BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beam material used for constructing a building or the like.

[0002]

2. Description of the Related Art H-shaped steel is generally used as a beam material when constructing a building or the like. In this case, the beam is used with the web being vertical and the flanges being horizontal above and below it. A plurality of bolt insertion holes are formed in each of the web and the upper and lower flanges at both ends in the longitudinal direction of the beam member. Therefore, the beams are connected to each other (one beam is short and is often welded to columns, etc.) on both front and back sides of the web and the upper and lower flanges by connecting plates (both bolts). (Through through holes that match the insertion holes are made) are brought into contact with each other to form a sandwich, bolts are inserted from one side to these, and a nut is screwed to the bolt end protruding to the other side. It was something to do.

[0003]

In the state where the beam members are connected to each other, the connecting plate and the bolt head or the nut are projected on the upper surface of the upper flange. for that reason,
When installing floor materials for the upper floor on the top of this beam,
On this floor material side, it was necessary to process a recess for escaping the protruding portion or to attach a spacer to the upper surface portion of the upper flange other than the protruding portion. Therefore, it was extremely troublesome.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a beam member which allows a floor member or the like to be easily placed on top of beam members connected to each other. To aim.

[0005]

In order to achieve the above object, the present invention takes the following technical means. That is, the beam material of the present invention has a top surface flange at least at one longitudinal end.
A connecting brim portion having a plurality of bolt insertion holes, which horizontally protrudes laterally from a position lower than the upper surface flange by a predetermined dimension , is provided below the gage .

According to the present invention, the brim for connection has the upper surface flange.
Since it is installed at a position lower by a predetermined size than the
The beam members can be connected to each other in a state where the connecting plate, the bolt head, the nut, and the like do not project above the upper surface of the beam member. In this case, the top flange of the beam is
Since it is left as it is at the top, at the connecting part of the beam
Also, the floor material can be placed properly without interposing a spacer.
It

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of an essential part showing a state in which beam members 1 according to the present invention are connected to each other at their ends.
FIG. 6 is an enlarged sectional view taken along the line A. This beam 1 is made of H-shaped steel, and has a web 2 that is oriented vertically,
It has flanges 3 and 4 which horizontally project from its upper and lower parts toward both sides. The webs 2 on both ends in the longitudinal direction are provided with connecting flanges 5 that horizontally project from both sides of the upper flange 3 toward both sides of the web 2.

A plurality of (three in this embodiment) bolt insertion holes are bored in the connecting collar 5 along the longitudinal direction of the beam 1. In this embodiment, the connecting collar 5 is
It is formed by fixing a strip material having a predetermined length to the H-shaped steel web 2 by welding or the like. Then, the connecting flange portion 5 is reinforced by the strip plate member 6 provided by welding or the like so as to vertically connect the upper and lower flanges 3 and 4 along both side surfaces of the web 2. However, the invention is not limited to this, and the connecting collar portion 5 may be integrally provided over the entire length of the beam 1 by extrusion processing or the like.

At both ends of the beam 1 in the longitudinal direction, a plurality of (three in this embodiment) bolts are provided along the vertical direction at a portion between the connecting flange 5 and the lower flange 4 of the web 2. The insertion hole is formed and the lower flange 4 is formed.
A plurality of (three in the present embodiment) bolt insertion holes are bored along the longitudinal direction. These are substantially the same as conventional ones, and when different sizes of H-section steels are used as raw materials, the number of these bolt insertion holes may be increased or decreased.

In order to connect the beam members 1 having the above-described structure to each other, through holes corresponding to the respective bolt insertion holes are formed on both front and back surfaces of each of the connecting flange 5, the web 2, and the lower flange 4. The connecting plates 7, 8, 9, 10, 11, 12 that are held are brought into contact with each other to form a sandwich state, and these are connected with a bolt 13 and a nut 14. In the present invention, as the material of the beam member 1, in addition to the H-shaped steel, T-shaped steel, mountain (L) shaped steel, grooved steel and the like can be used. In addition, it is not limited to the case where the end portions are connected to each other, but one beam member 1 uses a side surface in the longitudinal direction thereof, and the other beam member 1 uses the end portion thereof to form a T-shape. It is also possible to connect to.

[0011]

According to the invention present invention, the connecting flange portion upper surface Hula
Since the positioned lower by a predetermined dimension than Nji, in the connected state the beam members mutually coupling plate and the bolt head or nut or the like does not protrude from the top surface flange to the upper. Therefore, when a floor material or the like is placed on the connecting portion of the beam material , it is not necessary to form a recess in the floor material or the like, or to interpose a spacer, and the work becomes easy.
