Description

Technical Field

[0001] The present application relates to the technical field of wall construction, and in particular to a curved wall formwork and a construction process. Background Art

[0002] At present, the curved wall technology in my country is usually to enclose the casting area of ​​the curved structure through curved panels, and then pour concrete into the curved panels on site. When the concrete solidifies, the formwork is removed to realize the construction of the curved wall.

[0003] When constructing concrete, the concrete will exert outward pressure on the curved wooden board, which can easily cause the curved panel to deform. If the strength of the curved panel is not enough, it is very easy to cause the wall to deform, crack, and reduce strength due to deformation. Summary of the invention

[0004] In order to enhance the reinforcement of the curved panel, the present application provides a curved wall formwork and a construction process.

[0005] On the one hand, the application provides a curved wall formwork adopting the following technical solution:

[0006] A curved wall formwork comprises a curved panel and vertical purlins. There are multiple vertical purlins, which are fixed on one side of the curved panel in the vertical direction. A connecting seat is provided on the side of the vertical purlin facing away from the curved panel. A reinforcement structure for reinforcing the curved panel is provided between the connecting seat and the vertical purlin. The reinforcement structure comprises two relatively arranged reinforcing beams and two relatively arranged sliders. The two reinforcing beams correspond to the two sliders one by one. The two sliders move along the length direction of the connecting seat, and the movement is away from each other or close to each other. The two reinforcing beams are provided with slideways adapted for sliding of the sliders on the side facing the corresponding sliders. The two slideways are gradually inclined toward the connecting seat in a direction away from each other. An adjusting device for adjusting the movement of the slider is provided between the two sliders. A limiting component for limiting the movement of the reinforcing beam position is provided between the connecting seat and the reinforcing beam.

[0007] By adopting the above technical solution, when constructing the formwork, the vertical keel is first installed and fixed on the side of the curved panel away from the pouring to play a role of preliminary reinforcement, and then the bottom of the fixed beam is fixed to the ground, and the slider is driven by the adjustment device to move away from each other along the length direction of the connecting seat. The reinforcement beam cannot move under the restriction of the limiter, so the slider slides with the reinforcement beam on the slideway, causing the reinforcement beam to gradually tilt until the reinforcement beam abuts against the fixed beam. By the abutment of the reinforcement beam against the fixed beam, the curved panel is further reinforced, making the curved panel less likely to deform.

[0008] Optionally, the adjusting device includes a bidirectional lead screw and a connecting block. The circumferential side walls of the bidirectional lead screw have opposite spiral directions along the middle toward both ends. Two connecting blocks are provided. The two connecting blocks are respectively threadedly connected to the two thread sections of the bidirectional lead screw. The connecting block is connected to the slider. The connecting block is slidably connected to the connecting seat along the length direction of the connecting seat.

[0009] By adopting the above technical solution, the bidirectional lead screw is rotated, and the bidirectional lead screw is connected with the connecting block through a thread, so that the connecting blocks move away from each other, and the connecting block then drives the sliders to move away from each other.

[0010] Optionally, the limiting member is a limiting rod, which is located at one end of the reinforcement beams that are close to each other, one end of the limiting rod is fixedly connected to the connecting seat, and the other end of the limiting rod is hinged to the reinforcement beam.

[0011] By adopting the above technical solution, when the slider moves, the slider slides along the slideway and the reinforcement beam, causing the reinforcement beam to tilt. When the reinforcement beam tilts, the limit rod and the reinforcement beam rotate relative to each other, and the reinforcement beam cannot move, thereby limiting the reinforcement beam.

[0012] Optionally, a plurality of the curved panels are provided, the plurality of curved panels are abutted against each other, side ribs are fixedly provided at the edge lines of the curved panels along the vertical direction, the side ribs and the vertical purlins are located on the same side of the curved panels, a clamp for clamping the two is provided between adjacent side ribs, the clamp includes a movable clamp and a fixed clamp, and a movable device for adjusting the position of the movable clamp is provided between the movable clamp and the fixed clamp.

[0013] By adopting the above technical solution, the position of the movable clamp is adjusted by the movable device, and the adjacent side ribs are clamped by the movable clamp and the fixed clamp, so that the adjacent curved panels are clamped and fixed, and the reinforcement effect of the curved plate is further improved.

[0014] Optionally, the side rib has a slot along its length, and the movable clamp and the fixed clamp are both snap-fitted into the slot. The movable device includes a guide rod and a threaded rod. The guide rod is fixedly connected to the fixed clamp, the guide rod passes through the movable clamp and is slidably connected to the movable clamp, the threaded rod is rotatably connected to the fixed clamp, and the threaded rod passes through the movable clamp and is threadedly connected to the movable clamp.

[0015] By adopting the above technical solution, when the staff needs to move the mobile clamp, they only need to rotate the threaded rod, and through the threaded connection between the mobile clamp and the threaded rod, and under the guidance of the guide rod, the mobile clamp moves toward the fixed clamp.

