Description

Composite beam structure {Hybrid Beam Structure}

The present invention relates to a composite beam structure, and more particularly to a composite beam structure in which a conventional wooden beam structure is realized by a composite structure of wood and steel.

Steel house (STEEL FRAMED HOUSE) is a new structural type house replacing existing masonry or wooden house. Instead of wood, 1mm thick galvanized steel sheet is used as main structural material, And the panels are assembled by standing on the site. The joints are also similar to the construction method of wood as a structure which is screwed using tapping screws using a conventional screw instead of welding which is mainly used in existing steel structures have.

The main structural material of the steel house is made of hot-dip galvanized steel, which is excellent in durability and strength. It has excellent corrosion resistance and is not rotten or twisted. It has a long lifetime and flexible structure.

In addition, since the wall thickness is thinner than conventional concrete and brick houses, the efficiency of space is high and the weight of members is light, so that it is easy to construct and the defect occurrence rate is small. Also, it is possible to manufacture electric pipelines and facility piping in advance by standardization. This is simple.

On the other hand, the wood is used only for the area directly contacted with the forest, and unlike the wooden house, all of the structural materials can be recycled, and thus it is widely used because it can minimize the damage of nature due to logging or aggregate collection.

However, the conventional steel house as described above is simpler in process and easier to install than a wooden or masonry tank. However, since the outer wall, the inner wall, the floor, and the roof structural members are made of a plurality of auxiliary materials such as wooden houses, The air was delayed and the reinforcement ribs were not formed in the auxiliary material, so that there was a limit in strength, and there was a problem that the quality of the house deteriorated and the construction cost was increased due to the air delay.

Korean Unexamined Patent Publication No. 2000-0072129 (December 2000) enhances the strength of a truss structure of a wall or a roof subjected to a vertical load, and simplifies the structure of a panel, a roof and a floor, thereby improving air shortening and quality of a house Steel houses which can improve the durability and reliability of the products due to long use of time or distortion of auxiliary materials due to external impact or load are described. The roofs formed by edges, upper and lower trusses, ridges and perlin A steel house comprising a wall which is filled with a heat insulating material inside and which is formed by a structural plywood on the outer side and which is fixed to a track by a top and a bottom and a floor which is formed by a rim track and a joist, The upper and lower trusses are folded into a large size so that the side and both sides are formed and the lower side is opened. And the wall is formed as a 'U' shaped steel so as to form a groove as a stiffener at the center, and the upper track is formed as an upper track, and the structural plywood is coupled with a lapping screw to form a panel And a column having a plurality of reinforcing ribs formed outside thereof is inserted into the 'C' -shaped steel of the connecting portion of the panel, and the panel connecting member is connected to the inside of the 'C' shaped steel pipe at the corner of the panel, The upper and lower corner tracks are formed in a manner that the other side of the open side of the joist is in surface contact with the other side of the joist, and between the joists, a central portion of one side And an open blocking is interposed. According to the described technique, the structure of the truss structure of a wall or roof subjected to a vertical load and the structure of a floor load receiving a horizontal load are reinforced to increase the strength and simplify the structure, thereby improving the air shortening and the quality of the house. Can be improved.

Korean Patent No. 10-1383314 (Apr. 04, 2014) discloses a method in which a plurality of posts are stood up by hitting the posts on a slope or a slope of a road, and adjacent posts are connected by an "X" Which is capable of increasing the durability by preventing settlement and deformation of the post due to soil damage and collapse due to the increase of the bearing capacity between the bridge and the bridge. According to the disclosed technology, there are provided a plurality of posts which are vertically struck by a hammers in the ground surface of a road or on the slope of the road and are installed at regular intervals, and a support bar connected to the posts in an "X" A main bridge which is installed on the upper part of the support frame and which is installed in the longitudinal direction and a bridge which is installed on the upper part of the main beam and in which any one of concrete or elastic packing is installed to constitute a bottom surface, And a height regulating means provided between the support frame and the height adjusting means for adjusting the height of the support frame, the post including an inner post adjacent to the barrier seats of the road and an outer post spaced apart from the inner post by a certain distance, And the support bars are arranged at the top and bottom And the brackets are connected to the brackets in the form of an "X ", wherein the support frame is formed in the shape of a square tube, and the entire length thereof is divided into two parts, And a length of the insertion portion is varied according to a distance of the post formed by being fitted to the end portion of the divided side of the insertion portion. A floor member having a holder portion and a flange portion formed on both side portions thereof and having a rubber pad attached to a bottom portion of the bottom portion supported by the main beam and a bottom portion protruding from the bottom portion at a predetermined interval between the holder portion and the flange portion, A rib having a protrusion and a floor formed by placing a concrete or an elastic packing material on the floor Wherein the height adjusting means comprises: a stopper coupled to an upper portion of the post, a hole formed at a central portion thereof, a cap having a fastening nut attached thereto, a screw head screwed to the fastening nut, And a flat plate attached to an upper portion of the holder and attached to a bottom surface of the support frame. The fastening bolt includes a fastening bolt having a rectangular fastening portion at the bottom thereof, a holder to which the head portion of the fastening bolt is rotatably fitted.

The conventional beam structure as described above has a disadvantage in that it is structurally unstable and has to depend on the design due to experience, although the wood is generally used as the main material and it is easy to process and lightweight.
