Abstract

Originally it is new to disclose a kind of two benches tension stopping means, including the upper bracket and undersetting that are oppositely arranged, the spacing electric fuse of first stage tension and second stage tension limit component are provided between upper bracket and undersetting, the length of the spacing electric fuse of first stage tension be equal on the inside of upper bracket and undersetting between spacing, the length of run of second stage tension limit component be more than on the inside of upper bracket and undersetting between spacing.A kind of this new two benches tension stopping means, accurate auxiliary realize the requirement of " three levels are set up defences, two-stage design ".Make dynamic respond of the structure under wind load and little shake effect less, do not affect normal operating condition;Can consume energy in safe displacement response range under big shake effect so as to reduce the seismic response of structure;With less volume and easy construction, manufacture is promoted the use of conveniently;Install convenient, changes after convenient damage.

Description

A kind of two benches tension stopping means
Technical field
Originally it is new to be related to brick or concrete duct field, specifically a kind of two benches tension stopping means.
Background technology
China is existing《Earthquake resistant code》Using " three levels are set up defences, two-stage design " method.Structure needs little in design Shake and the two-stage design of big shake, or have satisfaction to generally use the different demands of state and limit state, existing shock insulation subtracts Device is more difficult accurately realizes this target for shake, it is therefore desirable to which a certain attachment device is aiding in accurate realizing that " three levels are set up defences, two ranks Section design ".
The content of the invention
Goal of the invention:In order to overcome the deficiencies in the prior art, a kind of spacing dress of two benches tension of the new offer of sheet Put, under little shake, wind load effect and big shake effect, auxiliary limits the deformation of existing shock insulation damping device respectively, preferably realizes The two stage design requirement of three levels of providing fortification against earthquakes, and device is easily changed after damage, it is easy to the quick reparation after shake.
Technical scheme:To solve above-mentioned technical problem, a kind of this new two benches tension stopping means is set including relative The upper bracket put and undersetting, are provided with the spacing electric fuse of first stage tension between upper bracket and undersetting and second stage is received Spacing between drawing limit component, the length of the spacing electric fuse of first stage tension to be equal on the inside of upper bracket and undersetting, second-order The length of run of Duan Shoula limit components be more than on the inside of upper bracket and undersetting between spacing.
Wherein, the spacing electric fuse of first stage tension is the straight rod iron of cutting.
Wherein, second stage tension limit component is a spiral rod iron, and the length varying value which launches is placement location phase Design maximum value to displacement.
Wherein, the spacing electric fuse two ends of first stage tension are respectively and fixedly connected with upper with second stage tension limit component two ends On the inside of bearing and undersetting
Beneficial effect:A kind of this new two benches tension stopping means, has the advantages that:
1st, accurate auxiliary realizes the requirement of " three levels are set up defences, two-stage design ".Structure is made to act in wind load and little shake Under dynamic respond it is less, do not affect normal operating condition;Big shake effect under can consume energy in safe displacement response range from And reduce the seismic response of structure;
2nd, with less volume and easy construction, manufacture is promoted the use of conveniently;
3rd, install convenient, changes after convenient damage.
Description of the drawings
Fig. 1 is a kind of this new dimensional structure diagram of two benches tension stopping means;
Fractionation organigrams of the Fig. 2 for Fig. 1 shown devices;
Fig. 3 is Fig. 2 shown device limit state schematic diagrams;
In figure:1- upper brackets, 2- undersettings, 3- first stage spacing electric fuse, 4- second stage tension limit components.
Specific embodiment
It is further described to originally new below in conjunction with the accompanying drawings.
A kind of two benches tension stopping means as shown in Figure 1 to Figure 3, including upper bracket 1, and phase identical with upper bracket 1 To the undersetting 2 for arranging, the spacing electric fuse 3 of first stage tension and second stage are provided between upper bracket 1 and undersetting 2 Tension limit component 4.Upper bracket 1 and 2 profile of undersetting in step-like, wherein upper bracket 1 and undersetting 2 and first stage tension Spacing electric fuse 3 is connected side for inner side with second stage tension limit component 4, contacts one outside upper bracket 1 and undersetting 2 Side is outside, and inner side projected area is less than outside, convenient this new stopping means prepared screw-bolt hole road or as draw-in groove with it is outer Portion connects.Wherein, the spacing electric fuse 3 of first stage tension is the straight rod iron of the less cutting of a diameter, and first stage tension is spacing The length of electric fuse 3 be equal on the inside of upper bracket 1 and undersetting 3 between spacing, and its length adds bearing 1 and undersetting 2 Spacing of the thickness for lower new stopping means institute placement location of resting state, meets disconnected when pulling force exceedes a certain design load Split.Second stage tension limit component 4 is a helical form rod iron, and during its expansion, the changing value of length is this Novel stop block institute The design maximum value of placement location relative displacement, and meet will not rupture in the design maximum value of relative displacement.First stage The spacing electric fuse 3 of tension is respectively welded in the inner side of upper bracket 1 and undersetting 2 with the two ends of second stage tension limit component 4, Upper bracket 1 is fixed in isolation cushion using bolt by reserving hole channel respectively with undersetting 2 and is vertically connected with plate.
When little shake or the lower restriction isolation cushion of wind load effect do not produce or only produce minimum deformation, when big shake is acted on first The spacing electric fuse of stage tension 3 ruptures, and isolation cushion deforms under the protection of second stage tension limit component 4 in allowed band So as to reach optimal isolating affection.As shown in figure 3, after 3 design load of electric fuse spacing more than first stage tension, electric fuse 3 fractures, under the extreme displacement state for reaching second stage design, second stage tension limit component 4 is to stretch limit state. When external action terminates, after this new damage, new equipment is changed in the original location.
The above is only this new preferred implementation, it should be pointed out that:For the ordinary skill people of the art For member, on the premise of without departing from this new principle, some improvements and modifications can also be made, these improvements and modifications also should It is considered as this new protection domain.
