Description

The present invention relates to a construction tool and a construction method used when constructing a protruding corner portion having a first plate member and a second plate member intersecting each other.

In a structure such as a building, a protruding corner portion (corner portion) protruding inward may be formed. For example, in a building such as a house, a protruding corner portion that protrudes in an L-shaped cross section may be formed at a connecting portion between side surfaces forming an indoor space or a connecting portion between a ceiling and a side surface (for example,). , See Patent Document 1 below).

FIG. 5 is a schematic cross-sectional view for explaining a conventional construction method of the protruding corner portion 100. The protruding corner portion 100 is provided at the connecting portion between the ceiling and the side surface forming the interior space, and as shown in FIG. 5, the pillar 101 extending horizontally along the ceiling and the vertical portion attached to the surface of the pillar 101. It is composed of a plate (first plate member) 102, a horizontal plate (second plate member) 103, and the like.

The vertical plate 102 and the horizontal plate 103 are formed of, for example, gypsum board. The wallpaper is finally attached to the surfaces of the vertical plate 102 and the horizontal plate 103. Therefore, it is necessary to align the tip positions of the vertical plate 102 and the horizontal plate 103 at the corners of the protruding corners 100. However, it is complicated to cut the vertical plate 102 and the horizontal plate 103 to accurate dimensions in advance before attaching the vertical plate 102 and the horizontal plate 103 to the pillar 101.

Therefore, in general, when the vertical plate 102 and the horizontal plate 103 are sequentially attached to the pillar 101, the work of cutting the tip portions thereof is performed. The vertical plate 102 and the horizontal plate 103 formed of the thin gypsum board are relatively easy to cut, and can be easily cut only by making a notch and applying stress. Therefore, even after the vertical plate 102 and the horizontal plate 103 are attached to the pillar 101, the respective tip portions can be easily cut.

Specifically, as shown in FIG. 5A, after the vertical plate 102 is attached to the pillar 101 along the vertical direction and the tip portion of the vertical plate 102 is cut along the corners of the pillar 101, The horizontal plate 103 is attached to the pillar 101 along the horizontal direction. At this time, the tip portion 130 of the horizontal plate 103 projects in the horizontal direction from the surface 121 of the vertical plate 102. A tool 104 with a sharp tip is used to cut the protruding portion (tip portion 130) of the horizontal plate 103.

First, the tip of the tool 104 is brought into contact with the connection portion 133 of the back surface 132 of the horizontal plate 103 with the front surface 121 of the vertical plate 102. Then, the tip of the tool 104 is slid horizontally along the connection portion 133. As a result, as shown in FIG. 5B, a first notch 134 extending along the connecting portion 133 is formed on the back surface 132 of the horizontal plate 103.

Next, as shown in FIG. 5B, the tip of the tool 104 is brought into contact with the surface 131 of the horizontal plate 103. At this time, the tip of the tool 104 comes into contact with the front surface 131 of the horizontal plate 103 at a position vertically facing the first notch 134 formed in the back surface 132 of the horizontal plate 103. Then, the tip of the tool 104 is slid along the direction parallel to the first notch 134. As a result, as shown in FIG. 5C, a second notch 135 extending parallel to the first notch 134 is formed on the surface 131 of the horizontal plate 103.

The first notch 134 and the second notch 135 are aligned vertically with each other. Therefore, when a force is applied to the tip portion 130 of the horizontal plate 103 as shown by the arrow 105 in FIG. 5 (c), a crack is formed between the first notch 134 and the second notch 135, and the tip of the horizontal plate 103 is formed. The portion 130 is cut. Since the first notch 134 and the second notch 135 are formed in advance, the tip portion 130 of the horizontal plate 103 can be cut so that the cut surface of the horizontal plate 103 extends straight along the connection portion 133.

Japanese Unexamined Patent Publication No. 2007-63852

However, as shown in FIG. 5B, when the tip of the tool 104 is brought into contact with the surface 131 of the horizontal plate 103, there is a problem that the tip of the tool 104 cannot be easily aligned. That is, it is not an easy task to accurately bring the tip of the tool 104 into contact with the surface 131 of the horizontal plate 103 at a position vertically facing the first notch 134 formed in the back surface 132 of the horizontal plate 103. do not have.

