Description

Prefabricated flat wooden system module

[0001] The present invention relates to a wooden module for use in construction, and more particularly, to a prefabricated flat-type wooden system module composed of fire-retardant treated wood.

[0002] Wood is widely used in eco-friendly structures requiring earthquake resistance, durability, fire resistance, and / or insulation. In particular, wood boasts superior tensile and compressive strength per unit weight compared to steel or concrete. Cross-laminated timber (CLT), made by gluing together cut pieces of wood, and laminated veneer lumber (LVL), made by laminating veneers, are widely used as building materials.

[0003] In the case of coniferous wood, thermal decomposition occurs in the event of a fire. When the temperature exceeds 200℃, the carbon layer turns black and forms a char layer at approximately 0.6mm per minute and 36mm per hour, as shown in Figure 1. This char layer has a minimum thickness of approximately 0.6mm per minute, which can withstand approximately 10 minutes at 305℃. It thickens over time when exposed to fire, blocking heat transfer into the wood. Consequently, the char layer suppresses the generation of volatile gases and blocks heat transfer, thereby stopping combustion. In other words, due to the action of the char layer, wood offers safer performance than metal in the event of a fire. Therefore, wooden structures can secure evacuation time in the event of a fire, ensure safety and visibility for firefighting, and delay the spread of fire.

[0004] Meanwhile, when wood is used as a building material, metal fasteners like screws and nails can damage the joints. Consequently, with prolonged use, the joints weaken, shortening the wood's service life.

[0005] On the other hand, Korean Patent Registration No. 10-2069534 and Korean Patent Registration No. 10-1055418 relate to wooden columns made of solid wood, and most of the connecting parts are connected by flange joints.

[0006] However, since these conventional technologies are composed of raw wood, they cannot strengthen the strength of wood or enhance the fire resistance of wood, and they cannot prevent damage caused by metal fasteners.

[0007] In addition, since the connection points of the wooden columns that make up the ramen-style frame are mostly connected with flange joints, they are vulnerable to earthquakes and vibrations, and since the precast concrete floor slab is installed on top of the horizontal plate slab of the frame, it is impossible to buffer inter-floor noise.

[0008] Additionally, due to lack of rigidity, it cannot be used as a high-rise load-bearing wall or as a mortar-cured floor material or slab.

[0009] The present invention was created to solve the above-mentioned problems, and the purpose is to provide a prefabricated flat-panel wooden system module that can delay the spread of fire by securing flame retardancy, can prevent or suppress shearing and collapse by structurally reinforcing metal reinforcing members having lengths, and can prefabricatedly connect wood to other reinforcing members, other wood, or other structures by screw-joining without damaging the wood.

[0010] In particular, the purpose is to provide a prefabricated flat-panel wooden system module that can maximize the cross-sectional area and elasticity of long-formed reinforcing materials and reinforce the connecting portions of parts for prefabricated connection to reinforce the rigidity of the connecting portions.

[0011] Another purpose is to provide a prefabricated flat-panel wooden system module in which reinforcing materials are inserted long enough to reinforce the rigidity of the wood along the longitudinal direction and to reinforce the rigidity of the connecting portions of column-shaped wood.

[0012] Another purpose is to provide a floor plate that is secured to a slab with planar wood and to provide a prefabricated flat wooden system module that can buffer interfloor noise.

[0013] In addition, another purpose is to provide a prefabricated flat-panel wooden system module having components in which planar woods are connected in a orthogonal state by assembly and a portion of the connected woods is supported.

[0014] In addition, another purpose is to provide a prefabricated flat wooden system module to which a member that enhances the heat resistance of the metallic reinforcement is additionally attached.

[0015] In addition, another objective is to provide a high-strength, prefabricated flat-panel wooden system module by further reinforcing rigidity through functional, high-performance fibers.

[0016] To achieve the above-described object, the present invention provides a prefabricated flat-panel wooden system module comprising: a wooden building material composed of a column-shaped wooden post or a plate-shaped wooden board; a metal reinforcing member having a rigidity stronger than the wooden building material, formed long and inserted along the longitudinal or transverse direction of the wooden building material, and reinforcing the rigidity of the wooden building material through its rigidity; and a connector installed at an end of the metal reinforcing member inserted into the wooden building material to connect the wooden building material to another wooden building material or a structure in the vicinity.

[0017] The above metal reinforcing material is characterized in that it is a steel pipe reinforcing bar that is integrally embedded in the wooden building material by being inserted and fixed in a reinforcing material insertion groove formed in the wooden building material and has a hollow portion formed along at least a portion of the length direction.

[0018] The connector comprises: a metal bracket, which is fixed to an end of the wood building material by being connected to the steel pipe reinforcing bar of the metal reinforcing material inserted into the wood building material, and which is formed of at least one of a flat plate, an angle, a channel, or a square tube; a male screw member, which is formed of either a headless bolt having a screw shaft passing through the bracket while being fixed to the end of the steel pipe reinforcing bar, or a nipple bolt having a screw shaft passing through the bracket and being connected to the end of the steel pipe reinforcing bar; and a female screw member, which is detachably fastened to the male screw member, which is formed of either a nut fastened to the screw shaft of the headless bolt, or a female screw formed on the inner surface of the steel pipe reinforcing bar and to which the screw shaft of the nipple bolt is fastened.

[0019] The above screw member is characterized in that the screw shaft is inserted into the end of the steel pipe reinforcement and is permanently connected through welding, or is detachably screw-connected to the end of the steel pipe reinforcement, thereby being integrally fixed to the end of the steel pipe reinforcement.

