BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain wall, and more particularly, to a curtain wall capable of improving heat insulating performance.

In order to dim the natural light, the exterior wall of the building is often constructed with a curtain wall. The curtain wall means a non-load wall that does not support a load when the exterior of the building is closed. The curtain wall makes it possible to attach and detach a finishing material such as glass installed on an outer wall of a building structure. The curtain wall may be made of aluminum and steel as a frame material. The above-mentioned curtain wall has become more interested in industry as the building becomes higher and larger.

The main finishing materials for curtain walls are glass members commonly used for solar shielding, interception, regulation and mining of the external environment. These finishing materials are very sensitive to the control of the indoor environment of buildings.

In addition, recent trends such as high - rise buildings and curtain wall construction applications are very disadvantageous in terms of energy saving. That is, since the heat insulating effect is lower than that of the bearing wall, a large amount of heat loss occurs during heating and cooling. Therefore, various researches are actively carried out to realize a low energy consumption type building, and related industries are interested in developing energy saving type curtain wall products.

The inventor of the present invention has studied a method for improving the heat insulating performance of a curtain wall, and developed various methods for analyzing various factors that deteriorate the heat insulating performance and solving the problems.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. It will be understood by those skilled in the art that the present invention may be embodied in many other specific forms without departing from the spirit or essential characteristics thereof. On the other hand, in the following description, it will be described based on insulation that the cold air flows into the room in winter, but it is also understood that it is used to block the inflow of heat into the room in summer. Also, even in the case where the drawings are different, the same reference numerals are given to parts that perform the same function in the same configuration, so that the ideas of the invention can be easily understood.

The inventor of the present invention has confirmed that there are the following kinds of factors causing deterioration of the heat insulating performance. A heat loss due to insufficient heat insulation performance of a visual opening member such as a glass member supported by a first frame, a heat loss due to heat transfer between inside and outside frames forming a skeleton of a curtain wall, The heat loss due to the inflow of outside air on the connection part, and the inflow of the external liquid on the fourth openable structure and the interframe connection supporting it.

On the other hand, in order to solve the first problem, the inventors attempted to provide a glass member by stacking three layers of glass. However, when three layers of glass members are overlapped, the self-load of the glass member greatly increases, so that various members can not support the glass member, and when the glass member is damaged or deformed for a long time, the frame is totally distorted. In order to solve these problems, the inventor has conducted additional research and development, and proposed a solution to the problem.

1 is a cross-sectional view of a connecting portion of a curtain wall according to an embodiment, showing between a fixing member and a moving member.

Referring to Fig. 1, the fixing member 1 constitutes a stationary portion in the curtain wall, and the moving member 2 indicates a member moving in a certain direction such as a door.

The fixing member 1 is provided with an inner frame 11 which mainly supports a load and is provided in a substantially rectangular cross section, a central heat insulator 20 fastened to the inner frame 11, An outer frame 23 is provided. The inner frame and the central heat insulating material are fastened by a fastening member 4, and the bracket 10 is fastened by the fastening member 4. The bracket 10 is for fastening between the inner frames, and the inner frame in the horizontal direction shown in FIG. 1 and the vertical frame in the vertical direction fastened to the horizontal inner frame are fastened to each other. The central insulator (20) and the outer frame (23) are fastened to each other by a fixing shaft (21). At this time, the fastening stability between the inner frame and the central heat insulating material can be further improved by fastening the inner frame 11 to the fixing shaft 21 as well.

The central insulator 20 prevents the inner frame 11 and the outer frame 23 from being separated from each other by a predetermined length to prevent heat transfer between the inner frame and the outer frame. For this purpose, the inner frame and the outer frame may be made of aluminum or steel, and the central insulation may be made of polyamide, u-PVC or LFT (Long Fiber Thermoplastic). Preferably, a polyamide is proposed. The above-mentioned article material can be similarly applied to a plurality of parts shown below unless otherwise specified. For example, a material such as polyamide may be used for the part that performs the role of adiabatic, and a part for performing the role of the frame may be made of aluminum or the like.