For example, in order to accurately align the tip of the tool 104, the distance from the tip surface 136 of the horizontal plate 103 to the first notch 134 is measured, and the tool 104 is placed on the surface 131 of the horizontal plate 103 at a position corresponding to the distance. It is conceivable to touch the tip of the. However, in this case, the work of measuring the distance from the tip surface 136 of the horizontal plate 103 to the first notch 134 and the alignment of the tip of the tool 104 with respect to the surface 131 of the horizontal plate 103 at the position corresponding to the measured distance. Work is required, and each work must be performed accurately.

In particular, when constructing the protruding corner portion 100 provided at the connecting portion between the ceiling and the side surface forming the interior space, it is necessary to perform the work at a high position with respect to the floor surface, so that each work is stable. It is difficult to do, and accurate work becomes more difficult.

And a connecting portion. The contact portion is in contact with the first plate member and slides along the first plate member. The sharp portion is arranged with a space separated from the contact portion, and the tip portion of the second plate member constructed so as to protrude from the first plate member is inserted into the space. , It is configured to face the second plate member on the side opposite to the contact portion. The connecting portion connects the contact portion and the sharp portion.

According to such a configuration, by sliding the abutting portion along the first plate member, the sharp portion can be slid on the side opposite to the abutting portion. As a result, the sharp portion can be slid in a trajectory corresponding to the surface shape of the first plate member. At this time, if the sharp portion is slid in a state of being in contact with the second plate member on the side opposite to the contact portion, a notch is formed in the second plate member in a trajectory corresponding to the surface shape of the first plate member. be able to. Then, since the tip portion of the second plate member can be cut along this notch, the protruding corner portion can be easily and accurately constructed.

(2) The sharp portion may face the second plate member at a position where the contact portion abuts on the first plate member.

According to such a configuration, it is possible to form a notch on the extension line of the surface of the first plate member with respect to the second plate member. By cutting the tip portion of the second plate member along this notch, the protruding corner portion can be constructed so that the cut surface of the second plate member is flush with the surface of the first plate member.

(3) The sharp portion may be slidable in a direction substantially parallel to the direction in which the tip portion of the second plate member protrudes.

According to such a configuration, a notch can be formed at an arbitrary position with respect to the second plate member by sliding the sharp portion to adjust the position. As a result, the degree of freedom of construction for the protruding corner can be increased.

(4) The contact portion may be configured by a rolling portion that can abut and roll on the first plate member.

According to such a configuration, when the contact portion is slid along the first plate member, the rolling portion can be slid while being rolled. As a result, the construction tool can be smoothly moved, so that the protruding corner can be constructed more easily.

(5) The construction method according to the present invention is a construction method using a construction tool, and includes an insertion step and a slide step. In the insertion step, the tip portion of the second plate member is inserted into the space. In the slide step, the contact portion is slid along the first plate member in a state where the sharp portion is in contact with the second plate member on the side opposite to the contact portion.

According to such a configuration, by sliding the abutting portion along the first plate member, the sharp portion can be slid on the side opposite to the abutting portion. As a result, the sharp portion can be slid in a trajectory corresponding to the surface shape of the first plate member. At this time, by sliding the sharp portion in contact with the second plate member on the side opposite to the contact portion, a notch is formed in the second plate member in a trajectory corresponding to the surface shape of the first plate member. be able to. Then, since the tip portion of the second plate member can be cut along this notch, the protruding corner portion can be easily and accurately constructed.

According to the present invention, a notch can be formed in the second plate member in a trajectory corresponding to the surface shape of the first plate member, and the tip portion of the second plate member can be cut along the notch, so that it is easy and easy. The protruding corner can be constructed accurately.

1. 1. Overall Configuration of Construction Tool FIG. 1 is a schematic side view showing a configuration example of construction tool 1 according to an embodiment of the present invention. This construction tool 1 (hereinafter, simply referred to as "tool 1") is used by an operator when constructing a protruding corner portion. The tool 1 includes, for example, a first guide portion 2, a second guide portion 3, a connecting portion 4, and the like. The first guide portion 2, the second guide portion 3, and the connecting portion 4 are integrally formed of, for example, metal, and are formed in a substantially U shape as a whole.

