Description

  This device assembles and embeds buried boxes such as handholes and manholes in a multi-stage assembly structure that is buried in the ground surface so that the wiring and piping of various cables buried in the ground are aggregated and branched. In doing so, the present invention relates to a guide suspension fitting for an assembly-type embedded box such as a handhole or a manhole in which an upper slab is reliably positioned in its normal position with respect to a lower base or the like so that it can be easily assembled.

  Conventionally, burial boxes such as handholes and manholes of this type are installed and installed in the burial site, for example, by placing concrete materials on site, and by prefabricated frame materials, panel materials, etc. Is provided by. For example, the assembly-type hand hole disclosed in Patent Document 1 has been standardized for each predetermined size having an inclined joining piece bent outward so as to be a box-shaped hand hole made of reinforced plastic including a bottom plate, a side plate, and a top plate. Side plate assembling plates are prepared, and side walls adjusted to the embedding depth can be formed and assembled by increasing or decreasing the number of stacked sheets. The hand hole of Patent Document 2 is assumed to be assembled by attaching a bottom panel, a side panel, and a top panel to a frame material that is assembled in a cubic shape to form a skeleton.

  However, according to the assembly-type hand hole in Patent Document 1, it is necessary to perform a fastening operation between the side plate assembling plates in the field. Also, according to the hand hole in Patent Document 2, the screws of each panel to the frame material in the field are similarly used. Stop and rivet stop are required, and in any case, it takes time and effort.

  In order to solve these problems, a handhole base constructed in a box shape with a predetermined size on the factory side and a handhole slab constructed in a cylindrical shape are prepared, and the base is first installed in the installation hole excavated on site. There has been proposed a multi-stage assembly-type handhole that is assembled by hanging and placing a slab on the suspension, positioning and stacking. For example, it can be assembled by stacking in multiple stages along the vertical direction at the installation site as seen in the sleeve tube connection structure in Patent Document 3 and the suspension structure of concrete products in Patent Document 4. It is a hand hole. The hand hole in Patent Document 3 is provided with uneven portions on the mating surfaces stacked in the upper and lower stages so that the alignment can be performed, and the hand hole in Patent Document 4 is the inner surface angle of the hand hole base when stacked in the vertical direction. A hanging metal fitting is embedded and fixed in a chamfered portion formed in the portion, and the handhole base can be suspended and transported by this hanging metal fitting.

  In such a multistage assembling type handhole, a predetermined handhole can be constructed by stacking work at the site, but in any of the assembling type handholes shown in Patent Document 3 or Patent Document 4, the lower level base or the like is used. It is assembled by hanging down the upper slab. In order to accurately align in the vertical direction at the time of lowering, it is necessary to visually check the worker and positioning adjustment work for the alignment. There is a risk that groundwater or the like may enter the interior from the joint and damage the internal storage equipment. In addition, there is a case where a water-stopping tape or the like is interposed between the upper and lower mating surfaces as a water-stop treatment for preventing the ingress of groundwater or the like into the seam. In order to wear it, the waterproofing tape is assumed to be sticky. However, this sticky waterproof tape can be removed between the base and slab due to its stickiness when it is placed with a misalignment when stacking the upper slabs stacked on the base. This makes it difficult to correct the misalignment.
