A vertical construction node of prefabricated components and its construction method

Abstract

The present invention provides a vertical construction node of a prefabricated component, which includes a first prefabricated component located above and a second prefabricated component located below, and also includes an elastic seal and a clip. The elastic seal is arranged between the first prefabricated component and the second prefabricated component. At the edge of the seam between the prefabricated components, the clip is set on the outer periphery of the elastic seal. The present invention also provides a construction method for the node, including steps: S1, hoisting the second prefabricated component and installing and fixing it, and setting pads on the surface of the second prefabricated component; S2, hoisting the first prefabricated component and setting it at a predetermined position, the second Stress tendons on the top side of the prefabricated component extend into the grouting sleeve on the bottom side of the first prefabricated component; S3, install elastic seals on the edge of the joints of the prefabricated components, and set clamps to fix the elastic seals; S4, inject Inject high-strength mortar into the slurry port, and after it is solidified and formed, remove the clip and remove the elastic seal. In this scheme, the connected warehouse is not easy to explode, the seals can be used repeatedly, the versatility is strong, and the construction steps are simple.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a construction method for vertical construction nodes of prefabricated components. Background technique [0002] In the construction of prefabricated buildings, pre-embedded sleeve grouting can be used between prefabricated components to realize the reinforcement connection between adjacent prefabricated components. The connection between the upper and lower prefabricated columns is taken as an example. By pre-embedding the grouting sleeve at the bottom of the upper precast column, the top of the grouting sleeve is anchored to the pre-embedded stressed steel bar in the upper precast column, and the bottom end is provided with a steel bar connection. mouth. During construction, the upper and lower prefabricated columns are assembled, and the steel bars of the lower prefabricated components extend into the steel bar connection ports at the bottom of the grouting sl...

Problems solved by technology

[0003] In the prior art, because of the high pressure in the connecting chamber between the two prefabricated components, when high-strength mortar is injected into the grouting sleeve, the solidified and formed slurry around the connecting chamber is prone to damage and bursting occurs, while the grouting sleeve During grouting, the high-strength mortar continuously leaks from the burst chamber, which affects the construction progress and quality; resulting in incomplete grouting in the grouting sleeve, and the connection quality of the grouting sleeve cannot be guaranteed, which in turn affects the connection strength of prefabricated components

At present, there is a lack of simple, efficient, versatile and easy-to-operate construction methods for this technical problem.
