Description

Wall rigid waterproof pipeline

Technical Field

The utility model belongs to the technical field of building construction, and particularly relates to a wall rigid waterproof pipeline.

Background

The rigid waterproof sleeve is a sleeve and a pipeline which are plugged by a rigid material to achieve a sealing effect, and is suitable for parts of a bearing wall or a structural wall which need to be paved with pipelines and are required to be waterproof. The existing rigid waterproof sleeve generally adopts a structure that a sleeve and a steel pipe are sleeved, and a rigid waterproof material is filled between the sleeve and the steel pipe. The existing rigid waterproof sleeve exists in the long-term use process: 1. the sealing effect is reduced because the cracks between the wall and the pipe sleeve are gradually increased. 2. The filled waterproof material has poor flame retardant capability, and the condition that fire spreads along the pipeline can occur.

Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model. Furthermore, the description of the vertical, horizontal, top, bottom, etc. positional relationships in the present utility model merely represents the relative positions of the components and is not an absolute position in any state.

Example 1

A wall rigid waterproof pipeline, as shown in fig. 1, comprising: line 1. The pipeline 1 is sleeved with a rigid sleeve 2, and a distance of 20-40mm is arranged between the outer wall of the pipeline 1 and the inner wall of the rigid sleeve 2 according to the thickness of the pipeline 1.

The part of the rigid sleeve 2 in the wall 7, the outer side wall of which is fixed with a wing ring 3 along the radial direction of the pipeline 1. A positioning ring 6 is fixed on the outer side wall of the pipeline 1. The position between the outer wall of the pipeline 1 and the inner wall of the rigid sleeve 2 is filled with hemp 4 at the positioning ring 6, and the rest is filled with asbestos cement 5. The adjacent distance between the oil hemp 4 is 50-80cm, preferably 60cm.

When the wing ring 3 is inserted into the wall body 7 during use, when cracks are gradually generated between the wall body 7 and the rigid sleeve 2 due to different thermal expansion coefficients, the wing ring 3 can play a good role in leakage prevention and blocking, so that leakage liquid penetrating into the cracks is blocked at the wing ring 3, and continuous penetration is difficult. In addition, the filled asbestos cement 5 plays a good rigid supporting role and has good waterproof and flame-retardant properties, so that the fire is difficult to spread along the pipeline. The filled hemp 4 has good waterproof and bending adaptability, so that when the deformation of the pipe sleeve receiving wall body acts, bending deformation with a certain extent can be carried out at the filling layer of the hemp 4 to adapt to the deformation of the wall body, and the problems of pipeline 1 damage or rigid filling material compression damage caused by the fact that the rigid filling material cannot be effectively adapted to the deformation when the rigid sleeve 2 deforms, and the resulting tightness is reduced or lost are avoided. The added positioning ring 6 can obviously increase the movement blocking capability of the hemp 4 between the pipeline 1 and the rigid sleeve 2, so that the hemp 4 is not easy to swim between the pipeline 1 and the rigid sleeve 2, and the problem of reduced or lost tightness caused by oversized gaps generated by the swimming of the hemp 4 is avoided.

Example 2

Based on the wall rigid waterproof pipeline in embodiment 1, a minimum distance K1 and a maximum distance K2 are arranged between the wing rings 3, and a minimum distance K3 and a maximum distance K4 are arranged between the wing rings 3 and two edges of the wall 7 along the axial direction of the rigid sleeve 2. When the length of the part of the rigid sleeve 2 in the wall 7 is greater than K1 x N+K2 x 2, the rigid sleeve 2 is provided with N wing rings 3 in the wall 7, the interval M1 between each wing ring 3 is K1 < M1 < K2, and the interval M2 between the two wing rings 3 at the edge and the two edges of the wall 7 along the axial direction of the rigid sleeve 2 is K3 < M2 < K4.

Each wing ring 3 can form a penetration barrier, so that the penetration resistance of the wall body can be further improved by increasing the number of the wing rings 3 within a reasonable range. Too dense wing rings 3, however, would to some extent destroy the load-bearing capacity of the wall, so that it is necessary to properly adjust the mounting position of the wing rings 3 according to the axial length of the wall 7 along the rigid sleeve 2.

