Description
Technical Field
[0001] This utility model belongs to the field of bridge engineering construction technology, and specifically relates to a cast-in-place protective plate for bridge engineering construction. Background Technology
[0002] Bridge engineering is widely used for crossing obstacles such as highways, railways, canals, or pipelines. With the development of transportation, bridge engineering not only involves building bridges over natural obstacles such as rivers and canyons, but also constructing overpasses in cities and building extra-long span bridges in coastal areas. The main body of a bridge is formed by pouring concrete. Before the main body is constructed, when some auxiliary structures need to be built, cast-in-place protective plates are used for support and protection, thus facilitating the pouring construction.
[0003] Problems with existing technology:
[0004] The existing cast-in-place retaining plates are often fastened with bolts at the joints after splicing. This splicing and fixing method is not only cumbersome to operate, but also troublesome to disassemble later, thus reducing construction efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a cast-in-place protective plate for bridge construction, which can solve the above-mentioned technical problems.
[0006] The specific technical solution adopted by this utility model is as follows:
[0007] This utility model provides a castable protective plate for bridge construction, comprising two protective plate bodies and a base plate. The back of the two protective plate bodies is provided with a supporting mechanism, and the lower back of the two protective plate bodies is respectively provided with a snap-fit plate. The base plate is formed with two sets of snap-fit grooves, and the snap-fit plate is inserted into the snap-fit grooves. The base plate is provided with a side support mechanism, and the back of the protective plate body is provided with a tensioning mechanism for tightening the side support mechanism.
[0008] The supporting mechanism includes a first fixed plate and a second fixed plate fixed on opposite sides of the back of two slide body parts. The first fixed plate is provided with a first extension plate on its upper and lower sides respectively. A supporting plate is provided between the two first extension plates on the side away from the first fixed plate. The second fixed plate is provided with a second extension plate on its upper and lower sides respectively. The two second extension plates are respectively fitted with two slots formed on the supporting plate. A support shaft is rotatably provided on the side of the two second extension plates away from the second fixed plate. An expansion supporting mechanism is provided on the support shaft.
[0009] When splicing two main body panels of a bridge construction project using the aforementioned cast-in-place protective plate, the insertion plate is inserted into the corresponding insertion slot, simultaneously causing the two second extension plates on the support mechanism to engage with the slots on the support plates. Then, the inserting plate is rotated to align with the slot, and the adjusting screw is rotated using a tool. This causes the adjusting screw to move the pushing plate closer to the moving plate, simultaneously moving the two counter-pushing plates. The counter-pushing plates, relying on the support shaft, push the moving plate and the fixed-axis support plate to move, while simultaneously causing the inserting plate to embed into the slot. As the adjusting screw continues to rotate, the counter-pushing plates push the support shaft and support plates away from each other, thus bringing the two main body panels closer together and reducing the gap width after splicing. Later, during disassembly, the inserting plate can be released from its engagement with the slot by rotating the adjusting screw in the opposite direction, facilitating the separation of the two main body panels.
[0010] Preferably, the expansion mechanism includes rotating plates disposed on the upper and lower sides of the support shaft, with sliding frames slidably mounted on the two rotating plates respectively, and a movable plate disposed between the two sliding frames. An adjusting screw is rotatably mounted on the movable plate, and a push plate is threadedly mounted on the adjusting screw. A counter-push plate is movably mounted on opposite sides of the push plate.
[0011] Preferably, each of the two rotating plates is fitted with a telescopic rod, and a locking plate is provided at the free end between the two telescopic rods. The side of the supporting plate is formed with a groove for the locking plate to be inserted. A fixed shaft is provided between the two telescopic rods, and the opposite ends of the two push plates are rotatably engaged with the support shaft and the fixed shaft, respectively.
[0012] Preferably, the side support mechanism includes a blocking plate and a side support plate disposed on the base plate, a baffle is disposed on the upper side of the back of the main body of the guard plate, the baffle is in blocking contact with the upper side of the side support plate disposed on the back of the main body of the guard plate, and an expansion plate is disposed on the lower side of the side support plate, the expansion plate being provided with a locking shaft adapted to the blocking plate.
[0013] Preferably, the tensioning mechanism includes a rotating sleeve, which has two opposing spiral threads that are threaded into two movable screws. The lower side of the movable screw is movably connected to the back of the guard plate body via a hinge seat.
[0014] Preferably, the upper movable screw is fitted with a sleeve hole formed on the side support plate, and a clamping plate adapted to the sleeve hole is provided on the upper side of the upper movable screw.
[0015] Preferably, one side of the protective plate body is formed with a plug groove, and the other side of the protective plate body is provided with a plug plate that is plugged into the plug groove.
[0016] The beneficial effects are:
[0017] 1. This utility model uses an adjusting screw on the support mechanism to push and adjust the two push plates, causing the push plates to push the locking plate on the telescopic shaft away from the support plate and the support shaft, thereby driving the two guard plate bodies closer together. This improves the tightness of the splicing of the two guard plate bodies. Secondly, it is also convenient for disassembly in the future. By rotating the adjusting screw, the pushing and tightening of the two guard plate bodies can be released, thus facilitating the splicing, fixing and disassembly of the two guard plate bodies.
[0018] 2. This utility model uses the side support plate on the side support mechanism to make the bottom plate pull the side support plate closer by the tensioning mechanism, thereby adjusting the tightening force on the back of the guard plate body, improving the verticality adjustment of the support on the back of the guard plate body, and thus improving the support effect on the back of the guard plate body.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.
