Description

一种可提高建筑结构构件阻尼的预应力减震部件 A prestressed shock-absorbing component that can improve the damping of building structural components

技术领域technical field

本实用新型涉及建筑结构的阻尼减震控制和已有建筑物的抗震加固,尤其是置于结构构件中或附着于结构构件表面的阻尼抗震装置。 The utility model relates to the damping and shock-absorbing control of building structures and the seismic reinforcement of existing buildings, in particular to a damping and shock-resistant device placed in or attached to the surface of a structural component. the

背景技术Background technique

近年来我国连续发生了多次具有较大破坏力地震,其中汶川地震、玉树地震造成的生命和财产损失,举国为之同悲。我国大部分城市和重要工业建筑都位于地震区,地震危害将长期威胁着我们。因而减轻建筑结构在地震作用中发生破坏性损失具有重要的经济价值和社会意义。 In recent years, there have been many earthquakes with great destructive power in my country. Among them, the Wenchuan earthquake and Yushu earthquake caused the loss of life and property, and the whole country mourns for it. Most of my country's cities and important industrial buildings are located in earthquake zones, and earthquake hazards will threaten us for a long time. Therefore, it has important economic value and social significance to reduce the destructive loss of building structures in earthquake action. the

目前常用的减震技术主要是通过在建筑内部安装阻尼器。利用建筑物的层间位移驱动阻尼器工作,增加结构阻尼,从而达到减震的目的。在结构内部安装阻尼器存在如下缺陷:一是很多结构内部的阻尼器安装空间受限于建筑功能或美观方面的要求,往往没有足够或合适的安装空间;二是阻尼器一般需要定期的检查与维修,这增加了使用阻尼器的成本;三是安装阻尼器部位的节点需要专门设计,增加了设计工作量;四是阻尼器的设计和应用需要专门知识和技术,造成了一定的应用障碍;五是国内大型工程的减震设备多采用国外阻尼器,国内同类产品与之竞争尚存在一定的困难。这些因素阻碍了阻尼减震技术的在我国的推广应用。 The current commonly used shock absorption technology is mainly through the installation of dampers inside the building. The inter-story displacement of the building is used to drive the damper to work, increasing the structural damping, so as to achieve the purpose of shock absorption. There are the following defects in the installation of dampers inside the structure: first, the installation space of dampers inside many structures is limited by the requirements of architectural functions or aesthetics, and often there is not enough or suitable installation space; second, dampers generally require regular inspection and inspection. Maintenance, which increases the cost of using the damper; third, the nodes where the damper is installed need to be specially designed, which increases the design workload; fourth, the design and application of the damper requires specialized knowledge and technology, which has caused certain application obstacles; Fifth, foreign dampers are mostly used in the shock absorption equipment of domestic large-scale projects, and it is still difficult for similar domestic products to compete with them. These factors have hindered the popularization and application of damping shock absorption technology in our country. the

我国旧有工程的抗震加固普遍采用的方法有在构件表面加钢板或粘接碳纤维布,加钢板可以提高旧有建筑物构件的刚度,粘接碳纤维布则是可以提 高构件的强度,二者各有侧重点,但都不能提高结构的阻尼。 The commonly used methods for seismic reinforcement of old projects in my country include adding steel plates or bonding carbon fiber cloth to the surface of components. Adding steel plates can increase the stiffness of old building components, and bonding carbon fiber cloth can increase the strength of components. Each has its own focus, but none of them can improve the damping of the structure. the

发明内容Contents of the invention

本实用新型的目的在于解决现有建筑结构安装阻尼器的上述缺陷和抗震加固方法不能提高结构阻尼的缺陷,提出了一种可提高建筑结构构件阻尼的预应力减震部件,通过置入钢筋混凝土构件中或安装于钢筋混凝土构件表面或焊接于钢结构构件中来提高构件的阻尼,进而实现整个建筑物的减震或加固,其使用不受建筑物内部空间的限制,适用范围广泛,可以在任意钢筋混凝土构件和钢结构构件中采用。 The purpose of this utility model is to solve the above-mentioned defects of installing dampers in existing building structures and the defect that the seismic reinforcement method cannot improve structural damping. In the component or installed on the surface of reinforced concrete component or welded in the steel structure component to improve the damping of the component, and then realize the shock absorption or reinforcement of the whole building. Its use is not limited by the internal space of the building. It has a wide range of applications and can be used in It can be used in any reinforced concrete member and steel structure member. the

为了实现上述目的,本实用新型采取了如下技术方案: In order to achieve the above object, the utility model has taken the following technical solutions:

