Description

  The present invention relates to a formwork device for forming a reinforcing steel-containing concrete frame used in a house, a building having a height of about four floors, and the like, and a concrete frame construction method using the formwork device.

  Conventionally, in order to construct a building foundation or a concrete frame such as a concrete wall, it has been a principle to perform it at the construction site where it is constructed. In this construction, for example, after first excavating the ground and placing laying stones there, casting concrete material and constructing a root cutting part, a predetermined foundation for building a foundation or concrete wall on the root cutting part is constructed. Forms a formwork device of height. In this formwork device, two formwork bodies are set up with an arbitrary interval so as to oppose each other, and a vertical reinforcing bar, a horizontal reinforcing bar, etc. are arranged within the optional interval, and then a concrete material is poured into the formwork device. After the period has elapsed and solidified, the mold body is removed. Further, on this, a formwork device for constructing a concrete wall is formed and stacked up. The formwork device for constructing this concrete frame is provided with reinforcing bars in the gaps between the two formwork bodies, and between the two formwork bodies each provided with a through hole. It is provided to be opposed to each other, and a spacer member is attached to the through hole to support the formwork. In this formwork apparatus, a concrete material is poured between the formwork bodies and allowed to elapse for an appropriate period. After solidifying, a concrete wall is formed by removing the formwork body. As described above, in the conventional construction method, the respective operations such as placing a discarded concrete material, forming a form for constructing a concrete frame, and removing the form body after the concrete material is solidified are sequentially performed at the construction site.

  Conventionally, concrete frames such as concrete walls and concrete slabs are formed in block-shaped concrete walls and concrete slabs at factories, etc., and transported to the construction site for connection. There is something to arrange. Also in this case, the formwork device for forming the block-shaped concrete frame is provided with a reinforcing bar on the temporary table and a gap between two mold frames each having a through hole on the temporary table. Are provided so as to be opposed to each other, and a spacer member is attached to the through hole to support the mold body. A concrete material is poured between the mold bodies to allow a suitable period of time to elapse, and after solidifying, a block-shaped concrete casing is formed by removing the mold body.

  Furthermore, conventionally, there are some concrete frames such as concrete walls and concrete slabs that are formed with a heat insulating plate fitted therein. A formwork apparatus for constructing such a concrete frame is provided with a reinforcing bar in a portion that becomes a gap between two formwork bodies, and each of the two formwork bodies provided with through holes. A gap is provided between the two sheets in a state where a heat insulating plate is provided on at least one inner wall surface side, and is opposed to each other, and a spacer member is attached to the through hole to support the mold body. And this formwork apparatus poured concrete between mold bodies, allowed to elapse for an appropriate period, solidifies, and then removes the formwork body to remove the formwork body and insert a heat insulating plate into the concrete wall, concrete slab, etc. A concrete frame is formed.

A conventional formwork apparatus has first and second formwork that are vertically arranged facing each other at an arbitrary interval and in which mortar is placed inside, and these first and second formwork are horizontally arranged. Insertion groove holes penetrating in the direction are formed, and the first and second molds are vertically arranged facing each other, and are inserted into these insertion groove holes from the outer surface side, and are mutually connected on the inner side. The thing which has a connection member provided with the fitting part fitted in is proposed (for example, refer to patent documents 1).
According to this formwork apparatus, the formwork that can be separated from the connecting member and the formwork that can be separated are simply installed opposite to each other, and the connecting members provided inside the formwork are connected to each other. Therefore, it is possible to provide a formwork apparatus that does not require disassembly of the formwork.

In addition, the conventional heat-insulating panel for both formwork and the construction method using the same form a concave portion of a predetermined depth at a predetermined interval in a concave groove formed on one surface of the heat insulating plate, and on the bottom surface of the concave portion. It has been proposed that a through hole is formed on the other surface of the heat insulating plate, a protrusion is provided on the crosspiece, and the cast concrete material flows into the through hole and the recessed portion and hardens. (For example, refer to Patent Document 2).
According to this formwork apparatus, in a formwork combined heat insulation panel comprising a heat insulating plate and a crosspiece embedded in a concave groove formed on one surface thereof, between the placing concrete material and the heat insulating plate and the crosspiece. It is possible to provide a formwork apparatus that can ensure high unity and a construction method using the same.

