Description
Technical field
The utility model is relevant for a kind of support termination actuator devices, and particularly relevant for a kind of support termination actuator devices of self adaptation support system.
Background technology
Be accompanied by the great development of urban construction, excavation of foundation pit has been tending towards extensiveization and the big degree of depthization, and the construction environment complexity, and how based on the suitable practice of open cut, foundation pit construction requires more and more harsher to Deformation Control.The self adaptation support system is to combine new and high technology means such as modern mechanical-electrical-hydraulic integration automatic control technology, Computerized Information Processing Tech and visual control system, axial force of the supports is carried out round-the-clock uninterrupted monitoring, and according to parameter value that high-precision sensor is surveyed axial force of the supports is carried out in good time automatic or manual and compensate the support system that reaches control foundation pit deformation purpose, can solve foundation pit construction the harshness of distortion is required problem.
The form of structure that steel supports is of a great variety, depends on that residing geology of foundation ditch and ambient conditions, planar dimension, the degree of depth etc. are all multifactor, and the single span pressure lever type supports in common having, the multispan pressure lever type supports and the two-way multispan pressure lever type of opposite supporting type supports three kinds.The self adaptation support system mainly supports corresponding to the single span pressure lever type.
In the common engineering, after steel supported and to apply prestressing force and hold out against, end welding was fixing, and the other end is installed active head with the locking of gad piece.After this kind steel support structure had applied prestressing force, prestressing termination node was welded, and can't repeat repeatedly it to be carried out the prestressing force adjustment.In the actual engineering, because external environment and steel support and steel is carved unfavorable factors such as relaxing of piece, the axle power that steel supports is constantly loss, for the distortion that guarantees foundation ditch meets the demands, need constantly the steel axial force of the supports to be compensated, traditional braced structures can't meet the demands.
In addition, traditional termination node that steel supports normally directly is shelved on the bracket, simple structure, but installation process is easily eccentric, thus produce additional shear stress and moment of flexure, may cause steel to support unstability.
The steel of Shanghai company development supports and is added with prestressing apparatus, the outside of forming the engaging body case two mutual sockets of steel case is fixed with jack, the two ends of jack are separately fixed on two steel casees, the corresponding rectangle that has is carved the hole on two steel case upper and lower faces behind the fit, be inserted with steel in the hole and carve pin, this device can be regulated prestressing force as required, has reached control bracing of foundation pit body deformability effect.
Though this device has been realized repeatedly adjusting steel and has been supported prestressing force, has the following disadvantages:
1 this device is arranged in steel and supports the middle part, easily reduces the resistance to overturning of structure;
2 these devices are applicable to little tonnage jack, are difficult to fix for the large-tonnage oil cylinder;
3 these device degrees of regulation are lower, rely on steel to carve piece and are difficult to fixedly guarantee that axle power is stable.
Be accompanied by the great development of urban construction, excavation of foundation pit presents the characteristics that scale is big, the degree of depth is big, and the surrounding enviroment complexity, and the performance that steel is supported has proposed harsh requirement, and traditional termination node apparatus can't adapt to this requirement.
