The assembly structure also includes guide grooves preset on the side surfaces of both ends of the shock-absorbing wall unit, the guide groove positions correspond to the positions of the guide bases and can be snapped into the guide bases, and the guide bases have a width smaller than the width of the wall and are located at the side widths of the columns. The middle position of the guide base in the horizontal direction, and the length of the outward bulge of the guide base in the horizontal direction is less than the depth of the guide groove, so that a post-pouring connection cavity is formed between each of the outer side surfaces of the front end and the outer sides of the two sides of the guide base and the guide groove, and the guide base The outer side of the front end and the outer sides of both sides are provided with a plurality of connecting steel bars extending outward into the post-pouring connection cavity, and the shock-absorbing wall unit is also provided with a vertical post-pouring channel on the upper end surface corresponding to the upper position of the guide groove. It is connected with the post-cast connection cavity; the cast-in-place assembly structure also includes a limit device, and the limit device includes a spring installation hole located on the upper end face of the guide base and vertically arranged, a coil spring is installed in the spring installation hole, and the coil spring installation hole orifice There is a limit ball with a diameter smaller than the diameter of the orifice. When the limit ball is not under pressure, the upper half of the limit ball is pushed out of the spring installation hole orifice by the coil spring, and the upper half of the limit ball is provided at the corresponding position on the top surface of the guide groove. Drop into the limit slot of the limit.
这样,装配时,引导底座预先安装固定在墙体两侧立柱内侧面上(优选为引导底座和立柱预先整体现浇固定为一体),然后将预制好的减震墙体单元竖立起并沿水平推动到安装位,使得引导底座对应卡入减震墙体单元两端侧面上的引导槽内,减震墙体单元推动到位后引导底座上端面的限位滚珠滚动落入到引导槽上顶面的限位槽中实现定位,然后在引导槽两侧支好浇筑模板,将混凝土从减震墙体单元上端面的竖向后浇孔道灌入并填充到后浇连接腔内,待养护凝固完毕,完成减震墙体单元和墙体两侧立柱之间的装配施工。故具有施工方便快捷,减震墙体单元和墙体两侧立柱连接稳定可靠等优点。In this way, during assembly, the guide base is pre-installed and fixed on the inner sides of the columns on both sides of the wall (preferably, the guide base and the column are pre-cast and fixed as a whole), and then the prefabricated shock-absorbing wall unit is erected and horizontally Push it to the installation position so that the guide base fits into the guide grooves on both sides of the shock-absorbing wall unit. After the shock-absorbing wall unit is pushed in place, the limit balls on the upper end of the guide base roll and fall into the top surface of the guide groove. Positioning is achieved in the limit groove of the wall, and then the pouring formwork is supported on both sides of the guide groove, and the concrete is poured from the vertical post-pouring channel on the upper end face of the shock-absorbing wall unit and filled into the post-pouring connection cavity, waiting for curing and solidification. , to complete the assembly construction between the shock-absorbing wall unit and the columns on both sides of the wall. Therefore, it has the advantages of convenient and quick construction, stable and reliable connection between the shock-absorbing wall unit and the columns on both sides of the wall.
作为优化,墙体两侧立柱内侧面上的引导底座沿竖向设置有多个。更好地提高连接可靠性。As an optimization, a plurality of guide bases are vertically arranged on the inner sides of the columns on both sides of the wall. Better connection reliability.
进一步地,所述减震墙体单元内部成形有竖向的安装腔,安装腔下端中部位置设置有质量块,质量块上端连接有吊绳并通过吊绳吊设在安装腔中,安装腔中位于质量块沿墙体长度方向的两端留有供质量块摆动的空间,还包括用于对质量块摆动方向提供反向作用力的阻尼构件。Further, a vertical installation cavity is formed inside the shock absorbing wall unit, a mass block is arranged in the middle of the lower end of the installation cavity, and a hanging rope is connected to the upper end of the mass block and is suspended in the installation cavity through the hanging rope. Spaces for the mass block to swing are reserved at both ends of the mass block along the length direction of the wall, and a damping member for providing a reverse force to the swing direction of the mass block is also included.
