Description

A device for improving vertical grouting fullness of prefabricated components

technical field

The utility model relates to a device, in particular to a device for improving the plumpness of vertical grouting of prefabricated components.

Background technique

At present, my country is vigorously promoting prefabricated buildings, and various architectural design and construction companies are also actively responding to the national call. However, because the development of prefabricated buildings in China has just started, the construction experience and technical talents of prefabricated buildings are seriously insufficient, and the plumpness of vertical structure grouting construction is controlled. There is still a lack of good solutions, resulting in poor longitudinal connection quality of prefabricated columns and prefabricated shear walls.

SUMMARY OF THE INVENTION

Purpose of the invention: The purpose of this utility model is to provide a device for improving the plumpness of vertical grouting of prefabricated components in view of the deficiencies of the prior art.

Technical scheme: The device for improving the vertical grouting fullness of prefabricated components according to the present utility model includes a bracket on which a hard pipe is longitudinally installed, and a pressure-limiting safety valve is connected to the side of the hard pipe, and a The manual valve below the pressure-limiting safety valve; the pressure-limiting safety valve and the manual valve are all connected with the pulping hose; the top of the rigid pipe is installed with a closed nut, and the bottom is connected with a pulping hose; The inside of the tube is provided with a sealing plug.

Preferably, the rigid pipe is a PVC rigid pipe.

Preferably, the hard pipe is mounted on the bracket through several limit snap rings.

Preferably, the pressure limiting safety valve is connected with a hard pipe through a tee.

Preferably, the manual valve is connected with a hard pipe through a tee.

Preferably, the rigid tube is in an L-shaped structure.

Preferably, the sealing plug is a rubber sealing plug.

Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model effectively solves the common problems such as the incompact and full grouting material in the grouting process, and at the same time has the advantages of simple structure, simple operation, convenient carrying and low production cost. , High grouting pass rate.

Description of drawings

FIG. 1 is a structural diagram of an embodiment of the present invention.

In the drawings, 1- bracket, 2-PVC rigid pipe, 3-limiting snap ring, 4-three-way, 5-pressure limiting safety valve, 6-manual valve, 7-slurry hose, 8-closed nut , 9- into the slurry hose, 10- rubber sealing plug.

Detailed ways

The technical solutions of the present invention will be described in detail below through specific embodiments and accompanying drawings, but the protection scope of the present invention is not limited to the embodiments.

Example

A device for improving the plumpness of vertical grouting of prefabricated components, referring to FIG. 1 , includes a bracket 1 , an L-shaped PVC hard pipe 2 is installed on the bracket 1 in the longitudinal direction, and the PVC hard pipe 2 is installed on the bracket through three limit snap rings 3 . 1, the three limit snap rings are respectively located on the upper, middle and lower parts of the hard pipe 2; ; The pressure limiting safety valve 5 and the manual valve 6 are all connected with the pulping hose 7; the top of the PVC rigid pipe 2 is provided with a screw-on closing nut 8, and the bottom is connected with a pulping hose 9; the interior of the PVC rigid pipe 2 A rubber sealing plug 10 is provided.

In the implementation of this embodiment, before grouting, push the rubber sealing plug 10 to be flush with the upper opening of the manual valve 6, and then tighten the screw cap to close the nut 8. During grouting, the air in front of the rubber sealing plug 10 is discharged through the manual valve 6 and the grouting material with bubbles, then close the manual valve 6, the grouting material pushes the rubber sealing plug 10 to the upper part of the pressure-limiting safety valve 5, and the pressure-limiting safety valve 5 ensures that the grouting material is always under constant pressure (the pressure is slightly less than the grouting pressure). After grouting, before plugging the grouting outlet, the grouting material is recharged under pressure to ensure that the grouting bin is always full.

As mentioned above, although the present invention has been shown and described with reference to specific preferred embodiments, this should not be construed as limiting the invention itself. Various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
