Description

预制装配式双钢板混凝土剪力墙连接组件及其使用方法Prefabricated double steel plate concrete shear wall connection assembly and method of use 技术领域Technical field
本发明涉及一种预制装配式双钢板混凝土剪力墙连接组件及其使用方法，属于建筑技术领域。The invention relates to a prefabricated double steel plate concrete shear wall connecting component and a method for using the same, belonging to the technical field of construction.
背景技术Background technique
装配式双钢板剪力墙结构较现浇剪力墙结构建造方式更能节约能源和材料，缩短工期，具有广泛的发展空间。The assembled double steel plate shear wall structure can save energy and materials more than the cast-in-place shear wall structure construction method, shorten the construction period, and has a wide development space.
目前，预制装配式剪力墙结构竖向连接形式分为湿式连接和干式连接两类。湿式连接主要包括现浇带连接、套筒灌浆连接、预留孔浆锚搭接等。现浇带连接具有以下明显缺点：在施工过程中上部墙体难以固定，连接时为100％同截面搭接；现浇带顶面的混凝土难以浇筑密实。套筒灌浆连接和预留孔浆锚搭接应用相对较广，但存在套筒及预留孔较粗、保护层厚度过小缺点。此外，前者对灌浆料的要求较高，工程中常用的清水混凝土难以满足要求；后者若在不太厚的墙体中预留大量插孔，施工难度大，运输过程中孔洞易损坏，影响构件的连接性能。At present, the vertical connection forms of prefabricated shear wall structures are divided into two types: wet connection and dry connection. Wet connection mainly includes cast-in-place belt connection, sleeve grouting connection, reserved hole slurry anchor lap and so on. The connection of the cast-in-place belt has the following obvious disadvantages: the upper wall is difficult to be fixed during the construction process, and the connection is 100% overlapped with the cross-section; the concrete on the top surface of the cast-in-place belt is difficult to pour and compact. The sleeve grouting connection and the reserved hole slurry anchor overlap are relatively widely used, but there are disadvantages that the sleeve and the reserved hole are thick and the thickness of the protective layer is too small. In addition, the former has high requirements for grouting, and it is difficult to meet the requirements of the common concrete used in the project; if the latter reserves a large number of sockets in the wall that is not too thick, the construction is difficult, and the holes are easily damaged during transportation. Component connection performance.
干式连接主要包括螺栓连接、键槽连接等，目前应用并不广泛。纯螺栓连接螺栓在动载下易发生松动、脱落等现象，其耐久性和可靠性难以达到标准。键槽连接性能较好，但主要用于装配式大板结构中。Dry connection mainly includes bolt connection, keyway connection, etc., which is not widely used at present. Pure bolt connection bolts are prone to loosening and falling off under dynamic load, and their durability and reliability are difficult to meet the standards. The keyway connection performance is better, but it is mainly used in the assembled large plate structure.
此外，装配式双钢板剪力墙常用于高层和超高层结构当中，其竖向连接较普通装配式混凝土剪力墙需要更高的抗剪能力。现有的连接方式难以满足要求。In addition, prefabricated double steel plate shear walls are often used in high-rise and super high-rise structures, and their vertical connection requires higher shear resistance than ordinary prefabricated concrete shear walls. The existing connection method is difficult to meet the requirements.
发明内容Summary of the invention

The design idea of “bending, shearing groove and shearing resistance”, the shearing groove and the shearing key strengthen the shearing performance of the connecting piece, the degree of assembly is high, the operation is simple, and the connection quality is reliable.

The concrete in the wall is poured through pouring holes.
所述顶板和底板分别位于墙体顶部和底部，起到连接上下墙体和墙体封口的作用。The top plate and the bottom plate are located at the top and bottom of the wall, respectively, and serve to connect the upper and lower walls and the wall seal.

The internal bearing arrangement of the bolt is to make a triangular prismatic groove in the steel plate at the corresponding position of the upper and lower walls, and arrange the bolt in the triangular prismatic groove to complete the connection of the bolt inside the wall section, so as to assemble The rear wall section is regular and easy to assemble.

