The present invention relates to a method of construction of a building structure using steel and ALC block, in particular, the joint strength of the steel beams and beams, such as H beams and the joint strength of these and the ALC block and the improvement of tear strength, apparently The present invention relates to a method of constructing a building structure using steel and ALC blocks that can be constructed so that no sign of seam appears.

In building structures, the construction of concrete walls requires reinforcement work, reinforcement of formwork, concrete placement and curing, formwork demolition, and finishing, so the air is long and the cost of construction is increased.

In this respect, the construction method of A.L.C using construction method is more than the concrete construction method. This is because A.L.C blocks are packed with A.L.C mortar, so the air is short and construction costs are much lower. However, A.L.C is suitable for non-bearing walls, but there are limitations in applying it to building structures that use steel such as bearing walls and H-beams.

ALC and steel have different physical properties, so they are not bonded with ordinary cement mortar, and they cannot be finished smoothly and cleanly so that the seams between them are not visible. It was not a way to cope with defects such as cracks between columns, beams and ALC, cracks between ALC blocks, and discoloration. This was the main reason for having a lot of advantages but reluctant to build with steel and A.L.C blocks.

The present invention is to construct a steel column and beam steel frame and to build a wall by aligning the ALC block in the vertical space formed by the steel structure, to prevent the crack between the ALC block as well as the seam between the steel column and the beam and ALC block. Its main purpose is to provide a method of constructing a building structure using steel and ALC blocks that can be very effective and seemingly seam-free.

Columns and beams used in the present invention are H-beams, I-beams, U-shaped steels and the like. A.L.C blocks have a width that is comparable to, or slightly narrower than the space between the columns and beams. If the width of the A.L.C block is larger than the space, the part cut into the space is cut to the same width as the space, and if it is not available, the heat insulating material processed to fit the space is used.

Steel and A.L.C block have different affinity and have no affinity. In consideration of this, cracks are prevented by filling cores such as polyurethane foam having elasticity in their own spaces of steel.

In addition, brackets are to be attached to the column webs, if necessary, to further increase the adhesive strength of the A.L.C blocks or cores fitted in the steel columns and their spaces. The bracket is made of corrosion resistant steel plate and is L-shaped. The vertical part of the bracket is welded to the column web and the horizontal part is drilled into the nail hole to fix the A.L.C block or insulation by fixing nails, screws or bolts. Brackets are attached to every two or three layers of the A.L.C block.

The column is built on the anchor bolt embedded in the concrete foundation, and the nut is fastened to stabilize the steel beam between the adjacent columns. The lower layer of ALC block that touches the column and the concrete foundation is coated by applying ALC mortar on the bottom and the side facing the column, and the bracket of the ALC block that crawls under the horizontal part of the bracket and the space of the column Fix the nail into the nail hole.

In case of using heat insulating material, apply mortar (adhesive) to the side and bottom face of the column and insert it into the space of the column, and fix it by screwing the nail into the nail hole of the bracket.

After stacking A.L.C blocks at the bottom, stack up to beam as above.

If the A.L.C block is stacked, there is a joint seam between the pillar and the A.L.C block, the beam and the A.L.C block, and the A.L.C block. The seam may open or a step may occur. The seams and their steps must be removed in any way to ensure a smooth and neat appearance after finishing. However, there is no suitable finishing material that shows affinity for both steel and A.L.C blocks.

The present invention includes a column in which an ALC block abuts, a beam-column and a beam intersecting T, + in order to increase the adhesiveness and the adhesive strength of the plaster used as the finishing material. The base material is applied as a basic treatment for adhesion. Base material shall be primer.

The base material is applied to the outer surface of the wall including the ALC block and the column, the column and the beam intersecting in the T-shape or + -shape, or the inside and the outside, and then the mortar is coated on the surface of the base material, Lamination is carried out, and a mortar is applied to the surface of the glass fiber network to attach a metal or fiber net. Also, a mortar is applied to the surface of the net cloth to apply a finishing material. Finishing materials are plasters that are well known in the exterior field of architectural structures.

Finishing the outer wall in this way ensures that all seams and steps between the columns and beams, the columns and the A.L.C blocks, the beams and the A.L.C blocks, and even the A.L.C blocks are neatly hidden and have a flat outer surface, and this construction condition is stable over time.

Next, one preferred construction example will be given to help understand the present invention.
