Definitions
- the present invention relates to a fixed-type form panel system comprising form panels constituting a foundation wall, a bottom between floors, and a roof of a building or a concrete structure, compression cement boards using vertical reinforcement-purpose metal plate studs, and steel studs.
- FIG. 1 is a perspective view illustrating the structure of a concrete frame constructed by means of a conventional form system using plywood forms and reinforcing bars.
- reinforcing bars 1 and 2 are disposed vertically and horizontally on the basis of the thickness and height of a wall body designed to construct a foundation wall or a wall
- reinforcing bars 3 which are bent in multi-cornered shapes or circular shapes, are disposed around the reinforcing bars 1 and 2
- the reinforcing bars 3 are connected to the reinforcing bars 1 and 2 by means of wires so as to construct the conventional concrete structure for building or civil-engineering works.
- forms 4 and 5 which are made of wood or steel, are disposed while being opposite to each other along the arranged reinforcing bar frame, and connecting pins are fixedly inserted through connection holes 6 formed at the forms 4 and 4 to connect the forms 4 and 5 to each other.
- the frame of the forms is prepared.
- Concrete 7 is injected into the reinforcing bar and form frames. The concrete is cured and dried for approximately 3 to 7 days. After the concrete 7 is solidified, the forms 4 and 5 are disassembled. Finally, supporting pins protruded from the surface of the concrete or protruded concrete parts on the surface of the concrete are appropriately eliminated.
- the above-described conventional form system has been widely used to construct the retaining wall-type reinforced concrete frame.
- the conventional retaining wall-type reinforced concrete frame system requires a large number of wood or steel forms.
- a large amount of subsidiary materials, including supporting members, are required to connect the forms to each other and construct the frame, which increases labor and time.
- a large number of reinforcing bars are vertically disposed, and other reinforcing bars are bent and curved such that the bent and curved reinforcing bars intersect with the vertically disposed reinforcing bars.
- the reinforcing bars, which intersect each other are connected to each other by means of wires. In this way, the frame is prepared. This requires a large amount of materials. After the concrete is dried, the forms are disassembled, and then removed, which requires labor and time.
- FIG. 2 is a perspective view illustrating the structure of a foamed polystyrene hollow block manufactured by means of a conventional foam forming machine. As illustrated in FIG.
- the foamed polystyrene hollow block manufactured by means of the conventional foam forming machine comprises: foamed polystyrene block parts 8 having protrusions formed at the upper ends thereof; and block supporting pins 11 disposed in the foamed polystyrene block parts 8 or between the foamed polystyrene block parts 8.
- the block supporting pins 11 are made of metal materials.
- the foamed polystyrene hollow block is manufactured as follows: the metal block supporting pins 11 are disposed in a mold, and foamed polystyrene, which is light in weight and has excellent heat insulating effects, is injected into the mold by means of the foam forming machine.
- the foamed polystyrene hollow block is separated from the mold, cooled, and then dried. Since the foamed polystyrene hollow block is manufactured using the mold, however, the shape and the structure of the foamed polystyrene hollow block are limited such that the foamed polystyrene hollow block is easily separated from the mold. Also, the size of the mold is increased as the size of the foamed polystyrene hollow block is increased, which is not economical. Furthermore, the foam forming machine, which is very expensive, is required, and it is required to manufacture a large number of molds corresponding to different sizes and shapes of the foamed polystyrene hollow block.
- the foamed polystyrene hollow blocks When concrete is injected into the foamed polystyrene hollow blocks, the foamed polystyrene hollow blocks may collapse or concrete may leak from the connections between the foamed polystyrene hollow blocks, due to the weight and pressure caused by the injected concrete. For this reason, it is required that a bonding agent be applied to the connections between the foamed polystyrene hollow blocks, which are arranged not only above and below but also right and left. This is very troublesome work. After the concrete filled in the foamed polystyrene hollow blocks is solidified, the foamed polystyrene material parts are exposed from the outer surface of the structure.
- the foamed polystyrene material parts have poor thermal resistance, and therefore, they may be easily burnt when a fire breaks out. For this reason, it is required that cement be applied to the entire surfaces of the structure before various interior and exterior decoration materials, such as paint, wall paper or timber, tile, marble, etc., are attached to the insides and outsides of the hollow blocks. However, the cement is not easily attached to the foamed polystyrene material parts. Consequently, it is further required that additional glass fiber nets or wire nets be attached to the foamed polystyrene material parts, and then the cement, for example, mortar, be thickly applied to the foamed polystyrene material parts with the glass fiber nets or wire nets attached thereto.
