Problems solved by technology

However, since the structure of the sleeve itself is similar to that of an ordinary round tube, its structural strength and fatigue resistance are limited, resulting in obvious defects in the mechanical properties of the building structure using this grouting sleeve, which needs to be improved

Embodiment 1

[0037] see attached figure 1 , A grouting metal corrugated pipe for reinforcing steel bar, including corrugated pipe sections with openings at both ends, the wall thickness of which is at least 2mm, the rib height is at least 3mm, and the wave distance is 32±2mm. According to the actual needs of different projects, the inner diameter of the above-mentioned corrugated pipe section is available in various specifications such as 65mm and 80mm.

[0038] The corrugated pipe section is provided with grouting holes and grouting holes perpendicular to its axial direction on the pipe wall near the openings at both ends. The grouting holes and the grouting holes are respectively vertically fixed with a grouting pipe and a grouting pipe; the grouting pipe and the grouting pipe have openings. At least 20mm inner diameter. At the same time, the clear distance between the grouting hole and the adjacent end of the corrugated pipe section should be at least 220mm, and the clear distance betw...

Embodiment 2

[0041] see attached figure 2 , a grouting metal corrugated pipe for reinforcing steel bar anchoring, which is basically the same as the structure of Example 1, except that one end of the corrugated pipe 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 corrugated pipe section.

[0042] The working principle of this embodiment is: in actual construction, the metal bellows is suitable for assembling the pier column and the bearing platform. Specifically, the metal corrugated pipe building is fixed in the platform; the end of the corrugated pipe section where the sealing plate is located is down, and the open end of the corrugated pipe section is up, which is used for inserting the main reinforcement on the pier column.

Embodiment 3

[0044] see attached image 3 , a grouting metal corrugated pipe for reinforcing steel bar, which is basically the same as the structure of Example 1, the difference is that: the grouting hole penetrates the corrugated pipe section along the axial direction of the vertical corrugated pipe section, and the grouting pipe is penetrated along the grouting hole in the bellows section. in the bellows section, and welded and fixed with the bellows section. In this way, the openings at both ends of the grouting pipe are respectively located on both sides of the corrugated pipe section in the radial direction, and respectively constitute an opening for grouting. At the same time, if Figure 4 As shown, a plurality of grouting slots evenly distributed around the circumference are also formed on the pipe wall of the grouting pipe located inside the corrugated pipe section. In addition, in order to ensure the grouting efficiency, the grouting pipe can be set in a structure with two ends ...

Abstract

The invention discloses a grouting metal corrugated pipe for reinforcing steel bar and a processing method thereof, and relates to the technical field of steel pipe processing. Among them, a grouting metal corrugated pipe for reinforcing steel bar includes a corrugated pipe section, and a grouting hole and a grouting hole are respectively opened on the side wall near the two ends of the corrugated pipe perpendicular to its axial direction; the grouting hole and the grouting hole A grouting pipe and a grouting pipe are respectively fixed at the place. A processing method of a grouting metal corrugated pipe for reinforcing steel bar anchoring comprises the steps of forming a corrugated pipe section, punching a hole, and fixing a grouting pipe and a grouting pipe. The invention provides a grouted metal corrugated pipe for steel anchorage and a processing method thereof, which can improve the anchorage strength of steel bars and the assembly strength of prefabricated parts, can fully ensure the safety performance of buildings, and is more flexible and convenient in construction.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing, in particular to a grouting metal corrugated pipe for steel bar anchoring and a processing method thereof. Background technique [0002] With the expansion of the concept of bridge prefabrication from the upper structure to the lower structure, the scope of prefabricated components has gradually covered the main bridge stress components such as the main prefabricated pier beam consolidation beam, cover beam, pier column and so on. In the existing prefabricated bridge system, the main beam 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, the column and the bearing platform is generally connected by inserting the embedded steel bar into the embedded sleeve. [0003] The invention patent application with the exi...