这样,当建筑受地震或风力影响而振动(摆动)时,质量块起到定心的作用减缓建筑上端的摆动作用,具体地说当建筑振动(摆动)时,质量块相对于建筑产生反向振动(摆动),抵消建筑的部分振动响应,减轻建筑的振动幅度。同时阻尼构件的存在和质量块构成调谐质量阻尼器,依靠阻尼构件和质量块的相互作用耗散转换一部分振动能量,极大地提高了减震效果。In this way, when the building is vibrated (swinged) by earthquake or wind, the mass block acts as a center to slow down the swinging effect of the upper end of the building. Specifically, when the building vibrates (swings), the mass block is reversed relative to the building. Vibration (swing), which offsets part of the building's vibration response and reduces the building's vibration amplitude. At the same time, the existence of the damping member and the mass block constitute a tuned mass damper, which relies on the interaction between the damping member and the mass block to dissipate and convert part of the vibration energy, which greatly improves the damping effect.
作为优化,所述安装腔包括下方的滑动槽和衔接在滑动槽上方的平面槽,所述质量块安装于滑动槽内,所述吊绳位于平面槽内,所述质量块宽度大于平面槽宽度。As an optimization, the installation cavity includes a sliding groove below and a flat groove connected above the sliding groove, the mass block is installed in the sliding groove, the hanging rope is located in the flat groove, and the width of the proof block is larger than the width of the flat groove .
这样,使得质量块被限位于滑动槽中滑动,避免从滑动槽中滑出,但墙体为预制式的装配式墙体时,更方便其运输和装配。In this way, the mass block is limited to slide in the sliding groove to avoid sliding out of the sliding groove, but when the wall is a prefabricated assembled wall, its transportation and assembly are more convenient.
作为优化,所述质量块整体呈圆形饼状。便于生产制造,利于被滑动槽限位。As an optimization, the mass block is in the shape of a circular pie as a whole. It is convenient for production and manufacture, and it is beneficial to be limited by the sliding groove.
作为优化,所述质量块采用钢板外壳内部灌铅制得。As an optimization, the mass block is made by filling lead inside the steel plate shell.
这样可以更好地提高重量,增强定心作用,增大摩擦阻尼,提高能量耗散转换效率,提高减震效果。In this way, the weight can be better increased, the centering effect can be enhanced, the friction damping can be increased, the energy dissipation conversion efficiency can be improved, and the shock absorption effect can be improved.
作为优化,所述滑动槽呈和质量块摆动路径一致的弧形。As an optimization, the sliding groove is in an arc shape consistent with the swing path of the mass block.
这样更加方便质量块在滑动槽内滑动。This is more convenient for the mass block to slide in the sliding groove.
作为优化,所述吊绳采用钢丝绳。保证具有足够的强度。As an optimization, the suspending rope adopts a steel wire rope. Guaranteed to have sufficient strength.
作为优化,所述安装腔上端水平设置有支撑梁,吊绳上端通过锚栓固定在支撑梁下表面。As an optimization, the upper end of the installation cavity is provided with a support beam horizontally, and the upper end of the suspending rope is fixed on the lower surface of the support beam through an anchor bolt.
这样,方便安装制造,且支撑梁可以更好地承受质量块的重量,保证整体结构稳定性。In this way, it is convenient to install and manufacture, and the support beam can better bear the weight of the mass block, so as to ensure the stability of the overall structure.
作为优化,支撑梁内设置有钢筋笼。更好地提高支撑梁强度,保证支撑可靠性。As an optimization, steel cages are arranged in the support beams. Better improve the strength of the support beam and ensure the support reliability.
作为优化,所述阻尼构件包括固定在质量块两侧的滑动槽内壁上的摩擦板,摩擦板由弹性材料制得,摩擦板表面为和质量块接触的摩擦面。As an optimization, the damping member includes a friction plate fixed on the inner walls of the sliding grooves on both sides of the mass block, the friction plate is made of elastic material, and the surface of the friction plate is a friction surface in contact with the mass block.
