Description

Steel frame for building construction and construction method using the same {Steel frame for structure operation and method for structure operation by using a steel frame}

The present invention relates to a steel frame that is installed as a skeleton of a concrete building and a building construction method using the same, more specifically, the "c" section of the steel frame to be installed as a skeleton of the building by easily assembling the horizontal and vertical lattice type It is to provide a building construction steel frame and a building construction method using the same, so that the internal / exterior materials and formwork plate material can be easily attached and detached on the inside / outside of the steel frame.

In general, the concrete filled during building construction has a large compressive strength, but in itself, there is a weak point to the tensile and shear loads, so the steel frame (STEEL HOUSE) is installed as a supplement to the skeleton, the steel frame is earthquake or outside It plays an important role in safeguarding the building from vibrations.

In addition, when the steel frame construction for the construction of concrete buildings, the reinforcement work is arranged by vertically and horizontally arranging reinforcing bars, section steel, beams, etc. on the site where the outer wall and the inner wall are to be installed, and then the internal and external formwork is installed on both sides of the installed reinforcement bars. After the installation of the raw concrete is poured, after the completion of the curing of the poured concrete, the slab reinforcing bar is placed on the upper side again, the formwork is installed, and the concrete is poured to form the slab. When the construction was completed, the formwork was demolished, the insulation construction and the interior and exterior materials were in order.

The internal and external formwork was to be supported by standing up on each other to the outside surface or to maintain the formwork is installed by using a gap holder.

However, when using the shoring to maintain the installation of the formwork, the hassle and difficulty of dismantling work need to be nailed one by one, and when using the spacing area, the inside and outside formwork is mainly penetrated by the spacing area. The fastening work was cumbersome and took a long time, so it took a long time to install the formwork.

In addition, after the entrance wall and slab are completely cured with concrete, the interior and exterior formwork installed as above should be dismantled.In this case, the formwork and spacing area must be removed first, and then the formwork must be dismantled. Labor costs are considerable, and the subsidiary materials costs due to the formwork, shoring, spacing, etc. above account for a large part of the construction costs, and the rising cost of construction costs cannot be ignored.

In addition, in the related art, after the inner and outer walls and the slab construction work as described above, the insulation work is installed separately from the inner wall of the outer wall, and the inner and outer materials are stacked. Thus, the inner and outer walls and the slab are constructed. If the work and insulation construction and the internal and external construction work cannot be performed together, and the construction is performed separately, there is a problem in that the construction cost is increased due to the considerably long construction period and the high labor cost.

The present invention has been developed in order to solve the conventional problems as described above, the object of the present invention is to provide a steel frame that is easy to install and yet firmly installed construction.

Another object of the present invention is to perform the concrete placing process of the slab and the wall at the same time attached to the interior / exterior materials and formwork plate attached to the inside / outside of the steel frame, so that the effect of shortening the air and reducing the construction cost in a simple process It is to provide a building construction method using the steel frame for building construction can be achieved.
