Abstract

PURPOSE: To finish the surface well while keeping the surface side planarity of a framed board by forming a clamping space having regulated board thickness using a collapsible metal die plate and forming the side and intermediate die plates abutting on the side opening of a board frame with the flat plane of metal plates. CONSTITUTION: A board frame F is assembled by welding curved iron plate or soft copper plate rectangularly or combining die members of extruded aluminum or alluminum alloy rectangularly and then it is secured with tap pin screws to form a frame B. Mortar pouring openings Po are made by cutting one or the opposite end parts or the central part of upper frame Fa or vertical frames Fb, Fc or at a plurality of positions of the side face 5 and/or the upper face 3. Alternatively, one of the upper frame Fa or vertical frames Fb, Fc can be bonded later to other part of a frame J and at the time of pouring mortar, the upper frame Fa is removed so that entire opening Ja of the frame serves as a mortar pouring opening Po. A large quantity of mortar M is poured in a short time along the breathwise direction of the opening and filled forcibly around a tubular body from a metal mesh and then it is degased under stationary state.

Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a vertical pouring method for manufacturing a retentive board with a frame for heating and cooling panels that utilizes the floor of a building, etc., and a method for manufacturing the same. The present invention relates to an assembly type formwork, and a structure of a board frame of a framed heat storage board constituting a panel.

(Prior art) The invention of Japanese Patent Application No. 1-274029, which was invented and filed by this applicant before the present application, is the same as the present invention, for manufacturing a heat storage board with a frame for a heating/cooling panel. At this time, a frame board was placed directly on top of a flat metal plate or other underlayment board, and fluidized mortar was poured into the large opening at the top and allowed to harden.

(Problem to be solved by the invention) In the above method, the upper opening side is placed on the surface of the framed board when assembled into a panel, but the mortar solidified surface of the upper opening with a large area is It is surprisingly difficult to achieve a flat surface that maintains horizontality and a beautiful solidified surface. It was difficult to obtain it because of F-flat, and it required skill. Therefore, in the described invention, various improvements have been made to the mortar to be poured.In particular, self-referrer mortar containing various fluidizing agents with excellent self-smoothness is used, the mortar layer is divided into two layers, and an upper opening is formed. The fluidizing agent has a self-smoothing property as well as a self-smoothing property. As the name suggests, it retains its fluidity for a long time, so it takes time to solidify, and the flatness and surface finish are not perfect. The problem is that it becomes a burden on the HF2 by making it 1 dFt. The purpose of the present invention is to reliably maintain the flatness of the front side of a framed board that forms the surface for a heating/cooling panel, to make it possible to finish the surface well, and to reduce the time required for assimilation. The purpose of the present invention is to provide a vertical pouring method for manufacturing boards with frames for heating and cooling panels using prefabricated formwork, which does not take a long time, and to provide prefabricated formwork and boat frames used in the process. .

(Means for Solving the Problems) Hereinafter, the configuration of the present invention will be described with reference to embodiments of the present invention shown in the drawings. [Board frame] In Figure 1 a, F
is a board frame of the present invention, with a thickness of 0.3 mm to 1.0 mm.
By assembling and fixing bent front and rear iron plates or mild steel plates into a rectangle by welding, or by combining extrusion-molded aluminum or aluminum alloys with a thickness of about 2 to 3 mm into a rectangle similar to the above. The frame is assembled and fixed with tapping screws to form the frame B. Pa is the upper frame, Fb, Pc
are the left and right vertical frames, Fd is the bottom frame, and each layer has a thickness of about 35 to 50 m5. Width approx. 1700mm, height 6
The cross section of each layer is the same shape as a channel, U-shape, L-shape, I-shape, etc. as shown in Figure 5 a, b, and c, and the opposing upper and lower Both frames Fa, Fd and both left and right vertical frames Fh, Pc are made into a pair, and engagements K Ka , K b are provided from the convex line I and the groove 2 of the through, approximately in the middle of the longitudinal direction of the outer surface of the husband, etc. of the various tongue-and-groove joints C shown in FIGS. , may be attached integrally with each other, or may not be attached, and may be formed flat. Next, 3 and 4 are respectively the top and bottom surfaces of a wide or narrow board frame F of about 35 to 50 openings, 5 is a side surface, Po is one of the mortar injection ports which is a main part of the structure of the present invention, One end of the upper frame Fa or the vertical frame Fb, Pc (see Figure 2 a in the case of the upper frame), or both ends, or the center, or the upper surface 3 of multiple positions thereof, or the upper surface and Either by making a cut into the side surface 5 or making it possible to fix one of the upper frame Fa or the vertical frames Fb, Fc to the other part of the frame J, and when pouring mortar, the above-mentioned Upper frame Pa
etc., and set the entire frame opening Ja, which was completely opened by the above removal, as a mortar injection port Po, and from there, Taiso's mortar M was injected in a short time along the width direction of the opening. If necessary, use a protruding rod or the like to forcibly fill the mortar M from the wire mesh 9 to the circumference of the pipe P, and then leave it to stand to solidify by degassing. It is possible to cover the part Ja with the upper frame Fa or the like and fix it to the other part of the frame J by welding or by screwing in a self-tapping screw (?J42 Isusancho).

