Description

  The present invention relates to a misplacement correcting tool and a misplacement correcting method for correcting a misplacement of a board joint portion in a wall formwork.

Conventionally, a reinforced concrete structure is constructed by surrounding a rebar with a wooden formwork, pouring ready-mixed concrete into the formwork, and removing the formwork after the concrete has hardened.
However, the slats of these molds are prone to warpage and level differences due to displacement at the connecting points, and there is an error in the dimensions of the timbers and ends, especially the square members, that support the pressure applied to the slats, which makes a mistake. Cheap. As a result, if the concrete wall is misplaced, it is not aesthetically pleasing and may hinder the next process, requiring repairs such as grinding with a grinder or thick coating with mortar. Since these processes require considerable time and effort, it is conceivable to adopt a tongue structure in which unevenness is provided at the end of the dam plate to eliminate the deviation of the joint. However, when cutting a standardized board in accordance with the size of each part of the structure, there are many cases where the tongue structure is not utilized.
Therefore, perforations are made in the panel (skin plate), a nail anchor is inserted therein, a pin is driven into the inside, and the tip is expanded and fixed temporarily, and the concrete form clamp body is connected to the nail anchor, Proposed a method to eliminate the mistakes by fitting the end washer and bringing it into contact with the end thick member, screwing the nut and tightening it, and pulling out the panel (slip plate) to contact the end thick member. (See Patent Document 2).
In addition, a corner frame having a space for inserting a hook and a groove having a trapezoidal cross section formed on the inner surface thereof, or each mold having a fixed frame, is formed on the back of each of the corner mold and the horizontal mold. A method has been proposed in which a hook that is rotatable by a cam that is applied to one end of a horizontal main body is disposed and a clamp that is provided with a hook that is fixed to the other end is tightened (see Patent Document 1). .

However, the method described in Patent Document 1 is applied in the case where there is a mistake in the piling plate when the inner formwork is installed after the outer formwork of the wall formwork is installed and the reinforcing bars are arranged. Is difficult. In addition, the method described in Patent Document 2 requires a separate resin frame having a space for inserting a hook on the back surface of the dam plate and a groove having a trapezoidal cross section formed on the inner surface thereof, which is expensive. In addition, there is concern about the strength when placing concrete.
In view of the above circumstances, the present invention also corrects the difference between the slats generated when building the inner formwork after installing the outer formwork and placing the reinforcing bars among the wall formwork. The purpose is to provide an easy-to-correct miscorrecting tool.

The misalignment correcting tool of the present invention is a misconception that corrects the misalignment between adjacent slats by pulling the slats toward the front from the back side where the crosspieces are fixed to the slats of the formwork forming the concrete wall. It is a correction tool, and the band-shaped metal member is folded into a U-shape, and the main body part in which a laterally symmetrical horizontal part is formed by folding the end portion outwardly, and the bolt fitted in the main body part are searched. A locking member is provided that moves between a position approaching the main body portion and a position separating from the main body portion by locking a nail or a wood screw driven against the pier.
In this way, it is equipped with a main body part connected to a U-shaped horizontal part symmetrical to the U-shape, and a locking member that moves between a position approaching the main body part and a position separating from the main body part, thus correcting the misunderstanding It is possible to correct the mistake by pulling the pedestal toward the front by turning a bolt by locking a nail or a wood screw struck to the pedestal installed on the damming plate to the engaging part.
In that case, the main body portion is formed in a U shape by the upper seat portion and the pair of side portions, and the first screw hole is located in one of the side portions, and the first screw hole of the upper seat portion is closer to the first screw hole. A second screw hole is formed, a first flat member is fixed to the tip, a bolt with a first knob screwed into the first screw hole, and a second flat member is fixed to the tip. A bolt with a second knob screwed into the second screw hole, and the locking member is searched by the bolt with the second knob and freely between the second planar member and the upper seat portion. Can be moved to.
If it does in this way, a bolt with a 1st knob can be turned and a main-body part can be fixed to a crosspiece, and also a mistake correction work can be reliably and easily performed by turning a bolt with a 2nd knob.
Each of the first screw hole and the second screw hole is formed by joining a nut with which the first knob bolt or the second knob bolt is screwed to the outer surface of the side portion or the upper seat portion. It is preferable that
If the screw hole is formed by joining the nut, it is not necessary to cut the screw in the band-shaped metal member of the main body, and the thickness can be suppressed.
Further, the length of the side portion is longer than the height of the pier, and the difference between the length of the side portion and the height of the pier is set to be shorter than the length of the bolt with the second knob. When the second knob bolt is turned in one direction, the second planar member comes into contact with the crosspiece, and when the second knob bolt is turned in the other direction, the locking member is Is preferably in contact with the upper seat part, and the length of the upper seat part is longer than the width of the two adjacent piers, and the difference between the length of the upper seat part and the width of the two adjacent piers Is set to be shorter than the length of the first knob bolt, and when the first knob bolt is rotated in one direction, the first planar member comes into contact with the pier, When the first knob bolt is turned in the other direction, the first planar member is It is preferred to contact the serial side site.
If it is set as such a dimension, a main-body part can be reliably fixed to a crosspiece, and the dam plate and the crosspiece which have produced the mistake can be reliably pulled near.
Here, it is preferable that a grip portion for gripping the main body portion is installed on an outer surface of the side portion on a side different from the side portion where the first screw hole is formed.
If such a gripping portion is provided, it is easy to lock a nail driven into any of the two piers with a locking member, and it is also easy to carry a miscorrecting tool. It is.

