[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for applying heat insulating material to a heat storage tank wall for forming a heat insulating layer on a heat storage tank wall constructed underground of a building or the like.

[0002]

2. Description of the Related Art In a heat storage tank constructed underground of a building or the like, a heat insulating layer is formed on an inner wall of the heat storage tank in order to enhance heat retention. As a method of applying a heat insulating material to form this heat insulating layer, conventionally, as shown in FIGS.
A pair of plywoods 36, 36 are opposed to each other via a predetermined concrete placing space 37 by a fastening member 35 comprising a cone 31, a cone 32, a foam tie 33, a rib washer 34 and the like. A construction method is practiced in which a concrete is cast in the installation space 37 to construct a heat storage tank wall, and then a heat insulating material is adhered to the inner wall surface of the heat storage tank with an adhesive. The plywood 3
A heat insulating material is previously adhered to the inner surfaces of the heat storage tanks 6 and 36, and a concrete is poured into the concrete casting space 37 to construct a heat storage tank wall and the heat insulating material is fixed to the heat storage tank inner wall surface. Construction methods are also being implemented.

[0003]

However, in the conventional heat insulating material construction method, it is necessary to remove the plywood formwork after the concrete is cast, and the fastening wall 3 is attached to the concrete wall.
Since a hole was formed in the portion where the 5th cone 32 was mounted, the hole had to be filled with a filler, and the construction work was complicated and time-consuming.
In addition, since the heat insulating material is only attached to the concrete wall surface with an adhesive or fixed at the time of placing the concrete, there is a problem that the heat insulating material is easily peeled off from the concrete wall surface.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to eliminate a formwork, fill a hole with a filler, and the like, thereby simplifying a construction work. An object of the present invention is to provide a method for applying heat insulating material to a heat storage tank wall, which can be performed in a short time and can effectively prevent the heat insulating material from peeling off from the heat storage tank wall.

[0005]

In order to achieve the above-mentioned object, a method for installing a heat insulating material on a heat storage tank wall according to the present invention is to arrange and fix a highly rigid groove member on a floor slab, and to fix the upper and lower portions and both sides. Forming a protrusion or a groove to be fitted with this portion, forming a plurality of insertion holes penetrating in the vertical direction, and forming a connecting member mounting portion around the insertion hole, a foam synthetic resin dam plate member. The weir portion is inserted into the groove member, sequentially connected vertically and horizontally to be erected, and rigid bar-shaped members arranged at predetermined intervals in the horizontal direction are inserted into the insertion holes of the connected foam synthetic resin dam plate members. While forming, the both ends of the connecting member were positioned at the connecting member mounting portion, and the rigid bar-shaped member was inserted through the annular portions or the insertion holes formed at the both ends, and were opposed to each other via the space for concrete placing. A predetermined position in the vertical direction of the rigid rod-shaped member is set by the connecting member. Constitute a binding concrete formwork,
By casting concrete in the concrete casting space, a heat storage tank wall is constructed, and at the same time, a heat insulating layer is formed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for constructing a heat insulating material according to the present invention will be described with reference to the drawings, taking as an example a case where a heat storage tank 1 is constructed under a building.

As shown in FIG. 1, first, a plurality of reinforcing bars 4 are arranged at predetermined intervals from a floor slab 2 to a ceiling slab 3, and the surroundings of the reinforcing bars 4 are concreted by the heat insulating material construction method of the present invention. To form the heat storage tank wall 5 and simultaneously form a heat insulating layer.

Next, a heat insulating material 6 is adhered to the surface of the floor slab 2 and the ceiling slab 3 in a region surrounded by the heat storage tank wall 5 by a conventional heat insulating material construction method, and thereafter, the entire inner wall surface of the heat storage tank 1 is waterproofed. The heat storage tank 1 is completed by attaching the material 7.

Next, a procedure for constructing the heat storage tank wall 5 by the heat insulating material application method of the present invention will be specifically described.

First, as shown in FIGS. 2 and 3, groove members 8 made of steel or the like are arranged in two rows in parallel on the floor slab 2 and fixed. For example, an insertion hole is formed in the bottom portion of the groove member 8, a peg is inserted into the insertion hole, and the fixing member is fixed by striking the floor slab 2. The groove member 8 is not limited to a metal member, and may be a synthetic resin having high rigidity.

Next, from the groove member 8 to the ceiling slab 3, a foam synthetic resin dam plate member 10 made of styrene foam or the like.
Are fitted on the groove member 8 and sequentially connected vertically and horizontally to be erected.