[0020] The above-mentioned wooden post or the above-mentioned wooden board of the above-mentioned wooden building material is characterized in that it is composed of a plurality of wooden panels that are joined in an overlapping state, and a plurality of reinforcing material insertion grooves into which the steel pipe reinforcing bars are inserted are formed penetrating in a spaced state along the length direction or the width direction.

[0021] The present invention further includes a coupler that connects the wooden posts in an aligned state to provide a frame through the wooden posts.

[0022] The above coupler includes a fitting projection integrally provided on the flat plate of the bracket fixed in a close state to the lower end of the wooden post and protruding downward from the flat plate; and a fitting tube vertically installed along the length direction inside another wooden post installed at the lower end of the wooden post and into which the fitting projection is fitted and restrained.

[0023] The present invention further includes an H-shaped beam installed in another wooden post installed at the lower portion of the wooden post and having the fitting tube.

[0024] The present invention further includes a square socket bracket having a bolting hole for fastening the male screw member and the female screw member and a through hole through which the insertion projection passes.

[0025] The above-mentioned wooden board of the above-mentioned wooden building material is installed in a laminated state on the upper part of a slab horizontally arranged between the wooden posts that are connected by the coupler to form a frame, and a reinforcing mesh is installed along the upper surface area, and mortar is poured on the reinforcing mesh to provide a soundproof floor plate on the upper part of the slab.

[0026] The above wooden board is characterized in that the angles of the above brackets are installed along the edges on all sides, and the leakage of the mortar poured into the above reinforcing mesh is prevented through the angles.

[0027] The wooden board providing the above floor plate is characterized in that it provides a floor plate integrally equipped with a damper that buffers the impact of the upper portion on which the mortar is poured.

[0028] The damper comprises: a lead screw vertically installed to be able to pivot on the wooden board; an elevation guide having a nut that is connected to the lead screw and moves vertically along the lead screw and is integrally fixed to the wooden board to elevate the wooden board while moving; a spring installed at a lower portion of the wooden board that is elevated by the nut of the elevation guide and elastically supports the wooden board that is elevated by the nut to cushion impact; and an expansion guide that guides the expansion of the spring to prevent the spring from being detached.

[0029] The above wooden board can be guided to rise and fall by a rising guide that guides the rising and falling by the lead screw.

[0030] The above wooden board is characterized in that the lifting guide and the expansion guide are configured as pipes or rods and are installed vertically so as to be aligned with the lower surface, thereby guiding the lifting by the lead screw or the expansion by the spring.

[0031] The above wooden board is characterized in that it is installed on at least both sides of the angle or the channel of the bracket in which a through hole is formed through which the screw shaft of the head bolt or the U-bolt of the male screw member passes, and is integrally fixed to the angle or the channel by fastening the male screw member and the female screw member to provide a wall.

[0032] The above wooden board is characterized in that a bolting plate, to which a bolt or nut is fastened, is installed perpendicularly to the angle of the bracket or the end of the channel, and a support bar is installed in a penetrating state through the bolting plate, so that the end where the bracket is installed is supported by the support bar through the bracket.

[0033] The wooden board installed on at least both sides of the angle or the channel is characterized in that it is connected to an angle or channel of another bracket in the vicinity through an additional bracket in the form of a channel or a square tube, by being connected by bolting to the bolting plate installed perpendicular to the angle or the channel of the bracket.

[0034] As described above, the present invention can delay the spread of fire by treating the wooden building material with a flame retardant, and can strengthen the fire resistance and vertical or horizontal strength of columns, beams, walls, floors, ceilings, etc. by structurally reinforcing the metal reinforcing material composed of steel pipes, thereby preventing or suppressing shearing and collapse, and can connect the wood to other reinforcing material, other wood, or other structures by screwing without damaging the wood by connecting through a connector, thereby improving the convenience of construction.

[0035] In particular, since the metal reinforcing material is made of hollow steel pipes, the cross-sectional area and elasticity can be secured to the maximum extent, so it can respond flexibly to earthquakes or vibrations, and since a part of the screw shaft of the headless bolt or nipple bolt is inserted into the steel pipe rebar and the outer surface is supported by the inner surface of the steel pipe rebar, the rigidity of the connection part of the steel pipe rebar where the headless bolt or nipple bolt is connected is reinforced.

[0036] In addition, since the steel pipe reinforcement is arranged along the length or width direction of the wooden building material, the rigidity of the wood can be reinforced, and since a coupler is installed at the connection point of the wooden posts, the rigidity of the connection point can be reinforced.

[0037] Additionally, a mortar-cast floor can be provided using wooden boards, and dampers can be provided on these wooden boards to buffer interfloor noise.

[0038] In addition, since the wooden boards are connected in a right-angled manner by angles or channels, they can be easily connected at right angles, and since the angles or channels of the wooden boards connected in this way have support bars installed, the load on the end surfaces of the wooden boards can be supported through the support bars.

[0039] In addition, since a heat-resistant fabric is installed on the outer surface of the steel pipe reinforcing bar, the heat resistance of the steel pipe reinforcing bar can be enhanced.

[0040] In addition, a wood board reinforced with steel pipes can provide a high-strength wood board because the wood board is further reinforced with fiber-reinforced polymer and a shielding plate.

[0081] Hereinafter, a prefabricated flat wooden system module according to an embodiment of the present invention will be described with reference to the attached drawings.

[0082] The prefabricated flat wooden system module according to an embodiment of the present invention is composed of a wooden building material (100), a metal reinforcing material made of steel pipe reinforcing bars (60), and a connector described below, as shown in FIGS. 4 to 8 and FIGS. 26 to 31.

