Description

Elbow structure

The invention relates to the construction of a pipe body, in particular to a pipe structure.

The existing building hydropower project is a pipeline in which a lead wire or a water pipe is placed inside a wall of a steel-frame structure building, and the pipe is formed by connecting a plastic pipe to an elbow, and the wall surface of the steel-frame structure building It is a structure in which the wall of the electric wire or the pipe of the water pipe is set and then grouted at the position of the wall to form a wall surface.

Although the above-mentioned plastic pipe is connected to the elbow, the pipe or the pipe of the electric wire can be arranged at a position where the steel structure is intended to form a wall surface, but the angle of the existing elbow is only 45 degrees and 90 degrees. Degree of joint, the fixed angle limits the flexibility of the product construction. When it is necessary to set the pipe with a turning angle of 50 degrees or 85 degrees during construction, it is difficult to carry out the construction to align the joints at both ends of the pipe. In addition, when When the pipeline of the plastic rigid pipe is completed, when the wall surface of the steel structure building is grouted, the pipeline is also prone to gaps or cracks due to vibration or extrusion in the grouting process, and the pipeline is blocked or leaking. Caused by the trouble of wire threading or water pipe construction.

In order to solve the shortcomings and limitations of the existing fixed pipe elbow, this The main purpose of the new type is to propose a structure of a hose, which is internally reinforced with elasticity and supporting force, so that the pipeline is easy to set up and the structure is not easily broken.

Preferably, the hose of the present invention is a polyvinyl chloride hose, and the inner peripheral surface and the outer peripheral surface are smooth surfaces.

Further, the head of the present invention is a circular tubular joint having a diameter larger than a diameter of an outer circumferential surface of the hose, and a diameter of an inner circumferential surface of the joint is equal to a diameter of an outer circumferential surface of the hose.

Further, the head of the present invention is a water pipe head, and the water pipe head is provided with a pipe portion having a diameter larger than the hose, and one end of the pipe portion is coupled to the hose, and the other end of the pipe portion is at the edge of the other end of the pipe portion. An annular disk portion is formed to extend around, and a plurality of perforations are formed in the disk portion.

Further, the head of the present invention is a circular tubular electric tube head, and the outer peripheral surface of the electric tube head is convex toward the periphery on a side close to the hose. A hexagonal ring is formed, and a threaded portion is formed on the outer peripheral surface of the electric tube head away from the other side of the hose.

Further, the head of the present invention is a junction box head, and the connection The wire box head is provided with a tube portion, one end of the tube portion is connected to the hose, and a plurality of equally spaced circumferential grooves are opened downward at the end surface of the other end portion of the tube portion, and the end faces at the other end of the tube portion are respectively directed toward A plurality of surrounding and equally spaced hooks are projected on the upper surface.

When the present invention is used, the hose is placed in a steel structure or a The structure of the wall of the building, and the role of the head to connect, connect the wire, water pipe or junction box, because the structure of the hose is suitable for bending, with the compression spring embedded in the hose to support Force and elasticity, therefore, when constructing the wire or water pipe in the wall of the bone structure building, the hose can be easily bent, so that the hose can be bent at any angle at the beam or the steel bar so as to The quasi-joint and the hose structure have no gaps. Therefore, when the wall is grouted, it will not be affected by vibration and will not crack and leak. It has good construction, easy drainage and is not easy to be damaged in use.

In order to understand the technical features and practical effects of the present invention in detail, and in accordance with the contents of the specification, the following further describes the preferred embodiment as shown in the following figure: The present invention provides a curved pipe structure, such as The first preferred embodiment shown in FIGS. 1 to 4 includes: a hose 10 which is a circular strip of PVC (polyvinyl chloride) and which can be flexed to a U shape, S with an external force. In the shape of the shape, an inner peripheral surface 11 surrounding the inner circumference of the hose 10 and an outer peripheral surface 12 surrounding the outer periphery of the hose 10 are formed on the inner side surface and the outer side surface of the hose 10, respectively, and the inner peripheral surface 11 is smoothed. The outer peripheral surface 12 is also a smooth surface.

a compression spring 20 which is a spring of the same length as the length of the hose 10, the diameter of the hose 10 being between the diameter of the inner circumferential surface 11 of the hose 10 and the diameter of the outer peripheral surface 12, The compression spring 20 extends in the same direction as the extending direction of the hose 10 and is concentrically fitted between the inner circumferential surface 11 and the outer circumferential surface 12 of the hose 10.
