[0024] Referring to the drawings, the present invention includes, as main components, a primary insulation material (110), a lumber (120), and a secondary insulation material (130) on a ceiling OBS plywood (100) installed on a ceiling slab (SLV), a lumber (120) on the secondary insulation material (130), a roof plywood (140), and a waterproofing layer (150).

[0025] Meanwhile, in the present invention, the primary insulation material (110) and the secondary insulation material (130) are both bead insulation boards, and it is stated in advance that the primary insulation material (110) and the secondary insulation material (130) described below are bead insulation boards.

[0026] The above primary insulation material (110) is configured in the shape of a square plate. At this time, the above primary insulation material (110) is configured in the shape of a square plate having a short side portion that is relatively shorter in length and a long side portion that is relatively longer in length. The above primary insulation material (110) is configured in the shape of a square plate having two long side portions parallel in the length direction and two short side portions parallel in the width direction. In the present invention, the length of the long side portion in the length direction of the primary insulation material (110) is 1800mm, and the length of the short side portion in the width direction is 900mm. Of course, it is obvious that the length of the long side portion and the length of the short side portion of the primary insulation material (110) may vary.

[0027] At this time, the primary insulation material (110) is formed into a plate shape by binding a large amount of EPS beads with a binder, so the primary insulation material (110) becomes a bead method insulation board.

[0028] A timber joining groove (112) for joining timbers (120) is formed in the primary insulation material (110). The timber joining groove (112) extends in a direction parallel to the long side of the primary insulation material (110). At least two timber joining grooves (112) are formed in the primary insulation material (110). That is, the timber joining groove (112) is formed along the length direction of the primary insulation material (110), and at least two timber joining grooves (112) are formed in the left-right width direction of the primary insulation material (110). In the present invention, it is illustrated that two are formed in the left-right width direction of the primary insulation material (110). That is, the above-mentioned timber joint groove (112) extends in a direction parallel to the long side of the primary insulation material (110), and the above-mentioned timber joint groove (112) is formed in at least two places in the primary insulation material (110).

[0029] The above-mentioned square timber (120) is configured in a square bar shape. The above-mentioned square timber (120) is configured in a square bar shape made of wood material. The square timber coupling groove (112) of the above-mentioned primary insulation material (110) is configured in a square groove shape, so that the square bar-shaped square timber (120) is seated and coupled in the square groove-shaped square timber coupling groove (112) of the above-mentioned primary insulation material (110). That is, the above-mentioned square timber (120) is configured in a square bar shape, and the square timber coupling groove (112) of the above-mentioned primary insulation material (110) is configured in a square groove shape, so that the square bar-shaped square timber (120) is seated and coupled in the square groove-shaped square timber coupling groove (112).

[0030] In the present invention, the ceiling OSB plywood and the roof insulation are fixed to the primary insulation (110) using screw bolts (SBT) that can fix them to each other. That is, the ceiling OSB plywood (100) and the primary insulation (110) are fixed to the lumber (120) using screw bolts (SBT).

[0031] With multiple primary insulation materials (110) laid out in a grid pattern on the ceiling OBS plywood (100) installed on the ceiling slab, the timber (120) is seated and joined in the timber joining grooves (112) of the multiple primary insulation materials (110), thereby increasing the installation strength of the primary insulation layer (110) formed by laying out multiple primary insulation materials (110) and preventing the position of the multiple primary insulation materials (110) from shifting. That is, the timber (120) is inserted into the timber joining grooves (112) of the primary insulation materials (110) and structurally connected to the roof OSB plywood, thereby reinforcing the rigidity of the roof structure. The term "roof structure" refers to a roof insulation structure comprising a primary insulation material (110), a lumber (120), a secondary insulation material (130), another lumber (120) on top of the secondary insulation material (130), a roof-side plywood, and a waterproofing layer (150), which are the main parts of the present invention.

[0032] The above secondary insulation material (130) is configured in the shape of a square plate. At this time, the above secondary insulation material (130) is configured in the shape of a square plate having a short side portion that is relatively shorter in length and a long side portion that is relatively longer in length. The above secondary insulation material (130) is configured in the shape of a square plate having two long side portions parallel in the length direction and two short side portions parallel in the width direction. In the present invention, the length of the long side portion in the length direction of the secondary insulation material (130) is 1800mm, and the length of the short side portion in the width direction is 900mm. Of course, it is obvious that the length of the long side portion and the length of the short side portion of the secondary insulation material (130) may vary.

