[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a heat storage panel board for heating and cooling that utilizes the floors and walls of buildings such as wooden, R, C, and reinforced concrete buildings, and a method for manufacturing the same. This invention relates to board frames.

(Prior art) The aspect of the present application, for example, the patent No.
The method invention of No. 428766 (Japanese Patent Publication No. 57-'37741) is that [a wire mesh (of a size slightly smaller than the internal dimension of the form) ( The upper and lower sides of the brass tube are sandwiched between the upper and lower sides by a wire mesh, and the brass tube body, except for the connection port of a single small diameter bent tube with good heat conduction, is bent in a meandering manner on a plane, and the brass tube body is slightly connected to the bottom of the formwork. Then, into this formwork, a heat storage mortar hydrate prepared by adding water and kneading a mixture of fly ash, quicklime, and Boltland cement with glass fiber or rock wool fiber added is poured into the mold, A method for manufacturing a board for a heat storage panel (hereinafter simply referred to as a board) in which a wire mesh for sandwiching the bent pipe body is embedded in the heat storage mortar and solidified into a flat plate shape. As an opening formwork,
Use a rectangular iron or wooden formwork with a square opening and a shallow bottom, pour the above hydrate into it, level the surface, and leave it to deaerate. After solidification, the formwork is removed and the product is made into a board, and a large number of the boards are connected and laid to form a floor or wall over a wide area.

(Problem to be solved by the invention: After that, for both iron and wooden items, a mold release agent is applied to the inner surface of the formwork, a heat-storage mortar hydrate is injected into the formwork, and even after solidification, the formwork is removed from the board. must be carried out, and in addition, reusing formwork requires considerable effort and time due to preparatory work such as removing mortar that has solidified and adhered during surface work. This hindered the reduction of labor costs and hindered the rationalization of board manufacturing prices. The purpose of the present invention is to stop the use of the above-mentioned formwork,
Steel Plate 9 Instead of using a board frame made of synthetic resin board, wood plywood, etc., after the mortar has solidified, we can create a board with a frame that is integrated with the board frame, allowing multiple boards to be connected for heating, cooling, etc. of floors and walls. When forming a heat storage panel, it is possible to easily ensure flatness over a wide area and save labor during manufacturing. The cement in the heat storage mortar hydrate or the heat storage mortar hydrate can be used as cement type (commercially available from Onoda Cement, Nitto Chemical, Nippon Steel Chemical Co., Ltd., etc.), gypsum type (marketed by Yoshino Gypsum Co., Ltd.), ceramic type (commercially available from Yoshino Gypsum Co., Ltd.), etc. (commercially available from Ube Industries, Ltd.), or by forming a double layer by pouring the self-leveling mortar onto the solidified mortar or heat-storage mortar hydrate. An object of the present invention is to provide a board with a frame for a heat-storage panel, a method for manufacturing the same, and a board frame, which improves the flatness of the upper surface and eliminates warping during storage after solidification.

(Means for Solving the Problems) The configuration of the present invention will be described below with reference to embodiments of the present invention shown in the drawings. [Board frame] In Fig. 1a, F is the board frame of the present invention, which is a steel plate with a thickness of about 0.3 to 1.0 sm, and is made of soft! It is made by processing synthetic resin moldings such as hard vinyl chloride made by extrusion molding into 4 sheets, or about 3 to 5 cm thick, or wood-based plywood about 5 tons+* to 121 mm thick. Pa is the upper horizontal frame, Fb is exactly the left vertical frame, Pc is the right vertical frame, Pd is the lower horizontal frame, and each frame in L is approximately 35 cm in height.
~50Illl, width 600IIIm, height 1700+n
It is framed in a rectangular shape of m in size and assembled into a board frame F by joining means such as welding, screwing, and gluing, and each frame has a channel, U-shape, L-shape, and ■-shape in cross section as shown in Figure 2 a. The two facing north and downward horizontal frames Pa, Fd and the left and right vertical frames Fb, Fc are made into a pair, and approximately in the center of the longitudinal direction of the outer surface thereof, there is a retaining section consisting of a continuous convex strip 1 and a concave iM2. Gobe K
a, Kb are arranged, and each protrusion 1 of Ca, Ch, and Cc of the various tongue-and-groove joints C shown in FIG.
Alternatively, grooves 2 are formed horizontally at the same height by bending with a press in the case of iron plates and mild steel plates, integrally formed during molding in the case of synthetic resin materials, and formed into a thin groove in the case of wooden plywood. The plate materials are bonded or bonded by gluing and grooving, respectively. 3
and 4 are respectively the top and bottom surfaces of the wide or narrow board frame F, 5 is the wide outer surface, S is the pouring space inside the board frame F, and Ta is the upper space surrounded by the top surface 3 of the board frame F. II,
Tb is the bottom opening surrounded by the bottom 4 of the board frame F, 6 is L
This is a through hole for inserting a tubular body such as a steel pipe described later, which is bored in the side surface of the horizontal frame Fa and the lower horizontal frame Fd. [Mortar layer and composition]
Next, as the mortar layer used in the present invention, the single layer shown in FIG. Patented heat storage mortar M, composition (3),
There is a heat storage mortar M1 composition (4) using commercially available self-leveler mortars S and L, and commercially available self-leveler mortars S and L. Among them, the heat storage mortar M type with compositions (2) and (3) is explained as follows: 10 volumes of short glass fibers or short rock wool fibers! 11%, fly ash 10-20% by volume
, quicklime 10% by volume, Boltland cement 60-70
Appropriate amount of water is added to the mixture and kneaded, but it is preferable to remove a part of it, or add cut pieces of metal or wire, for example. As with the idea described in Utility Model Publication No. 48-1185, concrete using gravel or crushed stone is used as a heat generating element, and as a result, it can be used for materials that are heavy and have low heat storage properties, or even lightweight materials such as lightweight foamed concrete. Due to the insulating properties of the air in the pores, the particles are thin and have high fluidity, unlike substances that impede heat conduction.