- cement for example, mortar
- FIG. 45 is a view illustrating a conventional retaining wall-type reinforced concrete frame system used to construct a bottom between floors. In the conventional retaining wall-type reinforced concrete frame system used to construct a bottom between floors as illustrated in FIG.
- wood plate or iron plate forms 4 are horizontally disposed between a wall 13 and another wall 14 such that the wood plate or iron plate forms 4 are used as supporting plates 12 in which concrete is filled, and reinforcing bars 1, which are stacked at the upper part of the retaining wall-type reinforced concrete frame system, side forms 5 that support the concrete, and the supporting plates 12 are supported by means of a plurality of steel pipes 15 disposed between the supporting plates 12 and the bottom of the downstairs.
- the steel pipes 15 are vertically mounted on the bottom of the downstairs such that the forms serving as the supporting plates 12, which are made of wood, for example, plywood, are supported by means of the steel pipes 15 in order to reduce load applied to the supporting plates 12.
- connection system has been proposed wherein pipes are fixed between form panels for convenience in piping works.
- all the pipes are mounted before concrete is injected.
- the pipes are integrally connected to the concrete, and therefore, the pipes cannot be replaced after all the pipes are mounted.
- the present invention has been made in view of the above problems, and it is an object of the present invention to provide a fixed-type form panel system comprising compression cement boards, foamed plastic panels, which serve as not only heat insulating members but also interior and exterior decoration members while being easily mounted, and steel studs, wherein each of the compression cement boards use metal plate studs as vertical or horizontal reinforcing members instead of vertically or horizontally disposed reinforcing bars, or the compression cement boards are reinforced with cement board reinforcing members.
- a form panel system comprising: compression cement boards disposed opposite to each other while being spaced a predetermined distance from each other, the compression cement boards being reinforced with fiber materials; reinforcing boards obtained by forming the compression cement boards in predetermined shapes, or foamed plastic heat insulating panels; and metal plate studs disposed between the compression cement boards, the metal plate studs being composed of metal plates having predetermined thicknesses and distances therebetween, which are selected depending on the durability of concrete, each of the metal plate studs having at least one opening formed therein, each of the metal plate studs being provided at both opposite side ends thereof with bent parts, wherein the metal plate stud is fixed to the respective compression cement boards by means of fixing pieces, and concrete is injected and cured into the space between the compression cement boards, to which the metal plate studs are fixed and the foamed plastic heat insulating panels are attached, whereby the fiber-reinforced compression cement boards, the foamed
- an integrated fixed-type form panel system comprising fiber- reinforced compression cement boards, foamed plastic heat insulating panels, metal plate studs having openings formed therein according to the present invention
- reinforcing bars, plywood, and materials for metal plate forms which are mainly used to construct a wall of a building or a concrete structure for civil- engineering works in a retaining wall-type reinforced concrete frame system are reduced, a reinforcing bar bending process and a connecting process of connecting the reinforcing bars to each other by means of wires are eliminated, and a form frame preparing process is simplified.
- the compression cement boards used for the panel system according to the present invention are compressed by means of rollers with the result that the surfaces of the compression cement boards are smooth. Consequently, an interior and exterior decoration process is simplified when the compression cement boards according to the present invention are used.
- the compression cement boards are used for a form in which concrete is injected and cured, and the form including compression cement boards are not disassembled after the injected concrete has been solidified.
- the strength of the concrete is increased by means of the compression cement boards, and therefore, the amount of concrete to be injected is reduced.
- concrete is cured for approximately 3 to 7 days after the concrete is injected into the form, and then the form is disassembled.
- moisture is rapidly evaporated from the concrete with the result that the effect of the strength increase of the concrete is lowered.
- the form is not disassembled after concrete is injected into the form.
- the concrete is cured through a long hydration reaction in which moisture contained in the concrete is slowly evaporated until approximately 28 days elapses after the concerted has been injected into the form.
- the strength of a concrete structure using the form panel system according to the present invention is 30 % higher than that of a conventional reinforced concrete structure obtained through a disassembling and removing process of the wood or steel plate forms.