这样,采用弹性材料制得的摩擦板,使得质量块摆动时,既能够产生一个阻尼作用,又能够和质量块摩擦而将动能转换为内能耗散掉。同时使得阻尼作用效果能够方便调节大小,以更好地实现调谐质量阻尼器的效果。In this way, the friction plate made of elastic material can not only produce a damping effect when the mass block swings, but also can rub against the mass block to convert kinetic energy into internal energy and dissipate it. At the same time, the damping effect can be easily adjusted in size, so as to better realize the effect of the tuned mass damper.
作为优化,摩擦板厚度从滑动槽中部到两侧逐渐增大。As an optimization, the thickness of the friction plate gradually increases from the middle of the sliding groove to both sides.
这样使得摩擦板之间供质量块滑动的空间间隔宽度从中部到两侧逐渐减小,这样质量块在滑动槽中摆动时,所受阻尼作用能够随偏摆角度的增大而增大,故建筑受地震或者风力作用摆动时,摆动幅度越大,质量块受阻尼作用效果越大且质量块和摩擦板摩擦耗能转换效果越好,其转换耗能减震效果能够和建筑摆动幅度随动响应,起到最好的调谐质量阻尼器效果。In this way, the width of the space interval between the friction plates for the mass block to slide gradually decreases from the middle to the two sides, so that when the mass block swings in the sliding groove, the damping effect it receives can increase with the increase of the yaw angle. When the building is swayed by earthquake or wind, the larger the swing amplitude, the greater the damping effect of the mass block and the better the conversion effect of friction energy consumption between the mass block and the friction plate. Responsive to play the best tuned mass damper effect.
进一步地,减震墙体单元为整体对称设置的左半墙体和右半墙体对合固定得到,左半墙体和右半墙体的对合面上成形出安装腔,左半墙体和右半墙体对合后上端面形成支撑梁安装槽并用于安装支撑梁,支撑梁安装槽底中部留有向下连通到安装腔的吊绳孔供吊绳穿过,左半墙体和右半墙体周向上靠近边缘位置具有水平贯穿设置的水平后浇孔道,左半墙体和右半墙体依靠水平后浇孔道内浇筑的混凝土实现相对固定。Further, the shock absorbing wall unit is obtained by co-fixing the left half wall body and the right half wall body which are symmetrically arranged as a whole, an installation cavity is formed on the butting surface of the left half wall body and the right half wall body, and the left half wall body is formed. The upper end face of the right half wall forms a support beam installation groove and is used to install the support beam. The middle of the bottom of the support beam installation groove is left with a hanging rope hole that connects downward to the installation cavity for the hanging rope to pass through. The left half wall and The right half wall is provided with a horizontal post-casting channel arranged horizontally through the circumferential direction near the edge, and the left half-wall and the right half-wall are relatively fixed by the concrete poured in the horizontal post-pouring channel.
这样方便减震墙体单元的制备,利于内部减震结构的设置安装。具体地说,减震墙体单元可以采用以下步骤制备:a先单独支模并浇筑成形出左半墙体和右半墙体,左半墙体和右半墙体的对合面上成形出安装腔,安装腔下端成形出整体呈弧形且槽深变大的滑动槽,左半墙体和右半墙体对合后上端面形成支撑梁安装槽,左半墙体和右半墙体周向上靠近边缘位置具有水平贯穿设置的水平后浇孔道;b将摩擦板粘贴固定在滑动槽内;c将预制好的质量块置入到滑动槽中,固定在质量块上的吊绳拉出到支撑梁安装槽;d完成左半墙体和右半墙体的对合,在水平后浇孔道中浇筑混凝土实现固定;e将对合后的左半墙体和右半墙体保持竖直状态,在支撑梁安装槽中捆绑钢筋笼,将吊绳端部固定到钢筋笼上,完成支撑梁的浇筑。这样即可方便快捷可靠地预制形成减震墙体单元。In this way, the preparation of the shock-absorbing wall unit is facilitated, and the setting and installation of the internal shock-absorbing structure is facilitated. Specifically, the shock-absorbing wall unit can be prepared by the following steps: a. First, the left half wall and the right half wall are formed by separately supporting the formwork and pouring, and the left half wall and the right half wall are formed on the opposite surface of the left half wall and the right half wall. Installation cavity, the lower end of the installation cavity is formed with an arc-shaped sliding groove as a whole and the groove depth becomes larger. In the circumferential direction, there is a horizontal post-casting channel arranged horizontally through the edge; b. The friction plate is pasted and fixed in the sliding groove; c. The prefabricated mass block is placed in the sliding groove, and the hanging rope fixed on the mass block is pulled out. to the installation groove of the support beam; d Complete the alignment of the left half wall and the right half wall, and pour concrete in the horizontal post-pouring channel to achieve fixation; e keep the combined left half wall and right half wall vertical In this state, the reinforcement cage is bundled in the installation groove of the support beam, and the end of the suspending rope is fixed to the reinforcement cage to complete the pouring of the support beam. In this way, the shock-absorbing wall unit can be prefabricated easily, quickly and reliably.

