[0002]

2. Description of the Related Art Conventionally, a building having a concrete structure is excellent in wind resistance, fire resistance, earthquake resistance, and the like, and is therefore constructed as a high-rise building, but requires a large amount of expense to construct. . Therefore, as a house for the common people, a wooden house with low construction cost was constructed, and it was generally avoided to construct a house with a concrete structure. But,
In recent years, housing space with high airtightness and heat insulation has been generally desired as housing equipment, and in general houses, concrete-structured houses that are functionally superior to wooden houses have been constructed. It is getting. In this concrete-structured house, when an outer wall or a partition wall is constructed of a concrete wall, as shown in FIG. 18, a plywood form or a metal form is installed oppositely, and the separator is passed through the opposed form. Piercing or hitting the protruding end of the separator on a pier provided on the outer surface of the formwork, locking the separator with a nut or a wedge or the like to hold the formwork at a predetermined interval, and then laying concrete inside. Is filling. Furthermore, after the concrete filled inside is solidified, the formwork is removed from the concrete surface, the projecting end of the separator is cut off, and the formwork is usually used again while removing, cleaning and storing the adhered concrete and the like. is there.

[0003]

However, in order to maintain the strength of the formwork, the work of assembling the formwork by penetrating a large number of separators into the opposed formwork requires a lot of trouble, and the inside is filled. After the cured concrete is cured,

[0015]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention has first and second molds which are vertically arranged face to face at an arbitrary interval and have mortar cast therein on the inner side. These first and second molds are provided. Is formed with an insertion slot that penetrates in the lateral direction.
It has a connecting member provided with a fitting portion that is inserted into each of these insertion slots from the outer surface in a state where the second formwork is vertically arranged to face each other, and is fitted to each other on the inner side. It is a formwork device. A plurality of first and second connections are provided on the inner side of the first and second forms in a state where the connecting members are inserted from the back sides of the first and second forms and the first and second forms are vertically arranged to face each other. A plurality of fitting portions of the member are fitted to each other to connect them firmly and securely, thereby ensuring the strength of the assembled formwork. Further, the first and second forms can be buried and solidified in a mortar or a concrete filled therein, so that the work time for constructing and constructing the concrete wall and the construction cost can be reduced. In addition, since the fitting part connected by the connecting member is strong, it has extremely large strength against the force applied by mortar and concrete at the time of construction and the external shock due to the earthquake etc. after construction. Can be secured. In particular,
In the construction method of the formwork apparatus, in a state where the first and second members are opposed to each other with a space therebetween and vertically arranged, a connecting member is inserted from the back side and the first and second connecting members inside the formwork are inserted. It is merely fitted by the fitting part of. Therefore, an operator can construct a strong form very easily without requiring special tools and without requiring skilled skills.
Also, since the formwork and the connecting member can be separated, there is no need to perform packing so that the connecting member protruding from the formwork does not damage other formwork, connecting members, etc. even during their transportation, which is a great deal. Expenses can be reduced. In addition, the specific shape and configuration of the connecting member may be set arbitrarily, and may be any configuration provided that a fitting portion is provided on the distal end side.
The shape of the insertion slot may be arbitrarily determined, but it is preferable to adopt a configuration in which the connecting member is inserted as closely as possible so as to maintain the strength of the mold frame. The connecting member may be configured as an integral or separate body. The material of the mold itself is not limited, and it may be made of light alloy, synthetic resin, wood, paper, metal, alloy or any other material.

Further, the connecting member has a backrest portion which presses against an outer surface of one of the first and second molds when inserted into the insertion slot. When the connecting member is inserted into the insertion slot from the outer surface of one of the first and second molds, a backrest provided on the connecting member is provided on the outer surface of the mold. The contact depth defines the insertion depth of the connecting member into the mold. As a result, the installer does not need any special technique, and can easily perform the installation of the formwork apparatus. Also, after a wall or the like is constructed using this formwork device, when a force is applied to the connecting member inside the wall from the wall by a load from the outside, the load is applied from the backrest portion of the connecting member abutting on the outer surface side of the formwork. Since it can be dispersed toward the mold, the connection member is prevented from being broken, and the strength of the wall is increased. The backrest may be an L-shaped abutment on the outer surface side of the formwork, and various decorative patterns may be applied to the outer surface side, grooves may be formed, and the outer surface may be swollen to obtain another shape. A pattern may be formed, or a configuration in which the pattern is not simply formed into a flat shape may be adopted.

