Description

  The present invention relates to an auxiliary tool for cutting a sealing material and a method for cutting a sealing material using the auxiliary tool.

When the sealing material filled in the joints such as the outer wall has deteriorated over time, it is necessary to cut off the deteriorated sealing material from the outer wall as the adherend and fill it with a new sealing material. At the time of this excision work, it has been usual to cut a sealing material near the adherend with only a cutter. When the adherend is a hard material such as stone or metal, it is possible to move the cutter held by the hand along the adherend, so that sealing is performed at the boundary between the adherend and the sealant. You can cut the material neatly. However, if the adherend of the sealing material is a soft material such as lightweight cellular concrete such as ALC (Autoclaved Lightweight Concrete), siding material, rubber material, etc., the cutter held by the hand and the sealing material It is not easy to move along the boundary, and it is necessary to cut the adherend accidentally, and it takes time to repair it, or conversely, the sealing material cannot be completely removed and the excision work must be repeated many times. There are things that must be done.
In order to solve such a problem, it is conceivable to move the cutter along the ruler, but the ruler moves due to the force applied during the work, and as a result, it is not possible to cut into the assumed shape. There's a problem.

For example, a joint removing material for fixing a joint guide to the adherend with a suction cup fitting has been devised (see Patent Document 1). However, in the method using such a metal fitting, the surface of the adherend must be smooth like a tile and sucked by the suction cup, and the adherend should be a surface such as ALC, concrete, siding material, etc. In the case of non-smooth materials and finishes, fixing was impossible. In addition, even when attachment is possible, there is a problem that attachment takes time.
On the other hand, a method of fixing the ruler to the adherend using screws or the like is conceivable. However, this method damages the adherend, and labor is required to repair the screw marks, resulting in poor workability.

  That is, there is a tool or method for cutting a sealing material into a desired shape without damaging the adherend, even if the adherend is a soft material that is easy to fix and remove from the above circumstances. It was desired.

  Hereinafter, the present invention will be described in detail on the basis of the embodiments. However, these embodiments are described in order to help understanding of the present invention, and are intended to limit the present invention to the described embodiments. It is obvious that there is nothing.

In the following embodiment, as shown in FIG. 1 (a), a wet sealing material 4 (deteriorated) filled into a concave sealing pocket 3 in a vertical joint portion 2 of an adherend 1 (outer wall made of an ALC panel) is deteriorated. The urethane sealing material) will be described as an object of excision.
As shown in FIG. 1A, the sealing pocket 3 has a cross-sectional shape like a countersunk screw, and the sealing material 4 filled therein also has a cross-sectional shape like a ridge with a plateau.

(Embodiment 1)
The sealing material excision assisting tool 5 according to this embodiment is used when the sealing material 4 filled in the joint portion 2 of the adherend 1 is excised with a cutter. It has a long main body 6, a contact surface 7 that is provided along the length direction of the main body and is used to contact the cutter and cut the sealing material, and has a sharp tip shape. A sealing material excision assisting tool 5 is provided, which is provided with a penetrating portion 8 for penetrating the sealing material 4 to be excised and maintaining the position of the corresponding contact surface 7.
The sealing material excision assisting tool 5 having the above configuration is easy to fix and remove, and even if the adherend 1 is a soft material, the sealant 4 is excised in a desired shape without damaging the adherend 1. Make it possible.

As shown in FIG. 1A, the main body 6 has a long shape, and a plurality of penetrations 8 are provided on the bottom surface that is in contact with the sealing material 4.
The main body 6 or the penetration 8 may be made of any material, but is preferably made of a metal such as stainless steel or aluminum alloy in consideration of accuracy and durability.

The width of the main body 6 is preferably equal to the width of the sealing material 4 to be cut. That is, it is preferable that the distance between the contact surfaces 6 on both sides to be described later is equal to the width of the sealing pocket 3 in which the sealing material 4 is filled.
If it does in this way, after making one notch | incision, the other notch | incision can be made without installing the sealing material cutting assistance tool 5 again.

  The length of the main body 6 is not particularly limited, but is preferably 1 m to 1.5 m in consideration of ease of handling when used at a construction site.