这样,装配时,引导底座预先安装固定在墙体两侧立柱内侧面上(优选为引导底座和立柱整体现浇固定为一体),然后将预制好的减震墙体单元竖立起并沿水平推动到安装位,使得引导底座对应卡入减震墙体单元两端侧面上的引导槽内,减震墙体单元推动到位后引导底座上端面的限位滚珠滚动落入到引导槽上顶面的限位槽中实现定位,然后在引导槽两侧支好浇筑模板,将混凝土从减震墙体单元上端面的竖向后浇孔道灌入并填充到后浇连接腔内,待养护凝固完毕,完成减震墙体单元和墙体两侧立柱之间的装配施工。故具有施工方便快捷,减震墙体单元和墙体两侧立柱连接稳定可靠等优点。In this way, during assembly, the guide base is pre-installed and fixed on the inner sides of the columns on both sides of the wall (preferably, the guide base and the column are cast-in-place and fixed as a whole), and then the prefabricated shock-absorbing wall unit is erected and pushed horizontally. After the shock-absorbing wall unit is pushed in place, the limit balls on the upper end of the guide base roll and fall into the guide grooves on the top surface of the guide groove. The positioning is realized in the limit groove, and then the pouring formwork is supported on both sides of the guide groove, and the concrete is poured from the vertical post-pouring channel on the upper end face of the shock-absorbing wall unit and filled into the post-pouring connection cavity. After curing and solidification, Complete the assembly construction between the shock-absorbing wall unit and the columns on both sides of the wall. Therefore, it has the advantages of convenient and quick construction, stable and reliable connection between the shock-absorbing wall unit and the columns on both sides of the wall.
其中,墙体两侧立柱内侧面上的引导底座沿竖向设置有多个。更好地提高连接可靠性。Wherein, a plurality of guide bases are vertically arranged on the inner sides of the columns on both sides of the wall. Better connection reliability.
其中,所述减震墙体单元内部成形有竖向的安装腔,3,安装腔3下端中部位置设置有质量块1,质量块1上端连接有吊绳4并通过吊绳4吊设在安装腔中,安装腔中位于质量块沿墙体长度方向的两端留有供质量块摆动的空间,还包括用于对质量块摆动方向提供反向作用力的阻尼构件。Wherein, a vertical installation cavity is formed inside the shock absorbing wall unit; 3, a
这样,当建筑受地震或风力影响而振动(摆动)时,质量块起到定心的作用减缓建筑上端的摆动作用,具体地说当建筑振动(摆动)时,质量块相对于建筑产生反向振动(摆动),抵消建筑的部分振动响应,减轻建筑的振动幅度。同时阻尼构件的存在和质量块构成调谐质量阻尼器,依靠阻尼构件和质量块的相互作用耗散转换一部分振动能量,极大地提高了减震效果。In this way, when the building is vibrated (swinged) by earthquake or wind, the mass block acts as a center to slow down the swinging effect of the upper end of the building. Specifically, when the building vibrates (swings), the mass block is reversed relative to the building. Vibration (swing), which offsets part of the building's vibration response and reduces the building's vibration amplitude. At the same time, the existence of the damping member and the mass block constitute a tuned mass damper, which relies on the interaction between the damping member and the mass block to dissipate and convert part of the vibration energy, which greatly improves the damping effect.
