Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, in particular to a detachable connecting and fixing device for a bridge cap beam core rod and a temporary support. Background Art

[0002] The cap beam refers to the beam installed on the top of the frame pile pier to support, distribute and transfer the load of the bridge superstructure. The main function of the cap beam is to support the bridge superstructure and transfer all the loads to the lower structure. When constructing the cap beam, through rods, steel hoops or brackets are usually used. Among them, through rods have no requirements for the foundation and are not only suitable for the construction of cylindrical piers and rectangular piers, but also can save materials and labor and improve construction efficiency.

[0003] When using through-rods for construction, through holes are usually reserved on the piers. After the through-rods are passed through the reserved through holes, channel steels are welded on the through-rods, and then temporary supports (such as jacks, sand boxes, etc.) are set on the channel steels to support structures such as longitudinal beams and distribution beams. When setting temporary supports on the through-rods, the temporary supports are usually placed directly on the channel steels, or the temporary supports are welded to the channel steels; the temporary supports are placed directly on the channel steels, which have poor stability and are prone to displacement and tipping during the support process, and cannot provide stable support for the longitudinal beams and distribution beams; moreover, when the pressure center of the temporary support and its upper structure is not at the center of the through-rods, they are prone to tipping over, leading to safety accidents. When the temporary support is welded to the channel steel, the temporary support can only be used for specific piers under construction. After the construction of the cap beam is completed, it is difficult to remove the temporary support from the channel steel and make the temporary support circulate for use on other piers. Moreover, the channel steel is welded on the through rod. After the construction of the cap beam is completed, the through rod needs to be removed from the pier by cutting. The through rod is difficult to be completely removed from the pier and circulated for use on other piers, which is not conducive to the economy of construction. Utility Model Content

[0031] Since the fixing part 1 is detachably arranged on the through rod 2, after the construction of the cap beam is completed, the fixing part 1, the through rod 2 and the temporary support 3 can be quickly and conveniently removed from the pier. During the removal process, the through rod 2 and the temporary support 3 will not be damaged, thereby ensuring the structural integrity of the through rod 2 and the temporary support 3, so that the through rod 2 and the temporary support 3 can be circulated for use in other piers, which is beneficial to the economy of the cap beam construction.

[0032] refer to Figure 2The first fixing portion 11 is an inverted U-shaped structure, the top of which is a plane, and a first arc-shaped groove 110 is provided at the bottom. The top of the second fixing portion 12 is integrally connected to the bottom of the first fixing portion 11, and the second fixing portion 12 is a semicircular ring structure, the top of which is provided with a second arc-shaped groove 120, and the bottom is provided with a notch 121 connected to the second groove 120, and the left and right ends of the notch 121 are respectively provided with connecting plates 122, the cross-section of the connecting plate 122 is a rectangular structure, and the top thereof is integrally formed with the second fixing portion 12; one or more first connecting holes are provided in the length direction of the connecting plate 122, and the two connecting plates 122 are connected by bolts 4; locking or loosening the bolts 4 can reduce or increase the distance between the two connecting plates 122, so that the fixing member 1 can be stably fixed on the through rod 2 or removed from the through rod 2.

[0033] The top of the second fixing portion 12 can also be detachably connected to the bottom of the first fixing portion 11.
