The utility model discloses the stress of initial inefficacy member can be simulated accurately to the device, and degree of automation is high, repeatedly usable, and it is poor to have solved the initial destruction introducing device repeatability of present collapse experiment, and the scheduling problem is hanged down to the degree of becoming more meticulous.
Description
Technical field
The utility model relates to structural collapse experimental study field, space in construction work, in particular, relates to a kind of space structure collapse experiment absorption type electromagnet initial destroy device.
Background technology
In large-span space structure collapse experiment, by the inner a certain rod member of initial destroy introducing device model configuration because the process that accidentalia occurs to destroy is the gordian technique that Progressive Collapse is tested.For reinforced concrete frame structure, carry out " removal " concrete frame trestle by explosive manner, but the method be not suitable for small scale model and metal construction; For large-span space structure, in the middle of test in the past, usually adopt the mode that manually sawed-off, steel clamp and wedge shape steel toe are connected to introduce primary failure component, these operations often need manually to go to participate in destroying, wasting manpower and material resources, and can not warranty test precision and security, in order to the stress of primary failure component and surrounding rod member can be simulated more accurately, a set of initial destroy device being applicable to large-span space structure collapse experiment need be researched and developed, make it have the reliability of height, security and repeatability.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, a kind of space structure collapse experiment absorption type electromagnet initial destroy device is provided, this device accurately can simulate the stress of primary failure component, automaticity is high, reusable, solve existing collapse experiment initial destroy introducing device repeatable poor, become more meticulous the problems such as degree is low.
The purpose of this utility model is achieved through the following technical solutions:
Space structure collapse experiment absorption type electromagnet initial destroy device, comprise two nodes to be destroyed being subject to tension, described node to be destroyed is respectively by the screw rod that has been threaded, one end that described screw rod is connected with node to be destroyed is internal thread, and other one end of screw rod is external thread and has been threaded connection absorption type electromagnet.
The internal thread length of one of them screw rod described is the twice of another screw rod internal thread length.
The internal thread of described two screw rods is plus thread.
Described absorption type electromagnet is provided with threaded hole.
The specification of described external thread of screw is M8-6g.
Compared with prior art, the beneficial effect that the technical solution of the utility model is brought is:
1. the utility model device on node to be destroyed respectively by the screw rod that has been threaded, one end that screw rod is connected with node to be destroyed is internal thread, other one end of screw rod is external thread and has been threaded connection absorption type electromagnet, and after unexpected power-off, electromagnet magnetic force disappears, device disconnects, can realize rod member inefficacy between two nodes to be destroyed and reach the simulation of demolition purpose, this plant automation degree is high as seen, simple structure, without the need to manual operation, safe and reliable.
2. the utility model device is connected with each node by screw thread, therefore easy accessibility, reusable, also can organize more and use together, the dynamic failure process simultaneously lost efficacy with rod member between accurate analog many group nodes, is applicable to large-span space structure model collapse experiment.
3. two screw rod internal thread length of the utility model device differ, and adjustable extent is large, applied widely.

Fig. 2 is component schematic diagram to be destroyed.
Fig. 3 is the component schematic diagram after introducing the utility model device.
Reference numeral: 1-screw rod 2-screw rod 3-internal thread 4-internal thread 5-absorption type electromagnet 6-node 7-to be destroyed connecting link
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described:
As shown in Figure 1 to Figure 3, space structure collapse experiment absorption type electromagnet initial destroy device, comprise two nodes 6 to be destroyed being subject to tension, node 6 to be destroyed is respectively by screw rod 1 and the screw rod 2 of being threaded, one end that screw rod 1 is connected with node 6 to be destroyed with screw rod 2 is respectively internal thread 3 and internal thread 4, other one end of screw rod 1 and screw rod 2 is external thread, and externally threaded specification is M8-6g.The male end of screw rod 1 and screw rod 2 has all been threaded connection absorption type electromagnet 5, and absorption type electromagnet 5 is provided with threaded hole.
Wherein the length of internal thread 4 is twices of internal thread 3 length, and they are plus thread.
Concrete using method of the present utility model is as follows:
Under original state, node 6 to be destroyed is connected by connecting link 7, is in tension state, now the utility model device will be substituted connecting link 7 to carry out the simulation of initial destroy; Because the screw thread of internal thread 3 and internal thread 4 is plus thread, when the precession of right-hand member screw thread, left end screw thread screws out, and the utility model device and node to be destroyed 6 still can freely be dismantled after assembling; After assembling, ensure that the utility model device entire length is identical with connecting link 7 length, with warranty test accuracy, while threaded portion be the most weak location of screw rod 1, screw rod 2 and connecting link 7, should ensure that this place is equal with the intensity of other rod members of model.In process of the test, absorption type electromagnet 5 is as the primary failure component of the utility model device, and after unexpected power-off, electromagnet magnetic force disappears, and device disconnects, and can realize the simulation that in large-span space structure collapse experiment, rod member lost efficacy.
For absorption type electromagnet 5, should ensure that the minimum suction after being energized between absorption type electromagnet 5 is greater than the tension of connecting link 7, the utility model device can not destroy in advance before triggering.
