Embodiment Construction

[0027] Attached below Figure 1-5 The present invention will be further described in detail, but not as a limitation to the present invention.

[0028] like Figure 3-5 As shown, a series sleeve connection structure of assembled prefabricated components of the present invention includes a series sleeve 4 and a connecting pipe 14, and a gap is provided between the assembled prefabricated upper component 1 and the lower component 8, and the upper component 1 and the lower component The pre-embedded ribs 3 of the upper component and the pre-embedded ribs 7 of the lower component are respectively arranged in 8, and the pre-embedded ribs 7 of the lower component extend into the upper component 1 and are connected with the pre-embedded ribs 3 of the upper component through the series sleeve 4. There are at least one set of series-connected sleeves 4, and each set of series-connected sleeves 4 is formed by connecting six sleeves in series through connecting pipes 14, and the two end...

Abstract

The invention relates to an assembly prefabricated component series-connection sleeve connecting structure and a grouting method thereof, and belongs to the field of residential PC industrialization.The assembly prefabricated component series-connection sleeve connecting structure comprises one or more sets of series-connection sleeves and connecting pipes; a gap is formed between an assembly prefabricated upper component and an assembly prefabricated lower component; each set of series-connection sleeves is formed by a plurality of sleeves which are connected in series through the corresponding connecting pipe, and the two ends of the connecting pipes are connected with upper openings and lower openings of the adjacent sleeves correspondingly; and a shear key forming groove is formed inthe bottom end of the upper component, communicates with the gap between the upper component and the lower component and is poured with a primary grouting material, and the series-connection sleeves are poured with secondary grouting materials. The grouting method of the assembly prefabricated component series-connection sleeve connecting structure comprises the steps: primary pouring, still standing and secondary pouring. The assembly prefabricated component series-connection sleeve connecting structure is improved based on a single-point grouting method, and has the characteristics of beingeasy to construct, excellent in performance and free of grouting defects.

Description

technical field [0001] The invention relates to a series sleeve connection structure of assembled prefabricated components and a grouting method, which belong to the field of residential PC industrialization and are mainly used in the connection of vertical prefabricated components of assembled structures, such as columns and shear walls. Background technique [0002] In prefabricated buildings, ensuring good integrity is an inevitable requirement for prefabricated buildings. According to the requirements of "Technical Regulations for the Application of Reinforced Sleeve Grouting Connections" (JGJ355-2015) and "Technical Regulations for Prefabricated Concrete Structures" (JGJ1-2014), when vertical components such as column components and wall components are grouted by grouting, the grouting The pressure needs to meet the requirements, and the single-point grouting method should be adopted. Figure 1-2 Two grouting methods of single point grouting method, figure 1 In the pr...
