The waterproof being packed in wall pipe is filled out embedding.
According to the wall pipe of different-diameter and the cable through walls of varying number, the utility model can be by with semicircle
The the first drag piece and the second drag piece of through hole ensure construction quality with carrying out maximum efficiency, reduce cost.
Brief description of the drawings
Fig. 1 is the entirety according to the tubular construction through walls with new drag piece of a preferred embodiment of the present utility model
Schematic diagram；
Fig. 2 is the structural representation of Fig. 1 drag piece component.
Embodiment
Below in conjunction with the accompanying drawings, preferred embodiment of the present utility model is provided, and is described in detail.
Fig. 1 is the entirety according to the tubular construction through walls with new drag piece of a preferred embodiment of the present utility model
Schematic diagram, including reinforced concrete wall 1, wall pipe 2, cable through walls 3, drag piece component 4, fire prevention fill out embedding 5 and waterproof fill out it is embedding
6.Wherein, wall pipe 2 is embedded in reinforced concrete wall 1, is passed through for cable 3 through walls.In protective zone, drag piece group
Part 4 is fixed on one end of wall pipe 2.In wall pipe 2, the side for closing on exterior wall is packed with fire prevention and fills out embedding 5, is closing on
The side of protective zone is packed with waterproof and fills out embedding 6.The fire prevention fill out embedding 5 and waterproof fill out embedding 6 direct neighbor.
Fig. 2 is the structural representation of Fig. 1 drag piece component 4, including the relatively independent stacked He of the first drag piece 41
Second drag piece 42, wherein, the first drag piece 41 reclines one end of wall pipe 2, the first drag piece and the second drag piece 42 reclines
41 are installed.
First drag piece 41 has circular body 41a, and its middle part has a circular through hole 411 and three the first half
Circular through hole 412, this three the first semicircular through-holes 412 are evenly distributed on the circumference of circular through hole 411, and
Connected with circular through hole 411.In addition, two on straight line are additionally provided with the body 41a of the first drag piece 41
First fastener through hole 413.
Second drag piece 42 has circular body 42a.The body 41a of body 42a and the first drag piece 41 size
Corresponding, it has three grooves 421, and three grooves 421 are uniformly distributed, and is recessed respectively from body 42a circumference towards the center of circle
Formed, the bottom of its groove is formed as the second semicircular through-holes 422.Second semicircular through-holes 422 and first are semicircle