Example 3

Based on the rigid waterproof pipeline for the wall body in the embodiment 1, as shown in fig. 2, the inner core 301 of the wing ring 3 is made of steel, and the bottom of the inner core 301 is welded with the outer wall of the rigid sleeve 2. The waterproof elastomer layer 302 wraps the outer portion of the inner core 301, and a low liner 304 extending outwards in an arc shape is arranged at the bottom of the waterproof elastomer layer 302. The low lining 304 encloses the weld layer 303 between the inner core 301 and the rigid sleeve 2.

Although the addition of the wing rings 3 can improve the problem of seepage and leakage caused by gaps between the wall body 7 and the rigid sleeve 2, gaps still occur between the wing rings 3 and the wall body 7 due to different thermal expansion between the wall body 7 and the inner core 301, so that the seepage and leakage can slowly and curvedly permeate along the gaps between the wall body 7 and the inner core 301. When the wing ring 3 of the embodiment is adopted, the inner core 301 plays a role of rigid support, and the waterproof elastomer layer 302, such as an SBS waterproof layer, a PP waterproof layer and the like, is filled between the inner core 301 and the wall 7, so that even if gaps are generated between the wall 7 and the inner core 301 due to different thermal expansion, the elastic waterproof elastomer layer 302 can rebound to fill the gaps in a certain range, and leakage is difficult to permeate from the gaps. Meanwhile, as the welding layer 303 is an outer convex layer with an irregular outer surface, abrasion gaps are easily generated between the welding layer 303 and the wall body 7, the welding layer 303 is wrapped by the low lining 304 of the waterproof elastomer layer 302, so that the welding layer 303 can be prevented from being in direct contact with the wall body 7, cracks generated by mutual abrasion of the welding layer 303 and the wall body 7 are reduced, the gaps are further filled, and the waterproof capability of the wing ring 3 is enhanced.

Example 4

Based on the wall rigid waterproof pipeline of the embodiment 1, as shown in fig. 3, the outer side wall of the rigid sleeve 2 is provided with steel bars 9 at positions close to the steel bars 8 in the wall. The axial direction of the steel bar 9 is vertical or approximately vertical to the axial direction of the steel bar 8 in the wall body, one end of the steel bar 9 is fixed with the outer side wall of the rigid sleeve 2, and the other end of the steel bar 9 is fixed with the steel bar 8 in the wall body.

The existing fixing between the rigid sleeve 2 and the wall body 7 mainly depends on the friction force between the wall body and the rigid sleeve 2, and once cracks are generated between the rigid sleeve 2 and the wall body 7, the cracks are gradually enlarged in the continuous friction process, so that the waterproof property is gradually reduced. By adopting the structure of the embodiment, the steel bar 9 can be used for carrying out auxiliary fixation on the rigid sleeve 2 and the steel bar 8 in the wall body, so that the movement trend between the rigid sleeve 2 and the wall body 7 is synchronous, the friction effect is obviously reduced, the expansion rate of gaps can be obviously reduced, and the effective waterproof time is prolonged.

Example 5

Based on the wall rigid waterproof pipeline of embodiment 1, as shown in fig. 4, the steel bar 9 is inserted into a through hole formed in the fixed connector 10 and welded and fixed with the fixed connector 10. The bottom surface of the fixed connector 10 is an arc surface consistent with the arc shape of the outer side wall of the rigid sleeve 2, and is welded and fixed with the outer side wall of the rigid sleeve 2.

Since the distance between the steel bars 8 and the rigid sleeve 2 in the wall is not fixed, the length of each steel bar 9 is likely to be different, and if the steel bars 9 are directly welded with the wall 7, the steel bars 9 with the corresponding lengths need to be accurately intercepted, so that the construction efficiency is reduced. The steel bar 9 and the rigid sleeve 2 are fixed by adopting the mode of the fixed connector 10, the relative length of the steel bar 9 in a certain range can be adjusted by adjusting the position of the steel bar 9 in the through hole formed in the fixed connector 10, the steel bar 9 with the corresponding length does not need to be accurately intercepted every time of fixing, and the construction efficiency is remarkably improved.

It should be noted and understood that various modifications and improvements could be made to the utility model as described in detail above without departing from the spirit and scope of the utility model as claimed. Accordingly, the scope of the claimed subject matter is not limited by any particular exemplary teachings presented.
