Description

Technical Field

[0001] This utility model relates to the field of road construction equipment, and in particular to a concrete pouring device for curb backrests. Background Technology

[0002] As a key load-bearing and protective structure at the edge of a road, the quality of the concrete backing of the curbstone directly determines the overall stability, driving safety, and service life of the road. During road construction, the concrete backing needs to form a support system that is tightly fitted to the curbstone to restrain lateral displacement and distribute the load.

[0003] Chinese utility model patent CN114481763A discloses a curbstone backrest concrete formwork device and its construction method. The curbstone backrest concrete formwork device includes a main formwork, a telescopic support frame, bidirectional adjusting screws, and a bottom rolling wheel assembly. The main formwork is formed by bending steel plates, and the support frame is composed of multiple sleeve sections. The adjusting screws are respectively set horizontally and vertically to adjust the spacing and height of the formwork. The rolling wheel assembly is installed at the four corners of the bottom of the support frame. In use, the device is first hoisted to the preset position on the curbstone. The relative position of the main formwork and the curbstone is calibrated and locked using the adjusting screws. Concrete is then injected into the pouring cavity between the formwork and the curbstone. After the initial setting of the single section of concrete, the device is moved to the next construction area via the rolling wheel assembly.

[0004] However, the above-mentioned existing technologies still have certain defects: when the device moves along the length of the curbstone, it is easily affected by factors such as the flatness deviation of the curbstone surface during construction or the traction force, resulting in lateral displacement, which in turn leads to fluctuations in the width of the pouring area and poor edge regularity. Utility Model Content

[0005] This application provides a curbstone back concrete pouring device, which solves the problem in the prior art that the curbstone back concrete pouring device is prone to lateral displacement when moving, resulting in fluctuations in the width of the pouring area and poor edge regularity.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a curbstone backrest concrete pouring device, comprising a backrest concrete steel formwork and two template side Z-direction inner tubes fixed to the backrest concrete steel formwork. Template side Z-direction outer tubes are nested and installed outside the two template side Z-direction inner tubes. A sleeve is fixedly connected to the same side of the two template side Z-direction outer tubes. The sleeve includes two Y-direction inner tubes perpendicular to the template side Z-direction outer tubes and a Y-direction outer tube nested outside the Y-direction inner tubes. A curbstone top roller is rotatably installed at the bottom of each of the two Y-direction outer tubes. The ends of the two Y-direction outer tubes away from the backrest concrete steel formwork are connected via X-direction tubes. Curbstone side Z-direction inner tubes are vertically installed at both ends of the X-direction tubes near the Y-direction outer tubes. A curbstone side roller is rotatably installed on the side of the curbstone side Z-direction inner tubes close to the curbstone.

[0007] Because this device is equipped with a top roller of the curb that rotates to the bottom of the Y-direction outer pipe, and a side roller of the curb that rotates to the side of the curb that rotates to the side of the curb that is close to the curb, the top roller of the curb can roll against the top surface of the curb and the side roller of the curb can roll against the side of the curb when the device is in use. This forms a double limiting guide for the movement of the device, thereby solving the problem in the prior art that when the device moves along the length of the curb, it is easily affected by factors such as the flatness deviation of the curb surface during construction or the traction force, resulting in lateral displacement, which in turn leads to fluctuations in the width of the pouring area and poor edge regularity.

[0008] As a further improvement to the above solution, the two ends of the X-direction tube are respectively vertically fixed with the Z-direction outer tube on the curb side near the Y-direction outer tube, and the upper end of the Z-direction inner tube on the curb side is embedded in the interior of the Z-direction outer tube on the curb side; thereby, the height of the curb side roller can be flexibly adjusted to ensure that it can always fit tightly with the curb side of different height specifications, and ensure the limiting and guiding effect when the device moves.

[0009] As a further improvement to the above solution, both sides of the Z-direction outer tubes on the curb side are threaded with a No. 1 screw. One end of the No. 1 screw penetrates into the interior of the Z-direction outer tube on the curb side and can be pressed against the side of the Z-direction inner tube on the curb side. Thus, after the height of the roller on the curb side is adjusted to the correct position, the position of the Z-direction inner tube on the curb side can be fixed by tightening the No. 1 screw.

[0010] As a further improvement to the above scheme, each Z-direction outer tube on the template side is threaded with a No. 2 screw. One end of the No. 2 screw penetrates into the interior of the Z-direction outer tube on the template side and can be tightened against the side of the Z-direction inner tube on the template side. Thus, after the height of the back concrete steel template is adjusted to the correct position, the relative position of the Z-direction inner tube and the outer tube on the template side can be fixed by tightening the No. 2 screw.

