Description

[Detailed Description of the Invention] This invention relates to a separator with a reinforcing bar holder for formwork that can hold vertical reinforcing bars, horizontal reinforcing bars, etc. by using the separator for maintaining space between forms.

Next, this invention will be explained in detail using illustrated examples.

Figures 1 to 5 show a first embodiment of this invention, in which male threaded portions 5 provided at both ends of a separator main body 4 made of a round metal bar are fitted with molded nuts made of a metal plate. The frame support member 1 is screwed together, and an annular stopper 6 is formed by extrusion on the separator main body 4 at a position adjacent to the inner end of the male threaded portion 5 by extrusion. The members 1 are engaged to form a formwork separator 2.

An annular groove 7 is formed in the separator body 4 by button roll processing at a position a certain distance inward from the formwork support member 1, and a holder body 8 made of a metal plate bent into a groove shape. One arm 9 is provided with a partially cut-out circular fitting portion 10 that fits into the annular groove 7 and a guiding slit 11 that opens the fitting portion 10 at the tip edge of the one arm 9. The width d1 of the guiding slit 11 on the fitting part side is equal to the diameter D of the arm fitting part in the annular groove 7.
The other arm 12 of the holder main body 8 has a partially cut-out circular fitting part 13 that fits into the cylindrical outer peripheral surface of the separator main body 4, and A guiding slit 14 for opening the fitting part 13 at the tip edge of the arm 12 is provided, and the width d2 of the guiding slit 14 on the fitting part side is equal to the diameter D2 of the cylindrical outer peripheral surface of the separator main body 4. In addition, the width of each guide sling N1, 14 gradually widens toward the tip edge of the arm 9° 120, and furthermore, in the middle part of the holder body 8, one fitting is provided. The reinforcing bar holder 3 is provided with a deformation slit 15 extending from a position close to the fitting part 10 to a position 1 near the other fitting part 13.

When the reinforcing bar holder 3 is fitted in a predetermined position in the longitudinal direction of the separator body 4 so as to be rotatable and not move in the longitudinal direction of the separator body 4, both arms 9 and 1 of the reinforcing bar holder 3 are fitted.
When the annular groove 7 and the cylindrical outer peripheral surface of the separator main body 4 are fitted into the guiding slits 11 and 14 in the separator main body 2, and then the intermediate part of the reinforcing bar holder 3 is strongly pressed toward the separator main body 4. , each guiding slit 1
1゜140 width is slightly expanded and deformation slit 1
The reinforcing bar holder 3 is elastically deformed by the separator body 4 so that the width of the fitting part 10 is slightly reduced.
When the fitting part 13 fits into the annular groove 7 of the separator main body 4 and the other fitting part 13 fits into the cylindrical outer peripheral surface of the separator main body 4, the elastic restoring force of the reinforcing bar holder 3 causes each guide The width of the slits 11 and 14 is slightly reduced, and the width d1 on the fitting part side of one of the guiding slits 11 becomes slightly smaller than the diameter D1 of the arm fitting part in the annular groove 7, and The width d2 of the fitting portion side that fits into the slot 14 is slightly smaller than the diameter D2 of the cylindrical outer peripheral surface of the separator main body 4.

The both sides of the annular groove γ in the groove width direction become locking parts for positioning the reinforcing bar holder and engage with both sides of the fitting part 10 in the arm 9 in the longitudinal direction of the separator body of the reinforcing bar holder 3. Prevent movement.

Therefore, the reinforcing bar holder 3 is rotatably held at a predetermined position of the separator body 40 so as not to move in the longitudinal direction of the separator body.

FIG. 6 shows the usage state of the separator with a reinforcing bar holder according to the first embodiment, in which the end of the separator main body 4 is inserted into the through hole 17 of the formwork 16, and
The inner surface of the formwork support member 1 is in contact with the outer surface of the formwork support member 1, and the formwork 1
Formwork fastener 18 is attached to the external threaded portion 5 protruding from the outer surface of 6.
are screwed together, and further reinforcing bars 19 such as vertical reinforcing bars or horizontal reinforcing bars are fitted into the grooves of the reinforcing bar holder 3, and both arms 9 and 12 of the reinforcing bar holder 3 are connected to the separator main body 4 as described above. It is rotatably locked at a predetermined position 4 of.

FIGS. 7 to 10 show a second embodiment of this invention, in which guide slings N1 and 14 are provided to open at one side edge of arms 9 and 12, respectively, and deformable The slit 15 is provided so as to open at the other side edge of the arm 9.degree. 12, but the other structure is the same as in the first embodiment.

11 and 12 show a third embodiment of this invention, in which a reinforcing bar holder 3 having a fitting portion 10.13 is constructed by bending one Q metal rod. However, the other configurations are the same as in the first embodiment.

When implementing this invention, the reinforcing bar holder 3 may have any shape other than that shown in the drawings, the material of the reinforcing bar holder may be plastic, and the shape of the formwork support member 1 may be As shown in FIGS. 13 and 14, any known structure and locking means may be adopted. As shown in FIGS. A stopper 21 may be provided on the separator body 4.

According to this invention, a rod-shaped separator main body 4 having a formwork support member 1 is provided with a locking part for positioning the reinforcing bar holder on the inside of the formwork support member 1.
is rotatably fitted into the separator main body 4 and engaged with the locking portion so as not to move in the longitudinal direction of the separator main body, so that the separator is used for maintaining the spacing between the formworks. 2 and the separator main body 40 of the separator, the reinforcing bar 19 can be held in a predetermined position by using the reinforcing bar holder 3 rotatably attached to a predetermined position. Since it is rotatably attached, it is possible to easily hold reinforcing bars 19 such as vertical reinforcing bars or horizontal reinforcing bars in any direction.
