Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a joint joiner for closing a long narrow groove-shaped joint generated in a building, a civil engineering construction, or the like.

(Prior art)

Generally, in a construction or civil engineering work, a long narrow groove-like joint is formed at a joint portion of an outer wall panel or the like. Watertight the joint,
As a means for airtightly closing, a jointer is used.

A conventional joint joiner is formed in a wedge shape by an elastic body such as rubber or synthetic resin, and the joint is closed by fitting the joint in the joint.

However, in the above-described joint joiner, since the joint is merely fitted into the joint, there is a possibility that the joint joiner may come off the joint due to an impact or the like. Further, when the width dimension of the joint is not uniform, or when the inner wall surface of the joint is rough, the joint joiner follows the joint and cannot be deformed.

Therefore, as a means to solve the above problems,
As disclosed in JP-A-41505, a jointer filled with a sealing material has been devised.

The jointer is a long joiner body made of a flexible material as shown in FIGS.
Has 90. The joiner main body 90 has a substantially U-shaped cross section formed by a front wall 91 and a side wall 92, and a storage chamber 93 is formed therein. Then, a sealing material 94 is filled in the storage chamber 93.

Therefore, in use, the jointer body 90 is deformed by pushing the jointer into the joint 96 between the outer wall panels 95 as shown in FIG. As a result, the sealing material 94 in the storage room 93 flows out into the joint 96 to fill the joint 96.

[Problem to be solved]

However, in the conventional joint joiner, when the width dimension of the joint changes, the outflow amount of the sealing material varies.

That is, in a portion where the width of the joint is small, the joiner body is largely deformed, and a sufficient amount of the sealing material flows out. However, in the area where the joint width is large, the joiner body is only slightly deformed.
Low outflow of sealant. For this reason, the joint cannot be completely closed by the sealing material, and the jointer may not be able to exhibit watertight and airtight performance.

The present invention has been made in view of the above-mentioned conventional problems, and is intended to provide an joint joiner that can reliably close the joint.

[Solutions to solve the problem]

The present invention has a pair of storage compartments which are divided into left and right by a pair of left and right partition members and are filled with a sealing material, and a partition gap formed between the two storage compartments by the pair of partition members. A first joiner is provided between the left and right inner walls, and a second joiner having a projection is press-fitted into the gap between the partition walls of the first joiner. The joint joiner is characterized in that it has an outlet for letting out, and the outlet is in a temporarily closed state until the projection of the second joiner is pressed into the gap between the partition walls.

Examples of the sealing material include butyl rubber, silicone rubber, thiocol rubber, and urethane. The projections provided on the second joiner may be formed of synthetic resin, metal, hard rubber, or the like (see the first embodiment), or formed of bent sheet metal (see the second embodiment). .

It is preferable that a portion where the pair of storage chambers face each other is formed by a pair of flexible partition members. Thus, the protrusion can be easily inserted between the storage chambers.

The partition member is a member that partitions the storage chamber into a pair of left and right sides, and is disposed such that the tip end thereof approaches or contacts the outlet of the storage chamber to temporarily close the outlet. The partition member has flexibility, and is bent and deformed by a protruding body pressed into the gap between the partition walls. Means for imparting flexibility to the partition member include a method of forming the partition member from a flexible material such as a soft elastic body, and a method of forming a notch groove for bending in the partition member (see Examples). )and so on. Further, the gap between the partition walls formed between the partition members is smaller than that of the protruding body.

Further, it is preferable that the first joiner has a flexible seal lip protruding outward from a side wall of the storage chamber.

In this case, the first joiner can be securely fixed in the joint by the seal lip.

Further, it is preferable that the second joiner has a seal member for preventing the sealing material flowing out of the outlet of the storage chamber from leaking out of the joint due to the press-fitting of the protrusion.

In this case, the sealing material that has flowed out of the storage chamber can be prevented from leaking out of the joint by the sealing member, and the sealing material can be filled in the joint to reliably seal the joint.

Further, the seal lip and the seal member are formed of a flexible material such as a soft elastic body. A pair or a plurality of pairs of the seal lip and the seal member are provided in the width direction of the joint.

[Action]

In the present invention, first, the first joiner is fixed to the back of the joint. Next, the second joiner is pressed into the first joiner.

In this case, when the projection of the second joiner is pressed into the gap between the pair of storage chambers of the first joiner, the projection presses the left and right storage chambers. Then, the press-fitting of the projections releases the temporarily closed state of each storage chamber, and the outlet of the storage chamber is opened. As a result, the sealing material flows out from the left and right storage chambers equally into the joint.

〔effect〕

As described above, according to the present invention, a sufficient amount of the sealing material can always be discharged regardless of the change in the width of the joint.

In addition, since the storage chambers are provided on the left and right sides in advance, the sealing material can be uniformly discharged into the joints.

Therefore, the joint can be reliably closed.
A jointer can be provided.