[0033] At this time, the secondary insulation material (130) is formed into a plate shape by binding a large amount of EPS beads with a binder, so the secondary insulation material (130) becomes a bead method insulation board.

[0034] Meanwhile, the above secondary insulation material (130) is a bead method type 2 insulation material that combines insulation and thermal bridge blocking.

[0035] The above secondary insulation material (130), which is a bead method type 2 insulation material for insulation and thermal bridge blocking, is additionally installed in an intersecting manner on the upper part of the above primary insulation material (110) (primary bead method insulation material for roofing).

[0036] At this time, the additional installation of the secondary insulation material (130) in a direction that intersects the primary insulation material (110) means that the left and right width direction of the short side of the primary insulation material (110) and the length direction of the long side of the secondary insulation material (130) are installed in a direction that is perpendicular to each other.

[0037] In other words, the first insulation material (110) and the second insulation material (130) are in the shape of a square plate having a relatively shorter side and a relatively longer side, and the long side of the second insulation material (130) is arranged in a direction perpendicular to the short side of the first insulation material (110), while the short side of the second insulation material (130) is arranged in a direction perpendicular to the long side of the first insulation material (110).

[0038] The above secondary insulation material (130) is placed crosswise over the above primary insulation material (110) to form an additional insulation layer, thereby completely blocking thermal bridges.

[0039] A square timber (120) is placed on top of the secondary insulation material (130) and installed. The square timber (120) installed on the secondary insulation material (130) is a different square timber (120) from the square timber (120) that is seated and joined in the square timber joining groove (112) of the primary insulation material (110).

[0040] The square timber (120) installed on the secondary insulation material (130) is also configured in a square bar shape. The square timber (120) is configured in a square bar shape made of wood material.

[0041] Multiple timbers (120) are cut to size and installed on the secondary insulation material (130) at regular intervals. Multiple timbers (120) can be installed in a grid pattern on the secondary insulation material (130).

[0042] A plurality of timbers (120) installed on the secondary insulation material (130) serve as spacers to form a roof ventilation layer (143) between the bottom surface of the roof plywood (140) installed on top and the top surface of the secondary insulation material (130).

[0043] In the present invention, the secondary insulation material (130) and the square timber (120) can be combined with a fastener such as a screw bolt (SBT) to stably fix the square timber (120) on the secondary insulation material (130).

[0044] By installing a plurality of secondary insulation materials (130) formed in the shape of square plates on a primary insulation layer formed by installing a plurality of primary insulation materials (110), a secondary insulation layer can be formed on the primary insulation layer, and the square member (120) can be installed on the secondary insulation layer.

[0045] The roof plywood (140) is joined by being placed on the lumber (120). The roof plywood (140) is placed on top of the secondary insulation material (130). The roof plywood (140) is an OSB plywood and is installed on top of the secondary insulation material (130) by being fastened to the lumber (120) with screw bolts (SBT) while being placed on top of the lumber (120) installed on the secondary insulation material (130). That is, the structure is such that a roof plywood layer (140) in which a plurality of roof plywoods (140) are arranged in a grid pattern is placed on top of a secondary insulation layer formed by a plurality of secondary insulation materials (130) arranged in a grid pattern.

[0046] The above roof plywood (140) is fixed to the above lumber (120), and a roof ventilation layer (143) is formed between the roof plywood (140) and the secondary insulation material (130). That is, the roof plywood (140) is installed by being placed on the lumber (120) installed on the secondary insulation material (130), thereby forming a roof ventilation layer (143) between the bottom surface of the roof plywood (140) and the top surface of the secondary insulation material (130). In other words, a roof ventilation layer (143) is formed in a space spaced apart by a certain angle between the bottom surface of the roof plywood (140) layer formed by arranging multiple roof plywoods (140) and the top surface of the secondary insulation layer formed by arranging multiple secondary insulation materials (130).

[0047] In addition, the present invention includes a waterproof layer (150) installed on the roof plywood (140). The waterproof layer (150) may be installed by attaching a waterproof sheet to the roof plywood (140) using a bonding means such as an adhesive. The waterproof layer (150) is composed of multiple waterproof sheets (150WS) installed on the roof plywood (140), and the waterproof sheets (150WS) enhance the prevention of leakage. That is, the waterproof sheets (150WS) are installed in a grid pattern on the roof plywood (140) to form a waterproof layer (150) and enhance the prevention of leakage.

