The utility model relates to a steel double-leaf flood-proof door which comprises a door frame, door leaves, an upper bolt clamping mechanism and a lower bolt clamping mechanism, the upper bolt clamping mechanism and the lower bolt clamping mechanism are arranged on the door leaves, a lower doorsill of the door frame is buried in a terrace, and the upper surface of the door frame is flush with the terrace; the upper part of the lower doorsill is provided with a plurality of openings for inserting bolts; the upper and lower bolt clamping mechanism comprises a bolt, a movable sinking water retaining block which moves up and down synchronously with the bolt is fixedly arranged on the bolt, the movable sinking water retaining block is in an L shape, the bottom face of the movable sinking water retaining block can cover the upper surface of the lower doorsill, and a rubber sealing piece is arranged on the side face of the movable sinking water retaining block to be attached to the door leaf. The lower doorsill is pre-buried in the terrace and kept on the terrace, when the plug pin is downwards inserted into the lower doorsill, the L-shaped movable sinking water retaining block moves downwards together, the bottom face of the L-shaped movable sinking water retaining block presses the lower doorsill, meanwhile, the side face of the L-shaped movable sinking water retaining block blocks a door crack in the bottom of the door leaf, and the good sealing and flood preventing functions are achieved.

A sill arrangement for a fenestration frame includes a sill with a first chamber, a second chamber, a third chamber, and a fourth chamber. The sill includes a first internal wall that separates the first chamber from the second chamber. The sill arrangement also includes a corner key with a first port defining a first passage between the first and second chambers and a second passage between the second and third chambers of the sill. Moreover, a second port is included on the sill-facing surface that defines a third passage between the third and fourth chambers for allowing fluid to flow from the third chamber to the fourth chamber. The corner key further includes a drain in communication with the fourth chamber.

The utility model discloses a door frame and a doorsill structure thereof, comprising: a base, which is provided with a first clamping groove, a second clamping groove and a clamping end from back to front in sequence, and the openings of the first clamping groove and the second clamping groove are arranged upwards; the plate body is arranged in the second clamping groove of the base; the threshold body is arranged in the first clamping groove of the base, and the front end of the threshold body abuts against the rear end of the plate body; and the clamping strip is clamped at the clamping end of the base, a first extending edge is arranged at the rear end of the clamping strip, and the first extending edge is pressed at the front end of the plate body. According to the scheme, the two ends of the plate body are limited through the clamping strip and the doorsill body correspondingly, so that the plate body is arranged in the base in a limited mode, a user can replace and adjust the plate body according to the needs of the user, the plate body replacement difficulty is small, and the attractiveness of the doorsill structure is high.

The invention relates to a sill arrangement having a pivotable sealing strip for a sliding door with a leaf which is displaceable along a running rail and, in the horizontal direction perpendicular to the running rail, can be positioned against a frame or moved away from the frame. When the leaf is open, the sealing strip is lowered, so that it terminates flush with a sill. When the leaf is pushed closed along the running rail, the sealing strip is at least partially raised. When the pushed-closed leaf is positioned against the frame, the sealing strip can be raised further. With the leaf bearing against the frame, the raised sealing strip provides sealing against a vertical front side of the leaf oriented parallel to the running rail. In particular, the leaf is continuously peripherally sealed off against the frame in the plane of the front side of the leaf, this sealing being provided by the sealing strip and further sealing structures fixed to the frame.

A threshold ramp adapted to be positioned adjacent to a threshold of a doorway and includes connecting plates; pivot mechanisms connecting the connecting plates; a plurality of ramp sections transversally connected between the connecting plates, U-shaped channels connecting adjacent ramp sections; a locking clamp located at a distal end of each one of the U-shaped channels; a prong located on each one of the U-shaped channels, each one of the prongs engages with the corresponding locking clamp of the U-shaped channel; and cables connecting the connecting plates. Each one of the pluralities of ramp sections rotate independently from each other, in regard to the first and the third connecting plates; and the first and the second pivot mechanisms move the first and the third connecting plates from an undeployed position to a deployed position, extending the ramp sections across the threshold when in the deployed position.
