Description
技术领域 technical field
本实用新型属于维修桥梁的桥梁体外预应力加固技术，具体涉及一种桥梁体外预应力加固缆索转向块。The utility model belongs to the bridge external prestress reinforcement technology for maintaining bridges, in particular to a bridge external prestress reinforcement cable steering block.
背景技术 Background technique
体外预应力加固技术作为结构加固在桥梁的维修加工过程中已广泛使用。现有的加固中预应力缆索的转向是通过混凝土的转向块来实现的。混凝土的转向块预制麻烦，特别是转向孔实施比较麻烦，同时，现场使用锚固混凝土的转向块也比较麻烦。External prestressing reinforcement technology has been widely used as structural reinforcement in the repair and processing of bridges. The deflection of the prestressed cables in the existing reinforcement is achieved through concrete deflection blocks. The prefabrication of the concrete steering block is troublesome, especially the implementation of the steering hole is troublesome, and at the same time, the use of the steering block for anchoring concrete on site is also troublesome.
发明内容 Contents of the invention
本实用新型的目的在于提供一种桥梁体外预应力加固缆索转向块，以解决上述问题。The purpose of the utility model is to provide a bridge external prestressed reinforcement cable steering block to solve the above problems.
本实用新型的技术方案为：桥梁体外预应力加固缆索转向块，它包括支承板，支承板上开设锚固连接孔，间隔连接有支撑导向板，每个支撑导向板上开设转向孔，缆索转向管穿过每个撑导向板上的转向孔，各转向孔依次的圆心的连线为转向圆弧。The technical scheme of the utility model is: the external prestressed reinforcement cable steering block of the bridge, which includes a support plate, anchoring connection holes are set on the support plate, support guide plates are connected at intervals, each support guide plate is provided with a steering hole, and the cable steering tube Through the steering holes on each brace guide plate, the line connecting the successive circle centers of each steering hole is a turning arc.
相邻的两个支撑导向板之间不平行设置。Two adjacent supporting guide plates are not arranged in parallel.
上述结构的转向块利用钢板拼装制做，加工简单，施工锚固操作方便，解决了现有混凝土转向块的连接锚固困难等问题。The steering block of the above structure is manufactured by assembling steel plates, which is simple in processing, convenient in construction and anchoring operation, and solves the problems of difficult connection and anchoring of the existing concrete steering block.

具体实施方式 Detailed ways
如图2所示，支承板包括侧板1.1和与侧板连接顶板1.2，侧板1.1和顶板1.2上均开设有锚固连接孔，并分别通过锚筋1.3和1.4与箱梁2连接。As shown in Figure 2, the support plate includes side plates 1.1 and top plates 1.2 connected to the side plates. Both the side plates 1.1 and the top plate 1.2 are provided with anchor connection holes, and are connected to the
如图1所示，侧板1.1和顶板1.2间间隔焊接连接有5块支撑导向板3.1、3.2、3.3、3.4和3.5。每块支撑导向板上开设有转向孔，如图2中所示支撑导向板3.5上的转向孔4.1和4.2；每块支撑导向板上的转向孔数量根据所要导向转向的缆索而定，本实施例中的每块支撑导向板设有两个导向孔；缆索转向管5.1穿过上一排的支撑导向板的导向孔；缆索转向管5.2穿过下一排的支撑导向板的导向孔，每一排的各转向孔依次的圆心的连线为转向圆弧，以便于缆索转向管的穿过，为了便于实现各转向孔依次的圆心的连线为转向圆弧，相邻的两个支撑导向板之间不平行设置，即支撑导向板3.1、3.2、3.3、3.4和3.5的布置方式是：每个支撑导向板应该沿同心圆的半径布置，这样各支撑导向板上同排的导向孔圆心连线易于实现在同一圆弧线上。As shown in Fig. 1, five support guide plates 3.1, 3.2, 3.3, 3.4 and 3.5 are welded at intervals between the side plate 1.1 and the top plate 1.2. Each support guide plate is provided with turning holes, as shown in Figure 2, the turning holes 4.1 and 4.2 on the support guide plate 3.5; Each support guide plate in the example is provided with two guide holes; Cable diversion tube 5.1 passes the guide hole of the support guide plate of last row; Cable diversion tube 5.2 passes the guide hole of the support guide plate of next row, each The line connecting the successive circle centers of each steering hole in a row is a turning arc, so as to facilitate the passage of the cable steering pipe. The plates are not arranged in parallel, that is, the arrangement of the support guide plates 3.1, 3.2, 3.3, 3.4 and 3.5 is: each support guide plate should be arranged along the radius of the concentric circle, so that the centers of the guide holes in the same row on each support guide plate The connecting lines are easy to realize on the same circular arc.
