Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a waterproof pan for an eave-shaped part, and can be used for an entrance eave or a window eave of a building, or a flower box placed under a window.

[Background technology]

Traditionally, in eaves-like parts such as entrance eaves and window eaves of buildings,
Eaves gutters are sometimes omitted to improve the appearance. In such a thermal bridge type eave-like part, a waterproof pan or the like is provided on the upper surface side in order to collect and drain rainwater and the like. For waterproof pans, for example, mortar is applied with a trowel on site to form a sloped surface, or a flat board is supported tilted in both vertical and horizontal directions to form a bottom surface, and a drain pipe is connected to the lowest part. It is used.

[Problem to be solved by the invention]

By the way, in order to arrange the bottom plate at an angle in both vertical and horizontal directions,
For example, it is necessary to employ means such as using a tapered plate whose vertical dimension gradually increases or decreases along the longitudinal direction, or arranging a plurality of supporting members having different vertical dimensions at appropriate positions.

Among these, when a tapered plate material is used, there is a problem in that precision is required during manufacturing, such as the need to match the inclination of each side of the rectangular waterproof pan. On the other hand, when arranging a plurality of supporting members, there is a problem in that position adjustment during factory assembly or on-site installation becomes complicated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a waterproof pan for an eave-like part that can be easily manufactured and installed.

[Means to solve the problem]

The present invention is a waterproof pan used for an eave-shaped part extending from the outer wall of a building, and is provided with supporting members extending from each corner of a frame to approximately the center of the frame and tilted so that the center side is downward. The ends of the supporting members are connected by a connecting member placed approximately in the center of the frame, a bottom plate member is bridged between adjacent support members, and a waterproof sheet is laid over these bottom plate members to cover the entire surface of the frame. This constitutes a waterproof pan for the eaves-like part.

[For production]

In the present invention, each of the supporting members is inclined downward toward the approximate center of the frame, and each of the bottom plate members and the waterproof sheet laid over the bottom plate members are arranged in the central part or in a substantially funnel lower than the periphery. This results in a water gradient converging towards the central connecting member. For this reason, if you install a drain pipe etc. that connects the back side of the connecting member to the surface of the waterproof sheet,
Rainwater collected throughout can be drained away.

Here, the water gradient for collecting rainwater can be easily set by the slope of each support member, and the surface of each bottom plate member is ultimately covered with a waterproof sheet to ensure waterproofness, so there are no gaps between each other. For example, a plate material having the same planar shape as the frame body may be divided into sections following the support member. Therefore, the waterproof pan for eaves-shaped parts of the present invention does not require complicated adjustments, is easy to manufacture, and can be assembled easily, thereby achieving the above-mentioned object.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

As shown in FIG. 1, the building 1 of this embodiment is a prefabricated unit type house, which is constructed by assembling a box-shaped living room unit 2 and a roof unit 3.
An entrance eaves 5 is provided above which extends from the outer wall. The entrance eave 5 has a higher parapet 6 around the upper surface, and a waterproof pan 7 inside the parapet 6.

As shown in FIGS. 2 to 4, the waterproof pants include a rectangular frame IO.

The frame 10 is made by connecting bent steel plates arranged on four sides, and has an upper flange 12 and a lower flange 13 formed on the outer side of the upper edge and the inner side of the lower edge of the web 11 having a constant width. Among these, the upper flange 12 is fixed by covering the rosette 6 portion when attaching the waterproof pants to the entrance eaves 5. Note that after the upper flange 12 is fixed to the parapet 6, an appropriate exterior finishing material is covered. On the other hand, the lower flange 13 is formed continuously around the entire inner circumference, and each end is connected to each other by a corner member 14.

Further, a support member 15 and a connecting member 16 are arranged on the lower surface side of the frame 10.

The support members 15 are each made of a steel material having a C-shaped cross section and attached to the frame 10.
The base end is fixed to the lower surface of the lower flange 13 at the corner of the frame body 10, and the tip is extended to approximately the center of the frame body 10, and the base end is fixed to the lower surface of the lower flange 13 at the corner of the frame body 10. It is connected to each corner of a connecting member 16 made of a steel plate. Here, each support member 15 is inclined so that the distal end side is lower than the base end side, and the connecting member 16 is supported in a downwardly displaced state with respect to the lower flange 13.

As shown in FIG. 5, the bottom of the waterproof pants has a support member 15.
The bottom plate member 17 and the waterproof sheet 18 are sequentially laminated from above.

The bottom plate member 17 is made by dividing a rectangular plate material corresponding to the inner shape of the frame body 10 in a diagonal direction following the support member 15. is placed along the lower flange 13 with its edges placed along the lower flange 13, and is fixed with the central notch placed on the connecting member 16. Here, gaps are formed between the bottom plate members 17 that widen downward due to the inclination of the support members 15, but each gap is covered with a waterproof sheet 18 which is overlapped from above.

The basic portion 18A of the waterproof sheet 18 has a rectangular shape corresponding to the inner shape of the frame 10, and the portion 18A is attached to the frame 1.
0 and is fixed by pasting it from above the bottom plate member 17. On the other hand, the waterproof sheet 18 has expanded portions 18B on each of the four sides, and the portions 18B are raised along the web 11 from the bottom plate member 17 after the basic portion 18A is attached.
It is fixed so as to cover up to the upper flange 12.

