Description

  The present invention relates to a joint width adjusting jig for adjusting the joint width formed when standing a building structure.

For example, when an outer wall or the like is erected, a plurality of outer wall panels may be used.
Thus, when an outer wall is constituted by combining a plurality of outer wall panels, a space (joint) is formed between adjacent outer wall panels.
These joints need to have a certain width because of appearance problems, and the joints are waterproofed, so that the joint width is a certain specified width to ensure waterproof performance. Need to be.
Therefore, it is necessary to adjust the joint width (enlarge it to the specified joint width). Conventionally, a hard member such as a bar is inserted into the joint, and the joint width is expanded by the lever principle. .
A method for adjusting the joint width using a dedicated jig has also been proposed (see, for example, Patent Document 1).

Patent Document 1 discloses a jig for opening a joint width.
This jig has a pair of pressing parts, pins, and opening parts.
In addition, the opening part is configured to have a lever that acts as an action point of force and an opening main part, and the opening part (opening main part) is a pressing part centered on the pin. It is comprised so that it can rotate with respect to.
The pushing part is inserted into the joint space, and the opening part is rotated by applying a force to the lever while the pushing part is inserted into the joint space.
When the opening part rotates, the opening main body part enters between the paired pressing parts, and the interval between the paired pressing parts is expanded.
With this expansion, the joint width is configured to open.

Thus, in the conventional technique and the technique of Patent Document 1, the joint width can be expanded.
However, when the joint is adjusted in this way, if a high force is applied using a high-level tool such as a bar or a jig described in Patent Document 1, an outer wall generally formed of a ceramic material The exterior material (face material) was considered to be damaged.
Further, regarding the joint width, an inspection for confirming whether or not the width is as specified is also necessary. In the past, this inspection jig and the joint width increasing jig as in the prior art are required. Multiple jigs with tools were required.
Therefore, it has been desired to propose a jig that can easily inspect and expand the joint width.

  An object of the present invention is to solve the above-described problems, and it is possible to adjust joint width without damaging the exterior material, and to perform joint width inspection and adjustment together. It is to provide a joint width adjusting jig.

The above-described problem is a joint width adjusting jig for adjusting the joint width according to the joint width adjusting jig according to the present invention , and the joint width adjusting jig includes an action point to which a force is applied, and A force acting part, and an elongate body extending from the force acting part, and an adjusting part formed with a force point for applying a force to the joint inner wall surface, and the adjusting part Is a rod-shaped portion that is a circular rod-shaped cross section that extends from the force acting portion, and two plate-shaped adjustment pieces that are affixed to the outer surface of the rod-shaped portion at the tip of the rod-shaped portion. The two adjustment pieces are arranged in a point-symmetrical position with respect to the center point in the cross-sectional shape, and the adjustment is performed by aligning the direction of the shortest diameter with the width direction of the joint. After inserting the part into the joint, by rotating the adjustment part, the direction of the longest diameter of the adjustment part is It is solved by extending the joint width in alignment direction.

As described above, in the joint width adjusting jig according to the present invention, the cross-sectional shape at the position serving as the power point of the adjusting portion is formed in a shape having a plurality of diameters.
Therefore, if the direction of the shortest diameter is inserted in alignment with the joint width, the rotational force applied to the force acting part is applied to the force point of the adjusting part, and the longest diameter of the force point is matched with the joint width, According to the principle, the joint width matches the length of the longest diameter of the power point cross section.
Thus, in the present invention, the joint width can be expanded by rotating the adjusting portion.
For this reason, the width of the joint is not expanded with a material such as a bar, and the width of the joint is not expanded with a strong force unlike the conventional example, so that the joint surface is not damaged. The width can be adjusted.