[0083] The wooden building material (100) is composed of a column-shaped wooden post (P) or a plate-shaped wooden board (B), as illustrated in FIGS. 8 and 26. The wooden post (P) or the wooden board (B) is manufactured in a column-shaped or plate-shaped form by a plurality of wooden panels (PN) that are joined in an overlapping manner as illustrated. The wooden panels (PN) may be formed in a manner in which the fiber directions cross vertically or overlap in one direction and are joined in a laminated manner, and are flame-retardant treated with a flame retardant solution by the method described below. The plurality of wooden panels (PN) are joined to each other in a facing state using a conventional flame-retardant adhesive or a conventional fastener such as a bolt to form a single body. When the wooden panels (PN) are attached with an adhesive, the adhesive is applied to at least one of the opposing surfaces (e.g., one side surface), and the opposing surfaces are attached to each other as a single body by the adhesive. Since this attachment method is a conventional method that can be easily understood by those skilled in the art, a detailed description thereof will be omitted.

[0084] As shown in Fig. 8, the wooden post (P) or wooden board (B) of these wooden building materials (100) has a plurality of reinforcing material insertion grooves (H) formed spaced apart along the length or width direction for inserting the steel pipe reinforcing bars (60) described later.

[0085] The metal reinforcing material has a stronger rigidity than the wooden building material (100) and is inserted along the longitudinal direction or the width direction of the wooden building material (100) to reinforce the rigidity of the wooden building material (100) through its rigidity. The metal reinforcing material is composed of a plurality of steel pipe reinforcing bars (60) as illustrated in FIGS. 8 to 10 and FIGS. 26 to 29 to ensure lightness. As illustrated, the steel pipe reinforcing bar (60) has a hollow portion formed in at least a portion of the longitudinal direction and is inserted into the aforementioned reinforcing bar insertion groove (H) formed in the wooden building material (100) and fixed, thereby being integrally embedded in the wooden building material (100). That is, the steel pipe reinforcing bar (60) is composed of a steel pipe and is inserted into the reinforcing bar insertion groove (H) and arranged in a spaced state in the wooden building material (100). The steel pipe reinforcing bars (60) can be attached to the inside of the reinforcing insertion groove (H) using a conventional flame-retardant adhesive. As described above, the steel pipe reinforcing bars (60) are configured in multiple pieces and arranged spaced apart along the longitudinal or transverse direction of the wooden building material (100), thereby reinforcing the overall rigidity of the wooden building material.

[0086] The connector is installed at the end of a metal reinforcing member inserted into a wooden building material (100) to connect the wooden building material (100) to another wooden building material (100) in the vicinity or to a structure in the vicinity. That is, the connector is installed at the end of a steel pipe reinforcing bar (60) to connect a wooden post (P) or a wooden board (B) to another wooden post (P) or wooden board (B) in the vicinity or to a structure such as a wall or floor in the vicinity. The connector is composed of a metal bracket (80), a male screw member (70), and a female screw member (N, 60a) as described below.

[0087] The bracket (80) is composed of at least one of a flat plate (81) as shown in FIGS. 12 and 13, an angle (83) as shown in FIGS. 31 and 32, a channel (85) or a square pipe (80a) as shown in FIGS. 33 to 35. This bracket (80) is fixed to an end of the wooden building material (100) by being joined to a steel pipe reinforcing bar (60) inserted into a wooden post (P) or wooden board (B) of the wooden building material (100) as shown in FIGS. 5, 21, or 31 to 35, through a male screw member and a female screw member described below.

[0088] The screw member (70) is composed of either a headless bolt (71) whose screw shaft penetrates the bracket (80) and is fixed to the end of the steel pipe reinforcing bar (60) as shown in FIGS. 5 and 7, or a nipple bolt (73) whose screw shaft penetrates the bracket (80) and is connected to the end of the steel pipe reinforcing bar (60) as shown in FIGS. 11 and 31.

[0089] The female screw member is composed of either a nut (N) fastened to the screw shaft of a head bolt (71) as shown in Fig. 5, or a female screw (60a) formed on the inner surface of a steel pipe reinforcing bar (60) as shown in Fig. 11 and fastened to the screw shaft of a nipple bolt (73).

[0090] Here, when the aforementioned screw member (70) is composed of a headless bolt (71), a portion of the screw shaft is inserted into the end of the steel pipe reinforcing bar (60) as illustrated in FIG. 27 and then permanently connected through welding. And, when the screw member (70) is composed of a nipple bolt (73), the screw shaft is detachably screw-connected to the end of the steel pipe reinforcing bar (60) as illustrated in FIGS. 11 and 21. Therefore, the screw member (70) is integrally fixed to the end of the steel pipe reinforcing bar (60).

[0091] Meanwhile, the aforementioned wood panel (PN) is cut from a log into a board shape as shown in (a) of FIG. 36 for flame retardant treatment, and then is placed in a vacuum tank (T) as shown in (b) of FIG. 36. Then, the moisture contained in the wood panel (PN) is removed as the vacuum tank (T) is evacuated by the vacuum pump (PM). Subsequently, the wood panel (PN) is immersed in a flame retardant solution as a typical wood flame retardant solution is filled into the vacuum tank (T) where the moisture is removed and the vacuum is released as shown in (c) of FIG. 36. Subsequently, the wood panel (PN) is pressurized by air pressure as the vacuum pump (PM) rotates in reverse or an unillustrated pneumatic pump (e.g., a compressor) is operated to supply air to the interior of the vacuum tank (T). That is, the wood panel (PN) is pressurized by air as the internal pressure of the vacuum tank (T) increases due to the air supply. Wood panels (PN) readily absorb the flame retardant under pressure. These wood panels (PN) may be pressurized in the manner described above after the flame retardant has been removed from the vacuum tank (T). The flame retardant is removed after the wood panels (PN) have been sufficiently immersed in the water for a sufficient period of time (e.g., 10 minutes to 24 hours).