S is the mortar inflow space inside the port frame F, but a part of it actually consists of the undisclosed material lO described below and the pipe P that channels hot and cold water for heating and cooling. Hold the tube P at
It is also a space for accommodating a wire mesh 9 that protects the strength of the solidified board B and prevents it from warping. Next, Ta and Tb are
Left and right side openings 6 surrounded by the side surfaces 5 of the board frame F, respectively;
is a through hole through which the connecting end Pa of the pipe body P is inserted, and if it is in a horizontally long rectangular state or a rectangular boat frame F (not shown) is assembled into the prefabricated formwork A, it is inserted into one of the left and right vertical frames Fb and Fc. (Left below) Or on the top surface 3 of both sides, don't do too much quick work, or
Assemble the board frame F into a vertically long rectangle; 6. .

When assembling into the frame A, a plurality of holes are formed in the upper surface 3 of the L frame Fa, and the connecting ends Pa (described later) of the tube body P are inserted through the vertical frames Fb, Fc of the board frame F, or the upper frame Fa. Expose from side 3 of [Assembling type formwork] In Fig. 3, E is a metal or hard synthetic resin, or a prematurely laid underlayment form such as wood plywood, which can be horizontally attached to a rectangular foundation surface, etc., or a board frame F.
The mortar injection port Po side of the upper frame Fa or one of the vertical frames Db and Dc is inclined slightly higher and placed on the foundation surface or the like. Da, Db is J Yumi lower f! 1. A side template made of a metal plate similar to the formwork for the left and right concrete turns, whose bottom part was placed on one of the Ifi plates E and held vertically above the , are provided with deformation prevention ribs D, , D, etc. on the outer surface of each to prevent warping. Next, 6 is an intermediate template made of one or more metal plates, and a plurality of board frames F equipped with tubes P and wire mesh IO are divided and sandwiched between the left and right side templates Da and Db. Therefore, it is placed between adjacent board frames F. In addition, the bolt holes drilled at the same heights at the top, middle, and bottom of both sides of the side template DaDb and each intermediate template G are for binding and fixing the assembled prefabricated formwork A. This is a through hole for inserting a long bolt for fixing. Next, H is applied to the upper surface of the lower template E between the left and right side templates Da and Db, between the side templates Da and Db and the intermediate template G, or between the intermediate templates G. A spacer on which a horizontal bottom part is placed and interposed, and is made of a metal or synthetic resin material with a U-shaped cross section, or a wooden square lumber, etc., and is used as a side template Da.

Either match the length of Db, or arrange several short ones appropriately, and form a sandwiching space Q above them. Incidentally, on the upper surface of this spacing member H, for example, when the board frame F is assembled into the prefabricated formwork A in a vertically long state, there is a connection end of the tube P that protrudes outside the frame of the upper frame Fa of the board frame F. An insertion hole H3 into which Pa is inserted may be provided. In addition, the retaining angles E, E, which are made of metal templates fixed by welding or the like to the -E surface of the lower template E, are set so that the distance between them is set in advance by a predetermined number of boat frames F and intermediate templates G. Since it is fixed according to the sum of the thicknesses, the outer surfaces of the bottoms of the left and right side templates Da and Db are brought into contact with the side surfaces of the retaining angles E, E, and the spacing material H is applied. By sandwiching the intermediate template G during the process, a sandwiching space Q into which the board frame F is inserted can be easily formed. [Status of the board frame before pouring mortar] In Fig. 7, 7 and 8 are installed in the pouring space S of the board frame F, and have a diameter of approximately 20 mm.

