【発明の詳細な説明】 「産業上の利用分野」 本発明は、鉄骨架構のE字形エレメントとその建方に
関するものである。
TECHNICAL FIELD The present invention relates to an E-shaped element of a steel frame and its construction.

「従来の技術と発明が解決しようとする課題」 ベアリングウォールに係る鉄骨架構の外周部は、3m程
度の小スパンに形成されることが多い。
“Problems to be Solved by Conventional Techniques and Inventions” The outer peripheral portion of the steel frame structure related to the bearing wall is often formed in a small span of about 3 m.

In recent years, it has been proposed to use the square-shaped elements a shown in FIG. 8 on the outer peripheral portion of this type of steel frame structure.
This square-shaped element is made by welding a plurality of steel beam members a2 with a length equivalent to 1/2 span to appropriate places on both sides of a steel column a1 with a length equivalent to several floors. It consists of

According to this, compared with the case where the steel columns and the steel sides are separate members, the joining of steel beams at the construction site can be halved, and because the span is small, it is possible to transport the factory-produced elements by truck. It is possible, the construction period can be shortened, and the cost can be reduced.

(特公昭49−19568号公報)。
In the olden days, a plurality of steel beam members with a length equivalent to 1/2 span were joined by projecting only on one side at appropriate places of a steel column with a length equivalent to several floors, and further reinforcement was added to these. There is also an element provided with a diagonal member for forming a difference (Japanese Patent Publication No. 19568/1974).

しかし、これらの場合、次のような問題点がある。 However, in these cases, there are the following problems.

(a)梁の中央で鉄骨梁部材相互を接合するので、建入
れ精度を高くできず、甚だしく梁中央で段差を生じる。
(A) Since the steel beam members are joined to each other at the center of the beam, the installation accuracy cannot be increased, and a step is extremely generated at the center of the beam.

(b)梁全体としては未だ3つの接合箇所があって、2

(B) There are still three joints in the beam as a whole,
Factory joining of parts is required, and even though it is a factory joining, it is troublesome to join and a lot of splices are still required for on-site joining.

(c)梁上に載置するPCa床版に梁の現場接合部を逃げ

(C) The PCa floor slab placed on the beam needs a blind hole to escape the on-site joint of the beam, and also requires a blind hole work later.

(d)梁の中央部に余分の足場を要する。(D) An extra scaffold is required at the center of the beam.

(e)以上の要因によるコスト高を免れ得ない。(E) High costs cannot be avoided due to the above factors.

(f)特に、後者の場合、工場生産に益々手数がかか

(F) In particular, in the latter case, it takes more and more troubles for factory production, and further on-site construction requires more troubles in order to horizontally connect a large number of elements on the side.

As another element, there is an element in which beam spans each having a length of one span are swingably connected to the left and right sides of a column steel frame (JP-A-60-62370).

しかし、この場合、次のような問題点がある。 However, in this case, there are the following problems.

(C) Since the pillar steel frames are built with the beam steel frames on both sides folded, there is a risk that the beam steel frames may unexpectedly fall down, and the stability of each beam steel frame is poor during lifting, making it difficult to balance them. .

(d)以上より、この場合も、結局、コスト高を免れ得

"Means for Solving the Problem" In order to achieve the above object, the E-shaped element of the steel frame structure of the present invention has a plurality of full-length steel frames of a corresponding floor on one side of a steel column having a length corresponding to several floors. The beams are attached to each other by joining them in an assembled state at one end.

Further, the erection of the steel frame structure of the present invention has an E-shaped element in which one side of a steel column having a length corresponding to several floors is joined with a plurality of full-length steel beams of the corresponding floor at one end. After manufacturing the required number of these E-shaped elements, the E-shaped elements are respectively installed and connected to construct the outer peripheral portion of the steel frame structure.
A PCa outer wall plate is attached to the character element beforehand.

"Effect" With the above configuration, the E-shaped elements installed at the construction site are assembled by being joined to each other, but these E-shaped elements are attached with steel beams over their entire length. It suffices to join the ends of the steel beams to the steel columns of the adjacent E-shaped elements, and it is sufficient to join each at one place. In addition, when the number of floors is high, it is the same as the conventional method to join the built up E-shaped element steel bridge columns to each other vertically.

[Advantages of the Invention] The E-shaped element of the present invention has the following advantages.

鉄骨梁は、全長であり、端部で鉄骨柱に接合するの
で、建入れ精度を高くでき、梁中央で段差を生じない。
Since the steel beam has the entire length and is joined to the steel column at the end, the installation accuracy can be improved and no step is formed at the center of the beam.

鉄骨梁は、工場で1箇所、建築現場で1箇所の都合
2箇所の接合でよく、接合の手数を大幅に低減でき、多
くのスプライスを要しない。
Steel beams can be joined at two locations, one at a factory and one at a construction site, which can significantly reduce the number of joining steps and do not require many splices.

しない。したがって、該部の後の駄目孔工事も必要な
い。
The PCa floor slab installed on the beam does not require a dead hole like in the past. Therefore, there is no need for a dead hole construction after the portion.

梁の中央部に接合等のための余分の足場を要しな
い。
No extra scaffolding for joining etc. is required in the center of the beam.

A plurality of full-length steel beams are joined to one side of the steel column in advance in an assembled state to form an E-shaped element. Therefore, it is sufficient to lift and assemble as it is. There is no need to fold or open the beam. Therefore, the construction and the construction adjustment are easy, and the labor of construction is small.

大幅に削減できる。
With respect to the E-shaped element, in the factory, each steel beam is to be joined only by preliminarily joining one end to one side surface of the steel column, and neither welding of the temporary joining bracket nor joining of the temporary bolts to each bracket is necessary. Further, the joining of the steel beams in the field is only required to join the other end to the steel column, and it is not necessary to join both ends. Therefore, the time and effort of joining can be reduced significantly.

Since each element is formed in an E shape by fixing each steel beam to one side of the steel column at one end, it is possible to lift the steel beam in a balanced and stable manner when installing it. There is no inconvenience to fold or open, and there is no risk of the folded steel beams falling down unexpectedly.

Further, according to the construction of the steel frame structure of the present invention, in addition to the above-mentioned effects by using the E-shaped element, since the PCa outer wall plate is attached to the E-shaped element in advance and installed, the assembly is easier and quicker. Therefore, it is possible to further shorten the construction period, reduce the cost, and improve the safety.
