Description

  The present invention relates to a sheet waterproof structure for waterproofing a casing, and a method for constructing a sheet waterproof structure for constructing such a sheet waterproof structure.

  In recent years, with the demand for higher durability of buildings, for example, on many rooftops and verandas of buildings, a waterproof sheet structure in which a waterproof sheet (resin sheet) is installed (for example, patents) has been adopted. Reference 1).

  In this waterproof sheet structure, for example, at least a part of the floor portion is covered (laid) with a waterproof sheet, but the waterproof sheet is fixed to the floor portion (casing) in a plurality of predetermined shapes. Fixing the fixture (steel plate) to the floor using a fixing screw or the like, and further joining the upper surface of the fixture and the lower surface of the waterproof sheet in these fixtures, the floor portion via the fixture And the waterproof sheet are joined. Thereby, while waterproofing with respect to rain water etc. is given to a housing, a waterproof sheet is fixed to a housing without peeling off with respect to a wind.

  However, when the sheet waterproof structure having such a configuration is applied for renovation of a water tank provided in the pool, when the water tank is made of, for example, fiber reinforced plastic (FRP), If the fixing tool is fixed to the water storage tank using a fixing screw for laying the housing, the water stored when a crack or a through hole is unintentionally formed in the laid waterproof sheet. Such a problem may occur that liquid such as water leaks to the outside of the water storage tank through the hole for fixing the fixing screw formed in the water storage tank.

  In addition, because the fixing screw is made of FRP and fixed to the water tank, excellent fixing strength cannot be obtained, or when the water tank is composed of a hard foam material and a surface layer made of FRP, it is fixed. Due to the fixing of the screw, water enters between the hard foam material and the surface layer, and this also causes a problem that peeling occurs.

  Therefore, without using such a fixing screw, that is, without performing processing in the thickness direction such as formation of a hole in the water storage tank (casing), the waterproof sheet is in a state where the fixing tool is fixed to the water storage tank. However, there is a demand for providing a waterproof sheet structure laid on the water tank.

Moreover, in FIG. 1, the floor part and wall part with which a housing is provided are partially illustrated, without showing the whole sheet | seat waterproof structure for convenience of explanation.

  In the present embodiment, a case where the waterproof sheet structure 1 is applied to the housing 10 (structure) such as a water tank provided in the pool for repair will be described as an example.

  The casing 10 has a rectangular floor portion 11 and a rectangular frame-shaped wall portion 12 (rise portion) provided so as to surround the outer edge of the floor portion 11. ing.

  By configuring the casing 10 to include such a floor portion 11 and the wall portion 12, the casing 10 has a concave portion having a bottom portion at the center thereof, whereby water is contained in the concave portion. The water tank of the pool to be stored is configured (see FIG. 1). The casing 10, that is, the water storage tank, is usually made of fiber reinforced plastic (FRP) and is fixed in a state of being housed in a space provided in a concrete frame.

  In the present embodiment, the waterproof sheet structure 1 is configured to cover the casing 10 having such a configuration, that is, the frame-shaped wall portion 12 and the floor portion 11 constituting the bottom portion with a waterproof sheet 30. The waterproof sheet 30 laid in the recess of the casing 10, the arrangement member 20 (fixing tool) for fixing the waterproof sheet 30, and the fixing jig fixed to the casing 10 and for fixing the arrangement member 20 50 (fixed disk) (see FIGS. 1 and 2).

  Hereinafter, the placement member 20 is fixed to the corner 13 (boundary portion) formed by the floor portion 11 and the wall portion 12 using the fixing jig 50, and the placement member 20 is interposed therebetween. The case where the laid waterproof sheet 30 is fixed to the housing 10 will be described.

