Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water pipe penetrating floor slab structures, in particular to a water pipe penetrating floor slab node. Background Art
[0002] During construction, it is common for water pipes to pass through the floor. During the installation process, the center of the water pipe often does not coincide with the center line of the casing, that is, the water pipe is eccentric in the casing. According to traditional practices, a layer of insulation should be wrapped around the outside of the water pipe, and the insulation layer usually uses insulation cotton. Due to the eccentricity during installation, the insulation cotton cannot pass through the casing, resulting in uneven circumferential insulation of the water pipe, affecting the overall effect of the air-conditioning system. In severe cases, it will cause leakage of frozen water pipes or condensed water on the outer wall of the water pipe, which will pass through the casing and drip to the lower floor, affecting the quality of engineering decoration and even causing serious consequences such as short circuit of important instruments. Since the installation offset will also affect the sealing operation between the water pipe and the floor, water leakage is likely to occur at this part during subsequent use, causing a certain amount of damage to the user.

[0017] The utility model is further described below in conjunction with the accompanying drawings:
[0018] like Figure 1 , Figure 2 and Figure 3 The water pipe through floor node shown in the figure comprises a casing 2 pre-buried in the floor 1 and a water pipe 3 passing through the casing 2. During construction, the casing 2 is a steel casing. A plurality of fixing ribs 4 are fixedly arranged on the outer circumference of the casing 2 by welding. The fixing ribs 4 are pre-buried in the floor 1. In one embodiment, four fixing ribs 4 are fixedly arranged on the outer circumference of the casing 2. Of course, three, five or six fixing ribs 4 can also be arranged.
[0019] A plurality of centering components 5 are fixedly arranged on the outer circumference of the water pipe 3 by welding. The centering component 5 includes a housing 50 fixedly arranged on the outer side of the water pipe 3 by welding, a plurality of centering ejector rods 51 slidably mounted on the housing 50, and a top block 52 vertically slidably mounted in the housing 50. One end of the centering ejector rod 51 is in contact with the top block 52. The vertical sliding of the top block 52 can drive the centering ejector rod 51 to horizontally extend to the outside of the housing 50 and abut against the inner wall of the sleeve 2. In one embodiment, four centering components 5 are arranged on the outer circumference of the water pipe 3 at the position corresponding to one sleeve 2. Of course, three, five or six centering components 5 can also be arranged. The plurality of centering ejector rods 51 are vertically spaced. A return spring 53 is arranged on the centering ejector rod 51. One end of the return spring 53 abuts against the inner side of the housing 50, and one end of the return spring 53 abuts against a protrusion on the centering ejector rod 51.
