Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to columns for frame structures such as general houses, factories, warehouses, public buildings, etc., and particularly to columns suitable for use as columns for two-story frame structures. be.

The pillars installed mainly at the corners of two-story wooden frame structures play an extremely important role in terms of wind resistance and earthquake resistance.

The traditional construction method is to connect horizontal members and reinforcing members to these pillars using mortise and tenon joints. For example, Fig. 12 shows a situation in which the eave girder B, which is a horizontal member, a girder, a base E, and a reinforcement member F, which is a reinforcing member, are connected to a pillar A, and the two eave girders B are the tenons. The length of the top of pillar A through which the hole passes is a.

The short groove d at the end of the barrel insert is fitted into the mortise a2 in the middle of the post A, and connected by an inclined large insert (Fig. 13). (Fig. 15), the base E is connected by fitting the fan at the lower end of the post A through the mortise e into the slot a3 (Fig. Figure 12).

In addition, there is also a frame structure in which square steel pipes for general structures are used as columns and shaped steel is used in at least part of the horizontal members instead of the wooden frame structure.

The problem that the invention aims to solve As mentioned above, in wooden frame structures.

Even if long and expensive square timbers are used for pillars, the strength of these parts will be reduced due to the large number of cuts, and the machining of joints such as grooves requires precision and skill.

In addition, the wall thickness of square steel pipes, which are approximately the same size as wooden columns, is specified by JIS as 2.3M or 3.2wm, and because they are thin, there is a problem of fatigue due to corrosion over time, and furthermore, they are used to connect horizontal members, etc. For example, as disclosed in Japanese Utility Model Publication No. 53-2403, it is necessary to fit a reinforcing member into the square steel pipe and make this part thicker in order to strengthen the parts where the parts are connected and to ensure the stability of the connecting bolts. becomes complicated. Yet again. Since it is not possible to nail square steel pipes to the base of water tanks, etc. on the exterior walls of buildings, there are construction problems when using square steel pipes for the columns of wooden frame structures to improve wind resistance and earthquake resistance. be.

The present invention has the characteristics that both the shape q and the wood have, and it is possible to connect horizontal members without the need for joint processing, and it is also possible to easily fix a water tank etc. by nailing, thereby solving the above-mentioned problems. This provides a column suitable for a wooden frame structure without a structure.

Means for Solving the Problems In the present invention, the mounting bracket for fastening the M frame member is made of a shaped steel and wood loaded with one or two surfaces sprayed into the hollow part of the shaped steel. The structure is such that it is fixed at a predetermined position.

This is to eliminate the fear that the base E will break due to the stress when the F is compressed.

Furthermore, the anchor bolt 42 is for preventing the horizontal and vertical movement of the column 1.

In addition, it works in cooperation with the protrusion 38 to disperse stress acting on the corners of the foundation G.

Also. Pipe columns 4 on the first and second floors shown in Figure 1
In 7.48, a column 49 (Fig. 11) composed of a section steel 50 made of miso section steel and a wood 51 loaded with one surface 51A exposed in the hollow part is used, and the column 49 is shown in the figure. However, a mounting bracket similar to that of the above embodiment may be fixed. In addition, it goes without saying that the design of the mounting brackets 5.22.35 will be changed to a shape and fastening means suitable for the use of shaped steel or rectangular steel pipes as horizontal members. v−y k+X'1'J ”JE

It is also possible to adopt a structure in which all of the reinforcement plates are integrally provided on each of the mounting fittings 5, 22, and 35 and reinforced with each other.

Effects of the Invention According to the present invention, not only does the shaped steel have excellent mechanical strength and is not much different in weight compared to conventional cedar poles, but the mounting brackets of the horizontal members are fixed to the shaped steel. As a result, there are no cut points and the column has excellent strength, especially against full bending and bending, and since it does not require the processing of joints, it is possible to provide a column that can be constructed in a short period of time and at low cost. Moreover, the wood loaded into the hollow part of the shaped steel not only helps increase the strength, but also makes it possible to easily construct a wooden frame structure using the exposed surface.