  The arrangement member 20 is fixed to the housing 10 by the fixing jig 50 in a state where the arrangement member 20 is arranged at the corner 13 of the floor portion 11 and the wall portion 12. At the same time, it is laid so as to cover the concave portion of the housing 10, that is, the floor portion 11 and the wall portion 12, and is fixed to the housing 10 via the arrangement member 20, thereby ensuring the waterproof property of the housing 10. The

  That is, the waterproof sheet 30 is exposed to water and sunlight, and the casing 10 is prevented from being directly exposed to water and sunlight, so that the waterproofness of the casing 10 is ensured. Further, the upper surface of the arrangement member 20 and the lower surface of the waterproof sheet 30 are joined, and the arrangement member 20 is fixed to the housing 10 via the fixing jig 50, whereby the housing is arranged via the arrangement member 20. The waterproof sheet 30 is joined and fixed to 10.

Hereinafter, each part with which the sheet | seat waterproofing structure 1 is provided is explained in full detail.
The arrangement | positioning member 20 is arrange | positioned in the corner | angular part 13 vicinity of the floor part 11 and the wall part 12 as above-mentioned (refer FIG. 2).

  The arrangement member 20 includes a metal plate and a resin layer composed of a resin that covers the surface of the metal plate. In the present embodiment, the first portion 21 (bottom portion) has a flat shape as a whole. And the second part 22 (rising surface), the second part 22 is erected from one long side of the first part 21, and the side shape is L-shaped.

  When the first part 21 and the second part 22 are arranged in the corner 13, the first part 21 is positioned so as to correspond to the floor part 11, and the first part 21 and the second part 22 correspond to the wall part 12. The position of the second part 22 is set. In addition, in this embodiment in which the floor portion 11 has a rectangular shape, a total of four corners 13 formed by the floor portion 11 and the wall portion 12 are formed, and such first and second portions 21 and 2 are formed. A total of four arrangement members 20 constituted by the portions 22 are arranged corresponding to the respective corners 13.

  Moreover, since the shape of the housing | casing 10 where waterproofing is constructed | assembled naturally is various, as the arrangement | positioning member 20, the thing of several types of shapes is prepared previously, and the corner with which the housing 10 actually constructed | installed is equipped is provided. The arrangement member 20 including the first part 21 and the second part 22 that match the shape of the part 13 is selected. And the arrangement | positioning member 20 is arranged so that the 1st part 21 and the 2nd part 22 may correspond to the shape of the floor part 11 and the wall part 12 in the said corner 13.

  Furthermore, the position where the waterproof sheet 30 should be fixed to the housing 10 via the arrangement member 20 is not limited to the corner portion 13, but the center portion of the floor portion 11 and the wall portion 12, and the corner portion 13 of the wall portion 12. The arrangement | positioning member 20 prepared beforehand corresponding to the shape of these positions is selected, and it arrange | positions with respect to each position, respectively.

  Each of the first part 21 and the second part 22 has a plurality of through-holes 25 penetrating in the thickness direction provided at substantially equal intervals along the longitudinal direction.

  A bending portion 52 provided in the fixing jig 50 is inserted into the through hole 25 with the fixing jig 50 facing the floor 11, and in this state, the bending portion 52 is bent so as to contact the upper surface of the arrangement member 20. Thus, the arrangement member 20 is fixed to the fixing jig 50. Furthermore, since the lower surface of the main body 51 that is provided in the fixing jig 50 and is integrally formed with the bent portion 52 is joined to the housing 10, the arrangement member 20 is attached to the housing 10 via the fixing jig 50. Fixed.

  Moreover, the arrangement | positioning member 20 is comprised by the metal plate and the resin layer which coat | covers the surface of this metal plate. That is, the arrangement | positioning member 20 equips the surface of the side by which the waterproof sheet 30 is fixed with a resin layer. Thus, by covering the surface of the metal plate with the resin layer, corrosion of the metal plate can be reliably prevented. Moreover, it can be reliably bonded to the waterproof sheet 30 by using a welding method and a heat sealing method described later.

  The metal plate is made of, for example, a steel plate such as a stainless steel plate or an iron plate, an aluminum plate, a copper plate, or the like, and is preferably a steel plate. Thereby, the arrangement | positioning member 20 can be made into the outstanding intensity | strength.

