Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curtain wall closing cover,

The present invention relates to a curtain wall system, and more particularly, to a curtain wall system that includes a mullion (hereinafter referred to as a vertical structural member), which is a structural member installed vertically between a floor and a floor to receive a wind load or the like applied to the curtain wall, (Hereinafter referred to as "horizontal structural member"), which is a sub-structural member connected horizontally between the upper and lower horizontal walls of the curtain wall, The present invention relates to a one-touch detachable type curtain wall finishing cover.

Generally, in a structure that supports horizontal loads due to vertical load, wind, earthquake, etc. due to the structure of pillars and beams, which are the main structure of the building, the walls are merely curtains that partition the spaces. Also known as non-proof bulkhead.

Such a curtain wall is used to block rain or wind from the outside, to block noise or heat, to prevent the column and the beam from being exposed to the outside, and the wall using glass or the like has a great function as a modern architecture, particularly for exterior use.

The curtain wall system according to the construction specifications can be classified into a unit system and a stick system by division.

The unit system is a panel system that assembles and assembles each component into a factory panel and installs a glass panel so that it can be finished at the factory and the quality can be improved. In the construction of a high-rise or high-rise building which is simplified and has excellent ability to cope with the vertical inter-story displacement, it is difficult to assemble the exterior scaffold.

This is a disadvantage in that it is difficult to demonstrate flexibility in the field and requires a preparatory period of at least three months because it is a factory prefab structure in which components are assembled in a batch ordering method of frame, glass, and panel.

Stick System is a method of assembling each component in the field one by one. It is widely used in middle and low-rise buildings. It is also called knock down system as most of curtain wall construction method. It is known that it is advantageous to start the construction quickly because it is possible to adjust the air because it is excellent in field adaptability, and the preparation period is short, by assembling and connecting the components in the field by the separate ordering method.

A coupling structure of the vertical structural member and the horizontal structural member according to the related art will be described.

As shown in FIG. 1, the vertical structural member has a long span depending on the height of the building. The vertical structural members are installed by being fastened to the slab and the bracket fixed to the floor with through bolts, and are spaced apart at a predetermined interval.

At this time, in order to firmly support and adhere the heat insulating glass 3 as an outer wall material to the open part formed by intersecting the vertical structural member 1 and the horizontal structural member 2, the structural members 1 and 2 are provided with surface clearance A glass insert portion 4 for forming an end clearance is formed.

The heat insulating glass 3 is fixed to the glass insertion part 4 by adhering the backing material 5 and the sealant 6.

Such a conventional construction is variously known as shown in Figs. 1 (a) to (c).

The structural members 1 and 2 are applied to vertical or horizontal structural members which are formed by extrusion molding in the form of a bar and which are adapted to be fitted with insulating glass on both sides.

The structural member shown in Fig. 1 (a) is integrally divided into an inside side having a large cross-sectional volume centered on the glass inserting portion 4 and an outside side having a narrow cross-sectional volume.

When the heat insulating glass is sandwiched between the openings by the integral structure, the end clearance d1 must be increased because the heat insulating glass larger than the area of the openings must be sandwiched between them. Conversely, the engaging dimension d2 for supporting the glass becomes small, It is a serious obstacle to safety.

At the same time, assembly tolerance management is indispensable even in the field construction, so that it takes a long time for construction and construction of an expert is required.

Structural members as shown in Figure 1 (b) are known with some improved proposals.

The upper portion of the outer side is opened with respect to the glass inserting portion 4 and the lower portion thereof is formed in a semi-closed form having the same surface as the lower side of the inside portion of the structural member. And the lower surface of the glass is closed.

Although the end clearance d1 is somewhat reduced and the engaging dimension d2 is somewhat increased in comparison with the above-described type, it is difficult to achieve a firm construction and the fitting state of the cover 7 is unstable, there is a problem.

Since the dimensions of the two types of structural members are only about 5 to 8 mm and 8 to 10 mm, it is impossible to assemble them to the dimension of 15 mm or more required by the specifications. However, since they are constructed at random by the cheap manufacturing cost, A vulnerable problem occurs.

In another proposal, as shown in Fig. 1 (c), the structural members 1 and 2 are divided into an inside side and an outside side in order to increase the size of the engagement and to easily insert the insulating glass in the site, A plurality of projections formed with a bolt slit 81 are formed on the inside member so as to form a bolt projection 8 and a piece An inner cover 83 which is fastened to the inner cover 83 by bolts, and an outer cover 84 which covers the inner cover.

The heat insulating block 82 is fixed to the slit 81 and the inner cover 83 is inserted into the bolt slit 81 through the heat insulating block with the bolt, And then the outer cover is fitted to the inner cover.

