Embodiments of the present invention will be described below, but the present invention is not limited to these embodiments.
(First embodiment)
A first embodiment of the present invention will be described with reference to FIGS. 1 to 3 are perspective views showing the construction state in each process, and FIGS. 4 to 6 are cross-sectional views showing the construction state in each process.
  First, as shown in FIGS. 1 and 4, after the upper runner 2 and the lower runner 3 are fixed on the indoor side with a predetermined distance from the concrete underground wall 1, the runners are fixed by driving pins 5 (see FIG. 4). The studs 4 are erected at predetermined intervals.
  The upper runner 2 and the lower runner 3 of this example are channel members made of lightweight steel having legs opposite to each other on both sides, and the stud 4 is a lightweight steel (square pipe) having a predetermined length with a square cross section. is there. For this reason, after inserting the stud 4 horizontally or diagonally between the upper runner 2 and the lower runner 3, the stud 4 is raised and inserted between the legs of the upper runner 2 and the lower runner 3. Can be erected in a stable state. If necessary, the stud 4 may be screwed to the upper runner 2 and the lower runner 3.
  For the upper runner 2, the lower runner 3 and the stud 4, for example, a rust-proof material such as a galvanized iron plate, an aluminum / zinc alloy plated steel plate (galvalume steel plate), stainless steel (SUS) is preferably used.
  Next, as shown in FIGS. 2 and 5, a plate-like heat insulating material 6 is attached to the stud 4 with a screw (fixing member) 8 via a body edge material 7.
  The trunk edge member 7 of the present example is a channel member made of a lightweight section steel having legs opposite to each other on both sides. In addition, a plurality of guide grooves are formed in the plate-like heat insulating material 6 so that the leg portions of the trunk edge material 7 made of a channel member can be inserted. For this reason, by inserting the leg portion of the trunk material 7 into the guide groove provided in the plate-like heat insulating material 6, the inking of the trunk material 7 serving as a base set for the interior material or the like is automatically performed. The
  As the material of the plate-like heat insulating material 6, a material excellent in water resistance and heat insulating property is preferable, and for example, a synthetic resin foam having closed cells such as polystyrene foam, polyethylene foam, polyurethane foam and the like is suitable. In particular, extruded polystyrene (trade name “Styrofoam” manufactured by Dow Chemical Co., Ltd.) is most preferred because of its low water absorption.
  The plate-like heat insulating material 6 can have a thickness of about 25 mm to 150 mm, but in consideration of strength as a base, heat insulating properties, effective use of indoor space, etc., a thickness of about 35 mm to 100 mm is used. It is desirable to do.
  As the form of the plate-like heat insulating material 6, those whose actual processing is performed on the side surfaces can be suitably used. By setting it as such a form, while adjoining plate-shaped heat insulating materials can be couple | bonded without gap, level adjustment can be performed even if there is some unevenness. It should be noted that the actual processing can be performed on the three side surfaces or all the side surfaces according to the assignment of the plate-like heat insulating material 6.
  Further, a guide groove is also provided in the vicinity of the side surface of the plate-like heat insulating material 6, and as shown in FIG. 2, a trunk edge member 7a made of a channel member is attached across the two plate-like heat insulating materials 6 adjacent vertically. preferable. By setting it as such a form, the joint opening of a plate-shaped heat insulating material can be prevented.
  Generally, a steel material is used for the body rim material 7, but a hard plastic or the like can be used as long as it has a predetermined strength.
  As shown in the figure, it is preferable that the body frame member 7 is attached in a direction orthogonal to the stud 4, that is, in a horizontal direction. If it does in this way, confirmation of a screwing position will become easy and attachment of plate-like heat insulating material 6 can be performed easily.
  Next, if necessary, a moisture-proof film (not shown) made of a polyethylene film or the like is attached to the front surface of the plate-like heat insulating material 6, and then, as shown in FIG. 3 and FIG. (Or interior material) 9 is attached with screws 10.
