Description

[Detailed description of the invention] Methods and Means for Forming Reinforced Ribbed Structures The present invention is particularly applicable to tubes, Concerning methods and means for forming reinforced ribbed structures that can also be applied to panels. In particular, the strips have a series of upright ribs on at least one side and are mutually secured. Relates to a type of horizontal body in which matching edge means are used.

This shape of a spirally wound tube is already well known, and the shape of the slip and the shape of the machine formed from such tubes. The invention is described in the inventor's patent. Plastic material with ribbed ellipse The tube-shaped tube is attractive for forming a low-cost duplex for water pipes or sewer pipes. Generate forceful methods.

One problem with such tubes is that such tubes are thermoplastic. when embedded in a ditch or subjected to high ground loads. The tube has a low elastic modulus at the point where it satisfies the bending standard value of It must have relatively high ribs and thick walls.

The purpose of the present invention is to improve the manufacturing method and the tube itself formed according to the present invention. This improvement is achieved by the reinforcing member associated with the formed tube. thus achieved. Reinforcement elements can be in the form of strips or in proportion to the selected cross-sectional shape. Consisting of a relatively stiff member, this reinforcing member resists deflection and distortion of the tubular object. Locked to or placed between lateral bodies so as to be substantially increased Or embedded in the body laterally.

by means of steel springs etc. wrapped around the walls of the tube during manufacture, or by By embedding wire spring material in the material structure associated with the tube, Of course, it is already known that tubes such as those used in vacuum lines can be reinforced, for example. It is being The purpose of the present invention is that some lateral stiffness may be necessary. However, the purpose is to make the ribs strong at least approximately in the radial direction.

A spirally wound plastic tube is placed in the classroom and backfilled with sand or gravel. When a load is applied to the top of the backfilled tube, the load Is it from a truck wheel or just a hydraulic jack in a steel plate? The load deflects the embedded test pipe, although it may be due to severely distorted) and damaged it. The failed mode deformed the top of the pipe, but the The rest of the tube was in good condition. Specifically, if the tube deforms beyond its elastic limit, Once shaped, the helical seam spring opens and the sand backfill under load immediately Inflow from the open part causes the ribbed shape to collapse laterally, creating a "domino effect". This increases the problem.

The purpose of the invention is to strengthen the joint so that the entire tube has improved properties. There are many things.

For example, by engaging the strip upright along the wall of a T-shaped rib. One of the problems with wrapping strips etc. around the body.

It is possible to achieve the desired circular shape when the surfaces of such materials are arranged radially. and the formed strip is helically bent to form a tube. 8. The present invention is that the strip can fit tightly into the ribs when Therefore, the reinforcement ribbon can withstand the load in the radial direction while the reinforcing ribbon etc. so that it is formed so that it can be corrugated in the direction or bent into a circular shape. Designed. The present invention is not limited to tubular structures, but is also applicable to It can also be applied to flannel.

The reinforcing member is designed so that the reinforcing member significantly increases the resistance to deflection (distortion) of such objects. It can be locked against the ribs or placed between the ribs. metal reinforcement member instead of using plastic resins such as epoxy or polyester. A strip of immersed m-fiber glass can be used.

Steel or other reinforcing members are used to avoid corrosion and to absorb shock. , can be enclosed in an elastic or plastic shell. The reinforcing member is Materials such as stainless steel that do not deteriorate due to exposed parts or conditions It may be made from
