Description

Technical Field

[0001] This invention relates to a steel mesh positioning and paving device, and more particularly to a steel mesh positioning and paving device for bridge deck paving. Background Technology

[0002] Reinforcing mesh is a mesh of longitudinal and transverse steel bars arranged at certain intervals and at right angles, with the steel bars fixed together. Its emergence is of great significance for improving construction efficiency, structural quality and safety reliability, and changing traditional construction methods. In the process of bridge construction, reinforcing mesh is usually laid on the formwork of the bridge deck before concrete is poured.

[0003] In existing bridge steel reinforcement mesh, weaving and pouring are mostly done manually. When the steel bars are moved, the weaving spacing is easily substandard, and there is a lack of auxiliary positioning mechanisms. At the same time, during the pouring process, the steel reinforcement mesh is generally placed directly on the surface of the formwork. However, during pouring, the steel reinforcement mesh needs to be placed at a certain distance from the formwork. Usually, stones are used to support it. The steel reinforcement mesh is heavy, and it is not easy to place the stones. It is necessary to use a pry bar to lift it, which is quite troublesome. In addition, the stones can roll away, which can easily cause the steel bars to come into contact with the formwork surface. This can easily lead to exposure after pouring, affecting the quality of the project. Summary of the Invention

[0004] The purpose of this invention is to provide a bridge deck pavement steel mesh positioning and paving device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bridge deck pavement steel mesh positioning and paving device, comprising a housing and an insertion mechanism connected to the housing, the insertion mechanism comprising insert plates, insert plates slidably connected to both sides of the bottom end of the housing, a first spring abutting between the insert plates and the housing, a push rod slidably connected to each insert plate inside the housing via an axis, the bottom end of the push rod being rotatably connected to the insert plate, the push rod and the insert plate being arranged in an "L" shape, a pressing rod slidably connected to the top of the housing, the inner side of the pressing rod abutting against the outer side of the push rod, the end of the pressing rod abutting against the inner side of the push rod tilting inwards towards the top, a lifting mechanism for lifting the housing connected to the housing, and a control mechanism for limiting the movement connected to the housing.

[0006] With the above technical solution, pressing the actuating rod causes it to slide into the interior of the housing. The actuating rod then pushes the push rod to rotate towards the center of the housing. The bottom of the push rod will push the insert plate in the opposite direction to extend towards the steel sheet. The first spring will be compressed, and the insert plate will be inserted into the bottom of the inverted steel bar, thus facilitating the lifting mechanism to lift it.

[0007] As a preferred embodiment of the present invention, the push rod is in the shape of "[", and the pair of push rods are arranged in an inverted "V" shape. The top of the push rod is rotatably connected to an abutment wheel, and the push rod rolls against the inner inclined surface of the push rod through the abutment wheel.

[0008] The above technical solution enables a pair of push rods to rotate simultaneously when the push rod is pressed, thus facilitating the ejection of the insert plate.

[0009] As a preferred embodiment of the present invention, the sliding end of the push rod is close to the insert plate, and the ends of the pair of insert plates that are opposite to each other are inclined.

[0010] The above technical solution creates a lever, increases the force pushing the insert plate, and allows the insert plate to pass through the bottom of the reinforcing bar.

[0011] As a preferred embodiment of the present invention, the lifting mechanism includes a ratchet and a gear. The ratchet is rotatably connected inside the housing, and a coaxial gear is fixedly connected to the ratchet. A grip and a lifting block are slidably connected to the top and bottom of the housing, respectively. A first rack is installed on one side of the bottom end of the grip, and a sixth spring is installed between the grip and the housing. The first rack and the ratchet mesh in one direction. A pushing assembly is connected between the grip and the housing. A second rack is installed on the top end of the lifting block near the gear, and the second rack meshes with the gear. A pawl is rotatably connected inside the housing, and a torsion spring abuts against the pawl and the housing. The torsion spring pushes the pawl to mesh with the ratchet. The control mechanism is connected to the pawl.

