Abstract

PURPOSE:To reduce the number of component parts by welding a horizontal jointing plate at the end section of the column main-body of an H-shape steel, and by jointing the jointing plate to the horizontal surface of a beam via the jointing plate. CONSTITUTION:At both the upper and lower ends of the column 21 of an H- shape steel, rectangular horizontal jointing plates 22 are projected from the flanges 23, 23 of the column 21, and the lower ends of the flanges 23 and a web 24 are previously welded. Then, the jointing plates 22 are jointed to the horizontal section of a beam 27 with bolts 29. As a result, the number of man- hours can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a joint structure between columns and columns in a steel frame building.

BACKGROUND ART FIGS. 6 and 7 respectively show a joint structure between a column and a casing in a conventional steel frame building.

In Figure 6, a bracket (2) made by cutting an H-shaped steel into short lengths is welded to the side surface of a column (1) made of a square pipe, and a beam (3) made of the same (H-shaped steel) is welded to the side of the column (1) made of a square pipe.
Butt the end of the bracket (2) against the tip of the bracket (2), and also connect the flanges (4) (4) and the web (
5) 8 minutes are joined with bolts (8) via three joining plates (7).

In Figure 7, a pair of upper and lower T-shaped brackets (see from the side) are attached to the side of the pillar (1), which is also made of a square pipe.
10) Attach (10) with the bracket (11), insert the end of the beam (3) made of H-shaped steel between the bracket (10) and (10), and connect the bracket (10) and the The flanges (4) (4) of (3) are joined by bolts (8).

In both of the conventional examples shown in FIGS. 6 and 7, as shown in FIG. 5, the pillar (1) vertically penetrates the casing (3) without being separated by the casing (3). It has a pillar-first structure.

Problems to be Solved by the Invention In the conventional joint structure described above, in the one shown in FIG. 6, in order to rigidly connect the bracket (2) and the beam (3), three joint plates (7) are required as described above. This has the disadvantage that the number of parts and bolts increases, which increases the number of man-hours required for joining.

Also, in the one in Figure 7, there are two brackets) (
10) (10) is required and the number of parts increases.

Furthermore, as mentioned above, all of these conventional structures have a column-prioritized structure, and have the disadvantage that they cannot be applied as they are to a column-prioritized structure in which a beam passes through a column. Of course, if FIGS. 6 and 7 are turned 90 degrees and a half, it is possible to give priority to rice, but even in this case, the disadvantage of increasing the number of parts cannot be solved.

Means for Solving the Problems In order to solve the above-mentioned drawbacks, in this invention, a horizontal joint plate is welded to the end of the column main body made of H-shaped steel, and the horizontal joint plate is connected to the horizontal surface of the rice cake through this joint plate. It is characterized by

Effects According to the configuration of the present invention described above, a horizontal joint plate is welded to the end of the column in advance, and this joint plate is simply connected to the horizontal part of the rice cake with bolts. There is no need to separately transport a joint plate or bracket to the site, reducing the number of parts and the number of man-hours required for joining at the site.

Embodiments In the embodiments, FIG. 1 shows the structure of the joint portion between the pillar and the rice cake of the present invention, and FIG. 2 shows the structure of the lower end portion of the pillar. The column (21) made of H-shaped steel has a rectangular horizontal joint plate (22) at both its upper and lower ends so that its elongated end protrudes from the 7 langes (23) (23) of the column (21). and is welded to the lower end of its flange (23) and web (24). (joint play) (2
2) has two bolt holes (25) (25) on both sides of each flange (23) (23) in the thickness direction.
, and four bolt holes (25) are formed for one seven flange (23), and four bolt holes (25) are formed for the other flange (23).

On the other hand, the flange (27) is the same as before.
(2B) are made of H-shaped steel arranged so that they are vertically parallel, and if this wire (27) is a floor beam for the second floor, for example, on the top surface of its upper flange (28), Place the joint plate (22) at the lower end of the second floor column (21) and connect it with the bolt hole (29) using the bolt hole (25). Also, on the bottom surface of the lower flange (28), 1
Abut the joint plate (22) at the top of the floor column (21) and connect with the pole (25) in the same way. In addition, 籱 (27
) between the flanges (2B) (28), there is a multi-column (21
) Corresponding to the 7 flange (23) (23) of (21), a stiffener plate (30) (30) is welded to connect the flange in the direction perpendicular to this flange (27), and these stiffeners The plates (30) (30) transfer the vertical load from the second floor column (21) to the column (27).
It also has the function of effectively transmitting information to the pillar (21) side of the floor. (32) has a mesh-like reinforcing bar inside (33)
It is a concrete floor plate with reinforcement, and this floor plate (
The plate (34) is installed protruding from the end of 32).
(34) is installed on the upper surface of the 7-lunge (28) on the upper side of the scallop (27) and fixed with a bolt (35).

FIG. 3 is a side view showing the joined state of the pillar (21) and the scallop (27).

Furthermore, as shown in Figure 4, the connection between the pillar (21) and the thread (27) is a thread-first structure in which the thread (27) penetrates the pillar (21) in the horizontal direction. Compared to the column-prioritized structure shown in Fig. 5, the horizontal position of the column (21) can be changed arbitrarily for each floor, and the horizontal The advantage is that the plan is more flexible.

Effects of the Invention As described above, according to the present invention, the joint plate welded to the end of the pillar is connected to the horizontal part of the rice cake with bolts, so that parts other than the pillar and the rice cake are bolted. This has the effect of reducing the number of parts and reducing the number of man-hours required for bolt tightening. Moreover, since it is easy to create a structure in which the beam penetrates the columns in the horizontal direction, the horizontal position of the columns can be arbitrarily changed for each floor, i.e., the columns of each floor can be Because it is not necessary for the two to always match, the effect is that the horizontal plan becomes more flexible.
