Description

[Detailed description of the invention] (Industrial application field) The present invention includes a corner material and an elastic band-like body, and can easily and reliably protect the connecting part between the outer wall and the roof from rain. This invention relates to a drainage structure at the connection between an exterior wall and a roof, which is expected to improve the efficiency of exterior wall finishing work and make the exterior wall finish beautiful.

(Prior art) As shown in Figure 6, the conventional finishing treatment at the connecting part between the outer wall and the roof is to apply a draining piece b (a part of the wall base) at the upper edge of the roofing material a made of colored steel plate or the like. ), and apply a certain thickness of finishing mortar d to the wall base c to form the mortar wall e.
This was done by forming a wafer and applying a waterproofing treatment to its surface f.

(Problems to be solved by the invention) However, in this left-pipe construction method, the roofing material a and the finishing mortar d do not fit well, and the lower edge i of the mortar wall e absorbs water heavily during rainy days. And due to repeated drying in the blue sky, the edges of the two are torn and a gap g is created, and rainwater that has entered the gap g is absorbed by the lower surface of the mortar wall e (which is not waterproof because it is the surface caused by the edge torn). ) There was a risk that rainwater would seep into the inside of the mortar wall e from h and cross over the upper end of the draining piece b, and there was also a possibility that cracks would occur in the cut-off mortar wall e and rainwater would seep in through the cracked part. For this reason, the rain cover at the connection part j between the roofing material a and the finishing mortar d was likely to be defective. Furthermore, since the finishing mortar d was applied directly onto the roofing material a, there was no target for accurately determining the finishing thickness, resulting in poor work efficiency. Moreover, in addition to uneven finishing, gaps and cracks also occur as mentioned above, and the areas around these gaps and cracks may become discolored due to penetration of rainwater, making the appearance of the connection between the exterior wall and roofing material difficult. It was bad.

(Means for Solving the Problems) In order to solve the above problems, the present invention uses a corner material 1 and an elastic band-like body 2 made of soft resin.
It constitutes a drainage structure at a connection part 6 between a roof 5 of a shed, eaves, etc. and an outer wall 3, and the corner material 1 is attached to the outer wall finishing part in the longitudinal direction of the intermediate part of the mounting piece 12 attached to the wall base 11. It is characterized in that it is formed by protruding a horizontal piece 13 that forms the lower surface of 17, and that the elastic band-like body 2 is press-fitted into a groove 23 formed between the horizontal piece 13 and the roofing material 7. do.

(Function) Therefore, the elastic band 2 is in close contact with the roofing material 7, and the horizontal piece 13 waterproofs the lower surface of the outer wall finishing part 17, so that the rainwater that falls on the surface 18 of the outer wall finishing part 17 is absorbed by the outer wall finishing part 17. It is possible to make the water drop quickly at the tip 26 of the horizontal piece 13 without causing almost any infiltration into the interior, thereby ensuring that the connection part 6 between the outer wall 3 and the roof 5 is protected from rain. Further, the horizontal piece 13 forms a decorative joint 27 with good dimensional accuracy between the horizontal piece 13 and the roof material 7. Further, when finishing the outer wall with the finishing mortar 25, the tip 26 of the horizontal piece 13 functions as a left pipe setting tree.

(Example) Next, an example of the present invention will be described based on the drawings.

In the structure of the present invention shown in FIGS. 1 to 3, a corner material 1 and an elastic strip 2 are used to construct a drainage structure at a connecting portion 6 between an outer wall 3 and a roof 5. As shown in FIG. 2, the roof 5 is, for example, made of straw stick roofing, and a roofing material (in this embodiment, a roof edge material) 7 is provided at its upper end. The roofing material 7 is a bent body of colored steel plates, and includes an inclined flat part 10 spanning each of the straw bars.

The corner material 1 is formed as an extrusion molded body of synthetic resin, and is provided with a horizontal piece 13 that protrudes horizontally or diagonally downwardly in the longitudinal direction of the intermediate portion of the mounting piece 12 that is attached to the wall base 11. . A large number of through holes 15 are drilled at a predetermined pitch in the upper part 12a of the horizontal piece 13 of the mounting piece 12, and the lower end 16 of the mounting piece 12 is inserted into the wall base 11 with the lower end 16 substantially in contact with the roofing material 7. It is fixed by adhesive or double-sided adhesive tape. Said horizontal piece 1
The protrusion length of No. 3 is set equal to the finished thickness of the finished outer wall portion 17, and on its upper surface, a large number of fine grooves 19 extending in the longitudinal direction are formed over the entire width. The distal end portion of the horizontal piece 13 is a thick portion 21 that bulges downward.
The lower inner end surface of the thick part 21 is used as a locking part 22, and small diameter through holes 20 are bored at a predetermined pitch in the longitudinal center of the thick part 21. Note that the corner material 1 may be made of a light alloy.

