Description

INDUSTRIAL APPLICABILITY The present invention enables construction of a stable and strong eaves base, improves the designability and versatility of the eaves including the ends of verges, etc., enables quick and easy construction work, and finishes up to the decoration of eaves and the like. The present invention relates to an eaves foundation structure of a building capable of

The eaves of a building are formed so as to cover the building frame, base material, etc., and as the construction method and structure, as described in Patent Document 1, a member that covers the roof base material (called arabesque) ), and further like the eaves arabesque described in Patent Document 2, there are those in which separate members such as a curtain plate and a drain are assembled.
The arabesque described in Patent Document 1 is mainly composed of an engaging part that engages with the molded part of the horizontal roof shingle, a mounting part that is attached to the eaves of the building, and a drooping part that covers the eaves of the building. More specifically, the fixed part is configured in a flat shape or an L-shape that is screwed to the building frame or base material, or in a substantially U-shape that fits into the base material, etc., and the hanging part is formed in a stepped shape that follows the shape of the building frame. It is
On the other hand, in the arabesque described in Patent Document 2, there is proposed one in which the drainer and the curtain plate are fixed with fasteners such as screws. Furthermore, for the purpose of decoration, supporting materials are taken out from the walls to provide eaves or the like.

However, the karakusa described in Patent Literature 1 is poor in designability because the arabesque design conforms to the shape of the building body, and thus the exterior design is inevitably "stepped".
On the other hand, the arabesque described in Patent Literature 2 inevitably increases the number of parts, and there is a problem that construction takes time and effort. Furthermore, there is also the problem that the support materials and the like must be carried out from the walls, which must be carried out separately from the roof construction.
In addition, what can be said in common to Patent Documents 1 and 2 is that the improvement in designability and versatility at the edge of the eaves is still insufficient.

Therefore, the present invention can construct a stable and strong eaves base, improve the design and versatility of the eaves including the ends of verges, etc., and can perform construction work quickly and easily. To provide an eaves foundation structure of a building capable of finishing up to

DISCLOSURE OF THE INVENTION The present invention has been proposed in view of the above, and is a bottom end of an exterior material forming an exterior structure, or a bottom edge of an exterior material positioned on the lowest side among a plurality of exterior materials forming an exterior structure. The eaves foundation structure of a building which is further extended to the underwater side of , and is composed of a plurality of upper support members and lower support members each made of a rod-shaped member or a pipe member, and a connecting support member connecting both of these support members. Each of the upper support members is a member that supports the exterior structure and extends to the underwater side. The lower support member is arranged on the back side of the upper support member, and the upper end of the connection support member is orthogonally connected to the upper support member and the lower end of the connection support member is connected to the lower support member.

In addition, the eaves exterior material refers to the exterior material that is disposed further downstream than the exterior material that constitutes the exterior structure and is located on the most underwater side. It is easy to imagine horizontal roofing or tiles in which multiple exterior materials are arranged in the flow direction, but it may also be vertical roofing exterior materials that are continuous in the flow direction. It means that the eaves exterior material is arranged on the water side further than the lower end.

The present invention also proposes an eaves base structure for a building, wherein the lower supporting member is provided with an auxiliary member connected to the building frame in the eaves base structure.

The eaves foundation structure of a building according to the present invention includes a plurality of upper support members extending to the water side of various exterior structures, with eaves exterior materials along the upper surfaces thereof, and lower support members disposed on the back sides thereof. Since the support members made of three rod-shaped members or pipe members are integrally connected with the connecting support member connecting them by fastening members such as bolts, as shown in the illustrated embodiment described later, normal It is possible to easily construct a roof that gives a sharp impression with a sharp tip compared to a general roof. That is, in the illustrated embodiment, since U-shaped or hat-shaped rod-shaped members or pipe members are used as the respective support members, both the upper support member and the lower support member can be extended to the edge of the eaves. can be connected at an acute angle, and it is also possible to construct a sharp eaves structure. In addition, since at least one of the three support members is attached to the frame, the structure is easily and firmly integrated with the underwater side of the exterior structure. Moreover, since the upper support members adjacent to each other in the direction perpendicular to the flow direction are connected by the eaves exterior materials disposed across the upper support members adjacent to each other in the direction perpendicular to the flow direction, the upper support members and their Combined with the structure in which the lower support member on the back side and the connection support member that connects both support members are integrally connected, a stable eaves base structure covering the entire roof surface can be constructed integrally. The eaves exterior structure formed by the eaves exterior material fixed to the upper surface of the eaves foundation structure is easy to construct a roof that gives a sharp impression with a sharp tip compared to a normal general roof, and the eaves exterior structure. It is also possible to form a space that can be effectively used as a canopy to protect a given area from rain or sunlight. In addition, even if a positive load such as rainwater or wind blows from above, or a load such as wind blowing from below, a strong and strong eaves structure is maintained. It becomes the foundation structure that can be done.
As described above, the present invention is useful as a foundation structure for providing an eaves edge structure that is easy to install and is rich in design and excellent in design.

