Description

一种保温减震屋盖A heat-insulating and shock-absorbing roof

技术领域：Technical field:

本发明涉及一种保温减震屋盖，属于工程结构减震领域及工程节能减排领域。The invention relates to a thermal insulation and shock absorption roof, which belongs to the fields of engineering structure shock absorption and engineering energy saving and emission reduction.

背景技术：Background technique:

现有屋面保温材料采用聚苯板等，其保温性能不理想且防火性能差，常因为施工不当导致聚苯板燃烧，造成巨大的经济损失和人员伤亡，市场亟待出现一种既轻质高强，又能防止火灾发生的屋面保温材料。加入稻草板的保温减震屋盖由于阻燃性能好、导热系数低的特点，解决了当前屋面保温性能差的弊端。Existing roof insulation materials use polystyrene boards, etc., which have unsatisfactory thermal insulation performance and poor fireproof performance. The polystyrene boards are often burned due to improper construction, causing huge economic losses and casualties. The market urgently needs a light-weight, high-strength, It is also a roof insulation material that can prevent fires. The heat-insulation and shock-absorbing roof with straw board has good flame retardancy and low thermal conductivity, which solves the disadvantages of poor heat preservation performance of the current roof.

现有的钢筋混凝土框架结构，因为抗侧刚度较小，在地震作用下结构顶点位移及结构顶层加速度反应较大，不仅限制了框架结构向高层方向发展的步伐，而且使居住在顶层的舒适度下降，为了解决上述问题，利用非线性减震器作为层间减震器，迅速俘获地震优势频率并发生类共振，将地震能量转移并消耗，减轻结构地震反应及震害。若顶部安装有空腹夹层板屋盖，则非线性减震器还将起到保护剪力键及柱节点，避免通过剪力键及柱节点的塑性破坏消耗地震能量导致整体屋盖的破坏，更大程度的减轻屋顶地震反应。The existing reinforced concrete frame structure, because of the small lateral stiffness, the top displacement of the structure and the acceleration response of the top floor of the structure are relatively large under the action of earthquakes, which not only limits the development of the frame structure to the high-rise direction, but also makes living on the top floor more comfortable. In order to solve the above problems, the nonlinear shock absorber is used as the interstory shock absorber to quickly capture the dominant frequency of the earthquake and generate a quasi-resonance, transfer and consume the seismic energy, and reduce the seismic response and earthquake damage of the structure. If there is an empty-web sandwich panel roof installed on the top, the nonlinear shock absorber will also protect the shear keys and column joints, avoiding the damage of the overall roof due to the consumption of seismic energy through the plastic failure of the shear keys and column joints, and the greater Minimize the seismic response of the roof.

实施例2：Example 2:

上述保温减震屋盖，首先进行钢筋混凝土空腹夹层板屋盖结构施工，空腹夹层板屋盖下肋10、空腹夹层板屋盖剪力键8、空腹夹层板屋盖上肋7及空腹夹层板屋盖结构层6钢筋绑扎完成并与柱钢筋可靠连接成一体，后将模板支撑在钢筋外部并保证足够厚度的保护层厚度，整体浇筑混凝土，待强度达到28天强度后，再进行屋面各层铺设；铺设至加入阻燃剂的稻草板保温层4时，应将混凝土找坡层5上侧应干燥，并经过处理达到平整、干净，再将硅酮结构胶涂刷在混凝土找坡层5上，粘贴之前应对硅酮结构胶和加入阻燃剂的稻草板保温层4做相容性侧试，合格后方可将加入阻燃剂的稻草板保温层4粘贴在混凝土找坡层5上侧，相邻稻草板之间应错缝拼接；加入阻燃剂的稻草板保温层4上侧应做界面处理，保证加入阻燃剂的稻草板保温层不受外部水分侵害，在加入阻燃剂的稻草板保温层4上侧涂刷界面剂，待干燥后进行水泥砂浆找平层3浇筑，加入阻燃剂的稻草板保温层4在制作时应添加30％防火阻燃剂；与此同时，将减震器钢滑道11通过螺栓固定在空腹夹层板屋盖下肋10上侧，螺栓应不妨碍上侧非线性减震器振子12正常工作，非线性减震器振子12下侧半圆形突起应安装在减震器钢滑道11上侧半圆形凹槽内，硅胶层9粘贴在空腹夹层板屋盖剪力键8侧面(非线性减震器振子一侧)，减震器钢滑道11上表面光滑，但摩擦力不为零，当地震作用时，非线性减震器振子12在减震器钢滑道11上表面左右移动，空腹夹层板屋盖剪力键8限制非线性减震器振子12的振动范围。For the above-mentioned thermal insulation and shock absorbing roof, the reinforced concrete hollow sandwich panel roof structure construction is first carried out, the hollow sandwich panel roof lower rib 10, the hollow sandwich panel roof shear key 8, the hollow sandwich panel roof upper rib 7 and the hollow sandwich panel roof structure layer 6 After the steel bar binding is completed and reliably connected with the column steel bar, the formwork is supported on the outside of the steel bar and a sufficient thickness of the protective layer is ensured, and the concrete is poured as a whole. After the strength reaches the strength of 28 days, each layer of the roof is laid; For the flame retardant straw board insulation layer 4, the upper side of the concrete slope layer 5 should be dried and treated to make it smooth and clean, and then the silicone structural adhesive should be painted on the concrete slope layer 5, and the surface should be dealt with before pasting. The silicone structural adhesive and the straw board insulation layer 4 added with flame retardant are tested for compatibility. The upper side of the straw board insulation layer 4 added with flame retardant should be interface treated to ensure that the straw board insulation layer added with flame retardant is not damaged by external moisture, and the straw board insulation layer added with flame retardant 4 Brush the interface agent on the upper side, and pour the cement mortar leveling layer 3 after drying, and add 30% fire retardant and flame retardant to the straw board insulation layer with flame retardant; at the same time, the shock absorber steel The slideway 11 is fixed on the upper side of the lower rib 10 of the hollow sandwich panel roof by bolts. The bolts should not hinder the normal operation of the vibrator 12 of the upper nonlinear damper. The semicircular protrusion on the lower side of the vibrator 12 of the nonlinear damper should be installed In the semicircular groove on the upper side of the steel slideway 11 of the shock absorber, the silicone layer 9 is pasted on the side of the shear key 8 of the hollow sandwich plate roof (on the vibrator side of the nonlinear shock absorber), and the upper surface of the steel slideway 11 of the shock absorber is smooth , but the friction force is not zero. When the earthquake acts, the nonlinear damper vibrator 12 moves left and right on the upper surface of the damper steel slideway 11, and the hollow sandwich plate roof shear key 8 limits the nonlinear damper vibrator 12. vibration range.

工作过程描述：Description of working process:

上述的保温减震屋盖中空腹夹层板下肋与减震器钢滑道需要螺栓可靠连接。The lower rib of the hollow sandwich panel in the above-mentioned thermal insulation and shock absorption roof needs to be reliably connected by bolts to the steel slideway of the shock absorber.

保温减震屋盖冬季供暖时，由于空腹夹层板屋盖结构层下侧温度较高，钢筋混凝土材料的结构层导热系数较高，导致热量短时间内顺利通过结构层和找坡层，热量到达加入阻燃剂的稻草板保温层下表面，由于稻草板导热系数较小，使得热量在短时间内不会传递至加入阻燃剂的稻草板保温层上表面；反之，夏季由于室外温度较高，外部热量不会经由屋盖大量进入室内。When the thermal insulation and shock absorbing roof is heated in winter, due to the high temperature of the lower side of the roof structure layer of the hollow sandwich panel, the thermal conductivity of the structural layer of the reinforced concrete material is relatively high, resulting in heat passing through the structural layer and the slope layer in a short time, and the heat reaches the input The lower surface of the straw board insulation layer with flame retardant, due to the small thermal conductivity of the straw board, the heat will not be transferred to the upper surface of the straw board insulation layer added with flame retardant in a short time; on the contrary, due to the high outdoor temperature in summer, External heat does not enter the room in large quantities through the roof.

当发生地震作用时，非线性减震器振子在减震器钢滑道限定范围内左右振动，非线性减震器振子在地震来临瞬间俘获地震优势频率，并与地震作用形成类共振，消耗大量地震能量；通过两侧硅胶层及钢滑道还可以消耗部分地震能量，防止整体结构吸收全部输入的地震能量，减小结构地震反应，减轻结构震害。When an earthquake occurs, the vibrator of the nonlinear shock absorber vibrates left and right within the limited range of the steel slideway of the shock absorber. Seismic energy; through the silica gel layer on both sides and the steel slideway, part of the seismic energy can also be consumed to prevent the overall structure from absorbing all the input seismic energy, reduce the structural seismic response, and reduce structural seismic damage.