  Moreover, the thickness of the arrangement | positioning member 20 is although it does not specifically limit, It is preferable that it is about 0.1 mm or more and 3 mm or less, and it is more preferable that it is about 0.3 mm or more and 2.5 mm or less.

  Furthermore, the width of the arrangement member 20 is not particularly limited, but is preferably about 30 mm or more and 200 mm or less, and more preferably about 50 mm or more and 150 mm or less.

  Examples of the resin constituting the resin layer include a vinyl chloride resin such as polyvinyl chloride, a polyolefin resin, an ethylene vinyl acetate copolymer, and the like. Polyvinyl chloride is preferred although it can be used. That is, it is preferable that it is the same or the same as the resin constituting the waterproof sheet 30 described later. Thereby, the adhesiveness of the resin layer and the waterproof sheet 30 can be improved. Furthermore, since polyvinyl chloride is excellent in solvent weldability and heat-fusibility, the above effects can be exhibited more significantly and corrosion of the arrangement member 20 can be more reliably prevented.

  Moreover, other materials, such as a plasticizer mentioned in the constituent material of the waterproof sheet 30 mentioned later, a stabilizer, may be contained in resin which comprises this resin layer.

  The thickness of the resin layer is not particularly limited, but is preferably 0.1 mm or more, more preferably 0.3 mm or more and 0.8 mm or less. Thereby, joining of the waterproof sheet 30 and the resin layer, that is, the waterproof sheet 30 and the arrangement member 20 can be firmly joined.

  The arrangement member 20 is only required to be fixed to the casing 10 via the fixing jig 50. In addition to fixing by the fixing jig 50, the casing 10 (the floor portion 11 and the wall portion 12) is formed by an adhesive layer. It may be fixed directly. Thereby, the arrangement | positioning member 20 can be fixed more firmly with respect to the housing 10. FIG. In this case, the separation distance between the arrangement member 20 and the housing 10 is set according to the thickness of the main body 51 provided in the fixing jig 50 described later. Therefore, an adhesive layer having a desired thickness can be formed by selecting the fixing jig 50 including the main body 51 having an appropriate thickness according to the thickness of the adhesive layer to be formed. .

  Moreover, the upper surface of the arrangement | positioning member 20 penetrates so that the bending part 52 bent in the state penetrated to the through-hole 25 may be included besides the case where it is comprised with a flat surface as shown in FIGS. You may provide the recessed part which makes the circle centering on the hole 25. FIG. Thereby, since it can prevent reliably that the bending part 52 bent is protruding to the waterproof sheet 30 side, the waterproof sheet 30 joined to the arrangement | positioning member 20 can be reliably comprised with a flat surface.

  In addition, although the arrangement | positioning member 20 was provided with the 1st part 21 and the 2nd part 22 in this embodiment, and the side surface shape had comprised the L shape, it is not limited to the thing of this structure, For example, The first part 21 and the second part 22 are not connected to each other, and may include the first part 21 and the second part 22 as separate bodies, or the first part 21 and the second part 22 Any one of the above may be provided alone.

  The fixing jig 50 (fixed disk) includes a disk-shaped main body 51 and a bent portion 52 (protruding portion) that is formed integrally with the main body 51 so as to protrude from the main body 51. The bending member 52 is bent in a state where the bending portion 52 is inserted into the through hole 25 provided in the arrangement member 20, so that the arrangement member 20 is disposed on the fixing jig 50 at a position corresponding to the through hole 25. (First part 21 and second part 22) are fixed. Further, in this state, the main body 51 (fixing jig 50) is fixed to the housing 10 (the floor 11 and the wall 12). Thereby, the arrangement | positioning member 20 (1st part 21 and 2nd part 22) is fixed with respect to the housing 10 (floor part 11 and wall part 12) via the fixing jig 50 (FIGS. 1-4). reference).

