Exhibition.
According to a kind of pre-buried type bottom offset silk device described in the utility model, compared with existing displacement bar, have with
Lower feature：
(1) material cost is saved, pre-buried displacement bar test needs to arrange that interior reinforcing bar or steel pipe, displacement pillar are also steel pipe,
Wherein displacement bar and displacement pillar specification need to meet some strength requirement, and reinforcing bar and the conjunction of steel pipe off-gauge will produce when requiring and disturb
Song deformation, therefore the displacement silk device of the remote over dimensioning specification very little of material cost；
(2) installation is simple and fast, and pre-buried type bottom offset silk device only needs a little to be welded on load box lower connecting plate, then will be whole
Root include displacement silk displacement casing stretch with main reinforcement banding fixed, and displacement bar needs will often save displacement bar and pierce into displacement
It places often to save in steel reinforcement cage after pillar and fix, the abutting joint for carrying out often saving displacement bar is needed when then steel reinforcement cage docks, then
Displacement pillar is docked again, and working hour is long, complicated for operation；
(3) success rate is high, and pre-buried type bottom offset silk device has multi-layer sealed compressive property, can effectively ensure that displacement silk
Normal operation, and the welding of displacement bar installation is limited by field condition, and the sealing welding quality of displacement pillar is difficult to control, behaviour
The case where work is susceptible to the leakage phenomenons such as solder skip, slag inclusion accidentally, and displacement bar is caused to be closed, and experiment can not be carried out effectively；
(4) displacement is transmitted accurate and reliable, and pre-buried type displacement silk is single steel wire, and performance is good, light-weight, pliability is high can be with
It stretches and does not generate secondary deformation, and is small with the lubrication pipe friction in displacement casing, displacement transmission is accurate sensitive, and displacement bar is conducted oneself with dignity
Greatly, in displacement pillar there are flexural deformation, there is disturbance in when operation, and frictional force is big, and it is unreliable that displacement transmission is easily distorted.
The above, the only preferred embodiment of utility model, are not intended to limit the protection domain of utility model,
It is all within the spirit and principle of utility model made by all any modification, equivalent and improvement etc., should be included in practical new
Within the protection domain of type.
