強度を得ることが困難であった。2. Description of the Related Art When building a building, a steel frame such as an H-shaped steel is generally used as a horizontal beam connecting the adjacent steel columns, and the steel frame is surrounded by a reinforcing bar (main bar). A beam member is formed by fixing a quadrilateral staple around the periphery. However, in that case, it takes a lot of work on site,
High cost. In particular, when the concrete bearing wall is arranged on the lower side, the surplus strength of the beam member increases, which is uneconomical. As a countermeasure against this, there is known a method of arranging reinforcing bars at four corners of a prismatic jig, and winding a slightly thin reinforcing bar around the periphery and welding the spiral bars in order to make the beam body only from the reinforcing bars. However, the size of the device becomes large and jigs of various sizes are required. According to this method, a hollow beam body whose shape does not collapse can be obtained, but it is difficult to connect to a column (steel frame) and it is difficult to obtain sufficient connection strength.

もできる。According to the first aspect of the present invention, a lightweight and durable beam can be made almost entirely of reinforcing bars, and since it has the lattice 4 there is no risk of losing its shape, and it can be manufactured at a factory or transported.
It is also possible to store them in piles. Since there are connection fittings 2 at both ends of the beam body 1, the beam body 1 can be handled like a steel beam, and since it is not necessary to wind a main bar or a stirrup on site, on-site work is simplified. Become. Since the V-shaped piece 7 has the main bar receiving portion 11 curved in an arcuate section, the V-shaped piece 7
The position of the end portion of the main bar relative to is accurately determined, the beam body is finished with high dimensional accuracy, and a jig for positioning the V-shaped piece 7 is not required at the time of assembly, which facilitates production. Since the lattice 4 is in the envelope surface of the four main bars 3, the position and number of the staple wraps 5 on the main bars 3 can be freely selected, and the attachment of the staples 5 and the change of the beam strength are easy. become.
Further, since the reinforcing plate 12 is welded to the V-shaped piece 7, the rigidity of the connecting portion between the end portion of the main bar 3 and the connecting fitting 2 is significantly increased,
As a result, the beam 1 and the pillar 17 can be connected by the single connecting plate 10. In particular, the beam 1 has an advantage of avoiding excessive quality when the bearing wall is arranged on the lower side and making it easier to balance the strength of each part. The connection fitting 2 may be composed of two sheet metal members 43 as shown in FIG.

You can choose the position quite freely. That is, by moving the bracket 18 shown in FIG. 2 to one side of the center plate 19 and welding it, the beam 1 can be laterally displaced with respect to the column 17, and in that case, there is no fear of reduction in strength. The reinforcing bar 22 has holes 21 in the columns 17 and holes 13 in the reinforcing plate 12.
Since it is arranged above and below the beam body 1, the beam body 1 and the pillar 1
The connection of 7 is effectively reinforced.

The V-shaped pieces made of strips are vertically connected to each other, and the vertex edges are integrally connected by a vertical connecting plate having connecting bolt holes, and the open edges of the V-shaped pieces are connected. A vertical reinforcing plate is formed on the outside of the V-shape and on the side opposite to the opening direction to have a main bar receiving portion that is curved in an arc shape in cross section, and is orthogonal to the connecting plate inside each V-shaped piece and has a reinforcing bar insertion hole. Welding to form connecting fittings, holding a pair of connecting fittings' connecting plates in the same vertical plane and welding the ends of the main bars made of reinforcing bars to the main bar receiving sections facing each other. From the vertical plate-shaped bracket protruding laterally from the connecting plate is overlapped and tightened by bolts, reinforcing holes are inserted into the hole and reinforcing hole insertion hole of the pillar to reinforce the connection portion with the pillar, Reinforced beam body.

筋製梁体の製造方法。3. A V-shaped strip comprising a pair of jigs, each of which is rotatable on the same horizontal center line, and a bracket corresponding to a vertical plate-shaped bracket projecting from a column of a steel frame, which is opposed to the pair of jigs so as to be adjustable in space. The V-shaped pieces are connected to each other by a vertical connecting plate having a connecting bolt hole in such a manner that the pieces are opened vertically opposite to each other, and the open end of each V-shaped piece is located outside the V-shaped and opposite to the opening direction. Curved in an arc shape in cross section to form the main bar receiving portion,
Each of the V-shaped pieces is fixed to the bracket with a connecting metal fitting, which is welded with a vertical reinforcing plate that is orthogonal to the connecting plate and has a reinforcing wire insertion hole, and is fixed to the bracket with two main bars below each of the opposing connecting metal fittings. The receiving part supports both ends of the two main bars, and the middle part is supported by the lifting lift to hold the main bar horizontally and weld the connecting metal fittings and the ends of the main bars, and then lower the lifting lift once. Similarly, another two main bars are welded to the connection fitting by turning 180 degrees, and a pair of main bars are horizontally supported by a lifting lift, while a lattice is welded between the main bars. Manufacturing method.