[0092] Thereafter, the wood panel (PN) is dried by a heater (H) as illustrated in (d) of Fig. 36. At this time, the wood panel (PN) can be dried inside the vacuum tank (T) for about 15 to 30 minutes with hot air of about 60 to 70°C by the heater (H) built into the vacuum tank (T) as illustrated.

[0093] Next, the wood panel (PN) is cooled slowly inside a vacuum tank (T) to prevent warping due to slow cooling, and then left at room temperature for further slow cooling, as shown in (e) of Fig. 36. At this time, the wood panel (PN) is cooled slowly at room temperature for approximately 30 minutes to 3 hours.

[0094] Here, the aforementioned wood panel (PN) is evacuated for about 10 to 15 minutes at a pressure of about 720 mmHg to 760 mmHg depending on the type (characteristics) of the wood. And, the wood panel (PN) is evacuated at about 2 to 5 kg / cm depending on the type of wood. 2 It is pressurized for 10 to 15 minutes.

[0095] The embodiment of the present invention as described above delays fire as the wood panel (PN) is pressurized and flame-retardant treated, and since it is not easily combusted by the flame retardant (flame retardant liquid), the generation of toxic substances from combustion can be suppressed to the greatest extent possible, and even if ignited, the surface is carbonized to form a carbonized layer, thereby preventing the spread of fire.

[0096] Meanwhile, after the flame retardant treatment process is completed, the wood panel (PN) has an adhesive applied to one side where a reinforcing material insertion groove (H) is formed. Then, the wood panel (PN) has a steel pipe reinforcing bar (60) as described above inserted into the reinforcing material insertion groove (H). The wood panel (PN) is integrally joined by closely facing another wood panel (PN) where the reinforcing material insertion groove (H) is formed. Accordingly, a plurality of wood panels (PN) provide a wood building material (100) in which the steel pipe reinforcing bar (60) is inserted and embedded (placed) as illustrated in FIGS. 8 and 27.

[0097] In this embodiment of the present invention, depending on the size (length, width and thickness) of the wood panel (PN), it can be configured as a column-shaped wood post (P) as shown in FIGS. 5 and 7, or alternatively, it can be configured as a plate-shaped wood board (B) as shown in FIGS. 21 and 26. In the embodiment of the present invention, the wood post (P) is used as a column or beam, and the wood board (B) is used as a wall, flooring or ceiling material.

[0098] Meanwhile, as shown in FIGS. 8 and 27, the steel pipe reinforcing bar (60) may have a heat-resistant fabric (40) made of a flame-retardant material attached to the outer surface thereof using a conventional flame-retardant adhesive. The heat-resistant fabric (40) may be composed of conventional ceramic wool. Ceramic wool is a high-temperature insulating material made of ceramic fibers and is also called ceramic wool, and is stored in a roll form due to the flexibility of the fiber material. Such ceramic wool is easy to work with due to its flexibility, which can shorten the work time, provides excellent insulation effect, and has a heat resistance of about 1,260°C to 1,600°C depending on the manufacturing method or mixing components. The heat-resistant fabric (40) is wound and attached to the surface of the steel pipe reinforcing bar (60) using the aforementioned adhesive. That is, the heat-resistant fabric (40) is wound and attached to the outer surface of the reinforcing material (60) after the adhesive is applied to the surface of the steel pipe reinforcing bar (60). Accordingly, the steel pipe reinforcing bar (60) is inserted and fixed between the wooden panels (PN) by adhesive with the heat-resistant fabric (40) attached.

[0099] The heat-resistant fabric (40) may be attached so as to make surface contact with the steel pipe reinforcing bar (60) rather than being wound around it, as illustrated in FIGS. 39 and 40. To this end, the heat-resistant fabric (40) is configured as a pair facing each other, as illustrated, and is interposed in a planar state between the wood panels (PN) of the wood board (B) facing each other with the reinforcing insertion grooves (H). These heat-resistant fabrics (40) are bonded on both sides of the steel pipe reinforcing bar (60) with the steel pipe reinforcing bar (60) as the center, using the flame-retardant adhesive described above. Therefore, the heat-resistant fabric (40) shields and insulates the outer circumferential surface of the steel pipe reinforcing bar (60) by wrapping it. This attachment method shortens the winding time because the heat-resistant fabric (40) is not wound around the steel pipe reinforcing bar (60).

[0100] Here, the aforementioned steel pipe reinforcing bar (60) has adhesive insertion grooves (63) or belt protrusions formed at equal intervals along the longitudinal direction on the outer surface thereof, as illustrated in FIG. 11, to enhance the adhesive strength to the heat-resistant fabric (40). The steel pipe reinforcing bar (60) receives adhesive between the adhesive insertion grooves (63) or belt protrusions. The steel pipe reinforcing bar (60) is received in the adhesive insertion grooves (63) and the adhesive accumulated therein is provided at equal intervals to the heat-resistant fabric (40) on the outer surface thereof, thereby firmly attaching the heat-resistant fabric (40). Therefore, the steel pipe reinforcing bar (60) has an outer surface that is insulated by the heat-resistant fabric (40), thereby enhancing heat resistance in the event of a fire.

[0101] The embodiment of the present invention configured as described above provides a frame-type frame as illustrated in FIGS. 4 and 5 through the wooden posts (P) when the wooden building material (100) is configured with wooden posts (P) as illustrated in FIGS. 5 and 7. At this time, a plurality of wooden posts (P) are connected to each other in a vertical and / or horizontal state by fastening the male screw member (70) and female screw member (N, 60a) described above after the bracket (80) is installed as illustrated. Accordingly, the wooden posts (P) form a frame-type frame as illustrated.

