Abstract
The utility model provides an arch rib detains a string system steel strand wires and puts an auxiliary device, including a bottom plate and a roof, bottom plate and roof parallel arrangement just have a determining deviation, and bottom plate and roof are the rectangle, weld the backup pad of a rectangular shape respectively between the 4 relative angles of bottom plate and roof, are equipped with an ground tackle trepanning in the middle of the bottom plate, just are equipped with on the roof and detain the steel strand wires through-hole that string system steel strand wires quantity is unanimous with arch rib to the position in ground tackle trepanning. The utility model is used for when arch rib detains hanging system steel strand wires and puts a, block the work anchor through the ground tackle trepanning on the bottom plate, provide the reaction surface for the jack through the roof, interval between roof and the bottom plate is got for the clamping piece and is put and provide operating space, the operation of being convenient for, efficiency of construction and security height.
Description
Technical Field
The utility model relates to a steel strand wires stretch-draw and put a construction technical field, concretely relates to a device that is used for supplementary arch rib to detain hanging system steel strand wires and put.
Background
In the installation process of the arch rib of the steel tube arch bridge, the arch rib needs to be lifted and hung through a buckling and hanging system. One end of a steel strand (a buckle cable) of the buckling and hanging system is connected with the arch rib, the other end of the steel strand is tensioned to adjust the axis of the arch rib to the designed elevation, and then the other end of the steel strand is anchored on an anchor beam on the cable tower. During the subsequent rib butt joint process, if the rib axis is found to exceed the design position, the position of the rib axis can be adjusted downwards by putting the steel strand aside. As shown in fig. 1, the steel strand 6 is anchored on the anchor beam 8 through the working anchor 7, and the clamping piece 9 in the working anchor is required to be taken out firstly when the steel strand 6 is released. The conventional method is to adopt a jack to pull oppositely to thin the steel strand so as to take out the clamping piece, and then the clamping piece is installed back to the working anchor after the steel strand is put to a proper position. The steel strand is difficult to construct in the opposite pulling process, the danger coefficient is high, and once the operation is improper, the steel strand is broken possibly to cause safety accidents.
Disclosure of Invention
The utility model aims at putting to conventional steel strand wires and opening the construction degree of difficulty big, danger coefficient height scheduling problem, design a device that is used for assisting arch rib to detain hanging system steel strand wires specially and puts, guarantee construction safety, swift.
The technical scheme of the utility model as follows:
the utility model provides an arch rib detains system steel strand wires and puts an auxiliary device which characterized in that: the steel strand anchoring device comprises a bottom plate and a top plate, wherein the bottom plate and the top plate are arranged in parallel and have a certain distance, the bottom plate and the top plate are rectangular, a long strip-shaped supporting plate is welded between 4 opposite corners of the bottom plate and the top plate respectively, an anchor device trepanning is arranged in the middle of the bottom plate, the diameter of the anchor device trepanning is consistent with the outer diameter of a working anchor for anchoring the steel strand of the arch rib buckling and hanging system, and steel strand through holes with the same number as the steel strand of the arch rib buckling and hanging system are arranged at the position, which is over against the anchor device.
The utility model discloses simple structure carries on spacingly through ground tackle cover pore pair device on the bottom plate, provides the reaction surface for the jack through the roof, and the interval between roof and bottom plate is got for the clamping piece and is put and provide operating space, and the operation of being convenient for can improve the efficiency of construction, guarantees construction safety.
Drawings
FIG. 1 is a schematic structural view of an arch rib buckling and hanging system, wherein steel strands are anchored on an anchor beam by a working anchor;
fig. 2 is a schematic elevation structure of the present invention;
fig. 3 is a schematic top view of the present invention;
fig. 4 is a schematic view of the usage state of the present invention.
Detailed Description
As shown in fig. 2 and 3, the utility model discloses a bottom plate 1 and a roof 2, bottom plate 1 and 2 parallel arrangement of roof just have a determining deviation, and bottom plate and roof are the rectangle, and the backup pad 3 of welding a rectangular shape respectively between the 4 relative angles of bottom plate and roof, be equipped with an ground tackle trepanning 4 in the middle of the bottom plate, the diameter of ground tackle trepanning 4 is unanimous with the external diameter of the work anchor of anchoring arch rib buckle hanging system steel strand wires, just be equipped with on roof 2 with the arch rib buckle hanging system steel strand wires unanimous steel strand wires through-hole 5 in quantity to the position of ground tackle trepanning 4.
As shown in figure 4, when the utility model is used, the anchor sleeve hole on the bottom plate 1 is just sleeved on the working anchor 7 of the steel strand 6 of the anchoring arch rib buckling and hanging system, which can limit the bottom plate to slide on the anchor beam 8 and play the role of a stabilizing device; a tool anchor 10 is placed on the top plate 2, the steel stranded wires 6 of the arch rib buckling and hanging system respectively penetrate through the steel stranded wire through holes on the top plate and the tool anchor, and the steel stranded wires are gradually tensioned by a jack. When each steel strand is released, the steel strand 6 penetrates through the jack 11, the front end of the jack 11 is supported on the tool anchor 10, the steel strand 6 is firstly stretched, the clamping piece 9 on the working anchor 7 is withdrawn, the clamping piece 9 is taken out, then the jack slowly returns oil to release the steel strand, when the steel strand is released to a designed position, the clamping piece 9 is installed back to the working anchor and is firmly beaten by a hammer, then the jack completely returns oil, and the jack is taken down to finish releasing the steel strand.
Above-mentioned put an in-process, get put clamping piece 9 and need enclose synthetic space in operation at bottom plate 1, roof 2, backup pad 3, consequently the utility model discloses during the preparation, there will be sufficient interval so that constructor manual operation between roof and bottom plate.