  The arrangement member 20 is fixed to the casing 10 (the floor portion 11 and the wall portion 12) via the fixing jig 50, and the waterproof sheet 30 is joined to the surface of the arrangement member 20 so that the casing 10 is joined. The waterproof sheet 30 can be fixed to the housing 10 without performing processing in the thickness direction. Therefore, even if a crack or a through hole is formed unintentionally in the laid waterproof sheet 30, it is possible to accurately prevent the occurrence of water leakage outside the housing 10 due to the fixing of the fixture.

  Further, since the waterproof sheet 30 can be fixed to the casing 10 without performing processing in the thickness direction of the casing 10, the casing 10 is made of fiber reinforced plastic as in the present embodiment. Further, the waterproof sheet structure 1 of the present invention is suitably applied.

  Furthermore, when the housing 10 is composed of a hard foam material and a surface layer made of FRP, the formation of a hole for fixing the fixing screw can be omitted. It is possible to accurately prevent water from entering between the hard foam material and the surface layer and causing peeling.

  The main body 51 (substrate) is formed of a metal plate having a perfect circle shape in plan view and a vertical cross-sectional shape of which is a rectangular shape. That is, it is a metal plate in which the entire shape with a constant thickness forms a disk shape from the center side toward the edge side.

  Such a main body 51 is fixed to the housing 10 (the floor 11 and the wall 12) via an adhesive layer (not shown). Thereby, the fixing jig 50 can be fixed to the housing 10 with an excellent fixing strength.

  As the metal plate constituting the main body 51, the same metal plate as described above for the metal plate included in the disposing member 20 can be used. It does not matter.

  The thickness of the main body 51 is not particularly limited, but is preferably about 0.1 mm or more and 3.0 mm or less, and more preferably about 0.4 mm or more and 2.0 mm or less.

  Furthermore, although the diameter of the main-body part 51 is not specifically limited, It is preferable that it is about 20 mm or more and 150 mm or less, and it is more preferable that it is about 40 mm or more and 100 mm or less.

  The adhesive layer is mainly composed of, for example, an adhesive composed of at least one of an acrylic adhesive, an epoxy adhesive, a silicone adhesive, and a rubber adhesive as a main material.

  Moreover, this main-body part 51 may be provided with the through-hole penetrated in the thickness direction, or the hole opened in the lower surface (surface on the opposite side to the bending part 52). Thereby, since the contact area of the main-body part 51 and an adhesive bond layer increases, the main-body part 51 and an adhesive bond layer can be joined by more excellent joining strength. Moreover, although there may be one through hole or a plurality of these through holes and holes, it is preferable to have a plurality. Thereby, the said effect is exhibited more notably.

  The bent portion 52 is formed integrally with the main body 51, that is, the connecting portion between the main body 51 and the bent portion 52 is continuously formed of the same member. Further, in this first configuration example, the overall shape is constituted by a solid rod-like body, and in a state before the arrangement member 20 is fixed, as shown in FIG. From the upper surface so as to protrude substantially perpendicular to the upper surface.

  In the bent portion 52, the through hole 25 provided in the arrangement member 20 is inserted at a position where the fixing jig 50 is interposed between the arrangement member 20 and the housing 10, and the bent portion 52 is placed on the upper surface of the arrangement member 20 in this state. (See FIGS. 2 and 5), and thereby the arrangement member 20 is fixed to the fixing jig 50.

  Moreover, this bending part 52 is formed with the intensity | strength which can be bent in the arbitrary positions of the longitudinal direction using tools, such as a person's finger | toe, a hammer, and a pliers. Thereby, the bent part 52 can be bent at a position corresponding to the thickness of the arrangement member 20. Therefore, the arrangement member 20 can be fixed to the fixing jig 50 with high positional accuracy. Further, even when the arrangement members 20 having different thicknesses are used, the arrangement members 20 can be bent at desired positions according to the thicknesses. It becomes possible to cope with. That is, the number of parts when constructing the waterproof sheet structure 1 can be reduced.

  In addition, by forming the bent portion 52 with a rod-like body like this configuration, it can be formed relatively easily as having a strength that can be bent at an arbitrary position in the longitudinal direction.