  The interior base material (or interior material) 9 is not particularly limited. For example, calcium silicate board, flexible board, ALC board, gypsum board, wood, plywood, tile, precast concrete board, etc., which are usually used Can be used.
  In the drainage wall structure thus constructed, a space functioning as the drainage channel 11 is formed between the concrete underground wall 1 and the heat insulating wall. Then, the permeated water or dewed water that has permeated the concrete underground wall 1 flows down the drainage channel, is collected in a water collecting pit (not shown) through a drain pipe 12 at the bottom of the drainage channel, and is grounded by a pump or the like. Will be discharged.
  Moreover, since the drainage channel 11 is formed between the concrete underground wall 1 and the heat insulation wall using the plate-like heat insulating material 6, there are problems such as deformation of the drainage panel and peeling from the concrete underground wall as in the past. Therefore, a highly reliable drainage wall structure can be constructed. In addition, since the drainage wall structure can be constructed by a complete dry construction method, it is not necessary to fix the plate-like heat insulating material or interior base material with an adhesive having poor workability as in the past, and the workability is improved. In addition to being able to increase, separation and disassembly can be easily performed during disassembly.
(Second Embodiment)
A second embodiment of the present invention will be described with reference to FIG. FIG. 7 is a perspective view of a state where a stud is erected between the upper runner and the lower runner as viewed from the concrete underground wall side.
  Also in this example, the upper runner 2 and the lower runner 3 are channel members, but are different from the first embodiment in that a part of the leg located on the concrete underground wall side of the lower runner 3 is cut away. .
  As described above, the drain wall structure construction method of the present invention is a double wall construction method in which a drainage channel is formed between a concrete underground wall and a heat insulation wall, and the interval between the concrete underground wall and the heat insulation wall is increased. A highly reliable drainage wall structure can be constructed. However, if the interval between the concrete underground wall and the heat insulating wall is increased, a large dead space is generated and the effective utilization rate of the space is reduced.
  In this example, the interval between the concrete underground wall and the heat insulating wall is minimized, and a highly reliable drainage wall structure can be constructed. That is, as shown in FIG. 7, a predetermined notch 3b is provided in the leg 3a located on the concrete underground wall side of the lower runner 3, and this notch 3b can be used as a part of the drainage channel. is there. With this configuration, even if a large amount of water leaks, water does not stop in the lower runner portion made of the channel member, and the water can be reliably guided to the drainage channel. Water leakage can be effectively prevented.
  The width, depth, shape, etc. of the notch 3b provided in the lower runner 3 can be designed as appropriate. For example, in terms of depth, in order to minimize the amount of water retained in the lower runner portion, the channel member should be made as much as possible. It is preferable to form it deep enough to reach the base 3c.
  In addition, it is preferable to form at least one notch 3b between adjacent studs. Thereby, it can prevent reliably that water stops at a lower runner part.
  The plate-like heat insulating material and the interior base material (or interior material) can be attached in the same manner as in the first embodiment.
(Third embodiment)
A third embodiment of the present invention will be described with reference to FIG. FIG. 8 is a cross-sectional view showing a state in which a stud is erected between the upper runner and the lower runner.
  In this example, when the stud 4 is erected, a spacer 13 having a function of adjusting the distance between the stud 4 and the concrete underground wall 1 is attached.
  When a stud is used as a square pipe having high rigidity as in the first embodiment, it is possible to construct a heat insulating wall with high structural stability without providing a steadying member. On the other hand, when the basement floor height is high and the heat insulating wall is extremely high, or when a member with lower rigidity and lower cost than a square pipe, such as a channel member, is used as a stud, The spacer 13 is preferably attached between 4 and the concrete underground wall 1. As a result, the stud 4 can be steady and the structural stability can be enhanced, and even if the concrete underground wall 1 is uneven, the length of the plurality of spacers 13 can be reduced. By appropriately adjusting, the level of the stud 4 can be easily adjusted, and the occurrence of unevenness of the heat insulating wall can be prevented.
  The plate-like heat insulating material and the interior base material (or interior material) can be attached in the same manner as in the first embodiment.