At this time, as described in claim 2, it is preferable that the longest diameter among the diameters of the positions serving as the power points of the adjustment portion is formed so as to match a specified value of the width of the joint. is there.
If comprised in this way, the width | variety of a joint can be expanded by rotating an adjustment part, and it can be made to match | combine with the regulation value of a joint width easily.
Therefore, the joint width adjustment can be performed easily and reliably.
In addition, since the longest diameter is configured to be the prescribed value of the joint width, the joint width becomes the prescribed value by inserting the longest diameter into the existing joint by aligning with the joint width direction. Can be easily inspected.
In other words, if the press fit can be performed, the joint width is appropriate, but if the insertion is impossible, it is determined that the joint width is too small. It becomes possible.
As described above, the joint width adjusting jig according to the present invention has a function of inspecting whether or not the joint width is a specified value in addition to the function of adjusting the joint width to the specified value.

Further, as a specific configuration, as described in claim 3, the cross-sectional shape of the position to be the force point of the adjustment portion is an elliptical shape, and the long axis length that is the longest diameter is the joint of the joint. It is good to form so that it may match with the regulation value of a width.
A cross-sectional figure having a plurality of diameters can be variously assumed. However, when the figure is an ellipse, two diameters can be easily secured by the major axis and the minor axis.
Thus, by rotating the adjusting portion, the width of the joint can be easily and reliably adjusted only by aligning the long axis length, which is the longest diameter, with the width of the joint.

Furthermore, as described in claim 4, the shortest diameter of the position serving as the power point of the adjustment portion is formed to be slightly smaller than an allowable minimum value of a prescribed value of the joint width. Is preferred.
If configured in this way, it can be easily inserted into the joint of the allowable minimum value, and if this cannot be inserted, the joint width is obviously too small, and therefore also for inspection. Can be used.

The adjustment portion is a rod-like portion that is a circular rod-shaped cross section extending from the force acting portion, and two plate-like members that are attached to the outer surface of the tip of the rod-like portion and serving as the power point. The two adjustment pieces are arranged in a point-symmetrical position with respect to the center point in the cross-sectional shape, so that the longest diameter and the shortest diameter are the same as in the elliptical cross-sectional shape. And can be created.
That is, if the cross-sectional diameter of the rod-shaped part is t1, and the thickness of the adjustment piece of the plate-like body is t2,
t1 + 2 × t2 = longest diameter.

According to the present invention, the width of the joint can be easily adjusted only by applying a rotational force to the action point and applying the rotational force to the force point, and the joint width can be adjusted by the rotational force. Therefore, joint width adjustment can be performed without damaging the exterior material.
Furthermore, according to the present invention, joint width inspection and adjustment can be performed together.

The major axis length y of the substantially elliptical cross section is configured to be a normal dimension of the joint width.

FIG. 4 shows the procedure.
FIG. 4A shows a joint width adjusting jig 1 according to this embodiment.
Using this joint width adjusting jig 1, as shown in FIG. 4B, first, the minor axis is inserted into the joint M in the width direction (horizontal direction).
If it cannot be inserted, the joint width of the joint M will be too small, and it can be used for checking whether the minimum joint width can be maintained.
And in this state, as shown in FIG.4 (c), the force of the rotation direction is applied to the force action part 11, and the joint width adjustment jig | tool 1 is rotated.
At this time, if the joint width is smaller than the major axis length, the joint width is widened by the principle of lever accompanying rotation, and the major axis can be aligned in the width direction (horizontal direction) as shown in FIG. For example, the joint width is adjusted to the long axis length, that is, to the specified value.

At the time of inspection, if the major axis is aligned in the width direction (horizontal direction) and inserted into the joint M, the width of the joint M with respect to the reference value can be confirmed.
That is, if it can be inserted with a margin, it can be determined that the joint width is larger than the specified value, and if it cannot be inserted, it can be determined that it is smaller than the specified value.
If the value is smaller than the specified value, the steps shown in FIGS. 4B to 4D may be executed to match the joint width to the specified value.

(First modification)
Next, FIGS. 5 and 6 show a first modification.
In the joint width adjusting jig 1 according to the first modified example, the shape of the adjusting unit 12 of the above embodiment is modified.
The adjustment unit 12 according to this example includes an adjustment operation unit 12a and a connection unit 12b.
The connecting portion 12 b is a rod-like body that extends from the central portion of one long side of the force acting portion 11.
In this example, a rod-shaped body having a circular cross-sectional shape is used, but the cross-sectional shape is not particularly limited and may be any shape such as an ellipse, a rectangle, or a polygon.
Moreover, the adjustment action part 12a which concerns on this example is a block body of a substantially elliptic cylinder shape.

