Description
Technical field
The utility model belongs to Steel Structural Design construction applications, and in particular to a kind of company of steel strand prestress flexible draw bar
Binding structure.
Background technique
Steel structure support or brace mostly use steel pipe or fashioned iron at present, in order to reduce steel using amount, can be used flexible draw bar into
Row substitution, but the flexible draw bar of round steel more difficult, the low bearing capacity that accurately applies pretension;Parallel wire unit and half parallel steel wire
The Cable Structures cost such as beam is high, is unfavorable for the popularization of prestressing force flexible draw bar.In order to reduce prestressed draw-bar cost, Saving steel
Amount, and pretension relatively accurately is applied to flexible draw bar, it can be using steel strand wires substitution parallel wire unit and half parallel steel
Steel strand wires are connected on the main elements such as steel column by tow by special connection structure, are formed steel strand prestress flexibility and are drawn
Bar.
Utility model content
The purpose of this utility model is to provide a kind of connection structures of steel strand prestress flexible draw bar, twist using by steel
Line is connected on the connecting plate welded with steel column by pressure connection terminal, and the accurate adjusting yoke length of flower basket bolt is arranged to apply steel
Twisted wire pretension forms prestressing force flexible draw bar.
To realize the above-mentioned technical purpose, the utility model adopts the following technical solution:
A kind of steel strand prestress flexible draw bar connection structure, including U-shaped connecting plate, flower basket bolt and pressure connection terminal, wherein
The bottom surface of the U-shaped connecting plate is equipped with through-hole, and both ends are welded on steel column;One end of steel strand wires passes through U-shaped connecting plate bottom surface
Run through flower basket bolt after through-hole, the steel strand wires end being pierced by from flower basket bolt other end is fixed by pressure connection terminal;The flower basket bolt
Adjustable in length, when adjust flower basket bolt extend flower basket bolt when, to steel strand wires apply pretension.
Preferably, the flower basket bolt is made of the outer sleeve being threadedly engaged and two inner sleeves, wherein flower basket bolt
Outer sleeve inside have screw thread, and have screw thread outside the inner sleeve of flower basket bolt, and the screw thread of two inner sleeves is on the contrary, work as the gaily decorated basket
Its two internal flower basket bolt inner sleeve moves in the opposite direction when the outer sleeve rotation of bolt.When rotation gaily decorated basket bolt coat
When cylinder takes in two inner sleeves in outer sleeve completely, flower basket bolt is contraction state;When rotation gaily decorated basket bolt coat cylinder makes two
Outside the prominent outer sleeve of a inner sleeve, flower basket bolt is elongation state.
Further, the through-hole diameter of U-shaped connecting plate bottom surface is preferably smaller than the inner sleeve diameter of the flower basket bolt.
The specific implementation step for assembling the steel strand prestress flexible draw bar of the utility model is as follows:
(1) U-shaped connection board ends are welded on steel column;
(2) steel strand wires one end is penetrated to the through-hole of U-shaped connecting plate bottom surface;
(3) flower basket bolt of contraction state is penetrated from steel strand wires end;
(4) pressure connection terminal is set in the steel strand wires end at flower basket bolt rear portion;
(5) flower basket bolt is adjusted, flower basket bolt is extended, pretension is applied to steel strand wires.
Steel strand prestress flexible draw bar connection structure provided by the utility model, using the gaily decorated basket spiral shell of adjustable length
Bolt relatively accurately can apply pretension to steel strand wires;It is parallel with steel strand wires substitution by the connection structure of the utility model
Steel tendon and half parallel wire unit reduce steel using amount as steel structure support, as prestressing force flexible draw bar structure, can make
Under the premise of lesser steel and cost, guarantee structure overall stiffness and anti-fatigue performance.

Specific embodiment
With reference to the accompanying drawings, in conjunction with one embodiment, steel strand prestress flexible draw bar provided by the utility model is connected
Binding structure is described in detail.
Referring to Fig.1, steel strand wires are connect by the steel strand prestress flexible draw bar connection structure of the present embodiment with steel column.In steel
U-shaped connecting plate 3 is welded on column 1, one end of steel strand wires 2 penetrates the through-hole of 3 bottom of U-shaped connecting plate, then penetrates from 2 end of steel strand wires
The flower basket bolt 5 of contraction state is arranged pressure connection terminal 4 in 2 end of steel strand wires at 5 rear portion of flower basket bolt, adjusts flower basket bolt 5, make
Flower basket bolt 5 extends, and applies pretension to steel strand wires 2, forms steel strand prestress pull rod.
Wherein flower basket bolt 5 is by internal threaded flower basket bolt outer sleeve and external threaded flower basket bolt inner sleeve
It constitutes, each flower basket bolt outer sleeve spiral connects two flower basket bolt inner sleeves, and flower basket bolt inner sleeve is hollow construction, can
Across steel strand wires 2, every group of flower basket bolt inner sleeve screw thread on the contrary, when the rotation of flower basket bolt outer sleeve its two internal gaily decorated basket
Bolt inner sleeve moves in the opposite direction.
Fig. 2 shows the mutual alignment relation of 3 bottom of U-shaped connecting plate, steel strand wires 2 and flower basket bolt 5.It is installed in steel strand wires
Afterwards, when flower basket bolt 5 is contraction state, steel strand wires are non-tensile states, as shown in Figure 3;Flower basket bolt 5 is adjusted, is allowed to extend
Afterwards, pretension is applied to steel strand wires, state is as shown in Figure 4 after steel strand prestress flexible draw bar tensioning.
It is finally noted that the purpose for publicizing and implementing example is to help to further understand the utility model, this field
Technical staff it should be appreciated that in the spirit and scope for not departing from the utility model and the attached claims, various replacements
It is all possible with modification.Therefore, the utility model should not be limited to embodiment disclosure of that, and the requires of the utility model is protected
The range of shield is subject to the scope defined in the claims.