Place it horizontally on an appropriate flat foundation surface, or the upper frame Fa of the board frame F, or the vertical frame Fb.

Place the mortar injection port P0 side of Pc slightly higher, then place the left side template Da on the L side of the underlay template E, and place the lower side of the left side (outside) on the underlay. Apply it to the vertical side of the mold retaining angle E fixed to the bottom plate E, then apply the left side of the spacing material H placed on the bottom template E to the right lower side of the side template Da, and then Place the left side of the lower part of the first intermediate template G on the right side of the spacer F (), apply the left side of the next interval retainer H to the lower side of the intermediate template G, and then is the spacing material 1
], repeating the operation of applying the intermediate IfI plate G one after another, and finally apply the left side of the right side template Db to the right side of the rightmost spacing member H, and place the right side of the lower part on the right side of the right side template IE. By bringing it into contact with the vertical left side of angle E, set α
After the assembly of the formwork A is completed, a plurality of (or a single) sandwiched spaces Q are formed into which the board frame F is fitted (in the case of only one intermediate formboard G, the remaining second The subsequent operations are unnecessary, and in the case of only the left and right side templates Da and Db, H-pieces of spacing members are sufficient).

After that, separately connect the pipe P and the entire wire mesh to the above-mentioned sandwiched space Q.

The board frame F equipped with the heat insulating material IO is fitted from above or from the side with the upper frame Fa facing upward, and the left and right side templates Da and D are fitted.
Insert long bolts into the bolt holes drilled at the same height and horizontal position on the top, middle, and bottom of intermediate template G and tighten the nuts to form the board frame F into an assembly type mold. Attach firmly to frame A, and attach both sides of each board frame F to side templates Da, Db,
Alternatively, a pouring space S is formed which is surrounded by the side surface of the intermediate template G and is surrounded by a flat parallel surface to the inside of the board F. In addition to the above, the board frame F may be installed as appropriate during the assembly operation of the prefabricated formwork A.
Apply a mold release agent for cement work on the surfaces of b and intermediate template G,
It is also desirable to apply it in advance. (Injection of mortar M)
In the above state, mortar hydrate, which has been mixed and adjusted to have appropriate fluidity, is poured into the upper frame Fa of each board frame F or from one or more mortar injection ports Po of one of the vertical frames Db and Dc. Inject mortar M. As the above-mentioned mortar M hydrate, patent No. 142876 developed by this applicant
6 (Japanese Patent Publication No. 57-37741), heat-storage mortar Ma prepared by adding water and kneading a mixture of fly ash, quicklime, and Portland cement with glass fiber or rock wool fiber added, or ordinary mortar N , or by adding a self-leveler (S, L,) agent with excellent self-smoothness to the above two types and injecting self-leveler mortar S, L, etc. with improved self-smoothness, the mortar M of husband etc. , flows from the injection port Po into the sandwiched inflow space S with a width of about 35mm sandwiched between the side plates Da, Db or the intermediate template G inside the board frame F, and flows into the lowermost frame Fd at the bottom. Starting from the inside of the inflow space S, gradually filling the inflow space S,
If there is a heat insulating material to, it is also injected into the concave groove 16 from around the pipe P through the board frame, and the height is about 600 mm when the board frame is installed horizontally, and about 17 mm when it is installed vertically.
If a rectangle with a height of 00 m5 is incorporated, a narrow space with a height of approximately 90 m5 will be filled up to the top that touches one of the upper frame Fa or vertical frames Db and Da, but that In this case, if the injection port Po side is tilted a little higher, the air in the upper part and the mortar M can be easily exchanged, and the possibility of forming a cavity near the upper frame Fa due to filling leakage can be prevented. After the injection described in 2. is completed, it is degassed and solidified in the same way as in the normal case, but at that time, the injected mortar M is mixed with the side templates Da and Db.

