Abstract

PROBLEM TO BE SOLVED: To contrive to save labor and shorten time in executing a steel skeleton using a column corner deck supporting member. SOLUTION: This column corner deck supporting member is of a structure having joints 4...4 made by butt welding ends of H shape steels 1 to four side surfaces 3A...3A of a column material 3 which is made by butt welding in a cross legs 2A...2A of T shape steels 2, 2 to both sides 1A, 1A of the web lateral of the H shape steel 1. In this case, brackets 6 of L shape cross section is welded between adjoining column material laterals 3A, 3A and between the top surface of joints 4, 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a column corner deck receiving member.

[0002]

2. Description of the Related Art When a steel frame is assembled in a steel frame concrete building, a column corner deck receiving member as shown in FIG. 5 is used at an intersection of a floor and a column.

The column corner deck receiving member is formed by welding the legs 2A, 2A of the T-shaped steels 2, 2 in a cross shape to both sides 1A, 1A of the web of the H-shaped steel 1 and welding them to form a column material 3. The ends 4... 4 are formed by butt-welding the end faces of the H-section steel 1 to the side surfaces 3A...

[0004] At the construction site, it is necessary to connect the column members up and down and connect the beam members 5 to the connections 4... Had been

[0005] By the way, when performing the later flooring work with the above-mentioned steel frame structure, it is necessary to attach a dam plate having at least a casting depth between the side surfaces of the pillars so that the poured concrete does not flow into the gap 3B of the pillars 3. Conventionally, this weir plate was welded after completion of the steel frame.

[0006]

However, there is a problem that this weir plate is extremely dangerous because it is performed before the flooring and the work is performed at a high place.

Further, since there are four connections per pillar, the number of welding points in a large-floor high-rise building or the like having a large number of pillars is enormous, which has been a major obstacle to the efficiency of on-site construction.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems, and a T-shaped steel leg is cross-welded to both sides of a web of an H-shaped steel by welding the four sides of the steel to the four sides. A pillar corner deck receiving member formed by butt-welding an end face of a mold steel, wherein an L-shaped bracket is welded between adjacent column material side surfaces and between the upper surfaces of the connections. It is.

[0009]

Next, an embodiment of the present invention will be described. FIG. 1 is a perspective view showing an embodiment of the present invention, FIG. 2 is a plan view, and FIG. 3 is a perspective view of a bracket.

[0010] The column corner deck receiving member of the present invention comprises T-shaped steel 2 on both sides 1A, 1A of the web side of H-shaped steel 1.
In the column corner deck receiving member, the end faces of the H-section steel 1 are butt-welded to the four side surfaces 3A... 3A of the column member 3 in which the two legs 2A and 2A are butt-welded and welded. An L-shaped bracket 6 is welded between adjacent column side surfaces 3A, 3A and between the upper ends of the connections 4, 4.

In the above description, both the H-shaped steel 1 and the T-shaped steel 2 are used for the sake of convenience to explain the form of the steel material, and more specifically, as shown in FIG. Means a shape in which a side plate is provided so as to intersect with the end face of, and a connection is erected on the surface of the side plate.

In the above, since the bracket 6 is not a strength material, it may be formed of a thin metal plate as long as it can block the cast concrete. The ribs 6A are press-formed on the bracket 6 to improve the strength.

[0013]

Next, embodiments of the present invention will be described. As shown in FIG.
Is joined with bolts or rivets 7.

At this time, since the bracket 6 is welded between the side surfaces of the columns and the surface of the connection, the flooring work can be started immediately. And concrete does not flow down even if concrete is poured.

[0015]

As described above, according to the present invention, since the brackets are welded in advance between the adjacent column side surfaces of the column corner deck receiving member and between the joint surfaces, the conventional method is dangerous and the construction is troublesome. The bracket mounting work can be omitted completely, and the steel frame assembling work can be speeded up.
