Description
Technical Field
The utility model relates to the technical field of shockproof and damping structure equipment, in particular to a shock insulation building tensile device and an adjustable connecting piece used by the shock insulation building tensile device.
Background
The building shock insulation refers to a technology for arranging a shock insulation layer in a building structure to greatly reduce the earthquake action of an input structure and reduce the earthquake reaction of the structure, and effectively protect the life and property safety of the building structure and people in the building. In the application development process of the technology, the shock insulation support is the most common shock insulation device used in the shock insulation layer of the current shock insulation building due to the excellent capability of absorbing and dissipating the seismic energy, but the common shock insulation support can only bear vertical pressure and horizontal shearing force to a certain extent, the tensile capability is extremely limited, the tensile capability requirement of the shock insulation support of the current building shock insulation rubber support JGT118-2018 is that the vertical ultimate tensile stress is not smaller than 1.5MPa, and correspondingly, related technical standards and specifications require that the shock insulation support is required to be controlled not to generate tensile stress under the action of the earthquake or to be controlled within 1MPa when the shock insulation structure is designed so as to ensure that the shock insulation support is not damaged, and the upper structure height-width ratio is usually limited to be not larger than 4. However, in practical engineering projects, the tensile stress of high-rise, super-high-rise and partial high-aspect-ratio shock insulation buildings in high-intensity fortification areas is a common phenomenon, and the size is difficult to control.
Therefore, the development of the high-performance tensile device for controlling the overturning moment and the tension of the shock insulation layer and avoiding the overturning collapse of the shock insulation building has great practical significance. At present, part of production, study, research and development mechanisms and scholars are developing the tensile device, and tensile products are continuously put into engineering application, but the problems of complex structure, high production cost, high installation precision, unstable tensile effect, easy failure of the device and the like are outstanding, and the application and popularization of the tensile device are greatly restricted.
The main body typical structure of the current mainstream tensile device is composed of an upper slide rail, a lower slide rail and a drawknot module, wherein the upper slide rail, the lower slide rail and the drawknot module are respectively connected with the upper structure and the lower structure of a shock insulation layer and are mutually perpendicular, the drawknot module is usually integrally processed and formed, tension is transmitted through a mode that a clamping groove which is processed in advance on the module is tightly meshed with the upper slide rail and the lower slide rail, but the defect of the type of tensile device is obvious, because the tensile device only considers tension transmission under the tension and tension shearing working conditions, the problem that the tensile device is stressed due to complex factors such as deformation of the lower structure, foundation settlement, compression deformation of a shock insulation support and the like often exists in practical engineering, once the tensile device is stressed, the tensile effect of the tensile device is inevitably greatly reduced or even disabled, and the expected tensile capacity cannot be exerted even the shear deformation of the shock insulation support is influenced under the earthquake action, so that the structural safety is influenced.
Another common type of tie module is composed of an upper part and a lower part which are mutually engaged and formed by combining two or more parts, and the upper part and the lower part are respectively tightly engaged with an upper sliding rail and a lower sliding rail through prefabricated clamping grooves to transfer tension. In order to avoid the failure of the tensile device due to compression, a certain gap is reserved at the inner engagement part of the tensile device when a drawknot module is designed by some manufacturers. The problems existing at present are as follows: (1) Because the width of the reserved gap is difficult to determine, a certain determined value can be selected according to experience and actual conditions and cannot be adjusted, if the gap reservation is too small, the possibility that the tensile effect is influenced even fails due to the fact that the tensile device is pressed in the later use process is still caused, if the reserved gap is too large, the tensile device is not stressed and does not play a role in tension due to the fact that the gap of the engagement part is too large under the earthquake action is possibly caused, and therefore the tension exceeding limit value of the support of the vibration isolation layer is pulled out, and hidden danger is caused to the safe burying of the vibration isolation building structure. And (2) the requirement on the installation precision is high, and the installation difficulty is high. Because the tensile device of this type is highly fixed, in order to guarantee the tensile effect, only the construction mode of installing the upper connecting piece and the tensile device main body first, then installing the lower connecting piece and then pouring the lower buttress (column) can be adopted. If the upper and lower connecting pieces are constructed first, then the tensile device main body is installed later, and the tensile device main body is possibly not installed or is not firmly connected due to the fact that the installation height is not adapted.
