Problems solved by technology

However, at present, the grouting sleeves are all poured into the upper prefabricated component in the prefabricated component factory, and the connecting steel bars between the lower prefabricated component and the upper prefabricated component are always exposed outside, and the poured prefabricated components are then transported to the site for storage. The steel bars of prefabricated components have been exposed for a long time. The steel bars in some prefabricated components are too long, which is not convenient for transportation, storage and safe construction. , affecting on-site assembly operations, not only is not conducive to construction efficiency, but may even cause engineering accidents due to leakage of steel bars

Embodiment 1

[0030]Seefigure 1 In this embodiment, a spliced ​​grouting sleeve includes: a first sleeve 2, a second sleeve 1, a connecting steel bar 3, and a grout 14; a section of the connecting steel bar 3 is contained in the first sleeve 2. , The other section of the connecting steel bar 3 is contained in the second sleeve 1. The connecting steel bar 3 is used to connect the first sleeve 2 and the second sleeve 1. The first sleeve 2 is close to the port of the second sleeve 1 and the second sleeve 1. The sleeve 1 is spliced ​​close to the port of the first sleeve 2, and the grout 14 is filled in the sleeve cavity 11 formed by the first sleeve 2 and the second sleeve 1;figure 1 In the state where the grouting sleeve is to be spliced, the sleeve cavity 11 of the first sleeve 2 and the second sleeve 1 is not filled with grout 14.

[0031]The first sleeve 2 and the second sleeve 1 can be completely the same in length and shape, or they can be different. It is only necessary to ensure that the size o...

Embodiment 2

[0048]The second embodiment provides a prefabricated building component, which includes a load-bearing main body and a splicable grouting sleeve. One end of the splicable grouting sleeve is detachably connected to the embedded steel bar of the load-bearing main body, and the other end of the splicable grouting sleeve For the open end, the splicable grouting sleeve is provided with a slurry port. The bearing body can be a shear wall or a prefabricated column.

[0049]In construction projects, shear walls are mainly subjected to horizontal and vertical loads caused by wind loads or earthquakes to prevent structural shear damage. Therefore, shear walls are particularly important in earthquake-prone areas and other areas. The upper and lower prefabricated components can be shear walls, seeimage 3 withFigure 4 , The spliced ​​grouting sleeve is used for prefabricated shear wall components. Since the connecting steel bar 3 and the prefabricated shear wall can be transported and stored separa...

Abstract

The invention discloses a spliced grouting sleeve which comprises a first sleeve, a second sleeve and a connecting steel bar, the first sleeve and the second sleeve can be spliced into a complete grouting sleeve, the connecting steel bar is used for connecting the first sleeve and the second sleeve, and a sleeve cavity of the first sleeve and a sleeve cavity of the second sleeve are filled with grouting materials; one end, far away from the second sleeve, of the first sleeve is provided with a first connecting end, and the first connecting end is detachably connected with an embedded steel barof a first prefabricated part; a second connecting end is arranged at the end, away from the first sleeve, of the second sleeve, and the second connecting end is detachably connected with an embeddedsteel bar of a second prefabricated part; and the first sleeve is provided with a grouting opening, and the second sleeve is provided with a slurry discharging opening. The grouting sleeve can effectively avoid the problems that in an assembly type building, due to the fact that steel bars are exposed, prefabricated parts are deformed and damaged and the steel bars are rusted and bent, and therefore transportation and storage are convenient.

Description

Technical field[0001]The invention belongs to the field of prefabricated buildings, and particularly relates to a splicing grouting sleeve and a prefabricated building component.Background technique[0002]With the gradual realization of the industrialization of the construction industry in my country, the emerging prefabricated construction method has greatly reduced the original cast-in-place operation through a large number of on-site assembly operations, increased the construction speed, reduced material consumption and environmental pollution, and met the requirements of green buildings. The new direction of the development of my country's construction industry. At present, the grouting sleeve is used as the main component of the interconnection between prefabricated components in the prefabricated house. The grouting sleeve connection technology is mature and is one of the key and core technologies of the prefabricated concrete frame structure.[0003]The grouting sleeve connectio...