[0102] Here, the wooden posts (P) forming the frame are installed with a bracket (80) of a flat plate (81) at the lower end forming a vertical plane as shown in Fig. 5 by bolting. The wooden post (P) on which the flat plate (81) is installed needs to have an additional bracket (80a) in the shape of a square tube installed at the lower end where the flat plate (81) is provided as shown. The additional bracket (80a) is provided with a bolt hole for the penetration of a headless bolt (71) that is protrudingly installed in the steel pipe reinforcing bar (60) of the wooden post (P) as shown.

[0103] As shown in Fig. 5, the wooden post (P) is integrally attached to the additional bracket (80a) by fastening the nut (N) of the female screw member after the headless bolt (71) passes through the additional bracket (80a). Accordingly, the wooden post (P) is integrally connected to the additional bracket (80a) with the headless bolt (71) and nut (N) passing through and fastening the additional bracket (80a) as the center, thereby forming a frame-type frame.

[0104] Meanwhile, as described above, the wooden posts (P) that constitute the frame are rigidly connected in an aligned state by a coupler. This coupler is composed of a fitting projection (81c) and a fitting tube (81b), as illustrated in FIG. 5 and FIGS. 12 to 16.

[0105] The insertion projection (81c) is formed in the shape of a rod or pipe as illustrated in FIGS. 5 and 13 to 14, and is integrally provided on the flat plate (81) of the bracket (80) that is fixed in close contact with the lower end of the wooden post (P) and protrudes downward from the flat plate (81). The insertion projection (81c) passes through the aforementioned square tube-shaped additional bracket (80a) as illustrated and is inserted into the insertion tube (81b) described later. The insertion tube (81b) is formed of a pipe or a ring as illustrated and is installed vertically along the length direction inside another wooden post (P) that is installed at the lower end of the wooden post (P). The insertion projection (81c) described above is inserted into the insertion tube (81b) as illustrated. Accordingly, the insertion tube (81b) restrains the insertion projection (81c) through its inner circumferential surface. Accordingly, the wooden posts (P) aligned in a straight line as shown are firmly connected by the combination of the insertion projection (81c) and the insertion tube (81b), and can be firmly maintained in an aligned state even during vibration or earthquake.

[0106] Here, the aforementioned fitting tube (81b) is vertically installed in the middle portion of the beam (81a) as illustrated in the drawings, when an H-shaped beam (81a) is installed in the lower wooden post (P) as illustrated in FIGS. 12 to 14. The fitting tube (81b) is mounted in the middle portion of the beam (81a) by welding or bolting. It is preferable that the fitting tube (81b) be fixed to the cut middle portion of the beam (81a) as illustrated so that both sides of the fitting projections (81c) are supported by the beam (81a) and the load is evenly transferred. That is, the beam (81a) may be cut in the middle portion so that the fitting tube (81b) is installed in the middle portion as illustrated.

[0107] In the embodiment of the present invention configured as described above, as shown in FIG. 5, a flat plate (81) of a bracket (80) having a fitting projection (81c) provided at the lower end of an upper wooden post (P) is bolted, and then the upper wooden post (P) is installed on the upper side of a square-shaped additional bracket (80a), and the lower wooden post (P) having the fitting tube (81b) described above is installed on the lower side of the additional bracket (80a). At this time, the fitting projection (81c) passes through the additional bracket (80a) and is fitted into the fitting tube (81b). Then, the headless bolts (71) provided on the upper and lower wooden posts (P) pass through the additional bracket (80a), and then the nuts (N) of the female screw members are fastened. Accordingly, the wooden posts (P) are fixed to the upper and lower sides of the additional bracket (80a) in an aligned state.

[0108] The wooden posts (P) are aligned horizontally on both sides of the additional bracket (80a) as illustrated in FIG. 5. At this time, the wooden posts (P) are integrally fixed to the additional bracket (80a) by fastening the head bolts (71) to the nuts (N) as described above. Accordingly, the wooden posts (P) are installed vertically and horizontally as illustrated in FIG. 4 and FIGS. 15 to 18, thereby providing a frame-type frame.

[0109] In this way, the frame provided by the wooden posts (P) is installed with a slab (SL) as shown in FIGS. 15 to 18. The slab (SL) is made of planar wood as shown and is installed in a horizontal state. The slab (SL) can be installed in a horizontal state by being secured to the horizontal wooden posts (P) in a beam shape. At this time, the flat plate (81) of the aforementioned bracket (80) is fixed to the slab (SL) by bolting with a bolt (BT) at a portion protruding outward from the wooden posts (P) as shown in FIGS. 16 to 18.

[0110] Meanwhile, the wooden board (B) configured in a plate shape as illustrated in FIGS. 20 and 26 provides a floor plate (110) to be installed on the slab (SL) described above as illustrated in FIGS. 18 and 19. That is, the wooden board (B) provides a floor plate (110) to be installed in a laminated state on the slab (SL) horizontally arranged between wooden posts (P) that are connected by the coupler described above to form a frame.

[0111] To this end, a wooden board (B) is provided with a reinforcing mesh (M) along the upper surface area as illustrated in FIGS. 19 to 23, and mortar (C) is poured onto the reinforcing mesh (M) to provide a soundproof floor plate (110) on the upper portion of the slab (SL). As illustrated in FIG. 21, the wooden board (B) has angles (83) of brackets (80) installed along the four edges instead of a conventional formwork, thereby preventing leakage of mortar (C) poured onto the reinforcing mesh (M) through the angles (83).

