Description

A type of road culvert construction formwork Technical Field

[0001] This application relates to the technical field of road culvert structures, and in particular to a road culvert construction formwork. Background Technology

[0002] A culvert is a water passage built under the roadbed and below the road surface in highway construction to allow water to flow under the highway without obstructing traffic.

[0003] The existing road culvert structure includes a steel frame and a concrete layer. The concrete layer wraps around the steel frame to form an arch structure. The steel frame includes several longitudinal bars, several transverse bars and several arch bars. The longitudinal bars are arranged vertically in two rows at intervals. The two ends of the arch bars are respectively connected to two longitudinal bars to form an arch structure. The transverse bars are vertically connected to the arch bars or several longitudinal bars at intervals around the perimeter.

[0004] Regarding the aforementioned technologies, when connecting longitudinal bars, transverse bars, and arch bars, existing technologies generally employ point-by-point welding of the contact surfaces. This method requires manual support while welding, which is cumbersome and inefficient. Summary of the Invention

[0005] To address the issue of low construction efficiency in existing technologies, this application provides a road culvert construction formwork.

[0006] The following technical solution is adopted:

[0007] A road culvert construction formwork includes several longitudinal connecting rods, several transverse ribs, and several arch ribs. The longitudinal connecting rods are arranged vertically in two rows at intervals. Each arch rib is connected to two longitudinal connecting rods at its two ends to form an arch structure. The transverse ribs are vertically connected to the arch ribs or the longitudinal connecting rods at intervals around their periphery. Each arch rib has a connecting sleeve at both ends. Each longitudinal connecting rod includes a connector and several support sleeves. The connector passes through the connecting sleeve. A first limiting component is provided inside the longitudinal connecting rod to prevent the connecting sleeve from detaching from the connector. The support sleeves are arranged in an array on the longitudinal connecting rod. The transverse ribs pass through the corresponding support sleeves. A second limiting component is provided inside the longitudinal connecting rod to prevent the transverse ribs from detaching from the support sleeves. A linkage component is provided inside the longitudinal connecting rod to simultaneously drive the first limiting component and the second limiting component. A hanging sleeve for passing through the transverse ribs is provided on the arch rib.

[0008] By adopting the above technical solution, the longitudinal connecting rod is connected to the arch reinforcement by the connector and limited by the first limiting component, and connected to the transverse reinforcement by the support sleeve and fixed by the second limiting component. The first limiting component and the second limiting component are controlled simultaneously only by the linkage component, thereby providing a formwork structure that is easy to connect and fix, increasing the formwork erection efficiency, and thus making the overall construction process of the road culvert faster.

[0009] Optionally, the longitudinal connecting rod has a control groove along its axis, and the linkage is a rod-shaped structure passing through the control groove, and the linkage is rotatably connected to the longitudinal connecting rod.

[0010] By adopting the above technical solution, the linkage can be controlled by rotation, which facilitates the operation of the first limit component and the second limit component.

[0011] Optionally, the first limiting component includes several locking blocks and a first sleeve. One end of the locking block is rotatably connected to one end of the connector. The control groove passes through the connector. The first sleeve is slidably connected in the control groove. After the first sleeve can slide, it pushes the locking block to rotate outward from the outer wall of the longitudinal connecting rod. The first sleeve is sleeved and threadedly connected to one end of the linkage. A first protrusion is provided on the periphery of the first sleeve. A first groove for the first protrusion to slide is opened on the inner wall of the control groove along the length direction of the first sleeve.

[0012] By adopting the above technical solution, the rotation of the linkage causes the first sleeve to move and abut against the locking block, which in turn squeezes the connecting sleeve, increasing the connection stability of the connecting sleeve.

[0013] Optionally, each of the card blocks is provided with a first magnet that attracts each other on the side where they are close to each other.

[0014] By adopting the above technical solution, the two blocks are attracted to each other by the first magnet and stored in the extension surface of the outer wall of the longitudinal connecting rod, making the connecting sleeve easier to insert.

[0015] Optionally, the second limiting component includes a rotating sleeve and a limiting sleeve. The supporting sleeve has a rotating groove coaxially provided for the rotating sleeve to rotate. The limiting sleeve is slidably connected to the rotating sleeve coaxially. One end of the limiting sleeve is threadedly connected to the rotating sleeve, and the other end is provided with a second protrusion circumferentially. The inner wall of the supporting sleeve has a second groove for the second protrusion to slide. The transverse rib passes through the limiting sleeve. The inner wall of the rotating sleeve at the end away from the limiting sleeve is inclined inward to form a chamfer. The end of the limiting sleeve near the chamfer is deformable.

