Plugging method for grout blanket at connecting position of upper layer and lower layer of assembling shear wall building

Abstract

A plugging method for a grout blanket at a connecting position of an upper layer and a lower layer of an assembling shear wall building relates to a manufacturing method of a building structure. The method includes that first wood strips 11 are fixed on two sides of the grout blanket 4 through steel nails 12 to plug the two sides of the grout blanket 4 completely, then a high-strength grouting material 5 is filled in the grout blanket 4, and finally after the high-strength grouting material 5 is completely condensed to reach certain strength, the wooden strips 11 can be detached and recycled. The plugging method is suitable for a structure form at the connecting position of the upper layer and the lower layer of an assembling shear wall building structure. By using the wood strips for plugging, the surface of one side of the grouting blanket can be guaranteed to be smooth, the high-strength grouting material can fill the grouting blanket completely, and load between the upper layer and the lower layer is delivered completely. The toughness of the wood strips is better than that of cement mortar, and the wood strips have good impact resistance. The wood strips are convenient to prefabricate and install, suitable for assembling building construction and capable of being recycled, and materials are saved.

Description

Technical field [0001] The invention relates to a building construction method, in particular to a method for plugging a grouting layer at the connection between the upper and lower floors of a fabricated shear wall building. Background technique [0002] The prefabricated shear wall structure building is a structural form that the country has developed in recent years. The use of fabricated shear wall structure to construct buildings has the advantages of high building quality, fast construction speed, saving materials, and saving human resources. It is an important part of the process of residential industrialization in my country. The key technology of this structure is the connection between prefabricated shear wall panels, especially the vertical connection of prefabricated shear wall panels. [0003] At present, the connection structure between the lower layers of the assembled shear wall in my country is composed of the upper shear wall 1, the bottom sleeve of the shear wa...

AI Technical Summary

Problems solved by technology

The disadvantage of this mortar sealing method is that the lateral sealing mortar 10 cannot guarantee the flatness of one side of the grouting layer 4 during construction, and the sealing mortar 10 will invade into the grouting layer 4, so that the high-strength grouting material 5 cannot guarantee the filling. Filling the entire grouting layer 4 affects the strength of the entire grouting layer 4, and cannot guarantee the smooth transmission of vertical loads between the upper and lower layers