[0112] Here, the aforementioned reinforcing mesh (M) is spaced apart from the upper surface of the wooden board (B) as multiple spacers (110) are installed on the wooden board (B) as illustrated in FIG. 20, thereby providing an inflow space for mortar (C) on the upper surface of the wooden board (B). The spacers (110) are installed on the upper surface of the wooden board (B) as illustrated, thereby providing a protrusion on the upper surface of the wooden board (B), and by supporting the lower portion of the reinforcing mesh (M), easily space the reinforcing mesh (M) from the upper surface of the wooden board (B). The spacers (110) may be configured, for example, as illustrated in an enlarged form in FIG. 20, with a seat (110b) that is seated on the upper surface of the wooden board (B) and a protrusion (110a) that protrudes from the upper portion of the seat (110b). The spacer (110) is stably fixed to the upper part of the wooden board (B) by the protrusion (110a) via the seat (110b), and easily supports the reinforcing mesh (M) by the protrusion (110a). The spacer (110) can be manufactured by bending a conventional reinforcing bar into a structure as shown.

[0113] These spacers (110) and reinforcing mesh (M) are metallic structural materials that are installed on top of a wooden board (B), embedded in mortar (C) poured into the wooden board (B), and integrally bonded to the cured mortar (C) to supplement the structural rigidity of the mortar. Accordingly, since the spacers (110) and reinforcing mesh (M) are fixed to the inside of the hardened mortar (C), the wooden board (B) reinforces the strength of the hardened mortar (B) while preventing cracks. Accordingly, the wooden board (B) provides a floor plate (110) with secured strong rigidity.

[0114] Meanwhile, as described above, the wooden board (B) providing the floor plate (110) can provide a floor plate (110) with a conventional heating pipe (not shown) piped into the portion where the mortar (C) is poured, as shown in FIGS. 19 to 23. The heating pipe is piped between the reinforcing meshes (M) before the mortar (C) is poured.

[0115] And, this wooden board (B) can also provide a floor plate (110) integrally equipped with a damper (120) that cushions the impact of the portion where the mortar (C) is installed, as shown in FIGS. 18 to 19 and 22 to 23. To this end, as shown, the wooden board (B) is fixed integrally with the lead screw (LS) of the damper (120) so as to be able to pivot, and the lead screw (LS) is raised and lowered by rotation by the nut (N) to which the lead screw (LS) is fastened, and as it is elastically supported by the springs (S1) installed on the upper part of the slab (SL), the impact is cushioned by the expansion and contraction of the springs (S1), thereby alleviating inter-floor noise. At this time, the lead screw (LS) is rotated as the head installed so as to be exposed to the mortar (C) is rotated, thereby raising and lowering the wooden board (B).

[0116] As illustrated in Fig. 23, the wooden board (B) is guided to rise and fall by a rising guide (123) when raised and lowered by a lead screw (LS), and the expansion and contraction of the spring (S1) is guided by an expansion guide (121) fitted to the spring (S1). The rising and falling guide (123) is composed of bushes or cylindrical pipes (123a, 123b) that are aligned with each other as illustrated. Therefore, the wooden board (B) is raised and lowered smoothly as the aligned pipes (123a, 123b) are prevented from coming off during the raising and lowering.

[0117] The expansion guide (121) is configured with a bush-shaped pipe (121a) and a vertical rod (121b) that are fitted with a spring (S1) on the outer surface as shown in Fig. 23 to prevent the spring (S1) from coming off. Accordingly, when the spring (S1) expands due to an impact from the upper side, the wooden board (B) absorbs the impact through the spring (S1) while smoothly moving up and down since the pipe (121a) and rod (121b) that are fitted with each other maintain the aligned state.

[0118] Such a wooden board (B) may also be provided with an additional spring (S2) on the inside of the aforementioned pipes (123a, 123b) as illustrated in FIG. 23. This additional spring (S2) is installed in a cap- or cup-shaped spring sheet as illustrated, and when positioned to the upper portion of the pipes (123a, 123b), it can additionally absorb shock by expanding together with the spring (S1) when an impact is applied to the upper portion. Accordingly, the wooden board (B) can more smoothly buffer interfloor noise caused by impact.

[0119] Here, the wooden board (B) of the aforementioned floor plate (110) is configured with a plurality of the aforementioned dampers (120) as illustrated in FIG. 19 and installed spaced apart along the lower portion. Accordingly, the wooden board (B) can be adjusted horizontally as a whole while being raised and lowered by the lead screw (LS). That is, the horizontality of the floor plate (110) is adjusted by the lead screw (LS).

[0120] Meanwhile, as illustrated in FIGS. 30 to 35, the wooden board (B) may be configured in multiples and installed on at least both sides of the angle (83) or channel (85) of the bracket (80) having a through hole formed therein through which the screw shaft of the headless bolt (71) or the screw shaft of the U-bolt (73) of the male screw member (70) passes. That is, the wooden board (B) may be installed on both sides of the angle (83) or the channel (85). The wooden board (B) is integrally fixed to the angle (83) or the channel (85) by fastening the male screw member (70) and the female screw member (N, 60a) to provide a wall. In addition, the wooden board (B) may be installed on both sides of the angle (83) or the channel (85) as illustrated in FIG. 33 to provide a wall and a floor together.

[0121] Here, the angle (83) or channel (85) of the aforementioned bracket (80) is installed in a orthogonal state with a bolting plate (83a, 85a) to which a bolt or nut is fastened at the end, as shown in FIGS. 30 to 35, and a support bar (89a) is installed in a penetrating state in the bolting plate (83a, 85a). Accordingly, the end of the wooden board (B) where the bracket (80) is installed is supported by the support bar (89a) through the bracket (80). Accordingly, the wooden board (B) can be firmly maintained in a state of being fixed to the bracket (80) by being supported by a load on the support bar (89a).

