Description

[Detailed Description of the Invention] The present invention relates to a raised structure for an underground underground facility equipped with a manhole iron cover, a special manhole iron cover, a fire hydrant iron cover, a water control valve iron cover, and various other types of cover bodies.

The purpose of this invention is to interpose a raising spacer between the lower trench of an underground object and the frame that receives its lid, thereby making it possible to fine-tune the height and perform construction work that adapts to the slope of the road. The object of the present invention is to provide a structure for raising the height of underground objects.

That is, in the present invention, one or more spacers 4, 4, etc. are interposed between a frame body 2 for receiving a cover body 1 of an underground buried object, and a lower chamber 3 to which the frame body 2 is attached,
Each spacer 4, 4... is provided with an engagement protrusion 7 that engages with the engagement groove 5 provided in the lower box 3 and the engagement recess 6 of the lower spacer 4, and an insertion hole 9 for the fixing bolt 8, and the frame Through holes 11 and 12 through which the bolts 8 are inserted are provided at predetermined positions in the flanges 2' and 3' of the body 2 and the lower shell 3, and nuts are screwed into the through holes 12 of the lower shell 3 to be screwed into the bolts 8. This is a raised structure for an underground object characterized by the fact that 10 is buried therein.

The present invention will be explained below with reference to illustrated embodiments.
Reference numeral 1 designates a lid for an underground underground object, and the example is a so-called triangular three-point support type lid, which is intended for use as an iron lid for a fire hydrant, and is a square iron lid divided into two diagonally. 2 is a receiving frame that directly receives the lid body 1, and 13 is a raising frame that is stacked on top of the receiving frame 2. The receiving frame 2 and the raising frame 1
All three are included in the framework of the present invention. Reference numeral 3 indicates a lower box to which the receiving frame 2 is attached, and reference numeral 4 indicates a spacer interposed between them. The spacer 4 has downward engaging protrusions 7 that engage with the engaging grooves 5 and 5 provided at two corners of the lower chamber 3, and the upper surface of the engaging protrusions 7 engages with the upper spacer 4. Engagement recess 6 that engages with engagement projection 7
It's getting old. Reference numeral 8 denotes a fixing bolt, 9 a through hole for the bolt, and through holes 11 and 12 for the bolt 8 are also provided in each of the flanges 2' and 3' of the receiving frame 2 and the lower box 3. Reference numeral 10 designates an insert nut, which has a cylindrical shape with flanges at both ends and is embedded integrally on the lower opening 12' side of the bolt through hole 12 of the lower shell 3 (see FIG. 4). Further, in the figure, 14 is a plurality of fixing pieces protruding from the inner edge of the receiving frame 2, 15 is a small hole provided in each fixing piece 14, 16 is a plurality of fixing pieces protruding from the inner edge of the raising frame 13, 17 indicates a small hole provided in each fixing piece 16, and both small holes 15 and 17 match when the receiving frame 2 and the raising frame 13 are overlapped. 18 is both small holes 1
5 and 17 to connect both frames 2 and 13, 19 is its nut, 20 and 21 are both frames 2 and 1
3 shows the engaging legs provided respectively. In the above configuration, the lower chamber 3 of the underground object does not need to be square, and the lid 1 does not need to be an iron lid.

To adjust the position and height of the lid body 1 using the above-mentioned raised structure, for example, as shown in Figure 2, when adjusting the position and height of the lid body 1 to suit the slope of the road surface where underground objects are buried, the right corner of the figure should be adjusted. The inserts are integrally embedded in the lower basin 3 with fixing bolts 8 at the four corners after inserting the required number of spacers 4, 4, etc. in each section.
It is sufficient to tighten the nut 12, and until the lower box 3 and the spacer 4 are tightened, they are fitted into each other through the engagement groove 5 or the engagement recess 6 and the engagement protrusion 7, so that displacement is prevented. Adjust the number of spacers 4 by performing the above operations.
For example, it is possible to respond to various road surfaces and ground changes by making complex adjustments such as one sheet at one corner, three sheets at the diagonal corner, and two sheets at each corner in between.
Furthermore, when it is necessary to raise the height after installation on a road, etc., by stacking the raising frame 13 on the receiving frame 2 in use and connecting it to the receiving frame 2 with bolts 18, it is possible to raise the height without digging up the receiving frame 2 (see Fig. 3). ), this can be combined with the above-mentioned spacers 4, 4, . . . for more flexible construction.

Therefore, according to the present invention, by interposing the necessary number of spacers 4, 4, .
height can be adapted, with spacers 4
is in the form of a small piece and has a structure for engaging with the lower pipe 3, etc., and a bolt tightening structure, so that the desired construction can be carried out accurately and quickly. 12 is provided through each of the flanges 2' and 3' of the frame 2 and the lower basin 3, so even if dirt or pebbles enter there, they will fall below the lower opening 12', so there is no risk of clogging. 3 through hole 12
Since the insert nut 10 is buried in the bolt, it is possible not only to prepare for bolt tightening work but also to be able to tighten the bolt reliably even if a bolt is too long.
