As shown in FIG. 1, the holding jig 10 for a waterproof sheet according to the present embodiment includes a main body 12 having a pair of suction cups 11 attached to the bottom, a holding plate 13, and the main body 12 and the holding plate 13. And a screw shaft 14 to be connected.

As shown in FIG. 2 which is an enlarged sectional view, the main body 12 has a flat bottom plate 15 and a support plate having an L-shaped cross section in which a horizontal portion 16 a is fixed on the bottom plate 15 by bolts and nuts 17. 16 A pair of circular holes 15a are formed on both sides of the support plate 16 in the bottom plate 15. The suction cup 11 is composed of a suction part 11a having a substantially circular shape in a plane shape that can be sucked to the floor surface, and a cylindrical pillar part 11b rising upward from a central part of the suction part 11a, integrally formed of a flexible material (synthetic resin or the like). Formed.

A columnar cover 18 having an upper bottom is covered on the outer periphery and the upper surface of the support 11b.
8 and the support 11b are inserted into the circular hole 15a of the bottom plate 15 from below. The cover 18 and the support 11b
Are provided with holes 18a, 11c penetrating in the radial direction,
Above the bottom plate 15, a retaining pin 20 penetrates these holes 18a, 11c.

The pressing plate 13 includes a rubber plate 13a for holding the waterproof sheet pieces 4c and 4a, a metal plate 13b to which the rubber plate 13a is joined, and a rubber plate 13a of the metal plate 13b.
And a bent connection fitting 13c fixed to the opposite surface. The outer circumference of the screw shaft 14 has a male screw 1 at a portion extending from the base end portion to the vicinity of the axial middle portion and a portion near the tip end portion.
4a and 14b are formed.

A screw hole 16c is formed near the upper end of the vertical portion 16b of the support plate 16, and the male screw 14a is axially movably screwed into the screw hole 16c. A handle 14 c for rotating the screw shaft 14 is attached to the base end position of the screw shaft 14 so as to be orthogonal to the screw shaft 14 main body. The handle 14c has a screw hole 16c.
The screw shaft 14 is also prevented from coming off.

The tip of the screw shaft 14 is
The screw shaft 14 is rotatably connected to the holding plate 13 via the connection fitting 13c by inserting the nut 21 into the male screw 14b on both sides of the connection fitting 13c. ing.

Next, a procedure for bonding the waterproof sheet pieces 4c and 4a on the wall surface 5 of the balcony B using the holding jig 10 will be described. Similarly to the conventional example, for example, a heat insulating material 2, a steel sheet 3 coated with a synthetic resin, and a waterproof sheet 4a are provided on a flooring made of an ALC plate or the like in a balcony B.
After laying the waterproof panel 1 integrated with the waterproof sheet 4c, the rising portion at the peripheral portion of the waterproof sheet 4a is aligned with the wall surface 5 and the waterproof sheet 4c is aligned with the wall surface 5 of the corner portion C, and if necessary, waterproof. The sheets 4a and 4c are bonded to the wall surface 5.

Then, as shown in FIGS. 3 and 4, the holding jig 10 is arranged on the waterproof sheet 4a on the floor near the corner B, and the suction cup 11 is pressed onto the waterproof sheet 4a and the main body 12 is pressed. Is fixed on the waterproof sheet 4a. At this time, the presser plate 13 is used to press the waterproof sheets 4a and 4c against
The fixing direction of the main body 12 is adjusted so as to oppose.

Subsequently, the waterproof sheets 4a, 4a,
After applying a sealing material (not shown) to the superposed portion of c,
By rotating the handle 14c of the holding jig 10, the screw shaft 14 and the holding plate 13 are made to approach the wall surface 2 side, and the waterproof sheets 4a and 4c are pressed and fixed to the wall surface 2 by the rubber plate 13a of the holding plate 13. . Thereby, the waterproof sheet 4a,
The waterproof sheets 4a, 4c can be pressed against the wall surface 2 until the 4c is completely adhered to the wall surface 2.

When the adhesion between the waterproof sheets 4a and 4c is completed, the handle 14c is rotated in the opposite direction to move the screw shaft 14 and the holding plate 13 in the direction away from the wall surface 2 and the floor surface. By removing the suction cup 11 from the upper waterproof sheet 4a, the holding jig 10 can be collected. In addition, actually, the waterproof sheets 4a, 4c
At the time of bonding, a plurality of holding jigs 10 can be used as necessary.

FIG. 5 shows a second embodiment of the present invention.
The holding jig 22 of this embodiment is configured such that, for example, two magnets 23 are attached to the lower portion of the bottom plate 15 with bolts 24 or the like instead of the suction cups 11. The holding jig 22 is a steel plate 3 included in the waterproof panel 1 (see FIG. 6).
The main body 12 is attracted and fixed by the magnet 23 by using the above. Thereby, the fixing of the main body 12 can be performed more easily.

In each of the above embodiments, the screw shaft 14
The pressing plate 13 is moved closer to or away from the main body 12 by manual rotation. Alternatively, a motor for rotating the screw shaft 14 may be provided. Also,
The axial movement of the holding plate 13 with respect to the main body 12 is controlled by the screw shaft 1.
Alternatively, for example, a hydraulic cylinder or the like may be used. Further, the holding jigs 10 and 22
In addition to bonding the waterproof sheet on the balcony B, the waterproof sheet can be used for bonding the waterproof sheet on a wall surface indoors or the like.

[0022]

As described above, according to the first aspect of the present invention,
The holding jig for the waterproof sheet is a holding jig used for holding the waterproof sheet when the waterproof sheet is adhered on the wall surface, and provided with a suction means capable of sucking on the floor surface adjacent to the wall surface. The main body, the holding plate for holding the waterproof sheet on the wall surface, the base end portion is connected to the main body, the distal end portion is connected to the holding plate to connect the main body and the holding plate, and at least one of the main body and the holding plate. And a connecting shaft that is freely movable in the axial direction.When the waterproof sheet is bonded, the waterproof sheet is temporarily fixed on the wall surface, and the suction unit is sucked onto the floor surface. By fixing the main body to the floor surface and moving the connecting shaft in the axial direction with respect to the main body or the holding plate, the holding plate approaches the waterproof sheet side, and the waterproof sheet is pressed against the wall surface by the holding plate to complete the adhesion. Can be fixed until time Thus, the waterproof sheet is securely fixed until the completion of the bonding, the peeling of the waterproof sheet and the generation of wrinkles can be suppressed, and the waterproof function can be improved.

According to a second aspect of the present invention, in the construction of the first aspect, at least one of the proximal end and the distal end of the connecting shaft is axially movable in a screw hole of the main body or the pressing plate. Since the screw shaft is screwed into, only by rotating this screw shaft, the approach of the holding plate to the main body,
The movement in the separating direction can be easily performed, and the work of pressing the waterproof sheet by the holding plate and the work of releasing the pressing force after the completion of the bonding can be performed very easily.

According to a third aspect of the present invention, in the construction of the first or second aspect, since the suction means is a suction cup, the main body can be easily placed on the floor only by suctioning the suction cup to the floor. Can be fixed.

According to a fourth aspect of the present invention, in the construction of the first or second aspect, a metal plate is disposed on the floor surface and the attraction means comprises a magnet.
There is an advantage that the main body can be easily fixed to the floor surface only by attracting the magnet to the floor surface.