It is a material that is easy to pour into a wire mesh, makes it easy to remove any trapped air, and accelerates solidification due to the exothermic reaction of quicklime. Next, for composition (3), in place of Boltland cement in the heat storage mortar M, an appropriate self-leveling mortar material (fine sand, fly ash, etc.) from commercially available cement, gypsum, ceramic, etc. This is a heat-storage mortar made by kneading and kneading (some mixtures are available).In addition to the above properties, it also has the feature of automatically maintaining a flat surface during solidification and preventing warping during storage after solidification. Composition (5), the above composition (3
) or (4), if self-leveler mortar S, L is used in the entire pouring space S of board frame F, the unit price of the board will increase considerably because the price of self-leveler mortar material is currently relatively expensive. I'm afraid. For these, the fourth
The one shown in the figure is a two-layer type, and most of the pouring is done with Onkun mortar N of composition (1) or heat storage mortar M of composition (2), and only the top part is poured with composition (4). ), by pouring Le leveler mortar S, L, or heat storage mortar M of composition (3), results approximately equivalent to composition (3) can be obtained (J(). [Method for manufacturing a board with frame ]
(Part 1) As shown in Figure 3a, the manufacturing procedure for the framed board B is as follows: First, prepare a flat and thick underlay board E such as a flat iron plate in a part of the workplace, and apply a mold release agent. The applied t-side P
A non-adhesive synthetic resin sheet such as a polyethylene notebook is placed on the surface Ea of , a, or -, and the board frame F is placed on top of it. Next, a pipe body P such as a bent pipe 7 or a straight pipe 8 with a diameter of about 20 mm 1 a synthetic resin pipe or the like (not shown in FIG. In advance, attach a flat wire mesh 9 slightly sandwiched from the board frame F to the upper and lower surfaces or one side of the board using wire, etc., and use the ends of the wire to attach the upper surface of the underboard E. It is held in the pouring space S above the upper part of Ea, and at that time, the connecting end Pa (connecting ends 7a, 8a8b) of the tube P is inserted into each through hole 6 of the board frame F. Then, one type of mortar among the mortars having the above-mentioned compositions is poured into the pouring space S until the mortar reaches the upper opening Ta, and left to stand, solidifying with the tube body P embedded, as shown in Fig. 4a. Either a single mortar layer da is formed as shown in FIG. Pour and solidify, then composition (3),
Or (4), the mortar is injected until it reaches the upper opening Ta and solidified to form a two-layer mortar layer Mb. Thereafter, the board that has been solidified in close contact with the board frame F is removed and separated from the underlay board E with the frame, thereby completing a heat storage board Ba with a frame. (Part 2) Similar to Part I, first insert a heat insulating material 1G (for example, the product name Styrofoam etc.), and then place the pipe P with the wire mesh 9 set thereon in the same manner as above, or after placing the pipe P, place the same wire mesh 9 on top of it, and place the wire mesh 9 on top of it. 9. Wire mesh with stapler etc. The pipe P is fixed to the heat insulating material IO at the end. At this time, the pipe P is in direct contact with the insulation material 1o, so in the next step mortar is poured in and II! When the lower surface of the tube P is exposed from the bottom of the solidified mortar layer when IJ is formed, the heat source temperature in contact with the heat insulating material 10 becomes somewhat higher than when it is completely buried in the mortar layer Ma.
Although there is a risk of increased heat loss, it is not a practical problem when the water temperature is around 50 to 75 degrees, but if necessary, support it with wire etc. and connect the bottom surface of the pipe P with insulation material. It is sufficient to separate the surface of the IO and bury the entire tube P in mortar. Next, pour mortar in the same manner as in Part 1 of Part 1 to form a single-layered mortar layer Ma or a two-layered heat-storage mortar layer Mb, and remove it from the upper surface Ea of the underlayment plate E to attach a heat insulating material loading frame. A heat storage board Bb is obtained. [Panel installation method]
(Part 1) As shown in Figure 5a, a separate insulation material 14 is laid on two sides of the rough floor 13 made of plywood, such as the thickening 11, the joist 12, and what is commonly known as a control panel, and if necessary, use adhesive. Aratoko 13
The heat storage frame board Ba is placed on the second side of the 5th plate.
As shown in Fig.
It is fixed to the separate heat insulating material 14 with double-sided adhesive tape or the like, and at that time, protrusions l and recesses corresponding to the engaging parts Ka and Kb forming the supporting joint C are attached to the adjacent left vertical frame Fb and right vertical frame Fc. For those with grooves 2, the grooves 2 are fitted, and for those without connecting ends Pa of the pipe body P, there is an engaging portion Ka that forms a supporting joint C between the upper horizontal frame Fa and the lower horizontal frame Fb facing each other. Convex line 1 and concave line 1 corresponding to Kb
For those with 42, fit them together in the same way as described in item 2. However, if necessary during the above-mentioned fitting process, use an adhesive or the like to secure the engaging part of the support joint C to strengthen the connection. A panel Q shown in C is formed. In addition, if the connecting end Pa of the pipe body P is exposed,
Connecting the connecting end 7a and the opposing connecting ends 8a and 8b,
Alternatively, the connecting ends 8a and 8b may be connected at the U-bend 15 to form a flow circuit for the entire pipe body. In the panel Q in which a plurality of framed heat storage boards Ba are laid as described above, there is room for the joints between each board and the surrounding areas, so if there are joints there, the self-leveler mortar 5.1. , and after drying, perform a level finish with G, L, and bond.Insulating material is laid on the connecting end Pa and the staggered area, and then mortar is poured in to seal it. After that, the panel P and the rough floor 13 are firmly connected and integrated using wood screws or concrete nails. (Part 2) As shown in Figure 5 S and Figure 5 D, same as Part 1, Ohiki 11
, the bottom opening Tb onto the floor consisting of the joists 12 and the rough floor 12.
A heat storage board Bb with a heat insulating material frame and a heat insulating material 10 packed inside is directly laid to form a panel Q shown in FIG. The other procedures and methods are exactly the same as Part 1 above.

