Technical Field

[0001] The utility model relates to the technical field of laminated plates, and specifically relates to a formwork reinforcement device for the post-cast strip of laminated plates. Background Technique

[0002] The post-cast strip is a concrete strip left at the corresponding positions of the foundation slab, wall, and beam according to design or construction specification requirements to prevent harmful cracks that may occur in the reinforced concrete structure due to uneven self-shrinkage or settlement. However, we found in actual life that when pouring the post-cast strip, it is necessary to install a mold at the bottom before pouring. However, when pouring concrete, due to the fluidity of the concrete, the flowing concrete will squeeze the formwork, resulting in deformation of the formwork. Therefore, it is necessary to clean the protruding concrete before pouring the post-cast strip, which brings a large workload to the staff. For this reason, we propose a formwork reinforcement device for the post-cast strip of laminated plates. Content of the Utility Model

[0025] Push plates 2, there are two of them, and the two push plates 2 are respectively arranged on the inner wall of the template body 1;

[0026] Extrusion assembly 3, arranged in the template body 1, and the two push plates 2 are controlled by the extrusion assembly 3 to extrude the inner wall of the template body 1.

[0027] The extrusion assembly 3 includes a driving member 4 arranged in the template body 1, which provides power for the two push plates 2 by using the driving member 4. A lifting member 5 is arranged in the template body 1 to control the extrusion force of the two push plates 2 by using the lifting member 5. An auxiliary member 6 is arranged in the template body 1 to assist the two push plates 2 to extrude the inner wall of the template body 1 by using the auxiliary member 6. A transmission member 7 is arranged in the template body 1 to transmit power for the two push plates 2 by using the transmission member 7.

[0028] The driving member 4 includes a driving handle 41 arranged in the template body 1. A driving ring 42 is arranged on the outer side of the driving handle 41. A driving plate 43 is rotatably arranged on the outer side of the driving handle 41, and the driving plate 43 is located below the driving ring 42. By rotating the driving handle 41, the driving handle 41 will drive the driving ring 42 on its outer side to rotate together when rotating, and the driving plate 43 rotatably arranged on the outer side of the driving handle 41 will be blocked below the driving ring 42 by the driving ring 42. Its function is to control the driving plate 43 to move downward by the driving handle 41 to provide power for the two push plates 2 to extrude the inner wall of the template.

[0029] The lifting member 5 includes a fixing rod 51 disposed within the template body 1. A threaded groove 52 is formed within the fixing rod 51. A screw rod 53 is provided at the bottom of the driving handle 41, and the screw rod 53 is threadedly connected to the threaded groove 52 of the fixing rod 51 through the threaded groove 52. When the driving handle 41 rotates, the driving handle 41 will drive the screw rod 53 at its bottom to rotate, so that the screw rod 53 slowly moves downward through the threaded groove 52 within the fixing rod 51, and further causes the driving plate 43 outside the driving handle 41 to move downward together. Its function is to enable the driving plate 43 to move downward through the cooperation of the screw rod 53 and the threaded groove 52.

[0030] The auxiliary member 6 includes auxiliary rods 61 respectively disposed on both sides of the driving plate 43. First auxiliary rings 62 are rotatably provided on the outer sides of the two auxiliary rods 61. Second auxiliary rings 63 are rotatably provided on the outer sides of the auxiliary rods 61, and the two second auxiliary rings 63 are respectively located at the opposite ends of the two first auxiliary rings 62. When the driving plate 43 moves downward, the driving plate 43 will drive the auxiliary rods 61 on both sides to move downward together. When the auxiliary rods 61 move downward, the first auxiliary rings 62 and the second auxiliary rings 63 on the outer sides of the auxiliary rods 61 will move downward together with the auxiliary rods 61. Its function is to be able to control the first auxiliary ring 62 and the second auxiliary ring 63 to move downward together under the action of the driving plate 43, so that the first auxiliary ring 62 and the second auxiliary ring 63 drive the corresponding first transmission plate 71 and the second transmission plate 72 to start moving.