[0016] By adopting the above technical solution, the rotating sleeve rotates and drives the limiting sleeve connected to it to move, so that one end of the limiting sleeve deforms due to the chamfer and tightens the horizontal rib, thereby increasing the stability of the horizontal rib connection.

[0017] Optionally, the linkage component is provided with a first volute at a position corresponding to one of the rotating sleeves, and a second volute engaging with the first volute is provided on the outer periphery of the rotating sleeve. A clearance groove is provided inside the support sleeve for the second volute to rotate, and the clearance groove communicates with the control groove.

[0018] By adopting the above technical solution, the first and second worm gears cooperate to enable the rotating sleeve to rotate when the linkage rotates.

[0019] Optionally, the longitudinal connecting rod has a plurality of through slots arranged in a circumferential array at one end away from the connector, and a slidable thorn is provided in the through slot. A third limiting component is provided inside the longitudinal connecting rod, which can drive the thorn to move and extend beyond the outer wall extension surface of the longitudinal connecting rod.

[0020] By adopting the above technical solution, the spikes can be pushed out and inserted into the soil, increasing the connection between the longitudinal connecting rod and the soil.

[0021] Optionally, the third limiting component includes a second sleeve, which is slidably connected to the control groove. After the second sleeve can slide, it pushes the thorn to extend outward toward the outer wall extension surface of the longitudinal connecting rod. The second sleeve is sleeved and threadedly connected to one end of the linkage. A third protrusion is provided on the periphery of the second sleeve. A third groove is provided on the inner wall of the control groove along the length direction of the second sleeve for the third protrusion to slide.

[0022] By adopting the above technical solution, the movement of the second sleeve drives the movement of the thorn, thereby providing a solution for driving the thorn to extend out of the through groove.

[0023] Optionally, each of the proximal ends of the thorns is provided with a second magnet that attracts each other.

[0024] By adopting the above technical solution, the effect is the same as that of the first magnet.

[0025] Optionally, one end of some of the transverse ribs is provided with an end block, and the other end is detachably connected with an end ring.

[0026] In summary, this application includes at least one of the following beneficial effects:

[0027] 1. A formwork structure that is easy to connect and fix is ​​provided, which increases the efficiency of formwork erection and thus makes the overall construction process of road culverts faster;

[0028] 2. The first limit component, the second limit component, and the third limit component can be controlled simultaneously through the linkage to facilitate installation. Attached Figure Description

[0037] The present application will be further described in detail below with reference to Figures 1 to 7.

[0038] Referring to Figures 1 and 2, this application discloses a road culvert construction formwork, including several longitudinal connecting rods 1, several transverse reinforcing bars 2, and several arch reinforcing bars 3. All the longitudinal connecting rods 1, transverse reinforcing bars 2, and arch reinforcing bars 3 are made of metal. The longitudinal reinforcing bars are arranged vertically in two rows at intervals. The arch reinforcing bars 3 are arc-shaped, with each end of an arch reinforcing bar 3 connected to two longitudinal reinforcing bars to form an arch structure. The transverse reinforcing bars 2 are vertically connected to the arch reinforcing bars 3 or the longitudinal reinforcing bars at intervals along their periphery, thus forming a mesh structure.

[0039] Referring to Figures 2 to 4, further, each end of the arch reinforcement 3 is provided with a connecting sleeve 31, and the longitudinal connecting rod 1 includes a connecting head 11 and several supporting sleeves 12. The connecting head 11 passes through the connecting sleeve 31, and a first limiting component 4 is provided inside the longitudinal connecting rod 1 to prevent the connecting sleeve 31 from detaching from the connecting head 11. After the connecting head 11 passes through the connecting sleeve 31, the first limiting component 4 limits the connecting sleeve 31, thereby fixing the arch reinforcement 3 and the longitudinal connecting rod 1. Several supporting sleeves 12 are arrayed on the longitudinal connecting rod 1, and the supporting sleeves 12 are arranged along the length direction of the culvert. The supporting sleeves 12 of the two longitudinal connecting rods 1 located in the plane perpendicular to the length direction of the culvert are located on opposite sides. The transverse reinforcement 2 passes through the corresponding supporting sleeve 12, and a second limiting component 5 is provided inside the longitudinal connecting rod 1 to prevent the transverse reinforcement 2 from detaching from the supporting sleeve 12. A linkage 6 is provided inside the longitudinal connecting rod 1 for simultaneously driving the first limiting component 4 and the second limiting component 5. The arch reinforcement 3 is provided with a hanging sleeve 32 for threading the transverse reinforcement 2. Several transverse reinforcements 2 have an end block 21 at one end and an end ring detachably connected to the other end. The diameter of the end block 21 and the end ring is larger than the inner diameter of the hanging sleeve 32. After the transverse reinforcement 2 is threaded through several hanging sleeves 32 that are in the same straight line, the two ends can be fixed by the end block 21 and the end ring to prevent the transverse reinforcement 2 from falling off the hanging sleeve 32.

