Description

Technical Field

[0001] The invention relates to the technical field of prefabricated box beams, and in particular to a prefabricated box beam mould which is easy to assemble and disassemble and has stable connection. 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. It is divided into single box and multiple boxes. As one of the important structures in bridge engineering, reinforced concrete box girder is divided into prefabricated box girder and cast-in-place box girder according to the concrete pouring method. Among them, cast-in-place box girder refers to the box girder directly cast at the construction site. Prefabricated box girder is prefabricated in advance in an independent site, and then hoisted after the lower structure of the bridge is completed. Because prefabricated box girder can effectively avoid cross-construction interference, greatly improve the progress of the project and save construction time, it is widely used.

[0003] In the prior art, the inner mold core of the prefabricated box girder is mostly a split structure, and the various parts are hinged. There are splicing gaps at the hinge positions, which causes poor appearance quality after the box girder is cast. When assembling the mold, it is connected into a fixed structure by bolts. Not only is the number of bolts large and the workload is heavy, but also because the space of some core bodies is very narrow, the cross-sectional dimensions at the opening are small, and the cross-sectional dimensions of the internal dimensions are large, people cannot enter at all, and the mold core can only be pulled out as a whole by a high-power winch. During the pulling process, it is easy to rub against the inner wall of the box girder, causing surface damage. For this reason, the present application proposes a prefabricated box girder mold that is easy to disassemble and assemble and has stable connection, and provides a new technical solution to solve the technical problems mentioned above. Summary of the invention

[0045] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0046] Embodiment 1:

[0047] Please refer to Figure 1 - Figure 6 , a prefabricated box beam mold which is easy to disassemble and assemble and has stable connection, comprising:

[0048] A bottom mold 1 is provided with side molds 2 on both sides of the bottom mold 1, the bottom mold 1 and the side molds 2 form an outer membrane, and an inner mold 3 is provided on the inner side of the outer membrane; further, a pressure plate 12 is provided at both ends of the bottom mold 1, and a support platform 11 is provided at the lower end of the side mold 2. When the side mold 2 is connected to the bottom mold 1, the pressure plate 12 is located above the support platform 11, and the support platform 11 is tightly fitted with the pressure plate 12, so that the end of the bottom mold 1 is lifted by the lower end of the side mold 2.

[0049] A support platform 4 is arranged at the bottom of the side mold 2 and is used to lift and support the bottom mold 1;

[0050] A supporting mechanism 1 5, which is arranged outside the side mold 2 and is used for extrusion support of the side mold 2;

[0051] A second supporting mechanism 6, which is arranged on the inner side of the inner mold 3 and is used for lifting and supporting the inner mold 3;

[0052] Specifically, the side mold 2 includes an upper middle mold piece 13, a lower middle mold piece 14, an upper end mold piece 15, and a lower end mold piece 16. The upper middle mold piece 13 and the lower middle mold piece 14 are symmetrically arranged up and down. The upper end mold piece 15 is located at the two ends of the upper middle mold piece 13. Both ends of the upper middle mold piece 13 are mutually attached to the upper end mold piece 15 at the same end. The lower end mold piece 16 is located at the two ends of the lower middle mold piece 14. Both ends of the lower middle mold piece 14 are mutually attached to the lower end mold piece 16 at the same end. The ends of the upper end mold piece 15 and the lower end mold piece 16 at the same end are mutually attached.

[0053] Furthermore, a support platform 27 is provided at both ends of the upper middle mold piece 13, a pressure plate 28 is provided at both ends of the lower middle mold piece 14, a pressure plate 3 29 and a pressure plate 4 30 are provided at both ends of the upper mold piece 15, and a pressure plate 5 31 and a support platform 32 are provided at both ends of the lower mold piece 16; the pressure plate 3 29 at the end of the upper mold piece 15 is located above the support platform 27 at the end of the upper middle mold piece 13, and the pressure plate 3 29 is tightly fitted with the support platform 27; the support platform 32 at the end of the lower mold piece 16 is located below the pressure plate 28 at the end of the lower middle mold piece 14, and the support platform 32 is tightly fitted with the pressure plate 28; the pressure plate 4 30 at the end of the upper mold piece 15 is located outside the pressure plate 5 31 at the end of the lower mold piece 16, and the pressure plate 4 30 is tightly fitted with the pressure plate 5 31.

[0054] It can be seen that the supporting mechanism 2 6 is divided into six parts as a whole, namely, upper left, upper middle, upper right, lower left, lower middle, and lower right. The cooperation of the "support and pressure plate" at the ends of the upper middle mold piece 13, the lower middle mold piece 14, the upper end mold piece 15, and the lower end mold piece 16 can effectively ensure the stability of the end connection. During demolding, the upper middle mold piece 13, the lower middle mold piece 14, the upper end mold piece 15, and the lower end mold piece 16 can be gathered toward the center direction of the side mold 2, thereby separating the side mold 2 from the inner wall of the box beam, so that when the side mold 2 is taken out, it will not be scratched against the inner wall of the box beam, thereby ensuring the integrity of the inner wall of the box beam.

[0055] Specifically, the supporting mechanism 2 6 includes a fixed beam 17, and the upper and lower ends of the fixed beam 17 are respectively provided with a lifting mechanism 18 and a lifting mechanism 2 19, the telescopic end of the lifting mechanism 18 is detachably connected to the lower middle mold piece 14, and the telescopic end of the lifting mechanism 2 19 is detachably connected to the upper middle mold piece 13, and the two end angle positions of the same end of the fixed beam 17 are respectively provided with a lifting mechanism 3 20 and a lifting mechanism 4 21, the telescopic end of the lifting mechanism 3 20 is detachably connected to the upper end mold piece 15, and the telescopic end of the lifting mechanism 4 21 is detachably connected to the lower end mold piece 16, and the inner side of the fixed beam 17 is fixedly connected with an installation inner plate 22, and the ends of the lifting mechanisms 3 20 and 21 close to the fixed beam 17 extend to the inner side of the fixed beam 17, and the ends of the lifting mechanisms 3 20 and 21 located on the inner side of the fixed beam 17 are detachably fixedly connected to the lifting mechanism 3 20.