[0122] Meanwhile, as illustrated in FIGS. 30 to 35, the bracket (80) is equipped with an additional bracket (80a) in the form of a channel or square tube on the bolting plates (83a, 85a) in the aforementioned orthogonal state. As illustrated, this additional bracket (80a) is connected to the angle (83) or channel (85) of another bracket (80) in the vicinity by bolting. Accordingly, a plurality of adjacent angles (83) or channels (85) are firmly and integrally connected through the additional bracket (80a).

[0123] As shown, this additional bracket (80a) can have a through hole formed through which the aforementioned support bar (89a) passes. Accordingly, the support bar (89a) can be installed in a through hole state even when the additional bracket (80a) is provided.

[0124] The embodiment of the present invention configured as described above provides a frame-type frame in which wooden posts (P) are installed vertically and horizontally to the additional bracket (80a) with the additional bracket (80a) as the center in the manner described above, as shown in FIG. 5. At this time, the wooden posts (P) are aligned in a row, and the fitting projections (81c) of the coupler are coupled to the fitting tube (81c) as shown in FIGS. 13 and 14. Accordingly, the wooden posts (P) aligned in a row are firmly maintained in a connected state. Accordingly, even if an earthquake or vibration is transmitted to the wooden posts (P) connected in an aligned state, the fitting projections (81c) are not separated at the connection portion due to the coupling of the fitting tube (81c).

[0125] As shown in FIGS. 4 and 15, the wooden posts (P) are provided with a slab (SL) at the connection portion as the aforementioned wooden board (B) is installed horizontally at the vertical connection portion. As shown in FIGS. 18 and 22 to 23, the wooden posts (P) are provided with a floor plate (110) made of the aforementioned wooden board (B) on the upper portion of the slab (SL). In addition, the wooden posts (P) are provided with a wall body made of the wooden board (B) as shown in FIGS. 24 to 25 and 33. Accordingly, the frame made of the wooden posts (P) is provided with a slab (SL), a floor plate (110), and a wall body to form a building as shown in FIG. 3. This frame provides a wooden building as a roof is installed on the upper portion as shown in FIG. 2.

[0126] Here, the wooden board (B) providing the aforementioned floor plate (110) is leveled by a lead screw (LS) of a damper (120) as illustrated in FIG. 19 and FIG. 23, and cushions the impact from above by an elastic spring (S1) and / or an additional spring (S2). Therefore, the floor plate (110) using the wooden board (B) is easily leveled and cushions interfloor noise.

[0127] Meanwhile, the wooden building material (100) composed of the aforementioned wooden post (P) and / or wooden board (B) has significantly enhanced rigidity while maintaining lightness since steel pipe reinforcing bars (B) are arranged spaced apart therein as illustrated in FIGS. 10 and 29, and the heat-resistant fabric (40) is attached to the steel pipe reinforcing bars (60), so that the heat resistance is also significantly enhanced, and the heat-resistant fabric (40) is attached by an adhesive received in an adhesive insertion groove (63) of the steel pipe reinforcing bars (60), so that it is firmly attached. In addition, as illustrated in FIGS. 7 and 27, the wooden building material (100) has a part of a screw shaft provided in a headless bolt (71) or a nipple bolt (73) of a male screw member (70) inserted into the steel pipe reinforcing bars (60), so that a part of the inserted screw shaft is supported on the inner surface of the steel pipe reinforcing bars (60). Accordingly, the screw member (70) is stably and firmly fixed to the steel pipe reinforcing bar (60).

[0128] On the other hand, since the steel pipe reinforcing bar (60) is composed of a hollow pipe as shown in FIG. 8 and FIG. 27, it has a wider support area than ordinary reinforcing bars and has a high elastic modulus, so it is not easily bent and deformed, and can support a structure very stably in the event of a fire or earthquake.

[0129] On the other hand, the wooden boards (B) are easily connected through the angle (83) or the channel (85) by being installed on at least both sides of the angle (83) or the channel (85) as illustrated in FIGS. 31 to 35. These wooden boards (B) are substantially supported at their ends by the support bars (89a) by being installed through the bolting plates (83a, 85a) of the angle (83) or the channel (85) as illustrated. Accordingly, a plurality of wooden boards (B) are stably fixed to the angle (83) or the channel (85).

[0130] And, as shown in FIGS. 31 to 32 and 35, the wooden boards (B) are connected by bolting to the bolting plates (83a, 85a) with additional brackets (80a) in the form of a channel or angle, so that the angles (83) or channels (85) installed on the surrounding wooden boards (B) through the additional brackets (80a) are easily assembled as shown.

[0131] On the other hand, the embodiment of the present invention may additionally be provided with a reinforcing flame retardant (90) as illustrated in FIGS. 37 and 38. The reinforcing flame retardant (90) may be composed of, for example, at least one of an additional heat-resistant fabric (91) and / or a wood flame retardant sheet (93) attached to the outer surface of one or both sides of the wood panel (PN) as illustrated. The additional heat-resistant fabric (91) is composed of the aforementioned cerak wool. In addition, the wood flame retardant sheet (93) is composed of a veneer plate having a thickness of about 4 mm to 12 mm that has been flame retardant-treated in the manner described above.

