The present invention is a truss structure assembly method and a truss structure construction method using the truss structure to be assembled by pressing the outer circumferential surface of the truss member with a pressing member while receiving the truss member both ends of the truss structure facing each other in the joint support It is about.

Description

Temporary assembly device of truss structures and consturction method of truss structures construction methode approximately using temporary assembly device}

The present invention relates to a truss structure construction method using a truss structure and a truss structure using the truss structure for pressing the outer circumferential surface of the truss member with a pressing member while receiving the truss member opposite ends of the truss structure is mounted to each node support portion It is about.

In general, bridge structures mainly used in bridge construction include PCS box girder bridge, steel composite plate girder bridge, steel composite box girder bridge, and truss bridge using pipe, and the truss bridge triangulates a straight truss member in one plane. Since the truss structure that is continuously connected and assembled in the form must be manufactured, it is not applied frequently because the manufacturing difficulty and manufacturing cost are higher than other bridge types.

However, St.Kilian Viaduct, which was completed in 2006 in Germany, has a large number of truss members in order to accurately support the truss members of heavy, upper, and present trusses at the welding position, as shown in FIG. There was a problem that clubs were required.

In order to move the truss structure manufactured as described above to the installation site, as shown in Figure 2, the support structure is specially manufactured to maintain the welding line between the truss members even during the inter-block welding connection of the truss structure, and high There is a problem in that the construction period and construction cost increases because the complex process to accurately install in the position where the bridge is seated in the complex.

In addition, in order to connect and assemble the truss members 11 and 11 'to manufacture the truss structure, as shown in FIG. 3, a support plate having bolt holes perforated at the end of the truss members 11 and 11' ( There is a method of welding and attaching each of the truss members after welding and attaching the welded support plate 30 to the connecting plate 31 for temporary assembly.

However, in the above method, when welding along the circumference of each truss member, intermittent welding in which the welding line is broken due to the connecting plate connected to the support plate is inevitable, so that the welding quality is not easy and the truss members are horizontally or inclined. Difficulty of welding depending on the installation location is much higher than other structural types, and automatic welding is impossible in principle due to interference of welding rod and connecting plate. Therefore, it is difficult to secure welding quality and difficult to secure skilled workers because it is necessary to rely solely on manual welding. There was this.

In addition, the welding part alignment using the connecting plate not only takes a lot of time and effort for welding the support plate attached to the truss member and welding the truss member, but also removing the support plate and grinding the support plate welding part, and also for welding the support plate. There was a problem that the permanent damage of the base material remains.

In view of the above-described defects in the related art, the object of the present invention is to eliminate the need for expensive copper bar installation or support plate, thereby reducing the construction cost and eliminating the need for grinding after removing the support plate. Therefore, to provide a construction method of the truss structure using the temporary assembly device and the temporary assembly device of the truss structure that can prevent damage to the base material.

In addition, another object of the present invention, the both ends of the truss member seated on each node support portion in the non-stressed state, as well as before the welding of the pre-assembled truss structure can be corrected for the shape and position of the correct truss structure The present invention provides a temporary assembly device for a truss structure and a construction method of a truss structure using the temporary assembly device.

In addition, another object of the present invention, by pre-assembling both ends of the truss member of the opposing truss structure to maintain a constant root spacing of the welded portion to enable precise construction of the truss structure, and the pair of receiving parts of the temporary assembly portion pressure rotation High quality butt welding without rotation of the welding line can be obtained by rotating the roller and welding machine installed in the temporary assembly part, and precise welding by welding machine by easily fixing members with the same outer diameter and different thickness. Since it is possible to provide a construction method for the truss structure using the temporary assembly device and the temporary assembly device of the truss structure that can improve the welding quality.

The temporary assembly device of the truss structure of the present invention,

A device for temporarily assembling a truss structure by connecting a plurality of truss end portions,

Temporary assembling unit for pre-assembled to connect the ends of the truss member to maintain the root spacing of the truss member,

A pair of accommodating parts respectively surrounding both ends of the plurality of truss members;

A connection piece connecting the pair of accommodation portions;

It is characterized in that it comprises a pressing member which is fastened to each of the plurality of fastening holes of the receiving portion to press the outer peripheral surface of the truss member.

In addition, the construction method of the truss structure using the temporary assembly device,

Installing a node support for each node of the truss structure to maintain the stress acting on the truss structure in a stress-free state;

Mounting the truss member of the truss structure to the node supporting portion, and then surrounding the outer circumferential surfaces of both ends of the truss member with a pair of accommodation portions of the provisional assembly portion to couple and guide the guide holes of the accommodation portion with bolts / nuts;