[0012] Through the above technical solution, the grip lever will pull the ratchet to rotate through the first rack. The ratchet is controlled to rotate in one direction by the pawl. By repeatedly pressing the grip lever, the ratchet will be driven to rotate, which in turn drives the gear to rotate, driving the second rack and the lifting block to move downward, thereby extending out of the bottom of the shell and supporting the shell. This allows the reinforcing steel to be lifted through the insert plate, thus avoiding the reinforcing steel from contacting the surface of the formwork during the pouring process.

[0013] As a preferred embodiment of the present invention, the grip bar has an inverted "L" shape, the housing has a through window at the grip bar, the lifting block has an "L" shape, and a fourth spring is installed between the lifting block and the housing.

[0014] The above technical solution facilitates repeated pulling of the lever and allows the lifting block to be reset via the fourth spring.

[0015] As a preferred embodiment of the present invention, the pushing component includes a slider, and the housing is slidably connected to the slider on the side of the grip bar away from the ratchet. A fifth spring is installed between the slider and the housing, and the fifth spring pushes the slider to slide against the grip bar.

[0016] Through the above technical solution, the first rack at the bottom end of the grip rod can be kept engaged with the ratchet wheel, facilitating driving.

[0017] As a preferred technical solution of the present invention, the control mechanism includes a swing rod, the swing rod is rotatably connected inside the housing, a limiting block is slidably connected to the housing at the pressing rod position, a second spring is abutted between the limiting block and the housing, a limiting groove corresponding to the limiting block is provided on the side wall of the pressing rod, a pulling rod is fixedly connected to the top end of the swing rod, the pulling rod is slidably connected to the bottom end of the limiting block, a control rod is slidably connected to the swing rod, the control rod is slidably connected to the housing, a pushing block is slidably connected to the outer wall of the housing, and one end of the control rod is fixedly connected to the pushing block.

[0018] Through the above technical solution, it is convenient to limit the pressing rod, avoiding the insertion plate from sliding into the interior of the housing during use.

[0019] As a preferred technical solution of the present invention, the swing rod has a ">"-shaped structure, a抵触杆 (abutting rod) is fixedly connected to the bottom end of the swing rod, and one end of the抵触杆 (abutting rod) abuts against the side of the ratchet pawl close to the ratchet wheel.

[0020] Through the above technical solution, the one-way limit of the ratchet pawl can be released by the抵触杆 (abutting rod).

[0021] As a preferred technical solution of the present invention, a抵触机构 (abutting mechanism) is connected to the housing, the抵触机构 (abutting mechanism) includes a sliding frame, the housing has an inverted "凸" (convex)-shaped structure, sliding frames are slidably connected to both internal sides of the housing, a plurality of protruding steel sheets are slidably connected inside the sliding frames, a third spring is installed between the steel sheets and the sliding frames, a screw rod is rotatably connected to the housing at each sliding frame position, the screw rod is threadedly connected to the sliding frame, the bottoms of the plurality of steel sheets are flush with each other, and the bottom of the steel sheet is flush with the insertion plate.

[0022] Through the above technical solution, it is convenient to limit the movement of the steel bar, facilitate the insertion plate to be inserted under the steel bar, and avoid the steel bar from sliding and falling on the insertion plate.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. This invention uses a steel sheet, a housing, and a screw. Rotating the screw drives the sliding frame to slide, which in turn moves the steel sheet. The bottom of the housing is inserted between a pair of reinforcing bars, so that the bottom of the housing abuts against the template, and the pair of reinforcing bars are positioned exactly between a pair of steel sheets. There is a certain difference in the spacing between different pairs of reinforcing bars. The bottom end of the steel sheet will abut against the reinforcing bars, thereby pushing the steel sheet to slide into the sliding frame. The third spring is compressed, which facilitates the adaptation to the spacing between a pair of reinforcing bars and prevents the reinforcing bars from moving to both sides, thus playing a certain positioning role and avoiding the problem of inconsistent spacing of the reinforcing mesh during installation.

