Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] like figure 1 As shown in the figure, the problem to be solved by the present invention is to provide an all-round self-adaptive comb-shaped telescopic device to realize horizontal, torsional, vertical and other all-round self-adaptive displacement, including a stainless steel plate 9, a cross-slot plate 7 and a water stop Belt 8, on the steel fiber concrete A13, is provided with a cross-slit plate 7, each module of the cross-slit plate 7 is 120mm-160mm, and its end is connected to the rotating ball head 4 through a bolt 3. The fixed plate 10 is arranged on the steel fiber concrete B14, the rubber block 1 is arranged under one end of the cross-slot plate 7, and the rotating ball head 4 is arranged under the cross-slot plate 7, so that each cross-slot plate 7 corresponds to a rotating ball head 4. , the outside of the rotating ball head 4 is a ball head cover 5;...

Abstract

The invention discloses an omnibearing self-adapting pectinate expansion device which comprises seam crossing plates and a waterstop strip. The invention is characterized in that steel fiber concrete A is provided with the seam crossing plates; a fixed plate is arranged on steel fiber concrete B; a rubber block is arranged below one end of the seam crossing plates; a rotating bulb is arranged below each seam crossing plate; thus, each seam crossing plate corresponds to one rotating bulb and connected with the rotating bulb to form an integral body; a bulb sleeve is arranged outside each rotating bulb; a tetrafluoroethylene plate is filled between each rotating bulb and each bulb sleeve; silicone grease which has the function of lubrication is filled in the gaps; one side of the seam crossing plates of the device is provided with a spacer pin groove and a spacer pin; and the waterstop strip is arranged between the steel fiber concrete on the two sides. In the invention, the rotating mechanism, seam crossing plates and bridge beam slabs form two independent units, so that the two independent units can make a relative movement, thereby realizing position change in a horizontal, torsion, vertical or any other mode.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a comb-shaped telescopic device with omnidirectional self-adaptive function. Background technique [0002] The existing comb-shaped telescopic device can only meet the expansion and contraction along the bridge direction caused by the thermal expansion and cold contraction of the bridge girder plate, because the rotating shaft is in the transverse bridge direction, and the rotating mechanism, the span plate and the bridge girder plate are integrated. Complex displacements such as horizontal, torsional and vertical cannot be achieved. [0003] The Chinese invention patent with the application number of 200810201913.4 introduces a multi-directional displacement bridge telescopic device, which includes a movable tooth plate, a fixed tooth plate, and a rubber waterstop. The specific content is that the movable tooth plate and the fixed tooth plate are placed flat on stainless steel...