An inclined surface 114 is provided in correspondence with 10. At the outlet 113 of the storage chamber 110, a protruding portion 115 protruding inward from the tip of the side wall 112 is provided.

The pair of partition members 12 are formed in a long strip shape, and their base portions are fixed to substantially the center of the inner wall surface of the bottom wall 111. Further, the distal ends of both partition members 12 are disposed so as to be close to or in contact with the distal ends of the projecting portions 115, respectively.
3 is temporarily occluded.

The partition member 12 is provided with notches 126, 127 for bending, corresponding to the bent portions 116, 117 formed on the inner wall surface of the storage room 110.

Further, between the pair of partition members 12, a partition gap 14 for press-fitting a protrusion 21 of the second joiner 2, which will be described later, is formed. The partition wall gap 14 is formed such that its entrance is wider than the tip of the projection 21.

And the storage room temporarily closed by the partition member 12
110 is filled with a sealing material 3 such as butyl rubber. As described above, the gap generated when the partition member 12 and the protruding portion 115 are brought close to each other is in a range where the sealing material 3 does not leak due to viscosity.

A plurality of the seal lips 13 project outward from a side wall 112 of the first joiner body 11 forming the storage chamber 110. The seal lip 13 is made of a soft elastic body and has flexibility.

In addition, a fixing tape 15 coated with an adhesive on both sides is attached to the bottom wall 111 of the first joiner body 11.

On the other hand, as shown in FIG. 1, the projecting body 21 of the second joiner 2 is formed in a substantially wedge shape using hard resin or rubber.
A tapered surface 210 having the same inclination angle as the inclined surface 114 is formed at the tip of the projection 21. An engagement recess 211 is formed at the base of the projection 21 so as to correspond to the projection 115 of the first joiner 1.

Further, the seal member 22 of the second joiner 2 is disposed at the base of the projection 21. The seal member 22 is made of a soft elastic body, and has a pair of lips 220 at both ends in the width direction.

Although not shown, both ends in the longitudinal direction of the first joiner are closed by a terminal piece or the like. The second
In the figure, 4 indicates a backup material.

Since the jointer of this embodiment is configured as described above, it exhibits the following operational effects.

That is, the first joiner 1 is first fitted into the concave joint 96 formed by the outer wall panel 95 and the backup material 4.

At this time, as shown in FIG.
The first joiner 1 is adhesively fixed to the backup material 4 via the fixing tape 15 by pushing the joint member 96 into the joint 96. At this time, the seal lip 13 is
Is brought into contact with the inner wall surface.

Next, as shown by an arrow in FIG. 1, the second joiner 2 is pressed into a partition gap 14 formed between the partition members 12 of the first joiner 1.

In this case, when the protrusion 21 of the second joiner 2 is slightly pressed into the first joiner 1, the protrusion 21
This causes the partition member 12 of the first joiner 1 to bend and deform toward the inner wall surface of the storage room 110. Thereby, the partition member 12
Is released, and the outlet 113 is opened. The protrusion 2
When 1 is further press-fitted into the partition wall gap 14, the protrusions 21 expand the partition wall gap 14 while further bending and deforming the partition wall member 12. As a result, the sealing material 3 in the storage room 110 gradually flows out from the outlet 113 into the joint 96 left and right.

At this time, the seal member 22 of the second joiner 2 is
Sliding contact with the inner wall surface of 96 prevents leakage of the sealing material 3 to the outside. Then, as shown in FIG.
When the front end of the sealing member 3 approaches or comes into contact with the base of the partition member 12, the outflow of the sealing material 3 stops. When almost all of the sealing material 3 in the storage room 110 flows out, the partition member 12 is bent along the inner wall surface of the storage room 110 by the cutout grooves 126 and 127. This allows the sealing material 3 in the storage room 110 to flow out without waste.

In addition, the engaging concave portion 211 of the projecting body 21 and the distal end portion of the partition wall member 12 bent and deformed by the projecting portion 115 engage. Thereby, the second joiner 2 does not come off from the first joiner, and the sealing effect can be further enhanced.

The sealing material 3 thus discharged into the joint 96 fills the joint 96 regulated by the seal lip 13 of the first joiner 1 and the seal member 22 of the second joiner 2, as shown in FIG. I do. Then, the sealing material 3 closes the joint 96.

As described above, the press-fit of the second joiner 2 into the first joiner 1 causes the seal lip 13 and the seal member 22
A sufficient amount of the sealing material 3 is forcibly discharged into the joints 96 regulated by the above, and is evenly filled to the left and right.
Therefore, even when the width dimension of the joint 96 changes, the joint 96 can be reliably closed uniformly in the left and right directions.

Second Embodiment A joint joiner according to the present embodiment will be described with reference to FIGS. In this example, the projection 61 of the second joiner 6 is formed by a bent sheet metal 610.