The seams between the foamed synthetic resin damping plate members 10 may be in any shape generally used, that is, a spliced joint, a real spliced seam, or the like. Since it is easier to construct and integrate the synthetic resin damping plate member 10 to be integrated, it is preferable to use the actual joining.

In this embodiment, as shown in FIG.
Protrusions 1 on the upper and one side of the foam synthetic resin dam plate member 10
3 is formed, and a groove 14 to be fitted with the projection 13 is formed in the lower part and the other side part. As shown in FIG. 4, a plurality of insertion holes 11 penetrating in the vertical direction are formed in the foam synthetic resin dam plate member 10 at predetermined intervals in the horizontal direction. Further, as shown in FIG. 5, the periphery of the insertion hole 11 of the upper projection 13a of the foam synthetic resin dam plate member 10 is connected to a connecting member 15 described later.
Are cut off so as to be able to be attached to form a connecting member attaching portion 16.

In addition, while forming the weir portion 12 by vertically arranging the foam synthetic resin weir plate members 10 vertically and horizontally, the connecting member 15 having high rigidity is appropriately inserted.

As the connecting member 15, for example, as shown in FIG.
As shown in FIG. 7, a metal plate member 20 having insertion holes 21 formed at both ends thereof can be used. Here, the inner diameter of the annular portion 19 or the insertion hole 21 at both ends is substantially the same as the outer shape of the rigid rod-shaped member 9 described later, and the center distance of the annular portion 19 or the insertion hole 21 at both ends is a rigid rod-shaped member opposed to each other. 9 is substantially the same as the distance between the axes.

The rigid rod member 9 is made of steel or the like.
It may be hollow or solid, and its cross section is circular.
Any shape such as a rectangle may be used.

The rigid rod-like member 9 is inserted into the insertion hole 11 of the foam synthetic resin damping plate member 10 made of styrene foam or the like and the annular portion 19 of the connecting member 15 so that the opposing dam portion 1 is formed.

After constructing the concrete form in this manner, the concrete is cast in the concrete casting space 17 to construct the heat storage tank wall 5 and at the same time as the foam synthetic resin dam plate member 10. A heat insulating layer is formed.

Here, as a method of constructing the concrete formwork, the method in which the rigid bar-shaped member 9 is inserted after all of the foam synthetic resin damping plate members 10 have been previously described has been described in detail. The weir plate member 10 is arranged in only one stage, and the rigid rod-shaped member 9 and the connecting member 15 are inserted therethrough.
Alternatively, a number of rigid rod-like members 9 may be first erected at predetermined intervals, and a foam synthetic resin dam plate member 10 and a connecting member 15 may be attached thereto.

[0020] As described above, the heat insulating material construction method of the present invention comprises:
The formwork after concrete casting is also part of the heat storage tank wall 5,
Since the foam synthetic resin damping plate member 10 has the role of a heat insulating material, it is not necessary to remove the formwork, fill the hole with the filling material, etc., and the construction work is greatly simplified and can be performed in a short time. can do.

Since a predetermined position in the vertical direction of the rigid rod-shaped member 9 penetrating the synthetic resin dam plate member 10 is connected by the connecting member 15, the heat storage tank wall 5 forms a foam synthetic resin dam plate member as a heat insulating material. 10 does not peel off.

As the waterproof material 7 to be adhered to the entire inner wall surface of the heat storage tank 1, a polyolefin sheet such as polyethylene or polypropylene, a rubber sheet, a polyvinyl chloride sheet or the like can be used. . Instead of attaching the waterproofing material 7, an epoxy resin-based or urethane resin-based paint is applied or sprayed on the entire inner wall surface of the heat storage tank 1, or a cement mortar mixed with acrylic disperse is applied, for example. It may be waterproofed. Insulating materials for floor slabs and ceiling slabs may also be formed by the method of the present invention.

[0023]

According to the method for applying heat insulating material to the heat storage tank wall of the present invention, the formwork after concrete casting is also used as a part of the heat storage tank wall, and the role of the heat insulating material in the foam synthetic resin dam plate member. Since it is provided, it is not necessary to remove the formwork, fill the hole with the filler, and the like, and the construction work is greatly simplified and can be performed in a short time.

Further, since the rigid rod-shaped member penetrating the foam synthetic resin dam plate member is connected by the connecting member, the foam synthetic resin dam plate member as a heat insulating material does not peel off from the heat storage tank wall.