一种可提高建筑结构构件阻尼的预应力减震部件,包括预应力钢杆1、套管2、锚板3、张拉锚具4;其中:预应力钢杆1装入套管2内;预应力钢杆1的一端与锚板3相连,另一端伸入张拉锚具4中;锚板3和张拉锚具4锚固于结构构件中,为预应力张拉提供反力。在锚板3和张拉锚具4在构件中固定后张拉预应力。预应力张拉完成后预应力钢杆1处于拉应力状态。套管2的作用一方面在于当预应力减震部件埋置于钢筋混凝土结构构件时隔离预应力钢杆1与混凝土的粘接,以便于张拉预应力;另外一方面在于为预应力钢杆1受压时提供防屈曲约束。 A prestressed damping component capable of improving the damping of building structural components, comprising a prestressed steel rod 1, a sleeve 2, an anchor plate 3, and a tension anchor 4; wherein: the prestressed steel rod 1 is installed in the sleeve 2; One end of the prestressed steel rod 1 is connected to the anchor plate 3, and the other end extends into the tension anchor 4; the anchor plate 3 and the tension anchor 4 are anchored in the structural member to provide counter force for the prestressed tension. After the anchor plate 3 and the tension anchor 4 are fixed in the component, the tension is prestressed. After the prestressed stretching is completed, the prestressed steel rod 1 is in a state of tensile stress. On the one hand, the function of the sleeve 2 is to isolate the bond between the prestressed steel rod 1 and the concrete when the prestressed damping part is embedded in the reinforced concrete structural member, so as to facilitate the tension prestressing; 1 Provides anti-buckling restraint when in compression. the

一般来说可以将预应力减震部件安装于结构构件中纵向纤维受拉变形较大区域,如钢筋混凝土梁柱构件截面抗弯纵筋下面或钢结构受弯构件翼缘内侧或钢结构钢支撑截面中间部位。当结构构件发生振动时:如果构件中的预 应力减震部件处于受拉状态,则预应力减震部件中的预应力钢杆的拉应变将进一步增加,由于预应力的存在,使得预应力钢杆的拉应变远大于相同位置的结构配筋或钢材,因此预应力减震部件中的预应力钢杆将早于构件配筋或钢材进入屈服,提供滞回阻尼;上述预应力减震装置在构件截面中对称布置,则总有一侧处于受拉状态可以提供阻尼。本减震部件主要利用拉应力方向的塑性耗能。 Generally speaking, the prestressed shock absorbing components can be installed in the area where the longitudinal fiber is subjected to large tensile deformation in the structural member, such as under the bending longitudinal reinforcement of the reinforced concrete beam-column member section or inside the flange of the bending member of the steel structure or the steel support of the steel structure The middle part of the section. When the structural member vibrates: if the prestressed damping part in the member is in tension, the tensile strain of the prestressed steel rod in the prestressed damping part will further increase, due to the existence of prestress, the prestressed steel The tensile strain of the rod is much larger than the structural reinforcement or steel at the same position, so the prestressed steel rod in the prestressed shock absorbing part will enter yield earlier than the structural reinforcement or steel to provide hysteretic damping; the above prestressed shock absorbing device is in If the member is arranged symmetrically in the section, one side is always in tension to provide damping. The damping component mainly utilizes plastic energy dissipation in the direction of tensile stress. the

以上所述的结构构件包括:钢筋混凝土梁、柱、墙、板;钢骨混凝土柱、梁、墙;型钢一混凝土组合梁;钢梁、钢柱、钢板剪力墙、钢支撑。 The structural components mentioned above include: reinforced concrete beams, columns, walls, and slabs; steel-reinforced concrete columns, beams, and walls; steel-concrete composite beams; steel beams, steel columns, steel plate shear walls, and steel supports. the

预应力减震部件中的预应力钢1杆可以采用钢筋、钢管、钢棒 The prestressed steel 1 bar in the prestressed shock absorbing parts can use steel bars, steel pipes, steel rods

对于结构构件中受震变形大的区域可连续布置该装置,以有效的为结构和构件提供阻尼减震保护。 The device can be arranged continuously for areas with large seismic deformation in structural components to effectively provide damping and shock absorption protection for structures and components. the

本实用新型提出的可提高建筑结构构件阻尼的预应力减震部件可获得如下有益效果: The prestressed damping parts proposed by the utility model that can improve the damping of building structural members can obtain the following beneficial effects:

预应力减震部件安装于结构构件中,可以增加构件的阻尼水平,起到降低结构地震响应的效果; The prestressed damping components are installed in the structural components, which can increase the damping level of the components and reduce the seismic response of the structure;

预应力减震部件不占用建筑物内部的安装空间,可以在任意构件中使用,包括梁、柱、墙、板、支撑等,适用范围广泛。 Prestressed damping components do not occupy the installation space inside the building, and can be used in any component, including beams, columns, walls, panels, supports, etc., and have a wide range of applications. the

预应力减震部件用于抗震加固时,可直接安装于构件表面,施工方便,不影响建筑的正常使用功能。 When the prestressed shock-absorbing components are used for seismic reinforcement, they can be directly installed on the surface of the component, which is convenient for construction and does not affect the normal function of the building. the

预应力减震部件中的钢材为普通结构钢,工程造价低。 The steel in the prestressed damping part is common structural steel, and the engineering cost is low. the
