Description

Technical Field

[0001] The present invention relates to a construction method for balcony renovation.

Background Art

[0002] Generally, structures such as houses are constructed for the purpose of continuous living over a long period, but aging deterioration is inevitable. In particular, parts located outdoors such as balconies and roofs are more significantly affected by sunlight and wind and rain, and thus experience more severe aging deterioration than other parts. Therefore, when continuing to live in the same house, renovation of these parts becomes necessary after a certain period of time has passed.

[0003] For example, Patent Document 1 discloses a method for renovating a balcony floor. The balcony floor renovated by this renovation method has a synthetic resin dish-shaped floor material placed as a new floor material on top of the synthetic resin decking material of the existing balcony floor, and the decking material and the dish-shaped floor material are integrated via an adhesive. According to this renovation method, since it is configured to directly place a new floor material on top of the decking material of the existing balcony floor and integrate the decking material and the new floor material, it is possible to renovate the balcony floor at low cost without taking much time and effort and without incurring construction costs.

Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in a balcony, the floor material is not a single member but is composed of a plurality of members. Therefore, if there are variations in the dimensions between each member, the cumulative dimensional error when combining a plurality of members becomes large, and damage such as water leakage is likely to occur in the entire balcony.

[0006] Therefore, the present invention aims to provide a construction method for balcony renovation that can absorb dimensional errors that may occur between components with a simple configuration. [Means for solving the problem]

[0007] To address the above problems, the present invention provides a construction method for balcony renovation, comprising: a sealing step of sealing a gap formed between a pair of pre-installed base materials with a long sealing member; and a fixing step of placing a pair of surface materials on the base materials with the sealing member in between, bending the sealing member side of the surface materials to form a pair of rising portions, and fixing the pair of rising portions to the sealing member, wherein in the fixing step, the pair of rising portions are fixed to the sealing member according to the distance between the base end of the rising portion which is the starting point and the sealing member, or a dimensional adjustment member is placed in the space formed between at least one of the pair of rising portions and the sealing member, and the rising portion is fixed to the sealing member via the dimensional adjustment member.

[0008] In the fixing step, it is desirable to arrange multiple dimensional adjustment members at intervals along the direction in which the sealing member extends.

[0009] Furthermore, it is desirable to have a waterproofing step that covers the sealing member and the pair of rising portions with a waterproof structure that extends along the direction in which the sealing member extends and is formed in a concave shape in cross-section. [Effects of the Invention]

[0010] In the construction method for balcony renovation according to the present invention, in the fixing step of fixing a pair of rising sections to a sealing member, the pair of rising sections are fixed to the sealing member according to the distance between the base end of the rising section, which is the starting point of the rising section, and the sealing member, or a dimensional adjustment member is placed in the space formed between at least one of the pair of rising sections and the sealing member, and the rising section is fixed to the sealing member via the dimensional adjustment member.

[0011] Therefore, if the distance between the base end and the sealing member exceeds a certain level, a dimensional adjustment member is placed between the rising portion and the sealing member to improve the adhesion between the rising portion and the sealing member via the dimensional adjustment member. Consequently, even if a dimensional error occurs between the surface material and the sealing member after installation, the dimensional error can be absorbed with a simple configuration.

[0012] In the fixing process, multiple dimensional adjustment members are placed at intervals along the direction in which the sealing member extends. This makes it possible to align the position where the rising portion is fixed to the sealing member with the position where the dimensional adjustment members are placed.

[0013] Furthermore, the process includes a waterproofing step in which a waterproof structure extending along the direction in which the sealing member extends and formed in a concave shape in cross-section covers the sealing member and a pair of rising portions. This allows the sealing member to cover the sealed portion from above, thereby improving the waterproofing effect. [Brief explanation of the drawing]

[0014] [Figure 1] This is a floor plan of a building to which the construction method for balcony renovation according to an embodiment of the present invention is applied. [Figure 2] This is a cross-sectional view along line AA in Figure 1. [Figure 3] This figure shows a state where no gap is formed between the base end and the sealing member. [Figure 4] This figure shows an example where the distance between the base end and the sealing member is less than a predetermined value. [Figure 5] This figure shows an example where the distance between the base end and the sealing member is greater than or equal to a predetermined value. [Modes for carrying out the invention]

[0015] Hereinafter, an inner wall installation method according to an embodiment of the present invention will be described with reference to the drawings.

[0016] FIG. 1 is a plan view of a building (unit building) including a balcony, and FIG. 2 is a cross-sectional view taken along line A-A of FIG. 1.

[0017] As shown in FIG. 1, the building 100 has a balcony 1. The building 100 is, for example, a unit building. A unit building is a building that can be constructed in a short period of time by prefabricating box-shaped (rectangular parallelepiped) building units at a factory, transporting them to a construction site, and combining and installing them at the construction site.

