[0002] Prefabricated box girders refer to box-shaped girders produced in factories or prefabrication plants. The interior of this type of beam is hollow, with flanges on both sides of the upper part, similar to a box, hence the name. Prefabricated box girders are usually prefabricated in an independent site, and then transported to the construction site and directly assembled into a large cross-span structure. Compared with traditional cast-in-place box girders, prefabricated box girders have the advantages of short production cycle, controllable quality, and fast construction speed. By sealing the ends, concrete leakage can be prevented, ensuring that the concrete inside the box girder is fully dense.

[0003] In the prior art, when fixing the end formwork of the box girder formwork, it is inconvenient to support the end formwork at the beginning of fixing, and the hoisting equipment needs to be used to hoist the end formwork all the time, which takes up a lot of time for the hoisting equipment. In addition, when squeezing and fixing the end formwork, it is generally necessary to rotate the threaded sleeve many times before the end formwork can be squeezed and fixed. However, rotating the threaded sleeve many times is time-consuming, which makes fixing more troublesome. Utility Model Content

Example

[0028] Reference Figures 1 to 5 , which is the first embodiment of the utility model, provides a box girder formwork end mold support device, the box girder formwork end mold support device includes a main body component 100, including a box girder 101 and an end mold 102, and the end mold 102 is located at the end of the box girder 101.

[0029] The end formwork 102 is used to seal the end of the box beam 101 to prevent concrete leakage and ensure that the concrete inside the box beam is fully dense.

[0030] The support assembly 200 is arranged at the end of the box beam 101, and includes an insertion rod 201a inserted into the box beam 101, a fixing sleeve 201b is fixed on the surface of the insertion rod 201a, a positioning tube 201c is fixed on the surface of the fixing sleeve 201b, a connecting rod 201d is inserted in the positioning tube 201c, a threaded rod 201e is fixed to the end of the connecting rod 201d, a threaded sleeve 201f is rotatably connected to the surface of the threaded rod 201e, an extrusion disk 201g is provided on one side of the threaded sleeve 201f, and the other end of the threaded rod 201e is fixedly connected to the positioning rod 201h, and the positioning rod 201h slides in another connecting rod 201d.

[0031] There are two groups of insertion rods 201a, two in each group, all of which are inserted into the box beam 101 and are used to support the fixed sleeve 201b. By connecting the two positioning tubes 201c, the angle of the insertion rod 201a can be limited so that the insertion rod 201a will not rotate. By rotating the threaded sleeve 201f, the threaded sleeve 201f can be used to squeeze the extrusion plate 201g, so that the extrusion plate 201g squeezes the connecting rod 201d, thereby making the two connecting rods 201d move away from each other, so that the two connecting rods 201d push the two positioning tubes 201c, thereby driving the two insertion rods 201a to move away from each other, so that the two insertion rods 201a squeeze the inner wall of the hole in the box beam 101, so that the two insertion rods 201a are fixed in the box beam 101.

[0032] Specifically, the support assembly 200 further includes a support member 202 disposed on the surface of the fixing sleeve 201b, including a support sleeve 202a fixed to the surface of the fixing sleeve 201b.

[0033] When the two positioning tubes 201c are connected, the two supporting sleeves 202a are in a horizontal state.

[0034] Specifically, a support shaft 202b is rotatably connected to the support sleeve 202a through a thread, a support block 202c is provided on one side of the end mold 102, and a positioning block 202d is fixed to the bottom of the support block 202c.

[0035] By rotating the support shaft 202b, the support shaft 202b can be fixed in the support sleeve 202a, and the support shaft 202b is in a horizontal state. The support block 202c is located on the top of the support shaft 202b, so that the support shaft 202b can support the end mold 102 through the support block 202c, so that the end mold 102 does not require lifting equipment for a long time. The positioning block 202d is used to prevent the support block 202c from slipping off the support shaft 202b.

[0036] Specifically, a chamfer is provided at the bottom of the positioning block 202d, and the positioning block 202d is fitted on the surface of the support shaft 202b.

[0037] The bottom of the positioning block 202d is chamfered to prevent the support shaft 202b from being scratched. The positioning block 202d is attached to the surface of the support shaft 202b to prevent the support block 202c from slipping off the support shaft 202b.

[0038] Specifically, there are four supporting blocks 202 c symmetrically arranged on both sides of the end mold 102 .

[0039] The symmetrically arranged support blocks 202c can provide stable support for the end mold 102.

