The utility model discloses a river course construction cofferdam structure, it includes a plurality of longitudinal baffle, the surface fixedly connected with the clasp strip of baffle, between two baffle is provided with the connecting angle board, the connecting angle board is adapted with baffle, and eight symmetries fixed frame are provided between a plurality of baffle, the surface of clasp strip is provided with two pairs of symmetrical clamp, the surface fixedly connected with two symmetrical connecting plates of clamp. The utility model discloses through placing two clamps on the surface of clasp strip, makes fixed bolt and thread connection nut through two connecting plates, so that fixed frame passes between two limit plates, makes fixed bolt and thread connection nut through limit plate, gasket, fixed frame, can reach the fixed beam of cofferdam structure can be fixed through the clamping structure to cofferdam structure, avoids the cofferdam structure and needs to be repaired after using, guarantees the leakproofness of cofferdam structure.

The utility model relates to the technical field of building construction, and concretely discloses a protective window rail suitable for construction temporary protection, which comprises a permanent protective window rail, the permanent protective window rail comprises a permanent protective window horizontal pole and a permanent protective window vertical pole, and a temporary protection frame is detachably installed on the permanent protective window rail, the temporary protection frame comprises a horizontal telescopic rod arranged between the permanent protective window horizontal pole and a floor slab, the temporary protection frame can fill the gap between the permanent protective window vertical pole and the floor slab, thereby achieving the purpose of temporary protection, and the temporary protection frame is arranged on the inner side of the protective window rail to play a construction protection function, which can avoid the direct collision of construction appliances or construction personnel on the permanent protective window rail, thereby forming protection for the permanent protective window rail, after the completion of construction, the horizontal telescopic rod is retracted, and then the temporary protection frame is dismounted and installed on the next construction part, so that the protective window rail can be repeatedly used.

This application provides a display back panel and a display device. The display back panel includes a substrate and a plurality of light-emitting components. The light-emitting components include a first light-emitting unit and a second light-emitting unit. When one light-emitting component is in a working state, the first light-emitting unit and the second light-emitting unit emit light in a time-sharing manner when both are working normally. When either the first light-emitting unit or the second light-emitting unit malfunctions, the normally working light-emitting unit continues to emit light. The display back panel provided by this application can avoid repairing malfunctioning light-emitting units when one light-emitting component is in a working state, reducing the number of rework operations and further improving the display quality of the display back panel. It can also delay the light decay time of the display back panel and extend its service life.
