The present invention relates to a building prefabricated staircase mounting structure, and more particularly, when constructing a stairway, which is a passage connecting each floor during construction of a building, the concrete is easily and quickly cured without using a separate stair formwork. It is to be constructed.

In general, a stairway, also called a stairway, refers to a short passageway connecting two floors of different heights, and as the city becomes more modern and higher, as in modern times, it has become indispensable in buildings. It is also an important element of design.

Stairs have a variety of structures and types of stairs, ranging from large ones for public use to small ones in a general house. Anyone with strong publicity should be able to climb up and down safely and comfortably. Although it may be subject to restrictions, it is also necessary to install the product so that it can be used as safely and comfortably as possible within the allowable range.For the dimensions such as the width and the height of the stairs and the width of the stepping foot, the type and size of the building It depends on the back.

Types of stairs include straight stairs, articulated stairs, hollow stairs, circular stairs, spiral stairs, etc. Depending on the shape, the most common are straight stairs that can safely climb up and down to a minimum area of stairs. , Fiberboard, synthetic resin, iron, stone, reinforced concrete, etc. In addition, when the height of the stairs is more than 3m, the landing is to be installed every 3m or less than 4m in height. All of the finishing work for prevention is done with safety in mind, and if there is no wall or the like on both sides of the stairs, fall prevention railings must be installed.

In order to construct the staircase as described above, after the stair formwork is installed, concrete is injected into the interior of the stair formwork, and when the injected concrete is hardened, the staircase is finally completed by removing the stair formwork and then installing a railing.

On the other hand, the stair formwork used in the prior art is a plywood (panel) and lumber in the form of a staircase to cut a plywood and lumber cut by a saw so as to have a certain width and length to produce a stair formwork by nailing one by one, concrete When injecting into the formwork, the concrete is injected through the wall formwork, and when the concrete is filled with the stair formwork and the wall formwork in order, the step form is removed and the concrete is solidified. You will finish your back.

However, in order to install the above-mentioned stair formwork, the sawdust and other wastes are generated by cutting the plywood and lumber to a certain width and length, so cleaning should be done, and the stair formwork should be installed by nailing nails one by one. It takes a lot of time and manpower to install the formwork, the concrete liquid flows out through the gap which is the connection part of the formwork and pollutes the surroundings, and there is a problem that the damage rate of the welded part of the panel corner increases due to the pressure of the concrete.

In addition, part of the stair formwork removed after the concrete is hardened or the nailed place will be damaged, so it is not suitable to take the used form to another construction site and use it again. The construction cost of manufacturing new stair formwork will be increased, and due to the unevenness of the finished staircase and the occurrence of staggering or fullness, it is necessary to break the part and rework the plastering which must be applied by mortar. In addition, since the Euroform of the wall formwork is installed in two stages on top of the stair formwork, the bending and flipping phenomenon occurs in the part where the upper and lower Euroforms are in contact with each other, resulting in the installation of horizontal and vertical reinforcement materials.

In addition, the step slab panel (= Eurofoam) is inefficient due to the combination of joists and strips on the plywood, and the work is inefficient. Since the corner portion is cured in an uneven state after construction because it is installed, there was a problem that must be finished again.

In addition, since a plurality of supports supporting the stair slab formwork are installed, there are many problems such as a safety accident when a worker or the like passes under the stair slab formwork.

Therefore, the present invention has been made to solve the above problems, when constructing a stairway, which is a passage connecting each floor during construction of the building, easy and fast in the state where the concrete is cured without using a separate stair formwork. The purpose of the present invention is not only to efficiently shorten the construction time by improving work efficiency, but also to provide a building assembly type stair mounting structure that can significantly reduce the construction cost of a building.
