Description

Technology Field

[0001] The disclosed content relates to a concrete conveying hose equipped with a reinforcing structure that enables the stable conveyance of concrete by providing a reinforcing structure between an inner hose and an outer hose. Background Technology

[0003] Unless otherwise indicated in this specification, the contents described in this section are not prior art for the claims of this application, and are not to be recognized as prior art simply because they are included in this section.

[0005] Generally, when pouring concrete to construct concrete structures, mixed concrete transported via ready-mix concrete is poured on-site using a pump truck. This pump truck is equipment that pumps concrete and transports it to a construction site at a high location. It consists of a cylinder section that pushes the concrete, a steel pipe that transports concrete in a pressurized slurry state, and a hose connected to the tip of the steel pipe to facilitate the discharge of concrete to the pouring site.

[0006] However, while steel pipes have relatively high rigidity and are therefore less likely to be damaged or deformed by the transported concrete, hoses have relatively low rigidity, so there is a possibility of damage or deformation if high-pressure concrete is continuously transported.

[0007] There was a problem in that if deformation or damage occurred in the hose while transporting concrete, it would be difficult to accurately transport the concrete to the pouring site, construction could be delayed, and additional maintenance costs could be incurred. Prior art literature

[0010] The present invention provides a concrete conveying hose having a double structure with an inner hose and an outer hose, and a reinforced structure with an additional reinforcing member to prevent stretching, deformation, or damage between the inner hose and the outer hose during concrete conveying. means of solving the problem

[0012] The disclosed embodiment describes a concrete conveying hose equipped with a reinforcing structure, characterized by comprising: an inner hose member positioned on the inner side of the hose, having both ends open and a hollow interior; a reinforcing member provided on the outer circumference of the inner hose member; and an outer hose member fixedly positioned in close contact with the outer circumference of the inner hose member provided with the reinforcing member, having both ends open and a hollow interior.

[0013] In the disclosed content, the reinforcing member is defined as a braided yarn or wire formed into a mesh structure. Effects of the invention

[0015] According to the concrete conveying hose equipped with the reinforcing structure described above, it is composed of a double structure of an inner hose member and an outer hose member, and a reinforcing member formed of a mesh structure braided yarn or wire is provided between them. As a result, deformation and damage to the inner hose member and the outer hose member can be prevented during concrete conveying, allowing concrete to be accurately conveyed to the pouring site. This enables rapid construction and offers the excellent advantage of easy maintenance. Brief explanation of the drawing

[0017] FIG. 1 is a perspective view of a concrete transfer hose equipped with a reinforcing structure according to one embodiment of the disclosed content. FIGS. 2 and FIGS. 3 are reference drawings illustrating the manufacturing state of a concrete conveying hose equipped with a reinforcing structure according to one embodiment of the disclosed content. Specific details for implementing the invention

[0018] The advantages and features of the disclosed content and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the disclosed content is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to ensure that the disclosure of the disclosed content is complete and to fully inform those skilled in the art of the scope of the disclosed content, and the disclosed content is defined only by the scope of the claims. Throughout the specification, the same reference numerals refer to the same components.

[0020] In describing the embodiments of the disclosed content, if it is determined that a detailed description of known functions or configurations could unnecessarily obscure the essence of the disclosed content, such detailed description will be omitted. Furthermore, the terms described below are defined considering the functions in the embodiments of the disclosed content, and these may vary depending on the operator's intent or convention. Therefore, their definitions should be based on the content throughout this specification.

[0022] FIGS. 1 to 3 illustrate one embodiment according to the disclosed content. FIG. 1 is a perspective view, and FIGS. 2 and 3 are reference drawings.

[0025] Hereinafter, the constituent members of a concrete transfer hose (1) equipped with a reinforcing structure according to a preferred embodiment of the disclosed contents with reference to FIGS. 1 to 3 and their operational relationships will be described in detail.

[0027] First, an internal hose member (10) is provided. This internal hose member (10) substantially functions as the entire hose and is located on the inside of the hose, with both ends open and the interior formed hollow.

[0028] This internal hose member (10) is extruded in the shape of a rod with a cross section that is rhomboidal, and may optionally have a core material (11) inside as shown in FIG. 2, and after extrusion, the hypotenuses of the rhomboids come into contact with each other and are wound in a spiral shape.

[0029] And the inner hose member (10) is formed by extruding the raw material PVC and winding it into a spiral shape. Since the extrusion and winding methods are already known technologies, further detailed descriptions will be omitted for the sake of brevity of the specification.

[0030] In addition, the specifications such as the thickness, inner diameter, and outer diameter of the aforementioned inner hose member (10) can be varied in many ways depending on the purpose of use and the pump car to which it is installed.

[0032] A reinforcing member (20) is provided on the outer circumference of the aforementioned inner hose member (10). This reinforcing member (20) serves to prevent deformation such as stretching or damage such as tearing when concrete is transported into the hose at high pressure.

[0033] These reinforcing members (20) are formed as braided yarns or wires with a mesh structure, and the size and shape of the mesh structure can be varied.

[0035] An outer hose member (30) is fixedly positioned in close contact on an inner hose member (10) equipped with the aforementioned reinforcing member (20). This outer hose member (30) protects the aforementioned reinforcing member (20) and simultaneously serves to finish the outside of the hose.

[0036] The external hose member (30), like the internal hose member (10) described above, has both ends open and the interior is formed hollow. The external hose member (30) described above is formed by extruding the raw material PVC and winding it into a spiral shape. It is extruded in a strip shape with a relatively thin cross-sectional thickness compared to the internal hose member (10), and after extrusion, it is wound into a spiral shape on the internal hose member (10) equipped with a reinforcing member (20).

[0038] According to the concrete conveying hose equipped with the reinforcing structure described above, it is composed of a double structure of an inner hose member and an outer hose member, and a reinforcing member formed of a mesh structure braided yarn or wire is provided between them. Consequently, deformation and damage to the inner hose member and the outer hose member during concrete conveying can be prevented, allowing concrete to be accurately conveyed to the pouring site. This enables rapid construction and facilitates easy maintenance.

[0040] The disclosed content is merely illustrative and can be modified and implemented in various ways by a person skilled in the art without departing from the gist of the claim claimed in the patent claims; therefore, the scope of protection of the disclosed content is not limited to the specific embodiments described above.