A glass member 70 is provided at one side of the central insulator 20 and the glass member 70 can be completely sealed by the gasket 71 and the sealer 72. Further, since the glass member 70 is provided in triplicate, the heat insulating effect can be maximized.

A lateral insulation material 30 is provided on the opposite side of the glass material 70 when the central insulation material 20 is centered. The lateral heat insulating material 30 can prevent the outside air entering through the gap between the fixing member 1 and the moving member 2, the cold air from the outside air, and the cold air of the outer frame 23 from being transmitted to the room.

An outer cover 22 is provided on the outer side of the outer frame 23 to cover the fixed shaft 21 and the outer frame 23. In addition, the inner frame 11 is provided with a stopper 40 capable of limiting the angle at which the moving member 2 moves.

The motion member 2 is a part that can be illustrated as a door and includes a first door frame 41 and a second door frame 60 that provide a door frame, Side heat insulating material 50 for inserting the two-door frame 60 and fastening them to each other is provided. A door side heat insulating cover (56) is provided on one side of the door side insulating material (50). On the other hand, the door side insulating material 50 is provided with two baffles. The baffle provides three separate interior spaces with door side insulation cover (56). Therefore, it is possible to prevent the outside air coming in through the space between the components, the cold air from the outside air, and the cold air from the external components from being transferred to the room.

A handle 42 is fastened to the first door frame 41 so that the user can hold the door and operate the door. In addition, the first door frame 41 abuts against the stopper 40, and the motion range of the motion member 2 can be limited when the motion member 2 is closed.

One of the factors that deteriorate the heat insulating performance in the curtain wall is that a part that can not be closed due to the movement of the moving member 2 as a part between the fixing member 1 and the moving member 2 may occur, This can be attributed to the increase in the parts that can not be closed. The inventor has provided a first rib 51 to the second door frame 60 and a second rib 52 and a third rib 53 to the door side insulating material 50 in order to solve this problem . The ribs 51, 52, and 53 may be made of polyamide or the like, and may have a slight deformation because they are provided to have a thin thickness toward the end. Therefore, the sealing performance can be improved, and even if partial breakage occurs, the inflow of outside air can be blocked by the other ribs. In addition, two gaskets 54 and 55 are provided in an interval between the stopper 40 and the first door frame 41. The first gasket 54 shields the stopper 40 from abutting against the first door frame 41 and the second gasket 55 covers the stopper 40 from the outside of the stopper 40, (40) and the first door frame (41).

According to the embodiment described above, all five outermost shield structures are employed, three of which are provided with slidable ribs 51, 52 and 53, the remaining two are fixed in position and only slightly deformed It may be provided with gaskets 54 (55) in which shielding may be performed. The ribs and the gaskets may be fastened to each other in such a way that ribs or gaskets are inserted into the grooves of the components to be installed. According to the above-described structure, heat loss due to the inflow of outside air can be minimized on the connecting portion between the movable member 2 that can be opened and the fixing member 1 that supports the moving member 2. Since all five air-shielding structures are used to provide four insulation spaces, the outside air-cooling air can not enter the room. Further, even if any one rib or gasket is broken, the adiabatic effect does not deteriorate. At this time, as long as the length of the door side heat insulating material 50 is maximized and the two ribs 52 and 53 are provided on the door side heat insulating material 50, heat loss due to heat conduction of the heat insulating material itself can be suppressed Heat loss through convection can also be minimized.

A glass member (70) is provided on the door side heat insulating cover (56). The glass member 70 is provided in triplicate to a significant amount of load. Therefore, there is a high possibility that the curtain wall is deformed by the use for a long time, and there is a great possibility that other parts may be damaged by an external impact. For example, when the glass member 70 touches the door-side heat insulating cover 56 provided on the lower side thereof due to an external impact, the cover 56 may be damaged. These problems seriously affect the stability of the curtain wall.

2 is an enlarged view of "A" in Fig.