[0132] When the reinforcing flame retardant (90) is composed of an additional heat-resistant fabric (91) and a wood flame-retardant sheet (93) as shown, the additional heat-resistant fabric (91) is attached to the surface of the wood panel (PN) using the aforementioned flame-retardant adhesive, and the wood flame-retardant sheet (93) is attached to the outer surface of the additional heat-resistant fabric (91) using the aforementioned flame-retardant adhesive.

[0133] The reinforcing flame retardant (90) may be composed of only a plurality of wooden flame retardant sheets (93). In this case, the wooden flame retardant sheets (93) are sequentially attached to the outer surface of the wooden panel (PN) using a flame retardant adhesive and overlapped (laminated).

[0134] The reinforcing flame retardant (90) may be configured such that a wood flame retardant sheet (93) is first attached to the outer surface of a wood panel (PN), then an additional heat-resistant fabric (91) is attached, and then the wood flame retardant sheet (93) is again attached to the outer surface of the additional heat-resistant fabric (91). The quantities of the wood flame retardant sheet (93) and the additional heat-resistant fabric (91) are determined according to the required heat-resistant characteristics.

[0135] In the embodiment of the present invention as described above, in the event of a fire, the wood fire-retardant sheet (93) provided on the outermost surface of the wood panel (PN) is preferentially ignited and burned to form a carbonized layer. At this time, the wood fire-retardant sheet (93) forms a carbonized layer of about 0.6 mm per minute to delay the spread of the fire through the carbonized layer. In addition, the additional heat-resistant fabric (91) insulates the transferred heat to further delay the spread of the fire. In addition, when the wood fire-retardant sheet (93) is also provided between the additional heat-resistant fabric (91) and the wood panel (PN), the heat of the fire can be additionally insulated through the wood fire-retardant sheet (93), thereby further delaying the spread of the fire. Therefore, the reinforced fire-retardant material (90) provides multiple fire-resistant layers for the embodiment of the present invention to strengthen its own heat resistance, thereby extending the initial evacuation time or fire suppression time, and further suppressing the generation of toxic gases.

[0136] For reference, the aforementioned wood flame retardant sheet (93), when configured with a thickness of, for example, 6 mm, burns at a rate of about 0.6 mm per minute and carbonizes for about 10 minutes, thus providing a fire delay time of about 10 minutes, i.e., an evacuation time and a fire extinguishing time.

[0137] Meanwhile, when the wooden building material (100) is composed of a plate-shaped wooden board (B) as described above, an additional reinforcing material may be provided to further reinforce the rigidity of the wooden board (B). The additional reinforcing material may include, for example, a fiber-reinforced polymer (95) attached to the outer surface of the wooden board (B) composed of wooden panels (PN) as illustrated in FIGS. 39 and 40, and a shielding plate (97) attached to the outer side of the fiber-reinforced polymer (95).

[0138] Fiber-reinforced polymers (95) are composites in which functional fibers providing strength, durability, corrosion resistance, and light weight are combined with polymers providing heat resistance, chemical resistance, adhesion, strength, and water resistance. In other words, fiber-reinforced polymers (95) are composites composed of a combination of high-performance fibers and reinforced polymers. Such fiber-reinforced polymers (95) are also used as materials for vehicles and airplanes due to their excellent strength and light weight properties.

[0139] The fiber-reinforced polymer (95) is composed of a fiber functional sheet woven with at least one of carbon fiber, glass fiber, or aramid fiber for reinforcing strength, as illustrated in FIGS. 39 and 40, and is typically integrally attached to the outer surface of the wood board (B) by a polymer such as an epoxy resin. In particular, it is preferable that the fiber-reinforced polymer (95) be composed of carbon fiber, which has excellent strength and durability. This fiber-reinforced polymer (95) reinforces the rigidity of the wood board (B) by the fiber functional sheet and polymer described above.

[0140] The shielding plate (97) is attached to the outside of the fiber-reinforced polymer (95) to shield the fiber-reinforced polymer (95), as illustrated in FIGS. 39 and 40. The shielding plate (97) is preferably configured in the same manner as the flame-retardant thin plate (93) described above, for example, to provide a carbon layer on the outside of the fiber-reinforced polymer (95) by preferential ignition in the event of a fire.

[0141] Another embodiment of the present invention configured as described above is a fiber functional sheet of fiber reinforced polymer (95) attached to the outside of a wood board (B) into which a steel pipe reinforcing bar (60) is inserted, as illustrated in FIGS. 39 and 40, by means of a liquid polymer. Then, a shielding plate (97) is attached to the outside of the fiber reinforced polymer (95) of the wood board (B). At this time, the shielding plate (97) may be attached by means of the polymer, or may be attached by means of the flame retardant adhesive described above after the polymer is cured.

[0142] The fiber-reinforced polymer (95) provides rigidity through the fiber functional sheet as the polymer hardens. Accordingly, the wood board (B) is strengthened in strength and rigidity. In particular, the wood board (B) may be provided with the fiber-reinforced polymer (95) on only one side, but as illustrated, when the fiber-reinforced polymer (95) is provided on both sides, the strength and rigidity are doubled. Therefore, whether the wood board (B) is installed vertically or horizontally, the support capacity for the upper load is strengthened by the fiber-reinforced polymer (95) and the shielding plate (97), and the heat resistance against fire is also strengthened.

[0143] Another embodiment of the present invention, as described above, is applicable to high-rise buildings because the strength and rigidity of the wooden board (B) are primarily reinforced by the steel pipe reinforcing bar (60) and secondarily reinforced by the fiber-reinforced polymer (95). In addition, the steel pipe reinforcing bar (60) and the fiber-reinforced polymer (95) attached to the wooden board (B) with the heat-resistant fabric (40) wound or attached thereto enhance the heat resistance of the wooden board (B), thereby further delaying the spread of fire.