[0040] Specifically, two positioning blocks 202d are provided at the bottom of each supporting block 202c.

[0041] By embracing the support shaft 202b with two positioning blocks 202d, the stability of the support block 202c on the top of the support shaft 202b can be improved. Example

[0042] Reference Figures 1 to 5 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0043] Specifically, the support assembly 200 also includes a fixing part 203, which is arranged on the surface of the support shaft 202b, including a movable sleeve 203a sliding on the surface of the support shaft 202b, a limiting strip 203b fixed in the movable sleeve 203a, and a sliding groove 202b-1 is opened on the surface of the support shaft 202b, and the limiting strip 203b slides in the sliding groove 202b-1.

[0044] By providing the limiting strip 203b and the sliding groove 202b-1, the movable sleeve 203a can slide stably on the surface of the support shaft 202b without causing the movable sleeve 203a and the support shaft 202b to rotate relative to each other.

[0045] Specifically, a positioning shaft 203c is fixed in the movable sleeve 203a, and a pressing plate 203d is rotatably connected to the surface of the positioning shaft 203c.

[0046] The positioning shaft 203c is used to support the extrusion plate 203d so that the extrusion plate 203d can rotate freely.

[0047] Specifically, a clamping column 203e is fixed on the extrusion plate 203d, and a clamping groove 202b-2 is opened on the surface of the support shaft 202b, and the clamping column 203e is inserted into the clamping groove 202b-2.

[0048] By rotating the extrusion plate 203d, the clamping column 203e can be clamped in the clamping groove 202b-2, thereby positioning the movable sleeve 203a so that the movable sleeve 203a cannot move on the support shaft 202b.

[0049] Specifically, the surface of the movable sleeve 203a is rotatably connected to the extrusion sleeve 203f through a thread, and the surface of the extrusion sleeve 203f is fixedly connected to the handle 203g.

[0050] By moving the handle 203g, the extrusion sleeve 203f can be driven to rotate, so that the extrusion sleeve 203f moves on the surface of the movable sleeve 203a, so that the extrusion sleeve 203f squeezes the support block 202c on one side of the movable sleeve 203a, so that the support block 202c squeezes the end mold 102 on the end of the box beam 101, preventing concrete leakage and ensuring that the concrete inside the box beam is fully dense.

[0051] During use, when it is necessary to fix and support the end mold 102, first insert two rods 201a on one side of the box beam 101. During this process, keep the two connecting rods 201d in the two positioning tubes 201c. When the rod 201a is inserted into place, rotate the threaded sleeve 201f so that the threaded sleeve 201f can squeeze the extrusion plate 201g, so that the extrusion plate 201g squeezes the end of one of the connecting rods 201d, thereby making the two connecting rods 201d move away from each other, so that the two connecting rods 201d push the two positioning tubes 201c, thereby driving the two rods 201a to have a tendency to move away from each other, so that the two rods 201a squeeze the inner wall of the hole in the box beam 101, so that the two rods 201a are fixed in the box beam 101, thereby providing stable support force for the end mold 102, and then fix the two rods 201a to the other side of the box beam 101 in the same way.

[0052] Then fix the four support shafts 202b in the four support sleeves 202a, and hoist the end mold 102 through the hoisting equipment, so that the four support blocks 202c on both sides of the end mold 102 fall on the four support shafts 202b, and make the positioning blocks 202d fit the surface of the support shafts 202b, so as to ensure that the end of the end mold 102 and the box beam 101 are aligned. At this time, move the extrusion plate 203d to make the clamping column 203e move out of the clamping groove 202b-2, so that the movable sleeve 203a moves to the side of the support block 202c, and the extrusion plate 203d can be rotated at this time so that the clamping column 203e is clamped in the clamping groove 202b-2, The movable sleeve 203a is positioned so that the movable sleeve 203a cannot move on the support shaft 202b. At this time, the extrusion sleeve 203f is rotated by the handle 203g, so that the extrusion sleeve 203f squeezes the support block 202c on one side of the movable sleeve 203a, so that the support block 202c squeezes the end mold 102 on the end of the box beam 101 to prevent concrete leakage and ensure that the concrete inside the box beam is fully dense. During the movement of the extrusion sleeve 203f, the extrusion plate 203d can be located in the extrusion sleeve 203f, thereby preventing the extrusion plate 203d from driving the card column 203e to move out of the card slot 202b-2.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