Referring to FIG. 2, a strut member 73 is provided which extends under the glass member 70 in a state where it is supported by one of the concave grooves of the first door frame 41. The backing member 73 supports the lower surface of the glass member 70 to prevent the glass member from falling down due to its own weight and even if the glass member 70 strikes downward due to an external impact, The cover 56 and the door side heat insulating material 50 can be prevented from being damaged. Of course, a sealer and a gasket are provided for supporting the glass, but in the case of a triple glass, the sealer and the gasket can not support it because it is too heavy. Therefore, the necessity of the above-mentioned strut member 73 arises.

The supporting member 73 is provided with an annular portion 74 which can be hung and supported by the concave groove of the first door frame 41 and a supporting portion 73 extending from the annular portion 74 to the lower side of the glass member 70 A portion 75 is provided. According to such a configuration, the weight of the glass member 70 is supported by the support portion 75, and the force is transmitted to the ring portion 74. As a result, the weight of the glass member 70 can be firmly supported by the first door frame 41.

Further, a supporting rubber 76 is further provided between the stiffening member 73 and the glass member 70. The support rubber 76 can prevent the self weight or external impact of the glass member 70 from being directly applied to the stiffening member 73 or the door side heat insulating cover 56 or the door side insulating material 50 have. In other words, buffering can be performed. Therefore, it is possible to stably support the glass member 70, and it is possible to buffer external shocks, thereby preventing destruction of final parts. In addition, it is possible to prevent breakage of brittle resin material parts and metal material parts.

It is possible to prevent breakage or deformation of a part of the curtain wall by the above-mentioned stretching member 73 and the supporting rubber 76, and it is possible to prevent the frame from being totally deformed even if used for a long time.

The supporting member 73 and the supporting rubber 76 have been described with reference to the moving member 2, but the present invention is not limited thereto. In the case of the fixing member, the supporting member may be similarly applied to support the glass member. In this case, the role of the first door frame can easily predict that the inner frame will perform.

3 is a cross-sectional view of a connecting portion of a curtain wall according to an embodiment, showing a lower side portion. Therefore, the moving member is not provided.

3, the inner frame 11, the bracket 10, the intermediate heat insulating material 20, the fixing shaft 21, the outer frame 23, the outer cover 22 and the glass member 70 are provided, These members are among the descriptions given in Figs. 1 and 2. The same applies except for the description of the specific member provided for supporting the motion member.

A supporting rubber 76 is provided on the lower side of the glass member 70 with reference to the drawing so that the position can be stably maintained without being shaken even when an impact is applied from the outside. A lateral heat insulating material 30 is provided on the opposite side of the glass member 70 with respect to the central heat insulating material 20. The lateral heat insulating material is provided for ensuring the heat insulating performance against the lateral edge portions of the curtain wall where the glass material 70 and the central heat insulating material 20 are not smoothly insulated.

The lateral heat insulating material 30 has a structure in which a first battle 31 and a second baffle 32 are provided in the heat insulating body 36. The ends of the baffles 31 and 32 may be in contact with the central insulator 20. Therefore, the space formed by the inner frame 11, the outer frame 23, and the outer surface portion of the central heat insulating material 20 is divided into three portions, that is, the first space 33, the second space 34, (35). Each space can be shielded.

According to such a heat insulating structure, the cold air from the outer frame can not be directly transmitted to the inner frame 11. In addition, by forming three respective convection spaces, each convection motion does not affect each other. Also, depending on the installed position, it is possible to suppress the cold air that can flow through the boundary between the curtain wall and the general wall.

When the lateral heat insulator 30 is centered on the center heat insulator, it is possible to improve the heat insulating performance at the opposite side where the glass member is installed. Therefore, it is possible to prevent heat loss due to heat transfer between the frame and the frame forming the frame of the curtain wall.

4 is a view showing an installation state of the auxiliary fasteners.

Referring to FIG. 4, the auxiliary fastener 91 can be used at a portion where the inner frame in the vertical direction and the inner frame in the horizontal direction are connected to each other. The auxiliary fasteners 91 can work together with the bracket 10 to obtain an advantage that the strength of the entire frame providing the curtain wall is further increased. The auxiliary fasteners 91 can fasten the central heat insulating material 20 and the inner frame 11 together.

