    • A girder connection structure of a bridge is provided to assemble girders in a narrow area and installing the girders to the bridge quickly by assembling second girders to a first girder pivotably. A girder connection structure of a bridge comprises a first girder(110), second girders(120), and a vertical reinforcement(300). The first girder is rotatably connected with one ends of a plurality of horizontal beams(200). The second girders are installed two sides of the first girder separately, and the other ends of the horizontal beams are rotatably connected with the second girders. The horizontal reinforcements are installed to the opposing sides of the first and second girders. The horizontal reinforcement is provided with a hinge bracket to connected with the horizontal beam.
    • 提供了一种桥梁的大梁连接结构,用于在狭窄的区域内组装桁架,并通过将第二桁架可枢转地组装到第一桁梁上将梁快速安装到桥梁上。 桥梁的梁连接结构包括第一梁(110),第二桁架(120)和垂直加强件(300)。 第一梁与多个水平梁(200)的一端可旋转地连接。 第二桁架分别安装在第一梁的两侧,水平梁的另一端与第二桁架可旋转地连接。 水平加强件安装到第一和第二桁架的相对侧。 水平加强件设置有与水平梁连接的铰链支架。

    • A method for manufacturing a continuous bridge with a prestressed negative moment girder is provided to prevent a floor plate from being cracked by appling compressive stress to the floor plate. A method for manufacturing a continuous bridge with a prestressed negative moment girder(10) comprises steps of overturning the girder, supporting the two rear ends of the girder, and pouring a floor plate concrete(14) on an upper flange(11); pouring an abdomen concrete(16) and a lower case concrete(15) and prestressing the floor plate concrete; mounting the girder and a positive moment girder poured by the lower casing concrete only; bonding a connecting steel plate with a connected part between the negative and positive moment girders; and hardening the abdomen concrete and the floor plate concrete on the positive moment girder.
    • 提供了一种制造具有预应力负矩形梁的连续桥梁的方法,以防止通过将压应力施加在地板板上而使地板板破裂。 一种用于制造具有预应力负矩形梁(10)的连续桥的方法,包括:翻转所述梁,支撑所述梁的两个后端,以及将地板混凝土(14)浇注在上凸缘(11)上的步骤; 倾倒一个腹部混凝土(16)和一个下层混凝土(15)并对地板混凝土进行预应力; 安装大梁和仅由下套管混凝土浇筑的正矩梁; 将连接钢板与负向和正向力矩梁之间的连接部分接合; 并在正时力矩大梁上硬化腹部混凝土和地板混凝土。

    • A construction method of a girder bridge with a later-tension precast floor slab is provided to manage the girder bridge effectively by introducing compression stress to the precast floor slab and controlling the tensile crack generation. A concrete(C) is poured on an abdomen of a negative moment part girder. A positive moment part girder and the negative moment part girder are continuously placed on a pier(500). A precast floor slab(300) laid with sheath pipes is mounted on the negative moment part girder. Non-attached steel wires(330) are inserted in the sheath pipe and then tensed to apply compression force to the precast floor slab. The concrete is poured and hardened between the upper and abdomen parts of the positive moment part girder and on the connected parts between the positive and negative moment part girders.
    • 提供了一种具有较高张力的预制地板的梁桥施工方法,通过向预制地板施加压缩应力并有效控制拉伸裂缝的产生,有效地对梁桥进行了管理。 将混凝土(C)倒在负矩部分梁的腹部上。 正时矩部分梁和负矩部分梁连续放置在码头(500)上。 铺设有护套管的预制地板(300)安装在负弯矩部分梁上。 将非附着钢丝(330)插入护套管中,然后拉紧以对预制地板施加压力。 混凝土在正向力矩梁的上部和腹部之间以及正向和反向力矩部件梁之间的连接部分上倾倒并硬化。