[0018] The balcony 1 is an accessory equipment of the building 100 installed outside the main body of the building 100. The balcony 1 is arranged at a relatively high position in the building 100 and is installed so as to project outward from the main body of the building 100.

[0019] As shown in FIG. 2, the balcony 1 includes a pair of field boards 10 as a base material, a sealing member 11 for sealing a gap W formed between the pair of field boards 10, a groove board 12 as a surface material covering the field boards 10, a fixing member 13 for fixing the groove board 12 to the sealing member 11, a spacer 20 provided between the groove board 12 and the sealing member 11, a lower waterproof member 31 covering the sealing member 11 and the groove board 12, and an upper waterproof member 32 covering the lower waterproof member 31.

[0020] Since the balcony 1 is located outdoors and is likely to deteriorate due to exposure to wind and rain, it needs to be repaired after a certain period of time. When repairing the balcony 1, various members including the field boards 10, the sealing member 11, and the groove board 12 are replaced with new members. Hereinafter, each step in the repair of the balcony 1 will be described.

[0021] <Sealing process> When repairing the balcony 1, first, a pair of field boards 10 are arranged. The field boards 10 are a part that forms the foundation of the balcony 1 and are wooden members formed in a flat plate shape. The pair of field boards 10 may be arranged without a gap or may be arranged with a gap. In the following, the description will be made on the premise that a gap W occurs between the pair of field boards 10.

[0022] In the sealing step, a gap W formed between a pair of field plates 10 installed in advance is sealed with a long sealing member 11. The sealing member 11 is a wooden bar extending along the direction in which the gap W extends (the depth direction of the drawing sheet), and has a width larger than the gap W.

[0023] <Fixing step> In the fixing step, a pair of groove plates 12 are arranged on the field plates 10 with the sealing member 11 interposed therebetween, the sides of the groove plates 12 on the sealing member 11 side are bent to form a pair of rising portions 12b, and the pair of rising portions 12b are fixed to the sealing member 11.

[0024] The groove plate 12 is formed of a thin steel plate having water resistance, and includes a flat plate portion 12a covering the surface of the field plate 10 and a rising portion 12b rising from one end side of the flat plate portion 12a. The groove plate 12 is fixed to the sealing member 11 by fixing the rising portion 12b to the sealing member 11 with a fixing member 13 such as a screw.

[0025] Furthermore, in the fixing step, depending on the distance between the base end portion 12c, which is the starting point of the rising portion 12b, and the sealing member 11, the pair of rising portions 12b are fixed to the sealing member 11, or a spacer 20 is arranged in a space formed in at least one of the pair of rising portions 12b and the sealing member 11, and the rising portion 12b is fixed to the sealing member 11 via the spacer 20.

[0026] Here, FIG. 2 shows an example in which the groove plate 12 is fixed to the sealing member 11 with a fixing member 13 penetrating the upper side of the spacer 20. However, depending on the distance between the base end portion 12c and the sealing member 11, it is also possible to directly fix the rising portion 12b to the sealing member 11 without using the spacer 20.

[0027] Therefore, the cases in which a spacer 20 is provided between the rising portion 12b and the sealing member 11 and in which it is not provided will be explained in Figures 3 to 5. In Figures 3 to 5, the relationship between the groove plate and the sealing member will be mainly explained, and the illustration and detailed explanation of other components will be omitted as appropriate.

[0028] Figure 3 shows a state in which no gap is formed between the base end portion 12c and the sealing member 11. In other words, the rising portion 12b is bent almost straight up from the base end portion 12c, and the rising angle of the rising portion 12b is approximately 90 degrees. The reason why there is almost no gap formed between the rising portion 12b and the sealing member 11 is that there is almost no dimensional error between the sealing member 11 and the groove plate 12.

[0029] Under these conditions, the rising portion 12b can be positioned to be in close contact with the sealing member 11. Therefore, the rising portion 12b is directly fixed to the sealing member 11 with fixing members 13 such as screws.

[0030] Figure 4 shows an example where the distance D1 between the base portion 12c and the sealing member 11 is less than a predetermined value, and a space S is formed between the rising portion 12b and the sealing member 11. In other words, the rising angle X of the rising portion 12b is, for example, 75 degrees or more and 90 degrees or less. The reason why a certain amount of space S is formed between the rising portion 12b and the sealing member 11 is that a certain dimensional error occurred between the sealing member 11 and the groove plate 12 during construction. The predetermined value here is, for example, about 6 mm, but it is not limited to this value.

