The present invention relates to a prefabricated staircase installation structure for a multi-unit house, and more particularly, to minimize moving noise, to prevent the risk of injury due to corner collisions, to prevent slipping during movement, and to easily process wastewater when cleaning stairs. The present invention relates to a prefabricated staircase installation structure for apartment houses, in which a floor can be easily replaced periodically as needed, thereby greatly reducing maintenance costs.

A stair is a short passage that connects two floors of different heights, also called a stairway. As the city's three-dimensional and high-rise progress, such as modern times, it is indispensable in buildings, and it is an important element of architectural design in addition to its function as a passageway. In short, it is called a staircase, but there are various structures and forms, ranging from the large ones for public use to the small ones in a general house. The strong publicity must be safe and comfortable for anyone to climb up and down. This may be restricted by area or cost, but it also needs to be installed to be as safe and comfortable as possible within the allowable range.

These types of stairs include straight stairs, refractive stairs, hollow stairs, circular stairs, and spiral stairs (extreme forms of circular stairs), the most common being straight stairs. It is a form that can be safely climbed up and down. Materials used are various, such as wood, fiberboard, synthetic resin, iron, stone, reinforced concrete. In addition, when the height of the stairs is more than 3m, it is prescribed by law to install the landings every 3m or less or 4m or less. This is not only a resting part but also a necessary part for safety of use, and there are also regulations in the Building Code regarding its location and width. In addition, the finishing work for the installation of railings or the prevention of slipping of the tread surface is also performed in consideration of safety. If there are no walls or the like on both sides of the stairs, railings must be installed. In addition, when a slippery material is used as a stepping material for convenience of cleaning or for other reasons, a groove should be dug in the wooden stepping board, and when a metal or synthetic resin product is used, a non-slip, a rug, or a rubber rug should be laid.

In the past, stairs have been constructed so that pedestrians can move up and down conveniently in the upper and lower connecting passages of buildings or slope sections of the outdoors, and most of these stairs have been constructed by using the site concrete pouring method.

When explaining the process of constructing a staircase in the connecting passage of the upper and lower floors of the building as an on-site concrete pouring method as an example, assembling and installing the formwork panels for the bottom and both ends inclined at the corresponding position, formwork panels for the floor and both ends After reinforcing the rebars vertically and horizontally on the upper part, the formwork panel for stepping is installed so as to stand and be fixed vertically at equal intervals of the formwork panel for both ends, and uncured inside the formwork panel for bottom and both ends and stepping panels. The concrete is poured and cured, thereby constructing a staircase with stepping steps integrally on top of the sloped floor.

In this way, the staircase constructed by the site concrete pouring method has a very structurally strong advantage because the sloped floor and the stepping are integrally formed, but in the point of constructing the sloped floor and the stepping as the concrete as the site concrete, On the outer surface of the stepping step of the step where the rough surface is made by pouring unhardened concrete, attaching a smooth marble plate separately or plastering with mixed mortar (mixture of white cement and crushed stone) and smoothly polishing the hardened surface. Since the subsequent finishing process such as additionally performed, there is a problem that the construction period is extended and the construction cost is excessively consumed, resulting in the loss of constructability and economics due to the construction of the stairs.

In addition, when moving up and down the stairs, the movement noise is severe, sharp corners when children or adults slip accidentally, there is a lot of injury of bruises and fractures, there was a structural problem that is not good drainage when cleaning.

The present invention is to solve the above problems, to minimize the moving noise, to prevent the risk of injury due to the corner collision, to prevent slipping during movement, to facilitate the drainage of sewage when cleaning the stairs, the floor periodically The purpose is to provide a prefabricated staircase installation structure for apartment houses that can be easily replaced as needed as the maintenance cost is greatly reduced.

In order to achieve the above object, the present invention is formed to be inclined from the upper left to the lower left, the upper and lower ends are respectively fastened horizontally to the right and left by fastening pins to the upper horizontal plate and the lower horizontal plate to form a step, respectively It is fixed to form a horizontal plane, the bottom and the bottom of the bottom is formed with a fastening groove for inserting a plurality of fastening pins, respectively, a plurality of fastening bolt holes are formed on the left end of the top surface, the inclined upper surface inward arc-shaped Support recesses are continuously formed, and the left and right ends of the support recesses are prefabricated stair blocks each having a vertical bolt;

The upper end is formed with a handle bar having a plurality of bolt holes fastened in the same diagonal direction as the inclined surface of the prefabricated staircase block, fastened by the fastening bolt, the center side is vertically upright, the bottom is bent perpendicularly to the inclined surface, the center of the It is formed with a fastening hole and the outer surface is spaced apart from the fastening hole and the support bolt is formed protruding, the lower end of the stair railing frame is fastened to the fixed bolt of the prefabricated staircase block;

A non-slip rubber frame is formed with a cross-shaped body having a cross-shaped body, with shaft bolts protruding from the centers of both sides of the body, and inserting recesses formed at the upper, lower, left, and right ends of the body, respectively. The fastening hole is formed, and a fastening hole is formed between the shaft bolt and the insertion recess. The fastening hole of the upper side of the anti-rotation fastening frame having a "ㅓ" shape is fastened and fastened to the fastening hole, and the shaft bolt is inserted into the fastening hole of the stair railing frame. In the state, the lower fixing hole of the rotating front fastening frame is fastened and fixed, the left fixing hole for the anti-rotation fastening frame is cross-shaped staircase that is fastened and fixed to the support bolt;

The bottom of the cross-shaped staircase is located in the lower front side of the cross-shaped staircase to support the bottom surface of the cross-shaped staircase from the bottom of the prefabricated stair block, while supporting and supporting the front panel by the fastening nut to fasten the lower part A support jack having a fastening screw that covers;

Box-shaped seated on the upper right side of the top of the cross-shaped staircase of the cross-shaped staircase, the top of the lid is opened and closed by a hinge, the top of the lid is fastened to the top bolt fastening bolt hole of the prefabricated staircase block The fixing bolt hole is formed, the lower surface of the cap portion is characterized in that the foreign material inlet groove is formed inward to have a foreign matter collection box for storing the inflow of dust or water.

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