Description

Technical Field

[0001] This utility model relates to the field of anti-collision wall technology, and in particular to a construction device for chamfering the top surface of a bridge anti-collision wall. Background Technology

[0002] Crash barriers, typically located on both sides of a bridge, are composed of reinforced concrete and are an essential component of the bridge structure. They not only provide crucial safety for vehicles and pedestrians but also enhance the bridge's aesthetics. The primary function of crash barriers is to prevent damage from collisions between vehicles and the bridge structure, minimizing the damage caused by accidents. In terms of construction, crash barriers are usually constructed using cast-in-place reinforced concrete, requiring steps such as formwork installation, rebar tying, and concrete pouring. Bridge crash barriers typically feature linear continuity, regular cross-sections, and relatively fixed height and thickness. Existing slipform casting machines allow for continuous casting and shaping of regular cross-section structures along a fixed trajectory.

[0003] In existing technologies, the chamfering of the top two sides of concrete during the slipform pouring process relies heavily on manual labor. This manual operation is inefficient and consumes a lot of manpower and time in the construction of large bridge crash barriers. Furthermore, the quality of manual chamfering is inconsistent due to the skill level and working conditions of the workers. Therefore, we propose a chamfering construction device for the top surface of bridge crash barriers to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a construction device for chamfering the top surface of a bridge crash barrier.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bridge crash barrier top surface chamfering construction device includes a slipform machine body. A casting template is fixedly connected to the outer wall of the slipform machine body. Two mounting plates are fixedly connected to the outer wall of the casting template. Two T-shaped slide rails are fixedly connected to the outer walls of the two mounting plates. Two slide bars are slidably sleeved on the outer walls of the two T-shaped slide rails. Two threaded holes are opened on the outer walls of the two slide bars. Fastening bolts are threadedly connected to the inner walls of the four threaded holes. Straight rods are fixedly connected to the outer walls of the two slide bars. Vertical sleeves are fixedly connected to one end of the two straight rods. Threaded rods are threadedly connected to the inner walls of the two vertical sleeves. Bearings are fixedly sleeved on the bottom outer walls of the two threaded rods. Chamfering plates are fixedly connected to the outer rings of the two bearings. Smoothing plates are fixedly connected to the bottom of the two chamfering plates. Guide components are provided on the outer walls of the straight rods.

[0007] Preferably, the guide assembly includes two vertical rods, the bottom of which is fixedly connected to the top of two chamfered plates respectively. The outer walls of the two vertical rods are provided with sliding holes, and the inner walls of the two sliding holes are slidably connected to the outer walls of the two vertical rods respectively. The guide assembly is used to assist the two chamfered plates in moving up and down.

[0008] Preferably, a rubber washer is rotatably fitted onto one end of the fastening bolt. The outer wall of the rubber washer is pressed against the outer wall of the T-shaped slide rail. The rubber washer increases the friction between the rubber washer and the T-shaped slide rail. After the fastening bolt is tightened, it provides sufficient compressive force to fix the position of the slide bar.

[0009] Preferably, a manual rotating disc is fixedly connected to the top of each of the two threaded rods. The manual rotating disc drives the threaded rod to rotate, causing it to move up and down through the vertical sleeve.

[0010] Preferably, the outer wall of the casting template is fixedly connected to a hopper, which is used to pour concrete into the casting template.

[0011] Preferably, the outer wall of the slide bar is slidably connected to the outer wall of the T-shaped slide rail.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution significantly improves the efficiency of chamfering construction by using two chamfering plates to compress the top two surfaces of the concrete as the slipform machine moves, combined with a trowel to smooth out excess concrete. This effectively ensures the construction quality of the chamfered top surface of the crash barrier.

[0014] It can flexibly adapt to the chamfering requirements of the top surface of the crash barrier with different heights and widths. The height of the chamfering plate can be adjusted by rotating the manual rotary dial, and the spacing of the chamfering plate can be adjusted by sliding and fixing it on the T-shaped slide rail. It is easy to operate and adjust, and has a wider range of applications. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1-3 As shown, a construction device for chamfering the top surface of a bridge crash barrier is disclosed, comprising a slipform machine body 1 (NC1300), a casting template 2 fixedly connected to the outer wall of the slipform machine body 1 (NC1300), and a material hopper 3 fixedly connected to the outer wall of the casting template 2. The slipform machine body 1 serves as a moving carrier, which can drive the casting template 2 and the material hopper 3 to move continuously along the longitudinal direction of the bridge, thereby realizing the continuous casting and forming of the crash barrier concrete and ensuring the integrity of the structure.

