Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
The utility model, by improving common comb-type telescoping device, provides a kind of novel comb-type telescoping device with excellent waterproof and multi-directional deflection function at this; Both remained the various function such as power transmission and vertical, horizontal displacement of common comb-type telescoping device, and allowed again stretching device be provided with waterproof and vertical deflection function.
The utility model comprises the fixed tooth plate and swing tooth plate that can be fixed on both sides beam-ends, its beam-ends gap portion is provided with adhesive waterproof tape along its length, in the middle part of described adhesive waterproof tape, its length is provided with lower concave part and supported on both sides portion, described adhesive waterproof tape can be " V " font, described adhesive waterproof tape both sides are respectively by two gripper shoe fixed supports, described gripper shoe can be supporting steel plate, described two gripper shoes are separately fixed on the beam-ends of both sides, and described adhesive waterproof tape two ends are sealed in the beam-ends of both sides admittedly respectively by concrete casting.Existing common to common comb-type telescoping device; between the hole of the anchor bolt that rainwater can be stitched by common comb usually and water proof rubber plate, gap flows into or infiltrates the bottom of rubber tile; because rubber tile covers again after pouring concrete; so always there is gap bottom rubber tile and between concrete; therefore the rainwater flowing into the bottom of rubber tile slowly will flow to beam-ends along these gaps, thus effective waterproof cannot be realized.And the V-type water proof rubber band of this novel comb-type telescoping device first installs fluid concrete again, so be very close to each other between concrete and water proof rubber band, between them, achieve real seamless link, therefore water resistance is very reliable.
The part that described V-type adhesive waterproof tape is connected with supporting steel plate, in " n " font, well can be fitted with supporting steel plate.Meanwhile, described V-type adhesive waterproof tape end has the flange arranged downwards, and described flange contacts with supporting steel plate and arranges, and the part of described contact is not less than 2.5cm.It is cast in concrete, thus effectively can stop rainwater and ooze out from the bottom of rubber strip.
This novel comb-type telescoping device has also set up the vertical deflection component-polyurethane high molecule flexible member of four cydariforms in every meter, the bottom of movable comb tooth plate, and is fixed on the bottom of movable comb tooth plate by four connecting bolts.This elastic polyurethane element has more excellent dynamic performance, fatigue behaviour and weather resistance than rubber; when the vertical corner reciprocal of bridge beam end generation any direction; small compressive strain is produced in any direction by four polyurethane high molecule flexible members; the additional forces of this displacement to stretching device can be dissolved, thus effectively protect stretching device.
A kind of comb-tooth bridge expansion device with excellent waterproof and multi-directional deflection that the utility model proposes, abandon the theory that traditional yielding rubber plate and water proof rubber band unite two into one, be provided with separately a V-type water proof rubber band, and fixed by supporting steel plate, simultaneously two ends are sealed on the beam-ends of both sides admittedly respectively by concrete casting, thus effectively can stop rainwater and ooze out from the bottom of rubber strip.Simultaneously, the polyurethane high molecule flexible member of four cydariforms has been set up in every meter, the bottom of movable comb tooth plate, the bottom of movable comb tooth plate is fixed on by four connecting bolts, this elastic polyurethane element has excellent dynamic performance and fatigue behaviour, effectively can adapt to the vertical corner reciprocal of all directions of beam-ends.The utility model provides a kind of reliable in function, simple for structure, easy for installation and have the comb-tooth bridge expansion device of excellent waterproof and multi-directional deflection function.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
