no. 1 example

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

[0034] Enclosing device, it comprises several baffles 9, and baffles 9 are connected end to end to form a limiting cavity;

[0035] A positioning device, which is arranged in the limiting cavity, the positioning device includes a positioning tube 7, a through hole 701 is provided on the positioning tube 7, and the grouting pipe 5 and the exhaust pipe 3 are communicated on the positioning tube 7, More specifically, metal bellows are used for the grouting pipe 6 and the exhaust pipe 3 .

[0036] By setting the positioning device, it can be positioned during on-site grouting to ensure its verticality.

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

[0038] It also includes a diagonal bracing device, which includes triangular support rods 4, to ensure the maintenance molding strength after grouting.

[0039] The front end of the support rod ...

Abstract

The invention discloses a fabricated column positioning grouting device and method, and belongs to the field of buildings. The method comprises the following steps of S1, pre-embedding a positioning device at the bottom of a vertical central shaft of a structural column, and enabling a positioning pipe on the positioning device to exceed the bottom of the structural column so as to obtain a fabricated column; S2, embedding a positioning steel plate into the concrete surface, hoisting the fabricated column to the position above the positioning steel plate, erecting an inclined strut device, andthen fixing the positioning pipe in the positioning device to the positioning steel plate; S3, erecting a fence device on the outer wall of the fabricated column; and S4, performing grouting from a grouting pipe till grout overflows from an exhaust pipe, and fishing grouting. According to the fabricated column positioning grouting device and method, by arranging the positioning device, positioning can be conducted during on-site grouting, and the requirements for the position and perpendicularity of the positioning pipe are met; and by arranging the positioning steel plate with an identifier,secondary correction positioning is carried out, and the flatness of a poured product is guaranteed.

Description

technical field [0001] The invention relates to the construction field, in particular to an assembled column positioning grouting device and method. Background technique [0002] In recent years, my country has actively explored the development of prefabricated buildings. At present, most of the main frame structural columns are cast-in-place. The construction process is cumbersome and consumes a lot of labor, materials and time. Contents of the invention [0003] The purpose of the present invention is to at least solve one of the technical problems in the prior art, and provide an assembled column positioning grouting device and method. [0004] Technical solution of the present invention is as follows: [0005] An assembled column positioning grouting device, comprising: [0006] The enclosure device includes several baffles connected end to end to form a space-limiting cavity; [0007] The positioning device is arranged in the limiting cavity, the positioning device...
