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

Embodiment
[0022] First fix the wooden strips 11 on both sides of the grouting layer 4 with steel nails 12 to completely block the two sides of the grouting layer 4, and then fill the high-strength grouting material 5 and the grouting layer 4 until the high-strength grouting material 5 is completely solidified to reach a certain strength Finally, dismantle and reclaim wooden bar 11. The present invention uses wooden strips 11 as the lateral plugging material of the grouting layer 4 to ensure the flatness of one side of the grouting layer 4, to ensure that the high-strength grouting material 5 completely fills the grouting layer 4, and completely transmits the load between the upper and lower layers. During application, the wood type of the wooden strip 11, the cross-sectional size of the wooden strip 11, the material of the steel nail 12, and the size of the steel nail 12 are determined according to the actual stress situation of the project, such as Figure 3 ~ Figure 4 shown. The ...

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 sealing method for a grouting layer at the joint between upper and lower floors of a prefabricated shear wall building. Background technique [0002] The prefabricated shear wall structure building is a structural form that the country has focused on developing in recent years. The construction of buildings with prefabricated shear wall structures has the advantages of high construction quality, fast construction speed, saving materials, and saving human resources. It is an important part of the industrialization process of housing in my country. The key technology of this structural form lies in the connection between prefabricated shear wall panels, especially the vertical connection of prefabricated shear wall panels. [0003] At present, the connection structure between the upper and lower layers of the prefabricated shear wall in my country consists of upper shear wall 1...
