Precast Temporary Facility Structure and a Construction Method for the Same

Abstract

The present invention relates to a precast temporary facility structure composed of segment members which is manufactured in a predetermined shape in advance at a factory and disposed close to the inner side of a temporary facility wall by fixing means and filled with concrete, and connectors integrally connected to the ends of the segment structures by coupling means to connect the segment members. Accordingly, it is possible to achieve sufficient support force for a long span temporary facility wall having a large entire length and reduce time for curing concrete by the precast, such that it is possible to reduce the construction period.

 a plurality of segment members made of concrete in advance in a predetermined shape and disposed close to a temporary facility wall; and   connectors connecting ends of the segment members with coupling means to integrate the segment members,   wherein a support structure supporting the temporary facility wall is formed by the segment members and the connectors.   
     
     
         2 . The precast temporary facility structure according to  claim 1 , wherein the support structure is in a truss structure formed by the segment members. 
     
     
         3 . The precast temporary facility structure according to  claim 1 , wherein the segment member has a hole therein. 
     
     
         4 . The precast temporary facility structure according to  claim 1 , wherein the coupling means comprises:
 finishing plates, wherein each of the finishing plates has fastening holes around an edge of the finishing plates and integrally coupled to the end of one of the segment members and to an end of one of the connectors; and   iron rods disposed in the segment members and the connectors and connected to the finishing plates.   
     
     
         5 . The precast temporary facility structure according to  claim 1 , wherein the connector has contact portions protruding outwards in order that the end of the segment member may be in close contact with ends of both sides of the connector or with ends of diagonal sides of the connector. 
     
     
         6 . The precast temporary facility structure according to  claim 1 , further comprising at least one stiffener protruding outwards from the outer circumference of the segment member. 
     
     
         7 . The precast temporary facility structure according to  claim 1 , wherein a reinforcing member is disposed inside or outside the segment member. 
     
     
         8 . The precast temporary facility structure according to  claim 1 , wherein the segment member further comprises a tightening member passing through an inside of the segment member. 
     
     
         9 . The precast temporary facility structure according to  claim 8 , wherein the segment member has a seating portion where an end of the tightening member is fixed, and the seating portion is a seating anchor connected to an inner side of the segment member. 
     
     
         10 . The precast temporary facility structure according to  claim 8 , wherein convexo-concave locking protrusions and locking grooves are formed on contact ends of the segment member and the connector, respectively. 
     
     
         11 . The precast temporary facility structure according to  claim 8 , wherein a plurality of convexo-concave shear keys is formed on one side of the segment member. 
     
     
         12 . The precast temporary facility structure according to  claim 11 , wherein the side where the shear keys are formed has nut holes formed inward and fixing bolts each having one end inserted in the nut hole and an opposite end embedded in concrete filled in between the segment member and the temporary facility wall to function as an anchor. 
     
     
         13 . The precast temporary facility structure according to  claim 8 , wherein the tightening member passes through the inside of the connector and the seating portion fixing an end of the tightening member is disposed therein. 
     
     
         14 . The precast temporary facility structure according to  claim 13 , wherein the connector has assembly holes through which the tightening member passes, and the assembly holes are formed at different heights such that the tightening members inserted in different directions do not interfere with each other. 
     
     
         15 . The precast temporary facility structure according to  claim 13 , wherein the connector has a connection hole communicating with the outside, at the center of the connector. 
     
     
         16 . A construction method of a precast temporary facility structure, comprising:
 closely contacting segment members made of concrete in a predetermined shape in advance at a factory to the inner side of a temporary facility wall;   integrally connecting the segment members by using connectors, by connecting ends of the segment members fixed to the temporary facility wall; and   fixing the segment members connected by the connectors to an inner side of the temporary facility wall.   
     
     
         17 . The construction method of a precast temporary facility structure according to  claim 16 , wherein the segment members are connected in a truss structure in the integrally connecting of the segment members by using the connectors. 
     
     
         18 . The construction method of a precast temporary facility structure according to  claim 16 , further comprising tightening the segment members with tightening members, after integrally connecting the segment members by using the connectors.
