A plugging plate and a plugging device for a grouting sleeve communicating chamber

Abstract

The invention discloses a plugging plate of a grouting sleeve communicating silo, comprising a baffle plate and a vertical fastening component. The baffle plate includes a vertical plate and a horizontal plate arranged perpendicular to each other, and the vertical plate is provided with a fixing hole; the vertical fastening The assembly includes an L-shaped support plate and an adjustment rod, the lower part of the L-shaped support plate is arranged opposite to the inner side of the vertical plate, and the end of the lower part of the L-shaped support plate is inserted into the fixing hole, and the first end of the adjustment rod is connected to the upper part of the L-shaped support plate. The hinge joint and the second end are pressed and arranged on the inner side surface of the horizontal plate. The invention also provides a plugging device for a grouting sleeve communicating bin, which is formed by combining more than two plugging plates, and the ends of the adjacent plugging plates are compressed and fixed by clips. The plugging device of this scheme is arranged at the joints of the upper and lower prefabricated components to form a closed empty warehouse to ensure that the grouting sleeve does not leak during the grouting process; it reduces the hidden danger of grouting quality; the installation is fast and convenient, no grouting is required during construction, and the construction efficiency is high. , can be used for multiple turnovers; fine-tuning range is reserved in both the horizontal and vertical directions, which is highly practical.

Description

Technical field[0001]The invention belongs to the technical field of building construction. Specifically, the invention relates to a plugging plate and a plugging device of a grouting sleeve communicating with a warehouse.Background technique[0002]In the construction of prefabricated buildings, the vertical prefabricated components can be connected to the upper and lower prefabricated components through the embedded sleeve grouting. During production, the upper prefabricated components, such as the shear wall and the bottom side of the prefabricated columns, are embedded with grouting sleeves. The top of the grouting sleeve is anchored with the stressed steel bars of the upper prefabricated components, and the bottom end is provided with a steel connection port; the top of the lower prefabricated components The stressed steel bars extend from the side. During construction, the stressed steel bars of the lower prefabricated component extend into the steel bar connection at the bottom...

AI Technical Summary

Problems solved by technology

The use of sitting grout to seal the edge of the upper and lower prefabricated component connecting warehouses has the following problems: 1. After hoisting and positioning the upper prefabricated component, it is necessary to wait for more than 12 hours to ensure that the slurry for the sitting grout solidifies, so the construction time is longer; 2. Due to the upper prefabricated component It cannot be put down completely at a uniform speed and smoothly, causing the bottom side of the upper prefabricated component to often disperse the sitting grout on the top side of the lower prefabricated component, which requires grouting in the later stage; 3. Since the uniformity of the sitting grout cannot be guaranteed, the weak parts are grouted in the sleeve When grouting, it is easy to crack and leak after being under pressure; 4. Due to the high pressure of the grouting sleeve during grouting, the grouting pressure is slightly higher, and the grouting position will burst, resulting in the need to suspend the grouting. Refill the grout at the sitting position and wait for it to solidify, delaying the construction progress
