The building sheet joint structure of the present invention will be described below with reference to the drawings. The present invention is not limited to the following embodiments.

The outline of the joint structure of the building sheet of the present invention will be described with reference to FIG. The joint structure of the present invention is a structure relating to a joint between the ends of adjacent building sheets 3-1 and 3-2 when a plurality of building sheets 3 are laid and fixed on a substantially flat base 1, and the joint is formed. It is provided with a joint member 2 to be joined to the building sheet 3 along the above. The upper surface of the joint structure of the present invention has no step, and the joint portion is formed to have a height slightly higher than the peripheral portion as compared with the peripheral portion. As a result, there is no step even in places where steps are likely to occur, such as the joints between the sheet edges, and the structure has a gentle slope from there to the outside around the joints, eliminating the problem of water collecting at the joints. To do.

Here, each member constituting the joint structure of the building sheet of the present invention will be described.

<Base>
The base 1 can be used without particular limitation, but it is applied to concrete bases such as rooftops, roofs, balconies, terraces of buildings such as buildings, condominiums, and detached houses, lightweight foam concrete bases, metal bases, wood bases, and inorganic boards. ..

Examples of the inorganic board include gypsum board, cement board, calcium silicate board, and resin reinforced board. However, in order to have less warpage and excellent dimensional stability, a resin reinforced board in which the inorganic material is solidified and reinforced with a thermosetting resin is more suitable. preferable.
Further, the surface of the base 1 may be treated with various treatment agents or the like, for example, a base adjusting material for smoothing the surface is applied, or a waterproof layer is formed by waterproofing the coating film or the like. It may have been done.

<Joint members>
The joint member 2 is a member that is joined to the building sheet along the joint between the ends of the building sheet 3, and the ends of the building sheet 3 are joined to each other especially in a place where watertightness of the joint is required. It is preferable that the joint members 2 are continuously joined along the joints of the joints, and a band-shaped joint member 2 is preferably used. The joint member 2 is formed to be thin from the portion corresponding to the joint to the end portion B parallel to the portion A corresponding to the joint. Further, the joint member 2 may be a single member or may be composed of a plurality of members.

FIG. 2 shows an example of the cross-sectional shape of the joint member 2 in the width direction (direction perpendicular to the joint). The details of the shape of the joint member 2 will be described below with reference to FIG.

The joint member 2-1 in FIG. 2 has a substantially isosceles triangle cross section, A is a portion corresponding to the joint of the building sheet 3, and the bottom surface connecting the ends B1 and B2 on both sides is arranged on the base side. It becomes a surface. The joint member 2-1 is formed so that the thickness of the end portions B (B1, B2) is thinner than the thickness AA'of the portion A corresponding to the joint.

The cross section may be trapezoidal as in the joint member 2-2. In this case, it is preferable that the joint of the building sheet 3 corresponds to a substantially central portion on the surface connecting the end portions C1 and C2. The joint member 2-2 is a surface on which the bottom surface connecting the ends B1 and B2 on both sides is arranged on the base side. The joint member 2-2 is formed so that the thickness of the end portions B (B1, B2) is thinner than the thickness AA'of the portion A corresponding to the joint.

The shape may be a combination of two right triangles with a cross section such as the joint member 2-3. In this case, the joint members 2-3 have two portions A1 and A2 corresponding to the joints of the building sheets 3. The bottom surface connecting the portion A2 corresponding to the joint and the end portion B2 on one side is the surface to be arranged on the base side. The joint members 2-3 are formed so that the thickness of the end portion B (B1, B2) is thinner than the thickness AA'(A1A'1, A2A'2) of the portion A (A1, A2) corresponding to the joint.

The joint member 2-4 has a substantially right-angled triangular cross section, A is a portion corresponding to the joint of the building sheet 3, and the bottom surface connecting one end B and A'is arranged on the base side. It becomes a face. The joint member 2-4 is formed so that the thickness of the end portion B is thinner than the thickness AA'of the portion A corresponding to the joint.

It is preferable that the joint member 2 is as thin as possible because the joints of the building sheets 3 are smoother, but if it is too thin, the joint strength of the joints may decrease. Therefore, the thickness of the portion of the joint member 2 corresponding to the joint of the building sheet 3 is preferably 0.1 to 10.0 mm, more preferably 0.5 to 5.0 mm. The thickness of the joint member 2 is preferably 0.01 to 1.0 mm, more preferably 0.05 to 0.5 mm.

