Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention has a shape along a corner portion where a plurality of surfaces of a waterproof base of a building are butted against each other, and the waterproof sheet installed on the surface of the waterproof base is attached to the corner. For more details on waterproofing materials made of synthetic resin for joining together, for example, a plurality of surfaces of a waterproofing base, such as a floor surface or wall surface of a mortar on the roof of a building, covered with a waterproofing sheet of vinyl chloride resin, etc. The present invention relates to a waterproof accessory that is used to enhance waterproofness by being fitted with a corner at the corners where the two abut each other.

[0002]

[Prior art]

 Conventionally, such a waterproof accessory has been formed to have a uniform thickness as a whole.

[0003]

[Problems to be solved by the device]

 In general, such a waterproofing material is attached to the waterproof sheet first along the corners where the multiple surfaces of the building's waterproofing base are abutted, by heat fusion or chemical welding. After joining one surface of the joining surface portion to the waterproof sheet, the unbonded joining surface portion is sequentially joined to the joined surface portion of the corresponding waterproof sheet for use.

In the case of joining by fusion, for example, if there are three joining surface portions, first, the first joining surface portion and the joined surface portion of the waterproof sheet are heated by a heating device such as a hot air generator. And fuse them together. The fusion is performed by pressing the joint surface portion in the overheated and softened state to adhere and solidify it. Next, while bending the second joint surface portion, the surface where the second joint surface portion and the surface to be joined are brought into contact with each other is heated by a heating device such as a hot air generator to be fused. At this time, in order to heat the surfaces to be joined together, the second joining surface portion is bent toward the front, and the second joining surface portion in the bent state is heated and then pressed against the second joined surface portion to be fused. Not. Also, the third joint surface portion is fused by performing the same operation as the second joint surface portion.

When the joint surface portion is pressed to bond it, a large pressure is applied to the pressing portion, and the pressed portion of the waterproofing component is crushed to become thin, and in severe cases, there is a hole for waterproofing. There was a risk of damaging. In particular, waterproof parts need to have their corners pressed down in order to improve the adhesion with the waterproof sheet that is installed on the waterproof base, and the stress to be pressed is concentrated at the corners of the waterproof part. However, there was a high risk that the corners would be damaged and the waterproofness would be impaired.

Therefore, it is conceivable to form the entire waterproofing component into a thick wall to increase the overall strength. However, if the entire bonding surface part becomes thicker, the flexibility decreases and the surface to be bonded becomes uneven. If there is such a case, it becomes difficult for the joint surface portion to follow the joint surface portion. Further, at this time, it becomes difficult to bend, and there is a drawback that workability is deteriorated especially at low temperature.

These drawbacks also occur when welding is performed using a chemical.

[0008] Therefore, an object of the present invention is to provide a waterproofing member capable of performing a joining work by preventing the adhesion between the joining surface portion and the joined surface portion from being deteriorated and preventing the deterioration of the waterproofness between them due to damage or the like. There is something to do.

[0009]

[Means for Solving the Problems]

 The characteristic configuration of the present invention for achieving this object is that the joining surface portions are abutted to each other rather than a plurality of joining surface portions that can be individually joined to a waterproof sheet provided on each of a plurality of surfaces of a waterproof base. The corners are formed to be thick, and even if they are formed so that the thickness gradually increases from the joint surface to the corners, or the corners are harder than the joint surface. A reinforcing portion made of the above material may be provided, and the effects obtained from the reinforcing portion are as follows.

[0010]

[Action]

 In other words, according to the waterproof accessory of the present invention, when joining to the joined surface portion of the waterproof sheet, since the corner portion is formed thicker than the joining surface portion, it is reinforced against the pressing force at the time of joining. Therefore, even if the corners are strongly pressed at the time of joining, the risk of thinning or perforation that would impair waterproofness is reduced.

Further, since the end edge portion of the joint surface portion is thinner than the corner portion, it has high flexibility, and it is easy to follow the joint surface portion of the waterproof sheet.

Further, if the thickness is gradually increased from the joint surface portion to the corner portion, the strength is increased as it is closer to the corner portion, the flexibility is better at the edge portion, and the adhesive is spread over a wide range. It is possible to realize a structure that has good properties and can easily follow the surface to be joined of the waterproof sheet. Further, if the corner portion is provided with a reinforcing portion made of a material harder than the joint surface portion, the corner portion reinforcing structure can be realized by simply modifying the conventional waterproof material.

[0013]

[Effect of device]

 Therefore, the risk that the corners are strongly pressed at the time of joining to impair the waterproofness is greatly reduced, and it is now possible to provide a waterproof accessory that can be easily and reliably erected. .

【Example】

 In the following, the waterproof accessory of the present invention is used to form a corner C1 in which a floor surface 2a, a first wall surface 3a, and a second wall surface 3b are abutted against each other in a corner portion 1 of a rooftop of a building (Fig. 4) is used as a waterproof base for waterproofing by attaching it to the surface D to be joined of the waterproof sheet 4 which is already installed as a waterproof base, with reference to the drawings.

As shown in FIG. 4, the roof of the building is a handrail wall composed of a plurality of wall surfaces facing each other, and has a structure surrounding the floor surface 2a of the mortar. Assuming that the first wall surface 3a is the first wall surface 3b and the north-south wall surface is the second wall surface 3b, a vinyl chloride waterproof sheet 4 is spread over the entire floor surface 2a, the first and second wall surfaces 3a, 3b. It is a cottage and is waterproof.

