[Technical field of invention]

 The present invention relates to a roof parapet surrounding member for laying a waterproof layer on a roof parapet such as a steel frame building or a reinforced concrete building.

[0002]

[Technical background of the device]

 A waterproof layer (waterproof sheet) is laid on the roofs of steel-framed buildings and reinforced concrete buildings to prevent water from entering the building. On the other hand, an outer wall that surrounds this is often provided at the upper end of the roof, and this outer wall is generally called a parapet. The waterproof layer is also laid on the inner side of the parapet, but there are various problems in the laying as described below.

As an example of laying a waterproof sheet on this parapet, as shown in FIG. 6, the end portion 2a of the waterproof sheet 2 laid on the floor surface 1 is erected along the parapet 3 and the waterproof sheet is erected. A pad 4 is applied to the end portion 2a of 2 and a nail 5 or the like is struck on the parapet 3 via the pad 4. As a result, the end portion 2a of the waterproof sheet 2 is fixed to the parapet 3. A head tree 6 is laid on top of the parapet 3.

However, when ALC (lightweight aerated concrete) panel, cement extruded plate, etc. are used as the material for the parapet, the side wall itself is fragile, and if a large number of nails 5 are driven into the parapet 3, there is a risk of damage. Therefore, the end portion 2a of the waterproof sheet 2 may not be fixed. Even if the thickness of the parapet 3 is thin, it may be difficult to fix the end 2a of the waterproof sheet 2 with the nail 5.

When it is difficult to attach the end portion 2a of the waterproof sheet 2 to the parapet 3 by the example shown in FIG. 6, the example shown in FIG. 7 is generally used. Target.

That is, as shown in FIG. 7, the brick 7 or concrete or the like instead of the brick is used as a pressing member on the inner side of the end 2a of the waterproof sheet 2 standing upright along the side wall 3. Thus, the waterproof sheet 2 is pressed down.

However, when pressing with concrete, a curing period is required until it dries, and even when pressing with bricks 7 etc., since the end surface is pressed with mortar 8, this mortar 8 Must be cured until dry. Therefore, in each case, there is a problem that the construction period is prolonged. In addition, the use of mortar and the like is complicated and requires manual work by a skilled person. In addition, the parapet rising part is damaged due to the difference in movement between the wall and the parapet, which is a part of it, and the roof slab due to imitation (earthquakes, etc.).

Moreover, in addition to this, in the example as shown in FIG. 6, no adjustment is made for unevenness of the parapet 3 and the floor surface 1. Therefore, firstly, there is a problem that a force may be applied to the backing plate 5 and the backing plate 5 may come off, and secondly, the waterproof sheet 2 may be stretched by applying a force, In the worst case, the waterproof sheet 2 may be broken.

[0009]

[The purpose of the device]

 The present invention has been made in view of such circumstances, and even when the roof parapet is fragile or thin and the waterproof layer cannot be fixed, the waterproof layer can be easily, easily and in a short time. It has a function to insulate the movement of the parapet from the roof slab, and in addition to this, a roof parapet and a surrounding member of the roof parapet that fully considers the unevenness of the floor surface. It is intended to be provided.

[Specific explanation of the device]

 An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing a roof parapet according to an embodiment of the present invention in which a surrounding member is provided. FIG. 2 is an enlarged perspective view showing a single member around the roof parapet shown in FIG. 1. FIG. 3 is a cross-sectional view of the roof parapet shown in FIG. 1 in which the surrounding members are arranged.

As shown in FIG. 1, a floor surface 11 such as a concrete slab or an ALC plate is provided on the roof, and an outer wall, that is, a parapet 10 is provided so as to surround the edge of the roof. It stands from the floor 11. A heat insulating material 12 made of foamed synthetic resin or the like is laid on the general floor surface of the floor surface 11, and a waterproof layer 13 is laid on the heat insulating material 12. The waterproof layer 13 may be of various types, for example, asphalt waterproof, sheet waterproof, or the like.

Inside the parapet 10, a plurality of parapet turning members 20 according to the present embodiment are sequentially arranged in parallel. As shown in the enlarged view of FIG. 2, the swivel member 20 includes a floor plate portion 21 arranged along the floor surface 11 on the roof, a rising portion 22 that rises almost vertically from the floor plate portion 21, and A corner portion between the floor plate portion 21 and the rising portion 22 includes a cant portion 23 that is inclined (for example, at 45 °). It should be noted that the rising portion 22 may be inclined (obtuse or acute) in correspondence with the parapet 10 if the parapet 10 is somewhat inclined.

A large number of slits 24, 25 continuous from the floor plate portion 21 to the rising portion 22 are formed on the front and back surfaces of the floor plate portion 21 and the rising portion 22, respectively. As a result, the portions indicated by reference numerals 24a and 25a in FIG. 2 have a hinge structure. Therefore, the parapet surrounding member 20 can be provided with a flexible structure, and can follow the unevenness of the parapet 10 and the floor 1 as described later. The width of the slits 24, 25 is 0.5 to 5 mm, preferably 1 to 2 mm. Moreover, the depth of the slits 24, 25 is a majority of the plate thickness, and is preferably about ⅔ of the plate thickness. By doing so, elasticity is also expressed in the width direction, and it becomes flexible, and adjacent rotating members can be aligned with each other. However, the widths and depths of the slits 24 and 25 are not limited to these, and can be variously modified. In short, it is only necessary that the parapet surrounding member 20 be provided with a flexible structure that follows the unevenness.

