Problems solved by technology

[0004] The existing installation methods of plastic water pipes are all on-site fusion welding. Due to the large amount of dust and sand on the installation site and the large difference in the proficiency of the installation workers in welding technology, it is difficult to guarantee the quality of fusion welding. If the heating time is too long and the temperature is too high, there will be welding shrinkage rings in the pipe at the welding place. Severe shrinkage rings will even block the pipeline. The welding shrinkage ring is easy to hide dirt and breed algae and bacteria, which is an important reason why the tap water or drinking water reaching the end of the hygienic waterworks is unqualified

Embodiment 1

[0017] Example 1: as figure 1 As shown in the figure, the two joints respectively adopt the inner wire interface and the fusion welding joint, which are welded into a whole by an inner wire elbow 2, a straight pipe section 1 and a fusion welding elbow 3, and there is no obvious fusion welding shrinkage ring in the pipe. A wire plug 5 is installed in the inner wire interface, and a plastic cover 4 is covered on the interface of the fusion welding elbow.

Embodiment 2

[0018] Example 2: as figure 2 As shown in the figure, the two joints respectively adopt the outer wire interface and the fusion welding joint, which are welded together by an outer wire elbow 6, a straight pipe section 1 and a fusion welding elbow 3, and there is no obvious fusion welding shrinkage ring in the pipe. The outer wire interface is covered with a stuffy cover 7, and the interface of the welding elbow is covered with a plastic cover 4.

Embodiment 3

[0019] Example 3: as image 3 As shown, the two joints use outer wire interfaces, which are welded together by two outer wire elbows 6 and a straight pipe section 1. There is no obvious welding shrinkage ring in the pipe, and the outer wire interface is covered with a stuffy cover 7 and Comes with outer wire decorative cover.

Abstract

The invention relates to a design and installation method of cold and hot water supply lines used in kitchens and washrooms, which comprises the following steps: when building a brick wall or pouring a concrete wall, a die plate is used for reserving a groove of a pre-buried water pipe assembly on the wall; a water main is laid and fixed along the wall edge, the ground is poured, and the ground accessing to the groove is not poured at the time; after the solidification of the pouring, an external interface at the upper end of the pre-buried water pipe assembly is calibrated, positioned, initially fixed, then treated with fusion welding and communicated with the underground main; and after passing the press test, the ground around the interface is back poured, and the pre-buried water pipeassembly is concealed. The pre-buried water pipe assembly comprises a straight pipe section and two interfaces arranged at the two ends of the straight pipe section, wherein, the two interfaces can adopt interfaces with internal thread or joints with external thread and are correspondingly provided with pipe plugs or blank caps, and one of the two interfaces can also adopt a fusion welding interface. The method is convenient for decoration, and avoids damages to the wall when in decoration and unnecessary waste.

Description

technical field [0001] The invention relates to a design and installation method for hot and cold water supply pipelines in kitchens and toilets. Background technique [0002] The water supply pipelines of kitchens and bathrooms in existing commercial buildings are generally exposed. The exposed water pipes not only affect the decoration of kitchens and bathrooms, but also affect the placement of their facilities. Therefore, after the commercial houses are turned over, almost 100% of the owners will be exposed. The water pipes were removed, and the dark pipes were re-grooved on the wall. Some decorators also broke the steel bars and damaged the wire casings and wires when grooving. The above general phenomenon is a huge waste of limited resources and labor, and it goes against the basic national policy of building a conservation-minded society. [0003] Although there are constantly requirements for fine decoration of kitchens and bathrooms in commercial houses, the existin...
