VLM13(15)B系列张拉锚具 VLM15(13) Model B Flat Stress-end Anchorage

VLM型张拉端扁形（B型）锚固体系是由VLM15B型，VLM13B型扁形锚具（锚具每套含：扁形工作锚板、工作夹片、扁形锚垫板）、扁形螺旋筋、扁形金属波纹管、预应力钢绞线或预应力钢丝束组成．
VLM15B型，VLM13B型扁形锚具主要应用于后张空心板梁中．扁形锚具在施工张拉时，与其配套的张拉设备有YDQ260型前卡式千斤顶和YDB扁锚整体张拉千斤顶．YDQ26O千斤顶在张拉时是单孔逐根张拉，YDB系列千斤顶可整体一次性张拉，YDB系列千斤顶在预制场中非常适用，张拉效率每束可提高3—5倍，张拉应力均匀．可配套YBZ1-70高压电动油泵使用，也可配套2YBZ2-80型高压电动油泵使用。
VLM Stress-end Flat(type B) Anchorage System consists of VLM15B,VLM13B flat anchor (Each set including flat working anchor head, working wedge, flat anchor bearing plate, flat spiral reinforcement),flat metal corrugated duct and prestressed strand (prestressed wide bundle).
VLM15B,VLM13B flat anchorage systerm are used in the post-tensioning hollow plate beam.
When flat anchorage systerm are used in construction for stressing,they are equipped with the supporting devices-YDQ260 Jack or flat YDB series jacks. YDQ260 jack is used for single-hole one by one stretching at a time.YDB series are much suitable in the site for prefabrication with a three-fold increase in stretching efficiency pre bundle, and the stretching force uniform. They can be equipped with both YBZ1-70 portable electric high-pressure oil pumps and 2YBZ2-80 electric high-pressure oil pumps.
