Description

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

[Background Art] Conventionally, eaves gutters may be omitted from eaves-like portions such as entrance eaves and window eaves of a building in order to improve the appearance. In such a gutterless eave-shaped portion, a waterproof pan or the like is provided on the upper surface side in order to collect and drain rainwater or the like that has fallen. Examples of the waterproof pan include a mortar that is troweled on site to form a slope, or a flat plate that is inclined and supported in two directions vertically and horizontally to form a bottom surface and a drain pipe is connected to the lowest part. Used.

[Problems to be solved by the invention]

By the way, in order to arrange the bottom plate obliquely in the vertical and horizontal directions, for example, a tapered plate material whose vertical dimension gradually increases and decreases along the longitudinal direction, or a plurality of support members having different vertical dimensions are appropriately positioned. It is necessary to adopt means such as disposition.

Among them, when a tapered plate material is used, there is a problem that precision is required at the time of manufacturing, for example, it is necessary to adjust the inclination of each side of a rectangular waterproof pan. On the other hand, when arranging a plurality of support members, there has been a problem that the position adjustment at the time of assembling a factory or installing on a site becomes complicated.

An object of the present invention is to provide a waterproof pan for an eave-shaped portion that can easily perform operations from manufacturing to installation.

[Means for solving the problem]

The present invention is a waterproof pan used for an eave-like portion protruding from an outer wall of a building, provided with a support member that extends from each corner of the frame to substantially the center of the frame and is inclined so that the center side is lowered, While connecting the front end of the support member with a connection member arranged substantially in the center of the frame, a bottom plate member is bridged between adjacent support members, and a waterproof sheet covering the entire frame body is laid from above these bottom plate members. This constitutes a waterproof pan for the eaves.

(Operation)

In the present invention, each support member is inclined downward toward the substantially center of the frame, and each of the bottom plate members and the waterproof sheet laid thereon are substantially funnels whose central portion is lower than the periphery. And a water gradient gathering towards the central connecting member is obtained. For this reason, if a drain pipe or the like communicating from the back side of the connecting member to the surface of the waterproof sheet is provided, it is possible to drain rainwater received as a whole.

Here, the water gradient for collecting rainwater can be easily set by the inclination of each support member, and each bottom plate member is finally covered with a waterproof sheet on the surface to ensure waterproofness, so that gaps and the like are mutually formed. For example, one obtained by dividing a single plate material having the same planar shape as the frame body according to the support member can be used. Therefore, the waterproof pan for the eaves-shaped part of the present invention does not require complicated adjustment and the like, and is easy to manufacture and can be assembled easily, thereby achieving the above object.

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the building 1 of this embodiment is a unit-type prefabricated house, which is constructed by assembling a box-shaped living room unit 2 and a roof unit 3 from an outer wall above a front door 4. An overhanging entrance eave 5 is provided.
The entrance eave 5 has a raised parapet 6 around the upper surface and a waterproof pan 7 inside the parapet 6.

As shown in FIG. 2 to FIG. 4, the waterproof pan 7 has a rectangular frame 10.

The frame body 10 is formed by connecting bent steel plates on four sides, and an upper flange 12 and a lower flange 13 are formed on the outside of the upper edge and the inside of the lower edge of a web 11 having a constant width. Of these, the upper flange 12 attaches the waterproof pan 7 to the entrance eave 5
When it is attached to the parapet 6, it is fixed over the parapet 6 part. After fixing the upper flange 12, the parapet 6 is covered with an appropriate exterior finishing material. On the other hand, the lower flange 13 is formed continuously on the entire inner circumference, and each end is connected to each other by a corner member 14.

A support member 15 and a connecting member are provided on the lower surface side of the frame body 10.
16 are arranged.

The support member 15 is formed by disposing a steel material having a C-shaped cross section along the diagonal direction of the frame body 10.
Are fixed to the lower surface of the lower flange 13 at the corners, and the front end is extended to substantially the center of the frame body 10 and connected to the respective corners of the connection member 16 made of steel plate disposed at the corresponding portion. Here, each support member 15 is inclined such that the distal end side is lower than the base end side, and the connecting member 16 is supported in a state of being displaced downward with respect to the lower flange 13.

As shown in FIG. 5, the bottom surface of the waterproof pan 7 is
The bottom plate member 17 and the waterproof sheet 18 are sequentially laminated from above.

The bottom plate member 17 is obtained by dividing a rectangular plate material corresponding to the inner shape of the frame body 10 in a diagonal direction according to the support member 15, and has a diagonal edge supported by the support member 15, and an outer base member. Is placed along the lower flange 13, and the central notch is fixed on the connecting member 16. Here, a support member is provided between each bottom plate member 17.
There is a gap that expands downward due to the inclination of 15,
Each gap is covered by a waterproof sheet 18 stacked from above.

The waterproof sheet 18 has a basic portion 18A having a rectangular shape corresponding to the inner shape of the frame 10, and the portion 18A is accommodated in the frame 10, and is attached and fixed from above the bottom plate member 17. On the other hand, the waterproof sheet 18 has expanded portions 18B on the four sides, respectively.
8B is raised from the bottom plate member 17 along the web 11 after attaching the basic portion 18A, and is fixed so as to cover up to the upper flange 12.