On the other hand, the auxiliary fastener 91 is fastened in a direction perpendicular to the direction in which the bracket 10 is fastened. In other words, since the bracket 10 and the auxiliary fastener 91 clamp the inner frame in the directions orthogonal to the vertical direction inner frame and the horizontal direction inner frame, it is possible to firmly support the external force exerted in any direction . According to this, it is possible to obtain the effect of firmly supporting the glass member 70 provided in the triple-glazing structure.

When the auxiliary fastener 91 is fastened, the fastening member 92 can be inserted into the heat insulating member fastening portion 93 and the shaft receiving portion 94 constituting the side wall of the central heat insulating member 20, Effect can be obtained. For this purpose, the shaft receiving portion 94 may be provided with a width of a predetermined length or more.

According to the auxiliary fastener 91, it is possible to prevent the frame from being twisted or deformed as a whole by the weight of the glass member by connecting the horizontal direction frame and the vertical direction frame together with the bracket, A strong endurance effect can be obtained.

5 is a perspective view showing a state in which the vertical inner frame and the horizontal inner frame are fastened to each other.

Referring to FIG. 5, the transverse direction inner frame 11a and the transverse direction inner frame 11b are provided in directions crossing each other. The front face of the bracket 10 is fastened to the outer face wall of the longitudinal inner frame 11b and the side face of the bracket is fastened to the inner face wall of the transverse direction inner frame 11a. FIG. 4 is a view from right to left when viewed from FIG. 5 as a reference.

The bracket 10 is fastened to the longitudinal inner frame 11b first, and then to the transverse inner frame 11a. Therefore, when a mistake is generated in the fastening when fastening the transverse inner frame 11a and the bracket 10, there arises a problem that the perpendicular angle between the vertical inner frame and the horizontal inner frame is distorted. When the right angle of the frame is twisted, the load of the glass member 70 gradually causes the frame to turn, causing a problem. This problem becomes larger in the case of the glass member 70 provided as triple glass. Therefore, in order to use triple glazing, it is necessary to improve the precision of the frame fastening and maintain the squareness.

6 is an enlarged view of the portion "C" in Fig.

Referring to FIG. 6, it can be seen that the portion where the fastening member 4 is inserted for fastening the inner frame 11 and the central heat insulator 20 constitutes the bent portion 3. In other words, protruded toward the central heat insulator 20. [ The bending portion 3 is further provided with a receiving portion 6 so that the bracket 10 can stably contact both end portions of the bending portion 3 and the receiving portion 6 to maintain its position. The receiving portion 5 may be defined by the bent portion 3, the receiving portion 6, and the bracket 10. The receiving portion 5 is a space in which the screw chip generated when the fastening member 4 digs into the bracket 10 and the bur that is generated when the fastening member 4 penetrates the bending portion 3 is accommodated .

In the absence of the accommodating portion 5, there is a problem that the bracket 6 is spaced apart from the inner frame 11 by a predetermined distance, thereby causing a problem that the perpendicularity between the horizontal frame and the vertical frame is distorted. In order to prevent this, the operator is forced to maintain the position by applying force. However, this is a difficult task, and if a mistake occurs in the work, the reliability of the whole frame is lowered. The receptacle 5 is provided below and above the center insulator 20, respectively.

It is possible to prevent the problem of the breakage and deformation of the related member due to the self weight of the glass member by the above-described structure, and it is possible to prevent the frame from being twisted when used for a long time. In addition, the labor of the operator is reduced during manufacture and the convenience of the operation can be improved.

7 is an enlarged view of the portion "D" in Fig.

Referring to FIG. 7, a process of assembling the central insulator 20 with the inner frame 11 will be described. The inner frame 11 and the central heat insulating member 20 are fastened by the fixing shaft 21 as described above. When the fixing shaft 21 fixes the central heat insulator 20 and the inner frame 11, the fixing shaft 21 first penetrates the central heat insulator 20 and then punctures the inner frame 11 do. At this time, since the central heat insulator 20 has a hardness lower than that of the inner frame 11, there is a problem that the central insulator 20 is lifted during the punching of the inner frame 11, and the fastening becomes difficult. It is also difficult and hard work for the operator to press the central insulator 20. The problem is that the inner frame becomes larger and thicker as a whole in order to support the glass member 70 having a higher weight and becomes larger as the thickness of the inner frame wall increases to fasten the auxiliary fastener 91. [

