detailed description of the invention
For describing the technical solution of the utility model in detail, provide specific embodiment below in conjunction with accompanying drawing.
Core concept of the present utility model is, in support installation process, make support first jointly bear vertical load and wind load etc. with main structure laterally to act on, guarantee the structural safety of construction stage, when being supported on the internal force of construction stage generation after installation by specific device release, avoid supporting and because larger load can be born, operational phase may be caused under wind load or geological process, support to be surrendered too early, affect wind resistance and the anti-seismic performance of structure.
Under the guide of above-mentioned core concept, by the following device realization that can discharge erection stage internal force to bracing members.Describedly can comprise node junction plate, support and connection plate to the device that bracing members discharges erection stage internal force, vertical load release of internal force mechanism and back shaft are to deformation mechanism, and node junction plate is for being connected with the gusset plate in main structure; Support and connection plate is connected with supporting base end portion; Described node junction plate and described support and connection plate are connected into entirety by release of internal force mechanism, and are discharged the load being supported on erection stage and bearing by self-regulation; To deformation mechanism, it is axially arranged along described support and connection plate back shaft, and release supports axial deformation during release internal force.
The specific embodiment of technique scheme is see Fig. 4 and Fig. 5, and wherein, Fig. 4 is the sectional view after the device that can discharge erection stage internal force to bracing members has been assembled; Fig. 5 is the device exploded view that can discharge erection stage internal force to bracing members.A kind of device to bracing members release erection stage internal force comprises the node junction plate 1 of pair of parallel setting, 3, be arranged on node junction plate 1, support and connection plate 2 between 3, bolt 4 and butterfly spring 8, support and connection plate 2 offers the slotted hole 201 realizing release back shaft internal force, the screw rod of bolt 4 is successively through node junction plate 1, support and connection plate 2, node junction plate 3, and slotted hole 201 position of self-supporting junction plate 2 is passed, screw rod section between node junction plate 1 and nut overlaps and has butterfly spring 8, disc spring backing plate 9 is had between butterfly spring 8 and node junction plate 1, disc spring backing plate 7 is arranged at butterfly spring 8 top, bolt backing plate 5 is lined with between loaded plate 6 and nut, packing ring 10 and bolt backing plate 11 is lined with between node junction plate 3 and bolt 4 termination.
Said structure is a concrete embodiment, and when other are implemented, the other types spring that butterfly spring 8 can have certain deflection by other replaces.
In other embodiments, the setting position of butterfly spring 8 can be arranged by the screw rod section between node junction plate 3 and bolt 4 termination or between node junction plate 1 and nut simultaneously.
The concrete steps adopting the above-mentioned device that can discharge erection stage internal force to bracing members specifically to carry out when high-rise steel structure supports are as follows:
Step one, the device that bracing members discharges erection stage internal force can be fixedly connected with support and main structure, to realize supporting or basic synchronization synchronous with agent structure and construct, the structure stress of support participation erection stage; Structure after bracing members is connected with agent structure, see Fig. 6, is with the difference that prior art is maximum, adopts the device A that can discharge erection stage internal force to bracing members to realize support 13 and be connected with agent structure (steel column 12 and girder steel 14) in this node.The device that bracing members discharges erection stage internal force can be fixedly connected with support and main structure, installation process is particularly: constantly tightened by the nut of bolt 4 and butterfly spring 8 is compressed, butterfly spring after compression 8 pairs of node junction plates 1 and node junction plate 3 produce precompression, prestressed size can be designed by the rigidity of stroke stubborn in nut and butterfly spring 8, and then between node junction plate 1 and support and connection plate 2, and produce frictional force between support and connection plate 2 and node junction plate 3, this frictional force can resist the internal force that the construction stage produces in support, ensure that the safety of structure in work progress.
Step 2, the agent structure installation of a construction stage (floor or a construction flowing water section), according to the result of work progress checking computations and the bearing capacity of this device, determine the timing node discharging internal force for support.
Step 3, release internal force for support, first looser a bolt, the frictional force between node junction plate and support and connection plate reduces gradually, and screw rod can move release along slotted hole and support axial deformation, and support unloading, eliminates this construction stage internal force for support.In internal force for support dispose procedure, owing to being provided with butterfly spring, the precompression that junction plate contact surface produces reduces gradually, and support unloading process is steady, safety.
Step 4, after support unloading completes, the nut tighted a bolt immediately, makes the compressive strain of butterfly spring return to original state, supports and again participates in work, for structure provides anti-side rigidity.
Step 5, after whole support unloading is completed, support and connection plate to be welded with node junction plate part in agent structure installation, then release of internal force mechanism is removed, finally will remain support and connection plate and weld with node junction plate, support final installation.
The embodiment that above-described embodiment content just adopts for the ease of understanding the technical solution of the utility model, is not intended to limit the utility model.Technician in any the utility model art; under the prerequisite not departing from the core technology scheme that the utility model discloses; any amendment and change can be made in the form implemented and details; but the protection domain that the utility model limits, the scope that still must limit with appending claims is as the criterion.
