" Humen Bridge pier, tower, anchor GPS construction survey " etc. point out that monitoring system using GPS examines pile composition deformation
It surveys, this method precision is higher, and range is larger, but the interference vulnerable to random signal around.Qian Jiaru is in " building work within 2009
Journey journal " in deliver " Beijing University Gymnasium steel worm-gearing construction simulation and monitoring ", Wang Xiuli in 2012 is at " space structure "
" large span steel structure construction load health monitoring and the sunykatuib analysis " of middle publication, 2012 Nian Lihui are delivered at " civil engineering journal "
" straining health monitoring and calculation simulation analysis during National Aquatics Center Construction of Steel Structure uninstall process and operation " etc. be
Reasonable Arrangement strain transducer monitoring of structures construction loading process and operation stage carry out structural health in wide span steel roof frame
Monitoring, the point layout for later similar projects provide reference；Further there is scholar to propose through acoustic emission device etc.
By monitoring latticed shell structure or the buckling deformation of welded hollow bolted node sphere, but there may be certain difficulty for measurement.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of monitoring and enhancing knot
The multi-functional node locker of structure stability.
The purpose of the present invention can be achieved through the following technical solutions:
Present invention firstly provides the multi-functional node lockers of a kind of monitoring and enhancing structure stability, in two rod pieces
Junction connects the node region to be formed, and adds sleeve, sensor and mating supporting member,
The sleeve both ends are latched on two rod pieces of plane node two sides with supporting member, to realize rod piece and set
The common stress of cylinder, the rod piece pass through the overhang bracket element of sleeve, and the connection between the supporting member and the rod piece is
Sliding contact connection, allows the overhang bracket element of sleeve to slide axially along the rod piece,
Sensor is equipped in the sleeve, the sensor is located at below node, when unstability takes place in structure, causes
Column joints deformation increases rapidly, and after deforming more than a certain range, node and sensor contacts are issued warning signal；Meanwhile node with
Internal Force Redistribution occurs for sleeve entirety stress, to achieve the purpose that prevent or delay structural instability.
Further, the supporting member uses positioning bolt, is fixed sleeve and rod piece by positioning bolt, described fixed
Position bolt passes through the screw hole on sleeve, connects between smooth bolt end and rod piece for sliding contact, and the positioning bolt is permitted
Perhaps the axially opposing displacement of rod piece occurs for rod piece and sleeve, but limits rod piece and lateral displacement occurs, to realize that rod piece and sleeve are total
Same stress.
Further, the mating supporting member passes through the limit using position-arresting disk, baffle and connection bolt, the rod piece
Position disk, the baffle and sleeve ends medial surface weld, and the position-arresting disk is fixed with the baffle by connecting bolt；The limit
Connection between position disk and the rod piece is sliding contact connection, and the position-arresting disk allows rod piece that rod piece axial direction phase occurs with sleeve
It to displacement, but limits rod piece and lateral displacement occurs, to realize rod piece and the common stress of sleeve.
Further, the sleeve is using hollow sections components such as elliptical tube, round tube, rectangular tube or rectangular tubes.
Further, the sleeve uses assembled, latticed members, and the sleeve is led to by the identical channel steel in two sections of sections
It crosses otic placode or angle steel to fix with bolt is connect, wherein be welded to connect between the otic placode and channel steel, form weld seam, the angle steel
It is connect between channel steel by positioning bolt.
Further, there are two the sleeve is set, one separate ferrule is respectively set in node two sides, two rod pieces are each passed through
One sleeve is connected to form overall coordination stress with structural steel connecting member between two sleeves.
Popularization of the multi-functional node locker based on the monitoring and enhancing structure stability to three-dimensional space node
Using the present invention also provides the multi-functional node lockers of another monitoring and enhancing structure stability, converge in plurality of rods part
Commissure connects the space nodes region to be formed, and adds cover plate, sensor and mating supporting member, cover plate periphery supporting member
It latches on all rod pieces on space nodes periphery, to realize rod piece and the common stress of cover plate, the rod piece passes through cover plate
Periphery supporting element, the connection between the supporting member and the rod piece is sliding contact connection, allows the periphery branch of cover plate

Position disk (6) and cover plate (3b) sidewall paneling are fixed by connection bolt (8)；Company between the position-arresting disk (6) and the rod piece (2)
It is connected in sliding contact connection, the position-arresting disk (6) allows rod piece (2) and cover plate (3b) that rod piece (2) axially opposing displacement occurs, but
It limits rod piece (2) and lateral displacement occurs, thus realize rod piece (2) and cover plate (3b) common stress,
Cover plate (3b) sidewall paneling and bottom plate can appropriate aperture both convenient for directly observation rod piece and column joints deformation also facilitate peace
Dress, maintenance, maintenance.
9. according to claim 1 or 7 it is described it is a kind of monitoring and enhancing structure stability multi-functional node lockers, feature
It is, good ductility, metal material of good toughness or alloy material, example can be used in the rod piece (2), sleeve (3) or cover plate (3b)
Such as building structure steel or aluminum alloy materials, it is good that intensity height, good toughness, the transparency also can be used in sleeve (3) or cover plate (3b)
Material.
10. according to claim 1 or a kind of 7 multi-functional node lockers of monitoring and enhancing structure stability, special
Sign is, gag lever post (12) is arranged at the node (1), more efficiently to limit column joints deformation, timely trigger sensor
Pre-warning signal.