(Effects of the Invention) (1) 9 According to the method for manufacturing a heat storage board with a frame of the present invention, a mold that is used repeatedly as in the past is not used, and after pouring mortar, the board frame F itself is covered with a layer of mortar. And one with the side,
Since it can be used to form the panel P, there is no need to remove and clean the repeatedly used formwork, or apply a mold release agent, which helps save labor during production. (2) In the framed heat storage board of the present invention, the wide or narrow top surface 3 and bottom surface 4 of the board frame F, as well as the wide side surface 5, are smooth and accurate in terms of angle, making it easy to lay the panel Q. Since it is easy to join and level the outer surfaces 5, etc., the construction time can be dramatically shortened. Furthermore, when the supporting joint C is employed on the side surface 5, the leveling and the integral structure of the panel Q can be particularly strengthened. (
3) Since the heat storage board Bb with a heat insulating material preparation frame has the heat insulating material IO built-in in advance, it is possible to save the trouble of laying the separate heat insulating material 14 on mW, and the board can be placed on the top surface of the flat rough floor 13. Frame F
Since the flat bottom part 5 of the machine can be placed directly on the machine, the effort of leveling the machine when placed on the floor can be greatly reduced. (4) The board frame F is made of a bent metal sheet pressed or an extruded synthetic resin material, and is easily and precisely made and is inexpensive, compared to conventional formwork. It doesn't affect the cost of panel configuration much, and you can save money by streamlining the work.
Overall cost savings are possible.
