Embodiment 1

[0037] See attached figure 1 What is claimed is a grouted metal bellows for steel bar anchoring, comprising a bellows section open at both ends, having a wall thickness of at least 2mm, a rib height of at least 3mm, and a wave pitch of 32±2mm. According to the actual needs of different projects, the inner diameter of the bellows section is available in various specifications such as 65mm and 80mm.

[0038] The bellows section is provided with a grouting hole and a grouting hole perpendicular to the axial direction on the pipe wall close to the opening at both ends, and the grouting hole and the grouting hole are respectively vertically fixed with a grouting pipe and a grouting pipe; the opening of the grouting pipe and the grouting pipe At least 20mm inside diameter. At the same time, the net distance between the grouting hole and the adjacent end of the bellows section is at least 220mm, and the net distance between the grouting hole and the adjacent end of the bellows secti...

Embodiment 2

[0041] See attached figure 2 , a grouting metal bellows for steel bar anchoring, which is basically the same in structure as in Example 1, the difference being that one end of the bellows section is open, and the other end is welded and fixed with a sealing plate. Specifically, the sealing plate can be arranged at the end where the grouting hole is located, and can effectively seal the corresponding port of the bellows section.

[0042] The working principle of this embodiment is: in actual construction, the metal bellows is suitable for the assembly of pier columns and caps. Specifically, the metal bellows building is fixed in the cap; the upper end of the bellows section where the sealing plate is located is at the bottom, and the opening end is at the top, which is used to insert the main reinforcement on the pier column.

Embodiment 3

[0044] See attached image 3 , a grouting metal bellows for steel bar anchoring, its structure is basically the same as that of Example 1, the difference is that: the grouting hole runs through the bellows section along the direction vertical to the axial direction of the bellows section, and the grouting pipe is pierced along the grouting hole in the The bellows section is welded and fixed with the bellows section. In this way, the openings at both ends of the grouting pipe are respectively located on both radial sides of the corrugated pipe section, and respectively constitute an opening for grouting. At the same time, if Figure 4 As shown, the wall of the grouting pipe located inside the corrugated pipe section is also provided with a number of grouting notches evenly distributed around the circumference. Moreover, in order to ensure the grouting efficiency, the grouting pipe can be set in a structure with thin ends and a thick middle, that is, the inner diameter of the ...

Abstract

The invention discloses a grouting metal corrugated pipe for steel bar anchoring and a machining method thereof, and relates to the technical field of steel pipe machining. The grouting metal corrugated pipe for steel bar anchoring comprises a corrugated pipe section, and a grouting hole and a grout outlet hole are formed in the side walls, close to the two ends of the corrugated pipe, of the corrugated pipe in the direction perpendicular to the axial direction of the corrugated pipe. A grouting pipe and a grout outlet pipe are respectively fixed at the grouting hole and the grout outlet hole.The invention discloses a machining method of the grouting metal corrugated pipe for steel bar anchoring. The machining method comprises the steps of corrugated pipe section forming, punching, grouting pipe and grout outlet pipe fixing and the like. According to the invention, the steel bar anchoring strength and the prefabricated part assembling strength can be improved, the building safety performance can be fully guaranteed, and construction is more flexible and convenient.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing, in particular to a grouting metal bellows for steel bar anchoring and a processing method thereof. Background technique [0002] With the expansion of the concept of prefabricated bridges from the superstructure to the substructure, the scope of prefabricated components has gradually covered the main bridge stress components such as main prefabricated assembled pier beam consolidation beams, cover beams, and pier columns. In the existing prefabricated bridge system, the main girder rests on the cover beam through the support, and the cover beam is consolidated with the pier column to transfer the load of the superstructure to the foundation. Among them, the combination of the cover beam and the column, and the column and the platform is generally connected by inserting the embedded steel bar into the embedded sleeve. [0003] The existing patent application with publication number ...
