本专利涉及一种可恢复功能的装配式波浪腹板梁柱组合节点连接装置，属于结构工程技术领域。The patent relates to a recoverable fabricated wave web beam-column combined node connection device, which belongs to the technical field of structural engineering.
背景技术Background technique
改革开放以来，我国的城市发展取得了举世瞩目的成就。但城市建设仍属于以混凝土为主、现场砌筑的粗放型建造方式，造成了环境污染加剧，材料浪费严重，建造成本高，产品质量低等多方面的问题。2015年4月，《中共中央国务院关于加快推进生态文明建设的意见》要求全面促进资源节约循环高效使用，完善再生资源回收体系，推进建筑垃圾资源化利用，并大力推广绿色建筑，使建筑达到绿色、实用、经济、美观的标准。装配式钢结构作为全寿命周期的绿色建筑，具有标准化设计、工厂化生产、装配化施工、一体化装修，信息化管理等特点。大力推广装配式钢结构建筑，可以减少建筑垃圾和建筑扬尘污染，缩短建造工期，提升工程质量，消化钢铁过剩产能，形成钢材战略储备。目前，装配式钢结构建筑体系已成为建筑钢结构发展的新方向和新趋势。Since the reform and opening up, my country's urban development has made remarkable achievements. However, urban construction is still an extensive construction method based on concrete and on-site masonry, which has caused aggravated environmental pollution, serious waste of materials, high construction costs, and low product quality. In April 2015, the "Opinions of the Central Committee of the Communist Party of China and the State Council on Accelerating the Construction of Ecological Civilization" required comprehensive promotion of resource conservation, recycling and efficient use, improvement of the recycling system of renewable resources, promotion of resource utilization of construction waste, and vigorous promotion of green buildings to make buildings green , Practical, economical and beautiful standards. As a green building with a full life cycle, the prefabricated steel structure has the characteristics of standardized design, factory production, assembly construction, integrated decoration, and information management. Vigorously promoting prefabricated steel structure buildings can reduce construction waste and construction dust pollution, shorten the construction period, improve project quality, digest excess steel production capacity, and form a strategic steel reserve. At present, the prefabricated steel structure building system has become a new direction and new trend in the development of building steel structures.
波浪腹板工形构件作为一种节能、节材、绿色环保的新型钢结构构件，在国内外工程领域已被广泛应用。波浪腹板工形构件由正弦形波浪腹板与平直翼缘通过高频连续焊接组成，可替代传统的普通焊接H型钢、工字钢等。它与传统的平腹板工形构件相比不仅节省了材料、减轻了自身重量，还提高了工形构件的面外抗弯刚度与扭转刚度，能够保证构件在超过高宽比的限值时，构件仍能满足在制作、运输及安装过程中的刚度要求，减少了因构件腹板刚度不足给施工带来的不便。As a new energy-saving, material-saving, green and environmentally friendly steel structure member, the corrugated web I-shaped member has been widely used in engineering fields at home and abroad. The corrugated web I-shaped member is composed of sinusoidal corrugated web and straight flange through high-frequency continuous welding, which can replace the traditional ordinary welded H-beam and I-beam. Compared with the traditional flat-web I-shaped member, it not only saves materials and reduces its own weight, but also improves the out-of-plane bending stiffness and torsional stiffness of the I-shaped member, which can ensure that when the member exceeds the limit of the aspect ratio , the components can still meet the rigidity requirements in the process of fabrication, transportation and installation, which reduces the inconvenience to construction caused by insufficient stiffness of the component web.
