Insulation standards for building structures are regulated as “energy saving design standards for buildings” due to global warming and resource depletion.

In particular, the walls and slabs facing the outside are required to install insulation,

The prior art for the lowest floor slab,

 1 (a) heat-resistant insulation method for installing the heat insulating material (I) in the upper part (inside the living room) of the slab (S),

Although there is an external insulation method installed in the lower portion of the slab (S) of Figure 1 (b),

Since the heat-resistant method must be reinforced with pressed mortar (M) on the heat insulating material (I) to prevent settlement by the heat insulating material (I), the external heat insulating method is generally preferred.

Originally, the external insulation method is applied to a piloti building in which the lowest floor of the building is two or more floors,

It is often applied to the mat foundation MF that faces the ground and supports the load of the building as shown in FIG. In other words, the insulating material (I) is provided between the discarded concrete (IC) and the mat foundation (MF) for leveling the ground surface on the ground (G) that supports the load of the building.

In the case of Figure 1 (c), the contradiction occurs to support the building by the compressive strength of the heat insulating material (I) having no structural performance.

In general, the insulation is a structure containing air to insulate the air over time, it is vulnerable to long-term compressive load and sinking occurs, so that the load of the building facing the ground (G) as shown in Figure 1 (c). Supporting mat foundations is a major problem for building safety in the long term.

Even in the urethane foam insulation, which is the most effective among the long-term compressive loads, the long-term compressive load test of 40 KPa at a density of 33 kg / m 3 yields 1.9% of creep, and 20-30 KPa in consideration of deformation (settlement) and safety. It is the limit to support the building of the one-story building because the bearing capacity of is applicable.

The present inventors do not have a comprehension and lack of alternatives to the above problems, the wrong method as shown in Fig. 1 (c) is continuously applied to the existing cost and convenience of the building for the cost and convenience, there is a problem in the safety of the building, the present invention as a solution It came to the following.

Vertical compression stiffener insertion type hybrid insulation board (IB) of the present invention,

Thermal insulation material 200 is installed horizontally;

Reinforcement 100 is installed in a plurality of vertically arranged on the same level in the heat insulating material 200;

Consists of including

The upper and lower ends of the reinforcing material 100 coincide with the upper and lower ends of the heat insulator 200, and the load acting on the upper part corresponds to the reinforcing material 100.

4 is a detailed view of the reinforcing material used in the present invention.

The reinforcing material 100,

The upper plate 110a and the lower plate 110b are formed at the upper and lower portions, respectively.

Between the upper plate 110a and the lower plate 110b is characterized in that the pillar 120 is installed,

The pillar 120 includes a central core pillar 121; and a plurality of wing pillars 122 vertically installed on an outer circumferential surface of the core pillar 121.

That is, the projection area is formed to have a wider surface area compared to the cross-sectional area while preventing buckling easily occurring in the elongated member and considering the integrity with the heat insulating material 200.

The cross section of the core pillar 121 is preferably circular, but may be a polygon of three or more triangles, and the cross section of the wing pillar 122 may be a polygon or a triangle or more that is thickened toward the core pillar 121.

And on the lower portion of the upper plate 110a and the upper portion of the lower plate 110b,

Reinforcement unit 130 for reinforcing the connection portion with the pillar 120;

Characterized in that is formed.

The reinforcement part 130 serves to prevent breakage by dispersing stress concentrations at the top and bottom of the pillar.

The reinforcing member 100, a positioning hole (H) penetrating from the upper center to the lower center; may be formed.

The positioning hole (H) is a space that can be inserted into a separate equipment to the vertical compression stiffener insertion type hybrid insulation plate (IB) of the present invention when the position of the reinforcement is selected and mounted and the insulation 200 foamed when the It serves to prevent fluctuation of reinforcement position.

Since the reinforcement 100 is only responsible for the structural performance with a small cross-sectional area, there is little or negligible heating bridge and cooling bridge phenomena due to the reinforcement.

If the reinforcement 100 is secured, any material such as steel, non-ferrous materials can be used, and particularly, if the non-ferrous material having a low heat transmission rate is used, the thermal insulation performance will be increased.

 In other words, the reinforcement 100 is a material that is easy to form and maintains shape and material properties without corrosion even for a long time, and suitable for metal or plastic materials, such as aluminum, plastic is considered to be durable PVC, PVC ( Polyvinyl chloride) series is preferable.

The insulating material 200 can be any material that can insulate, but in consideration of thermal insulation performance, formability, compressive strength, long-term deformation, etc., rigid polyurethane foam and expanded polystyrene (EPS) are desirable.

Therefore, the horizontal compression reinforcement insert-type hybrid insulation plate (IB) of the present invention may be manufactured in a factory and installed dry on the site,

Depending on the site circumstances, the heat insulating material 200 may be foamed and cured after the reinforcement 100 is installed.

In addition, attaching or installing a waterproof sheet to the upper or upper surface of the insulation 200 prevents corrosion of the upper reinforcement 110 and the lower reinforcement 120, and the insulation 200 is a liquid concrete It is effective because it can prevent the sinking.

