Description
The present invention relates to a prefabricated joint structure of the column-beam connection of the steel structure using a circular steel pipe and a construction method of the steel structure using the same.
More specifically, the present invention relates to a method of constructing a connection between a pillar and a beam in a steel frame structure using a circular steel pipe member by integrally connecting the pillar member and the beam member in the field.
The present invention can standardize the manufacturing process by modularizing the prefabricated joining structure of the column-beam joint of the same shape and factory production. Possible and easy disassembly of the pre-assembled state has the advantage.
In addition, the present invention is to propose a method of manufacturing and constructing a steel frame structure capable of optimal design of the pillar member, beam member and brace member.
Steel structures in buildings or high-rise apartments have the advantage of increasing the space between pillars compared to concrete structures, thus making the plan more flexible and reducing the area of the pillars. In addition, the material itself can be recycled, making it more environmentally friendly than concrete structures.
In addition, the construction period is shorter than the concrete structure, which is an advantageous structural form for the project operator.
However, the steel structure has the disadvantage that the material is expensive and the tight finish of the member is difficult, so more economical design and improvement of construction technology are required.
The pillars and beams of steel structures of conventional buildings and apartments are mainly composed of H-beams, and in high-rise buildings, the box sections are made of sheet material when it is difficult to construct the pillar sections with only H-beams.
However, the section steel has a directional cross section, and as a result, a section axis is formed between the steel shaft and the weak shaft, thereby deterring the economic design of the steel structure. In addition, the pillars of the box section made of plate have disadvantages in that the cross section is large in terms of plan planning, and the steel frame manufacturing cost increases due to the box section production.
1 shows a column-beam connection structure in a steel structure made of a section steel.
When the column is composed of section steel beams connected to the column can be configured only at right angles or horizontally, it is difficult to apply in buildings or apartments having a tower-type plane, there is a disadvantage that can not increase the length of the beam supporting the weak axis.
Figure 2 shows the connection details of the beam connected to the column consisting of the box section.
In this case, as in the case of pillars made of section steel, the cross sections are directional, so the beams connected to the pillars must be arranged at right angles or horizontal directions, and internal reinforcement is required to resist the concentrated reaction and moment of the beams inside the box. This is difficult and there is a problem of rising manufacturing cost, the box section is large, there is a disadvantage that the effective floor area of the building is small.
The present invention is to make the construction of the steel structure efficiently and economically by making the connection of the column-beam joint and the beam and the longitudinal beams supported on the beam in an integral structure in the steel structure consisting of a circular steel pipe to facilitate the assembly of the joint First purpose,
The second purpose is to overcome the inefficient section performance of section steel and the limitations of building plan by introducing circular steel tube members into steel structure.
The third purpose is to present a way to reinforce the structural weakness of the existing column-beam connection.
The fourth objective is to provide economical design and construction by suggesting a cross-sectional reinforcement plan to improve the structural performance of steel members.
The present invention is to produce a column-beam joint in a prefabricated joint structure in the steel frame structure consisting of a circular steel pipe, to propose a connection method of the column member and the beam member connected to the integrally manufactured joint.
As shown in Fig. 3, the prefabricated joint structure of the column-beam connection is manufactured by directly welding the beam connector to a circular steel tube having the same thickness and outer diameter as the column section. At this time, the height of the prefabricated joint structure of the column-beam connection is 4cm to 20cm larger than the outer diameter of the beam, and the length of the beam connector is 0.2 to 0.3 times the length of the beam span. Fill the non-shrinkable concrete so that the prefabricated joint structure of the column-beam connection does not cause local deformation due to the parent moment reaction of the beam connector.
The length of the beam connector should be 0.2 to 0.3 times the length of the beam length because at this point the bending moment due to the bottom plate load of the beam member will be zero. In the beam connector of the prefabricated structure of column-beam connection, the parent moment is generated larger than the maximum static moment occurring at the center of the beam. The maximum flexural stress at the beam connector generated by this parent moment can be effectively reduced by introducing prestressing at the upper edge side of the beam connector.
The steel wire for introducing prestressing is installed through the column steel pipe of the prefabricated structure of the column-beam connection inside the beam connector to be filled with non-concrete concrete as shown in FIG. In the spaced apart from the neutral axis by 0.2D to 0.3D upwards.
After the steel wire is installed, non-shrink concrete is tightly packed and prestressing is introduced in a pretension manner when sufficient strength of the non-shrink concrete is developed.
As shown in FIG. 4, the method of filling the inside of the cross section of the beam connector with non-contraction concrete may be unreasonable due to an increase in the fixed load in some cases. As an alternative to this, as shown in Fig. 5, only the upper end of the beam connector neutral shaft is filled with non-condensed concrete to reduce the fixed load, and at the same time, a facility and a distribution system for water supply and heating may be installed in the inner space of the beam.
The prefabricated joining structure of the column-beam connection and the column member, and the connection method of the column-beam connection and the beam member can be used in combination.
As shown in FIG. 6, a ring having an outer diameter equal to the inner diameter of the pillar is installed to protrude out of the pillar connecting portion in the pillar connector of the pillar-beam connection assembly assembly structure. At this time, the ring installed inside the cutting process a part so that the protrusion is equal to the taper to induce a smooth insertion when connecting the pillar member. At this time, the end of the column connector and the end of the pillar member to be connected thereto are assembled after performing the improvement process for the butt welding in advance. In addition, since the ring installed inside serves as a backing plate for butt welding, high quality welding without error is possible.
Column-beam connection The connection of the beam connector and the beam of the prefabricated joint structure cannot introduce the same method as in FIG. This is because the distance between the ends of the column connecting portions at both ends to which the beam is to be connected is almost the same as the length of the beam member, so that the assembly of the type as shown in FIG. 6 is impossible. Therefore, the beam connector and the beam as shown in Figure 7, the production of the connecting ring in the interior of the beam in advance to install. This connection ring is not fixed to a fixed position like a ring when the column is connected, but is foldable in contact with the inner diameter of the beam.
The left and right movement of the connection ring is performed by the operation of the work tool inserted into the connection ring work hole. If the width of the connecting ring is 2S, the inner side of the beam member is moved by S toward the beam connector.
The beam member is supported by the connecting ring protruding by S. Welding is performed in this state supported by the connection ring. In this case, because the connecting ring acts as a backing material when the beam connector is connected to the butt joint, high quality welding is possible without the possibility of error. Of course, the ends of the beam connector and both ends of the beam performs an improved machining using a cutting machine in the manufacturing process.
조립 The prefabricated joint structure of the column-beam joint in the steel frame structure made of the circular steel pipe of the present invention is simple in structure itself and stiffness at the joint is excellent structural stability compared to the prior art.
용접 Since the welding is possible in the assembled state, the welding is precise, so that the quality of the entire frame structure as well as the quality of the welding is formed.
원형 When applying the present invention, the circular steel pipe column has a small cross-sectional dimension, thereby increasing the effective cross-sectional area of the building.
⒟ The circular steel pipe member has no directivity in cross section, so it has excellent applicability not only to buildings with rectangular floor sections but also to frameworks with irregular floor sections such as tower apartments.
기둥 The pillar member having the section steel section is not preferable to be exposed to the exterior of the aesthetic appearance, but the circular steel tube pillar member has the effect of enhancing the aesthetics of the building when exposed to the exterior.
공장 The manufacturing process can be standardized by modularizing the prefabricated joint structure of the column-beam joint of the same shape, and the pre-assembly of certain blocks in the factory and through this, it is possible to check and correct whether the members are manufactured within tolerance. It is easy to disassemble the provisional state and has excellent field applicability.
