Description

[0001] LINING FOAM ANCHOR [0002]

The present invention relates to a lining foam fastening apparatus, and more particularly, to a lining foam fastening apparatus that can fix a lining foam to place a lining foam for a tunnel construction on a loading box of a trailer.

In general, shotcrete is placed on the walls of excavated tunnels, a nonwoven fabric and a waterproof sheet are attached on the shotcrete, and a lining concrete is formed to complete the formation of a waterproof surface.

These lining concrete are usually constructed by molding rather than spraying. For this purpose, a lining foam is used which corresponds to the shape of the inner surface of the tunnel.

A commonly used lining foam is composed of a formwork forming an outer surface and a structure for supporting the formwork. The form is formed to correspond to the cross-sectional shape of the tunnel by a steel plate having a predetermined thickness, and a structure composed of "" "shaped steel and" H "shaped steel for supporting the form is formed below the form.

The construction of the lining concrete is carried out by moving the lining foam inside the tunnel. For this purpose, it is necessary to form a rail system for moving the lining foam on the bottom of the tunnel.

However, in order to form a rail system, a separate site work is required. When the lining foam is moved depending on the rail, sequential lining concrete work is inevitably carried out, and the construction period is prolonged.

The lining form is an expensive lending equipment, and the rental cost, which is increased due to the prolonged construction period, has a problem that it may affect the increase of the overall construction cost.

On the other hand, the background art described above is technical information acquired by the inventor for the derivation of the present invention or obtained in the derivation process of the present invention, and can not necessarily be a known technology disclosed to the general public before the application of the present invention .

An upper connection bundle connected to the lower portion of the upper supporting portion so as to be rotatable and connected to one side of the first connection frame or another side of the second connection frame so as to be rotatable;
An elastic part installed on the lower side of the upper connection bundle and reducing the vibration transmitted through the upper connection bundle using an elastic force;
A lower connection bundle installed below the elastic part and connected to one side of the second connection frame or another side of the first connection frame so as to be rotatable, on a surface opposed to the other vertical frame; And
And a lower support portion formed to be in the shape of "ㅗ" and rotatably connected to a lower portion of the lower connection bundle to support the lower connection bundle,
The elastic portion
A cylindrical portion formed in an empty cylindrical shape, a lower portion of the upper support portion being inserted through a through hole formed in the upper portion, and an upper portion of the lower support portion being inserted through a through hole formed in the lower portion;
An upper plate positioned above the inner space of the cylindrical portion, and a lower portion of the upper supporting portion being fixedly installed;
A lower plate spaced apart from a lower side of the upper plate and fixed to an upper portion of the lower support; And
And an elastic body inserted in a space between the upper plate and the lower plate to reduce vibrations between the upper plate and the lower plate using an elastic force.
[2] The apparatus of claim 1,
Further comprising: at least one vibration damping unit installed on the lower side of the support to absorb and reduce vibration transmitted through the support,
Wherein the vibration damping unit comprises:
An upper support plate supporting the lower side of the support and formed in the form of a rectangular flat plate;
Four upper vibration absorbers installed at lower corners of the upper support plate to absorb vibration transmitted from the lower clamp;
Four upper support frames each extending downward from the four upper vibration absorbing parts and supporting the upper vibration absorbing part;
An upper intermediate flat plate which is formed in a rectangular flat plate shape and is connected to the lower edge of each of the upper support frames so as to be rotatable at respective corners and spaced apart from the lower supporting flat plate;
A lower intermediate plate formed in the same plate shape as the upper intermediate plate and supported by the upper intermediate plate spaced apart from the upper side by a plurality of intermediate support frames formed on each surface;
Four intermediate vibration absorbing parts installed between the upper intermediate plate and the lower intermediate plate and supporting the upper intermediate plate using an elastic force;
Four lower support frames extending downward from the corners of the lower intermediate plate and supporting the lower intermediate frame;
Four lower vibration absorbers connected to the lower portions of the four lower support frames so as to be rotatable and absorbing vibrations transmitted from the lower support frame; And
And a lower support flat plate which is formed in the form of a rectangular flat plate and on which each of the lower vibration absorbing portions is provided,
Wherein the upper intermediate plate or the lower intermediate plate comprises:
And the upper and lower portions of the intermediate supporting frame are connected to the sliding grooves formed in the upper and lower directions and are slidable along the sliding grooves in a direction approaching or away from each other.
