Abstract

PROBLEM TO BE SOLVED: To provide a gasket capable of executing insertion mounting work with ease and high accuracy as well. SOLUTION: An exterior wall joint gasket 10 is provided with a skeleton 11 which is in a relatively continuous length and whose cross section is substantially rectangular-shaped, a first water stop lip 12, a second water stop lip 13 projectingly provided along both side surface of the skeleton from the upper part to the lower part, a stopper 16 and a guide lip 14. The guide lip 14 and the stopper 16 are provided with a clearance (j) which allows a maximum insertion depth (d) with the whole gasket 10 for an exterior wall joint 3. Due to this construction, when the guide lip 14 which comes in contact with the top of the frame member 2 is elastically deformed and inserted until the clearance with the stopper 16 becomes zero, it is possible to prevent automatic insertion at that maximum insertion depth (d), and maintain an excellent outside appearance of the joint.

The guide lip portion and the stopper are vertically opposed to each other with a gap sufficient to allow a maximum insertion depth of the entire gasket for the outer wall joint portion with respect to the outer wall joint portion. Achieved by gasket.

Further, the object of the present invention is attained by a gasket for an outer wall joint, wherein the guide lip has a total width wider than a total width of the outer wall joint and a frame gap. You.

Further, the object of the present invention is that the first water-stop lip portion and the second water-stop lip portion are formed by bridging opposite spaces with a reinforcing rib portion. Achieved by a gasket.

A gasket for an outer wall joint according to the present invention has a relatively long skeleton having a substantially rectangular cross section, and a first water stopping portion sequentially projecting from above and below both side surfaces of the skeleton. An outer wall joint gasket comprising a lip portion, a second water stop lip portion, a stopper, and a guide lip portion, wherein the guide lip portion and the stopper have a maximum relative to the outer wall joint portion of the entire outer wall joint gasket. Since the guide lip portion abuts on the upper surface of the frame member, since the guide lip portion is vertically opposed with a gap enough to allow the insertion depth,
When the gap between the stopper and the stopper is elastically deformed and inserted until the gap becomes zero, the insertion is automatically prevented at the maximum insertion depth, and an excellent joint appearance can be maintained.

Further, in the gasket for an outer wall joint according to the present invention, the guide lip has a total width set to be wider than a whole width of the outer wall joint and a frame gap.
The guide lip portion is reliably elastically deformed by the outer wall joint and the frame gap, and automatic insertion prevention at the maximum insertion depth is guaranteed.

Further, in the gasket for an outer wall joint according to the present invention, since the first water-stop lip portion and the second water-stop lip portion are formed by bridging opposing spaces by a reinforcing rib portion, the guide lip is provided. Part is at the maximum insertion depth,
Even if the function as the water stop lip is lost, only the first water stop lip and the second water stop lip, which have increased bending rigidity by the reinforcing ribs, can provide a sufficient water stop effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the gasket for an outer wall joint according to the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 shows a gasket 10 for jointing an outer wall according to the present invention.
2 is a cross-sectional view of a main part showing a state where the gasket 10 is inserted into the outer wall joint part 3, and FIG. 2 is a cross-sectional view showing a main part of the gasket 10 for an outer wall joint part of the present invention before insertion. The outer wall joint 3
The gasket 10 for an outer wall joint portion of the present invention before insertion into
As is apparent from FIG. 1, a relatively long skeleton portion 11 having a substantially rectangular cross section, a first water stop lip portion 12 sequentially protruding from above and below both side surfaces of the skeleton portion 11, 2. It comprises a water stop lip portion 13, a stopper 16, and a guide lip portion 14.

When the gasket 10 for an outer wall joint according to the present invention configured as described above is inserted into the outer wall joint 3, the guide lip 14 first contacts the inner side surface of the outer wall joint 3. While being elastically deformed, it advances toward the frame gap G in such a manner as to guide the subsequent first water-stop lip portion 12, second water-stop lip portion 13, and stopper 16. In addition,
The guide lip section 14 and the stopper 16 are vertically opposed to each other with a gap j sufficient to allow a maximum insertion depth d of the entire outer wall joint gasket 10 to the outer wall joint section 3 before insertion. Therefore, when the guide lip portion 14 comes into contact with the upper surface of the frame member 2, as shown in FIG.
The guide lip portion 14 starts elastically deforming, and the stopper
It is inserted until the gap j with 16 becomes zero.

The amount of change in the gap j due to the elastic deformation of the guide lip portion 14 is appropriately determined in consideration of the inclination angle of the guide lip portion 14 and the shape of the stopper 16. In consideration of its stopping function, the stopper 16 preferably has a triangular cross section with increased bending rigidity.

The entire width of the guide lip portion 14 is set to be wider than the entire width of the outer wall joint portion 3 and the frame gap G. For example, the entire width of the outer wall joint portion 3 is equal to that of the outer wall joint portion 3. When the inner surface is extended by C-chamfering or R-chamfering at the corners, contact of the tip portion with the inner surface of the outer wall joint portion 3 is not guaranteed, but the desired relationship with the frame gap G is maintained. Is achieved.

The tip of the guide lip portion 14 is in a non-contact state as described above, and the remaining first water stop lip portion is provided.
When there is anxiety about the water stopping action of the 12 and the second water stopping lip 13, by bridging the reinforcing rib 15 in the space facing the first water stopping lip 12 and the second water stopping lip 13, The bending rigidity of the two water stopping lip portions 12 and 13 is increased to ensure a sufficient water stopping effect.
