Imahashi HOME > Business Business content Our job is to assemble the reinforcing bars according to the structural drawing of the building. In the concrete of a building with a reinforced concrete structure, although it is not visible from the outside, a cage-shaped reinforcing bar that serves as a framework is embedded. Reinforced concrete structures are used in most of the buildings we live in and act on, from buildings to bridges, tunnels, highways and subways. Even though it is the work of a rebar worker, there are various processes before assembling the rebar at the actual building site. Enforcement plan Even if it is called construction work, the whole process is made up of the cooperation of people of various occupations. The prime contractor is a construction company (general contractor). There are many general contractor subcontractors, including jumping work, steel reinforcement work, formwork work, plumbing work, and electrical work, and the professionals in each work are proud and responsible for the work. The first step in reinforcement work for Imahashi is construction planning. This is the work of reading out the type, quantity, budget, etc. of the reinforcing bars required for construction while looking at the design drawings of the building. The read data is compiled into a plan, construction drawing, estimate, etc. and submitted to the general contractor. We will exchange a construction contract and take care of the steel material as the material from the general contractor. In order to plan a rebar construction plan, you must first be able to read the blueprints. Therefore, recently, the number of rebar workers who are trying the "building construction management technology certification test" is increasing. Reinforcing bar processing The steel materials entrusted to us by the general contractor are brought to our factory and processed by cutting, bending, and combining based on the construction drawings. 鋼材という重量物を扱う仕事ですから、働く人にもある程度の体力が求められますが、最近では専用の機械や重機を利用するので必ずしも力持ちである必要はありません。工場では体力よりも施工計画書に対する理解力や正確に加工する技術力の方が重要なのです。また、溶接技能や鉄筋にワイヤーを掛けて動かす玉 掛技能も必要になります。そこでイマハシでは、ヤル気のある人を各種技能講習などに積極的に派遣しています。 ○本社工場 ●工場総面積／約13,860mm（約4,200坪）●工場主要設備／ホイストクレーン13機、切断機11台、自動曲げ機10台、曲げ機8台、T-MAX2台、スパイラル曲げ機1台、スポット溶接機3台 ○新田道工場 ●工場総面積／約10,296mm（約3,120坪）●工場主要設備／ホイストクレーン6機、切断機3台、自動曲げ機4台、曲げ機3台 出庫・運搬 工場で切断や曲げ加工、スポット溶接された鉄筋は建設現場ごとにまとめられ、間違いがないように工区が明記された札をかけて出荷を待ちます。工場から工事現場までの輸送もイマハシの仕事の一環。そこで当社では、輸送専用のトラック（10トン車）4台を自社保有しています。建設現場は常に工期との戦いであるため遅れは許されません。しかし、鉄筋は当社にとって大切な商品であることから、安全・確実な輸送も重要な課題。輸送担当者は、スピードと安全性という矛盾したテーマをクリアしなければならないのです。そのため、イマハシでは大型特殊運転免許を持ったベテランドライバーを配しています。 鉄筋工事会社のドライバーは、トラックの運転免許だけを持っていればいいというわけではありません。建設現場での荷降ろしに必要な小型クレーンの取り扱いもできなければならないのです。イマハシでは、ほとんどのドライバーが玉掛技能講習修了証を常に携帯しています。 組み立て Reinforcing bars brought from the factory will be assembled according to the drawing at the responsibility of Imahashi. The assembled reinforcing bars will eventually be buried in concrete and become the skeleton that affects the safety of the building. That is why a solid and reliable job is required. Reinforcing bar construction is a structurally important task, so the person in charge must have the skills and knowledge to perform construction in accordance with the correct reinforcement standards. In particular, foremen who are leaders in the field are given heavy responsibility. As for the qualification, a national qualification of a rebar construction technician (first grade) is required. Furthermore, the foreman is required not only to have the skills and knowledge of rebar construction, but also to have leadership and safety management for the craftsmen of his subordinates, as well as the ability to coordinate processes with formwork construction personnel, sword construction personnel, general contractors, etc. As you can see, the foreman is a heavy duty job, but at Imahashi, anyone with the ability is promoted to the foreman regardless of age. Even young people give high salaries and bonuses. Imahashi Co., Ltd.