Furthermore, a conventional heat insulating panel for both formwork and interior base and a method for constructing a reinforced concrete structure using the same are a heat insulating plate made of a synthetic resin foam, and a plurality of composite reinforcing materials arranged on one surface thereof. Proposed that the composite reinforcing material is fitted in the recessed groove of the heat insulating plate, and further provided with auxiliary heat insulating bodies having a thickness up to the surface of the composite reinforcing material on both sides of the composite reinforcing material (For example, see Patent Document 3).

However, the conventional formwork apparatus as described above and the concrete frame construction method using the same have the following problems.
(1) In any case, the conventional formwork apparatus needs to prepare a dedicated formwork body to be attached or detached, and requires a cost for forming this formwork body. In addition, the conventional formwork apparatus and the concrete frame construction method using the same are greatly affected by the weather when the concrete frame construction work itself is performed outdoors, and particularly when bad weather with strong wind and rain continues. The construction period may be extended and construction may not proceed. Further, in the case where the conventional concrete frame does not use a heat insulating plate, the produced concrete frame itself lacks heat insulation properties and has poor heat retention from the outside air. Furthermore, when the surface of the conventional concrete frame is exposed, the surface of the concrete is exposed to moisture and condensation, which contaminates the surface and has a cold appearance.

  (2) Since the formwork apparatus with the heat insulating plate is expensive in the formwork apparatus in a state in which the heat insulating plate is provided on the inner wall surface side of the conventional formwork body, a concrete case manufactured using these is provided. Buildings such as houses and buildings become expensive. In addition, it is difficult to firmly fix the outer wall plate to the heat insulating plate after removing the formwork, and a structure in which a space portion cannot be easily formed between the heat insulating plate and the outer wall plate. It has become.

  (3) The formwork apparatus disclosed in Japanese Patent Application Laid-Open No. 9-242231 is, for example, a concrete wall in which the first and second formwork itself is incorporated with a heat insulating plate made of foamed resin or the like, Alternatively, a concrete slab or the like can be formed, but a complicated structure for inserting and arranging the first and second molds facing each other is formed and attached to the insertion groove. There is a need for a connecting member that includes a fitting portion having a complicated structure for standing and holding. Therefore, in the above-mentioned formwork apparatus, the first and second formwork and the connecting member become expensive, and therefore the concrete frame produced using these becomes expensive, and as a result, such as a house or a building The building is expensive.

  (4) A heat insulating panel for a formwork disclosed in Japanese Patent Application Laid-Open No. 2002-201748 includes a heat insulating plate and a girder attached to the heat insulating plate, a concave groove in the heat insulating plate, and a recessed portion having a predetermined depth in the concave groove. In addition, it is necessary to form a through hole in the bottom surface of the recessed portion, and to provide a protrusion at a position facing the through hole provided in the heat insulating plate in the pier. Complex structural processing is required for boards and piers. Therefore, in the formwork apparatus, since the heat insulating plate and the pier are expensive, the concrete wall produced using these, or the concrete frame such as the concrete slab becomes expensive, and the building is expensive. It has become. Moreover, in the construction method using the above-mentioned formwork apparatus, since the viscosity of the cast concrete material is relatively high, it is difficult to harden the concrete material by filling it into the through holes and the recessed portions of the heat insulating plate. .

  (5) A method of constructing a reinforced concrete structure using a formwork / interior base combined heat insulating panel disclosed in Japanese Patent Application Laid-Open No. 2009-221821 and forming a concave groove in a heat insulating plate, and providing a composite reinforcing material there In addition to being fitted, auxiliary heat insulators are provided on both sides of the composite reinforcing material. However, it is not easy to form these structures on the heat insulating plate, and the heat insulating panel for both the formwork and the interior base is expensive. Moreover, in the construction method of the reinforced concrete structure using the heat insulating panel for both the formwork and the interior base, even if the composite reinforcing material is held by a locking member such as a screw or a nail through the heat insulating plate, the heat insulating plate is synthesized. Since the resin foam cannot be firmly held, the interior board to be fixed to the composite reinforcing material cannot be firmly fixed.

  The present invention has been made in view of such circumstances, and is a formwork for forming a concrete frame that is excellent in heat retention and does not require a dedicated formwork to be attached or detached and can be easily and inexpensively.