The joint member 2 preferably has an inclination from the portion A corresponding to the joint of the building sheet 3 to the end portion B, and the joint member 2 is a portion corresponding to the joint of the building sheet 3. It is preferable that the whole is inclined from A to the end B.
For example, in the case of the joint member 2-1 of FIG. 2, the portion A extending from the portion A corresponding to the joint of the building sheet 3 to the end B1 or the end B2 has an inclination, and the portion A corresponding to the joint. It is generally inclined from the end B1 or the end B2. In the case of the joint member 2-2, the portion extending from the portion A corresponding to the joint of the building sheet 3 to the end portion B1 or the end portion B2 has a partial inclination. Since the joint member 2 has such an inclination, there is an effect that water is less likely to collect at the joint of the building sheets 3. Looking at the joint members 2-1 and 2-2, the portion corresponding to the joint is compared with the joint member 2-2 which has a partial inclination in the portion extending from the portion A to the end B corresponding to the joint. The joint member 2-1 having an overall inclination from A to the end B is more effective in preventing water from accumulating.

By providing the joint member 2 with an inclination in this way, the thickness of the portion A corresponding to the joint can be increased. As a result, the joint strength of the joint (joint) portion between the building sheet 3-1 and the building sheet 3-2 can be increased. Here, when the building sheets 3-1 and the building sheets 3-2 are joined by abutting the ends thereof (for example, FIG. 1), the end faces of the building sheets 3 may not be sufficiently joined. However, a joint member 2 is arranged at the joint portion (joint joint), and the front surface of the joint member 2 and the back surface of the building sheet 3-1 and the building sheet 3-2 are joined. Therefore, even when stress acts on the joint portion (joint joint), the joint member 2 can counter the stress. In this case, it is preferable to form the portion A corresponding to the joint thickly because the resistance to this stress becomes stronger. However, if the thickness of the end portion B is also large, the step becomes large and a puddle is likely to occur. On the other hand, by forming the end portion B thinly and providing the joint member 2 with an inclination, it is possible to avoid a step and prevent a puddle from forming, and the thickness of the portion A corresponding to the joint is excellent, so that the joint strength is also excellent. It will be.

The inclination of the joint member 2 from the portion A corresponding to the joint to the end portion B is preferably 1/200 to 1/5, more preferably 1/100 to 1/20.
If the inclination is too small, it is necessary to increase the width in order to secure the thickness, and the joint surface with the building sheet becomes wide and the workability deteriorates.
If the inclination is too large, when it is joined to the building sheet 3, it will not be flat when viewed from the base surface.
Further, the direction of inclination is preferably toward a direction substantially orthogonal to the linear joint which is the joint between the ends of the building sheet 3.

The joint members 2-1 and 2-2 of FIG. 2 are mainly used in the case of forming a joint structure in which the ends of the building sheet 3 are abutted against each other and joined to each other, and the joints are formed on the base 1 as shown in FIG. When the building members 2-1 are arranged and the joints of the building sheets 3-1 and 3-2 are abutted against each other to form a joint structure, the parts A corresponding to the joints of the building sheets 3 are formed. A mark can be provided. FIG. 3 shows a modified example of the joint member 2-1. The joint member 2-1a in FIG. 3 is an example in which a recess is formed as a mark in the portion A corresponding to the joint, and the joint member 2-1b is an example in which a linear drawing is performed as a mark. The mark is not limited to this, and may be, for example, a convex line or a drawing such as a broken line or a dotted line. By providing such a mark, the joint of the building sheet 3 can be accurately matched with the portion A corresponding to the joint of the joint member 2, thereby preventing the joint from floating or forming a puddle at the joint. The effect is enhanced. Further, when the recess is formed as a mark, a welding rod, a sealer, or the like can be inserted into the recess as a joint treatment agent for the joint, and the effect of improving the finish of the end treatment can be obtained.

As the joint member 2, a synthetic resin, a metal plate, or the like can be selected in a timely manner, and these can be combined and used.
When the joint member 2 used in the present invention is made of synthetic resin, it is an olefin resin such as polyethylene or polypropylene, an ethylene-vinyl acetate copolymer resin, an ethylene- (meth) acrylic acid ester, a polyvinyl chloride, or a polyvinyl chloride resin. , Chlorinated polyethylene, acrylic resin, styrene resin, styrene butadiene rubber, acrylonitrile butadiene rubber and the like, and these two or more kinds of resins may be used in combination.