[0025] 2. This invention, by setting up a pressing rod, a pushing rod, an insert plate, and a swinging rod, allows the user to press down on the pressing rod with the thenar eminence of their palm. The pressing rod slides into the interior of the housing, pushing the pushing rod to rotate towards the center of the housing. The bottom of the pushing rod pushes the insert plate in the opposite direction, extending it towards the steel plate. The first spring is compressed, and the insert plate inserts into the bottom of the reinforcing bar, thus lifting the reinforcing bar and achieving a limiting effect. The limiting block enters the limiting groove, thereby restricting the upward movement of the pressing rod and keeping the insert plate in the state of lifting the reinforcing bar. Pushing the pushing block causes the control rod to slide, which in turn causes the swinging rod to rotate. The swinging rod pulls the limiting block away from the limiting groove via the pulling rod, thus facilitating the reset of the pressing rod.

[0026] 3. This invention, by setting up a gripping rod, ratchet, gear, first rack, second rack, and lifting block, allows the gripping rod to pull the ratchet to rotate while holding the housing. The ratchet is controlled to rotate in one direction by the pawl. By repeatedly pressing the gripping rod, the ratchet is driven to rotate, which in turn drives the gear to rotate, driving the second rack and lifting block to move downwards. The fourth spring is stretched, extending out from the bottom of the housing and supporting it. This allows the reinforcing steel to be lifted by the insert plate, thus avoiding contact between the reinforcing steel and the formwork surface during the pouring process. The housing can be disassembled while pouring. When the housing needs to be disassembled, the push block is pushed, which drives the swing rod to rotate. The swing rod pushes the pawl and ratchet to disengage through the abutment rod, thus releasing the ratchet. The fourth spring then pulls the lifting block back to its original position.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-5 This invention provides a technical solution for a bridge deck pavement steel mesh positioning and installation device:

[0035] according to Figure 1 and Figure 2 As shown, a bridge deck pavement steel mesh positioning and installation device includes a housing 1 and an insertion mechanism 2 connected to the housing 1. The insertion mechanism 2 includes insertion plates 22. Insertion plates 22 are slidably connected to both sides of the bottom end of the housing 1. A first spring 23 abuts against the insertion plates 22 and the housing 1. Inside the housing 1, a push rod 24 is slidably connected to each insertion plate 22 via an axis. The bottom end of the push rod 24 is rotatably connected to the insertion plate 22. The push rod 24 and the insertion plate 22 are arranged in an "L" shape. A pressing rod 21 is slidably connected to the top of the housing 1. The inner side of the pressing rod 21 is connected to the push rod 24. The outer side of the push rod 21 is in contact with the inner side of the push rod 24, and the end of the push rod 21 is in contact with the inner top. The housing 1 is connected to a lifting mechanism 5 for lifting the housing 1. The housing 1 is also connected to a control mechanism 3 for limiting the position. Pressing the push rod 21 causes it to slide into the housing 1. The push rod 21 pushes the push rod 24 to rotate towards the middle of the housing 1. The bottom of the push rod 24 will push the insert plate 22 in the opposite direction to extend towards the steel plate 42. The first spring 23 will be compressed, and the insert plate 22 will be inserted into the bottom of the inverted steel bar, thus facilitating the lifting mechanism 5 to lift it.

[0036] The push rod 21 has a "[" shaped structure, and a pair of push rods 24 are arranged in an inverted "V" shape. The top of the push rod 24 is rotatably connected to a contact wheel 25. The push rod 24 rolls against the inner inclined surface of the push rod 21 through the contact wheel 25, so that when the push rod 21 is pressed, the pair of push rods 24 can be rotated at the same time, which makes it easier to push out the insert plate 22.

[0037] The sliding end of the push rod 24 is close to the insert plate 22. The ends of the pair of insert plates 22 that are opposite to each other are inclined, thus forming a lever, increasing the force of pushing the insert plate 22, so that the insert plate 22 can pass through the bottom of the reinforcing bar.