[0048] Meanwhile, the present invention is a method for constructing double insulation for blocking roof thermal bridges, comprising: step 1, installing a primary insulation material (110) (bead method insulation board type 2 insulation material) having a square member connection groove (112) formed after installing a ceiling OBS plywood (100) on a roof slab of a building; step 2, cutting a square member (120) to a certain length to be connected to the square member connection groove (112) of the primary insulation material (110); step 3, inserting and fixing the cut square member (120) into the square member connection groove (112) of the primary insulation material (110); step 4, fixing the primary insulation material (110) and the square member (120) by means of a fastener; and adding a secondary insulation material (130) (bead method type 2 insulation material) for both insulation and thermal bridge blocking on the primary insulation material (110). The method includes step 5, which involves additionally installing the secondary insulation material (130) in a direction that intersects the primary insulation material (110); step 6, which involves additionally installing a plurality of timbers (120) at regular intervals on the secondary insulation material (130); and step 7, which involves cutting a roof plywood (140) (roof OSB plywood) and fixing it to the plurality of timbers (120) arranged at regular intervals on the lower secondary insulation material (130) so that a roof ventilation layer (143) is formed between the roof plywood (140) and the secondary insulation material (130).

[0049] In addition, the present invention further includes step 8 of installing a roof-specific waterproof sheet (150WS) on the roof plywood (140).

[0050] The method for constructing a double insulation material to block roof thermal bridges according to the present invention is primarily a method for constructing a double insulation material to block roof thermal bridges in steel frame structures, and the method for constructing a double insulation material to block roof thermal bridges in steel frame structures will be explained below.

[0052] Step 1. After installing the OSB plywood for the ceiling, a grooved bead insulation board of type 2 is installed as a first layer. That is, the first layer of insulation (110) is installed in a grid pattern on the upper part of the roof slab to form a first layer of insulation.

[0053] Step 2. Cut a 38mm square timber (120) to the length of the Type 2 bead insulation board with grooves at regular intervals.

[0054] Step 3. A 38mm square timber (120) is inserted and fixed into the Type 2 bead insulation board with grooves formed at regular intervals. That is, a 38mm square timber (120) is inserted and fixed into the square timber joining groove (112) of the primary insulation board (110).

[0055] Step 4. The ceiling OSB plywood and the roof insulation are secured to the 38mm square timber (120) of the primary bead insulation using screw bolts (SBT) that can secure the ceiling OSB plywood and the roof insulation to each other. That is, the ceiling OSB plywood, the primary insulation (110), and the square timber (120) are secured to each other using screw bolts (SBT).

[0056] Step 5. Additional insulation material of the bead method (i.e., secondary insulation material (130)) for insulation and thermal bridge blocking is installed in an intersecting manner on the upper surface of the primary insulation material (110) (i.e., the upper surface of the primary insulation material (110)). Multiple secondary insulation materials (130) are installed in a grid pattern on the upper surface of the first insulation layer, and by installing multiple secondary insulation materials (130) in a direction intersecting with multiple primary insulation materials (110), a second insulation layer and a roof ventilation layer (143) are formed.

[0057] Step 6. To fix the additionally constructed secondary insulation (130) (bead method type 2 insulation) and roof plywood (140) (i.e., roof OSB plywood), 38mm square timbers (120) are cut to size and installed at regular intervals.

[0058] Step 7. After cutting the roof plywood (140) (i.e., roof OSB plywood), fix it to the lower 38mm square timber (120) to create a roof ventilation layer (143).

[0059] Step 8. A roof-specific waterproof sheet (150WS) is installed on the roof OSB plywood. That is, a waterproof sheet (150WS) is installed on the upper surface of the roof plywood (140) to form a roof waterproof layer (150).

[0060] Accordingly, the present invention forms a double insulation layer using EPS (bead insulation board) insulation material and reinforcing timber (120) to block thermal bridges occurring in the roof section, and implements a roof insulation structure with an improved bonding structure between the roof material and OSB plywood, thereby enabling sufficient insulation effect of the roof section due to the blocking of thermal bridges in the roof section.

[0061] In addition, the present invention has a roof ventilation layer (143) formed between the bottom surface of the roof plywood (140) and the top surface of the secondary insulation material (130) due to a plurality of timbers (120) installed on the secondary insulation material (130), so that smooth ventilation of the roof portion is achieved through the roof ventilation layer (143), and the phenomenon of moisture accumulating in the roof insulation material is prevented, thereby maintaining a comfortable indoor environment.

[0062] In addition, the present invention forms a roof ventilation layer (143) between the bottom surface of the roof plywood (140) and the top surface of the secondary insulation material (130), thereby further increasing the insulation efficiency of the roof portion. Without the roof ventilation layer (143), there is a possibility that the insulation efficiency would be undesirable, but the roof ventilation layer (143) has the effect of sufficiently increasing the insulation efficiency.