[0022] The outer wall of the casting template 2 is fixedly connected to two mounting plates 4. The outer walls of the two mounting plates 4 are fixedly connected to two T-shaped slide rails 5. The outer walls of the two T-shaped slide rails 5 are slidably fitted with two slide bars 6. The outer walls of the slide bars 6 are slidably connected to the outer walls of the T-shaped slide rails 5. The special cross-sectional design of the T-shaped slide rails 5 (wide at the head and narrow at the bottom) can limit the slide bars 6, prevent the slide bars 6 from leaving the track during the sliding process, and ensure the stability of the lateral adjustment.

[0023] Two threaded holes are opened on the outer wall of each of the two slide bars 6. The inner wall of each of the four threaded holes is threaded with a fastening bolt 7. A rubber washer 8 is rotatably fitted on one end of the fastening bolt 7. The outer wall of the rubber washer 8 is pressed against the outer wall of the T-shaped slide rail 5. The fastening bolt 7, together with the rubber washer 8, achieves rapid fixation of the slide bar 6 by pressing the outer wall of the T-shaped slide rail 5. The rubber washer 8 can increase the friction and improve the reliability of fixation.

[0024] Straight rods 9 are fixedly connected to the outer walls of both slide bars 6. Vertical sleeves 10 are fixedly connected to one end of each of the two straight rods 9. Threaded rods 11 are threadedly connected to the inner walls of both vertical sleeves 10. Manual rotating disks 12 are fixedly connected to the tops of both threaded rods 11. The straight rods 9 connect the slide bars 6 and the vertical sleeves 10 to form a stable lateral support structure. The threads on the inner walls of the vertical sleeves 10 cooperate with the threaded rods 11 to provide a vertical moving track for the threaded rods 11, ensuring that the chamfered plate 14 can be raised and lowered when the threaded rods 11 rotate.

[0025] Bearings 13 are fixedly fitted on the bottom outer walls of both threaded rods 11. Chamfer plates 14 are fixedly connected to the outer rings of both bearings 13. The bearings 13 are tapered roller bearings, so that the threaded rods 11 will not drive the chamfer plates 14 to rotate synchronously when they rotate, but only transmit the driving force in the vertical direction, ensuring that the chamfer plates 14 always press the concrete top surface in a stable posture.

[0026] The bottom of each of the two chamfering plates 14 is fixedly connected to a troweling plate 15. The arc-shaped surface of the inner wall of the chamfering plate 14 can squeeze the top two sides of the concrete to form a standard chamfer in one go, replacing manual operation. The troweling plate 15 is set at an angle to smooth the excess concrete squeezed out during the chamfering process downwards, avoid concrete accumulation, and ensure the flatness of the top surface.

[0027] The outer wall of the straight rod 9 is provided with a guide assembly, which includes two vertical rods 16. The bottom of the two vertical rods 16 is fixedly connected to the top of the two chamfered plates 14 respectively. The outer wall of the two straight rods 9 is provided with sliding holes, and the inner wall of the two sliding holes is slidably connected to the outer wall of the two vertical rods 16 respectively.

[0028] Working principle: During use, the pouring template 2 and hopper 3 on the slipform machine body 1 move with the slipform machine body 1. During the slow movement, concrete is poured onto the pre-placed reinforcing cage. Simultaneously, two chamfered plates 14 move with the machine. These two chamfered plates 14 are located on either side of the top surface of the poured concrete. During movement, the two chamfered plates 14 use their inner curved surfaces to press against the top surface of the concrete. Excess concrete is smoothed downwards by an inclined trowel 15, eliminating the need for manual chamfering. Furthermore, this method is suitable for the top surfaces of crash barriers of varying heights and widths. During chamfering, the two manual rotary discs 12 are rotated to drive the two threaded rods 11 to move up and down through the two vertical sleeves 10. The bottoms of the two threaded rods 11 drive the chamfering plate 14 to move up and down through the two bearings 13. The chamfering plate 14 moves up and down in a straight line through the vertical rod 16 and the sliding hole. The two straight rods 9 move horizontally on the two T-shaped slide rails 5 through the two slide bars 6. By rotating the four fastening bolts 7, the four rubber pads 8 are pressed against the outer wall of the two T-shaped slide rails 5 to fix the position of the two slide bars 6. The distance between the two chamfering plates 14 can be adjusted.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
