Description

  The present invention relates to a waterproof sheet fixture that fixes a waterproof sheet provided on a waterproof base to the waterproof base.

Conventionally, as this type of waterproof sheet fixture, the fixture body is made of a metal disc, and a fixing portion (hot melt adhesive layer) on which the waterproof sheet can be bonded and fixed to the upper surface of the fixture body. (For example, refer to Patent Document 1).
This waterproof sheet fixture has a screw insertion hole formed in the central portion of the fixture main body, and is configured to be fixed to the waterproof base with a screw member inserted through the screw insertion hole.

  When fixing to a waterproof base, the screw member used may differ depending on the type of the waterproof base. For example, when the waterproof base is concrete, a hole for screw member installation is drilled in the concrete, and a plug anchor or the like is provided in the hole. In many cases, a method is used in which the screw member is fixed to the waterproof base via the plug anchor. When the waterproof base is a metal roof such as a folded plate, a tapping screw is often used as a screw member, and the method is fixed by forcibly screwing the waterproof base into the waterproof base.

  Regarding the fixing of the waterproof sheet to the waterproof sheet fixing tool, for example, the waterproof sheet is put on the waterproof sheet fixing tool installed on the waterproof base, and the fixing tool body is heated from above by using the electromagnetic induction heating device. There was a method of fixing the waterproof sheet to the fixture body by melting the adhesive layer on the fixing part.

When refurbishing the tarpaulin installed as described above, for example, a new tarpaulin for repair from the top of the tarpaulin at a location shifted laterally from the planar position of the tarpaulin fixing tool already installed. There is a method (for convenience, referred to as a first conventional method) implemented by installing a fixing tool and adhering a repairing waterproof sheet from the waterproof sheet fixing tool.
However, according to this repair method, when installing a waterproof sheet fixing tool for repair, it is necessary to install a screw member on the waterproof base, and noise and vibration associated with the work propagate to the waterproof base, There is a problem that it is not preferable.

  As a repair method to alleviate this noise vibration problem, for example, the waterproof sheet is cut along the periphery of the already installed waterproof sheet fixture, and the waterproof sheet fixture is reheated to bond the fixing layer. There is a method in which the tarpaulin portion where the cut is made is removed from the tarpaulin fixing tool. Then, using the waterproof sheet fixing tool exposed in the cut portion as it is, providing a new adhesive layer thereon, laying a waterproof sheet for repair from above and bonding it to the waterproof sheet fixing tool ( For convenience, it is referred to as a second conventional method) (see, for example, Patent Document 1).

JP 2002-88986 A (FIGS. 1-4)

According to the above-described conventional waterproof sheet fixture, if the waterproof sheet is modified by the first conventional method, noise and vibration are generated along with the installation of the screw member as described above. is there.
In addition, if the waterproof sheet is repaired by the second conventional method, it takes much time to reliably remove the old adhesive layer from the fixing portion of the waterproof sheet fixture, and the work efficiency of the waterproof sheet repair is reduced. There is a problem. If the old adhesive layer is not removed, the adhesive performance may not be sufficiently exerted even if a new adhesive layer is applied thereon.

  In the second conventional method, it is conceivable to replace the waterproof sheet fixture with a new one by removing the screw member instead of covering with a new adhesive layer. However, once the screw member screwed to the plug anchor or the like is removed, the plug anchor is loosened, and even if the screw member is screwed again, a sufficient fixing force may not be obtained.

  Accordingly, an object of the present invention is to provide a waterproof sheet fixture that can efficiently perform the waterproof sheet repair work while eliminating the above-mentioned problems and suppressing the generation of noise and vibration.

  A feature of the present invention is a waterproof sheet fixture that fixes a waterproof sheet provided on a waterproof base to the waterproof base, the fixture main body being freely fixable to the waterproof base, and the fixture main body. A cover member that can be exchangeably attached, and the cover member is provided with a fixing portion that allows the waterproof sheet to be bonded and fixed.

According to the present invention, it is provided with a fixing body that can be fixed to the waterproof base and a cover member that is replaceably attached to the fixing body, and the fixing member that can bond and fix the waterproof sheet to the cover member. Since it is provided, the cover member can be attached to the fixture body in a replaceable manner, and the waterproof sheet can be adhered to the fixing portion of the cover member.
Accordingly, when installing the waterproof sheet on the waterproof base, the fixing body is fixed to the waterproof base, and for example, a cover member is attached to the fixing body, and the waterproof sheet is adhered to the cover member, The sheet can be stably installed on the waterproof base.

  In addition, if a locking mechanism, an engagement mechanism, a fitting mechanism, or the like is employed as an attachment / detachment mechanism between the fixture main body and the cover member, a waterproof sheet is previously bonded to the cover member, and the cover member in that state is attached. It is also possible to employ a work sequence for attaching to the fixture body.

