Description

[Detailed description of the invention] This invention is a fixing member driving member that is suitably used when driving fixing members such as set anchors in order to fix a waterproof sheet installed in a tunnel to lining concrete, etc. Regarding.

Conventionally, in tunnel construction, especially when constructing near the opening, a waterproof sheet c is fixed to the primary lining concrete b cast along the ground a, using set anchors d, as shown in Figure 1. ,
In addition, reinforcing bars e assembled in the vicinity of the waterproof sheet c are welded and fixed to the set anchor d.

However, in the construction structure as described above,
When setting anchor d is driven and waterproof sheet c is fixed to the ground or primary lining concrete b, the waterproof sheet c is torn at the point where set anchor d is driven, and spring water on the ground side flows into set anchor d.
There is a problem in that the water leaks to the outside of the waterproof sheet c along the peripheral wall of the waterproof sheet c, and therefore, it has been desired to completely stop water at the place where the set anchor d is driven.

The present invention was developed in view of the above circumstances, and when a waterproof sheet is fixed with a fixing member such as a set anchor, it is possible to reliably prevent water leakage at the location where the fixing member is driven. To provide a fixing member driving member that can be easily and easily worked.

That is, in order to achieve the above object, the present invention is structured such that a heat-fusible substance is filled inside the frame, and a sheet-like support having a larger area is fixed to the back surface of the frame. In this way, for example, after fixing the driving member to the waterproof sheet and driving a fixing member such as a set anchor through the heat-fusible material in the frame of the driving member, the heat-fusible material may be softened by heating or By supplying a melted or additionally melted heat-fusible material, it is possible to eliminate the gap between the fixing member peripheral wall and the heat-fusible material that occurs when the fixing member is driven; Therefore, since the gap can be sealed in this way, it is possible to reliably prevent the inconvenience of water running along the peripheral wall of the fixing member and leaking into the tunnel. In addition, this fixing member driving member is used by fixing a sheet-like support to the driving location, but when driving a fixing member such as a set anchor, external force such as rotational force is applied to the driving member. Even if a
Inconveniences such as the driving member rotating or shifting from its attachment position do not occur, and therefore the work of driving the fixing member can be carried out reliably.

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

In the figure, reference numeral 1 indicates a fixing member driving member according to an embodiment of the present invention, and this driving member 1 is made of plastic,
The frame body 4 is made of a short-axis cylindrical frame main body 2 made of metal or the like, with a ring-shaped flange 3 integrally protruding from the outer periphery of the lower end, and a frame body 4 made of a plastic sheet, a metal plate, etc.
A sheet-like support 5 having a larger area than the frame 4 and fixed to the frame 4 by means such as fusion or adhesion; and a heat-fusible material 6 filled in the frame 4. Consisting of Here, as the heat-fusible substance 6, a hot melt adhesive whose main raw material is ethylene-vinyl acetate copolymer or the like, raw rubber, synthetic rubber, or the like is suitably used.

Further, a luminous material film 7 such as fluorescent paint is formed on the outer peripheral wall of the frame 4, and a support 5
An adhesive layer 8 is formed on the back side of the holder, and a release sheet 9 is laminated to cover the adhesive layer 8. Note that 10 in the figure is a drill guide hole. Further, the frame body main body 2 has an inner diameter of 40 to 100 mm, and a support body 5
can be formed with a diameter of 50 to 300 mm.

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. 3, the driving member 1 is attached to the fixing member driving position of the waterproof sheet 11 by the action of the adhesive layer 8. After drilling along the drill guide hole 10, a fixing member 12 such as a set anchor is driven through the frame 4 of the casting member 1 from the heat-fusible material 6 side, and the waterproof sheet 11 is attached to the lining concrete. Fixed at 13. Next, the heat-fusible substance 6 is heated with a burner or the like to soften or melt, or another heat-melted heat-fusible substance is injected into the heat-fusible substance 6 using an injection device such as a hand gun. ,
The peripheral wall 12a of the fixing member 12 is liquid-tightly coated with the heat-fusible material, and the heat-fusible material 6 generated during the casting work of the fixing member 6 and the peripheral wall 1 of the fixing member 12 are
Seal the gap between 2a and 2a. Then, the waterproof sheet 1 is attached to the external protrusion 12b of the fixing member 12.
1, reinforcing bars 14 assembled vertically and horizontally are fixed by welding.

According to the method of driving a fixing member 12 such as a set bolt using the fixing member driving member 1 described above,
Since the peripheral wall 12a of the fixing member 12 is watertightly covered with a heat-fusible material by softening or melting the heat-fusible material 6, or by separately supplying a melted heat-fusible material, the lining concrete Even if spring water from the 13 side flows from the peripheral wall at the end of the fixing member 12, it is prevented from leaking into the tunnel beyond the driving member 1, and the driving member 1 reliably stops the water. I am forced to do it. Note that when a new molten heat-fusible material is supplied to the heat-fusible material 6, since they are of the same quality, both heat-fusible materials are integrated with each other, forming a good watertight structure. Ru.

In addition, in the work of driving the fixing member 12, when drilling along the drill guide hole 10 of the driving member 1 or driving the fixing member 12 such as a set anchor, an external force such as a rotational force may be applied to the driving member 1. Even if a Since the fixing member 12 is firmly fixed, there is no problem of the driving member 1 rotating or shifting from its attached position, and therefore the driving work of the fixing member 12 can be performed reliably. It will be done.
Note that this driving member 1 has a drill guide hole 10.
is formed, so the drill position can be easily set when drilling.

Further, since the frame body 4 has a film 7 of a luminescent substance formed on its outer peripheral wall, when the fixing member 12 is driven in a dark place such as inside a tunnel, the position where the fixing member 12 is driven can be easily confirmed. It is.
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 11 with one touch by simply peeling off the cover 9, and the attachment operation on site is also easy, making it very convenient to use.

In the above embodiments, the frame main body 2 is formed into a cylindrical shape, but it is not limited to this, and may be formed into an appropriate shape, such as a bottomed cylinder, for example.
Further, the shape of the support body 5 is not limited either, and a support body 5 having a through hole 14 formed in the center may be fixed to the frame body 4. 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, the same luminous effect can be exerted on the outer peripheral wall of the frame 4, and furthermore, the casting member of the present invention can be used for various purposes such as waterproofing construction of basements and sewers, etc. Various changes may be made to the configuration within the scope of the gist of the present invention.

As explained above, the fixing member driving member of the present invention fills the frame with a heat-fusible substance, and
It is characterized in that a sheet-shaped support having a larger area is fixed to the back surface of the frame, and after driving a fixing member such as a set anchor through a heat-fusible material inside the frame, the peripheral wall of the support is fixed. Since it is possible to watertightly cover the fixing member with a heat-fusible material, it is possible to reliably prevent water from leaking from the surrounding wall of the fixing member to the outside, and to ensure that the part where the fixing member is inserted is water-tight. Due to the fixing action of the support at the location where the fixing member is driven, the driving member is prevented from rotating or shifting from its fixed position when driving the fixing member, and the workability of driving the fixing member is good. .
It is something.
