Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hybrid type structure member, a manufacturing method thereof, and a frame system using the hybrid type structure member,

The present invention relates to a hybrid type structural member and a frame system using the hybrid type structural member, and more particularly, to a hybrid type structural member including three types of structural materials such as wood, steel, and concrete in the field of synthetic structural technology, Frame system.

Neck structure is an ecological architecture, which is a good structure that combines the effect of interior and exterior materials with natural beauty and unique texture of wood. In addition, it has advantages of weight reduction of buildings and shortening of air.

On the other hand, wood has weaker strength and durability than steel and concrete due to its material properties. In addition, when natural wood is processed and used, the length and thickness of the material are limited, and shrinkage and twisting occur in the process of drying the wood. Due to the material properties of these timber, the tree structure has been applied to buildings with short spans and low stories.

However, the development of wood structures such as orthogonal laminated timber (CLT) and hybrid technology, which have recently increased in strength, is actively underway, and many countries are easing regulations on wooden building floors in response to climate change policy. The EU countries, the United States and Canada are actively promoting policies to encourage wooden architecture. In Japan, where the proportion of wooden houses is 50%, the government has introduced policies to convert all low-rise public buildings into wooden houses.

(Hereinafter referred to as "Prior Art 1") and Registered Patent No. 10-0010324 (hereinafter referred to as "Prior Art 2") as a method of reinforcing a conventional wooden structural member, for example, in Korean Registered Utility Model No. 20-0359033 . 1 and 2, respectively.

As shown in FIG. 1, in the prior art 1, grooves are formed on the outer surface of the wooden structural member 10 such that the reinforcing member 11 can be inserted in the lengthwise direction, the epoxy adhesive 13 is first applied to the grooves, (11) is inserted and fixed, and the cavity (13) is filled with the groove to which the reinforcing metal is fixed to complete the groove, and the finish is finished with the finish material (15). This method has the advantage that it can easily reinforce the wood by using reinforced steel.

However, the bending tensile stiffener should be sufficiently fixed for bending resistance and structural safety in beam members subjected to bending moment. However, in the case of Prior Art 1, there is a problem that since the reinforcing material is only bonded to the wood and is not fixed, though it is reinforced on the cross section, the reinforcing ability against the bending tensile force and the structural safety can not be secured. In addition, as the strength against bending moment increases due to this reinforcement, the shear force increases accordingly. There is no reinforcement measure for the increased shear force, and the method of forming a frame in which beam and column are combined is not proposed.

As shown in FIG. 2, the hybrid wood structural member manufacturing method according to the prior art 2 is a method in which a composite wood material 25 processed around a steel member 20 of a steel structure frame is adhered and fixed, It is a method that can be used as a role of fireproof cover.

For the sake of convenience, the thicknesses and dimensions of the structures shown in the drawings may be exaggerated, and they do not mean that the dimensions and the proportions of the structures should be actually set.

3 to 5, a column member and a beam member according to an embodiment of the present invention will be described. FIG. 3 is an exploded perspective view of a specific portion of a beam member according to an embodiment of the present invention, FIG. 4 is a perspective view showing a cross section of the beam member of FIG. 3, Fig. 3 is a perspective view schematically showing a member and a beam member. Fig.

The column member and the beam member according to the present embodiment may differ in terms of the reference cross-sectional aspect ratio in the width direction and the method of filling the fillers on the inner side. Hereinafter, for the sake of convenience of description, the description of the detailed configuration of the column member 101 will be omitted as a description of the configuration of the beam member 102. [

As shown in FIG. 3, the beam member 102 includes a steel pipe stiffener 120 and a neck member 150. The steel pipe stiffener 120 has a rectangular cross-sectional shape, is formed to have a predetermined length, and is formed in the shape of a rectangular pipe whose inside passes through in the direction of the central axis. The steel pipe stiffener 120 is formed of a steel material and functions as a stiffener in the hybrid neck structure member according to the present embodiment.

The neck member 150 is formed in a "C" shape like a half-folded wood pipe that surrounds the outside of the steel pipe stiffener 120 described above. Specifically, the nacelle 150 is formed in a bent shape at the upper and lower ends of one side of the steel pipe stiffener 120. That is, the neck member 150 is formed with bent portions 151 that are bent in the vertical direction at the upper and lower ends. The bent end portion 1511 of one of the nacelle members 150 is brought into contact with the bent end portion 1511 of the other nacelle member 150 when the steel pipe stiffener 120 and the pair of nacelle members 150 are assembled. The inner side of the nacelle 150 is formed to match the contour of the steel pipe stiffener 120. However, the outer shape of the nacelle 150 according to the present embodiment is formed in a square pillar shape when coupled with the steel pipe stiffener 120, but it is not limited thereto and can be variously formed according to the purpose of the interior such as the interior.

It is preferable to apply an adhesive (adh) to the inside of the nacelle 150 at the time of assembling the steel pipe stiffener 120 and the nacelle 150. For example, an epoxy adhesive (adh) can be applied to the surface contacting the steel pipe stiffener 120 and the end surface 1511 of the bent portion. At this time, as the epoxy adhesive, a resilient epoxy adhesive having ARALDITE AV138M-1 as a base and HV998 as a curing agent can be used.

