[0032] Reference Figures 1 to 3 , the first embodiment of the present invention:

[0033] An assembled column positioning grouting device, comprising:

[0034] The enclosure device comprises a plurality of baffles 9, which are connected end to end to form a limiting cavity;

[0035] The positioning device is arranged in the limiting cavity, and the positioning device includes a positioning tube 7, on which a through hole 701 is arranged, and the positioning tube 7 is connected to a grouting tube 5 and an exhaust pipe 3. More specifically, the grouting tube 5 and the exhaust pipe 3 are metal bellows.

[0036] By setting the positioning device, it is possible to position during on-site grouting to ensure its verticality.

[0037] As a first embodiment of the present invention, it may also have the following additional technical features:

[0038] It also includes an oblique support device, which includes a triangular support rod 4 to ensure the curing and forming strength after grouting.

[0039] The front end of the support rod 4 is provided with a top block 401 to increase the contact area and provide a better support effect.

[0040] A positioning steel plate 8 is arranged below the positioning tube 7 , and a positioning mark is arranged on the upper surface of the positioning steel plate 8 for facilitating positioning.

[0041] The positioning tube 7 is provided with positioning steel bars 6 arranged in a horizontal cross shape, and the position and verticality of the positioning tube 7 are ensured after multiple positioning corrections.

[0042] There are 2 to 5 through holes, which are evenly distributed on the outer wall of the positioning tube 7 to facilitate slurry entry.

[0043] The through hole 701 is in the shape of a water drop, which gradually increases from top to bottom. When the slurry is fed, the slurry first flows out from the larger opening due to pressure. This setting can reduce the bubbles generated when the slurry is fed.

[0044] The second embodiment of the present invention is a method for positioning and grouting a prefabricated column, comprising the following steps:

[0045] Step 1: pre-embed a positioning device at the bottom of the vertical central axis of the structural column 10, and the positioning tube 7 on the positioning device exceeds the bottom of the structural column 10 to obtain an assembled column;

[0046] Step 2: embed a positioning steel plate 8 in the concrete surface, hoist the assembled column above it, set up a diagonal bracing device on the concrete surface, support the outer wall of the assembled column with the support rod 4, and then weld the positioning tube 7 in the positioning device to the positioning steel plate 8;

[0047] Step 3: Install enclosure devices on the outer wall of the assembled column;

[0048] Step 4: Grouting is performed from the grouting pipe 5 until the exhaust pipe 3 overflows, and the grouting is completed.

[0049] In the step 1, the inner wall of the structural column 10 is pre-embedded with steel bars 1 and stirrups 2 arranged horizontally and vertically, and the steel bars 1 extend beyond a portion of the bottom surface of the structural column 10 .

[0050] In the step three, after the enclosure device is installed on the outer wall of the assembled column, the gap between the outer wall of the assembled column and the enclosure device is filled with sealing material; and / or;

[0051] The step 4 also includes the steps of maintaining and removing the diagonal bracing device and the enclosure device.

[0052] In a specific application, in a precast component factory, a structural column 10 is precast according to the specification dimensions. During prefabrication and processing, a positioning pipe 7 with openings on all four sides at the bottom of the vertical central axis of the structural column 10 is embedded. Specifically, it is made of a steel pipe above DN100 and two metal bellows for the exhaust pipe 3 and the grouting pipe 5. Two steel bars are used to position the positioning pipe 7 to ensure that the position and perpendicularity of the steel pipe meet the requirements. A positioning steel plate 8 with positioning marks is embedded on the joint surface between the bottom of the structural column 10 and the slab (or other components). This setting serves as a secondary correction to ensure the flatness and firmness of the grouting. At this time, an assembled column is obtained. After the assembled column is hoisted to a certain distance above the corresponding position, with the assistance of a towing rope, the assembled column is slowly lowered until the central axis of the positioning pipe 7 coincides with the positioning mark, and then the support rod 4 is set up for secondary correction of the positioning and perpendicularity. After the correction is completed, the welder welds the positioning pipe 7 firmly to the embedded positioning steel plate 8. A baffle 9 is set up at the bottom of the assembled column, and sealing materials are arranged around the bottom of the baffle 9. After the above procedures are completed, a grouting machine is used to grout under pressure from the grouting pipe 5, and the grouting ends when the slurry overflows from the exhaust pipe 3. Finally, the bottom grouting area is cured, and after passing the inspection, the support rod 4 and the baffle 9 are removed.

[0053] On the premise of no conflict, those skilled in the art can freely combine and superimpose the above additional technical features.

[0054] In the description of the embodiments of the present invention, it should be understood that "-" and "~" represent the range between two numerical values, and this range includes the endpoints. For example: "A - B" represents a range greater than or equal to A and less than or equal to B. "A ~ B" represents a range greater than or equal to A and less than or equal to B.

[0055] In the description of the embodiments of the present invention, the term "and / or" herein only describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the front and rear associated objects.

[0056] The above is only the preferred implementation mode of the present invention. As long as the technical solutions that achieve the purpose of the present invention by basically the same means fall within the protection scope of the present invention.