Note that a hole 21 is formed in the center of the waterproof sheet 18, and a hole 22 is also formed in the center of the connecting member 16, and the holes 21 and 22 are aligned when pasting the waterproof sheet 18, and are The drain port 23 is inserted and fixed.

The lower end of this drain port 23 is connected to a drain pipe (not shown) arranged inside the entrance eaves 5, thereby allowing water to drain from the waterproof pants.

In this embodiment configured in this manner, the support member 15, the connecting member 16, and the bottom plate member 17 assembled on the frame IO give the general shape of the waterproof pants. That is, due to the inclination of the support member 15, each bottom plate member 17 is provided with an appropriate water gradient, and the bottom plate member 17 as a whole is formed into a shallow pyramidal shape with a lowered center. On the other hand, by covering the bottom plate member 17 and the frame lO with a waterproof sheet 18, constructing a central drainage port 23, waterproofing the surrounding area, etc., a drainage function as waterproof pants is provided. That is, the waterproof sheet 18 is originally flexible and deforms according to the general shape of the bottom plate member 17 and the like to become a concave vessel having a funnel-shaped bottom. Therefore, rainwater etc. received at the bottom flows from the periphery toward the center and is drained from the drain port 23.

According to this embodiment, the following effects can be obtained.

That is, the waterproof pants can collect rainwater received by the waterproof sheet 18 in the center and discharge it due to its funnel shape. Therefore, rainwater falling on the upper surface of the entrance eaves 5 can be collected and drained sequentially, and the pan can be used in the same way as a normal waterproof pan.

Further, the funnel-shaped water gradient at the bottom of the waterproof pants can be easily set or adjusted by adjusting the inclination of the support member 15. In particular, the support members 15 extend from each corner of the frame lO toward the center, and are fixed together by connecting the ends with the connecting members 16, so that assembly is easy. Further, the frame 10 may be a continuous long piece with simple four sides, and the complexity of the conventional system in which the bottom plate is sloped in two directions, vertically and horizontally, can be eliminated.

Furthermore, the approximate shape of the waterproof pants is determined by the frame body IO or the bottom plate member 17, and the final waterproofing is performed separately by the waterproof sheet 18, so it is easy to set the shape, and
Waterproofing treatment can be performed reliably. In particular, the bottom plate member 1
Since 7 is later covered with a waterproof sheet 1B, there is no problem even if there is a gap, and it can be easily created by dividing a rectangular plate material corresponding to the frame 10 along the pattern of the support member 15.

In this way, the basic assembly and waterproofing of the waterproof pants can be easily performed, making it possible to manufacture them quickly and efficiently, and to reduce manufacturing costs.

Note that the present invention is not limited to the above embodiments,
It also includes the following modifications.

That is, the support member 15 and the connection member 1 to the frame 10
6, the connecting member 16 may be connected after connecting the support member 15 at a predetermined inclination to the frame 1°, or the connecting member 16 may be maintained at a predetermined height with respect to the frame lO. These may be tied together using the support member 15.

Furthermore, the support member 15 is not limited to an independent rod-shaped member extending from the corner to the center of the frame 10, but if a reinforcing place or the like is originally arranged along a diagonal line on the frame 1o, the support member 15 is attached to the upper surface of this place. A spacer that becomes thinner toward the center may be placed to serve as a support member. Alternatively, a preset place itself may be used as a support member, and by providing a predetermined inclination, the bottom plate member 17 may be supported at an angle so that the center thereof is lowered.

Further, any method may be used to connect each part (welding or the like may be used when integrally constructed in a factory in advance, or bolt connection may be used when assembling on-site.

Furthermore, the material, shape, etc. of each member are arbitrary, and may be changed as appropriate in implementation. For example, the flanges 12, 13, etc. of the frame 10 may be omitted as appropriate;
The same applies to Furthermore, the support member 15 is not limited to C-shaped steel, and may be any suitable bar material or the like. Further, the connecting member 16 may have a rectangular shape with rounded corners or a circular shape, and the drain port 23 may also have another shape. In addition, the bottom plate member 17 is not limited to being manufactured by dividing a plate material corresponding to the frame 10 in the same manner as the support member 15, but can also be manufactured by separately forming triangular plates corresponding to the sections formed by the support member 15. You can stay there.

On the other hand, the overall shape of waterproof pants is not limited to a rectangle.
It is not limited to a trapezoid or a quadrangle, but may be a triangle, a pentagon, or more. Further, the installation position of the connecting member 16 is not limited to the center of the frame lO, but may be displaced to either side. In this case, the support member 15 may be arranged not along the diagonal line, but may be arranged so as to connect the corner of the frame lO and the connection member 16, and the bottom plate member 17 also has a shape corresponding to each section provided by the support member 15. And it is sufficient.

Furthermore, the waterproof pants of the present invention are not limited to the entrance eaves 5 as in the above-mentioned embodiments, but can also be applied to window eaves placed above windows, flower boxes placed under windows, etc. that protrude from the outer wall of a building and catch rainwater. It can also be widely used as a waterproof pan for other eaves.

〔Effect of the invention〕

As described above, according to the present invention, a funnel-shaped bottom can be formed by stretching a waterproof sheet over the bottom plate member etc. assembled on the frame, and the water gradient at the bottom can be adjusted to the slope of the support member.