[0040] Referring to Figures 2 to 4, specifically, the longitudinal connecting rod 1 has a control groove 13 along its axis, and the linkage 6 is a rod-shaped structure passing through the control groove 13. The linkage 6 is rotatably connected to the longitudinal connecting rod 1. This allows the linkage 6 to be controlled by rotation, facilitating the operation of the first limiting component 4 and the second limiting component 5. Furthermore, a reinforcing block 14 is provided at the middle of the longitudinal connecting rod 1, with a through-hole 141 formed on both sides of the reinforcing block 14. The through-hole 141 communicates with the control groove 13, and the linkage 6 is provided with a lever 61, which can pass through the through-hole 141 to the outside. Rotating the lever 61 can drive the linkage 6 to rotate, thereby controlling the first limiting component 4 and the second limiting component 5.

[0041] Referring to Figures 2 to 4, specifically, the first limiting component 4 includes at least two locking blocks 41 and a first sleeve 42. The bottom of the two locking blocks 41 on the side furthest from each other is rotatably connected to one end of the connector 11. Each locking block 41 on the side closest to each other is provided with a first magnet 411 that attracts each other; the first magnet 411 is a magnetic sheet attached to one side of the locking block 41. In the initial state, the two locking blocks 41 attract each other through the first magnet 411, thereby allowing the locking blocks 41 to be housed within the outer wall extension surface of the longitudinal connecting rod 1. This makes the insertion of the connecting sleeve 31 smoother. The control groove 13 extends upward through the connector 11 and communicates with the outside world, and the first sleeve 42 is slidably connected within the control groove 13. The end of the first sleeve 42 furthest from the linkage 6 is a pointed tip; after the first sleeve 42 can slide, the pointed tip pushes the locking block 41 to rotate outward from the outer wall extension surface of the longitudinal connecting rod 1. The first sleeve 42 is fitted and threaded to one end of the linkage 6. A first protrusion 421 is provided on the periphery of the first sleeve 42. A first groove 131 for sliding the first protrusion 421 is opened on the inner wall of the control groove 13 along the length of the first sleeve 42. The first sleeve 42 and the linkage 6 are connected by threads. When the linkage rotates, the first sleeve 42 is driven to move. Due to the cooperation of the first protrusion 421 and the first groove 131, the rotation of the first sleeve 42 is restricted. Thus, the first sleeve 42 moves along the length of the longitudinal connecting rod 1, thereby passing through the control groove 13 and pushing the locking block 41 to rotate. However, after the connecting sleeve 31 is fitted into the connecting head 11, the locking block 41 locks the connecting sleeve 31 onto the connecting head 11 from the inside out, thereby making the connection between the arch rib 3 and the longitudinal connecting rod 1 more stable.

[0042] Referring to Figures 2 to 6, specifically, the second limiting component 5 includes a rotating sleeve 51 and a limiting sleeve 52. The support sleeve 12 has a rotating groove 121 coaxially formed for the rotating sleeve 51 to rotate, and the side of the rotating groove 121 communicates with the control groove 13. The limiting sleeve 52 is coaxially slidably connected inside the rotating sleeve 51. One end of the limiting sleeve is threaded to the inner wall of the rotating sleeve 51, and the other end has a second protrusion 521 circumferentially provided. The inner wall of the support sleeve 12 has a second groove 1211 for the second protrusion 521 to slide. The transverse rib 2 passes through the limiting sleeve 52, and the inner wall of the rotating sleeve 51 at the end away from the limiting sleeve 52 is inclined inward to form a chamfer 511. The end of the limiting sleeve 52 near the chamfer 511 has several deformation grooves circumferentially formed. When this end of the limiting sleeve 52 moves, it abuts against the chamfer 511. As the limiting sleeve 52 continues to move, it can deform, thereby tightening the transverse rib 2. This restricts the horizontal rib 2 from detaching from the support sleeve 12.

