Description

The present invention relates to a method for constructing a building wall structure for cooling and heating that radiates cooling and heating while forming a wall body that defines a space in the building, and in particular, after ensuring a low-cost and comfortable cooling and heating living environment. Thus, the present invention relates to a construction method of a building wall structure for cooling and heating that can be widely applied to renewal, post-construction, small buildings, and the like.

  Conventionally, the example of the radiation panel attached to a building wall for radiation cooling / heating is known like patent document 1. FIG. This is because the heat radiation part is attached to the wall of the plaster board via a lath, and this heat radiation part is formed by embedding a reinforcing material together with the hot water pipe in the molding hardened material, and thereby, the periodicity due to the temperature cycle. The panel is prevented from cracking even if it receives a change in thermal stress. However, since the heat radiation part requires a structure for heat radiation in addition to the structure of the wall body, the wall body receives a large load from the heat radiation part together with the cost problem due to the complexity of the structure, It was substantially difficult to make the entire surface of the wall a heat radiation part. In order to solve this problem, the present inventor previously proposed a partition panel described in Patent Document 2. This partition panel is factory-produced as a PC panel that constitutes a building wall structure for cooling and heating capable of full-surface heat radiation, and enables cost reduction with a simple configuration while ensuring its dimensional accuracy and self-supporting strength. It is possible to enjoy a comfortable living environment by radiant cooling and heating over the entire wall panel at low cost.

However, although the building wall structure using the partition panel can provide a comfortable living environment at a low cost, it is necessary to install special handling means such as heavy machinery for handling a large weight at the construction site during the construction. Therefore, the problem is that the application is limited to the construction of large-scale new buildings.
JP-A-11-324185 JP 2003-160985 A

The building wall panel 11 for air conditioning shown in FIG. 3 is configured by two perforated plate materials 12 and 12 in the same manner as described above. The perforated plate materials 12 and 12 are formed with one or more through-holes 5a through which the heat medium in the flow path 3 can be discharged into the room R through the plate material. The through-holes 5a are a large number of pores arranged at equal distances on the entire surface of the wall body 11 as shown in the figure, and the through-holes 5b having large openings and the discharge ports 5 of the wall body 11 are combined or selected as necessary. As a result, it is possible to achieve rapid air-conditioning and various indoor ventilation controls by the direct action of the heat medium.

  As shown in the cross-sectional view of FIG. 4A, the specific structure of the wall body 11 is such that a heat conductive plate is fixed to the perforated plate members 12 and 12 as backing materials 13 and 13 from the flow path 3 to the room. A through hole 5a reaching R is formed. Insertion grooves 14 and 15 are formed in the upper end and the lower end of the wall body 11, and fixing means are formed by attaching a hanging member 16 and a baseboard 17 having a corresponding structure to the building frame B, respectively. A partition is formed by inserting 11 and fixing it to the building frame B. The perforated plate materials 12 and 12 can easily ensure the self-supporting strength as a partition by the backing materials 13 and 13.

  In addition, with respect to the single configuration by the single flow path 3, this is divided into front and rear portions for each heat radiation part, and an example of a double configuration is shown in the center of the wall body 11 as shown in the cross-sectional view of FIG. By providing the partitioning portion 18 made of a heat insulating material and dividing the flow path 3 into two, it becomes possible to control the cooling and heating of the rooms R1 and R2 on both sides separately.

(Configuration example 3)
The building wall panel 21 for cooling and heating shown in the perspective front view of FIG. 5 is a casing 22 formed so as to be self-supporting by a mesh material as shown in the enlarged sectional views (a) and (b) of the single configuration and the double configuration of FIG. And perforated materials 23 and 23 mounted on both surfaces thereof. The casing 22 is formed by expanding metal or the like into a wall shape having a predetermined thickness, and the upper and lower portions thereof are fixed to the building casing B via fixing means 24 and 25 such as bolts. The perforated materials 23 and 23 on the surface are selected from various interior materials including a material mainly having air permeability such as a cloth material and a non-woven fabric, and are attached to the housing 22.

