DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flattening tool.

[0002]

2. Description of the Related Art As a flattening tool for correcting a column distortion, the present inventor has proposed:
Japanese Patent Laying-Open No. 9-268765 proposes a flattening tool (hereinafter referred to as a conventional example). This conventional example,
Provide a bar-shaped roofing body that can be installed obliquely between an upper member such as a beam erected above the column or above the column and a lower member such as a joist laid below the column or below the column. The flattening body is composed of two members, that is, an upper rod and a lower rod which is connected to the lower part of the upper rod so as to be separable via a telescopic mechanism.

In using this conventional example, for example, first, a hook provided on an upper portion of an upper rod is hooked and locked on an upper member, and then a lower portion of the lower rod is fixedly connected to a lower member.
Subsequently, the upper bar is expanded and contracted to connect the lower portion of the upper bar and the upper portion of the lower bar, and the connected upper bar and lower bar are obliquely disposed between the upper member and the lower member. Then, the lower rod is contracted and adjusted by the expansion and contraction mechanism, and the connected upper rod is pulled to cause the column to correct the distortion of the column.

By the way, in this conventional example, since the flattening body is composed of two members, the work of obliquely disposing the upper member and the lower member between the upper member and the lower member is less troublesome than that which has been proposed before. Although it is excellent in the epoch-making point that the property is good, when the lower rod is actually fixed to the lower member, the lower rod is inclined at an angle to the upper rod (the upper rod The upper member for fixing the lower member and the lower member for fixing the lower bar-shaped member must be aligned with each other, and in this state, the lower member must be nailed and fixed to the lower member while supporting the lower member. When the lower rod is removed from the lower member, the nail to be fixed must be pulled out (of course, the reverse operation must be performed when removing the flattened body).

Accordingly, the present inventor has focused on this type of flattening tool, and has completed a flattening tool that can be operated more easily and that can greatly improve the workability of the flattening operation.

[0006]

The gist of the present invention will be described with reference to the accompanying drawings.

A long rod-like member for correcting the distortion of the column 1 is provided with an upper fixing portion 4 provided on the upper portion, which can be fixed to the upper member 2 such as an upper portion of the column 1 or a beam erected on the upper portion of the column 1. The erecting body 3 is provided with an expansion / contraction mechanism 5 for adjusting the length of the erecting body 3 to extend and contract, and is detachably fitted to a lower member 6 such as a joist placed beneath the column 1 or below the column 1. A fitted engagement body 7 that can be engaged in a state is provided.
The first half 9 and the second half 10 pivotally attached to the first half 9 so as to be freely slidable. A biasing body 13 for biasing the two halves 9 and 10 therebetween is provided at a pivot portion of the lower member 6, and the fitted locking body 7 is sandwiched and locked while being fitted to the lower member 6. The first half 9 and the second half 10 are configured such that the sliding power of the sliding half 10 acts when the lifting member 3 is contracted and adjusted.
Characterized in that the pinching force is increased.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention (how to implement the invention) will be briefly described with reference to the drawings, showing the operational effects thereof.

According to the present invention, for example, the upper fixing part 4 of the flattening body 3 is fixed to the upper member 2 such as a beam erected on the upper part of the column 1, and then, the locked member 7 of the flattening body 3 is fixed to the column. 1 and a lower member 6 such as a joist disposed laterally below the column 1. Subsequently, the upright body 3 is contracted and adjusted by the telescopic mechanism 5 to cause the column 1 to correct the distortion of the column 1.

Therefore, for example, the flattening body 3 to be fixed to the lower member 6 is not positioned and fixed by a fixing tool such as a bolt or a nail, but is merely a first half 9 and a second half 9 relating to the to-be-locked body 7. The flattening body 3 can be easily positioned and fixed to the lower member 6 by pinching and locking the body 12 with an arbitrary position of the lower member 6, and the flattening body 3 is simply contracted. By adjusting, the first half 9 relating to the to-be-locked body 7 is adjusted.
That the pillar 1 can be firmly fixed to the lower member 6 at the same time as the work that causes the column 1, for example, the pinching force between the lower half 6 and the second half 10 can be increased to firmly clamp the lower member 6. In other words, the engagement operation of the engagement-locking member 7 with respect to the lower member 6 is reliably performed in a series of operations and a sequence of operations that cause the column 1 to be performed with a very simple operation. It is possible to perform a flattening work.

Further, since the first half 9 and the second half 10 relating to the to-be-locked body 7 are urged in a direction to be sandwiched by the urging body 13, the to-be-locked body 7 is simply moved downward. Since it is temporarily fixed only by being sandwiched between the members 6, the firm positioning of the fitted engagement member 7 with respect to the lower member 6 can be easily performed. Raising work can be performed.

The U-shaped plates 10a, 10 of the second half 10
Recesses 10a 'and 10b' are formed in the upper portions of the respective b. The recess 10a ', 10b' is intended to constitute an engagement portion 11,
The projections 17b and 18b of the locking body 12 are fitted and locked.

As shown in FIGS. 2 and 3, a spring as a biasing body 13 is provided at a pivotal connection between the first half 9 and the second half 10.

Accordingly, the lower portions of the halves 9, 10 are urged in the narrowing direction.

An abutting member 22 is provided below the first half 9 to abut against the lower member 6, and a lower abutment against the lower member 6 is provided below the second half 10. A member 23 is provided. Also,
The hooks 9a ', 9b' with sharp tips are formed on the inner surfaces of the lower portions of the U-shaped plates 9a, 9b at the lower portion of the first half 9. When the hooks 9a 'and 9b' are fitted to the lower member 6,
The outer surface of the lower member 6 is slightly hooked and locked.