本发明适用于双钢板混凝土剪力墙的竖向连接，尤其可以应用于设置阻尼夹层的双钢板混凝土剪力墙的竖向连接，进一步的，还可以应用于设置外包混凝土层阻尼夹层双钢板混凝土剪力墙的竖向连接，该墙体填充阻尼布置灵活，可以较好的与本组件协同使用。The invention is applicable to the vertical connection of a double steel plate concrete shear wall, and is particularly applicable to the vertical connection of a double steel plate concrete shear wall with a damping interlayer. Further, the invention can also be applied to the setting of an outer concrete layer damping interlayer double steel plate concrete The vertical connection of the shear wall, the wall filling and damping arrangement is flexible, and can be used in conjunction with this component.
如图6-7所示，所述外包混凝土层阻尼夹层双钢板混凝土剪力墙，包括由内向外依次为混凝土核心层、钢板层、阻尼夹层、外包混凝土层，所述钢板层两侧分别连接有钢管混凝土束，钢板层与钢管混凝土束之间浇筑有混凝土核心，所述外包承压不受拉混凝土内嵌阻尼夹层的双钢板组合剪力墙还包括分别连接于墙体顶部和底部的顶板和底板。As shown in Fig. 6-7, the double-concrete shear wall with double-steel-concrete layer and damping interlayer includes concrete core layer, steel plate layer, damping interlayer and over-concrete layer from the inside to the outside. There is a concrete-filled steel tube bundle, a concrete core is poured between the steel plate layer and the concrete-filled steel tube bundle, and the double-steel composite shear wall with the outsourcing pressure-retaining concrete embedded damping interlayer also includes roof plates connected to the top and bottom of the wall, respectively And bottom plate.
所述钢板层包括两片相平行的钢板。所述阻尼夹层包括两片平行的阻尼夹层，阻尼夹层位于钢板层和外包混凝土层之间。所述外包混凝土层包括两片相平行的混凝土层，分别外包于两片阻尼夹层。The steel plate layer includes two parallel steel plates. The damping interlayer includes two parallel damping interlayers, and the damping interlayer is located between the steel plate layer and the overwrap concrete layer. The enveloped concrete layer includes two parallel concrete layers, which are respectively enveloped by two damping interlayers.
所述外包承压不受拉混凝土内嵌阻尼夹层的双钢板组合剪力墙由约束拉杆组件连接而成。The double-steel composite shear wall of the outsourcing bearing pressure-free concrete embedded damping interlayer is formed by connecting tie rod assemblies.
所述外包混凝土层包括若干个外包钢筋混凝土层单元，外包钢筋混凝土 层单元角部为倒圆角结构。The enveloped concrete layer includes several enveloped reinforced concrete layer units, and the corners of the enveloped reinforced concrete layer unit are rounded.
外包钢筋混凝土层单元采用抗压不受拉设计，即在每个外包混凝土层单元的四个角部采用倒圆角设计，所述外包混凝土层单元与钢管混凝土束之间和相邻外包混凝土层单元之间留有空隙，并填充阻尼材料。这样的设计使得外包混凝土层不与两侧的钢管混凝土束直接连接，且顶部和底部外包混凝土层有着较小的截面面积，使其不直接承受水平荷载，不会产生或产生较小的水平向的拉压变形；进而使外包混凝土层只承受竖向荷载，较大的提升了墙体的竖向承载力和抗震性能。The outer reinforced concrete layer unit adopts the design of compressive and non-tensile, that is, the four corners of each outer concrete layer unit are rounded, and between the outer concrete layer unit and the concrete-filled steel tube bundle and the adjacent outer concrete layer There are gaps between the elements and they are filled with damping material. This design makes the outer concrete layer not directly connected to the concrete-filled steel tube bundles on both sides, and the top and bottom outer concrete layer has a smaller cross-sectional area, so that it does not directly bear the horizontal load, and will not produce or produce a small horizontal direction. The tensile and compression deformation of the wall; thus, the outer concrete layer can only bear the vertical load, which greatly improves the vertical bearing capacity and seismic performance of the wall.
所述钢管混凝土束包括六个钢管混凝土束单元，墙体两侧各三个。The concrete-filled steel tube bundle includes six concrete-filled steel tube bundle units, three on each side of the wall.
所述钢管混凝土束为墙体边缘约束构件，由型钢和浇筑其中的混凝土构成，单个钢管混凝土束单元厚度与墙体等厚，方便墙体装配化施工；在平面外伸出的另外四个钢管混凝土束单元，提高了墙体的抗弯、抗扭刚度和整体稳定性。The concrete-filled steel tube bundle is a wall edge-constraining member, which is composed of steel sections and concrete poured into it. The thickness of a single concrete-filled steel tube bundle unit is equal to that of the wall body, which is convenient for assembly of the wall body; another four steel pipes protruding out of the plane The concrete beam unit improves the bending resistance, torsional rigidity and overall stability of the wall.