[0043] Referring to Figures 2 to 5, the linkage 6 and several rotating sleeves 51 are provided with first volutes 62 at corresponding positions, and the outer periphery of the rotating sleeves 51 is provided with second volutes 512 that mesh with the first volutes 62. A clearance groove 1212 for the second volutes 512 to rotate is provided inside the support sleeve 12, and the clearance groove 1212 communicates with the control groove 13. This provides a method to enable the linkage 6 to drive the rotating sleeves 51 to rotate when it rotates.

[0044] Referring to Figures 2 to 7, specifically, the longitudinal connecting rod 1 has several through slots 15 arranged in a circumferential array at the end away from the connector 11. A spike 151 is slidably connected in each through slot 15. A third limiting component 7 is provided inside the longitudinal connecting rod 1, capable of driving the spike 151 to extend beyond the outer wall of the longitudinal connecting rod 1. Under the action of the third limiting component 7, the spike 151 extends and inserts into the soil, making the connection between the longitudinal connecting rod 1 and the soil more stable.

[0045] Referring to Figures 2 to 7, the third limiting component 7 further includes a second sleeve 71, which is slidably connected within the control groove 13. The end of the second sleeve 71 furthest from the linkage member 6 is a pointed tip, allowing the second sleeve 71 to slide and push the thorn 151 outwards from the outer wall of the longitudinal connecting rod 1. The second sleeve 71 is fitted and threadedly connected to one end of the linkage member 6, with the thread being opposite to that of the first sleeve 42. A third protrusion 721 is provided around the second sleeve 71, and a third groove 132 for sliding the third protrusion 721 is formed along the length of the second sleeve 71 on the inner wall of the control groove 13. The second sleeve 71 and the linkage 6 are connected by threads. When the linkage rotates, the second sleeve 71 is driven to move away from the linkage 6. Due to the cooperation of the third protrusion 721 and the third groove 132, the rotation of the second sleeve 71 is restricted. As a result, the second sleeve 71 moves along the length of the longitudinal connecting rod 1, thereby squeezing the thorn 151 out of the through groove 15 in sequence, so that the thorn 151 is inserted into the soil, increasing the connection between the longitudinal connecting rod 1 and the soil, making the longitudinal connecting rod 1 more stable.

[0046] Referring to Figures 2 to 5, further, each of the several spikes 151 is provided with a second magnet 152 that attracts each other at one end. The second magnet 152 is a magnetic block provided at one end of the spike 151. The effect of the second magnet 152 is the same as that of the first magnet 411, so that the spike 151 is initially housed in the extension surface of the outer wall of the longitudinal connecting rod 1.

[0047] The implementation principle of a road culvert construction formwork according to an embodiment of this application is as follows:

[0048] After excavating the construction site, measure and vertically excavate several suitable rows of holes at intervals on the soil surface. Insert the longitudinal connecting rods 1 into the holes one by one, and arrange the support sleeves 12 on the longitudinal connecting rods 1 on the same side in a straight line. Pass the transverse reinforcing bars 2 through the support sleeves 12 one by one to provide transverse support for the longitudinal connecting rods 1. Insert the connecting sleeves 31 at both ends of the arch reinforcing bar 3 into the corresponding connecting heads 11 from top to bottom to install the arch reinforcing bar 3. By rotating the linkage 6, the first sleeve in the first limiting component 4 is driven to move and push out the locking block 41, thereby restricting the arch reinforcing bar 3; at the same time, through the cooperation of the first volute 62 and the second volute 512, the rotating cylinder is driven to rotate, thereby causing the limiting sleeve 52 to deform and squeeze the transverse reinforcing bar 2 to restrict the transverse reinforcing bar 2. Pass the remaining transverse reinforcing bars 2 into the hanging sleeves 32 of the arch reinforcing bar 3. Simultaneously, the linkage 6 drives the third limiting component, which in turn drives the second sleeve 71, causing the second sleeve 71 to expel several spikes 151 through the through hole and insert them into the soil, making the connection between the longitudinal connecting rod 1 and the soil more stable. This forms a steel structure formwork, which can then be poured with wooden planks on the outside to form a road culvert.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