[0011] As a further improvement to the above solution, each Y-shaped outer pipe has a threaded screw at position three on its side. One end of the screw at position three penetrates into the interior of the Y-shaped outer pipe and can be tightened against the side of the Y-shaped inner pipe. Thus, after the distance between the back concrete steel formwork and the curbstone is adjusted to the correct position, the relative position of the Y-shaped inner pipe and the outer pipe can be fixed by tightening the screw at position three, effectively preventing the width of the pouring cavity from shifting due to concrete lateral pressure or vibration during construction.

[0012] As a further improvement to the above scheme, each Z-direction outer tube on the template side is threaded with at least two No. 2 screws, and each Y-direction outer tube is threaded with at least two No. 3 screws. This can disperse the tightening force on the Z-direction inner tube and Y-direction inner tube on the template side, making the fixation of the two more secure and the force more even, effectively avoiding the displacement of the inner tube due to vibration or concrete lateral pressure during construction.

[0013] As a further improvement to the above solution, one end of each of the No. 1, No. 2, and No. 3 screws is provided with a pentagonal handle; thus, the operator can easily hold and rotate the screws to complete the adjustment and fixing of each telescopic structure without the need for additional tools.

[0014] As a further improvement to the above solution, the axial dimension of the top roller and the side roller of the curbstone is not less than its own radial dimension; this can make the rollers bear more even force, reduce the pressure on the surface of the curbstone to avoid damaging the curbstone, and at the same time improve the adhesion stability between the roller and the curbstone.

[0015] As a further improvement to the above solution, the top roller and the side roller of the curb are both solid rubber rollers; this can buffer the vibration generated when the device moves, and at the same time enhance the fit between the roller and the surface of the curb to avoid slippage.

[0016] As a further improvement to the above solution, at least one Y-shaped outer tube is also rotatably mounted with a handle, which is T-shaped and has a length of not less than 20cm; thus, the operator can easily push the device along the curb without bending over, improving the ease of movement of the device.

[0017] As can be seen from the above technical solutions, this utility model has at least the following technical effects or advantages: Because this device is equipped with a top roller of the curb that rotates to the bottom of the Y-direction outer pipe, and a side roller of the curb that rotates to the side of the curb that rotates to the side of the curb that is close to the curb, the top roller of the curb can roll against the top surface of the curb and the side roller of the curb can roll against the side of the curb when the device is in use. This forms a double limiting guide for the movement of the device, thereby solving the problem in the prior art that when the device moves along the length of the curb, it is easily affected by factors such as the flatness deviation of the curb surface during construction or the traction force, resulting in lateral displacement, which in turn leads to fluctuations in the width of the pouring area and poor edge regularity.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this patent.

[0020] This utility model discloses a device for pouring concrete for curb backrests, such as... Figure 3As shown, it includes a backrest concrete steel formwork 1 and two Z-direction inner tubes 2 fixed to the backrest concrete steel formwork 1. A Z-direction outer tube 3 is nested around the outside of each of the two Z-direction inner tubes 2. A sleeve is fixedly connected to the same side of each of the two Z-direction outer tubes 3. The sleeve includes two Y-direction inner tubes 4 perpendicular to the Z-direction outer tubes and a Y-direction outer tube 5 nested around the outside of the Y-direction inner tubes 4. A top roller 6 for the curb stone is rotatably installed at the bottom of each of the two Y-direction outer tubes 5. The ends of the two Y-direction outer tubes 5 away from the backrest concrete steel formwork 1 are connected via an X-direction tube 7. A Z-direction inner tube 8 for the curb stone is vertically installed at both ends of the X-direction tube 7 near the Y-direction outer tubes 5. A side roller 9 for the curb stone is rotatably installed on the side of the Z-direction inner tube 8 closest to the curb stone.

[0021] In this embodiment, the backrest concrete steel formwork 1 is formed by bending high-strength steel plates, which has high flatness and strong load-bearing capacity, ensuring that the formwork is not easily deformed during concrete pouring and ensuring the quality of the backrest concrete molding. The lower parts of the two Z-direction inner tubes 2 on the formwork side are welded and fixed to the backrest concrete steel formwork 1 and are set in a vertical direction. The outer diameter of the Z-direction inner tube 2 on the formwork side is adapted to the inner diameter of the Z-direction outer tube 3 on the formwork side, so that the Z-direction inner tube 2 on the formwork side can slide up and down along the axis of the Z-direction outer tube 3 on the formwork side, realizing the height adjustment of the backrest concrete steel formwork 1. The sleeve is fixed to the two Z-direction outer tubes 3 on the formwork side by welding. The two Y-direction inner tubes 4 in the sleeve are set horizontally and perpendicular to the Z-direction outer tubes 3 on the formwork side. The outer diameter of the Y-direction inner tube 4 matches the inner diameter of the Y-direction outer tube 5, which can realize Y-direction telescopic adjustment. The bottom of the Y-shaped outer tube 5 is rotatably mounted with a curb top roller 6 via a pivot. The roller can roll along the top surface of the curb, reducing friction when the device moves. The ends of the two Y-shaped outer tubes 5 away from the back concrete steel formwork 1 are welded and fixed by the X-shaped tube 7 to form a stable frame structure. The two ends of the X-shaped tube 7 are vertically connected to the curb side Z-shaped inner tube 8 near the Y-shaped outer tube 5. The curb side Z-shaped inner tube 8 is vertical, and the side of it close to the curb is rotatably mounted with a curb side roller 9 via a pivot. The curb side roller 9 can fit against the side of the curb.