In order to solve this problem, the inventor considered to assemble the central insulator 20 to the inner frame 11. Such a structure is clearly shown in Fig. 7, in which an inner pocket 7 is formed at the edge of the inner frame, and a heat insulating material holding end 9 provided at an end portion of the central heat insulating material 20 is inserted into the inner pocket 7 . At this time, the inner protrusion 8 is provided at the inlet of the inner pocket 7 so as to narrow the inlet of the inner pocket 7, rather than the inner space thereof.

According to the configuration described above, the operator can hold the central heat insulator 20 and push the heat insulating retaining end 9 into the inside pocket 7. Since the central insulator 20 is given some elasticity, the inserting operation is not difficult. After the insulator retaining end 9 is inserted into the inner pocket 7, the insulator retaining end 9 is caught in the inner protrusion 8 and is difficult to escape to the outside. Therefore, the center insulator 20 does not float while the fixed shaft 21 is inserted. According to such a configuration, the fastening process can be easily performed while sufficiently supporting the large weight of the glass member, thereby reducing the manufacturing labor.

On the other hand, the inner latching end 38 of the end portion of the side insulating material 30 is hooked to the entrance of the inner pocket 7. [ As a result, the effect of supporting one end of the lateral heat insulating material 30 can be further expected.

8 is an enlarged view of the portion "E" in Fig.

Referring to Fig. 8, the inner latching end 38, which constitutes one end of the lateral heat insulating material 30, is seated in the mouth of the inner pocket 7, as seen in Fig. The outer side end portion of the outer side frame 23 is connected to the outer side end portion of the outer side frame 23. The outer side frame 23 is provided with an outer side engaging portion 37, The outer latching end 37 may be provided in an annular shape so as to allow elastic deformation during the fitting operation.

According to this configuration, the operator grips the lateral heat insulating material 30 and hooks the inner fastening end 38 at the entrance of the inner pocket 7, and when the outer fastening end 37 is pressed, the annular outer fastening end 37 is resilient So that it can be fitted into the opening of the outer pocket 24. Therefore, the operator can conveniently mount the side insulator 30.

Further, in order to prevent foreign matter from entering from outside, a sealer can be applied to the space between the parts.

9 is an enlarged view of the portion "B" in Fig.

Referring to FIG. 9, the side insulator 30 is provided on the opposite side of the glass member 70, with the fixing shaft 21 as the center, to maximize the adiabatic effect. When the lateral heat insulating material 30 is provided in the gap between the fixing member 1 and the moving member 2, the liquid outside the fixing member 1 and the moving member 2, for example, It prevents water from coming in. To this end, an inflow preventing portion 29 is provided as a structure protruding to the opposite side of the inner engaging end 38. The inflow preventing portion 29 may be provided in a structure in contact with the outer surface of the inner frame 11. [

Since the inflow preventing portion 29 is protruded upward from the heat insulating body 36, the height of the inflow preventing portion 29 is higher than the heat insulating body 36. Therefore, even if the liquid flows along the heat insulating body 36, it can be blocked by the inflow preventing portion 29 and can be prevented from flowing into the inside, so that heat loss due to a large amount of cold liquid can be eliminated. In addition, the indoor environment can be further improved.

According to the present invention, it is possible to eliminate the heat loss through the frame, to prevent the inflow of outside air and the inflow of outside liquid from the connecting portion between the moving member and the fixing member, to improve the heat insulating performance of the visual opening member, It is possible to obtain an advantage of improving the heat insulation performance by blocking cold air that can be introduced. Further, even if the weight of the glass member is increased for the purpose of improving the heat insulating performance, it is possible to support the glass member, thereby preventing breakage and deformation of the component and preventing the frame from being twisted. In addition, there is an advantage that the convenience of the operator is improved by simplifying the fastening process of the product.

In view of these advantages, the present invention improves the heat insulation performance of a curtain wall, thereby achieving an advantage that energy consumption can be remarkably reduced.
