  The present invention solves the above-described problems, and at least one of the following effects can be obtained.

<1> Twist of seal member, twist and tear due to the twist can be prevented when male and female of the box are fitted.
<2> Since the vicinity of the seal member attachment position of the male end portion is reinforced, damage in the vicinity of the male end portion during male-female fitting of the box can be prevented.
<3> Even if an opening is provided in the joint portion of the box, the sealing property can be secured.
<4> It is possible to prevent a gap from being generated at the interface between the embedded portion (the root insertion portion) of the seal member and the box body, which is a measure against water stoppage.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<1> Overall Configuration A case where a concrete box culvert 1 is used in the box of the present invention will be described as an example.
FIG. 1 is a perspective view of a seal member mounting structure of a box culvert 1 according to the present invention, FIG. 2 is a partially enlarged view of the seal member mounting structure when the box culvert 1 is inserted, and FIG. It is a front view of the male end A side.
In addition, the box of the present invention is not limited to the box culvert, but can be fitted in a row with a seal member between the inner and outer surfaces of the female end and the male end in an assembly-type manhole or fire prevention water tank. As long as it is a member to be configured and has a defective portion on the joint surface between the female end and the male end, the mounting structure of the seal member of the present invention can be employed.

<2> Box culvert 1
The box culvert 1 shown in FIG. 1 is configured so that it can be fitted with a slot by interposing a seal member 2 between the inner and outer surfaces of the female end B and the male end A, and the joint surface D between the female end B and the male end A is deficient. It has a structure having a part C.
The defect portion C is formed to provide an opening for installing another structure such as a manhole in the box culvert 1 so as to straddle between the male end A and the female end B of the box culvert 1. It is formed by providing.
The shape of the defect portion C may be circular, rectangular, or any other shape, and is not limited to the case where a single portion is provided between the male end A and the female end B as shown in FIG. A plurality of locations may be provided on the joint surface D.

  As shown in FIG. 2, both the male outer peripheral surface 4 and the female outer peripheral surface 5 of the box culvert 1 may be formed in parallel with the axial direction of the box culvert 1. Any one surface may be formed in parallel with the axial direction of the box culvert 1.

<3> Seal member 2
The sealing member 2 uses a known member such as rubber. As the seal member 2 in FIG. 2, a rubber body having a kerf at the top and an intermediate hole inside is often used. The rubber body is embedded in a ring shape along the outer peripheral surface 4 of the male end, and is configured to seal water by press-fitting into the gap between the male end A and the female end B when the box culvert 1 is fitted. Is done.

  In this embodiment, for convenience of explanation, one connection end provided with a protruding portion on the inner side of the box culvert 1 is a male end A, and conversely, the other one provided with a protruding portion on the outer side of the box culvert 1. Is defined as a female end B, and the sealing member 2 and the reinforcing tool 3 are provided at the male end A. However, the sealing member 2 and the reinforcing tool 3 may be provided at the female end B instead of the male end A. Alternatively, the seal member 2 and the reinforcing tool 3 may be provided at both the male end A and the female end B.

<4> Reinforcing tool 3
The reinforcing tool 3 is disposed in the vicinity of the defect portion C and at a position interposed between the seal member 2 and the male end A.
The material of the reinforcing tool 3 is made of an elastic member such as metal or rubber, or a plastic material such as plastic or resin.
The shape of the reinforcing tool 3 includes a staple type (FIG. 4A) and a type arranged around the embedded portion of the seal member (FIG. 4B), but is limited to the shape of the embodiment. Instead, a well-known shape that can resist the twisting of the seal member when the box is fitted with a male and female can be employed. For example, the reinforcing tool 3 may include a form in which the staple type is intermittently arranged.

  Here, the attachment method of the reinforcing tool 3 will be described in more detail.

The first attachment method is a method in which the reinforcing member 3 is attached to the male end A of the box culvert 1 in a state where it is integrated with the seal member 2 in advance.
In this method, the reinforcing tool 3 is attached to a predetermined position of the seal member 2 in advance before molding the box culvert, and the male end A of the box culvert 1 is attached by vibration compaction by attaching the seal member 2 to the mold. The seal member 2 and the reinforcing member 3 can be integrally molded to form a box provided with the seal member mounting structure according to the present invention.

In the second attachment method, the box culvert 1 is molded in a state in which a space for attaching the reinforcement tool 3 is secured in advance, and the reinforcement tool 3 is attached to the space before the male and female of the box culvert 1 are fitted together. It is a method of interposing between A.
FIG. 5 is a partial perspective view of the seal member mounting structure according to the second mounting method.
As shown in FIG. 5, the male end A of the box culvert 1 is molded in a state in which an insertion groove 6 that is a mounting space for the reinforcing tool 3 is provided in the vicinity of the defect C in advance when molding with a mold. By inserting the reinforcing member 3 into the insertion groove 6 before the male and female of the culvert 1 are fitted, a box culvert having a seal member mounting structure according to the present invention is formed.
In addition, you may join the reinforcement tool 3, the sealing member 2, and the male end A more firmly by well-known joining methods, such as an adhesive agent.

[Functions and actions of the present invention]
Next, functions and operations of the seal member mounting structure of the present invention will be described.
When the box culvert 1 is fitted into the male and female, the reinforcing member 3 resists the force received from the female end B by the seal member 2 in the vicinity of the defect, so that the seal member 2 is prevented from being twisted and twisted or torn due to the twist. In addition, no gap is generated at the interface between the embedded portion of the seal member 2 and the male end A of the box culvert 1.
Therefore, the male and female of the box culvert 1 can be fitted without damaging the sealing member 2, and the water sealing property of the sealing member 2 after fitting can be ensured.

Further, even when the box culvert 1 is removed, the reinforcing member 3 resists the force that the seal member 2 tends to twist toward the opposite direction when fitted, so that the seal member 3 is not twisted or torn. .
Therefore, according to the mounting structure of the seal member of the present invention, it is possible to suppress the deterioration of the performance of the seal member due to repeated fitting and removal of the box culvert.
