[Technical field of invention]

 The present invention relates to a veranda member used when a waterproof layer is laid on a veranda of a building such as a steel frame building, and a waterproof structure of a building veranda that waterproofs the veranda using the veranda member.

[0002]

[Technical background of the device]

 A waterproof layer (waterproof sheet) is laid on the veranda of buildings such as steel-framed buildings to prevent water from entering the building. In addition, there are some verandas of buildings that have a balcony wall that is not constructed of pipes, but is constructed as a wall so as to have an integral view with the exterior wall. Since the height of the wall is generally 100 cm or more, when constructing the balcony wall, a frame structure such as light steel frame may be embedded inside the balcony wall.

For example, in a veranda structure of a building as shown in FIG. 5, a steel frame (not shown) is projected from a steel frame beam 1 of a building frame, and a steel frame beam 2 for a veranda is fixed to the tip of the projecting steel frame. There is. On this steel beam 2, there is a frame structure composed of a pillar member 3 which extends vertically and is made of lightweight steel frame, and horizontal members 4 and 5 which are fixed to the upper and lower portions of the pillar member 3 by welding or the like and are horizontally made of lightweight steel frame and the like. It is fixed. Lath sheet upholstery 6 and mortar 7 are laid on the outdoor side of the frame structure, and lining members 8 and mortar 9 are laid on the indoor side of the frame structure. Configured. On the other hand, on the floor surface of the balcony, a floor member 10 such as a deck plate is arranged between the steel beams 1 and 2, and lightweight concrete 11 is cast on the floor member 10.

The waterproof sheet 12 is laid on the lightweight concrete 11, the end 12a of the waterproof sheet is lifted up to the lower part of the balcony wall, and a lining member is pierced by a nail 14 or the like via a pad plate 13. It is attached to 8. A waterproof mortar 15 and the like are laid all over the waterproof sheet 12. Further, a corner cant 16 is laid at the corner between the lightweight concrete 11 and the lining member 8 so that the waterproof sheet 12 will not be extremely bent at the rising portion of the balcony wall. As a result, extreme bending of the waterproof sheet 12 is prevented and water leakage from this corner is prevented.

However, in the structure of the veranda as described above, the waterproof sheet end portion 12a is attached to the lining member 8 by the nail 14 or the like. It is a relatively thin plate such as a plate made of synthetic resin or a plate made of synthetic resin. Therefore, the nail 14 cannot be firmly fixed to the lining member 8 and the waterproof sheet end portion 12a cannot be reliably attached. As a result, water leakage may occur. .. In FIG. 5, it seems that a fixing member such as a nail 14 may be attached to the pillar member 3, but the pillar members 3 are arranged at predetermined intervals, and are arranged all over the veranda. However, a fixing member such as a nail 14 cannot be attached to the column member 3.

Further, although the corner cant 16 is laid, the laying of the corner cant 16 is cumbersome for the operator, and the purpose of recent on-site construction is to reduce the work man-hours at the site. It was contrary to.

FIG. 2 is a cross-sectional view of the building veranda according to the embodiment, and is a cross-sectional view at a location where a pillar member that constitutes the veranda exists. FIG. 3 is an exploded perspective view of the building balcony according to the embodiment. FIG. 4 is a rear perspective view of the second surrounding member of the veranda according to the embodiment.

As shown in FIGS. 1 and 2, in the present embodiment, a steel frame (not shown) is projected from the steel frame beam 1 of the building frame, and the steel frame beam 2 for a veranda is fixed to the tip of the projecting steel frame. There is. On this steel beam 2, there is a frame structure composed of a pillar member 3 which extends vertically and is made of lightweight steel frame, and horizontal members 4 and 5 which are fixed to the top and bottom of the beam by welding or the like and which are made of lightweight steel frame and extend horizontally. It is fixed. A floor member 10 such as a deck plate is provided between the steel beams 1 and 2 on the floor surface of the veranda, and a lightweight concrete 11 is cast on the floor member 10. A waterproof layer 40 is laid on the lightweight concrete 11. The waterproof layer 40 may be of various types, for example, asphalt waterproof, sheet waterproof, or the like.