The parapet turning member 20 is formed of the following materials. Polystyrene foam The use of this polystyrene foam has the advantages of being lightweight and low in cost, but on the other hand, it is not possible to use a non-solvent type adhesive (eg rubber type) and the curing time However, there is a problem that it takes a lot of time and the construction period becomes long, and there is also a problem that it is not possible to cope with the unevenness on the slab because it is a relatively hard material, and there is also a problem that it is deteriorated by ultraviolet rays.

Polyolefin Foam Polyolefin foam, for example, foam such as polyethylene and polypropylene, is light in weight and can use a non-solvent adhesive to shorten the construction time. . Furthermore, since it is softer than polystyrene, it can cope with unevenness on the slab, and there is no problem of deterioration due to ultraviolet rays. However, although it is slightly more expensive than polystyrene, 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 slabs because it is relatively soft, but the foaming ratio is relatively low, the cost is high, and the foam is heavy. However, it has the drawback of being hard.

In summary, the polyolefin foam of (2) is most preferable, the polystyrene foam of (2) and the rubber foam of (2) are preferable. However, the material of the parapet surrounding member is not limited to these materials and may of course be various materials. The expansion ratio in this case is preferably 10 to 80 times, more preferably 40 to 50 times.

Further, when molding the parapet surrounding member 20, various molding methods such as in-mold foam molding and extrusion foam molding are possible. Further, the slits 24 and 25 may be integrally formed at the time of molding, or may be formed by post-processing. Further, the entire surrounding member 20 may not be integrally molded, but may be composed of a plurality of parts that have been disassembled in various ways, and this may be assembled later as shown in FIGS.

Next, the operation of the parapet surrounding member will be described. As shown in FIGS. 1 and 3, a plurality of parapet rotating members 20 are arranged side by side along the parapet 10 and then the end portions of the waterproof layer 13 are laid along these rotating members 20. A pad plate 31 is put on the end of the waterproof layer 13, and the end of the waterproof layer 13 is fixed to the swivel member 20 and the parapet 10 by a nail 32 or the like. A head tree 33 is attached on the surrounding member 20 and the parapet 10.

As described above, even if the thickness of the parapet 10 is thin or the material itself is brittle, the nails 32 and the like can be inserted into the rising portions 22 of the parapet turning member 20, so that the thickness of the parapet 10 can be increased. The waterproof layer 13 can be fixed regardless of the material. In addition, since the mortar and concrete are not used for fixing the waterproof layer 13, the work period required for curing is unnecessary, the work period can be shortened, and the manual work of a skilled person becomes unnecessary. It can be done easily and easily.

Moreover, in addition to this, as shown in FIG. 2, a large number of slits 24 and 25 which are continuous from the floor plate portion 21 to the rising portion 22 are formed. The part indicated by has a hinge structure. Therefore, a flexible structure can be provided to the parapet member 20. Therefore, it is possible to flexibly follow the unevenness of the rooftop parapet 10 and the floor surface 11, and it is possible to easily adjust the unevenness. As a result, unnecessary force does not act on the pad plate 31 and the nail 32 of the waterproof layer 13, the pad plate 31 and the nail 32 do not come off, and unnecessary force also acts on the waterproof layer 13 itself. This does not occur, the waterproof layer 13 is not carelessly stretched, and there is no risk of the waterproof layer 13 breaking. It should be noted that these slits 24 and 25 can also function as grooves for discharging water vapor that may be stored under the waterproof layer 13.

Further, since the turning member 20 is formed so as to be obliquely inclined at the cant portion 23, the waterproof layer 13 can be disposed along the cant portion 23. Therefore, the waterproof layer 13 can be prevented from being sharply bent, and the deterioration of the waterproof layer 13 can be prevented.

Of course, 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. Further, although the slits 24 and 25 are formed on both front and back surfaces in the embodiment shown in FIGS. 1 and 2, the slits 24 and 25 are not limited to this. For example, as shown in FIG. 4, a slit 25 is formed only on the surface of the parapet surrounding member 20, and the portion indicated by reference numeral 25a has a hinge structure. Also by this, the turning member 20 can have a hinge structure, and can sufficiently follow the unevenness. Further, as shown in FIG. 5, the slit 24 is formed only on the back surface of the parapet turning member 20, and the portion indicated by reference numeral 24a has a hinge structure. This also makes it possible for the turning member 20 to have a hinge structure, and to sufficiently follow unevenness. As described above, the slits 24 and 25 may be formed on the surfaces, and the point is that the slits 24 and 25 need only be able to impart flexibility to the turning member 20.

[Effect of the device]

 As described above, according to the present invention, even if the thickness of the roof parapet is thin or the material itself is brittle, it is possible to insert a nail or the like into the rising portion of the parapet surrounding member, so The waterproof layer can be fixed regardless of the material. In addition, since the mortar and concrete are not used to fix the waterproof layer, the work period required for curing is not required, and the work period can be shortened, and the manual work of a skilled person is not required, which is easy and easy. It can be done easily.

Moreover, in addition to these, since a large number of slits are formed in the floor plate portion and the rising portion, it is possible to impart a flexible structure to the parapet surrounding member. Therefore, it is possible to flexibly follow the unevenness of the roof parapet and / or the floor surface, and it is possible to easily adjust the unevenness. As a result, unnecessary force is not applied to the attachment member of the waterproof layer, the attachment member does not come off, and unnecessary force is not applied to the waterproof layer itself, and the waterproof layer is broken. There is no fear.