In addition, when the lower support member is provided with an auxiliary member connected to the frame, it can be easily attached to the frame, and a stronger and more stable eaves base structure can be constructed.

The eaves foundation structure of the building of the present invention extends further to the underwater side of the water ends of various exterior structures, and includes a plurality of upper support members and lower support members each made of a bar or pipe material, and both of them. The eaves foundation structure of a building comprising a connecting support member that connects support members, wherein each of the upper support members is a member that supports the exterior structure and extends to the underwater side. An edge-of-eaves covering material can be provided along the upper surface to straddle upper supporting members adjacent to each other in a direction perpendicular to the flow direction, the lower supporting member being arranged on the back surface side of the upper supporting member, and the connecting supporting member having an upper end thereof. The upper support member is connected perpendicularly to the upper support member and the lower end thereof is connected to the lower support member, and the upper support members adjacent in the direction perpendicular to the flow direction are connected by the eaves exterior material. , the upper support member may have at least an eaves exterior material along its upper surface, and the extending end of the upper support member and the eaves tip of the lower support member are connected by a fastening member, Both support members are integrally connected to the upper and lower ends of the connection support member by fastening members to construct the eaves base, and at least one of the upper support member, the lower support member, and the connection support member. One is attached to the frame.

The eaves foundation structure of the present invention includes three support members, (A) upper support member, (B) lower support member, and (C) connection , which are extended to the underwater side of various exterior structures as described above. Support members are integrally connected by fastening members such as bolts, and at least one of these three support members is attached to the skeleton.

The exterior structure in the present invention may be of any type such as vertical roofing, horizontal roofing, roofing tiles, etc., and the substrate to which it is attached and the members and structures for attaching to the substrate are not limited at all. Here, as described above, the eaves exterior material provided along the upper surface of the upper support member refers to an exterior material that is disposed on the further water side of the exterior material that constitutes the exterior structure and is located on the most underwater side. However, it is easy to imagine horizontal roofing or tiles, etc., in which multiple exterior materials are arranged in the flow direction, but it is also possible to imagine vertical roofing exterior materials that are continuous in the flow direction. In that case, the eaves exterior material is arranged further on the water side than the water end of the vertical roofing exterior material.
In addition, as a structure for attaching the exterior material to the base or the base, for example, a frame made of various materials such as a wooden frame, a steel frame, a concrete frame, etc. A support member such as a rafter or a base material such as a sheathing material may be used.

Among the exterior materials, the exterior materials located on the most underwater side (eaves side) constituting the exterior structure, and the eaves edge exterior materials that are arranged further on the water side are the exterior shapes of those exterior materials and the construction thereof. It may have a shape corresponding to the exterior shape of the exterior structure, or may have a shape completely different from those shapes, and the degree of freedom in shape selection is extremely large.
For example, a structure in which the exterior material is inclined at a constant gradient (angle) from the water side to the water side is common and widely known. The eaves portion formed by the eaves cladding material arranged on the lower side tends to give a sharp impression with a sharp tip compared to a general roof. Furthermore, it is also possible to form a space that can be effectively used as a canopy for sheltering from rain and sunlight in a predetermined area by such an eaves portion.
In addition, it may be formed to have a face plate portion with a different inclined surface or a curved face plate portion so as to be different from the inclination gradient of general exterior materials. It is also possible to make the roof give the impression that the eaves hang down deeply, thus enhancing the design.

It has already been explained that this eaves exterior material is provided along the upper surface of the upper support member (A), which will be described later in detail, and may be of any shape. It has an engaging part for doing. The configuration of the engaging portion is not particularly limited as long as it can be attached to the attachment support member .

