Example two
The inventor finds in practice that more and more bridge buildings adopt a prestressed concrete beam body block structure, and are spliced into a large-span continuous beam through a wet joint, because the block structure of the prestressed concrete beam body bears a certain pressure in advance before the load action, the tensile capacity of the concrete when bearing the load can be improved, namely, the deficiency of the tensile strength of the concrete is made up by the higher compressive strength of the concrete, the occurrence of concrete cracks is prevented or delayed, the rigidity of the structure is increased, steel and cement are saved, the pre-stress is usually achieved by stretching the reinforcing steel bars, so that the prestressed concrete beam block structure has a certain curvature when in use, and the connecting assembly of the bridge wet joint construction formwork provided in the first embodiment cannot clamp the construction formwork according to the bending radian of the prestressed concrete beam body partition structure when in use. In view of the above problems, the second embodiment of the present invention improves the first embodiment, the technical solution of the second embodiment includes all the technical solutions of the first embodiment, and the implementation of the second embodiment does not affect the single implementation of the first embodiment.
Referring to fig. 1 to 5, in the second embodiment, the construction formwork is a flexible plate, and the upper part of the extrusion plate 17 is composed of flexible magnets 30, and the lower part of the extrusion plate 17 is composed of electromagnets 31. Specifically, when the connecting assembly of the bridge wet joint construction formwork provided by the second embodiment is used, the two construction formworks are butted by adjusting the distance between the two support plates 9 in the horizontal direction, and then the construction formworks are clamped by the mutual matching of the upper clamping plate 10 and the lower clamping plate 11, so that the horizontal butting and clamping of the two construction formworks are realized by the mutual matching and the combined action of the support plates 9, the upper clamping plate 10 and the lower clamping plate 11; then, the two telescopic rods 14 extend upwards synchronously, and when the edge parts of the template are contacted with the two ends of the prestressed tendons extending out of the interior of the partitioning structure of the prestressed concrete beam body respectively, the two telescopic rods 14 stop moving upwards; then cylinder 16 upwards extends to take the altitude and stops, the laminating in the middle part of the stripper plate 17 top and template this moment, two telescopic links 14 support the template both ends respectively through lower plate 11, subsequently to the electro-magnet 31 circular telegram, thereby because the magnetism of circular telegram back flexible magnet 30 and electro-magnet 31 is different makes between flexible magnet 30 and the electro-magnet 31 mutual repulsion, through increaseing the circular telegram electric current gradually, make flexible magnet 30 upwards take place the bending, stripper plate 17 produces ascending extrusion force to the template middle part promptly, when the template moves to with the inside prestressing tendons middle part contact that stretches out of prestressing force concrete beam body segmentation structure, no longer change the size of circular telegram electric current. At the moment, under the mutual cooperation of the supporting plate 9, the upper clamping plate 10, the lower clamping plate 11, the telescopic rod 14 and the flexible magnet 30 and the electromagnet 31 and the combined action, the template generates deformation which is the same as the bending radian of the prestressed reinforcing steel extending out of the interior of the segmented structure of the prestressed concrete beam body, so that a concrete structure which is the same as the bending radian of the segmented structure of the prestressed concrete beam body is convenient to pour, the aims of enhancing the whole compression and tension resistance of the structure and preventing or delaying the occurrence of concrete cracks are fulfilled when the prestressed concrete beam is used.
When the template needs to be disassembled, firstly, the electromagnet 31 is stopped to be electrified, at the moment, the magnetism of the electromagnet 31 disappears, the repulsive force between the flexible magnet 30 and the electromagnet 31 also disappears, the flexible magnet 30 recovers to the original shape, namely, the extrusion force of the flexible magnet 30 on the template is relieved, then, the air cylinder 16 is contracted downwards, meanwhile, the air cylinder 16 drives the extrusion plate 17 to be far away from the template, then, the positions of the two support plates 9 are adjusted to be far away from each other, the two telescopic rods 14 are contracted downwards to drive the lower clamping plate 11 to be also far away from the template downwards, and finally, the template is conveniently disassembled from the connecting assembly.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
