BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rooftop parapet surrounding member for laying a waterproof layer on a rooftop parapet such as a steel frame building or a reinforced concrete building.

[0002]

[Technical background of the invention] A waterproof layer (waterproof sheet) is laid on the roof of a steel-framed building, a reinforced concrete building, or the like, thereby preventing infiltration of moisture into the building. On the other hand, the roof top is often provided with an outer wall surrounding the periphery, 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 laying as described below.

As an example of laying a waterproof sheet on this parapet, as shown in FIG. 4, an end 2a of a waterproof sheet 2 laid on a floor 1 is erected along the parapet 3,
A patch 4 is applied to the end 2 a of the waterproof sheet 2, and a nail 5 or the like is hit on the parapet 3 via the patch 4. Thus, the end 2 a of the waterproof sheet 2 is fixed to the parapet 3. In addition, on the upper part of the parapet 3, a cap 6 is laid.

However, as a parapet material, A
When an LC (lightweight cellular concrete) panel, a cement extruded plate, or the like is used, 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 breakage. Sometimes it cannot be fixed. Also, even when the thickness of the parapet 3 is thin, it may be difficult to fix the end 2 a of the waterproof sheet 2 with the nail 5.

When it is difficult to attach the end 2a of the waterproof sheet 2 to the parapet 3 according to the example shown in FIG. 3, an example shown in FIG. 5 is generally used. is there.

That is, as shown in FIG. 5, brick 7 or concrete or the like instead of brick is applied as a pressing member to the inner side of the end 2a of the waterproof sheet 2 erected along the side wall 3. Presses the waterproof sheet 2.

[0007] However, when pressed with concrete, a curing period until drying is required, and
Even when the mortar 8 is pressed by the brick 7 or the like, the end face is pressed by the mortar 8, so that the mortar 8 must be cured until it dries, and therefore, a construction period is required. Therefore, in any 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, since the rise of the parapet is damaged due to the difference in movement between the wall and the parapet that is a part thereof and the roof slab due to imitation (earthquake, etc.), it is necessary to insulate the motion of the parapet and the slab.

In addition, in addition to this, in the example shown in FIGS. 4 and 5, when the waterproof sheet 2 is installed on the roof,
Water vapor may accumulate below the tarpaulin and cannot be discharged to the outside of the building. As a result, if a heat insulating layer is provided below the tarpaulin, There is a problem of deterioration.

[0009]

[Purpose of the Invention] The present invention has been made in view of such circumstances. Even if a rooftop parapet is fragile or its wall thickness is small and a waterproof layer cannot be fixed, it is easy, simple and short-term. A waterproof layer can be attached between them, and it has the function of insulating the movement of the parapet and the roof slab. In addition, it provides a roof parapet circulating member that can discharge water vapor under the waterproof layer. It is intended to be.

[0010]

SUMMARY OF THE INVENTION In order to achieve this object, a roof parapet wrapping member according to the present invention is provided inside a rooftop parapet and is a rooftop parapet wrapping member for laying a waterproof layer. A synthetic resin foam having an L-shaped cross section, comprising: a floor plate portion provided below the waterproof layer along the nearby floor surface; and a rising portion provided inside the waterproof layer along the rooftop parapet. , And a plurality of continuous grooves for discharging water vapor below the waterproof layer are formed in the floor plate portion and the rising portion.

According to the present invention having the above-described configuration, even when the rooftop parapet is thin or the material itself is brittle, a nail or the like can be inserted into the rising portion of the parapet surrounding member. The waterproof layer can be fixed irrespective of the thickness, the material, and the like. In addition, when fixing the waterproof layer, mortar, concrete, etc. are not used, so the construction period required for curing is not required, and the construction period can be shortened. Can be performed. The movement by imitation between the parapet and the roof slab can be insulated.

Further, in addition to the above, since grooves for discharging water vapor on the lower surface of the waterproof layer are formed in the floor plate portion and the rising portion, it is possible to discharge water vapor present below the waterproof layer to the outside. It is possible to prevent deterioration of the heat insulating material provided below the waterproof layer and prevent the waterproof layer from bulging.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One 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 state in which a rotatable member of a rooftop parapet according to an embodiment of the present invention is provided. FIG. 2 is an enlarged perspective view showing a single turning member of the rooftop parapet shown in FIG. FIG. 3 is a cross-sectional view of the rooftop parapet shown in FIG. 1 in which a surrounding member is provided.

As shown in FIG. 1, a roof 11 is provided with a floor surface 11 such as a concrete slab or an ALC plate, and an outer wall, that is, a parapet 10 is surrounded by a floor so as to surround the edge of the roof. It stands from the surface 11. The floor 1
Insulation material 1 made of foam synthetic resin etc.
2 is laid, and a waterproof layer 13 is
Is laid. The waterproof layer 13 may be of various types, for example, asphalt waterproof, sheet waterproof and the like.

Inside the parapet 10, a plurality of loop members 20 of the parapet according to the present embodiment are sequentially arranged in parallel. The turning member 20 is, as shown in FIG.
A floor plate portion 21 arranged along the rooftop floor surface 11 and a rising portion 22 that rises almost vertically from the floor plate portion 21.
And a canting portion 23 which is inclined obliquely (eg, at 45 °) at the corner between the floor plate portion 21 and the rising portion 22.

