BRIEF DESCRIPTION OF THE DRAWINGS FIG. The embodiment relates to the adjustment of the height of the manhole receiving frame, which has an annular frame 2 for receiving the lid 1 at the peripheral edge thereof, and places the frame 2 on a side block 5 forming a foundation on which the lid 1 is installed. Are mounted at required intervals and postures. Frame 2 has a flange-shaped section, the inner diameter and the inner diameter of Gawakatamari 5 of that is approximately the same diameter (Fig. 1).

An elastic member 6 is provided below the frame 2 for adjusting the height thereof. The elastic member 6 has a characteristic capable of elastically deforming and restoring depending on the presence or absence of a pressing force, and utilizes the deformation and restoring property for height adjustment. The illustrated elastic member 6 is made of a band-shaped metal material having elasticity and elasticity. Such a material is bent into a substantially V-shape or a U-shape so that the free ends 16 and 17 and the bent portion 18 of the bifurcated shape contact the lower end surface 3 of the frame 2 and the upper end surface 4 of the side mass 5. It is arranged and crushed to the extent that required dimensions are obtained by applying a vertical force to provide a support whose height can be adjusted.

Two types of elastic members 6 are prepared.
The first kind of elastic member 6-1 is used in a state where the V-shape is turned sideways, and one of the two pieces 16 and 17 of the V-shape is placed on the upper end surface 4 of the side mass 5 and the other. Supports the lower end surface 3 of the frame 2 (see FIGS. 2 and 4). That is, it is suitable for use in adjusting the height of a relatively low side by utilizing the elastic deformation of one of the V-shaped pieces. This elastic member 6-1 has two pieces 1
Through holes 10-1 and 10-2 are formed in oval or circular shapes respectively in 6 and 17, through which bolts 7 to be described later pass.
The bending R of the bent portion is set to several times the plate thickness t, whereby the compression height is 3 to 5 t, and fine adjustment at a low height is also possible.

At the position corresponding to the bottom, a bottom piece in contact with the upper end surface 4 of the side mass is provided at the bent portion 18, and the ends of the two pieces 16, 17 rising from the bent portion are bent outward to lower end surface of the frame 2. The slidable contact pieces 11, 11 are provided in a curved shape on 3 (see FIGS. 3 and 5). In the case of this example, V-shaped two pieces 1
Since the elastic deformations 6 and 17 are used, it is suitable for height adjustment on a relatively high side. Since the elastic member 6-2 is used upright, the through hole 10 may be formed at one place in the bottom piece. Note that the bending angle θ of the two pieces 16 and 17 of the elastic member 6-2 used upright may be as small as 30 degrees or less.

It is assumed that they are used in contact with each other.
The free end is the end 16 'of the upper piece 16 in the case of an inverted V shape,
In the case of a vertical V-shape, the contact pieces 11 are curved. This is because the elastic members 6-1 and 6-2 are made of metal, and when the elastic members 6-1 and 6-2 are similarly deformed via the metal frame 2, the resistance is small and it is easy. On the other hand, since the side lump 5 is made of concrete, it has a large resistance and is suitable for fixing the elastic members 6-1 and 6-2.

A bolt 7 is used for fixing the elastic members 6-1 and 6-2 and the frame 2 to the side block 5. The bolt 7 that has been conventionally used for fixing the frame 2 can be used as it is.
And screwed into the female screw hole 16 formed in the hole. The position and the number of the female screw holes 16 match the positions and the number of the bolt holes 8 formed in the flange portion of the frame, and the mounting positions of the elastic members 6-1 and 6-2 are selected according to the positions of the bolt holes. The posture of the frame 2 is determined. Reference numeral 19 denotes a washer used as appropriate.

A detent 12 is provided for stabilizing the elastic members 6-1 and 6-2. In the case of the embodiment, the detent 12
Has a recess formed in the lower end surface 3 of the frame 2 which contacts the elastic members 6-1 and 6-2 (FIG. 6). Such a detent 12 may be formed on the upper end surface 4 of the side lump, or may be formed on both surfaces 3, 4. It is preferable that the rotation stopper 12 composed of the concave portion is slightly wider than the width A of the elastic member 6-1 and the depth is set to be twice or more the thickness t of the elastic member 6-1.

In order to fill an annular space 20 between the frame 2 and the side lump 5 bolted on the side lump 5 via the elastic member 6 with a solidifying material 21 such as a quick-drying concrete mortar, Inner peripheral covering body 22 which is in close contact with the side block 5 and the inner peripheral surface of the frame 2
And the outer peripheral covering member 23 that is in close contact with the outer peripheral surface. These cover bodies 22 and 23 form a mold for filling the space 20 with the binder 21, and include a foamed resin material,
It is made of various synthetic resin materials and rubber materials. The outer peripheral covering body 23 of the embodiment is a rubber band ring prepared in advance to have a diameter suitable for the outer diameter of the side lump 5 and the frame body 2 and is elastically fitted. The inner peripheral covering body 22 is a band ring adjusted to a diameter adapted to the inner diameter of the frame body 2 or the side lump 5, and is set from the inside by bonding to form a mold.

In order to mount the frame 2 using the height adjusting device of the present invention, the elastic members 6-1 and 6-2 are required between the side block 5 and the frame 2 as described above. After several sets, the elastic members 6-1 and 6-2 in a specific direction are elastically deformed by retightening the nut 9, or the elastic member 6 is previously deformed to a necessary degree and then tightened by the nut 9, and the height on both sides is increased. h1 and h2 are adjusted (FIGS. 7, 8, and 9). At this time, if the nut 9 is excessively tightened, the nut 9 can be loosened to loosen the elastic member 6.
Since the restoration is performed with the elasticity of 1, 6-2, the heights h1, h2 can be easily adjusted not only to be lowered but also to be increased again.

Next, the inner peripheral cover 22 and the outer peripheral cover 23 are attached to the inner peripheral surface of the side lump 5 and the frame 2 by the above-described method, respectively, and the frame 2 and the side enclosed by them are attached. Concrete mortar is fixed to the annular space 20 between the mass 5 and the solidification material 2.
1 and consolidated together with the elastic member 6 (FIG. 1).
0). For filling the concrete mortar, the outer peripheral cover 23 is poured into a gap 24 formed by partially expanding the outer cover (FIG. 12), or a funnel 25 is used through a bolt hole 8 provided in the frame 2. The pouring method (FIG. 13) is employed. Then, the mold is released, and the height adjustment having the required inclination is completed (FIG. 11). Note that two or more elastic members 6 may be attached and mounted at one location.

[0015] Among the methods for filling the solidification material, in particular, with regard to the inner peripheral covering member 22, the tire tube is applied to the inner side, and the inner peripheral covering member 22 is pushed outward by utilizing the inflation pressure, and is fixed. can do. When filling the consolidated material 21, a filling tool can be used instead of the funnel 25. In order to prevent the lower portion of the outer cover 23 from opening due to the weight of the solidifying material 21 to be filled, the lower periphery of the cover is fastened with a tightening belt.

[0016]

Since the present invention is constructed and operates as described above, the elastic members 6-1 and 6-2 interposed between the side block 5 and the frame 2 are deformed under pressure. , The height of the frame 2 can be freely set. In particular, the elastic member 6-1 supporting the frame 2 is suitable for adjusting the lower side, and the elastic member 6-
2 is suitable for adjustment on the high side, so adjust on either side
The amount of adjustment is small, and it is impossible for the elastic members 6-1 and 6-2.
No force is applied, and rotation is prevented by the rotation stopper 12.