The miscorrection correction method of the present invention is a miscorrection correction method for correcting the misunderstanding of the siding plate from the back side where the crosspieces are installed on the slab of the formwork forming the concrete wall, and corrects the misunderstanding. A first step in which a nail or a wood screw is driven at a predetermined position of the pier where the misalignment is corrected by drawing it toward the front of each of the piers installed on each of the dams, and the belt-shaped metal member is folded into a U-shape. In addition, the body portion in which the side portion is bent outward and a horizontal portion symmetrical to the left and right is formed, and the bolt fitted in the body portion are searched, and the position approaching the body portion is separated from the body portion. A misplacement correction tool having a locking member that moves between positions is arranged so as to press against each of the dams, while the nail or the wood screw driven in the above step is engaged with the locking member. The second step to stop and
The main body is fixed to the pier, the bolt is turned in a predetermined direction, and the locking member is moved closer to the main body, and the pier is moved until the horizontal portions abut each of the dams. And a third step of drawing.
If such a method is used, anyone can correct mistakes alone by driving a nail or the like into a pier to correct the mistake and operating a simple tool and the tool.
In that case, the third step may include a step of fixing the drawn pier and the pier adjacent to the pier with a nail, and removing the mistake correcting tool from the pier, thereby correcting the mistake. It is easy to reuse tools.

The miscorrecting tool of the present invention has a simple structure, and anyone can easily perform correction work from the back side of the template where the misunderstanding has occurred. In addition, according to the miscorrecting method of the present invention, if a nail or the like is driven into the pier installed on the back side of the misaligned template, the correction can be reliably performed using a correction tool having a simple structure. By fixing with a nail or the like after correction, the tool can be reused.

Below, embodiment of the miscorrecting tool of this invention is described.
1-4 is a figure which shows the miscorrecting tool of this embodiment, FIG. 1 is the figure which looked at the front from diagonally upward, FIG. 2 is the figure which looked at the back from diagonally upward, FIG.3 and FIG. 4 is a view of the left and right side surfaces as viewed obliquely from above.
The misalignment correcting tool 1 of the present embodiment shown in FIGS. 1 to 4 includes a main body 2 in which a band-shaped metal member is bent into a U-shape, and both ends thereof are folded outward, and a first planar member 6 is fixed to the tip. The first knob-equipped bolt 3, the second knob-equipped bolt 4 with the second planar member 7 fixed to the tip, and the second knob-equipped bolt 4 are searched and the nail placed in the pier is locked. And a movable locking member 5.
In the miscorrecting tool 1 of the present embodiment, a rod-shaped grip 9 is provided on the outer surface of the main body 2, but the grip 9 need not necessarily be provided.

