Upper prefabricated member-lower prefabricated member butting structure and upper prefabricated member-lower prefabricated member combination face grouting method

Abstract

The invention provides an upper prefabricated member-lower prefabricated member butting structure and an upper prefabricated member-lower prefabricated member combination face grouting method, aiming to overcome the effect on structural safety due to the fact that failure to exhaust air in a hollow cavity leads to cavities formed in upper layer-lower layer combination faces finally when the combination faces of upper and lower shear walls and upper and lower frame columns are grouted. The upper prefabricated member-lower prefabricated member butting structure comprises an upper prefabricated member and a lower prefabricated member which are butted, the combination face of the two prefabricated members is grouted, and at least one of the prefabricated members is provided with an exhaust passage with one end extending out of the combination face of the prefabricated member and the other end extending out of other surfaces thereof. The upper prefabricated member-lower prefabricated member butting structure and the upper prefabricated member-lower prefabricated member combination face grouting method have the advantages that both structural safety and construction quality are guaranteed, and the butting structure and the grouting method are suitable for grouting of the combination face of the upper and lower prefabricated members.

Description

[0001] The invention relates to the field of building industrialization, in particular to a butt joint structure of upper and lower prefabricated parts and a method for grouting the joint surfaces of the upper and lower prefabricated parts. Background technique [0002] During the installation of prefabricated shear walls and frame columns, when the joint surfaces of the upper and lower shear walls and frame columns are filled with grout, since the air in the cavity cannot be discharged, the internal air pressure will also increase during the continuous grouting process. It is getting bigger and bigger, which will eventually lead to cavities in the joint surface of the upper and lower layers, which will affect the structural safety. Contents of the invention [0003] The invention overcomes the disadvantages in the prior art that when the joint surfaces of the upper and lower layers of shear walls and frame columns are filled with grout, the air in the cavity cannot be discha...