However, according to the related art, there is a problem that the manufacturing cost increases due to an increase in the number of parts, and a long construction time is required due to an increase in the number of workings due to assembly and assembly of many accessories, The cover member is displaced at a predetermined position and is pushed or pulled to generate a gap (0.5 to 1 mm) with the horizontal structural member, while the bolt fastening is performed at a predetermined position at an arbitrary irregular and arbitrary position . This problem is caused by the displacement due to the bolt fastening, and the occurrence of the gap causes a serious side effect in the adiabatic and the inflow of external foreign matter such as noise and rainwater, and therefore, there is a problem to be reworked.

In addition, since the outer cover is hammered by a hand tool such as a hammer for binding to the inner cover and is forced to press-fit, a stress is generated. As a result, the thickness of the cover must be at least 3 mm thick, Which increases the self weight of the curtain wall, which is very unreasonable in terms of stability.

In addition, in the case of carelessness in the strike for joining the outer cover 84 during construction, there is a problem that the heat insulating glass may be damaged. In addition, the outer cover to which the impact is applied is detached for partial repair such as replacement of broken glass, The material can not be reused and the heat insulating block is interposed. However, there is a great problem that heat transfer is accompanied by external force transmission by the pieces (bolts).

Disclosure of Invention Technical Problem [8] The present invention has been made to solve the problems of the prior art as described above, and it is intended to solve the following problems.

The present invention relates to a curtain wall system which is constructed by inserting a heat insulating glass in an opening defined between a vertical structural member and a horizontal structural member, thereby increasing the thermal insulation effect and reducing the end clearance, Type curtain wall finishing cover.

The present invention eliminates the complexity and complexity of construction by simply inserting the outsider side cover by simply wrist snapping in the field construction, so that the construction period can be greatly shortened and the on-site assembly error is reduced, Provide a deadline cover.

The present invention provides a curtain wall finishing cover of a one-touch detachable type which can be assembled even if it is an unskilled worker by simplifying the structure member and the assembled parts, thereby greatly reducing the manufacturing cost.

The present invention provides a one-touch detachable type curtain wall finishing cover which prevents displacement of a structural member to prevent irregular tightening external force applied during construction and prevents any clearance from occurring when assembled and assembled members are cut.

According to an aspect of the present invention, there is provided a floor structure comprising a plurality of vertical structural members spaced apart from each other in a lateral direction of a building, a plurality of horizontal structural members orthogonal to the lateral direction from the vertical structural member, A curtain wall system for fastening and fixing an insulating glass to an opening of a structure according to a partition of two structural members, comprising: an extension part extending from an inside side bar constituting a structural member to an outside side to form a glass insertion part; A "T" type bracket is formed at the end of the extension part, and the bracket is fixed over the two end points provided at the upper and lower ends of the "T" type bracket.

The relative length of the upper and lower jaws L3 and L4 of the "T" bracket is such that the depth L1 of the upper step and the depth L2 of the lower step is L2 = L1 * = L3 * 2, so that the lower step is inserted deeply and the upper step is caught, and the lower step is pushed downward vertically to couple the two end points with one-touch operation.

The contact surface of the "T" type bracket and the finish cover has a plurality of inclined slopes so that the upper step and the upper engaging jaw can be prevented from rotating when the one-touch coupling is engaged, So that the voids are excluded and fixed firmly.

In the present invention as described above, the heat insulating glass is placed deeply in the extended part extending from the inside to the outsider at the time of the field construction so as to form a maximum size of 15 mm or more required by the specification. Since the extension of the direction is short, there is no obstacle to inserting the heat insulating glass. After the glass is inserted, the finish cover is inserted by one touch to complete the bonding work.

According to the present invention, in the construction of the heat insulating glass in the openings partitioned between the vertical structural member and the horizontal structural member of the curtain wall system, the end clearance is reduced to increase the heat insulating effect and increase the sticking dimension, , It is possible to reduce the construction time and the field assembly error because the complexity and complexity of the construction are eliminated by simply joining the outsider side finishing cover by simply wrist snapping at the time of construction. Therefore, it is possible to construct a beautiful appearance, The manufacturing cost is greatly reduced by simplifying the assembly parts.

Further, since the irregular fastening external force applied during construction is eliminated, it is possible to prevent the structural member from being displaced, prevent any clearance from occurring when assembling the designed cut members, It is an invention having various excellent effects such as being able to assemble and construct even if it is an unskilled person.

Hereinafter, the technical idea of the present invention will be described in more detail with reference to the accompanying drawings.

