Description

Technical Field

[0001] The utility model relates to the technical field of supporting devices, in particular to a supporting device for precast components. Background Technique

[0002] The beam-column joints of reinforced concrete frame structures, also known as the core areas of joints, are important components of the main structure. Most of the seismic damages of frame structures occur in columns and the core areas of beam-column joints. The failure of joints is mainly shear failure and steel bar anchorage failure, which may cause the collapse of the entire frame in severe cases. In engineering practice, insufficient attention is often paid to the construction of joints, and the construction quality control of joints is not strict.

[0003] The Chinese utility model patent with the patent publication number CN218699996U, which was publicly disclosed on March 24, 2023, discloses a supporting device for concrete precast components. A support plate, a support rod, a lifting adjustment rod and a driving mechanism are arranged below the fixing plate. A support plate is arranged on the support plate, and one end of the support plate and the support rod are hinged. The fixing plate and the support rod are rotationally connected. The axis of rotation of the support rod with the support plate and the fixing plate is perpendicular. Thus, by controlling the up and down swing of the support rod and controlling the rotation of the fixing plate relative to the support rod, the levelness of the fixing plate can be easily adjusted, and the quality of the concrete precast component after forming can be improved. However, it can only provide rigid support for the precast component, and may cause damage to the precast component during support. Summary of the Utility Model

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0020] As Figures 1-4As shown in the figure, the support device for prefabricated components in this embodiment includes a top plate 1, a central spring 2, a bottom plate 3, and a reinforcement assembly 4. The top of the top plate 1 abuts against the prefabricated component, the bottom of the top plate 1 is fixed to the central spring 2, the bottom of the central spring 2 is fixed to the top of the bottom plate 3, the reinforcement assembly 4 is arranged on the outer periphery of the central spring 2, the top of the reinforcement assembly 4 is fixed to the bottom of the top plate 1, and the bottom of the reinforcement assembly 4 is fixed to the top of the bottom plate 3. The reinforcement assembly 4 includes a plurality of first connecting rods 41, a plurality of second connecting rods 42, and a plurality of auxiliary springs 43. The top of the first connecting rod 41 is connected to the bottom of the top plate 1 by a first ball 411 in a rolling manner, the bottom of the first connecting rod 41 is hinged to the top of the second connecting rod 42, and the bottom of the second connecting rod 42 is connected to the top of the bottom plate 3 by a second ball 421 in a rolling manner; both ends of the auxiliary spring 43 are fixed to the hinge points of a group of the first connecting rod 41 and the second connecting rod 42 respectively.

[0021] When supporting the prefabricated component, the top plate 1 is stressed downward. Under the action of the top plate 1, the central spring 2 is stressed and contracts, and at the same time drives the first connecting rod 41 and the second connecting rod 42 to bend outward; the reinforcement assembly 4 is arranged on the outer periphery of the central spring 2, which can prevent the central spring 2 from tilting around when it is stressed and bent.

[0022] Furthermore, a first connecting plate 412 is fixed to the bottom of the first connecting rod 41, a second connecting plate 422 is fixed to the top of the second connecting rod 42, the side wall of the first connecting plate 412 abuts against the side wall of the second connecting plate 422, a rotating shaft penetrates through the middle parts of the first connecting plate 412 and the second connecting plate 422, and both ends of the rotating shaft are respectively connected to a rotating plate 44 in a rotating manner. A first ring 45 is fixed to the outer wall of the rotating plate 44; both ends of the auxiliary spring 43 are respectively fixed to a mounting plate 431, a second ring 432 is fixed to the outer side wall of the mounting plate 431, and the first ring 45 is sleeved with the second ring 432.

[0023] The bottom of the first connecting plate 412 and the top of the second connecting plate 422 are of an arc structure. When the connecting plate contacts the connecting rod, the arc structure can prevent jamming between the connecting plate and the connecting rod; both ends of the rotating shaft are connected to the second ring 432 of the auxiliary spring 43 through the rotating plate 44 and the first ring 45 to ensure that the auxiliary spring 43 does not rotate when the first connecting rod 41 and the second connecting rod 42 rotate.

[0024] Furthermore, a rubber pad is fixed to the top of the top plate 1.

[0025] The rubber pad further provides protection for the prefabricated component to prevent the prefabricated component from being damaged.

[0026] Furthermore, the central spring 2 is a large-diameter metal compression spring.

[0027] The large-diameter metal compression spring requires a relatively large resistance to generate deformation to ensure that the overall device will not change randomly.

[0028] The usage method of the present utility model is as follows:

[0029] When supporting the precast component, the top plate 1 is stressed downward. Under the action of the top plate 1, the central spring 2 is stressed and contracts, and at the same time drives the first connecting rod 41 and the second connecting rod 42 to bend outward; the reinforcement assembly 4 is arranged on the outer periphery of the central spring 2, which can prevent the central spring 2 from tilting around when it is stressed and bent; the bottom of the first connecting plate 412 and the top of the second connecting plate 422 are arc-shaped structures. When the connecting plate contacts the connecting rod, the arc-shaped structure can prevent jamming between the connecting plate and the connecting rod; both ends of the rotating shaft are connected to the second ring 432 of the auxiliary spring 43 through the rotating plate 44 and the first ring 45 to ensure that the auxiliary spring 43 does not rotate when the first connecting rod 41 and the second connecting rod 42 rotate.
