Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for peeling off a joint material which is filled and solidified in joints which are concave grooves formed between panels of a curtain wall, between tiles, around a sash and the like. Regarding a joint material stripping machine.

[0002]

2. Description of the Related Art Conventionally, a joint material that has been filled into a joint and solidified is peeled off by manually cutting a cutter such as a cutter knife along both side walls of the joint (FIG. 7). It is performed by grasping the lifted tip side by hand and pulling it toward the hand side (FIG. 8), or by using a so-called keren tool having a sharp cutting edge.

[0003]

However, in these methods, the joint material is cut off if the user is not very accustomed to it, and the work efficiency is poor, and it is dangerous to use the tool by directly grasping the tool, Further, it is unexpectedly difficult to insert the cuts along both side wall surfaces of the joint without interruption, and thus the joint material is partially left.

Therefore, the present invention is to enable the joint material to be peeled off safely, easily and surely.

[0005]

A joint material stripping machine of the present invention comprises a base 1 having stripping blade mounting window holes 2 and cutter mounting grooves 4, 4 '. In the stripping blade mounting window 2, a stripping blade 5 that is pushed between the bottom surface of the joint 22 and the joint material 21 is detachably mounted. Further, cutters 6 and 6 ′ which are pushed between the both side wall surfaces of the joint 22 and the joint material 21 are detachably attached to the cutter mounting grooves 4 and 4 ′. The base 1 is also provided with a handle mounting groove 3 to which a handle 7 is detachably mounted, and when the handle 7 can be gripped for work, the base 1 itself is hooked. It is easier to work as compared with the case of directly grasping and working.

[0006]

[Operation] In the stripping work of the joint material, the cutter is pushed in between both side wall surfaces of the joint and the joint material, and similarly, the tip of the stripping blade is pushed in between the bottom surface of the joint and the joint material. As a result, the base is pressed against the surface of the joint so as to cover it and the free end side of the joint material is stripped off from below through the stripping blade mounting window hole, and the base is pressed in the contact state. When pulling slowly to the side, the cutter cuts the bond between the joint material and the wall surfaces on both sides of the joint, and the peeling blade also cuts the bond between the joint material and the bottom surface of the joint, and the joint material becomes the peeling blade on the tip side. It will automatically come out upwards from the window as it goes along.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments shown in the drawings will be described in detail below.
Reference numeral 1 is a substantially rectangular parallelepiped base, 2 is a stripping blade mounting window provided in one half of a longitudinal direction of the base 1 in a plane rectangular shape, 3
Is a notch-shaped handle mounting groove formed at the other end. Reference numerals 4 and 4 ′ are cutter mounting grooves formed in the same notch shape formed on both side surfaces orthogonal to the longitudinal direction between the window hole 2 and the mounting groove 3. Reference numeral 5 is a stripping blade to be mounted in the mounting window 2, 6, 6'is a cutter to be mounted in the mounting grooves 4, 4 ', and 7 is a handle to be mounted in the mounting groove 3.

Reference numeral 8 is a locking tool for mounting and tightening the stripping blade 5 in the window hole 2. The locking tool 8 has two bolts 10 planted in a connecting piece 9 and screwed thereto. It consists of two nuts 11. The stripping blade 5 is inserted into the window hole 2 in a state in which the required blade edge length is projected downward, and the bolts 10 of the locking tool 8 are inserted through the corresponding through holes 2 from one outside of the base 1. The nuts 11 are threadedly fastened to the window holes 2 by penetrating through ′ and 5 ′ and projecting to the outer ends of the base 1 on the other side.

Reference numeral 12 is a locking tool for mounting and tightening the cutters 6, 6'into the mounting grooves 4, 4 '.
The reference numeral 2 is composed of two nuts 15 in which two bolts 14 are planted in the connecting piece 13 and screwed together. The cutters 6,6 'have spacers 16,16' inside them,
With the outer contact pieces 17, 17 'superposed on the outside, the mounting grooves 4, 4'are made in a state where the required length of the cutting edge is projected downward.
To the bolts 14 of the locking tool 12 from the outer contact piece 17
Through the corresponding insertion holes 18, 18 'and 1',
Nuts 1 are attached to the tips of the circumscribing pieces 17 'that project outward.
By screwing and tightening 5, the mounting grooves 4, 4 '
It is installed and tightened on. Since the spacers 16 and 16 'are used to adjust the interval between the cutters 6 and 6'according to the width of the joint, it is desirable to prepare a plurality of spacers having various thicknesses.

Reference numeral 19 denotes three bolts for mounting the handle 7 in the mounting groove 3, and 20 denotes a nut screwed to the bolts. The handle 7 is provided with a projecting piece 7 ′ having an arcuate upper surface on its front end surface, and this projecting piece 21 is fitted into the mounting groove 3 and positioned on the left and right wall portions of the mounting groove 3 at each vertex of an equilateral triangle. The three insertion holes 3'provided in the above and the three insertion holes 7 "provided in the projecting piece 7'at the respective apexes of the equilateral triangle are located from the outside on one side thereof. The three bolts 19 are inserted, and nuts 20 are screwed and tightened at their tips projecting outward on the other side, so that they are mounted and tightened in the mounting groove 3.

To remove the joint material, the cutters 6, 6'are pushed in along the inner surfaces of both side walls at the required positions of the joint 22 filled with the solidified joint material 21, and the peeling blade 5 is removed. The stripping blade 5 is pushed in so as to traverse the required position of the joint material 21, whereby the base 1 is pressed and abutted so as to cover the surface of the joint 22, and the free end side 21 ′ of the joint material 21. Through the window 2 from above to above (FIG. 6).

In the pressed contact state, the base 1 is slowly pulled to the hand by the handle 7, whereby the joint material 21
Cutters 6 and 6 ′ are pressed between the joint and the both side wall surfaces of the joint 22 to cut the bond between them and the peeling blade 5 is also pressed between the joint material 21 and the bottom surface of the joint 22 to cut the bond. The joint material 21 comes out upward from the window hole 2 along the stripping blade 5 at the tip side 21 '.

[0013]

As is clear from the above description,
The present invention has the following effects. Place the cutter between the joints on both side walls of the joint and the joint material, place the blade edge of the stripping blade between the joint bottom and the joint material, and pull the base slowly at hand. The cutter cuts the bond between the joint material and the wall surfaces on both sides of the joint, and the stripping blade also cuts the bond between the joint material and the bottom surface of the joint, and the joint material moves upwards from the window while aligning the tip side with the stripping blade. Come out.

That is, according to the present invention, even if a beginner does not require special skill as in the prior art, the joint material can be stripped efficiently, safely, easily and surely without breaking the joint material. .
