First, the column to which the present invention is applied is a factory-manufactured column body, which is manufactured in advance at a factory so as to be assembled only at the construction site, and then transported and installed. This type of column is usually called Precast Concrete (PC). Centrifugal casting column bodies can also be defined as precast casting columns in a broad sense as factory manufactured columns. Therefore, in the detailed description of the present invention, precast casting and centrifugal casting columns are not distinguished, Will be described. The present invention has a basic feature in the structure of connecting columns, and has a different feature in the method of installing a steel beam using this structure.
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. First, a basic embodiment of the present invention will be described mainly with reference to Figs. 1 to 4, and another embodiment of the present invention will be described with reference to Figs. 5 to 7, where necessary. In each of the drawings, reference numeral W designates a welding portion (of course, only the portion indicated by W is not on the welding portion).
The present invention provides a structure in which two columns having a unit length, that is, the first and second columns 10 and 20 are connected in a longitudinal direction continuously. It goes without saying that the third to fourth columns may be further connected using the same method. The length of the first and second columns 10 and 20 may correspond to the height of the floor, and may be, for example, 2 to 3 m, and the length of the column may be further increased or decreased according to the designer's selection.
The first and second columns 10 and 20 may be circular columns or polygonal columns such as square, hexagonal or octagonal. When the first and second columns 10 and 20 are centrifugal columns, the interior of the first and second columns 10 and 20 is generally hollow, but is not limited thereto. The first and second columns 10 and 20 may be steel reinforced concrete (SRC) columns or steel reinforced concrete (RC) columns in which only reinforcing bars are installed. In the present specification, for convenience of explanation, the RC column is illustrated and described as an example, but should not be construed as being limited thereto.
The connecting body 30 is inserted into the connecting portion of the first and second columns 10 and 20. [ The connecting member 30 is manufactured through a separate process from the molding of the column, and it is preferable that the connecting member 30 is formed in a shape corresponding to the shape of the first and second columns 10 and 20. Each of the figures is an octagonal column, so that the plane shape of the connecting body 30 is also in the same octagonal shape as the column. The height H of the connecting member 30 is preferably equal to the height of the steel beams 40 and 40 to be installed.
The connector 30 includes an upper flange 31, a lower flange 32 and a central cylinder 33 for allowing them to be secured up and down in a parallel state. As shown in FIG. 6, the upper and lower flanges 31 and 32 have the same shape as the cross section of the first and second columns 10 and 20, and the central cylinder 33 can have a polygonal shape, but the cylindrical shape is smooth. Fig. 6 (a) shows a connecting body 30 used for a rectangular column, and Fig. 6 (b) shows a connecting body 30 used for a circular column. The basic structure of the connector 30 in any form is the same. In the present specification, the upper and lower flanges 31 and 32 are described as having a donut shape by having a circular hole 35 in the center thereof.
The upper and lower flanges 31 and 32 and the central cylinder 33 are welded together. The outer diameter D1 of the central cylinder is smaller than the length D2 of the opposite sides of the upper and lower flanges 31 and 32 and the diameter thereof when the upper and lower flanges 31 and 32 are circular. Thus, it is preferred that the connector 30 has a shape similar to a bobbin, but it does not preclude the use of other shapes within the scope of achieving the same purpose and function.
According to the embodiment of the present invention, the upper surface is in contact with the upper flange 31, the rib plate 34, whose one side is in contact with the central cylinder 33 and whose lower surface is in contact with the lower flange 32, (Not shown). The rib plate 34 is a rectangular plate, which is provided to increase the rigidity with respect to the load in the vertical direction when the column is erected, and is also used for easily joining the steel bars 40, 40 described later. The rib plate 34 is installed in a radial form about the central cylinder 33 on the plan view and fixed by welding. 3, eight rib plates 34 are provided, but the number of the rib plates 34 can be adjusted as needed.
The first joining means is such that the first column (10) and the upper flange (31) are joined while being in contact with each other. The second joining means is provided so that the second column 20 and the lower flange 32 are joined together in a state in which they are butted together. Various methods can be used for the first and second joining means. The first and second bonding means may be the same or different. Therefore, only the first joining means will be denoted by the same reference numerals in the following description.
According to the first embodiment, the first joining means can include a finishing plate 50 that is formed integrally with the first column 10 at the end of the first column 10. The finishing plate 50 is welded to the upper flange 31 of the connector 30 in a surface contact state. The finishing plate 50 has the same cross-sectional shape as the first column 10 and can be welded to the upper flange 31 along the perimeter in a collapsed state. The finishing plate 50 may be welded or bolted to a plurality of the rod members 11 provided in the first column 10.
Here, the bar material 11 is used as a tensile material and may be a reinforcing bar or a linear steel material having a thread at an end thereof. The bar material 11 protrudes through the first through hole 51 provided in the finishing plate 50 and the bolt 52 is fastened to the end thereof. The upper flange 31 is also provided with a second through hole 31a through which the bolt 52 is inserted. Whereby the finish plate 50 and the upper flange 31 can be in surface contact with each other.
According to another embodiment of the present invention, as shown in Fig. 5 (a), the bar material 11 may be fastened by the bolts 52 after passing through the first and second through holes 51 and 31a have. 5 (b), the end portion of the bar stock 11 may be fixed by welding while passing through the second through hole 31a of the upper flange 31 without the finishing plate 50 . In this manner, the upper flange 31 and the first column 10 can be connected to each other. As shown in Fig. 5 (b), the finishing plate 50 may be optional in the present invention.
The steel frame and column simultaneous joining structure for a centrifugal casting column according to the present invention having the above-described structure can be manufactured by joining the first and second columns (30, 32) to the connecting body (30) by using the upper and lower flanges 10 and 20 at right angles to each other. The steel rods 40 and 40 are typically H-shaped steels wherein each flange 41 of the steel section is welded to the upper and lower flanges 31 and 32 and the web 42 is welded to the rib plate 34. If the width of the rib plate 34 is wide, the steel bars 40 and 40 may be connected by bolting or riveting. Although not shown in the drawing, it is possible to install a steel beam more conveniently with a bolt by providing a rib plate having a wide width in advance.
7 shows that the steel bars 40 and 40 are installed in the first and second columns 10 and 20 in various ways. The steel beam 40 shown on the left side is joined to the connecting body 30 by bolting while a reinforcing plate is attached thereto and the steel beam 40 shown on the right side is joined to the connecting body 30 by welding. Different environments will determine which method to use.
The present invention having the above-described constitutions and effects can be modified in various ways, and the above description is not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope thereof.