The elastic band-shaped body 2 is made of soft synthetic resin or the like, and is formed into a band-like shape having a trapezoidal cross section. The elastic strip 2 is press-fitted into a groove 23 formed between the horizontal piece 13 and the roofing material 7, and therefore comes into close contact with the roofing material 7, and the connecting portion 6 between the outer wall 3 and the roof 5 is securely connected. It will be rained out. In addition, since the elastic band-shaped body 2 engages with the locking portion 22, falling off from the groove portion 23 is more reliably prevented. After the corner material 1 and the elastic strip 2 are combined in this way, finishing mortar 25 is applied to the wall base 11 in a thickness corresponding to the protruding length of the horizontal piece 13, and the surface is waterproofed. The outer wall finishing part 17 is formed by applying the finishing mortar 25 (the elastic band 2 may be press-fitted after applying the finishing mortar 25).
The tip 26 of the horizontal piece 13 serves as a plastering board, making the work of applying the finishing mortar 25 extremely easy. Furthermore, in this embodiment, the mounting piece 12 is provided with the through hole 15, and the horizontal piece 13 is provided with the grooves 19 and the through hole 20, so the finishing mortar 25 is provided with the through hole 15, the groove 19, and the through hole 20. It bites into the mortar retaining portion, which is the hole 20, and the edge breakage between the corner material 1 and the finished mortar 25 is more reliably prevented. Note that the through holes 20 also have the function of draining moisture from the applied finish mortar 25, thereby shortening the period until the finish mortar 25 dries. Further, the horizontal piece 13 serves as the lower surface of the outer wall finishing portion 17 and prevents the lower surface from being exposed to the lower surface of the outer wall finishing portion 17, and also prevents most of the rainwater that has fallen on the surface 18 of the outer wall finishing portion 17 from penetrating into the outer wall finishing portion 17. Instead, the liquid drops quickly at the tip 26 of the horizontal piece 5. As shown in the figure, when the horizontal piece 13 is provided so as to project obliquely downward, drainage becomes even better. Further, the horizontal piece 13 forms a decorative joint 27 with good dimensional accuracy between the horizontal piece 13 and the roof material 7, thereby improving the external appearance of the connecting portion 6 between the outer wall 3 and the roof 5.

4 and 5 show other embodiments of the present invention, and the corner material 1 shown in FIG.
The corner material 1 shown in FIG. A decorative protrusion 31 is provided that slightly protrudes upward over the entire length of the tip edge. The decorative protrusion 31
Decorates the lower end edge 33 of the wall plate 32 housed between the mounting piece 12 and the decorative protrusion 31.

In addition, in order to more reliably prevent the edges from breaking between the corner material 1 and the finishing mortar 25, on the horizontal piece 13,
A mortar retaining portion consisting of relatively high protrusions or ridges may be provided.

(Effects of the invention) As a result of the structure of the present invention configured as described above, the elastic band-like body is in close contact with the roofing material, and in addition, the horizontal piece falls on the surface 18 of the exterior wall finish part 17 in order to waterproof the lower surface of the exterior wall finish part. Since the rainwater can be made to drip at the tip 26 of the horizontal piece 5 without almost infiltrating into the finished part of the external wall, the connecting part between the external wall and the roof can be easily and surely protected from rain. In addition, since the elastic band is made of soft resin and has high elasticity, it adheres closely to the roofing material and is suitable for flat roofs, flat roofs, etc.
Or, even if there is a slight difference in the seam of the roofing materials, such as in the case of a slate roof, it will adhere closely to the roofing materials.

The horizontal piece forms the lower surface of the finished part of the exterior wall and forms a decorative joint with good dimensional accuracy with the roofing material, improving the appearance of the connection between the exterior wall and the roof.

Furthermore, when attaching the corner material to the wall base, the lower end of the attachment piece can function as a positioning part as described above, so that the work of attaching the corner material can be streamlined. In addition, when finishing the exterior wall with finishing mortar, the tip of the horizontal piece also functions as a left pipe setter, so it is possible to improve construction efficiency and achieve a beautiful finish.

Since the elastic band is separate from the corner material, it can be easily replaced when the elastic band becomes aged.
