[0002] In the building water supply and drainage system, the connection and fixation of the pipeline are the key link to ensure the normal operation of the whole system. The traditional water supply and drainage pipeline connection mode usually adopts the clamp connection, however, the existing clamp connection technology has some obvious problems.
[0003] At present, the conventional clamp and the pipeline connection are connected in the vertical state, this connection mode is easy to cause the loosening between the pipeline and the clamp due to the influence of the water flow impact, temperature change, building settlement and various factors in the long-term use process. Further, it causes the water leakage problem, which brings many inconveniences to the daily life and business activities of residents. UTILITY MODEL CONTENTS
[0004] In view of the deficiencies of the prior art, the utility model provides a building water supply and drainage pipeline.
[0005] In order to realize the above-mentioned purpose, the technical scheme of the utility model is as follows:
[0006] A building water supply and drainage pipeline, including the pipeline body and the semicircle clamp for connecting two pipeline bodies;
[0007] The both ends of the pipeline body are outwardly expanded opening type structures;
[0008] The inner wall of the semicircle clamp is a structure with thick ends and a concave middle, and the angle of the semicircle clamp concave matches the angle of the pipeline body expansion opening;
[0009] The T-shaped block is fixed in the middle of the inner wall of the semicircle clamp, and the space for clamping the pipeline body expansion opening is formed between the semicircle clamp and the T-shaped block;
[0010] When the pipeline body is clamped between the semicircle clamp and the T-shaped block, the fitting surface of the semicircle clamp and the pipeline body forms an included angle with the water flow direction.
[0011] Preferably, the angle range of the pipeline body expansion opening is 5°-10°, and the angle range is configured to facilitate the semicircle clamp to clamp the adjacent two pipeline bodies.
[0012] Preferably, the side of the T-shaped block close to the concave inner wall of the semicircle clamp is provided with a bevel, the inclination angle of the bevel is the same as the concave angle of the inner wall of the semicircle clamp, and the bevel is configured to fit the inner side wall of the pipeline body expansion opening.
[0013] Preferably, the T-shaped block is provided with a chamfer at the end close to the recessed side of the semicircular clamp, and the chamfer is configured to facilitate the insertion of the pipe body into the space between the semicircular clamp and the T-shaped block.
[0014] Preferably, the recess of the semicircular clamp is provided with a sealing gasket, and the sealing gasket is tightly attached to the outer surface of the pipe body.
[0015] Preferably, the semicircular clamp is fixed with an edge lug at each corner to facilitate the insertion of a screw.

[0017] 1. The pipe body is clamped in the gap between the clamp and the T-shaped block, and the two clamps are used to fix the adjacent two pipe bodies together. The inwardly recessed structure in the inner wall of the clamp clamps the expanded opening of the pipe body, so that the direction of the acting force of the clamp on the pipe body is not perpendicular to the length direction of the pipe body, and the separation of the pipe body and the clamp is limited, thereby improving the fixing effect between the adjacent two pipe bodies.
