Abstract

PROBLEM TO BE SOLVED: To make the whole of a metal fitting smaller and lighter by mutually approaching and separating a pair of sandwiching members according to the thickness of a rising wall and fastening them through a fastener. SOLUTION: In the case of using a support receiving metal fitting, a fastener 9(a screw shaft part 13) is loosened to make sandwiching members 1, 2 turn into a state where they can mutually freely approach and separate within the range of a slot 7. Next, the sandwiching members 1, 2 are externally fittedly mounted on the upper end part of the rising wall. In a state where both the sandwiching members 1, 2 are mutually approached to sandwich the upper end part of the rising wall between both vertical plates 3, 4, the fastener 9 (a screw shaft part 13) is rotated in a fastening direction by utilizing a bolt head 14a protruding toward the upper end of the fastener 9 to mutually fix both the sandwiching members 1, 2. After this, the lower end of a support for supporting a concrete form on an upper floor is externally fitted on a vertical shaft part 10. Thus this support receiving metal fitting can be wholly composed smaller and lighter than a usual support receiving metal fitting to use a usual channel-type clamp which is composed in consideration of the maximum thickness of the rising wall, and moreover inexpensively executed.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.
Reference numeral 2 denotes a pair of holding members, which are vertical plate portions 3 and 4, respectively.
And horizontal plate portions 5 and 6 which are provided horizontally inward from the upper ends of the vertical plate portions 3 and 4 and overlap each other. The upper horizontal plate portion 5 connects the vertical plate portions 3 and 4 to each other. A long hole 7 long in the direction is provided, and a screw hole 8 is provided in the vicinity of the tip of the lower horizontal plate portion 6 at a position overlapping with the long hole 7.

Reference numeral 9 denotes a fastener, which is a vertical shaft portion 12 in which the upper end of a cylindrical body 10 having a diameter to which the lower end portion of the support can be fitted is closed by a cover plate 11, and concentrically from the lower end of the vertical shaft portion 12. And a screw shaft portion 13 projecting therefrom and screwing into the screw hole 8 via the elongated hole 7. The screw shaft portion 13 is composed of a bolt 14 fixed with the head portion 14a protruding above the lid plate 11, and when the horizontal plate portions 5 and 6 are fastened and fixed, the lower horizontal shaft portion is formed. The length does not protrude downward from the plate portion 6.

According to the above configuration, the fastener 9 (the screw shaft 1)
By relaxing 3), the interval between the vertical plates 3 and 4 of the sandwiching members 1 and 2 can be adjusted from the minimum LS to the maximum LL within the range of the long hole 7. Therefore, in use, the fastener 9 (screw shaft portion 13) is relaxed so that the two holding members 1 and 2 can move close to and away from each other within the range of the long hole 7, and the two holding members 1 and 2 can be moved. Then, as shown in FIG. 4, the external fitting is mounted on the upper end portion 15a of the rising wall 15. Then, the fastening member 9 (screw shaft portion 13) is protruded from the upper end of the fastening member 9 in a state where the holding members 1 and 2 are moved closer to each other and the upper end 15 a of the rising wall is held between the vertical plates 3 and 4. The two holding members 1 and 2 are fixed to each other by rotating using the head 14a in the fastening direction. Thereafter, the lower end of a support 17 for supporting a concrete formwork 16 on the upper floor is fitted to the vertical shaft 10 so that the support 17 is supported on the horizontal plates 5 and 6 of the sandwiching members 1 and 2. You can do it.

In the above embodiment, the bolt 14 (screw shaft 13) is rotatable relative to the vertical shaft 12 and can be removed without fixing the bolt 14 to the vertical shaft 12 (cover plate 11). It can be used in any condition.

The support receiving member shown in FIG. 5 is fixed upward from the position near the tip of the lower horizontal plate portion 6 among the horizontal plate portions 5 and 6 overlapping on the rising wall 15 of both the holding members 1 and 2. A fastener 2 comprising a projecting fixed screw shaft 20 and a nut portion 21 screwed into the fixed screw shaft 20 projecting through the long hole 7 provided in the horizontal plate portion 5 which is provided above.
2 is used. The nut part 21 is fixed to the lower end of the cylindrical body 10 constituting the vertical shaft part 12. In this case, since the cylindrical vertical shaft portion 12 must be directly rotated, the cylindrical body 10 can be provided with a through hole 23 for inserting a rotary operation tool or the like into the cylindrical body 10 as shown in the figure.

The support receiving member shown in FIG. 6 is provided with long holes 7 and 24 in both horizontal plate portions 5 and 6 overlapping on the rising wall 15 of the sandwiching members 1 and 2 and a lower horizontal plate. A guide groove 25 is formed on the lower side of the portion 6 by bending both left and right sides of the horizontal plate portion 6 downward and along the length direction of the long hole. Then, the guide groove 25
The upper and lower horizontal plates 5, 6 are movably engaged with the slots 7,
And a bolt 26 passing upward through the vertical shaft 1.
2 is provided on the nut 2 and screwed into the bolt 26
Is used.

A nut may be movably fitted in the guide groove 25, and a screw shaft portion screwed to the nut may be fixedly protruded from the lower end of the vertical shaft portion 12. Also,
As shown by phantom lines in FIG.
Disc springs 28 and spring washers for preventing loosening due to vibration or the like can be used in combination with 2, 27.

[0015]

As described above, according to the support receiving member of the present invention, the pair of holding members are moved toward and away from each other in accordance with the wall thickness of the rising wall and fastened by the fastener. Can be made smaller and lighter as a whole than those using a conventional U-shaped clamp configured assuming the maximum wall thickness of the device, and can be implemented at low cost.

In addition, even if the wall thickness is small, since the two holding members are merely fastened to each other with the fastener after the two holding members are moved closer to each other, the fastening operation can be performed easily and quickly, and the workability is improved. . Further, regardless of the wall thickness, there is no protrusion that largely protrudes laterally from the wall unlike the conventional case, so that the safety is improved as compared with the conventional product.

According to the configuration of the second aspect, it is not necessary to fix the screw shaft to the holding member side, and the fastener can be formed from two points of the vertical shaft portion where the lower end of the support fits and the screw shaft. Therefore, it can be implemented at a lower cost.

Further, according to the configuration of the third aspect, there is a possibility that the screw shaft portion of the fastener projects downward from the lower horizontal plate portion of the horizontal plate portions vertically overlapping the sandwiching members. Not
The thickness of the holding member can be reduced. further,
According to the configuration of the fourth aspect, the range of adjusting the distance between the vertical plate portions of both the holding members can be increased.
