Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a horizontal support device for a heat exchanger installed in a panel-assembled constant temperature tank.

[Conventional technology and its problems]

Recently, a large tank has been constructed by assembling a panel body with FRP plates attached on both sides of a heat insulating material made of plastic foam sandwiched in the field construction, and this is a panel type heat storage tank, It is widely known as a panel aquarium, an assembling aquarium, an assembling tank and an assembling type warmer.

By the way, such panel-assembled constant temperature tanks generally store water, hot water, etc., but if necessary, multi-tube heat exchangers or coil heat exchangers, and in special cases, heat pipe heat exchangers (See, for example, JP-A-60-34381 and JP-B-62-12109).

However, if these heat exchangers are simply installed in a conventional pipe-assembled thermostatic tank, the panel body is relatively vulnerable. There was a possibility that cracks and the like would occur in the tank side plate due to the overturning impact.

In addition, regarding a support device for a lower part of the internal structure in the low-temperature tank, a support arm is horizontally mounted on a concrete layer via a plate-like welded wall or a heat insulating layer, and the earthquake-resistant device supports the internal structure on the support arm. Is known (for example,
See JP-A-61-156799).

However, in such a device for supporting an internal structure in a low-temperature tank, a plate-like welding wall (membrane wall) in which a horizontal support arm or a support plate forms an inner surface of the tank.
The FRP board is attached to both sides of the foam body, which impairs the water sealing property, which is one of the features of the panel body. Aside from walls, it cannot be used with FRP boards without back reinforcing members embedded in the panel body.

[Means for solving the problem]

Therefore, the present invention was devised in order to solve such a problem, and the gist of the invention is (1) to construct a panel body in which a plastic foam is sandwiched and FRP boards are attached to both sides thereof. In the constant temperature tank, a heat exchanger is installed in the constant temperature tank, a support plate that surrounds the heat exchanger and prevents overturning is provided horizontally, and the support plate is provided on the inner surface of the tank side plate.

[Effect of the invention]

 According to the present invention, the following beneficial effects can be expected.

Since the heat exchanger installed in the constant temperature tank was horizontally surrounded by the support plate supported by the shelf, even if the constant temperature tank encountered an earthquake, the heat exchanger did not fall in any direction. The side plates are not damaged by the heat exchanger.

Since the heat exchanger was surrounded by a horizontal support plate, the load of the heat exchanger normally did not act on the side plate, and the shelf plate supported only the support plate. This is convenient for the shelves fixed by the provided overlay and also for the FRP plate side plates that are more fragile than the steel plates.

The supporting plate is detachably supported on the side plate by a shelf plate fixed by overlays provided on the upper and lower surfaces, so that the mounting plate is not provided, and an inexpensive shelf plate having an L-shaped cross section is used for plastic foaming. The water sealability of the panel body with the FRP plate attached to both sides of the body is not impaired, the strength of the FRP plate is not impaired, and the construction of the tank is simply an inexpensive L-shaped shelf with an inexpensive section. Thus, the support plate can be easily carried in and out of the tank when the support plate is assembled into the tank by the shelf having the L-shaped cross section.

In particular, the work of fixing the upper and lower surfaces of the shelf plate having an L-shaped cross section by overlay in the tank (construction work of the tank) can be extremely easily performed because of the belt-like shelf plate.

In addition, since bolts are planted on the shelf in advance and the support plate is fixed by the bolts, there is no need to tighten the bolts while holding the bolts.