The bottom surface (cross-section) shape of the adjusting action portion 12a is configured to have the dimensions shown in FIG. That is, the minor axis length x of the bottom surface (cross-section) substantially ellipse is designed to be equal to or less than the allowable minimum joint width (slightly smaller than the allowable joint width), and the major axis length y Is configured to have a normal dimension of the joint width.
And the diameter of the connection part 12b is comprised so that it may become smaller than the major axis length y of the adjustment effect | action part 12a.
That is, the diameter of the connecting portion 12b extending in the same direction as the direction in which the long axis of the adjusting action portion 12a extends is configured to be smaller than the long axis length y of the adjusting action portion 12a.

Then, as shown in FIG. 6, the adjustment unit 12 is inserted into the joint M, and, as in FIG. 4, a force by rotation is applied to the force application unit 11, and the adjustment operation unit 12 a is rotated according to the lever principle.

In this example, a rod-shaped body having a circular cross-sectional shape is used, but the cross-sectional shape is not particularly limited and may be any shape such as an ellipse, a rectangle, or a polygon.
In addition, the bottom surface (cross-section) diameter of the rod-shaped portion is configured to be x.
That is, it becomes the same length as the short axis length x of the ellipse in the above embodiment.

Further, the adjustment pieces 12d and 12d according to the present example are substantially rectangular flat plates.
The adjustment pieces 12d and 12d are arranged at point-symmetric positions with respect to the axis center.
And the thickness of the adjustment piece 12d is comprised so that it may become (yx) / 2.
That is, in the state where the two adjustment pieces 12d and 12d are arranged, the distance between the outer surfaces of both the adjustment pieces 12d and 12d is configured to be y.
Therefore, it becomes the same length as the major axis length y of the ellipse in the above embodiment.
As a result, it is possible to form the same dimensions as the major axis length y and minor axis length x of the ellipse of the above embodiment, and similarly, it is possible to expand the joint width by changing the contact portion by rotation. Become.
If comprised in this way, it is not necessary to process the member of a cross-sectional ellipse, and the same function can be exhibited easily by adjustment piece 12d, 12d.

(Third modification)
Next, FIG. 8 shows a third modified example.
In the joint width adjusting jig 1 according to the third modified example, the shape of the adjusting unit 12 of the above embodiment is modified.
The adjustment unit 12 according to this example includes an attachment rod-like portion 12e and an adjustment block 12f.
The attachment rod-shaped portion 12 e is a rod-shaped body that extends from the central portion of one long side of the force acting portion 11.
In this example, a rod-shaped body having a circular cross-sectional shape is used, but the cross-sectional shape is not particularly limited and may be any shape such as an ellipse, a rectangle, or a polygon.

In addition, the adjustment block 12f according to this example is a substantially elliptical columnar block, and a mounting rod-like portion insertion hole 121 is formed in the central portion axial direction (direction passing through the central portions of both bottom surfaces). .
The free end side of the mounting rod-shaped portion 12e is fitted into the mounting rod-shaped portion insertion hole 121.
The bottom (cross-sectional) shape of the adjustment block 12f is configured to have the dimensions shown in FIG. That is, it has the same dimensions as the short axis length x and the long axis length y of the bottom surface (cross section) substantially elliptical.
Then, by attaching the adjustment block 12f to the attachment rod-like portion 12e, the diameter of the attachment rod-like portion 12e extending in the same direction as the long axis of the adjustment block 12f extends in the same manner as in the first modification. It is comprised so that it may become smaller than the major axis length y.
Therefore, as in the first modification, joint adjustment can be reliably performed, and damage to the exterior material P2 can be effectively prevented.
In addition to the effect, in this example, the adjustment block 12f can be an attachment method, so that it can be easily replaced and can be changed to various variations.