梁柱节点设计不合理将导致“强构件弱节点”情况的发生，使结构在地震荷载作用下发生严重震害，威胁人民生命财产安全。现有研究表明，对梁柱节点进行针对性加强或对梁上特定区域采取如设置狗骨削弱区等削弱手段可达到塑性铰外移的目的，从而保护梁柱节点，满足“强节点弱构件”的设计要求；同时，楼板与梁段预组装后运至施工现场进行拼装可大大节省现场混凝土浇筑的时间，但楼板组合效应使梁柱节点承载力和刚度有一定程度提升的同时，也会降低节点转动能力，还可能导致“强梁弱柱”情况的发生，这将与设计初衷相违背，因此需针对组合结构特点进行针对性设计，以在充分发挥其优势的同时保证结构各项性能；此外，地震后无需修复或稍加修复即可恢复使用功能的可恢复功能结构是近年来国际地震工程领域的研究热点，不仅能够在地震中保护人们的生命财产安全，而且在地震后也能尽快恢复其使用功能，因此亟需将可恢复功能结构的理念落实于新结构的研发设计工作中，以实现建筑从单一追求抗倒塌能力向兼顾震后可修复能力的转变。为满足以上需求，本发明专利提出了一种可恢复功能的装配式波浪腹板梁柱组合节点连接装置。The unreasonable design of beam-column joints will lead to the occurrence of "strong components and weak joints", which will cause serious earthquake damage to the structure under the action of earthquake load, threatening the safety of people's lives and properties. Existing studies have shown that targeted strengthening of beam-column joints or weakening measures such as setting dog-bone weakening areas on specific areas of beams can achieve the purpose of moving plastic hinges outward, thereby protecting beam-column joints and meeting the requirements of "strong joints and weak members". At the same time, the pre-assembled floor and beam sections can be transported to the construction site for assembly, which can greatly save the time of concrete pouring on site, but the combination effect of the floor will increase the bearing capacity and stiffness of the beam-column joints to a certain extent, and will also Reducing the rotation capacity of joints may also lead to the occurrence of "strong beams and weak columns", which will be contrary to the original intention of the design. Therefore, it is necessary to carry out targeted design according to the characteristics of the combined structure, so as to ensure the performance of the structure while giving full play to its advantages; In addition, the recoverable functional structure that can restore the function without repair or minor repair after the earthquake has become a research hotspot in the field of international earthquake engineering in recent years. To restore its use function, it is urgent to implement the concept of recoverable functional structure in the research and development and design of new structures, so as to realize the transformation of buildings from the single pursuit of collapse resistance to the consideration of post-earthquake repairability. In order to meet the above requirements, the patent of the present invention proposes a recoverable prefabricated corrugated web beam-column combined node connection device.

本专利的优点主要表现在以下几个方面：The advantages of this patent are mainly manifested in the following aspects:
1、不仅能够适应现行的装配式钢结构体系，并且可以通过拼接节点设计较弱与增加环形隔板的厚度共同作用而达到结构耗能与塑性铰外移的目的，而无需采取加设盖板、加劲肋及边板等梁端加强措施，降低了施工难度，避免了多条焊缝的复杂应力场。1. Not only can it adapt to the current prefabricated steel structure system, but also can achieve the purpose of structural energy consumption and plastic hinge outward movement through the combined effect of weak splicing joint design and increasing the thickness of the annular diaphragm, without the need for additional cover plates Beam end strengthening measures such as stiffeners, stiffeners and side plates reduce the difficulty of construction and avoid the complex stress field of multiple welds.
2、悬臂梁段与普通梁段的上下翼缘均采用翼缘单盖板的连接方式，故可先将下翼缘连接板与下部环形隔板通过螺栓连接，此时波浪腹板工形组合梁段可搭在带悬臂梁段圆钢管柱下翼缘外伸连接板上，降低了吊装难度，加快了施工进度，且拼装处台阶式构造使波浪腹板工形组合梁段放置到位后与悬臂梁段互相咬合，易于现场拼装定位。2. Both the upper and lower flanges of the cantilever beam section and the ordinary beam section adopt the connection method of flange single cover plate, so the lower flange connecting plate and the lower annular partition can be connected by bolts first, and the corrugated web plate I-shaped combination The beam section can be placed on the outrigger connecting plate of the lower flange of the circular steel pipe column with the cantilever beam section, which reduces the difficulty of hoisting and speeds up the construction progress, and the stepped structure of the assembly place enables the wave web I-shaped composite beam section to be placed in place and cantilever beam The segments interlock with each other, making it easy to assemble and position on site.
3、此节点可对连接板厚度、螺栓及狗骨削弱区布设方式等进行针对性设计，一方面可提高节点的延性以及转动能力，并保证节点有良好的耗能能力，在大震时可以确保建筑不发生倒塌，从而保护人员的生命财产安全；另一方面可使地震荷载作用下结构的破坏位置发生在易于更换的高强螺栓及下翼缘连接板等耗能构件处，确保带悬臂梁段圆钢管柱及中间梁段无损坏或轻微损坏，震后只需更换连接板和高强螺栓即可达到震后可恢复功能的效果。3. This node can be designed specifically for the thickness of the connecting plate, the layout of the bolt and the weakened area of the dog bone, etc. On the one hand, it can improve the ductility and rotation capacity of the node, and ensure that the node has a good energy dissipation capacity. To ensure that the building does not collapse, so as to protect the safety of personnel's life and property; on the other hand, the damage of the structure under the earthquake load can occur at the easily replaceable high-strength bolts and energy-consuming components such as the lower flange connecting plate, ensuring that the cantilever beam section is round The steel pipe column and the intermediate beam section are not damaged or slightly damaged. After the earthquake, only the connecting plate and high-strength bolts need to be replaced to achieve the effect of recoverable function after the earthquake.
