Field of the Invention The present invention relates to a jig for pulling up structures and a method of replacing a jig using the same, and more particularly to a jig for lifting a structure, And more particularly, to a structure jig for jig replacement or safety check of a bridge capable of stably installing the cylinder on a lower structure having various cylinders and a method for replacing the jig.

The bridge is a shock absorber that absorbs or reduces the load and deformation acting on the upper structure of the bridge to prevent excessive force from being transmitted to the lower structure of the bridge and to relieve the local deformation of the upper structure. It is essential for large bridges.

One such pad device is a pad-shoe type pad. This pad device is briefly described as an example. The pad device is coping with an upper member fixed to the lower surface of the bridge superstructure, And a bearing pad provided between the upper member and the lower member and supporting a compressive force and a deforming force of the bridge.

The upper member of the above-mentioned quay apparatus is provided with a method of installing the upper member of the quay apparatus at the fixed portion embedded in the bridge upper structure and a method of installing the anchor at the upper member of the quay apparatus at the time of installing the bridge, .

However, in the case of replacing the existing system, the anchor of the upper part of the system is embedded in the upper part of the bridge at the time of bridge installation, Respectively.

Therefore, in order to dismantle the upper member of the installed quadrangles in the above-described manner, the lower surface of the bridge upper structure is subjected to concrete breaking work using a breaker, and when an anchor embedded in the bridge upper structure is exposed, , The upper part of the apparatus was disassembled by disassembling, but this conventional method caused damage to the bridge overhead structure due to excessive vibration striking.

The hydraulic jack is installed in close contact with the connecting hole, the connecting hole being formed with an inserting hole through which the inserting hole is formed.

The above-described conventional apparatus for disassembling the upper member of a co-ordinate apparatus is configured to disassemble the upper member of the co-ordinate apparatus by pulling the magnifier and the connecting member through the hydraulic jack and the tensile member. However, There is a problem that the installation of the disassembling device and the disassembling time are excessively required in the entire work process.

In addition, there is a problem that a dismantling device is installed and dismounted, a highly trained artisan must install a dismantling device directly to dismantle the work, and when tensioning the tensile material with a hydraulic jack, There is a fear that the tensile material may be broken and the tensile material may be broken due to the weakening of the tensile material at the time of long-term use, thereby causing a safety accident.

In order to solve the above problems, if the apparatus for disassembling the upper member of the coordinate system apparatus has been developed, the apparatus for disassembling the upper member of the coordinate system apparatus according to the related art is formed in a "b" shape as a whole, The upper surface of the bridge upper structure and the upper surface of the cylinder are in contact with each other. The upper surface of the bridge upper structure and the upper surface of the cylinder are in contact with each other.

Therefore, after the fixing shaft 32a is inserted into the hole of the mounting plate 16 and is coupled by a fastening member such as a nut or a rivet, a connecting rod 34 is installed so as to pass through a pair of supporting blocks 32 arranged to face each other The pair of support members 10 are connected to each other.

Since the coupling protrusion 34a is formed at one end of the coupling block 34 so as not to pass through the hole of the support block 32, the locking protrusion 34a is formed stepwise from the other end of the coupling block 34 When the pair of support blocks 32 are passed through, the engagement protrusion 34a formed at one end of the linkage 34 is engaged with one support block 32. [

Thereafter, when the nut member 38 is fastened to the thread 36 formed at the other end of the connecting rod 34, the gap between the pair of the supporting blocks 32 is narrowed, Lt; / RTI >

The angle adjusting portion 50 includes a curved surface portion 52 which is provided in the support block 32 facing the support projection 14 and whose contact portion is variable along the extending direction of the linkage 34, And a reinforcing panel member (54) provided on the support projection (14) to be interposed between the support projection (14).

The supporting projection 32 is formed on the circumferential surface of the supporting block 32 which is in close contact with the reinforcing panel member 54 It is possible to adjust the extending direction of the connecting rod 34 at various angles while varying the contact portion of the supporting block 32 even when the pair of supporting members 10 are disposed apart from each other.

Accordingly, the operator can arrange the plurality of support members 10 at various positions on the substructure 72 of various structures, and connect the pair of support members 10 to the linkage 34 to provide a tensile force.