[0031] The transmission member 7 includes first transmission plates 71 respectively arranged on one side of two first auxiliary rings 62, and both of the two first transmission plates 71 are rotatably connected to the adjacent push plates 2 through rotating shafts. Second transmission plates 72 are arranged on one side of two second auxiliary rings 63 away from the two first transmission plates 71, and both of the two second transmission plates 72 are rotatably connected to the adjacent push plates 2 through rotating shafts. When the first auxiliary ring 62 moves downward under the action of the auxiliary rod 61, the first transmission plate 71 arranged on the outer side of the first auxiliary ring 62 will rotate on the outer side of the auxiliary rod 61 through the first auxiliary ring 62. Since one end of the first transmission plate 71 away from the first auxiliary ring 62 is rotatably connected to the corresponding push plate 2 through a rotating shaft, one end of the first transmission plate 71 away from the first auxiliary ring 62 squeezes the corresponding push plate 2, so that the push plate 2 rotatably connected to the first transmission plate 71 through a rotating shaft squeezes the inner wall of the template body 1. When the second auxiliary ring 63 moves downward under the action of the auxiliary rod 61, the second transmission plate 72 arranged on the outer side of the second auxiliary ring 63 will rotate on the outer side of the auxiliary rod 61 through the second auxiliary ring 63. Since one end of the second transmission plate 72 away from the second auxiliary ring 63 is rotatably connected to the corresponding push plate 2 through a rotating shaft, one end of the second transmission plate 72 away from the second auxiliary ring 63 squeezes the corresponding push plate 2, so that the push plate 2 rotatably connected to the second transmission plate 72 through a rotating shaft squeezes the inner wall of the template body 1. Its function is to convert the downward force of the driving plate 43 into a thrust force to both sides, so that the two push plates 2 squeeze the inner wall of the template.

[0032] During use, when the user needs to reinforce the template body 1, by rotating the driving handle 41, the driving ring 42 outside the driving handle 41 will rotate together when the driving handle 41 rotates, and the driving plate 43 arranged outside the driving handle 41 will be blocked below the driving ring 42 by the driving ring 42. When the driving handle 41 rotates, the driving handle 41 will drive the screw rod 53 at its bottom to rotate, so that the screw rod 53 slowly moves downward through the thread groove 52 in the fixing rod 51, and then the driving plate 43 outside the driving handle 41 moves downward together. When the driving plate 43 moves downward, the auxiliary rods 61 on both sides of the driving plate 43 will move downward together. When the auxiliary rods 61 move downward, the first auxiliary ring 62 and the second auxiliary ring 63 outside the auxiliary rods 61 will move downward together with the auxiliary rods 61. When the first auxiliary ring 62 moves downward under the action of the auxiliary rod 61, the first transmission plate 71 arranged outside the first auxiliary ring 62 will rotate on the outside of the auxiliary rod 61 through the first auxiliary ring 62. Since one end of the first transmission plate 71 far from the first auxiliary ring 62 is rotatably connected to the corresponding push plate 2 through a rotating shaft, one end of the first transmission plate 71 far from the first auxiliary ring 62 squeezes the corresponding push plate 2, so that the push plate 2 rotatably connected to the first transmission plate 71 through a rotating shaft squeezes the inner wall of the template body 1 nickel. When the second auxiliary ring 63 moves downward under the action of the auxiliary rod 61, the second transmission plate 72 arranged outside the second auxiliary ring 63 will rotate on the outside of the auxiliary rod 61 through the second auxiliary ring 63. Since one end of the second transmission plate 72 far from the second auxiliary ring 63 is rotatably connected to the corresponding push plate 2 through a rotating shaft, one end of the second transmission plate 72 far from the second auxiliary ring 63 squeezes the corresponding push plate 2, so that the push plate 2 rotatably connected to the second transmission plate 72 through a rotating shaft squeezes the inner wall of the template body 1.

[0033] Embodiment 2

[0034] Please refer to Figure 6 、 Figure 7 The present utility model provides a technical solution:

[0035] Different from Embodiment 1, a control groove 8 is formed at the top of the driving handle 41, and the control groove 8 is polygonal. A control rod 9 that is matched with the control groove 8 is movably arranged in the control groove 8. A control handle 10 is arranged at the top of the control rod 9. When there is a large amount of steel bars above the post-cast strip, the hands of the staff cannot reach into the template body 1 and cannot rotate the driving handle 41. By inserting the control rod 9 into the control groove 8 at the top of the driving handle 41 and then rotating the control handle 10, the driving handle 41 rotates through the control rod 9 and the control groove 8. Its function is to be able to control the rotation of the driving handle 41 by using the control handle 10 when there is an obstacle above the template body 1.
