おいてボルト８の強度を向上している。A synthetic resin bolt 8 is inserted into each insertion hole 5 of the connecting plate 2 from the relief portion 5b side, and the threaded portion 9 of the bolt 8 is inserted into the inserter 1.
It is designed to be screwed into the screw hole 7 of ~6. The threaded portion 9 of the bolt 8 has a diameter slightly smaller than the width of the restriction portion 5a of the insertion hole 5 of the connecting plate 2, so that it can be inserted into the insertion hole 5, and the restriction portion 5a of the insertion hole 5 allows the screw portion 9 of the connection plate 20 to be inserted into the insertion hole 5. Movement in the width direction is restricted. A washer 11 having a diameter equal to the width of the connecting plate 2 and the width of the connecting plate 2 is integrally formed between the threaded portion 9 and the head 10 of the bolt 8, and is capable of abutting and engaging with the support portion 4. . Between the screw part 9 and the washer 11, there is a relief part 5 of the insertion hole 5 of the connecting plate 2.

個の側溝りが連結具１により離間不能に連結される。In order to connect side gutters with the connector 1 configured as described above, first, inserts 6 are buried in predetermined positions of the side walls S when manufacturing the side gutters. Then, the connecting plate 2 is placed on the side wall S so that the insertion hole 5 communicates with the screw hole 7 of the insert 6, and the screw portion 9 of the bolt 8 is screwed into the screw hole 7 of the insert 6 through the insertion hole 5. , the washer 11 comes into contact with the support portion 4 and presses the connecting plate 2 toward the insert 6 via the support portion 4 . As a result, the connecting plate 2 is firmly held between the bolt 8 and the insert 6, and the connecting plate 2 is made immovable relative to the gutter, and the adjacent two
The two side gutters are connected inseparably by the connecting tool 1.

。Of the connector 1 having the above configuration, the connecting plate 2, a part of the bolt 8,
A part of the tip surface 6a of the inserter 1-6 is exposed to the outside when connecting the side gutter, but since they are all made of synthetic resin, they will not be corroded by rainwater, drainage, etc. Therefore, there is no need for special work to prevent corrosion as in the past, and the number of steps for the connection work can be reduced, and workability in the connection work is improved.

機能が容易には損われることがない。In addition, since the bolts 8 are made of synthetic resin, there are concerns about their strength compared to conventional metal bolts, especially between the heads 10 of the poles I to 8 and the threaded portions 9 when connecting in a gutter. Since a considerable stress is applied to the bolt 8, there is a concern that the bolt 8 may be damaged in the same portion. However, by forming a clearance part 5b in the insertion hole 5 of the connecting plate 2, the width of which is larger than the diameter of the threaded part 9 of the bolt 8, the head 10 of the bolt 8 and the threaded part 9 are formed in correspondence with the clearance part 5b. A reinforcing portion 12 can be formed in between. As a result, the strength between the head 10 and the threaded part 9 is improved by the reinforcing part 12, and the bolt 8 is not easily damaged between the head 10 and the threaded part 9 during gutter connection. , the connecting function of the connector 1 is not easily impaired.
さらに、連結板２は、支持部４のみ肉厚として連結部３
は肉薄としたため、全体の材料の量を少くすることがで
き、材料費を低減することができる。Further, in the connecting plate 2, only the supporting portion 4 is thick and the connecting portion 3 is thick.
Since it is thin, the total amount of material can be reduced, and material costs can be reduced.