- the distance between the compression cement boards is prescribed by means of the metal plate studs disposed between the compression cement boards. Simultaneously, the vertically or horizontally disposed reinforcing bars are replaced with the metal plate studs. Consequently, the concrete structure with a correct thickness is formed without using additional structural members, and a reinforcing bar arranging process is eliminated.
- the one-plane connection members prevent concrete from leaking from the connections between the compression cement boards or the foamed plastic panels.
- the panels are connected to each other while the spaces between the panels are not obstructed by means of the one-plane connection members.
- concrete injected into one side of the form panel system moves along the spaces between the panels such that the concrete is wholly filled in the form panel system. Consequently, the concrete is easily and conveniently injected and distributed.
- the same effect is accomplished by means of the opening formed at the two-plane connecting members.
- the opposite panels are connected to each other by means of the two-plane connecting members, and simultaneously, the panels arranged on the same plane are connected to each other by means of the two-plane connecting members.
- the spaces between the panels communicate with each other through the openings of the two-plane connecting members.
- the metal plate studs used in the present invention are provided with the openings.
- horizontal reinforcing members such as reinforcing bars or steel pipes
- the openings are formed such that their widths are gradually decreased toward the lower parts thereof, i.e., in the direction in which the gravity is applied. Consequently, when the reinforcing bars inserted through the openings of the metal plate studs, the reinforcing bars go down into the narrow parts of the openings due to the weights of the reinforcing bars, and thus the reinforcing bars are fitted in the openings by the wedge effect. When the reinforcing bars are slightly pushed from above, the reinforcing bars are securely fitted in the openings of the metal plate studs.
- the reinforcing bars which serve as horizontal reinforcing members when concrete is injected, are not displaced from their original positions without connecting the reinforcing bars by means of wires.
- the openings of the metal plate studs are formed such that the size of each of the openings of the metal plate studs is larger than the sectional area of each of the horizontal reinforcing members. Consequently, the concrete freely moves in the spaces between the panels through the empty parts of the openings of the metal plate studs after the horizontal reinforcing members are inserted in the openings of the metal plate studs.
- the compression cement boards are reinforced with the linear cement board reinforcing members attached horizontally or vertically to the insides of the compression cement boards.
- each of the metal plate studs may be formed with a multiple of the height of each of the compression cement boards. Consequently, it is possible that the compression cement boards are connected to each other in a double-layered structure.
- the metal plate studs and foamed plastic studs may be formed in asymmetric shapes or irregular shapes such that the present invention is applicable to a retaining wall structure or a bank structure.
- Pipes are inserted through the openings formed at the metal plate studs, the I-type foamed plastic connecting members, and the two-plane connection members. Consequently, an electric work, a telephone line work, and a communication line work are performed simultaneously when the wall is formed.
- various-shaped opening parts between the compression cement boards may be covered by means of a cover. Consequently, a door frame and a window frame may be easily formed.
- the form panel according to the present invention is manufactured, without limits to its shape and size, using a computerized or automatically controllable heating wire-type forming machine instead of the foam forming machine or the mold. Consequently, mass production of the form panel is possible, and therefore, productivity is improved together with improved formatively pleasing appearance.
- form-shaped supporting plates and supporting posts are not used when bottoms between floors and girders of the building are constructed. Consequently, time and costs are reduced.
- the reinforcing bars are prevented from drooping when they are used, and constant heights and distances are maintained, whereby a stable structure is obtained.
- a foundation wall and a wall of the structure may be previously manufactured at a manufacturing factory.
- the form panels previously disposed at both sides of the form panel system according to the present invention serve as the foamed plastic heat insulating materials. Consequently, a process of applying mortar to the concrete and attaching heat insulating materials is eliminated, which reduces labor and costs. Since the heat insulating materials are disposed at both sides of the form panel system, the heat insulation property is increased, and coefficient of overall heat transmission is decreased. Consequently, the energy saving effect of the present invention is excellent.
- the fiber-shaped mesh-reinforced compression cement boards with excellent strength, adhesive property, water resistance, and inflammability are attached to both sides of the panel. Consequently, various decoration finishing materials, such as tile, timber, marble, wall paper, etc., are easily and conveniently applicable to the form panel system according to the present invention.
