Description

Technical Field

[0001] The invention relates to the technical field of concrete elevation control construction, in particular to a bridge concrete leveling layer elevation control device. Background Art

[0002] Municipal landscape bridges, as urban landscape elements and scenic lines, demand high aesthetic standards. The bridge deck, a key component of landscape bridges, requires strict control of flatness and elevation to achieve both scenic effects and drainage functions. As the concrete leveling layer between the bridge box girder and the bridge deck, proper pouring of the concrete leveling layer is crucial to controlling flatness and elevation.

[0003] Due to the aesthetic requirements of municipal landscape bridges, they are often designed as irregular shaped bridges with different deck elevation requirements. Conventional pouring of concrete screeds is difficult to control the pouring shape and elevation. In addition, concrete pouring at night is common in cities, making it even more difficult to control the pouring of the screed. If the pouring effect is poor, it will lead to problems such as uneven bridge decks, cracks, and excessive concrete usage.

[0004] Before pouring the conventional leveling concrete, plaster cakes are placed at closely spaced intervals along the bridge's centerline to control the centerline elevation. A chalk line is then drawn along the length of the ground sheet to control the elevation on both sides, ultimately controlling the overall surface elevation and slope. This makes it difficult to observe the plaster cakes and chalk lines during concrete pouring, and smoothing the slope is difficult, making the overall construction process time-consuming and labor-intensive, with poor results.

[0030] See also Figure 1 and 2 The present invention provides a bridge concrete leveling layer elevation control device, comprising:

[0031] The first base plate 10 and the second base plate 20 of the same structure are connected to form an angle, and the angle of the connection is adjustable. Specifically, the first base plate 10 and the second base plate 20 are respectively provided with an arc sleeve and an arc support rod, and the arc support rod is fixed by a locking bolt;

[0032] There are two side baffles 40, which are respectively arranged on opposite sides of the connecting end of the first bottom plate 10 and the second bottom plate 20 and are adjustable in angle therewith. At least two pulleys 50 are provided on the upper part of the outer surface of the side baffles 40;

[0033] There are two front baffles 60, which are respectively arranged at one end of the first bottom plate 10 and the second bottom plate 20, and a middle baffle 70 is arranged between the two front baffles 60;

[0034] One end of the operating lever 30 is connected to the first base plate 10 and the second base plate 20 , and the other end is tilted toward the side where the front baffle 60 is provided.

[0035] This embodiment is specifically applied to the construction of pedestrian bridges. When smoothing the concrete and controlling the elevation of the bridge deck, the traditional method is to place mortar cakes at intervals in the middle of the bridge and draw chalk lines on the ground to control the elevation. However, after pouring the concrete, the mortar cakes and chalk lines are difficult to observe when smoothing, and the slope smoothing is difficult to operate because the bridge deck is set on a slope to avoid water accumulation on the bridge deck; please refer to Figure 5Through this technical solution, the first base plate 10 and the second base plate 20 are adjusted to a suitable angle in advance according to the construction requirements of the bridge, and are covered on the concrete of the bridge deck. The baffles 40 on both sides are fitted with the ground blanket, and the pulleys 50 set on both sides are placed on the ground blanket. By pulling the operating rod 30, the elevation control of the bridge deck concrete is completed, and the bridge deck concrete can also be smoothed with a slope. The operation is simple and quick, which improves construction efficiency.

[0036] In one embodiment, see Figure 2 and Figure 3 The first base plate 10 and the second base plate 20 both include a fixed plate 11, on which a slidable and retractable movable plate 12 is provided. The side baffle 40 includes a lower support plate 41 movably connected to the movable plate 12, and the lower support plate 41 is provided with a slidable and retractable upper support plate 42. The fixed plate 11 and the movable plate 12, the movable plate 12 and the lower support plate 41, and the lower support plate 41 and the upper support plate 42 are all fixed by fastening bolts.

[0037] The first bottom plate 10 is configured as a fixed plate 11 and a movable plate 12 to achieve a retractable function to meet the requirements of different bridge deck widths. Before use, the movable plate 12 is pulled outward or retracted inward according to the size of the bridge deck, so that the first bottom plate 10 completely covers the local transverse surface of the bridge deck; it should be noted that when the fixed plate 11 and the movable plate 12 are set, the distance between the bottom surface of the movable plate 12 and the bottom surface of the fixed plate 11 is less than 0.5 cm so as not to affect the overall slope after leveling.

[0038] The movable plate 12 and the lower support plate 41 are rotatably connected by fastening bolts. After adjusting the angles of the first base plate 10 and the second base plate 20 according to the slope of the bridge deck, the angles of the lower support plate 41 and the movable plate 12 are adjusted synchronously so that the lower support plate 41 is in a vertical state, which facilitates close fit with the bridge floor when in use.

[0039] The lower support plate 41 and the upper support plate 42 are retractable, so that the height of the side baffle 40 can be adjusted according to the bridge deck concrete elevation required by the construction. When the device is in use, when the pulley 50 is placed on the ground burden, the lower surfaces of the first base plate 10 and the second base plate 20 are in contact with the bridge deck concrete, and then the subsequent pulling device is moved to complete the control and leveling of the bridge deck concrete elevation.

