JPH09132923A - Inclination adjustment device of manhole cover receiver frame upper surface - Google Patents

Abstract

PROBLEM TO BE SOLVED: To adjust inclination of an upper surface of a manhole cover receiver frame in an optional direction and at an optional angle by connecting an upper part constitutional body and a lower part constitutional body constituting the manhole cover receiver frame on a spherical surface. SOLUTION: A receiver frame A of a manhole cover 8 is constituted of an upper part constitutional body 1 and a lower part constitutional body 2, and the upper and lower constitutional bodies 1, 2 are made free to connect to each other on a spherical surface W. Thereafter, an upper surface of the upper part constitutional body 1 is inclined at an optional angle by using the spherical surface W. Thereafter, a screw rod 5 planted and provided on the lower part constitutional body 2 is inserted in an unloaded hole 4 provided on a flange 3 of the upper part constitutional body 1, and the upper part constitutional body 1 and the lower part constitutional body 2 are connected to each other by a seat plate 6 and a nut 7. Consequently, it is possible to match inclination of the upper surface of the manhole cover receiver frame A with inclination of a road surface by adjusting the inclination of the upper surface of the manhole cover receiver frame A from an optional direction and at an optional angle.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for adjusting the inclination of the upper surface of a manhole cover receiving frame of an underground structure.

[0002]

2. Description of the Related Art Conventionally, manhole cover receiving frames are used for underground structures,
For example, when installing on the side wall of a manhole for water and sewerage or on the upper surface of a sloping wall, a flat type adjustment ring for raising the manhole cover frame and the underground structure, and an inclination angle adjustment if necessary, in order to match the normal road surface. Although a taper type adjustment ring for use in insertion is inserted, since the taper type adjustment ring for adjusting the inclination angle is inclined only in one direction of a wedge shape, when it is matched with the inclination direction of the road surface, The work of rotating the adjustment ring was required.

Moreover, since the taper angle of this adjusting ring is fixed, only a rough adjustment can be made and a fine adjustment cannot be expected.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention is intended to provide a device for adjusting the inclination of the upper surface of the manhole cover receiving frame which can adjust the inclination angle in any direction.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a manhole cover receiving frame is composed of an upper structure and a lower structure, and the upper structure and the lower structure are In addition to joining them on a spherical surface, they are joined by a joining means.

[0006]

Since the upper structure and the lower structure are joined by the spherical surface, the upper surface of the upper structure can be inclined in any direction and at any angle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a first embodiment of the present invention, in which A is a manhole lid receiving frame composed of an upper structural body 1 and a lower structural body 2, and the upper structural body 1 and the lower structural body. It has a structure in which it is joined to the structural body 2 by a spherical surface W, a fool hole 4 is bored in the flange portion 3 of the upper structural body 1, and a screw rod 5 inserted in the fool hole 4 is formed in the lower structural body 2. Was planted,
The screw rod 5, the seat plate 6 and the nut 7 connect the upper structural body 1 and the lower structural body 2.

In the figure, 8 is a manhole cover, 9 is a manhole side block, and 10 is a flat type adjusting ring.

FIG. 2 shows a second embodiment of the present invention. The difference from the first embodiment shown in FIG. 1 is that the upper surface 1'and the lower surface are constructed with an opposite spherical surface W '. This is a point configured to join the bodies 2 '.

In both the first and second embodiments, the upper structure 1 (or 1 ') and the lower structure 2 (or 2') are spherical surfaces W.
Since it is joined by (or W '), the upper surface of the upper structure 1 (or 1') can be set at any angle in any direction, and the upper surface of the manhole cover receiving frame should match the inclination of the road surface. You can

[0011]

According to the present invention, the upper surface of the manhole cover receiving frame can be adjusted in any direction in any angle.