Or, since it was in contact with the flat surface of the intermediate template G coated with a mold release agent, the mortar M is solidified and taken out from the mold, and the side part that was in contact with the side templates Da, Db or the intermediate template G By making the required mortar flat surfaces of the openings Ta and Tb one surface of the panel, a beautiful finished mortar flat surface can be obtained, and the sandwiched space Q can be strictly formed by the prefabricated template A. A frame-equipped heat storage board B with a uniform thickness regulated by

(Laying of panels) (Part 1) A plurality of boards Ba with insulation material loading frames in which tubes P shown in cross section as shown in FIG. Joist 12. The engaging portions Ka and Kb of the rough floor 13 of the building are laid on the upper surface of the floor of the building consisting of the rough floor 13 by actual bonding, etc., and the board frame is laid as shown in Fig. 10. The connecting end Pa protruding from F is connected directly or through the U vent 15, and the pipe body P
The installation of the panel W is completed by forming a passage for hot water or cooling water and filling the gap V between the boards with mortar. (Part 2) A plurality of framed bows 1"Bb in which pipe bodies P are buried as shown in FIG.
1t14 and multiple framed bows 1”Bb on the L side.
Panels W are laid in the same manner as in the case of (Part 1) above, except that the panels W are laid all over.

(Effects of the Invention) (1) According to the vertical pouring method for constructing a heat storage board with a frame for a heating/cooling panel of the present invention, by using a prefabricated metal template,
The side templates Da, Db and the intermediate template G, which form a sandwiched space Q in which the thickness of the board is strictly regulated, and which abut against the sides OTa, Tb of the board frame F, are made of metal, etc. Since it is formed of a flat surface made of a plate, it has a uniform thickness and a high degree of flatness, and by using the intermediate shape material G, boats with excellent productivity can be obtained in multiple rows. That is, as in the past, when installing the board frame F, place the lower opening on the bottom board. Place the mortar in a thin layer, approximately 35cm thick of the board, through the wide-area upper opening, and flatten the wide-area L-side mortar surface by the self-smoothness of the mortar itself. Even if a self-leveling agent is used to form a surface, it is difficult to obtain an ideally flat surface, and there are slight differences in thickness between multiple bows 18. As a result, the quality of Board B is significantly improved compared to those that require adjustment during panel installation, and is not only homogeneous, but also not inferior in productivity. In addition, there is a lower template E that tilts the mortar injection port Pa side provided horizontally or at the top of the board frame F a little higher, and left and right side templates Da and Db.

Alternatively, the prefabricated formwork A, which combines it with the intermediate template G, does not take much time to assemble, can be formed with accurate dimensions, can be used extremely effectively by gillage, and has fluidity. There is also a greater degree of freedom in selecting mortar M than in the past. In addition, the board frame F is one end or central part of the upper frame Da or the vertical frame Db, Dc, which comes upward when carrying out the trailing manufacturing method.
Or, both of them are equipped with a mortar injection port Po, or the entire frame opening Ja is later installed as a mortar injection port Po, so that the side opening Ta becomes a flat surface of the floor when the panel is laid. There is no direct relationship with Tb, but it creeps into the last part of the injection or inside the upper layer, so the mortar injection port P
The presence of o does not have a negative effect on the function of the heat storage board B, and the injection operation and mortar material can be freely selected. (2) The assembly formwork of the present invention is composed of a plate body made of metal or the like, consisting of left and right side templates Da, Db, and an intermediate template G, and a profile with a U-shaped cross section or a square timber of wood. When manufacturing it, it is easy to control the dimensions accurately, and it is easy to handle when assembling and disassembling, and the use of a mold release agent makes it easy to peel off the hardened mortar surface and clean it for reuse. It doesn't take much time either. (3) Since the frame body J of the board frame F is made of a metal shape material, the frame can be constructed accurately and firmly, and the selection 1 positioning and processing of the frame of the mortar injection port Pa is easy; , the mortar injection port PO is separated from the side interlocks OTa, Tb that form a flat surface, and is at the highest position during injection, yet the injection surface of the mortar M is hidden within the frame, so a flat surface is formed. It will not have any negative impact on.