[0056] It can be known that the upper middle mold piece 13 and the lower middle mold piece 14 can be driven to move through the cooperation of the jacking mechanism 1 18 and the jacking mechanism 2 19, and the upper end mold piece 15 and the lower end mold piece 16 can be driven to move through the cooperation of the jacking mechanism 3 20 and the jacking mechanism 4 21. Before the box girder is cast, the upper end mold piece 15, the lower end mold piece 16, the upper middle mold piece 13 and the lower middle mold piece 14 are unfolded in turn. Conversely, when demolding, the upper middle mold piece 13 and the lower middle mold piece 14, the lower end mold piece 16, and the upper end mold piece 15 are gathered toward the center direction of the side mold 2 in turn, thereby avoiding collision when the upper middle mold piece 13, the lower middle mold piece 14, the upper end mold piece 15, and the lower end mold piece 16 move.

[0057] Furthermore, guide movable rods 23 are arranged in parallel inside the side mold 2 and at positions on both sides of the lifting mechanism 18 and the lifting mechanism 2 19. The guide movable rods 23 are vertically slidably connected to the fixed beam 17. The guide movable rods 23 on both sides of the lifting mechanism 2 19 and one end away from the fixed beam 17 are detachably connected to the upper middle mold piece 13, and the guide movable rods 23 on both sides of the lifting mechanism 18 and one end away from the fixed beam 17 are detachably connected to the lower middle mold piece 14.

[0058] Furthermore, a guiding movable rod 25 and a guiding movable rod 3 26 are respectively provided at the two end corner positions of the same end of the fixed beam frame 17, and the guiding movable rod 25 and the guiding movable rod 3 26 are both slidably connected to the fixed beam frame 17. The guiding movable rod 25 is located at a position on one side of the lifting mechanism 4 21, and the guiding movable rod 25 is arranged in parallel with the lifting mechanism 4 21. The end of the guiding movable rod 25 away from the fixed beam frame 17 is detachably fixedly connected to the lower end mold piece 16, and the guiding movable rod 3 26 is arranged in parallel with the lifting mechanism 3 20, and the end of the guiding movable rod 3 26 away from the fixed beam frame 17 is detachably fixedly connected to the upper end mold piece 15. It can be seen that through the guidance of the guiding movable rod 1 23, the guiding movable rod 25 and the guiding movable rod 3 26, the movement of the upper middle mold piece 13, the lower middle mold piece 14, the upper end mold piece 15 and the lower end mold piece 16 can be made more stable.

Specifically, Figure 2As shown, the support mechanism 1 5 includes a column 7, and a support base frame 8 and a support middle frame 9 are fixedly connected to the side of the column 7 close to the side mold 2. The support base frame 8 is located at the lower part of the column 7, and the support middle frame 9 is located at the middle part of the column 7. The ends of the support base frame 8 and the support middle frame 9 away from the column 7 are detachably connected to the side mold 2. A reinforcement frame 10 is also provided between the column 7 and the side mold 2. The reinforcement frame 10 is provided at the upper and lower ends of the support middle frame 9, and the reinforcement frame 10 is provided obliquely. Through the above structural design, the movement of the side mold 2 can be driven by the column 7, and the connection and support between the column 7 and the side mold 2 are realized by the support base frame 8, the support middle frame 9, and the reinforcement frame 10.

[0061] Embodiment 3:

[0062] The prefabricated box beam mold provided in Example 1, which is easy to disassemble and assemble and has stable connection, is further optimized. Specifically, Figure 7-Figure 8 As shown, guide grooves 24 are provided at the upper and lower ends of the fixed beam 17 and at positions corresponding to the guide movable rod 23. The guide movable rod 23 is slidably connected to the fixed beam 17 through the guide grooves 24. Pulley blocks are fixedly connected on both sides of the guide grooves 24. The guide movable rod 23 is rollingly connected to the guide grooves 24 through the pulley blocks.

[0063] Specifically, the pulley group includes a fixed plate 33, which is fixedly connected to the inside of the guide slide groove 24. The fixed plate 33 is rotatably connected to a vertical guide wheel 34 and a horizontal guide wheel 35 on one side close to the guide movable rod 23. The vertical guide wheel 34 and the horizontal guide wheel 35 are vertically arranged up and down. Both sides of the guide movable rod 23 are provided with horizontal slide rails 36, and the inside of the horizontal slide rails 36 is provided with vertical slide rails 37. The vertical guide wheel 34 is rollingly connected to the horizontal slide rail 36, and the horizontal guide wheel 35 is rollingly connected to the vertical slide rail 37.

[0064] Through the above-mentioned structural design, the static friction between the guiding movable rod 23 and the lower middle mold piece 14 can be changed into dynamic friction through the pulley group, thereby reducing the friction coefficient and making the movement resistance of the guiding movable rod 23 smaller; and through the cooperation of the vertical guide wheel 34 and the horizontal slide rail 36, and the cooperation of the horizontal guide wheel 35 and the vertical slide rail 37, the limiting effect of the movement of the guiding movable rod 23 can be achieved, and the occurrence of the deviation of the guiding movable rod 23 can be reduced, so that the movement of the upper middle mold piece 13 and the lower middle mold piece 14 can be more stable.
