13 and 13 on the opposite side to the holding pieces 13 and 12,

The connecting member 21 closely fits the longitudinal ends of the plate 20 such as a glass plate or an outer wall plate between the fitting grooves 14 on both sides, and the plate 20
The flat gasket 11 is for connecting the fixed gasket 11 to a building girder material (not shown), and a U-shaped locking projection 22 is horizontally arranged on one side in the length direction of a long metal plate. On the other side in the length direction of the metal plate, a connecting portion 23 that can be connected to a building girder material (not shown) is horizontally bent and formed in a direction opposite to the locking protrusion 22. It is. Such a shape is integrally formed by roll homing.

A pair of connecting members 21 are used symmetrically with the locking projections 22 facing each other, and the center portion can be connected and fixed using bolts, nuts and the like.

As shown in FIG. 1, the locking recesses 19 on both sides of the gasket 11
When the locking projections 22 of the connecting members 21 are closely fitted into each other, and the pair of connecting members 21 are connected and fixed to each other, the locking projections 22 are pressed into the locking recesses 19 by metal elasticity, and The stop projection 22 is hooked on the locking step 18. Therefore, the connecting member
Even if a pulling action is applied to the connecting portion 23 in the direction of the connecting portion 23, the locking projection 22 does not come out of the locking concave portion 19, and the connection state between the gasket 1 and the connecting member 21 becomes strong.

The connecting member 21 shown in FIG. 1 is an example. If the connecting member 21 has a locking projection 22 which can be tightly fitted in the locking recess 19 and can be connected, the other shapes are the same as those shown in the drawing. Not specified.

〔The invention's effect〕