As shown in FIG. 3, the first turning member 20 and the second turning member according to the present embodiment are provided inside the frame structure of the column members 3 and the horizontal members 4 and 5 that form the balcony wall. A plurality of 30 are sequentially arranged. Basically, the first and second turning members 20 and 30 are formed in substantially the same manner, but the first turning member 20 is provided at a position where the column member 3 of the frame structure does not exist. The second turning member 30 is provided at a place where the supporting column member 3 is present, and is, as it were, an accessory.

The first and second turning members 20 and 30 are raised substantially vertically from the floor plate portions 21 and 31 arranged on the deck plate 10 constituting the veranda floor surface and the floor plate portions 21 and 31, respectively. The rising portions 22 and 32 and the canted portions 23 and 33 that are inclined (for example, at 45 °) at the corner portions of the floor plate portions 21 and 31 and the rising portions 22 and 32. It should be noted that the rising portions 22 and 32 may be inclined (obtuse or acute angle) correspondingly if the balcony wall is somewhat inclined.

Notched seats 24, 34 for fastening the upper end of the waterproof layer 40 are formed in the lower portions of the rising portions 22, 32 of the first and second turning members 20, 30 on the indoor side. There is. The notched seats 24, 34 need only be recessed in the spaces corresponding to the waterproof layer 40, the backing plate 45 and the mortar layer 50, which will be described later, but can be appropriately changed. On the other hand, first recesses 25 and 35 for escaping the horizontal member 5 of the frame structure are formed on the outdoor side upper portions of the rising portions 22 and 32 of the first and second turning members 20 and 30, respectively. is there. The first recesses 25 and 35 may be formed in a shape corresponding to the shape of the horizontal member 5, and are not necessarily rectangular. Further, the upper portions of the rising portions 22 and 32 may be formed at the same height as the horizontal member 5 and the first recess may not be provided.

Further, as described above, since the second turning member 30 is arranged at the position where the supporting column member 3 exists, the second turning member 30 has a structure shown in FIG. As best shown in FIG. 2, second recesses 26 and 36 for escaping the support member 3 are formed. The second recesses 26, 36 may also be formed so as to correspond to the shape of the column member 3, and need not necessarily be rectangular.

Further, since the first turning member 20 is a normal product and the second turning member 30 is an accessory, the width dimension of the first turning member 20 may be determined as a standard product. The width dimension of the second rotating member 30 may be determined so that it surrounds the column member 3. Next, these first and second turning members 20, 30 are preferably made of the following materials.

Polystyrene foam When this polystyrene foam is used, it has the advantages of being lightweight and low in cost, but on the other hand, a non-solvent type (eg rubber type) adhesive cannot be used. However, it has the disadvantage that it takes a long time to cure and the construction period is long, and because it is a relatively hard material, it also has the problem that it is difficult to deal with uneven terrain on the balcony floor. There is also.

Polyolefin Foam Polyolefin foam, for example, foam such as polyethylene and polypropylene, is lightweight and can use a non-solvent adhesive to shorten the construction time. . Furthermore, since it is softer than polystyrene, it can cope with the unevenness of the veranda floor, and there is no problem that it is deteriorated by ultraviolet rays. However, the cost is slightly higher than polystyrene, but it is not so expensive and there is no cost problem.

Rubber foam Rubber foam has the advantage of being able to cope with uneven terrain on the veranda floor because it is relatively soft, but the expansion ratio is relatively low and the cost is high. It has the disadvantages of being heavy, hard, and hard. In summary, the polyolefin foam of (1) is most preferable, the polystyrene foam of (2) and the rubber foam of (2) are preferable. However, the materials of the first and second turning members 20 and 30 are not limited to these, and it goes without saying that various materials may be used. The expansion ratio in this case is preferably 10 to 80 times, more preferably 40 to 50 times.

