び取扱いが複雑になるという問題がある。(Prior art) In order to prevent noise and damage to concrete receivers caused by the grating jumping up when a car or the like runs on top of the grating laid as a gutter cover, etc., in the past, for example,
As shown in Japanese Patent Application No. 54-28954, a connector for sandwiching the main members of a grating has been proposed. That is, a pair of left and right clamping pieces of a connecting tool made by bending a plate material into a hollow trapezoid shape clamps the corresponding main members, and a guide piece is connected to the lower end of the clamping piece. The main members of the grating are connected to each other by attaching the connecting tool while the grating is locked to the lower surface of the main member. However, the above conventional connectors are
Since the guide piece is configured to abut against the lower surface of the main member and maintain its attached state, the length of the clamping piece is specified according to the height of the main member,
It is necessary to prepare connectors of various sizes to correspond to gratings of various sizes, resulting in a problem of poor productivity. In addition, if the clamping force of the connector decreases, there is a risk that the guide piece may come off the bottom surface of the main member, and to prevent this, it is necessary to connect the lower ends of the clamping pieces with bolts, etc. There is a problem that handling becomes complicated.

6, and the lower end clamping parts 7, 7 of the clamping pieces 6, 6 are connected to the gratings 1, 1.
It is configured to sandwich the side surfaces of the corresponding main members 2a, 2a. That is, the height H 1 of the clamping piece 6 is formed smaller than the height H 2 of the main member 2a, and the distance between the clamping parts 7, 7 of the clamping pieces 6, 6 is the sum of the thicknesses of the main members 2a, 2a. As shown in FIG. 2, the lower end clamping parts 7, 7 of the clamping pieces 6, 6 are set smaller than the
It is configured to be attached to the gratings 1, 1 in a state in which it is pressed against the middle part of the side surface of a.

By positioning the connecting tool 5 above the auxiliary member 3 in a state where they are in contact with each other, and pressing the guide groove 8 of the clamping piece 6 over the predetermined auxiliary member 3 from above as shown in FIG. The lower end clamping parts 7, 7 of the clamping pieces 6, 6 are fitted onto the corresponding main members 2a, 2a of the gratings 1, 1 to clamp them. Thereafter, by horizontally sliding the connector 5 along the main members 2a, 2a, the auxiliary member 3 is press-fitted into the locking groove 9, as shown in FIG.

る。 In this way, since the connector 5 is attached to the gratings 1, 1 with the auxiliary member 3 press-fitted into the locking groove 9, the attachment position of the connector 5 will shift even when the gratings vibrate. can be prevented. Therefore, it is possible to prevent the connector 5 from shifting upward and protruding from the upper surface of the grating 1, or from the connector 5 falling off from the grating 1 due to the gripping of the main members 2a, 2a being released by the clamping pieces 6, 6. This can be reliably prevented. Further, the lower end clamping parts 7, 7 of the clamping pieces 6, 6 are connected to the main members 2a, 2.
Since the main member 2a is configured to clamp the middle part of the side surface thereof, even if the height H2 of the main member 2a changes slightly, the clamping state by the clamping pieces 6, 6 may become unstable. Instead, the connectors 5 of the same size can be applied to gratings 1 of various sizes, and the connectors 5 can be mass-produced.

The guide portions 10, 10 are not an essential requirement and may be omitted. Further, as a means for locking the auxiliary member 3 by engaging the auxiliary member 3 and the locking groove 9, a check protrusion may be provided at the entrance of the locking groove 9 or the like.

The connector 5a may be constructed by providing a bent piece 11 which is formed by bending the center portion of the upper wall between the two ends of the connecting member 6 and projecting downward. According to this connector 5a, the bent piece 11 serves as a spacer interposed between the gratings 1,1.
