Description

Joining Steel Structure and Korean Style Building Thereby {Joint of Steel Structure and Korean Style Building Thereby}

The present invention relates to a steel-type steel structure assembly structure of the steel frame and Korean architecture applied to the same, more specifically, a new way of assembling by assembling or joining each other between the steel member processing the nib, jaw, groove or hole The steel frame assembly structure and relates to a Korean building to be preferably applied to complete.

Korean architecture according to Korean traditional architecture follows the structure of natural wood. In other words, traditional Korean buildings are built while lumbering, timbering and assembling natural wood. However, traditional Korean buildings deal with natural wood depending on manpower, so it takes a considerable amount of construction products and a long construction period, and the cost of construction is also high due to the use of expensive natural wood. In addition, the traditional Korean building has a structural disadvantage that the distortion deformation occurs largely because the natural wood has a large shrinkage expansion by wet and dry.

In order to improve the above disadvantages, the present inventors have developed a Korean-style building that embodies the exterior of a traditional Korean-style building while completing a frame with steel frame, and has been patented by Patent No. 10-0934458. In Patent No. 10-0934458, a Korean-style building is constructed in such a manner as to form a basic skeleton with steel frame and add a finish wood as shown in FIG. However, Patent No. 10-0934458 performs the joining of steel members to each other by welding or bolting like a normal steel frame, and this joining method is not only troublesome, but also has a problem that requires a lot of construction products such as difficulty in accurately positioning the joints. have.

The present invention has been developed to improve the problem of deterioration of construction ability according to the conventional steel joining method, and a new type of assembly structure for assembling by assembling or joining each other between the steel member processing the nib, jaw, groove or hole It relates to a Korean building to be preferably applied to complete.

In order to solve the above technical problem, the present invention in the assembly structure by the steel member, the nib, jaw, groove or hole is processed in the steel member to be matched or jointed by the nib, jaw, groove or hole between the steel members Provides a caustic steel frame assembly structure characterized in that the assembly.

In another aspect, the present invention is a Korean-style building with a steel structure assembly structure, the lower frame is composed of a hollow steel frame assembly structure between the pillar member and the purlin member and the beam member, and the anti-corrugated steel frame between the anti-air member, the bell beam member, the middle purlin member By constructing the upper frame as an assembly structure to be installed on top of the lower frame, and provides a Korean-style building by the steel-type steel assembly structure, characterized in that the outer frame and the shell of the upper frame surrounding the wood finishing material.

According to the present invention, the following effects can be expected.

First, since the steel members are assembled with each other in the form of chin, tactile fit, etc., the assembly work can be performed quickly and accurately. In particular, because the jaw, nib, hole, etc. can be precisely processed at the factory to make parts, it is possible to improve the construction quality of the joints between steel members with simple custom assembly work in the field, as well as reduce the construction products.

Second, while adopting modern building materials such as steel frame, it is possible to easily build Korean-style buildings while reproducing the traditional wooden joining method. In addition, since the Korean-style building is constructed by fixing the wooden finishing material on the frame after the construction of the frame part, it is possible to secure the construction of the Korean-style building and the appearance of the traditional building at the same time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings and preferred embodiments.

The present invention relates to an assembly structure by a steel member, by processing the tip (T), jaw (C), grooves (G) or holes (CH, TH) in the steel member to the steel member (T), jaw It is characterized by assembling by joining or joining by (C), groove G or holes CH and TH. Unlike conventionally assembled by welding or bolt-joining each other between the steel frame members, the old method used in the wooden structure such as Korean traditional buildings is introduced to the steel frame joint. In order to introduce the method to the steel frame, steel (T), jaw (C), grooves (G), holes (CH, TH) and the like are processed in the steel frame, which can be easily formed through laser processing. Furthermore, after assembling the steel members together, the joints may be additionally supplemented by welding or bolting. 2 to 7 in addition to the nib (T), jaw (C), grooves (G), holes (CH, TH) for assembling the joints between the steel members can be seen that the bolt hole (BH) is further processed. Bolt hole (BH) is to supplement the steel frame members with a bolted joint or to bolt the finishing plate, such as wood finishing material to the steel member.

Figures 2 to 7 are various examples for the details of the joints of the columns and beams in the fastening steel frame assembly structure according to the present invention, Figure 8 is a Korean-style building completed by applying the fastening steel frame assembly structure of Figures 2 to 7 It is an example.
