As illustrated in figs. 1-16, the above-mentioned working principle for exempting from the energy consumption drag-line support of prestressing force Self-resetting is as follows: sleeve 1 and structure
Main body anchoring, 2 one end of spring are connected with sleeve 1, and the other end is connect with sliding end plate 6, and sliding 6 center of end plate and connecting rod 7 anchor,
Connecting rod 7 is by 2 middle part of spring and passes through the other end and the anchoring of cross connecting piece 8.8 two sides of cross connecting piece connect chain 4, chain
4 are separately connected two runners 3 rotated around the shaft 9 that is connected in sleeve 1, runner 3 by bolt establish friction plate 13 with
Precompression between minor sprocket 1 and minor sprocket 2 12,8 other end of cross connecting piece penetrate strand spiral rope 5, strand spiral rope 5 with
Mild steel connecting plate 19 anchors, and mild steel connecting plate 19 is connected in cross connecting piece 8, and 5 other end of strand spiral rope is pierced by sleeve 1
It is anchored afterwards by cable wire connector 16 and main structure.
It is as shown in figure 16, a kind of that exempt from the course of work that is supported in building structure of prestressing force Self-resetting energy consumption drag-line as follows:
To exempt from prestressing force Self-resetting energy consumption drag-line support 18, diagonally arranged crosswise is in required frame 17, in diagram load F
Under the action of, wherein left side 5 stress of strand spiral rope is stretched, drive the consumption exempted from inside prestressing force Self-resetting energy consumption drag-line support 18
Energy mechanism and resetting-mechanism successively work.
The reset that the present invention makes reseting procedure there is no frictional force obstruction support by the way that rotaring wheel structure is arranged, so existing together
Spring and strand spiral rope, that is, recoverable deformation in regime of elastic deformation realize that support resets；It is connected by setting mild steel
Plate can effectively surrender energy consumption more than under fortification intensity seismic condition, check internal force for support growth, reinforce to main bodys such as beam, columns
The protection of structural elements.
Preferably, spring selects disk spring.
Preferably, mild steel connecting plate selects low-yield mild steel.
Under the conditions of small shake, the pulling force of strand spiral rope passes to big sprocket wheel by chain, and big sprocket wheel has blocked band by pawl
The trend that dynamic minor sprocket one and minor sprocket two rotate, but at this time due to the frictional force between minor sprocket one and minor sprocket two and friction plate
It is larger, it can not overcome, so one end of strand spiral rope and cross connecting piece anchoring is equivalent to fixing end.Under the conditions of this, only
Strand spiral rope plays supporting role.
In-big shake under the conditions of, the frictional force that the pulling force of strand spiral rope overcomes friction plate to provide, therefore strand spiral rope will be drawn
Dynamic cross connecting piece, to pull spring-compressed, at this moment strand spiral rope and spring are series relationship, and the overall stiffness of support is opposite
It is remarkably decreased in the rigidity of strand spiral rope, to inhibit the rapid growth of seismic force, to realize that the protection to main structure is made
With.At the same time, chain-driving big sprocket wheel, big sprocket wheel drives minor sprocket one and minor sprocket two to rotate, with friction plate pivoting friction
Dissipation seismic energy.After earthquake, strand spiral rope pulling force constantly reduces, and spring pulls strand spiral rope to restore deformation, and pawl is not at this time
Big sprocket wheel is blocked again, is hindered from without frictional force, therefore widens sprocket wheel and moves to initial position, until camber of spring is completely extensive
It is multiple, realize runback bit function.
By more than under fortification intensity seismic condition, strand spiral rope pulling force increases up to surrendering mild steel connecting plate,
To check the increase of support pulling force, while also supplement provides energy dissipation capacity, further protects main structure.