The first guide portion 2 is, for example, a rod-shaped member extending in a straight line. The root portion of the first guide portion 2 is connected to the connecting portion 4. The tip portion of the first guide portion 2 constitutes an abutting portion 21 that comes into contact with the surface of the protruding corner portion when the protruding corner portion is constructed. The contact portion 21 is formed of, for example, a flat surface.

The second guide portion 3 is, for example, a rod-shaped member extending in a straight line, and extends parallel to the first guide portion 2 with a space in between. The root portion of the second guide portion 3 is connected to the connecting portion 4. The tip portion of the second guide portion 3 extends to a position distant from the connecting portion 4 from the tip portion (contact portion 21) of the first guide portion 2. A moving member 5 that can move along the second guide portion 3 is attached to the second guide portion 3.

The moving member 5 includes a main body 51, a sharpened portion 52, and an operating portion 53. The main body 51 has a second guide portion 3 inserted therein, and can move in a straight line along the second guide portion 3. The sharp portion 52 projects from the main body 51 toward the first guide portion 2. The sharp portion 52 is tapered toward the first guide portion 2 side, and the tip is formed into a sharp blade shape.

The sharp portion 52 is arranged at a distance S from the contact portion 21. Specifically, as shown by the broken line in FIG. 1, the tip of the sharp portion 52 is located on the extension line of the plane constituting the contact portion 21 across the space S.

The operation unit 53 is operated by an operator when the main body 51 of the moving member 5 is moved with respect to the second guide unit 3. The operation unit 53 is, for example, a screw type, and the main body 51 can be fixed to the second guide unit 3 by rotating in one direction, and the main body 51 with respect to the second guide unit 3 can be fixed by rotating in the other direction. The fixing can be released.

The operator operates the operation unit 53 to release the fixing of the main body 51 to the second guide unit 3, then moves the main body 51 along the second guide unit 3, and then operates the operation unit 53 to perform the second operation. 2 The main body 51 can be fixed to the guide portion 3 again. As a result, the position of the sharp portion 52 with respect to the contact portion 21 can be moved.

2. 2. Construction method of the protruding corner portion FIG. 2 is a schematic cross-sectional view for explaining a construction method of the protruding corner portion 100. The protruding corner portion 100 is provided at the connecting portion between the ceiling and the side surface forming the interior space, and as shown in FIG. 2, the pillar 101 extending horizontally along the ceiling and the vertical portion attached to the surface of the pillar 101. It is composed of a plate (first plate member) 102, a horizontal plate (second plate member) 103, and the like.

The vertical plate 102 extends in the vertical direction, and the horizontal plate 103 extends in the horizontal direction. That is, the vertical plate 102 and the horizontal plate 103 intersect each other at an angle of 90 °. The vertical plate 102 and the horizontal plate 103 are formed of, for example, gypsum board. Since the configurations of the vertical plate 102 and the horizontal plate 103 are the same as those described with reference to FIG. 5, the same reference numerals are given to the drawings for the same configurations, and detailed description thereof will be omitted.

When constructing the protruding corner portion 100, as shown in FIG. 5A, the vertical plate 102 is attached to the pillar 101 along the vertical direction, and the tip portion of the vertical plate 102 is aligned with the corner portion of the pillar 101. Is cut, the horizontal plate 103 is attached to the pillar 101 along the horizontal direction. At this time, the tip portion 130 of the horizontal plate 103 projects in the horizontal direction from the surface 121 of the vertical plate 102. A tool 104 with a sharp tip is used to cut the protruding portion (tip portion 130) of the horizontal plate 103.

First, the tip of the tool 104 is brought into contact with the connection portion 133 of the back surface 132 of the horizontal plate 103 with the front surface 121 of the vertical plate 102. Then, the tip of the tool 104 is slid horizontally along the connection portion 133. As a result, as shown in FIG. 2, a first notch 134 extending along the connecting portion 133 is formed on the back surface 132 of the horizontal plate 103. Instead of using the tool 104, it is also possible to form the first notch 134 by using the tool 1 according to the present embodiment. In this case, the moving member 5 may be moved to the tip end side of the second guide portion 3 for use, or the moving member 5 may be removed from the second guide portion 3 for use.

