Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fixing tool for fixing a formwork that connects the formwork and the formwork scaffold in the formwork construction and repairs the formwork.

[0002]

[Prior art]

 In the formwork construction, the formwork (horizontal unevenness of the formwork) is corrected by connecting the formwork and the formwork scaffolding and adjusting the interval between the formwork and the external scaffolding. Therefore, in the past, a straightening fixture as shown in FIG. 3 has been used.

In FIG. 3, the conventional fixing fixture includes a turnbuckle 50, chains 51 and 52, and a jack 53, and the turnbuckle 50 and the chains 51 and 52 connect the form A to the form scaffold B. The mold A is pushed by the jack 53 in a direction away from the mold scaffold B.

That is, hooks 54 a and 55 a are formed at the tips of the screw shafts 54 and 55 of the turnbuckle 50, and the hook 54 a of one screw shaft 54 and the building frame member B 1 on the outside of the form scaffold B are chained. 51, the hook 55a of the other screw shaft 55 and the horizontal material A1 of the form A are connected by a chain 52, and the main body of the turnbuckle 50 is rotated to form the form via the chains 51 and 52. A can be moved closer to the formwork scaffold B.

On the other hand, the jack 53 is arranged between the lateral material A1 of the form A and the building frame member B2 on the form side of the form scaffold B, and the jack 53 is extended to form the form. A can be moved away from the formwork scaffold B.

[0006]

However, the above-described conventional fixing fixture has the following problems.

(1) Since the turnbuckle 50 and the chains 51 and 52 are located on the scaffold passage of the formwork scaffold B, the passage cannot be secured, which hinders scaffolding work.

(2) Since the member for pulling the formwork and the member for pressing the formwork are different members, and adjustment work is required for each of them, the re-working work takes time.

(3) Since many members are used, it takes time and effort to carry in and out the members, and the cost of the fixing metal fitting increases.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to secure a scaffold passage without a member being positioned on the scaffold passage of the formwork scaffold, and to provide a simple simple structure. It is an object of the present invention to provide a fixing tool for fixing a formwork, which can be performed by a single member and can be easily and promptly performed.

[0011]

[Means for Solving the Problems]

 This invention relates to a turnbuckle and a turnbuckle of the turnbuckle in a straightening fixing metal fitting that corrects the formwork by connecting the formwork and the formwork scaffolding and adjusting the distance between the formwork and the formwork scaffolding. A clamp that is attached to the tip of one of the screw shafts and holds a member on the formwork side of the formwork scaffold (for example, a building frame member of the frame scaffolding), and a clamp that is attached to the other end of the screw shaft of the turnbuckle. It is composed of a locking member that is locked to the flap material.

[0012]

[Action]

 In the above configuration, the locking member at one end of the turnbuckle is attached to the flap material of the formwork from above and locked, and the clamp at the other end is attached to the formwork side member of the formwork scaffold. Fix it. When the main body of the turnbuckle is rotated, the clamp and the locking member are moved toward and away from each other by the screw shafts having the opposite threads, and the mold is pushed and pulled with respect to the mold scaffold. . A large number of such fixing fixtures are arranged at appropriate intervals in the horizontal direction, and the unevenness in the horizontal direction of the formwork is corrected.

[0013]

【Example】

 The present invention will be described below with reference to an illustrated embodiment. FIG. 1 is a front view showing a straightening fixing metal fitting according to the present invention, and FIG. 2 is a perspective view showing a usage state thereof.

As shown in FIG. 1, the straightening fixing metal fitting 1 according to the present invention comprises a turnbuckle 2, a clamp 3, and a U-shaped locking member 4. The clamp 3 is a normally used clamp that can detachably hold the building frame member B2 of the form scaffold (frame scaffold) B, and the holding base 3a is attached to the tip of the screw shaft 5 of the turnbuckle 2. It is rotatably attached.

The locking member 4 is formed by bending both sides of the plate material into a groove-shaped transverse cross section, which is formed into a U shape composed of a base piece 4a and a pair of protruding pieces 4b, and is formed on the upper and lower sides of the form A. It is configured so that it can be engaged with at least one single pipe of the two-tiered flat member (single pipe) A1 from the upper side and prevent the horizontal separation from occurring.

The tip of the other screw shaft 6 of the turnbuckle 2 is fixed by welding or rotatably attached to the outer surface of the one protruding piece 4b of the locking member 4.

In the structure as described above, the locking member 4 is mounted on the horizontal material A1 of the form A from above and locked, and the clamp 3 is the building frame member B2 of the form scaffold B on the form side. And clamp it by tightening the clamp bolts and nuts. Then, the main body 2a of the turnbuckle 2 is rotated to move the screw shafts 5 and 6 which are reverse-threaded to each other toward and away from each other.

As a result, the clamp 3 and the locking member 4 move in a direction in which they approach each other or in a direction in which they separate from each other, and the mold A is pushed and pulled with respect to the mold scaffold B. Such a re-fixing fixture 1 is arranged for each building frame member of the form scaffold B, and a large number of re-fixing fixtures 1 horizontally corrects the form A.

The re-fixing fixture 1 is arranged between the formwork A and the formwork scaffold B, and no member is arranged on the scaffold passage of the formwork scaffold B. It doesn't get in the way. Also, since the member is a single member, it can be easily carried in and out of the work place, and at the same time the formwork can be pushed and pulled by simply rotating the turnbuckle body. be able to.

[0020]

[Effect of device]

 As described above, the fixing tool according to the present invention has a clamp for holding a member on the formwork side of the formwork scaffold at one end of the turnbuckle, and a clamp for holding the formwork flap material at the other end. Since the stop member is provided, the following effects are obtained.

(1) Since the fixing metal member is not located on the scaffold passage of the formwork scaffold as in the conventional art, the scaffold passage can be secured and the scaffolding work can be performed without any trouble.

(2) The mold can be pushed and pulled by a single member, the re-passing work can be performed easily and quickly, and the work efficiency can be improved.

(3) Since it is a single member, it is possible to easily carry in and out the member at the work place and reduce the cost of the member.
