DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a burying frame which is used by being multi-tiered in the ground to form, for example, a fire hydrant box, a water control valve box, a manhole and the like.

[0002]

2. Description of the Related Art Conventionally, this kind of buried frame is generally formed into a predetermined shape by concrete.

[0003]

However, in such a concrete burying frame B, the concrete input surface 10a is usually finished with a trowel as shown in FIG.
In addition to the poor finishing accuracy, the end face is likely to have a rough surface having a large number of irregularities 11a due to the influence of air bubbles in the concrete. Therefore, when the burying frames B having such poor end surface accuracy are stacked in multiple stages, rattling occurs at the joints between the burying frames B, and the stability is remarkably lacking. There was a great problem that the joint was damaged by the load.

In the case where there is a dimensional error in the burying frame B, it is necessary to adjust the height at the time of stacking.
Conventionally, means for thinning mortar or the like at the joint between the burying frames B has been adopted.

[0005] However, such an adjusting means requires a high level of skill and labor, which not only complicates the work on site but also makes fine adjustment of the height difficult because the burying frame B is heavy. There was a problem that it was very difficult to do.

SUMMARY OF THE INVENTION Therefore, the present invention has been made in order to solve the above-mentioned conventional problems, and it is intended to smooth or absorb a rough surface having irregularities so that a plurality of embedded surfaces can be stably formed without causing rattling. It is an object of the present invention to be able to stack frame bodies and to perform height adjustment uniformly and easily.

[0007]

That is, the present invention has been made to solve the above-mentioned problems by providing a thin base frame 5 and a thin connecting portion 6 having a step on the outer periphery of the base frame 5. The adjusting frame 4 comprising the thin protruding frame 7 integrally connected with the
Is fixed so as to cover at least one of the upper and lower surfaces along the step shape.

[0008]

According to the embedding frame A with the adjusting frame having the above-described configuration, even if the end surface of the embedding frame 1 is a rough surface having irregularities, the adjusting frame 4 is formed on the rough surface. By fixing, it is possible to secure the flatness, and it is possible to stack the buried frames in a stable state while maintaining a constant height without causing backlash between the burying frames.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a substantially cylindrical concrete burying frame formed by protruding flanges 2 on the upper and lower outer peripheral surfaces, respectively. I have.

An adjustment frame 4 is fixed to the lower surface of the burying frame 1 with an adhesive or the like so as to cover the entire surface along the step shape. The adjustment frame 4 is shown in FIGS. As shown in the figure, the base frame 5 comprises a base frame 5 and a ring-shaped projecting frame 7 having a step on the outer periphery of the base frame 5 and integrally connected by a connecting portion 6. Is formed to have a thickness of about 3 mm, and the connecting portion 6 is formed to be thinner. The adjustment frame 4 is formed of a material such as a metal, a synthetic resin, and rubber.

The present embodiment has the above configuration.
Such an embedding frame A with an adjustment frame is used by being stacked in multiple stages on the upper stage of another embedding frame 1 placed on the slab 9 as shown in FIG. 3, for example.

In this case, since the adjusting frames 4 are fixed to the lower surfaces of the burying frames 1 which are brought into contact with each other when they are stacked, the lower surfaces of the burying frames 1 are uneven. Even if it is formed into a rough surface having a flat surface, the flatness of the entire lower surface is uniformly ensured by the adjusting frame 4, so that the embedded frame A with the adjusting frame maintains a constant height without rattling. Thus, a large number of burying frames 1 can be stacked in a stable state.

If there is a dimensional error or the like in the burying frame 1, the height of the burying frame A with the adjusting frame itself is adjusted by, for example, appropriately adjusting the thickness of the adjusting frame 4. In particular, since the thickness of the adjustment frame 4 is set to be thin, there is an advantage that the adjustment frame 4 can be used for fine adjustment.

In the above embodiment, the adjusting frame 4 is fixed to the lower surface of the burying frame 1, but it may be fixed to the upper surface, depending on the condition of the upper and lower surfaces of the burying frame 1. It only has to be fixed.

On the lower surface of the base frame 5 and the projecting frame 7 of the adjusting frame 4, small projections 8 may be formed in the circumferential direction as shown in FIG. 4. In this case, the material of the adjusting frame 4 is made of synthetic resin. , Rubber, etc., the small projections 8 become more familiar and have a packing function even when the upper and lower surfaces of the embedding frame 1 are not well-finished and the irregularities 11 are severe. This ensures the close contact state.

The small projections 8 are provided on the lower surface in the circumferential direction. The small projections 8 may be provided on the upper surface, upper and lower surfaces of the adjustment frame 4, or may be provided in the radial direction. The form of the small projections 8 can be arbitrarily changed in design.

Further, the shape of the burying frame 1 is not limited to a substantially cylindrical shape as in the above-described embodiments, but may be formed, for example, in a rectangular, polygonal or rectangular cylindrical shape. 5, the shape of the adjustment frame 4 also changes. In short, the shape of the adjustment frame 4 only needs to be formed corresponding to the shape of the embedded frame 1 to be fixed.

Further, the thicknesses of the base frame 5 and the protruding frame 7 of the adjusting frame 4 can be changed as appropriate, and the specific shape and thickness of the connecting portion 6 also conform to the step shape of the burying frame. What is necessary is just to be formed in thin shape.

In addition, the means for fixing the buried frame 1 and the adjustment frame 4 can be freely changed in design within the range intended by the present invention.

[0021]

As described above, according to the present invention, at least one of the upper and lower surfaces of the burying frame body which comes into contact with each other when stacked is covered so as to cover the buried frame along the step shape. Because the frame is fixed, even if such upper and lower surfaces are formed with a rough surface having irregularities, the adjustment frame ensures uniform flatness of the entire joint portion, so that the space between the burying frame bodies can be secured. The particular advantage of being able to stack in a stable state while maintaining a constant height without causing rattling is achieved.

On the other hand, it is possible to finely adjust the height of the burying frame itself by appropriately adjusting the thickness of the adjustment frame to be fixed, thereby causing a slight dimensional error in the burying frame. Even if it does, there is a unique effect that it does not hinder the stacking work.
