Description
본 발명은 가설 철골 기둥(200)을 이용한 합성보(100) 시공방법에 관한 것으로, 더욱 상세하게는 가설 철골 기둥(200)은 2개, 4개로 이루어진 형태이고, 이를 이용하여 H형강 2개를 평행하게 배치하여, 중간부분에 콘크리트을 충진하여 합성보(100)로 만드는 시공방법에 관한 것이다.
[0001] The present invention relates to a method of constructing a composite beam 100 using a hypothetical steel column 200, more specifically, a hypothetical steel column 200 of two or four columns, And filling the concrete with concrete in the middle part thereof to make the composite sheet 100. [
현재, 일반적인 구조형태는 철골 기둥 + 철골보 형태로 이루어져 있어, 철골보는 기둥과 기둥의 사이인 경간에 따라 부재 크기가 결정되고 있다. 부재의 크기를 결정하는 구조설계 식은 단순보일 경우, 일반적으로 M=wL^2/8로 결정된다. 경간인 L의 제곱승에 의해 부재 크기가 결정되므로, 경간이 긴 경우 부재가 상당히 커짐에 따라 철골보를 효과적으로 시공할 수 있는 대안이 필요한 상태이다.At present, the general structural form is composed of steel column + steel beam, and the steel beam is determined according to the span between the column and the column. If the structural design equation that determines the size of the member is simple, it is generally determined as M = wL ^ 2/8. Since the member size is determined by the square power of the span L, when the span is long, the member becomes considerably large, and an alternative method for effectively constructing the steel beam is needed.
또한, 철골기둥 표면에 콘크리트를 추가 시공하여 철골철근콘크리트구조가 되는데, 철골 기둥은 고가인 단점을 가진다. 따라서, 경제성을 고려하여 기둥 중앙부에 들어가는 철골 부재 없이 기둥을 시공 할 수 있는 방법이 필요하다.In addition, concrete is added to the surface of the steel column to form a steel-reinforced concrete structure. The steel column has a disadvantage of being expensive. Therefore, considering the economical efficiency, there is a need for a method of constructing a column without a steel frame member entering the center of the column.
전술한 문제점을 해결하기 위하여 본 발명이 이루고자 하는 기술적 과제는, 경간을 줄일 수 있는 합성보(100) 시공 방법과, 가설 철골 기둥(200)을 이용하여 철골 기둥 없이 기둥을 시공 할 수 있는 시공 방법을 제시하는데 있다.
SUMMARY OF THE INVENTION In order to solve the above-described problems, the present invention provides a method of constructing a composite beam (100) capable of reducing a span and a method of constructing a column without columnar columns using a columnar steel column (200) To be presented.
전술한 기술적 과제를 해결하기 위한 수단으로서, 경간을 줄이기 위해서 H형강 2개를 일정간격을 두고 평행하게 배치하여 중앙부에 콘크리트 충진하여 합성보(100)로 시공한다. 이 때 합성보(100)는 폭이 넓은 WIDE BEAM으로 시공되어 경간을 줄이는 효과를 가지게 된다. As means for solving the above-mentioned technical problem, two H-shaped beams are arranged parallel to each other at regular intervals in order to reduce the span, and the concrete is filled in the central part to construct the composite beam. At this time, the composite beam 100 is constructed as a wide beam, thereby reducing the span.
상기 합성보(100)를 시공하는 과정에서, 가설 철골 기둥(200) 2개 및 4개 철골보로 연결하여 H형으로 만들어, 합성보(100)의 시공성을 용이하게 할 수 있다.
In the process of constructing the composite beam 100, two steel columns 200 and four steel beams are connected to form an H-shape, thereby facilitating the workability of the composite beam 100.
본 발생의 합성보(100)는 폭이 넓은 WIDE BEAM으로 시공되어 경간이 줄어들어, 중간 보부재가 작아져, 층고 절감과 경제성이 향상되는 효과가 발생된다.The composite beam 100 of the present occurrence is constructed by a wide beam BEAM so that the span is reduced and the intermediate beam member becomes smaller, thereby reducing the height of the beam and improving the economical efficiency.
또한, 합성보(100) 시공을 위한 가설 철골 기둥(200)의 중앙부나 옆으로 콘크리트 기둥을 시공할 수 있어, 가설 철골 기둥(200)은 해체하여 재사용 할 수 있어 경제성이 향샹된다.
Also, since the concrete column can be installed at the center portion or the side of the temporary steel column 200 for constructing the composite beam 100, the temporary steel column 200 can be disassembled and reused, thereby improving the economical efficiency.
