Thermal bridge refers to a part where thermal insulation is not continuous at a connection part of a building structure and this part becomes a thermally weak part and a lot of heat and energy is lost to the outside. The energy loss occurs in the building due to the occurrence of thermal bridges, and the area where the thermal bridges occur causes the surface temperature to become low, causing condensation, thereby damaging the interior material of the building, thereby degrading the value of the building.

Thermal break is to prevent the thermal bridge phenomenon. It is designed to prevent the insulation bridge from being discontinuous at the site where heat bridging occurs, So that the thermal bridge is blocked.

By blocking the indoor and outdoor thermal bridges, it is possible to reduce the indoor heating energy by improving the heat insulation effect, and thus the CO ₂ generation amount can be reduced. In addition, it is possible to suppress the occurrence of condensation and mold caused by the thermal bridging phenomenon, thereby improving the quality of the indoor air. Of course, it is possible to maintain the value of the structure by preventing damaging of the interior material caused by condensation. .

Thermal bridges are often found in areas where the structure of a building changes and where materials change. Particularly, in the case of balconies, structural bridges and material bridge bridges all occur. Since it accounts for 15 ~ 30% of the total heat bridging phenomenon of the building, it is necessary to shut off the bridging of the balcony in order to prevent the heat bridging.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

Fig. 1 is a perspective view of a buried type bridge bridge having a front end partition according to the present invention, and Fig. 2 is a sectional view.

The buried type bridge bridge device having a front end partition according to the present invention includes a heat insulation block 20 disposed between upper and lower compression modules 10 and 10a and upper and lower compression modules 10 and 10a, And a shear root 40 inserted into the heat insulating block 20. The sheath 40 is inserted into the heat insulating block 20,

The upper and lower compression modules 10 and 10a are constructed in the same manner and are symmetric with respect to each other so as to face each other.

The compression module 10 includes a plate-like compression plate 11, compression protrusions 12 vertically protruding upward at regular intervals in the longitudinal direction on the upper surface of the compression plate 11, And a front end partition plate 13 extending downward.

The compression protrusions 12 of the compression module are formed so as to form the reinforcement grooves 14 between the compression protrusions 12 and 12 adjacent to each other so that the slab reinforcement is continuously laid from the building body to the balcony side in the reinforcement grooves 14. [ The spacing of the compression protrusions 12 is determined in consideration of the slab reinforcement.

The slab reinforcement is laid on the balcony 14 side from the building body without cutting or separate joint. Therefore, since it is not necessary to change the method of reinforcing steel reinforcement, work time is shortened and installation is easy, and structural stability is ensured because the slab reinforcement is resistant to the bending moment acting on the balcony. The embedding type bridge bridge having a front end partition according to the present invention is embedded in a concrete slab, and the protruding length of the compression protrusion 12 is determined according to the thickness of the slab reinforcement.

The front end partition plates 13 of the compression modules are formed such that the front end partition plates 13 and 13 of the upper and lower compression modules are coupled to each other to form partition walls at regular intervals in the longitudinal direction of the thermal bridge device, It is a means to increase the resistance. The formation interval of the front end partition plates 13 is determined by the length of the heat insulating block 20. [

The compression module 10 is composed of a material having a predetermined insulation performance and a sufficient compression force. For example, fiber-reinforced concrete, which is a composite material reinforced with various fibers such as chemical fiber or glass fiber, can be constructed. There are various types of fiber reinforced concrete such as ECC, SIFCON, SIMCON and Ductal. The compression module 10 can be composed of this kind of fiber reinforced concrete, and most preferably it is made of ECC (Engineered Cementitious Composite) You can increase your strength and strength. For reference, the compressive strength of ECC is 70 MPa, which is similar to that of high strength concrete.

Conventional devices made of low thermal conductivity materials to block heat bridges often do not exhibit sufficient compressive strength and thus have a problem of shear performance at the building and balcony connection sites.

