Description

Window frame assembly of curtain wall and assembly device thereof

The present invention relates to a window frame assembly of a curtain wall system and an assembly device thereof, and more particularly, a window frame frame of a curtain wall system capable of improving thermal insulation performance 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 device thereof.

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

Here, the window frame assembly (A) includes an inner frame (A1) positioned on the indoor side, an outer frame (A2) positioned on the outdoor side, and an insulation bar connecting between the inner frame (A1) and the outer frame (A2). It includes A3).

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 under strong wind or external force, so the structural strength is high and the weight is made of aluminum, and the insulation bar (A3) has a lower structural strength than the inner frame (A1) or the outer frame (A2), but is made of a synthetic resin material having excellent thermal insulation performance in order to compensate for the low thermal insulation performance of aluminum material.

The inner frame (A1), the outer frame (A2), and the insulation bar (A3) are usually manufactured with an extruder, and are continuously extruded in the longitudinal direction to have a certain cross-section and manufactured to a length of approximately 6 m, and then the size of the window frame It is used by cutting it into appropriate lengths, and the cross-sectional shape of the inner frame (A1), the outer frame (A2), and the insulation bar (A3) is designed in various ways as necessary.

Since the curtain wall system constitutes the exterior wall of a building that blocks indoors and outdoors, insulation performance is very important. However, since aluminum has a relatively high thermal conductivity among metals, for example, if all of the inner frame (A1), outer frame (A2) and insulation bar (A3) are made of aluminum material, the inner frame located indoors If a temperature difference occurs between (A1) and the outer frame (A2) located on the outdoor side, heat exchange quickly through the heat insulation bar (A3) to greatly reduce the heat insulation performance, thereby reducing the cooling and heating efficiency of the building.

Therefore, the window frame assembly (A) needs to improve the insulation performance for the above-described cooling and heating efficiency. For this purpose, the inner inner frame (A1) and the outer outer frame (A2) of the indoor side are separated and arranged 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 insulation performance is formed between them. It is combined through an insulation bar (A3). In this way, the insulation bar (A3) blocks heat transfer between the inner frame (A1) and the outer frame (A2) as much as possible, thereby improving 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 and connected between them, so the coupling between them must be very strong to shake each other. Without it, all of them can be fully functional by maintaining an integral form.

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

First, as shown in Figure 2a, the pressure-contact method is formed by protruding coupling protrusions (A30) at both connection ends of the insulation bar (A3) in the connection direction, and corresponding inner frame (A1) and outer frame (A2) The coupling protrusion (A30) is inserted into the defect groove (A10, A20) by protruding in the connecting direction by forming a coupling groove (A10, A20) having a corresponding shape into which the coupling protrusion (A30) can be inserted Then, as indicated by the arrow, by pressing both the contact projections (A11, A21) of the coupling groove (A10, A20) toward the coupling projection (A30), as shown in Figure 2b, the coupling projection (A30) and the coupling groove (A10, A20). ) Is tightly attached to form a solid bond.

At this time, when the contact projections (A31) are formed on both sides of the coupling protrusion (A30) to deform by pressing the contact projections (A11, A21) from both sides toward the coupling projection (A30), the contact projections (A11, A31) in the contact groove (A31) A21) can be firmly coupled without being separated in the direction of interconnection by being inserted and held in close contact with each other.

Therefore, this pressure contact method necessarily forms a coupling groove (A10, A20) having contact projections (A11, A21) on the inner frame (A1) and the outer frame (A2) made of aluminum material that is difficult to restore when pressure deformation, A coupling protrusion A30 must be formed on the insulating bar A3 made of a synthetic resin material that can be restored when deformed under pressure.

In addition, when the inner frame (A1) and the outer frame (A2) are manufactured, as shown in Fig. 2a, both the contacting protrusions (A11, A21) of the coupling grooves (A10, A20) are formed to slightly open so that the insulating bar ( When inserting the coupling protrusion (A30) of A3), sufficient space is secured, and the pressure of the contact protrusion (A11, A21) is perpendicular to both sides of the connection direction center line (XX) of the insulation bar (A3). By pressing in the direction of the arrow, the contact protrusions A11 and A21 are inserted into the contact recess A31 as shown in FIG. 2B, and at the same time, they are in close contact, thereby forming a solid coupling.

In such a pressurized contact method, by inserting the coupling protrusion (A30) of the insulation bar (A3) into the coupling grooves (A10, A20) of the inner frame (A1) and the outer frame (A2), pressurized while transferring to the transfer line of the assembly device. Since the contact protrusions (A11, A21) are pressed from both sides with a roller to be bonded, it has the advantage that the assembly is good and productivity can be improved, and the bonding force is also very strong.

However, in the press-contact method as described above, after inserting the coupling protrusions A30 into the coupling grooves A10, 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 projections 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 Figure 2a, the length (L) in the connection direction of the insulation bar (A3) is bound to be limited, and the longer the length (L) in the connection direction of the insulation bar (A3) is, the better the insulation performance. The disadvantage is that there is a limit to further improvement.

On the other hand, the force-fitting method is disclosed in the insulating curtain wall of Korean Patent Registration No. 10-1813248, which is not a method of pressing the coupling portion with a pressure roller of the assembly device, as shown in FIGS. 3A and 3B. , It is possible to form the fixed coupling portions (17, 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) There is an advantage in that the insulation performance is improved because the length of the connection direction can be formed longer than that of the pressurized contact method.

That is, the force-fitting method includes forming elastic coupling portions 11 and 15 capable of elastic deformation and restoration on the insulating bar 3 made of a synthetic resin material capable of elastic deformation and restoration, and an inner frame made of aluminum material ( 1) When the fixed coupling portions (17, 21) are formed and the elastic coupling portions (11, 15) are strongly pushed into the fixed coupling portions (17, 21) to fit, the elastic coupling portions (11,15) of a synthetic resin material. It is a method that is elastically deformed and is coupled by force fitting to the fixed coupling portions 17 and 21 while being in its original position.

However, since this force-fitting method is fixed by a coupling force that restores the elastic coupling portions 11 and 15 by elastic deformation, it is not possible to expect a stronger coupling force than the joining close method, and thus, when an external force acts on the connecting portion, it flows easily. It is difficult to integrally and firmly maintain the overall configuration of the window frame assembly. To this end, when reinforcing with a fixing means such as a fixing screw, the assembly work of the window frame assembly becomes very cumbersome, and a lot of work time is required, which greatly reduces productivity.

The present invention is to solve the above problems in consideration of the conventional problems, and the object is to secure fast assembly and a solid coupling force by combining the inner frame of the window frame assembly and the insulating bar in a pressure-contact manner, and the inner frame like a force-fitting method.
