J Bolts-J鉤-3839048 J型螺栓

Bolts 產品介紹 / Product Description

中文描述：
J型螺栓（J型螺絲） 是一種末端彎成「J字形」的螺紋緊固件，主要應用於混凝土預埋固定，或作為吊掛、支撐件使用。其「J」形設計可在澆置混凝土時提供鉤掛抓力，防止脫落或旋轉，常見於鋼構底座、欄杆基座、柱腳、天花板懸吊等場合。

產品特點：

• 一端為彎鉤（J型），另一端具螺紋

• 常用於混凝土澆置前埋設，提供永久性固定點

• 適用於建築結構、鋼構基礎、道路護欄、機械底座等

• 材質：碳鋼、不鏽鋼（304 / 316）

• 表面處理：電鍍鋅、熱浸鍍鋅、防鏽塗層、不鏽鋼本色

• 尺寸：M6–M20，長度與彎鉤尺寸可依需求訂製

• 可搭配螺帽、墊圈使用，提升穩固性與受力分布

English Description:
J Bolts are threaded fasteners with one end bent into a “J” shape, commonly used for anchoring into concrete. The curved end provides a secure hold when embedded in poured concrete, preventing pull-out and rotation. They are widely used in structural steel base plates, fencing, support posts, and suspended ceiling systems.

Product Features:

• Bent “J” end provides anchor grip; threaded end allows for secure fastening

• Ideal for cast-in-place concrete anchoring

• Applications: structural foundations, machinery baseplates, pole mounts, railings

• Materials: Carbon steel, Stainless steel 304 / 316

• Finishes: Zinc-plated, hot-dip galvanized, anti-rust coatings, polished stainless

• Sizes: M6 to M20 and custom lengths and bends available

• Compatible with nuts and washers for increased strength and load distribution

🛠️ 使用教學 / Installation Instructions

中文使用說明：

1. 設計與選型
   根據結構需求與受力條件，選擇適當尺寸的J型螺栓（考慮直徑、彎鉤長度與伸入混凝土深度）。

2. 定位與固定模具
   在模板或鋼筋結構上預先固定J型螺栓，確保其位置與垂直度符合設計需求。

3. 澆置混凝土
   將螺栓連同鋼筋架一同澆注於混凝土中，讓彎鉤端完全包覆於混凝土內。

4. 固化與清潔螺紋
   待混凝土完全固化後，清理露出螺紋段，準備安裝其他構件。

5. 組裝與緊固
   安裝鋼構或底座等部件，並使用螺帽與墊圈鎖緊，完成固定。

English Instructions:

1. Select the Appropriate J Bolt
   Choose the correct size based on load and design requirements, including diameter, bend radius, and embed depth.

2. Position and Secure
   Fix the J bolt into place within the rebar cage or mold formwork to ensure accurate placement and vertical alignment.

3. Pour the Concrete
   Embed the bent portion of the J bolt completely in concrete during the pour.

4. Cure and Prepare Threads
   After concrete cures, clean any debris from the exposed threaded end.

5. Assemble and Fasten
   Mount structural components and tighten using nuts and washers to complete installation.
