Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a protective film for protecting at least a locking portion of a joint member for connecting and waterproofing adjacent buildings until construction.
[0002]
[Prior art]
As shown in FIGS. 9 and 10, there is a gap between building units 12 and 12 of a building, for example, a prefab house, and this portion is connected by a pair of joint members 4, 4 ', 4a and 4a'. Generally it is waterproofed. That is, the joint members 4, 4 ′, 4 a, 4 a ′ are sandwiched between the units 12, 12, for example, the outer wall 5 or the column 6, and the locking portions 9, 9 ′, 9 a, 9 a on the tip side are held. 'Are connected to each other by fastening or bonding.
The joint members 4 and 4 ′ shown in FIG. 9 are provided with fastener-type locking portions 9 and 9 ′, and the joint members 4a and 4a ′ shown in FIG. 10 are provided with adhesive-type locking portions 9a and 9a ′. There are various shapes of the locking portions, and these locking portions 9, 9 ', 9a, 9a' are disposed so as to protrude from the end edges of the units 12, 12.
[0003]
[Problems to be solved by the invention]
As described above, the joint members 4, 4 ′, 4 a, 4 a ′ are in the state of protruding from the unit 12 and are subjected to each process such as line painting, transportation, installation, etc. Have problems such as damage during painting, transportation, installation and other processes. Further, since the units 12, 12 and the like are painted, the paint adheres to the engaging portions 9, 9 ', 9a, 9a' of the joint members 4, 4 ', 4a, 4a', and the fastener member. This prevents the fastener-type locking portions 9 and 9 'from being used by preventing the sliding of the adhesive, and the adhesive-type locking portions 9a and 9a' are contaminated to reduce the adhesive force of the adhesive layer. There is an inconvenience that the engaging portions 9a and 9a 'are not usable.
In particular, in the case of the fastener-type joint members 4 and 4 ′ as shown in FIG. 9, the left and right joint members 4 and 4 ′ may be different from each other. It was made to be able to distinguish. However, depending on the material of the joint members 4 and 4 ′, there are those that change in quality due to the paint and those that do not easily adhere to the color, color fading easily occurs, and there is a problem that the distinction is unclear.
[0004]
The present invention has been invented in view of the above circumstances, the joint member is reliably protected, the waterproof effect is not lowered, the right and left can be distinguished, and the joint member is formed at a relatively low cost and is easy to handle. It aims at providing the protective film of the waterproof joint member of a good building.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the protective film of the present invention is a protective film for covering and protecting a joint member connecting adjacent buildings as claimed in claim 1, wherein the protective film Is composed of a thin film film that can cover at least both front and back sides of the joint member and adhesive portions provided at both ends of the film, and the proximal end side of the joint member is formed by the adhesive portions at both ends. It is characterized in that it can be held freely.
A protective film according to claim 2 is the protective film according to claim 1, which is a protective film for protecting respective joint members of adjacent buildings having locking portions to be engaged with each other. The film is characterized by being made of different colors that can be separated.
The protective film according to claim 3 is the protective film according to claim 1 or 2, wherein the protective film is composed of a resin film and a single-sided adhesive tape that protrudes and sticks to both edges. And
The protective film according to claim 4 is the protective film according to any one of claims 1 to 3, wherein the single-sided adhesive tape is obtained by laminating an adhesive layer on a polyethylene terephthalate film. .
[0006]
Since the joint member is covered with the protective film until the start of construction, the joint member is prevented from being damaged, and the paint is not attached at the time of painting. Further, the protective film can be colored in different colors, and the male and female of the fastener-type joint member can be easily distinguished. In addition, a protective film can be easily created simply by sticking a single-sided adhesive tape to the edge of the resin fill so that it can be easily applied to small lot products. Further, if the double-sided adhesive tape is made by laminating an adhesive layer on a polyethylene terephthalate film, the protective film is very easy to handle due to the rigidity of the polyethylene terephthalate film.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the protective film of the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1 and FIG. 2, the protective film 1 of the present invention comprises a sheet-like member that completely covers the joint member, a thin-film resin film 2 that can be bent in an arc shape, and an adhesive portion provided on both edges of the film. 3.
In the present embodiment, the resin film 2 is an inexpensive poly film such as polyethylene. On the other hand, the joint part 4 (4 ') covered with the protective film 1 comprises a sandwiching part 7 that is sandwiched and fixed between the outer wall 5 and the pillar 6 of the building and a projecting piece part 8 projecting therefrom. A locking portion 9 (9 ′) is formed at the tip of the piece 8.
