Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a heat storage tank provided in a foundation pit of a building.

[0002]

2. Description of the Related Art As is well known, a heat storage tank in a building cooling and heating system is most commonly installed using a foundation pit. In this case, a frame such as a foundation beam is used as a partition wall. Ordinarily, the tank is divided into a plurality of water tanks.

FIG. 3 shows an example of such a heat storage tank. In FIG. 3, reference numeral 1 denotes a foundation beam (including a foundation small beam), 2 denotes a foundation slab, 3 denotes a slab of the lowest floor, and in the illustrated example, the foundation beam 1 is used as a partition wall and four water tanks 4 (4 a to 4 a). 4d), the base beams 1 are provided with communication holes 5 at different positions, so that the water tanks 4 communicate in a meandering state from the inflow side to the outflow side as shown by arrows in the figure. Is formed.

[0004] Such a heat storage tank is called a complete mixing type multi-tank connection method. In order for the heat storage tank to have sufficient heat storage efficiency, mixing is performed in each of the water tanks 4 without causing temperature stratification. Water tank 4 on the inflow side
It is necessary that the temperature difference between the water tank 4a and the water tank 4d on the outflow side be as large as possible. For this purpose, as many water tanks 4 as possible (10 to 15 tanks or more are preferable).
It is said that it is necessary to make the water flow path long enough. When it is not possible to divide into a large number of water tanks 4 using only the original foundation beams 1 as shown in FIG. 3, for example, as shown in FIG. By partitioning the water tank 4 into small water tanks, about 10 water tanks are secured as a whole, and the water passage is made longer.

[0005]

However, in order to provide the above-mentioned partition wall 6 in the foundation pit, the partition wall 6 is made of concrete and constructed integrally with the foundation beam 1 at the stage of foundation work, or After the foundation work is completed, the partition wall 6 will be installed again, but in any case, the cost will increase considerably, which is not preferable.

In order to improve the efficiency of an existing heat storage tank that is already in operation, the above-mentioned partition wall 6 may be added. However, when such repair work is performed, the partition wall 6 is not used.
With the increase in the number of the water tanks 4, repair work for the existing heat insulating material installed on the inner surface of each of the water tanks 4 also becomes necessary, so that it is inevitable that the repair cost will increase.

[0007] In view of the above circumstances, the present invention provides an effective heat storage tank which can be easily partitioned into a large number of water tanks without being restricted by the form of the foundation, and which can secure excellent heat storage efficiency. The purpose is to:

[0008]

According to a first aspect of the present invention, a frame such as a foundation beam is provided in a foundation pit of a building in a state of being partitioned into a plurality of water tanks as partition walls and provided on the partition wall. A heat storage tank in which a series of meandering water passages communicating between the water tanks are formed by the communication holes, wherein the water tank is further partitioned by a partition wall, and the partition wall is formed by a sheet material. A communication hole is provided at a predetermined position of the sheet material, and both side edges of the sheet material are fastened to the columns erected along the partition wall, thereby stretching the sheet material between the columns. is there.

According to a second aspect of the present invention, in the first aspect of the present invention, the upper and lower ends of the strut are pressed against the upper and lower slabs of the foundation pit so that the strut is allowed to stand between the slabs. It becomes.

According to a third aspect of the present invention, in the first or second aspect of the present invention, the sheet member is provided with an inspection opening which can be opened and closed by a fastener.

[0011]

1 and 2 show an embodiment of the present invention. In the heat storage tank of this embodiment, each water tank 4 partitioned by the foundation beam 1 is further partitioned by a partition wall 10 like the one shown in FIG. 4, and the partition wall 10 is formed by a sheet material 11. It was made.

That is, in the heat storage tank of the present embodiment, two columns 12 are respectively provided on both sides of the position where the partition wall 10 is to be installed along the foundation beam 1 as a partition wall. The side edges of the sheet material 11 are tightly bound by the rope
A sheet material 11 is stretched between them to form a partition wall 10.