Examples of the polyvinyl chloride resin used for the joint member 2 include a polyvinyl chloride resin which is a vinyl chloride homopolymer, a copolymer of vinyl chloride and vinyl acetate, ethylene, (meth) acrylic acid ester, vinylidene chloride, and the like. Etc. can be used, and polyvinyl chloride resin is preferable from the viewpoint of economy and processability.

Further, the joint member 2 can be used in either a single layer or a plurality of layers, and a base material can be laminated. As the base material, natural fibers such as cotton and linen, synthetic fibers such as polyester, polyethylene and acrylic, woven fabrics of glass fibers and non-woven fabrics can be used. Among them, polyester non-woven fabric, glass non-woven fabric, and glass woven fabric are preferable from the viewpoint of dimensional stability and workability.

Each layer of the joint member 2 may be composed of layers having different compositions, or may be composed of the same composition. Further, the base material may be laminated on the lowest layer or may be laminated between the layers.

When a synthetic resin is used for the joint member 2, a plasticizer, an antioxidant, a lubricant, a stabilizer, an ultraviolet absorber, a light stabilizer, a processing aid, a filler, a flame retardant, a pigment, etc. are added as necessary. Can be added.

Examples of the plasticizer include phthalic acid-based plasticizers such as DOP, DINP, DUP, and DOTP, adipic acid-based plasticizers such as DOA, DINA, and DIDA, polyester-based plasticizers, trimellitic acid-based plasticizers, TCP, TXP, and the like. Phthalic acid ester-based plasticizers, epoxy-based plasticizers such as epoxidized soybean oil, cyclohexane-based plasticizers such as DINCH, and the like can be used. Of these, phthalic acid-based plasticizers such as DOP and DINP are preferable from the viewpoints of weather resistance, durability, plasticization efficiency, compatibility, and processability.

For example, when a polyvinyl chloride resin is used as the synthetic resin, the amount of the plasticizer added is preferably 10 parts by weight to 100 parts by weight, preferably 30 to 100 parts by weight, based on 100 parts by weight of the polyvinyl chloride resin from the viewpoint of processability and flexibility. 70 parts by weight is more preferable.

Further, as the filler, an inorganic filler such as calcium carbonate, magnesium carbonate, aluminum hydroxide, magnesium hydroxide, talc, carion, mica, magnesium silicate can be used. For example, when a polyvinyl chloride resin is used as the synthetic resin, the amount of the filler added is preferably 5 to 200 parts by weight, preferably 50 to 200 parts by weight, based on 100 parts by weight of polyvinyl chloride from the viewpoints of economy, processability, and flexibility. 150 parts is more preferable.

<Building sheet>
As the building sheet 3 used in the present invention, a building sheet made of synthetic resin such as vinyl chloride-based, olefin-based, acrylic-based, and rubber-based can be used. Vinyl chloride-based building sheets are preferable from the viewpoints of workability, weldability between sheets, and adhesion to building sheet fixing brackets.
As the thickness of the building sheet 3, a sheet of 0.5 to 5.0 mm can be used, and 1.0 to 2.5 mm is preferable from the viewpoint of safety of waterproof performance.

Further, the building sheet 3 can be used in either a single layer or a plurality of layers. Further, in the case of a plurality of layers, the base materials can be laminated. As the base material, natural fibers such as cotton and linen, synthetic fibers such as polyester, polyethylene and acrylic, woven fabrics of glass fibers and non-woven fabrics can be used. Among them, polyester non-woven fabric, glass non-woven fabric, and glass woven fabric are preferable from the viewpoint of dimensional stability and workability.

When the building sheet 3 has a plurality of layers, each layer may be composed of layers having different compositions, or may be composed of the same composition. Further, the base material may be laminated on the lowest layer or may be laminated between the layers.
The top layer and the bottom layer are thermoplastic resin layers from the viewpoint that solvent welding and hot air welding can be performed when joining the building sheet 3 and the joint member 2 or when joining the building sheets 3 in layers. It is preferably configured. For example, in the case of a polyvinyl chloride-based waterproof sheet, one in which the uppermost layer and the lowermost layer are made of polyvinyl chloride resin and the base material is laminated in the middle can be preferably used. When the building sheet 3 is a polyvinyl chloride-based sheet, the joint member 2 is also preferably made of a polyvinyl chloride-based resin.

Since the building sheet 3 exhibits the purpose of obtaining anti-slip properties during walking and design, the surface may be provided with regular or irregular irregularities, and the surface may be provided with a design layer such as printing. It may have been printed. Such a building sheet 3 is suitably used in a place such as an open corridor such as an apartment or a veranda.

