上記の如き従来の形状の鋳造ダイヤフラムにおいては、
以下に述べる如き種々の問題点があり、改善が求められ
ていた。In the cast diaphragm of the conventional shape as described above,
There are various problems as described below, and improvements have been demanded.

ーズでない応力の流れである。(1) Since the steel plate portion 4 at the center of the diaphragm has a uniform thickness, there is a waste of stress due to the rigidity of the column member 5 not being evaluated, and the stress flow is smooth depending on the mounting position of the beam member. Not always. FIG. 3 is a cross-sectional view of the joint between the cast diaphragm and the beam, showing the flow of stress. In the figure, 1 is a cast diaphragm, 4 is its steel plate portion, 6 is a beam material, and w is a welded portion, and the arrow indicates a flow of stress that is large in bending and not smooth.

造、資材管理が繁雑であった。(2) As shown in Fig. 4 (cross-sectional view of column-diaphragm joint), when the conventional cast diaphragm is grooved, the groove is one step, so The thick column member protrudes from the side surface of the cast diaphragm as shown in Fig. 5x and cannot be mounted. Further, in the case of a pillar material having a plate thickness smaller than the plate thickness suitable for the one-step groove, if welding is performed in order to obtain sufficient penetration, melt-through easily occurs. This state is the fifth
Shown in the figure (cross-sectional view of a conventional diaphragm / column welded part).
In the figure, 1 is a cast diaphragm, 5 is a pillar material, w is a welded portion, and d is a burn-through portion. If welding is performed with the fear of burn-through, welding defects such as insufficient penetration are likely to occur. Therefore, a casting diaphragm corresponding to each plate thickness is required, the types of casting diaphragms increase, and manufacturing and material management are complicated.
(3)手で持つところがついていないため、工場、組立の
際の持ち運びに不便であった。(3) It was inconvenient to carry around at the factory or assembling because there is no place to hold it by hand.

In the cast diaphragm, a hole having a size that allows concrete injection is provided in the central portion of the steel plate portion, and the thickness of the steel plate portion is formed such that the central portion is thin and becomes thicker toward the periphery. Is a groove processed portion provided with a backing metal formed in multiple stages, and the beam member joint is formed in a plane. The details will be described below with reference to the accompanying drawings.

FIG. The plan view shown in the figure is for the case of using a prismatic column material, and the plane shape changes depending on the shape of the column material as in the conventional case. The cross-sectional shape is that of the central portion as described above. In the figure, 11 is a cast diaphragm, 12 is a column member joint part, 13 is a beam member joint part, and 14 is a steel plate part. The post-joint portion 12 is subjected to groove processing in multiple stages like g1 and g2. Further, as shown in the sectional view (b), the steel plate portion 14 is formed so that the thickness of the central portion is reduced and the thickness thereof is increased toward the periphery. Further, a hole 7 is formed in the center of the steel plate portion 14. In addition, s is a scallop.

い。The shape of the groove processing of the column material joint portion 12 is as shown in FIG. 7 (a), (b),
Various types such as (c) and (d) are conceivable and are not limited to one form. In this way, by performing the groove processing in multiple stages on the column member joint,
Each cast diaphragm will have a groove that can accommodate multiple plate thicknesses. FIG. 8 is a view (cross-sectional view) showing that the cast diaphragm of the present invention can be used without any trouble in response to changes in the thickness of the pillar material without causing an irregular state with the surface of the beam member joint. . In FIG. 8, 11 is a cast diaphragm of the present invention, and 5y and 5z are column members having different plate thicknesses. Further, since the groove shape of the cast diaphragm of the present invention is processed so as to have a groove having a backing metal for any plate thickness, when welding with a pillar material as shown in FIG. There is no risk of burn-through and sufficient melt-in can be obtained. FIG. 9 shows a state in which a pillar material is welded to the cast diaphragm of the present invention. In the figure, 11 is a cast diaphragm, 5 is a pillar material, and w is a welded portion, which is a back plate metal in this case. Since u is present, no burn-through is produced.

イヤフラムを製造する必要がなくなり、製造種類を減す
ことが出来る。そのために製造コストの低減、在庫管理

得られる。By using the cast diaphragm of the present invention which is groove-processed in multiple stages as described above, it is not necessary to manufacture the cast diaphragm for each plate thickness of the pillar material as in the prior art, and the manufacturing types can be reduced. Therefore, various benefits such as reduction of manufacturing cost, easy inventory management, and easy material management at the work place can be obtained.
本考案の鋳造ダイヤフラムの鋼板部１４は、前述の如く
中央部の厚さを薄くし、周辺に向って厚さを増すように

材の仕口部の高い剛性を力学的に有効に利用することが
できると共に、ダイヤフラムの総重量を軽くすることが
できる。The steel plate portion 14 of the cast diaphragm of the present invention is made such that the thickness of the central portion is thin and the thickness is increased toward the periphery as described above. The shape of the cross section is curved as shown in Fig. 10 (a) and the thickness increases from the center toward the periphery.
As shown in (b), the thickness increases linearly from the center toward the periphery, as shown in (c), there is a thin parallel part in the center, and the thickness increases linearly toward the periphery, and various other types. It can be considered, but it is the same in that the central part is thin and the thickness is increased toward the periphery. By increasing the thickness of the steel plate portion toward the periphery in this way, stress can be smoothly flowed to the peripheral portion, and the high rigidity of the joint portion of the pillar material can be effectively utilized mechanically, The total weight of the diaphragm can be reduced.

る。In addition, since the beam member joint portion that joins the beam members is formed in a plane, the distance between the two diaphragms assembled to face each other and the girder height (flange height) of the beam member joined to this diaphragm
Even if there is an error in the welding, both can be welded without any trouble.
さらに、この誤差のため梁材の接合位置がダイヤフラム

果をもたらす。Further, even if the joining position of the beam member is deviated from the center of the diaphragm due to this error, the stress of the beam is smoothly transmitted to the inside of the diaphragm in cooperation with the taper of the steel plate portion. In FIG. 11, 11 is a cast diaphragm, 14 is a steel plate portion, 6 is a beam material, w is a welded portion, and the arrow indicates a shape in which the beam material joint portion and the steel sheet portion can be error-absorbed so that the flow of stress is smooth. By doing so, not only the rationalization at the time of factory production but also a significant reduction effect on the on-site man-hour is brought about.

が増しているので、強度的に心配はない。The shape of the hole (7 in FIG. 6) formed in the center of the cast diaphragm of the present invention described above is not limited to the rectangular shape as shown in the drawing, but may be circular or the like. These holes can improve workability such as carrying around in a factory or at the time of assembly. Further, when used in a steel pipe concrete structure or the like, it becomes possible to easily perform concrete filling and the like. Since the thickness increases toward the periphery, there is no worry about strength.

事の条件によっては、その一二を省略することも可能で
ある。The above-mentioned elements such as the multi-step groove, the change in the plate thickness of the steel plate portion, and the hole at the center of the steel plate, which are the features of the cast diaphragm of the present invention, may be omitted depending on the working conditions.