[0040] In one embodiment, see Figure 4 The front baffle 60 includes a main support plate 61 detachably connected to the fixed plate 11 and a sub-support plate 65 movably inserted on the main support plate 61 and the lower support plate 41. The sub-support plate 65 is fitted with the end of the movable plate 12, and the connecting end of the sub-support plate 65 and the lower support plate 41 is a slope structure. A rectangular groove is opened on the lower support plate 41, and the bottom of the sub-support plate 65 is flush with the bottom surface of the movable plate 12.

[0041] The setting of the front baffle 60 can push the excess concrete in the moving direction of the device when the device is pulled as a whole, and keep the bridge deck concrete in a flat state after the device moves. The setting of the main support plate 61 and the auxiliary support plate 65 is convenient for adapting to the fixed plate 11 and the movable plate 12 adjusted according to bridges of different sizes, so that the bridge deck concrete can be comprehensively elevated and smoothed after the device is adjusted.

[0042] In one embodiment, see Figure 4 An integrally formed U-shaped convex plate 66 is provided on the main support plate 61. The two ends of the U-shaped convex plate 66 are flush with the two ends of the main support plate 61, and a leakage port 63 is opened at the bottom of the U-shaped convex plate 66. One end of the leakage port 63 is flush with the outer surface of the main support plate 61. A movable baffle plate 64 is provided in the inner cavity of the main support plate 61. The baffle plate 64 is L-shaped and the bottom end can be moved outward in the main support plate 61 to extend and block the leakage port 63 from the upper end.

[0043] Through the setting of the U-shaped protrusion 66, when the device is pushed along the bridge deck, the lower edge of the U-shaped protrusion 66 will scoop up the excess concrete that is higher than the concrete elevation of the bridge deck. When the amount of excess concrete is large, the main support plate 61 is removed from the first bottom plate 10 to clean up the excess concrete and reduce the resistance during the movement. In order to avoid the concrete in some local areas being lower than the elevation, a leakage port 63 is provided. During the accumulation of excess concrete, if the device moves to a position where the concrete is lower than the elevation, the scooped excess concrete will automatically leak out from the leakage port 63 to fill the missing areas and ensure the overall flatness of the bridge deck concrete.

[0044] In one embodiment, see Figure 2 The bottom surface of the main support plate 61 is flush with the bottom surfaces of the corresponding first and second bottom plates 10, 20. At least two insertion rods 62 are provided on the surface of the main support plate 61, which are movably connected to the corresponding first and second bottom plates 10, 20. A handle (not numbered in the figure) is provided on the upper surface of the main support plate 61. The provision of the insertion rods 62 allows for easy removal of the main support plate 61 from the first bottom plate 10, improving the efficiency of removal and carrying after cleaning excess concrete or after use.

[0045] In one embodiment, see Figure 3The movable plate 12 is provided with a bar frame 44, and the lower support plate 41 is provided with an oblique support rod 43 connected to the bar frame 44 at one end and capable of rotation. The other end of the oblique support rod 43 is movably connected to the bar frame 44 and has an integrally formed protrusion that passes through the bar frame 44. The protrusion is provided with a threaded sleeve for fixing. The provision of the oblique support rod 43 facilitates strengthening the connection strength between the lower support plate 41 and the movable plate 12 after the angle between the lower support plate 41 and the movable plate 12 is adjusted. This prevents the lower support plate 41 from easily rotating toward the movable plate 12 during movement. In addition, during the adjustment process between the lower support plate 41 and the movable plate 12, the protrusion at the end of the oblique support rod 43 slides accordingly along the bar frame 44 to adapt to the position change between the two during the adjustment process.

[0046] In one embodiment, see Figure 4 The ends of the central baffle 70 partially overlap with the front baffles 60 on either side. Mounting rods 71 ​​are provided on the surface of the central baffle 70 for flexible insertion into the front baffles 60. Evenly spaced arc-shaped holes are provided on the surface of the front baffles 60 to accommodate the mounting rods 71. The bottom surface of the central baffle 70 and the lines closest to the fulcrums of the two front baffles 60 are coplanar. The provision of mounting rods 71 ​​allows the central baffle 70 to be removable while also adapting to the gap between the first and second base plates 10, 20 after adjustment, ensuring full advancement of the bridge deck concrete.

[0047] In one embodiment, the secondary support plate 65 is provided with an integrally formed protrusion, and the outer surface of the side panel 40 is provided with grooves that sequentially mate with the protrusion provided on the secondary support plate 65, the carrying handle provided on the main support plate 61, and the mounting rod 71 provided on the center panel 70. This arrangement facilitates the sequential removal of the main support plate 61, secondary support plate 65, and center panel 70 after use, and their subsequent positional insertion into the lower support plate 41. Simultaneously, the side panel 40 is moved as close as possible to the first base plate 10 or the second base plate 20, and the first base plate 10 and the second base plate 20 are moved closer together, thereby reducing the overall volume and facilitating handling and portability.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