The first fastening member 190 is fastened so as to penetrate and fix the pair of the neck members 150 and the steel pipe stiffener 120. As the first fastening member 190, for example, a high tension bolt can be used.

The through holes 153 formed in the steel pipe reinforcing member 120 and the neck member 150 may be formed in advance in order to fasten the first fastening member 190. In order to reduce errors in assembling, It is also possible to process.

The receiving groove 1531 may be formed at the outer side of the through hole 153 formed in the nacelle 150. When the high-tension bolt or the like is used as the first fastening member 190, the receiving groove 1531 functions to accommodate the head or the nut 193 of the high-tension bolt so as not to be exposed to the outside.

At this time, unlike the case of the column member 101 shown in FIG. 5 (a), in case of the beam member 102 shown in FIG. 5 (b), in the process of forming the frame structure, It is also possible to fill the filler only in the inner portion 125 of the remaining portion of the steel tube stiffener 120 excluding both ends thereof so that the filler charged inside can be introduced. The related structure will be described later in detail.

The filler (C1) can improve the synthetic effect and the structural safety performance. Further, in the case of the column member (101), the upper and lower columns are assembled and then the concrete or mortar is filled in the steel pipe stiffener (110) So that the integrity of the column can be improved.

On the other hand, the pillar member 101 or the pillar member 102 can be manufactured to be modularized for ease of field installation. For example, when it is determined that concrete or mortar is to be charged into the steel pipe stiffener 110 of the beam member at the design stage, the beam member 102 is filled with concrete or mortar in advance, and is manufactured as a composite member in advance. In the state in which the concrete or the mortar is not filled in the column member 101, it is possible to combine the beams in four directions at the time of field construction, and then fill the filling material (concrete or mortar) through the upper column member 101 .

On the other hand, a method of modularly assembling both the pillar member 101 or the beam member 102 is also possible.

5 (a), the column member 101 includes an inner steel pipe reinforcing member 110 and an outer wooden structural member 150. As described above, There is no significant difference from the shape of the beam member 102 except for the difference in the filling method of the filler.

The column member 101 and the beam member 102 are formed such that the steel tube stiffeners 115 and 125 are exposed to the outside at both ends thereof. The steel pipe reinforcing members 115 and 125 exposed to the outside form a fastening structure with other components in the process of forming the frame structure thereafter.

As shown in FIG. 7, the column fastening part 210a of the connection part 200a may further include a filler outlet 215 so as to communicate the column fastening part 210a and the beam fastening part 220. As shown in FIG. When the filler is filled in the column member after the formation process of the frame structure or the frame structure, the filler may be introduced into the filler member through the filler outlet 215.

That is, when the rigidity of the frame joint is required to be greater, the concrete or mortar filled in the column member flows over the connection portion of the beam member to be filled, so that the frame joint can be integrated with the concrete or the mortar in a bidirectional cross shape.

Meanwhile, the connecting part according to the present embodiment can be modified into various forms. For example, in the case of the connecting portion 200b provided at the outer portion of the wooden structure, it is also possible to form the beam connecting portion 220 in only three directions, not the cross shape as shown in FIG. Thus, the connection unit according to the present embodiment can be modified into various forms according to the circumstances and needs.

9 to 11, a frame system according to an embodiment of the present invention will be described. FIG. 9 is an exploded perspective view showing a fastening structure of a frame system constructed by using a column member, a beam member, and a connecting portion according to an embodiment of the present invention, FIG. 10 is a cross- And FIG. 11 is a schematic plan view showing a fastened state of a framework system according to an embodiment.

As described above, the frame member 101 and the beam member 102 may be connected to each other by using the connection unit 200 to form a frame structure.

That is, the column members 101 are fastened to the upper end and the lower end of the column fastening part 210 of the connection part 200, respectively, and the fastening members 102 are respectively fastened to the 4 directional fastening part 220.

For example, the tightening member 300 is provided so as to surround the end portion 120 of the beam member and the beam fastening portion 220 while the end of the beam member 120 is received in the beam fastening portion 220. The fastening member 300 can be formed by using a pair of steel members having a "C" shape, and is fastened to the fastening member 300, the second fastening member 300 which penetrates the end portion 120 of the beam member and the beam fastening portion 220, And may further include a third fastening member 381 for fastening the fastening members 300 to further strengthen the fastening force.

Referring to FIG. 11, concrete or mortar is filled in the rectangular steel pipe reinforcing member of the column member to increase the compressive strength of the column member and to connect the upper and lower columns integrally to improve the rigidity of the joint as explained briefly above.

In this case, the filling material of the column member flows into the column coupling part 210 of the connection part by gravity, and the filling materials C1 introduced into the column coupling part 210 are inserted into the inside of the beam member 102 Lt; / RTI > In this case, when the filling material is not filled in the inside of the beam member 102, a partition or the like may be previously formed inside the beam member 102 so that the filling material can be introduced only to the end side of the beam member in advance. Also, when the filling material is to be introduced into the side of the beam member, it is preferable to use concrete or mortar having excellent fluidity as the filling material.
