【発明の詳細な説明】
（発明が属する技術分野）
本発明はPC（プレキヤストコンクリート）の大
梁と小梁の接合方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Technical field to which the invention pertains) The present invention relates to a method for joining large beams and small beams of PC (precast concrete).
（従来技術の問題点）
従来知られているPC大梁とPC小梁の接合方式
は、一体的接合が期待できるものは施工性におい
て問題があり、施工性が良好なものは構造上、一
体性に欠け、一長一短である。(Problems with the conventional technology) Conventionally known joining methods for PC girders and PC beams have problems in workability when an integral joint can be expected; There are advantages and disadvantages.
（発明の目的と特徴点）
本発明はPC大梁とPC小梁を能率良く一体的に
接合することができる新規方法を提供することを
目的としており、その構成上の特徴は、PC小梁

前記凹陥部にモルタルを充填する点にある。(Objective and Features of the Invention) The present invention aims to provide a new method that can efficiently and integrally join a PC girder and a PC small beam. PC the protrusion of the temporary steel material attached to the top of the end.
After placing it on the hardware embedded in the upper corner of the girder and welding, attach the plate embedded in the recessed part on both sides of the PC girder and the plate embedded in the side of the PC girder. The method consists of welding through the joints, and then filling the joints and the recessed portions with mortar.
（実施例）
以下、図示の一実施態様に基いて本発明を具体
的に説明する。(Example) Hereinafter, the present invention will be specifically described based on an embodiment shown in the drawings.
図において、１がPC大梁、２がPC小梁であ
る。 In the figure, 1 is the PC girder and 2 is the PC small beam.
PC大梁１には、予め、接合箇所の上面の隅部
にアングル状の金物３が、同じく側面にプレート
４が、それぞれ埋込まれており、また、PC小梁
２には、予め、端部上面に仮設用鋼材５が添設さ
れ、両側面の凹陥部６，６′にプレート７，７′が
埋込まれている。 In the PC girder 1, angle-shaped hardware 3 is embedded in the corner of the upper surface of the joint, and a plate 4 is embedded in the side surface. Temporary steel material 5 is attached to the top surface, and plates 7, 7' are embedded in recesses 6, 6' on both sides.
仮設用鋼材５はPC小梁２の端面から若干長突
出しており、本発明では、まず、この突出部を既
に架設されているPC大梁１の金物３の上に載置
し溶接により固定する。 The temporary steel material 5 projects slightly from the end face of the PC beam 2, and in the present invention, first, this projecting portion is placed on the hardware 3 of the PC beam 1 that has already been erected and fixed by welding.
このようにしてPC小梁２を安定した状態で仮
設した後、プレート７，７′とプレート４とを添
えプレート８，８′を介して溶接する。 After the PC beam 2 is temporarily installed in a stable state in this way, the plates 7, 7' and the plate 4 are welded together via the supporting plates 8, 8'.
以上の溶接作業の終了後に、目地９と凹陥部
６，６′にモルタルを充填するが、凹陥部６，
６′を添えプレート８，８′の厚さより若干深く形
成することにより、側面の接合部をモルタルで完
全に被覆することができる。 After the above welding work is completed, the joint 9 and the recesses 6 and 6' are filled with mortar.
By forming 6' slightly deeper than the thickness of the supporting plates 8, 8', the side joints can be completely covered with mortar.
なお、モルタルの品質は、無収縮モルタルで強
度は母材と同程度であることが望ましい。 As for the quality of the mortar, it is desirable that it be a non-shrinking mortar and have a strength comparable to that of the base material.
仮設用鋼材５は前述の接合作業が終つてから施
工されるスラブ１０内に隠蔽されるが、スラブ１
０はPC造とRC造の何れであつても構わない。 The temporary steel material 5 is hidden within the slab 10 that is constructed after the above-mentioned joining work is completed, but the temporary steel material 5 is
0 may be of either PC construction or RC construction.
（効果）
本発明は以上のようなものであるから、溶接作
業とモルタル充填作業とにより、安全に、かつ能
率良くPC大梁とPC小梁を一体的に接合すること
ができ、仕上がりも良好であるという効果が期待
できる。(Effects) Since the present invention is as described above, it is possible to safely and efficiently join the PC large beam and the PC small beam together by welding work and mortar filling work, and the finish is also good. It can be expected that there will be some effect.
