Description

Corrugated honeycomb multilayer body {a duplex wall for reinforce material intervals formation of inserted groove}

The present invention relates to a corrugated honeycomb multilayer body in which an insertion groove is provided between a partition wall protruding between both covers and at least one partition wall having a closed space therein. More specifically, the interior of the multilayer body protrudes between both covers. The partition wall improves the sealing function of at least one airtight space and the Hana comcell outside the partition wall, blocks external noise and impact, etc., and extends vertically to a part of the reinforcing member of some layers of the reinforcing member stacked in multiple layers. Or a corrugated honeycomb multilayer body in which an insertion groove is formed between a sealed multi-stage reinforcing member that can be easily and easily connected and installed inside the multilayer body by forming an insertion groove through the insertion groove. It is about.

In general, in order to block air through which sound is transmitted, a reinforcing member having a closed honeycomb structure is constructed and installed inside and outside the furniture or door or building panel. And Honeycomb with a plurality of spaces formed inside the partition wall, patents of Honeycomb B cell 100622609,101154357,10027606, Practical use of tin cans with partial protrusion and upper blockage with a C press, partial hexagonal press from both covers to the inside of each other It protrudes or partially hexagonally protrudes from the injection furnace and protrudes between the ondol honeycomb and both covers of the ondol pipe provided between the honeycombs, and partially hexagonally protrudes from both covers to the inside by pressing or partially hexagonally protrudes from the injection furnace. The ondol honeycomb provided with the ondol pipe between the honeycomb has a problem that it is impossible to confine the space, and it is a schematic perspective view of the patent 100970673 for the D connection, and FIGS. 6 and 7 are honeycomb cells, 200371059.

101219077,1011543457,100272606,100535299,200393594,200351045 and the above honeycomb board patents 100411246,100411246,10112267,202017024,200476188,

200314034,200330933,1011222267 consists of a single layer and a structure in which a partition wall of the daytime with paper or aluminum or metal or resin or composition is formed between the honeycomb covers, and is installed on exterior panels of buildings, roads, furniture, and doors.

However, these two covers are partially hexagonally protruded from each other by pressing into each other, or partially hexagonally protruded by an injection furnace, and protruded between the ondol honeycomb provided with the ondol pipe and the both covers between the honeycombs, and have at least one closed space within the In the honeycomb having a wall that is a partition wall of the gate and having at least one hexagonal cell formed outside the wall, at least two or more honeycombs are multilayered, and an external wire or pipe is inserted into some layers of the multilayer. It is to provide a multilayer body provided with one or more insertion grooves.

Honeycomb is a disadvantage in that when external noise and impact are transmitted to the multilayer body of furniture or door, the noise and impact cannot be sufficiently absorbed in the space inside the bulkhead of the reinforcing member installed inside the multilayer with only one layer. There is this. Therefore

Fig. 5A is a single-layer honeycomb with a large number of hexagonal-shaped partition walls of the valley gate used in Japanese Practical Use Hei 07017538 and Practical 200219811 and a plurality of spaces formed inside the partition walls, wherein only holes are added to the practical 200219811, and the reinforcing member A number of small spaces are formed on the floor and the hexagonal partition wall. The plurality of partition walls 11 protruding from the bottom to block external sound and impact on the inside, a hexagonal space portion 12 outside the partition 11, and a plurality of partition walls 11 formed inside the partition wall 11 The small space 13 is made to properly absorb external noise and vibration due to impact.

However, as for the purpose of the application, the portion of the hexagonal-shaped partition for inserting external wires or pipes in a certain length direction has only the upper and lower covers, and this means that the upper and lower sides are hexagonal-shaped partitions. There is a problem that there is no sealing, that is, there is a problem of tearing according to the width. At this time, even if the material of the cover is different, there is a problem that there is no partition wall having a hexagonal shape on the upper and lower sides, that is, there is no sealing.

Accordingly, in order to improve the above problem, a plurality of hexagonal-shaped normal partitions protruding inside the upper and lower covers of the 10200935874 honeycomb of FIG. 5 of the applicant are formed, and a triangular or square or at least one partition inside the partition wall And a honeycomb having at least one partition and a closed space in the interior of the hexagonal and partition wall having at least one space, the honeycomb is stacked at least one or more, and at least one or more honeycombs are provided on one or both sides, , The structure of forming an insertion groove penetrating in a horizontal or vertical direction for inserting an external wire or pipe into at least one or more predetermined portions of the honeycomb on one side is the multilayer body stacked in multiple layers, the inner side of the multilayer body 100 By absorbing external sound and shock and inserting external wires or pipes into the honeycomb of some layers, at least one or more layers of the enclosed space are maintained, which is impossible in the past.

However, there is a problem of penetrating adjacent portions of the multilayer body in continuous contact with each other.

In addition, the H-shaped material fitting has a problem of protruding the H-shaped material.