<Joint structure>
The joint structure of the present invention will be specifically described with reference to the drawings.

1 and 4 to 9 show aspects of the joint structure of the present invention. These are roughly classified according to how the building sheets 3 are connected. As shown in FIGS. 1, 4, and 5, the ends of the building sheets 3 are abutted and joined (classification i), and as shown in FIG. 6, the building is constructed. It can be classified into those in which the ends of the building sheets 3 are joined to face each other (classification ii) and those in which the ends of the building sheets 3 are overlapped and joined as shown in FIGS. 7 to 9 (classification iii).

The joint members 2-1 and 2-2 of FIG. 2 are preferably used for the joint structure of the classification i.
In the joint structure of FIG. 1, the joint member 2-1 is used, the joint member 2-1 is fixed to the base 1, and the end portions 3-1a of the building sheets 3-1 and 3-2, The back surface of the edge portion of the building sheets 3-1 and 3-2 and the front surface of the joint member 2-1 are fixed in a state where 3-2a is abutted. Further, in this structure, since the joints of the building sheets 3-1 and 3-2 are formed at the apex of the cross section of the joint member 2-1 so that no step is generated, a substantially flat joint structure can be obtained. Further, since the joint member 2-1 has no flat portion from the portion corresponding to the joint of the building sheet 3 to the end and is inclined as a whole, water does not collect at the joint and is drained. Further, in this case, since the building sheets 3-1 and 3-2 come to the outermost surface, the design of the building sheet 3 is not impaired, so that the building sheet 3-1 and 3-2 are preferably used in a place such as an open corridor of an apartment or a floor of a balcony. Therefore, it is not necessary to impart the same weather resistance as the building sheet 3 to the joint member 2 even when used outdoors.

As shown in FIG. 4, the joint member 2-1 may be arranged on the building sheet 3. In this case, after fixing the ends 3-1a and 3-2a of the building sheets 3-1 and 3-2 to the base in an adjacent state, the joint member 2-1 can be fixed along the joint. Good sex.

In the joint structure of FIG. 5, joint members 2-2 having a trapezoidal cross section are used, and the ends (3-1a, 3-2b) of the building sheets 3-1 and 3-2 are jointed. By joining on the flat part of the joint member 2-2, the edge portions of the building sheets 3-1 and 3-2 can be joined to the joint member 2-2 in a state parallel to the base 1. Even if the inclined portion of the joint member 2-2 has a large inclination, the risk of opening the joint between the end portions of the building sheet 3 is considerably lower than that of the joint member 2-1 (FIG. 1).

The joint members 2-3 of FIG. 2 are preferably used for the joint structure of the classification ii.
In the joint structure of FIG. 6, the ends (3-1a, 3-2b) of the building sheets 3-1 and 3-2 are joined to the joint members 2-3 in a state of facing each other without abutting. The end portion 3-1a of the joint member 3-1 is in contact with A2 of the joint member 2-3, and the end portion 3-2a of the building sheet 3-2 is in contact with A1 of the joint member 2-3. .. Since the ends of the building sheets 3-1 and 3-2 are joined to the joint members 2-3 in a state of facing each other without abutting, in the case of abutting of classification i when laying the building sheet 3 There is an advantage that it is easier to adjust the laying position compared to. To form this joint structure, the building sheet 3-1 is first fixed to the base, and then the joint members 2-3 are provided along the end 3-1a of the building sheet 3-1 for construction. The sheets 3-2 may be joined, or the joint members 2-3 may be fixed to the base 1 first, and then joined to the building sheets 3-1 and 3-2.

The joint member 2-4 of FIG. 2 is preferably used for the joint structure of the classification iii.
In the joint structure of FIGS. 7 to 9, the ends of the building sheets 3-1 and 3-2 are overlapped and joined, and the ends of the building sheet 3-1 and the ends of the building sheet 3-2 are joined. The joint member 2-4 (2-4') is in contact with both or one of the portions 3-2a. As shown in FIG. 7, the joint member 2 may be composed of a plurality of members with respect to the joint structure, and the joint member 2 in FIG. 7 is a composite of the joint member 2-4 and the joint member 2-4'. In this case, it can be said that the joint member 2 is formed to be thinner at both ends than the portion corresponding to the joint.
The joint structure of the classification iii tends to have a slightly poorer joint smoothness than the structures of the classification i and the classification ii, but it is more excellent in watertightness because the edge portions of the building sheet 3 are overlapped and joined. It is a structure and can be suitably used for a waterproof structure for rooftops and roofs.

