Cylinder and multiple reinforcements of second flange disk, so far, complete the whole of this axle power regulation elastic device being used on bracing members
Individual manufacturing process.
A kind of bracing members mounting structure, refers to Fig. 2, including bracing members body 1, and one end of bracing members body is fixing end
1-1, the other end of bracing members body is flexible joint end 1-2, and purlin 2 is enclosed in the two ends of bracing members body by steel, and top pressure is in place
In the ground-connecting-wall 3 of both sides, on upper or fender post, specifically, correspondence steel is located on the ground-connecting-wall of both sides or on fender post and encloses purlin
Lower section be bolted bearing 4, steel encloses purlin and is supported on bearing, the inner side for enclosing purlin in steel be provided with for
The bracing members seat 5 of support bracing members body corresponding end.Above-mentioned axle power regulation elastic device is serially connected with bracing members body, or
The fixing end of bracing members body is using above-mentioned axle power regulation elastic device.Specifically, when this axle power regulation elastic device string
When being connected on bracing members body, the end positions for connecting axle power regulation elastic device in bracing members body are welded with flange
Disk, two ring flange is attached respectively with the ring flange at axle power regulation elastic device two ends by bolt；And work as this axle power
When regulation elastic device is used as the fixing end of bracing members body, the ring flange of axle power regulation elastic device one end is only needed
It is bolted with the ring flange for being welded on bracing members body corresponding end.
By taking the subway work project of certain extremely frigid zones as an example, enumerate using existing bracing members and using this axle power of increase
Difference of the steel support structure of regulation elastic device to Foundation.
The subway work area category extremely frigid zones, annual range of temperature Δ T is at 70 degree or so.Substantially calculate：Foundation ditch width L is pressed
20m is calculated, and the thermalexpansioncoefficientα of steel is 1.2 × 10-5/ DEG C, if bracing members are installed when summer is most hot, to winter most
The length of bracing members can shorten 16.8mm (Δ L=L × Δ T × α=20 × 1000 × 70 × 1.2 × 10 when cold-5=
16.8).The ground-connecting-wall or fender post for assuming bracing members two ends is not moved or indeformable, then the axle power of bracing members would be possible to disappear
Lose, the stability of foundation pit enclosure structure will be threatened seriously, and the bracing members in free state are also in itself one very big
Danger；Conversely, fender post will be damaged because axle power is excessive or cause bracing members to produce plastic deformation.
During temperature change, why the axle power of bracing members can drastically change, and be because that its length has the trend for changing.
Once using this axle power regulation elastic device, when bracing members have elongation trend, stage clip will be compressed, and have contracting in bracing members
Stage clip also can extend during short trend, what the change of axle power necessarily still had, but can be much smaller.Above it was computed, 20
The long bracing members year maximal dilation amount of rice only 16.8mm, the impulse stroke of stage clip is also just without exceeding this length.Present
Requirement is to produce a kind of stage clip, and when axial pre-applied force (such as 30 tons) reaches requirement, it is in the centre position of work,
Compressed or extended still ensure that elastic force reaches that the axle power of bracing members requires after 10mm just can be with.If the working line of stage clip
Journey is fabricated to ± 8mm rather than ± 10mm, and the short meeting of stroke causes total more stable.For by law of elasticity, such as stage clip
Impulse stroke L can reach 50mm under 30 tons of pressure F, often increase and decrease length Δ L=8mm, and changes delta F of power is 4.8 tons of (Δ F
=F/L × Δ L=30/50 × 8=4.8), axial force not rapid fluctuation is can ensure that substantially.Can compare accordingly, temperature change
Once, be not added with stage clip bracing members axle power increase and decrease 4.6 tons, and add compression spring bracing members length change be：Δ L=L × α × Δ
T=20 × 1000 × 1.2 × 10-5× 1=0.24mm, then the change of power is turned to：Δ F=F/L × Δ L=30/50 × 0.24=
0.144 ton.Take on a new look or no small, the change of power almost reduces many times of 30 (4.6/0.144=31.94).Therefore it is theoretical
On be feasible.
