Prior to the description, the biggest feature of the present invention is to make the connection with the vacuum pipe (B) installed between each layer through the slope correction of the vacuum pipe (B), to prevent the spread of fire to the upper layer in the event of a fire, the sleeve The biggest feature is that the vacuum pipe (B) fixed to the 120 to maintain exactly 90 degrees.

Vacuum pipe support device 100 of the present invention is installed in the drilling hole (S2) formed to penetrate the concrete slab (S1) forming a layer, and at the same time stable and support the vacuum pipes (B) pre-installed in the upper and lower layers Make sure the connection is established.

At this time, the connection between the vacuum pipes (B) is made through a flange (not shown).

In the vacuum pipe support device 100 of the present invention, as shown in Figure 1, the embedding 110 is seated in the drilling hole (S2) of the concrete slab (S1), the sleeve 120 is accommodated in the embedding 110, the sleeve A vacuum pipe (B) having a predetermined length is fixed perpendicularly to the center portion, and an expansion fireproof member (130) is provided below the vacuum pipe (B).

At this time, the embed 110 is made of aluminum, the sleeve 120 is made of stainless steel.

The embedding 110 has a circular shape as a whole in the form of a plate having a predetermined height, as shown in Figures 2 to 4, the circumference of the circular forms a stepped portion 111 having a predetermined height, The inside of the jaw portion 111 is recessed to a predetermined depth.

The recessed inner bottom is provided with a seating piece 112 having a predetermined area along the inner circumference, and a circular through hole 113 through which the vacuum pipe B penetrates is formed at the center of the seating piece 112. have.