  The building wall structure with the building wall panel 21 for cooling and heating having the above-described configuration can secure a self-supporting strength and apply a wide range of finishing materials having air permeability by making the hollow wall body a cage structure made of a mesh material. When the through-holes are evenly arranged in the hollow wall body, a uniform living air can be formed by the uniform discharge air, and a comfortable living environment can be formed. Since this horizontal layer circulation air can occupy ventilation for each streamline, a healthy and comfortable living environment can be formed at low cost including medical use that requires individual clean ventilation within the occupied space.

(Configuration example 4)
The building wall panel 31 for cooling and heating shown in the perspective front view of FIG. 7 is an enlarged sectional view of the two plate members 32 and 32 opposed to each other with a gap therebetween, as shown in FIG. It is a molded body composed of a pipe line 33 arranged in a gap between them, and a filler 34 made of concrete or the like that fills the surrounding space within the gap range, and is constructed with a spacer 35, a holding material 36, etc. It is configured to be capable of filling and molding on site.

The two plate members 32 and 32 are heat radiating plates that radiate cold / hot heat received from the filler 34 outward.
A panel opening 37 for filling the filling material 34 into the internal space is formed in the upper part. The pipe line 33 is a pipe material made of a thermally conductive cross-linked polyethylene material or the like that transmits cold / hot heat of the heat medium to the filler 34, and is provided with a supply port 33a and a discharge port 33b for forcibly flowing the heat medium at both ends. . The supply port 33a and the discharge port 33b are connected to the supply / discharge tube 38 at the panel openings 37 of the two plate members 32, 32. The filler 34 is a filler such as concrete having a self-supporting strength as a partition wall, and uses a heat conductive material that transmits cold / hot heat between the pipe line 33 and the plate member 32.

  The spacer 35 is held at a predetermined distance by attaching both ends thereof to the inner surfaces of the two plates 32 and 32. At both ends of the spacer 35, fitting portions 35a and 35a for detachably fitting between the two plate members 32 and 32 are provided. The holding member 36 is formed by a mesh-like member such as a welded mesh, and is fixed to the spacer 35 and is then positioned and held by attaching a pipe line 33 made of a pipe member.

  The building wall panel 31 for cooling and heating having the above-described structure is installed as a partition wall in an unfilled state after the hanging member 16 and the baseboard 17 are attached to the building frame B, and filled with solid concrete and the like from the panel opening 37 to be solidified. By filling a material or a filler made of a flowable material that can be extracted later, a thermal radiation partition wall can be easily formed without requiring a special heavy machine. Moreover, workability is securable by the fitting parts 35a and 35a. This partition wall by the building wall panel 31 for cooling and heating connects the pipe 33 to the supply / exhaust pipe 38 in the panel opening 37 and forcibly allows the cooling / heating medium to flow through, so that two plates 32, Cold and hot heat is radiated from 32 to the room. In this case, a stable temperature environment as a heat storage material can be obtained by increasing the heat capacity of the filler 34.

  In addition, as shown in FIG. 8C, the building wall panel 31 for cooling and heating is provided with a partition portion 39 that divides the interior into front and rear portions for each heat radiating portion, and is formed of a heat insulating material, thereby individually It becomes possible to control the air conditioning. Furthermore, as shown in FIG. 9, a large heat radiation area can be secured by using a plate 32a having an uneven surface on the panel surface, so that efficient air conditioning can be achieved.

(Configuration example 5)
The building wall panel 41 for cooling and heating constituting the building wall structure shown in the cross-sectional view of FIG. 10 has a pipe 33 made of a pipe material for forcedly flowing through the heat medium as shown in FIG. The external wall of the building is constructed in advance by factory production as an external heat insulation type external wall panel in which the heat insulating material 43 and the external material 44 are attached on one side to the PC plate 42 formed by precast concrete molding, and this is attached to the outer periphery of the building frame B. Configure.