  The contact surface 7 is provided on both surfaces or one surface of the main body 6 along the length direction of the main body 6. The contact surface 7 preferably has a shape that allows the cutter to be easily moved when the cutter is moved to make a cut, and is preferably a flat surface as shown in FIG. Alternatively, the contact surface 7 may be provided with a predetermined angle with respect to the penetration portion 8 described later.

  In order for the penetration part 8 to have a structure that is easy to stick into the sealing material 4 and easy to remove, it is desirable that the tip has a trapezoidal shape as shown in FIG. The interval between the penetration portions 8 is preferably about 50 to 200 mm, and 100 mm is preferable because it is easy to use.

  In the example of FIG. 1A, the penetration portions 8 are provided in one row. However, for example, when the width of the sealing material 4 is wide, the main body portion 6 can be held more stably by using a plurality of rows. .

  The penetrating part 8 may be a member different from the main body part 6 so as to be exchangeable when damaged, or may be formed in the main body part 6.

  Moreover, in order to make it easy to hold | maintain with a hand, it is preferable to attach a handle as shown to Fig.1 (a) to the main-body part 6. FIG.

  Next, a sealing material excision method using the sealing material excision assisting tool according to the present embodiment will be described. The procedure for cutting the sealing material is as follows.

(1) First, the penetration portion 8 is pierced into the center of the sealing material 4 to be cut (FIG. 2A). The main body portion 6 is strongly held by piercing the plurality of penetration portions 8, and a shift when the cutter is moved along the main body portion 6 can be prevented.

(2) The sealant 4 and the adherend 1 are held by holding with one hand so that the main body 6 does not tilt, and moving the cutter (cutter blade 10) along the contact surface 7 with the other hand. A cut is made in the boundary surface of FIG. 2 (b).

(3) Change the hand that operates the cutter and the hand that holds the sealing material cutting aid 5 and cut the other boundary surface. In this example, since the width of the main body portion 6 of the sealing material cutting aid 5 is equal to the width of the sealing material 4 to be cut, the operation can be continued only by changing hands.

(4) After making incisions on both sides of the part to be cut, the end of the sealing material 4 is picked out and pulled to remove the sealing material of the substantially rectangular cross-section at the center (FIG. 2 (c)).
Since the sealing material 4 filled in the sealing pocket 3 is filled with a primer applied on the side surface of the sealing pocket 3, the sealing material 4 has a strong adhesive force. Since the primer is not applied, the adhesive strength is not strong. Therefore, it can be easily removed by making a cut in the side surface portion of the sealing pocket 3 with a cutter.

  In addition, although the hole remains in the sealing material 4 in which the penetration part 8 was penetrated, since the sealing material 4 is removed after cutting, it is not necessary to repair such a hole.

When the adherend 1 is a soft material such as lightweight cellular concrete such as ALC, siding material, or rubber material, the width of the main body 6 is preferably slightly larger than the width of the sealing pocket 3 to be cut. For example, when the width of the sealing pocket 3 filled with the sealing material 4 is 7 mm, the width of the main body 6 is preferably about 10 mm.
By doing in this way, when making a cut with a cutter, the cut is made in the adherend 1 in the vicinity of the boundary surface between the sealing material 4 and the adherend 1, and the adherend 1 is cut out together with the sealing material 4. Thus, the side surface of the new sealing pocket 3 is exposed by slightly cutting the side surface of the sealing pocket 3 of the adherend 1. Since there is no remaining sealing material on such a new surface, a desired adhesive force can be obtained when the sealing material is newly filled. That is, in the above description, there is a notch in the boundary surface between the sealing material 4 and the adherend 1, but when the adherend 1 is a soft material, it is not necessary to accurately cut in the boundary surface.

  In addition, after cutting off the substantially rectangular section at the center using the sealing material cutting aid 5, part of the sealing material remains on the inclined adhesive surfaces on both sides (see FIG. 2C). The remaining sealing material may be excised using an inclined surface excision assisting tool 11 as shown in FIG.