Further, the connecting member is detachably inserted into the insertion slots of the first and second forms, so that the form and the connecting member are separately transported to the construction site. ,
The assembly of the device can be completed simply by assembling it at the time of construction. Therefore, since the mold section and the connecting member can be manufactured separately, manufacturing errors of the mold apparatus itself can be reduced, leading to a reduction in manufacturing cost. Further, since the connecting member can be inserted into and detached from the mold frame by hand without using a special tool or the like, it can be easily performed even by a skilled worker.

Further, since the connecting member is formed in a substantially T-shape in a front view, the connecting member is inserted from the outer surfaces of the first and second molds, and the connecting members projecting from the respective molds are fitted. When fitted, the fitted portion is substantially straight and has the strongest shape. Therefore, when the formwork device of the present invention is constructed, or when a strong impact such as an earthquake is applied to the formwork device, the force applied to the connecting member is dispersed and relieved, and the connection member is strongly fitted. By doing so, the strength of the formwork device is ensured.

Further, since a plurality of the insertion slots provided in the formwork are provided in the same formwork and a plurality of connecting members can be detached, the mortar and concrete at the time of construction work. The force applied to each connecting member and the sudden impact applied to the applied force and the impact applied by the external earthquake after the construction of the formwork are distributed to each connecting member inserted into the formwork and the formwork and Protecting walls from destruction. The number of specific slots may be arbitrarily set, but it is more preferable to provide a large number of slots because a large number of connecting members can be connected.

The plurality of connecting members inserted into the insertion slots of the formwork are integrally connected on the outer surface side, so that the plurality of connecting members are integrally connected on the outer surface side. A kind of rigid body can be formed, and a large pressure resistance load can be secured by connecting the left and right connecting members. In addition, since the connecting member can be inserted into the form at one time at the time of construction of the form device, the work of inserting the connecting member into the form can be omitted, so that the work of constructing the form device can be performed efficiently. .

Further, since the insertion slot provided in the mold is composed of a straight slot and a rectangular slot, the cut-out portion for the insertion slot can be minimized. And the effect on appearance is small.
Further, the waste of material due to the notch when forming the insertion slot of the mold can be minimized, so that the waste of material cost can be minimized. In addition, the strength of the formwork device is secured by dispersing the force received by the connecting member when the connecting member receives an impact or the like after the construction of the formwork or after the construction, so as to reduce the impact by making the groove softer. It is possible.

Further, the insertion slot provided in the mold has a cross section substantially the same shape as the T-shape of the connection member, so that when the connection member is inserted into the mold, the connection member is formed. Is not displaced inside the insertion slot, so the notch for the insertion slot is minimized to maintain the strength of the formwork itself, and to prevent impact from outside during and after the construction of the formwork On the other hand, considerable strength can be maintained. Further, the construction worker can efficiently and easily carry out the construction of the formwork apparatus by hand without needing tools or the like simply by inserting the connecting member into the formwork.

Further, since the mold is made of a heat-insulating material such as foamed resin, it is possible to remove the same mold as it is after casting the mortar or concrete after the mold has been applied and solidified. Since it can be used as a heat insulator without the need for a separate heat insulator, material costs can be saved. In addition, the cost of the material itself, such as foamed resin, is inexpensive, and since it is excellent in machinability, manufacture is extremely simple. Further, since the foamed resin or the like is lightweight, it can be easily transported and the transportation cost can be reduced.

Further, since the mold is reinforced by a reinforcing member integrally embedded in the same mold, the strength of the mold itself can be formed to be strong and combined with the connecting force of the connecting member. The strength of the entire frame device can be greatly improved. Further, since the material for manufacturing the strong mold itself can be saved, the manufacturing cost can be reduced. Further, the thickness of the formwork can be reduced, the weight can be reduced, the transportation cost can be reduced, and the construction work can be easily performed. Further, since the reinforcing member is integrally formed, it is difficult to separate from the formwork, and has an effect that the strength is extremely high with respect to a strong impact such as an earthquake or the weight of the building itself.