(A), (B) is a partial plan view of a formwork apparatus according to an embodiment of the present invention, a formwork apparatus of a modified example, a formwork apparatus of another modified example, and a longitudinal sectional view taken along line AA ′. It is. It is explanatory drawing of the horizontal member of the same formwork apparatus. It is explanatory drawing by which a collar member is attached to the horizontal member of the same formwork apparatus. (A), (B) is explanatory drawing of the construction method of the concrete frame using the same formwork apparatus, respectively.

Then, the form for implementing the formwork apparatus of this invention is demonstrated.
As shown in FIGS. 1 (A) and 1 (B), a formwork apparatus 10 according to an embodiment of the present invention includes a reinforced concrete wall such as a normal house or a relatively low building of about 4 stories, or reinforced concrete. It is used to form a concrete frame 20 (see FIG. 4B) such as a slab. This concrete frame has a form having plate-like heat insulating plates 11 made of synthetic resin foam on both surfaces of a concrete material 21 (see FIG. 4B) in which reinforcing bars are embedded. The heat insulating plate 11 is used as a formwork material for pouring the concrete material 21 at the time of construction, and is used as it is as a heat insulating material after the concrete material 21 is poured and solidified. In addition, the material of the heat insulating plate 11 is not particularly limited, but a hard polyurethane foam, a flexible polyurethane foam, a polyethylene foam, a polystyrene foam, a polypropylene foam, a phenol foam, a rigid vinyl chloride foam, a urea foam, an acrylic foam, Cellulose acetate foam or the like can be used. The thickness of the heat insulating plate 11 is not particularly limited, but if it is about 50 to 70 mm, it can withstand sufficient heat retention and pressure when the concrete material 21 is poured. The heat insulating plate 11 formed in this way can be used widely and generally on the market, and the surface is a square or rectangular plate that is not subjected to any special processing such as concave grooves or through holes on the surface. Therefore, the cost of the mold apparatus 10 can be prevented from being increased.

  The mold apparatus 10 includes a first mold body 13 having a plate-like heat insulating plate 11 made of a synthetic resin foam and a transverse member 12 made of a long H-shaped material extending in the lateral direction, It has the 2nd formwork 13a. The first and second mold bodies 13 and 13a can be connected to the H-shaped groove of the horizontal member 12 at the upper and lower ends of the plate-like heat insulating plate 11, and a plurality of sheets can be connected in the vertical direction. And are arranged upright in a state where they are opposed to each other at an arbitrary interval. The first and second mold bodies 13 and 13a are opposed to each other such that the height positions of the respective lateral members 12 are substantially the same position.

  In addition, the mold apparatus 10 described above is provided with an arbitrary interval on the outside of each of the first and second mold bodies 13 and 13a standing opposite to each other, and the heat insulating plate 11 and the lateral member 12 are respectively provided. It has the vertical member 14 which consists of the rod which is made to stand so that it may contact | abut and is fixed to the horizontal member 12 and arrange | positioned in parallel. Although the shape of the vertical member 14 is not particularly limited, an interior plate, an exterior plate, etc., which will be described later, are attached to the vertical member 14, so that the cross section is a quadrangle, the inside is a hollow quadrangle, It is preferable that it is a rod body made of the same H-shaped material as the member 12 or a U-shape.

  As shown in FIG. 2, the horizontal members 12 of the first and second mold bodies 13 and 13a are different in the heights a, b, c, and d from which the H-shaped material protrudes in the H-shaped groove direction. Is preferred. When the concrete material 21 is poured into the gap between the first and second mold bodies 13 and 13a, pressure is applied to the mold apparatus 10 from the inside to the outside. Further, in the formwork device 10, the vertical member 14 comes into contact with a portion of the horizontal member 12 that is outside the H-shaped material. Therefore, the heights a, b, c, and d of the H-shaped material of the transverse member 12 support the heat insulating plate 11, and the heights a and b of the outer portions for contacting the vertical member 14 are the inside. It is preferable to be higher than the heights c and d. Further, when the heat insulating plate 11 is mounted, the upper end portion of the first and second mold bodies 13 and 13a is inserted into the H-shaped groove on the lower side of the upper lateral member 12 to be fitted. After that, the lower end portion can be mounted by being dropped into the H-shaped groove on the upper side of the lower lateral member 12. Therefore, the heights c and d of the inner part of the H-shaped material of the horizontal member 12 are the heights of the upper part of the inner part and the height d of the lower part of the inner part in order to fit the heat insulating plate 11. It is preferable that the height be higher than c. Further, the horizontal member 12 makes it easier to drop the heat insulating plate 11 into the upper H-shaped groove, and the height c of this portion is attached to the upper side of the portion where the flange member 15 described later is inside the H-shaped material. Is preferably the lowest. That is, it is preferable that the heights a, b, c, and d from which the H-shaped material of the transverse member 12 protrudes are b> a ≧ d> c.

