Description

[Detailed description of the invention] This invention is a fixing member driving member used when driving fixing members such as nails in order to fix a waterproof sheet installed in a tunnel to the earth or lining concrete. Regarding.

Conventionally, in the tunnel lining section, as shown in Figure 1, primary lining concrete b is cast on the ground a side, and a waterproof sheet C is attached to this concrete lining b by bolts and concrete nails. It is fixed by nailing with a fixing member, and then a secondary lining concrete d is placed on this waterproof sheet C, and the waterproof sheet C is interposed between the primary and secondary lining concrete b and d. By draining the spring water by flowing down between the primary lining concrete b and the waterproof sheet C, spring water from the concrete lining b side is prevented from seeping into the secondary lining concrete d side. are doing.

In this case, as shown in Fig. 2, when the waterproof sheet c is fixed to the primary lining concrete b by driving fixing members e such as nails, spring water flows along the peripheral wall of the fixing member e to the ground side. 96 while leaking to the secondary lining concrete side
(There was a need to resolve this issue.

The present invention was made in order to improve the above-mentioned problems, and the purpose is to provide a member for driving a fixing member such as a nail that can reliably prevent water leakage at the driving part of the fixing member such as a nail. .

That is, in order to achieve the above object, the present invention includes a washer provided in a frame, and a heat-fusible material is filled in the frame to cover the washer, and a nail is inserted through the frame. After driving the fixing member such as, the heat-fusible material is heated or a new heated heat-fusible material is supplied to make the place where the fixing member is driven into the frame watertight. This is what I did.

Hereinafter, one embodiment of the present invention will be described with reference to FIG.

In the figure, reference numeral 1 denotes a fixing member driving member according to a second embodiment of the present invention, and this driving member 1 has a spring-shaped flange on the outer peripheral edge of the lower end of a short-axis cylindrical frame main body 2 made of plastic or the like. 3 integrally projecting, a disc-shaped washer 5 made of metal or the like inserted into the lower part of this frame 4, and a washer 5 that covers this washer 5 and is inserted into the frame 4. and a heat-fusible material 6 filled with the heat-fusible material 6.

Here, the heat-fusible material 6 is a material into which a fixing member such as a nail can be driven and which softens and melts and becomes fluidized by heating, such as a hot-melt adhesive whose main component is ethylene-vinyl acetate copolymer or the like. Agents and the like are preferably used.

Further, a luminescent material film 7 such as fluorescent paint is formed on the outer peripheral wall of the frame 4, and an adhesive layer 8 is formed on the back side of the frame 4. A release sheet 9 is laminated covering it.

Next, to explain how to use the above-mentioned fixing member driving member 1, taking as an example a case where a waterproof sheet disposed in a tunnel is fixed to lining concrete, the release sheet 9 is peeled off, and as shown in FIG. As shown in FIG. 2, the driving member 1 is attached to the fixing member driving position of the waterproof sheet 10 by the action of the adhesive layer 8.

Then, as shown in FIG. 5, fixing members 11 such as nails and bolts are driven through the frame 4 of the driving member 1 from the heat-fusible material 6 side, and the waterproof sheet 10 is inserted into the lining concrete 12. Fixed to.

Next, a new heat-melted heat-fusible material is injected and supplied to the end surface of the head 11a that remains exposed to the outside of the fixing member 11 using an injection device such as a hand gun, and the fixing member is removed. 11 is covered with a coating 13 of this heat-fusible material.

Thus, a fixing member 1 using the fixing member driving member 1
According to the first driving method, the head portion 11a of the fixing member 11 is covered with the coating 13, forming a watertight structure.

Therefore, even if spring water from the lining concrete 12 side flows along the peripheral wall of the fixing member 11 and seeps into the head 11a side, the head 11a is watertight with the heat-fusible material coating 13 as described above. Since it is covered, water does not leak from the head 11a.

Further, after the fixing member 11 is driven through the heat-fusible material 6 in the frame 4, a new heat-fusible material is injected and supplied to the head 11a of the fixing member 11 using a hand gun or the like, and the coating 13 is When forming the coating 13, since the coating 13 is made of the same heat-fusible material as the heat-fusible material 6 filled in the frame 4, the heat-sealing between the coating 13 and the frame 4 is prevented. The coating 13 has good adhesion to the heat-fusible substance 6 and the heat-fusible substance 6 in the frame 4, and a good watertight structure is formed.

In addition, when driving the fixing member 11, the washer body 5 inside the frame body 4
is a mere disk shape, and since the fixing member 11 punches out this washer 5, a through hole 14 is formed in the washer 5 by the fixing member 11. The diameter is the same as that of the shaft portion 11b, and therefore, the movement of the washer body 5 is regulated by the driving shaft portion 11b of the fixing member 1, so that the secure state of fixing by the fixing member 11 is maintained.

Further, since the frame body 4 has a film 7 of a luminescent substance formed on its outer peripheral wall, when the fixing member 11 is driven in a dark place such as inside a tunnel, the position where the fixing member 11 is driven can be easily confirmed. It is.

Furthermore, an adhesive layer 8 is formed on the frame 4, and a release sheet 9 is laminated to cover this, making it convenient for handling such as storage and transportation. It can be attached to the waterproof sheet 10 with one touch by simply peeling off the adhesive 9, and the adhesive operation at the site is also easy, making it very convenient to use.

In the above embodiment, after the fixing member 11 is driven in, the heat-fusible material is newly supplied, but the axial length of the frame 4 is longer than the axial length of the head 11a of the fixing member 11 The fixing member 1 is formed by filling it with a heat-fusible substance 6.
1 may be completely buried in the heat-fusible material 6. In this case, the vicinity of the head 11a is heated with a burner or the like to soften or melt the heat-fusible material 6. By fluidizing the heat-fusible material 6, the head portion 11a can be coated with the heat-fusible material 6.

Further, a through hole for inserting the fixing member can be formed in advance in the washer 5, and furthermore, although the washer 5 was inserted into the frame 4 in the above embodiment, it is possible to form the washer 5 with the frame 4. 5 is integrally formed (for example, the frame 4 is made of metal, plastic,
It is also possible to form it into a cylindrical shape with a bottom and configure the bottom part as the washer body 5).

Furthermore, in the above embodiment, the film 7 of the luminous substance was formed on the outer peripheral wall of the frame 4, but when the frame 4 is made of plastic, the luminous substance may be mixed into the molding material and molded. However, a similar nocturnal effect can be exerted on the outer peripheral wall of the frame 4, and the casting member of the present invention can also be used in basements and sewers.

It can be used for various purposes such as waterproofing, and other configurations may be modified within the scope of the gist of the present invention.

As explained above, the present invention provides a washer body within a frame body, and a heat-welding material that can cover this washer body and drive a fixing member such as a nail into the frame body, and that softens or melts and becomes fluidized by heating. Since it was configured to be filled with an adhesive substance,
After driving a fixing member such as a nail through the frame, the location where the fixing member is driven into the frame is fixed by heating the heat-fusible material or by supplying a new heated heat-fusible material. It can be made watertight, for example, the head of the fixing member can be watertightly coated with a heat-adhesive material, so even if water runs down from the surrounding wall of the fixing member, there is no risk of it leaking outside. It is possible to reliably prevent water leakage at the fixing member driving part.
