The goal is to improve work efficiency.

(Prior Art) Conventionally, a setting device for lifting a reinforcing bar buried in a foam concrete slab and setting it in a formwork has a pair of legs 2 as shown in FIG.
1, upper and lower fixing plates 22 and 23 are installed at a predetermined interval in the vertical direction, and a set rod insertion hole 24 is installed at a predetermined pitch at the longitudinal side end of each fixing plate 22 and 23. It consists of a setting frame A' having a hole in it, and a setting rod B' having a half-moon-shaped engagement member 26 fixed to the lower end of the narrow diameter part 25a of the different diameter rod 25, and a handle 27 attached to the upper end. An upper end engaging member 28 made of reinforcing bars arranged in a grid shape is fixed to the upper end of the reinforcing bar cage C′, and a lower end member 29 made of reinforcing bars arranged in a rectangular shape is fixed to the lower end.
After inserting the setting rod B' between the upper and lower end engaging members 28 and 29, the setting rod B' is rotated approximately 90 degrees to remove the setting frame A', the setting rod B', and the reinforcing bar C'. were integrated.

However, this setting device is extremely inefficient since it is necessary to manually rotate the setting rod B' one by one and fix it to the reinforcing bar C'.

In addition, the setting frame A' and the plurality of setting rods B' are assembled in advance, and the reinforcing bar C' is lifted up.
A set rod is attached to the engagement members 28 and 29 at the upper and lower ends.
Although there is a mechanized method for inserting B′ and then rotating and fixing setting rods B′, it is difficult to simultaneously fix many setting rods B′ to many reinforcing bars C′. Not only that, it was necessary to lift the reinforcing bar C', which was also inefficient.

(Structure of the Invention) In view of the above-mentioned drawbacks of the conventional reinforcing bar setting device, the present invention makes it possible to fix the setting bar to the reinforcing bar without rotating it, and to set it at a predetermined pitch. Each setting bar fixed to a large number of placed reinforcing bars can be fixed to the setting frame at the same time, thereby significantly improving the efficiency of reinforcing bar setting work.Examples will be explained below with reference to the attached drawings. do.

In addition, as shown in Figure 3, the reinforcing bar cage C buried in the foamed concrete slab is made of reinforcing bars set in a thick plate shape, and the reinforcing bars are set in the shape of a grid on the upper surface of both longitudinal ends. An engagement member 13 is attached, and engagement rings 14 made of an elastic material are attached to the lower surfaces of both ends. This engagement ring 14 is for engaging the spherical portion 11 of the setting rod B and fixing the setting rod B to the reinforcing bar C.

In addition, in Fig. 4, D is the formwork and M is the formwork D.
The mortar 15 and 16 injected therein represent the bottom plate and side plate of the form D, respectively.

(Action of the invention) Next, the action of the invention will be explained. As shown in FIG. 1, a large number of reinforcing bars C are arranged at equal intervals (equal to the pitch p),
Insert the setting rod B into the engagement member 13 on the upper surface of both ends of each reinforcing bar C, and insert the spherical part 1 at the lower end of the setting rod B into the engagement ring 14 on the lower surface of both ends.
1, the engagement ring 14 is pushed out and the spherical part 11 of the set rod B is inserted into the engagement ring 14, and they are firmly engaged, and the set rod is attached to both ends of the reinforcing bar C. B is fixed almost vertically.

Next, as shown in FIGS. 1 and 5,
The opening of the width direction groove 8a of each fixed plate 2, 3 and the opening of the longitudinal direction groove 9a of each slide plate 5, 6 are kept in a state that almost coincides with each other, and in this state, move the set frame A in the direction of arrow Q. The flanges 12 of each setting bar B are brought into contact with the upper surface of the lower fixing plate 3, and each setting bar B is moved to the upper and lower fixing plates 2,
3 into the depths of each width direction groove 8a. If the upper slide plate 5 is moved in the direction of arrow R in this state, the lower slide plate 6 will also move in the same direction, and as shown in FIG. Due to the peripheral edges of each groove 8a, 9a provided in the plates 2, 3 and each slide plate 5, 6,
A large number of setting rods B are simultaneously fixed to the setting frame A in a state where they are surrounded at two points in the axial direction and are immovable in both the radial and axial directions.

Next, when setting frame A is lifted, setting rod B
Since the flange portion 12 of the reinforcing bars C is in contact with the upper surface of the lower fixing plate 3, a large number of reinforcing bars C are suspended from the setting frame A via the setting rod B, and are lifted up as a unit. As shown in FIG. 4, when each leg 1 of the set frame A is placed on the upper end surface of both side plates 16 of the formwork D, a large number of reinforcing bars C are maintained at equal intervals within the formwork D. is set.

Next, mortar M is poured into the formwork D, and when the mortar M is semi-hardened, the setting frame A is momentarily pulled strongly upward to separate each setting bar B from the reinforcing bar C. Let it out and take it out.

By using the longitudinal grooves 9b, the intervals between the reinforcing bars C set within the formwork D can be varied.

(Effects of the Invention) According to the reinforcing bar cage setting device of the present invention, the setting bar and the reinforcing bar cage can be set by strongly pressing or pulling up, without rotating the setting bar as in conventional setting devices. It is possible to integrate or separate many setting bars and setting frames, and it is also possible to fix or separate a large number of setting bars and setting frames at the same time with a simple operation. It is possible to save labor in setting the basket, and also to significantly shorten the setting time, thereby improving work efficiency.

Furthermore, according to the present invention, it is possible to set two types of reinforcing bars with different setting pitches using the same setting frame, and therefore the number of different setting frames that must be prepared in advance is halved. Not only is this extremely economical, but the storage space for the set frames within the factory can be reduced.
