The present invention relates to a railing structure installed in a balcony or the like. More specifically, the present invention relates to a fireproof railing structure in which a firewall and a railing are integrated.

In general, apartments and villas in the form of apartment houses have balconies.

The balconies of the apartments are separated from the living room or the room, and the railings of the window type are installed to prevent the falling accident. Recently, as the balcony is allowed to be used as a living room or a room, the balcony is being extended to utilize not only the existing use but also various spaces such as a living room, a warehouse, a playroom, and the like. Currently, multigenerational apartment buildings, such as apartments, have to take some safety measures in accordance with the Building Act's decree to extend their balconies. An important part of these safety measures is the installation of fire protection panels between handrails and living room windows to prevent the spread of fire, that is, the flames generated from the lower floors in the event of a fire.

In the case of balcony expansion work, a separate fireproof board is installed between the balustrade and living room windows installed on the balcony of the apartment. Such a structure has a disadvantage in that the handrail or the fireproof board is constructed in a separate process, so that the process, time and construction cost are doubled.

In addition, the handrail may have a structure in which various patterns are formed on the front surface. The pattern may be in the form corresponding to the logo of the contractor or construction company.

The handrail may face the outside of the building, and the firewall may be installed to be spaced apart from the handrail toward the inside of the building.

The handrail may be installed at a central portion of the handrail structure, and the firewall may be spaced apart from both sides with the handrail interposed therebetween.

The firewall may be in close contact with both sides of the handrail to form a single structure with the handrail.

The frame is formed with a space between the grooves into which the firewall and the railing are fitted on the inner circumferential surface, and a horizontal member installed at the top and the bottom of the firewall and the railing, and a groove connected to the front end of the horizontal member and fixed to the inner circumferential surface. It may include a vertical member formed at intervals and installed at the side ends of the firewall and the railing.

The frame may further include an intermediate member connected between the horizontal members or between the vertical members and supporting an intermediate portion of the frame.

The fixing part is placed on the upper end of the frame and extends between the walls on both sides of the balcony, and the lower flange is bent downward at both ends in the width direction of the support to surround the upper end of the frame, both ends of the support in the longitudinal direction is bent to the wall In contact with the front surface may include a fixing stand formed with a hole is inserted into the bolt for fixing to the wall.

In addition, the fixing part may further include an upper flange formed in an upward direction at at least one of the front end portion of the both ends of the width direction of the support is integrally connected between the fixing base.

Here, the handrail structure may be a structure divided into at least two separate blocks and stacked along both side walls of the balcony. Each block can be made of the same structure, but only different from the handrail structure.

In addition, when the handrail structure is a stacked structure separated into two or more as described above, the fixing portion may further include a block fixing portion for supporting each block of the handrail structure.

The block fixing part extends vertically from the floor of the balcony and supports the front edge of the frame edge of the block, and is bent at right angles from the side to the front member, and is horizontally integral with the side member, the front member and the side member which are in contact with the frame edge side. It may be formed in contact with the bottom of the balcony and the front may include a fixing plate formed with a hole for inserting the bolt for fixing with the balcony bottom.

The block fixing part installed at the position where the block and the block are stacked among the block fixing parts has a front member extending in a width corresponding to the width of the entire front surface of the frame edge of the two convex sides, and the side members are integrally perpendicular to the middle of the front member. It may be formed into a structure that is inserted between the two blocks.

As the balustrade and the firewall are integrated in this way, the construction work can be more easily performed when the balcony is extended.

In addition, it is possible to construct a railing or a firewall at a time to reduce the construction period, it is possible to minimize the cost of overlapping construction.