Next, using the tool 1 according to the present embodiment, construction is performed on the surface 131 of the horizontal plate 103. Specifically, as shown in FIG. 2, the tip end side (opposite side to the connecting portion 4 side) of the tool 1 is brought closer to the tip end portion 130 of the horizontal plate 103 from the horizontal direction. Then, the tip portion 130 is inserted into the space S by sandwiching the tip portion 130 between the first guide portion 2 and the second guide portion 3 (insertion step).

The width of the space S (distance between the first guide portion 2 and the tip of the sharp portion 52) is, for example, about 1 to 3 cm. The thickness of the horizontal plate 103 is smaller than the width of the space S. Therefore, the tip portion 130 of the horizontal plate 103 can be smoothly inserted in the horizontal direction with respect to the space S. Then, as shown in FIG. 2, the tip portion 130 of the horizontal plate 103 is inserted into the space S until the contact portion 21 abuts on the surface 121 of the vertical plate 102, so that the alignment of the sharp portion 52 is completed. do. In this state, the tip of the sharp portion 52 faces the first notch 134 on the opposite side of the horizontal plate 103 at the position where the contact portion 21 abuts on the surface 121 of the vertical plate 102.

After that, the tip of the sharp portion 52 is brought into contact with the surface 131 of the horizontal plate 103 by slightly lifting the tool 1 upward while the contact portion 21 is in contact with the surface 121 of the vertical plate 102. That is, as shown in FIG. 2, the sharp portion 52 is in contact with the surface 131 of the horizontal plate 103 on the side opposite to the contact portion 21.

In this state, the contact portion 21 is slid along the surface 121 of the vertical plate 102 by moving the tool 1 in the horizontal direction (slide step). The moving direction of the tool 1 at this time is a horizontal direction (the front-back direction on the paper surface in FIG. 2) orthogonal to the direction in which the tip portion 130 of the horizontal plate 103 protrudes. As a result, the surface 131 of the horizontal plate 103 is scraped at the tip of the sharp portion 52, and as shown in FIG. 5 (c), the surface 131 of the horizontal plate 103 has a second extending parallel to the first notch 134. A notch 135 is formed. However, the tool 1 is not limited to the configuration in which the tool 1 is moved in a straight line in the front-back direction of the paper surface in FIG. For example, when the surface 121 of the vertical plate 102 is curved, the tool 1 is moved along the curved shape.

The first notch 134 and the second notch 135 are aligned vertically with each other. Therefore, when a force is applied to the tip portion 130 of the horizontal plate 103 as shown by the arrow 105 in FIG. 5 (c), a crack is formed between the first notch 134 and the second notch 135, and the tip of the horizontal plate 103 is formed. The portion 130 is cut (cutting step). Since the first notch 134 and the second notch 135 are formed in advance, the tip portion 130 of the horizontal plate 103 can be cut so that the cut surface of the horizontal plate 103 extends straight along the connection portion 133.

3. 3. Action effect (1) In the present embodiment, by sliding the contact portion 21 along the surface 121 of the vertical plate 102, the sharp portion 52 can be slid on the side opposite to the contact portion 21. As a result, the sharp portion 52 can be slid in a trajectory corresponding to the shape of the surface 121 of the vertical plate 102. At this time, as shown in FIG. 2, by sliding the sharp portion 52 in contact with the surface 131 of the horizontal plate 103 on the side opposite to the contact portion 21, the shape of the surface 121 of the vertical plate 102 is supported. The second notch 135 can be formed on the surface 131 of the horizontal plate 103 in the orbit. Then, since the tip portion 130 of the horizontal plate 103 can be cut along the second notch 135, the protruding corner portion can be easily and accurately constructed.

(2) Further, in the present embodiment, the sharp portion 52 faces the horizontal plate 103 at the position where the contact portion 21 abuts on the surface 121 of the vertical plate 102. Therefore, the second notch 135 can be formed on the extension line of the surface 121 of the vertical plate 102 with respect to the horizontal plate 103. If the tip portion 130 of the horizontal plate 103 is cut along the second notch 135, the protruding corner portion 100 is constructed so that the cut surface of the horizontal plate 103 is flush with the surface 121 of the vertical plate 102. Can be done.

