Description

[Detailed description of the invention] This invention relates to an anchor box fixing device for attaching an anchor bolt to a foundation.

When installing machinery on a concrete foundation or the like in a factory, a large number of anchor bolts are used, so it is necessary to accurately embed the anchor box in advance during foundation construction.

This anchor box was fixed using the method shown in Figure 1 or Figure 2.

The fixing method shown in FIG. 1 involves fixing the anchor box a with nails d or the like when square pieces are placed on the finished concrete surface e. In this case, since the lower part is free, there is a drawback that lateral vibration occurs when the concrete is poured.

In order to prevent this lateral vibration, the method shown in Figure 2 fixes the anchor box a between the finished concrete surface and the existing waste concrete surface f, and fixes the square timbers b) and anchor box a with nails d, etc. do.

However, with this method, after the concrete has cured, it is necessary to pour concrete again to the design depth of the anchor box, which increases the number of man-hours.

The anchor box fixing device of this invention solves the problems mentioned above. ■ Improved anchor centering accuracy ■ Simplified anchor box finger attachment ■ Prevents lateral vibration during concrete pouring ■ Anchor box structure Prevents strength loss of objects.

■ On-site man-hours reduced by 9 The purpose is to

This invention will be explained below based on illustrated embodiments (FIGS. 3 to 9).

This anchor box fixing device 1 is composed of an upper fixing device 3 shown in FIGS. 3 and 4 and a lower fixing device 6 shown in FIGS. 5 and 6.

The upper fixing device 3 is an anchor box 2 made of hard paper or the like.
an upper fixed frame 4 for positioning the upper part of the frame, and an upper frame support member 5 for supporting the upper fixed frame 4 at a predetermined position with a basic reinforcement amount.
It consists of

The upper fixing frame 4 matches the shape of the anchor box 2, and is usually a ring-shaped frame.

As the upper frame support member 5, a wire or the like is suitable as a simple member, and by attaching a plurality of wires to the upper fixed frame 4 and connecting the other end to the foundation reinforcement 9, the fixed frame 4 can be fixed. It can be supported in place.

A lower fixing device 6 positions the lower part of the anchor box 2, and a plurality of lower frame supporting members 8 are provided erected between the lower fixing frame 7 and the waste concrete surface 10 to support the lower fixing frame 7.
It turns red.

The lower frame support member 8 is a narrow plate-like member, and its lower end is bent and fixed to the waste concrete surface 10 with nails or the like.

The lower fixed frame 7 is a frame body similar to the upper fixed frame 4, and is fixed at a predetermined position in the vertical direction between the lower support members 8,
If necessary, a plurality of lower fixing frames 7 are arranged at intervals.

7 and 8 show the upper fixed frame 4 and the lower fixed frame 7.
11 and 12 are shown, and various types of anchor boxes 2 can be fixed with the same anchor box fixing device 1.

That is, the anchor box 2 is prevented from moving in the vertical or lateral direction by the claw-shaped stopper 11 having a cut and bent inward or by the stopper 12 having an inward screw.

FIG. 9 shows how machinery is installed using the anchor box fixing device 1 of this invention.
The bolts 13 are fixed with grout or the like and used for installing machinery.

This invention consists of the above-mentioned structure and has a structure in which the anchor box is supported by an upper fixed frame and/or a plurality of lower fixed frames, so that even an anchor box made of paper or the like does not sway when concrete is poured.

In addition, since the anchor box is pressed by the anti-slip of the upper and lower fixing frames, vertical or lateral movement can be prevented, and by adjusting the anti-slip □, anchor boxes of various sizes can be fixed to the same anchor. This can be done using a box fixing device, and the slide can be easily adjusted to accommodate any height, including differences in the depth of concrete foundations.