其中,所述安装腔3包括下方的滑动槽和衔接在滑动槽上方的平面槽,所述质量块1安装于滑动槽内,所述吊绳4位于平面槽内,所述质量块宽度大于平面槽宽度。The
这样,使得质量块被限位于滑动槽中滑动,避免从滑动槽中滑出,但墙体为预制式的装配式墙体时,更方便其运输和装配。In this way, the mass block is limited to slide in the sliding groove to avoid sliding out of the sliding groove, but when the wall is a prefabricated assembled wall, its transportation and assembly are more convenient.
其中,所述质量块1整体呈圆形饼状。便于生产制造,利于被滑动槽限位。Wherein, the
其中,所述质量块采用钢板外壳内部灌铅制得。Wherein, the mass block is prepared by filling the inside of the steel shell with lead.
这样可以更好地提高重量,增强定心作用,增大摩擦阻尼,提高能量耗散转换效率,提高减震效果。In this way, the weight can be better increased, the centering effect can be enhanced, the friction damping can be increased, the energy dissipation conversion efficiency can be improved, and the shock absorption effect can be improved.
其中,所述滑动槽呈和质量块1摆动路径一致的弧形。Wherein, the sliding groove is in an arc shape consistent with the swing path of the
这样更加方便质量块在滑动槽内滑动。This is more convenient for the mass block to slide in the sliding groove.
其中,所述吊绳4采用钢丝绳。保证具有足够的强度。Wherein, the hanging
其中,所述安装腔3上端水平设置有支撑梁5,吊绳4上端通过锚栓固定在支撑梁5下表面。Wherein, the upper end of the
这样,方便安装制造,且支撑梁可以更好地承受质量块的重量,保证整体结构稳定性。In this way, it is convenient to install and manufacture, and the support beam can better bear the weight of the mass block, so as to ensure the stability of the overall structure.
其中,支撑梁5内设置有钢筋笼6。更好地提高支撑梁强度,保证支撑可靠性。Among them, a
其中,所述阻尼构件包括固定在质量块两侧的滑动槽内壁上的摩擦板,摩擦板由弹性材料制得并构成所述弹性材料层2,摩擦板表面为和质量块接触的摩擦面。The damping member includes friction plates fixed on the inner walls of the sliding grooves on both sides of the mass block. The friction plate is made of elastic material and constitutes the
这样,采用弹性材料制得的摩擦板,使得质量块摆动时,既能够产生一个阻尼作用,又能够和质量块摩擦而将动能转换为内能耗散掉。同时使得阻尼作用效果能够方便调节大小,以更好地实现调谐质量阻尼器的效果。In this way, the friction plate made of elastic material can not only produce a damping effect when the mass block swings, but also can rub against the mass block to convert kinetic energy into internal energy and dissipate it. At the same time, the damping effect can be easily adjusted in size, so as to better realize the effect of the tuned mass damper.
其中,摩擦板厚度从滑动槽中部到两侧逐渐增大。Among them, the thickness of the friction plate gradually increases from the middle of the sliding groove to both sides.
这样使得摩擦板之间供质量块滑动的空间间隔宽度从中部到两侧逐渐减小,这样质量块在滑动槽中摆动时,所受阻尼作用能够随偏摆角度的增大而增大,故建筑受地震或者风力作用摆动时,摆动幅度越大,质量块受阻尼作用效果越大且质量块和摩擦板摩擦耗能转换效果越好,其转换耗能减震效果能够和建筑摆动幅度随动响应,起到最好的调谐质量阻尼器效果。In this way, the width of the space interval between the friction plates for the mass block to slide gradually decreases from the middle to the two sides, so that when the mass block swings in the sliding groove, the damping effect it receives can increase with the increase of the yaw angle. When the building is swayed by earthquake or wind, the larger the swing amplitude, the greater the damping effect of the mass block and the better the conversion effect of friction energy consumption between the mass block and the friction plate. Responsive to play the best tuned mass damper effect.