The main body 2 is a bilaterally symmetric shape formed by folding the upper part 2a and the pair of side parts 2b formed by bending a band-shaped metal member into a U shape, and the side parts 2b. It has a horizontal part 2c. A hole through which the first knob bolt 3 is searched is provided in any one of the side portions 2b, and a nut 8 for screwing the first knob bolt 3 to the outer surface at the same position as the hole is provided. The first screw holes 2d are formed by welding or adhesion.
Further, a hole through which the second knob bolt 4 searches is provided at a position near the side portion 2b where the first screw hole 2d is formed in the upper seat portion 2a, and a second knob is attached to the outer surface at the same position as the hole. A nut 8 for screwing the bolt 4 is welded or bonded to form a second screw hole 2e.
Further, a rod-shaped grip 9 that grips the main body 2 is fixed to the outer surface of the side 2b opposite to the side 2b where the first screw hole 2d is formed by welding or bonding.
And the length of the upper seat part 2a is larger than the width of two adjacent piers, and the difference is set to be shorter than the length of the bolt 3 with the first knob. Therefore, when the first knob bolt 3 is turned in one direction, the first flat member 6 comes into contact with one side of the pier, and when the first knob bolt 3 is turned in the other direction, the first flat member 6 is on the side. It contacts the part 2b.
Moreover, the length of the side part 2b is longer than the height of the crosspiece, and the difference is set to be shorter than the length of the bolt 4 with the second knob. Accordingly, when the second knob bolt 4 is turned in one direction, the second planar member 7 comes into contact with the crosspiece, and when the second knob bolt 4 is turned in the other direction, the locking member 5 is moved to the upper seat portion 2a. Abut.

Here, the main body 2 of the present embodiment has a U-shape having an upper portion 2a having a length of about 62 mm by bending a band-shaped metal member having a width of 30 mm, a length of about 250 mm, and a thickness of about 2 to 3 mm. Each side part 2b having a length of approximately 60 mm and a horizontal part 2c having a length of approximately 30 mm are formed symmetrically with each other.
The first screw hole 2d is formed at a position approximately 25 mm from the horizontal part 2c, and the second screw hole 2e is formed at a position 15 mm to 17 mm from the side part 2b provided with the first screw hole 2d.
However, the dimensions of the main body 2 are merely examples, and are not necessarily limited to these dimensions.

The first knob-equipped bolt 3 and the first knob-equipped bolt 4 are obtained by fixing a knob (knob) to the head, and the shape of the knob may be any of a triangle, a circle, a plus, and a polygon. Moreover, although it is preferable to use a bolt with a total screw diameter of 4 mm to 6 mm and a length of 30 mm to 50 mm, it is not necessarily limited to this dimension.
And the 1st plane member 6 and the 2nd plane member 7 are plate-shaped small pieces, The shape may be a rectangle, a circle | round | yen, or a polygon, but it may be in the 1st screw hole 2d or the 2nd screw hole 2e. The first bolt 3 with the knob or the bolt 4 with the second knob 4 in the screwed state is firmly fixed by welding or bonding.

The first planar member 6 is used for preventing the first knob bolt 3 from coming out of the first screw hole 2d and for pressing the pedestal to fix the main body 2 to the pedestal.
Further, the second flat member 7 prevents the second knob bolt 4 from coming out of the second screw hole 2e, and when the locking member 5 is pulled toward the near side when the locking member 5 locking the nail is pulled forward. It is used to prevent it from coming off from the 2 knob bolt 4.
Here, a rectangular metal piece of 15 mm × 15 mm is used for the first planar member 6 of this embodiment, and a rectangular metal piece of 13 mm × 13 mm is used for the second planar member 7. The dimensions are examples, and are not necessarily limited to these.