  Such a bent portion 52 is made of the same metal material as the metal plate constituting the main body portion 51.

  The diameter of the bent portion 52 is not particularly limited, but is preferably about 0.1 mm or more and 3 mm or less, and more preferably about 0.3 mm or more and 2.5 mm or less.

  Further, the length of the bent portion 52 is not particularly limited, but is preferably about 10 mm to 75 mm, and more preferably about 15 mm to 50 mm.

  By setting the size (diameter and length) of the bent portion 52 within such a range, the above-described function as the bent portion 52 can be reliably exhibited.

Note that the fixing jig 50 may include a resin layer that covers the surface of both the main body 51 and the bent portion 52. Thus, by covering the surface of the fixing jig 50 with the resin layer, corrosion of the fixing jig 50 can be reliably prevented. In addition, it is possible to realize the bonding between the resin layer and the waterproof sheet 30 in the bent portion 52 that is bent from the through hole 25 of the arrangement member 20.
In addition, as this resin layer, the thing similar to the resin layer with which the arrangement | positioning member 20 is provided is mentioned.

  By providing the fixing jig 50 provided with the main body 51 and the bent part 52 having such a configuration corresponding to the plurality of through holes 25 provided in the arrangement member 20 (the first part 21 and the second part 22), respectively. The arrangement member 20 (the first part 21 and the second part 22) is fixed to the housing 10 (the floor part 11 and the wall part 12) via the fixing jig 50.

  Here, among the waterproof sheets 30 laid on the housing 10, for example, those laid on the floor portion 11 may be stressed in the direction in which the waterproof sheet 30 contracts, so that the four wall portions 12 The stress is likely to be generated in the direction toward the center of the floor 11. On the other hand, the fixing strength in the first part 21 of the arrangement member 20 fixed by the fixing jig 50 by bending the bent portion 52 tends to increase in the direction opposite to the direction in which the bent portion 52 is bent.

  Further, in the arrangement member 20 fixed to the housing 10, for example, the first portion 21 fixed to the floor portion 11 is separated from the wall portion 12 erected from the end portion of the floor portion 11 by a predetermined distance. It is fixed with. On the other hand, the positioning accuracy of the first part 21 fixed by the fixing jig 50 by the bending of the bent part 52 tends to increase in the direction in which the bent part 52 is bent.

  For these reasons, the bending direction of the bent portion 52 when fixing the first portion 21 (arrangement member 20) to the fixing jig 50 provided on the floor portion 11 coincides with the direction toward the wall portion 12 to be erected. It is preferable to make it. As a result, both the fixing strength and positioning accuracy of the first portion 21 (arrangement member 20) fixed by the fixing jig 50 can be improved.

  Therefore, as in the present embodiment, when one fixing jig 50 is provided for each of the plurality of through holes 25 provided in the first part 21, the bent parts 52 provided in each fixing jig 50 are provided. Are bent with respect to the proximal wall portion 12, and as a result, there are preferably different directions in which the bent portions 52 of the respective fixing jigs 50 are bent (see FIG. 3). ). That is, it is preferable that at least one of the bent portions 52 included in each fixing jig 50 is bent in a different direction with respect to the bent portions 52 included in the other fixing jigs 50. Thereby, the 1st part 21 (arrangement member 20) can be more firmly fixed with the outstanding position accuracy by fixing jig 50. FIG.

  In the present embodiment, the case where the main body 51 has a disk shape as shown in FIGS. 3 to 5 has been described. However, the main body 51 only needs to have a flat plate shape. The visual shape may be a polygon such as a triangle, a quadrangle, or a pentagon.

  Further, as described above, in addition to the case where the entire fixing jig 50 is configured with a metal material as a main material, the entire fixing jig 50 may be configured with a thermoplastic resin material as a main material. In this case, the bending portion 52 can be bent by pressing a heated iron while the bending portion 52 is inserted into the through hole 25 of the arrangement member 20.
