Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an eaves bowl connection structure, and more particularly, to a technique for preventing a problem caused by a long accumulation of water leakage at an eaves connection location.
[0002]
[Prior art]
Conventionally, in the connection structure of the eaves ridge that includes an ear protruding outward at the upper end of the eave ridge and the joint including the rim is fitted to the outer surface between the ends of the eave ridge to be connected, There is also a problem that the water leaks from the butt edge of the water, and the water leaks from such a part accumulates for a long time, flows out with the dust and soils the front of the joint.
[0003]
[Problems to be solved by the invention]
The present invention has been made in view of such a problem, and prevents the problem caused by long accumulation of water leakage at the connection point of the eaves and prevents the outer surface of the joint from being soiled. It is an object to provide a connection structure.
[0004]
[Means for Solving the Problems]
In Claim 1, the ear | edge part 3 which protruded outward is provided in the upper end part of the eaves rods 1 and 2, and the joint 4 including the ear | edge part 3 is provided in the outer surface between the edge parts of the eaves rods 1 and 2 connected. The connecting structure of the eaves-fitting that fits outside, is characterized in that a drainage groove 5 is formed on the receiving surface 4a of the joint 4 that receives the lower surface portion 3a of the ear portion 3. According to such a configuration, water leakage from the butt edge of the ears 3, 3 can be drained from the drainage groove 5 formed in the receiving surface 4 a of the joint 4. It is possible to prevent the outer surface of the joint 4 from being soiled by being stored with the receiving surface 4a of the joint 4 for a long time and flowing out with dust.
[0005]
Further, a drainage hole 6 penetrating the outer surface of the bottom is formed in the middle of the drainage groove 5. According to such a configuration, the water leak in the drain groove 5 can be drained from the drain hole 6, the leak water can be hardly stored, and the outer surface of the joint 4 can be further prevented from being soiled. Can do.
[0006]
In claim 2 , the receiving surface 4a at the bottom of the joint 4 is inclined downward and the drainage groove 5 is formed at the lowermost part. According to such a configuration, the water leakage on the receiving surface 4a of the joint 4 can be caused to flow into the drainage groove 5, and the water leakage does not stay on the receiving surface 4a, and the outer surface of the joint 4 is further stained. Can be prevented.
[0007]
In Claim 3 , the protrusion 7 is formed in the lower surface part 3a of the ear | edge part 3, and the upper end part of the coupling 4 is latched to the upper end part of the ear | edge part 3, and the protrusion 3a is engaged in the drain groove 5 It is characterized by being. According to such a configuration, the joint 4 is locked to the upper end portion of the ear portion 3, and the protrusion 7 of the ear portion 3 is locked to the drainage groove 5. The connection strength of 4 can be increased.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
The basic configuration of the present invention will be described below. 1A is a broken perspective view, and FIG. 1B is an overall cross-sectional view.
[0009]
The eaves 1 is formed to have a substantially square cross section, and is provided with ears 3 protruding outward at the upper ends of the indoor and outdoor side walls 8 and 8. The joint 4 has an inner shape substantially equal to the outer shape of the eaves 1 and has a substantially constant thickness, for example, a resin molded product. Thus, the eaves 1 and 2 are connected by externally fitting the joint 4 including the ear 3 on the outer surface between the ends of the eaves 1 and 2 to be connected. A locking recess 9 is formed at the upper end portion of the ear 3 of the eaves 1, a hook portion 10 is formed at the joint 4, and the hook 4 is locked to the locking recess 9, thereby Are locked and connected to the eaves 1 and 2.
[0010]
In the joint 4, a drainage groove 5 is formed in the entire length of the receiving surface 4 a in the receiving surface 4 a of the joint 4 that receives the lower surface portion 3 a of the ear portion 3.
[0011]
According to such a configuration, water leaking from the butt edge of the ears 3, 3 can be drained from the drainage groove 5 formed in the receiving surface 4 a of the joint 4. It is stored for a long time between 3a and the receiving surface 4a of the coupling 4, and it flows out with dust and prevents the outer surface of the coupling 4 from being soiled.
[0012]
FIG. 2 shows an embodiment of the present invention, in which a drainage hole 6 penetrating the outer surface of the bottom portion is formed in the middle of the drainage groove 5.
[0013]
In the present embodiment, it is possible to drain the leakage water in the drainage groove 5 from the drainage hole 6, almost eliminate the storage of the leakage water, and further prevent the outer surface of the joint 4 from becoming dirty. it can.
[0014]
Further, in the present embodiment, the receiving surface 4a at the bottom of the joint 4 is inclined downward and the drainage groove 5 is formed at the lowermost part, and water leakage on the receiving surface 4a of the joint 4 is transferred to the drainage groove 5. Thus, the water leakage does not stay on the receiving surface 4a, and the outer surface of the joint 4 can be further prevented from being soiled.
[0015]
FIG. 3 shows still another embodiment. In this embodiment, a ridge 7 is formed on the lower surface 3 a of the ear 3, and the upper end of the joint 4 is locked to the upper end of the ear 3. At the same time, the protrusion 3 a is inserted into the drainage groove 5. Even in such a state of engagement, a shallow drainage groove 5 is formed.
[0016]
In the present embodiment, the joint 4 is locked to the upper end portion of the ear portion 3, and the protrusion 7 of the ear portion 3 is locked to the drainage groove 5, so that the joint 4 can be locked at two points in the vertical direction. It is possible to increase the connection strength.
[0017]
【The invention's effect】
In Claim 1, it has the ear | edge part which protruded outward in the upper end part of the eaves bowl, and is the connection structure of the eaves hook which externally fits a joint also including an ear | edge part on the outer surface between the edge parts of the connected eaves bowl. Since the drainage groove is formed on the receiving surface of the joint that receives the lower surface portion of the ear part, water leakage from the butt edge of the ear part can be drained from the drainage groove formed on the receiving surface of the joint, There is an advantage that it is possible to prevent water leakage from being stored for a long time between the lower surface portion of the ear portion and the receiving surface of the joint, and flowing out together with the dust to contaminate the outer surface of the joint.
[0018]
Since further is formed with a drain hole penetrating the outer bottom surface in the middle of the drains, the water leakage wastewater groove can be drained from the drain hole, it can be eliminated almost for storing water leakage, even There is an advantage that the outer surface of the joint can be prevented from being soiled.
[0019]
In claim 2 , since the receiving surface of the bottom of the joint is inclined downward and the drainage groove is formed at the lowermost part, in addition to the effect of claim 1, water leakage on the receiving surface of the joint is drained. There is an advantage that it is possible to flow into the groove, no leakage of water is retained on the receiving surface, and further prevent the outer surface of the joint from being soiled.
[0020]
In Claim 3 , since the protrusion is formed in the lower surface part of the ear part, the upper end part of the joint is locked to the upper end part of the ear part, and the protrusion is engaged with the drainage groove. In addition to the effect, the joint is locked to the upper end of the ear, and the protrusion of the ear is locked to the drainage groove, so that it can be locked at two points on the upper and lower sides and the connection strength of the joint can be increased. There is an advantage.