The above-mentioned sheet material 11 is naturally impervious, and for example, the one used as a tent is optimal. A communication hole 14 is formed at a necessary portion of the sheet material 11, and an inspection port 15 for maintenance work is provided so as to be opened and closed by a fastener (zipper) 16. The inspection port 15 is preferably of a size that allows a worker to easily pass, for example, 500 mm × 1500 mm, and three sides thereof may be opened and closed by a fastener 16 as shown in FIG. Also,
A small gap 17 for draining is secured between the lower edge of the sheet material 11 and the foundation slab 2, and the ventilation between the upper edge of the sheet material 11 and the slab 3 is secured without blocking. I do.

A stainless steel pipe member is used for the support 12 in consideration of rust prevention. At its upper and lower ends, abutment plates 18 are screwed or biased to the tip end by springs. The support columns 12 are the backing plates 1
8 is pressed against the surface of the heat insulating material 19 attached to the surface of the base slab 2 and the slab 3 to be free standing in a state of being stretched between them, so that the desired heat insulating material 19 can be obtained without any damage. It can be built very easily at the location, and can be easily removed and repositioned as needed.

As described above, in the heat storage tank of the present embodiment, the partition wall 10 is formed of the sheet material 11, so that the partition wall 10 can be freely installed at a desired position without being restricted by the foundation frame. The water tank 4 can be partitioned, and therefore, excellent heat storage efficiency can be secured. The above-mentioned partition wall 10 can be extremely easily installed only by stretching the sheet material 11 between the supporting columns 12 which are self-standing between the upper and lower slabs 2 and 3, and thus is shown in FIG. 4. The labor and cost can be remarkably reduced as compared with the case of installing a conventional general partition wall 6 made of concrete or the like, the heat insulating material 19 is not damaged, and the position can be changed or changed as necessary. It is very effective because it can be removed freely.

Further, since the sheet material 11 can be folded small, and the length of the column 12 is only equivalent to the height of the base pit, and none of them has much weight, they are In addition to being able to be carried into the foundation pit from the manhole without any trouble, the carrying-in work, the work of erection of the support pillars 12, and the work of stretching the sheet material 11 can be performed very easily only by human power. Since the heat insulating material 19 is not damaged as described above, it is optimally applied particularly to a case where the existing heat storage tank is modified so as to be partitioned into a larger number of water tanks.

Further, when a conventional general concrete partition wall 6 is provided, it is necessary to provide a drainage hole or a vent, but as described above, the lower and upper edges of the sheet material 11 and the slab 2 are not provided. , 3 need not be provided. Further, by providing the inspection port 15 that can be opened and closed by the fastener 16 as described above, the opening 15 having a large size can be secured without any trouble, which is extremely convenient when performing maintenance work in the heat storage tank.

It is most preferable that the upper and lower ends of the column 12 are pressed against the upper and lower slabs 2 and 3 so that the column 12 is made to stand by itself, but is not necessarily limited to this. As long as it is formed by the sheet material 11, another structure such as fixing the support to the frame may be adopted. It goes without saying that the form and scale of the heat storage tank are arbitrary.

[0019]

In the heat storage tank according to the first aspect of the present invention, a partition wall for partitioning the water tank is formed of a sheet material, and both side edges of the sheet material are tightly connected to the columns, and are stretched between the columns.
A partition wall can be installed at a desired position without being restricted by the foundation frame and partitioned into a large number of water tanks, so that excellent heat storage efficiency can be secured, and a partition wall made of a conventional general concrete structure or the like can be obtained. The installation work can be performed extremely easily compared to the case of installation, the labor and cost can be significantly reduced, and the position can be freely changed and removed as necessary, Particularly, it is optimally applied to a case where a partition wall is added to an existing heat storage tank.

In the heat storage tank according to the second aspect of the present invention, the upper and lower ends of the column are pressed against the upper and lower slabs so that the column is self-supported in a state of being stretched therebetween, so that the column can be built very easily and if necessary. Relocation and removal can be performed without any trouble, and the heat insulating material on the slab surface is not damaged.

The heat storage tank according to the third aspect of the present invention is provided with an inspection port which can be opened and closed by a fastener in the sheet material, so that a large inspection port can be provided without any trouble, which is convenient for maintenance and inspection work.
