Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-6, a prefabricated building component comprises a lower component 1, an upper component 2 is arranged at the top end of the lower component 1, a slurry discharge port 3 and a slurry filling port 4 are respectively arranged inside the upper component 2, the slurry discharge port 3 and the slurry filling port 4 are located on the same central line, a connecting mechanism 5 is fixedly installed inside the upper component 2, the connecting mechanism 5 is respectively communicated with the slurry discharge port 3 and the slurry filling port 4, and a kidney-shaped hole 6 is arranged between the slurry discharge port 3 and the slurry filling port 4.

In this technical scheme, coupling mechanism 5 includes adapter sleeve 51, coupling bar I52, sealed dog 53, coupling bar II54 and waist type bayonet lock 55, adapter sleeve 51 is located the inside of upper member 2, adapter sleeve 51's top is equipped with coupling bar I52, and the top of coupling bar I52 and the inside fixed connection of upper member 2, the top of adapter sleeve 51 inner chamber is equipped with sealed dog 53, adapter sleeve 51's bottom is equipped with coupling bar II54, and the bottom of coupling bar II54 and the inside fixed connection of lower member 1, through waist type bayonet lock 55 fixed connection between coupling bar I52 and the coupling bar II 54.

In this technical solution, a colloid insoluble in cement slurry is disposed in the inner cavity of the connection sleeve 51.

Wherein, before the inside grout of adapter sleeve 51, pour into the colloid in adapter sleeve 51's inner chamber into earlier, utilize grout to extrude the colloid in adapter sleeve 51 inner chamber during the grout, be used for discharging the air in the adapter sleeve 51 inner chamber, can effectually prevent when the inner chamber to adapter sleeve 51 is groud, the air in its inner chamber still persists in grout to produce the gas pocket in fixed grout, and then serious influence grout is to the joint strength between lower component 1 and the upper member 2.