  Furthermore, the above-mentioned formwork apparatus 10 includes a plurality of U-shaped metal rods that are hooked on the respective transverse members 12 of the first and second formwork bodies 13 and 13a facing each other. Each has a gutter member 15 which is attached with an arbitrary interval between adjacent ones. This saddle member 15 is formed by bending a metal bar made of a steel bar such as round steel, square steel, flat steel or the like into a U-shape, and the first and second formwork even when the concrete material 21 is poured. The bodies 13 and 13a can be sufficiently supported. Moreover, since this collar member 15 is widely commercially available and is very inexpensive, it is possible to prevent the cost of the mold apparatus 10 from being increased. The length of the straight line portion until the collar member 15 is folded into a U-shape is substantially the gap distance between the first and second mold bodies 13 and 13a. Although this gap interval differs depending on the structure of the concrete frame 20 such as a reinforced concrete wall or a reinforced concrete slab, there is no problem in terms of strength if it is about 170 to 200 mm in a normal house or a building of up to about 4 stories. There is no. Therefore, it is preferable that the length of the straight portion of the flange member 15 is about 170 to 200 mm.

  In a formwork apparatus 10a as a modification of the formwork apparatus 10 described above, the transverse member 12 is preferably made of metal or hard resin. The material of the metal or hard resin is not particularly limited, but in the case of metal, for example, iron, copper, stainless steel, aluminum, etc. can be used, and in the case of hard resin, for example, hard chloride Vinyl resin, ABS resin, or the like can be used. When the horizontal member 12 is made of metal, for example, the metal plate is bent in a U shape, and the groove bottoms are joined to each other, or are fixed to the vertical member 14 with the groove bottoms in contact with each other. It can be easily formed into an H-shaped material. Moreover, when the horizontal member 12 consists of hard resin, an H-type material can be easily formed by pressing molten resin. In any case, since the structure is simple and easy to form, the cost can be reduced.

  And as shown in FIG. 3, said formwork apparatus 10a is good to have the through-hole 16 in the site | part to which the collar member 15 of the groove bottom part edge part of the horizontal member 12 is attached. In this through hole 16, the flange member 15 can be easily positioned and attached, and the opposed lateral member 12 is securely held between the first and second mold bodies 13, 13 a. When concrete material 21 is poured into the gap, it can support that pressure is applied from the inside to the outside. Moreover, even if the concrete material 21 is poured by fitting the collar member 15 in the through-hole 16, it can prevent the horizontal member 15 from falling off.

  In the formwork apparatus 10b of another modification of the formwork apparatuses 10 and 10a, the vertical member 14 is preferably made of wood or hard resin. The materials of wood and hard resin are not particularly limited, but in the case of wood, all kinds of materials are not required, and composite materials such as waste wood and glass fiber are molded. Those with enhanced rigidity can also be used. When the vertical member 14 is a hard resin, the same hard vinyl chloride resin, ABS resin, or the like as the hard resin used for the horizontal member 12 can be used. In addition, although the magnitude | size is not specifically limited, the vertical member 14 is a pressure applied from the inside to the outside even when the concrete material 21 is sufficiently poured, as long as the outer shape is about 40 to 50 mm in a sectional view. Can support. Further, the shape of the vertical member 14 in a cross-sectional view may be a square shape, a square shape having a hollow inside, an H-shape, a U-shape, or the like. It is preferable that the contact surface and the surface opposite to the contact surface have a shape that has a parallel surface.

