JPS603188Y2 - Gage block for manhole - Google Patents

Description

[Detailed description of the invention] This invention relates to a gauge block used when attaching side pipes such as hume pipes, vinyl chloride pipes, ceramic pipes, etc. to a manhole structure, and more specifically, the present invention relates to a gauge block that supports the lower surface of the side pipes of a manhole. The present invention relates to a manhole gauge block characterized in that a concave bottom surface and a horizontal surface that can define the bottom position of a side pipe are arranged and provided on the upper surface, respectively.

Recently, prefabricated manholes have been adopted in various places due to their quick construction and workability.
As shown in the figure, the side pipe 2 attached to the manhole body 1
, 3, how to accurately set the height of the pipe bottom has become a major problem.

The gauge block according to the present invention relates to a completely new technology developed in view of the conventional problems.

To specifically explain one embodiment of the present invention with reference to the drawings, the second embodiment is as follows.
In the figure, 4 is a gauge block of the present application, the bottom surface 5 of which is formed horizontally, and the corresponding top surface 6.
■ The outer peripheral surface of the side pipe 2.3 can be supported in the left and right center parts.
A concave bottom surface a having the shape of a shape is provided, and furthermore, on both left and right sides of this concave bottom surface a, a middle horizontal surface C and an upper horizontal surface C, which maintain a predetermined height through sloped surfaces, are provided symmetrically in parallel. Further, a bolt hole 7 is formed in the lower part of the block 4 in the front-rear direction.

In the above embodiment, the height of the middle horizontal plane C is such that when the side tube 2 is placed on the concave bottom surface a of this block 4 as shown in FIG. It is configured in advance so that the height is the same as that of the height.

In addition, the difference in height between the middle horizontal surface C and the upper horizontal surface C in the above embodiment is due to the bottom plate 1 provided on the bottom surface of the manhole frame 1.
The height difference is equal to the height difference between the outer bottom surface 9 and the inner bottom surface 12 of No. 3.

Therefore, when the block 4 is inserted inside the manhole body 1, this block 4 is installed on the inner bottom surface 12 of the bottom plate 13, and when the side pipe 2 is supported via a spacer, the upper horizontal surface of the side pipe 2 It is designed to match the tube bottom e of the tube.

However, this upper horizontal surface is not a requirement, so this part can be omitted.

When using the block 4 according to the present invention, as shown in FIG. 3 and FIG. 5 is placed on the outer bottom surface 9 of the bottom plate 13 of the manhole to stabilize it, and the bolt hole 7 of this block 4 is
The block 4 is fixed to the frame 1 by inserting the bolt 10 into the block 1 and screwing it into the embedded plug 11 that has been embedded in the frame 1 in advance. Next, the side pipe 2 is placed on the concave bottom surface a of the block 4. In particular, as shown in FIG. 4, the bottom e of the side tube 2 and the middle horizontal surface C of the upper surface 6 of the block 4 are automatically aligned to position and stabilize the side tube 2, and in this state, By filling the gap between the hole 8 of the frame 1 and the side pipe 2 with mortar, the side pipe 2 can be integrally attached and fixed to the frame 1 in a stable state.

Also, when installing the side pipe 3, by fixing the block 4 to a predetermined position on the outer surface of the manhole that has been measured in advance, it can be easily installed using the same work process.

According to the present invention, the gauge block is provided with intermediate horizontal planes on both sides of the V-shaped concave bottom surface capable of supporting the side pipes as described above, which are equal to the bottoms of the side pipes supported by the blocks.
By using the block of the present invention, the bottom position of the side pipe can be determined accurately and automatically, and therefore the side pipe can be correctly supported within the hole of the manhole frame, and the hole and side Since the side pipe can be supported semi-permanently by the block until the mortar filled between the pipe and the pipe is completely fixed, the side pipe can be accurately fixed without shifting its position, and is extremely easy to work with. The invented block can be easily constructed from concrete or the like, so it can be mass-produced at low cost.