The ridges 36 provided at the upper end of the formwork 12 on the lower side of the formwork device 10 connected in this manner and the concave grooves 37 provided at the lower end of the formwork 12 fit together, and also in the horizontal direction. As a result, the side ridges 38 and the side concave grooves 40 are connected and fitted to each other, so that the watertightness of the formwork devices 10 is maintained, and even if a liquid liquid solidifying material such as concrete is poured, leakage is prevented. ing.

3 to 5, an insertion slot 14 is provided in the first and second mold frames 12a and 12b so that a connecting member 16 described later penetrates in the lateral direction. These insertion slots 14 are formed so as to penetrate the outer and inner surfaces of the first and second mold frames 12a and 12b. As shown in FIG. 4, a plurality of these insertion slots 14 are formed in parallel in the vertical direction when viewed from the outer surface side of the mold. A plurality of connecting members 16 can be attached to and detached from the insertion slots 14. Only one insertion slot 14 may be provided so that one connection member 16 is inserted and connected.

The insertion slot 14 is formed on the outer surface side of the mold body 12 at a substantially central position of the upper and lower heights of the molds 12a and 12b. It comprises a linear slot 32 continuously extending vertically and having a width smaller than that of the rectangular slot 34. The end side of the linear slot 32 is set to have a length from the upper and lower sides of the mold to a portion that is slightly spaced.

As shown in FIG. 3, the insertion slot 14 has a substantially isosceles triangular base 33 with a mountain-like peak facing the opposite side of both molds when viewed in a vertical cross section. To

[0061]

As described above, according to the formwork device of the present invention, the mold devices are vertically arranged facing each other at arbitrary intervals.
There are first and second molds on which mortar and the like are cast on the inner side, and these first and second molds are formed with insertion slots that penetrate in the lateral direction. It has a connecting member provided with a fitting portion that is inserted into each of these insertion slots from the outer surface in a state where the second formwork is vertically arranged to face each other, and is fitted to each other on the inner side. As a result, the first and second molds arranged to face each other are firmly and reliably connected by fitting the plurality of fitting portions of the plurality of first and second connecting members provided on the inner surface side thereof, The strength of the assembled form can be maintained. In addition, since the first and second forms are buried and solidified in the concrete filled therein and can be used as a heat insulating material for a concrete wall or an exterior material, there is no need to dismantle the form.
Reduction of working time in construction of concrete wall,
The construction cost can be reduced. Further, once the first and second connecting members are fitted, they do not come off, so that the connecting operation of these first and second connecting members can be performed continuously, and the construction time is greatly reduced and the construction work is simplified. Can be secured. Furthermore, since the waiting period for curing and the formwork dismantling work are not required, the construction period can be greatly reduced, and work and labor costs can be saved. Furthermore, by separating the first and second molds and the connecting member also during transportation, the connecting members protruding from the respective molds can prevent damage during transportation and other handling, and can also prevent damage during transportation. In addition, since the packing for preventing the above-mentioned problems can be saved and the volume of the transportation becomes small, the transportation can be carried out in large quantities at one time, and the cost of transporting the formwork apparatus can be greatly reduced. Also, since the first and second molds and the connecting member can be detached and attached, the first and second molds and the connecting member can be manufactured separately, so that they can be manufactured by a relatively simple manufacturing process. It can be manufactured inexpensively and efficiently without requiring special techniques.

Further, the connecting member has a backrest portion which presses against the outer surface of one of the first and second molds when inserted into the insertion slot. With this configuration, when the connecting member is inserted into the insertion slot from the outer surface side of one of the first and second forms, the backrest provided on the connecting member on the outer surface of the form is provided. Since the parts abut against each other in a pressing manner, the insertion depth of the connecting member to the formwork is defined. As a result, the work of inserting the connecting member to this formwork can be performed in a short time, easily, and excessively inserted. Therefore, it is possible to prevent the operator from making mistakes during the construction work, such as detachment from the formwork, and to easily and efficiently perform the construction work of the formwork even if he is not a skilled worker. Further, the first and second molds are vertically arranged facing each other at an arbitrary interval, and a connecting member inserted into the insertion slot from their outer surfaces is fitted inside to form a mortar or the like. When driven into the inside of the frame, the mortar or the like receives a force applied to the connecting member in the entire vertical direction on the outer surface side of the form, so that a large strength can be maintained.

