FIG. 1 is a schematic view showing an embedded structure in a water supply pipe wall according to an embodiment of the present invention;
FIG. 2 is a schematic view showing a water supply pipe and a threading pipe according to an embodiment of the present invention.
Detailed Description
The embodiments of the present invention will be described below with reference to the accompanying drawings. Those of ordinary skill in the art will recognize that the described embodiments can be modified in various different ways, or combinations thereof, without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Furthermore, in the present description, the drawings are not to scale and like reference numerals refer to like parts.
As shown in fig. 1, the embedded structure in the water supply pipe wall of this embodiment includes a PVC (polyvinyl chloride) threading pipe 1, a PPR (polypropylene random copolymer) water supply pipe 2, a junction box 3, and a PPR elbow 6 embedded in the wall. And poured walls 6 are arranged among the formworks 5 arranged at intervals, and the embedded structures are embedded in the poured walls. PVC threading pipe 1 is the straight tube that has the lumen that link up, can specifically arrange its position in the wall body according to the position in the construction drawing. PVC threading pipe 1 vertical setting in figure 1, terminal box 3 is two for the hollow casing of rectangle that has the cavity, and terminal box 3 is connected respectively at the both ends of PVC threading pipe 1, and the cavity of terminal box 3 and the lumen intercommunication of PVC threading pipe 1, PPR elbow 6 set up in terminal box 3, and PPR elbow 6 can be 90 elbows.
The PPR water supply pipe 2 penetrates into the PVC threading pipe 1, two ends of the PPR water supply pipe penetrating out of the PVC threading pipe 1 are respectively communicated with one end of the PPR elbow 6 in the junction box, and the other end of the PPR elbow 6 penetrates out of the wall body. Or exposed outside the wall. Wherein, the connection of PPR feed pipe 2 and PPR elbow 6 can be for adopting hot melt to connect.
Through the structure that PPR feed pipe, PVC threading pipe, terminal box interconnect, save the time of later stage chiseling the wall chase again when guaranteeing the integrality of shear wall structure.
The following describes the construction process of the pre-buried structure in the water supply pipe wall.
The PPR water supply pipe 2 is connected with a PPR elbow 6, pressure testing is carried out on the PPR water supply pipe 2, the pressure can be carried out according to design drawings and test pressure required in 'inspection and acceptance standards of building water supply and drainage and heating engineering', one end is plugged, the pressure is firstly increased to 1.0Mpa of the test pressure and stabilized for 1h, the pressure drop is not more than 0.05Mpa, the pressure is reduced to 1.15 times of the working pressure after the PPR water supply pipe is qualified, namely 0.23Mpa and stabilized for 2h, the pressure drop is not more than 0.03Mpa, and meanwhile, the pressure is checked at each connection part of the pipeline, and the condition that no leakage exists is qualified is obtained.
Then penetrate PVC threading pipe 1 with PPR water supply pipe 2 in, be connected PPR water supply pipe 2's both ends with the one end of PPR elbow 6 respectively, then place PPR elbow 6 in terminal box 3 to make PPR elbow 6's the other end wear out from terminal box 3, then arrange the structure of assembling at the mounted position.
Then when the wall body reinforcing steel bars are bound, the structure is placed in the reinforcing steel bar framework on the inner side of the wall body, and the binding with the reinforcing steel bars 4 is firm according to the installation position in the drawing.
Concrete is then poured and the other end of the PPR elbow 6 is left exposed for communication with other external pipes.
Further, the PVC threading pipe 1 is a corrugated pipe.
Further, PPR elbow 6 is the bellows, can see from figure 1 that owing to adopt the bellows, and the inner chamber space through the terminal box, can be so that PPR elbow 6 has certain bending property in the terminal box, makes from this pour behind the formation wall body, PPR elbow 6 still can be when being connected with external pipeline, can have better adaptability to the installation angle of adaptation external pipeline.
Further, the PVC threading pipe 1 has a plurality of parallel pipe cavities, in which the PPR water supply pipes 2 are respectively penetrated, and the ends of the PPR water supply pipes 2 are respectively connected with different corrugated pipes in the junction box 3, and the different PPR water supply pipes 2 can be used for conveying water with different temperatures or properties, such as purified water, tap water, hot water, cold water, and warm water.
Further, for reducing the buoyancy of concrete and assaulting to lead to penetrating the drunkenness aversion of the PPR feed pipe 2 in PVC threading pipe 1 PPR feed pipe 2 wears out PVC threading pipe 1's both ends and all installs the pipe strap respectively, the external diameter of pipe strap is greater than the internal diameter of PVC threading pipe 1 to restriction PPR feed pipe 2's axial drunkenness.
In an alternative embodiment, as shown in fig. 2, an external thread is provided on the outer wall of the water supply pipe, and an internal thread matching with the external thread is provided on the inner wall of the threading pipe. The internal thread and the external thread can be a small part of area of setting in pipe one end, are only used for closing it slightly and prevent the drunkenness when pouring, for example set up external thread and internal thread respectively at the left end of feed pipe and threading pipe, for making internal thread and external thread can close soon, what can adapt to increases the feed pipe left end external diameter a bit slightly, and this can be confirmed according to the actual diameter of feed pipe and threading pipe. The water supply pipe is inserted into the threading pipe from the left end until the right end penetrates out of the right end of the threading pipe, the water supply pipe is rotated, and the external thread at the left end of the water supply pipe is screwed with the internal thread.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made to the present invention by those skilled in the art.