4. Another Embodiment In the above embodiment, the case where the construction is performed on the protruding corner portion 100 so that the sharp portion 52 faces the horizontal plate 103 at the position where the contact portion 21 abuts on the surface 121 of the vertical plate 102 has been described. However, the construction method is not limited to this, and it is also possible to perform the construction with the sharp portion 52 facing the horizontal plate 103 at a position different from that in FIG.

FIG. 3 is a schematic cross-sectional view for explaining another embodiment of the construction method of the protruding corner portion 100. In the present embodiment, the first notch 134 formed in the back surface 132 of the horizontal plate 103 does not extend along the connecting portion 133 as shown in FIG. 2, but is located at a position separated from the connecting portion 133 by a predetermined distance L. One notch 134 is formed. In the present embodiment, only the position of the notch formed in the horizontal plate 103 is different from the above embodiment, and the configuration of the protruding corner portion 100 and the tool 1 is the same as that of the above embodiment. The same reference numerals are given and detailed description thereof will be omitted.

In the present embodiment, the tool 1 is used in a state where the moving member 5 is slid with respect to the second guide portion 3 from the state shown in FIG. By sliding the moving member 5 with respect to the second guide portion 3, the sharp portion 52 can slide in a direction substantially parallel to the direction in which the tip portion 130 of the horizontal plate 103 protrudes. The "substantially parallel" is a concept that includes not only a direction parallel to the direction in which the tip portion 130 of the horizontal plate 103 protrudes (the right direction in FIG. 3) but also a direction slightly inclined.

Specifically, the moving member 5 is slid from the state of FIG. 2 by the predetermined distance L, and the moving member 5 is fixed to the second guide portion 3 at the position shown in FIG. The second guide portion 3 may be formed with a scale (not shown) for measuring the moving distance of the moving member 5 with respect to the second guide portion 3. In this case, by sliding the moving member 5 according to the scale, the moving member 5 can be easily slid at an accurate moving distance.

After the first notch 134 is formed on the back surface 132 of the horizontal plate 103, the tip end side (opposite side of the connecting portion 4 side) of the tool 1 to which the moving member 5 is slid by a predetermined distance L in advance is the horizontal plate 103. It is approached from the horizontal direction to the tip portion 130 of the. Then, as shown in FIG. 3, the tip portion 130 is inserted into the space S so as to sandwich the tip portion 130 between the first guide portion 2 and the second guide portion 3 (insertion step).

Then, as shown in FIG. 3, the tip portion 130 of the horizontal plate 103 is inserted into the space S until the contact portion 21 abuts on the surface 121 of the vertical plate 102, so that the alignment of the sharp portion 52 is completed. do. In this state, at a position separated by a predetermined distance L from the position where the contact portion 21 abuts on the surface 121 of the vertical plate 102, the tip of the sharp portion 52 opposes the first notch 134 with the horizontal plate 103 in between. Facing the side.

After that, the tip of the sharp portion 52 is brought into contact with the surface 131 of the horizontal plate 103 by slightly lifting the tool 1 upward while the contact portion 21 is in contact with the surface 121 of the vertical plate 102. That is, as shown in FIG. 3, the sharp portion 52 is in contact with the surface 131 of the horizontal plate 103 on the side opposite to the contact portion 21.

In this state, the contact portion 21 is slid along the surface 121 of the vertical plate 102 by moving the tool 1 in the horizontal direction (slide step). The moving direction of the tool 1 at this time is a horizontal direction (the front-back direction on the paper surface in FIG. 3) orthogonal to the direction in which the tip portion 130 of the horizontal plate 103 protrudes. As a result, the surface 131 of the horizontal plate 103 is scraped at the tip of the sharp portion 52, and a notch (second notch) extending parallel to the first notch 134 is formed on the surface 131 of the horizontal plate 103.

If the sharp portion 52 is slid to adjust the position as in the present embodiment, a notch can be formed at an arbitrary position with respect to the surface 131 of the horizontal plate 103. As a result, the degree of freedom of construction for the protruding corner 100 can be increased. For example, when the cut surface of the horizontal plate 103 is not flush with the surface 121 of the vertical plate 102, but the cut surface of the horizontal plate 103 is projected from the surface 121 of the vertical plate 102. A construction method as in the embodiment can be used.