  In addition, when refurbishing the tarpaulin installed as described above with a new tarpaulin over the years, the old tarpaulin before the repair is cut out around the installed cover member, and the fixture together with the cover member Can be removed from the body. Further, the fixing device main body remains fixed to the waterproof base, for example, a new cover member is replaced with the fixing device main body, and the new waterproof sheet is bonded to the cover member, thereby renovating the waterproof sheet. be able to. Also in this case, as described above, it is also possible to adopt the order in which the waterproof sheet is attached to the cover member in advance with the waterproof sheet adhered to the cover member.

That is, since the fixture main body can be reused while being fixed to the waterproof base, it is not necessary to remove the screw member fixing the fixture main body to the waterproof base, and a stable installation state can be maintained.
Furthermore, since it is not necessary to remove the fixture body, it is no longer necessary to drill a fixing hole in the waterproof base, preventing noise and vibration that would have occurred in those operations, and proceeding with the repair work silently. be able to.

In addition, since the cover member used after the renovation is not the old cover member that was originally installed, but a new one can be used, there is no need to remove the old adhesive layer as in the conventional case, and the cover member can be installed efficiently. it can. And the adhesive performance of a cover member and the new waterproof sheet for repair can also be maintained, without reducing.
As a result, the waterproof sheet can be repaired efficiently while suppressing the generation of noise and vibration.

  In this invention, the said cover member is comprised with the plate-shaped body which can be arrange | positioned in the state which overlaps on the said fixture main body, The attachment / detachment mechanism of the said cover member to the said fixture main body is attached to the said cover member. A screw insertion hole formed; a screw member that can be inserted through the screw insertion hole; and a screw hole that is formed in the fixture main body and that allows the screw member inserted through the screw insertion hole to be screwed. It is preferable to be configured.

According to this structure, the upper surface of the plate-shaped body which comprises a cover member can be utilized effectively as a fixing | fixed part, and a waterproof sheet can be fixed more strongly using the wide range of a plate surface.
Further, since the attachment / detachment mechanism is configured by the screw insertion hole of the cover member, the screw member, and the screw hole of the fixture main body, the cover for the fixture main body can be obtained by screwing the screw member into the screw hole. The member can be easily attached and detached.

  In the present invention, the total number of the screw holes is set to be larger than the total number of the screw insertion holes, and the screwing destination of the screw member through which the screw insertion holes are inserted is selected from among the plurality of screw holes. It is preferable to be configured to be selectable.

According to this configuration, when the cover member is attached to and detached from the fixture main body, the screwing destination of the screw member can be selected and attached from the plurality of screw holes provided in the fixture main body.
Therefore, when it is difficult for the screw member to enter the target screw hole, the screw member can be changed to another screw hole that smoothly enters and screwed, so that the cover member can be attached to the fixture body efficiently and reliably. Can be implemented.
Examples of the screw member that is difficult to enter the screw hole include deformation of the screw hole, low dimensional accuracy, and corrosion generated around the screw hole until the waterproof sheet is repaired.

  Further, since the screw insertion holes of the cover member are smaller than the total number of screw holes of the fixture main body, the cross-sectional defect of the cover member due to the holes can be reduced, and the strength reduction can be mitigated. As a result, the whole waterproof sheet fixture can be designed to be thin by using a thin plate as the cover member. By making the waterproof sheet fixture thin, the rising of the waterproof sheet installed thereon can be reduced, and obstacles such as tripping when walking on the upper part are less likely to occur.

  In the present invention, it is preferable that the attaching / detaching mechanism of the cover member to the fixture main body is constituted by a fitting portion provided in the fixture main body and the cover member.

According to this structure, attachment of the cover member with respect to a fixing tool main body by a fitting part can be implemented by a fitting part instead of a screw member.
Therefore, it is not necessary to prepare a separate screw member for attaching / detaching the cover member to / from the fixture main body, so that the number of parts can be reduced and member management can be facilitated.
Furthermore, since the attaching / detaching operation itself only needs to fit the fitting portion, the attaching / detaching operation can be performed easily and quickly without taking time and effort.

  In the present invention, it is preferable that the cover member is configured so as to cover the fixture main body while being attached to the fixture main body and to have an outer peripheral portion grounded to the waterproof base.

  According to this structure, the protective effect with respect to a fixing tool main body can be exhibited by covering the whole fixing tool main body with a cover member. In particular, since the cover member is configured so that the outer peripheral portion is grounded to the waterproof base, sealing performance is improved.For example, condensed water generated in a gap between the waterproof sheet and the waterproof base is attached to the fixture body side. It becomes easy to prevent intrusion. As a result, corrosion of the fixture body can be suppressed, and durability can be improved.

  In addition, when a screw member is used to fix the fixture body to the waterproof base, the screw member may be loosened by vibration transmitted from the waterproof sheet (vibration generated by wind lift, etc.), but the cover member By covering the fixture body with the cover member, the head part of the screw member can be suppressed by the cover member, and the phenomenon that the waterproof sheet is pierced from the lower side by the protruding screw member head part (pop-up phenomenon) can be prevented. The performance can be maintained.