[0016] Optionally, a connecting mechanism for connecting the two is provided between the clamp and the reinforcement beam, and the connecting mechanism includes a connecting rod and a rotating ring; one end of the connecting rod is hinged to the fixed clamp, and the other end of the connecting rod passes through the rotating ring and is slidingly connected to the rotating ring, the rotating ring is rotatably connected to the reinforcement beam, and the end of the connecting rod away from the fixed clamp is hinged to the connecting block.

[0017] By adopting the above technical solution, the connecting block drives the connecting rod to move when it moves, and at the same time the connecting rod drives the rotating ring to rotate and slide, and the connecting rod drives the clamp to move toward the side rib.

[0018] Optionally, multiple groups of reinforcement structures and multiple groups of adjustment devices are arranged along the length direction of the vertical keel, the reinforcement structures correspond to the adjustment devices one by one, and the arc panel is provided with a driving device on one side of the adjustment device for driving all the bidirectional screws to rotate simultaneously.

[0019] By adopting the above technical solution, the driving device can drive multiple sets of bidirectional screws to rotate simultaneously, so that multiple sets of reinforcement structures can strengthen the structure of the vertical keel, thereby further improving the reinforcement of the curved panel through the above structure.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] The embodiments of the present application disclose a curved wall formwork and a construction process.

[0039] refer to Figure 1 A curved wall formwork includes a curved panel 1, and a plurality of vertical keels 11 are fixedly arranged on the convex side of the curved panel 1 in the vertical direction. In the embodiment of the present application, four vertical keels 11 are arranged, and the four vertical keels 11 are symmetrically distributed along the middle of the curved panel 1. Concrete is poured into the concave side of the curved panel 1 for pouring, and the concrete exerts an outward pressure on the curved panel 1, and the curved panel 1 is reinforced through the vertical keels 11, so that the curved panel 1 is not easily deformed, thereby improving the quality of concrete pouring.

[0040] Reference Figure 1 and Figure 2 A connecting seat 2 is provided on the side of the vertical keel 11 away from the curved panel 1. The connecting seat 2 is provided in the horizontal direction. In the embodiment of the present application, three connecting seats 2 are provided, and the three connecting seats 2 are respectively located at the upper part, the middle part and the lower part of the curved panel 1. Fixed beams 21 are provided at both ends of the connecting seat 2, and the connecting seat 2 is fixedly connected to the fixed beams 21. A reinforcement structure 3 for further reinforcing the curved panel 1 is provided between the connecting seat 2 and the vertical keel 11. An adjustment device 4 for adjusting the reinforcement structure 3 is provided between the reinforcement structure 3 and the connecting seat 2. The bottom of the fixed beam 21 is fixed to the ground, and then the adjustment device 4 is adjusted so that the reinforcement structure 3 further reinforces the curved panel 1.

[0041] Reference Figure 3The reinforcement structure 3 includes two reinforcement beams 31 and two sliders 32. The two reinforcement beams 31 are symmetrically distributed along the center line of the connection seat 2. The two reinforcement beams 31 are provided with a slideway 311 on the side facing the connection seat 2. The two slideways 311 gradually tilt toward the connection seat 2 in the direction away from each other. The sliders 32 slide and fit the slideway 311, and the sliders 32 move away from each other along the length direction of the connection seat 2. In the embodiment of the present application, the sliders 32 are cylindrical. A limiter for limiting the position movement of the reinforcement beam 31 is provided between the reinforcement beam 31 and the connection seat 2. When the reinforcement structure 3 is needed to further reinforce the curved panel 1, the two sliders 32 are driven to move away from each other by the adjustment device 4. Due to the structure of the slideway 311 itself, the slider 32 rolls along the slideway 311, so that the two reinforcement beams 31 gradually move away from the connection seat 2 at one end away from each other until the reinforcement beam 31 abuts against the vertical keel 11, thereby achieving the effect of further reinforcing the curved panel 1.

[0042] The adjusting device 4 includes a bidirectional screw 41 and a connecting block 42. The circumferential side wall of the bidirectional screw 41 is processed with two sections of threads. The two sections of threads rotate in opposite directions along the middle of the bidirectional screw 41 to the two ends. Two connecting blocks 42 are provided. The two connecting blocks 42 are respectively located on the two sections of threads of the bidirectional screw 41 and are threadedly connected with the bidirectional screw 41. The connecting seat 2 is provided with a connecting path 22 along its own length direction toward the side of the connecting block 42. One side of the connecting seat 2 is rotatably connected to the slider 32, and the other side of the connecting block 42 extends into the connecting path 22 and is slidably connected to the connecting seat 2. When the staff needs to adjust the position of the slider 32, they only need to rotate the bidirectional screw 41 so that the bidirectional screw 41 drives the two connecting blocks 42 to move away from each other along the length direction of the connecting path 22, and the connecting block 42 can drive the slider 32 to move away from each other.