[0063] Meanwhile, FIG. 19 is a side view schematically showing the structure of the connection part between the primary insulation material and the lumber, which is the main part of the roof thermal bridge blocking double insulation construction structure according to another embodiment of the present invention; FIG. 20 is an enlarged view of the main part of FIG. 19; FIG. 21 is a cross-sectional view showing a part of the roof thermal bridge blocking double insulation construction structure according to yet another embodiment of the present invention; FIG. 22 is an enlarged view of the main part of FIG. 21; FIG. 23 is a cross-sectional view showing a part of the connection structure of the primary insulation material, the core reinforcing channel member, and the screw bolt, which is the main part of the roof thermal bridge blocking double insulation construction structure according to yet another embodiment of the present invention; FIG. 24 is an enlarged view of the main part of FIG. 23; and FIG. 25 is a cross-sectional view showing a part of the connection structure of the primary insulation material, the core reinforcing channel member, and the screw bolt, which is the main part of the roof thermal bridge blocking double insulation construction structure according to yet another embodiment of the present invention.

[0064] Referring to the drawing, the present invention further includes a plurality of bottom protrusions (162) extending in the longitudinal direction at the bottom portion of the square member joining groove (112) of the primary insulation material (110).

[0065] According to the present invention, when a piece of wood (120) is inserted into the piece of wood joining groove (112) of the primary insulation material (110), the bottom protrusion (162) supports the piece of wood (120) from below, thereby securing a space of a certain distance between the bottom surface of the piece of wood (120) and the bottom part of the piece of wood joining groove (112).

[0069] The upper cushioning stone and the lower cushioning stone are positioned in an offset position, so that the upper cushioning stone (173) contacts the inner surface of the lower plate (175) of the filling insulation plate (170) to provide cushioning, and the lower cushioning stone (176) contacts the inner surface of the upper plate (172) of the filling insulation plate (170) to provide cushioning, so that the filling insulation plate (170) has the effect of preventing noise generation and shock caused by cushioning between the first insulation layer and the second insulation layer.

[0070] Meanwhile, a plurality of spacing protrusions (178) are provided on the upper surface of the upper plate portion (172) of the above-mentioned filling insulation plate (170) and on the lower surface of the lower plate portion (175), and a roof ventilation layer (143) for ventilation is secured between the upper surface of the upper plate portion (172) of the above-mentioned filling insulation plate (170) and the lower surface of the roof plywood (140) by the spacing protrusions (178), and a roof ventilation layer (143) is also secured between the lower surface of the lower plate portion (175) of the above-mentioned filling insulation plate (170) and the upper surface of the secondary insulation material (130).

[0071] Therefore, it is possible to ensure smooth ventilation between the above-mentioned filling insulation board (170), the above-mentioned roof plywood (140), and the secondary insulation material (130).

[0072] In addition, in the present invention, a core reinforcing channel member (182) made of metal material is further provided inside the primary insulation material (110), and the core reinforcing channel member (182) is provided with a bolt connection boss (184) protruding upward, and a screw bolt (SBT) connected in the square member (120) passes through the square member connection groove (112) of the primary insulation material (110) and the threaded portion of the outer surface of the screw bolt (SBT) is connected to the threaded portion of the inner surface of the bolt connection boss (184), and the threaded portion of the lower outer surface of the screw bolt is connected to the ceiling OBS plywood (100) laid on the roof slab.

[0073] Accordingly, by reinforcing the strength of the primary insulation material (110) with the internal core reinforcing channel member (182), the strength of the primary insulation material (110) is reinforced, and by reinforcing the strength of the primary insulation material (110), the strength of the roof insulation structure constructed on the roof slab of the building is further increased. Additionally, since the screw bolt (SBT) is screw-type connected to the bolt connection boss (184) of the core reinforcing channel member (182), the strength of the roof insulation structure constructed on the roof slab of the building is further increased.

[0074] In addition, the present invention is provided with channel-side wing portions (186) protruding from both sides of the core reinforcing channel member (182), and the channel-side wing portions (186) support the core reinforcing channel member (182) so that it is more firmly installed inside the primary insulation material (110). Since the channel-side wing portions (186) triple-support the core reinforcing channel member (182) that reinforces the primary insulation material (110) itself from the inside and the primary insulation material (110), the strength of the roof-side insulation structure constructed on the roof slab of a building is increased to the maximum.
