Abstract
The utility model relates to a connector, which comprising an anchor device, anchor plates, a connecting cylinder 7 and reinforcing rings 2. The utility model is characterized in that one end of the connecting cylinder 7 is an OVM anchor composed of a tool anchor plate 3 and a tool clamping sheet 4, and the other end of the connecting cylinder 7 is a P-shaped anchor 8 composed of a P-shaped anchor 8 and a P-shaped anchor plate 9. A pressing spring 5 is arranged on a pressing tool clamping sheet 4 arranged between the P-shaped anchor 8 and the tool clamping sheet 4, and the reinforcing rings 2 are tightly buckled with the outer sides of both ends of the connecting cylinder 7. The connector can reliably stretch a single prestressing tendon or a plurality of prestressing tendons. The utility model has the advantages of convenient operation and prestressing tendon saving.
Description
The utility model belongs to a kind of coupling that is used for opening earlier girder pre-stressed muscle stretch-draw.
At present, formerly open in the concrete prefabricated beam making and adopt coupling stretching single presstressed reinforcing steel shown in Figure 1, adopt traditional star anchor or many presstressed reinforcing steels of coupling stretch-draw shown in Figure 2.Its deficiency is: coupling shown in Figure 1 because of the anchor cup with connect the relative position that causes instrument intermediate plate and presstressed reinforcing steel when screw rod screws and change and can't adjust again; The intermediate plate of coupling shown in Figure 2 then can become flexible because of the play of presstressed reinforcing steel, the actual clamping length of presstressed reinforcing steel is diminished and easily cause slippage, the instrument presstressed reinforcing steel is when two times tensioning, there is the bite mark of intermediate plate on its surface, do not meet code requirement, in each stretch-draw, put after the instrument presstressed reinforcing steel all need clamping tool anchor slab, instrument intermediate plate, make operation complicated, increased unsafe factor, discarded presstressed reinforcing steel is many.
The purpose of this utility model be to provide a kind of can reliable stretching single and Duo Gen presstressed reinforcing steel in pre-tensioning system construction, and coupling easy and simple to handle, that can save more presstressed reinforcing steel.
For reaching above-mentioned purpose, solution of the present utility model is: coupling shown in Figure 2 is improved, and two ends are the clip type anchor, and to change an end into be that clip type anchor, the other end are P shape anchor, is equipped with a holddown spring between P type anchor and instrument intermediate plate.
Its concrete structure is: this coupling comprises ground tackle, anchor slab, coupling tunnel, reinforcing ring, the OVM anchor that one end of coupling tunnel is made up of instrument anchor slab, instrument intermediate plate, the P type anchor that the other end of coupling tunnel is made up of P type anchor, P anchor slab, holddown spring places compaction tool intermediate plate between P type anchor and instrument intermediate plate, and reinforcing ring links closely outside the coupling tunnel two ends.
Owing to adopt said structure, the utlity model has following advantage: during use, the instrument presstressed reinforcing steel is passed the P anchor slab and installs P type anchor by position shown in Figure 3, and the work presstressed reinforcing steel passes the instrument anchor slab, and instrument intermediate plate wedge advances the taper hole clamping work presstressed reinforcing steel of instrument anchor slab; For avoiding the holddown spring unstability, work presstressed reinforcing steel and instrument presstressed reinforcing steel protruded length are long slightly, and it is loosening to prevent it that holddown spring is placed between P type anchor and the instrument intermediate plate compaction tool intermediate plate, and holddown spring is the counter-force seat with the P anchor slab directly; Simple in structure, mounting or dismounting are convenient, every pair of instrument intermediate plate all has a holddown spring, make its thrust impartial and do not disturb mutually, thereby can reliable stretching single and Duo Gen presstressed reinforcing steel, and easy and simple to handle, can save more presstressed reinforcing steel.
Below, the architectural feature to the coupling of the utility model is described further in conjunction with the accompanying drawings and embodiments.
Fig. 1, Fig. 2: existing joiner structure schematic diagram.
Fig. 3: the utility model joiner structure schematic diagram.
Embodiment
A kind of coupling, as shown in Figure 3, this ground tackle comprises: ground tackle, anchor slab, coupling tunnel 7, reinforcing ring 2, the OVM anchor that one end of coupling tunnel 7 is made up of instrument anchor slab 3, instrument intermediate plate 4, the P type anchor 8 that the other end of coupling tunnel 7 is made up of P type anchor 8, P anchor slab 9, holddown spring 5 places compaction tool intermediate plate 4 between P type anchor 8 and the instrument intermediate plate 4, and reinforcing ring 2 links closely outside coupling tunnel 7 two ends.Among the figure, the steel strand that maybe connect in 1,6 minute.
Aforesaid coupling, its coupling tunnel 7 are 2 half opposite openeds, instrument anchor slab 3 in the coupling and P anchor slab 9 can be single hole also can be porous.
Claims (1)
1, a kind of coupling, comprise ground tackle, anchor slab, coupling tunnel (7), reinforcing ring (2), reinforcing ring (2) links closely outside coupling tunnel (7) two ends, it is characterized in that: the OVM anchor that an end of coupling tunnel (7) is made up of instrument anchor slab (3), instrument intermediate plate (4), the P type anchor that the other end of coupling tunnel (7) is made up of P type anchor (8), P anchor slab (9), holddown spring (5) place compaction tool intermediate plate (4) between P type anchor (8) and the instrument intermediate plate (4).