When fixing the joint member 2 to the base 1, in addition to adhering with various adhesives, adhesives, double-sided tape, etc., a machine using a fixing plate such as a fixing disc and a fixing member such as a screw. It can be fixed. Further, the building sheet 3 can be fixed to the base 1 by various adhesives, adhesives, double-sided tape, or mechanical fixing using a fixing plate such as a fixing disc and a fixing member such as a screw. The joint member 2 and the building sheet 3 can be fixed by bonding with various adhesives, adhesives, double-sided tape, liquid welding with a solvent, or heat welding with heat.

When the building sheet 3 is fixed to the base 1 by the mechanical fixing method, for example, a resin coating fixing metal disk in which the surface of the metal plate is coated with a resin layer is placed on the base 1, and a resin is used from above. The metal disk for fixing the coating is fixed to the base 1, the building sheet 3 is laid on the base 1, and the resin layer of the metal disk for fixing the resin coating and the back surface of the building sheet 3 are heated by a hot air welder, a solvent, or induced heating. It can be welded and joined. In this case, a strip-shaped resin-coated steel sheet can also be used.

In the joint structure of the present invention, the joint 8 between the building sheets 3 and the joint 9 between the joint member 2 and the building sheet 3 can be joint-treated with various joint treatment agents. As the joint treatment agent, a synthetic resin-based liquid sealer, a sealing material, a welding rod, or the like can be used. By applying joint treatment, it is possible to prevent the joints from opening or peeling off after construction, and the watertightness of the joints is also improved.

The joint structure of the present invention may have an inclination from a substantially central portion (joint center D) of the joint of the building sheet 3 shown in FIG. 1 to an end portion of the joint structure (joint structure end portion E). It is preferable that the entire joint is inclined from the center D of the joint to the end portion E of the joint structure. Since the joint structure has such an inclination, there is an effect that water is less likely to collect at the joint of the building sheet 3, and the effect is that the entire joint structure is inclined from the joint center D to the joint structure end E. Is improved.
The inclination from the joint center D to the joint structure end E is preferably 1/200 to 1/5, more preferably 1/100 to 1/20.

The embodiment of the present invention can also be used when using a groundwork having an inclination such as a veranda of a house or the like. In this case, even if there is a joint of the building sheet 3, the joint can be formed without a step by using the joint member 2, and drainage can be performed without forming a puddle. As for the inclination of the base, a concrete base or the like may be inclined, or a heat insulating material or the like having a slope may be laid on the concrete base or the like.

Further, in the construction structure of the building sheet 3 using the joint structure of the present invention, another layer can be provided between the base 1 and the building sheet 3 and the joint member 2, for example, a heat insulating board or an inorganic board. Can be provided.

Examples of the inorganic board include gypsum board, cement board, calcium silicate board, resin reinforced board, etc., but in order to have less warpage and excellent dimensional stability, a resin reinforced board made by solidifying and strengthening an inorganic material with a thermosetting resin. Is more preferable.

As the heat insulating board, a heat insulating material such as polystyrene foam, rigid urethane foam, or phenol foam can be used, and in consideration of strength, a heat insulating material in which kraft paper or aluminum foil is laminated on both sides is preferable. The thickness of the heat insulating material is 20, 25, 50, 75, 100 mm, etc., and is set according to each specification. For the vertical and horizontal dimensions, standard products (910 mm x 1820 mm, 910 mm x 910 mm, 30 mm x 50 mm, etc.) are cut and used according to the construction site. The thickness of the heat insulating material is set according to each specification, but when a thick heat insulating material is required, one thick heat insulating material should be used in consideration of the trouble of carrying in, drilling, and warping. It is preferable to use a plurality of thin sheets in a stack rather than using the above. In addition, if it is necessary to take a slope, a heat insulating board with a slope can be used.

The method of fixing the inorganic board or the heat insulating board to the base 1 is not particularly limited, but a fixing plate such as a fixing disk is placed on the inorganic board or the heat insulating board and fixed to the base 1 with a fixing member such as a screw from above. There is a way.

Fixing plates such as fixing disks used for fixing the building sheet 3 to the base 1 and fixing the inorganic board or the heat insulating board to the base 1 are made of resin or metal coated with a resin layer. Can be used. As the material of the steel plate that constitutes the metal fixing disc, a steel plate that does not easily rust even in a humid condition such as a stainless steel plate or a steel plate that has been subjected to rust-preventive treatment such as zinc / aluminum / magnesium plating or zinc plating is preferable. used.
