Description of the Related Art A conventional structure for fixing a wall panel serving as a building frame is that a wall panel serving as a building frame is manufactured by a factory, and the wall panel is erected at a position to be an outer wall of the building frame in field construction. Was. Then, the eaves projecting outward from the wall panel and the outer wall projections such as the balcony floor are fixed, and thereafter, the siding material covering the surface of the wall panel and the external mounting member such as the aluminum sash frame are fixed. Was. A putty-like coking is provided between the external mounting member such as the siding material and the outer wall protrusion such as a balcony floor or an eave to prevent rainwater or the like from entering the building frame from a gap therebetween. A material or the like was filled in the gap between the two.

In recent years, building members have been prepared in advance at a factory for the purpose of improving productivity at a construction site, uniformity of quality, and improvement of quality. The study of a prefabrication method that can be completed is underway.

For this reason, rainwater or the like flowing downward along the wall panel (10) and the external mounting member (20) can be received by the upper surface of the pre-drainer (40), and furthermore, the received rainwater can be collected. In addition, from the lower end of the external mounting member (20) located on the side opposite to the building body, the external mounting member (20) can be guided downward on the side opposite to the building body. That is, since water flowing down from the lower end of the external mounting member (20) can be guided to the opposite side of the building frame by the pre-drainer (40), the gap between the lower end of the external mounting member (20) and the surrounding members can be guided. It is not necessary to close the gap generated at the step with a putty-like caulking material or the like. Since there is no need to use this caulking material, the waterproofing operation can be greatly simplified, and the productivity at the construction site can be improved.

Since the caulking material is not used for waterproofing the gap between the external mounting member (20) and the surrounding member, and the waterproofing is performed by the pre-drainer (40), the external mounting member (20) Further, the gap between the surrounding members can be set larger than the case where the gap between the surrounding members is filled with the caulking material. Thereby, the surrounding members (for example, the eaves 31)
There is no need to attach an external mounting member (20) such as siding after attaching the outer wall protrusion 30) such as a floor or a balcony floor 33, and the eaves (31) without the external mounting member (20) such as siding obstructing.

Next, the operation and effects of the above embodiment will be described. In the present embodiment, the upper end of the pre-drainer 40 is located between the lower part of the outer wall decorative member 21 as the external mounting member 20 and the wall panel 10, and the lower end continuous from the upper end of the pre-drainer 40 is the outer wall decorative member 21. Is located on the opposite side of the building frame. For this reason, rainwater or the like flowing down along the wall panel 10 and the outer wall decorative member 21 can be received by the upper surface of the pre-drainer 40, and the received rainwater can be collected by the outer wall decorative member 21. From the lower end located on the non-building body side, the outer wall decorative member 21 can be guided below the non-building body side. That is, the outer wall decorative member 21
Since the water flowing down from the lower end of the outer wall can be guided to the opposite side of the building by the pre-drainer 40, the gap formed between the lower end of the outer wall decorative member 21 and the surrounding members is closed with a putty-like caulking material or the like. No need. Since there is no need to use this caulking material, the waterproofing operation can be greatly simplified, and the productivity at the construction site can be improved.

Further, since the caulking material is not used for waterproofing the gap between the outer wall decorative member 20 and the outer wall protrusion 30 and the waterproofing is performed by a pre-drainer 40 or the like, the outer wall decorative member 20 and the outer wall protrusion 30 are protected. The gaps between the objects 30 can be set larger than in the case where the gaps between the objects 30 are filled with a caulking material. Accordingly, it is not necessary to attach the exterior wall decorative member 20 such as siding after attaching the exterior wall protrusions 30 such as the balcony floor 33 and the waterproof pan 34. That is, the outer wall protrusions 30 such as the balcony floor 33 and the waterproof pan 34 can be retrofitted without the outer wall decorative member 20 such as siding being in the way. For this reason, in factory production, the assembled wall panel 12 in which the outer wall decorative member 20 is fixed to the outer surface of the wall panel 10 in advance can be formed. Thereby, in the field construction, the wall panel 10 and the exterior wall decorative member
The assembled wall panel 12 integrally formed with the outer wall 20 can be simultaneously erected at the position where the outer wall is formed, and then the outer wall projection 30 can be fixed to the wall panel 10. That is, in the on-site construction, the wall panel 10 and the outer wall decorative member 20 can be handled as an integral body in the on-site construction, and the work of attaching the outer wall decorative member 20 to the wall panel 10 can be omitted. Thereby, the assembling work at the construction site can be facilitated, and the productivity at the construction site can be improved. In addition, the assembly wall panel 12 provides excellent quality in a component production and assembly plant because a skilled assembler can mass-produce a high-quality and stable product using a dedicated assembling machine. be able to.

In the present embodiment, the lower end of the pre-drainer 40 is positioned closer to the building frame than the ridge 35 at the end of the waterproof pan 34 of the outer wall projection 30 on the building frame 11 side. For this reason, rainwater or the like flowing down from the lower end of the
Can be guided and dropped to the side opposite to the building frame than the ridge 35 at the end of the building frame 11 side, and can be poured into the waterproof pan. The rainwater or the like that has fallen on the upper surface of the waterproof pan 34 does not propagate toward the building skeleton 11 because the waterproof pan 34 is inclined downward toward the outside. You can flow towards it. Thereby, waterproofness of the building frame 11 can be secured.

Further, in the present embodiment, the upper end of the retrofit drainer 50 is located closer to the building body 11 than the lower end of the retrofit drainer 40, and the lower end of the retrofit drainer 50 is located closer to the building frame than the lower end of the retrofit drainer 40.

The lower end of the drainer 50 is attached to the waterproof pan 34.
Water to the top of the waterproof pan
Can be reliably guided to the upper surface of the vehicle.

In this embodiment, a closing cover 60 for closing a gap between the pre-drainer 40 and the post-drainer 50 is provided. Therefore, even if the water flowing down from the lower end of the pre-drainer 40 is blown off in the horizontal direction by the strong wind, the blown water can be captured by the closing cover 60 without adhering to the building frame 11. Since the lower end of the closing cover 60 is fixed to the surface of the post-drainer 50 on the side opposite to the building frame, the closing cover 60
The water trapped by the water flows down from the lower end to the surface of the post-drainer 50 on the side opposite to the building frame, and can flow toward the outside of the building frame 11 through the post-drainer 50 and the outer wall protrusion 30. Thereby, even if it is blown off laterally from the lower end of the pre-drainer 40 by strong wind, from between the pre-drainer 40 and the post-drainer 50,
Water can be suppressed from entering the building skeleton 11, and the waterproofness of the building skeleton 11 can be secured.

Further, the gap between the pre-drainer 40 and the post-drainer 50 is closed by the closing cover 60 without being filled with a putty-like caulking material or the like. Waterproofing work can be performed without using, and assembling work can be facilitated. The folded part 44 is attached to the lower end of the
, And a locking portion 61 is formed at the upper end of the closing cover 60. For this reason, the locking portion 61 of the closing cover 60 is first drained.
The upper end of the closing cover 60 can be fixed to the lower end of the drainer 40 by simply inserting the upper end of the closing cover 60 into the folded portion 44 of the 40. Thus, the upper end of the closing cover 60 can be fixed to the lower end of the drainer 40 without using a fastening member such as a screw or a special fixing auxiliary member such as an adhesive, and the mounting work in the on-site construction can be performed. Can be easier.