5. Deformation example of the contact portion FIG. 4 is a schematic side view for explaining a deformation example of the contact portion 21. In this modification, only the configuration of the contact portion 21 is different from the tool 1 in the above embodiment, and the other configurations are the same as the tool 1 in the above embodiment. A detailed explanation will be omitted.

In this modification, the contact portion 21 is composed of a rolling portion 22 that can be rolled. The rolling portion 22 is attached to the tip end portion of the first guide portion 2. The rolling portion 22 is, for example, a roller, and is rotatably held around a rotation axis extending in the vertical direction. However, the rolling portion 22 is not limited to a roller that can rotate only in a certain direction, and may be formed of, for example, a sphere that can rotate in any direction.

The surface of the outer peripheral surface of the rolling portion 22 on the tip end side (the side opposite to the connecting portion 4 side) constitutes the contact portion 21 in this modified example. The sharp portion 52 is arranged at a distance S from the contact portion 21. Specifically, as shown by the broken line in FIG. 4, the tip of the sharp portion 52 is located on the extension line of the surface on the tip side of the outer peripheral surface of the rolling portion 22 constituting the contact portion 21 with the space S interposed therebetween. is doing.

Therefore, when the tip portion 130 of the horizontal plate 103 is inserted into the space S, the contact portion 21 comes into contact with the surface 121 of the vertical plate 102, and the tool 1 is moved in the horizontal direction in that state, thereby rolling. The moving portion 22 rolls in a state of being in contact with the surface 121 of the vertical plate 102. Therefore, when the contact portion 21 is slid along the surface 121 of the vertical plate 102, the rolling portion 22 can be slid while being rolled. As a result, the tool 1 can be smoothly moved, so that the protruding corner portion 100 can be constructed more easily.

6. Other Modifications In the above embodiment, the configuration in which the distance between the first guide portion 2 and the second guide portion 3 is fixed by the connecting portion 4 has been described. However, the configuration is not limited to such a configuration, and a configuration in which the distance between the first guide unit 2 and the second guide unit 3 can be adjusted may be used. In this case, for example, a structure that can be expanded and contracted may be adopted for the connecting portion 4, or a structure including an elastic member such as a spring may be adopted.

As a result, the distance between the first guide portion 2 and the second guide portion 3 can be adjusted according to the thickness of the horizontal plate 103 inserted into the space S, and the width of the space S can be adjusted to the thickness of the horizontal plate 103. can. In this case, when the tip portion 130 of the horizontal plate 103 is inserted into the space S, the tip of the sharp portion 52 can be brought into contact with the surface 131 of the horizontal plate 103. Therefore, a cut (second cut) can be easily formed in the surface 131 of the horizontal plate 103 simply by moving the tool 1 in the horizontal direction as it is.

Further, the configuration may be such that a sharp portion is provided not only on the second guide portion 3 side but also on the first guide portion 2 side. That is, the configuration may be such that sharp portions are provided on both sides of the horizontal plate 103. In this case, the tips of the sharp portions may be fixed so as to face each other with the horizontal plate 103 interposed therebetween, or at least one of the sharp portions may be slidable. If the structure is such that sharp portions are provided on both sides of the horizontal plate 103, it is possible to easily form cuts on both the front surface 131 and the back surface 132 of the horizontal plate 103 by using one tool 1. can.

The operation unit 53 is not limited to the screw type, but has a configuration such that the moving member 5 can be switched to be fixed or released from the second guide unit 3 by another method, for example, a lever type. It is also good. Further, the sharp portion 52 is not limited to the configuration provided in the movable member 5 that can move with respect to the second guide portion 3, and may be fixed to the second guide portion 3.

The protruding corner portion 100 is not limited to the configuration provided at the connecting portion between the ceiling and the side surface forming the interior space, but may be provided at the connecting portion between the side surfaces forming the interior space. Further, the protruding corner portion 100 is not limited to a configuration having a first plate member (vertical plate 102) and a second plate member (horizontal plate 103) orthogonal to each other, and the first plate member intersects with each other at an angle other than 90 °. And may be configured to have a second plate member. That is, the tool 1 according to the present invention can be used for construction of an arbitrary protruding corner portion having a first plate member and a second plate member that intersect each other.