Further, when molding the first and second turning members 20 and 30, it is possible to use a molding method in which they are formed as an integral body by in-mold foam molding. Further, the rotating members 20 and 30 may not be integrally molded, but may be composed of a plurality of parts that are variously disassembled, and may be assembled later as shown in the drawing. Next, the operation of the first and second turning members 20, 30 will be described.

As shown in FIGS. 1, 2, and 3, a plurality of first and second turning members 20 and 30 are arranged in parallel along the frame structure of the veranda. At this time, a second turning member 30 having a second recess 36 is provided on the outdoor side of the rising portion 32 at the position where the support member 3 is erected, and the support member is provided in the second recess 36. 3 is accommodated, and the first turning member 20 having no second recess is disposed between the second turning members 30, 30.

After that, the waterproof layer 40 is erected along the first and second turning members 20, 30, and the waterproof layer 40 together with the pad plate 45 applied to the upper end portion 40a thereof, the nail 46. The rotating members 20 and 30 are fixed by such means. When the width of the second turning member 30 having the second recess 36 is wide or narrow, the number of the first turning members 20 arranged between the second turning members 30 may be changed, or the turning members may be changed. 20 may be cut into a suitable width before use.

Further, a lath sheet tension 51, a mortar 52, etc. are laid on the outdoor side of the frame structure or the surrounding members 20, 30. Further, a lining member 53 is laid on the indoor side of the rotating members 20 and 30. The lining member 53 may be various materials such as a mortar, a decorative aluminum plate having aluminum plates on both sides and a foamed resin inside, and a ceramic water-resistant silica plate. Further, a head tree 54 is attached on the frame structure, the surrounding members 20, 30, and the like. Further, the mortar layer 50 is laid on the waterproof layer 40.

As described above, in the present embodiment, after the turning members 20 and 30 are arranged along the frame structure, the waterproof layer 40 is laid on or inside the turning members 20 and 30, and the rising portions 22 and 32 are provided. The waterproof layer 40 may be attached to the notched seats 24, 34 in the lower region of the inner side surface of the. Therefore, the laying of the waterproof layer 40 becomes extremely easy and simple, the number of working steps can be reduced, and the upper end portion 40a of the waterproof layer 40 can be fixed to the turning members 20 and 30 made of foamed resin by a nail or the like. It is possible to securely fix 40, and it is possible to reliably prevent deterioration of the waterproof layer 40, water leakage, and the like.

Moreover, in this embodiment, the first and second recesses 25, 35, 36 for escaping the column member 3 and the horizontal members 4, 5 constituting the frame structure are provided in the rising portions 22, 32. Since it is formed on the side surface on the outdoor side, the provision of the rotating members 20 and 30 will not necessarily increase the thickness of the balcony wall. Further, because of this configuration, the turning members 20, 30 can be arranged such that the arrangement of the rising portions 22, 32 of the turning members 20, 30 on the indoor side is flat. Therefore, the arrangement of the cutout seats 24, 34 can be made flat, and as a result, the gap between the cutout seats 24, 34 and the waterproof layer 40 can be eliminated, and the cutout seats 24, 34 can be waterproofed. A waterproof structure in which the layer 40 is in close contact can be obtained.

Further, since diagonally inclined cant portions 23 and 33 are formed between the floor plate portions 21 and 31 and the rising portions 31 and 32, it is necessary to dispose a corner cant as in the conventional case. There is no need to reduce work man-hours. Needless to say, the present invention is not limited to the above embodiment. In particular, the matters described as not limited in the specification can be variously modified.

Furthermore, regarding the veranda structure to which the surrounding member of the veranda according to the present invention is applied, for example, the frame structure including the pillar member and the horizontal member, the floor member, and other members attached to the frame structure, The invention is not limited to the above, and various modifications are possible.
