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 ground or lining concrete. Regarding.

Conventionally, in the tunnel lining section, as shown in Figure 1, a primary lining concrete b is cast on the ground a side, and a waterproof sheet c is attached to the primary lining concrete b with bolts, concrete nails, etc. 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 spring water by flowing down between the primary lining concrete b and the waterproof sheet c, the primary lining concrete b
Spring water from the side is prevented from seeping into the secondary lining concrete d side.

In this case, as shown in Figure 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. There was a problem in which water leaked into the secondary lining concrete, and a solution was needed to solve this problem.

The present invention was made to improve the above-mentioned situation, and in addition to providing a washer inside the frame, it is covered with a heat-fusible material and is further coated with an adhesive layer on the back side of the frame. It is an object of the present invention to provide a fixing member driving member that can reliably prevent water leakage at the fixing member driving part and that can be easily attached to the driving position at the site.

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

In the figure, reference numeral 1 denotes a member for driving a fixing member according to an embodiment of the present invention. A frame body 4 formed by integrally protruding 3;
It consists of a disk-shaped washer 5 made of metal or the like inserted into the lower part of the frame 4, and a heat-fusible material 6 filled in the frame 4 to cover the washer 5. Here, as the heat-fusible substance 6, a hot melt adhesive whose main raw material is ethylene monovinyl acetate copolymer or the like, raw rubber, synthetic rubber, etc. are suitably 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 to cover 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 fixed to the lining concrete 12. Next, a new thermally fused material is injected onto 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.
The head portion 11a of the fixing member 11 is coated with the coating 13 of the heat-fusible material.

According to the method for driving the fixing member 11 using the fixing member driving member 1, the fixing member 11
The head 11a of the head 11a is covered with a coating 13 to form a watertight structure. Therefore, the spring water from the lining concrete 12 side flows through the peripheral wall of the fixing member 11 and reaches the head 11.
Even if water leaks to the a side, water will not leak from the head 11a because the head 11a is watertightly covered with the film 13 of the heat-fusible material as described above. Further, after the fixing member 11 is driven through the heat-fusible material 6 in the frame 4, the head 1 of the fixing member 11 is
When a new heat-fusible substance is injected and supplied to 1a using a handgun or the like to form a coating 13, this coating 13 has the same heat-fusibility as the heat-fusibility substance 6 filled in the frame 4. Since the coating 13 and the heat-fusible material 6 in the frame body 4 are made of a material, the coating 13 and the heat-fusible material 6 in the frame body 4 have good adhesion to each other.
The material is reliably integrated with the material, forming a good watertight structure.

Further, when driving the fixing member 11, the washer body 5 in the frame body 4 is a mere disk shape, and the fixing member 11
In order to punch out this washer 5, a through hole 14 is formed in the washer 5 by the fixing member 11, but the diameter of this hole 14 is the same as the diameter of the driving shaft portion 11b of the fixing member 11. Driving shaft part 1 of fixing member 1
Since the movement of the washer body 5 is restricted by 1b, the secure state of fixation by the fixing member 11 is maintained.

Further, since the frame body 4 has a film 7 of a luminescent material formed on its outer peripheral wall, when the fixing member 11 is driven in a dark place such as a tunnel, the position where the fixing member 11 is driven can be easily confirmed. It is something. Furthermore, since an adhesive layer 8 is formed on the frame 4 and a release sheet 9 is laminated covering this, it is convenient for handling such as storage and transportation. It can be attached to the waterproof sheet 10 with a single touch by simply peeling off the waterproof sheet 9, and the attachment 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 entire head 11a of the fixing member 11 may be completely buried in the heat-fusible material 6 by filling it with the heat-fusible material 6. In this case, the vicinity of the head 11a may be completely buried in the heat-fusible material 6. By heating with a burner or the like to soften or melt the heat-fusible material 6 and make it fluid, the head 11a can be covered with the heat-fusible material 6. Further, a through hole for inserting a fixing member can be formed in advance in the washer 5, and furthermore, although the washer 5 is inserted into the frame 4 in the above embodiment,
It is also possible to integrally form the frame body 4 and the washer body 5 (for example, the frame body 4 is formed of metal, plastic, etc. into a cylindrical shape with a bottom, and the bottom part is configured as the washer body 5). Furthermore, in the above embodiment, the film 7 of the noctilucent substance was formed on the outer peripheral wall of the frame 4;
When formed of plastic, a luminous substance can be mixed into the molding material and molded to exhibit a similar luminous effect on the outer peripheral wall of the frame 4. It can be used for various purposes such as waterproofing of basements, sewers, etc., and other configurations may be modified in various ways within the scope of the gist of the present invention.

As explained above, the present invention provides a washer inside the frame, fills the frame with a heat-fusible material to cover the washer, and forms an adhesive layer on the back side of the frame. With this structure, after a fixing member such as a nail is driven through the frame, the fixing member such as a nail can be driven into the frame by heating the heat-fusible material or supplying a new heated heat-fusible material. It is possible to make a part watertight, for example, the head of a solid member can be watertightly covered with a heat-adhesive material, so even if water comes down from the surrounding wall of the fixed member, there is no risk of it leaking to the outside. Therefore, it is possible to reliably prevent water leakage at the fixing member driving part, and since an adhesive layer is formed, it can be easily attached to a waterproof sheet or the like.