[0038] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a bridge deck pavement steel mesh positioning and installation device includes a lifting mechanism 5 comprising a ratchet 55 and a gear 58. The ratchet 55 is rotatably connected inside the housing 1, and a coaxial gear 58 is fixedly connected to the ratchet 55. The ratchet 55 can be configured to have a larger diameter than the gear 58 to achieve labor-saving purposes. A handle 51 and a lifting block 52 are slidably connected to the top and bottom of the housing 1, respectively. A first rack 54 is installed on one side of the bottom end of the handle 51. A sixth spring 8 is installed between the handle 51 and the housing 1. The first rack 54 and the ratchet 55 engage in one-way meshing. A pushing assembly connects the handle 51 and the housing 1. A second rack 58 is installed on the top of the lifting block 52 near the gear 58. 9. The second rack 59 and gear 58 mesh. A pawl 57 is rotatably connected inside the housing 1. A torsion spring 56 abuts against the housing 1. The torsion spring 56 pushes the pawl 57 to mesh with the ratchet 55. The control mechanism 3 is connected to the pawl 57. The grip 51 pulls the ratchet 55 to rotate through the first rack 54. The ratchet 55 is controlled to rotate in one direction through the pawl 57. By repeatedly pressing the grip 51, the ratchet 55 will rotate, thereby driving the gear 58 to rotate, driving the second rack 59 and the lifting block 52 to move downward, thereby extending out of the bottom of the housing 1 and supporting the housing 1. The reinforcing bar is then lifted through the insert plate 22, thereby avoiding contact between the reinforcing bar and the formwork surface during the pouring process.

[0039] The grip 51 has an inverted "L" shape. The housing 1 has a through window at the grip 51 to facilitate pressing the grip 51. The lifting block 52 has an "L" shape. A fourth spring 53 is installed between the lifting block 52 and the housing 1 to facilitate the reset of the lifting block 52.

[0040] The pushing assembly includes a slider 7. The housing 1 is slidably connected to the slider 7 on the side of the grip 51 away from the ratchet 55. A fifth spring 6 is installed between the slider 7 and the housing 1. The fifth spring 6 pushes the slider 7 to slide against the grip 51, so that the first rack 54 at the bottom of the grip 51 can remain engaged with the ratchet 55, which facilitates driving.

[0041] The control mechanism 3 includes a swing rod 37, which is rotatably connected inside the housing 1. A limit block 32 is slidably connected to the housing 1 at the push rod 21. A second spring 33 abuts between the limit block 32 and the housing 1. The side wall of the push rod 21 is provided with a limit groove 35 corresponding to the limit block 32. A pull rod 34 is fixedly connected to the top of the swing rod 37. The pull rod 34 is slidably connected to the bottom end of the limit block 32. A control rod 36 is slidably connected to the swing rod 37. The control rod 36 is slidably connected to the housing 1. A push block 31 is slidably connected to the outer wall of the housing 1. One end of the control rod 36 is fixedly connected to the push block 31, thereby facilitating the locking of the push rod 21.

[0042] The swing lever 37 has a ">" shaped structure. The bottom end of the swing lever 37 is fixedly connected to an abutment lever 38. One end of the abutment lever 38 abuts against the side of the pawl 57 near the ratchet 55, thereby facilitating the rotation of the pawl 57 to release the limit.

[0043] according to Figure 1 and Figure 2 As shown, a bridge deck pavement steel mesh positioning and paving device is provided. The housing 1 is connected to an abutment mechanism 4, which includes a sliding frame 44. The housing 1 has an inverted "U" shaped structure. The sliding frames 44 are slidably connected to the inside of both sides of the housing 1. Multiple protruding steel plates 42 are slidably connected inside the sliding frames 44. A third spring 43 is installed between the steel plates 42 and the sliding frames 44. A screw 41 is rotatably connected to each sliding frame 44 on the housing 1. The screw 41 is threadedly connected to the sliding frame 44. The steel plates 42 at both ends place a pair of steel bars between them, thereby restricting the movement of the steel bars.

