Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a curbstone concrete back casting and molding device. Background Art

[0002] In road construction, the pouring of the concrete back of the curb is an important task. The traditional method of pouring the concrete back of the curb has many shortcomings. When facing the pouring of the back of the curb at the corner of the road, it is usually necessary to pour the construction on both sides of the corner separately. This step-by-step pouring method has a complicated process. First, the formwork must be supported and poured on one side. After the concrete is initially solidified, the formwork must be removed, and the same formwork and pouring process must be repeated on the other side. This series of steps not only consumes a lot of manpower, material resources and time, greatly reducing the construction efficiency, but also because the two pouring processes are difficult to accurately connect, it is easy to have problems such as unevenness and gaps at the joints, which seriously affects the aesthetics and overall quality of the back. To this end, we proposed a device for pouring and forming the concrete back of the curb. Utility Model Content

[0023] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0024] Figure 1 to Figure 6 It is the best embodiment of the utility model, and the following Figure 1~Attached Figure 6 The utility model is further described.

[0025] A device for casting and forming a curbstone concrete backrest comprises a backrest machine body 1, wherein both ends of the backrest machine body 1 are connected with connecting pipes 2, and connecting columns 3 are movably connected inside the two connecting pipes 2, and the lower ends of the two connecting columns 3 are connected with baffles 4, and the front and / or rear ends of the baffles 4 are provided with shaping plates 5, and the shaping plates 5 are L-shaped, and connecting grooves 6 are provided on the front and rear end surfaces of the baffles 4, and a connecting block 7 is fixedly connected to a side wall surface of the shaping plate 5 close to the baffle 4 at a position corresponding to the connecting groove 6, and the connecting block 7 is movably clamped in the corresponding connecting groove 6, and two connecting holes 9 are provided on the upper wall surface of the baffle 4 at positions corresponding to the two connecting grooves 6, and a limited position fixing mechanism is provided inside the two connecting holes 9.

[0026] When in use, the backrest machine body 1 is set up on the curbstone where the backrest needs to be cast. When the backrest needs to be cast at the corner of the road, the connection block 7 on the shaping plate 5 is inserted into the corresponding side connection groove 6 on the baffle 4, and fixed by the limit fixing mechanism on the corresponding side connection hole 9. Since the shaping plate 5 is L-shaped, the backrest at the corner of the road can be cast at one time, which can not only greatly improve the work efficiency, but also because the cast backrest is integrally formed, it is more beautiful. Since the front and rear ends of the baffle 4 can be connected to the shaping plate 5, the shaping plate 5 can be installed at one end of the baffle 4 according to the actual use situation when in use, thereby improving the practicality of the device.

[0027] The limiting fixing mechanism includes a limiting block 10, a movable groove 13, a limiting ring 14 and a spring 15. The two connecting holes 9 are respectively slidably connected to the limiting blocks 10. The lower ends of the two limiting blocks 10 pass through the corresponding connecting holes 9 and extend to the connecting groove 6. The connecting hole 9 is provided with a movable groove 13. The movable groove 13 is slidably connected to the limiting ring 14. The limiting ring 14 is fixedly connected to the outer wall surface of the corresponding limiting block 10. The outer diameter of the limiting ring 14 is larger than the aperture of the connecting hole 9. The movable groove 13 is provided with a spring 15. The spring 15 is movably sleeved on the corresponding limiting block 10. The spring 15 is located above the limiting ring 14. Two limiting holes 8 are provided on the connecting block 7 at positions corresponding to the two limiting blocks 10. The end of the limiting block 10 located in the connecting groove 6 can be slidably inserted into the limiting hole 8.

[0028] A shift block 11 is disposed above the baffle 4 at positions corresponding to the two limit blocks 10 , and the tops of the two limit blocks 10 are fixedly connected to the lower wall surface of the shift block 11 .

[0029] When in use, the staff first lifts the shift block 11 upwards. At this time, the limit block 10 moves upward inside the connecting hole 9. The limit ring 14 moves upward with the limit block 10 inside the movable groove 13, and the spring 15 is deformed by force until the lower end of the limit block 10 enters the inside of the connecting hole 9. Then the connecting block 7 can be inserted into the inside of the corresponding connecting groove 6, so that the limit hole 8 on the connecting block 7 corresponds to the connecting hole 9 up and down. At this time, the staff releases the shift block 11, and the limit block 10 will move downward under the action of the elastic force of the spring 15 and enter the inside of the corresponding limit hole 8, thereby completing the clamping and fixing of the connecting block 7, achieving the effect of quickly assembling the shaping plate 5 and the baffle 4 together. At the same time, when the back of the platform at the corner of the road is cast, the shift block 11 can be lifted again to separate the limit block 10 from the inside of the limit hole 8, thereby completing the quick disassembly of the shaping plate 5 and the baffle 4.

[0030] Auxiliary grooves 12 are provided below both the front and rear ends of the shifting block 11 , and the auxiliary grooves 12 are rectangular notches.

[0031] By providing auxiliary grooves 12 below the front and rear ends of the shift block 11, a better point of force is provided for the operator to operate, thereby further improving the convenience of device operation.

[0032] Two T-shaped slots 16 are provided on the left side wall surface of the baffle plate 4 at positions corresponding to the lower ends of the two connecting columns 3, and a T-shaped slider 17 is movably clamped inside the two T-shaped slots 16, and the side wall surface of the T-shaped slider 17 away from the baffle plate 4 is fixedly connected to the side wall surface adjacent to the corresponding connecting column 3, and a threaded hole 18 is provided at a position corresponding to the T-shaped slider 17 on one of the connecting columns 3, and a bolt 19 is connected to the internal thread of the threaded hole 18, and the end of the bolt 19 close to the baffle plate 4 passes through the interior of the T-shaped slider 17 and contacts with the inner wall surface of the corresponding T-shaped slot 16.

[0033] When in use, the two connecting columns 3 connect the baffle plate 4 through the T-shaped slider 17 and the T-shaped slot 16. Since one of the connecting columns 3 is threadedly connected with a bolt 19, and the bolt 19 passes through the corresponding T-shaped slider 17 and contacts the inner wall surface of the corresponding T-shaped slot 16, when pouring the platform back at the corner of the road, when it is necessary to adjust the platform back width at the other end, the staff can turn the bolt 19 to separate it from the inner wall surface of the T-shaped slot 16. At this time, the position of the baffle plate 4 can be moved forward and backward. After adjusting the position of the baffle plate 4, the position of the baffle plate 4 can be fixed again by turning the bolt 19. In this way, the adjustment of the platform back width at the other end can be completed, thereby improving the practicality of the equipment.

[0034] The L-shaped structure of the shaping plate 5 can also be provided with an arc-shaped fillet. The shaping plate 5 is provided with an arc-shaped fillet to meet the requirement that the road corner is an arc shape, thereby improving the practicality of the device.