3 and 4, the present invention includes a plurality of vertical structural members spaced apart from each other in a lateral direction of the building, a plurality of horizontal structural members orthogonal to the lateral direction from the vertical structural member and spaced apart from each other in the longitudinal direction of the building, And a fixing part (30) extending from the inside side bar constituting the structural member to the outside side and forming the glass insertion part. The curtain wall system according to claim 1, Type bracket 20 is formed at the end of the extended portion and is fixed over two end points provided at the upper and lower ends of the "T"

The bracket 20 is formed such that the relative depth of the depth L1 of the upper step 21 and the depth L2 of the lower step 22 is L2 = L1 * 2, 11) The relative length of the length L3 and the length L4 of the lower latching jaw 12 is such that L4 = L3 * 2, so that the lower step 12 is inserted deeply and rotated so as to catch the upper step, 22 and the engagement protrusions 11, 12 are coupled by a one-touch operation.

The lower end of the contact surface 14 of the finish cover 10, which is in contact with the bracket 20 of "T" type, forms a slope inclined portion 13 so that the upper step 21 and the upper engagement step 11 are avoided Type bracket 20 when the cover 10 is pivoted and is pushed down vertically to complete the engagement, so that the gap between the finish cover 10 and the "T" bracket 20 is securely fixed.

At the end of the lower step 22 of the "T" bracket 20, the projection 23 is protruded and protruded in the inserting direction of the lower stopping jaw 12 to prevent the flow of the lower stopping jaw 12 are in close contact with each other.

The finishing cover 10 is formed to have the same width as the width of the bars constituting the structural members 1 and 2.

This is because the contact surface of the finishing cover 10 that is in contact with the bracket 20 of the "T" type is composed of a multi-step inclined contact surface 14a and the "T" bracket 20 The upper end 21a and the upper stopping jaw 11 are prevented from rotating while the lower end of the upper cover 21 and the lower end of the upper cover 21 are engaged with each other, Quot; type bracket 20, and the multi-step inclination of the contact surfaces 14a and 24a sequentially forms the facing force, thereby achieving a more rigid connection.

The present invention having the above-described technical structure enables extremely convenient, accurate and quick construction for a construction site.

Please refer to FIG. 7 to FIG. 8.

As is well known, when a curtain wall is to be installed in a building, a vertical structural member is firmly fixed to a slab or the like of a building, a plurality of vertical structural members are arranged at a predetermined distance in the lateral direction, Glass walls or doors or windows are to be constructed.

The vertical and horizontal structural members of the present invention are pre-assembled with an extension 30, which is a heat insulating block of polyamide material, and a "T" bracket 20 at the end of the extension.

Of course, the pre-assembly is convenient for construction and transportation, and may be assembled in the field.

After the vertical and horizontal structural members 1 and 2 are fixedly coupled as described above, the heat-insulating glass 3 previously assembled is fitted on the extended portion 30 in a downward direction, And the upper and lower extensions of the "T" type bracket 20 do not interfere with the insertion of the glass, so that the heat insulating glass has a minimum bite size of 15 mm in accordance with the requirements of the construction specification and can be built in.

After the heat insulating glass built-in is completed, the finish cover 10 is aligned face-to-face as shown in Fig. 8 so that the lower stopping jaw 12 is positioned on the lower side of the "T" So as to be inserted deeply into the depth L2 of the step 22.

At this time, the rotation interference is excluded by the escaping of the inclined surface 13 of the finish cover.

The upper end stop 11 of the finishing cover and the upper end 21 of the "T" -shaped bracket 20 are moved up to a position where the interference is excluded, When the entire cover 10 is raised and then pressed downward, the lower engaging jaw 12, which has maintained the depth-coupled state, is lowered and the upper engaging jaw 11 is lowered, 21, the lower latching jaw 12 is held in the lower step 22 and the coupling is completed.

At this time, in order to make the joint and the disassembly operation robust, soft and soft, the upper step 21 at the engagement position is fitted to the upper gully jaw 11 and its groove, and the projection 23 are also closely protruded from the inner surface of the lower engaging jaw 12 to be engaged, so that the shaking clearance is minimized to maintain the rigidity.

On the other hand, the contact surface 14a of the finishing cover 10 facing the contact surface 24a of the "T" -shaped bracket 20 described in the modified embodiment is formed in multiple stages so as to mutually pressurize, And when the coupling is completed, the coupling is maintained tightly with the minimum tolerance.

When the coupling is completed, the backup material 5 and the sealant 6 are finished as known.

In the present invention, after finishing the site, the finish cover 10 is disassembled in reverse order as described above such as re-work due to breakage of glass or the like and change of outer diameter of the structural member (outer terrier) It will be appreciated that the one-touch coupling and disassembly is possible so that the construction can be carried out easily without the need of any other tool.

On the other hand, the present invention comprises a finishing cover 10a in which an upper portion and a front portion of a finishing cover are removed as shown in Fig.

This is configured to be applied to the case where the outer side of the heat insulating glass is made to be exposed in the form of glass, so that the upper and lower portions of the cover are partially escaped and removed so that the upper and lower widths of the cover are reduced. Since the exposure is performed, it can be applied to the construction of the glass exposure type while slimly reducing the width of the blunt finish cover.