  And the said formwork apparatus 10b is good to have the securing member 17 which penetrates the vertical member 14 and adheres to the horizontal member 14. The locking member 17 can be a screw nail, a nail, a bolt, a nut, or the like. The screw nail is screwed in from the vertical member 14 side, the nail is driven, or the vertical member 14 and the horizontal member 12 are attached. The vertical member 14 can be easily fixed to the horizontal member 12 by opening an insertion hole for attachment and tightening it with a nut through a bolt.

Next, a concrete frame construction method using the above-described formwork apparatuses 10, 10a, and 10b will be described with reference to FIGS. 4 (A) and 4 (B).
As shown in FIG. 4A, there is a construction method of the concrete frame 20 using the above-described formwork apparatuses 10, 10a, 10b, which is constructed entirely at the construction site. In this case, first, after excavating the ground, placing laying stones there, pouring a discarded concrete material to construct a root cutting part, a formwork device for a foundation is formed on the root cutting part. And, on the root cutting part, the two formwork bodies of the foundation formwork apparatus are set up with an arbitrary interval so as to oppose each other, and a vertical reinforcing bar, a horizontal reinforcing bar, etc. are arranged within the optional interval. After that, the foundation is constructed by pouring the concrete material for foundation, solidifying it after an appropriate period of time, and then removing the formwork. Furthermore, on the foundation, reinforcing bars are arranged at an arbitrary interval between the first and second formwork bodies 13 and 13a of the above-described formwork apparatuses 10, 10a and 10b, and the heat insulating plate 11 and the sideways. After the first and second mold bodies 13 and 13a composed of the member 15 and the vertical member 14 are set up to face each other with an arbitrary interval while fitting the flange member 15, the first and second mold bodies 13 and 13a Concrete material 21 is poured and cured after an appropriate period of time. In addition, after hardening the concrete material 21, when forming the concrete frame 20 further upwards, it can form by repeating performing said construction method after hardening.

  Alternatively, a method for constructing the concrete frame 20 includes, for example, manufacturing the block-shaped concrete frame 20 in a factory or the like and transporting the block to the construction site for connection. Also in this case, on the temporary table, reinforcing bars are disposed at portions at arbitrary intervals between the first and second mold bodies 13 and 13a of the mold apparatuses 10, 10a and 10b, and heat insulation is performed. After the first and second mold bodies 13 and 13a composed of the plate 11, the lateral member 15, and the vertical member 14 are set up to face each other with an arbitrary interval while the flange member 15 is fitted, the arbitrary interval is set. The concrete material 21 is poured into the portion to be and cured after an appropriate period of time.

  Next, as shown in FIG. 4 (B), the construction method of the concrete casing 20 using the above-mentioned formwork devices 10, 10a, 10b is the interior wall plate, floor board, ceiling on the vertical member 14 on the house side. The outer wall plate 22 on the outdoor side of the exterior wall plate is attached to the outer wall plate 22 on the indoor side of the plate and the vertical member 14 on the outdoor side of the plate to form a space 23 between the outer wall plate 22 and the heat insulating plate 11. Since the vertical member 14 is firmly fixed to the horizontal member 12 by the locking member 17, the outer wall plate 22 such as the interior, exterior wall surface plate, floor plate, or ceiling plate can be firmly held. The space 23 between the outer wall plate 22 and the heat insulating plate 11 can dry the moisture on the concrete surface and the moisture between the concrete surface and the heat insulating plate due to condensation, and prevent the surface of the concrete material 21 from being exposed. This can prevent the cold feeling.

  In addition, the interior wall plate of the concrete frame 20 and the outer wall plate 22 of the exterior wall plate are not particularly limited in material and design, and various types are already commercially available. Any one can be selected according to the cost and can be adopted as an inexpensive one. In addition, when the concrete frame 20 such as a concrete slab does not require one or both of the floor board and the ceiling board, after removing the unnecessary vertical members 14, the surface of the concrete material 21 is removed. The surface of the concrete material 21 can be used as it is exposed or after being coated with finishing concrete or mortar.

  The formwork apparatus of the present invention and the method of constructing a concrete frame using the same are warm in winter and require little heating costs, cool in summer and almost no cooling costs, and an inexpensive and highly durable house Or it can be provided as a building.