[0022] In actual construction, the entire device is first placed at the pre-set construction position of the curbstone, so that the top roller 6 of the curbstone is in contact with the top surface of the curbstone, and the side roller 9 of the curbstone is in contact with the side of the curbstone. The height of the back concrete steel formwork 1 is adjusted by the nesting cooperation of the Z-direction inner tube 2 and the Z-direction outer tube 3 on the formwork side, and the distance between the back concrete steel formwork 1 and the curbstone is adjusted by the nesting cooperation of the Y-direction inner tube 4 and the Y-direction outer tube 5, ensuring that the size of the pouring cavity meets the construction requirements. After the adjustment is completed, concrete is injected into the pouring cavity between the back concrete steel formwork 1 and the curbstone. After the single section of concrete is poured and initially set, the device is pushed, and the top roller 6 of the curbstone rolls along the top of the curbstone, and the side roller 9 of the curbstone rolls along the side of the curbstone, driving the device to move smoothly to the next construction area. The above steps are repeated to complete the subsequent pouring operation.

[0023] In the above structure, by setting the top roller 6 and the side roller 9 of the curbstone, the device is guided by the double limiting of the top and side of the curbstone when it moves, which effectively avoids the problem of lateral displacement that is easy to occur when the device moves in the prior art, ensures the consistency of the width of the pouring area, and improves the regularity of the back concrete edge. At the same time, the nesting cooperation of the Z-direction inner pipe 2 and the Z-direction outer pipe 3 on the template side, and the Y-direction inner pipe 4 and the Y-direction outer pipe 5 on the template side, realizes the flexible adjustment of the height and width of the pouring cavity, adapts to the construction needs of curbstones of different specifications, and improves the versatility of the device.

[0024] Furthermore, at both ends of the X-direction tube near the Y-direction outer tube 5, a curb-side Z-direction outer tube 10 is vertically fixed, and the upper end of the curb-side Z-direction inner tube 8 is embedded inside the curb-side Z-direction outer tube 10. In this embodiment, the curb-side Z-direction outer tube 10 is vertically welded to both ends of the X-direction tube 7, and its inner diameter is adapted to the outer diameter of the curb-side Z-direction inner tube 8. The upper end of the curb-side Z-direction inner tube 8 can slide up and down along the axial direction of the curb-side Z-direction outer tube 10, thereby realizing the adjustment of the height direction of the curb-side roller 9, ensuring that the curb-side roller 9 can always be tightly fitted with the curb side of different height specifications, and ensuring the limiting and guiding effect.

[0025] Both of the Z-direction outer tubes 10 on the curb side are threadedly fitted with a No. 1 screw 11. One end of the No. 1 screw 11 penetrates into the interior of the Z-direction outer tube 10 on the curb side and can be pressed against the side of the Z-direction inner tube 8 on the curb side. In this embodiment, the No. 1 screw 11 is connected to the side of the Z-direction outer tube 10 on the curb side through a threaded hole. One end of the No. 1 screw 11 extends into the interior of the Z-direction outer tube 10 on the curb side, while the other end is located on the outside for easy operation. After the height of the curb side roller 9 is adjusted to a suitable position, the No. 1 screw 11 is rotated so that its extended end presses against the side of the Z-direction inner tube 8 on the curb side. The position of the Z-direction inner tube 8 on the curb side is fixed by friction, preventing the Z-direction inner tube 8 on the curb side from shifting due to vibration during construction or when the device is moved, thus ensuring the stability of the limiting position.

[0026] Each Z-direction outer tube 3 on the template side is threaded with a second-position screw 12. One end of the second-position screw 12 penetrates into the interior of the Z-direction outer tube 3 on the template side and can be tightened against the side of the Z-direction inner tube 2 on the template side. In this embodiment, the second-position screw 12 is threaded into the threaded hole on the side of the Z-direction outer tube 3 on the template side. After the height of the backrest concrete steel template 1 is adjusted to the correct position, the second-position screw 12 is rotated so that its extended end is tightened against the side of the Z-direction inner tube 2 on the template side, fixing the relative position of the Z-direction inner tube 2 and the outer tube on the template side. This prevents the template height from changing during the pouring process and ensures that the pouring height of the backrest concrete meets the design requirements.

