Description

Transporter for manufacturing pre-fab structure and manufacturing method using the same {Transporter for manufacturing pre-fab structure and manufacturing method using thereof}

The present invention relates to a transporter for manufacturing a structure and a method for manufacturing a structure, and more specifically, to a transporter for manufacturing a prefab structure and a method for manufacturing a prefab structure using the same.

In recent years, the demand for rapid replacement of bridge deck decks is increasing. For example, the rapid replacement of the deck for emergency recovery due to fire, etc., the replacement of the part of the deck that minimizes traffic control, and the deck of the bridge crossing the upper part of the KTX line (permissible working time per day: 4 hours).

The number of prefabricated structures or precast concrete that can be transported from the factory to the site is limited due to their weight and size. So, the transportation cost accounts for about 20% of the production cost of the floor plate.

In addition, the barrier reinforcement is exposed, multi-stage loading is disadvantageous due to load concentration, etc., and product management is inconvenient and site cost increases because a wide loading site is required during mass production.

Further, a general prefab structure or precast concrete requires manufacturing of various types of formwork and is difficult to automate, increases production cost, and makes it difficult to maintain the same quality.

On the site side, the crane's working radius is large, so a large crane is required compared to the weight of the floor plate, and it is difficult to secure a site for installing a large crane near the bridge.

In addition, the bulk mortar uses a small package mortar because it is difficult to inspect the quality, and the package is removed and agitated, and a large number of scattered shear pockets and connecting parts are stirred, transferred, and poured by manpower.

Therefore, the working conditions such as dust generation during the mortar stirring operation are bad, manpower and time are required, and there is difficulty in maintaining quality.

In addition, it is necessary to minimize vehicle traffic restrictions and reduce environmental pollution. There is no reflection of LCC reduction due to reduced civil complaints and increased durability of the floor plate, and improvement is needed as there are many cases where the construction method is unreasonably determined by simply comparing the construction cost based on the cast-in-place construction method and the direct cost standard.

As an alternative for this, there is a need for a prefab structure mobile manufacturing system that can quickly move to the site and manufacture a prefab structure directly, and an optimized transport means usable for such a prefab structure mobile manufacturing system is also required.
