する場合には具合が悪い。2. Description of the Related Art Heretofore, in order to construct a building in a narrow place, a ramen structure has been adopted for its frame. In this ramen structure, as shown in FIG. 5, a pillar a is required, so that the effective dimension of the frontage W is reduced by about 80 cm to 120 cm. Particularly, when building a narrow frontage building in which both sides are sandwiched by adjacent land. Is sick.

ってしまう。In the rigid frame structure, the beam D of the girder b to be erected on the column a requires about 1/8 to 1/12 of the span, so if the span is 10 m, it becomes about 80 cm to 100 cm. Unless a beam is projected on the ceiling surface c as shown in FIG. 6, the floor height H is inevitably increased. When the floor height H increases, not only does the rise of the stairs become large and the usability deteriorates, but also the amount of exterior and interior materials used increases and the cost increases.

Assuming m, the span 1 can be up to about 1400 cm. At this time, the beam structure D of the void beam 2 is about 32 cm, which is a much smaller value than the conventional beam structure.

応力になっても強度的には十分である。Here, as shown in FIG. 4, the beam diameter D of the void beam 2 is 32.6 cm, the diameter φ of the void hole 2a is 20 cm, and the truss bar 3 is D16 (a = 1.99 cm 2 / piece, using SD30). Left and right two,
The main reinforcement is D16 with four upper and lower lines. If the cover thickness h is 4.5 cm, the effective thickness d = Dh = 32.6-4.5 = 28.1 cm. Distance between stress centers j = 7/8 d = 7/8 x 28.1 = a 24.5cm, concrete allowable tensile stress of f t = 2.0 t / from cm is 2, bending moment RM = a t · f t · j = 4 × 1.99 × 2.0 × 24.5 × 10 -2 = 3.9 tm Void Slab Assuming that the number of truss units in the beam is 2.5 sets (considering the half slab part), one set of RM
= 3.9 tm , the bending moment of the void beam M 0 = 3.9 tm × 2.5. On the other hand, the intermediate value of the bending moment M of the beam is 1 /
Taking 18 wl 2 and finding the maximum possible span l of the beam as M 0 = M, 3.9 tm × 2.5 = 1/18 × 0.35 × l 2 × 2.5 ≒ l ≒ 14 m, and can withstand a bending moment up to 14 m Will be. However, the truss muscle height h '23.6 cm, the length of one unit (width) U and 45cm, weight w = (0.45 × 0.326 -0.2 2 × π / 4) × 2400 + 30 × 0.45 + 300 × 0.45 = 350 kg / m 2 = 0.35 t / m 2 The shear stress τ of concrete is calculated from the shear force (wl / 2) / cross-sectional area (S) as follows: shear stress τ = (350 × 2.5 × 14/2) / (0.45− 0.20) × 0.28 × 7/8 ≒ 100,000 kg / m 2 = 10 kg / cm 2 , which is the allowable shear stress of concrete (Fc /
30) = 360/30 = less than 12 kg / cm 2, which guarantees safety, and furthermore, reinforcements can be arranged at the ends, so that even if the stress becomes about 1.5 times, the strength is sufficient.

なる。If a frame having a rigid frame structure is constituted by the wall columns 1 and the void beams 2 in this manner, both the columns and the beams can be formed to be thin, so that the width of the frontage can be kept as large as possible and the floor height can be maintained. Can be reduced as much as possible.

Although the stirrups with the 135-degree hooks are tied one by one, the use of truss bars as described above can greatly reduce the labor for arranging the bars. In other words, because it is a truss bar of a factory-produced product, bar arranging work on site is extremely simple,
Since the main reinforcement and the shear reinforcement are integrated, a load can be applied at the time of temporary construction, and a construction method that does not require a support such as a support is possible.

A wall pillar is used as a pillar, and a void beam is erected as a large beam on the wall pillar to form a rigid frame structure, and a half PC board is attached between the void beams to form a floor, so that the frontage is widely held. In addition, it is possible to design a building with a low floor without protruding beams on the ceiling surface, the rise of the stairs is reduced, the usability is improved, and the building materials such as exterior and interior are reduced, so the cost can be reduced. And so on.
