The present invention relates to a prefabricated stair railing structure for building, and more particularly, to a step of having a wide width and inclination, and easy to apply accordingly, the installation and maintenance of the railing is easy and the prefabricated stair railing structure for building with a beautiful appearance. will be.

In most construction sites, when framing and slab construction is completed, various internal constructions are performed inside the building. At this time, temporary staircases are installed on the stairs to promote worker safety.

After finishing the internal finishing work inside the building, all temporary railings are dismantled and removed, and permanent railings are installed in place. In other words, railings made of steel, stainless steel, and aluminum, which are installed for safety in stairs of apartments and office buildings, are permanent rails permanently installed at the completion stage of construction.

However, this permanent rail was made using iron, stainless or aluminum products. However, when the stair railings are made of these products, there are the following problems.

In other words, when constructing railing of iron products, it is necessary to weld all the pillars, span and liver of railing at the construction site where the stairs are constructed. Therefore, the construction site is complicated and there is a risk of safety accident. Due to the painting work, the painting state is not good, and there is a problem in that even if the painting, the welded portion is easily corroded and rust occurs in this portion. When the railings of stainless steel products are installed, the color of the railings is not uniform because they are not painted, and it is impossible to make a beautiful colored railing that fits the taste of the consumer. When the handrail is constructed of aluminum products, since the rivets or screws are coupled to the support post, the span, and the liver, there is a problem that the bonding strength is weak and the durability is short.

In addition, these conventional railings have to be welded and constructed at appropriate widths and intervals according to stairs having various inclinations, and thus, installation is complicated and maintenance is difficult.

The present invention is to solve the problems as described above, it is easy to apply to the stairs having a variety of widths and inclinations accordingly easy to install and maintenance of the railings and provides a prefabricated stair railing structure for building beautiful appearance. There is this.

In order to achieve the above object, the present invention is a pair of fixed plate having a fastening tube protruding upward in the center of the plate body fixed to the edge of the staircase;

Immediately the lower end of the "∩" shape is inserted into the fastening pipe of the fixing plate, respectively, fastened by fastening bolts, long grooves are formed in the center in the longitudinal direction, and a plurality of fixing grooves are formed at regular intervals on the inner side of the upper side. Handrail frame;

The inner circumference is screwed by the coupling bolts respectively, and a coupling screw thread is formed on the inner outer circumference, and a pair of fixed bars having shaft holes formed at the other end thereof;

One end is fixed to the fixing groove of the handrail frame and the other end is latched to protrude out through the long groove;

A rotation fastener having one end fastened to the latch and the other end axially coupled to the shaft hole of the fixing bar;

Both inner circumferences of the tubular body have connecting rings each having an inner threaded portion screwed to the coupling screw thread of the fixing bar, and the adjacent connecting ring is axially rotatably coupled by the connecting bar, so that the fixing bar is adjacent to the other fixing bar. It is characterized by having a fixing bar connector for maintaining the interval of.

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

Figure 1 is a perspective view showing the construction of the prefabricated stair railing structure for the embodiment of the present invention, Figure 2 is an exploded perspective view showing the fastening of the prefabricated stair railing structure for the embodiment of the present invention, Figure 3 is a prefabricated building for the embodiment of the present invention This is a side cross-sectional view showing the operation of the stair railing structure.

For reference, in describing the present invention, when it is determined that a detailed description of related known functions or configurations may unnecessarily obscure the subject matter of the present invention, the detailed description thereof is omitted.

In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of a user or an operator.

Therefore, the definition should be made based on the contents throughout the specification.

The prefabricated stair railing structure for building according to the present invention includes a fixed plate 20 for fixing the handrail frame 10 to the stairs 70, a handrail frame 10 fixed at both ends to the fixed plate 20, and an adjacent handrail frame ( 10) fixing bar 30 for fixing the connection, the clasp 40 fixed to the handrail frame 10, the rotation fixture 50 for connecting the clasp 40 to the fixing bar 30, and adjacent fixing Consists of a fixed bar connector 60 for fixing the bar 30.

The fixing plate 20 is a plate for fixing the handrail frame 10 to the edge of the staircase 70 in a pair, is fixed by an anchor 22, a fastening tube 21 protruding upward in the center is formed railing The lower end of the frame 10 is inserted and fixed.

The handrail frame 10 is a "∩" shape immediately, the lower end is inserted into each of the fastening pipe 21 of the fixing plate 20 and fastened to the fastening bolt 13, the center groove 11 in the longitudinal direction in the center Is formed, a plurality of fixing grooves 12 are formed in the upper inner surface at regular intervals.

The fixed bar 30 is a pair of left and right tubular body, one side inner circumference is screwed by the coupling bolt 31, respectively, the outer peripheral edge of the end of the coupling screw thread 32 is formed, respectively, the other end A shaft hole 33 is formed.

One end of the clasp 40 is fixed to the fixing groove 12 of the handrail frame 10, and the other end is protruded to the outside through the long groove 11 to be fixed to the rotation fixture 50.

The rotating fixture 50 is fixed to one end is fastened to the latch 40, the other end is pivotally coupled to the shaft hole 33 of the fixing bar (30).

The fixing bar connector 60 is a tube for maintaining a gap between the fixing bar 30 and the other fixing bar 30 of the upper and lower sides adjacent to, the coupling screw thread 32 of the fixing bar 30 on both inner circumference The inner thread portion 62 is screwed to the coupling ring 61 is formed, respectively, the adjacent coupling ring 61 is axially rotatably coupled by the connecting bar (63).

In the present invention as described above, the railing frame 10 is fixedly fixed by the fixing plate 20 at a predetermined interval in any stairs 70 whose lengths and widths of the stairs 70 are different. After fixing the other handrail frame 10 by the fixing plate 20 again, one side end and the other end of the fixing bar 30 is connected to the adjacent railing frame 10 by the fixed bar connector (60) pivotally It is possible to install the railing frame 10 more easily by fixing the rotatably connected by using the rotation fixture 50 and the fastener 40, respectively, because the material cost is further reduced because it is not installed in each step compartment. As a result, they will be able to play a more powerful and faithful role as railings.

As described above, the present invention is easy to apply to the stairs having various widths and inclinations so that the installation and maintenance of the railings are easy and the appearance is beautiful.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Of course, such changes will fall within the scope of the claims.
