摘要：【中文】本发明公开了一种钢‑混凝土组合塔与混凝土箱梁固结施工方法，组合塔与箱梁的固结范围下延至箱梁底板以下2‑4m组合塔内部范围，上延至箱梁顶板以上设定高度处的组合塔内部范围，固结施工方法采用以下步骤：一)将索塔外包传力钢塔壁布置到位，在索塔外包传力钢塔壁内部设置多根均布的预应力钢棒；绑扎箱梁的0号块钢筋，并将0号块的顶板钢筋焊接在索塔外包传力钢塔壁上的箱梁顶板纵筋锚固钢板上；二)支设模板，浇筑索塔外包传力钢塔壁外侧的0号块混凝土；三)拆除模板，向索塔外包传力钢塔壁内浇筑微膨胀混凝土；四)待微膨胀混凝土达到设计强度后，张拉预应力钢棒并将其上端锚固。本发明能够保证固结点受力安全，并且施工方便。 【EN】The invention discloses a steel-concrete combined tower and concrete box girder consolidation construction method, wherein the consolidation range of the combined tower and the box girder extends to the range inside the combined tower 2-4m below a bottom plate of the box girder and extends to the range inside the combined tower at a set height above a top plate of the box girder, and the consolidation construction method comprises the following steps: firstly), arranging the force transmission steel tower wall outside the cable tower in place, and arranging a plurality of uniformly distributed prestressed steel bars inside the force transmission steel tower wall outside the cable tower; binding No. 0 steel bars of the box girder, and welding the top plate steel bars of the No. 0 block on a box girder top plate longitudinal bar anchoring steel plate on the wall of the force transmission steel tower outside the cable tower; secondly), erecting a template, and pouring No. 0 concrete block outside the wall of the force transmission steel tower outside the cable tower; thirdly), removing the template, and pouring micro-expansion concrete into the wall of the force transmission steel tower wrapped outside the cable tower; fourthly) after the micro-expansion concrete reaches the design strength, tensioning the prestressed steel bar and anchoring the upper end of the prestressed steel bar. The invention can ensure the stress safety of the consolidation point and is convenient for construction.

摘要：【中文】本发明提供了一种楔形的预应力筋用低回缩锚固装置及使用方法,该预应力筋用低回缩锚固装置包括低回缩锚板、夹片、楔形垫板、锚垫板、螺旋筋，所述低回缩锚板与锚垫板之间安装有所述楔形垫板。本发明的有益效果是:本发明尤其是解决了扁形锚具无法实现低回缩张拉的问题。且本发明结构简单、合理，可满足各种强度要求，不仅可以达到桥梁设计的高强度要求，并且通过低回缩锚板与锚垫板之间安装的楔形垫板的斜面配合使用，在二次张拉时，通过推动楔形垫板(补偿间隙)，从而使锚具回缩量有效控制在1mm以内；一次推进到位，操作简单、方便。 【EN】The invention provides a low-retraction anchoring device for a wedge-shaped prestressed tendon and a using method thereof. The invention has the beneficial effect that the problem that the flat anchorage device cannot realize low-retraction tensioning is particularly solved. The invention has simple and reasonable structure, can meet various strength requirements, not only can meet the high strength requirement of bridge design, but also can be used by matching the inclined planes of the wedge-shaped backing plates arranged between the low-retraction anchor plate and the anchor backing plate, and can effectively control the retraction amount of the anchorage device within 1mm by pushing the wedge-shaped backing plates (compensating gaps) during secondary tensioning; one-time pushing in place, simple and convenient operation.