[0027] like Figure 1-5 As shown, a castable protective plate for bridge construction includes two main protective plates 1 and a base plate 8. The back of the two main protective plates 1 is provided with a supporting mechanism 4. The lower back of the two main protective plates 1 is provided with a snap-fit plate 10. The base plate 8 is formed with two sets of slots 9. The snap-fit plate 10 and the slots 9 are inserted and matched. In this way, the positioning and support effect of the base plate 8 on the lower side of the main protective plate 1 can be improved by the insertion of the snap-fit plate 10 and the slots 9. The base plate 8 is provided with a side support mechanism. The back of the main protective plate 1 is provided with a tensioning mechanism 5 for tightening the side support mechanism.
[0028] The supporting mechanism 4 includes a first fixed plate 401 and a second fixed plate 407 fixed on opposite sides of the back of two slide body panels. The first fixed plate 401 is provided with a first extension plate 402 on its upper and lower sides respectively. A supporting plate 403 is provided between the two first extension plates 402 on the side away from the first fixed plate 401. The second fixed plate 407 is provided with a second extension plate 406 on its upper and lower sides respectively. The two second extension plates 406 are respectively engaged with two slots 9 formed on the supporting plate 403. A support shaft 405 is rotatably provided on the side of the two second extension plates 406 away from the second fixed plate 407. An expansion mechanism is provided on the support shaft 405.
[0029] As an optional implementation, the expansion mechanism includes rotating plates 416 disposed on the upper and lower sides of the support shaft 405. Sliding frames 415 are slidably mounted on the two rotating plates 416 respectively. A movable plate 413 is disposed between the two sliding frames 415. An adjusting screw 412 is rotatably mounted on the movable plate 413. A push plate 411 is threadedly mounted on the adjusting screw 412. A counter-push plate 410 is movably mounted on opposite sides of the push plate 411. The free end of the adjusting screw 412 is provided with an internal hexagonal groove, which facilitates rotational adjustment using a hexagonal wrench or other tools, thereby improving the ease of adjustment.
[0030] See attached document Figure 2 and attached Figure 3Two rotating plates 416 are respectively fitted with telescopic rods, and a locking plate 408 is provided at the free end between the two telescopic rods. The side of the support plate 403 is formed with a groove 404 for the locking plate 408 to be fitted. A fixed shaft 409 is provided between the two telescopic rods. The opposite ends of the two push plates 410 are respectively rotatably engaged with the support shaft 405 and the fixed shaft 409. With this arrangement, when the push plate 410 pushes the locking plate 408, the movement trajectory of the locking plate 408 is restricted by the sleeve of the telescopic shaft 414 and the rotating plate 416, thereby improving the pushing effect of the locking plate 408.
[0031] See attached document Figure 5 The side support mechanism includes a blocking plate 7 and a side support plate 6 set on the base plate 8. A baffle 11 is set on the upper side of the back of the guard plate body 1. The baffle 11 makes blocking contact with the upper side of the side support plate 6 set on the back of the guard plate body 1. An expansion plate 602 is set on the lower side of the side support plate 6. A locking shaft 603 adapted to the blocking plate 7 is provided on the expansion plate 602. This arrangement allows the side support plate 6 and the blocking plate 7 to be easily embedded. The locking shaft 603 forms a movable support for the side support plate 6, thereby facilitating the side support movement adjustment of the side support plate 6.
[0032] See attached document Figure 4 The tensioning mechanism 5 includes a rotating sleeve 501. The rotating sleeve 501 has two opposing spiral threads that are threaded into two movable screws 502. The lower side of the movable screw 502 is movably connected to the back of the guard plate body 1 through a hinge seat. The outer circumference of the spiral sleeve is provided with two symmetrical ear plates, which facilitates the rotation and adjustment of the spiral sleeve, thereby driving the movable screw 502 to pull down the pressure plate 503 and improve the side support effect of the side support plate 6 on the back of the guard plate body 1.
[0033] Furthermore, the upper movable screw 502 is fitted with the sleeve hole 601 formed on the side support plate 6. A clamping plate 503 adapted to the sleeve hole 601 is provided on the upper side of the upper movable screw 502. In this way, the clamping plate 503 can be used to form a downward pulling force on the side support plate 6, thereby improving the side support fixing effect of the side support plate 6.
[0034] Furthermore, one side of the protective plate body 1 is formed with an insertion groove 2, and the other side of the protective plate body 1 is provided with an insertion plate 3 that is inserted and matched with the insertion groove 2. When two protective plate bodies 1 are spliced, the insertion plate 3 and the insertion groove 2 are inserted and matched to provide stress support at the splicing point, thereby improving the splicing and fixing effect.
[0035] Using the above structure, when splicing the two main body plates 1, the insertion plate 3 is inserted into the corresponding insertion slot 2, and at the same time, the two second extension plates 406 on the support mechanism 4 are engaged with the slots 9 on the support plate 403. Then, the insert plate 408 is rotated to align with the slot 404, and the adjusting screw 412 is rotated by a tool, causing the adjusting screw 412 to move the push plate 411 closer to the moving plate 413, and at the same time, it moves the two counter-push plates 410, so that the counter-push plates 410 push the moving plate 413 and the fixed shaft by means of the support shaft 405. 409 moves towards the support plate 403, simultaneously driving the insert plate 408 to embed into the groove 404. Then, as the adjusting screw 412 continues to rotate, it drives the push plate 410 to push the support shaft 405 and the support plate 403 away from each other. This can drive the two guard plate bodies 1 to move closer to each other, thereby reducing the gap width after the two guard plate bodies 1 are spliced. In this way, when disassembling later, by adjusting the adjusting screw 412 in the opposite direction, the insert plate 408 and the groove 404 can be released from their jamming state, thus making it easier to separate the two guard plate bodies 1.
[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