[0027] Each Y-direction outer pipe 5 has a threaded connection to a No. 3 screw 13 on its side. One end of the No. 3 screw 13 penetrates into the interior of the Y-direction outer pipe 5 and can be tightened against the side of the Y-direction inner pipe 4. In this embodiment, the No. 3 screw 13 is threaded into the threaded hole on the side of the Y-direction outer pipe 5. After the distance between the backrest concrete steel formwork 1 and the curbstone is adjusted to the correct position, the No. 3 screw 13 is rotated so that its extended end is tightened against the side of the Y-direction inner pipe 4, fixing the relative position of the Y-direction inner pipe 4 and the outer pipe. This prevents changes in the width of the pouring cavity during construction and ensures that the thickness of the backrest concrete is uniform.

[0028] Each Z-direction outer tube 3 on the template side has at least two threaded screws 12 in position 2, and each Y-direction outer tube 5 has at least two threaded screws 13 in position 3. In this embodiment, the two threaded screws 12 in position 2 on the Z-direction outer tube 3 are spaced apart vertically, and the two threaded screws 13 in position 3 on the Y-direction outer tube 5 are spaced apart horizontally. The arrangement of multiple screws can distribute the tightening force, making the fixing of the Z-direction inner tube 2 and the Y-direction inner tube 4 on the template side more secure and the force more even, further preventing them from shifting during construction and improving the overall structural stability and reliability of the device.

[0029] Each of the three screws, namely screw 12 (position 1) and screw 13 (position 3), has a pentagonal handle at one end. In this embodiment, the pentagonal handle is fixed to the end of the screw by welding or integral molding. The surface of the pentagonal handle has anti-slip texture, allowing the operator to easily rotate the screw by holding the pentagonal handle to achieve adjustment and fixing without the need for additional tools. This simplifies the construction process and improves operational convenience and construction efficiency.

[0030] The axial dimensions of both the top curb roller 6 and the side curb roller 9 are not less than their radial dimensions. In this embodiment, the axial lengths of the top curb roller 6 and the side curb roller 9 are relatively long, increasing the contact area between the rollers and the curb surface. This structure allows for more even force distribution on the rollers, reducing pressure on the curb surface and preventing damage. It also improves the adhesion stability between the rollers and the curb, further ensuring the guiding accuracy of the device during movement.

[0031] The top roller 6 and side roller 9 of the curb are both solid rubber rollers. In this embodiment, the solid rubber material has good elasticity and wear resistance, which can buffer the vibration generated when the device moves and reduce noise. At the same time, the rubber material has high friction, which can enhance the adhesion between the roller and the curb surface, avoid slippage, ensure the stability and guiding accuracy of the device during movement, and the solid structure makes the roller have a stronger load-bearing capacity and a longer service life.

[0032] At least one Y-direction outer tube 5 is rotatably mounted with a handle 14, which is T-shaped and at least 20cm long. In this embodiment, the handle 14 is rotatably mounted on the side of the Y-direction outer tube 5 via a pivot. The T-shaped structure facilitates two-handed gripping by the operator, and the length of at least 20cm conforms to ergonomic design, allowing the operator to easily move the device without bending over. The handle 14 can rotate around the pivot and can be rotated to fit against the Y-direction outer tube 5 when not in use, reducing space occupation and facilitating the storage and transportation of the device.

[0033] The working principle of this device is as follows: the nesting and cooperation of the Z-direction inner tube 2 and the Z-direction outer tube 3 on the template side can adjust the height of the back concrete steel template 1; the nesting and cooperation of the Y-direction inner tube 4 and the Y-direction outer tube 5 can adjust the distance between the back concrete steel template 1 and the curb; the cooperation of the Z-direction inner tube 8 and the Z-direction outer tube 10 on the curb side can adjust the height of the curb side roller 9, thus adapting to the pouring requirements of curbs of different specifications; after adjustment, the corresponding inner tubes are tightened by the first screw 11, the second screw 12, and the third screw 13 respectively to fix each telescopic structure and ensure the stability of the pouring cavity size; with the help of the contact and limiting of the curb top roller 6 with the curb top and the curb side roller 9 with the curb side, the device moves smoothly along the length of the curb, avoiding lateral displacement; the operator pushes the device through the T-shaped handle 14, and after the single-section pouring is completed, it moves to the next construction area to continuously complete the continuous pouring operation of the curb back concrete.
