Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a dry joint material.
[0002]
[Prior art]
As shown in FIGS. 4 (a) and 4 (b), for example, as a joint waterproof structure such as an outer wall, a rubber having a core 51 and fins 52 projecting from the core 51 to both sides is provided. The dry type joint material 53 is used, the dry type joint material 53 is mounted as a secondary waterproofing material in the back of the joint 54, and the sealing material 55 is filled in the front side of the joint 54. is there.
[0003]
[Problems to be solved by the invention]
For example, in this joint waterproof structure, if the dry joint material 53 is to be mounted in the interior of the joint 54, as shown in FIG. There was a problem that it was quite difficult to install in the state.
[0004]
This invention is made | formed in view of this problem, Comprising: It aims at providing the dry joint material of a structure which can be reliably mounted | worn in a proper attitude | position state in a joint.
[0005]
[Means for Solving the Problems]
The above-mentioned problem is that a dry joint material having a core part and having fins protruding from both sides of the core part can be used for mounting a joint material that opens or opens on the front side of the core part. This is solved by a dry joint material characterized in that a simple groove is provided.
[0006]
Since this dry joint material is provided with a groove on the front side of the core part, a jig for mounting the joint material is inserted into this groove, and with this jig, the orientation of the dry joint material is fixed in a certain direction. Accordingly, the dry joint material can be reliably mounted in an appropriate posture in the joint.
[0007]
In addition, since the groove is provided in the core portion, it is possible to form a groove having a depth necessary for fixing the orientation of the dry joint material in a fixed direction with a jig, and the formation of this groove can improve the waterproof performance. The function as a joint material is not impaired.
[0008]
Further, the above problem can be basically solved by a dry joint material characterized in that a groove that can be used for mounting a joint material that opens or opens on the front side is provided.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0010]
In the joint waterproof structure shown in FIG. 1 (b), 1 is a joint, 2 is a waterproofing band that also functions as a backup material, 3 is a dry joint material as a secondary waterproofing material, and 4 is an irregular shape as a primary waterproofing material. It is an elastic sealing material. A waterproofing band 2 is provided behind the joint 1, a dry joint material 3 is attached to the back of the joint 1, and a sealing material 4 is filled on the front side of the joint 1.
[0011]
In this joint structure, the dry joint material 3 is made of a rubber-like material having elasticity. As shown in FIG. 1 (a), the core part 5 and the fins protruding from the core part 5 on both sides are provided. 6 ..., and the elasticity of the fins 6 ... absorbs the dimensional error of the joint 1 and also elastically deforms following the movement of the joint 1 due to temperature changes etc. It is made to keep on.
[0012]
In the dry joint material 3, a slit-like groove 7 having a predetermined depth that opens or opens on the front side of the joint material 3 is formed in the center portion on the front side, that is, the portion corresponding to the core portion 5. As shown in FIG. 2, a joint material mounting jig 8 can be inserted into the groove 7.
[0013]
The joint material mounting jig 8 includes an insertion portion 9 to be inserted into the groove 7 and a handle portion 10 so that the insertion portion 9 can be inserted into the groove 7 by holding the handle portion 10. It has become. The insertion part 9 has a plate-like form and prevents the dry joint material 3 from swinging left and right in a state of being inserted into the groove 7 and fixed with the handle part 10. It is. That is, the dimensions of the depth, width and length of the groove 7 are such dimensions that such a free-running movement in the left-right direction is restricted when the insertion portion 9 of the jig 8 is inserted into the groove 7. Is set to
[0014]
The above-described dry joint material 3 is attached to the joint 1 in a state where the insertion portion 9 of the jig 8 is inserted into the groove 7 of the dry joint material 3 as shown in FIG. The holding part 10 is held, and in this state, the dry joint material 3 is pushed into the joint 1 and set at a predetermined mounting position. In this mounting operation, the dry joint material 3 tends to swing left and right in the process of being pushed into the mounting position in the joint 1, but this swing is prevented by the insertion portion 9 of the jig 8, thereby causing the dry joint material 3 to move. 3 is mounted at a predetermined mounting position without swinging left and right. Thus, according to the dry joint material 3 described above, the dry joint material 3 can be reliably mounted in the joint 1 in an appropriate posture state. Finally, the jig 8 is pulled out as shown in FIG.
[0015]
In order to prevent the dry joint material 3 from being pulled out from the joint 1 during this extraction, for example, the insertion portion 9 of the jig 8 is formed in a cross-sectional shape that narrows toward the tip side. It is also possible to design the dimensions so that the opposite surfaces of the groove 7 do not abut the both sides of the insertion portion of the jig 8 strongly. In short, the jig 8 is used. Then, after mounting the dry joint material 3, it is only necessary that the jig 8 can be removed without accompanying the dry joint material 3 to the jig 8.
[0016]
In addition, the mounting method is not limited to the method described above. For example, if the dry joint material 3 is mounted in the joint 1 with a fingertip or the like alone, depending on the mounting state, Using such a jig 8 or other jig as described above, the insertion portion 9 is inserted into the groove 7 of the dry joint material 3, and the orientation is corrected to a predetermined proper mounting state. You may take a method.
[0017]
Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above embodiment, the dry joint material 3 having a specific form is shown. However, the present invention is not limited thereto, and the dry joint material of the present invention includes a core part that can form a groove, and the core part. It may consist of various forms with fins projecting on both sides. Further, the number and form of fins and the form of the core part may be various forms, and the form of the groove is formed in various forms in relation to the jig to be used. It's okay. Further, the dry joint material 3 may be a rubber-like material having elasticity, a composite of a hard part and a rubber-like part, or a structure having a fin having flexibility. These may be of various structures. Further, the dry joint material of the present invention may not be the secondary water stop material as in the above embodiment, but may be used as a water stop material used alone or as a backup material for joints. May be. The joint material of the present invention is not limited to the outer wall joint, and may be configured as a joint material for various joints.
[0018]
