Referring to the drawings, the floating and insulating cover body 10 according to the present invention is bonded to the tarpaulin 20 made of a waterproof and airproof material, and the upper portion of the tarpaulin 20 along the longitudinal direction of the tarpaulin 20 It is provided with an air injection layer 40 consisting of two layers of the upper cover 41 and the lower cover 42.

The tarpaulin 20 is made of tarpaulin material to be waterproof, air defense. At this time, the waterproof cloth 20 is preferably coated with a polyolefin-based material on a polyolefin-based woven fabric. Additionally, both sides of the tarpaulin 20 may be waterproof coated to improve waterproof and airtightness. For example, it may be waterproof coated with polyvinyl chloride (PVC). Here, as described above, the floating and insulating cover body 10 formed of the tarpaulin 20 and the air injection layer 40 to be described later has a fixing hole (not shown) for floating the upper surface of the liquid material to fix the edge of the tarpaulin. Thus, a plurality may be formed and mounted.

The air injection layer 40 is composed of two layers of the upper cover 41 and the lower cover 42. At this time, the upper cover 41 and the lower cover 42 is preferably made of a cylindrical structure. That is, the cylindrical air injection layer 40 is divided into an upper part and a lower part based on the center thereof to be in close contact. The upper and lower covers 41 and 42 are continuously joined to the whole or part of the upper surface of the tarpaulin 20 along the longitudinal direction of the tarpaulin 20. Open portions 43 are formed on one side and the other side of the air injection layer 40 continuously bonded to the tarpaulin 20 to form a space layer 44 between the upper cover 41 and the lower cover 42.

On the other hand, the waterproof cloth 20 and the air injection layer 40 is bonded by an extrusion laminating method. Therefore, the floating, the insulating cover body 10 is composed of an air injection layer 40, an extrusion laminating layer 30 and a tarpaulin layer 20 consisting of an upper cover 41 and a lower cover 42. In addition, although not shown in the drawings, another waterproofing cloth may be extruded into the air injection layer 40 including the upper cover 41 and the lower cover 42 to enhance strength and durability. That is, a waterproof cloth is wrapped around the air injection layer 40.

As a result, by the structure as described above, the volume during storage is significantly reduced compared to the prior art, the floating / thermal insulation cover body 10 is transported to the site in the state of being stored floating / thermal insulation cover ('of Figure 7a and 7b) 100 ').

According to the present invention, the upper cover 41 and the lower cover 42 are made of the same material, and preferably, nylon film and polyolefin film are used.

More specifically, the upper cover 41 and the lower cover 42 are formed in a multi-layered structure by coextrusion of films of different materials, or are formed in a multi-layered structure by applying an adhesive to film layers of different materials. . That is, in the case of co-extrusion, a graftmer-based copolymer co-polymer is formed in a multilayer structure, and cyanoacrylate is formed on different materials, for example, a nylon film layer and a polyolefin film layer. It is formed into a multilayer structure by laminating using a system adhesive. Therefore, the copolymer polymer and cyanoacrylate adhesive should be understood as one adhesive layer for bonding films of different materials to each other.

As a result, the upper cover 41 and the lower cover 42 are formed of an adhesive layer formed between the nylon film layers 41a and 42a and the polyolefine film layers 41c and 42c and the film layer. It consists of a 3-layered structure of 41b and 42b. At this time, the polyolefin film layers 41c, 42c, the adhesive layers 41b, 42b, and the nylon film layer 41a from the surface where the upper cover 41 and the lower cover 42 face each other, that is, from the inner circumferential surface of the cylindrical shape. , 42a. That is, the polyolefin film layer 41c of the upper cover 41 and the polyolefin film layer 42c of the lower cover 42 should be positioned to face each other. This is because the polyolefin film layers 41c and 42c are easily bonded to each other when the upper cover 41 and the lower cover 42 are adhered to each other, and the nylon film layers 41a and 42a are surfaced. This is because it is not only excellent in wear strength than the polyolefin films 41c and 42c, but also superior in tensile strength, durability, and scratch resistance. As a result, when the impact is applied to the floating and insulating cover body 10, the durability of the floating and insulating cover body 10 having the above structure is more excellent.

On the other hand, the material used for the production of the polyolefin (polyolefine) film layer is preferably a low density polyethylene (LDPE) material of the polyolefin-based material.

Here, the thickness of the nylon film layer (41a), 42a is 10 to 70 micrometers based on the cross section, the thickness of the polyolefin film layer (41c), 42c is 20 to 60 micrometers based on the cross section, the film It is preferable that the thickness of the adhesive layers 41b and 42b which adhere | attach a layer is 10-30 micrometers based on a cross section. If the film layers 41a, 42a, 41c, 42c and the lower limit of the thickness of the adhesive layers 41b, 42b are less than the lower limit, they are not preferable due to lack of air permeability. It is not economical because it is not preferable.

First, the floating and insulating cover body 10 to which the air injection layer 40 is continuously joined along the longitudinal direction of the waterproof cloth 20 is prepared. At this time, the floating and insulating cover body 10 is stored in a predetermined length, one side and the other side of the air injection layer 40 is open.

Next, the floating and heat insulating cover body 10 is cut to an appropriate size according to the use and place. Preferably, the appropriate size of the floating and insulating cover body 10 should be understood as a size including a width and a length connected by connecting a plurality of places according to the place.

Subsequently, the cut floating / heat insulating cover body 10 is bonded so as to be sealed. That is, the opening 43 is formed on one side and the other side of the air injection layer 40. At this time, the adhesion of the opening portion 43 of the air injection layer 40 is bonded by heat fusion, ultrasonic bonding or high frequency heat compression.

Subsequently, an air injection valve 45 is provided to allow air to flow in and out of the space layer 44 formed between the upper cover 41 and the lower cover 42 by adhesion. At this time, the lower cover 42 is bonded to the waterproof cloth 20, it is preferable that the air injection valve 45 is installed on the upper cover (41). In addition, in the drawings represented in the present specification, the air injection valve 45 is schematically represented and the number thereof is also expressed as one, but the present invention is not limited thereto and is generally used as long as it has a structure capable of injecting or discharging air from the outside. Any type of air injection valve can be used, and the number can be optionally employed.

Finally, air is injected into the floating and insulating cover body 10 in which the air injection valve 45 is installed and installed at the site where the floating and insulating cover 100 is required. That is, air is injected into and installed in the floating / thermal cover 100 manufactured through the above steps.

In addition, it is apparent that a plurality of air injecting layers may be bonded to the floating and insulating cover 100 to form the floating and insulating cover connecting members 200 in which the air injection layers are connected and expanded (see FIG. 8). In this case, although the air injection layer 20 of the floating / thermal cover connector 200 is shown to be adjacent to each other, but is not limited to this, it is obvious that it can be variously bonded, such as being bonded at a predetermined interval.

On the other hand, by injecting a blowing agent into the floating and insulating cover 100 may also enjoy the effect of warming in addition to the floating effect. That is, because of the heat retention effect, it can be used for applications such as simple walls such as construction sites.