[0031] Under these conditions, although it is not possible to position the rising portion 12b so that it is in close contact with the sealing member 11, a certain degree of strength can be ensured by directly fixing the rising portion 12b to the sealing member 11 with fixing members 13 such as screws. Therefore, the rising portion 12b is fixed to the sealing member 11 without providing a spacer 20 between the rising portion 12b and the sealing member 11.

[0032] Figure 5 shows an example where the distance D2 between the base portion 12c and the sealing member 11 is greater than or equal to a predetermined value, and a space S is formed between the rising portion 12b and the sealing member 11. In other words, the rising angle Y of the rising portion 12b, shown by the dashed line, is 74 degrees or less. The reason why a certain amount of space S is formed between the rising portion 12b and the sealing member 11 is that a dimensional error greater than expected occurred between the sealing member 11 and the groove plate 12 during construction.

[0033] Under these conditions, it is not possible to position the rising portion 12b so that it is in close contact with the sealing member 11, and it is difficult to directly fix the rising portion 12b to the sealing member 11 with fixing members 13 such as screws. Therefore, a spacer 20 is provided between the rising portion 12b and the sealing member 11, and the rising angle of the rising portion 12b is set to 90 degrees or an angle close to it, thereby fixing the rising portion 12b to the sealing member 11 via the spacer 20.

[0034] The spacers 20 may be provided continuously along the direction in which the sealing member 11 extends, or they may be arranged at intervals. If the spacers 20 are arranged at intervals, the rising portion 12b can be fixed to the sealing member 11 by the fixing member 13 at the locations where the spacers 20 are provided.

[0035] The material of the spacer 20 is not particularly limited, but it can be made up of an elastic material such as rubber or resin. Furthermore, the thickness of the spacer 20 is not particularly limited and can be appropriately changed according to the distance between the sealing member 11 and the base end 12c. This configuration allows for more flexible absorption of dimensional errors.

[0036] <Waterproofing process> After the fixing process is completed, there may be a waterproofing step in which the sealing member 11 and the pair of rising portions 12b are covered by a waterproof structure that extends along the direction in which the sealing member 11 extends and is formed in a concave shape in cross-section. The waterproof structure includes a lower waterproof member 31 and an upper waterproof member 32.

[0037] The lower waterproofing member 31 is a flexible waterproofing member that can be elastically deformed. As shown in Figure 2, the lower waterproofing member 31 is positioned above the sealing member 11, sandwiching the rising portion 12b. The inner surface of the lower waterproofing member 31 is bonded to the sealing member 11, and the outer surface of the lower waterproofing member 31 is bonded to the rising portion 12b.

[0038] The upper waterproofing member 32 is a waterproofing member formed in a concave shape in cross-section, with an opening on the downward side. As shown in Figure 2, the upper waterproofing member 32 is arranged to surround the lower waterproofing member 31. The upper waterproofing member 32 is formed of, for example, a SUS steel plate.

[0039] As described above, in the construction method for balcony renovation according to the embodiment, in the fixing step of fixing the pair of rising portions 12b to the sealing member 11, the pair of rising portions 12b are fixed to the sealing member 11 according to the distance between the base end portion 12c which is the starting point of the rising portion 12b and the sealing member 11, or a dimensional adjustment member (spacer) 20 is placed in the space formed between the pair of rising portions 12b and the sealing member 11, and the rising portion 12b is fixed to the sealing member 11 via the spacer 20.

[0040] Therefore, if the distance between the base portion 12c and the sealing member 11 is greater than a certain amount, a spacer 20 is placed between the rising portion 12b and the sealing member 11 to improve the adhesion between the rising portion 12b and the sealing member 11 via the spacer 20. Thus, even if a dimensional error occurs between the surface material and the sealing member 11 after installation, the dimensional error can be absorbed with a simple configuration.

[0041] In the fixing process, multiple spacers 20 are placed at intervals along the direction in which the sealing member 11 extends. This makes it possible to align the position where the rising portion 12b is fixed to the sealing member 11 with the position where the spacers 20 are placed.

[0042] Furthermore, the device includes a waterproofing step in which a waterproof structure extending along the direction in which the sealing member 11 extends and formed in a concave shape in cross-section covers the sealing member 11 and a pair of rising portions 12b. This allows the sealing member 11 to cover the sealed portion from above, thereby improving the waterproofing effect.

[0043] While embodiments of the present invention have been described in detail above with reference to the drawings, the specific configuration is not limited to these embodiments, and any design modifications that do not depart from the spirit of the present invention are included in the present invention.

[0044] In the above embodiment, an example was shown in which spacers 20 are provided on both sides of the sealing member 11. Depending on the distance between the base end portion 12c and the sealing member 11, the spacers 20 may be provided on only one side of the sealing member 11. [Explanation of Symbols]