The three support members, (A) upper support member, (B) lower support member, and (C) connecting support member, which constitute the eaves foundation structure of the present invention, will be described below. They are connected by fastening members with bolts.
In addition, each support member is a commonly used rod-shaped material or pipe material having a hat -shaped , square-shaped, tubular, Z-shaped, L-shaped, or U-shaped cross-section, and all of them have the same shape. No need to form. For example, by assembling a U-shaped (or hat-shaped) rod material and a square pipe material so that the square pipe material is enclosed inside the U-shaped rod material, the workability at the time of tightening is improved. It becomes easy, and high attachment strength can be obtained after fastening.

(A) Upper support member The upper support member in the present invention extends from the exterior structure to the underwater side, and the upper surface of the upper support member is provided along with the eaves exterior material. It may extend to the outside (that is, it also serves as a support member of the exterior structure), or it may be a newly provided one (that is, a new support member is connected to the support member of the exterior structure). In the latter mode, as in the illustrated embodiment described later, the upper support member, which is a rectangular pipe member, is assembled and fastened to the support member of the exterior structure, which is a rod-shaped member with a hat-shaped cross section . may be connected.

(B) Lower support member The lower support member in the present invention is arranged on the back side of the upper support member, and is a member that supports the eaves member (eaves ceiling member) as in the illustrated embodiment described later. It may be a member that also serves as The lower support member may be arranged substantially horizontally or inclined.
In addition, as described above, at least one of the support members is attached to the frame, not limited to this lower support member. good.

One end of the auxiliary member is connected to the lower support member directly or via another member, and the other end is attached to the frame (wall).
The auxiliary member may be straight or curved.
Also, the auxiliary members may be provided on all the lower support members, or may be provided at regular intervals (for example, every other member).
When such an auxiliary member is provided, the eaves member may be attached to the lower support member or may be attached to this auxiliary member.

(C) Communication support member The connection support member in the present invention connects (connects) the (A) upper support member and the (B) lower support member, and is arranged substantially vertically. It may be arranged in an inclined manner. This communication support member may be a single member, or may be a communication support member by combining a plurality of members whose lengths are adjustable. In addition, the connecting support member is not limited to connecting the ends of the (A) upper support member and the (B) lower support member, and connects either one or both lengthwise portions. It may be something to do. Therefore, a plurality of connecting support members may be provided, in which case the number of connection points increases and the integration strength is improved.

In addition, in the present invention, the eaves member mentioned in the above description will be briefly described below, although it is not an essential configuration.
The eaves member is a member that covers either or both of the back surface of the eaves exterior material and the back surface of the eaves. It refers to the decorative material on the most downstream side of the water. On the other hand, the eaves exterior material can be said to be a decorative material (also an exterior material) on the surface side which is the most under water. Moreover, it has the structure ( engagement receiving part) for attaching to the said attachment auxiliary|assistant material similarly to the said eaves edge exterior material.
In general, eaves members in a broad sense refer to all decorative materials that decorate the underside of the eaves. That is, the eaves member in the present invention may be composed of a single member or a plurality of members, and it is sufficient that the frontmost (outer) decorative member is integrally attached to the eaves exterior member. It is a thing.

Furthermore, the fastening member for connecting each support member in the present invention is generally a bolt or the like, but the specific configuration is not particularly limited. In general, when each support member constituting the eaves base structure is attached using this fastening member, since it is constructed on the water side of the exterior structure, there is no need to worry about rain. By locking or the like, it is possible to integrate with higher strength compared to attachment (integration).

In addition, it is desirable that at least a part of the eaves exterior material is attached to the exterior material located on the most downstream side or an exterior structure constructed by them. Preferably, it is at least partially attached to the back side of the structure.
In this way, it is desirable that at least a part of each of the eaves exterior materials and the eaves roof members is attached to the exterior structure constructed by the exterior materials other than the eaves exterior materials. It may be attached via a member, which itself need not be integral, and includes, for example, locking and polymerization. By directly attaching the eaves exterior material and the eaves member, both members can be connected to each other with high strength.

In addition, the eaves exterior material and the eaves member may be attached via an attachment auxiliary member interposed in a direction intersecting the flow direction and attached to the water bottom end of the upper support member. The auxiliary material may be in the shape of a plate that continues in the longitudinal direction, or may be partially interposed. When it is partially interposed, it may be provided in an extending form from the frame. In the embodiment using this mounting aid , it is preferable to use a continuous mounting aid in order to stably hold the eaves exterior material and the eaves member (including the design).
This mounting aid may be interposed in the overlapped portion between the engaging portion of the eaves exterior material and the engagement receiving portion of the eaves member. It may be fixed to a member.

The eaves exterior material and the eaves roof member may be spaced apart and a reinforcing member may be disposed in the space.