As shown in FIGS. 1, 2 and 3a, the waterproof accessory of the present invention is a waterproof sheet 4 provided on each of the floor surface 2a, the first wall surface 3a and the second wall surface 3b of the waterproof base. To the corners B where the adjacent joint surfaces are in contact with each other, from the first, second, third, joint surfaces A1, A2, and A3, which are freely connectable to each other, with vinyl chloride resin. It is integrally molded.

When this waterproof accessory is attached, first, as shown in FIG. 3a, the waterproof sheet 4 made of vinyl chloride resin is used as a waterproof base, and the floor surface 2a, the first wall surface 3a, and the second wall surface 3b. Set up each one. Next, a portion corresponding to the corner portion 1 of the waterproof base of the waterproof sheet 4 is set as a joined surface portion D, and the floor surface portion D1 of the joined surface portion D is heated with hot air by the hot air generating device 5 and, at the same time, the waterproof role is obtained. The first joint surface portion A1 of the article is heated, both are made to be in a semi-melted softened state and abutted, and pressed by the iron 6 to weld the waterproof accessory along the shape of the corner portion 1 by fusion bonding.

Further, as shown in FIG. 3b, the second joining surface portion A2 is bent while the first joining surface portion A1 fusion-bonded is pressed and fixed by the trowel 6, and the second joining surface portion A2 is bent. And a first wall portion D2 of the joined surface portion D, a gap 7 is formed, and hot air is sent to the gap 7 by the hot air generator 5, and the second joining surface portion A2 and the first wall surface portion D2. And are brought into a semi-molten softened state. In this state, the second joint surface portion A2 and the first wall surface portion D2 are butted against each other and pressed by the iron 6 to perform fusion bonding (see FIG. 3c).

Finally, in a state where the first joint surface portion A1 and the second joint surface portion A2 are pressed and fixed by the trowel 6, the third joint surface portion A3 is bent to join the third joint surface portion A3 and the jointed object. A gap 7 is formed between the second wall surface portion D3 of the surface portion, hot air is sent to the gap 7 by the hot air generator 5, and fusion bonding is performed by the same operation as described above.

Since the corner portion B of the waterproof accessory used in this manner is thick, even if the corner portion B is bent while being pressed by the iron 6, the waterproof accessory is unlikely to break and impair the waterproof property. The erection work can be easily performed without needing it, and the edge portion Aa of the joint surface portion A is formed to be sufficiently thin, so that it is easy to follow the joint surface portion D and workability is improved. It is possible to exert a high sealing property.

[Other Example] In the previous example, the joining surface portion A and the joined surface portion D were fusion-bonded to each other, but they may be welded to each other by using a solvent. In addition, since the edge portion Aa of the joint surface portion A is thinner than the corner portion B, it can easily follow the joint surface portion D, and there is an advantage that workability and high sealing performance can be obtained.

Further, as shown in FIG. 4, as the corner portion 1 of the building to be applied, an example of a waterproof accessory such as C1 used for waterproofing a corner of the building is shown, but as shown in C2. However, the invention can also be applied to a waterproof accessory that is used by being installed in a projecting corner of a building in which two wall surfaces 3a and 3b and a wall top surface 2b are abutted and formed to project. Furthermore, two wall surfaces 3a and 3b such as C3 are convexly abutted with each other, and a corner portion 1 where the floor surface 2a is concavely abutted and two wall surfaces 3a and 3b such as C4 are abutted concavely. Moreover, it can also be applied to the corner portion 1 that is convexly opposed to the wall top surface 2b.

Further, the shape of the waterproof accessory is not necessarily limited to the structure in which the thickness gradually increases from the joint surface portion A to the corner portion B as shown in this embodiment, and as shown in FIG. Even if only the vicinity of the corner B is thickly formed, the reinforcing portion 8 is formed near the corner B with a hard resin or a wire mesh-like reinforcing member as shown in FIG. The same effect can be obtained even with the configured structure.

Further, also in the corner B, the thickness may be gradually increased from the end of the waterproof accessory toward the abutting tops of the three joint surfaces. Further, even if only the vicinity of the inner top of the corner B is thickened, the vicinity of the top is the part that is most likely to be damaged. Therefore, the part that is easily damaged is reinforced and the waterproof property is improved. It is possible to obtain the effect of making it harder to damage.

Further, even in the corner portion 1 where four or more wall surfaces face each other, if the corner portion B is formed to be thick in the waterproof accessory having a shape along the corner portion 1, The object of the present invention is achieved. Also in this case, the respective joint surfaces of the waterproof accessory that come into contact with and come into contact with the waterproof sheet 4 are collectively referred to as joint surface portions A, and the joint surface portions A 1 of the waterproof sheet 4 come into contact with each other and join together. The part to be joined is generically referred to as a surface to be joined D.

The waterproof material is not limited to the one made of vinyl chloride, but may be another resin, but if the same material as the waterproof sheet is used, it has good fusion property when fusion-bonded, and If it has high flexibility and is thermoplastic, it has good workability when it is bonded by heat fusion. Further, any waterproofing material used by welding and joining can be used even if it is thermosetting.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
