Description

[Detailed explanation of the invention] This invention is mainly used for hot water supply and heating of residences, facilities, companies, etc.
Or a ceiling wall fixing device such as a panel type hot water storage tank for storing hot water supplied from a solar water heater or other heat source water heater for the purpose of industrial use. It is related to.

Conventionally, with this type of ceiling wall fixing device, the ceiling wall fixing metal fittings were fixed from inside the panel type hot water storage tank, etc., which made work inside the panel type hot water tank extremely troublesome, and it was difficult to securely fix it. In addition, in order to prevent the upper part of the side wall from bulging, measures were taken to use stainless steel round rods to pull the opposing side wall joints together, but the strength was weak and it was difficult to prevent the upper part of the side wall from bulging. It has been impossible to reliably prevent the upper part of the side wall from bulging.

Therefore, this idea was devised to solve the above-mentioned problems, and it uses two types of ceiling wall fixing brackets, a pair of inner ceiling wall fixing brackets and an outer ceiling wall fixing bracket, to fix a single side wall. In addition to making it possible to extremely easily and firmly fix both edge flanges of a single ceiling wall to the upper edge flanges and side wall joint fittings from the outside of a panel type hot water storage tank, etc.,
To provide a ceiling wall fixing device for a panel type hot water storage tank, etc., which uses the ceiling wall itself as a tensile member for the upper part of the side wall and can reliably prevent the upper part of the side wall from bulging due to an earthquake or the like.

The gist of this invention is that outward flanges are provided protruding from the adjacent side edges and upper edge of each single side wall that constitutes the side wall of a panel type hot water storage tank, etc., and the flanges on the side edges are butted against each other. A pair of side wall joining fittings with a U-shaped cross section are brought into contact with each other back to back from both sides, and one side is attached to the adjacent side edges and both end edges of each ceiling wall constituting the ceiling wall of a panel type hot water storage tank, etc. A flange and an outward flange having a downward hook-shaped cross section are provided protrudingly, and the flanges on the side edges are butted against each other and joined together, and the flanges on both end edges of each ceiling wall raccoon body are attached to the flanges on the upper edge side of each of the side walls. A pair of inner ceiling wall fixing metal fittings placed so as to be engaged with each other and extending between the lower side of the flange on the upper edge side of each single side wall and the outside of the upper edge of each side wall joint metal fitting, and the flanges on both edge sides of each single ceiling wall. This consists in properly fixing them with bolts and nuts via the outer ceiling wall fixing metal fittings which are hung horizontally on the outer sides of the side wall joining fittings of each single side wall.

An embodiment of this invention will be described below with reference to the drawings.

In the figure, numeral 4 indicates each single side wall that constitutes the side wall B of the panel type hot water storage tank A, etc., while 9 represents each single ceiling wall that constitutes the ceiling wall C of the panel type hot water storage tank A, etc., and each of these side walls The unit 4 and each ceiling wall unit 9 are each formed so that the inner layer 1 and outer layer 2 made of glass fiber reinforced plastic (hereinafter referred to as FRP) are filled with a heat insulating material 3 made of foamed plastic such as hard urethane foam. There is.

Outward flanges 5 and 6 are provided on the adjacent side edges and the upper end edge of each side wall unit 4 so as to protrude laterally at right angles to the surface of the side wall unit 4, and the flanges 5 on the side edge side A pair of side wall joint fittings having a U-shape in cross-section are provided with bent pieces 7 in the same direction from both sides of each flange 5 on the side edge side of the abutted side edges. 8 are placed back to back and joined with bolts and nuts (not shown).

On the other hand, outward flanges 10 are provided on adjacent side edges of each single ceiling wall 9 to protrude upward at right angles to the surface of the single ceiling wall 9, and both end edges of each single ceiling wall 9 have downwardly facing cross sections. Hook-shaped outward flanges 11 are respectively provided to protrude straight to the sides from the surface of the single ceiling wall 9, and the flanges 10 on the side edge sides are butted against each other and joined with bolts 12 and nuts 13.

The ceiling wall C is attached to the side wall B so that the flange 11 having a downward hook-shaped cross section on both end edges of each ceiling wall unit 9 engages with the flange 6 on the upper edge side of each side wall unit 4 formed in this way.
At the same time, a pair of inner ceiling wall fixing fittings 14 having an upper rod shape when viewed from the front are placed between the lower side of the flange 6 on the upper end edge side of each side wall unit 4 and the outer side of the upper end of each side wall joining fitting 8. Attach bolts 15 and nuts 16 only to each side wall joint 8.
Next, attach a screw to the upper side of the flanges 11 on both end edges of each ceiling wall unit 9 and to each of the outer bent pieces 7 of the side wall joint fittings 8 of each side wall unit 4 at the center in the longitudinal direction. An outer ceiling wall fixing fitting 18 having a letter-shaped shape when viewed from the side where the relief groove 17 of the side flange 5 of each ceiling wall unit 9 is provided on the upper side is horizontally mounted, and the both end flanges 11 of each ceiling wall unit 9 are installed horizontally. Two bolts 19 and nuts 20 are simultaneously tightened to the upper edge side 7 flange 6 of each side wall unit 4 and the flange 6 side of each of the inner ceiling wall fixing fittings 14 to fix them in a tight state. Bent piece 7 of side wall joint fitting 8
The bolts 2 and nuts 22 are tightened to fix the parts in a tight state.

Since this invention is constructed as described above, two types of ceiling wall fixing fittings, a pair of inner ceiling wall fixing fittings 14 and an outer ceiling wall fixing fitting 18, can be used to fix the inside of a panel type hot water storage tank A, etc., as in the past. The outward flanges 11 on both end edges of the ceiling wall unit 9 can be attached to the outward flanges 6 on the upper edge side of the side wall unit 4 and the side wall joint fittings 8 from the outside of the panel type hot water storage tank A, etc. very easily and firmly without having to perform fixing work. can be fixed to.

Moreover, the side wall unit 4 of the side wall B and the ceiling wall unit 9 of the ceiling wall C
is firmly fixed with two types of ceiling wall fixing fittings, and an outward flange 11 with a downward hook-shaped cross section is protruded from both ends of the ceiling wall unit 9, and this flange 11 is attached to the upper edge side flange 6 of the side wall unit 4. Combined with the fact that the ceiling wall unit 9 is placed so as to engage with the ceiling wall unit 9, the ceiling wall unit 9 itself serves as a tensile member for the upper part of the side wall unit 4, thereby ensuring that the upper part of the side wall unit 4 does not swell due to an earthquake or the like. can be prevented.

In addition, when fixing the ceiling wall unit 9 to the side wall unit 4, the fixing operation is extremely easy, excluding work inside the panel type hot water storage tank A, etc., and the upper part of the side wall unit 4 is prevented from swelling. In order to do this, the structure is significantly simplified without using a round bar to pull the space between the opposing side wall joint fittings 8, so that it can be provided at low cost and is extremely economical.

As explained above, according to this invention, not only can a single ceiling wall be fixed to a single side wall very easily and firmly from the outside of a panel type hot water tank, etc. using two types of ceiling wall fixing fittings, but also the ceiling wall The unit itself serves as a tensile member for the upper part of the side wall unit, and various excellent effects such as being able to reliably prevent the upper part of the side wall unit from bulging due to earthquakes etc. can be obtained.