The connecting member is removably inserted into the insertion slots of the first and second forms, so that the form and the connecting member can be separately transported to the construction site. ,
Since the assembly of the equipment can be completed simply by assembling at the time of construction, it is possible to reduce the volume when transporting the construction material, secure the simplicity of storage and handling, and prevent the damage of the formwork while at the same time forming the formwork It is possible to effectively reduce the manufacturing cost on the premise of manufacturing a separate body from the connecting member.
Accordingly, no special technique is required, and the number of manufacturing errors of the formwork apparatus itself is extremely small, so that the apparatus can be manufactured inexpensively and efficiently.

The connecting member is formed in a substantially T-shape when viewed from the front, so that when the formwork device of the present invention is constructed or when a strong impact such as an earthquake is applied to the formwork device, By dispersing and relieving the force applied to the connecting member, breakage of the formwork device is less likely to occur. Therefore, the material for manufacturing the formwork device itself can be selected from materials that are lightweight and easy to form, so that the material can be easily transported and easily constructed.

Further, a plurality of the insertion slots provided in the mold are provided in the same mold, and a plurality of connecting members are detachable, so that the first and second molds face each other. When the mortar, concrete, etc. are poured into these insertion slots from the outer surface in the state where they are vertically arranged, and they are fitted together on the inner side, a greater strength is applied to them when they are poured. Can be kept. In addition, the work of the formwork device can be easily performed, and the work can be easily performed even by a non-skilled worker, and the work of the formwork device can be efficiently performed in a short time.

The plurality of connecting members inserted into the insertion slots of the formwork are integrally connected on the outer surface side, so that a kind of rigid body is formed by integrally connecting the plurality of connecting members. It is possible to secure a large pressure resistance load by connecting the left and right connecting members. Therefore, it is possible to maintain extremely high strength even when constructing the formwork devices and against impacts such as earthquakes after constructing them.

Further, since the insertion slot provided in the mold is composed of a straight slot and a rectangular slot, the cut-out portion for the insertion slot can be minimized. And has little effect on appearance. In addition, the strength of the formwork device is secured by dispersing the force received by the connecting member when the connecting member receives an impact or the like after the construction of the formwork or after the construction, so as to reduce the impact by making the groove softer. It is possible.

The insertion slot formed in the mold has a substantially same cross section as the T-shape of the connection member, so that the insertion member can be inserted into the mold when the connection member is inserted into the mold. Since the member does not shift inside the insertion slot of the formwork, the strength of the cutout for the insertion slot is minimized while maintaining the strength. It can maintain considerable strength against In addition, the construction worker can efficiently and easily perform the construction of the formwork apparatus by hand only without inserting tools or the like simply by inserting the connecting member into the formwork.

Since the mold is made of a heat insulating material such as a foamed resin, it is possible to remove the same mold as it is after the mortar or concrete has been poured into the mold and then solidified. Since it can be used as a heat insulator without the need for a separate heat insulator, material costs can be saved. In addition, the cost of the material itself such as a foamed resin is low, and the production is extremely simple because of excellent machinability.

Further, since the mold is reinforced by a reinforcing member integrally embedded in the same mold, the strength of the mold itself can be formed to be strong and combined with the connecting force of the connecting member. The strength of the entire frame device can be greatly improved. Further, since the material for manufacturing the strong mold itself can be saved, the manufacturing cost can be reduced. Also, the weight of the formwork can be reduced, the transportation cost can be reduced, and the construction work can be performed easily. Also,
Since the reinforcing member is integrally formed, the reinforcing member is not easily separated from the mold, and has an effect that the strength is extremely high with respect to a strong impact such as an earthquake or the weight of the building itself.