[0044] The bottoms of multiple steel plates 42 are flush with each other, and the bottoms of the steel plates 42 are flush with the insert plate 22, which makes it easy to insert them into the bottom of the reinforcing bar.

[0045] In practical use, after the steel mesh is laid on the template of the bridge deck, it is tied with wire. The shell 1 is held by the through-groove, and the screw 41 is rotated. The screw 41 drives the sliding frame 44 to slide, thereby moving the steel plate 42. The bottom of the shell 1 is inserted between a pair of steel bars, so that the bottom of the shell 1 abuts against the template, and the pair of steel bars is positioned exactly between a pair of steel plates 42. There is a certain difference in the spacing between different pairs of steel bars. When the spacing between a pair of steel bars is slightly larger than that between a pair of steel plates 42, the bottom of the steel plate 42 will abut against the steel bars, thus pushing the steel plate 42 into the sliding frame 44. The third spring 43 is compressed, thus facilitating the adaptation to the spacing between a pair of steel bars and preventing the steel bars from moving to the sides, thereby playing a certain positioning role and preventing inconsistent spacing of the steel mesh during installation. When the bottom of the shell 1 abuts against the template, the thenar eminence of the palm is used to... Press down the actuating rod 21, and the actuating rod 21 slides into the interior of the housing 1. The inner inclined surface of the actuating rod 21 will abut against the contact wheel 25, pushing the contact wheel 25 to rotate. At the same time, the pushing rod 24 rotates into the middle of the interior of the housing 1. The bottom of the pushing rod 24 will push the insert plate 22 in the opposite direction to extend towards the steel plate 42. The first spring 23 will be compressed, and the insert plate 22 will be inserted into the bottom of the reinforcing bar, thereby lifting the reinforcing bar and achieving the limiting function. When the actuating rod 21 is pressed to the bottom, under the action of the second spring 33, the limiting block 32 enters into the limiting groove 35, thereby restricting the upward movement of the actuating rod 21, so that the insert plate 22 keeps the reinforcing bar in the state of lifting it. Pushing the push block 31 drives the control rod 36 to slide, driving the swing rod 37 to rotate. The swing rod 37 will pull the limiting block 32 away from the limiting groove 35 through the pulling rod 34, thereby facilitating the reset of the actuating rod 21.To maintain a certain distance between the reinforcing bars and the formwork, while holding the housing 1, repeatedly press the grip lever 51 upwards. The sixth spring 8 extends, and the grip lever 51 pulls the ratchet 55 to rotate via the first rack 54. The ratchet 55 rotates in one direction controlled by the pawl 57. When the grip lever 51 is released, the sixth spring 8 contracts, pulling the grip lever 51 downwards. The first rack 54 becomes serrated, thus pulling the ratchet 55 to rotate in one direction. As the grip lever 51 returns to its original position after downward movement, it moves a distance away from the ratchet 55, pushing the slider 7 to slide. This compresses the fifth spring 6. When the grip lever 51 reaches the bottom, the fifth spring 6 pushes the slider 7... The first rack 54 engages with the ratchet 55 again, thereby repeatedly pressing the grip 51 to rotate the ratchet 55, which in turn rotates the gear 58, driving the second rack 59 and the lifting block 52 to move downwards. The fourth spring 53 extends out from the bottom of the housing 1, supporting the housing 1 and lifting the reinforcing bar through the insert plate 22. This prevents the reinforcing bar from contacting the formwork surface during pouring, allowing the housing 1 to be disassembled while pouring. When disassembly of the housing 1 is required, the push block 31 is pushed, causing the swing rod 37 to rotate. The swing rod 37 pushes the pawl 57 and ratchet 55 apart through the contact rod 38, releasing the ratchet 55. The fourth spring 53 then pulls the lifting block 52 back to its original position.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
