Description

[0001] Detachable open joint structure between floors [0002]

[0001] The present invention relates to an open joint structure between layer units that enables joining and separation between layer units installed on the same layer in constituting an outer shell of a building. Especially, it is possible to secure wind and air tightness by installing double gaskets, To an inter-layer unit openable joint structure capable of separating the layer units from each other and facilitating detachment of the layer units by allowing mutual separation and opening at the time of disassembly and replacement.

When the exterior of the building (wall or window) is dry-constructed, it is possible to secure a beautiful appearance according to the demand of the customer, and the air can be shortened compared to the construction of the concrete wall. Conventionally, when a jacket is used, there is a problem that the tower crane is used, so that the operation is troublesome and assembly work is difficult. In addition, since additional insulation should be applied to the interior and exterior finishing materials, the air of the outer casing has to be long.

Accordingly, the present applicant has developed a layer unit which can be assembled and installed in a tilting manner on the inner side of each layer, and is easily detachable and attachable when necessary. In this case, it is required to provide a wind-resistant coupling between the layer units in the same layer, and to be detachable and attachable at the time of replacement. Therefore, an open joint structure between the detachable layer units is required.

As a background of the present invention, Korean Patent Registration No. 10-1215467 has proposed a variable curtain wall sheath structure based on a module system. A multi-story building frame in which interlayer slabs are constructed in the same plane by a wall or a ramen structure; An outdoor module installed in the module frame structure so as to protrude outwardly from the opening of the multi-story building frame to cover the interlayer slab and to conform to the window module or the heat insulation panel module; A window module or an insulation panel module installed inside the module frame of each of the exit frames; An extension frame installed on a surface of a building frame surrounding the exterior frame, wherein the extension frame is installed such that a module frame structure of the exterior frame extends horizontally and vertically; And an insulating panel module installed on a surface of a building frame between the exit frame and the extension frame.

Accordingly, since the basic frame constituting the outer surface of the building is configured in a modular manner capable of accommodating various variables, diversity and functionality can be imparted to the elevation of the building, and since the frame is installed in a retractable fixed manner, Stability can be easily secured.

However, the above background art has a disadvantage that disassembly and reinstallation are insufficient because the frame has a structure for installing the frame in a pull-in manner.

Another background art of the present invention is Korean Registered Patent Registration No. 10-0989934, which proposes a structure of a prefabricated curtain wall module and a construction method thereof. A shock absorber which is fixedly installed on the outer wall of each slab of the building at regular intervals, and prevents the curtain wall from being damaged even if the building is shaken due to an earthquake or any other cause; A curtain wall module assembled to the upper and lower shock absorbers and having a T bar, a vertical / horizontal curtain wall bar, and a set of double-layered glass; And another reinforcing horizontal curtain wall bar is fixedly installed between the curtain wall module and the curtain wall module so as to attach another multi-layer glass.

Therefore, the curtain wall module can be standardized and unified so that it can be assembled easily even for the unskilled worker. If any part of the curtain wall is damaged, it can be replaced only, so that it can be easily attached and detached during maintenance and repair. .

However, the latter background technology has a problem in that it is difficult to detach and attach by forming the outer skin with a double-layered glass and finishing with silicon.
