Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing a waterproof layer in a waterproof sheet construction method applied to a roof of a building, and more particularly, to a base member fixed to a body by a fixing tool. By adhering the parts and fixing the waterproof layer by the waterproof sheet to the body, the entire surface of the waterproof sheet is prevented from adhering to the body, so that the influence of the waterproof layer from the body can be reduced. The fixed part structure of a layer is related.

[0002]

2. Description of the Related Art In the above-mentioned structure for fixing a waterproof layer, conventionally, when a waterproof sheet is bonded to a base member, the waterproof sheet is uniformly bonded to the entire upper surface of the base member.

[0003]

However, the above-mentioned conventional fixing structure of the waterproof layer has the following problems. In other words, the sheet waterproofing method using the above-mentioned waterproof layer fixing portion structure does not adhere the entire surface of the waterproof sheet, and therefore the work of adhering the waterproof sheet at the time of construction can be reduced, so a new waterproof layer is formed. It is often used not only when repairing, but also when repairing the waterproof layer.
According to the above-mentioned conventional technique, since the waterproof sheet is adhered to the entire upper surface of the base member, if a new waterproof layer is applied after the old waterproof layer is removed during repair work, the waterproof layer will be removed. It takes a lot of time and it is difficult to completely remove it from the base member.Therefore, a fixing method such as bolts and screws that fix the base member to the body is reused to fix a new waterproof sheet. Hard to adopt. Therefore, it is conceivable to attach another base member to the frame while leaving the old waterproof layer, and then attach a new waterproof sheet to the base member.In this case, the base member is fixed. Therefore, a post-installed anchor or the like must be newly attached, which causes a problem of noise generation due to the perforation work for the attachment, and a problem of strength reduction due to perforation especially when the body is an ALC plate or the like.

In view of the above situation, an object of the present invention is to generate noise and reduce the strength of the structure when repairing the waterproof layer when the waterproof sheet is fixed to the structure through the base member. It is to provide a fixing part structure of a waterproof layer that can be installed without using the fixing device that is initially installed as much as possible.

[0005]

A feature of the present invention according to claim 1 is that a part of a waterproof sheet is adhered to a base member fixed to a skeleton by a fixing tool, and a waterproof layer formed by the waterproof sheet is provided on the skeleton. In order to fix it to the above, the waterproof sheet is adhered to the base member by covering the operated portion of the fixing tool in a non-adhesive state, and a mark is provided at a position corresponding to the fixing tool. .

According to a second aspect of the present invention, in addition to the above-mentioned characteristic configuration, the waterproof sheet at a portion corresponding to the operated portion of the fixing tool is bulged to form the bulge. The waterproof sheet is separated from the operated portion of the fixing tool in a non-adhesive state by the internal space of the portion, and the bulging configuration constitutes the mark.

Further, a feature of the present invention according to claim 3 is that in the feature of the above-mentioned claim 2, the bulging portion is provided independently for each of the fasteners. There is something.

Further, a feature of the present invention according to claim 4 is that in the feature of claim 2 or the feature of claim 3, the waterproof sheet constituting the bulging portion is waterproofed at other flat portions. It is formed separately from the seat.

According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the base member is a long member and ends of the waterproof sheets adjacent to each other. By joining edges together at the base member, a joint portion between adjacent waterproof layers is formed.

[0010]

In other words, according to the characterizing feature of the present invention according to claim 1, since the waterproof sheet is not adhered to the operated portion of the fixing tool such as a screw or a bolt, the waterproof layer is used for repair or the like. To remove the adhesive, you can easily remove only the waterproof sheet of the fastener, and since the adhesive does not remain on the fastener, be sure to use the existing fastener when applying a new waterproof layer. Can be reused. In addition, since the mark is given to the place corresponding to the fastener,
The location of the tarpaulin to be removed can be very easily found.

According to the characterizing feature of the present invention according to claim 2, in addition to that, the internal space formed by the bulging portion is
Since it can be used as a space for entering the tip side of a blade such as a cutter knife when cutting and removing the waterproof sheet, usability of the blade for removing the waterproof layer is improved. Moreover, since the shape of the bulging portion itself is a mark that there is a fastener at that position, even when compared with the structure in which the mark is added by means such as printing, environmental conditions such as climate and other things There is little risk that the mark will disappear even if it comes into contact.

Further, according to the characterizing feature of the present invention according to claim 3, since the bulging portions for the respective fasteners are independently formed, the swelling around the existing fasteners is exposed when the existing fasteners are exposed. All that is required is to remove the tarpaulin that forms the protrusion.

Further, according to the characterizing feature of the present invention according to claim 4, since the bulging portion is formed separately from the other portions, the bulging portion and the flat portion can be expanded when the waterproof layer is constructed. The projecting part can be constructed separately.

According to the characterizing feature of the present invention according to claim 5, in applying the waterproof layer, the waterproof layer is fixed to the frame at the portion of the long base member and the adjacent waterproof layers are connected. By repeating the above, it becomes possible to construct the waterproof layer by dividing it into predetermined areas.

[0015]

As a result, according to the present invention according to claim 1, when the old waterproof layer is removed in repair work or the like, it is only necessary to remove the minimum required waterproof sheet that can be easily found, and the old waterproof sheet is not used. Since a new waterproofing layer can be constructed by effectively reusing the fasteners used for the waterproofing layer, the amount of waste material is small, there is no need for new drilling, there is less construction work, and noise is generated. The structure of the fixed part of the waterproof layer was excellent so that the replacement work of the waterproof layer could be done less often.

According to the second aspect of the present invention, in addition to that, it is possible to improve the usability of the blade at the time of removing the waterproof sheet and reduce the possibility that the mark disappears. There is an effect that replacement work can be done efficiently.

Furthermore, according to the present invention of claim 3,
When replacing the waterproof layer, it is only necessary to remove the waterproof sheet in the immediate vicinity of each fixing device, which has the effect of further reducing the amount of waste material.

Further, according to the present invention of claim 4, when applying the waterproof layer, it is possible to adopt a work mode in which the flat portion which is simply laid is preceded and the bulging portion is applied later. The effect is that construction can be done even more efficiently.

According to the present invention of claim 5,
Since the structure for fixing the waterproof sheet can also be used as the structure for connecting the waterproof layers, it is possible to perform the fixing work of the waterproof sheet separately, so the replacement work of the waterproof layer as a whole is less likely to fail. And there is an effect that it can proceed efficiently.
