Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a frame for a prefabricated building,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a frame for a building and a construction method thereof, and more particularly, to a frame for a building and a construction method thereof having a minimum size when the fastening members are not overlapped when the frames are connected .

Generally, the prefabricated building is a structure that prefabricated more than half of the buildings such as basic frame, electric wiring, bathroom and so on, and assembles the block like a block in the site where the building is installed. It is relatively shorter than the ordinary reinforced concrete building There is an advantage that it is easy to demolish and change the structure.

Therefore, prefabricated buildings have been widely used in developed countries such as Europe, Japan, and the United States. Recently, it has been applied to schools, defense business facilities in Korea. Especially, Or more.

The frame of the prefabricated building is made by connecting frames such as "H" beam, "C" shaped beam, and hollow square beam. At this time, connections between the frames are generally performed through welding. However, when the frames are connected through welding, it may cause damage or deformation of the frame welded portion, decrease of the connection strength between the frames, and difficulty in dismantling the frame.

In order to solve the above problems, techniques for making the skeleton of a prefabricated building through bolting have been developed. As a related art, Korean Utility Model Registration No. 20-0404746 discloses an angle structure in which a steel plate having four holes is welded to both ends of a cube having four female thread holes on each side, However, as shown in Fig. 3, there is a restriction that only a frame of a rectangular parallelepiped having at least one side omitted can be combined.

As another technique, the techniques shown in Figs. 1 and 2 are known. Fig. 1 is a frame for a prefabricated building according to the prior art, and Fig. 2 is a connection example of frames according to the prior art. 1B is a front view, a right side view, a left side view, and a rear view of the frame 10, and Fig. 1C is a sectional view of the frame 10 10). The frame 10 includes a main body 11 having a hollow rectangular parallelepiped shape, a work hole 12 formed on each of five surfaces constituting one end and the other end of the main body 11, (13). Here, the four fastening holes 13 are formed at symmetrical positions (that is, mirror symmetry) with respect to an imaginary straight line VL bisecting the area of each surface. The operator puts his / her hand into the work hole 12 to perform a connecting operation of the frames 10, a wiring operation via the hollow of the frame 10, and the like. Therefore, the work hole 12 should be sized so that the hand of the worker 12 can enter and perform a predetermined operation. The fastening members (the bolts 14 and the nuts 15) inserted into the fastening holes 13 and connecting the frames 10 are also made to be capable of tightly connecting and holding the frames 10 at a predetermined strength or more (I.e., length, cross-sectional area, etc.). At this time, the size of the fastening hole 13 corresponds to the cross-sectional size of the threaded end of the bolt 14. As a result, the frame 10 must have a size (i.e., a width W, a length D) satisfying the above-mentioned size condition. However, when the size of the frame 10 is increased, there arises a problem that the increase of the material cost, the increase of the transportation cost due to the weight increase, and the difficulty of the construction are also increased. In addition, when the size of the frame 10 is made smaller than necessary by satisfying only the required size of the work hole 12, there arises a problem that the bolts 14 are overlapped when the frames 10 are connected, (See Fig. 2).

Here, the fastening holes 130 are formed at positions asymmetrical with respect to an imaginary straight line VL that is parallel to the edge of the surface on which the fastening hole 130 is formed and is located in the surface and bisects the area of the surface. Here, the shape of the work hole 120 may have a shape such as a circle, an ellipse, or a polygon. In addition, the work hole 120 may be two or more per side, if necessary. In addition, the number of the fastening holes 130 is not limited as long as the number of the fastening holes 130 is two or more and is formed asymmetrically with respect to the imaginary straight line VL.

2, the work hole 120 is formed at only one end of the frame 100, and the number of the work holes 120 is one for each face, And the fastening holes 130 are formed at regular intervals along the periphery of the work hole 120 and the number of the fastening holes 130 is four.

3, the fastening holes 130 according to an embodiment of the present invention may be positioned asymmetrically with respect to the imaginary straight line VL (i.e., not mirror-symmetrical), unlike the prior art shown in FIG. 1 Respectively. Therefore, even when the sizes of the main body 110 and the work hole 120 according to the embodiment of the present invention are the same as the sizes of the main body 11 and the work hole 12 according to the prior art shown in FIG. 1, The bolts 140 do not overlap with each other when they are connected to each other (see FIG. 4).

More specifically, in the first step S10, the basic error range is set in a clockwise or counterclockwise direction based on the matching, but the matching is set to '0' and the twist degree in the clockwise direction is set to '+' And set the torsion degree to '-' in a counterclockwise echo. In the third step S30, the maximum tolerance range is set to be clockwise or counterclockwise on the basis of matching, but the matching is set to '0', the twist degree is set to '+' in the clockwise direction, Set the degree to '-'.

Thereafter, the construction is started, and in the fourth step S40, the actual error is measured each time the frame for a building-like building according to the present invention is completed. At this time, the actual error is preferably transmitted in real time to a terminal such as a smartphone of an operator or an administrator of the site.