Accordingly, when the lower member 6 is sandwiched by the engagement-and-locking member 7, the contact members 22, 23 abut against the lower member 6 in a plane, and the lower member 6 is not provided with a nail hole or the like. Both can be securely locked.

A description will be given of the use of the locking body 12 and the fitted locking body 7 relating to the lower fixing portion 8 described above.

A state in which the locking body 12 is mounted on a desired position below the flattening body 3 (second rod body 15), and the fitted locking body 7 is fitted on a desired position of the lower member 6. , And the locking body 12 is hooked and locked to the locking portion 11 of the fitted locking body 7,
In this state, when the raising body 3 is contracted and adjusted, the second half 10

(Direction), and firmly sandwiches the lower member 6. Therefore, the stronger the contraction adjustment of the flattening body 3, the greater the force for pinching the lower member 6 (fitting engagement action), and the engagement of the locking body 12 with the fitting locking body 7. The stop (locking action) is firm. In addition, as compared with the frame A, the erecting body 3 (the first rod 14 and the second rod 1
Even if 5) is long, the mounting position of the locking body 12 to the flattening body 3 (second rod 15) can be arbitrarily moved and arranged, so that the flattening differs depending on the working environment. Body 3
The fixing work can be performed without any trouble by moving and disposing the locking body 12 at a position corresponding to the length (required amount).

Therefore, in the present embodiment, for example,
Upper fixed part (hook part) 4 on the upper part of the first rod body 14 according to
Is hooked and locked at a desired position of the upper member 2 such as a beam erected on the upper part of the pillar 1, and then the lower fixing part 8 (locking body 12) of the lower part of the second rod 15 is attached to the lower part of the pillar 1. Fitted locking body 7 fitted and locked at a desired position of lower member 6 such as a laterally mounted joist
And installed at an angle between the frames A. Subsequently, the extension mechanism 14a
The first rod 14 is shrunk and adjusted to connect the lower part of the first rod 14 and the upper part of the second rod 15 (separating rod 21) to form a rod,
The flattening body 3 composed of the first rod body 14 and the second rod body 15 connected in a bar shape is arranged obliquely between the shaft sets A.

The handle rod 21a of the separation rod 21
The first rod 14 is contracted and adjusted by the expansion and contraction mechanism 5 by rotating the rod to cause the column 1 to correct the distortion of the column 1.

Accordingly, the first rod 14 is provided so as to be freely connected and separated.
And the second rod 15 are fixed to the upper member 2 and the lower member 6 of the shaft set A, respectively, and only by connecting the lower part of the first rod 14 and the upper part of the second rod 15, The body 14 and the second rod 15 can be arranged obliquely between the shaft sets A. In this state, the first rod 14 is pulled by the telescopic mechanism 5 only by rotating the handle bar 21a. Since the column 1 can be raised, the installation work and the removal work between the frames A can be easily performed. That is, in the present embodiment, for example, when the flattening body 3 is fixed to the lower member 6, the flattening body 3 is not fixed to the lower member 6 with bolts or nails while supporting the flattening body 3. By simply pinching and locking the first half 9 and the second half 12 of the body 7 in a state where the first half 9 and the second half 12 are fitted to an arbitrary position of the lower member 6, the fixing operation of the flattening body 3 to the lower member 6 can be performed. It can be easily performed, and the flattening body 3 can be fixed without damaging the lower member 6, and furthermore, the shrinkage of the flattening body 3 can be simply adjusted to adjust the first half body of the fitted engagement body 7. The pinching force between the lower half 9 and the second half 10 can be increased to firmly pinch the lower half 6, such that the column 1 can be firmly fixed to the lower half 6 at the same time as the operation of causing the column 1. That is to say, the fitted locking action of the fitted locked body 7 on the lower member 6 and the fitted locked body 7 It is possible to perform a good erecting operation by a very simple operation, for example, such that the hooking and locking action of the lower fixing portion 8 to the column 1 is firmly performed in a series of operations and the operation that causes the column 1. .

Also, if the lower fixing portion 8 (locking member 12) provided on the raising member 3 (second rod member 14) is mounted on the locking member 7 to be fitted by special mounting means. Instead, the lower fixing portion 8 may simply be hooked and locked to the locking portion 11 provided on the fitted locked body 7. Therefore, for example, the operator confirms how the lower fixing portion 8 is hooked on the locking portion 11. Thus, it is possible to perform a straightening operation much more quickly.

Further, since the engagement-locking member 7 is temporarily fixed only by being sandwiched by the lower member 6, the fixing member 7 is temporarily fixed by the urging force of the urging member 13, so that, for example, the connecting member 7 swings at the time of connection with the flattening member 3. For example, it is possible to easily mount the lower fixing portion 8, and it is possible to easily perform firm positioning of the fitted engagement member 7 with respect to the lower member 6. Raising work can be performed.

[0043]

Since the present invention is constructed as described above, the work of fixing and removing the flattening member to and from the lower member can be easily performed. For example, a flattering tool installed between a certain upper member and a lower member can be used. Conventionally proposed razor-raising tools, such as the ability to quickly move by simple work even when there is a need to move to another place and relocate it because it interferes with the installation work of the brace and the movement of the worker This is a very practical razor-making tool that can be operated very easily and the workability is dramatically improved.