FIG. 3 is a cross-sectional view in the length direction of the cutting aid 11 for inclined surfaces. As shown in FIG. 3, the inclined surface resection assisting tool 11 includes an inclined contact surface 12 that is inclined in accordance with the inclination angle of the inclined surface of the adherend 1 on which the sealing material remains. In addition, a buffer member made of a material having elasticity such as rubber, a handle for holding by a hand, and the like are provided at a portion that contacts the adherend 1.
The length of the inclined surface resection aid 11 is not particularly limited, but is preferably 1 m to 1.5 m in consideration of ease of handling when used on a construction site.

  By moving the cutter along the inclined contact surface 12 of the inclined surface resection assisting tool 11, the sealing material remaining on the inclined portion of the adherend 1 can be removed.

(Embodiment 2)
The sealing material excision assisting tool according to Embodiment 2 is further provided with a stabilizer that is provided at an end of a portion that extends substantially perpendicular to the length direction of the abutting surface and that abuts against the surface of the adherend. It is characterized by that.
By providing such a stabilizer, it is possible to prevent the sealing material cutting aid from being tilted when the cutter is strongly applied.

The second embodiment is the same as the configuration of the first embodiment except that a stabilizer is provided at the end of the extended portion, and the description thereof is omitted.
FIG. 4A is a perspective view of a sealing material excision assisting tool including the stabilizer 13. FIG. 4B is a cross-sectional view of a sealing material excision assisting tool provided with the stabilizer 13.

  As shown in FIG. 4, by providing a stabilizer 13 at the end of a portion that extends substantially perpendicular to the length direction of the main body 6, the main body 6 tilts when a force is applied to the main body 6 or the sealing material 4. Can be prevented from coming off. In this example, the contact surface 7 is provided only on the side opposite to the surface on which the stabilizer 13 is provided.

In order to prevent damage to the adherend 1, a buffer member made of a material having elasticity such as rubber may be continuously or intermittently attached to the portion where the stabilizer 13 contacts the adherend 1.
The stabilizer may be long and continuous as shown in FIG. 4, or may be intermittent composed of a plurality of short pieces. In the former case, the connecting portion between the contact surface 7 and the stabilizer 13 may be long and continuous, or may be intermittent composed of a plurality of short pieces.

(Embodiment 3)
The sealing material resection assisting tool according to Embodiment 3 is characterized in that the contact surface is movable in a direction substantially perpendicular to the length direction of the main body.
By making the contact surface movable, it is possible to cope with sealing materials of various widths.

  In the third embodiment, the configuration is the same as that of the first embodiment except that the contact surface 7 is movable in a direction substantially perpendicular to the length direction of the main body 6, and the description thereof is omitted.

  For example, as shown in FIG. 5, the mechanism for making the contact surface 7 movable with respect to the length direction of the main body 6 is a main body obtained by dividing the movable plate 14 provided with the contact surface 7 into two parts. It is good also as a structure pinched | interposed by (the upper side main-body part 15 and the lower side main-body part 16). In this structure, the relative position between the penetrating part 8 and the contact surface 7 is changed by moving the movable plate 14 to a desired position and then sandwiching the movable plate 14 between the upper body part 15 and the lower body part 16 by the fixing bolt 17. Can be made. Thereby, it can respond to the sealing material of various widths.

FIG. 6 is an example of the movable plate 14. The shape of the abutment surface 7 of the movable plate 14 does not need to be a straight line, and for example, as shown in FIG. 6, it can be curved according to the shape of the joint.
As shown in FIG. 6, the movable plate 14 is preferably formed with a groove through which the fixing bolt 17 is inserted. Further, the movable plate 14 is formed with notches (for example, intervals corresponding to existing sealing pocket standards) formed at regular intervals so as to contact the movable plate 14 of the upper body portion 15 or the lower body portion 16. It is preferable to provide a protrusion that fits the notch on the surface to be processed. By doing in this way, it becomes easy to adjust the position of the contact surface 14.

  In addition, by providing the movable plate 14 as described above, not only the position of the contact surface 7 can be adjusted, but also a contact surface having a different shape can be set and used. It can correspond to a sealing material filled in a shape.

  The sealing material excision assisting tool and the sealing material excision method according to the present invention have been described above. However, the sealing material excision assisting tool and the sealing material excision method according to the present invention are applicable to the machine industry and electronic components in addition to the general construction industry. It can also be used effectively as a cutting ruler for wood sealing, or as a wood cutting ruler.