[0008]
The locking portion 9 (9 ') has various shapes as shown in FIGS. 9 and 10, but in FIGS. 1 and 2, the fastener-type locking portion 9 (shown in FIG. 9) ( 9 '), and FIG. 3 shows the adhesive-type locking portion 9a (9a') shown in FIG. In the present embodiment, the entire joint member is covered. However, if at least only the locking portion can be covered, the minimum protective effect can be obtained.
[0009]
Specifically, HDPE (high pressure polyethylene) having a thickness of about 10 μm is used as the resin film 2 of the protective film 1. This high pressure polyethylene is inexpensive and is translucent and blue. Thus, a translucent and blue film can be used as they are to easily form a different color protective film. Of course, arbitrary coloring is also possible. Moreover, as the adhesive part 3, an acrylic adhesive is generally used.
The adhesive part 3 is preferably configured as a single-sided adhesive tape that protrudes and sticks to both edges of the resin film 2. According to the use of such a single-sided adhesive tape, the adhesive portion 3 can be easily provided on the resin film 2 of any size by sticking to the edge portion, and also for the production of small lots. It can be easily handled.
In this case, if the single-sided adhesive tape is made of a polyethylene terephthalate film and an adhesive layer is laminated, the single-sided adhesive tape can be given rigidity by the polyethylene terephthalate film, and a thin and thin protective film can be used. The attaching operation can be easily performed.
Since the adhesive layer 3 has adhesive residue on the adherend when peeled off, a non-woven fabric layer may be provided on the adhesive layer 3 or the cross-linking density of the adhesive layer 3 itself may be increased.
[0010]
As shown in FIGS. 1 to 3, by covering the joint members 4 and 4a with the protective film 1 of the present invention, the joint members 4 and 4a are prevented from coming into direct contact with other members, and damage is avoided. . Even if an external force due to a collision or the like is applied to the protective film 1 from the outside, the protective film 1 and the joint members 4 and 4a can move relative to each other except the adhesive portion 3. As a result, the joint member 4 or 4a is prevented from being damaged by an external force.
[0011]
Further, the left and right can be easily distinguished by coloring the protective film 1 with different colors. Further, the protective film 1 prevents adhesion of paint to the joint portions 4 and 4a, color fading, and the like in the intermediate process. In addition, what is necessary is just to remove the protective film 1 at the time of construction at the time of the connection of a building, and to connect the joint members 9, 9 'and 9a, 9a' to each other in the state shown in FIGS.
[0012]
Next, how to make the relatively wide protective film 1 will be described with reference to FIG.
First, the film 2 is cut into a desired width dimension. Next, the adhesive portions 3 are formed on both edges. In the present embodiment, a single-sided adhesive tape 3 ′ having a thickness of about 100 μm and a width dimension of about 10 mm is used as the adhesive portion 3. About one half of the single-sided adhesive tape 3 'is adhered to the film 2, and the remaining half is used as an adhesive surface.
As shown in FIG. 5, this protective film 1 is bonded and fixed to a joint member by an adhesive portion 3 formed by a single-sided adhesive tape 3 ', and the adhesive material 3 is substantially present on the surface of the film 2. Without making it, the adhesion part 3 is formed in the both sides of the film 2, and it becomes possible to earn the effective area of a film.
[0013]
6 and 7 show an example of how to make a large amount of the protective film 1a having a relatively narrow width of the film 2. FIG. That is, as shown in FIG. 6, a wide film 2a is prepared, and the adhesive 10 is streaked on the film 2a at an appropriate interval. Next, as shown in FIG. 6, the film 2a is cut as shown by a one-dot chain line with an appropriate dimension. Thereby, the comparatively small piece protective film 1a shown in FIG. 7 is formed. That is, the central film surface 11 corresponds to the film 2, and the adhesive 10 on both edges corresponds to the adhesive portion 3. As described above, the small protective film 1a can be efficiently manufactured.
[0014]
As described above, the protective film 1 is generally attached and fixed to the joint members 4, 4 ′, 4 a, 4 a ′ using the adhesive portions 3, 3, but the joint members 4, 4 ′, Since the joint members 4, 4 ′, 4 a, 4 a ′ may move when the projecting dimensions of 4 a, 4 a ′ are long, to prevent this movement, as shown in FIG. Only one side is removed from the joint members 4, 4 ′, 4 a, 4 a ′, and the removed adhesive portion 3 is fixed to the outer wall 5 of the unit 12, for example. Thereby, the movement of the joint part 4 can be stopped.
[0015]
In the above description, the illustrated joints 4, 4 ′, 4 a, 4 a ′ are used, but of course, they are not limited to these shapes.
[0016]