Further, the locking member 5 is a member for locking a nail placed on a pier attached to a slat that corrects a mistake, and a hole through which the second bolt 4 with a knob is searched (shown in the figure). And a notch portion 5b for locking only the head of the nail so that the second knob bolt 4 can be freely moved between the upper seat portion 2a searched for and the second planar member 7. Is installed. Accordingly, by turning the second knob bolt 4, the second flat member 7 moves forward, and the piercing pierced nail is pulled forward, thereby correcting the mistake.
The locking member 5 of the present embodiment has a keyhole-shaped notch portion in which only a nail head is locked to one short side of a rectangular metal member having a thickness of 3 mm to 4 mm and a size of 16 mm × 38 mm. 5b is formed. However, the shape and dimensions are examples, and are not necessarily limited to these.

The grip portion 9 is used when the operator locks the locking member 5 on the nail or makes each horizontal portion 2c abut against the dam plate, and is a side portion provided with the first screw hole 2d. A bar-shaped body parallel to the side part 2b different from the part 2b is installed by bonding or welding, and at least two thirds of the total length of the bar-shaped body protrudes to the front side of the upper part 2a.
The grip portion 9 of the present embodiment is a resin rod-like body having a length of 210 mm and an outer diameter of 10 mm and a rounded knob attached to the tip, but is not necessarily limited thereto.

Next, an embodiment of the miscorrecting method according to the present invention will be described.
Since the mistake correction tool used in the present embodiment is the same as that described with reference to FIGS. 1 to 4, the redundant description of the mistake correction tool is omitted.
5 and 6 are views showing the back side of the formwork in which nails are nailed to the pier, FIG. 5 is a front view, and FIG. 6 is a plan view.
As shown in FIG. 5 and FIG. 6, when the siding board 10 to which the pier 11 is attached is installed, the slats 10 that are combined on the surface of the pier 11 due to, for example, the height of the pier 11 are different from each other. Deviation occurs. Therefore, in the first step of the present embodiment, the nail 20 is struck against the plinth 11 of the plinth 10 that needs to be pulled to the front in order to correct the mistake. However, it is not always necessary to use the nail 20 to hit the pier 11, and a wood screw with a head may be used.

7 and 8 are diagrams showing a second process until the main body is fixed to two adjacent piers by holding the grip portion of the miscorrecting tool by hand, and FIG. FIG. 8 is a diagram showing a state immediately before attaching a miscorrecting tool to the pier, and FIG. 8 is a diagram showing a state in which the main body is fixed to two adjacent piers.
As shown in FIG. 7, the vertical position of the upper seat part 2 a is changed so that the position of the nail 20 struck on the pier 11 and the position of the second knob-attached bolt 4 are matched. That is, as shown in FIG. 6, when the nail 20 is hit on the right pier 11 of the two piers 11, the first knob bolt 4 is on the right side, the grip 9 is on the left side, and the upper seat The grip 9 is supported with the left hand so that the part 2a is horizontal. At that time, the notch 5b of the locking member 5 faces downward so that the nail 20 can be easily locked, and protrudes from the upper seat part 2a when viewed from the front. However, the notch 5b does not necessarily have to face downward, and may protrude upward from the upper seat part 2a.
When the nail 20 is struck on the left pier 11 of the two piers 11, the first knob bolt 4 is on the left, the grip 9 is on the right, and the upper seat 2a is horizontal. In this way, the grip 9 is supported with the right hand.
As shown in FIG. 8, the nail is locked by the locking member 5 of the miscorrecting tool 1, and the two adjacent piers 11 are sandwiched so that the horizontal portion 2 a abuts against the dam 10.

In the third step, in FIG. 8, the first knob bolt 3 is tightened to fix the main body 2 to the crosspiece 11 wood.
Then, the second knob-equipped bolt 4 is turned to draw the locking member 5 locked with the nail 20 toward the front, and it is confirmed that each of the horizontal portions 2c abuts against the respective slats 10 to correct the mistake. .
When the misalignment is corrected, the two adjacent piers 11 are fixed with long nails 21.
Thus, if two adjacent piers are fixed with a long nail, the miscorrecting tool 1 of this embodiment can be removed and another misplaced part can be corrected.
However, concrete may be placed on the formwork while the misalignment correcting tool 1 of the present embodiment is installed without fixing the two adjacent piers 11 with the long nails 21.

It can be used to correct misalignment of the built-in formwork and also to correct misalignment between installed panels.
