Description

Window frame assembly of curtain wall system and assembly device thereof

The present invention relates to a window frame assembly of a curtain wall system and an assembling apparatus thereof, and more particularly, to a window frame frame of a curtain wall system in which the insulation performance can be improved by increasing the length in the connection direction of the insulation bar coupled to the inner frame. It relates to an assembly and an assembly apparatus thereof.

In general, the curtain wall system constituting the exterior wall of a building is installed between the window frame assembly (A) and the glass (B), and the window frame assembly (A) and the glass (B) as shown in FIG. 1 to maintain airtightness. At the same time, it is composed of a sealing member (C) for supporting the glass (B).

Here, the window frame assembly (A) includes an inner frame (A1) located on the indoor side, an outer frame (A2) located on the outdoor side, and an insulating bar connecting between the inner frame (A1) and the outer frame (A2) ( A3) is included.

The inner frame (A1) and the outer frame (A2) must support the overall load and maintain the fixed state of the glass (B) firmly even in strong winds or external forces. (A3) has lower structural strength than the inner frame (A1) or the outer frame (A2), but is made of a synthetic resin material with excellent insulation performance to compensate for the low insulation performance of aluminum material.

The inner frame (A1), the outer frame (A2), and the heat insulation bar (A3) are usually manufactured by an extruder, and are continuously extruded in the longitudinal direction to have a constant cross section to produce a length of about 6 m, and then to the size of the window frame. It is cut to an appropriate length and used, and the cross-sectional shape of the inner frame (A1), the outer frame (A2) and the insulation bar (A3) is variously designed as needed.

Since the curtain wall system constitutes the exterior wall of a building that blocks the indoor and outdoor areas, thermal insulation performance is very important. However, since aluminum has relatively high thermal conductivity among metals, for example, when the inner frame A1, the outer frame A2, and the heat insulation bar A3 are all made of aluminum, the inner frame located indoors When a temperature difference occurs between (A1) and the outer frame (A2) located on the outdoor side, heat exchange is rapidly conducted through the heat insulating bar (A3), thereby greatly reducing the insulation performance, there is a problem of lowering the cooling and heating efficiency of the building.

Therefore, the window frame assembly (A) needs to improve thermal insulation performance for cooling and heating efficiency as described above. To this end, the indoor inner frame (A1) and the outdoor outer frame (A2) are separated and disposed to be spaced apart by a predetermined length (length according to the thickness of the installed glass (B)), and a synthetic resin material having excellent thermal insulation performance is formed between them. It is combined through the insulation bar (A3). As a result, the insulation bar (A3) blocks heat transfer between the inner frame (A1) and the outer frame (A2) as much as possible, thereby improving the insulation performance.

On the other hand, in the window frame assembly (A), the inner frame (A1) and the outer frame (A2) are formed separately, and the insulation bar (A3) is coupled therebetween and is connected. Without it, all functions can be maintained by maintaining an integral form.

As a coupling method of the window frame assembly (A), a press-fit method and a press-fit method are known.

First, as shown in Fig. 2a, in the press-fitting method, coupling protrusions A30 are formed protruding in the connection direction at both connection ends of the insulating bar A3, and the corresponding inner frame A1 and the outer frame A2 are formed. On the opposite surface (connection surface) of the coupling protrusion (A30), coupling grooves (A10, A20) of a corresponding shape into which the coupling protrusion (A30) can be inserted are formed to protrude in the connection direction, and the coupling protrusion (A30) is inserted into the defect grooves (A10, A20). Then, as indicated by the arrow, by pressing the both contact protrusions (A11, A21) of the engaging grooves (A10, A20) toward the engaging projection (A30), as shown in FIG. 2b, the engaging projections (A30) and the engaging grooves (A10, A20) ) to form a strong bond.

At this time, close contact grooves (A31) are formed on both sides of the engaging protrusion (A30), and when the adhesion protrusions (A11, A21) are pressed and deformed from both sides toward the engaging projection (A30), the adhesion protrusions (A11, A11, A21) can be firmly coupled without being separated in the interconnection direction by being inserted and held in close contact with each other at the same time.