所述阻尼夹层和填充的阻尼材料为高阻尼橡胶材料或泡沫铝材料。The damping interlayer and the filled damping material are high-damping rubber materials or aluminum foam materials.
所述阻尼夹层厚度为10～20mm。利用橡胶材料的滞回耗能，将结构振动产生的机械能转化成内能，从而减小结构的动力响应，同时增大了墙体平面外抗爆抗冲击性能。The thickness of the damping interlayer is 10-20 mm. Using the hysteretic energy dissipation of the rubber material, the mechanical energy generated by the structural vibration is converted into internal energy, thereby reducing the dynamic response of the structure and increasing the anti-blast and impact resistance of the wall outside the plane.
所述填充阻尼材料，一方面，可以避免相邻外包混凝土层单元之间、外包混凝土层和钢管混凝土束之间的直接接触，使外包混凝土层不直接受水平荷载，即减少水平向拉力对其影响。另一方面，填充阻尼也可发挥其阻尼作用，减小墙体在地震或爆炸作用下的反应。另外，填充阻尼布置灵活，若需在顶板和底板布置螺栓来连接上下两片墙体，可先布置螺栓，再在剩余空隙 用阻尼材料填充。The filling damping material, on the one hand, can avoid direct contact between adjacent outer-concrete layer units, between the outer-concrete layer and the concrete-filled steel tube bundle, so that the outer-concrete layer is not directly subjected to horizontal loads, that is, the horizontal tensile force is reduced. influences. On the other hand, filled damping can also exert its damping effect, reducing the wall response under earthquake or explosion. In addition, the filling and damping arrangement is flexible. If bolts are needed on the top and bottom plates to connect the upper and lower walls, the bolts can be arranged first, and then the remaining gaps are filled with damping materials.
所述钢板层对应位置开设若干个螺栓孔，约束拉杆组件通过螺栓孔穿过钢板层，采用螺栓锚固连接。A plurality of bolt holes are opened at corresponding positions of the steel plate layer, and the binding rod assembly is restricted to pass through the steel plate layer through the bolt holes and bolted to connect.
所述约束拉杆组件包括约束拉杆和若干螺帽，约束拉杆尺寸与钢板层开设的洞口大小相匹配。约束拉杆间距不超过100mm，长度为钢板层两片钢板间距+两侧外包混凝土层厚度-混凝土保护层厚度,混凝土保护层厚度为30mm左右，即拉杆在厚度方向延伸至外包混凝土层之中，与外包混凝土层中的钢筋网焊接，形成钢筋笼，增强墙体整体性。The constraining tie rod assembly includes a constraining tie rod and a number of nuts, and the size of the constraining tie rod matches the size of the opening in the steel plate layer. The spacing of the constraining tie rods does not exceed 100mm, the length is the distance between the two steel plates of the steel sheet layer + the thickness of the outer concrete layer on both sides-the thickness of the concrete protective layer, the thickness of the concrete protective layer is about 30mm, that is, the tie rod extends into the outer concrete layer in the thickness direction, and The reinforcement mesh in the outer concrete layer is welded to form a reinforcement cage, which enhances the integrity of the wall.
所述顶板和底板为钢板，厚度为25-35mm，优选30mm。顶板和底板与外包混凝土层直接接触。目的是将竖向荷载传至外包混凝土层，发挥外包混凝土层抗压性能。此外，顶板和底板在起到封顶和封底的作用的同时，标准化的钢板也有利于墙体间的连接和装配。The top plate and the bottom plate are steel plates with a thickness of 25-35mm, preferably 30mm. The top and bottom plates are in direct contact with the outer concrete layer. The purpose is to transfer the vertical load to the enveloped concrete layer and exert the compressive performance of the enveloped concrete layer. In addition, while the top plate and bottom plate play the role of capping and bottom sealing, standardized steel plates are also conducive to the connection and assembly between the walls.
使用本发明所述的连接组件进行竖向连接，可以弥补内嵌阻尼夹层所带来的承载力下降的缺陷，提高抗剪承载力。The vertical connection using the connection assembly of the present invention can make up for the defect of reduced bearing capacity caused by the embedded damping interlayer, and improve the shear bearing capacity.
