Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a separator device for connecting concrete formwork, and more particularly to a separator device in which two formwork separators are connected so that a formwork support interval can be freely adjusted.

[0002]

[Prior art]

 In the construction of walls and beams of concrete structures, the separator for holding the formwork at a predetermined interval forms a male screw that connects the form ties to both ends of a metal rod having a predetermined length, and The structure is such that a cone member that receives the form is attached to the positions near both ends of the metal rod.

[0003]

[Problems to be solved by the device]

 By the way, the thickness of the concrete structure has various dimensions. Therefore, it is necessary to prepare a separator having a length corresponding to the facing interval of the molds, which causes a problem that the number of kinds of separators becomes extremely large.

Therefore, an object of the present invention is to combine two separators to easily obtain separators having different lengths, reduce the number of kinds of separators, and increase the combined length. It is to provide a form separator device that can be checked at a glance.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention is composed of two separators and a connecting member that coaxially connects both separators, and one end is fixed to one separator. The member has a screw hole that opens at the other end along the axis, an axially long window hole that is provided in the peripheral wall so as to reach this screw hole, and the outer surface of the connecting member along the longitudinal direction of this hole. The other separator is provided with an external thread having a length to be screwed into the screw hole of the connecting member at the end of the other separator, and the other end connected to the other end by the length scale. This is a structure that displays the total length of the separator.

[0006]

[Action]

 Connect the two separators by screwing and connecting the other separator to the screw hole of the connecting member that connects the one separator to the one end, and adjust the screwing amount while observing the end of the other separator at the window hole. If the ends are aligned with the desired length scale, the mold support lengths of both the joined separators can be known at a glance.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in the figure, the separator device is composed of two separators 1 and 2 and a connecting member 3 that connects the separators 1 and 2 in a coaxial extension, and both separators 1 and 2 are connected to both ends of a metal rod 4. It has a structure in which male screws 5 are formed on both sides and cone members 6 are attached at positions near both ends, and the distance between the mold supporting surfaces of both side cone members 6 is the length of the separators 1 and 2. .

The connecting member 3 has a length of, for example, about 7 to 15 cm, has a circular cross section or a polygonal shaft having a diameter larger than that of the metal rod 4 of the separators 1 and 2, and extends along the axis. A screw hole 7 penetrates through, and a window hole 8 elongated in the axial direction is provided on the outer surface so as to communicate with the screw hole 7.

The screw hole 7 of the connecting member 3 is formed so that the male screws 5 of the separators 1 and 2 are screwed together, and a portion of the outer surface of the connecting member 3 along the longitudinal direction around the window hole 8. Is provided with a scale 9 for indicating the total length of the two separators 1 and 2 connected to each other and a number.

On the other hand, in order to connect the separator 1 and the connecting member 3, the male screw 5 of the separator 1 is screwed into one end of the screw hole 7 by a predetermined amount so as not to reach the portion of the window hole 8. The loosening prevention nut 10 screwed onto the screw 5 is tightened so as to come into pressure contact with the connection member 3 so as to be coaxially connected.

The male screw 5 on the other separator 2 is formed long to match the length of the connecting member 3, and by screwing this male screw 5 into the screw hole 7 from the other end side, the other separator 2 and the connecting member 3 are connected. The coaxial coupling is performed, and the locking nut 11 that is previously screwed onto the male screw 5 is tightened so as to press-contact with the end surface of the connecting member 3, whereby both are fixed.

If the other separator 2 is screwed into the screw hole 7, the position of the end of the male screw 5 can be visually confirmed by the portion of the window hole 8. Therefore, the other separator 2 and the connecting member 3 are screwed together. At the time of connection, if the screwing amount of the other separator 2 is set by aligning the end of the male screw 5 and the scale 9, the combined length of both separators 1 and 2 can be read.

That is, the scale 9 provided on the connecting member 3 indicates the distance between the cone members 6 at both ends of both the separators 1 and 2 joined by using the connecting member 3, and the other one is displayed. If the end of the male screw 5 is aligned with the required scale 9 when the separator 2 is screwed in, a separator with the required formwork support interval can be constructed, and the screwing amount of the male screw 5 and the screw hole 7 can be set. The form support interval can be adjusted within the range where

Therefore, by connecting two separators 1 and 2 having a specific length, the total length of both separators 1 and 2 plus the length generated by the connection with the connecting member 3 is added. It is possible to construct a separator of the above, and two separators 1 and 2 can provide a new separator having a long form supporting interval.

In the illustrated case, the one-side separator 1 and the connecting member 3 are connected by screws, but for example, the one-side separator 1 and the connecting member 3 may be connected by welding in a butted state. Further, the cone member 6 on the connection side of both separators 1 and 2 can be omitted.

The separator device of the present invention is configured as described above, and when the supporting spaces of the facing molds 21, 21 are wide as shown in FIG. 1, the two separators 1, 2 are joined together, Make up a long separator.

That is, after connecting the separator 1 and the connecting member 3 to each other, the male screw 5 of the other separator 2 is screwed into the screw hole 7, and the end of the male screw 5 is aligned with the scale 9 having a desired length. By setting the screwing amount in this way, both separators 1 and 2 can be connected through the connecting member 3 to form a separator having a required formwork support interval, and the separators can support the formwork 21 and 21. Then, if the form ties 22 and 22 are connected to both ends and tightened through the thick end pieces 23 and 23, concrete can be poured between the form frames 21 and 21.

The separator formed by combining the two separators 1 and 2 can be freely selected within a range in which the frame support interval is, for example, 7 to 15 cm by selecting the screwing amount of the screw hole 7 of the connecting member 3 and the male screw 5. The two separators 1 and 2 can be widely used, and the dimension of the frame supporting interval can be confirmed by the end of the male screw 5 and the scale 9, so that the frame can be supported with an accurate size.

[0020]

[Effect of device]

 As described above, according to the present invention, the two separators are joined by the connecting member and the joining length is adjustable, so that the two separators can form a separator with a long formwork support interval. In addition to being able to do so, it is possible to deal with a wide range of changes in the support interval.

Further, since the connecting member is provided with the window hole and the scale for indicating the length is provided on the outer surface, it is possible to visually confirm the mold support interval as well as the coupling of the separator, and the required mold can be confirmed. Support intervals can be set accurately. (Note) Form Tie is a registered trademark.
