Description
Technical field
The utility model belongs to the realm of building construction, is related to Flexible Node and two-way steel applied to two-way steel support structure
Supporting construction.
Background technology
At present in construction, excavation of foundation pit typically using armored concrete as the horizontal support in hole, it is but this
Way construction cost is high, it is impossible to reuse, and workload is particularly removed after the completion of construction greatly, noise is big, seriously polluted, no
Beneficial to environmental protection.And another method is exactly that, as the horizontal support after underground excavation, it overcomes concrete with bracing members at present
The shortcoming of horizontal support, with reusable, the advantages of beneficial to environmental protection.
It is by being formed to applying prestressed method in end by root bracing members when Large Foundation Pit uses two-way bracing members
Support system, it vertically and horizontally supports intersection typically to use flange joint or anchor ear node, and this support node saves for rigidity
Point.
Those skilled in the art often ignore and applicant have observed that be：Two-way steel support structure is applying prestressing force
When, there is the axial deformation for applying prestressed sequencing and support, apply prestressed support generation and be compressed axially change
Shape.Due to the presence of rigid joint, this axial crushing deformation can be directly passed to by rigid joint it is vertical to support, hang down
It is straight to support will bend, bending it is vertical to support pair prestressed will necessarily support neighbouring in the same direction with applying
Bracing members produce node additional bending moment, can so be stepped up the stress of bracing members.Therefore, after construction to some supports,
The bracing members stress of previous construction stress is stepped up, and can be caused the overstressing of support system and be failed.
As shown in figure 1, installing jack at the digital position shown in lower Fig. 1, and apply prestressing force one by one by numerical order
(such as 756 tons), i.e., first apply No. 1 support prestressing force, then applies No. 2 support prestressing force, then gradually applies to No. 12 supports
Prestressing force, during applying stress according to sequence number, applies stress value and gradually increases, result of calculation shows, the 1st loading
When maximum stress value be -160.5MPa, and it is last apply No. 12 support prestressing force when, stress value reach maximum -
391.8Mpa。
Above-mentioned result of calculation shows, because the two-way steel support structure using rigid joint is applying prestressing force by root
When, the bracing members for causing construction in later period are produced to the effect of additional bending moment to having applied prestressed bracing members, respective support
Stress maximum increases to 391.8MPa by 160.5MPa, when the tolerance range more than steel support structure, it is possible to cause branch
The overstressing of support body system and fail.

Simultaneously as the longer generally 25m to 50m of steel pipe, if by-level is to no support meeting unstability, this practicality is new
The Flexible Node of type also causes the bracing members of two vertical direction to have effect (using flexible member) constrained each other, makes bracing members water
Flat not unstability, by calculating, about 7.5 tons of unstability support force, so only suitable flexible member need to be selected to prevent bracing members
Unstability.
The Flexible Node applied to two-way steel support structure that the utility model is provided, makes horizontal support and vertical support not
Directly contact, when loading axle power to horizontal support, the compression that horizontal support is produced will not be directly acted on and internal box
The vertical support of connection so that the lateral displacement of vertical support is greatly reduced, thus effectively reduces horizontal support axle power and adds
The additional bending moment produced during load to vertical support, improves the force-bearing situation of whole two-way steel support structure.
Foregoing description is only the description to the utility model preferred embodiment, not to any limit of the utility model scope
Calmly, the those of ordinary skill in the utility model field does according to the disclosure above content any change, modification, belonging to right will
Seek the protection domain of book.