  More specifically, the building wall panel 41 for cooling and heating is provided with structural rebars 45 for securing the outer wall strength in the vertical direction, and projecting at the ends as connecting portions 45a ... Mold. On the building frame B side, an insertion bar 46 for attaching the cooling / heating building wall panel 41 is projected, and when the outer wall is constructed, the building wall panel 41 for cooling / heating is transported to the closest position of the construction site. The building wall panel 41 for cooling and heating is fitted into the outer periphery of the building frame B by a lift operation or the like from the outside of the building. The connecting portions 45a on the outer periphery of the building wall panel 41 for cooling and heating are connected to the insertion bars 46 of the building frame B by welding, and the gap is filled with a heat conductive filler 47 such as mortar. The heat insulating material 43a and the exterior material 44a are attached to the outer peripheral surface of the building frame B except for the frame extending part C such as a veranda.

  The building wall structure by the building wall panel 41 for cooling and heating having the above configuration can be easily secured as a panel wall as a structural outer wall by configuring it as a PC panel with an exterior, and it can be greatly constructed by applying outside construction from the outside. Since it has a degree of freedom, it can be applied to a wide range of applications, including post-renovation and partial renovation, and small buildings.

  Also, during cooling and heating, cold and hot heat is radiated from the outer wall side into the room by forcibly flowing cold and hot water through the pipe 33 as a heat medium, so that the influence of outdoor weather conditions can be minimized. The problem of condensation due to air retention on the back side of the furniture when the furniture is arranged along the outer wall can be solved. In particular, since the building wall panel 41 for cooling and heating and the building frame B are thermally integrated by the filler 47, the cooling bridge phenomenon generated by the frame extending part C such as a veranda can be blocked, so-called The cold bridge problem that could not be solved even by the outer heat insulation method can be prevented, and both the additional structure by the housing extension C and the indoor living environment can be achieved.

  In this way, by configuring the building wall panel 41 for cooling and heating to be applied to the outer wall, it is difficult to achieve uniform heating, which is difficult to achieve by cooling and heating with the partition panel, without being restricted in construction due to the weight of the partition PC panel or the like. The indoor environment can be easily secured.

  In addition, as shown in FIG. 12, the building wall structure 51 in which the adjustment connecting means is incorporated in the exterior PC panel, the air conditioning building wall panel 51 is aligned with the building frame B by the adjusting connecting means. The outer wall can be built by filling and molding so as to be embedded by the filler 47.

  Specifically, after the building wall panel 51 for cooling and heating is fitted into the building frame B by lift means on the ground side, the level adjusting bolt 52 screwed to the lower end of the PC plate 42 via the insert fitting 53 is attached to the building frame B. The level is adjusted by the bolt 52 received by the side plate 54, and the upper part of the panel is fixed to the angle piece 56 on the building frame B side by the bolt 55 screwed to the upper part of the PC plate 42. Insulating material 43b such as urethane foam is blown into the gap, waterproofed with the sealing material 44b, and including the adjustment connecting means such as bolts 52, 55, angle piece 56, etc. Can be formed.

  In addition, by removing the heat insulating material 43 of the building wall panels 41 and 51 for air conditioning, it becomes possible to perform air conditioning including the outer space, and by adopting a so-called double configuration with a partition portion made of heat insulating material in between. The inside and outside of the wall panel as the outer wall can be individually controlled for heating and cooling. About these air-conditioning effects, it is clear that the same effect can be obtained in the case of a building wall structure in which the building wall panel for air-conditioning with the hollow wall body made of the two plates described above is applied to the outer wall. The description of is omitted.

  The building wall structure for cooling and heating according to the present invention enables low-cost and comfortable wall surface radiant cooling and heating, and is not limited to new construction of large-scale buildings, including small-scale buildings, renovation and partial renovation by post-construction, etc. It can be applied widely.
