Description
技术领域technical field
本发明涉及一种应用在建筑工程结构领域中的预制装配式防屈曲钢板剪力墙及其施工方法，该发明尤其适用于高烈度设防地震区的装配式建筑。The invention relates to a prefabricated buckling-resistant steel plate shear wall applied in the field of building engineering structures and a construction method thereof, and the invention is especially suitable for assembled buildings in high-intensity fortification earthquake areas.
背景技术Background technique
钢板剪力墙是一种新型高效的抗侧力构件，与传统的钢筋混凝土剪力墙相比，具有承载力高、自重小、延性好、抗震性能优越等特点，尤其适用于高烈度抗震设防地区。Steel plate shear wall is a new type of high-efficiency anti-lateral force component. Compared with traditional reinforced concrete shear wall, it has the characteristics of high bearing capacity, small dead weight, good ductility, and superior seismic performance. It is especially suitable for high-intensity seismic fortification area.
目前，防屈曲薄钢板剪力墙应用广泛，但也面临一些问题需进一步解决：首先，钢板剪力墙根据与边缘构件连接情况的不同分为四边或两边连接钢板剪力墙；四边连接钢板剪力墙性能优越，但不利于电梯井、门窗以及过道的布置，同时还会对框架柱产生较大的附加内力；而两边连接防屈曲钢板剪力墙虽便于门窗、过道等洞口的布置，但内嵌钢板由于两侧边没有边缘构件的约束，导致内嵌钢板的性能不能充分发挥，钢板的四个角部应力集中，容易提早发生钢板撕裂，承载力和抗震性能较四边连接防屈曲钢板剪力墙低，因此两边连接钢板剪力墙的性能亟待改善。其次，钢板剪力墙与边缘构件的连接目前大多通过鱼尾板焊接实现，使得现场施工需较多的现场施焊，焊缝质量不易控制并且影响施工效率，阻碍了其在装配式建筑中的应用；并且，焊缝周围区域的残余应力会导致钢板剪力墙性能降低；同时，已有地震调查研究表明焊缝连接易在地震作用下发生脆性破坏，造成建筑严重破坏，不利于震后修复。因此，如上所述钢板剪力墙在连接构造和施工技术方面均面临着亟待进一步改善的问题。At present, buckling-resistant thin steel plate shear walls are widely used, but there are still some problems that need to be further solved: First, steel plate shear walls are divided into four-sided or two-sided connected steel plate shear walls according to the connection with edge members; four-sided connected steel plate shear walls The force wall has superior performance, but it is not conducive to the layout of elevator shafts, doors, windows, and aisles, and it will also generate a large additional internal force on the frame column; while the buckling-resistant steel plate shear wall connected on both sides is convenient for the layout of doors, windows, aisles, etc. Since the embedded steel plate is not constrained by the edge members on both sides, the performance of the embedded steel plate cannot be fully exerted. The stress concentration at the four corners of the steel plate is prone to early tearing of the steel plate. The shear wall is low, so the performance of the steel plate shear wall connected on both sides needs to be improved urgently. Secondly, the connection between the steel plate shear wall and the edge members is mostly realized by welding fishplates, which requires more on-site welding for on-site construction, and the quality of the welds is not easy to control and affects the construction efficiency, which hinders its application in prefabricated buildings. In addition, the residual stress in the area around the weld will reduce the performance of the steel plate shear wall; at the same time, existing seismic investigations have shown that the weld connection is prone to brittle failure under earthquake action, causing serious damage to the building, which is not conducive to post-earthquake repairs . Therefore, as mentioned above, the steel plate shear wall is facing problems that need to be further improved in terms of connection structure and construction technology.

(3)定位安装左、右钢管混凝土边柱3，其侧边焊接的柱连接件5与内嵌钢板9通过高强螺栓8连接，左、右钢管混凝土柱边柱3上、下端的连接板6与上、下框架梁1通过高强螺栓8连接；(3) Position and install the left and right concrete-filled steel pipe side columns 3, the column connectors 5 welded on the sides and the embedded steel plates 9 are connected by high-strength bolts 8, and the connecting plates 6 at the upper and lower ends of the left and right steel tube concrete-filled column side columns 3 Connect with the upper and lower frame beams 1 through high-strength bolts 8;
(4)最后在内嵌钢板9的两侧定位安装钢筋混凝土盖板10，以限制内嵌钢板的平面外变形，形成防屈曲钢板剪力墙13，钢筋混凝土盖板10与内嵌钢板9通过高强螺栓8连接。(4) Finally, the reinforced concrete cover plate 10 is positioned and installed on both sides of the embedded steel plate 9 to limit the out-of-plane deformation of the embedded steel plate to form a buckling-resistant steel plate shear wall 13, and the reinforced concrete cover plate 10 and the embedded steel plate 9 pass through High-strength bolt 8 connection.
如图6所示，在地震灾害作用下，装配式防屈曲钢板剪力墙可作为第一道抗震防线，通过内嵌钢板9的屈服进行耗能减震。地震后，只有内嵌钢板9和钢板混凝土盖板10发生损坏时，可对建筑结构进行快速修复：只需拧开内嵌钢板9与上、下梁连接件4之间的高强螺栓8以及内嵌钢板9与左、右柱连接件5之间的高强螺栓8，将损坏的防屈曲钢板墙14拆下，最后再将内嵌钢板9和钢筋混凝土盖板10预制成的新的防屈曲钢板墙13安装好即可。As shown in Figure 6, under the action of earthquake disasters, the prefabricated anti-buckling steel plate shear wall can be used as the first line of anti-seismic defense, and the energy dissipation and shock absorption can be performed through the yield of the embedded steel plate 9. After the earthquake, only when the embedded steel plate 9 and the steel plate concrete cover 10 are damaged, the building structure can be repaired quickly: only need to unscrew the high-strength bolts 8 between the embedded steel plate 9 and the upper and lower beam connectors 4 and the inner The high-strength bolts 8 between the embedded steel plate 9 and the left and right column connectors 5, remove the damaged buckling-resistant steel plate wall 14, and finally prefabricate the new buckling-resistant steel plate 9 and reinforced concrete cover plate 10 Steel plate wall 13 is installed and gets final product.
如图7所示，当地震作用较大时，内嵌钢板9、钢筋混凝土盖板10以及钢管混凝土边柱3都发生损坏时，同样可以对建筑结构进行快速修复：将内嵌钢板9与上、下梁连接件4连接的高强螺栓8以及左、右钢管混凝土边柱3的上、下连接板与框架梁1相连接的高强螺栓8拧开，拆下损坏的左、右钢管混凝土边柱15以及损坏的防屈曲钢板墙14，最后再将新的钢管混凝土边柱3和新的防屈曲钢板墙13按照步骤(1)、(2)、(3)、(4)重新连接，即可修复。As shown in Figure 7, when the earthquake action is large, when the embedded steel plate 9, the reinforced concrete cover plate 10 and the steel pipe concrete side column 3 are all damaged, the building structure can also be quickly repaired: the embedded steel plate 9 and the upper Unscrew the high-strength bolts 8 connected to the lower beam connector 4 and the high-strength bolts 8 connecting the upper and lower connecting plates of the left and right steel pipe concrete side columns 3 to the frame beam 1, and remove the damaged left and right steel pipe concrete side columns 15 and the damaged buckling-resistant steel plate wall 14, and finally reconnect the new steel pipe concrete side column 3 and the new buckling-resistant steel plate wall 13 according to steps (1), (2), (3) and (4), then repair.