5 is a conceptual diagram of a basic structure using a hybrid compression plate inserted vertical compression stiffener of the present invention.

The basic structure using the vertical compression reinforcement insert type hybrid insulation board of the present invention,

The vertical compression stiffener inserted hybrid hybrid insulation plate (IB),

Ground (G);

Discarded concrete (IC) installed on the ground (G);

The vertical compression reinforcement insert-type hybrid insulation plate (IB) disposed on the discarded concrete (IC);

A mat foundation (MF) installed on the vertical compression reinforcement insert-type hybrid insulation board (IB);

Consists of including

Since the load of the building structure is transmitted downward through the mat base MF and the reinforcement 100 in order, the heat insulating material 200 is characterized in that the load is released from the load sharing.

In other words, if the cast concrete (IC) is laid on the ground (G) with a bearing capacity, and the insulation board (IB) of the present invention is installed on the top and the mat foundation (MF) is constructed, the building load is Dispersed in a mat base (MF) is transferred from the heat insulating plate (IB) in the order of the reinforcing material 100 of the pedestal 100, it is finally supported on the ground (G) through the discarded concrete (IC) of the lower It is done.

At this time, the surface of the heat insulator 200 is to include a waterproof waterproof sheet is effective to prevent the heat insulator 200 is submerged in the liquid concrete.

The compressive strength of the vertical compressive reinforcement insert-type hybrid insulation board (IB) of the present invention with respect to the building load is the strength of the reinforcement 100 and the placement interval (number per square meter), the stress that is in contact with the insulation board (IB) is transmitted The history of the mat foundation (MF) and the discarded concrete (IC) is a parameter,

The strength of the reinforcement 100 is determined by the cross-sectional area of the column 120 considering the material strength and the buckling, and the strength of the mat foundation MF and the discarded concrete IC is determined by the compressive strength of the concrete and the mat foundation ( MF) and the ground area of the disks 110a and 110b in contact with the discarded concrete IC.

In addition, if the ground area of the upper plate (110a) and the lower plate (110b) is the same so that there is no distinction between the top and bottom of the pedestal 100 for the convenience of production and operation, generally the mat foundation (MF) is the discarded concrete Since the compressive strength is higher than that of (IC), the ground area of the upper and lower plates 110a and 110b is determined as the concrete compressive strength of the discarded concrete (IC).

For example, the required bearing capacity is 200 kN / ㎡, the spacing of the reinforcement 100 in the vertical compressive reinforcement insert-type hybrid insulation board (IB) is 200 mm (25ea / ㎡), respectively, in both directions of the reinforcement 100 Material strength is 60N / mm2 (applied to 40.2N / mm2, which is 0.67 (= 1 / 1.5) times considering long-term stability), and concrete compressive strength of cast concrete (18) is 18N / mm2 (0.3 times considering long-term stability) N / mm2), the support pillar 120 is assumed to be buckled by the blade 122, the radius of the core pillar 121 is 6mm, the wing pillar 122 is' + If you make four in the form and the thickness to 3 mm,

1 required load capacity of the pedestal 100 of the bone = 200kN / ㎡ ÷ 25ea = 8kN

Ground area of the upper and lower plates 110a and 110b = 8 kN ÷ 5.4 N / mm 2 ≒ 1,481 mm 2

Radius of the upper and lower plates 110a and 110b = √ (1,481 / π) ≒ 21.72 mm

Possible proof strength of the core pillar 121 = 40.2 N / mm 2 × π 6 mm × 6 mm ≒ 4.54 kN

1 load capacity of the wing pillar 122 of the bone = (8kN-4.54kN) ÷ 4 ≒ 865N

Required length of the wing post 122 = 865 N ÷ 40.2 N / mm 2 ÷ 3 mm ≒ 7.17 mm

in,

In the reinforcement 100, the radii of the upper and lower plates 110a and 110b are 22 mm, the radii of the core pillar 121 are 6 mm, and the wings 122 are four in the form of '+' and the thickness is 3 mm. , 7.5mm in length,

When the arrangement interval of the reinforcement 100 in the vertical compression reinforcement insert-type hybrid insulation board (IB) is 200 mm (25ea / m 2) in both directions, the insulation board (IB) can cope with bearing strength of 200 kN / m 2 or more. Therefore, it can be used safely in a building of about five stories.

On the other hand, the cross section (A) occupied per square meter of the core pillar 121 penetrating the heat insulating material 200 is

A = 25ea × (π × 6 mm × 6 mm + 4 × 3 mm × 7.5 mm) = 5,076 mm2

Since, as much as 0.5% in the heat insulating material 200 of 1㎡, the influence of the heating bridge (heating bridge) by the core pillar 121 is negligible and negligible.

Although the present invention has been described in connection with the preferred embodiment as mentioned above, various modifications and variations are possible without departing from the gist of the present invention, and can be used in various fields.

Therefore, the claims of the present invention include modifications and variations that fall within the true scope of the invention.
