Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. However, the embodiments of the present invention can be modified into various other forms, and the scope of the present invention is not limited to the embodiments described below. Further, the embodiments of the present invention are provided to more fully explain the present invention to those skilled in the art. The shape and size of elements in the drawings may be exaggerated for clarity.

Hereinafter, a frame structure according to an embodiment of the present invention will be described in detail with reference to the drawings.

Referring to FIGS. 1 and 2B, a frame structure according to an embodiment of the present invention may include a structural member 100 and a junction node structure 200.

As shown in FIGS. 2A and 2B, the frame structure includes a structural member 100 formed in a longitudinal direction and constituting a basic frame, and a structural member 100 disposed at a connecting portion of the structural member 100, The structural member 100 includes a plurality of steel pipe frames 110 arranged in the longitudinal direction between the joint node structures 200 and spaced apart from each other in the height direction And a web member 130 connected between the steel pipe frame 110 spaced apart in the height direction and formed in a shape having a reduced cross section relative to the steel pipe frame 110.

2A, a web member 130 having a relatively small cross-sectional area as compared with the steel pipe frame 110 is disposed between the upper steel pipe frame 110 and the lower steel pipe frame 110 disposed with a height difference, Can be disposed.

This is because the region where the web member 130 is disposed has a bending moment according to the long span of the structural member 100 compared with a region where the upper steel pipe frame 110 is disposed and a region where the lower steel pipe frame 110 is disposed Because it works small.

2A and 3A show a configuration in which two steel tube frames 110 are disposed with a height difference and a web member 130 is provided between steel tube frames 110 to form the structural member 100 However, the present invention is not limited thereto, and three or more steel tube frames 110 may be disposed with a height difference, and a structural member 100 may be formed while a web member 130 is disposed between steel tube frames 110 Of course it is.

The reason why the plurality of steel tube frames 110 are disposed with a height difference and the web members 130 are disposed between the steel tube frames 110 as described above is that a single steel tube frame 110 is connected to the structural members 100 is formed, the structural member 100 may be elongated and it is difficult to exhibit a sufficient load supporting performance.

In addition, by forming the structural member 100 through the plurality of steel pipe frames 110 having a relatively small cross section, bonding work of the structural member 100 and the joint node structure 200 can be facilitated, thereby improving workability .

The structural member 100 and the joint node structure 200 can be manufactured separately in advance at a factory and transported to a construction site, and the frame structure can be installed sequentially through a craning facility.

In the drawings of the present invention, a pair of mounting flanges 111, into which the connecting flange 230 is inserted, are formed in the longitudinal direction at the end of the steel tube frame 110, The bolt member B is fastened in the transverse direction through the mounting flange 111 and the connecting flange 230 in a state where the connecting flange 230 formed with the connecting flange 230 is inserted.

However, the present invention is not limited thereto.

As shown in FIG. 1, at least two bolt holes 231 may be formed in the connection flange 230, and at least one bolt hole 231 may be formed in a longitudinal slot can do.

The joining node structure 200 having the connecting flange 230 and the mounting flange 111 can be formed by adjusting the position where the connecting flange 230 and the mounting flange 111 are fastened through the slot-shaped bolt hole 231, The installation angle of the structural member 100 having the installed steel pipe frame 110 can be adjusted.

Also, it is possible to absorb a construction error that may occur in the connection process of the joint node structure 200 and the structural member 100 by utilizing the slot-shaped bolt hole 231 formed in the connection flange 230.

On the contrary, at least two bolt holes may be formed in the mounting flange 111 to be fastened to the connection flange 230, and at least one of the bolt holes may be formed in the shape of a long lengthwise slot to be.

That is, at least one of the connecting flange 230 and the mounting flange 111 may be formed with two or more bolt holes, and at least one of the bolt holes may be formed as a slot having a long length in the longitudinal direction.

Although not shown, the connection flange 230 is installed at a downward slope at the junction node 210, so that the steel pipe frame 110 installed in the connection flange 230 is installed downwardly inclined relative to the junction node 210 .

The connection flange 230 may be provided to extend downward at an angle of 10 to 15 degrees at the junction node 210 so that the steel tube frame 110 is moved downward at an angle of 0 to 15 degrees at the junction node 210 It can be extended obliquely.

However, the present invention is not limited to the above-described angle, and a steel pipe frame 110 having various angles depending on the scale and curvature of the building may be used.

As shown in FIGS. 2A and 3A, the web member 130 may be a plate-shaped member that connects the steel pipe frames 110 disposed with a height difference therebetween.

The web member 130 may be a steel plate connected to a steel pipe frame 110 installed at a height difference and installed in the longitudinal direction of the steel pipe frame 110.

The mounting flange 111 is installed over a plurality of steel pipe frames 110 spaced apart in the height direction so that two or more connecting flanges 230 provided at the connecting node 210 are inserted into the insertion space portion 113 of the mounting flange 111 The bolt member B can be fastened integrally.

As shown in FIGS. 4B and 5B, the web member 130 may be formed by forming a web hole 131 formed in the plate member in the longitudinal direction or by forming a cutout 133 May be continuously and spaced apart.

The web member 130 may be lightened by continuously forming the web holes 131 in the web member 130 or forming the cutouts 133.

The area in which the web member 130 is disposed is smaller than the area in which the upper steel pipe frame 110 is disposed and the area in which the lower steel pipe frame 110 is disposed, So that the web member 130 can be stably supported against the load applied to the frame structure while reducing the weight.

[

When the dancing between the steel pipe frame 110 disposed on the upper side and the steel pipe frame 110 disposed on the lower side is large, the steel pipe frame 110 is installed staggered between the upper extending member 135 and the lower extending member 136, The weight of the structural member 100 can be reduced by reducing the amount of steel material through the truss member 137 forming the frame member 131, thereby improving the workability of the frame structure and improving the workability of the frame structure.

The web member 130 is installed over the entire length of the steel pipe frame 110 or over two thirds of the length of the steel pipe frame 100 and the web member 130 is formed by the web member 130 The dancing may be formed to be lower in the steel pipe frame 110 connected in the height direction than in the relatively high dance.

If the durability of the web member 130 becomes excessively larger than that of the steel pipe frame 110 while reducing the weight of the structural member 100 through the web member 130 whose section is relatively reduced as compared with the steel pipe frame 110, There is a problem in the structural performance of the semiconductor device 100.

7A, the diaphragm member 211-1 may be longer than the region where the body joint portion 213 is joined to the node body 211. However, as shown in FIG. 7B, It may be preferable to form a portion corresponding to a region where the main body joining portion 213 is joined to the main body 211 from the viewpoint of weight saving.

7A, the flange joint portion 215 includes a first flange 213-3 on the end side opposite to the direction in which the node body 211 is joined, a second flange 213-5 And a plate-shaped member joined to the horizontal joining plate 213-1.