In the heat bridge breaking device according to the present invention, the compression module is constructed to ensure a sufficient strength. In particular, since the front end partition plates are formed as barrier ribs perpendicularly at regular intervals to resist the vertical load acting on the balcony with shear force, There is also a useful effect with structural stability against cyclic loading.

The height of the front end partition plate 13 of the compression module can be differently formed depending on the height of the heat insulation block 20, the thickness of the slab installed, and the combination of the front end partition plates 13 and 13 of the upper and lower compression modules, 13) An adhesive such as an epoxy may be used for the end portion, and various known methods may be used.

A heat insulating block 20 is formed in a space surrounded by the compression plate 11 and the front end partition 13 of the upper and lower compression modules. The heat insulating block 20 may be a fiber-based or bubble-based material having a general heat insulating function such as a rock surface and expanded polystyrene. The heat insulating block 20 is preferably formed in a rectangular parallelepiped shape and has a lower compression module 10a, a heat insulating block 20, And the compression module 10 in this order.

A dowel bar (30) is embedded in the compression plate (11) of the compression module (10).

The dowel bar 30 is a kind of tensile reinforcing steel which is configured to penetrate the compression plate 11 in the width direction. The dowel bar 30 is formed of stainless steel having the lowest thermal conductivity among metals. Even if the heat bridging is blocked by the heat insulating block 20, when the dowel bar 30 is formed of a reinforcing bar, the high heat conductivity The dowel bar 30 is formed of stainless steel having the lowest thermal conductivity in the metal.

The dowel bar 30 includes a buried reinforcing bar 31 which is horizontally embedded in the compression plate 11 at regular intervals in the longitudinal direction of the compression module so that both ends thereof protrude from the compression plate 11. [ The vertical reinforcing bars 32 extending vertically from one end of the embedded reinforcing bars 31 and the reinforcing bars 32 extending from the extended ends of the vertical reinforcing bars 31 in the same direction as the embedded reinforcing bars 31, And the horizontal reinforcement 33 extending in parallel with the upper and lower compression modules 10 and 31. The dowel bars 30 and 30 embedded in the upper and lower compression modules 10 and 10a can be formed into a cross section.

The buried bridge bridge 30 having a front end partition according to the present invention is installed in a building main body and a balcony connection part, and the dowel bar 30 constituting a closed end is integrally joined with the balcony side concrete and the building main body side concrete And is a means for realizing the dowel action by restricting the concrete on the balcony side and the concrete on the side of the building body. That is, after a buried bridge bridging device having a front end partition according to the present invention is installed on the building main body and the balcony connection part, concrete is put into the dowel bar 30 protruded from the compression module 10 to the balcony side and the building main body side, The thermal bridge interrupter is integrated with the balcony-side concrete and the building-side concrete, and the balcony-side concrete and the building-side concrete are effectively confined to the closed type by the dowel bars 30 constituting the closed cross-section.

At this time, the longitudinal roots (50) arranged in the longitudinal direction can be joined to the bent portions of the dowel bars (30). The longitudinal roots 50 are configured to be orthogonal to the direction in which the dowel bars 30 are formed so that the dowel bars 30 and the longitudinal roots 50 are three-dimensionally engaged and constrained to each other to prevent buckling of the members.

And the shear rope 40 is inserted into the heat insulating block 20. The shear reinforcement 40 may be formed of stainless steel as in the case of the dowel bars 30 and is a kind of shear reinforcement that is configured to penetrate the heat insulating block 20 with an inclination in the width direction. The shear root 40 includes an inclined portion 41 intersecting with the X-shaped cross section and embedded in the heat insulating block 20, an inclined portion 41 extending horizontally at both ends of the inclined portion 41, (42).

The formation of the shear root 40 in the form of an X-shape is achieved in the form of a strut-tie so as to realize a truss-closed triangular structure with respect to the shear force, and is designed to have a shear resistance against a vertical load such as a balcony will be.