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.
2 is fitted when the waterproof sheet 18 is attached, and the drain port 23 is inserted and fixed from the front side. The lower end of the drain port 23 is connected to a drain pipe (not shown) arranged in the entrance eave 5, so that the waterproof pan 7 can be drained.

In the present embodiment configured as described above, the support member 15, the connecting member 16 and the bottom plate member 17 assembled on the frame 10 give the schematic shape of the waterproof pan 7. That is, an appropriate water gradient is given to each bottom plate member 17 by the inclination of the support member 15, and the whole bottom plate member 17 is formed in a shallow pyramid shape with the center lowered. On the other hand, the waterproof sheet 18 is provided on the bottom plate member 17 and the frame body 10, and the drainage function as the waterproof pan 7 is provided by performing the construction of the central drainage port 23 and the waterproof treatment of the surroundings. That is, the waterproof sheet 18 is originally flexible and is deformed according to the schematic shape of the bottom plate member 17 and the like to form a concave container having a funnel-shaped bottom. Therefore, rainwater or the like 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 pan 7 can collect and discharge the rainwater received by the waterproof sheet 18 at the center by its funnel shape. Therefore, it is possible to collect rainwater falling on the upper surface of the entrance eave 5 and to drain the rainwater one by one, so that it can be used similarly to a normal waterproof pan.

The funnel-shaped water gradient at the bottom of the waterproof pan 7 can be easily set or adjusted by the inclination of the support member 15. In particular, since the support member 15 extends from each corner of the frame body 10 toward the center and is connected integrally with the front end by the connection member 16, the support member 15 is integrally fixed. Also, frame
10 may be a continuous long object having simple four sides, and can eliminate the complexity of the conventional method in which the bottom plate is inclined in two directions in the vertical and horizontal directions.

Furthermore, since the waterproof pan 7 has a rough shape determined by the frame body 10 or the bottom plate member 17 and is finally waterproofed separately by the waterproof sheet 18, the shape can be easily set and the waterproofing process is surely performed. be able to. In particular, since the bottom plate member 17 is covered later with the waterproof sheet 18, there is no problem even if there is a gap or the like, and the bottom plate member 17 can be easily formed by dividing the rectangular plate material corresponding to the frame 10 along the support member 15.

As described above, the basic assembly or waterproofing of the waterproof pan 7 can be easily performed, and the production can be performed quickly and efficiently, and the production cost can be reduced.

The present invention is not limited to the above embodiment, but includes the following modifications.

That is, when attaching the supporting member 15 and the connecting member 16 to the frame 10, the connecting member 16 may be connected after connecting the supporting member 15 to the frame 10 at a predetermined inclination, or the connecting member 16 may be connected. May be maintained at a predetermined height with respect to the frame 10, and these may be connected by the support member 15.

Further, the support member 15 is not limited to an independent rod-shaped member extending from the corner of the frame 10 to the center, and when a reinforcing brace or the like is originally arranged on the frame 10 along a diagonal line, the supporting member 15 A spacer that becomes thinner toward the center may be placed as a support member. Alternatively, a preset brace itself may be used as a support member, and a configuration may be adopted in which the bottom plate member 17 can be inclined and supported so that the center is lowered by giving a predetermined inclination.

In addition, an arbitrary method may be used for each connection, and welding or the like may be performed in the case of integrally constructing in a factory in advance, or bolting may be performed in the case of on-site assembly.

Furthermore, the material, shape, etc. of each member are arbitrary, and may be appropriately changed in implementation. For example, the flanges 12 and 13 of the frame 10 may be omitted as appropriate, and the same applies to the corner members 14 and the like. Further, the support member 15 is not limited to the C-type steel material, but may use an appropriate bar or the like. Further, the connecting member 16 may be an octagon or a circle with a corner dropped, and the drain port 23 may have another shape. Further, the bottom plate member 17 is not limited to a plate material corresponding to the frame 10 and manufactured by dividing the plate material according to the support member 15, but a triangular plate material corresponding to a section formed by the support member 15 is separately formed. May be.

On the other hand, the overall shape of the waterproof pan 7 is not limited to a rectangle, and is not limited to a trapezoid or the like or a square, but may be a triangle or a pentagon or more. Further, the installation position of the connecting member 16 is not limited to the center of the frame body 10 and may be displaced to any side. In this case, the support member 15 may be disposed not at a position along the diagonal line but at a position connecting the corner of the frame 10 and the connection member 16, and the bottom plate member 17 may have a shape corresponding to each section provided by the support member 15. And it is sufficient.

Further, the waterproof pan 7 of the present invention is not limited to the entrance eaves 5 as in the above-described embodiment, but also receives rainwater overhanging from the outer wall of the building, such as a window eave disposed on a window or a flower box disposed under a window. It can be widely used as a waterproof pan for other eaves.

〔The invention's effect〕

As described above, according to the present invention, a funnel-shaped bottom can be formed by stretching a waterproof sheet from above a bottom plate member or the like assembled to a frame, and the water gradient of the bottom is reduced by the inclination of the support member.