Therefore, in this press-fitting method, coupling grooves A10 and A20 having close contact protrusions A11 and A21 are formed on the inner frame A1 and the outer frame A2 made of an aluminum material, which is difficult to be restored when subjected to pressure deformation. The coupling protrusion A30 must be formed on the heat insulating bar A3 made of a synthetic resin material that can be restored during pressure deformation.

In addition, when the inner frame (A1) and the outer frame (A2) are manufactured, as shown in FIG. 2A, both contact protrusions (A11, A21) of the coupling grooves (A10, A20) are formed so that they are slightly widened to form an insulating bar ( A space is sufficiently secured when inserting the coupling protrusion A30 of A3), and the pressing of the contact protrusions A11 and A21 is perpendicular to both sides based on the connection direction center line XX of the insulating bar A3 as a reference. By pressing in the (arrow direction), as shown in FIG. 2b , the contact protrusions A11 and A21 are inserted into the contact groove A31 and at the same time closely adhere to the contact groove A31, thereby forming a firm coupling.

In such a press-fitting method, the coupling protrusion A30 of the heat insulating bar A3 is inserted into the coupling grooves A10 and A20 of the inner frame A1 and the outer frame A2 and transferred to the transfer line of the assembling apparatus while being pressurized. Since the adhesion protrusions A11 and A21 are combined by pressing from both sides with a roller, the assembly is good, productivity can be improved, and the bonding force is also very strong.

However, in the press-fitting method as described above, after inserting the engaging protrusions A30 into the engaging grooves A10 and A20, the inner frame A1 and the outer frame ( Since the pressure roller of the assembly device must be inserted between the opposite surfaces of A2), the contact protrusions A11 and A21 must be formed to protrude from the opposite surfaces of the inner frame A1 and the outer frame A2 in the connection direction.

Therefore, as shown in FIG. 2a, the length L in the connection direction of the heat insulating bar A3 is inevitably limited, and the longer the length L in the connection direction of the heat insulating bar A3, the better the heat insulation performance. There is a disadvantage that there is a limit to further improvement.

In contrast, the press fit method is disclosed in the insulation curtain wall of Korean Patent Registration No. 10-1813248, which is not a method of pressing the coupling portion with the pressure roller of the assembly device, as shown in FIGS. 3A and 3B. , it is possible to form the fixed coupling portions 17 and 21 of the inner frame 1 in the inner position of the inner frame 1 without protruding from the opposite surface (connection surface) in the connection direction, and thereby the insulation bar 3 The length of the connection direction can be formed longer than that of the press-fit method, so there is an advantage in that the insulation performance is improved.

That is, in the press fit method, elastically deformable and resilient elastic coupling portions 11 and 15 are formed on the insulating bar 3 made of a synthetic resin material capable of elastic deformation and restoration, and an inner frame made of an aluminum material ( 1) is formed with fixed coupling parts 17 and 21, and when the elastic coupling parts 11 and 15 are strongly pressed to fit the fixed coupling parts 17 and 21, elastic coupling parts 11 and 15 of synthetic resin material are formed. It is elastically deformed, and is coupled to the fixed coupling parts 17 and 21 by force fitting while in the original position.

However, in this forced fitting method, since the elastic coupling parts 11 and 15 are fixed with a coupling force that is restored by elastic deformation, a stronger coupling force cannot be expected than the addition bonding method. It is difficult to firmly and integrally maintain the overall configuration of the window frame assembly. For this purpose, when separately reinforced with a fixing means such as a fixing screw, the assembly operation of the window frame assembly becomes very cumbersome and takes a lot of time, which greatly reduces productivity.

The present invention is intended to solve the problems of the prior art as described above, and its purpose is to secure quick assembly and strong bonding force by combining the inner frame of the window frame assembly and the insulating bar in a press-and-tight manner, and the inner frame as in the press-fit method.
