Summary of the invention:
The utility model is intended to solve the problem of freely stretching of aqueduct beam body in the hydraulic engineering, and a kind of aqueduct stretching device is provided.This device is suitable for large-scale hydraulic engineering to be used, and reliability, the application life that can improve the aqueduct stretching device greatly, satisfies the multiple instructions for use of aqueduct beam body.
The purpose of this utility model realizes by implementing following technical proposals:
A kind of aqueduct stretching device is characterized in that: be provided with the adhesive waterproof tape that the middle part has hole between two aqueduct beam-ends, this edge of a wing, adhesive waterproof tape both sides is provided with detachable fastener.
Described fastener comprises pressing plate and end steel plate, and the edge of a wing, both sides of adhesive waterproof tape is held between pressing plate and the end steel plate, and pressing plate and end steel plate have with the suitable die cavity of the edge of a wing, adhesive waterproof tape both sides shape.
The steel plate welding of the described end is anchored at the aqueduct beam-ends, and pressing plate is connected with end steel plate through connecting bolt.
The inside of described pressing plate is provided with the middle steel plate that increases pressing plate rigidity.
The hole at described adhesive waterproof tape middle part is no less than one, and its cross sectional shape is an approximate parallelogram.
Have 1～3 row hole in the described adhesive waterproof tape, separate by vertical dowel with the hole of delegation.
The upper and lower surface of the telescopic section of described adhesive waterproof tape has makes adhesive waterproof tape produce the fold of different-stiffness at different directions.
The edge of a wing, described adhesive waterproof tape both sides has and prevents that thereby the cross section that comes off from adding macrostructure or increasing the structure that contact surface increases frictional force.
Described adhesive waterproof tape has identical or akin cross sectional shape in the elongated direction of stretching device.
Advantage of the present utility model is: can adapt to the three-dimensional motion of aqueduct beam body 1.; 2. can make the aqueduct stretching device of big displacement quantity; 3. adhesive waterproof tape adopts the sealing of face contact resilient through particular design, the tight waterproof of energy, and can bear enough hydraulic pressure; 4. adhesive waterproof tape has from dirt eliminating function; 5. design takes into full account the anticorrosion and reliability of aqueduct stretching device under abominable environment for use, has strengthened application life; 6. the utility model compact conformation is easy for installation, and making and maintenance cost are low; 7. especially be fit to the multiple mode of occupation such as aqueduct that the beam-ends cross section is an abnormity.
Description of drawings:
Fig. 1 is the utility model cross-sectional configuration schematic diagram.
The specific embodiment:
A kind of aqueduct stretching device comprises adhesive waterproof tape 1, end steel plate 2 (containing anchor system), pressing plate 3 and connecting bolt 4.
Following characteristics are arranged in described adhesive waterproof tape 1: (1), material are weather-proof, anticorrosion, anti-aging type elastic rubbery body; (2), the middle part has and is no less than a hole 5, the cross sectional shape of hole is approximate parallelogram; (3), separately by vertical dowel between the adjacent holes 5 with delegation, has triplex row hole (only containing delegation's hole among the figure) at the most; (4), the upper and lower surface of adhesive waterproof tape telescopic section has and can make adhesive waterproof tape produce the fold of different-stiffness at different directions; (5) thereby, the edge of a wing, adhesive waterproof tape both sides 6 has and prevents that the cross section that comes off from adding macrostructure or increasing the structure (be expressed as spherical cross section among the figure and add macrostructure) that contact surface increases frictional force; (6), adhesive waterproof tape has same or analogous cross sectional shape in elongated direction.
The end described in the utility model steel plate 2 has and the edge of a wing, adhesive waterproof tape both sides 6 corresponding cavity structures, and end steel plate 2 is anchored at the aqueduct beam-ends by welding.When the aqueduct beam-ends does not have built-in fitting, can adopt implantation reinforcing bar or bolt behind the aqueduct beam-ends, to weld with end steel plate again.
Pressing plate 3 described in the utility model has and the edge of a wing, adhesive waterproof tape both sides 6 corresponding cavity structures, adopts elastomeric material, and 7 inner of middle steel plates play increase pressing plate rigidity, can have, and also can not have.
The end described in the utility model steel plate 2 and pressing plate 3 link together by bolt, and after pressing plate took down, adhesive waterproof tape 1 can easy removal.
Thereby the edge of a wing, both sides 6 of adhesive waterproof tape 1 described in the utility model is the bracketed part by pressing plate 3 to be pressed on and to prevent on the end steel plate 2 that adhesive waterproof tape 1 from coming off and prevent seepage between pressing plate 3, end steel plate 2, adhesive waterproof tape 1 three.
After the utility model was installed to the aqueduct beam-ends, the mode that adopts fluid concrete or fill in waterproofing materials was filled up the remaining space of preformed groove.
