Definitions

  • the present invention relates to a shear beam in a building. Background technique
  • the metal skeleton technology of reinforced concrete beams widely used at home and abroad is that the longitudinal bars are arranged parallel to the upper and lower sides of the beam; the upper and lower longitudinal bars are surrounded by a hoop to form a whole.
  • This kind of beam is mainly of poor rigidity, low resistance to shear stress and low ductility.
  • the steel bars are interspersed with concrete pouring connection, which makes the concrete at the node of the beam and column complicated and easy to be damaged during earthquakes. .
  • the present invention designs a shear beam based on the shortcomings of the metal skeleton in the reinforced concrete structure high-rise building. Disclosure of invention
  • the purpose of the present invention is to overcome the above-mentioned shortcomings of the existing metal skeleton shear beams, and provide a new type of shear beams that simplify the manufacturing process, can increase the steel strength and shear stress resistance by more than 2 times, and can reduce costs and save 10% of steel ,
  • the shear beam for buildings is composed of upper and lower longitudinal ribs, ribs, and connecting plates, and is characterized in that the ribs are cross-knotted on the upper and lower longitudinal ribs to form an "X" shaped frame structure. Welding is used at each crossing point to fix it. At the intersection of the upper and lower longitudinal bars and tension bars, it is fixed by welding with horizontal straight bars, and the hoops are spirally wound around the periphery of the upper and lower longitudinal bars.
  • a connecting plate is welded at both ends of the rib, and the connecting plate is provided with a hole for connecting the shear beam and the shear cylinder by a screw.
  • Figure] is a schematic structural diagram of the present invention.
  • the shear beam according to the present invention is composed of upper and lower longitudinal ribs, tension bars, and connecting plates.
  • the shear beams are mainly cross-knotted on the upper and lower longitudinal ribs (2) to form an "X" frame structure.
  • the shear beam is first made into pieces, and the upper and lower longitudinal bars are cross-knotted with a draw bar to form an "X" -shaped plane frame structure, which is used at each intersection. Welding is used to fix it; then, according to actual needs, each plane frame is welded with horizontal straight bars to form an integral shear beam, and then hoop is wound in a spiral manner around the periphery of the welded integral shear beam.
  • a connection plate with holes is welded at both ends, and the shear beam and the shear tube are connected and fixed by the screw through the connection plate to form a frame of the shear beam and the shear tube hole in the building, and then the concrete can be poured.
  • the manufacturing process of the shear beam is simple, and its rigidity and anti-shear stress performance can be increased by more than 2 times. At the same time, the cost can be reduced, and the steel can be saved by 10%.

Description

剪力梁
技术领域
本发明涉及 种建筑物中的剪力梁。 背景技术
目前国内外广泛采用的钢筋混凝土梁的金属骨架技术，皆为纵筋在梁的上下 平行排列； 通过箍筋将上下纵筋环抱成一体。 这种梁主要是钢度差， 抗剪切应力 性能及延性较低， 在梁与柱连接时钢筋相互穿插用混凝土浇灌连接， 使梁与柱的 节点处混凝土受力复杂， 地震时易被破坏。 本发明依据钢筋混凝土结构高层建筑 物中金属骨架的不足之处， 设计了一种剪力梁。 发明的公开
本发明的目的在于克服上述现行金属骨架剪力梁之不足， 提供一种制作工艺 简 其钢度、 抗剪切应力性能可提高 2倍以上， 同时又可降低成本， 节省钢材 10%的新型剪力梁，
本发明提供的用于建筑物的剪力梁， 它是由上下纵筋、 拉筋、 连接板组成， 其特征在于在上下纵筋上采用拉筋交叉扣结， 形成 " X " 形框架结构， 并在各 交叉点处采用焊接的方式加以固定； 在上下纵筋与拉筋的交点处， 采用横向直筋 焊接加以固定， 并在上下纵筋的外围以螺旋的方式缠绕箍筋； 在上下纵筋的两端 焊接有连接板， 连接板上开有采用螺杆连接剪力梁与剪力筒的孔。 附图的简要说明
图】 为本发明结构示意图。
其中： （I )一横向直筋 （2)—上下纵筋 （3)~连接板
(4)~拉筋 （5)~箍筋 （6)~孔 本发明所述的剪力梁， 是由上下纵筋、 拉筋、 连接板组成， 其主要是在上下 纵筋 (2)上采用拉筋 (4)交叉扣结， 形成 " X "形框架结构， 并在各交叉点处采用 焊接的方式加以固定； 在上下纵筋 (2)与拉筋 (4)的交点处采用横向直筋 (1)焊接加 以固定， 并在上下纵筋 (2)的外围以螺旋的方式缠绕箍筋 (5); 在上下纵筋 (2)的两 端焊接有连接板 (3), 连接板 （3)上开有孔 (6)， 通过孔 (6)采用螺杆的方式将剪力 梁与剪力筒连接固定。 实现本发明的最佳方式
本发明所述的剪力梁， 在制做中首先将剪力梁分片制做， 将上下纵筋用拉筋 交叉扣结， 形成 " X " 形平面框架结构， 并在各交叉点处采用焊接的方式加以 固定； 然后再根据实际需要， 将各平面框架用横向直筋焊接成整体的剪力梁， 再 用箍筋以螺旋的方式缠绕在焊接成整体剪力梁外围，剪力梁的两端焊接有带孔的 连接板，采用螺杆通过连接板将剪力梁与剪力筒连接固定形成建筑物中的剪力梁 与剪力筒孔的框架， 再用混凝土浇灌即可。 该剪力梁制作工艺简单， 其钢度、 抗 剪切应力性能可提高 2倍以上， 同时降低成本， 可节省钢材 10%
