2. The assembly type building pipeline embedded joint as claimed in claim 1, wherein: the length of the upper bellmouth (1) is longer than that of the lower bellmouth (2).

3. The pre-buried joint of assembly building pipeline of claim 1, wherein: the bottom of bellmouth (2) has flexible sealing mouth (11) down, has rubber seal (12) on the inner wall of flexible sealing mouth (11), and there is solid fixed ring (13) bottom of rubber seal (12), and the outer wall of rubber seal (12) has bellmouth groove (14), and bellmouth groove (14) internal diameter is greater than the internal diameter in bellmouth (2) middle part down, and the length of bellmouth (2) is longer than the length of last bellmouth (1) down.

Technical Field

The invention relates to a building embedded joint, in particular to an assembly type building embedded joint.

Background

The riser installation in the prefabricated building at present needs to adopt and reserves the hole, then installs the riser, and the installation operation flow in reuse concrete shutoff hole, and the pipeline will install layer by layer, and when the pipeline produced the damage, it is very difficult to change, and this mounting means adopts wet process operation, and the process is numerous and diverse, and the hole shutoff has the hidden danger of leaking easily.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides an assembly type embedded joint which can be directly embedded without reserving holes when a pipeline is installed in an assembly type building, and is extremely simple to install and replace the pipeline.

the invention relates to an assembly type building embedded joint, which comprises an upper bellmouth, a lower bellmouth and supporting legs, wherein the upper bellmouth is communicated with the lower bellmouth up and down, a convex ring with a convex inner wall is arranged at the communication position of the upper bellmouth and the lower bellmouth, a flexible interface with an inner wall larger than the inner wall of a middle section is arranged at the top of the upper bellmouth, an annular bell mouth is arranged at the top of the flexible interface, an external thread is arranged on the external thread, a gland with an internal thread is sleeved on the external thread, a pressing ring with a concave shape is arranged on the gland and out of the top of the inner wall of the gland, a rubber sealing ring is arranged below the pressing ring, three supporting legs are arranged at the bottom of the lower bellmouth, the middle of the three supporting legs is short, two sides of the three supporting legs are long, the included angle between the supporting legs at two sides and the supporting leg at the middle is 15 ~ 40 degrees, a fixing head is arranged at the top of the supporting legs, the fixing head is a convex head or a concave head, the orientation of the fixing head at two supporting legs 3 is combined with the orientation of the middle fixing head, when the supporting legs is not in advance, the installation space, two supporting legs, the installation space of a building vertical pipe can be reasonably arranged, the installation space, two supporting legs can be reduced, and the installation space can be used when the vertical pipe, the installation space of the vertical pipe, and the vertical pipe can be reasonably used, and the vertical pipe.

According to the fabricated building embedded joint, the length of the upper bellmouth 1 is longer than that of the lower bellmouth 2, the structure is combined with the characteristics that the upper bellmouth is a flexible interface, a rubber ring and a threaded gland are arranged in the flexible interface, and the like, when a product is used, the product is only embedded in a floor slab on the ground, holes are not required to be reserved in the floor slab, and the assembly, disassembly and replacement operations are very convenient.

The invention relates to an assembly type building embedded joint, wherein a flexible sealing port is arranged at the bottom of a lower bell mouth, a rubber sealing ring is arranged on the inner wall of the flexible sealing port, a fixing ring is arranged at the bottom of the rubber sealing ring, a bell mouth groove is arranged on the outer wall of the rubber sealing ring, the inner diameter of the bell mouth groove is larger than that of the middle part of the lower bell mouth, the length of the lower bell mouth is longer than that of the upper bell mouth.
