Abstract

PURPOSE:To make it possible to set an outlet box with a simple structure by pushing the outlet box into a concrete wall up to a predetermined embedded position, overcoming a leaf spring by means of a die frame. CONSTITUTION:A setting unit for an outlet box 1 comprises a movable member 3 adapted to be coupled with the outlet box 1, a stationary member 4 supporting the movable member 3, and a leaf spring 5 urging the movable member 3 away from the stationary member 4. The outlet box 1 is pushed into a concrete wall up to a predetermined embedded position, overcoming the leaf spring 5 by means of a die frame 30. The outlet box 1 is set at the embedded position in the concrete wall while its opening surface 32 being closed by the die frame 30.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an outlet box setting tool.

Conventionally, when embedding an outlet box in a concrete wall, the outlet box is temporarily fixed between the formwork of the opposite pair, a hole is made in the formwork, and the hole (L rod is passed through the hole).
The tip of the rod is connected to an outlet box, pulled toward the formwork and set in a predetermined position, and then concrete is poured between the forms. Therefore, it was not easy to set the outlet box in a predetermined position.

In view of the above, it is an object of the present invention to provide an outlet box that can be extremely easily set by using spring force to set the outlet box in a predetermined position, and also has a simple configuration and is easy to manufacture. be.

The present invention will be specifically described below based on examples thereof.

The setting tool (2) of the outlet box (1) includes a movable member (3) to which the outlet box is connected, a fixed member (4) that movably supports the movable member, and a connection between these movable members and the fixed member. A plate spring (5) is provided between the movable members and urges the movable member away from the fixed member.

The out-knot box (1) is embedded in a concrete wall, and has a square box shape with an opening that looks into the wall surface.

The movable member (3) has a rectangular plate part (6), in which a part of the cut (7) is made to form an upright claw (8), and a part for the connecting bolt (9). A through hole αG is formed, and guide edges αD are formed on both side edges of the plate portion, which are bent at right angles from the through hole αG. The plate part (6) is fixed to the bottom of the box (1) by passing the claw (8) of the plate part through the hole α3 of the box and bending its tip to support the box.

The fixing member (4) includes a rectangular plate portion α4, and holes α9 and αθ are bored at the top and bottom of the plate portion. The bolt (9) passes through the hole αO of the movable member (3) and attaches the nut αθ to the member.
The movable member (8) can be moved to the fixed member (4) by passing the bolt (9) through the hole 09 of the fixed member (4) and screwing the nut αη onto its tip. Assemble to.

The plate spring (5) is a rectangular plate that is bent into an arc shape in its natural state, and has a notch α → formed in the center of both sides of the plate and a long hole bored near both ends. 09, and both ends ■ are bent.

This plate spring (5) is attached to the fixing member (4) via the pedestal (2).
), and in the notches αe, of these leaf springs and the base, there are claws (4) formed by inserting a cutting mill into the fixing member (4)
By bending and interlocking the parts (goods), the plate springs (5
) is fixed to the fixing member (4). The plate spring (5) has both ends in contact with the plate part (6) of the movable member (3), is guided by the guide edge Qυ of the movable member, and is connected to the plate spring (5) and the movable member (3). Maintain the join relationship normally.

The plate part (2) of the fixing member (4) has a joint part (to) which is raised in an arc shape with cuts (c) made at both upper and lower ends thereof,
Connecting rods (A) are passed through the holes of these joints, and the joints (C) are tightened to secure the connecting rods to the joints.

The connecting rod (goods) is connected with wire to the reinforcing bars (7) assembled in the shape of a cross. As a result, the outlet box (1) is set between the formworks (7) and 01) using the setting tool (2). The outlet box (1) is not pushed into the formwork ■ in its natural state (-), but protrudes outside the installation position of the formwork (7). When the box is placed against the opening surface (2) and pushed to a predetermined installation position, the opening surface of the box is closed by the formwork (1) and the box is set at the embedded position within the concrete wall.

Note that the thickness of concrete walls varies, so adjust the distance between the movable member (3) and the fixed member (4) by turning the nut αη around the bolt (9) to suit the thickness. .

The arc shape of the leaf spring (5) may be one in which straight lines extending in the horizontal direction are inserted at appropriate intervals and folded along the lines to form an arc shape as a whole. Figure A), one that is entirely curved (Figure D), or a trapezoid with both ends of a straight part bent (Figure C).
is used as appropriate. In the case shown in FIG. 9A, if a vertical line (b) perpendicular to the horizontal line (to) is inserted (see figure q, A'), the bending stiffness becomes even greater.

As described above, the present invention provides a plate spring (5) between the movable member (3) to which the outlet box (1) is connected and the fixed member (4) that supports the movable member, and ), the outlet box (1) is pushed into a predetermined embedded position in the concrete wall against the plate spring (5), making it extremely easy to set up the outlet box. In addition, the configuration of the setting tool is simple and easy to manufacture.