The rising portion 22 may be correspondingly inclined (at an obtuse angle or at an acute angle) if the parapet 10 is slightly inclined. A plurality of grooves 2 communicating with each other on the back side are provided on the back side of the floor plate portion 21 and the rising portion 22.
4, 24... Are formed. A plurality of grooves 25, 25 communicating with each other are also provided on the surface side of the floor plate portion 21 and the rising portion 22.
...... is formed. These grooves 24 and 25 serve to discharge the water vapor below the waterproof layer 13 as described later.

The turning member 20 of such a parapet is
It is formed from the following materials. Polystyrene foam When this polystyrene foam is used, it is advantageous in that it is lightweight and inexpensive, but on the other hand, a non-solvent-based (for example, rubber-based) adhesive cannot be used, and the curing time is reduced. However, there is a drawback that the construction period is lengthened, and there is also a problem that it is difficult to cope with unevenness on the slab due to a relatively hard material, and furthermore, there is a problem that it is deteriorated by ultraviolet rays.

Polyolefin Foam In the case of a polyolefin foam, for example, a foam such as polyethylene or polypropylene, it is lightweight and
A non-solvent-based adhesive can be used, and the construction time can be shortened. Furthermore, since it is softer than polystyrene, it can respond to irregularities on the slab,
Moreover, there is no problem of deterioration by ultraviolet rays. However, the cost is slightly higher than that of polystyrene, but it is expensive, but it is not so expensive, and there is no problem in terms of cost.

Rubber Foam Rubber foam is relatively soft and has the advantage of being able to cope with irregularities in the slab, but has a relatively low foaming rate, and is expensive and heavy. And has the disadvantage of being hard.

In view of the above, a polyolefin foam is most preferred, and then a polystyrene foam and a rubber foam are preferred. However, the material of the surrounding member of this parapet is not limited to these.
Of course, various things may be used. In this case, the expansion ratio is preferably from 10 to 80 times, and more preferably from 40 to 50 times.

Further, when the surrounding member 20 of the parapet is molded, a molding method in which the parapet is integrally formed by in-mold foam molding is possible. Further, instead of integrally forming the circling member 20, the circling member 20 may be constituted by a plurality of variously disassembled parts, which may be assembled later as shown in FIGS.

Next, the operation of the surrounding member of the parapet will be described. As shown in FIGS. 1 and 3, after the plurality of parapet wrapping members 20 are arranged in parallel along the parapet 10, the end of the waterproof layer 13 is laid along these wrapping members 20. An end of the waterproof layer 13 is applied to the end of the waterproof layer 13 by a nail 32 or the like, and the end of the waterproof layer 13 is fixed to the turning member 20 and the parapet 10.
It is to be noted that a casket 33 is mounted on the surrounding member 20 and the parapet 10.

As described above, even when the thickness of the parapet 10 is thin or the material itself is brittle, the nail 32 or the like can be inserted into the rising portion 22 of the surrounding member 20 of the parapet, so that the thickness of the parapet 10 can be reduced. Regardless of the material, the waterproof layer 13 can be fixed. In addition, since the mortar, concrete, and the like are not used for fixing the waterproof layer 13, the construction period required for curing is not required, and the construction period can be shortened. It can be done easily.

Moreover, in addition to these, as shown in FIGS. 1 and 3, grooves 2 for discharging water vapor below the waterproof layer 13 are formed.
4 and 25 are formed in the floor plate portion 21 and the rising portion 22, and the waterproof layer 13 is formed through these grooves 24 and 25.
Water vapor existing on the lower side can be discharged to the outside, and deterioration of the heat insulating material 12 disposed below the waterproof layer 13 can be prevented. As described above, the grooves 24 and 25 only need to be able to discharge the water vapor below the waterproof layer 13,
The number may be various. Further, grooves 24,
25 is formed on both the back side and the front side of the circling member 20, but may be formed only on the back side, or may be formed only on the front side. It may be formed so as to penetrate through the inside of 20.
In short, it is only necessary that the water vapor under the waterproof layer 13 can be discharged.

Further, since the circling member 20 is formed to be obliquely inclined at the can portion 23, the waterproof layer 13 can be disposed along the can portion 23. Therefore, it is possible to prevent the waterproof layer 13 from being sharply bent, and to prevent the waterproof layer 13 from deteriorating.

The present invention is, of course, not limited to the embodiment described above. In particular, matters described as not being limited in the specification can be variously modified.

[0027]

As described above, according to the present invention, even if the rooftop 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 surrounding member of the parapet. Therefore, the waterproof layer can be fixed regardless of the thickness and the material. Also, when fixing the waterproof layer, mortar, concrete, etc. are not used, so the construction period required for curing is not required, and the construction period can be shortened. Can be performed.

Further, in addition to these, grooves for discharging the water vapor on the lower surface of the waterproof layer are formed in the floor plate portion and the rising portion, so that the water vapor present below the waterproof layer can be discharged to the outside. It is possible to prevent deterioration of the heat insulating material disposed below the waterproof layer. Further, by providing the groove, it is easy to cope with uneven ground.
