Description

Synthetic resin honeycomb and its manufacturing method

The present invention relates to a synthetic resin honeycomb suitable for use in underwater or aquatic structures used with water, such as floating structures and the like and a method of manufacturing the same.

In general, honeycomb structures have been applied to various structures. One of them is a honeycomb having a paper material in the middle, and a composite panel made by bonding the upper and lower plates of the inorganic fiber board to the upper and lower portions of the honeycomb.

This composite panel has a large efficiency compared to its own weight due to its high efficiency in cross section, so it is widely used as a lightweight partition wall panel of a building. Such honeycomb of paper has a fundamental problem that can not be used as a material of the water or underwater structures used with water due to the nature of the material.

On the other hand, synthetic resins such as polyethylene do not cause any chemical reaction with water, and thus are very suitable materials for use with water. However, the honeycomb prepared as a synthetic resin material such as polyethylene has not yet been manufactured and used. This is because the practical structure and production method for producing honeycomb as a synthetic resin material such as polyethylene has not been developed.

The present inventor has filed a patent for a heating pad for joining a synthetic resin sheet as a patent application No. 15939 in May 1996. The heating pad for joining the synthetic resin material is integral with the body part and the body part which are united with the heater on both sides of the rear center so as to heat and guide the molded sheet material and the adhered plate material to be transferred and the front upper surface is a curved inclined surface. While forming the lower surface is composed of a wing portion is formed to be inclined inclined so as to form a plurality of blades that the end is divided between the comb grooves that are dug at equal intervals in the longitudinal direction over the entire width direction of the upper and lower surfaces of the wing portion As having a technical configuration, it is very useful to have the effect of stably heating and welding the surfaces of the molded plate material and the adherend plate material. Applicant has conceived to use this patent invention in the production of synthetic resin honeycomb.

It is an object of the present invention to provide a synthetic resin honeycomb suitable for use in an underwater or aquatic structure used with water, such as floating structures, by using a heating pad for bonding a synthetic resin sheet and a manufacturing method thereof.

Hereinafter, the technical configuration of the present invention will be described.

The synthetic resin honeycomb 1 of the present invention has a predetermined width and the forming process of the bent end plates 10 having a shape in which the peaks 11, the connecting portion 12 and the valleys 13 are repeated, and the curved end plate 10 Alignment process of the bent end plates 10 which are arranged such that the peaks 11 and valleys 12 of the) are zigzag to each other to form a honeycomb-shaped space 14, and the peaks are aligned and contacted with each other. The 11 and the valleys 12 are manufactured by a welding process of welding the curved end plates 10 to each other by heating them with the heating heaters 20 for bonding the synthetic resin material.

Synthetic resin material honeycomb 1 of the present invention manufactured through such processes has a predetermined width and the synthetic resin material bending end plates 10 having a shape in which the peaks 11, the connection part 12, and the valleys 13 are repeated. And the welding portion 15 to the mountain portion 11 and the valley portion 13 of the synthetic resin bent end plate 10 adjacent to each other in a zigzag contact with each other to be welded to each other to form a honeycomb-shaped space (14). It consists of.

The present invention configured as described above is a synthetic resin heating heater (20) to weld the ridge 11 and the valley portion 13 of the valley end plate 10 having a predetermined width integrally weld honeycomb (1) because it is manufactured to withstand water well Synthetic resin honeycomb (1) has the effect of making it possible to produce at a relatively low cost.

The embodiment of the present invention shown in Figures 1 to 5 also has a predetermined width and forming process of the bent end plate 10 having a shape in which the peak portion 11, the connection portion 12 and the valley portion 13 is repeated, and the bending The ridge 11 and the valleys 13 of the end plates 10 are arranged in contact with each other in a zigzag manner so that the honeycomb-shaped spaces 14 are formed so as to be aligned with each other. The basic technical concept of the present invention in that it is manufactured through a welding process for welding the valley end plate 10 to each other by heating the mountain portion 11 and the valley portion 13 to be joined with a heating heater 20 for joining a synthetic resin material. Is to implement.

However, in the present embodiment, the curved end plates 10 have a predetermined width, pitch, and bent shape in the circumferential direction on the surfaces of the pair of rollers 30 engaged with each other, as shown in FIGS. 2A and 2B. The gap between the curved grooves 31 and the curved protrusions 32 formed to have a molten synthetic resin is formed while passing through the molten synthetic resin, and thus has an additional technical idea of manufacturing by cooling. .

In this embodiment, the bent groove portion 31 and the bent protrusions 32 are preferably formed at the same time a plurality of rollers 30 at a predetermined interval.

The present embodiment configured as described above has the additional effect of making the synthetic resin bent end plates 10 relatively simple.

In this way, the synthetic resin material bending end plates 10 which are laid down and molded in parallel are cooled and cooled, and after the shape of the bending end plates 10 is completed, as shown in FIG. 3, the peaks 11 of the adjacent bending end plates 10 are formed. ) And valleys 12 are aligned to abut each other to form the space portion 14 of the honeycomb, and the peaks 11 and valleys 13 are heated heaters 20 arranged between the bent end plates 10. After the melts are melted, they are pressed together and welded together to produce an overall honeycomb 1.

Here, the curved end plates 10 preferably have a trapezoidal waveform, but if necessary, may have a circular curved waveform as shown in FIG. 6. In addition, the synthetic resin material is preferably used of the polyethylene system. This is because polyethylene-based synthetic resins are considered to be the most suitable materials for synthetic resin structures used with water because of their strong chemical stability.

As described above, the present invention uses a heating heater for joining a synthetic resin sheet material to produce a synthetic resin honeycomb suitable for use in an underwater or aquatic structure used with water, such as floating structures, etc., relatively easily and inexpensively. It is very useful to have an effect.