[0043] Reference Figure 2 and Figure 3 The limiting member is a limiting rod 5, which is located at one end of the reinforcement beam 31 close to each other. The limiting rod 5 is horizontally arranged and perpendicular to the connecting seat 2. One end of the limiting rod 5 is fixedly connected to the connecting seat 2, and the other end of the limiting rod 5 is rotatably connected to the side wall of the reinforcement beam 31. When the reinforcement beam 31 rotates, the limiting rod 5 can limit the reinforcement beam 31, so that the slider 32 cannot drive the reinforcement beam 31 to move together.

[0044] Reference Figure 1 and Figure 4 A side rib 12 is fixed on one side of the convex surface of the curved panel 1. Two side ribs 12 are provided for each curved panel 1. The two side ribs 12 are arranged along the vertical direction and are located on both sides of the curved panel 1. A clamp 6 for reinforcing adjacent curved panels 1 and a connecting mechanism 8 for connecting the clamp 6 and the connecting block 42 are provided between the reinforcement structure 3 and the side rib 12. The reinforcement structures 3 corresponding to different curved panels 1 are staggered.

[0045] Adjacent side ribs 12 are provided with a slot 121 along their length direction on the side facing away from each other. The clamp 6 includes a movable clamp 61 and a fixed clamp 62, and the movable clamp 61 and the fixed clamp 62 are relatively arranged on both sides of the side rib 12. A movable device 7 for driving the movable clamp 61 to move is arranged between the movable clamp 61 and the fixed clamp 62. The movable device 7 includes a guide rod 71 and a threaded rod 72, and two guide rods 71 ​​are arranged. The two guide rods 71 ​​are respectively fixed on both sides of the fixed clamp 62, and the guide rod 71 passes through the movable clamp 61 and is slidably connected to the movable clamp 61. The threaded rod 72 is located between the two guide rods 71 ​​and is rotatably connected to the fixed clamp 62. The threaded rod 72 passes through the movable clamp 61 and is threadedly connected to the movable clamp 61. The threaded rod 72 is fixedly connected to a hand wheel 721 at one end of the threaded rod 72 away from the fixed clamp 62.

[0046] Reference Figure 4 The connection mechanism 8 includes a connection rod 81 and a rotating ring 82. The rotating ring 82 is rotatably connected to the connection seat 2. One end of the connection rod 81 is rotatably connected to the connection block 42. The connection rod 81 passes through the inside of the rotating ring 82 and is slidably connected to the rotating ring 82. The other end of the connection rod 81 is hinged to the fixed clamp 62. When the connection blocks 42 move away from each other, the connection block 42 drives the connection rod 81 to move, the connection rod 81 drives the rotating ring 82 to rotate, and the connection rod 81 drives the fixed clamp 62 to move toward the side rib 12. When the fixed clamp 62 moves to the side rib 12, the staff rotates the hand wheel 721 to move the mobile clamp 61 toward the fixed clamp 62, and the side rib 12 is clamped between the mobile clamp 61 and the fixed clamp 62, thereby achieving the reinforcement of the adjacent curved panels 1.

[0047] Reference Figure 4 and Figure 5A driving device for driving a plurality of bidirectional lead screws 41 to rotate simultaneously is provided on one side of the convex surface of the arc panel 1. The driving device comprises a driving motor 91, a driving shaft 92, a driving bevel gear 93, a connecting bevel gear 94, a driving gear 95, a driving chain 96 and a driven gear 97; the body of the driving motor 91 is fixedly connected to the upper surface of the uppermost connecting seat 2, the end of the output shaft of the driving motor 91 is fixedly connected to the driving bevel gear 93, the driving shaft 92 is rotationally connected to the connecting seat 2, one end of the driving shaft 92 is fixedly connected to the connecting bevel gear 94, the other end of the driving shaft 92 is fixedly connected to the driving gear 95, and a plurality of driven gears 97 are provided, and the plurality of driven gears 97 correspond to the plurality of bidirectional lead screws 41 one by one, the bidirectional lead screw 41 passes through the driven gear 97, and the driven gear 97 is fixedly connected to the middle of the bidirectional lead screw 41. The driving chain 96 is meshed around the driving gear 95 and the driven gear 97. When the bidirectional lead screw 41 needs to be rotated, the drive motor 91 can be started, the drive motor 91 drives the drive bevel gear 93 to rotate, the drive bevel gear 93 rotates the drive shaft 92 by meshing with the connecting bevel gear 94, the drive shaft 92 drives the drive gear 95 to rotate, the drive gear 95 drives the driven gear 97 to rotate through the drive chain 96, and the driven gear 97 drives the bidirectional lead screw 41 to rotate. The above structure achieves the effect of the bidirectional lead screw 41 rotating simultaneously.

[0049] S2, start the driving motor 91 to make the multiple bidirectional screws 41 rotate simultaneously, and the bidirectional screws 41 drive the connecting blocks 42 to move away from each other, so that the reinforcement beam 31 gradually tilts and abuts against the vertical keel 11, thereby achieving the effect of further reinforcing the curved panel 1;
