Description

Technical Field

[0001] The utility model relates to the technical field of box beam casting and forming, in particular to a box beam casting and forming device. Background Art

[0002] Box girder is a type of beam in bridge engineering. It is hollow inside and has flanges on both sides of the upper part, similar to a box, hence the name. Box girders of reinforced concrete structures are divided into prefabricated box girders and cast-in-place box girders. Prefabricated box girders are box girders prefabricated in an independent site and erected with a bridge erection machine after the foundation engineering is completed. For large continuous bridges, cast-in-place box girders are usually used. Cast-in-place box girders are cast in sequence on the box girder formwork with concrete at the construction site to form the bottom plate, web plate and top plate.

[0003] Since bubbles will be generated during the pouring process of the box girder, the bubbles will cause the quality of the box girder to be unqualified, and the cast box girder will be unusable and can only be re-cast, which will lead to reduced work efficiency. In addition, the box girder needs to be cast in multiple sections, so the forming device needs to be installed multiple times, which is time-consuming and labor-intensive, thereby reducing work efficiency. Therefore, a box girder casting and forming device is urgently needed to improve the above problems. Utility Model Content

[0039] The implementation principle of this embodiment is:

[0040] The box beam casting and forming device is provided with a base 1. When the box beam needs to be cast, the staff moves the base 1 to a suitable position, then the staff inserts the outer mold 3 into the interior of the slide groove 2, and puts the inner mold 5 in, then the staff installs the sleeve 26 into the interior of the mounting frame 25, and puts the top of the screw rod 27 to the bottom of the upper template 28, then the staff rotates the sleeve 26. Since the sleeve 26 is rotatably connected to the mounting frame 25, the sleeve 26 can rotate, and the rotation of the sleeve 26 can drive the screw rod 27 to move up and down, and then the screw rod 27 can lift the upper template 28, so that the installation of the inner mold 5 is more convenient. After the upper template 28 is moved to the desired position, the staff takes out the support block 33 and puts the support block 33 Insert it into the inside of the guide groove 31, at this time the slider 32 moves inside the guide groove 31, so that the support block 33 can move, with the movement of the support block 33, the spring lock will pop out into the inside of the limit groove 34, at this time the support block 33 can move with the inner mold 5, then the staff takes out the baffle 10, inserts the fixing rod 38 into the inside of the fixing plate 35, then the staff presses the positioning pin 37 in, at this time the positioning pin 37 cooperates with the positioning hole 39 to connect the baffle 10 with the inner mold 5, because the size of the baffle 10 is compatible with the outer mold 3, so the inner mold 5 can pass when the baffle 10 moves with the outer mold 3, then the staff injects concrete into the inside of the outer mold 3 through the feed port 9, and then the staff starts the motor 16.

[0041] At this time, the output shaft of the motor 16 starts to rotate, and the rotation of the output shaft of the motor 16 can drive the connecting rod 17 to rotate, and the rotation of the connecting rod 17 can drive the coupling 18 to rotate, and the rotation of the coupling 18 can drive the rotating rod 19 to rotate, and the rotation of the rotating rod 19 can drive the stirring blade 20 to rotate, so as to stir and vibrate the concrete, and thus eliminate the bubbles inside it. When the connecting rod 17 rotates, the gear 21 on its outer surface can rotate with the connecting rod 17, and at this time the gear 21 is meshed with the rack 23, so that the gear 21 can move on the outer surface of the rack 23, and then the mounting seat 14 will be forced to move. Since the bottom of the mounting seat 14 is provided with a sliding block 15, the sliding block 15 is sliding on the sliding block 15. The internal sliding of the movable groove 24 can move the mounting seat 14, so that the vibrating mechanism 8 can evenly stir and vibrate the concrete, thereby eliminating the bubbles inside it. When the pouring is completed and the second section needs to be poured, the staff takes out another base 1, installs the two bases 1 through the first mounting block and the second mounting block, and then moves the outer mold 3. At this time, the outer mold 3 can move inside the slide groove 2. Since the baffle 10 and the inner mold 5 are connected, the inner mold 5 can move with the outer mold 3, so that the second section of the box girder can be quickly poured, which can reduce the time required for construction and improve work efficiency. When disassembly is required, the above method and process can be reversed.

[0042] Compared with the prior art, the present invention has the following beneficial effects:

[0043] 1. The box beam casting and forming device is provided with a vibrating mechanism 8, which can drive the connecting rod 17 to rotate through the rotation of the motor 16, thereby driving the driving coupling 18 to rotate, thereby driving the rotating rod 19 to rotate, thereby stirring and vibrating the concrete, and when the connecting rod 17 rotates, the gear 21 on its outer surface is meshed with the rack 23, thereby driving the mounting seat 14 to move, thereby enabling the vibrating mechanism 8 to move evenly, thereby eliminating bubbles generated during the concrete casting process, thereby improving work efficiency;

[0044] 2. The box girder casting and forming device is provided with a slide groove 2, and the outer mold 3 can be moved through the slide groove 2. Since the baffle 10 is in contact with the outer mold 3, the movement of the outer mold 3 can drive the baffle 10 to move, and the movement of the baffle 10 can drive the internal part to move, so that the casting of the box girder can continue, reducing the time for reinstalling the forming device, thereby shortening the time for casting the box girder. A lifting mechanism 6 is provided, and the lifting mechanism 6 can make the installation and disassembly of the inner mold 5 more convenient, thereby reducing the construction time and improving the work efficiency.
